中国农村老年女性腰痛与抑郁症状的相关性

  目的  探讨中国农村老年女性腰痛与抑郁症状的相关性。  方法  使用2015年中国健康与养老追踪调查（China Health and Retirement Longitudinal Study，CHARLS）数据，纳入60岁及以上农村女性作为研究对象，计算简版流调中心抑郁量表（10-item center for epidemiological studies depression Scale，CESD-10）得分，将研究对象分为抑郁组和非抑郁组。采用倾向评分匹配（propensity score matching，PSM）平衡与抑郁症状有关的协变量，利用单因素非条件Logistic回归分析腰痛与抑郁症状的相关性。  结果  共纳入1 668名研究对象，平均年龄（67.51±5.90）岁，腰痛患病率为30.22%（95% CI:28.02% ~ 32.48%），抑郁症状患病率为46.04%（95% CI:43.63% ~ 48.47%），抑郁症状平均得分为（10.13±7.00）。PSM 1:1匹配协变量后，单因素非条件Logistic回归分析显示农村老年女性腰痛与抑郁症状有关（OR=2.901，95% CI:2.002 ~ 4.203，P < 0.001）。  结论  中国农村老年女性腰痛与抑郁症状风险增加有关。

Correlation between depression and low back pain of elderly women in rural areas of China

  Objective  To explore the correlation between depression and low back pain of elderly females in rural areas of China.  Methods  Data comes from China Health and Retirement Longitudinal Study (CHARLS) in 2015. All women aged 60 years old and over in rural areas were included in the study. The subjects were divided into depression group and non-depression group by the scores of the 10-item center for experimental studies depression scale (CESD-10). The covariates related to depressive symptoms were balanced by the propensity score matching (PSM), and the correlation between low back pain and depression was analyzed by univariate unconditional Logistic regression.  Results  A total of 1 668 subjects were enrolled, with an average age of (67.51 ±5.90) years. The prevalence of low back pain and depressive symptoms were 30.22% (95% CI:28.02%-32.48%) and 46.04% (95% CI:43.63%-48.47%), and the average score of depressive symptoms were (10.13 ±7.00) points. After using PSM 1:1 to match the covariates, the results of univariate unconditional Logistic regression analysis showed that there was a correlation between depression and low back pain of elderly women in rural areas of China (OR=2.901, 95% CI:2.002-4.203, P < 0.001).  Conclusions  There is an association between low back pain and the risk of depression in elderly females of rural areas in China.
