Trends of eating out among males in China and its correlation with nutrition and health during 2000 to 2018
OBJECTIVE To analyze the trend of eating out among Chinese male adults and explore the association between eating out and dietary nutrition and health.METHODS Males aged 18 and above with complete data were selected from China Health and Nutrition Survey 2000,2004,2006,2009,2011,2015 and 2018.Eating out behavior was defined as having consumption of food prepared outside the home during the three consecutive 24-h dietary recalls period.Cochran-Armitage trend test was used to analyze the trend of prevalence of eating out and the energy contribution from eating out foods in males from 2000 to 2018.Analysis of covariance was used to compare the differences in several food and dietary nutrient intakes and nutritional indicators by eating out in 2018.RESULTS The prevalence of eating out among Chinese male adults increased from 48.49％in 2000 to 57.51％in 2018,showing an increased trend followed by a decreased trend.Males in the 18-29 years old group,urban group,high income group,and high education level group had a higher rate of eating out(P＜0.05).The energy contribution from eating out foods increased from 21.80％in 2000 to 28.77％in 2018,showing a slow upward trend.In 2018,the intake of rice,tubers and vegetables was lower in the eating out group,while intake of wheat,fruits,livestock and poultry meat,aquatic products,eggs and milk in eating out group was higher than those in the non-eating out group(P＜0.05).The eating out group had a higher intake of energy,fat,protein,cholesterol,calcium,zinc,vitamin B,and vitamin B2 than the non-eating out group(P＜0.05).The eating out group had lower levels of systolic blood pressure,HDL-C,blood glucose and glycosylated hemoglobin than the counterparts.The levels of BMI,waist,body fat percentage,diastolic blood pressure and TG were higher in the eating out group than in the non-eating out group.CONCLUSION From 2000 to 2011,the eating out rate of males in China showed an upward trend,and a downward trend after 2011.At the same time,the energy contribution of eating out foods is increasing.Eating out was associated with major food and nutrients intake and indicators of nutritional status in male adults.
