Muscle-strengthening activity (MSA) (e.g. weight training), confers unique health benefits. While socioeconomic status (SES) correlates with leisure time physical activity, little is known about its relation with MSA.
Cross-sectional study of a representative sample of 8993 Australian adults (>18years) who participated in the National Nutrition and Physical Activity Survey 2011-12. Information was collected on SES (income, education, socio-economic disadvantage and remoteness) and MSA participation.
17.9% (CI: 16.8-19.0) met the national guidelines for MSA (≥2 sessions/week). Men and younger adults (<35years) met MSA guidelines more than females (19.7%; CI: 18.3-21.1% vs 16.1%; CI: 14.6-17.6%; p<0.001) and older adults respectively (25.0%; CI: 22.4-27.7% vs 10.4%; CI: 8.9-11.8%; p<0.001). All SES indicators were associated with meeting the guidelines in unadjusted analyses. When adjusting for total physical activity and mutually adjusting for each socioeconomic indicator only remoteness (OR for city vs rural=1.65; CI: 1.17-2.32; p<0.001) was associated with MSA participation (education OR=1.09 for high vs low; CI: 0.80-1.47, p=0.748; income OR=1.31 for Q5 vs Q1, CI: 0.93-1.85, p=0.328; social disadvantage OR=1.04 for v.high vs v.low, CI: 0.76-1.43, p=0.855). These associations were further attenuated when adjusting for BMI, smoking status and self-rated health.
Remoteness, and to a lesser degree, education, income and social disadvantage, were independently associated with MSA participation. Public health interventions should improve access to strength training facilities, and/or increase home-based muscle-strengthening activity in remote areas.
肌肉强化活动（MSA）（例如举重）可带来独特的健康益处。尽管社会经济地位（SES）与休闲时间体育活动相关，但人们对其与 MSA 的关系知之甚少。
这是一项对参加 2011-12 年澳大利亚国家营养和身体活动调查的 8993 名澳大利亚成年人（>18 岁）的代表性样本进行的横断面研究。收集了 SES（收入、教育、社会经济劣势和偏远程度）和 MSA 参与情况的信息。
17.9%（置信区间：16.8-19.0）符合 MSA（每周≥2 次）的国家指南。男性和年轻成年人（<35 岁）比女性（19.7%；置信区间：18.3-21.1%比 16.1%；置信区间：14.6-17.6%；p<0.001）和老年成年人（25.0%；置信区间：22.4-27.7%比 10.4%；置信区间：8.9-11.8%；p<0.001）更符合 MSA 指南。在未调整分析中，所有 SES 指标均与符合指南相关。在调整总体力活动并相互调整每个社会经济指标后，只有偏远程度（城市与农村相比的比值比[OR]为 1.65；置信区间：1.17-2.32；p<0.001）与 MSA 参与相关（教育 OR=1.09，高与低相比；置信区间：0.80-1.47，p=0.748；收入 OR=1.31，Q5 与 Q1 相比；置信区间：0.93-1.85，p=0.328；社会劣势 OR=1.04，高与低相比；置信区间：0.76-1.43，p=0.855）。当调整 BMI、吸烟状况和自我评估健康状况时，这些关联减弱。
偏远程度，以及在较小程度上，教育、收入和社会劣势与 MSA 参与独立相关。公共卫生干预措施应改善获得力量训练设施的机会，并/或增加偏远地区的家庭肌肉强化活动。
