Purpose: Dental problems in young children are widespread and can negatively impact quality of life. We examined the effect of enrollment in North Carolina Early Head Start (EHS)-a federally funded early education program for children under three years of age and their families-on oral health-related quality of life (OHRQoL).
Methods: In this quasi-experimental study, we interviewed 479 EHS and 699 Medicaid matched parent-child dyads at baseline (children's average age 10 months) and 24 months later. Parents reported OHRQoL using the Early Childhood Oral Health Impact Scale (ECOHIS), a 0-52 point scale with higher scores representing more negative impacts. We used a marginalized semicontinuous two-part model to estimate: (1) the effect of EHS on the probability of reporting any follow-up impacts (ECOHIS ≥ 1), and (2) the difference in overall mean ECOHIS follow-up scores. We controlled for baseline ECOHIS, language, and EHS and non-EHS group imbalances using a propensity score.
Results: At follow-up, negative OHRQoL impacts were more often reported by parents of non-EHS than EHS children (45 versus 37%, P < .01). In the adjusted model, EHS parents reported a lower odds of negative OHRQoL impacts (OR 0.70; 95% CI 0.52, 0.94). Mean adjusted ECOHIS scores were not significantly different (EHS: 1.59 ± 3.34 versus non-EHS: 2.11 ± 3.85, P > 0.05).
Conclusions: This study is the first to demonstrate that families of young children enrolled in EHS report improved OHRQoL compared to their non-enrolled peers. These results highlight the potential effectiveness of improving the quality of life of low-resource families through early childhood education.
