Mental health and sleep quality across different physical activity intensities: A cross-sectional epidemiological analysis.

Individuals with sleep disturbance who spend lesser time in light physical activity are significantly more likely to present anxiety symptoms.

• OR = 7.33; 95% CI = 2.42–16.94 for the association between sleep disturbance and anxiety symptoms at lower light PA duration
• Models were adjusted for confounding factors including age, sex, and socioeconomic status
• Sample consisted of 229 adults with mean age 42.12 ± 17.02 years
• PA intensities were assessed objectively using accelerometers

Individuals with sleep disturbance who spend lesser time in vigorous physical activity are significantly more likely to present anxiety symptoms.

• OR = 6.39; 95% CI = 2.34–17.46 for the association between sleep disturbance and anxiety symptoms at lower vigorous PA duration
• Binary logistic regression models were used for analysis
• Models were adjusted for age, sex, socioeconomic status, and PA intensities

Individuals with sleep disturbance who spend lesser time in light physical activity are significantly more likely to present depressive symptoms.

• OR = 5.61; 95% CI = 1.32–23.80 for the association between sleep disturbance and depressive symptoms at lower light PA duration
• Sleep quality was assessed using the Pittsburgh Sleep Quality Index
• Depression symptoms were assessed using the Hospital Anxiety and Depression scale

Individuals with sleep disturbance who spend lesser time in vigorous physical activity are significantly more likely to present depressive symptoms.

• OR = 4.57; 95% CI = 1.46–14.30 for the association between sleep disturbance and depressive symptoms at lower vigorous PA duration
• Anxiety symptoms were also assessed using the Hospital Anxiety and Depression scale
• Habitual PA intensities assessed included light, moderate, moderate-vigorous, and vigorous categories

At longer durations of light, moderate, and vigorous physical activity, the associations between sleep quality and mental health symptoms are no longer significant, with one exception.

• The association between sleep quality and anxiety symptoms at moderate intensity PA remained significant at longer durations (OR = 4.93; 95% CI = 1.09–22.23)
• Associations between sleep disturbance and depressive symptoms were no longer significant at longer durations of all PA intensities examined
• This suggests a moderating role of PA duration on the sleep–mental health relationship

The study used a cross-sectional design with 229 adults to examine the relationship between PA intensity, sleep quality, and mental health symptoms.

• Participants had a mean age of 42.12 ± 17.02 years
• Sleep quality was measured with the Pittsburgh Sleep Quality Index
• Anxiety and depression symptoms were measured with the Hospital Anxiety and Depression scale
• Physical activity intensities (light, moderate, moderate-vigorous, and vigorous) were objectively assessed via accelerometers
• Binary logistic regression models were adjusted for age, sex, and socioeconomic status
