This study aimed to explore the effects of the DECO-MOM app on personal and community health behaviors, quality of life, subjective health status, depression, anxiety, and e-learning satisfaction, guided by the revised protection motivation theory. Methods/Design: This non-randomized controlled study employed a pre-post-test design with experimental and control groups. The study analyzed data from 31 participants in the experimental group and 34 in the control group after a four-week mobile application intervention conducted from September 26 to October 24, 2023, in three cities in South Korea. Results: The experimental group demonstrated significant improvements in personal environmental health behaviors (p = .003), community environmental health behaviors (p = .001), quality of life (p = .043), and e-learning satisfaction (p = .005) compared to the control group. Significant increases were observed in subcategories such as lifestyle (p = .005), dust management (p < .001), reduction efforts (p = .001), involvement (p = .007), recycling (p = .005), reuse (p = .035), content satisfaction (p < .001), and communication satisfaction (p = .039). However, no significant increases were found in subjective health status, depression, or anxiety. Discussion: The integration of tailored educational content delivered via mobile technology presents a viable strategy for prenatal health promotion. Future studies should explore the long-term impacts and scalability of such mobile-based interventions. Trial registration : Trial registration Number: KCT0007725, Registered September 22, 2022.

Environmental health Women Pregnancy Health behaviors Mobile application Figures Figure 1 Figure 2 Background The unfolding crisis of climate change presents unprecedented challenges to public health, particularly for vulnerable populations such as pregnant women. The American National Association for Environmental Health has recognized environmental health as encompassing the effects of physical, chemical, biological, and psychosocial factors on human health, a definition that becomes increasingly pertinent as we face escalating environmental risks [ 1 ]. Pregnant women are of particular concern due to their heightened vulnerability to adverse outcomes from environmental exposures [ 2 , 3 ]. Climate change exacerbates the spectrum of environmental hazards, from pollution to heatwaves, posing significant threats to maternal and fetal health including neonatal stress and preterm birth [ 4 ]. The need for effective interventions is underscored by a growing body of evidence linking environmental pollutants with adverse pregnancy outcomes, including preterm birth, low birth weight, and developmental issues in offspring [ 2 , 3 ]. Environmental pollution and environmental health factors such as fine particulate matter, air pollution, heavy metals, and chemicals have been shown to contribute to depression, anxiety, and stress in pregnant women [ 5 ]. This situation calls for innovative solutions that can empower pregnant women to navigate physical and psychological risks effectively. Awareness of harmful substances during pregnancy motivates environmental health behaviors [ 6 ]. Research on environmental health interventions for pregnant women is scarce. Providing information about exposure to endocrine disruptors in pregnant women's diets increased environmental behaviors [ 7 ]. In-person environmental health childbirth classes increased environmental awareness, intention, and behavior among pregnant women [ 6 ]. Childbirth education using virtual Zoom meetings and cartoon booklets also increased environmental health vulnerability awareness, self-efficacy, and community health behaviors [ 8 ]. It is imperative to consider the potential of mobile health (mHealth) interventions in bridging the gap between environmental health risks and protective health behaviors from environmental hazards. The advent of mHealth offers a promising avenue for enhancing health literacy and facilitating proactive health management, especially in contexts where traditional healthcare access may be limited or where environmental risks are under-recognized [ 9 ]. A mobile application, the quintessential mHealth, is needed to leverages the ubiquity and accessibility of mobile technology to educate pregnant women about environmental toxins and promote adaptive health behaviors. However, we could not found any mobile application for pregnant women regarding climate change and environmental health. Therefore, the protocol for mobile application named Deep ECOlogy MOM application (DECO-MOM app) interventions was developed by draws upon the revised protection motivation theory (rPTM) as the theoretical foundation [ 10 ]. Rogers suggests that perception of the severity, susceptibility, response efficacy, self-efficacy, costs, and benefits to health threats can motivate protective health behaviors [ 11 ]. By