The effect of circadian preference and sleep disturbances on depression in children 6 to 12 years of age

This study was conducted to determine sleep disturbances and circadian preferences and their possible associations with depression in healthy children 6 to 12 years of age. A total of 111 healthy children (mean age 7.5 years; 62.2% male) were included. Sleep disturbances and depression were determined by the Sleep Disturbance Scale for Children (SDSC) and the Children's Depression Inventory (CDI), respectively. Circadian preference was evaluated by the Morningness - Eveningness Stability Scale improved (MESSi). SDSC was correlated with CDI (r = 0.396, p < 0.001). Morning affect was inversely correlated with CDI (r = -0.405, p < 0.001), SDSC (r = -0.348, p < 0.001), and three subdimensions of SDSC, i.e. disorders of initiating and maintaining sleep (DIMS, r = -0.317, p = 0.001), disorders of arousal (DA, r = -0.375, p < 0.001) and disorders of excessive somnolence (DOES, r = -0.303, p = 0.001). Distinctness was inversely correlated with CDI (r = -0.402, p < 0.001) and SDSC (r = -0.274, p < 0.001). Increased use of electronic devices was associated with higher CDI (p = 0.003), while decreased duration of physical activity with higher SDSC (p = 0.017). Our findings support the recommendations addressing sleep and circadian preferences as lifestyle modifications in reducing depression in children.PMID:37781873 | DOI:10.1080/07420528.2023.2262577
