A Mixed-Methods Study on Topical Fluoride Beliefs and Refusal Behaviors for Caregivers of Children with Special Health Care Needs.

OBJECTIVE: To understand topical fluoride-related beliefs and refusal behaviors for caregivers of children with special health care needs (CSHCN). METHODS: This was an explanatory sequential mixed methods study. For the quantitative analyses, we surveyed 520 caregivers to (a) compare fluoride-related beliefs between caregivers of CSHCN and caregivers of healthy children and (b) evaluate the association between special health care need (SHCN) status and topical fluoride refusal. We used logistic regression models to generate unadjusted odds ratios, confounder-adjusted odds ratios (AOR), and 95% confidence intervals (CI). For the qualitative analyses, we interviewed 56 caregivers who refused or were hesitant about topical fluoride. Data were coded deductively and compared by SHCN status to an existing conceptual model of topical fluoride refusal. RESULTS: In the quantitative analysis, 41.3% of caregivers refused or thought about refusing topical fluoride. There were no significant differences in fluoride beliefs by SHCN status (p-values > 0.05) nor was there a significant association between SHCN status and topical fluoride refusal (AOR: 0.65, 95% CI 0.37-1.14; p = 0.13). In the qualitative analysis, the relative importance of each domain of the conceptual model was similar between the caregiver groups. Two differences were that all caregivers of CSHCN thought fluoride was unnecessary and wanted to keep chemicals out of their child's body. CONCLUSIONS FOR PRACTICE: While caregivers of CSHCN were not more likely to refuse topical fluoride than caregivers of healthy children, there may be important differences in the underlying reasons for refusing topical fluoride.

Food insecurity and its relationship to mental health and oral health in older adults.

BACKGROUND AND OBJECTIVES: Poor oral health disproportionately affects low-income older adults, for whom food insecurity and poor mental health may affect dental health. We explored the associations between food insecurity, mental health, and dental health. Furthermore, we examined whether mental health impacted the associations between food insecurity and dental health. MATERIALS AND METHODS: We conducted a cross-sectional study with a convenience sample of 226 older adults (aged 50+), employing survey and dental screening data. Participants were recruited from seven community-based organisations in Washington State, USA. We calculated descriptive statistics and conducted Chi-square tests, t tests, and logistic regression analyses to assess the associations between aspects of dental health (untreated decay, gum disease, and unmet dental needs), mental health (depression and cognitive function), and food insecurity. RESULTS: In our sample, food insecurity was observed in 28.4%, 40.6% had untreated decay, 31.6% gum disease, and 42.5% unmet dental needs. Food insecurity was associated with a higher occurrence of untreated decay and unmet dental needs. Participants experiencing food insecurity had higher odds of gum disease (aOR = 2.3; 95% CI: 1.1, 5.2) and unmet dental needs (aOR = 3.2; 95% CI:1.4, 7.6). Greater gum disease due to food insecurity was observed among individuals with lower levels of cognitive impairment. CONCLUSION: Food insecurity is associated with poorer oral health among older adults and cognitive function may modify this relationship. These findings underscore the importance of addressing both food insecurity and cognitive impairment as integral components of efforts to improve the oral health of older adults.

The association of food insecurity with tooth decay and periodontitis among middle-aged and older adults in the United States and Korea.

INTRODUCTION: Food insecurity is an important social determinant of health, but there is limited understanding of its relationship with adult oral health. This study examined the associations between food insecurity and dental diseases (caries and periodontitis) among middle-aged and older adults in the United States and South Korea. METHODS: This study focused on middle-aged (40-59 years) and older adults (>59 years) who participated in the 2011-2016 US National Health and Nutrition Examination Surveys (NHANES) or the 2013-2015 South Korean NHANES. The exposure was food insecurity severity (food secure/early-stage food insecurity/middle-stage or severe food insecurity) assessed using the 18-item US Household Food Security Survey Module. The two outcomes were any untreated tooth decay and periodontitis measured using the Modified Community Periodontal Index of Treatment Needs. Covariate-adjusted odds ratios (OR) with 95% confidence intervals (CI) were generated using multivariable logistic regression models. RESULTS: Middle or severe food insecurity was associated with significantly higher odds of having untreated tooth decay than no food insecurity, but only among middle-aged adults in the United States (OR: 1.4, 95% CI 1.2, 1.9; P = .037) and Korea (OR = 1.8; 95% CI:1.0, 3.2; P = .036) and older adults in the United States (OR: 2.6, 95% CI 1.7, 4.0; P < .001). The associations between food insecurity and periodontitis were inconsistent across age group and country. CONCLUSION: Differing cultural norms and access to dental services in the United States and South Korea may influence the relationship between food insecurity and oral health. Future research should explore how addressing food insecurity could help to promote the oral health of middle-aged and older adults in diverse sociocultural contexts.

