We used multilevel modeling mixed effects logistic regression for the statistical analyses because of its ability to examine contextual effects in cross-sectional data.</p><p><strong>Results: </strong>The results revealed that the residual variation in state-level 8vANC utilization--after accounting for the explanatory variables-attributable to between-state differences went from 46% in the unadjusted model to11% in the final adjusted model. The findings indicated that women in Southern states had the highest odds of 8vANC utilization. We also found that women who self-reported their perception of life satisfaction as 'very happy' (OR: 1.81, 95% C.I: 1.25-2.63, p = 0.002), and 'somewhat happy' (OR: 1.63, 95% C.I: 1.14-2.40, p = 0.012) had the highest odds of 8vANC utilization across states. Conversely, the perception of wife beating justified 'if she goes out without telling husband' had low odds (OR: 0.77, 95% C.I: 0.61-0.97, p = 0.032) on the penetration of the WHO 8vANC policy across states.</p><p><strong>Conclusion: </strong>A greater proportion of the observed differences in 8vANC penetration occurred among women nested within states than between states. Our findings support the need for a revised policy that promotes the integration of routine prenatal mental health screening into the current ANC model.</p><p><strong>Clinical trial number: </strong>Not applicable.</p>","PeriodicalId":9033,"journal":{"name":"BMC Pregnancy and Childbirth","volume":"25 1","pages":"640"},"PeriodicalIF":2.8,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12128282/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144207558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
