Anxiety and depression are now gradually believed to be the causes of functional dyspepsia (FD). The influence of SWB was ignored in FD patients. To explore the influence of SWB on anxiety, depression, symptom severity and quality of life (QoL) in FD patients. Methods A total of 374 patients with FD were selected according to Roman IV criteria. Satisfaction with life scale and affect balance scale, Generalized anxiety disorders-7, Patient healthy questionnaire-9, Dyspepsia symptoms severity(DSS)and Nepean dyspepsia index(NDI) were used to assess SWB,anxiety, depression, symptoms severity and QoL, respectively. One-way variance analysis, t-test, Pearson’s correlation and multiple linear regression were used to analyze the results. Results Life satisfaction and emotional balance of FD patients were negatively correlated with DSS, anxiety, depression, and NDI for QoL(r=-0.148,-0.330,-0.325,-0.195, all P <0.01), (r=-0.205,-0.545,-0.550, -0.357, all P <0.001), respectively. Multiple linear regression showed that life satisfaction and emotional balance were influencing factors of anxiety(β= -0. 143, P =0.001), (β= -0. 318, P <0.001), and depression(β=-0. 122, P =0.003), (β= -0. 287, P <0.001), respectively. After removing anxiety and depression, life satisfaction and emotional balance were influencing factors of patients' DSS (β= -0.105, P =0.049), (β= -0.180, P =0.001), and QoL(β= -0.117, P =0.023), (β= -0.329, P <0.001) ,respectively. Conclusions FD patients’ SWB negatively affects their disease severity, anxiety and depression, and positively affects their QoL. These results suggested that further strengthening SWB may help reduce symptom severity and improve the QoL of patients, which needs to be confirmed by future follow-up studies. Functional dyspepsia Subjective well-being Anxiety Depression Quality of life Background Psychosocial factors believed as causes of functional dyspepsia (FD) FD is very common clinically in gastroenterology. According to Roman IV diagnostic criteria, its main symptoms are divided into three subtypes: epigastric pain syndrome (EPS) with epigastric burning or pain, postprandial distress syndrome (PDS) with early satiation or postprandial fullness, and an overlapping subtype with two features [1-3]. FD patients often have chronic gastritis when undergoing gastroscopy due to stomach discomfort. FD diagnosis is as easy as chronic gastritis, but FD pathogenesis such as visceral hypersensitivity and abnormal brain-gut interaction is different from gastritis [1]. Patients are often accompanied by anxiety and depression, which were previously thought to be concomitants of FD. With the important progress of brain-gut interaction, stress, anxiety and depression are now gradually believed to be the causes of FD [4-7]. Anxiety and depression have causal effects reducing the incidence of the symptoms in FD patients [8]. The treatments such as acid suppression and some antidepressants can alleviate symptoms of FD patients; however, there is a lack of specific pharmacological interventions to cure the disease, and patients with recurrent episodes may experience a chronic course lasting for decades, which significantly impacts various aspects of patients' daily life and work, thereby compromising their overall quality of life (QoL)[5].Thus, the influence of psychosocial factors on QoL should be paid more attention in FD patients. Subjective well-being (SWB) is a psychological index SWB is a psychological index for individuals to evaluate their own QoL as a whole based on self-determined standards, including life satisfaction and emotional balance, and it is also an important part of social psychological factors [9-11]. The evaluation of life satisfaction is a quantitative evaluation of most aspects of life such as: Whether individuals' life are satisfied with their current life, and want to change their life again [10]. Emotional balance includes negative emotions such as feeling upset and upset about criticism, as well as positive emotions such as: feeling happy when you have completed a task, whether things have gone according to your wishes, and feeling proud of others' praise for your work. The higher an individual's overall score was assessed, the higher the SWB [10-11]. The impact of SWB on FD patients was ignored On the other hand, with the development of the social economy and the increase in social competition pressure, if there is insufficient understanding of SWB, it may decrease[12]; SWB is related to diseases in a two-way relationship, and the SWB decreases in patients with chronic pulmonary diseases, arthritis, and