Effect of germination of finger millet on nutritional value of foods and effect of food supplement on nutrition and anaemia status in Tanzanian children.

Inadequate dietary intake, often combined with an infection can lead to malnutrition that often manifest as growth failure or deficiency of essentials nutrients including iron leading to iron deficiency anaemia. In an effort to investigate diet in relation to nutrition status of children, diet and dietary intake were investigated in rural Tanzania. The effect of germination of finger millet based food recipe on its nutritional value was evaluated. The food consisted of finger millet flour, kidney beans, ground peanuts and dried mangoes at predetermined proportions of 75:10:10:5 respectively. Dietary habits of young children were investigated and effects of a fortified food supplement and the cereal based recipe on nutrition status of children were investigated. The two diets were then supplemented to children for 6 months and changes on anaemia and anthropometrical indices of children were evaluated at follow up periods. To assess anaemia and iron status, haemoglobin (Hb), haematocrit (Hct), erythrocyte protoporphyrin (EP) and serum ferritin (SF); and weights and heights were measured to assess growth. A significant improvement in nutrient density was noted in processed cereals. Bioavailability of iron in cereal based diet increased from 0.75 +/- 18 to 1.25 +/- 41 mg/100 g (P = 008), viscosity was significantly raised by 12% and phytate concentration was reduced from 4.5 +/- 0.5 to 4.1 +/- 0.5 mg/g (P = 0.03). Significantly lower intake of iron was observed in schoolchildren with Hb < 11.5 g/dl) compared to those who were normal. Total iron intake was 22+/- 7 and 27 +/- 13 mg/day, respectively (P < 0.05). There was a significant correlation between iron intake and serum ferritin (r = 0.233, P < 0.05). After six months of supplementing children with the fortified beverage a significantly larger increase in haemoglobin concentration was shown in the fortified group than in the non-fortified group (a difference of 6.2 versus 3.2 g/dl respectively). Supplementing infants with the germinated cereal based food supplement showed a general improvement on Hb status and growth that was not significantly different to that in the control group (P > 0.05). In conclusion, consumption of foods with low iron bioavailability is a major cause of anaemia. Germination improves the nutritional value of foods however there is need to fortify such processed foods for infant feeding.

Nutritional status of underfive children in a pastoral community in Simanjiro district, Tanzania.

A study was conducted in Simanjiro district in northern Tanzania to determine the nutritional status of underfive children in a pastoral community. Weight and height measurements were carried out on 250 children and that of mean upper arm circumference (MUAC) on 226 children. The z-scores of weight-for-age, weight-for-height and height-for-age indicated that 31.2% of the children were underweight and 6.0% were severely underweight. Wasting was observed in 17.2% children of whom 3.2% were severely wasted. Severely stunted children were 3.2% while 14% were moderately stunted. Measurements of MUAC indicated that 35% and 3.5% of the children were moderately and severely undernourished, respectively. The nutritional status of the children under study was slightly lower than the national average. In conclusion, malnutrition in Simanjiro district is prevalent, and therefore, appropriate multidisciplinary approach on nutrition education, environmental sanitation and hygienic practices at family and community level need to be promoted to reduce childhood illnesses thereby increasing child health and nutritional status.

Nutritional status and feeding practices of under-five children in Simanjiro District, Tanzania.

This study was undertaken to assess the nutritional status and feeding practices of < 5 year children among the pastoral communities of Simanjiro district, northern Tanzania. Face-to-face interviews with the sampled mothers were conducted using a semi-structured questionnaire. Anthropometric measurements using weight-for-age criterion were employed to assess the nutritional status. The study showed that 31% of the children were undernourished, some (6%) of them severely. Children 2 - 3 years old were the most affected. Breastfeeding duration of more than one year was common among the mothers. Fifty-four percent of the mothers weaned their children as early as two months after birth. The most common type of weaning food was maize porridge (gruel) mixed with cow's milk (46%). Generally, 87% of households were facing some degree of food insecurity where some of them either experienced food shortage for 3-4 months (40%) or reported to eat less than three meals per day (75%). An educated mother was less likely to have an undernourished child, while a child from a teenage mother was more likely to be undernourished. Small size of a household was in favour of nutrition status. There is a great need to undertake interventions through community education to rescue the situation in Simanjiro district. Efforts should also be undertaken to mobilize the community members to adopt practices that favour good nutrition of children.
