RESUMO
Background: As undernutrition and anemia persist to be prevalent in India, the socioeconomically disadvantaged groups continue to take the greater brunt. Odisha is home to the largest number of particularly vulnerable tribal groups (PVTGs) in India. The study aimed to provide a comprehensive report on the undernutrition and anemia status of all the PVTGs of Odisha. Methods: A community-based cross-sectional study was conducted among (N = 1461, 683 males and 779 females) 13 PVTGs spread across 12 districts of Odisha from August 2018 to February 2019. Results: Among the under-five children, the prevalence of underweight was observed in 75.26%, stunting in 55.42%, and wasting in 60.00% and all forms of undernutrition were higher among girls. Among children and adolescents belonging to the age group of 5 to 19 years, the prevalence of thinness was 46.7%. In individuals above the age of 20, the prevalence of underweight among males was 37.7% and females was 44.3% and severe anemia was present in 36.5% of females and 35.8% of males. Women in the reproductive age have a higher prevalence of anemia. Conclusion: The study shows that undernutrition and anemia remain high in the PVTGs, especially among the under-five children and women in the reproductive age. As the country heads toward fulfilling Sustainable Development Goals (SDG) by 2030, national and state health policies need to be designed and implemented, giving special focus to these vulnerable groups.
RESUMO
OBJECTIVE: The current study aimed to estimate prevalence of malaria infection, especially sub-patent infection, in pregnant women residing in high malaria-endemic, hard-to-reach pockets of the Indian state of Odisha; and also measure its impact on birth-weight of their new-borns. METHOD: A time-to-event analysis of prospective longitudinal follow-up study nested within a cross-sectional survey of people residing in high malaria-endemic six districts of Odisha was conducted during July-November 2019. Malaria status in pregnant mothers was categorized as malaria free; sub-patent, and patent. Hazards Ratio (HR) of low birth-weight (LBW; birth-weight < 2500 gms) was estimated in these three categories (n = 308) adjusted for residence (block), gravida, caste, age and gestational age at testing. RESULTS: 50.3% pregnant women had sub-patent malaria infection, 3.9% had patent infection. In fully adjusted model, hazards ratio of LBW was 3.76 (95% CI 1.12, 12.64, p = 0.032) in pregnant women with patent infection and 1.82 (95% CI 0.87, 3.81, p = 0.109) in women with sub-patent infection when compared to no malaria group. CONCLUSION: The study showed that half of the pregnant women in high-endemic pockets had sub-patent infection which posed deleterious influence on birth-weight of their new-borns. The study thereby flags the prevalence of sub-patent infection as a public health concern, because sub-patent infection in pregnant mothers may persist as a "silent" reservoir, with the potential to derail the malaria control program, especially when the country plans malaria elimination by 2030.
