We characterized physical growth and sexual maturation in 2,579 boys, ages 10 through 16.99 years, residing in Chapaevsk, Russia in order to establish region-specific reference data. Age-specific norms were established for height, weight, and BMI, and compared to US reference data by z-score analysis, while mean heights and weights by age were compared to published national Russian data. Compared to US boys, height was slightly lower (overall z-score -0.18) at all ages except the oldest (16-16.99 yr), while weight and BMI were moderately lower (overall z-score -0.52 and -0.61, respectively). Chapaevsk boys were significantly taller (1.15 cm) and thinner (-1.28 kg) than the broader Russian sample. The median ages of stage 2 genitalia and pubic hair development were 11.9 and 12.7 years, respectively. In conclusion, Chapaevsk boys are thinner than both US and Russian boys, and have a later onset of puberty and attainment of sexual maturity than boys from other countries.
