Association between objectively measured physical activity and longitudinal changes in body composition in adolescents: the Tromso study fit futures cohort.

ABSTRACT:

Objectives

Physical activity may be important in deterring the obesity epidemic. This study aimed to determine whether objectively measured physical activity in first year of upper secondary high school predicted changes in body composition over 2 years of follow-up in a cohort of Norwegian adolescents (n=431).

Design

A longitudinal study of adolescents (mean age of 16 (SD 0.4) at baseline, 60.3% girls) participating in the Fit Futures studies 1 (2010-2011) and 2 (2012-2013).

Setting

All eight upper secondary high schools in two municipalities in Northern Norway.

Participants

Students participating in both studies and under the age of 18 at baseline and with valid measurement of physical activity at baseline and body composition in both surveys.
