Background: This paper aimed to evaluate the effects of an integrated physical fitness curriculum on the physical fitness of Hong Kong preschoolers aged 3-6 years over a period of three years.Methods: Three cross-sectional studies were conducted, one in each of the academic years from 2015/2016 to 2017/2018 on preschoolers’ physical fitness. The integrated physical fitness curriculum was implemented in the second term of the three years in all participating kindergartens, with the data collected in the first year as the baseline. The second data collection was done in 2016/2017 and the last one in 2017/2018. The outcome measures included the preschoolers’ body mass indices and their physical fitness parameters like sit and reach, standing long jump, bean bags throwing, balance beam walking, and continuous jump with both feet. Ethical approval was obtained from the Human Subjects Ethics Committee of The Education University of Hong Kong.Results: The study enrolled 11,181, 10,815, and 6,309 preschoolers in the academic years 2015/2016, 2016/20017, and 2017/2018 respectively. The participants aged 4, 5, and 6 demonstrated significant improvement in most physical fitness parameters in 2016/2017 and 2017/2018 as compared with those of the same age in 2015/2016. Those aged 3, who had never been exposed to any of the interventions, had poorer performance in most physical fitness parameters. Significant improvements in both body mass indices and their physical fitness parameters were evidenced after the interventions.Conclusion: An integrated physical fitness curriculum can enhance the physical fitness of Hong Kong preschoolers for better health. Copyright © 2019 International Journal of Science and Healthcare Research.

Objective. The reliability and validity of Stunkard's Figure Rating Scale (FRS) as a measure of current body size (CBS) was established in Western adolescent girls but not in non-Western population. We examined the validity and test-retest reliability of Stunkard's FRS in assessing CBS among Chinese adolescents. Methods. In a school-based survey in Hong Kong, 5666 adolescents (boys: 45.1%; mean age 14.7 years) provided data on self-reported height and weight, CBS, perceived weight status, and health-related quality of life using the Medical Outcomes Study Short-Form version 2 (SF-12v2). Height and weight were also objectively measured. Spearman's correlation was used to assess construct validity, concurrent validity and test-retest reliability.
Results. Convergent and discriminant validity were good: CBS correlated strongly with weight and self-reported/measured BMI, but only weakly with SF-12v2. CBS correlated strongly with perceived weight status, showing concurrent validity. Spearman's correlation (r) for CBS was 0.78 for girls and 0.72 for boys indicating good test-retest reliability. Validity and reliability results did not differ significantly between senior and junior grade adolescents. Conclusion. Our findings support the use of Stunkard's FRS to measure body size among Chinese adolescents.

Objective. To examine the independent, competing, and interactive effects of perceived availability of specific types of media in the home and neighborhood sport facilities on adolescents' leisure-time physical activity (PA).
Methods. Survey data from 34 369 students in 42 Hong Kong secondary schools were collected (2006-07). Respondents reported moderate-to-vigorous leisure-time PA, presence of sport facilities in the neighborhood and of media equipment in the home. Being sufficiently physically active was defined as engaging in at least 30 minutes of non-school leisure-time PA on a daily basis. Logistic regression and post-estimation linear combinations of regression coefficients were used to examine the independent and competing effects of sport facilities and media equipment on leisure-time PA.
Results. Perceived availability of sport facilities was positively (ORboys = 1.17; ORgirls = 1.26), and that of computer/Internet negatively (ORboys = 0.48; ORgirls = 0.41), associated with being sufficiently active. A significant positive association between video game console and being sufficiently active was found in girls (ORgirls = 1.19) but not in boys. Compared with adolescents without sport facilities and media equipment, those who reported sport facilities only were more likely to be physically active (ORboys = 1.26; ORgirls = 1.34), while those who additionally reported computer/Internet were less likely to be physically active (OR boys = 0.60; ORgirls = 0.54).
Conclusions. Perceived availability of sport facilities in the neighborhood may positively impact on adolescents' level of physical activity. However, having computer/Internet may cancel out the effects of active opportunities in the neighborhood. This suggests that physical activity programs for adolescents need to consider limiting the access to computer-mediated communication as an important intervention component.
