Determinants of exercise among children. II. A longitudinal analysis

Area of Science:

• Pediatric Health
• Social Psychology
• Behavioral Science

Background:

• Physical activity is crucial for preventing cardiovascular disease in children.
• Sedentary habits in childhood often persist into adulthood, highlighting the need to understand exercise determinants.
• Social learning theory provides a framework for examining influences on children's physical activity.

Purpose of the Study:

• Identify social learning variables related to children's exercise.
• Investigate the longitudinal predictive value of these exercise determinants.
• Understand gender-specific and age-related patterns in physical activity influences.

Main Methods:

• Longitudinal study involving 111 families across two phases (grades 5-6 and 8-9).
• Data collected from mothers at both phases and fathers at Phase 2.
• Utilized simultaneous stepwise regression analyses to identify predictors of physical activity.

Main Results:

• Child's enjoyment was the primary Phase 1 predictor.
• Phase 2 predictors varied by gender: girls influenced by exercise knowledge, mother's activity, and social support; boys by self-efficacy, knowledge, parental modeling, and sports media interest.
• Longitudinally, mother's self-efficacy, enjoyment, and child's self-efficacy were key for girls, while only child's knowledge predicted for boys.
• Inclusion of father's data nearly doubled predictive power for both genders.

Conclusions:

• Family socialization significantly impacts children's exercise habits.
• Determinants of physical activity differ between genders and evolve over time.
• Parental and social influences are critical for promoting lifelong physical activity.
