High-level summary of findings by health indicator
| Health Indicator | # of studies | Quality of Evidence | Summary of Findings |
|---|---|---|---|
| Critical | |||
| Adiposity | 31 | Low |
N = 20 studies reported a significant association between shorter sleep duration and adiposity. N = 9 studies reported null findings. N = 2 studies reported a significant association between longer sleep duration and adiposity. |
| Emotional Regulation | 25 | Very Low to High |
N = 13 studies reported a significant association between shorter sleep duration and poorer emotional regulation. N = 10 studies reported null findings. N = 2 studies reported a significant association between longer sleep duration and poorer emotional regulation. |
| Cognitive Development | 16 | Low to High |
N = 6 studies reported a significant association between shorter sleep duration and poorer cognitive function. N = 8 reported null findings. N = 2 study reported a significant association between longer sleep duration and poorer cognitive function. |
| Motor Development | 2 | Low | N = 2 studies reported null findings. |
| Growth | 2 | Very Low | N = 2 studies reported better growth with longer sleep duration. |
| Important | |||
| Sedentary Behavior | 5 | Very Low | N = 5 studies reported shorter sleep duration was associated with more screen time. |
| Physical Activity | 4 | Low to Very Low |
N = 2 studies reported longer sleep duration was associated with more physical activity. N = 2 studies reported null findings. |
| Risks/Injuries | 3 | Low |
N = 2 studies reported a higher risk of injuries with shorter sleep duration. N = 1 study reported null findings. |
| Quality of Life/Well-Being | 1 | Very Low | N = 1 study reported null findings. |
| Cardio-Metabolic Health | 0 | N/A | N/A |
The number of studies is more than N = 69 because some papers had more than one outcome measure and/or study design
