Changes in common activities of 3rd through 10th graders: the CHIC study

Area of Science:

• Childhood and Adolescent Health
• Behavioral Science
• Public Health

Background:

• Understanding physical activity trends in youth is crucial for public health.
• Longitudinal data on activity changes from childhood to adolescence is limited.
• Race and gender are potential factors influencing physical activity patterns.

Purpose of the Study:

• To longitudinally examine changes in physical activities and their intensity from childhood to adolescence.
• To investigate the influence of race, gender, and pubertal status on physical activity patterns.

Main Methods:

• A longitudinal study assessed common activities via questionnaire in 656 elementary school students.
• Participants included 50.5% female, with racial demographics of 83.4% Caucasian, 20.6% African-American, and 6.0% other races.
• Statistical analyses included weighted least squares and Generalized Estimating Equations (GEE) models.

Main Results:

• Girls reported more sedentary activities overall, while boys consistently reported more vigorous activities.
• Significant racial differences emerged: African-American girls reported fewer vigorous activities than other races. African-American boys reported more sedentary activities than other races in later grades.
• Advanced pubertal status in girls correlated with more sedentary activities; race influenced activity status in high school girls. Race and pubertal status did not significantly affect middle school boys' activities, but Caucasians reported more vigorous activities in high school males.

Conclusions:

• Physical activity patterns in youth are influenced by race and gender, necessitating race- and gender-specific interventions.
• Pubertal maturation is a significant factor in activity choices among middle school girls.
• Interventions should consider the interplay of race, gender, and developmental stage in promoting physical activity.
