睡眠时间与中医体质类型的关联性分析

Analysis of Correlation Between the Sleep Time and Chinese Medicine Constitutional Type

目的探求睡眠时间与中医体质类型的关系。方法以1114例健康体检人群数据库为基础,收集研究对象性别、年龄、婚姻、吸烟、饮酒、文化水平、运动水平、平均每天睡眠时间、慢性病史情况,体质调查采用中医体质量表进行评分,以体质类型得分为Y轴,以睡眠时间为X轴,绘制散点图并采用多元线性回归分析探索睡眠时间与中医体质类型的关系。结果共有1065例纳入分析。睡眠时间与中医体质关系的散点图及拟合回归直线显示,睡眠时间与平和体质呈显著正相关(r=0.123,P=0.001),8种偏颇体质与睡眠时间呈负相关关系,其中气虚质(r=-0.065,P=0.029)、阳虚质(r=-0.081,P=0.007)、阴虚质(r=-0.058,P=0.04)、痰湿质(r=-0.062,P=0.038)、气郁质(r=-0.079,P=0.008)。排除性别、年龄、婚姻、文化水平、运动水平、吸烟、饮酒、慢性疾病史的多元线性回归的结果与此相似。结论睡眠时间与中医体质类型之间存在一定关联性,应保证充足的睡眠时间,防止偏颇体质的形成。

Objective To explore the relationship between sleep time and Chinese medicine constitutional type. Methods Based on the database of physical examination of 1114 healthy subjects, information on gender, age, marital status, smoking, alcohol consumption, educational background, exercise, average daily sleep time, and chronic medical history of the subjects was collected. Investigation of constitution were scored by using Chinese medicine constitution scale. With the constitutional type score as the T axis, and the hours of sleep as the X axis, a scatter diagram was drawn. The relationship between the hours of sleep and Chinese medicine constitutional type was explored using multiple linear regression analysis method. Results Totally 1065 cases were included into analysis. Scatter diagram and the fitting regression line of sleep time and Chinese medicine constitutional type showed that sleep time was significantly positively correlated with the Balanced constitution （r = 0. 123, P = 0. 001 ）. Eight kinds of biased constitution were negatively correlated with sleep time, with Qi-deficiency constitution （ r = 0. 065, P = 0. 029 ）, Yangdeficiency constitution （r = 0. 081, P = 0. 007）, Yin-deficiency constitution （ r = 0. 058, P = 0. 04 ）, phlegm-dampness constitution （r = - 0. 062, P = 0. 038）, and Qi-stagnation constitution （r = 0. 079, P = 0. 008）. After adjusting factors like gender, age, marital status, educational background, exercise, smoking, alcohol consumption and chronic disease, the results of multiple linear regression were similar to the original results. Conclusion The sleep time seems to be correlated with Chinese medicine constitutional type. Adequate sleep time should be guaranteed to prevent the formation of biased constitution.
