Objective: To study Chongqing in the elderly group dietary characteristics of the structure and Chongqing in the elderly population prevalence of hyperlipidemia and related influencing factors (including dietary factors and non-dietary factors) for the development of hyperlipidemia control strategies to provide a scientific basis. Methods: 1. Questionnaire: the use of a food frequency questionnaire, survey the past year food consumption frequency and consumption. Dietary quality evaluation \(2) Physical examination: all survey height, weight, waist circumference, blood pressure measurement. Laboratory testing: the collection of blood samples of all respondents, fasting blood glucose and lipid determination, determination of TG, TC, HDL-C. According to the 2002 China National Nutrition and Health Survey Project Working Group recommended that the diagnostic criteria for diagnosis of hyperlipidemia. Chongqing National Nutrition and Health Survey ≥ 40-year-old urban and rural residents, the survey grouped in categories such as gender, age, urban and rural areas, education level, occupation, analysis of lipid levels and hyperlipidemia distribution. Multivariate Logistic regression analysis and principal component analysis method to filter the related factors of hyperlipidemia. Results: The average Chongqing surveyed in the elderly population lipids: TG 1.16 ± 0.68mmol / L, TC 4.02 ± 0.94mmol / L, HDL-C 1.39 ± 0.34mmol / L. Of this study was to investigate the elderly 976, of which 225 were suffering from hyperlipidemia, hyperlipidemia prevalence rate of 23.1%, one exception, there were 190 people, accounting for 84.0%, double abnormal 34 people, accounting for 15.6%, three exceptions only one, accounting for 0.4%. 2002 45 to 59 years and ≥ 60-year-old crowd hyperlipidemia prevalence rates were 22.9% and 23.4%, Chongqing investigation in the elderly population hyperlipidemia prevalence and the prevalence of close. Hyperlipidemia prevalence rate increased with increasing age in men than women, higher in urban than in rural areas. Patients with hyperlipidemia vegetables, fruits, fish and shrimp, milk and beans intake were lower than the recommended amount of balanced diet pagoda, livestock and poultry meat and fats and oils intake higher than the recommended amount. Logistic regression analysis and principal component analysis showed that family history, body mass index, smoking, alcohol consumption, vegetables, fruits, livestock and poultry meat and fats and oils are the main factors affecting the prevalence of hyperlipidemia. Conclusion: The findings of Chongqing Municipality in the elderly population lipid levels and prevalence of hyperlipidemia representative data. Lifestyle factors such as family history of hyperlipidemia, body mass index, smoking, drinking, and insufficient intake of vegetables, fruits, fish, beans and dairy, livestock and poultry meat and excessive intake of fats and oils, and other long-term dietary structure is irrational is an important risk factor prevalence of hyperlipidemia. Appropriate health education should focus on the characteristics of the structure of dietary, improve the level of nutrition knowledge, correct bad dietary habits, improve diet structure, integrated control from a number of factors, to reduce the incidence of hyperlipidemia.
