目的了解深圳市龙岗区中心城小学生营养状况。方法对深圳市龙岗区中心城5所小学7～14岁在校学生进行身高、体重两项发育指标的测量,依据卫生部下发的身高标准体重值进行个体营养评价。结果被调查的6 339名学生中营养正常者占69.3%,营养不良者占17.0%,超重与肥胖者占13.6%。营养不良以轻、中度为主,占97.8%(1 054/1 078)。各年级的营养不良率随年级的升高而上升,超重与肥胖率则无明显差异。总体营养不良率女生(22.6%)显著高于男生(12.3%)(χ2=116.81,P<0.01);超重或肥胖率男生(17.4%)显著高于女生(9.2%)(χ2=89.48,P<0.01)。结论相对其他地区,深圳市龙岗区中心城小学生营养不良情况仍较严重,学生的营养和健康工作应得到龙岗区儿童少年保健机构、教育管理部门、学校、家长等有关方面的关注和支持。
Objective To understand the nutritional status of primary school students in Longgang District of Shenzhen City. Methods The height and weight of two school children aged from 7 to 14 in 5 primary schools in Longgang District of Shenzhen City were measured. According to the height standard body weight value issued by the Ministry of Health, individual nutrition evaluation was made. Results Among the 6 339 students surveyed, 69.3% were malnourished, 17.0% were malnourished, and 13.6% were overweight and obese. Malnutrition was mild and moderate, accounting for 97.8% (1 054/1 078). The rate of malnutrition in all grades increased with the increase of grade, while there was no significant difference between the rate of overweight and obesity. The prevalence of malnutrition in girls (22.6%) was significantly higher than that of boys (12.3%) (χ2 = 116.81, P <0.01); that of overweight or obesity boys was significantly higher than that of girls (9.2%) (χ2 = 89.48, P <0.01). Conclusion Compared with other regions, the malnutrition among primary school students in the central city of Longgang District is still serious. Students’ nutrition and health work should receive the attention and support from the children and adolescents health care institutions, education and management departments, schools and parents in Longgang District.
