“…Despite a clear association between short sleep duration and increased obesity risk, 10 relatively few interventions have been undertaken. Slower infant weight gain was reported after provision of parental education regarding soothing sleep strategies, 12, 14 and significant differences in sleep duration and BMI were observed in 2-to 5-yearold children after the use of a multifaceted intervention.…”

“…6 Early-life obesity prevention has typically focused on encouraging healthy eating and increasing physical activity, with surprisingly inconsistent results, 4,5 thus prompting interest in assessing other behaviors (including sleep). 9 Observational studies support a strong inverse association between sleep duration and obesity in childhood, 10 and plausible biological mechanisms (eg, changes to eating/ activity habits or appetite-regulating hormones) exist to explain this relationship. 11 However, whether sleep behavior can change weight trajectories early in life has not been well studied.…”

Targeting Sleep, Food, and Activity in Infants for Obesity Prevention: An RCT

et al. 2017

View full text Add to dashboard Cite

The few existing early-life obesity prevention initiatives have concentrated on nutrition and physical activity, with little examination of sleep. METHODS:This community-based, randomized controlled trial allocated 802 pregnant women (≥16 years, <34 weeks' gestation) to: control, FAB (food, activity, and breastfeeding), sleep, or combination (both interventions) groups. All groups received standard well-child care. FAB participants received additional support (8 contacts) promoting breastfeeding, healthy eating, and physical activity (antenatal-18 months). Sleep participants received 2 sessions (antenatal, 3 weeks) targeting prevention of sleep problems, as well as a sleep treatment program if requested (6-24 months). Combination participants received both interventions (9 contacts). BMI was measured at 24 months by researchers blinded to group allocation, and secondary outcomes (diet, physical activity, sleep) were assessed by using a questionnaire or accelerometry at multiple time points. RESULTS:At 2 years, 686 women remained in the study (86%). No significant intervention effect was observed for BMI at 24 months (P = .086), but there was an overall group effect for the prevalence of obesity (P = .027). Exploratory analyses found a protective effect for obesity among those receiving the "sleep intervention" (sleep and combination compared with FAB and control: odds ratio, 0.54 [95% confidence interval, 0.35-0.82]). No effect was observed for the "FAB intervention" (FAB and combination compared with sleep and control: odds ratio, 1.20 [95% confidence interval, 0.80-1.81]). CONCLUSIONS:A well-developed food and activity intervention did not seem to affect children's weight status. However, further research on more intensive or longer running sleep interventions is warranted.

“…A meta analysis of 11 longitudinal studies involving 24 821 participants revealed that subjects whose sleeping was within the short duration range had twice as much risk of becoming overweight or obese compared to subjects who slept for long periods (OR 2.15; CI 95%: 1.64-2.81). 26 Additionally, there are studies suggesting that the chronic lack of sleep from childhood up to school age in children it is associated to a higher metabolic risk 27 and that sleep duration reversely predicts cardiometabolic risk among obese adolescents. The significant role of sleep in modulating hormonal release could explain the association between fewer sleeping hours and obesity.…”

Introduction. Studies mainly performed in adults have shown an association between the amount of sleep and obesity. Objective. To determine if there is an association between nocturnal sleep deprivation during the week and the weekend, eating habits, physical activity and nutritional status among Chilean schoolchildren. Population, Material and Methods. Crosssectional study. An anthropometric assessment was done among 6-11 year-old students; the Pittsburgh Sleep Quality Index (PSQI) was used among parents to measure their children´s quality of sleep; they were asked about eating habits and physical activity. Results. One thousand eight hundred and ten schoolchildren of both sexes, attending public schools in Santiago, were assessed. Out of these schoolchildren, 49.9% slept fewer hours per night than recommended. An association in the crude model (crude OR 1.82; CI 95%: 1.29-2.56), in model 2 adjusted for cola drinks (OR 1.83; CI 95%: 1.30-2.59) and in model 3 adjusted for dinner, cola drink and caffeine beverage consumption and nocturia (OR 1.85; CI 95%: 1.30-2.62) was observed. It was also noticed that exercising was a protective factor against overweight and obesity; however, periodic limb movement during sleep was a risk factor. Conclusions. This study showed an association between fewer hours of sleep and an increase in the risk of overweight/obesity.

“…2 Inadequate sleep has been associated with poorer cognitive, psychomotor, physical, and socioemotional development, which includes emotion regulation, mood, and behavior in infancy and childhood. 3 -6 Insufficient sleep is generally accepted as an important risk factor for obesity, 7,8 with links between sleep and weight beginning in infancy. 9 -14 Short sleep duration during infancy is also associated with inadequate sleep later in childhood, 15 emphasizing the importance of developing healthy sleep-related behaviors during the first months after birth.…”

Mother-Infant Room-Sharing and Sleep Outcomes in the INSIGHT Study

et al. 2017

The American Academy of Pediatrics recommends infant-parent room-sharing until age 1. We assessed the association between room-sharing and sleep outcomes. METHODS:The Intervention Nurses Start Infants Growing on Healthy Trajectories study is an obesity prevention trial comparing a responsive parenting intervention with a safety control among primiparous mother-infant dyads. Mothers completed the Brief Infant Sleep Questionnaire at 4, 9, 12, and 30 months. Reported sleep duration and overnight behaviors, adjusted for intervention group, were compared among early independent sleepers (own room <4 months), later independent sleepers (own room between 4 and 9 months), and room-sharers at 9 months. RESULTS:At 4 months, reported overnight sleep duration was similar between groups, but compared with room-sharers, early independent sleepers had better sleep consolidation (longest stretch: 46 more minutes, P = .02). At 9 months, early independent sleepers slept 40 more minutes nightly than room-sharers and 26 more minutes than later independent sleepers (P = .008). The longest stretch for early independent sleepers was 100 and 45 minutes more than room-sharers and later independent sleepers, respectively (P = .01). At 30 months, infants sleeping independently by 9 months slept >45 more minutes nightly than those room-sharing at 9 months (P = .004). Room-sharers had 4 times the odds of transitioning to bed-sharing overnight at both 4 and 9 months (P < .01 for both). CONCLUSIONS:Room-sharing at ages 4 and 9 months is associated with less nighttime sleep in both the short and long-term, reduced sleep consolidation, and unsafe sleep practices previously associated with sleep-related death.
