背景:缺乏体力活动是一个全球性的健康问题,以便在全球范围内制定关于足够身体活动水平的建议,比如在巴西。然而,加拿大24小时运动指南在世界上首次考虑针对特定时间的体育锻炼建议,久坐的行为和睡眠,这仍然不是为拉丁美洲人口开发的。本研究旨在验证巴西内城对加拿大24小时指南的遵守情况,并分析其与社会人口统计学方面的关系。
方法:横断面流行病学研究,样本由250名成年人(140名女性)组成,平均年龄为41.0岁。通过加速度计收集了中度至剧烈的体育锻炼(MVPA)和久坐行为的客观测量。睡眠时间和社会人口统计学方面(种族,性别,年龄,教育程度和社会经济水平)是通过面对面问卷获得的。加拿大24小时指南考虑≥150分钟/周的MVPA,<8小时/天的久坐行为和7和9小时之间的每日睡眠时间,分别和组合进行分析。根据社会人口统计学变量的类别,使用具有稳健方差估计的泊松回归分析满足24小时指南的患病率比率(PR)。由IBMSPSS25.0版软件执行。
结果:只有24.4%的样本(n=61)符合完整的24小时指南。久坐行为是最符合的准则(88%),其次是MVPA(56.8%)和睡眠(53.2%),根据性别没有显著差异。与老年参与者相比,年轻组(18-39岁和40-59岁)的参与者更有可能符合MVPA指南(PR=2.51[95CI=1.47;4.28]和PR=2.60[95CI=1.52;4.45],分别),以及MVPA和久坐行为的组合(PR=1.98[95CI=1.13;3.44]和PR=2.17[95CI=1.25;3.79],分别)和睡眠指南的MVPA(PR=2.39[95CI=1.09;5.27]仅在18-39年组)。男性比女性更有可能符合MVPA指南(PR=1.29[95CI=1.04;1.59])。
结论:在巴西的一个小城市中,年轻的年龄和男性成年人更有可能符合加拿大的24小时指南。然而,仍需要对更大和有代表性的社会人口统计学阶层样本进行进一步研究。
The physical inactivity is a global health concern, so that recommendations on sufficient physical activity levels are elaborated worldwide, such as in Brazil. However, the Canadian 24-Hour Movement Guidelines were first in the world to consider time-specific recommendations for physical activity, sedentary behavior and sleep, which is still not developed for Latin-American population. The present study aimed to verify the adherence to Canadian 24-hour guidelines in a Brazilian inner city and to analyze its association with sociodemographic aspects.
A cross-sectional epidemiological study, with a sample composed by 250 adults (140 women), with a median age of 41.0 years. Objective measures of moderate-to-vigorous physical activity (MVPA) and sedentary behavior were collected by accelerometry. Sleep duration and sociodemographic aspects (ethnicity, gender, age, educational attainment and socioeconomic level) were obtained through a face-to-face questionnaire. Canadian 24-hour guidelines considered ≥ 150 min/week of MVPA, <8 h/day of sedentary behavior and daily sleep time between 7 and 9 h, being analyzed separately and in combination. Poisson regression with robust variance estimator was used to analyze the prevalence ratio (PR) of meeting the 24-hour guidelines according to the categories of sociodemographic variables, being performed by the software IBM SPSS version 25.0.
The complete 24-hour
guidelines were met only by 24.4% of sample (n = 61). Sedentary behavior was the most met
guideline (88%), followed by MVPA (56.8%) and sleep (53.2%), without significant difference according to sex. When compared to elderly participants, those participants in younger groups (18-39 years and 40-59 years) were more likely to meet MVPA
guideline (PR = 2.51 [95%CI = 1.47; 4.28] and PR = 2.60 [95%CI = 1.52; 4.45], respectively), as well as the combination of MVPA and sedentary behavior (PR = 1.98 [95%CI = 1.13; 3.44] and PR = 2.17 [95%CI = 1.25; 3.79], respectively) and MVPA with the sleep
guideline (PR = 2.39 [95%CI = 1.09; 5.27] only for 18-39 years group). Men were more likely to meet MVPA
guideline than women (PR = 1.29 [95%CI = 1.04; 1.59]).
Younger aged and male adults were more likely to meet the Canadian 24-hour guidelines in a small Brazilian city. However, further studies with larger and representative samples of sociodemographic stratum are still needed.
