Beyond prevalence, it seeks to address the etiological contribution of iron and other erythropoietic micronutrient deficiencies and to evaluate the effectiveness of anemia prevention and treatment interventions, including factors associated with non-response. This will directly support India\u2019s \u201ctest\u2013treat\u2013track\u201d approach under the Anemia Mukt Bharat program.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Participants<\/jats:title>\n                    <jats:p>Children (0\u201318\u202fyears), pregnant women, and NPNL women in India.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Findings to date<\/jats:title>\n                    <jats:p>The database currently includes 88 datasets (1994\u20132023), with 319,721 participants for prevalence analysis\u2014children (19,762), NPNL women (17,883), and pregnant women (282,076). Intervention studies comprise 59,292 participants\u2014children (13,435), NPNL women (11,594), and pregnant women (34,263). Over half the datasets (55.7%, 49\/88) are randomized controlled trials, while 35.2% (31\/88) are observational. Geographically, 43.2% (38\/88) are from northern India, 22.7% (20\/88) from the west, and 18.2% (16\/88) from the south. Most studies (67%, 59\/88) are community-based. Median ages were 26\u202fyears (IQR 23\u201332) for NPNL and 23\u202fyears (IQR 21\u201325) for pregnant women, while children\u2019s data covered 6\u202fmonths to 18\u202fyears. Mean gestational age at enrollment in pregnancy was 10.24\u202fweeks (SD 17.65). Of the total sample, 10.8% had complete blood count data, 9% ferritin, and 4.5% vitamin B12.<\/jats:p>\n                    <jats:p>Among interventions, pregnant women received intravenous iron sucrose, ferric carboxymaltose, iron isomaltoside, combined IV iron with vitamin B12\/folic acid\/niacinamide, integrated packages, and low-dose calcium supplementation. NPNL women were often part of trials comparing 60\u202fmg daily ferrous sulfate with 120\u202fmg on alternate days. Children\u2019s interventions mainly included ferrous sulfate, food supplementation, and select Ayush-based approaches.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Future plans<\/jats:title>\n                    <jats:p>PRAYAS will generate robust, policy-relevant evidence to refine anemia prevention and treatment strategies.
