Insights

Bed-sharing, where infants sleep with parents, was common in Southern Brazil. Single mothers and those living with their own mothers were more likely to bed-share at 3 months.

Area of Science:

  • Pediatrics
  • Public Health
  • Sociology

Background:

  • Bed-sharing is a common infant sleep practice with potential safety implications.
  • Understanding the prevalence and associated factors of bed-sharing is crucial for public health interventions.
  • Previous research highlights socioeconomic and cultural factors influencing infant sleep environments.

Purpose of the Study:

  • To determine the prevalence of bed-sharing among mother-infant pairs in an urban population in Southern Brazil.
  • To identify factors associated with bed-sharing practices at 3 and 6 months postpartum.
  • To inform targeted interventions for safe infant sleep environments.

Main Methods:

  • Cross-sectional nested cohort study involving 233 mother-infant pairs.
  • Data collected through home visits at 3 and 6 months postpartum.
  • Poisson regression analysis used to identify factors associated with bed-sharing.

Main Results:

  • At 3 months, 31.2% of infants bed-shared with their mothers; this decreased to 28.5% at 6 months.
  • Bed-sharing prevalence at 3 months was significantly higher for single mothers (Prevalence Ratio [PR]: 1.56) and mothers living with the infant's maternal grandmother (PR: 1.70).
  • These associations remained significant after adjusting for other variables.

Conclusions:

  • Bed-sharing is a prevalent infant sleep arrangement in the studied urban population.
  • Maternal marital status and extended family living arrangements are key factors associated with bed-sharing.
  • Public health strategies should consider these social determinants to promote safe infant sleep practices.

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Relationship with Parents: Attachment01:28

Relationship with Parents: Attachment

Parent-child interactions lay the foundation for how we understand relationships throughout life. These interactions are not uniform across families; instead, they are shaped by a range of environmental, emotional, and behavioral factors unique to each caregiver-child dynamic. Social psychologists study these early relationships to understand how patterns formed in infancy influence social functioning and interpersonal behavior in adulthood.Attachment Theory and Early Relational ModelsJohn...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Attachment01:20

Attachment

Attachment is vital for infant development, as warm social interactions support growth and well-being. In a classic 1958 study by Harry Harlow, the significance of warmth and comfort in forming attachments was examined. Harlow separated newborn monkeys from their mothers and provided two artificial "mothers": one made of cold wire and the other covered in soft cloth. Despite the wire mother offering food, the infant monkeys preferred the comfort of the cloth mother, demonstrating that physical...
Parental Care00:55

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.
