Recently, the Canadian 24-Hour Movement Guidelines for Adults were released, and included a revised physical activity (PA) recommendation. The recommendation of 150 minutes per week of moderate-to-vigorous intensity PA (MVPA) was revised, from requiring that MVPA be accrued in bouts of 10 minutes or more (bouted) to having no bout requirement (non-bouted). The objective of this study was to assess whether there were differences in sociodemographic, health and fitness characteristics of Canadians who met the bouted and non-bouted PA recommendations.
Using adult (aged 18 to 79 years) accelerometer data from three combined cycles of the nationally representative Canadian Health Measures Survey (N = 7,102), this study compared adherence to the bouted and non-bouted recommendations. Differences in sociodemographic, health and fitness measures were assessed using independent t-tests and chi-squares. Multivariate linear and logistic regressions controlling for age, sex, household education and smoking examined associations with health and fitness measures.
More adults met the PA recommendation using the non-bouted versus bouted (45.3% vs. 18.5%) requirement. Characteristics of those who met the bouted and only the non-bouted recommendations were similar. Exceptions among those who met only the non-bouted recommendation compared with meeting the bouted recommendation included fewer adults aged 65 years and older; lower MVPA, recreation PA and transport PA; and higher sedentary time, light PA and grip strength.
Although the removal of the 10-minute bout requirement increased the proportion of Canadian adults who met the PA recommendation, there were no substantial differences in the sociodemographic and health characteristics of the populations captured by the bouted and non-bouted definitions. Results help to inform the transition in reporting for PA surveillance.
最近，加拿大发布了成年人 24 小时运动指南，其中包括对体力活动（PA）建议的修订。每周 150 分钟的中等至剧烈强度 PA（MVPA）的建议，从要求 MVPA 以 10 分钟或更长时间的段（分段）积累改为没有段要求（非分段）。本研究的目的是评估符合分段和非分段 PA 建议的加拿大人在社会人口统计学、健康和体能特征方面是否存在差异。
使用来自全国代表性加拿大健康测量调查（N = 7102）三个组合周期的成年（18 至 79 岁）加速度计数据，本研究比较了对分段和非分段建议的遵守情况。使用独立 t 检验和卡方检验评估社会人口统计学、健康和体能测量的差异。使用多元线性和逻辑回归，控制年龄、性别、家庭教育和吸烟状况，检查与健康和体能测量的关联。
更多的成年人使用非分段而非分段（45.3% 比 18.5%）要求符合 PA 建议。符合分段和仅符合非分段建议的成年人的特征相似。仅符合非分段建议的成年人与符合分段建议的成年人相比，例外情况包括年龄在 65 岁及以上的成年人较少；MVPA、娱乐 PA 和交通 PA 较低；久坐时间、轻度 PA 和握力较高。
虽然取消 10 分钟段要求增加了符合 PA 建议的加拿大成年人的比例，但在分段和非分段定义所涵盖的人群的社会人口统计学和健康特征方面没有实质性差异。结果有助于为 PA 监测报告的转变提供信息。
