目的 探索健康相关生命质量高分组和低分组的生活习惯和中医体质转换分的差异。方法 从1 114例健康体检人群数据库中，分别抽取简明健康状况调查问卷（the MOS 36-item short form health survey, SF-36）的生理领域得分、心理领域得分的前27%（301例）和后27%（301例）作为高分组和低分组，比较两组的生活习惯和中医体质量表转换分。结果 SF-36生理领域和心理领域高分组和低分组的吸烟偏好比较，差异无统计学意义（P>0.05）；两组饮酒偏好、睡眠时间、中医体质量表转换分比较，差异具有统计学意义（P<0.05），其中高分组好饮酒者较多，睡眠时间为7～8 h者较多，平和质者较多，平和质转换分较高，8种偏颇体质转换分较低；心理领域高分组有运动习惯者较多（P<0.05），而生理领域高分组和低分组的运动习惯差异无统计学意义（P>0.05）。结论 SF-36高分组和低分组的生活习惯和中医体质因素存在一定差异，通过改善睡眠时间、运动习惯及偏颇体质可能会提高健康相关生命质量。
Objective To investigate the differences in living habits and converted scores of Constitution in Chinese Medicine Questionnaire (CCMQ) between patients with high and low health-related quality of life (HRQoL) scores. Methods Among 1 114 persons who underwent physical examination, 301 persons whose scores on the subscales of physical component summary (PCS) and mental component summary (MCS) respectively of 36-item short-form health survey (SF-36) ranked top 27% were enrolled as high-score group, and 301 persons whose scores ranked bottom 27% were enrolled as low-score group. The living habits and converted scores of CCMQ were compared between the two groups. Results There was no significant difference in the smoking habit between the groups with high and low scores on the subscales of PCS and MCS of SF-36 (P>0.05), while there were significant differences in the drinking habit, sleeping time, and converted scores of CCMQ between the two groups (P<0.05). Compared with the low-score group, the high-score group had significantly more persons with drinking habit, a sleeping time of 7-8 hours, and balanced constitution, a significantly higher converted score of balanced constitution, and significantly lower converted scores of 8 imbalanced constitution types. The group with a high score on the subscale of MCS had significantly more persons with an exercise habit than the group with a low score on the subscale of MCS (P<0.05), while there was no significant difference in exercise habit between the groups with high and low scores on the subscale of PCS (P>0.05). Conclusion There are certain differences in living habits and constitutions of traditional Chinese medicine between the groups with high and low scores of SF-36. Improvements in sleeping time, exercise habit, and imbalanced constitution may help to improve HRQoL.
