A comparative study of the determinants of physical activity, sedentary behaviours and dietary intake among Korean children in Korea and Canada
Bibliographic record
Abstract
Background: The rising trends in youth physical inactivity are universal, especially among ethnic minority youth populations. Even though reduced physical activity levels and increased sedentary behaviours have influenced the current epidemic of overweight and obesity in children, little attention has focused on youth physical activity among Asian populations such as Koreans. Research is needed to examine how socio-cultural factors influence health-related behaviours of Korean children in Canada, and whether they are more at risk of being physically inactive than children living in their own country. Purpose: In a series of three studies, this dissertation aimed to compare the environment and health-related behaviours of two cultural groups and then investigate which factors may be related to the differential rates of physical activity, sedentary behavior and dietary intake among Korean children in Korea and Canada. Methods: In Study 1, the reliability of a Korean translation of the Physical Activity Questionnaire for Older Children (PAQ-C) was tested with 48 bilingual children. For Study 2, 1,094 children were recruited from Canada and Korea. Measurement included anthropometric measures, physical activity levels, sedentary behaviours, dietary intake, correlates of physical activity and prevalence of obesity. Pedometers were used to measure physical activity among 198 Korean and Korean Canadian children in Study 3. Results: In Study 1, a significant test-retest correlation was found between the Korean and English versions of the PAQ-C. In Study 2, the interaction effect between group and gender was statistically significant for levels of physical activity. Statistically significant differences also emerged for sedentary behaviours between Korean and Korean Canadian children. In addition, significant differences were found in involvement in organized sports and active transportation to school between the two groups. Significant associations were also identified among the correlates of physical activity in both groups. Conclusion: This dissertation provided important and contextual information regarding the role the environment plays on health-related behaviours in Korean children in Korea and Canada. By exploring environmental influences on physical activity, dietary habits, and sedentary behaviours in relation to childhood obesity, this study may offer new understanding about the important role of socio-cultural factors on children’s health.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
