An overview of “The Active by Choice Today” (ACT) trial for increasing physical activity

Background Although school-based behavioral interventions for increasing physical activity (PA) in children and adolescents have been conducted, little evidence suggests that these curriculum-based approaches lead to increases in overall activity outside of program days. The overall goal of the “Active by Choice Today” (ACT) trial is to expand the body of knowledge concerning the factors that influence long-term increases in PA in underserved adolescents (low socioeconmic status, minorities) during their middle school years. Design and setting An overview of the ACT study design, theoretical framework, process evaluation, and primary hypotheses is presented. The trial involves twenty-four middle schools (1560 6th graders) in South Carolina that are randomly assigned to one of two after-school programs (motivational and life skills intervention, or general health education). Intervention The intervention integrates constructs from Self-Determination and Social Cognitive Theories to enhance intrinsic motivation and behavioral skills for PA. The intervention targets skill development for PA outside of program days and the after-school program social environment (autonomy, choice, participation, belongingness, fun, enjoyment, support) is designed to positively impact cognitive mediators (self-efficacy, perceived competence), and motivational orientation (intrinsic motivation, commitment, positive self-concept). Main hypotheses/outcomes It is hypothesized that the 17-week motivational and life skills intervention will lead to greater increases in moderate-to-vigorous PA (based on 7-day accelerometry estimates) at post-intervention as compared to the general health education program. Conclusions Implications of this innovative school-based trial are discussed.

Physical activity and inactivity in Chinese school-aged youth: the China Health and Nutrition Survey.

To describe physical activity (PA) and inactivity levels and patterns in Chinese school children (aged 6-18 y). PA and inactivity were assessed in a youth cohort enrolled in the China Health and Nutrition Survey (CHNS) in 1997. A total of 1423 males (11.5+/-3.2 y) and 1252 females (11.5+/-3.3 y). PA and inactivity were assessed by self-reported usual activity (questionnaire). Children under 10 y were assisted by parents. Approximately 84% of Chinese youth actively commute to school for a median of 100-150 min/week. A total of 72% engage in in-school moderate/vigorous (MOD/VIG) PA for a median of 90-110 min/week. Relatively few children ( approximately 8%) participate in any MOD/VIG PA outside of school. A total of 72% engage in study-related activities outside of school for a median of 420 min/week. Only 8% of Chinese school children, regardless of gender, watch television > or =2 h/day; less than 1% watch > or =4 h/day. Chores related to housework are not a part of life for Chinese school children; fewer than 20% performed these tasks. Chinese youth are unique compared to those in other developing countries because they do not perform household chores. Instead, they are under pressure to achieve scholastically. Participation in MOD/VIG PA outside of school is almost nonexistent. Current television watching habits are relatively low compared to developed countries and walking/biking is a common form of commuting. The descriptive analysis herein represents the foundation upon which future longitudinal studies of PA in this population will be based.

PHYSICAL ACTIVITY AND INACTIVITY IN CHINESE SCHOOL-AGED YOUTH

OBJECTIVE: To describe physical activity (PA) and inactivity levels and patterns in Chinese school children (aged 6–18 y). DESIGN: PA and inactivity were assessed in a youth cohort enrolled in the China Health and Nutrition Survey (CHNS) in 1997. SUBJECTS: A total of 1423 males (11.5plusminus3.2 y) and 1252 females (11.5plusminus3.3 y). MEASUREMENTS: PA and inactivity were assessed by self-reported usual activity (questionnaire). Children under 10 y were assisted by parents. RESULTS: Approximately 84% of Chinese youth actively commute to school for a median of 100–150 min/week. A total of 72% engage in in-school moderate/vigorous (MOD/VIG) PA for a median of 90–110 min/week. Relatively few children (approximately8%) participate in any MOD/VIG PA outside of school. A total of 72% engage in study-related activities outside of school for a median of 420 min/week. Only 8% of Chinese school children, regardless of gender, watch television greater than or equal to2 h/day; less than 1% watch greater than or equal to4 h/day. Chores related to housework are not a part of life for Chinese school children; fewer than 20% performed these tasks. CONCLUSION: Chinese youth are unique compared to those in other developing countries because they do not perform household chores. Instead, they are under pressure to achieve scholastically. Participation in MOD/VIG PA outside of school is almost nonexistent. Current television watching habits are relatively low compared to developed countries and walking/biking is a common form of commuting.
