Associations between self-reported sleep duration and cardiometabolic risk factors in young African-origin adults from the five-country modeling the epidemiologic transition study (METS)

Association between cardiometabolic health and objectively-measured, free-living sleep parameters in a rural African setting: a pilot study.

“…In contrast with some self-reported PA studies [4], we found PA volume to be signi cantly and independently related to HOMA-IR, but not associated with JIS-MetS risk as in other self-report studies [5]. Interestingly, other lifestyle factors such as concurrent alcohol and tobacco use, and the consumption of SSB were independently associated with poor cardiometabolic health.…”

“…Our ndings are in agreement with the linear relationship between sleep duration and HOMA-IR in black, urban women, although we found far more women had short sleep time compared with self-report measures [4]. A recent study from the METS group found long sleep duration in a black, urban South African sample [5].…”

“…Some have speculated that poor sleep quality might be underpinning the long self-reported sleep durations in South African settings and hence the poorer cardiometabolic health associated with long sleep [4,5]. Our results suggest that fragmented, poor sleep quality, independent of sleep duration might be more important than sleep duration.…”

“…Sleep health is closely linked to metabolic health [1], and while there is extensive literature from industrialised settings [2], there is a paucity of data from African settings, especially free-living, objective measures of sleep [3]. Within the South African context, self-reported long sleep duration is associated with poor cardiometabolic health in mainly urban settings [4,5]. Given the lack of objectively-measured, free-living sleep parameters in any South African setting, the objective of this study was to use wristactigraphy to investigate the association between sleep parameters and cardiometabolic health in a rural African setting during a cross-sectional survey, and thus extend the ndings of self-report sleep duration and cardiometabolic health [4][5][6] Methods Dikgale Health and Demographic Surveillance System site (DHDSS) sample A convenience sample of 167 adults was recruited from the DHDSS site [7].…”
