Study Finds Significant Mental Health Challenges Among Preschoolers in Lisbon Area

The study involved 760 children but specifically analyzed 453 whose caregivers completed a Strengths and Difficulties Questionnaire (SDQ), a tool that assesses various emotional and behavioral areas. The researchers defined early mental health difficulties as a Total Difficulties score of 14 or higher. The findings indicate a significant prevalence of mental health issues before formal education starts, an area previously under-researched in Portugal.

Among the children studied, those from lower-income households showed more than double the adjusted odds of falling into the borderline or abnormal range on the SDQ compared to those from higher-income households. Specifically, children from households earning between 750 and 1,500 euros per month had an odds ratio of 2.10, highlighting a correlation between economic hardship and early childhood mental health issues.

Family structure also influenced mental health outcomes. Children living in extended families faced 82% higher adjusted odds of elevated Total Difficulties scores than those in nuclear families. However, the authors note that these findings do not suggest that extended families are inherently detrimental; rather, they may reflect broader socioeconomic challenges.

Physical activity too was linked to mental health, with children who did not participate in sports displaying nearly three times the adjusted odds of elevated difficulties compared to active peers, with an odds ratio of 2.80.

Investigating whether children with immigrant backgrounds had higher rates of mental health difficulties, the study found these children faced greater socioeconomic disadvantages. However, once socioeconomic factors were considered, the difference in mental health difficulties largely diminished, suggesting that underlying economic conditions, rather than immigrant status alone, are significant contributors.

The researchers advocate for integrating mental health screenings within routine pediatric care to identify children at risk during critical developmental periods. They emphasize that early mental health inequalities linked to economic and familial circumstances are evident as early as age four.

While the findings are compelling, the authors acknowledge limitations, such as the inability to establish cause-and-effect relationships, due to the cross-sectional nature of the study. They call for further longitudinal research to better understand these dynamics and the potential benefits of interventions like increased sports participation.

This research represents a significant step in understanding early childhood mental health in Portugal, with implications for policy and community health strategies.