situating the DECO-MOM app within the broader discourse on environmental health, climate change, and digital health innovations, this introduction sets the stage for a nuanced exploration of how technology-driven interventions can make a tangible difference in the lives of pregnant women, offering them tools to safeguard their health and that of their fetus in an increasingly complex environmental landscape. Therefore, this study aimed to explore the effects of DECO-MOM app on environmental health behavior (personal and community health behavior), psychological health (quality of life, subjective health status, depression, and anxiety,), and e-learning satisfaction (Fig. 1 ). Methods Study design This study was non-randomized controlled study with experimental and control group pre-post-test design. This study adhered to the Transparent Reporting of Evaluations with Nonrandomized Designs (TREND) guidelines [ 12 ]. The study protocol was registered in the Korean Clinical Research Information Service at September 22, 2022 (KCT0007725: https://cris.nih.go.kr/cris/search/detailSearch.do?seq=22378&status=5&seq_group=22378&search_page=M ) [ 13 ]. Setting Participants were recruited from three the public health care centers of Chuncheon, Jeonju, and Gongju cities in Gangwon, Jeonrabuk, and Chungcheongnam Province respectively in South Korea. The public centers provided maternal-child healthcare service operating birth education to pregnant women. Researchers were permitted for study and data collection from the healthcare centers and participated prenatal education as lecturers. Researchers provided a mobile application QR code of website address for experimental group after written consent to participate the study and treatment as usual (TAU) education program for the control group. Inclusion and exclusion criteria The participants were included as follow; 1) pregnant women in the gestational aged 4–36 weeks 2) aged over 20 years, 3) have a smart gadget, and 4) Korean language literacy. The exclusion criteria were 1) hospitalized due to physical or psychological health problems and 2) currently receiving medical treatment due to fetal or maternal disease. Allocation The convenience sampling was used allocate 1:1 parallel allocation. The participants recruited from Chuncheon city were allocated to the control group applied only TAU and the participants from Jeonju and Gongju cities in South Korea were allocated to the experimental group applied mobile application. These three cities were middle sized urban-rural cities and similar socioeconomic and cultural status to avoid potential heterogeneous bias. The researcher contacted the pregnant women and explain the study's purpose, procedure, and benefits. The pre-test was performed before mobile application and TAU, intervened for 4 weeks, and post-test just after intervention between September 26 and October 24, 2023 (Fig. 2 ). Sample size The G*Power 3.1.4.9 [ 22 ] calculated the sample size as 32 and 32 in both groups with designated a one-tailed test, the independent t-test, 0.59 effect size (f), 0.75 power, 0.05 significance level, and a 1:1 allocation ratio [ 23 ]. The effect size (Cohen’s d) was calculated by 18.45 ± 13.13 and 9.68 ± 8.24, resulting in a Cohen’s d of .59 according to the previous study [ 6 ]. The sampling was 35 and 35 participants in the both group considering conservative rate of 10%. Four participants among the mobile group the reasons of another schedules of hospital visit or house chores. The participants of 31 in the experimental group and 34 in the control were analyzed. The adherence rates for experimental and control group were 88.57% and 97.14%. Intervention Intervention group The DECO-MOM intervention was designed as a four-week program, delivered via a mobile application, aimed at educating pregnant women on the environmental toxins and promoting adaptive environmental health behaviors. the Android system was used to develop the application. Grounded in the revised protection motivation theory (rPMT), the program operationalizes the theory’s constructs—severity, susceptibility, response efficacy, self-efficacy, costs, and benefits [ 11 ]—into weekly themes that progressively aimed to: enhance understanding of environmental risks, motivate protective health behaviors, balance the perceived benefits against costs of such behaviors, and empower both individual and communal action towards environmental health. This intervention was supported by weekly telephonic follow-ups by a research assistant and facilitated through the widespread KakaoTalk social networking service in Korea, ensuring participant engagement and adherence to the program protocols. The "DECO-MOM environmental prenatal health program" structured as a mobile application designed to educate pregnant women on climate change and environmental health over a four-week period. Each week targets different aspects of