目的掌握傣族学生身体机能状况及发展趋势,为制订有关干预措施提供依据。方法按照《2005年全国学生体质健康调研工作手册》要求进行。结果⑴傣族学生的脉搏随年龄增长,安静脉搏逐渐减慢。⑵收缩压和舒张压均在正常值范围内波动,男生收缩压和舒张压随年龄的增长呈上升趋势,女生7~15岁呈增长趋势,16~18岁略有下降。⑶肺活量存在性别差异,男生各年龄段肺活量均值均高于女生,差别有统计学意义,无女高男低的交叉现象。⑷各年龄段男生肺活量/体质量指数均高于女生,二者差异有统计学意义。结论(1)脉搏、收缩压和舒张压3项指标与2000年相比,调查结果基本一致;(2)2000~2005年的5年间,7~18岁各年组傣族学生的肺活量均有不同程度的下降,男生平均下降417.6 mL,女生平均下降355.9 mL:肺活量/体质量指数男生平均下降12.4 mL/kg,女生平均下降11.2 mL/kg。其原因可能是学习负担过重,体育锻炼时间相对较少、质量不够高等因素有关。
Objective To grasp the physical condition and development trend of Dai students and provide the basis for making relevant interventions. Methods in accordance with the “2005 National Student Health Survey research manual” requirements. Results ⑴ Dai students pulse with age, quiet pulse gradually slowed down. (2) Both systolic and diastolic blood pressure fluctuated within the normal range. Systolic blood pressure and diastolic blood pressure of boys increased with age. The female students showed an increasing trend from 7 to 15 years of age and a slight decrease from 16 to 18 years of age. ⑶ gender differences in vital capacity, male students of all ages mean lung capacity were higher than girls, the difference was statistically significant, no cross of high and low male phenomenon. (4) The boys’ vital capacity / body mass index in all ages were higher than girls, the difference was statistically significant. Conclusions (1) The three indexes of pulse, systolic pressure and diastolic blood pressure are basically the same as those of 2000. (2) In the five years from 2000 to 2005, the students of all ages from 7 to 18 years old had different vital capacity The average drop of male students was 417.6 mL and that of female students was 355.9 mL on average: the boys’ average life expectancy decreased by 12.4 mL / kg and the average female students decreased by 11.2 mL / kg. The reason may be overburdened learning, physical exercise time is relatively small, the quality is not high enough factors.
