Insights
Moderately preterm birth and low socioeconomic status (SES) significantly increase children's risk for behavioral and emotional problems. These combined factors, particularly in girls, highlight the need for early intervention strategies.
Area of Science:
- Pediatrics
- Developmental Psychology
- Public Health
Background:
- Moderately preterm (MP) birth (32-36 weeks gestation) is linked to increased behavioral and emotional issues.
- The contribution of low socioeconomic status (SES) to these issues in MP children requires further investigation.
Purpose of the Study:
- To assess the independent and joint effects of MP birth and low SES on behavioral and emotional problems.
- To examine these effects overall and by gender in a population-based sample.
Main Methods:
- Utilized a population-based sample of 915 MP and 543 term-born children.
- Employed multivariable logistic regression to analyze risks associated with gestational age and SES.
- Assessed behavioral and emotional problems using the Child Behavior Checklist at age 4.
Main Results:
- MP children with low SES exhibited higher total problem scores compared to those with high SES (11.3% vs. 5.1%).
- Each standard deviation decrease in SES increased the odds of elevated total problem scores by 42%.
- MP birth independently increased the risk of behavioral problems, with effects more pronounced in girls.
Conclusions:
- Moderately preterm birth and low SES act synergistically to elevate the risk of behavioral and emotional problems.
- Identifying children with this combination of risk factors is crucial for targeted early intervention.
- The findings underscore the importance of addressing both prematurity and socioeconomic factors in child development.
Abstract:
Moderately preterm (MP) birth is associated with higher rates of behavioural and emotional problems. To determine the extent to which low socioeconomic status (SES) contributes to these higher rates, we assessed independent and joint effects of MP birth and low SES, overall and by gender. Dutch preventive child health care centres provided a population-based sample of 915 MP children (32-36 weeks gestation) and 543 term-born children, born in 2002/2003. In multivariable logistic regression analyses, we determined the risk of behavioural and emotional problems per standard deviation (SD) decrease in gestational age and SES, using standardized measures for both. We also assessed three SES categories, being low (1SD or more below mean of standardized SES), intermediate (mean ± 1SD), and high (greater than mean + 1SD). The Child Behavior Checklist for 1.5-5 years was used to assess behavioural (externalizing), emotional (internalizing), and total problems at age 4 years. MP children with low SES had significantly higher total problem scores than those with high SES (11.3 vs. 5.1%, respectively). Each SD decrease in SES was associated with a 42% higher odds of elevated total problem scores (OR 1.42, 95% CI 1.14-1.77). No joint effects were found, meaning that lower gestational age independently added to the risk of behaviour problems (OR 1.24, 95% CI 1.00-1.56). Effects of MP birth and low SES were more pronounced in girls. In conclusion, MP birth and low SES multiply the risk of behavioural and emotional problems. The combination of risk factors identifies children who could benefit greatly from early intervention.
