武陵山区流动儿童和城区常住儿童身体机能的比较

目的:了解湘西少数民族地区流动儿童的身体机能发育状况,为流动儿童的生长发育提供帮助。方法:随机抽取湘西少数民族地区9～12岁流动儿童500名,城区常住儿童500名,分别测试其身体机能指标。结果:9岁男女儿童中除心率以外,其他指标两组均有统计学差异。10岁男女儿童中,男性身高、体重、基础代谢率、身体脂肪率、肺活量等指标均有明显差异,而BMI、心率无统计学差异。女性儿童中各项指标均有统计学差异。11岁男女儿童中,身高、体重、BMI、基础代谢率、身体脂肪率、肺活量等指标,城区常住儿童均高于流动儿童(P<0.05),而心率无统计学差异。12岁儿童中,男性的体重、BMI、身体脂肪率等指标有统计学差异,其他指标无统计学差异。女性儿童中身高、体重、BMI、基础代谢率、身体脂肪率肺活量有统计学差异。结论:城区常住儿童身体机能指标优于流动儿童。

Comparison of physical functions of migrant children in Wuling mountainous area and resident children in urban area

Objective: To understand the development status of physical function of the migrant children in the areas inhabited by the minority nationalities in western Hu’nan province,offer help for growth and development of migrant children. Methods: Five hundred 9-12-year-old migrant children in the areas inhabited by the minority nationalities in western Hu’nan province and five hundred resident children in urban area were selected randomly,then the indexes of physical function were measured respectively. Results: Among the children aged nine years old,there was statistically significant difference in the indexes of boys and girls except heart rate between the two groups.Among the children aged ten years old,there was statistically significant difference in the body height,body weight,basal metabolic rate,the percentage of body fat,and vital capacity of boys between the two groups,but there was no statistically significant difference in body mass index(BMI) and heart rate;there was statistically significant difference in the indexes of girls between the two groups.Among the children aged eleven years old,the body height,body height,BMI,basal metabolic rate,the percentage of body fat,and vital capacity of the resident children in urban area were significantly higher than those of the migrant children(P<0.05),but there was no statistically significant difference in heart rate.Among the children aged twelve years old,there was statistically significant difference in body weight,BMI,and the percentage of body fat of boys between the two groups,there was no statistically significant difference in the other indexes of boys between the two groups;there was statistically significant difference in body height,body weight,BMI,basal metabolic rate,the percentage of body fat,and vital capacity of girls between the two groups. Conclusion: The indexes of physical function of the resident children in urban area are better than those of the migrant children.