coronary heart disease [9,13]. Lower life satisfaction had a strongly increased risk of moderate/severe depression [14,15]. Because the effect of drug treatment for FD is limited [5,16], patients often suspect that stomach problems are caused by serious diseases such as cancer, affecting their ability and interest in daily life or work. The disease may have a long-term impact on the QoL of patients, interacting with the disease [5,6]. The FD repeatedly and directly affects various aspects of patients' daily life and work, thereby compromising their QoL including the impact of stomach pain and discomfort on daily activities, eating/drinking, and emotional irritability, depression or tension [6]. Kaida et al. [17] showed that the higher the SWB, the higher the QoL. However, there are few studies on the impact of SWB on FD patients. The objective evidence of SWB in previous studies Previous studies have revealed that the SWB was defined as subjective happiness, and it was also objective [18-24]. The SWB was positive with the fractional amplitude of low-frequency fluctuations (fALFF) in the right thalamus, lingual gyrus, posterior mid-cingulate cortex, left postcentral gyrus, planum temporale, and bilateral posterior superior temporal gyrus, which was negative with the left inferior temporal gyrus, right orbitofrontal cortex, and bilateral superior frontal gyrus[18,19]. The SWB was negatively correlated with static functional connectivity between the salience network (SN) and the anterior default mode network (DMN), which was also negatively correlated with the fraction of time that participants spent in a brain state characterized by strong within the DMN and the frontal-parietal network dynamic functional network connectivity (dFNC) [20]. Furthermore, more evidence showed that the SWB was associated with the caudate nucleus [21], and a congenital corpus callosum disorder was associated with decreased SWB [22]. The rating scores of SWB can be predicted by the volume of the left caudate nucleus by promotion focus orientation [24]. Exploring the effect degree of SWB on FD patients’ QoL Currently, there is a lack of specific management to cure FD patients, of which recurrent episodes may significantly compromise their QoL [5,17]. SWB is also objective, which has a strongly increased risk of moderate/severe depression in long follow-up studies [14,15]. Depression may be the cause of FD.SWB influenced QoL in previous studies. However, few studies investigate the influence of SWB on QoL in FD patients, ignoring the influence of SWB. Therefore, we conducted a study aiming to examine the impact of SWB on anxiety, depression, symptoms severity, and QoL in individuals with FD, and establish a foundation for future studies enhancing SWB to improve the QoL in FD patients. Patients and Methods Patients This study recruited 374 patients diagnosed with FD from the gastroenterology outpatient department of the Affiliated Hospital of North Sichuan Medical College between June and December 2022 using a convenience sampling method. According to CONSORT guidelines, inclusion criteria were as follows: (1) adherence to the Rome IV diagnostic criteria for FD, characterized by symptoms such as epigastric distension, early satiety, epigastric pain, or burning sensation lasting more than six months, with consistent symptoms in the past three months; (2) age of 18 years or older; (3) normal language communication and cognitive abilities sufficient to comprehend the research content. Exclusion criteria included: (1) diagnosis of systemic or organic diseases based on biochemical tests, endoscopy, B-ultrasound, and other examinations; (2) presence of gastroesophageal reflux disease, or irritable bowel syndrome; (3) history of abdominal surgery; (4) lactation or pregnancy status; (5) use of non-steroidal anti-inflammatory drugs, glucocorticoids, or other medications. According to previous studies,300 FD patients achieved the minimum sample with a 95% confidence interval to equally split the (50/50) chance [25,26], with a final inclusion of 374 patients. Ethical approval was obtained from the Ethics Committee of the Affiliated Hospital of North Sichuan Medical College (Ethics number: 2021ER074-1), and informed consent was obtained from all participants. Instruments Satisfaction with Life Scale (SWLS) The SWLS created by Diener et al. [10] is a widely used five-item scale assessing overall life satisfaction: whether most aspects of an individual's life are close to the ideal, whether they are satisfied with their current life, whether they have what they want in