Reducing Disparities in Dental Care for Low-Income Hispanic Children

This study used a social ecological model to examine the influences of sociodemographic factors, mothers; attitudes, financial barriers, and the healthcare delivery system on the use of dental services for 4- to 8-year-old Hispanic children. The results showed that initiating dental care during the preschool years was significantly related to the mothers; beliefs and their social networks ; beliefs in the value of preventive dental care. In addition, extended clinic hours increased the likelihood of returning to the dentist. Provider availability, dental insurance, and family income were related to frequency of planned visits.


Determinants of Dental Referral Practices among WIC Nutritionists in North Carolina

The purpose of the study was to examine the effects of knowledge and confidence on dental referral practices among WIC nutritionists in North Carolina. The study showed that the more confident WIC nutritionists felt about their ability to assess oral health risk, the more likely they were to make dental referrals. Because a child's first point of contact with a health professional is frequently at a WIC clinic, WIC workers might improve children's access to dental care, by providing screenings and referrals.


Underimmunization in Chicago Children who Dropped Out of WIC

This retrospective cohort study determined whether children who remained active at WIC immunization-linked sites after their first birthday were more likely to be immunized by ages 19 months and 25 months than those who had dropped out. The study concluded that children who participated in WIC were more likely to be immunized, compared with children who had dropped out of WIC.


Racial/ethnic disparities in preschool immunizations: United States, 1996 – 2001

The authors analyzed current racial and ethnic differences in immunization coverage rates among US preschool children. During the 6-year study period, the immunization coverage gap between white and black children widened by an average of 1.1% each year, and the gap between white and Hispanic children widened by an average of 0.5% each year. The gap between white and Asian children narrowed by an average of 0.8% each year.


Factors Associated with Underimmunization at 3 Months of Age in Four Medically Underserved Areas

This study examines coverage rates and factors associated with underimmunization at 3 months of age in four medically underserved areas. Vaccination coverage levels at 3 months of age varied across sites: They were 82.4% in northern Manhattan, 70.5% in Detroit, 82.3% in San Diego, and 75.8% in rural Colorado. Among children who were not up to date, the majority (65.7% to 71.5%, per site) had not received vaccines because of missed opportunities.


Effects of WIC Participation on Children’s Use of Oral Health Services

According to the results, children who participated in WIC had an increased probability of having a dental visit, were more likely to use preventive and restorative services, and were less likely to use emergency services.


Maternal Characteristics Associated with Vaccination of Young Children

The authors analyzed maternal characteristics associated with vaccination in US preschool children. Results showed that factors most strongly associated with undervaccination included mothers who were black; had less than a high school education; were divorced, separated, or widowed; had multiple children; were eligible for WIC, but not participating; or had incomes below 50% of the federal poverty level.


Caries Prevalence of Children in an Infant Oral Health Educational Program at a WIC Clinic

The study compared the prevalence of caries between children whose parents had previously participated in an infant oral health education program at a WIC clinic with those whose parents had not participated in such a program. The study results showed that parents ; previous WIC education program participation was highly associated with lower carious lesions. The research indicated that WIC could have a positive impact on caries prevention.
