Abstract

Abstract Background Tuberculosis preventive therapy (TPT) is crucial for preventing the progression from TB infection (TBI) to active disease, particularly among vulnerable populations such as indigenous people. Although shorter regimens have improved adherence, evidence from real-world programmatic settings is limited. This study evaluated whether the indigenous race was associated with greater TPT completion in the Brazilian Amazon. Methods We conducted a retrospective cohort study using data from the IL-TB database (2019–2023) in Amazonas, Brazil. Individuals who initiated TPT were stratified by race. The primary outcome was TPT completion. Multivariate logistic regression identified factors associated with completion, adjusting for sociodemographic, clinical, and operational variables. Results Of the 4,887 individuals, 79.6% completed TPT. Completion was higher among Indigenous individuals (90.9%) than among Nonindigenous individuals (79.1%) (p < 0.001). In the adjusted analysis, indigenous race (OR: 2.4; 95% CI: 1.49–4.06), shortened TPT regimens (OR: 2.36; 95% CI: 2.04–2.73), and receiving care in noncapital municipalities (OR: 2.03; 95% CI: 1.49–2.82) were positively associated with completion. Foreign nationality (OR: 0.28; 95% CI: 0.18–0.44) and TPT nonexclusive primary health care services (OR: 0.79; 95% CI: 0.66–0.94) were negatively associated with such outcomes. Among nonindigenous individuals, associations mirrored those in the overall population. Among Indigenous individuals, only a shortened regimen was significantly associated with completion (OR: 5.75; 95% CI: 1.78–23.4). Conclusions Indigenous individuals presented greater TPT completion, particularly when treated with shortened regimens. These findings reinforce the potential of decentralized strategies and the use of shortened regimens to increase the completeness of tuberculosis preventive therapy and provide evidence for overcoming historical and operational barriers at the program level that still prevail and delay the improvement of public policies aimed at achieving global TB elimination goals, especially in high-burden settings, social inequality and the strong presence of vulnerable populations.

Healthcare disparities Primary health care Program evaluation Figures Figure 1 Figure 2 BACKGROUND Approximately 25% of the world's population is thought to be infected with Mycobacterium tuberculosis , and between 5% and 10% of these individuals will progress to active tuberculosis (TB) ( 1 ). In low- and middle-income countries, the risk of TB progression and the overall disease burden are elevated due to poverty-related conditions. This risk is even greater among vulnerable populations such as indigenous people, migrants, persons with HIV (PLHIV), household TB contacts (especially children under 5 years), and individuals receiving immunosuppressive therapy ( 1 – 3 ). Tuberculosis preventive therapy (TPT) is a key strategy for eliminating tuberculosis ( 4 ), particularly among vulnerable groups such as indigenous peoples, PLHIV, and individuals with household exposure to TB ( 5 ). Once active disease has been ruled out, the World Health Organization (WHO) recommends TPT for those at increased risk of developing tuberculosis infection (TBI) ( 1 ). Isoniazid preventive therapy (IPT) for a 6- or 9-month regimen of daily isoniazid (6H/9H) has historically been widely used; however, its effectiveness is often limited by low completion rates and challenges associated with its extended duration ( 6 ). A shorter regimen recommended by the WHO—three months of once-weekly rifapentine plus isoniazid (3HP)—is noninferior to nine months of IPT and has been associated with higher adherence and completion rates ( 7 ). In 2021, Brazil incorporated 3HP into its national TB program as an option for high-risk groups ( 3 ). Although studies have demonstrated the safety, tolerability, and effectiveness of 3HP in clinical trial settings ( 7 – 10 ), evidence of its programmatic impact, particularly among indigenous communities, remains limited. Thus, we evaluated whether the self-declared Indigenous race was associated with a higher probability of completing TPT in Amazonas, Brazil, where shortened regimens such as 3HP and four months of daily rifampicin (4R) have been widely implemented. We also explored the operational characteristics of surveillance and healthcare delivery to understand the impact of tailored interventions in this high TB burden setting. In 2024, Amazonas recorded a TB incidence of 94.7 per 100,000 inhabitants—the highest among Brazilian states—with Manaus leading among state capitals ( 11 ). The state has unique anthropological, social, cultural, epidemiological, and health service organization characteristics ( 12 ). Factors such as poor living conditions, limited healthcare access, malnutrition, and infrastructure deficits – commonly present in the Amazon – are associated globally with higher TB incidence ( 13 ). METHODS Study Design This retrospective cohort study evaluated whether self-declared Indigenous races were associated with greater TPT completion than nonindigenous races were in Amazonas state, Brazil, between 2019 and 2023. We included new TPT cases among Amazonas residents. The exclusion criteria were cases of primary chemoprophylaxis (e.g., newborns cohabiting with a laboratory-confirmed pulmonary or laryngeal TB case) and records lacking information on race or TPT