摘　　要：目的分析初中生体质指数(BMI)与肺活量之间的关联性,为有效预防初中生肥胖提供参考。方法采取整群抽样方法,选择佳木斯市12所初中12~14岁学生,按照2014年全国学生体质健康调研工作手册的要求进行身高、体质量和肺活量测量。结果佳木斯市初中生肺活量与BMI在总体、消瘦、正常体质量、体质量超标、肥胖等级均呈正相关,男生秩相关系数分别为0.276、0.293、0.256、0.229、0.227(P值均<0.01);女生秩相关系数分别为0.228、0.226、0.230、0.138、0.135(P值均<0.01)。男、女生BMI与肺活量体质指数呈负相关,秩相关系数分别为-0.515和-0.475(P值均<0.01)。结论佳木斯市初中生BMI呈偏态分布,多数学生处于正常范围,存在一定数量体质量超标和肥胖学生。初中生BMI不同等级与肺活量均呈正相关,BMI与肺活量体质指数呈现负相关。非正常体质量在一定程度上影响机体健康状况,学校应在饮食行为、体育锻炼、生活习惯等方面开展健康教育和健康促进,促使学生达到国家体质健康标准。Objective To determine the association between body mass index（BMI） and vital capacity in junior high school students, so as to provide the reference for the effective prevention of obesity of students. Methods The students aged12 to 14 years in 12 junior high schools in Jiamusi City were selected by the cluster sampling method to measure their body height, weight and lung capacity according to the requirements of the 2014 national student physical fitness survey manual.Results The BMI and vital capacity of the junior high school students in Jiamusi City were positively correlated to the general, thin, normal weight, overweight and obesity. The rank correlation coefficients of boys were 0.276, 0.293, 0.256, 0.229 and0.227 respectively, and all the P values were less than 0.01. The coefficients of girls were 0.228, 0.226, 0.230, 0.138 and0.135 respectively, and all the P values were less than 0.01. The BMI and vital capacity weight index of boys and girls were negatively correlated. The rank correlation coefficients of boys and girls were-0.515 and-0.475 respectively, and both P values were less than 0.01.Conclusion The BMI of junior high school students in Jiamusi City presents a skew distribution.Most students are in the normal range, but there are a certain number of overweight and obese students. The BMI and vital capacity of the students are positively correlated in different grades, but BMI is negatively correlated with the vital capacity weight index. The abnormal weight affects the health of the body to some extent. The school authorities should carry out the health education and health promotion in the aspects of diet behavior, physical exercises, life habit and so on, so as to promote the students to meet the national physical fitness standard.
