Background: Dental caries is the most common chronic childhood infectious disease and is a serious public health problem affecting both developing and industrialized countries, yet it is preventable in most cases. This study evaluated the potential of screening for dental caries among children using a machine learning algorithm applied to parent perceptions of their child’s oral health assessed by survey. Methods: The sample consisted of 182 parents/caregivers and their children 2–7 years of age living in Los Angeles County. Random forest (a machine learning algorithm) was used to identify survey items that were predictors of active caries and caries experience. We applied a three-fold cross-validation method. A threshold was determined by maximizing the sum of sensitivity and specificity conditional on the sensitivity of at least 70%. The importance of survey items to classifying active caries and caries experience was measured using mean decreased Gini (MDG) and mean decreased accuracy (MDA) coefficients. Results: Survey items that were strong predictors of active caries included parent’s age (MDG = 0.84; MDA = 1.97), unmet needs (MDG = 0.71; MDA = 2.06) and the child being African American (MDG = 0.38; MDA = 1.92). Survey items that were strong predictors of caries experience included parent’s age (MDG = 2.97; MDA = 4.74), child had an oral health problem in the past 12 months (MDG = 2.20; MDA = 4.04) and child had a tooth that hurt (MDG = 1.65; MDA = 3.84). Conclusion: Our findings demonstrate the potential of screening for active caries and caries experience among children using surveys answered by their parents.

Background: The Hispanic population is the largest (18.5%) and fastest growing non‐majority ethnic group in the United States (US), about half of whom are non‐US born, and bears one of the highest oral disease burdens. Most current knowledge around oral health disparities in Hispanic populations examine the individual factors of culture, acculturation, and socioeconomic status. However, the root causes of this inequity; oral health literacy (OHL), social determinants of health (SDOH), structural racism and discrimination (SRD) and the intersectionality among the three, have not been well‐studied. Addressing this critical gap will be central to advancing health equity and reducing oral health‐related disparities in the Hispanic population, especially among immigrant and non‐English speaking Hispanics.Results: Recommendations for future OHL/SDOH/SRD‐related research in oral health targeting Hispanic populations should include: (1) examining the direct and indirect effects of OHL/SDOH/SRD‐related factors and intersectionality, (2) assessing the impact of SRD on oral health using zip‐code level measures, (3) examining the role of OHL and SDOH as potential effect modifiers on the relationship between SRD and oral health outcomes, (4) conducting secondary data analysis to identify demographic, social and structural‐level variables and correlations between and among variables to predict oral health outcomes, and (5) obtaining a deeper understanding of how OHL/SDOH and SRD factors are experienced among Hispanic immigrant and migrant populations.Conclusion: It is hoped these recommendations will lead to a better understanding of the mechanisms through which OHL, SDOH and SRD impact oral health outcomes among the largest minority population in the US so they can be addressed.

Background: Although antiretroviral therapy (ART) is available to treat HIV+ persons and prevent transmission, ineffective delivery of care may delay ART use, impede viral suppression (VS), and contribute to racial/ethnic disparities along the continuum of care. This study tested the effects of a bi-directional laboratory health information exchange (LHIE) intervention on each of these outcomes. Methods: We used a quasi-experimental, interrupted time-series design to examine whether the LHIE intervention improved ART use and VS, and reduced racial/ethnic disparities in these outcomes among HIV+ patients (N = 1181) in a comprehensive HIV/AIDS clinic in Southern California. Main outcome measures were ART pharmacy fill and HIV viral load laboratory data extracted from the medical records over 3 years. Race/ethnicity and an indicator for the intervention (after vs. before) were the main predictors. The analysis involved 3-stage, multivariable logistic regression with generalized estimating equations. Results: Overall, the intervention predicted greater odds of ART use (odds ratio [OR] = 2.50; 95% confidence interval: 2.29 to 2.73; P < 0.001) and VS (OR = 1.12; 95% confidence interval: 1.04 to 1.21; P < 0.05) in the final models that included sociodemographic, behavioral, and clinical covariates. Before the intervention, there were significant black/white disparities in ART use OR = 0.75 (0.58–0.98; P = 0.04) and VS OR = 0.75 (0.61–0.92; P = 0.001). After the intervention, the black/white disparities decreased after adjusting for sociodemographics and the number of HIV care visits, and Latinos had greater odds than whites of ART use and VS, adjusting for covariates. Conclusions: The intervention improved overall ART treatment and VS, and reduced black/white disparities. LHIE interventions may hold promise if implemented among similar patients.

