Abstract

Background: Macrosomia (birthweight ≥4 kg) may alter the associations of physical activity (PA) and screen time (ST) throughout childhood with later cardiometabolic risk. Objective: To investigate associations of PA and ST over a 4–6-year follow-up period with cardiometabolic outcomes in preteens (9–11-year-olds) who were born to mothers with previous macrosomic delivery. Methods: This is an analysis of 402 preteens from the ROLO study, who were born to mothers that previously delivered an infant with macrosomia. Parental-reported measures of PA and ST were obtained in early childhood at 5-years of age. Preteen self-reported PA, parental-reported ST, anthropometry, dual-energy x-ray absorptiometry, blood pressure, heart rate, cardiorespiratory endurance, and blood biomarkers were obtained at 9–11-years. Crude and adjusted linear regression models explored associations and the interaction of birthweight was investigated in all models. Results: Early childhood PA and ST at the 5-year follow-up were not related to preteen cardiometabolic outcomes. In adjusted models, higher preteen PA was associated with lower sum of skinfolds (B = −3.00, 95% CI −5.98, −0.02, p = 0.048) and higher cardiorespiratory endurance (B = 0.50, 95% CI 0.20, 0.80, p = 0.001) at the same time point. No strong evidence for modification by birthweight was found. Conclusion: Higher preteen PA may have potential benefits for cardiometabolic health, irrespective of birthweight.
