To compare the prevalence of class-I, II and III obesity in Australian adults between 1995, 2007-08 and 2011-12.
Prevalence data for adults (aged 18+ years) were sourced from customised data from the nationally representative National Nutrition Survey (1995), the National Health Survey (2007-08), and the Australian Health Survey (2011-12) conducted by the Australian Bureau of Statistics. Obesity classifications were based on measured height and weight (class-I body mass index: 30.0-34.9 kg/m(2), class-II: 35.0-39.9 kg/m(2) and class-III: ≥ 40.0 kg/m(2)). Severe obesity was defined as class-II or class-III obesity.
Between 1995 and 2011-12, the prevalence of obesity (all classes combined) increased from 19.1% to 27.2%. During this 17 year period, relative increases in class I, II and III obesity were 1.3, 1.7 and 2.2-fold respectively. In 2011-12, the prevalence of class I, II and III obesity was 19.4, 5.9 and 2.0 per cent respectively in men, and 16.1, 6.9 and 4.2 per cent respectively in women. One in every ten people was severely obese, increasing from one in twenty in 1995, and women were disproportionally represented in this population. Obesity prevalence increased with increasing levels of area-level socioeconomic disadvantage, particularly for the more severely obese classes. Severe obesity affected 6.2% and 13.4% in the least and most disadvantaged quintiles respectively.
Over the last two decades, there have been substantial increases in the prevalence of obesity, particularly the more severe levels of obesity. This study highlights high risk groups who warrant targeted weight gain prevention interventions.
比较1995年、2007 - 2008年以及2011 - 2012年澳大利亚成年人中I类、II类和III类肥胖症的患病率。
成年人（18岁及以上）的患病率数据来自澳大利亚统计局进行的具有全国代表性的全国营养调查（1995年）、全国健康调查（2007 - 2008年）以及澳大利亚健康调查（2011 - 2012年）的定制数据。肥胖分类基于测量的身高和体重（I类体重指数：30.0 - 34.9千克/平方米，II类：35.0 - 39.9千克/平方米，III类：≥40.0千克/平方米）。重度肥胖定义为II类或III类肥胖。
在1995年至2011 - 2012年期间，肥胖症（所有类别合计）的患病率从19.1%增至27.2%。在这17年期间，I类、II类和III类肥胖症的相对增幅分别为1.3倍、1.7倍和2.2倍。在2011 - 2012年，I类、II类和III类肥胖症的患病率在男性中分别为19.4%、5.9%和2.0%，在女性中分别为16.1%、6.9%和4.2%。每十人中就有一人患有重度肥胖症，这一比例高于1995年的二十分之一，并且女性在这一人群中所占比例过高。肥胖症患病率随地区层面社会经济劣势程度的增加而上升，尤其是对于更重度肥胖的类别。在最不具劣势和最具劣势的五分之一人群中，重度肥胖症的影响分别为6.2%和13.4%。
在过去二十年中，肥胖症患病率大幅上升，尤其是更严重程度的肥胖症。本研究突出了那些需要针对性体重增加预防干预措施的高危人群。