outcome. Data collection and variable definitions Data were extracted in June 2024 from the National Information System for Latent Infection by Mycobacterium tuberculosis (IL-TB), with authorization from the Amazonas Health Surveillance Foundation “Dra. Rosemary Costa Pinto.” In Brazil, racial classification is based on self-identification, reflecting social, cultural, and historical contexts ( 14 , 15 ). According to the 2022 census ( 16 ), 12.5% of the Amazonas population self-identified as indigenous, comprising diverse ethnic groups, including Yanomami, Kayapó, Ticuna, Guarani, Munduruku, and Ashaninka. Some records also include Indigenous groups from neighboring countries, such as the Warao from Venezuela ( 15 ). The group of Indigenous individuals was defined on the basis of the completion of this category in the race/color field of the IL-TB system. In contrast, the group of nonindigenous individuals was composed of individuals categorized as White, Brown, Black, or Yellow. The IL-TB system collects sociodemographic, epidemiological, clinical, and operational variables. It was developed and implemented nationally in 2019 by the Brazilian Ministry of Health to support the surveillance of latent M. tuberculosis infection. The system defines four eligibility categories for TPT based on Tuberculin skin test (TST) or Interferon Gamma Release Assay (IGRA) results: (a) no TST or IGRA performed; (b) TST ≥ 5 mm or IGRA positive; (c) TST ≥ 10 mm or IGRA positive; and (d) TST conversion (≥ 10 mm increase compared to baseline), each with its respective indication for Therapy Preventive Tuberculosis ( 17 ). For analysis, indications for TPT were grouped into three categories: contact with a TB case, person with HIV, and others. The TPT outcome was defined as either complete or incomplete. Completion was assigned to the “complete treatment” category. At the same time, incomplete outcomes included “Suspended due to adverse reactions,” “Active tuberculosis,” “Death,” “Treatment interruption,” “Transferred to another country,” and “Suspended due to clinical conditions.” The IL-TB system also records sociodemographic and epidemiological data (age, sex, race, residence, TB contact history); clinical data (BCG vaccination, chest X-ray, HIV status, antiretroviral therapy [ART], TST, IGRA); and operational characteristics (type of entry, facility location and type, treatment regimen, prescribing professional, number of doses taken, and treatment closure status). On the basis of these variables, additional operational variables were derived: Location of health unit (capital vs. interior, based on municipal codes); Health service type (exclusively primary health care vs. health services with multiple types of care, including TB control program teams); Latent TB infection (TBI) investigation test performed (TST or IGRA); TBI confirmed by test (TST ≥ 5 mm or IGRA positive) and; Shortened TPT regimen (3HP or 4R vs. 6H/9H). All variables and definitions are presented in Supplementary Table 1. Statistical analysis Continuous variables were summarized using medians and interquartile ranges (IQRs). Categorical variables are presented as absolute and relative frequencies. As appropriate, group comparisons by race and TPT completion status were performed via the Mann–Whitney U test or Student’s t test according to the variable distribution. A significance level of p < 0.05 was adopted. Simple and multivariable binomial logistic regression models were used to estimate odds ratios (ORs) with corresponding 95% CIs and p values. Regression models were applied to the entire study population and separately to the Indigenous and Nonindigenous subgroups. Confounding variables such as age, sex, and TPT indications for PLHIV were retained in the multivariable models. Continuous variables with missing data and those indirectly represented by categorical variables (e.g., number of doses vs. treatment regimen) were excluded. The final multivariable model was selected on the basis of the lowest Akaike information criterion (AIC) and evaluation of multicollinearity via the variance inflation factor (VIF). Model adequacy and goodness-of-fit were assessed through multiple diagnostics, including inspection of the sigmoid curve ( Supplementary Fig. 3–5A ), the deviance goodness-of-fit test (based on a chi-square distribution), Pearson’s standardized residuals, the Hosmer–Lemeshow test, and the simulated standard envelope plot ( Supplementary Fig. 3–5B ). These visual assessments are provided in detail in the supplementary material to support the interpretation of model performance. All analyses were conducted via R software (R Development Core Team, 2024). RESULTS Of the 5,341 records identified between 2019 and 2023, 4,887 new cases were included in the study. Among them, 3,892 completed TPT (3,691 nonindigenous vs. 201 indigenous), whereas 995 did not (975 nonindigenous vs. 20 indigenous) ( Fig. 1 ) . Study population characteristics Table 1 summarizes the characteristics of the study population stratified by self-reported race. A greater proportion of males was observed among Indigenous individuals than among Nonindigenous individuals (56.6% vs. 49.5%; p = 0.048). Brazilian nationality was less common among indigenous individuals (89.6% vs. 98.3%; p < 0.001). Additionally, indigenous individuals more often received TPT in health services located in the interior of the state (52.9% vs. 9.4%; p < 0.001).

