Abstract

The aim of the present study was to analyse the changes in body composition of stunted children during a follow-up period and to test the hypothesis of a tendency to accumulate body fat as a consequence of undernutrition early in life. We selected fifty boys and girls aged 11 to 15, who were residents of slums in Sao Paulo, Brazil. Twenty were stunted (S) and thirty had normal stature (NS). The children's nutritional status and body composition were assessed through anthropometry and dual-energy X-ray absorptiometry, at the beginning of the present study and after 3 years, and changes in lean mass (LM and LM%) and fat mass (FM and FM%) were calculated. Stunted boys accumulated more body fat (FM%: S=1.62%, NS=-3.40%; P=0.003) and gained less lean mass (LM%: S=-1.46, NS=3.21%; P=0.004). Stunted girls gained less lean mass (S=7.87 kg, NS=11.96 kg; P=0.032) and had significantly higher values of FM% at follow-up when compared with their baseline values (P=0.008), whereas non-stunted girls had a non-significant difference in FM% over time (P=0.386). These findings are important to understand the factors involved in the increased prevalence of overweight and obesity among poor populations, which appear to be associated with hunger during infancy and/or childhood.
