Iron nutritional status of adolescent girls from rural area and urban slum.

Iron nutritional status of adolescent girls belonging to an urban slum and rural areas was assessed by measuring serum ferritin levels. Overall anemia was observed in 25% of the girls irrespective of their urban rural residence. A higher percentage of rural girls (37.5%) especially below the age of 12 years showed evidence of anemia. Thereafter, the prevalence was similar in both urban and rural girls who had not attained menarche. With increasing age, urban girls who had attained menarche showed an increase in the prevalence of anemia. The prevalence of iron deficiency (serum ferritin < 12 micrograms/dl) showed a progressive increase from 60% at < 12 to 28% at > 14 yrs especially in the girls not attained menarche in the girls not attained menarche in the rural area. Overall iron deficiency was of much higher order in the rural girls irrespective of the menarcheal status. Distribution of iron/folate tablets to cover girl population may go a long way to correct the anemia and iron deficiency in the vulnerable groups.

Plasma ferritin in the assessment of iron status of Indian infants.

In order to assess the iron nutritional status of infants, plasma ferritin levels were measured in the infants and children at different time intervals till two years of age from two different socio economic groups. While ferritin levels at 3-4 months age were significantly higher in upper income group infants, levels were almost similar in the subsequent infancy between the two income groups. A close correlation was seen between ferritin levels of mothers and infants at 1-3 months of age (p less than 0.001). Prenatal iron supplements (oral or parenteral) resulted in higher ferritin levels at 4-6 months age as compared to placebo group. While the infants born to mothers receiving parenteral iron did not show any evidence of iron deficiency (serum ferritin levels less than 12 ng/ml), 23.5 and 25.0% of infants in oral iron and placebo group had evidence of iron deficiency between 6-12 months. Thus it would appear that improving the iron status of mothers during pregnancy will have significant impact on the iron status of breast fed infants till 6 months.

Use of body mass index for assessing the growth status of infants.

Growth status of infants measured by weight and height was assessed from birth to 12 months in a randomly selected community from the urban slums of Hyderabad City. Mean birth weight was 2.82 kg. Weight/height indicator of body mass index (BMI) showed a progressive increase till 4th month, followed by more or less a constant figure with a mean value of 1.50 in longitudinal, semi-longitudinal and cross sectional data till one year. Critical limit for BMI at birth for given weight of 2.5 kg was 1.20 and subsequently increased to 1.35. BMI was well correlated with weight and weight for height (%) and least correlated with height. Children with height of 90% or above and birth weight of above 2.5 kg were observed with better growth and better maintenance of weight for height (%) and BMI till 6 months.