life, and whether they want to change their life again. Higher scores indicate greater life satisfaction [27, 28]. Affect balance scale (ABS) The ABS developed by Bradburn et al. [27] measures both negative emotions (e.g., feeling upset due to criticism) and positive emotions (e.g., feeling happy after completing work). The scale consists of ten items, with higher negative emotion scores indicating poorer emotional balance and higher positive emotion scores indicating better emotional balance [28]. Generalized anxiety disorder-7 (GAD-7) The GAD-7 evaluates patients' anxiety levels over the past two weeks through seven items, each scored from 0 to 3. Anxiety levels are categorized as none (less than 5 points), mild (5-9 points), moderate (10-14 points), and severe (more than 14 points) [29]. Patient health questionnaire-9 (PHQ-9) The PHQ-9 assesses depressive mood and sleep status over the past two weeks. It includes nine items, each scored from 0 to 3. Results are classified as none (less than 5 points), mild (5-9 points), moderate (10-14 points), and severe (more than 14 points) [30]. D yspepsia symptoms severity (DSS) The DSS evaluates the severity of eight dyspepsia symptoms, including epigastric pain, burning sensation in the upper abdomen, fullness, abdominal distension, nausea, vomiting, and belching. Each symptom is scored from 0 to 3, with higher scores indicating more severe symptoms [31]. 10-item short form of Nepean dyspepsia index (SF-NDI) The SF-NDI assesses the impact of dyspepsia on patients' daily activities. In the past two weeks, patients were assessed on work, study, and ten other aspects, with each item rated on a scale of 1 to 5 points. Higher scores indicate a greater impact of the disease on QoL, reflecting a lower QoL for the patients [32]. Data collection and quality control methods We employed WeChat or telephone surveys for data collection. From September to December 2022, after receiving unified training, research team members conducted one-on-one investigations with patients who had provided informed consent. They patiently explained the purpose and content of the study to respondents, ensuring that no biased or suggestive language was used during questioning. The collected data includes general conditions such as gender, age, and education level of FD patients, SWLS, ABS, GAD-7, PHQ-9, DSS, and SF- NDI scores from FD patients. Statistical analysis Data were analyzed using SPSS 26.0 software. Qualitative data are presented as the number of cases (%), while normally distributed data are represented by mean ± standard deviation. T-tests were used for comparisons between two groups, and one-way ANOVA was applied for comparisons among more than three groups. Pearson correlation coefficients were calculated for correlation analysis. Backward linear regression was employed to analyze the effects of SWB, anxiety, and depression on DSS and QoL. P < 0.05 was considered statistically significant. Results General data analysis of patients' SWB A total of 374 individuals were surveyed; 22 were excluded due to incomplete data, resulting in 352 valid responses, with an effective response rate of 94.12%. A total of 352 FD patients were diagnosed, including 138 males with a mean age of (46.43±11.67) years and 214 females with a mean age of (47.29±8.35) years. Educational levels were distributed as follows: 5.1% (18/352) illiterate/below primary school, 23.6% (83/352) primary school, 40.3% (142/352) middle school, 14.5% (51/352) high school/technical school, and 16.5% (58/352) college or above. Anxiety levels were categorized as follows: no anxiety in 52.2% (184/352) cases, mild anxiety (≥4) in 40.9% (144/352) cases, and moderate/severe anxiety (≥10) in 6.8% (24/352) cases. In 352 cases, 45.5% (160/352) cases showed no depression, 44.3% (156/352) cases scoring 4 or above indicative of mild depression, and 10.2%(36/352)cases scoring 10 or above suggestive of moderate to severe depression. Among these, there were 57 cases with PDS, 122 cases with EPS, and 173 cases in the overlap group. No statistically significant differences were found in life satisfaction (PDS 22.14 ± 3.95, EPS 22.25 ± 4.40, overlap group 22.02 ± 4.36) or emotional balance (PDS 5.07 ± 1.50, EPS 5.44 ± 1.44, overlap group 5.01 ± 1.36) across the three subtypes (all P > 0.05). There were no significant differences in life satisfaction and emotional balance scores between genders and education levels (all P >0.05). The more severe the anxiety and depression symptoms, the lower the life satisfaction and emotional balance (all P <0.05), as shown in Table 1.

