Background and aim:
The aim of this study was to investigate the association between short sleep duration and cardiovascular disease (CVD) risk factors including hypertension, diabetes among urban rural population. The contribution of social economic status (SES) and lifestyle factors were also examined to this association.
Method:
A total of 12,925 participants (aged >35 years) from a representative samples from Bangladesh. Short sleep duration was defined as <7 h/night. Cardiovascular disease included hypertension and/or diabetes mellitus. The association between short sleep and CVD risk factors, along with the contribution of SES and lifestyle factors, was assessed using prevalence ratios (PRs).
Results:
Urban-rural sleep difference was reported higher in rural population. Average sleep was report in rural 8.1 (±1.4 (±SD) vs 7.5 ± 1.4 (SD). Short sleep was significantly higher in urban area (P<0.001). The risk of cardiovascular disease is higher (Odds Ratio= 1.6; 95% CI, 1.2-2.3) among short sleeper in urban areas. The association is statistically significant (P<0.002).
Conclusion:
The findings indicate that short sleep is associated with cardiovascular disease in urban settings. Further studies are warranted to establish the potential factors that might lead to the observed differences across populations and appropriate intervention to address SDG.
