Abstract
To study the longitudinal transition of dietary patterns among residents in one of the richer provinces in China, Jiangsu Province from 1989 to 2009, we used a subpopulation of adults aged 18 and older in 6 cities and counties from China Health and Nutrition Survey. Experienced physicians collected detailed dietary data by weighing method in combination with 3 consecutive 24‐hour recalls. All statistical analyses were conducted using SAS version 8.0. There were a decrease in the consumption of grain and a significant increase in animal foods. While energy and protein met the Chinese national Reference Nutrient Intake (RNI), there were marked changes in fat intake and a rapid increase in the consumption of dairy products and the proportion of energy intake from fat, mainly from vegetable oils. A reduction of the gaps in calcium intake below the Chinese RNI occurred. The prevalence of overweight and obesity (BMI≥24) among men increased almost fivefold from 9.4% in 1989 to 41.1% in 2009, with an acceleration in the annual prevalence level increase over the past decade. Hypertension over this period grew from 7.8% in men and 4.8% in women to 37.6% and 30.8% respectively in 2009. The dietary transition in Jiangsu has seen a marked shift in the sources of calories with a marked increase of dietary fat. Overweight, obesity and hypertension are increasingly prevalent.This study was supported by NIH (R01‐HD30880) and Fogarty International Center, NIH (5D43TW007709).
