Association between dietary patterns and metabolic syndrome among elderly people in Zhejiang province

Abstract

Objective To understand the relationship between the dietary patterns and metabolic syndrome among elderly people in Zhejiang province, in order to provide scientific basis and reference for nutrition interventions. Methods Data were obtained from the 2010-2012 Chinese National Nutrition and Health Survey, and factor analysis was used to obtain food patterns among elderly people in Zhejiang province. The Logistic regression was used to explore the association of the food patterns with metabolic syndrome and its components. Results The intakes of bean products, nuts, fruits, eggs, and milk in elderly people were generally low, and the intakes of livestock and poultry meat, cooking oil and salt were relatively high. 5 dietary patterns were derived by factor analysis: high-quality protein diet, mediterranean diet, condiments diet, traditional dietary pattern and western dietary pattern. The medical test results in 780 elderly people showed that the standardized prevalence of metabolic syndrome in the elderly was 28.8%, standardized central obesity rate was 41.2%, standardized hypertension rate was 50.3% and standardized hyperglycemia rate was 39.5%. Logistic regression analysis showed that different dietary patterns had different effects on the metabolic syndrome and its components. Conclusions The prevalence rate of metabolic syndrome and the abnormal rates of its components are high in the elderly in Zhejiang. The intakes of fruits and milk are generally low, and intakes of livestock and poultry meat, cooking oil and salt are relatively high. The relationship between dietary patterns and MS or its components is complicated, so it is necessary to guide the elderly people to adopt reasonable diet by referring to the Diet Pagoda in order to reduce the risk of MS or its components.
