[Abstract]:Objective to investigate the dietary nutrition status of adolescents in Guiyang city and rural areas, and to reflect the regional differences of dietary nutrition status. Methods A total of 1080 junior middle school students in Guiyang city and rural areas were investigated on dietary nutrition. The data of dietary intake for 3 consecutive days were collected by 24 h retrospective method. Height and weight were measured in the field. Results the intake of potato in Guiyang was reasonable (average daily intake was 290.00g ~ 351.94 g / d), legumes in urban area (19.60 ~ 21.00 g / d) and milk (139.75 ~ 152.08 g / d) were lower than that in urban area. The intake of milk, vegetables, fruits and other foods in rural areas was lower than the recommended values, and the energy intake (average daily intake of 2 040.96) and protein (average daily intake of 47.62% 75.12 g) in the two areas were lower than the recommended values, and the energy distribution of the three meals in the two areas was not reasonable. The nutritional status of urban areas is better than that of rural areas. The normal nutritional status of urban areas is 69%, while that of rural areas is 52%. Conclusion the dietary structure of adolescents in Guiyang is still to be improved, and nutrition education for adolescents and parents should be strengthened. Especially in rural areas, students should be instructed to improve their poor eating habits and to balance the intake of all kinds of foods.
