Correlation analysis of blood lipid level and nutritional status of elderly in Wuhan city

Abstract

Objective To explore the relationship between blood lipid level and nutritional status of the aged population in Wuhan. Methods A total of 1 634 elderly people who had taken physical examinations between December 2015 and December 2016 were selected as the research objects.Medical examination and dietary structure investigation were carried out successively.The blood test results were recorded, and the dietary structure and the nutrient intake of hyperlipidemia patients and normal population, and the correlation between nutrient intake and the lipid levels were analyzed. Results Among the 1 634 elderly people, 632 were found as hyperlipidemia patients, and the levels of high density lipoprotein (HDL) cholesterol, total cholesterol (TC) and triglyceride (TG) of the male ones were shown to be significantly lower than female, with diastolic blood pressure (DBP) increased significantly, and the differences were statistically significant (P 0.05). The intake of milk, fish, fruits, vegetables, beans and bean products, and nuts of the elderly people was significantly less than the recommended intake, and the content of salt, edible oil, meat, cereals and potatoes were significantly increased, with statistically significant difference (P<0.05). Vitamin A, fat, protein and energy in the hyperlipemia group were increased significantly compared with normal group, yet the vitamin C intake was significantly reduced, and the differences were statistically significant (P<0.05). The higher the vitamin A, fat and protein, the greater the likelihood of occurrence of hyperlipidemia (P<0.05), and the higher the level of vitamin C, the smaller the likelihood of occurrence of hyperlipidemia (P<0.05). Conclusions Unbalanced diet is the leading cause of elevated blood lipid levels.The increasing intake of vitamin C and the reduced intake of vitamin A, protein and energy, improved dietary habits, and regular examinations can help to reduce the blood lipid levels.
