Sleep Duration and Physical Activity Profiles Associated With Self-Reported Stroke in the United States: Application of Bayesian Belief Network Modeling Techniques

Q: What is the clinical evidence from this study?

Study design: Cross-Sectional. Population: Self-reported stroke (n=288888). Intervention: Physical activity and sleep duration profiles vs. Unfavorable physical activity and sleep profiles. Primary outcome: Self-reported stroke prevalence.

Key result

Engaging in 31 to 60 minutes of vigorous physical activity six times per week combined with 7 to 8 hours of sleep was associated with the lowest prevalence of self-reported stroke.

Why the study?

Are specific profiles of physical activity and sleep duration associated with the prevalence of self-reported stroke in US adults?

Study Design

Type

Cross-Sectional (n=288,888)

Structured PICO

Are specific profiles of physical activity and sleep duration associated with the prevalence of self-reported stroke in US adults?

Population

288,888 non-institutionalized adults from the United States, with a mean age of 47.8 years and 55.7% female, assessed for the association between sleep duration, physical activity, and self-reported stroke.

Exposure

Profiles of physical activity (duration, intensity, and frequency) and sleep duration (short < 7hrs, average 7-8 hrs, long ≥ 9hrs)

Comparator

Different profiles of physical activity and sleep duration

Outcome

Self-reported history of strokepatient reported

Specific combinations of physical activity and optimal sleep duration (7-8 hours) are associated with a lower prevalence of self-reported stroke.

Limitations

NHIS dataset lacks information on specific stroke type and date of stroke
Lack of other clinical stroke risk factors such as atrial fibrillation and atherosclerosis
Unable to investigate the differential association of specific types of physical activities
Cross-sectional design limits causal inference
Bayesian Belief Network modeling relies heavily on the given data

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Certain PA-sleep profiles were associated with lower stroke prevalence; leaves open whether targeted interventions reduce incidence in prospective studies.

Seixas et al. (2018) conducted a cross-sectional in Self-reported stroke (n=288,888). Physical activity and sleep duration profiles vs. Unfavorable physical activity and sleep profiles was evaluated on Self-reported stroke prevalence. Engaging in 31 to 60 minutes of vigorous physical activity six times per week combined with 7 to 8 hours of sleep was associated with the lowest prevalence of self-reported stroke.