Nonindigenous individuals were more likely to receive TPT in services with multiple types of care (58.1%), whereas indigenous individuals more frequently received care exclusively through primary health care services (60.6%). Diagnostic tests (TSTs/IGRAs) for TBI were performed more regularly among indigenous individuals than among nonindigenous individuals (97.7% vs. 88.6%; p < 0.001). Indigenous individuals also presented higher rates of TBI confirmation and TB contact history (96.4% vs. 84.9%; p < 0.001 and 88.2% vs. 57.7%; p < 0.001, respectively). The proportion of TPT indications for PLHIV was lower among indigenous individuals (5.9% vs. 27.8%; p < 0.001). TPT completion was more common among Indigenous individuals than among Nonindigenous individuals (91.0% vs. 79.1%; p < 0.001). Table 2 summarizes the characteristics of the study population according to TPT completion and race. The overall completion rate was 79.6%, with indigenous individuals demonstrating a higher completion rate (90.9%) than nonindigenous individuals did (79.1%). Unlike what was observed in the total population and among nonindigenous people, men had a higher proportion of complete TPT among indigenous people (56.7%). Individuals under 18 years of age had slightly higher completion rates (20.8% complete vs. 17.6% incomplete; p = 0.027). Among adults, the highest proportion of TPT completion was observed among nonindigenous individuals (79.2% vs. 78.1% among indigenous individuals).

Abbreviations: PLHIV, person with human immunodeficiency virus; TB, tuberculosis; TBI, tuberculosis infection; + SD, standard deviation; TST, tuberculin skin test; IGRA, interferon gamma release assay. Brazilian nationality predominated across all groups, although the proportion of foreign nationals was greater among individuals who did not complete TPT (3.6% vs. 1.70%; p < 0.001). TB contact was more common among individuals who completed TPT (60.1% vs. 55%; p = 0.003) and among indigenous individuals than among nonindigenous individuals (89.6% vs. 58.5%). With respect to health unit location, individuals who completed TPT were more frequently treated in interior municipalities (12.9% vs. 5.1%; p < 0.001), a pattern also observed among indigenous participants. Among the indigenous individuals who completed TPT, 62.2% received care exclusively for primary health care services, whereas 43.2% of the nonindigenous individuals did. The performance of tests for TBI investigation (TST/IGRA) was high across all groups, with slightly higher proportions among individuals who completed TPT in the general population (89.4%) and among indigenous participants (98.0%). Confirmation of the TBI by test was observed in 86.2% of individuals who completed TPT (p = 0.006) and in 96.5% of Indigenous individuals. TPT indications for PLHIV were reported in 26.3% of the completers in the general population and in 6.5% of the Indigenous individuals. The use of shortened TPT regimens (3HP/4R) was more common among all groups who completed TPT, with a significant difference in the general population (63.3% vs. 43.8%; p < 0.001). Factors associated with TPT completion in the study population According to the adjusted logistic regression model, TPT completion was positively associated with the Indigenous race (OR: 2.4; 95% CI: 1.49–4.06; p < 0.001), treatment in health units located in the interior (OR: 2.03; 95% CI: 1.49–2.82; p < 0.001), and the use of shortened TPT regimens (OR: 2.36; 95% CI: 2.04–2.73; p < 0.001). Conversely, foreign nationality (OR: 0.28; 95% CI: 0.18–0.44; p < 0.001) and receiving care in services with multiple types of care (OR: 0.79; 95% CI: 0.66–0.94; p = 0.008) were associated with lower odds of completing TPT. Additionally, TBI confirmed by TST/IGRA (OR: 1.57; 95% CI: 1.06–2.31; p = 0.022) and TPT indications for PLHIV (OR: 1.31; 95% CI: 1.04–1.65; p = 0.020) were also positively associated with TPT completion ( Fig. 2 ) . When factors associated with TPT completion by subpopulation were analyzed, the adjusted model for indigenous individuals revealed that only the use of the shortened 3HP/4R regimen was significantly associated with completion (OR: 5.75; 95% CI: 1.78–23.4; p = 0.006), as shown in Supplementary Fig. 2 . Among nonindigenous individuals, shortened regimens (OR: 2.31; 95% CI: 1.99–2.68; p < 0.001), TPT performed in interior municipalities (OR: 2.25; 95% CI: 1.61–3.23; p < 0.001), TBI confirmation (OR: 1.58; 95% CI: 1.06–2.32; p = 0.020), and TPT indication for PLHIV (OR: 1.28; 