Mean differences in sedentary behavior and physical activity among 46-year-old adults born at term and postterm from Northern Finland Birth Cohort 1966. Mean differences in device-measured sedentary behavior (min day⁻¹) (A), light-intensity physical activity (LPA; min day⁻¹) (B), moderate-intensity physical activity (MPA; min day⁻¹) (C), and vigorous-intensity physical activity (VPA; min day⁻¹) (D) in adults born postterm (n = 805) compared with term-born control participants (zero line) (n = 2645) analyzed by multiple linear regression (95% CIs indicated by error bars). Sedentary behavior, LPA, MPA, and VPA were measured by a wrist-worn accelerometer-based Polar Active monitor. Sedentary behavior was assessed as all activity with an intensity of 1-2 metabolic equivalents of task (MET), LPA as all physical activity with an intensity of 2-3.5 MET, MPA as all activity with an intensity of 3.5-5 MET, and VPA as all activity with an intensity of at least 5 MET. Analyses were adjusted for 3 models, as described in the text. P values indicate 2-sided statistical significance for differences between values compared with adults born at term.
