RESUMEN

INTRODUCTION: Children grow up spending most of their time within the family social environment, where they can experience stressful situations such as marital conflict, a non-cohesive environment, parental alcohol use disorder, parental depression, and other parental mental health issues. All these factors are associated with children's developmental delays. OBJECTIVE: We aimed to conduct a scoping review on family stress and family resilience associated with child development delays to examine familial conditions associated with child development. METHODS: We conducted a scoping review of observational studies published between January 2000 to July 2023, indexed in MEDLINE and LILACS databases. We included observational studies that evaluated the history of exposure to violence, and behavioral or emotional symptoms, or mental health problems among children aged 4-12. Data were independently extracted using a structured form. RESULTS: Database searches identified 12,990 different records. A total of 43 articles were included in the review. Three main findings emerged: (1) parental mental health problems, especially depressive symptoms in mothers, were associated with child developmental delays and mental health problems; (2) better parenting practices and cohesive home environment were positively associated with child development, and (3) Vulnerable social environments (e.g., poverty and housing insecurity) may be linked to child mental health problems. CONCLUSIONS: Studies reviewed show that promoting better family dynamics and increasing family cohesion, as well as parenting abilities, are beneficial to a child's socio-emotional development and prevention of child mental health problems. Moreover, increasing family and children's resilience improves the quality of life within family units.

RESUMEN

OBJECTIVE: Mental illness is an important public health concern, often starting early in life and particularly impacting children from low-and middle-income countries. Our aims were to 1) determine, in a representative sample of public preschool 4- to 5-year old children in Brazil, the prevalence of internalizing and externalizing disorders and socioemotional development delays; and 2) to identify modifiable risk factors associated with mental, behavioral, or developmental disorders (MBDD), such as microsystem (i.e., parent-child relationship), mesosystem (social support), and macrosystem contextual factors (neighborhood disadvantage). METHODS: A random sample of public preschool children was recruited in the city of Embu das Artes (São Paulo metropolitan area) (n=1,292 from 30 public preschools). Six-month prevalence of MBDD was measured using the Child Behavior Checklist (CBCL) and the Ages and Stages Questionnaires: Social-Emotional (ASQ:SE). RESULTS: Six-month prevalence estimates were 25.4% for internalizing disorders, 12.1% for externalizing disorders, and 30.3% for socioemotional development delays. MBDD prevalence estimates were higher in families with stressful relationships and parental depression or anxiety, and in families with lower social capital. CONCLUSION: At least 25% of preschool children living in an urban area in Brazil presented a mental health disorder. These mental disorder were associated with modifiable factors such as stressful family relationships and lower social capital. Prevention and intervention measures such as family therapy are needed to decrease such high prevalence.

RESUMEN

Excessive screen media use exposure is a robust childhood predictor of sedentary behavior. The association between excessive exposure to sedentary behaviors (e.g., screen media use) and motor skills and how this association differs across sociodemographic strata is an important knowledge gap that needs to be addressed. The study aims to investigate the association of motor skills and screen media use in preschool children, taking into account sociodemographic variables, physical activity, and sleep profile. A cross-sectional survey of 926 children from 27 preschools was performed. The main outcome was defined as motor skills assessed using the general motor quotient (GMQ). Independent variables included sociodemographic variables, screen media use, screen habits, physical activity, and sleep duration. Logistic regression models were used to estimate the associations between the children's motor skills and each exposure factor. More than 55 percent of the children ate while watching television and 28 percent spent a long time watching television, playing video games, or using a computer, tablet, or cell phone. Excessive screen media use increased the risk of a low GMQ by 72 percent and inactivity in children increased the odds by 90 percent; sleep duration at night decreased the odds of a low GMQ by 51 percent and daytime sleep decreased the odds by 33 percent. Excessive screen media use has been associated with poor motor skills and increased physical inactivity in children, especially among those with prolonged exposure. Our findings can alert parents to the consequences of excessive screen media use and can motivate policymakers to encourage sports and other health-promotion strategies.
