目的为了解中老年人群营养知识、饮食行为和BMI现状与受教育水平的关系。方法对南京市城乡26家养老机构和社区的1367名中老年人进行问卷调查。结果高中组和大学组营养知识水平显著高于小学组和初中组(P<0.05,P<0.01)且获取营养知识的途径明显多元化;而小学组和初中组50%的群体主要依赖广播电视。由于受教育程度高的中老年人经济收入普遍较高,间接影响到其膳食结构,他们的饮食行为更趋合理。进一步比较知识水平、年龄与BMI之间的关系,年龄影响更明显。75岁老人的消瘦和肥胖比例增加,应更加注重他们的膳食营养补充。结论受教育水平对中老年人群的营养知识和饮食行为影响显著(P=0.00),高中和大学文化程度群体营养知识和经济收入明显优于小学和初中群体;但BMI主要与年龄相关,高龄老人二端比例增加,需要更加关注。
Objective To understand the relationship between nutrition knowledge, dietary behavior, current status of BMI and educational attainment in middle-aged and elderly people. Methods A total of 1367 middle-aged and elderly people in 26 pension institutions and communities in Nanjing urban and rural areas were surveyed. Results The nutritional knowledge level of high school and university group was significantly higher than that of primary and junior high school (P <0.05, P <0.01) and the diversified access to nutritional knowledge was obvious. However, 50% of primary and junior middle school groups mainly relied on radio and television . As middle-aged and elderly people with a high level of education generally have higher economic incomes and indirectly affect their dietary structure, their eating habits are more reasonable. Further comparison of the level of knowledge, the relationship between age and BMI, the impact of age is more obvious. 75-year-olds increase the proportion of weight loss and obesity, should pay more attention to their dietary supplement. Conclusion The level of education has a significant effect on nutrition knowledge and dietary behaviors of the middle-aged and elderly population (P = 0.00). The nutrition knowledge and economic income of high school and college education groups are significantly better than those of primary and middle school students. However, BMI is mainly associated with age- Increased proportion of the two ends, need more attention.
