Genome-wide DNA methylation analysis in female veterans with military sexual trauma and comorbid PTSD/MDD.

BACKGROUND: Military sexual trauma (MST) is a prevalent issue within the U.S. military. Victims are more likely to develop comorbid diseases such as posttraumatic stress disorder (PTSD) and major depressive disorder (MDD). Nonetheless, not everyone who suffers from MST develops PTSD and/or MDD. DNA methylation, which can regulate gene expression, might give us insight into the molecular mechanisms behind this discrepancy. Therefore, we sought to identify genomic loci and enriched biological pathways that differ between patients with and without MST, PTSD, and MDD. METHODS: Saliva samples were collected from 113 female veterans. Following DNA extraction and processing, DNA methylation levels were measured through the Infinium HumanMethylationEPIC BeadChip array. We used limma and bump hunting methods to generate the differentially methylated positions and differentially methylated regions (DMRs), respectively. Concurrently, we used Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genome to find enriched pathways. RESULTS: A DMR close to the transcription start site of ZFP57 was differentially methylated between subjects with and without PTSD, replicating previous findings and emphasizing the potential role of ZFP57 in PTSD susceptibility. In the pathway analyses, none survived multiple correction, although top GO terms included some potentially relevant to MST, PTSD, and MDD etiology. CONCLUSION: We conducted one of the first DNA methylation analyses investigating MST along with PTSD and MDD. In addition, we found one DMR near ZFP57 to be associated with PTSD. The replication of this finding indicates further investigation of ZFP57 in PTSD may be warranted.

Does oral health goal setting during medical visits improve parents' oral health behaviors?

OBJECTIVES: The Rocky Mountain Network for Oral Health (RoMoNOH) promotes the delivery of preventive oral health services (POHS) to children receiving care at community health centers (CHCs) in Arizona, Colorado, Montana, and Wyoming. One POHS is oral health goal setting (OHGS). This study aimed to evaluate the effect of OHGS during medical visits on parent/caregiver-reported oral health behaviors (OHBs). METHODS: The RoMoNOH implementation team trained CHC healthcare providers in POHS, including caries risk assessment, oral health education, fluoride varnish application, dental referrals, and parent/caregiver oral health engagement. To promote parents' oral health engagement, healthcare providers were trained in motivational interviewing (MI) with OHGS at medical visits. To evaluate the impact of MI with OHGS on parent/caregiver OHBs, a healthcare team member invited parents/caregivers to complete a baseline survey after their medical visits. The evaluation team sent a follow-up survey after 10-14 days. The surveys measured parents/caregivers' goals, confidence in goal attainment, OHBs, and sociodemographics; the follow-up survey also measured OHGS attainment. Improvement in parent/caregiver-reported OHBs was tested with a paired t-test and unadjusted and adjusted multiple linear regression. RESULTS: In total, 426 parents/caregivers completed the baseline survey; 184 completed both surveys. OHBs, including toothbrushing frequency, stopping bed bottles, drinking tap water, and brushing with fluoride toothpaste improved over the evaluation interval. After adjusting for covariates, brushing with fluoride toothpaste (p = 0.01), drinking tap water (p = 0.03), and removing bed bottles (p = 0.03) improved significantly. CONCLUSION: MI with OHGS with parents/caregivers during medical visits has potential to improve OHBs on behalf of their children.

Embedding Dental Hygienists into Medical Care Teams: Implementation and evaluation of a medical-dental integration approach in Colorado.

This case report describes the implementation approach and evaluation of a medical-dental integration (MDI) project in Colorado that embedded dental hygienists (DHs) into 10 medical practice settings. Through the MDI Learning Collaborative, DHs were integrated into primary care medical care practices to provide full-scope dental hygiene care to patients. Dental hygienists were trained to collect quality-improvement metrics on all encounters, including untreated tooth decay, and referred patients with restorative needs to partnering dentists. Cross-sectional, aggregated clinic-level oral health metrics were submitted monthly from 2019-2022. Descriptive statistics were used to describe the population receiving MDI care and interviews were conducted with MDI staff to describe their perspectives on this approach to comprehensive care. A logistic regression model, adjusted for time and practice, compared untreated dental caries in established vs new MDI patient-visits. From 2019-2021, integrated DHs completed 13,458 visits to low-income patients, Medicaid (70%, n=9,421), uninsured (24%, n=3,230), SCHIP (3%, n=404), private (3%, n=404), of various ages: 0-5 (29%, n=3,838), 6-18 (17%, n=2,266), 18-64 (51%, n=6,825), >65 (4%, n=529). A total of 912 visits were provided to pregnant patients. Services included caries risk assessment (n=9,329), fluoride varnish (n=6,722), dental sealants (n=1,391), silver diamine fluoride (n=382), x-rays (n=5,465) and scaling/root-planing (n=2,882). Improvement was found in untreated decay of established vs. new patient-visits in four of the practices. Dental hygienists integrated into medical teams provided full-scope dental hygiene care to patients and expanded access to dental services. Medical-dental integration (MDI) care was variably associated with reduction in untreated decay. Integrating dental hygienists into primary care medical practices has potential to improve oral health-related outcomes, however access to restorative dental care remains a challenge.

