摘　　要：目的 探讨地中海膳食模式与中老年人骨密度的关系,为骨健康的营养防控提供参考。方法 于2018年7月—2019年2月纳入乌鲁木齐市45岁及以上社区居民909人,使用超声骨密度仪测定跟骨骨密度,用半定量食物频率问卷采集膳食摄入信息并应用地中海膳食模式进行评分,通过单因素及多元线性回归分析地中海膳食评分和骨密度的影响因素以及两者的关系。结果 不同性别(t=-2.199,P=0.028)、文化程度(F=6.986,P=0.001)的人群地中海膳食模式评分存在统计学差异;不同性别(t=-4.632,P<0.001)、年龄(F=19.753,P<0.001)、吸烟情况(t=3.617,P<0.001)、体力活动水平(F=5.858,P=0.003)、睡眠时长(F=6.651,P=0.001)人群的骨密度T值存在统计学差异,多元线性回归结果显示中老年女性人群地中海膳食模式评分与骨密度T值呈正相关(β=0.090,P=0.024),男性人群模型未见统计学意义。结论中老年女性地中海膳食与骨密度水平呈正相关,建议中老年居民调整膳食,保护骨骼健康。Objective To explore the relationship between Mediterranean dietary pattern and bone mineral density(BMD)in the middle-aged and elderly,so as to provide reference for nutritional prevention and control of bone health.Methods A total of 909 community residents aged 45 and above in Urumqi were enrolled from July 2018 to February 2019.The calcaneal bone mineral density(BMD)was measured by ultrasonic BMD device.The dietary intake information was collected by semiquantitative food frequency questionnaire and scored by Mediterranean dietary pattern.Univariate and multiple linear regression were used to analyze the influencing factors of Mediterranean dietary score and bone mineral density and the relationship between them.Results There were significant differences in the scores of Mediterranean dietary patterns among people of different genders(t=-2.199,P=0.028)and educational levels(F=6.986,P=0.001).There were significant differences in BMD T value among different genders(t=-4.632,P<0.001),age(F=19.753,P<0.001),smoking(t=3.617,P<0.001),physical activity level(F=5.858,P=0.003),and sleep duration(F=6.651,P=0.01).The results of multiple linear regression showed that there was a positive correlation between Mediterranean dietary pattern score and bone mineral density T value in the middle-aged and elderly women(β=0.090,P=0.024),while there was no statistical significance in male population model.Conclusion There is a positive correlation between Mediterranean diet and bone mineral density in middle-aged and elderly women.It is suggested that middle-aged and elderly residents adjust their diet to protect bone health.