environmental health through varied educational methods to engage participants. In the first week, the focus was on raising awareness regarding the reproductive health problems of maternal, fetus, and child (severity). The potential harms from chemicals, electromagnetic waves, and unsafe foods, along with discussing reproductive and general health issues (susceptibility). This was delivered through an orientation session, cartoons for visual learning, explanations for depth understanding, a 5-minute video developed by a researcher, and a question-and-answer segment for interaction, each segment lasting 30 minutes. The second week aimed to empower women with knowledge on avoiding environmental toxins and enhancing their health and that of their fetus (response efficacy), addressing topics such as empowering preventive judgment and control (self-efficacy). A 5-minute video developed by a researcher, cartoons, and explanations were used, followed by a question-and-answer session, mirroring the first week's duration and teaching methods. Week three discussed the trade-offs and benefits of making lifestyle adjustments, focusing on the positive (benefits) and negative aspects (costs) of unhealthy environmental behaviors and highlighting the psychological and physical gains from healthier choices. The session used a 5-minute video developed by a researcher, cartoons, explanations, and a Q&A format for delivery, each lasting 30 minutes. The final week broadens the scope to include changes in personal and community behavior to avoid climate change and exposure to environmental toxin, touching on lifestyle adjustments and community engagement in environmental health practices (motivated health behaviors). It leveraged a 5-minute video developed by a researcher, cartoons, explanations, a question-and-answer segment, introduces a trophy system likely for motivation or achievement recognition, and concludes with a wrap-up session. Each method was designed to last for 30 minutes. Overall, the program was meticulously designed to educate, engage, and empower pregnant women regarding climate change and environmental health, utilizing a blend of educational methods to cater to different learning preferences and effectively communicate complex information (Table 1 ). Control group For the control group, Treatment As Usual (TAU) was administered through in-person instruction over a four-week period. These sessions took place in the maternity class room at the public health center, each lasting two hours and led by two professors specializing in women's health and a midwife. The curriculum covered a range of topics including: 1) comprehension of pregnancy and fetal development; 2) managing pain during childbirth, alongside techniques for relaxation and breathing throughout labor; 3) care after childbirth and breastfeeding practices; and 4) caring for a newborn infant. Measurements The questionnaires were distributed via online survey using a Naver Form respectively through the KakaoTalk messenger. The online survey eook from 10 to 15 minutes. Online gift worth 7 dollars was provided to the participants twice after the pre- and post-test. Primary outcomes Personal environmental health behavior Personal environmental health behavior was measured using the Women's Environmental Health Behavior (WEHB) scales [ 14 ]. The WEHB consists of four factors: 7 lifestyle, 4 personal hygiene, 3 diet, and 3 dust-related behaviors (total 14 items). The WEHB was measured by a Likert scale, ranging from 1 (not at all) to 5 (strongly agree). Total scores ranged from 14 to 60, the higher score meaned the higher personal environmental behavior. The Cronbach’s alpha values for internal consistency reliability were .90 in original scare and .88 in this study. Community environmental health behavior Community environmental health behavior was measured using the Women's Environmental Health Behavior (WEHB) scales [ 14 ]. The WEHB consisted of four factors with 5 reduction, 5 involvement, 3 recycling, and 3 reuse behaviors (total 16 items). The WEHB was measured by a Likert scale, ranging from 1 (not at all) to 5 (strongly agree). Total scores ranged from 16 to 90, the higher score meaned the higher community environmental behavior. The Cronbach’s alpha was .90 in original scare and .89 in this study. Secondary outcomes Quality of life Quality of life was measured using the EuroQol-5D (EQ-5D) [ 15 ] and the Korean version of the EQ-5D was used [ 16 ]. The EQ-5D consists of 5 items with mobility, self-care, usual activity, pain/discomfort, anxiety/depression. The EQ-5D was measured using a Likert scale, ranging from 1 (not at all) to 4 (nearly every day). Total scores ranged from 5 to 20, with higher scores indicating lower quality of life. Cronbach’s alpha was .61 in original scare and .75 in this study. Subjective health status Subjective health status was measured using EQ-VAS was used [ 15 ] and