Health insurance is associated with dental care use among university students in Washington State.

BACKGROUND: The goal of this study was to examine the association of health insurance and preventive dental care use among university students. METHODS: This secondary analysis of cross-sectional data focused on students at University of Washington in Washington state (WA) who completed a health insurance survey in 2017 (n = 3768). The exposure was health insurance (private insurance in WA [reference group], not insured, Medicaid or Medicare [public insurance], university insurance, private insurance not in WA, other) and the outcome was receiving a dental cleaning in the past 6 months. Logistic regression was used to generate odds ratios and 95% confidence intervals (CI) adjusted for confounders. RESULTS: About 5% of university students did not have health insurance and 37% did not have a dental cleaning in the past 6 months. Compared to students with private health insurance based in WA, the odds of not receiving a dental cleaning were 3.90 times greater for university students with no health insurance (95% CI 2.74, 5.55; p < .001) and 3.08 times greater for publicly-insured university students (95% CI 2.52, 3.76; p < .001). CONCLUSIONS: University students are at risk for poor oral health behaviors. Those without health insurance and those with public insurance face barriers to preventive dental care. Efforts should be made to connect uninsured university students with insurance, dental services, and other oral health promotion activities.

Effects of Adult Medicaid Dental Benefits Elimination on Child Dental Care Use.

OBJECTIVE: The objective of this study was to examine the effect of adult dental benefit cuts on child dental use in Washington state Medicaid and determine if cuts affect child demographic subgroups differentially. RESEARCH DESIGN: The study used an interrupted time-series methodology to measure differences in child dental use after adult dental benefit elimination and reinstatement. Monthly data came from Washington state Medicaid enrollee and dental claim files from January 2008 to December 2015. SUBJECTS: Medicaid-enrolled children with at least one Medicaid-enrolled adult in the same household were the intervention group, and Medicaid-enrolled children without a Medicaid-enrolled adult in the same household were the control group. MEASURES: The outcome was the monthly proportion of Medicaid-enrolled children with a dental examination per 10,000 Medicaid-enrolled children. RESULTS: After adult dental benefits elimination, dental examinations among children with Medicaid-enrolled adults in the same household gradually decreased, corresponding to 65 fewer dental examinations per 10,000 children per year (5.4 fewer dental examinations per 10,000 children per month; 95% confidence interval: -7.7, -3.1; P =0.006). Adult dental benefits had no effect on dental examination for children without a Medicaid-enrolled adult in the same household. Dental examinations for children with a Medicaid-enrolled adult in the same household continued to gradually decrease after adult benefits reinstatement. Children younger than age 6 were the most adversely impacted by changes to adult Medicaid dental benefits. CONCLUSION: Policymakers should consider the spillover effects and ethical considerations of eliminating adult Medicaid dental benefits on children's access to dental care.

Plan Type and Opioid Prescriptions for Children in Medicaid.

BACKGROUND: Opioids are generally an inappropriate acute pain management strategy in children, particularly because of the risk for diversion and subsequent misuse and abuse. OBJECTIVES: To examine associations between Medicaid plan type [coordinated care organization (CCO), managed care (MC), fee-for-service (FFS)] and whether a child received an opioid prescription. RESEARCH DESIGN: Secondary analysis of Oregon Medicaid data (January 1, 2016 to December 31, 2017). SUBJECTS: Medicaid-enrolled children ages 0-17 (N=200,169). MEASURES: There were 2 outcomes: whether a child received an opioid prescription from (a) any health provider or (b) from a visit to the dentist. Predictor variables included Medicaid plan type, age, sex, race, and ethnicity. RESULTS: About 6.7% of children received an opioid from any health provider and 1.2% received an opioid from a dentist visit. Children in a CCO were significantly more likely than children in a MC (P<0.01) or FFS (P=0.02) plan to receive an opioid from any health provider. Children in a CCO were also significantly more likely than children in MC or FFS to receive an opioid from a dentist visit (P<0.01). CONCLUSIONS: Pediatric opioid prescriptions vary by plan type. Future efforts should identify reasons why Medicaid-enrolled children in a CCO plan are more likely to be prescribed opioids.

Survey and electronic health record-based medication use agreement in children with cystic fibrosis: A retrospective cross-sectional study.

