Dimensions of sleep quality are related to objectively measured eating behaviors among children at high familial risk for obesity
Authors' conclusion
Adverse associations of poor sleep with energy intake may be amplified among children already predisposed to obesity. Furthermore, that fragmented sleep relates to preferential intake of carbohydrates over fat during EAH may suggest alterations in taste preferences with poor sleep.
Study context
- Population
- Children with healthy weight (BMI-for-age < 90%); mean (SD) age 7.4 (0.6) years; BMI z score −0.10 (0.7)
- Participants
- 77 children
- Exposure
- Children at high vs low familial obesity risk
- High riskn = 32
- Low riskn = 45reference
- Outcome
- Associations of actigraphy-measured sleep quality with homeostatic (ad libitum meal) and hedonic (EAH) eating
Methodological detailslaboratory test meals, wrist actigraphy
- Laboratory test meals
- Wrist actigraphy
Main finding
As reported in the abstract
Sleep fragmentation and homeostatic meal energy intake
| Group | β | p |
|---|---|---|
| High risk | 48.6 | p = 0.001 |
High risk
β48.6
pp = 0.001
- Greater sleep fragmentation associated with higher meal energy intake only in high-risk children; p value for interaction
- 0.001
Observational data: associations, not effects.
Further findings
- Carbohydrate intake during eating in the absence of hunger (EAH) (r)
- 0.33, p = 0.003
- Fat intake during EAH (r)
- −0.33, p = 0.003
- Sleep fragmentation not associated with total EAH