Notably, the correlation coefficient for emotional balance was higher than that for life satisfaction (Table 2). Additionally, patient age exhibited a positive correlation with life satisfaction (r=0.176, P =0.001).

However, when anxiety and depression were incorporated into the model, neither life satisfaction nor emotional balance remained significant predictors of DSS (all P > 0.05) (Table 5).

Nevertheless, after accounting for anxiety and depression, neither life satisfaction nor emotional balance retained their significance as determinants of QoL (all P > 0.05) (Table 6).

This study represents the first exploration of the effects of SWB on anxiety, depression, symptom severity, and QoL in FD patients. Our findings indicate that SWB is negatively correlated with anxiety, depression, and symptom severity, which is positively associated with QoL, patients with more severe anxiety and depression symptoms tend to have lower life satisfaction and emotional balance, and dissatisfaction with current life is common among patients with anxiety and depression, leading to reduced life satisfaction, which was following the results in other diseases [ 33 , 34 ]. This study also revealed no significant differences in SWB among the three subtypes of FD, and anxiety had a more significant impact on SWB compared to depression. Therefore, these results suggested that mitigating anxiety and depression may alleviate symptom severity and enhance QoL. Multivariate analysis showed that SWB had a less significant impact on symptom severity and QoL compared to anxiety and depression, of which the fit degree of the model R 2 was low in this cross-sectional study, which suggested that the influence of SWB was easily ignored in FD patients. Medical staff often focused on the influence of anxiety and depression while neglecting the role of SWB in FD patients. However, considering the brain-gut interaction, anxiety and depression are increasingly recognized as contributing factors to the etiology of FD [ 4 , 5 ]. There is an inverse relationship between SWB and resilience in depression [ 34 ]. Lower life satisfaction was associated with a significantly increased risk (OR = 10.4) of moderate/severe depression over a 15-year follow-up of healthy adults [ 15 ]. Given that most FD cases are chronic, SWB can serve as a crucial potential indicator for studying the development and management of FD in future long-term follow-up studies. The determinants of SWB were classified into seven major domains: health and functioning, social support, socioeconomic status, demographic characteristics, personality traits, religious and cultural factors, and infrastructure and geography [ 35 , 36 ]. Socioeconomic status was identified as a significant factor influencing SWB [ 37 , 38 ]. With societal economic development, the prevalence of FD has also increased [ 2 ]. Our findings revealed a positive correlation between patient age and life satisfaction with older individuals reporting higher levels of satisfaction, and higher educational level with higher levels of satisfaction. Additionally, social support emerged as a crucial determinant of SWB [ 39 ]. However, medical interventions aimed at improving socioeconomic status and social support are limited in their effectiveness; therefore, this study primarily focused on assessing the health and functioning of SWB, including mental health aspects such as anxiety and depression. To enhance SWB, psychotherapeutic interventions have demonstrated moderate effects in reducing negative affect and enhancing positive affect among depressed adults [ 40 ]. Educational programs and cognitive interventions have been shown to effectively improve SWB and promote resilience in elderly populations, thereby alleviating depressive symptoms [ 41 ]. A positive optimistic personality trait can also contribute to higher SWB [ 16 , 38 ]. Leisure time physical activity (LTPA) interventions have been found to promote SWB by improving health and functioning [ 42 , 43 ]. Furthermore, Ludwigs et al. [ 11 ] demonstrated that both professional psychological training groups and control groups that repeatedly filled out scales of SWB could effectively enhance SWB without any statistically significant differences between them, and simply reinforcing the concept of SWB can lead to improvements. Therefore, strengthening