Association of sleep disorders with non-lab-based CVD risk score among Indian population aged above 45 years: insight from Longitudinal Aging Study in India

Background Both sleep disorders and cardiovascular events have been found to increase with age. The current study aimed to find an association between the two.

Methods The current analysis used data from Longitudinal Aging Study in India (LASI) (1st) conducted from April 2017 to December 2018 with sleep disorder as the output variable. Non-lab-based CVD risk score, defined by the WHO (2019) was explanatory variable. Possible confounders were also included in the secondary analysis.

Results Sleep disorder was seen among 11.69%, higher in females, elderly >60 years, rural population, unemployed and those with limited physical activity and self-reported poor health. Increased CVD risk score was associated with higher odds of having sleep disorder [5-9: 1.19 (1.12-1.28), 10-19: 1.31 (1.22-1.40), 20-29: 1.24 (1.09-1.41)]. On stratified analysis, similar results were seen in males but showed higher odds in the highest risk score category in females.

Conclusions Recognition and management of sleep disorders, especially those with cardiovascular comorbidities and risk factors is important.
