To analyze the association of MSD with physical activity, sedentary behavior and sleep in the Chilean population.
A secondary analysis of the 2017 Chilean National Health Survey was conducted with a sample of 5472 participants. MSD was assessed using the COPCORD questionnaire, classifying participants into groups with and without MSD. Physical activity and sedentary behavior were measured using the Global Physical Activity Questionnaire, and sleep was reported as average weekly hours. Univariable and multivariable logistic regression models were used to determine the associations, adjusted for control variables.
Out of the 5472 eligible participants, 37% (n=2031) reported MSD. The MSD group had a median age of 55 (IQR 40-67) and 70% were women. Moderate to vigorous physical activity, sedentary behavior and sleep in the MSD group was 43 (IQR 0-229) min/day, 120 (IQR 60-240) min/day and 420 (IQR 360-480) min/day respectively. Individuals with MSD had an average of 16 minutes/day (95% CI 5;27) more physical activity, 16 minutes/day (95% CI 6;25) more sedentary behavior, and 17 minutes/day (95% CI -22; -12) less sleep compared to those without MSD. The presence of MSD was associated with sedentary behavior over 4 hours (OR=1.2; 95% CI 1.1-1.3) and sleeping 7-9 hours (OR=0.7; 95% CI 0.6-0.8). However no significant association was found between MSD and meeting the physical activity WHO criteria (OR=1.1; 95% CI 0.98-1.3).
The presence of MSD is associated with prolonged sedentary behavior and a lower likelihood of meeting sleep recommendations, but not physical activity recommendations according to the WHO criteria.
Understanding the impact of MSD on the 24-h behavior is needed to develop effective public health strategies and to allow international comparison. Given the high prevalence of MSD, it is advisable to consider these lifestyle factors when assessing, treating, or designing intervention strategies for this population. Assessing in the clinic how MSD is affecting these behaviors might complement existing treatment options, favoring a person-centered care.
