Abstract

Fetal development may permanently affect muscle function. Indian newborns have a low mean birthweight, predominantly due to low lean tissue and muscle mass. We aimed to examine the relationship of birthweight, and arm muscle area (AMA) at birth and post-natal growth to hand-grip strength in Indian children. Grip strength was measured in 574 children aged 9 years, who had detailed anthropometry at birth and every 6-12 months post-natally. Mean (standard deviation (SD)) birthweight was 2863 (446) g. At 9 years, the children were short (mean height SD -0.6) and light (mean weight SD -1.1) compared with the World Health Organization growth reference. Mean (SD) grip strength was 12.7 (2.2) kg (boys) and 11.0 (2.0) kg (girls). Weight, length and AMA at birth, but not skinfold measurements at birth, were positively related to 9-year grip strength (β=0.40 kg per standard deviation increase in birthweight, p
