目的：为了测量澳大利亚成年人肥胖的患病率，并研究肥胖与社会经济和生活方式因素的关系，设计：AusDiab，一项在1999年5月至2000年12月进行的横断面研究，参与者来自澳大利亚42个随机选择的地区。在20347名年龄大于或等于25岁的符合条件的人中，有11247人在当地调查点参加了体检（应答率，55%）。主要观察指标：体重指数定义的超重和肥胖（BMI; kg/m2）和腰围（cm）;社会人口因素（包括吸烟、体力活动和看电视时间）。超重和肥胖的患病率（BMI大于或等于25.0 kg/m（2）;腰围大于或等于80.0 cm [女性]或大于或等于94.0 cm [男性]）的男性和女性几乎均为60%，由BMI或腰围定义。肥胖症的流行率比1980年高出2.5倍。以腰围为标准，女性肥胖患病率高于男性（34.1% vs26.8%; P < 0.01）。较低的教育程度，较高的电视观看时间和较低的体力活动时间都与肥胖密切相关，与电视观看时间显示出更强的关系比体力活动time.Conclusions：肥胖的患病率在澳大利亚增加了一倍以上，在过去的20年。肥胖与看电视时间和较低的身体活动时间之间的强正相关证实了久坐不动的生活方式对肥胖的影响，并强调了减少久坐不动的行为以及增加身体活动对遏制肥胖流行的潜在好处。
Objective: To measure the prevalence of obesity in Australian adults and to examine the associations of obesity with socioeconomic and lifestyle factors.Design: AusDiab, a cross-sectional study conducted between May 1999 and December 2000, involved participants from 42 randomly selected districts throughout Australia.Participants: Of 20 347 eligible people aged greater than or equal to 25 years who completed a household interview, 11247 attended the physical examination at local survey sites (response rate, 55%).Main outcome measures: Overweight and obesity defined by body mass index (BMI; kg/m(2)) and waist circumference (cm); sociodemographic factors (including smoking, physical activity and television viewing time).Results: The prevalence of overweight and obesity (BMI greater than or equal to 25.0 kg/m(2); waist circumference greater than or equal to 80.0 cm [women] or greater than or equal to 94.0 cm [men]) in both sexes was almost 60%, defined by either BMI or waist circumference. The prevalence of obesity was 2.5 times higher than in 1980. Using waist circumference, the prevalence of obesity was higher in women than men (34.1% v 26.8%; P < 0.01). Lower educational status, higher television viewing time and lower physical activity time were each strongly associated with obesity, with television viewing time showing a stronger relationship than physical activity time.Conclusions: The prevalence of obesity in Australia has more than doubled in the past 20 years. Strong positive associations between obesity and each of television viewing time and lower physical activity time confirm the influence of sedentary lifestyles on obesity, and underline the potential benefits of reducing sedentary behaviour, as well as increasing physical activity, to curb the obesity epidemic.
