The Influence of Health Behaviors During Childhood on Adolescent Health Behaviors, Health Indicators, and Academic Outcomes Among Participants from Hawaii.

BACKGROUND/PURPOSE: Health behaviors during childhood may influence adolescent health behaviors and be related to other important outcomes, but no longitudinal research has examined this in a multicultural population in Hawaii to date. This study investigated if childhood moderate to vigorous physical activity (MVPA), fruit and vegetable consumption, and sedentary behavior influence adolescent (1) MVPA, fruit and vegetable consumption, and sedentary behavior; (2) body mass index (BMI) percentile, general health, and stress; and (3) school marks and school absenteeism.

METHODS

Three cohorts of public elementary school children (fourth to sixth graders) who participated in a state-mandated after-school program in 2004, 2005, and 2006 completed baseline (demographics, MVPA, fruit and vegetable consumption, and sedentary behavior) and 5-year follow-up surveys (demographics, MVPA, fruit and vegetable consumption, and sedentary behavior; BMI, general health, stress, school marks, and absenteeism; combined follow-up n = 334; 14.76 ± 0.87 years old; 55.1% female; 53% Asian, 19.8% Native Hawaiian/other Pacific Islander, 15.3% White, and 11.9% other).

RESULTS

Regressions found that childhood MVPA (mean [m] = 45.42, standard deviation [SD] = 31.2 min/day) and fruit and vegetable consumption (m = 6.96, SD = 4.54 servings/day) predicted these behaviors in adolescence (m = 47.22, SD = 27.04 min/day and m = 4.63, SD = 3.03 servings/day, respectively, p < 0.05). Childhood sedentary behavior (m = 3.85, SD = 2.85 h/day)) predicted adolescent BMI percentile (m = 60.93, SD = 28.75, p < 0.05). Childhood fruit and vegetable consumption and sedentary behavior negatively predicted adolescent marks (B average, p < 0.05).

CONCLUSIONS

Childhood health behaviors do influence adolescent health behaviors, some health outcomes, and some academic indicators in this population, especially childhood sedentary behavior, which underlines the importance of sedentary behavior interventions.
