Aim: Influence of nutrition in human growth failure, especially stunting, is a well-accepted idea. The present study assesses the influence of nutrition and non-nutritional factors on height growth in a short stature population. Material and methods: The present study was conducted among the children and adolescents of Sikkim, India. The sample size was 538 (boys and girls) of age 2-18 years. The anthropometric indices mid upper arm circumference-forage Z-scores (MUACZ) and BMI-forage Z-scores (BAZ) were utilised as proxy of nutritional status and growth was assessed using height-forage Z-scores (HAZ). Associations were assessed using correlation, St. Nicolas house analysis (SNHA), principal component analysis (PCA) and regression. Results: Nutritional status of the participating children and adolescents as assessed by MUACZ and BAZ were largely normal. Despite variation in HAZ from-4 to +2 there was no influence of the nutritional indices on height. Further, there was clear lack of association between HAZ and socioeconomic variables in the present study. Conclusion: The findings of the present study suggest nutrition is not the primary regulator of human growth. The possible influence of community effects on height is discussed.

The present study assesses the association of different socio-economic variables with children’s BMI-for-age z-scores (BAZ) and influence of children’s height on BAZ, a proxy index of nutritional status. The study was undertaken among 322 girls belonging to the Bengali Hindu Caste Population (BHCP) aged 5–13 years. These girls were the students of two schools located in Siliguri town of West Bengal, India. The prevalence of short stature, underweight and overweight was assessed using the World Health Organization’s ( WHO, 2007 , Growth Reference Data for 5–19 years) references. The statistical analyses used were St. Nicolas House Analysis (SNHA), analysis of variance (ANOVA), linear and logistic regression. The prevalence of underweight, overweight and obesity was 19.3%, 17.8% and 5.9%, respectively. The prevalence of short stature (−2.0 HAZ) was 8.7%. The range of BAZ was from −5.69 to 4.15. The variation of BAZ explained by height-for-age z-scores (HAZ) was 11.4%. The BAZ was observed to be associated with mothers’ occupation as revealed by 2% variation through SNHA analysis. The present study observed the usefulness of SNHA for non-parametric data with unequal sub-sample or categories. However, SNHA was not devised to assess the direction and magnitude of variables of interest. The finding of the present study supports the use of BAZ as a proxy adiposity measure among the overweight/obese populations and populations with normal growth in height. The study further supports the recommendations that mother empowerment can help improve nutritional status of a girl child.
