Asian ancestry and birth length are associated with height among females during adolescence
Abstract
Greater rate of height gain during adolescence and greater attained height in adulthood have been identified as risk factors for later breast cancer risk. The Female Adolescent Maturation studies (FAM1, 2, 3) examined adolescent diet, physical activity, maturation and their relationship with body size. We examined the association of early life factors with mean height gain between FAM1 to 2 (9–16yrs, n=99), and FAM2 to 3 (11–19yrs, n=63) and attained height in girls at FAM3 (13–19yrs, n = 63). Attained height was defined as height in girls at FAM3. Information on birth parameters (weight, length, gestational age) and type of infant feeding were obtained via questionnaire. Mean height gain was 4.66 cm/yr (FAM1 to 2) and 2.4 cm/yr (FAM2 to 3). Although mean height gain was not significantly different between Asian and white ancestral groups, mean attained height was different (p = 0.0002). Lower % Asian ancestry predicted greater FAM 2 to 3 height gain (p=0.02, R= 0.52) adjusting for age and birth parameters. Attained height was regressed on age, % Asian ancestry, birth parameters, and age at menarche. Longer birth length was associated with greater attained height in girls at FAM3 (p=0.002, R=0.33). No effect of feeding or gestational age was observed on height gain or attained height. In conclusion, birth length and Asian ancestry are associated with attained height and gain in height during adolescence, respectively.