content awareness of SWB is a simple and feasible approach to improving it. This study had the following limitations: Firstly, the data were derived from a single center of FD patients in one hospital, which may limit the generalizability of the findings. Secondly, this was a cross-sectional study that showed that SWB was negatively correlated with symptom severity, anxiety, and depression and positively correlated with QoL. However, as a cross-sectional study, it is limited in its ability to infer causality; therefore, a longitudinal cohort study is necessary to confirm whether enhancing SWB can reduce the incidence or severity of FD symptoms in future research. Thirdly, although SWB showed a negative correlation with anxiety, depression, and disease impact on QoL, the correlation coefficient in this study was below 0.7, indicating a weaker association. Fourthly, multiple linear regression analysis revealed that when including anxiety and depression, SWB did not significantly influence symptom severity and QoL, suggesting that SWB played a less significant role compared to anxiety and depression. Gastroenterology medical staff tended to focus more on the effects of anxiety and depression on FD while overlooking the impact of SWB. However, SWB associated with anxiety and depression, which are potentially the etiology of FD, and lower life satisfaction was associated with a significantly increased risk of moderate/severe depression over a long follow-up study [ 15 ]. These results suggested that reinforcing the impact of FD patients' SWB may help reduce symptoms, which requires further confirmation in future long-term studies. Conclusions The study indicated that FD patients' SWB was negatively correlated with symptom severity, anxiety, and depression, and positively correlated with QoL. These results suggested that SWB could be considered as a potential indicator for studying the development and management of FD in future research, Furthermore, enhancing the SWB of FD patients through targeted interventions by medical staff may contribute to reducing symptom severity, anxiety, and depression levels while improving their QoL. These potential benefits warrant confirmation through long-term follow-up studies.

According to Roman IV diagnostic criteria, its main symptoms are divided into three subtypes: epigastric pain syndrome (EPS) with epigastric burning or pain, postprandial distress syndrome (PDS) with early satiation or postprandial fullness, and an overlapping subtype with two features [1-3]. FD patients often have chronic gastritis when undergoing gastroscopy due to stomach discomfort. FD diagnosis is as easy as chronic gastritis, but FD pathogenesis such as visceral hypersensitivity and abnormal brain-gut interaction is different from gastritis [1]. Patients are often accompanied by anxiety and depression, which were previously thought to be concomitants of FD. With the important progress of brain-gut interaction, stress, anxiety and depression are now gradually believed to be the causes of FD [4-7]. Anxiety and depression have causal effects reducing the incidence of the symptoms in FD patients [8]. The treatments such as acid suppression and some antidepressants can alleviate symptoms of FD patients; however, there is a lack of specific pharmacological interventions to cure the disease, and patients with recurrent episodes may experience a chronic course lasting for decades, which significantly impacts various aspects of patients\u0026apos; daily life and work, thereby compromising their overall quality of life\u0026nbsp;(QoL)[5].Thus, the influence of psychosocial factors on QoL should be paid more attention in FD patients.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eSubjective well-being (SWB) is a psychological index\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eSWB is a psychological index for individuals to evaluate their own QoL as a whole based on self-determined standards, including life satisfaction and emotional balance, and it is also an important part of social psychological factors [9-11]. The evaluation of life satisfaction is a quantitative evaluation of most aspects of life such as: Whether individuals\u0026apos; life are satisfied with their current life, and want to change their life again [10]. Emotional balance includes negative emotions such as feeling upset and upset about criticism, as well as positive emotions such as: feeling happy when you have completed a task, whether things have gone according to your wishes, and feeling proud of others\u0026apos; praise for your work. The higher an individual\u0026apos;s overall score was assessed, the higher the SWB [10-11].