The Study Of Chronic Diseases And Dietary Status Of The Residents In Qilihe Lanzhou

Objectives: By investigating the overall health and nutrition status between urban and rural areas, different gender and age groups residents in Qilihe.(1) To evaluate the prevalence of Non-communicable disease (NCD), such as Hypertension, Diabetes mellitus and Dyslipidemia, then analyze the related living-behavior risk factors of chronic diseases.(2) To learn their dietary nutrition status, which include nutrients intake and dietary structure; and analyze the correlation between dietary structure and Non-communicable diseases.(3) The results so as to provide the reference on developing appropriate intervention strategies for NCD control and prevention.Methods: The project was developed from April to December2012. By using cross-sectional study to learn the NCD prevalence and dietary status of permanent residents in9streets,4towns and2townships of Qilihe; Questionnaires, physical examination, laboratory testing and dietary survey methods were adopted in the survey; Questionnaires were carried out by interviewing. Height, weight and blood pressure data were collected for physical examination; Dietary intake was reflected on the food frequency questionnaires. The Binary Logistic regression analysis was used to evaluate the correlated risk factors of hypertension/Diabetes mellitus and dyslipidemia of Qilihe residents.Results:(1) The results of research showed that the chronic disease prevalence was fairly high among the residents. Hypertension incidence of residents23.64%, the crowd urban incidence was higher than crowd rural (P<0.05), which were24.95%and21.37%; there was no significant difference between male and female. Diabetes prevalence rate was6.36%, urban prevalence rate is higher than rural, which are7.14%and5.15%; incidents in male is higher than in female, which are7.09%and5.94%. Dyslipidemia incidents28.24%, and urban prevalence was28.07%, the rural was28.58%; Male23.53%, female29.89%. These three chronic diseases incidents were increasing with aging (P<0.05).The unconditional multivariable Logistic regression analysis showed that the incidents of hypertension, diabetes and dyslipidemia were strongly associated with risk of age, obesity, psychological stress, central obesity (OR>1); yet, drinking was similarly affected hypertension. While, regular exercise and psychological health have positive effect on it (OR<1). (2) Dietary survey showed that daily cereal consumption276.31g per person, dairy, meats daily consumption89.60g; Milk, egg and soy products were totally123.40g; Vegetables and fruits intake were insufficient obviously, which were244.73g per day,58.24g. Residents had an excessive salt and cooking oil intake, they were9.47g and34.36g. Nutrients and energy intake: protein energize was higher than recommended; average daily energy intake was1900.83Kcal, which lower than the recommended values; the intake of Vitamin A and Vitamin E excessed more120%than recommended intake; dietary fiber, vitamin B6and Vitamin B12intake enough, Vitamin B1and B2intake were insufficient. Calcium and Magnesium daily intake of every person were602.76mg and275.50mg, and insufficient for a person; while, Sodium intakes at a high level, and more169.42%than recommended; the intake of Iron and Potassium were adequate.(3) Dietary influence on chronic disease analysis showed that: carbohydrate energy increasing had a certain protective effect on dyslipidemia but negative effect on obesity; the increasing of fat intake was associated with increasing of hypertension and obesity incidence; adequate dietary fiber intake may help to decrease the incidence of chronic diseases.Conclusions:(1) According to the survey, the incidence of chronic diseases in Qilihe district is at a high level, which compared to the national incidence of chronic diseases2002; the major risk factor of disease were age, drinking, overweight/obesity, unhealthy emotions and lack of exercising.(2) the main nutritional problems is unreasonable dietary structure lead to the lack of calcium magnesium, B vitamins and overfeeding of sodium, Vitamin A and Vitamin E such micronutrients.(3) The chronic incidence in different carbohydrates and fat energize groups is different obviously; Increasing fiber intake would obviously decreasing the chronic diseases incidence.(4) It’s necessary to carry out the healthy living behavior and nutritional interventions, and more focus on the population of male, aged56years and above, overweight/obesity, unreasonable diet structure, to control and prevent chronic diseases prevalence.
