          Objective To understand the physical health of primary and secondary school students in Shijiazhuang City, and provide data basis for exploring preventive measures.

          Methods A cross-sectional survey was conducted to study the nutritional status of children and adolescents among students from 24 primary and secondary schools in 6 districts, 3 counties and 2 county-level cities of Shijiazhuang City during 2014-2017.

          Results From 2014 to 2017, the total 102 820 students that were effective medical examination number in primary and middle schools in Shijiazhuang City were enrolled into this study. There were 51 370 male students and 51 450 female students. The height of male students was (161.66±16.90) cm, the weight was (55.81±18.73) kg; the height of female students was (156.00±13.03) cm, and the weight was (49.72±13.87) kg. The total detection rate of malnutrition among primary and middle school students in Shijiazhuang City was 5.85%, the total overweight rate was 16.24%, and the total obesity rate was 12.55% during 2014-2017. The detection rate of malnutrition in boys (7.06%) was significantly higher than that in girls (4.66%)( P<0.001). The detection rate of overweight and obesity among boys was also significantly higher than that of girls ( P<0.001). The overweight and obesity of primary and middle school students in Shijiazhuang City increased from 2014 to 2017 ( P<0.05). Among the three sections from primary school to high school, primary school students had the worst nutritional status, and the detection rates of malnutrition, overweight and obesity were the highest (all P<0.05). There was a statistically significant difference in the detection rate of malnutrition between different segments ( P<0.001). The detection rates of severe wasting, mild wasting and growth retardation were consistent with the detection rate of malnutrition (all P<0.001). After the trend test of χ 2, the rates of overweight and obesity showed a decreasing trend with grades (all P<0.001).

          Conclusion The situation of malnutrition and overweight and obesity prevention and control in primary and middle school students in Shijiazhuang City is still grim. The prevention and control of the nutritional status of boys and primary school students should be emphasized.
