Assessment of Dietary Restraint: Psychometric Properties of the Revised Restraint Scale in Hong Kong Adolescents
Background: The psychometric properties of the Revised Restraint Scale (RRS) have been well established in western populations but not in Chinese adolescents. Purpose: This study investigated the psychometric properties of RRS and its validity in different subgroups for Hong Kong Chinese adolescents. Method: In 2007, 909 Hong Kong students aged 12 to 18 years (55.3% boys) completed a questionnaire including demographic items, RRS, Eating Attitudes Test (EAT-26), and Motivation for Eating Scale (MFES)-physical. Moreover, subjects' height and weight were measured. To examine the factor structure of RRS, the whole sample was randomly split into two groups (sample 1: N=454 and sample 2: N=455) for exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), respectively. Convergent and discriminant validity of RRS were investigated by correlating the RRS with EAT-26 and MFES-physical. Multigroup CFA was conducted to test the three-factor model of RRS in different sex, age, and weight status subgroups. Results: Results of EFA for sample 1 revealed three strongly correlated factors for the RRS construct, and were supported by the CFA results in sample 2. Multigroup CFA further suggested that the three-factor model of RRS was stable across sex, age, and weight status subgroups. Conclusions: A new three-factor model is proposed for Hong Kong adolescents in this study. In general, RRS is a reliable and valid measure of restrained eating for adolescents, regardless of sex, age, and weight status. © 2011 The Author(s).published_or_final_versionSpringer Open Choice, 21 Feb 201

Exposure to particulate air pollution at different living locations and respiratory symptoms in Hong Kong-an application of satellite information
Respiratory ill-health effects due to particulate air exposure at different geographical locations in Hong Kong that aggregate individual living locations were estimated based on satellite information. We assessed the presence of respiratory symptoms of a frequent cough or sputum in school students aged 11-20 years old (n=9,881). Daily particulate air pollution levels at students' living locations were derived from the surface extinction coefficients measured by satellite and measurements from the air pollutant monitoring stations at ground level. Adjusted odds ratio (OR) [95% CI] of respiratory symptoms was 1.047 [1.005, 1.091] per 10 g m-3 increase in PM10 concentration. Specificity tests showed that adjusted OR of having other symptoms is not significant (p=0.20-0.94). Exposures to PM10 at different geographical locations is associated with increased odds of having respiratory symptoms (cough or sputum) but not with other symptoms unrelated to air pollution. © 2010 Taylor & Francis.postprin