\u0026nbsp;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe impact of SWB on FD patients\u003c/strong\u003e \u003cstrong\u003ewas ignored\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eOn the other hand, with the development of the social economy and the increase in social competition pressure, if there is insufficient understanding of SWB, it may decrease[12]; SWB is related to diseases in a two-way relationship, and the SWB decreases in patients with chronic pulmonary diseases, arthritis, and coronary heart disease [9,13]. Lower life satisfaction had a strongly increased risk of moderate/severe depression [14,15]. Because the effect of drug treatment for FD is limited [5,16], patients often suspect that stomach problems are caused by serious diseases such as cancer, affecting their ability and interest in daily life or work. The disease may have a long-term impact on the QoL of patients, interacting with the disease [5,6]. The FD repeatedly and directly affects various aspects of patients\u0026apos; daily life and work, thereby compromising their QoL including the impact of stomach pain and discomfort on daily activities, eating/drinking, and emotional irritability, depression or tension [6]. Kaida et al. [17] showed that the higher the SWB, the higher the QoL. However,\u0026nbsp;there are few studies on the impact of SWB on FD patients.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe objective evidence of SWB in previous studies\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003ePrevious studies have revealed\u0026nbsp;that the SWB was defined as subjective happiness, and it was also objective\u0026nbsp;[18-24]. The SWB was positive with the fractional amplitude of low-frequency fluctuations (fALFF) in the right thalamus, lingual gyrus, posterior mid-cingulate cortex, left postcentral gyrus, planum temporale, and bilateral posterior superior temporal gyrus, which was negative with the left inferior temporal gyrus, right orbitofrontal cortex, and bilateral superior frontal gyrus[18,19]. The SWB was negatively correlated with static functional connectivity between the salience network (SN) and the anterior default mode network (DMN), which was also negatively correlated with the fraction of time that participants spent in a brain state characterized by strong within the DMN and the frontal-parietal network dynamic functional network connectivity (dFNC) [20]. Furthermore, more evidence showed that the SWB was associated with the caudate nucleus [21], and a congenital corpus callosum disorder was associated with decreased SWB [22]. The rating scores of SWB can be predicted by the volume of the left caudate nucleus by promotion focus orientation [24].\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eExploring the effect degree of SWB on FD patients\u0026rsquo; QoL\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003eCurrently, there is a lack of specific management to cure FD patients, of which recurrent episodes may significantly compromise their QoL [5,17]. SWB is also objective, which has a strongly increased risk of moderate/severe depression in long follow-up studies [14,15].\u0026nbsp;Depression may be the cause of FD.SWB influenced QoL in previous studies.

Educational levels were distributed as follows: 5.1% (18/352) illiterate/below primary school, 23.6% (83/352) primary school, 40.3% (142/352) middle school, 14.5% (51/352) high school/technical school, and 16.5% (58/352) college or above. Anxiety levels were categorized as follows: no anxiety in 52.2% (184/352) cases, mild anxiety (\u0026ge;4) in 40.9% (144/352) cases, and moderate/severe anxiety (\u0026ge;10) in 6.8% (24/352) cases. In 352 cases, 45.5% (160/352) cases showed no depression, 44.3% (156/352) cases scoring 4 or above indicative of mild depression, and 10.2%(36/352)cases scoring 10 or above suggestive of moderate to severe depression. Among these, there were 57 cases with PDS, 122 cases with EPS, and 173 cases in the overlap group.