the Korean version of the EQ-VAS was used [ 16 ]. EQ-VAS had one question of ‘The worst health you can imagine’ and numbered from 0 (the worst health respondent can imagine) to 100 (the best health respondent can imagine). When presenting data had the central tendency, it could be the mean value and the standard deviation or, if the data was skewed, the median values and the interquartile range (IQR). Depression Depression was measured using ultra short depression screener Patient Health Questionnaire (PHQ-2) [ 17 ] and the Korean version of the PHQ-2 was used [ 18 ]. A total score of 3 or greater should prompt administration of the full PHQ-9, as well as a clinical interview to determine whether a mental disorder is present. The PHQ-2 was measured using a Likert scale, ranging from 1 (not at all) to 4 (nearly every day). Total scores ranged from 4 to 8, with higher scores indicating higher depression. Cronbach’s alpha was .61 in original scare and .82 in this study. Anxiety Anxiety was measured using the General Anxiety Disorder-7 (GAD-7) [ 19 ] and the Korean version of the GAD-7 will be used [ 20 ]. The GAD-7 had seven items using a Likert scale, ranging from 1 (not at all) to 4 (nearly every day). Total scores ranged from 7 to 28, with higher scores indicating higher anxiety. Cronbach’s alpha was .97 in original scare and .85 in this study. E-learning satisfaction E-learning satisfaction was measured using the E-Learning Satisfaction Scale (eLSS) (17 items) [ 21 ]. The eLSS consisted of three factors with 8 content, 5 interface, and 4 communication (total 17 items). The eLSS was measured by a Likert scale, ranging from 1 (not at all) to 5 (strongly agree). Total scores ranged from 8 to 40, with higher scores indicating greater content satisfaction. Cronbach’s alpha for internal consistency reliability was .93 in original scare and .95 in this study. General and obstetric characteristics The general characteristics were elicited self-reported information, including age, present disease, and employment status. The obstetric characteristics included gestational age and number of children. Ethical consideration This study was approved by the Institutional Review Board of Jeonju University (jjIRB-231214-HR-2023-1014) and adhered to the Declaration of Helsinki. Statistical analysis This study used SPSS for Windows version 27.0 (IBM Corp., Armonk, NY, USA). The homogeneity test was performed using t-test and chi-square test between the two groups. Shapiro-Wilk test was used to test normality, linearity, and residual independence. The independent t-test was used for test the study hypothesis. Hypothesis 1 The mobile group would have higher scores for personal and community environmental health behaviors than the TAU group. Hypothesis 2 The mobile group would have higher scores for quality of life, subjective health status than the TAU group. Hypothesis 3 The mobile group would have lower scores for depression and anxiety than the TAU group. Hypothesis 4 The mobile group would have higher scores for e-learning satisfaction than the TAU group. Results Homogeneity Between Groups The characteristics compared include age, gestational age, number of children, present disease, employment status, personal environmental health behavior (with subcategories: lifestyle, personal goods, diet, dust), community environmental health behavior (with subcategories: reduction, involvement, recycle, reuse), quality of life, subjective health status, depression, anxiety, and e-learning satisfaction. The results indicate no significant differences between the control and experimental groups across most variables, suggesting homogeneity in terms of demographics and baseline measures (Table 2 ).

Effects of the “DECO-MOM” Prenatal Mobile Program The total score of personal environmental health behavior was significantly increased from 55.85 (SD = 6.48) in the control group to 62.32 (SD = 10.38) in the experimental group (p = .003). Subcategories as lifestyle (p = .005) and dust (p < .001) also showed significant improvements. Total scores of community environmental health behavior was significantly improved from 54.18 (SD = 5.58) in the control group to 60.48 (SD = 9.27) in the experimental group (p = .001). Improvements were noted across all subcategories; reduction (p = .001), involvement (p = .007), recycle (p = .005), and reuse (p = .035). Score of quality of life was increased in the experimental group (M = 7.53, SD = 2.03) compared to the control group (M = 6.55, SD = 1.76) (p = .043). Total score of e-learning satisfaction was increased from 57.76 (SD = 11.71) to 65.10 (SD = 8.13) significantly (p = .005). Subcategories as content satisfaction (p < .001) and communication satisfaction (p = .039) increased significantly in the experimental group compared to the control group. There were no significances in subjective health status, depression, and anxiety (Table 3 ).

