To assess the level of physical activity in public school teachers.
Cross-sectional study conducted with 1,681 teachers from the city of São Paulo, southeastern Brazil, in 2009. The International Physical Activity Questionnaire short version was applied and the level of physical activity was categorized as low, moderate or high. The study sample was stratified by age, gender and area of the city (south and east). The chi-square test was used for comparisons at a 5% level of significance.
The prevalence of low, moderate and high levels of physical activity was 46.3%, 42.7% and 11%, respectively. Low physical activity was more prevalent among those aged 31 to 42 years (19.5%) and less prevalent among those aged 55 to 66 (5.7%). Moderate and high levels of physical activity were less prevalent among older teachers. A greater proportion of teachers showed low and high levels of physical activity in the east compared to the south of the city (50.5% vs. 48.6%; 11.4% vs. 8.1%, respectively). The proportion of teachers reporting moderate physical activity was significantly lower in the east (38.1%) compared to the south of the city (43.3%). Low and high levels of physical activity were significantly higher in men than women (53% vs. 42.9%; 14.1% vs. 9.4%, respectively). The prevalence of moderate level of physical activity was significantly lower in men (32.9%) than women (47.7%).
The prevalence of low physical activity was strikingly high. Variables such as age, gender and city area should be taken into account while planning and targeting campaigns aimed at promoting increased physical activity in this population.
评估公立学校教师的身体活动水平。
2009 年,在巴西东南部城市圣保罗对 1681 名教师进行了横断面研究。应用国际体力活动问卷短版,并将体力活动水平分为低、中、高三个等级。根据年龄、性别和城市区域(南部和东部)对研究样本进行分层。采用卡方检验,以 5%的显著性水平进行比较。
低、中、高强度体力活动的流行率分别为 46.3%、42.7%和 11%。31 至 42 岁年龄组体力活动水平较低(19.5%),55 至 66 岁年龄组体力活动水平较低(5.7%)。年龄较大的教师体力活动水平较低和较高的比例较低。与南部相比,东部地区低和高强度体力活动的教师比例更高(分别为 50.5%对 48.6%;11.4%对 8.1%)。与南部相比,东部地区报告中等体力活动的教师比例明显较低(38.1%对 43.3%)。男性低和高强度体力活动的比例明显高于女性(分别为 53%对 42.9%;14.1%对 9.4%)。男性中等体力活动的流行率明显低于女性(32.9%对 47.7%)。
低体力活动的流行率非常高。在规划和针对该人群开展增加体力活动的运动时,应考虑年龄、性别和城市区域等变量。