This study represents the first exploration of the effects of SWB on anxiety, depression, symptom severity, and QoL in FD patients.\u003c/p\u003e \u003cp\u003eOur findings indicate that SWB is negatively correlated with anxiety, depression, and symptom severity, which is positively associated with QoL, patients with more severe anxiety and depression symptoms tend to have lower life satisfaction and emotional balance, and dissatisfaction with current life is common among patients with anxiety and depression, leading to reduced life satisfaction, which was following the results in other diseases [\u003cspan citationid=\"CR33\" class=\"CitationRef\"\u003e33\u003c/span\u003e, \u003cspan citationid=\"CR34\" class=\"CitationRef\"\u003e34\u003c/span\u003e]. This study also revealed no significant differences in SWB among the three subtypes of FD, and anxiety had a more significant impact on SWB compared to depression. Therefore, these results suggested that mitigating anxiety and depression may alleviate symptom severity and enhance QoL.\u003c/p\u003e \u003cp\u003eMultivariate analysis showed that SWB had a less significant impact on symptom severity and QoL compared to anxiety and depression, of which the fit degree of the model R\u003csup\u003e2\u003c/sup\u003e was low in this cross-sectional study, which suggested that the influence of SWB was easily ignored in FD patients. Medical staff often focused on the influence of anxiety and depression while neglecting the role of SWB in FD patients. However, considering the brain-gut interaction, anxiety and depression are increasingly recognized as contributing factors to the etiology of FD [\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e, \u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e]. There is an inverse relationship between SWB and resilience in depression [\u003cspan citationid=\"CR34\" class=\"CitationRef\"\u003e34\u003c/span\u003e]. Lower life satisfaction was associated with a significantly increased risk (OR\u0026thinsp;=\u0026thinsp;10.4) of moderate/severe depression over a 15-year follow-up of healthy adults [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e]. Given that most FD cases are chronic, SWB can serve as a crucial potential indicator for studying the development and management of FD in future long-term follow-up studies.\u003c/p\u003e \u003cp\u003eThe determinants of SWB were classified into seven major domains: health and functioning, social support, socioeconomic status, demographic characteristics, personality traits, religious and cultural factors, and infrastructure and geography [\u003cspan citationid=\"CR35\" class=\"CitationRef\"\u003e35\u003c/span\u003e, \u003cspan citationid=\"CR36\" class=\"CitationRef\"\u003e36\u003c/span\u003e]. Socioeconomic status was identified as a significant factor influencing SWB [\u003cspan citationid=\"CR37\" class=\"CitationRef\"\u003e37\u003c/span\u003e, \u003cspan citationid=\"CR38\" class=\"CitationRef\"\u003e38\u003c/span\u003e]. With societal economic development, the prevalence of FD has also increased [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e]. Our findings revealed a positive correlation between patient age and life satisfaction with older individuals reporting higher levels of satisfaction, and higher educational level with higher levels of satisfaction. Additionally, social support emerged as a crucial determinant of SWB [\u003cspan citationid=\"CR39\" class=\"CitationRef\"\u003e39\u003c/span\u003e]. However, medical interventions aimed at improving socioeconomic status and social support are limited in their effectiveness; therefore, this study primarily focused on assessing the health and functioning of SWB, including mental health aspects such as anxiety and depression.\u003c/p\u003e \u003cp\u003eTo enhance SWB, psychotherapeutic interventions have demonstrated moderate effects in reducing negative affect and enhancing positive affect among depressed adults [\u003cspan citationid=\"CR40\" class=\"CitationRef\"\u003e40\u003c/span\u003e]. Educational programs and cognitive interventions have been shown to effectively improve SWB and promote resilience in elderly populations, thereby alleviating depressive symptoms [\u003cspan citationid=\"CR41\" class=\"CitationRef\"\u003e41\u003c/span\u003e]. A positive optimistic personality trait can also contribute to higher SWB [\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e, \u003cspan citationid=\"CR38\" class=\"CitationRef\"\u003e38\u003c/span\u003e].

Furthermore, Ludwigs et al. [\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e] demonstrated that both professional psychological training groups and control groups that repeatedly filled out scales of SWB could effectively enhance SWB without any statistically significant differences between them, and simply reinforcing the concept of SWB can lead to improvements. Therefore, strengthening content awareness of SWB is a simple and feasible approach to improving it.\u003c/p\u003e \u003cp\u003eThis study had the following limitations: Firstly, the data were derived from a single center of FD patients in one hospital, which may limit the generalizability of the findings. Secondly, this was a cross-sectional study that showed that SWB was negatively correlated with symptom severity, anxiety, and depression and positively correlated with QoL. However, as a cross-sectional study, it is limited in its ability to infer causality; therefore, a longitudinal cohort study is necessary to confirm whether enhancing SWB can reduce the incidence or severity of FD symptoms in future research. Thirdly, although SWB showed a negative correlation with anxiety, depression, and disease impact on QoL, the correlation coefficient in this study was below 0.7, indicating a weaker association. Fourthly, multiple linear regression analysis revealed that when including anxiety and depression, SWB did not significantly influence symptom severity and QoL, suggesting that SWB played a less significant role compared to anxiety and depression. Gastroenterology medical staff tended to focus more on the effects of anxiety and depression on FD while overlooking the impact of SWB. However, SWB associated with anxiety and depression, which are potentially the etiology of FD, and lower life satisfaction was associated with a significantly increased risk of moderate/severe depression over a long follow-up study [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e]. These results suggested that reinforcing the impact of FD patients' SWB may help reduce symptoms, which requires further confirmation in future long-term studies.\u003c/p\u003e"},{"header":"Conclusions","content":"\u003cp\u003eThe study indicated that FD patients' SWB was negatively correlated with symptom severity, anxiety, and depression, and positively correlated with QoL.

