Extreme levels of underweight and stunting among pre-adolescent children of low socioeconomic class from Madhyamgram and Barasat, West Bengal, India.

A cross-sectional study on 1206 children (788 boys, 618 girls) aged 1-12 years, belonging to low socioeconomic status, of Barasat and Madhyamgram, West Bengal, India, was undertaken to investigate age and sex variations in height and weight. It also evaluated the levels of underweight and stunting among them. Anthropometric measurements included weight and height. Weight-for-age (WA) and height-for-age (HA) <-2 z-scores were used to evaluate underweight (UW) and stunting (ST), respectively, following the National Center for Health Statistics (NCHS) Guidelines. Results showed that boys aged 4 and 11 years were significantly heavier than girls of corresponding ages. Boys aged 7 years were significantly taller than girls of the same age. Significant (p < 0.001) age differences existed in mean weight and height in boys (weight: F = 336.762; height: F = 565.160) as well as girls (weight: F = 275.320; height = 498.715). Results also revealed that the mean z-scores of WA (WAZ) and HA (HAZ) were less than (negative values) those of NCHS for both sexes at all ages. The overall (age combined) rate of UW was 60.4% and 51.3%; while that of ST was 51.7% and 48.4%, in boys and girls, respectively. Based on World Health Organization classification of severity of malnutrition, the prevalence of UW and ST were very high (> or = 30%) in both sexes. In conclusion, this study demonstrated that the prevalence of UW and ST were very high among the subjects. Since the nutritional status of the subjects is not satisfactory, there is need for immediate supplementary nutrition.
