To sleep or to breastfeed: Associations between feeding method and sleep in infants and children.

AIM: This study aimed to understand the association between feeding method, specifically breastfeeding versus non-breastfeeding, at 6 and 12 months and infant sleep over the first 3 years of life. METHODS: A sample of 444 mother-infant dyads from the Maternal Adversity, Vulnerability and Neurodevelopment cohort were analysed. Based on retrospective maternal reports between 3-24 months, infants' breastfeeding status was determined at 6 and 12 months. Nocturnal sleep duration, longest period of consecutive sleep, and total sleep over 24 h were measured by maternal reports at 6, 12, 24 and 36 months. RESULTS: Generalized Estimating Equations revealed no significant association between feeding status, both at 6 and 12 months, and nocturnal sleep duration or total sleep over 24 h between 6-36 months (p > 0.05). However, breastfeeding at both 6 and 12 months was associated with shorter periods of consecutive sleep, at 6 and 12 months (p < 0.05) but not at 24 and 36 months (p > 0.05). CONCLUSION: Our findings suggest that breastfeeding seems to be associated with more infant sleep fragmentation but not with total sleep duration in early infancy. However, this sleep fragmentation does not persist into later infancy and early toddlerhood.

The investigation of sleep patterns in relation to interpersonal violence victimization and mental health in adolescent girls.

Empirical studies reveal that interpersonal violence victimization is a highly prevalent phenomena in youth and is associated with a host of difficulties, including mental, physical, and behavioral issues. Sleep, a developmentally fundamental process, is implicated in these unfavorable effects. Despite this, little is known about the interplay between interpersonal violence victimization, sleep, and mental health in adolescent girls, who are at greater risk of victimization, sleep problems, and mental health difficulties than boys. OBJECTIVE: The aim of the current study was to identify distinct patterns of sleep problems to understand how they are associated with interpersonal violence victimization and key mental health outcomes, namely dissociation and emotional dysregulation. METHOD: Latent class analyses were conducted on a sample of 706 adolescent girls aged 14-18 (88% of Canadian descent), who completed an online survey. RESULTS: Three classes of sleep were identified: poor-, moderate-, and high-quality sleep. Controlling for posttraumatic stress disorder, classes were found to differ regarding childhood sexual abuse, community violence, and emotional abuse. In addition, exposure to community violence was associated with dissociation only among girls in the poor-quality sleep class, indicating a moderation effect of sleep. CONCLUSION: The findings of this study, while awaiting replication with a more diverse sample, highlight the continued need to understand the interplay between interpersonal violence and sleep quality, which can help to inform trauma-focused clinical interventions.

The association between child sexual abuse and self-reported sleep in adolescent girls.

STUDY OBJECTIVES: Child sexual abuse is associated with negative consequences on both physical and mental health. It has been found to influence child and adolescent sleep, which is an important developmental factor, which also influences mental and physical health. However, the literature examining this topic is plagued by methodological limitations, such as small sample sizes and unvalidated measures. METHODS: Using the Pittsburgh Sleep Quality Index (PSQI), the present study examined 7 self-reported sleep dimensions, including sleep latency, efficiency, duration, disturbances, subjective sleep quality, daytime dysfunction, and use of sleep medication, in a sample of 707 adolescent girls aged 14-18 years old. RESULTS: Statistical analyses revealed that child sexual abuse had a significant moderate association with the total PSQI score. Sexually abused adolescent girls, compared with their nonabused counterparts, reported more sleep difficulties. Significant differences also emerged on all sleep dimensions, with abused girls reporting increased difficulties. However, the magnitude of these associations differed from one dimension to another. CONCLUSIONS: Our findings support the continued study of sleep in adolescent girls who experienced sexual abuse. They also support the use of a fine-grained perspective when assessing various dimensions of sleep health in girls with a history of child sexual abuse for improved tertiary prevention and intervention.

Associations between parental relationship dissolution and child sleep: A systematic review.

Parental relationship dissolution is considered one of the most common adverse childhood experiences. Although sleep is crucial for healthy development of children and very sensitive to environmental changes, it is poorly studied in the context of parental relationship dissolution. The aim of the current study was to systematically review and critically assess the existing literature on the associations between parental relationship dissolution and child sleep (0-18 years old; registered on PROSPERO (CRD42021272720)). PsycInfo, MEDLINE, Scopus, ProQuest Dissertations and Theses Global, Social Work abstracts, and Web of Science Core Collection were searched. Published empirical quantitative studies were included if they reported statistics regarding the association between parental relationship dissolution and any child sleep variable. Out of the 358 articles screened, 14 articles met inclusion criteria and reported on several sleep dimensions: sleep quality, dreams and nightmares, and sleep disorders (enuresis, night terrors, and bruxism). Out of the 14 articles, six were longitudinal studies and eight were cross-sectional studies. While most studies found that parental relationship dissolution was associated with some indices of poorer child sleep, studies were generally of low to moderate quality. Health professionals should assess child sleep in the context of a parental relationship dissolution.
