Joint effect of sleep duration and sleep quality on self-rated health among Canadian adults: estimating relative excess risk due to interaction from a nationwide survey.

ABSTRACT:

Background

Self-rated health (SRH) is a globally recognized measure of health status. Previous studies have established that inadequate sleep duration and trouble falling asleep combinedly has a greater negative impact on health than either factor alone. This study aims to investigate the excess relative risk due to the interaction between short sleep duration and trouble sleeping on SRH.

Method

We used the 2017-18 Canadian Community Health Survey (CCHS) publicly used microdata file. SRH was measured on a 5-point Likert scale from poor to excellent and dichotomized into "Good or Better" and "Fair or Poor." Sleep duration was categorized into "Less than 7 h" and "More than 7 h," while trouble sleeping was categorized as "Yes" or "No." A joint variable derived from these creat
