Obesity and underweight trends in Hong Kong primary school children

Track 5: Populations and population health Session 29: Epidemiology T5:S29:01 The implications of differential trends in weight and waist circumference on population level obesity monitoring Gearon, E.*; Tanamas, S.; Loh, V.; Stevenson, C. and Peeters, A. Monash University; Baker IDI Heart and Diabetes Institute; Queensland University of Technology; Deakin University We aimed to quantify discordance in changes to waist circumference (WC) and weight between 1989 and 2012, and implications for trends in obesity classification for urban Australian adults. Using three nationally representative surveys from 1989, 2000 and 2012, we selected urban Australian adults aged 25 to 69 years with measured height, weight and WC. Linear regression was used to quantify increases in WC over time adjusted for weight, age and smoking status, and stratified by sex. We additionally quantified age-standardised trends in obesity prevalence classified by WC and/or body mass index (BMI) for each survey, and compared the proportion of individuals captured as obese according to BMI and WC, BMI but not WC, and WC but not BMI. Between 1989 and 2012, WC increased significantly more than would be expected from increases in weight, by 6.7cm (95% CI 6.2, 7.2) and 2.8cm (1.5, 4.1) for women (W) and men (M), respectively. While the proportion of women and men identified as obese between 1989 and 2012 according to BMI but not WC did not substantially change (2% to 1% (W) and 3% to 3% (M)), we observed increases in the proportion identified as obese according to BMI and WC (12% to 24% (W) and 9% to 24%(M)), and the proportion identified as obese according to WC but not BMI (4% to 19% (W) and 5% to 11%(M)). The nature of obesity may be changing for urban Australian adults, and as a result WC may be a more comprehensive indicator of obesity for both Australia and internationally. T5:S29:02 Daytime napping and the risk of metabolic diseases: Dose-response meta-analysis Yamada, T.*; Shojima, N.; Yamauchi, T. and Kadowaki, T. Department of Diabetes and Metabolic Diseases, University of Tokyo Background: Sleep is an important component of a healthy life. The habit of napping is also widely prevalent around the world. Aims: We performed a meta-analysis to investigate the association between napping and the risk of metabolic diseases, and to quantify the potential dose-response relation. Key Methods: We searched electronic databases for articles published up to 2015. The adjusted relative risk and 95% confidence interval were calculated with the random effect model. Dose-response relations were also evaluated.

False positive error in the analysis of paired quality of life data

Background and purposes: The World Health Organization Quality of Life questionnaire (WHOQOL) is widely used to assess quality of life in the world. Although the WHOQOLTaiwan version has also been developed well in Taiwan, the QOL of some people cannot be assessed using the WHOQOL-Taiwan version, because about 70% of the residents of Taiwan use the local dialect, Taiwanese Southern Min, as their everyday language. In particular, more than half of the elderly cannot read or understand Chinese characters. Therefore, developing a WHOQOL for Minnanspeaking people living in Taiwan (WHOQOL-MV) is warranted.This journal issue entitled: Abstracts of the 11th Annual Conference of the International Society for Quality of Life Research ... 2004
