目的了解高青县中小学生营养状况,为开展学生营养卫生工作提供科学依据。方法 2012年按《山东省中小学生健康体检方法》对高青县53所中小学校的学生进行健康体检,采用《中国学生7~22岁身高标准体重值》对体检结果进行分析。结果高青县30 676名学生中小学、初中、高中的营养不良检出率分别为6.17%、7.08%、4.04%(P<0.01);肥胖率分别为13.90%、14.86%、10.03%(P<0.05);超重率分别为5.35%、5.35%、5.42%(P>0.05)。营养不良男生474人,占5.53%;女生573人,占6.82%(P<0.01)。初、高中学生男生超重率高于女生(P<0.01),小学生男女生超重率无差异(P>0.05)。小学、高中学生男生肥胖率高于女生(P<0.01),初中生男女生肥胖率差异无统计学意义(P>0.05)。结论高青县中小学生营养不良和营养过剩同时存在,以营养过剩问题较为突出。
Objective To understand the nutritional status of primary and secondary school students in Gaoqing County and provide a scientific basis for their nutrition and hygiene work. Methods In 2012, the health examination of 53 primary and secondary school students in Gaqing County was conducted according to “Healthy Examination Method of Primary and Middle School Students in Shandong Province”.

Results The prevalence of malnutrition in primary and middle school, middle school and high school among 30 676 students in Gaoqing County was 6.17%, 7.08% and 4.04% respectively (P <0.01). The obesity rates were 13.90%, 14.86% and 10.03% respectively <0.05). The rates of overweight were 5.35%, 5.35% and 5.42% respectively (P> 0.05). Malnourished 474 boys, accounting for 5.53%; girls 573, accounting for 6.82% (P <0.01). The prevalence of overweight was significantly higher in boys than girls in primary and middle school (P <0.01). There was no difference in overweight among boys and girls in primary school (P> 0.05). The prevalence of obesity in primary school and high school students was higher than that of female students (P <0.01). There was no significant difference in the obesity rate among junior high school students (P> 0.05).