Discussion In this study, the application of the DECO-MOM app for environmental health of pregnant women increased environmental health behaviors in personal and community aspects, quality of life, and increased satisfaction with the app, while psychological health, such as quality of subjective health status, depression, and anxiety, did not show statistically significant changes. Therefore, study hypothesis 1 and 4 were supported, however, hypothesis 2 and 3 were not supported. The DECO-MOM application, by effectively enhancing personal and community environmental health behaviors, illustrated the viability of leveraging technology to disseminate critical health information and foster behavioral change at a personal and communal level. Furthermore, this study's findings on e-learning satisfaction provided insights applicable to health education contexts, including the elements critical to user satisfaction and engagement in digital learning environments. The effectiveness of this study is attributed to the rPMT, which recognizes that pregnant women are vulnerable to climate change and environmental pollution and perceive real risks to their health [ 11 ]. Personal lifestyle and health behaviors to prevent micro dust triggered health behavior response efficacy, and community environmental health behaviors of reducing, engaging, recycling, and reusing stimulated self-efficacy to respond to climate change [ 11 ]. Climate change encompasses a broad spectrum of environmental alterations, including rising temperatures, increased exposure to pollutants, and the proliferation of vector-borne diseases, all of which pose significant health risks. For pregnant women, these environmental stressors can lead to adverse pregnancy outcomes, such as preterm birth, low birth weight, birth defects [ 24 ], and developmental issues in children [ 25 ]. The susceptibility of pregnant women to these environmental factors was attributed to physiological changes during pregnancy that can alter their response to heat, pollutants, and infectious agents. The intrauterine environment, crucial for fetal development, was sensitive to external environmental conditions, making it imperative to protect maternal health from the adverse effects of climate change [ 25 ]. The results of positive e-learning satisfaction reported by participants further validate the design and content delivery approach of the DECO-MOM program. This satisfaction is indicative of the program's ability to engage users effectively, a critical factor in the success of any health intervention [ 26 ]. This study showed that content satisfaction and communication satisfaction were effective, but interface satisfaction was not, suggesting that it is necessary to use more convenient and attractive technologies for users when developing environmental health apps. The positive reception of the app's content and communication suggests that user-centered design principles, which prioritize the needs and preferences of the target population, are essential in the development of effective mHealth interventions. While previous studies in digital healthcare for pregnant women have shown benefits on depression [ 28 ], anxiety [ 28 , 29 ], and subjective well-being [ 30 ], this study did not show significant psychological effects. The lack of effect on psychological health outcomes in this study could be attributed to the lack of social support during app use. Communication was noted as a key factor affecting the sustainability of mobile apps, so future research should incorporate this factor into the design and evaluation of tools [ 28 ]. Mental health experts ought to be strategically involved in mitigating the adverse effects of climate change by delivering essential psychological assistance and incorporating mental health aspects into the broader framework of climate resilience strategies [ 31 ]. The low levels of subjective well-being and happiness globally were linked to exposure to environmental factors during pregnancy [ 32 ]. Implementing mobile health interventions that focus on environmental health during pregnancy could enhance healthcare quality. Additionally, these interventions can encourage women to take a more active role in managing their own health, ultimately leading to empowered attitudes, healthier environmental health behaviors [ 32 ]. This study had several limitations. Firstly, this study was a small-sized experimental study of pregnant women in three Korean cities the generalizability of the study is limited. There was risk of selection bias of a quasi-experimental study due to difficulties in randomizing subjects as planned in the protocol. Secondly, this study did not consider health equity because it did not include digital literacy or migrant women, because the study only selected participants who could use digital devices and speak Korean. Thirdly, the researchers provided a mobile app and encouraged participation with social networking services, but were unable to provide individualized social support, which did not have a positive impact on mental health. Fourthly, we measured outcomes immediately after the 4-week app implementation, but did not follow up to measure the long-term impact of the app. The DECO-MOM study, through its focus on leveraging a mobile application for prenatal environmental health education, offers several important implications for public health policy, and future research in the domain of environmental health and mHealth interventions. The DECO-MOM study underscore the critical need for incorporating environmental health solutions into public health strategies, especially those aimed at vulnerable populations like pregnant women. The study also indicates that discussing environmental health risks and mitigation strategies should be an integral part of prenatal care. The DECO-MOM study lays the groundwork for future research in key areas. There is a need for further studies to explore the long-term effects of prenatal environmental health interventions on maternal and neonatal outcomes. Such research could provide deeper insights into the potential for mHealth tools to contribute to reducing adverse birth outcomes associated with environmental exposures. In conclusion, the DECO-MOM study not only demonstrates the effectiveness of a mobile application in improving environmental health behaviors and e-learning satisfaction among pregnant women but also reflects the potential of digital health interventions in enhancing environmental health outcomes.

