Change of dietary pattern among young people aged 18-35 in China from 1989 to 2018
OBJECTIVE To analyze the dietary patterns changes of young people aged 18-35 in 15 provinces(autonomous regions,municipalities)from 1989 to 2018.METHODS Using the data of China Health and Nutrition Survey,a total of 25 400 young people aged 18-35 with complete dietary and sociodemographic information from 1989 to 2018 in 15 provinces(autonomous regions,municipalities)were selected as the research objects.Nutrition survey was carried out by using 3 consecutive days of 24-hour review method combined with weighing accounting method.Energy and nutrient intake was calculated based on food composition list.The principal component cluster analysis was used to select food groups and K-mean cluster was uesd to extract dietary patterns.Dwass-Steel-Critchlow-Fligner was used to test the difference of food intake in different dietary patterns.Cochran-Armitage trend test was to analyze the change of dietary patterns with the years.Chi-square test was to analyze the difference of people with different dietary patterns in 2018.RESULTS The dietary patterns of young people aged 18-35 in 15 provinces(autonomous regions,municipalities)were mainly divided into three categories:"traditional rice","traditional pasta"and"high-quality protein".In 2018,the proportion of"traditional rice"dietary patterns was higher for men than for women,and the proportion of"high-quality protein"dietary patterns was lower than for women.The proportion of"traditional pasta"dietary pattern in people aged 25-35 was higher than that aged 18-24,and the proportion of"high-quality protein"dietary pattern was lower than that aged 18-24.The proportion of people in urban with"traditional rice"dietary pattern was lower than that in rural areas,and the proportion of"high-quality protein"dietary pattern was higher than that in rural areas.The northern region was dominated by"traditional pasta"dietary pattern,while the southern region was dominated by"traditional rice"dietary pattern,and the proportion of people with"high-quality protein"dietary pattern was higher in the northern region than in the southern region.With the increase of education level and income level,the proportion of people with"high-quality protein"dietary pattern showed an increasing trend.From 1989 to 2018,the"traditional rice"dietary pattern had always maintained a high proportion among young people aged 18-35 in 15 provinces(autonomous regions,municipalities)in China,and the"traditional pasta"dietary pattern had been decreasing since 2009,and the"high-quality protein"dietary pattern had significantly increased since 2011.CONCLUSION From 1989 to 2018,the proportion of young people aged 18-35 with reasonable dietary pattern has increased in 15 provinces(autonomous regions,municipalities),but the traditional dietary pattern still needs to be improved.
