“…Four studies included male participants exclusively (6,37,39,43) , four studies included only female participants (27,33,38,42) and 16 studies included both male and female participants (7)(8)(9)(10)(11)26,28,31,32,(34)(35)(36)40,41,44,45) . Body mass index (BMI) was reported in all 24 studies and mean BMI was <25 kg m -2 (normal BMI range) in 16 studies (6)(7)(8)11,31,32,34,35,37,(39)(40)(41)(42)(43)(44)(45) and >25 kg m -2 (overweight/ obese BMI range) in seven studies (9,10,26,28,33,36,38) . One study compared dietary outcomes in both healthy weight and overweight participants (27) , one study compared dietary outcomes by sex…”

“…Included studies were 11 randomised cross-over studies (6,9,11,28,33,36,37,(42)(43)(44)(45) , five non-randomised cross-over studies (8,27,35,39,40) , five RCTs (two-arm) (7,10,31,32,41) and three pre-post studies (26,34,38) . Of the 24 studies, 13 were conducted in a laboratory (6)(7)(8)(9)(10)(11)26,28,(31)(32)(33)36,37) , six in a free-living setting (27,34,38,41,42,45) and five in a mixed setting (35,39,40,43,44) . The studies conducted in a mixed setting were all cross-over studies where participants spent part of the experiment in a laboratory (i.e.…”

“…This systematic search identified 23 intervention studies that modified sleep duration and one intervention study that modified sleep timing. Of the 23 studies that modified sleep duration, four studies imposed total sleep restriction (TSR) (32,35,37,40) , 16 studies imposed PSR (duration <5.5 h night -1 ) (6)(7)(8)(9)(10)(11)(26)(27)(28)33,34,38,39,(42)(43)(44) , one study imposed both PSR and TSR (31) and two studies extended time in bed (by 1-1.5 h night -1 ) to increase sleep duration (41,45) . In the 16 studies that partially restricted sleep duration, this was achieved by delaying bedtime and keeping wake-time consistent in seven studies (7,10,26,27,33,39,42) , delaying bedtime and advancing wake-time in six studies (6,8,9,11,28,43) and by delaying bedtime and advancing wake-time on different nights in one study (44) .…”

“…In three of the four studies that assessed TSR in comparison to a control, participants spent 1 night in each condition (32,37,40) . The other study compared one night of TSR with 2 nights in the control condition (35) . In the two sleep extension (SE) studies, the intervention periods were 2-4 weeks (41,45) .…”

Background: Poor dietary intake increases disease risk, and poor sleep influences diet. This systematic review and meta-analysis of intervention studies aimed to evaluate the effect of sleep health on dietary intake in adults. Methods: Five online databases were used to identify studies published between 1970 and 2019. Included studies were interventions that modified sleep and reported dietary outcomes. Results: Fifty four full texts were assessed and 24 publications were included. Following risk of bias appraisal, data were narratively summarised and a subgroup of studies (n = 15) was meta-analysed to determine the effect of sleep on dietary intake. One intervention modified sleep timing and 23 modified duration. Sleep duration was partially restricted (≤5.5 h night-1) (n = 16), totally restricted (n = 4), partially and totally restricted (n = 1), and extended (n = 2). Dietary outcomes were energy intake (n = 24), carbohydrate, fat, protein intake (n = 20), single nutrient intake (n = 5), diet quality (n = 1) and food types (n = 1). Meta-analysis indicated partial sleep restriction results in higher energy intake in intervention compared with control [standardised mean difference (SMD) = 0.37; 95% confidence interval (CI) = 0.21-0.52; P < 0.001], with a mean difference of 204 kcal (95% CI = 112-295; P < 0.001) in daily energy intake, and a higher percentage of energy from fat, protein, carbohydrate (fat: SMD = 0.33; 95% CI = 0.16-0.51; P < 0.001; protein: SMD = 0.30, 95% CI = 0.12-0.47, P = 0.001; carbohydrate: SMD = 0.22, 95% CI = 0.04-0.39, P = 0.014). Conclusions: Partial sleep restriction with duration of ≤5.5 h day-1 increases daily energy intake, as well as fat, protein and carbohydrate intake. Further research is needed to determine the relationship between other dimensions of sleep health and dietary intake.
