Abstract: ObjectiveTo evaluate the effect of lifestyle intervention to dietary intake among high risk group of non-communicable diseases (NCDs).MethodsTwelve communities were randomly selected from Futian District, Shenzhen City from October to November 2013, and high risk group of NCDs were screened from the selected communities. High risk group of NCDs were divided into intervention group and control group for 2-year follow-up. The intervention group received group-based health education activities and lifestyle intervention, while the control group did not take any active intervention activities. The changes of dietary intake were evaluated among high risk group of NCDs with intact dietary data before and after the intervention. ResultsA total of 1 211 subjects (769 in the intervention group, 442 in the control group) were included. The mean age of the intervention group was (53.66±11.35) years old and the control group (57.65±12.42) years old (P<0.01). In the intervention group, 59.30% were female, 93.76% married, and 98.83% the Han nationality; in the control group, 57.47 % were female, 92.99 % married, and 99.10 % the Han nationality. The number of high-risk factors was mainly 1 to 2, which was 84.66% in the intervention group and 77.38% in the control group. After controlling for confounding factors, subject average intakes of cereal and tubers, aquatic products, milk and dairy products, vegetables, and soybean and nuts in the intervention group increased by 40.15, 48.14, 23.38, 35.01 and 12.19 g/d (P＜0.05 or P＜0.01) , respectively, after 2-year follow-up and intervention. Before and after intervention, the distributions of daily dietary intakes of cereal and tubers, aquatic product, vegetable, fruit, soybean and nuts were significant in the intervention group (all P < 0.01) and the distributions of daily dietary intakes of cereal and tubers, soybean and nuts, aquatic products and eggs in the control group (P < 0.05 or P < 0.01). ConclusionTargeted interventions can improve the quality of some kinds of food intake for high risk group of NCDs.
