Validity and test-retest reliability in assessing current body size with figure drawings in Chinese adolescents

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. © 2011 Informa Healthcare.link_to_subscribed_fulltex

Neighbourhood food environment and dietary intakes in adolescents: Sex and perceived family affluence as moderators

Objective. To examine the effects of perceived availability of fast-food shops, restaurants, and convenience stores on adolescent dietary intakes. Methods. Survey data from 34 369 students in 42 Hong Kong secondary schools were collected in 20067. Respondents reported the availability of fast-food shops, restaurants and convenience stores in the neighbourhood, and their intakes of fruit, vegetables, high-fat foods and junk food/soft drinks. For intakes of high-fat foods and junk food/soft drinks, ≤once a week was defined as low consumption and the rest moderate/high consumption. At least three servings of vegetables and two servings of fruit daily were defined as sufficient consumption. Logistic regression yielded adjusted odds ratios (OR) for each dietary intake in relation to the reported food shops. Potential effect modifications by socio-demographic factors were also examined. Results. Perceived availability of fast-food shops and convenience stores were positively associated with moderate/high consumptions of high-fat foods (ORfast 1.10 and ORcon 1.15) and junk food/soft drinks (ORfast1.10 and ORcon 1.10). Significant negative associations of the perceived availability of restaurants with intakes of vegetables and fruit were observed (ORveg 0.87 and ORfruit 0.83). The positive relationship between reporting fast-food shops with intake of junk food/soft drinks were observed only in boys and those with low perceived family affluence. The negative association of reporting restaurants with fruit consumption was found in those with low and middle perceived family affluence only. Conclusions. Perceived availability of neighbourhood fast-food shops, restaurants, and convenience stores may have a negative impact on adolescent dietary intakes particularly for those from poorer families. © 2010 Informa Healthcare.link_to_subscribed_fulltex
