Acculturation and Children's dental service utilization in the United States.

OBJECTIVE: The study examined changes in acculturation level, socio-economic status, and their association with preventive dental service use, receipt of restorative, or surgical care, and unmet dental needs.

METHODS: Data from the Medical Expenditure Panel Survey (MEPS) for children aged 1 to 17 years from 2007 to 2015 were analysed. Firstly, a cross-sectional structural equation model (SEM) that included both a measurement model and a structural model was fitted simultaneously to obtain predicted latent variables for acculturation, socio-economic status (SES), dental service utilization, and unmet dental needs. Secondly, the change in acculturation, SES, dental service utilization, and unmet dental needs were calculated over two consecutive years within the same child. Finally, the structural model in these changes was fitted, and the indirect and direct pathways between acculturation and SES were tested with dental insurance as a mediator.

RESULTS: Data for 33 507 children in both panel years were analysed. An increase in family acculturation resulted in lower utilization of preventive dental service and more unmet dental need, with socio-economic status and dental insurance kept constant between the panel years, and after adjusting for race/ethnicity, gender, and age. In addition, increased acculturation was associated with higher SES, and a higher probability of having obtained dental insurance, both of which resulted in increased preventive dental service utilization and less unmet dental need. The positive direct effect and negative indirect effect of acculturation on unmet dental need cancelled each other out and resulted to almost zero total effect between acculturation and unmet dental need. Similarly, the negative direct effect and positive indirect effect of acculturation on preventive dental service cancelled each other out leading to a small increase in preventive dental service utilization.

CONCLUSION: Children of immigrant families are at risk of inadequate access to dental care as their families becomes more acculturated, without increase in SES and access to dental insurance. This study supports policies that promote immigrant family's adequate access to dental insurance and employment to improve their socio-economic status.
