Regular exercise is important for the maintenance of good health, but many people do very little exercise. There are public health concerns about activating the sedentary and, from an epidemiological measurement perspective, there are advantages in assessing physical inactivity. Using pooled data from 17,053 participants in Australian population surveys, we identified 5078 people (29.7%) who could be classified as sedentary in their recreational exercise habits. Logistic regression analyses found the inactive to be more likely to be older, less well educated, and to have lower incomes. The main reasons given for not exercising were no time (33%), being physically unable (23%), and not wanting to exercise (13%): these were more likely to be reported by those who were older, and who had lower incomes; the only exception was that being 55 years or older was not associated with having less time. Women were more likely to report being physically unable to exercise. Lower income was associated with being physically unable, and with not wanting to exercise. Those with children, while wanting to exercise, were more likely to report having no time. The greatest health benefits will result from the sedentary becoming more active, and inexpensive and convenient activities such as walking need to be emphasized.
经常锻炼对于保持健康很重要，但很多人很少锻炼。公众健康领域关注如何让久坐不动的人动起来，而且从流行病学测量的角度来看，评估身体活动不足有其益处。利用澳大利亚人口调查中17053名参与者的汇总数据，我们确定了5078人（占29.7%），他们在休闲锻炼习惯方面可被归类为久坐不动。逻辑回归分析发现，不活动的人更有可能年龄较大、受教育程度较低且收入较低。不锻炼的主要原因是没有时间（33%）、身体无法锻炼（23%）以及不想锻炼（13%）：年龄较大和收入较低的人更有可能报告这些原因；唯一的例外是55岁及以上的人报告没有时间的情况并不多见。女性更有可能报告身体无法锻炼。低收入与身体无法锻炼以及不想锻炼有关。有孩子的人虽然想锻炼，但更有可能报告没有时间。久坐不动的人变得更加活跃将带来最大的健康益处，因此需要强调像步行这样便宜又方便的活动。
