Background The role of infant growth in adiposity remains unclear. Methods We used multivariable linear regression, with inverse probability weighting and multiple imputation to account for loss to follow‐up, in a population‐representative C hinese birth cohort, ‘ C hildren of 1997’ in H ong K ong, to examine, in terms births, the adjusted association of infant (birth to 12 months) weight growth trajectories with body mass index ( BMI ) ( n = 6861, 88% follow‐up), waist‐to‐height ratio ( WHtR ), and waist‐to‐hip ratio ( WHR ) ( n = 5398, 69% follow‐up) at ∼14 years. Results Infant weight growth trajectories had graded associations with adolescent BMI and WHtR but not with WHR , such that compared with adolescents born light with slow infant growth, adolescents born heavy with fast infant growth had higher BMI z‐score [0.60, 95% confidence interval ( CI ) 0.49, 0.70], higher WHtR z‐score (0.17, 95% CI 0.08, 0.26) but similar WHR z‐score (−0.02, 95% CI −0.11, 0.08), adjusted for sex, gestational age, parental education, parental BMI , parental height, and parental place of birth. Conclusions Varying associations of infant growth with different adiposity measures suggest a complex role of infant growth in long‐term health, perhaps because infant growth, or its underlying drivers, influences build and body composition as well as adiposity.
