Abstract

Patterns of physical activity (PA) that optimize both fitness and fatness may better predict 22 cardiometabolic health. Reduced rank regression (RRR) was applied to identify combinations of the 23 type (e.g. football vs. skipping), location and timing of activity explaining variation in 24 cardiorespiratory fitness (CRF) and Body Mass Index (BMI). Multivariable regressions estimated 25 longitudinal associations of PA pattern scores with cardiometabolic health in n=579 adolescents aged 26 13-17yrs from the Malaysian Health and Adolescent Longitudinal Research Team study. PA pattern 27 scores in boys were associated with higher fitness (r=0.3) and lower fatness (r=-0.3), while in girls 28 pattern scores only associated with higher fitness (r=0.4) (fatness, r=-0.1). Pattern scores changed by 29 β=-0.01, 95% confidence interval (CI) -0.04, 0.03 and β=--0.08 (95% CI -0.1, -0.06) per year from 13-17y 30 in boys and girls respectively. Higher CRF and lower BMI were associated with better cardiometabolic 31 health at 17y but PA pattern scores were not in either cross-sectional or longitudinal models. RRR 32 identified sex-specific PA patterns associated with fitness and fatness but variation explained was 33 small. PA pattern scores changed little through adolescence, which may explain limited evidence of 34 health associations. Objective PA measurement may improve RRR for identifying optimal PA patterns 35 for cardiometabolic health.
