Lower socioeconomic status (SES) may be related to inactivity lifestyle; however, the association between SES and physical inactivity has not been sufficiently investigated in Japan.
The study population is the participants of NIPPON DATA2010, which is a prospective cohort study of the National Health and Nutrition Survey 2010 in Japan. They were residents in 300 randomly selected areas across Japan. This study included 2,609 adults. Physical activity was assessed by physical activity index (PAI) calculated from activity intensity and time. The lowest tertile of PAI for each 10-year age class and sex was defined as physical inactivity. Multivariable logistic regression analyses were conducted to examine the association of SES (employment status, educational attainment, living status, and equivalent household expenditure (EHE)) with physical inactivity.
In the distribution of PAI by age classes and sex, the highest median PAI was aged 30-39 years among men (median 38.6), aged 40-49 years among women (38.0), and median PAI was decreased with increasing age. Multivariable-adjusted model shows that not working was significantly associated with physical inactivity after adjustment for age in all age groups and sexes. Not living with spouse for adult women and elderly men was significantly associated with physical inactivity compared to those who living with spouse. However, neither educational attainment nor EHE had any significant associations with physical inactivity.
The result indicated that physical inactivity was associated with SES in a general Japanese population. SES of individuals need to be considered in order to prevent inactivity lifestyle.
较低的社会经济地位(SES)可能与不活跃的生活方式有关;然而,SES 与身体不活动之间的关系在日本尚未得到充分研究。
研究人群为 NIPPON DATA2010 的参与者,这是日本 2010 年国家健康和营养调查的一项前瞻性队列研究。他们是日本 300 个随机选定地区的居民。本研究包括 2609 名成年人。身体活动通过活动强度和时间计算得出的体力活动指数(PAI)来评估。每个 10 岁年龄组和性别中 PAI 的最低三分位数被定义为身体不活动。进行多变量逻辑回归分析,以检查 SES(就业状况、教育程度、居住状况和家庭等效支出(EHE))与身体不活动的关系。
在按年龄组和性别划分的 PAI 分布中,男性中 30-39 岁年龄组的 PAI 中位数最高(中位数为 38.6),女性中 40-49 岁年龄组的 PAI 中位数最高(中位数为 38.0),且 PAI 中位数随年龄增长而降低。多变量调整模型显示,在所有年龄组和性别中,与年龄调整后不工作与身体不活动显著相关。与与配偶同住的人相比,成年女性和老年男性不与配偶同住与身体不活动显著相关。然而,教育程度和 EHE 均与身体不活动无显著关联。
结果表明,身体不活动与日本一般人群的 SES 有关。为了预防不活跃的生活方式,需要考虑个人的 SES。