95% CI: 1.02–1.61; p = 0.036) were all positively associated with treatment completion. Conversely, as observed in the total population, among nonindigenous individuals, being a foreign nation (OR: 0.25; 95% CI: 0.16–0.41; p < 0.001) and receiving TPT in services with multiple types of care (OR: 0.8; 95% CI: 0.67–0.96; p = 0.018) were associated with lower odds of completion (Supplementary Fig. 1) . DISCUSSION In Brazil, TPT was not historically prioritized as a central component of TB control. Although incorporated into national guidelines between 2011 and 2018, active case finding remained the primary preventive measure. TPT was mainly recommended for specific groups, such as contacts of laboratory-confirmed pulmonary TB cases, PLHIV, and individuals in areas with better TB indicators and lower treatment interruption rate ( 18 ). Until the first half of 2021, the primary regimen available for TPT in Brazil was Isoniazid monotherapy (6H or 9H). Although 4R (four months of daily rifampicin) was also available, its use remained limited to specific populations ( 19 ). Following the incorporation of 3HP into the public health system in the second half of 2021, this regimen progressively replaced Isoniazid monotherapy and, by the end of 2023, accounted for approximately 50% of TPT initiations nationally. In Amazonas, however, uptake was faster, with 3HP representing around 90% of all TPT initiations ( 11 ). The rapid implementation of 3HP contributed to its consolidation as the preferred regimen in the Amazonas, a region marked by both high TB burden and the largest Indigenous population in the country, most of whom reside in municipalities located in the interior ( 16 ). This study provides important insights into TPT outcomes in the Brazilian Amazon, revealing high overall completion rates and significantly better adherence among indigenous individuals. These findings challenge the prevailing assumption that indigenous populations consistently experience poorer outcomes due to social vulnerability ( 20 ). Instead, our data suggest that targeted strategies—such as shorter regimens and decentralized care delivery—may have played a pivotal role in improving adherence in these communities. The strong association between shortened TPT regimens and completion, particularly among indigenous individuals, reinforces the importance of treatment simplification in enhancing adherence. In our stratified analysis, the use of a short regimen was the only factor significantly associated with completion in the Indigenous subgroup. This aligns with previous literature demonstrating that strong social cohesion and community engagement—often observed in indigenous populations—facilitate adherence, especially when culturally adapted interventions and trusted local leaders are involved ( 21 , 22 ). Extensive global evidence also highlights the disproportionate burden of TB among indigenous peoples and the need for tailored approaches to improve access and outcomes ( 23 – 28 ). Our findings contribute real-world programmatic evidence supporting this approach in a high-burden region. The positive association between TPT completion and care provided in interior municipalities highlights the potential impact of health system decentralization. Recent efforts to expand service delivery beyond capital cities may improve access and program effectiveness, particularly with community-based strategies ( 29 ). Additionally, TPT completion was greater in services operating exclusively through primary health care (PHC), supporting models emphasizing accessibility, continuity of care, and trust between providers and patients ( 30 ). Conversely, foreign nationality was associated with lower odds of TPT completion, underscoring well-documented barriers faced by migrants and nonnationals, such as limited knowledge about latent TB, stigma, and restricted access to care. Evidence from other high-burden countries suggests that foreign-born individuals may benefit from intensified support strategies, including culturally adapted counseling and directly observed therapy ( 31 ). These results emphasize the need for inclusive policies and health services tailored to all vulnerable groups’ linguistic and cultural needs. This study has several limitations. Using secondary data from a programmatic database may involve information bias, including incomplete or inaccurate outcome reporting. Health workers self-identify or classify races, which may not fully capture their sociocultural identity. However, the