Children living in rural and migrant areas in the United States disproportionately suffer from poor oral health. Additionally, there continues to be a shortage of pediatric dentists practicing in rural/migrant areas. The purpose of this formative research study was to assess whether staff, teachers and families from rural/migrant Head Start/Early Head Start (HS/EHS) programs in California were receptive to oral health online education workshops conducted by pediatric dental residents who were assisted by bilingual (English and Spanish) community oral health workers (COHWs). Our findings suggest that partnering pediatric dental residents with bilingual COHWs to educate HS/EHS teachers, staff and parents on oral health care in rural/migrant areas could result in a rewarding experience for pediatric dentists that might lead them to practice in these communities upon graduation from their residency program. Furthermore, the positive feedback received from the teachers, staff and parents who participated in the workshops indicates they were receptive to receiving oral health information related to oral health literacy from the dental providers and COHWs. COHWs can help increase access to oral health care by serving as a bridge between families and providers by relaying information in a cultural, linguistic and sensitive manner.

(1) Background/Objective: California has one of the highest rates of pediatric dental caries in the nation. One way to combat this problem is through non-dental provider training programs that focus on prevention. However, there are limited data on healthcare provider training program integration and evaluation of oral health curricula focused on prevention of early childhood caries. This study will assess the change in healthcare providers’ attitudes, knowledge, and skills by implementing an interprofessional educational (IPE) oral health curriculum in medicine and nurse practitioner programs at one university in Southern California. (2) Methods: A mixed method design was employed using a pre- and post-educational survey, and end-of-program focus group interviews. Descriptive statistics and paired t-tests were used to assess group differences and thematic analyses for the focus groups. (3) Results: A total of 81 students (14 pediatric medicine residents, 18 pediatric, and 49 family nurse practitioners) completed the curriculum and surveys. Attitudes related to oral hygiene remained unchanged, with the nurse practitioner group showing improved clinical skills (all questions; p < 0.021). Knowledge scores significantly improved across all groups (paired t-test; p < 0.001). All focus groups expressed the helpfulness of the educational modules, the usefulness of the skills learned, and the benefits of IPE activities. (4) Conclusion: Healthcare providers showed improved oral health knowledge and clinical skills acquired through the oral health program and can serve as a model to educate across disciplines on the prevention of early childhood caries.

This study aimed to examine the depression and anxiety among men of color (primarily African American and Latinx) who have sex with men after the lockdown due to the COVID-19 pandemic. Outcomes included 21-item Beck Depression Inventory (BDI), 7-item Generalized Anxiety Disorder (GAD), and a 10-item COVID-related anxiety measure using a modified H1N1-related anxiety question. Independent variables were food insecurity and belief in government efficiency. Data were analyzed by Regression models with random cluster effects. Food insecurity experiences were significantly associated with higher depression (p < 0.001), higher anxiety (p < 0.001), and higher pandemic-related anxiety (p < 0.001). Higher levels of belief in government efficiency were significantly associated with lower depression (p < 0.05), less anxiety (p < 0.05), and less pandemic-related anxiety (p-value < 0.001). These findings emphasize the importance of establishing trust between government and at-risk communities when issuing public health policies, especially during unforeseen circumstances, as well as to ensure basic human rights, such as food security.