Anxiety and depression are now gradually believed to be the causes of functional dyspepsia (FD). The influence of SWB was ignored in FD patients. To explore the influence of SWB on anxiety, depression, symptom severity and quality of life (QoL) in FD patients.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eMethods \u003c/strong\u003eA total of 374 patients with FD were selected according to Roman IV criteria. Satisfaction with life scale and affect balance scale, Generalized anxiety disorders-7, Patient healthy questionnaire-9, Dyspepsia symptoms severity(DSS)and Nepean dyspepsia index(NDI) were used to assess SWB,anxiety, depression, symptoms severity and QoL, respectively. One-way variance analysis, t-test, Pearson’s correlation and multiple linear regression were used to analyze the results.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eResults \u003c/strong\u003eLife satisfaction and emotional balance of FD patients were negatively correlated with DSS, anxiety, depression, and NDI for QoL(r=-0.148,-0.330,-0.325,-0.195,\u003cem\u003e \u003c/em\u003eall \u003cem\u003eP\u003c/em\u003e\u0026lt;0.01), (r=-0.205,-0.545,-0.550, -0.357, all \u003cem\u003eP\u003c/em\u003e\u0026lt;0.001), respectively. Multiple linear regression showed that life satisfaction and emotional balance were influencing factors of anxiety(β= -0. 143, \u003cem\u003eP\u003c/em\u003e=0.001), (β= -0. 318, \u003cem\u003eP\u003c/em\u003e\u0026lt;0.001), and depression(β=-0. 122, \u003cem\u003eP\u003c/em\u003e=0.003), (β= -0. 287, \u003cem\u003eP\u003c/em\u003e\u0026lt;0.001), respectively. After removing anxiety and depression, life satisfaction and emotional balance were influencing factors of patients' DSS (β= -0.105, \u003cem\u003eP\u003c/em\u003e=0.049), (β= -0.180, \u003cem\u003eP\u003c/em\u003e=0.001), and QoL(β= -0.117, \u003cem\u003eP\u003c/em\u003e=0.023), (β= -0.329,\u003cem\u003eP\u003c/em\u003e\u0026lt;0.001) ,respectively.\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConclusions \u003c/strong\u003eFD patients’ SWB negatively affects their disease severity, anxiety and depression, and positively affects their QoL. These results suggested that further strengthening SWB may help reduce symptom severity and improve the QoL of patients, which needs to be confirmed by future follow-up studies.\u003c/p\u003e","manuscriptTitle":"The influence of subjective well-being on anxiety, depression and quality of life in patients with functional dyspepsia","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-04-28 11:31:07","doi":"10.21203/rs.3.rs-6109334/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2025-05-09T05:21:37+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-05-08T23:47:47+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-05-06T17:00:02+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"16629302501744513619718033520361539329","date":"2025-04-28T20:04:36+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"199753555798519240374137233703749846996","date":"2025-04-26T06:38:42+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"233326403586561159402073893867711236142","date":"2025-04-25T13:48:35+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"68203241171590597391006430423100665047","date":"2025-04-25T08:45:54+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-04-25T08:00:51+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-04-17T06:40:07+00:00","index":"","fulltext":""},{"type":"submitted","content":"BMC Gastroenterology","date":"2025-04-10T13:41:23+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"
