A longitudinal study, with measurements at 15, 24, and 32 weeks of gestation, was
conducted. Time spent in moderate-to-vigorous PA (MVPA) was measured objectively. In regression
models, the relationship between time spent in MVPA at week 15 and changes in MVPA from
15 weeks to 24 or 32 weeks with fasting glucose, glycosylated hemoglobin, fasting insulin, insulin
sensitivity, and insulin response at week 24 or 32 was assessed.
