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.

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.

Experiences of Indigenous peoples in Canada with primary health care services: a qualitative systematic review protocol.

OBJECTIVE: The objectives of this review are to aggregate and synthesize experiences of Indigenous peoples in Canada when receiving primary health care services; differentiate experiences from services provided in urban versus rural or remote settings; and identify recommendations to enhance quality of primary health care provision. INTRODUCTION: Primary health care plays a crucial role in overall population health and health equity. In Canada, Indigenous peoples continue to face disproportionate health disparities. Survey and qualitative studies on the experiences of Indigenous populations with primary health care services reveal alarming findings of inadequate health care access, racial discrimination, negligence, and cultural insensitivities. However, these studies do not entirely assess the primary care and essential public health functions component. This protocol will be the first qualitative systematic review to thoroughly synthesize Indigenous peoples' overall primary health care experiences across all Canada, in both rural and urban settings. INCLUSION CRITERIA: The population of interest is self-identified Indigenous peoples, who have first- and/or second-hand experience receiving primary health care services in Canada, regardless of their age, gender, or medical condition. Our focus is on patients' experiences in contexts where primary health care services are delivered in Canada. Only qualitative studies in English or French will be considered. METHODS: MEDLINE, CINAHL, PubMed, PsycINFO, Embase, and Web of Science will be used as information sources in addition to Google Scholar, Bielefeld Academic Search Engine, ProQuest Dissertations and Theses, and other relevant organization websites. Two independent reviewers will perform the screening, critical appraisal, and data extraction of selected articles. Results will then be synthesized using the meta-aggregation approach.
