背景：越来越多的证据表明，体力活动（PA）可有效降低卒中和死亡率。然而，PA水平是否与中国江西省中老年人的中风有关仍不清楚。在本研究中，我们评估了中国江西省PA与卒中风险之间的关系。研究方法：2013年11月至2014年8月，在中国江西省进行了一项横断面调查，使用标准化的问卷表格和物理测量。使用国际PA问卷对自我报告的PA进行评估。通过回答问卷自我报告卒中史。在调整社会人口学特征、生活方式因素和疾病相关危险因素后，进行多变量logistic回归分析，以评估PA水平与卒中风险之间的相关性。结果如下：共有10，398名参与者（4240名男性和6158名女性，年龄在45至97岁之间）完成了国际体力活动问卷（IPAQ）。与低强度PA相比，剧烈PA与卒中风险分级降低相关（比值比[OR]为0.763，95%置信区间[CI]为0.717-0.812，趋势P <0.001）。 而低强度PA组和中等强度PA组的个体间差异无统计学意义（P> 0.05）。 结论：与低PA相比，在中国南方的中老年人中，特别是男性中，高强度PA与卒中风险降低相关，而中度PA与卒中风险降低无关。这些结果表明，增加PA是有益的。
Background: Accumulating evidence has reported that physical activity (PA) is effective in reducing stroke and mortality. However, whether PA levels are associated with stroke in middle-aged and elderly people in Jiangxi Province of China remains unclear. In the present study, we evaluated the association between PA and the risk of stroke in Jiangxi Province of China. Methods: A cross-sectional survey was conducted in Jiangxi Province of China from November 2013 to August 2014, using standardized questionnaire forms and physical measurements. Self-reported PA was assessed using the international PA questionnaire. A history of stroke was self-reported by answering the questionnaire. Multivariate logistic regression analysis was performed to evaluate the association between PA levels and the risk of stroke after adjustment for sociodemographic characteristics, lifestyle factors, and disease-related risk factors. Results: A total of 10,398 participants (4240 men and 6158 women, aged 45 to 97 years) completed the International Physical Activity Questionnaire (IPAQ). Compared with low-intensity PA, vigorous PA was associated with graded reduction in the risk of stroke (odds ratio [OR] of 0.763, 95% confidence interval [CI] 0.717–0.812, P < .001 for trend). However, there were no significant differences between individuals in the low-intensity PA and moderate-intensity PA group (P > 0.05). Conclusions: Compared with low PA, vigorous PA, but not moderate PA, was associated with a lower risk of stroke in middle aged and elderly people in southern China, specifically among men. These findings suggested that increasing PA is beneficial.
