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.
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 semi-quantitative 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.
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.
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.