maintenance of key covariates and the selection of our model on the basis of careful assumptions of fit and adequacy sought to minimize confounding and emphasize the representativeness of the population of our study in the Brazilian Amazon scenario. Despite these limitations, our findings offer robust real-world evidence that simplified TPT regimens, combined with decentralized and primary healthcare–based delivery models, can substantially improve treatment completion in high-burden and underserved settings. Indigenous individuals’ notably high completion rates demonstrate that equity-focused and culturally sensitive interventions can overcome historical barriers and deliver successful TB prevention outcomes. Scaling up access to short-course regimens and strengthening local health systems are critical next steps to advance TB elimination in the Amazon and similar contexts. CONCLUSIONS Our findings offer robust real-world evidence that simplified TPT regimens, combined with decentralized and primary healthcare–based delivery models, can substantially improve treatment completion in high-burden and underserved settings. Indigenous individuals’ notably high completion rates demonstrate that equity-focused and culturally sensitive interventions can overcome historical barriers and deliver successful TB prevention outcomes.

Although incorporated into national guidelines between 2011 and 2018, active case finding remained the primary preventive measure. TPT was mainly recommended for specific groups, such as contacts of laboratory-confirmed pulmonary TB cases, PLHIV, and individuals in areas with better TB indicators and lower treatment interruption rate (\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eUntil the first half of 2021, the primary regimen available for TPT in Brazil was Isoniazid monotherapy (6H or 9H). Although 4R (four months of daily rifampicin) was also available, its use remained limited to specific populations (\u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e). Following the incorporation of 3HP into the public health system in the second half of 2021, this regimen progressively replaced Isoniazid monotherapy and, by the end of 2023, accounted for approximately 50% of TPT initiations nationally. In Amazonas, however, uptake was faster, with 3HP representing around 90% of all TPT initiations (\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eThe rapid implementation of 3HP contributed to its consolidation as the preferred regimen in the Amazonas, a region marked by both high TB burden and the largest Indigenous population in the country, most of whom reside in municipalities located in the interior (\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eThis study provides important insights into TPT outcomes in the Brazilian Amazon, revealing high overall completion rates and significantly better adherence among indigenous individuals. These findings challenge the prevailing assumption that indigenous populations consistently experience poorer outcomes due to social vulnerability (\u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e). Instead, our data suggest that targeted strategies\u0026mdash;such as shorter regimens and decentralized care delivery\u0026mdash;may have played a pivotal role in improving adherence in these communities.\u003c/p\u003e \u003cp\u003eThe strong association between shortened TPT regimens and completion, particularly among indigenous individuals, reinforces the importance of treatment simplification in enhancing adherence. In our stratified analysis, the use of a short regimen was the only factor significantly associated with completion in the Indigenous subgroup. This aligns with previous literature demonstrating that strong social cohesion and community engagement\u0026mdash;often observed in indigenous populations\u0026mdash;facilitate adherence, especially when culturally adapted interventions and trusted local leaders are involved (\u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e, \u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e22\u003c/span\u003e).\u003c/p\u003e \u003cp\u003eExtensive global evidence also highlights the disproportionate burden of TB among indigenous peoples and the need for tailored approaches to improve access and outcomes (\u003cspan additionalcitationids=\"CR24 CR25 CR26 CR27\" citationid=\"CR23\" class=\"CitationRef\"\u003e23\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR28\" class=\"CitationRef\"\u003e28\u003c/span\u003e).

