目的研究舟山海岛老年人骨质疏松症的影响因素。方法对随机选择的舟山海岛地区2个社区内居住5年以上的186例海岛老年人进行骨密度检测,同时测量体质指数、血钙、血磷、尿钙、尿磷和血碱性磷酸酶(AKP)等指标,并进行问卷调查,了解研究对象的性别、年龄、每天运动时间、日照时间、慢性疾病、每天饮用牛奶、吸烟情况、饮水情况、居住环境、卧具条件、精神状况、睡眠时间等信息;对结果采用非条件Logistic多元回归进行分析。结果186例调查对象患骨质疏松症67人,其中男性患病率34.7%(26/75),女性患病率36.9%(41/111),二者差异无统计学意义(P>0.05);骨质疏松组的年龄大于对照组(P<0.01),血AKP高于对照组(P<0.05),而骨质疏松组体质指数低于对照组(P<0.05),每天运动时间大于1h的人数、每天日照时间大于2 h的人数、每日饮牛奶大于250 m l的人数均少于对照组(P<0.05,P<0.01);其他观察指标与对照组比差异无统计学意义(P>0.05)。经非条件Logisitic回归分析,高体质指数、每天运动、日照时间长、饮牛奶是海岛老年人骨质疏松症的保护因子(P<0.05)。而高年龄、血AKP增高是骨质疏松症的危险因子(P<0.05)。结论舟山海岛老年人的骨质疏松症与年龄、体质指数、运动、日照时间、饮牛奶和AKP有关。
Objective To study the influencing factors of osteoporosis in Zhoushan island elderly. Methods BMD was measured in 186 randomly selected island communities in Zhoushan island area for more than 5 years. Body mass index, blood calcium, serum phosphorus, urinary calcium, urinary phosphorus and blood alkaline phosphatase AKP) and other indicators, and conducted a questionnaire survey to understand the gender, age, daily exercise time, sunshine time, chronic diseases, daily drinking of milk, smoking, drinking water, living environment, bedding conditions, mental status, sleep time, etc. Information; the results using non-conditional Logistic multiple regression analysis. Results There were 67 osteoporosis cases in 186 subjects, of which the prevalence was 34.7% (26/75) in males and 36.9% (41/111) in females. There was no significant difference between the two groups (P> 0.05) (P <0.01). The serum AKP was higher in the osteoporosis group than in the control group (P <0.05), but the osteoporosis group had lower body mass index than the control group (P <0.05) (P <0.05, P <0.01). There was no significant difference between the other indexes and the control group (P <0.05), while the number of people who consumed more than 250 ml of milk per day was less than that of the control group > 0.05). By non-conditional Logisitic regression analysis, high body mass index, daily exercise, long sunshine time, drinking milk is a protective factor of island elderly osteoporosis (P <0.05). The higher age, elevated blood AKP is a risk factor for osteoporosis (P <0.05). Conclusion Osteoporosis in the elderly in Zhoushan island is related to age, body mass index, exercise, sunshine duration, drinking milk and AKP.
