【摘要】 目的研究城区老年人的膳食模式状况及其与骨密度水平的相关性。方法收集2015-2017年参加健康体检的城区老年人的骨密度和膳食回顾问卷,采用因子分析法分析膳食模式与骨密度的相关性。结果 237名城区老年人纳入本次调查,膳食调查归纳出3类膳食模式:高脂高蛋白膳食模式、传统膳食模式和低脂高蛋白型膳食模式。采用低脂高蛋白型膳食模式和传统型膳食模式的老年人群的骨密度水平高于高脂高蛋白型膳食模式的人群,差异有统计学意义(P=0.042)。低脂高蛋白型膳食模式和传统型膳食模式因子得分越重的人群的骨密度水平越高(P=0.01),高脂高蛋白型膳食模式因子得分重的老年人的骨密度水平显著更低(P=0.016)。结论传统平衡膳食模式和低脂高蛋白膳食模式对老年人的骨密度水平的维持效果优于高脂高蛋白模式。更多还原

【Abstract】 Objective To analyze the relationship between dietary patterns and osteoporosis in urban elderly. Methods Urban elderly whose age were in 60-80 years were randomly selected to finish SFFQ twice and 3 d24 h DR once. Dietary patterns were identified by factor analysis. Bone mineral density was measured. The relationship between dietary pattern and bone mineral density was analyzed. Each factor score of dietary pattern was accorded to three digit grouping. The high marks crowd of bone mineral density was compared with that of low marks crowd in each dietary pattern. Results 237 subjects were included in the study. The dietary patterns of the elderly were divided into three groups: high fat high protein dietary pattern( HFHP),traditional dietary pattern( TD),and low fat high protein dietary pattern( LFHP) by factor analysis. The bone mineral density in LFHP and TD pattern group were statistically higher than that in HFHP group( P = 0. 042). The group with higher scores in LFHP and TD factors had higher bone mineral density( P = 0. 01). The elderly who had high scores in HFHP showed lower bone mineral density( P = 0. 016). Conclusion The LFHP and TD may have great effective on the elderly to maintain bone density.更多还原
