Joey Lightner, Brandon C. Irwin, and Matthew Chrisman

Examining this relationship in a longitudinal study, following individuals over time, would give this finding more credence. Few studies to date have examined how changes in social integration impact changes in physical activity. Social integration and physical inactivity were examined in the classic

Longitudinal Associations Between Sedentary Behavior of Adolescent Girls, Their Mothers, and Best Friends

Lennart Raudsepp and Eva-Maria Riso


The objective of this study was to examine the prospective relationship and changes in sedentary behavior between adolescent girls, their mothers and best friends over time.


The results are based on 122 girls aged 11–12 years at baseline measurement, their mothers and best friends who completed ecological momentary assessment diary for the assessment of sedentary behavior. All measurements were taken at 3 time points separated by one year. We used structural equation modeling to examine associations among sedentary behavior of adolescent girls, their mothers and best friends.


A linear growth model for adolescent girls’ and their best friends’ sedentary behavior fit the data well, revealing an overall significant increase in sedentary behavior across time. Initial levels of mothers’ and best friends’ sedentary behavior were positively related with sedentary behavior of adolescent girls. The changes of adolescent girls’ and best friends’ sedentary behavior across 3 years were positively related. Cross-lagged panel analysis demonstrated significant reciprocal effects between adolescent girls’ and best friends’ sedentary behavior. Mothers’ sedentary behavior at baseline predicted daughters’ sedentary behavior at 1-year follow-up and vice versa.


From early to midadolescence, changes in adolescent girls’ sedentary behavior were associated with changes in best friends’ sedentary behavior. These findings suggest reciprocal associations between sedentary behavior of adolescent girls and their best friends.
