    (2023) BARUAH, URMIMALA; Bhattacharyya, Ruma
    The present investigation was undertaken to assess the nutritional status of the Bodo tribes of Assam with the objectives to assess the socio-demographic profile and the nutritional status of the study population in terms of anthropometric indices, food consumption pattern, clinical and biochemical parameters along with the traditional/etnic food processing and preservation practices of the target population. Three hundred eighty eight households were selected by multistage proportionate probability sampling from four districts of Assam, namely- Baksa, Chirang, Kokrajhar and Udalguri. Food consumption pattern of the population revealed that four meals a day was practiced which mainly comprises of the traditional food items prepared from rice, meat, dry fish, pulses. The frequency of consumption of food groups by the Bodo households revealed that cent per cent of the respondents consumed cereals, other vegetables, fats and oils and sugar and jaggery on a daily basis. The mean value for household dietary diversity is 6 which indicate on an average the Bodo households consumed ≤7 food groups out of 12 food groups over the preceeding 24-hour. This indicates inadequate dietary diversity of the Bodo households. The percentage distribution revealed that 56 per cent of the Bodo households had inadequate household dietary diversity and 44 per cent of the Bodo households had adequate household dietary diversity. The household food security status of the Bodo households revealed that 62.27% were food secure, 27.73% were mildly food insecure, 7% were moderately food insecure and 3% were severely food insecure. Food intake pattern as analyzed in terms of Balanced Diet recommended, it was found that the mean daily intake of cereals among 4-6 years was (93.36-95.44%) of the BDR. The average daily intake of pulses was 71.93%-74.40% of the BDR. The mean daily intake of meat, fish and poultry 84.32%-86.96% of the BDR. It was noteworthy to mention that the mean daily intake of milk and milk products, fruits and green leafy vegetables by 4-6 years boys and girls was 30.85%-36.52%, 39.22%-42.20% and 60.32%-64.12% respectively which was much lower than the BDR. The mean daily intake of cereals was 115.43% of the BDR among 13-15 year adolescent girls. The mean daily intake of pulses among 13-15 adolescent girls was 73.70% of the BDR. The mean daily intake of meat, fish and poultry among 13-15 years adolescent girls was 85.52% of the BDR. The mean daily intake of milk and milk products, fruits and green leafy vegetables was 33.05%, 43.06%, 60.66% respectively among 13-15 years adolescent girls. Mean daily intake of cereals by the 16-18 year adolescent girls was 131.61% of the BDR. The mean daily intake of milk and milk products, fruits and green leafy vegetables among 16-18 year adolescent girls was 18.02%, 38.46%, 66.16% of the BDR respectively. The mean daily intake of meat fish and poultry among 16-18 year adolescent girls was 88.96% of the BDR. The mean daily intake of cereals among the pregnant women and lactating women was 167.48% and 125.05% of the BDR respectively. It was found that the mean daily intake of milk and milk products, green leafy vegetables and fruits among the pregnant women was 17.74%, 65.68% and 35.13% of the BDR respectively. The mean daily intake of milk and milk products, green leafy vegetables and fruits among the lactating women was 20.28%, 39.66% and 64.34% of the BDR respectively. While analyzing the mean daily nutrient intake of 4-6 years boys and girls, it was found that the mean daily intake of energy, protein, carbohydrate and fat was 87.51%, 91.40%, 178.53% and 87.36% of the EAR respectively among 4-6 years boys. The average daily intake of iron, calcium, vitamin A and vitamin C was 73.25%, 76.88%, 62.16% and 70.48 % of the EAR respectively by 4-6 year boys. The mean daily intake of energy, protein, carbohydrate and fat was 83.83%, 93.35%, 183.42%, 87.36% of the EAR respectively among the 4-6 year girls. The average daily intake of iron, calcium, vitamin A and vitamin C was 77.62%, 75.40%, 75.26% and 74.14% of the EAR among the 4-6 years girls.
