Intervention and participants
The Patient-centered Assessment and Counseling for Exercise and Nutrition (PACE+) Project for adolescents was conducted from 2001– 2004. The PACE+ intervention aimed to increase physical activity and fruit and vegetable intake and decrease dietary fat and sedentary behaviors. Participants were randomly assigned to receive the PACE+ intervention or participate in a sun protection behavior change intervention (SUN). Both interventions were based on constructs from Social Cognitive Theory and the
Results
Of the 878 enrolled in the study, 690 completed 12-month measures and were included in the current analysis. There were no differences at baseline on the behaviors included in this study between completers and noncompleters (all p > .10). There were no differences in gender, age, body weight, or highest level of parent education between those randomized to the PACE+ and SUN groups. More non-white adolescents were enrolled in the PACE+ (45%) than in the SUN treatment group (38%) [37].

Discussion
In this large sample of adolescents, diet, physical activity, and sedentary behaviors did not covary over a 1-year period. Similarly, no covariation was found between physical activity and sedentary behaviors, physical activity and diet, or diet and sedentary behaviors. An implication of these results is that intervening to improve physical activity, diet, or sedentary behaviors among adolescents would be unlikely to affect any of the other behaviors positively or negatively.

Primary care prevention of cardiovascular risk behaviors in adolescents: A systematic review
2021, Preventive MedicineCitation Excerpt :Interventions without significant effects and those with obvious important biases were classified as “showing no or unclear effectiveness”. Thirteen studies measured physical activity outcomes (Table C1) (Chen et al., 2019; Kong et al., 2013; Patrick et al., 2006; Patrick et al., 2013; Saelens et al., 2002; Patrick et al., 2001; Oreskovic et al., 2016; Ortega-Sanchez et al., 2004; Rosenberg et al., 2007; Chen et al., 2017; DeBar et al., 2012; Eddy Ives et al., 2012; Fleischman et al., 2016; Love-Osborne et al., 2014; Walker et al., 2002). Reported outcomes varied across studies and included moderate-to-vigorous physical activity (MVPA), proportion of adolescents meeting physical activity guidelines, number of weekly active days, and duration of sports activities.

Results of a multi-media multiple behavior obesity prevention program for adolescents
2010, Preventive MedicineCitation Excerpt :The treatment group exemplified significant co-variation effects among behavior pairs at each timepoint, meaning that movement to A/M for one behavior increased the likelihood of moving to A/M for another behavior. Using a different methodology and only looking at 12-month data, Rosenberg et al. (2007) did not find co-variation among similar target behaviors. Our data suggest that synergy among multiple behaviors can allow for a more efficient approach to healthy weight management.