BACKGROUND: Medication use is important to collect accurately in medically complex patients in both clinical and research settings. AIM: We assessed patient-level agreement for medication use between self-reported survey and electronic health record (EHR) for children with cystic fibrosis (CF). METHODS: Our retrospective cross-sectional study focused on children with CF ages 6-20 years from Seattle Children's Hospital in Washington state, USA (N = 85). A self- or parent-reported survey included questions on current use of specific medications and antibiotic use in the past 2 months. We compared survey data with data abstracted from the individual's EHR and derived Cohen's Kappa statistics to estimate the level of agreement between the two methods. RESULTS: Self-reported medication use was generally higher in the survey than in the EHR. The level of agreement ranged from slight for probiotics (74.1% agreement; 95% confidence interval [CI]: 64.6%-83.6%; kappa: 0.07), pancreatic enzymes (80% agreement; 95% CI: 71.3%-88.7%; kappa: 0.12), and vitamin D (55.3% agreement; 95% CI: 44.5%-66.1%; kappa: 0.20) to moderate for chronic azithromycin (80% agreement; 95% CI: 7.13%-88.7%; kappa: 0.50), proton pump inhibitors (76.5% agreement; 95% CI: 67.3%-85.7%; kappa: 0.46), and oral antibiotics (70.6% agreement; 95% CI: 60.7%-80.5%; kappa: 0.42). CONCLUSION: There is considerable heterogeneity in level of agreement in medication use between self-reported survey and EHR data for children with CF. Standardized approaches are needed to improve the accuracy of medication data collected in clinical practice and research.

Oral health behaviours and dental caries in low-income children with special healthcare needs: A prospective observational study.

BACKGROUND: Dental caries is a significant public health problem for low-income children with special healthcare needs (CSHCN). AIM: We evaluated associations between oral health behaviours (eg diet, fluoride, dental care) and dental caries for CSHCN enrolled in Medicaid, a health insurance programme for low-income populations that provides comprehensive dental coverage for children. DESIGN: We recruited 116 CSHCN ages 7-20 years from Medicaid enrolment files in Washington state, USA. Caregivers completed a 166-item questionnaire, and children received a dental screening. The outcome was dental caries, defined as total pre-cavitated, decayed, missing or filled tooth (PDMF) surfaces. We ran log-linear regression models and generated prevalence rate ratios (PRR). RESULTS: The mean age of study participants was 12.4 ± 3.1 years, 41.4% were female, and 38.8% were white. The mean PDMF surfaces were 6.4 ± 9.4 (range: 0-49). Only sugar-sweetened beverage intake was significantly associated with dental caries. CSHCN who consumed >4 sugar-sweetened beverages per week were significantly more likely to have dental caries than those who consumed no sugar-sweetened beverages (PRR: 2.58; 95% CI: 1.37, 4.85; P < .01). CONCLUSION: Sugar-sweetened beverages are an important target for future behavioural interventions aimed at preventing dental caries in low-income CSHCN.

Unstimulated Saliva-Related Caries Risk Factors in Individuals with Cystic Fibrosis: A Cross-Sectional Analysis of Unstimulated Salivary Flow, pH, and Buffering Capacity.

Salivary flow rate, pH, and buffering capacity are associated with dental caries, but studies from the cystic fibrosis (CF) literature are inconclusive regarding these salivary factors and caries. The aim of this study was to evaluate these factors and their associations with dental caries in individuals with CF. Unstimulated whole saliva was collected from individuals aged 6-20 years at Seattle Children's Hospital CF Clinic, USA (n = 83). Salivary flow rate was measured in milliliters per minute. Salivary pH was assessed using a laboratory pH meter. Buffering capacity was assessed by titration with HCl. The outcome measure was caries prevalence, defined as the number of decayed, missing, or filled primary and permanent tooth surfaces. Spearman's rank correlation coefficient and the t test were used to test for bivariate associations. Multiple variable linear regression models were used to (1) run confounder-adjusted analyses and (2) assess for potential interactions. There was no significant association between salivary flow rate or buffering capacity and caries prevalence. There was a significant negative association between salivary pH and caries prevalence, but this association was no longer significant after adjusting for age. There was no significant interaction between salivary flow rate and buffering capacity or between antibiotic use and the 3 salivary factors. Our results indicate that unstimulated salivary factors are not associated with dental caries prevalence in individuals with CF. Future studies should investigate other potential saliva-related caries risk factors in individuals with CF such as cariogenic bacteria levels, salivary host defense peptide levels, and medication use.
