Résumé

Background
Data on meeting the Canadian 24-Hour Movement Guidelines for adults (24-H Guidelines) and associations with health indicators by body mass index (BMI) class are needed to support public health surveillance. The aim of this study was to describe the proportion of Canadian adults meeting individual and various combinations of the 24-H Guidelines by BMI class and their association with health indicators.
Data and methods
Data from the cross-sectional Canadian Health Measures Survey cycles 1 to 4 (2007 to 2015, n = 10,515 adults aged 18 to 79 years) were used. Daily time spent in moderate-to-vigorous physical activity (MVPA) and sedentary behaviour were assessed using accelerometry. Sleep duration, recreational screen time, chronic conditions, sociodemographic characteristics, and general and mental health were self-reported. The BMI, waist circumference, blood pressure and aerobic fitness were directly measured. Respondents were classified as meeting the 24-H Guidelines when
• the MVPA was 150 minutes per week or more
• sedentary time was nine hours or less per day
• recreational screen time was three hours or less per day
• sleep duration was seven to nine hours per day for individuals aged 18 to 64 years or seven to eight hours per day for individuals aged 65 years and older.
Results
Significantly fewer adults with overweight (6.1%) or class I (4.3%) and class II or III (3.9%) obesity met all three 24-H Guidelines compared with those with normal weight (9.5%). Meeting all three or two recommendations of the 24-H Guidelines was generally associated with a lower waist circumference, higher aerobic physical fitness and self-perceived general health regardless of BMI class.
Interpretation
Canadian adults living with overweight and obesity are less likely to meet the 24-H Guidelines. Most of the benefits associated with meeting the 24-H Guidelines are observed regardless of BMI status.