The American National Association for Environmental Health has recognized environmental health as encompassing the effects of physical, chemical, biological, and psychosocial factors on human health, a definition that becomes increasingly pertinent as we face escalating environmental risks [\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]. Pregnant women are of particular concern due to their heightened vulnerability to adverse outcomes from environmental exposures [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e, \u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eClimate change exacerbates the spectrum of environmental hazards, from pollution to heatwaves, posing significant threats to maternal and fetal health including neonatal stress and preterm birth [\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e]. The need for effective interventions is underscored by a growing body of evidence linking environmental pollutants with adverse pregnancy outcomes, including preterm birth, low birth weight, and developmental issues in offspring [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e, \u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e]. Environmental pollution and environmental health factors such as fine particulate matter, air pollution, heavy metals, and chemicals have been shown to contribute to depression, anxiety, and stress in pregnant women [\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e]. This situation calls for innovative solutions that can empower pregnant women to navigate physical and psychological risks effectively.\u003c/p\u003e \u003cp\u003eAwareness of harmful substances during pregnancy motivates environmental health behaviors [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e]. Research on environmental health interventions for pregnant women is scarce. Providing information about exposure to endocrine disruptors in pregnant women's diets increased environmental behaviors [\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e]. In-person environmental health childbirth classes increased environmental awareness, intention, and behavior among pregnant women [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e]. Childbirth education using virtual Zoom meetings and cartoon booklets also increased environmental health vulnerability awareness, self-efficacy, and community health behaviors [\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e]. It is imperative to consider the potential of mobile health (mHealth) interventions in bridging the gap between environmental health risks and protective health behaviors from environmental hazards. The advent of mHealth offers a promising avenue for enhancing health literacy and facilitating proactive health management, especially in contexts where traditional healthcare access may be limited or where environmental risks are under-recognized [\u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eA mobile application, the quintessential mHealth, is needed to leverages the ubiquity and accessibility of mobile technology to educate pregnant women about environmental toxins and promote adaptive health behaviors. However, we could not found any mobile application for pregnant women regarding climate change and environmental health. Therefore, the protocol for mobile application named Deep ECOlogy MOM application (DECO-MOM app) interventions was developed by draws upon the revised protection motivation theory (rPTM) as the theoretical foundation [\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e]. Rogers suggests that perception of the severity, susceptibility, response efficacy, self-efficacy, costs, and benefits to health threats can motivate protective health behaviors [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eBy situating the DECO-MOM app within the broader discourse on environmental health, climate change, and digital health innovations, this introduction sets the stage for a nuanced exploration of how technology-driven interventions can make a tangible difference in the lives of pregnant women, offering them tools to safeguard their health and that of their fetus in an increasingly complex environmental landscape. Therefore, this study aimed to explore the effects of DECO-MOM app on environmental health behavior (personal and community health behavior), psychological health (quality of life, subjective health status, depression, and anxiety,), and e-learning satisfaction (Fig.\u0026nbsp;\u003cspan refid=\"Fig1\" class=\"InternalRef\"\u003e1\u003c/span\u003e).\u003c/p\u003e \u003cp\u003e \u003c/p\u003e"},{"header":"Methods","content":"\u003cdiv id=\"Sec3\" class=\"Section2\"\u003e\n \u003ch2\u003eStudy design\u003c/h2\u003e\n \u003cp\u003eThis study was non-randomized controlled study with experimental and control group pre-post-test design.

