“…In determining the effects of sleep timing on appetite and reward behavior, it is difficult to disentangle circadian effects from the effects of sleep curtailment, as night shift work is associated with short sleep duration and reduced sleep quality (72) , and social jetlag is also more common in short-sleepers (20) . However, observational data indicate that social jetlag is independently associated with increased appetite for food (73) and preliminary evidence suggests independent effects of social jetlag on brain regions associated with reward and food craving (74) . In most cases, short sleep, poor sleep quality and irregular sleep timing coincide, and it is likely that they all contribute in multiple ways to poor diet quality and increased risk of weight gain (Fig.…”

Sleep habits are directly related to risk of obesity and this relationship may be partly mediated through food choices and eating behaviour. Short sleep duration, impaired sleep quality and suboptimal sleep timing are all implicated in weight gain and adverse cardiometabolic health, at least partly mediated through their associations with diet quality. Short term sleep restriction leads to increased energy intake, and habitually short sleepers report dietary intakes that indicate a less healthy diet compared to adequate sleepers. Evidence is emerging that sleep extension interventions in short sleepers may reduce intake of sugars and overall energy intake. Poor sleep quality, night shift work patterns and social jetlag are also associated with lower diet quality and consumption of energy-dense foods. Incorporating sleep advice into weight management interventions may be more effective than energy-restricted diets and exercise advice alone. However, there are a lack of intervention studies that aim to lengthen sleep, improve sleep quality, or adjust irregular sleep timing to investigate the impact on dietary intakes and eating behaviour in participants aiming to lose weight or maintain weight loss. Finally, future research should take account of individual characteristics such as age, sex, life stage, and changing working practices when designing combined lifestyle interventions including sleep behaviour change for health and wellbeing.

“…However, increased reward valuation of food has been brought forth as the most likely driver of the rise in energy intakes following short sleep [11]. The association between the hedonic system and short sleep duration has been supported by neuroimaging studies showing an increase in the neuronal responses to food stimuli in regions of the brain related to the reward system and involved in hedonic feeding following sleep deprivation [12][13][14][15][16]. These findings indicate that underpinnings of the sleep-obesity relation are biopsychosocial.…”

Actigraphy-Derived Sleep Is Associated with Eating Behavior Characteristics

Poor sleep is a determinant of obesity; with overconsumption of energy contributing to this relationship. Eating behavior characteristics are predictive of energy intake and weight change and may underlie observed associations of sleep with weight status and obesity risk factors. However; relationships between sleep and dimensions of eating behavior; as well as possible individual differences in these relations; are not well characterized. Therefore; the aim of this study was to evaluate whether sleep behaviors; including duration; timing; quality; and regularity relate to dietary restraint; disinhibition; and tendency towards hunger and to explore whether these associations differ by sex. This cross-sectional study included 179 adults aged 20–73 years (68.7% women; 64.8% with BMI ≥ 25 kg/m2). Sleep was evaluated by accelerometry over 2 week. Eating behavior dimensions were measured with the Three-Factor Eating Questionnaire. Prolonged wake after sleep onset (WASO) (0.029 ± 0.011; p = 0.007), greater sleep fragmentation index (0.074 ± 0.036; p = 0.041), and lower sleep efficiency (−0.133 ± 0.051; p = 0.010) were associated with higher dietary restraint. However; higher restraint attenuated associations of higher WASO and sleep fragmentation with higher BMI (p-interactions < 0.10). In terms of individual differences; sex influenced associations of sleep quality measures with tendency towards hunger (p-interactions < 0.10). Stratified analyses showed that; in men only; higher sleep fragmentation index; longer sleep onset latency; and lower sleep efficiency were associated with greater tendency towards hunger (β = 0.115 ± 0.037; p = 0.003; β = 0.169 ± 0.072; p = 0.023; β = −0.150 ± 0.055; p = 0.009; respectively). Results of this analysis suggest that the association of poor sleep on food intake could be exacerbated in those with eating behavior traits that predispose to overeating; and this sleep-eating behavior relation may be sex-dependent. Strategies to counter overconsumption in the context of poor quality sleep should be evaluated in light of eating behavior traits

“…Há um deslocamento da meia fase do sono nos dias de descanso de mais de uma hora. Estudos recentes utilizaram o limiar de uma hora para caracterizar indivíduos que estão submetidos ao fenômeno de jetlag social (MOTA et al, 2017;NECHIFOR et al, 2020). Em relação a observação da maior estabilidade do período do passo ao longo do teste, existe um segundo processo envolvido.…”
