Physical activity (PA) reduces risk factors related to metabolic syndrome. Rurality influences the way people incorporate physical activity into daily life. The aim of this study is to determine the association of PA level with metabolic syndrome in a rural Australian population. The influence of adiposity on these associations is also investigated.
Three cross-sectional population health surveys were conducted in south-east Australia during 2004-2006 using a random population sample (n = 1563, participation rate 49%) aged 25-74 years. PA was assessed via a self-administered questionnaire, and components of the metabolic syndrome via anthropometric measurements taken by specially trained nurses and laboratory tests.
Approximately one-fifth of participants were inactive in leisure-time and over one-third had metabolic syndrome (men 39%, women 33%; p = 0.022). There was an inverse association between level of PA and metabolic syndrome (p < 0.001). Men who were inactive in leisure-time were more than twice as likely and women more than three times as likely to have metabolic syndrome compared with those having high PA. Body mass index (BMI) is a mediating factor in the association between level of PA and metabolic syndrome.
Some PA is better than none if adults, particularly women, are to reduce their risk of metabolic syndrome and associated vascular diseases. Specialised interventions that take rurality into consideration are recommended for adults who are inactive.
体育活动（PA）可降低与代谢综合征相关的风险因素。农村地区会影响人们将体育活动融入日常生活的方式。本研究的目的是确定澳大利亚农村人口中PA水平与代谢综合征之间的关联。同时还研究了肥胖对这些关联的影响。
2004年至2006年期间，在澳大利亚东南部进行了三项横断面人口健康调查，采用随机抽样的25至74岁人群样本（n = 1563，参与率49%）。通过自我管理问卷评估PA，并通过经过专门培训的护士进行的人体测量和实验室检测评估代谢综合征的各项指标。
约五分之一的参与者在休闲时间不活动，超过三分之一的人患有代谢综合征（男性39%，女性33%；p = 0.022）。PA水平与代谢综合征之间存在负相关（p < 0.001）。与PA水平高的人相比，休闲时间不活动的男性患代谢综合征的可能性是其两倍多，女性则超过三倍。体重指数（BMI）是PA水平与代谢综合征之间关联的一个中介因素。
如果成年人，尤其是女性，要降低患代谢综合征及相关血管疾病的风险，进行一定的体育活动总比不活动要好。建议针对不活动的成年人采取考虑到农村地区情况的专门干预措施。
