Heterogeneity in health and lifestyle among preschool children with migrant background in Sweden

Abstract

Abstract Background Parental country of birth and socioeconomic status affect children’s health, lifestyle, and access to care. But inequality patterns may vary depending on the outcome and indicator being studied. While prior studies have focused on single health outcomes, this study assessed the relationship between parental migrant status and a range of health and lifestyle indicators among 3-year-old children. Methods Using an outcome-wide approach, we analyzed data from cross-sectional population-based surveys of 3-year-old (2014-2018) in Northern Sweden, which included 9,099 children aged 33-42 months. The surveys were administered to parents. Logistic and linear regressions were performed to examine the association between parents’ place of birth and outcome indicators. Additionally, we controlled for parents’ income and education using multiple regression models. Results Children with at least one migrant parent were perceived by their parents to have poorer health (OR:1.5, CI:1.01-2.36) and more socio-emotional problems (OR: 2.8, CI: 2.20-3.59) compared to those with two Swedish parents. While there were no significant differences in estimated BMI, lifestyle indicators showed that these children consumed more sweets (OR:4.5, CI: 3.02-6.58), less milk (OR: 1.3, CI: 1.09-1.55), fewer vegetables (OR:1.6; CI: 1.22-2.05) and brushed their teeth less frequently (OR: 2.8, CI: 2.17-3.53). However, they spent more time playing outdoors on weekdays (OR:1.6, CI:1.22-2.00) and weekends (OR: 1.5, CI: 1.18-1.94), but screen time remained consistent between weekdays and weekends. Conclusions Parental migrant status has varying impacts on children’s health and lifestyle, with some indicators showing worse outcomes for children with migrant parents compared to those with Swedish parents, while others do not. An outcome-wide approach is crucial for targeted actions to strengthen protective factors and mitigate risk factors, and ultimately reduce inequalities in early childhood. Key messages • The link between parental migrant status and children’s well-being is complex. Not all indicators show worse outcomes, inequality patterns vary based on the specific outcome and indicator measured. • An outcome-wide approach is crucial to identify action areas for targeted interventions to reinforce protective factors and mitigate risk factors, and ultimately reduce inequalities during childhood.
