目的 :了解老年人体格状况及几项常用生化指标 ,为实施心血管疾病的一级预防及其干预措施提供科学依据。方法 :对长沙市 130例老年人的身高、体重、血压、血糖、血清胆固醇、血清钙、锌、铜进行测定 ,并计算铜/锌比值。结果 :按性别分组 ,测定指标进行t检验无统计学意义 ;血清铜 /锌比值偏高者占 73.8% ;各单因素分析 :老年人收缩压与其年龄、身体质量指数、血糖、血清铜相关 ;血清铜与收缩压、舒张压、血清锌及铜 /锌比值相关。进一步的回归分析提示 :老年人血糖、年龄影响其收缩压水平 (P <0 .0 1) ;血清铜与血清锌、铜 /锌比值、收缩压呈正相关 (P <0 .0 1)。结论 :研究提示老年人的血糖增高对血压可能有影响 ,应注意膳食中碳水化合物的供给量及所占热能比例。老年人铜 /锌比值高于正常 ,怎样供给适宜的铜 /锌比值饮食 ,亟待进一步研究。
Objectives: To understand the physical status of the elderly and several commonly used biochemical indicators to provide scientific basis for the implementation of primary prevention of cardiovascular disease and intervention measures. Methods: The height, weight, blood pressure, blood glucose, serum cholesterol, serum calcium, zinc, and copper in 130 elderly people in Changsha were measured and the copper/zinc ratio was calculated. RESULTS: According to gender, the t-test was not statistically significant. The ratio of serum copper/zinc was 73.8%. The univariate analysis showed that systolic blood pressure was related to age, body mass index, blood glucose and serum copper. Serum copper is associated with systolic, diastolic, serum zinc and copper/zinc ratios. Further regression analysis suggested that elderly patients’ blood glucose and age affected their systolic blood pressure (P < 0.01); serum copper had a positive correlation with serum zinc, copper/zinc ratio and systolic blood pressure (P <0.01). Conclusion: The study suggests that the increase of blood glucose in the elderly may have an impact on blood pressure. Attention should be paid to the supply of carbohydrate and the proportion of heat energy in the diet. The copper/zinc ratio in the elderly is higher than normal, and how to provide a suitable copper/zinc ratio diet requires further study.
