Randomized controlled trial of a primary care and home-based intervention for physical activity and nutrition behaviors: PACE+ for adolescents.
OBJECTIVE Many adolescents do not meet national guidelines for participation in regular moderate or vigorous physical activity ( PA ) ; limitations on sedentary behaviors ; or dietary intake of fruits and vegetables , fiber , or total dietary fat . This study evaluated a health care-based intervention to improve these behaviors . DESIGN R and omized controlled trial . SETTING Primary care with follow-up at home . PARTICIPANTS Eight hundred seventy-eight adolescent girls and boys aged 11 to 15 years . INTERVENTIONS Two experimental conditions : ( 1 ) Primary care , office-based , computer-assisted diet and PA assessment and stage-based goal setting followed by brief health care provider counseling and 12 months of monthly mail and telephone counseling and ( 2 ) a comparison condition addressing sun exposure protection . MAIN OUTCOME MEASURES Minutes per week of moderate plus vigorous PA measured by self-report and accelerometer ; self-report of days per week of PA and sedentary behaviors ; and percentage of energy from fat and servings per day of fruits and vegetables measured by three 24-hour diet recalls . Body mass index ( calculated as weight in kilograms divided by the square of height in meters ) was a secondary outcome . RESULTS Compared with adolescents in the sun protection condition , girls and boys in the diet and PA intervention significantly reduced sedentary behaviors ( intervention vs control change , 4.3 to 3.4 h/d vs 4.2 to 4.4 h/d for girls , respectively [ P = .001 ] ; 4.2 to 3.2 h/d vs 4.2 to 4.3 h/d for boys , respectively [ P = .001 ] ) . Boys reported more active days per week ( intervention vs control change : 4.1 to 4.4 d/wk vs 3.8 to 3.8 d/w , respectively [ P = .01 ] ) , and the number of servings of fruits and vegetables for girls approached significance ( intervention vs control change , 3.5 to 4.2 servings/d vs 3.5 to 3.9 servings/d , respectively [ P = .07 ] ) . No intervention effects were seen with percentage of calories from fat or minutes of PA per week . Percentage of adolescents meeting recommended health guidelines was significantly improved for girls for consumption of saturated fat ( intervention vs control change , 23.4 % to 41.0 % vs 18.5 % to 31 % , respectively [ relative risk , 1.33 ; 95 % confidence interval , 1.01 - 1.68 ] ) and for boys ' participation in d/wk of PA ( intervention vs control change , 45.3 % to 55.4 % vs 41.9 % to 38.0 % , respectively [ relative risk , 1.47 ; 95 % confidence interval , 1.19 - 1.75 ] ) . No between-group differences were seen in body mass index . CONCLUSIONS Improvements in some diet , PA , and sedentary behaviors in adolescents can be enabled through the use of a 1-year , integrated intervention using the computer , health provider counseling , mail , and telephone . The amount of intervention received may contribute to its efficacy
