Abstract

Objective. Analysis of bone mineral density (BMD) in the elderly and its associated factors according to sex. Methods. A cross-sectional study is presented herein, with a random sample of 132 noninstitutionalized elderly people. Individuals who did not use diuretics were excluded. BMD was obtained from examination of total body densitometry and its association with sociodemographic variables, lifestyle, anthropometric, and body composition was verified. Results. Mean BMD for men was 1.17 ± 0.12 g/cm(2) and for women was 1.04 ± 0.11 g/cm(2). Higher education was associated with higher BMD values in men (p < 0.05). There was a reduction in BMD in the age group 75-79 years of age in women and over 80 years of age in men (p < 0.05). Underweight was associated with significantly low BMD for both sexes (p < 0.01), while normal weight was associated with low BMD in women (p < 0.001). Discussion. The elderly with low schooling and in older age groups are more probable to also present low BMD. Lower levels of body mass index also indicated towards low BMD.

非住院老年人的骨矿物质密度：社会人口和人体测量因素的影响。

目的根据性别分析老年人的骨矿物质密度（BMD）及其相关因素。研究方法本文是一项横断面研究，随机抽取了 132 名非住院老人。未使用利尿剂的人被排除在外。通过全身密度测量检查获得 BMD，并验证其与社会人口学变量、生活方式、人体测量和身体成分的关系。结果显示男性的平均 BMD 为 1.17 ± 0.12 g/cm(2)，女性为 1.04 ± 0.11 g/cm(2)。教育程度越高，男性的 BMD 值越高（p < 0.05）。女性 75-79 岁年龄组和男性 80 岁以上年龄组的 BMD 值有所下降（p < 0.05）。体重不足与男女的 BMD 值明显偏低有关（p < 0.01），而正常体重与女性的 BMD 值偏低有关（p < 0.001）。讨论。受教育程度低和年龄较大的老年人更有可能出现 BMD 低的情况。体重指数较低也表明 BMD 较低。
