ABSTRACT
Objective@#To analyze the trend of overweight and obesity among Han students aged 7-18 years in Ningxia from 2000 to 2014, and to provide scientific basis for child and adolescent obesity prevention and control in Ningxia.@*Methods@#Based on data of the height and weight of Han students aged 7-18 in the four waves of national student physical surveys in Ningxia from 2000 to 2014, SPSS 21.0 was used for trend analysis.@*Results@#From 2000 to 2014, the overweight and obesity rate of Han students in Ningxia from 7 to 18 years old showed an upward trend. Compared with the year of 2000, the total overweight rate increased by 2.06 times in 2014 and the obesity rate increased by 4.40 times. The overweight and obesity rate of boys was higher than that of girls in 2005 and 2014, and the difference was statistically significant(χ2=4.91, 6.20, P<0.05). The overweight and obesity rates of urban students were higher than those of rural students in 2005 and 2010(χ2=9.63, 5.97, P<0.05). The correlation analysis between the overweight and obesity rate of Ningxia students and socioeconomic indicators showed that the overweight and obesity of Ningxia students from 2000 to 2014 was closely related to the level of Ningxia socioeconomic development, especially the obesity detection rate of rural students was related to Ningxia’s GDP and The correlation between GDP, per capita disposable income, per capita consumption expenditure, and urbanization rate is stronger(r=0.98, 0.98, 0.99, 1.00, 0.93, P<0.05).@*Conclusion@#Socioeconomic of Ningxia is rapidly increasing, and the overweight and obesity rate of Han students aged 7 to 18 is also increasing. It is suggested that society, schools and parents should pay great attention to this phenomenon, build community-wide efforts to prevent childhood obesity, and prevent chronic diseases caused by overweight and obesity occurrence risk.
