背景：目前澳大利亚的身体活动和久坐行为指南建议成年人定期进行中等到高强度的身体活动（MVPA）和力量训练（ST），并尽量减少久坐行为（SB）的时间。然而，关于这些行为在澳大利亚的具体个体和同时分布的证据很少。因此，本研究的目的是确定MVPA、ST和SB在澳大利亚成年人中具有全国代表性的患病率和社会人口学相关性。方法：采用面对面访谈法收集数据，作为2011-12年全国营养和身体活动调查的一部分。符合MVPA（>= 150分钟/周）、ST（>= 2次/周）和MVPA-ST联合指南的人口加权比例，以及被归类为“低水平SB”（= 480分钟/天）的比例。共有8.9% （95% CI: 8.1% - 9.6%）被归类为潜在“高风险”个体。那些自评健康状况较差的人、肥胖的人、年龄在25-44岁之间的人以及目前吸烟的人更有可能属于“高风险”群体。结论：绝大多数澳大利亚成年人没有达到完整的身体活动指南和/或报告过多的SB。我们的研究结果呼吁公共卫生干预，以减少澳大利亚的缺乏身体活动和SB，特别是在这些不健康行为风险最高的亚群体中。
Background: The current Australia's Physical Activity and Sedentary Behaviour Guidelines recommend that adults engage in regular moderate-to-vigorous-intensity physical activity (MVPA) and strength training (ST), and minimise time spent in sedentary behaviours (SB). However, evidence about the specific individual and concurrent distribution of these behaviours in Australia is scarce. Therefore, the aim of this study was to determine the prevalence and sociodemographic correlates of MVPA, ST and SB in a national-representative sample of Australian adults.Methods: Data were collected using face-to-face interviews, as part of the National Nutrition and Physical Activity Survey 2011-12. The population-weighted proportions meeting the MVPA (>= 150 min/week), ST (>= 2 sessions/week) and combined MVPA-ST guidelines, and proportions classified as having 'low levels of SB' (= 480 min/day). A total of 8.9 % (95 % CI: 8.1 %-9.6 %) were categorised as individuals at potentially 'high-risk'. Those with poorer self-rated health, obese individuals, those aged 25-44, and current smokers were more likely to be in the 'high risk' group.Conclusions: The large majority of Australian adults do not meet the full physical activity guidelines and/or report excessive SB. Our results call for public health interventions to reduce physical inactivity and SB in Australia, particularly among the subgroups at the highest risk of these unhealthy behaviours.