environmental health of pregnant women increased environmental health behaviors in personal and community aspects, quality of life, and increased satisfaction with the app, while psychological health, such as quality of subjective health status, depression, and anxiety, did not show statistically significant changes. Therefore, study hypothesis \u003cspan refid=\"FPar5\" class=\"InternalRef\"\u003e1\u003c/span\u003e and \u003cspan refid=\"FPar8\" class=\"InternalRef\"\u003e4\u003c/span\u003e were supported, however, hypothesis \u003cspan refid=\"FPar6\" class=\"InternalRef\"\u003e2\u003c/span\u003e and \u003cspan refid=\"FPar7\" class=\"InternalRef\"\u003e3\u003c/span\u003e were not supported. The DECO-MOM application, by effectively enhancing personal and community environmental health behaviors, illustrated the viability of leveraging technology to disseminate critical health information and foster behavioral change at a personal and communal level. Furthermore, this study's findings on e-learning satisfaction provided insights applicable to health education contexts, including the elements critical to user satisfaction and engagement in digital learning environments.\u003c/p\u003e \u003cp\u003eThe effectiveness of this study is attributed to the rPMT, which recognizes that pregnant women are vulnerable to climate change and environmental pollution and perceive real risks to their health [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e]. Personal lifestyle and health behaviors to prevent micro dust triggered health behavior response efficacy, and community environmental health behaviors of reducing, engaging, recycling, and reusing stimulated self-efficacy to respond to climate change [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e]. Climate change encompasses a broad spectrum of environmental alterations, including rising temperatures, increased exposure to pollutants, and the proliferation of vector-borne diseases, all of which pose significant health risks. For pregnant women, these environmental stressors can lead to adverse pregnancy outcomes, such as preterm birth, low birth weight, birth defects [\u003cspan citationid=\"CR24\" class=\"CitationRef\"\u003e24\u003c/span\u003e], and developmental issues in children [\u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e25\u003c/span\u003e]. The susceptibility of pregnant women to these environmental factors was attributed to physiological changes during pregnancy that can alter their response to heat, pollutants, and infectious agents. The intrauterine environment, crucial for fetal development, was sensitive to external environmental conditions, making it imperative to protect maternal health from the adverse effects of climate change [\u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e25\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThe results of positive e-learning satisfaction reported by participants further validate the design and content delivery approach of the DECO-MOM program. This satisfaction is indicative of the program's ability to engage users effectively, a critical factor in the success of any health intervention [\u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e26\u003c/span\u003e]. This study showed that content satisfaction and communication satisfaction were effective, but interface satisfaction was not, suggesting that it is necessary to use more convenient and attractive technologies for users when developing environmental health apps. The positive reception of the app's content and communication suggests that user-centered design principles, which prioritize the needs and preferences of the target population, are essential in the development of effective mHealth interventions.\u003c/p\u003e \u003cp\u003eWhile previous studies in digital healthcare for pregnant women have shown benefits on depression [\u003cspan citationid=\"CR28\" class=\"CitationRef\"\u003e28\u003c/span\u003e], anxiety [\u003cspan citationid=\"CR28\" class=\"CitationRef\"\u003e28\u003c/span\u003e, \u003cspan citationid=\"CR29\" class=\"CitationRef\"\u003e29\u003c/span\u003e], and subjective well-being [\u003cspan citationid=\"CR30\" class=\"CitationRef\"\u003e30\u003c/span\u003e], this study did not show significant psychological effects. The lack of effect on psychological health outcomes in this study could be attributed to the lack of social support during app use. Communication was noted as a key factor affecting the sustainability of mobile apps, so future research should incorporate this factor into the design and evaluation of tools [\u003cspan citationid=\"CR28\" class=\"CitationRef\"\u003e28\u003c/span\u003e]. Mental health experts ought to be strategically involved in mitigating the adverse effects of climate change by delivering essential psychological assistance and incorporating mental health aspects into the broader framework of climate resilience strategies [\u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e31\u003c/span\u003e]. The low levels of subjective well-being and happiness globally were linked to exposure to environmental factors during pregnancy [\u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e32\u003c/span\u003e]. Implementing mobile health interventions that focus on environmental health during pregnancy could enhance healthcare quality. Additionally, these