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。
Objective: To understand the physical and mental development of migrant children in minority areas of western Hunan and provide help for the growth and development of migrant children. Methods: 500 randomly selected children from 9 to 12 years old in Xiangxi minority area and 500 children in urban area were randomly selected to test their body function indexes. Results: In addition to heart rate in 9-year-old boys and girls, other indicators were statistically significant differences between the two groups. Among 10-year-old boys and girls, there were significant differences in body height, body weight, basal metabolic rate, body fat rate, vital capacity and other indicators. However, there was no significant difference in BMI and heart rate. The indicators of female children have statistical difference. Eleven-year-old boys and girls, height, weight, BMI, basal metabolic rate, body fat rate, vital capacity and other indicators of urban resident children were higher than those of floating children (P <0.05), but no significant difference in heart rate. Among 12-year-old children, there were significant differences in body weight, BMI, body fat percentage among other indicators, but no significant difference in other indicators. Female children height, weight, BMI, basal metabolic rate, body fat rate of vital capacity was statistically different. Conclusion: The physical performance of resident children in urban areas is better than that of floating children.
