RESUMEN
BACKGROUND: International studies of the health of Indigenous and tribal peoples provide important public health insights. Reliable data are required for the development of policy and health services. Previous studies document poorer outcomes for Indigenous peoples compared with benchmark populations, but have been restricted in their coverage of countries or the range of health indicators. Our objective is to describe the health and social status of Indigenous and tribal peoples relative to benchmark populations from a sample of countries. METHODS: Collaborators with expertise in Indigenous health data systems were identified for each country. Data were obtained for population, life expectancy at birth, infant mortality, low and high birthweight, maternal mortality, nutritional status, educational attainment, and economic status. Data sources consisted of governmental data, data from non-governmental organisations such as UNICEF, and other research. Absolute and relative differences were calculated. FINDINGS: Our data (23 countries, 28 populations) provide evidence of poorer health and social outcomes for Indigenous peoples than for non-Indigenous populations. However, this is not uniformly the case, and the size of the rate difference varies. We document poorer outcomes for Indigenous populations for: life expectancy at birth for 16 of 18 populations with a difference greater than 1 year in 15 populations; infant mortality rate for 18 of 19 populations with a rate difference greater than one per 1000 livebirths in 16 populations; maternal mortality in ten populations; low birthweight with the rate difference greater than 2% in three populations; high birthweight with the rate difference greater than 2% in one population; child malnutrition for ten of 16 populations with a difference greater than 10% in five populations; child obesity for eight of 12 populations with a difference greater than 5% in four populations; adult obesity for seven of 13 populations with a difference greater than 10% in four populations; educational attainment for 26 of 27 populations with a difference greater than 1% in 24 populations; and economic status for 15 of 18 populations with a difference greater than 1% in 14 populations. INTERPRETATION: We systematically collated data across a broader sample of countries and indicators than done in previous studies. Taking into account the UN Sustainable Development Goals, we recommend that national governments develop targeted policy responses to Indigenous health, improving access to health services, and Indigenous data within national surveillance systems.

BACKGROUND: Multiple micronutrient deficiencies continue to be a major nutritional problem of public health significance in India. AIM: To assess the prevalence of micronutrient deficiencies among rural children of West Bengal, India. SUBJECTS AND METHODS: A community-based cross-sectional study was carried out on 9228 and 437 pre-school children, respectively, for assessment of vitamin A deficiency (VAD) and anaemia. Iodine deficiency disorders (IDD) were assessed in 3490 children of 6-12 years. RESULTS: The prevalence of Bitot's spots, an objective sign of clinical VAD, was 0.6% and was significantly (p < 0.01) higher among children of 3-5 years. Prevalence of blood vitamin A deficiency ( < 20 µg/dL) was 61% and â¼81% of children were anaemic. About 25% children had both sub-clinical VAD and anaemia. The children of Scheduled Caste and Scheduled Tribe (OR = 2.3: 95% CI = 1.3-3.9) were at higher risk of anaemia, whereas children of Scheduled Tribe (OR = 4.5; 95% CI = 2.1-10.5) and 3-5 years (OR = 1.4; 95% CI = 1.0-2.0) were at risk for VAD. The prevalence of goitre was 9%. CONCLUSIONS: Micronutrient deficiencies were found to be of public health significance among rural children of West Bengal. Therefore, there is a need to initiate sustainable long-term interventions for prevention and control of micronutrient deficiencies in children.
