健步走对北京市昌平区职业人群身体成分及血压的干预效果研究

Study on intervention effect of walking on body composition and blood pressure of occupational population in Changping District of Beijing

目的了解"健步走"对北京市昌平区职业人群身体健康指标的干预效果,为昌平区职业人群慢性病防治工作提供依据。方法以参加2018年"万步有约"健走活动的在职职工为研究对象,采用清华同方体测仪(BCA-1C)、血压计和腰围尺等测量工具,在健步走前、健步走100天后分别进行2次体格测量并收集数据。结果健步走100天后628名研究对象万步率均≥90%,其中男性190人,女性438人。体重、体质指数(BMI)、体脂肪率、脂肪、内脏脂肪指数、腰围、臀围、腰臀比、收缩压、生理年龄10项指标均较健走前有所下降,差异均有统计学意义(均P<0.05)。30~39、40~49及50~59岁研究对象体重、BMI、体脂肪率、脂肪、内脏脂肪指数、腰围、臀围、收缩压、生理年龄9项指标均较健走前明显下降,差异均有统计学意义(均P<0.05)。男性体重、BMI、体脂肪率、脂肪、内脏脂肪指数、腰围、臀围、收缩压、生理年龄9项指标均较健走前明显下降,差异有统计学意义(P<0.05),但腰臀比及舒张压在健走前后差异均无统计学意义(均P>0.05)。女性舒张压在健走前后差异无统计学意义(P>0.05),其余10项指标健走后均较健走前明显下降(均P<0.01)。结论"健步走"对北京市昌平区职业人群身体健康指标的干预效果较明显。健步走后,体重、BMI、体脂肪率、脂肪、内脏脂肪指数、腰围、臀围、腰臀比、收缩压、生理年龄等指标均有明显改善,为北京市昌平区职业人群慢性病防治工作提供了科学依据。

Objective To understand intervention effect of walking on health indicators of occupational population in Changping District of Beijing, provide evidence for the development of the prevention and control measures for occupational population.Methods The occupational people who participated in the "ten thousand-step walk competition" in 2018 were selected to take twice physical examinations before and after 100 days’ walking by measurement tools including Tsinghua Tong Fang body measuring instrument(BCA-1 C), sphygmomanometer and waistline ruler, and the data were collected. Results After 100 days’ walking, the 10 000-step rate of 628 subjects was greater than or equal to 90%. There were 190 males and 438 females. The body weight, body mass index(BMI), body fat rate, fat, visceral fat index, waist circumference, hip circumference,waist-hip ratio,systolic pressure and physiological age decreased as compared with before walk ing, and the differences were statistically significant(all P<0.05). The body weight, BMI, body fat rate, fat, visceral fat index, waist circumference, hip circumference,systolic blood pressure and physiological age decreased after walking among the subjects aged 30-39, 40-49 and 50-59 years,and the differences were statistically significant(all P<0.05). The body weight, BMI, body fat rate, fat, visceral fat ind ex,waist circumference, hip circumference, systolic pressure and physiological age decreased after walking in males, and the differences were statistically significant(all P<0.05), but there were no statistically significant differences in waist-hip ratio and diastolic blood pressure between before and after walking(both P>0.05). There was no statistically significant difference in the diastolic pressure in females between before and after walking(P>0.05), and other indexes decreased obviously after walking(P <0.01). Conclusion The "walking" can obviously improve the body indicators among occupational population in Changping District of Beijing. Walking can effectively improve the body weight, BMI, body fat rate, fat, visceral fat index, waist circumference, hip circumference, waist-hip ratio, systolic pressure and physiological age, and the study provides a scientific basis for the prevention and treatment of chronic diseases in the occupational population of Changping District in Beijing.
