健走活动对职业人群健康的影响

The Impact of Walking Activities on the Health of Occupational Groups

目的研究健走活动对职业人群健康的影响。方法选取天津市滨海示范区机关事业单位参加首届"万步有约"健走干预项目的职工作为研究对象,收集性别、年龄、体重、腰围、身高、体脂肪率、内脏指数和血压等资料,比较健走前后各项指标的差异。结果共纳入120人,其中男性70人,占58.33%;女性50人,占41.67%;年龄23～58岁,平均年龄(37.27±5.12)岁。健走后职工平均体重、腰围、BMI、体脂率、内脏指数和血压值均较健走前降低(P<0.05)。健走后男女职工的腰围、BMI、内脏指数和血压与健走前相比,都有不同程度的下降(P<0.05);男女职工腰围、BMI和血压存在时间交互作用(P<0.05),且男职工健走后的下降幅度大于女职工(均P<0.05);男女职工内脏指数随时间变化的差异均无统计学意义(P>0.05)。不同年龄段职工的腰围、内脏指数、收缩压和舒张压存在时间交互作用(P<0.05),而BMI不存在时间交互作用(P>0.05)。结论健步活动可改善职业人群腰围、血压等指标,且发现男性、中老年职工的体质指标改善效果更明显。

Objective To study the effects of walking activities on the health of occupational groups.Methods The employees of the Tianjin Binhai Demonstration Zone institutions and institutions participated in the first "ten thousand steps agreement" walking intervention project, and collected data on gender, age, weight, waist circumference, height, body fat percentage, visceral index and blood pressure. Compare the differences between the indicators before and after walking.Results A total of 120 people were included, including 70 males, accounting for 58.33%;50 females, accounting for 41.67%;aged 23-58 years, mean age (37.27±5.12) years old. After walking, the average body weight, waist circumference, BMI, body fat percentage, visceral index and blood pressure were lower than those before walking (P<0.05). After walking, the waist circumference, BMI, visceral index and blood pressure of male and female workers were decreased in different degrees compared with those before walking (P<0.05). There was a time interaction between waist circumference, BMI and blood pressure of male and female workers (P<0.05). The decline of male workers after walking was greater than that of female employees (P<0.05);there was no significant difference in the visceral index of male and female workers with time (P>0.05). There were time interactions between waist circumference, visceral index, systolic blood pressure and diastolic blood pressure of workers of different ages (P<0.05), but there was no time interaction of BMI (P>0.05).Conclusion The exercise activity can improve the waist circumference and blood pressure of the occupational population, and it is found that the improvement effect of the physical indicators of male and middle-aged workers is more obvious.
