Effect of caste on health, independent of economic disparity: evidence from school children of two rural districts of India.

Caste, a stratifying axis of the Indian society, is associated with wealth and health. However, to what extent caste-based health inequality is explained by wealth disparities, is not clear. Therefore, we aimed to examine the caste-based differences in anaemia (haemoglobin < 11 gm/dl) and self-reported sickness absenteeism in schoolchildren and the mediating role of economic disparity. Students (n = 1764) were surveyed from 54 government schools of Dhenkanal and Angul, Odisha state. Socioeconomic data, anaemia and absenteeism were recorded. The relative risks of anaemia among Scheduled Tribe (least advantaged) and Scheduled Caste (second least advantaged) students were 1.19 (95% CI: 1.08, 1.26) and 1.13 (1.03, 1.20), respectively, as compared to students of the most advantaged caste and that for sickness absenteeism were 2.78 (2.03, 3.82) and 2.84 (2.13, 3.78); p < 0.05, with marginal attenuation when controlled for inter-caste economic disparities. Caste had an independent effect on anaemia and sickness absenteeism in school children, unexplained by inter-caste economic disparities.

Effectiveness of Fortified Mid-Day Meal in Reducing Anemia Among School Children in Dhenkanal, Odisha: A Quasi-Experimental Study.

BACKGROUND: Iron-deficiency anemia among school-aged children is widespread in India. The efficacy of micronutrient and iron fortified school-served meals in reducing iron deficiency anemia has been demonstrated in randomized controlled trials in other parts of the globe. The current study evaluates its effectiveness in real-world Indian settings. METHODS: Mid-day-Meal (MDM) programme provides free lunch to students of grades 1 to 8 in all public-funded Indian schools. An implementation research project fortified MDM of all public schools of 4 out of 8 sub-districts ("blocks") of Dhenkanal district of Odisha state with fortified rice kernel (FRK). All the schools of the other 4 blocks fortified with micronutrient powders (MNP)-both FRK and MNP containing equal amounts of supplementary iron and other micronutrients. Schools of 4 matched blocks of neighboring nonimplementing Angul district served as control. Cross-sectional representative samples of students were drawn from the 3 arms, before and after intervention (n = 1764 and n = 1640 respectively). Pre-post changes in anemia prevalence and hemoglobin levels were estimated in the sampled children using difference-in-difference analysis after controlling for inter-arm differences in socioeconomic status, and iron and deworming tablet consumptions. RESULTS: Factoring in pre-post changes in control and adjusting for potential confounders, the proportion of children without anemia and mean hemoglobin improved by 1.93 (1.38, 2.24, P < .001) times and 0.24 (-0.03, 0.51, P = .083) g/dL in MNP; and 1.63 (1.18, 2.24, P = .002) times and 0.18 (-0.09, 0.45, P = .198) g/dL in FRK arms. CONCLUSIONS: Fortified MDM could effectively improve anemia status among Indian school-aged children under real-world conditions.
