Sleep duration and health status self-assessment (SF-36) in the elderly: a population-based study (ISA-Camp 2008)

“…A study carried out in Brazil found that sleeping for six or less hours was strongly associated with poor sleep 11 . According to a study by Wilkelman et al 29 , elderly individuals with restless legs syndrome obtained worse scores for the vitality and mental health scales and all scales of the mental component summary.…”

“…An association has been reported between sleep duration under 7 to 8 hours (considered the medium sleep duration pattern of sleep) and an increase in mortality from all causes 6,7 , in addition to a greater prevalence of diseases such as diabetes 8 , hypertension 9 , depression 10 , rheumatic disease, osteoporosis 11 and obesity 12,13 .

Sociodemographic and health correlates of sleep problems and duration in older adults in South Africa

“…To capture possible non-linear associations between sleep duration and its associates, we followed a similar categorisation used by previous studies and classified sleep hours into ≤6, 7 -8, 9, and ≥10 h/day. 20 The category of 7 -8 h/day was used as reference to allow for comparison with earlier studies on older adults. 6,20 This reference category was chosen because some studies reported that those who slept 7 -8 h usually had the lowest mortality risk.…”