interventions can encourage women to take a more active role in managing their own health, ultimately leading to empowered attitudes, healthier environmental health behaviors [\u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e32\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThis study had several limitations. Firstly, this study was a small-sized experimental study of pregnant women in three Korean cities the generalizability of the study is limited. There was risk of selection bias of a quasi-experimental study due to difficulties in randomizing subjects as planned in the protocol. Secondly, this study did not consider health equity because it did not include digital literacy or migrant women, because the study only selected participants who could use digital devices and speak Korean. Thirdly, the researchers provided a mobile app and encouraged participation with social networking services, but were unable to provide individualized social support, which did not have a positive impact on mental health. Fourthly, we measured outcomes immediately after the 4-week app implementation, but did not follow up to measure the long-term impact of the app.\u003c/p\u003e \u003cp\u003eThe DECO-MOM study, through its focus on leveraging a mobile application for prenatal environmental health education, offers several important implications for public health policy, and future research in the domain of environmental health and mHealth interventions. The DECO-MOM study underscore the critical need for incorporating environmental health solutions into public health strategies, especially those aimed at vulnerable populations like pregnant women. The study also indicates that discussing environmental health risks and mitigation strategies should be an integral part of prenatal care. The DECO-MOM study lays the groundwork for future research in key areas. There is a need for further studies to explore the long-term effects of prenatal environmental health interventions on maternal and neonatal outcomes. Such research could provide deeper insights into the potential for mHealth tools to contribute to reducing adverse birth outcomes associated with environmental exposures. In conclusion, the DECO-MOM study not only demonstrates the effectiveness of a mobile application in improving environmental health behaviors and e-learning satisfaction among pregnant women but also reflects the potential of digital health interventions in enhancing environmental health outcomes.\u003c/p\u003e \u003cdiv id=\"Sec28\" class=\"Section2\"\u003e \u003ch2\u003eTrial status\u003c/h2\u003e \u003cp\u003eRegistered before recruiting.\u003c/p\u003e \u003c/div\u003e"},{"header":"Abbreviations","content":"\u003cp\u003eDECO-MOM: DEep Ecology-MOM\u003c/p\u003e\n\u003cp\u003eGAD-7: general anxiety disease\u003c/p\u003e\n\u003cp\u003ee-LSS: e-learning satisfaction scale\u003c/p\u003e\n\u003cp\u003eEQ-5D: European quality of life 5-dimension\u003c/p\u003e\n\u003cp\u003eEQ-VAS: European quality of life Visual Analogue Scale\u003c/p\u003e\n\u003cp\u003ePHQ-2: Patient Health Questionnaire-2\u003c/p\u003e\n\u003cp\u003eQR: quick response\u003c/p\u003e\n\u003cp\u003erPMT:\u0026nbsp;the revised protection motivation theory\u003c/p\u003e\n\u003cp\u003eTAU : Treatment As Usual\u003c/p\u003e\n\u003cp\u003eTREND: Transparent Reporting of Evaluations with Nonrandomized Designs\u003c/p\u003e\n\u003cp\u003eWEHB: women\u0026apos;s environmental health behavior\u0026nbsp;\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eEthics approval\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThis study was reviewed by the Institutional Review Board of Institutional Review Board of Jeonju University (jjIRB-231214-HR-2023-1014) and adhered to the Declaration of Helsinki.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConsent to participate\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eParticipants completed written consent.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConsent for publication\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eNot applicable.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eAvailability of data and materials\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThe data that support the findings of this study are available from the corresponding author upon reasonable request.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompeting interests\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThe author declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eFunding\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eThis work was supported by the National Research Foundation of Korea (NRF) Grant funded by the Korea government (MIST) (RS-2023-00239284).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuthor contributions\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eHKK participated in the conception, design of the study\u003c/p\u003e\n\u003cp\u003eHKK and JHK the acquisition of data, drafted the first and final manuscript.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eAcknowledgements\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eNot applicable.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuthor details\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eFirst author:\u003c/p\u003e\n\u003cp\u003eHae Kyung Jo, Ph.D., RN.
