Trajectories of maternal leisure-time physical activity and sedentary behavior during adolescence to young adulthood and offspring birthweight.

ABSTRACT:

Purpose

The objectives of the study were to determine the extent to which trajectories of maternal preconception leisure-time physical activity (LTPA) and leisure-time sedentary behavior (LTSB) during adolescence and young adulthood are associated with offspring birth weight (BW) and to test if these associations differ by offspring sex or maternal pre-pregnancy overweight-obese status.

Methods

Participants with one or more birth (n = 1408) were identified from the National Longitudinal Study of Adolescent to Adult Health. Group-based trajectory modeling was used to characterize trajectories of LTPA (frequency/week) and LTSB (hours/week) which were measured, on average, over 7 years between age 15 and 22 years. Weighted regression and Wald tests were used to estimate and tes
