目前对发展中国家人口体力活动水平和久坐行为的了解有限，主要基于自我报告。我们使用客观和自我报告的方法描述了发展中国家人群的PA水平。使用经验证的问卷（RPAQ）和单独校准的心率和运动感知监测仪，在巴巴多斯人口（25-54岁）的横断面代表性样本中评估PA。RPAQ收集有关4个领域的回忆活动的信息：家庭，工作，交通和休闲。根据世界卫生组织（WHO）指南定义身体活动不足;久坐生活方式定义为每天久坐8小时或更长时间; PA高估定义为当通过客观测量归类为“不活动”时，认为活动足够。根据客观估计，90.5%（95%CI：83.3，94.7）的女性和58.9%（48.4，68.7）的男性没有积累足够的活动量来达到WHO的最低建议。总的来说，50.7%（43.3，58.1%）的人每天久坐8h以上，60.1%（52.8，66.9%）的人高估了自己的活动水平.两种性别自我报告的不活动患病率被低估了28个百分点（95%CI：18，38），但报告的准确性因年龄组、教育水平、职业等级和超重/肥胖状态而异。低PA是更大的社会特权群体：更高的教育水平和更高的职业等级都与客观测量PA和更多的久坐时间。特定领域的自我报告的身体活动能量消耗（PAEE）的教育程度的变化进行了观察：较高的教育水平与更多的休闲活动和职业活动少。根据自我报告，职业性PA是女性和男性PAEE的主要驱动因素，占57%（95% CI：52，61）。男女最受欢迎的休闲活动是散步和园艺。使用客观和自我报告的方法来评估PA和久坐行为提供了重要的补充信息，以指导公共卫生方案。我们的研究结果强调，迫切需要增加PA和减少久坐时间在这个发展中国家的人口。妇女和社会经济地位较高的人特别容易受到体育活动水平低的影响。本文的在线版本（doi：10.1186/s12889-016-3689-2）包含补充材料，可供授权用户使用。
Current understanding of population physical activity (PA) levels and sedentary behaviour in developing countries is limited, and based primarily on self-report. We described PA levels using objective and self-report methods in a developing country population. PA was assessed in a cross-sectional, representative sample of the population of Barbados (25–54 years), using a validated questionnaire (RPAQ) and individually calibrated combined heart rate and movement sensing monitors. The RPAQ collects information on recalled activity in 4 domains: home, work, transport, and leisure. Physical inactivity was defined according to World Health Organization (WHO) guidelines; sedentary lifestyle was defined as being sedentary for 8 h or more daily; PA overestimation was defined as perceiving activity to be sufficient, when classified as ‘inactive’ by objective measurement. According to objective estimates, 90.5 % (95 % CI: 83.3,94.7) of women and 58.9 % (48.4,68.7) of men did not accumulate sufficient activity to meet WHO minimum recommendations. Overall, 50.7 % (43.3,58.1) of the population was sedentary for 8 h or more each day, and 60.1 % (52.8,66.9) overestimated their activity levels. The prevalence of inactivity was underestimated by self-report in both genders by 28 percentage points (95 % CI: 18,38), but the accuracy of reporting differed by age group, education level, occupational grade, and overweight/obesity status. Low PA was greater in more socially privileged groups: higher educational level and higher occupational grade were both associated with less objectively measured PA and more sedentary time. Variation in domain-specific self-reported physical activity energy expenditure (PAEE) by educational attainment was observed: higher education level was associated with more leisure activity and less occupational activity. Occupational PA was the main driver of PAEE for women and men according to self-report, contributing 57 % (95 % CI: 52,61). The most popular leisure activities for both genders were walking and gardening. The use of both objective and self-report methods to assess PA and sedentary behaviour provides important complementary information to guide public health programmes. Our results emphasize the urgent need to increase PA and reduce sedentary time in this developing country population. Women and those with higher social economic position are particularly at risk from low levels of physical activity.
