Objective: To investigate the comprehensive nutritional status and diet behavior of middle aged and elderly women with osteoporosis, and thereby to explore the relationship between diet behavior and comprehensive nutritional status. Methods: 311 middle-aged and elderly women with osteoporosis in Chengdu were included in this study. Mini Nutritional Assessment (MNA) was applied to assess their comprehensive nutritional status. Information of social-demographic characteristics and diet behavior (about meals, snacks and water drinking, etc.) of the subjects was collected by questionnaire. Chi square test was used to assess the differences in nutritional status among patients who have different eating behaviors. Logistic regression analysis was performed to evaluate the relationship between diet behaviors and comprehensive nutritional status. Results: The mean MNA score of subjects was 25.8±2.5. 20.3% (63/311) of the subjets were at risk of potential malnutrition, but there was no malnourished subjects found. 46.9% (46/311) of the subjects were in good appetite. 95.2% (296/311) of them had a fixed food intake each meal. 65.8% (198/311) of them had snacks every day, and the most common choice was fruit (86.4% (248/287)). 54.8% (165/311) of them had initiative drinking water habits, and the most common choice was plain boiled water (79.9%, 246/308). 76.5% (238/311) of them had daily portable water less than 1 500 ml. After adjusting the effects of age, occupation and education level, bad appetite (OR=3.50, 95%CI: 1.18-10.62), unfixed food intake (OR=7.27, 95%CI: 1.40-35.83), and seldom or never intake of snack (OR=3.71, 95%CI: 1.42-9.72) were risk factors for malnutrition risk, while tea drinking was protective factor(OR=0.31, 95%CI: 0.11-0.93). Conclusion: Risk of potential malnutrition and unhealthy diet behavior among the middle aged and elderly women with osteoporosis should be paid more attention. Unhealtghy diet behavior has a negative effect on their comprehensive nutritional status.
目的： 分析中老年骨质疏松女性的综合营养状况和饮食行为特征，探讨饮食行为对其综合营养状况的影响。 方法： 以成都市311例中老年骨质疏松女性为调查对象，应用微型营养评价法（mini nutritional assessment, MNA）分析评价其综合营养状况；通过问卷调查收集其饮食行为（正餐、加餐、饮水等）和个人基本信息；采用χ(2)检验对不同饮食行为人群综合营养状况的进行比较分析；采用多因素logistic回归模型分析饮食行为对综合营养状况的影响。 结果： 调查对象MNA评分为25.8±2.5，潜在营养不良者占20.3%（63/311），无营养不良者。调查对象食欲好者占46.9%（146/311）；每餐食量固定者占95.2%（296/311）；65.8%（198/311）的调查对象每天加餐，最常用于加餐的食物是水果[86.4%（248/287）]；主动饮水者占54.8%（165/311），饮水类型主要为白开水[79.9%（246/308）]，每日饮水量<1 500 ml者占76.5%（238/311）。调整年龄、职业和文化程度影响后，食欲不好、每餐食量不固定、偶尔/从不加餐是中老年骨质疏松女性潜在营养不良的危险因素，OR（95%CI）值分别为3.50（1.18~10.62）、7.27（1.40~35.83）、3.71（1.42~9.72）；饮茶水是该人群潜在营养不良的保护因素，OR（95%CI）值为0.31（0.11~0.93）。 结论： 中老年骨质疏松女性的潜在营养不良风险和不良饮食行为需要关注和改善，不良饮食行为对其综合营养状况产生不利影响。.