Although shorter regimens have improved adherence, evidence from real-world programmatic settings is limited. This study evaluated whether the indigenous race was associated with greater TPT completion in the Brazilian Amazon.\u003c/p\u003e\u003ch2\u003eMethods\u003c/h2\u003e \u003cp\u003eWe conducted a retrospective cohort study using data from the IL-TB database (2019\u0026ndash;2023) in Amazonas, Brazil. Individuals who initiated TPT were stratified by race. The primary outcome was TPT completion. Multivariate logistic regression identified factors associated with completion, adjusting for sociodemographic, clinical, and operational variables.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e \u003cp\u003eOf the 4,887 individuals, 79.6% completed TPT. Completion was higher among Indigenous individuals (90.9%) than among Nonindigenous individuals (79.1%) (p\u0026thinsp;\u0026lt;\u0026thinsp;0.001). In the adjusted analysis, indigenous race (OR: 2.4; 95% CI: 1.49\u0026ndash;4.06), shortened TPT regimens (OR: 2.36; 95% CI: 2.04\u0026ndash;2.73), and receiving care in noncapital municipalities (OR: 2.03; 95% CI: 1.49\u0026ndash;2.82) were positively associated with completion. Foreign nationality (OR: 0.28; 95% CI: 0.18\u0026ndash;0.44) and TPT nonexclusive primary health care services (OR: 0.79; 95% CI: 0.66\u0026ndash;0.94) were negatively associated with such outcomes. Among nonindigenous individuals, associations mirrored those in the overall population. Among Indigenous individuals, only a shortened regimen was significantly associated with completion (OR: 5.75; 95% CI: 1.78\u0026ndash;23.4).\u003c/p\u003e\u003ch2\u003eConclusions\u003c/h2\u003e \u003cp\u003eIndigenous individuals presented greater TPT completion, particularly when treated with shortened regimens. These findings reinforce the potential of decentralized strategies and the use of shortened regimens to increase the completeness of tuberculosis preventive therapy and provide evidence for overcoming historical and operational barriers at the program level that still prevail and delay the improvement of public policies aimed at achieving global TB elimination goals, especially in high-burden settings, social inequality and the strong presence of vulnerable populations.\u003c/p\u003e","manuscriptTitle":"Completeness of preventive therapy for tuberculosis in indigenous versus nonindigenous populations in the Brazilian Amazon: a retrospective cohort study","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-06-11 08:32:34","doi":"10.21203/rs.3.rs-6811654/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2025-07-15T04:40:47+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-07-11T18:29:15+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-07-10T09:53:48+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-07-09T09:34:15+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-07-07T20:31:06+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-07-03T14:37:21+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"269140807580029900729758364057748780132","date":"2025-06-28T11:26:35+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"38362151704560614865300366695625028944","date":"2025-06-26T11:51:28+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"15592253371988184128949806348542948424","date":"2025-06-25T12:54:14+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-06-25T04:56:55+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"149094225292698733607550827641742188684","date":"2025-06-24T17:16:11+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"202305709686242178858270943595152121588","date":"2025-06-24T14:37:29+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"151229803065805236084886170762348764328","date":"2025-06-24T12:54:57+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"32681936559947738721105242008728244747","date":"2025-06-24T09:44:34+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"54986792824337898622919645576256248806","date":"2025-06-20T14:53:18+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-06-19T14:22:26+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"","date":"2025-06-10T05:23:47+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-06-10T00:15:07+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-06-10T00:14:17+00:00","index":"","fulltext":""},{"type":"submitted","content":"BMC Public Health","date":"2025-06-03T12:58:55+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"bmc-public-health","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"pubh","sideBox":"Learn more about [BMC Public Health](http://bmcpublichealth.biomedcentral.com/)","snPcode":"","submissionUrl":"https://www.editorialmanager.com/pubh/default.aspx","title":"BMC Public Health","twitterHandle":"@BMC_series","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"em","reportingPortfolio":"BMC Series","inReviewEnabled":true,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"2bca87fe-e3f7-4713-9670-56d2d72390f1","owner":[],"postedDate":"June 11th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"published-in-journal","subjectAreas":[],"tags":[],"updatedAt":"2025-12-10T15:31:52+00:00","versionOfRecord":{"articleIdentity":"rs-6811654","link":"https://doi.org/10.1186/s12889-025-25177-8","journal":{"identity":"bmc-public-health","isVorOnly":false,"title":"BMC Public Health"},"publishedOn":"2025-12-02 15:58:13","publishedOnDateReadable":"December 2nd, 2025"},"versionCreatedAt":"2025-06-11 08:32:34","video":"","vorDoi":"10.1186/s12889-025-25177-8","vorDoiUrl":"https://doi.org/10.1186/s12889-025-25177-8","workflowStages":[]},"version":"v1","identity":"rs-6811654","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-6811654","identity":"rs-6811654","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
