【摘要】 目的 分析健康体检者骨密度水平的影响因素，并提出防护措施。方法 选取2019年1月至2020年12月深圳市保健委员会办公室综合门诊部接受骨密度检测的健康体检者200例进行回顾性分析，统计其基本信息，分析不同体质量指数（body mass index,BMI）、不同年龄、不同性别、不同生活方式对骨密度的影响。通过多重线性回归分析，分析影响骨密度水平的主要因素。结果 与BMI为28.0～32.0kg/m~2者相比，BMI在16.0～21.9kg/m~2、22.0～27.9kg/m~2的桡骨、胫骨骨密度检测值更小，差异有统计学意义（P<0.05）。80～90岁骨密度检测结果为骨质疏松或严重骨质疏松的人数占比达71.43%,30～39岁检测结果为0。骨量减少方面，40～49岁者占比达48.39%,70～79岁者达44.00%,30～39岁者占比3.85%，差异有统计学意义（P<0.05）。男性、不吸烟者、每周3次及以上运动锻炼者、喝牛奶或定期补充其他含钙物质者，以及无长期饮酒、饮浓茶、咖啡习惯者，骨量正常人数占比更多，差异有统计学意义（P<0.05）。多重线性回归分析显示，危险因素方面为吸烟、饮酒、饮浓茶、饮咖啡（P<0.05），保护因素方面为运动、饮牛奶（P<0.05）。结论 BMI、年龄、性别、生活饮食方式等均会对健康体检者的骨密度水平造成一定影响，针对相关因素加强预防，可降低骨质疏松的发生概率。更多还原

【Abstract】 Objective To analyze the influencing factors of bone mineral density level in healthy physical examination and put forward protective measures. Methods A total of 200 health check–ups who underwent bone density testing at the comprehensive outpatient department of Shenzhen Health Care Commission Office from January 2019 to December 2020 were selected for retrospective analysis, and their basic information was counted to analyze the effects of different body mass index(BMI), different ages, different genders and different lifestyles on bone density. The main factors affecting bone mineral density levels were analysed by multiple linear regression analysis. Results Compared to those with a BMI of 28.0 to 32.0 kg/m~2, those with a BMI of 16.0 to 21.9 kg/m~2 and 22.0 to 27.9 kg/m~2 had a smaller radial and tibial bone mineral density, with a statistically significant difference(P<0.05). 71.43% of those aged 80 to 90 had osteoporosis or severe osteopenia, while those aged 30 to 39 had zero. For bone loss, 48.39% of those aged 40 to 49 years, 44.00% of those aged 70 to 79 years and 3.85% of those aged 30 to 39 years had a test result of 0. The difference was statistically significant(P<0.05). The proportion of people with normal bone mass was higher among men, non–smokers, those who exercised 3 times a week or more, those who drank milk or regularly supplemented with other calcium–containing substances, and those who did not have a long–term habit of drinking alcohol, strong tea or coffee, with a statistically significant difference(P<0.05). Multiple linear regression analysis showed that the risk factors were smoking, alcohol, tea and coffee consumption(P<0.05) and the protective factors were exercise and milk consumption(P<0.05). Conclusion BMI, age, gender, lifestyle and diet will have a certain impact on the bone mineral density level of healthy physical examinees. Strengthening prevention against relevant factors can reduce the incidence of osteoporosis.更多还原