A multimodal deep learning model to infer cell-type-specific functional gene networks.

BACKGROUND: Functional gene networks (FGNs) capture functional relationships among genes that vary across tissues and cell types. Construction of cell-type-specific FGNs enables the understanding of cell-type-specific functional gene relationships and insights into genetic mechanisms of human diseases in disease-relevant cell types. However, most existing FGNs were developed without consideration of specific cell types within tissues. RESULTS: In this study, we created a multimodal deep learning model (MDLCN) to predict cell-type-specific FGNs in the human brain by integrating single-nuclei gene expression data with global protein interaction networks. We systematically evaluated the prediction performance of the MDLCN and showed its superior performance compared to two baseline models (boosting tree and convolutional neural network). Based on the predicted cell-type-specific FGNs, we observed that cell-type marker genes had a higher level of hubness than non-marker genes in their corresponding cell type. Furthermore, we showed that risk genes underlying autism and Alzheimer's disease were more strongly connected in disease-relevant cell types, supporting the cellular context of predicted cell-type-specific FGNs. CONCLUSIONS: Our study proposes a powerful deep learning approach (MDLCN) to predict FGNs underlying a diverse set of cell types in human brain. The MDLCN model enhances prediction accuracy of cell-type-specific FGNs compared to single modality convolutional neural network (CNN) and boosting tree models, as shown by higher areas under both receiver operating characteristic (ROC) and precision-recall curves for different levels of independent test datasets. The predicted FGNs also show evidence for the cellular context and distinct topological features (i.e. higher hubness and topological score) of cell-type marker genes. Moreover, we observed stronger modularity among disease-associated risk genes in FGNs of disease-relevant cell types. For example, the strength of connectivity among autism risk genes was stronger in neurons, but risk genes underlying Alzheimer's disease were more connected in microglia.

Deep learning predicts DNA methylation regulatory variants in the human brain and elucidates the genetics of psychiatric disorders.

There is growing evidence for the role of DNA methylation (DNAm) quantitative trait loci (mQTLs) in the genetics of complex traits, including psychiatric disorders. However, due to extensive linkage disequilibrium (LD) of the genome, it is challenging to identify causal genetic variations that drive DNAm levels by population-based genetic association studies. This limits the utility of mQTLs for fine-mapping risk loci underlying psychiatric disorders identified by genome-wide association studies (GWAS). Here we present INTERACT, a deep learning model that integrates convolutional neural networks with transformer, to predict effects of genetic variations on DNAm levels at CpG sites in the human brain. We show that INTERACT-derived DNAm regulatory variants are not confounded by LD, are concentrated in regulatory genomic regions in the human brain, and are convergent with mQTL evidence from genetic association analysis. We further demonstrate that predicted DNAm regulatory variants are enriched for heritability of brain-related traits and improve polygenic risk prediction for schizophrenia across diverse ancestry samples. Finally, we applied predicted DNAm regulatory variants for fine-mapping schizophrenia GWAS risk loci to identify potential novel risk genes. Our study shows the power of a deep learning approach to identify functional regulatory variants that may elucidate the genetic basis of complex traits.

Incorporating Oral Health into Pediatric Practice: National Trends 2008, 2012, 2018.

OBJECTIVE: Oral health is a critical component of children's overall health, but past research has found that pediatricians report barriers to implementing oral health into practice. Recently, policies have further delineated the importance of oral health in primary medical care. We sought to determine how pediatricians' practices and perceived barriers related to oral health involvement have changed since 2008. METHODS: There have been 3 nationally representative, cross-sectional, oral-health-focused periodic surveys of US American Academy of Pediatrics (AAP) members who provide health supervision: in 2008 (n = 1104; response rate (rr) = 69%), 2012 (n = 646; rr = 48%), and 2018 (n = 485; rr = 48%). The surveys asked about frequency of performing oral health tasks in children 3 years and younger, self-rated ability to perform these tasks, and attitudes about and barriers to oral health involvement. Predicted values from separate multivariable logistic regression models examined the independent effect of survey year. RESULTS: In 2018, pediatricians reported they were more likely to provide fluoride varnish and dental referrals at a younger age and less likely to complete a caries risk assessment or oral examination. They reported diminished barriers to incorporating oral health into pediatric practice. Other oral health activities, notably the oral screening examination and caries risk assessment, remain underutilized by pediatricians. CONCLUSIONS: From 2008 to 2018, more pediatricians reported performing a range of oral health tasks with fewer reported barriers. Ongoing efforts are needed to increase pediatricians' attention to oral screening examinations and caries risk assessments for all pediatric patients beginning in infancy, and to promote further use of fluoride varnish.

Early Childhood Caries in Indigenous Communities.

The oral health of Indigenous children of Canada (First Nations, Inuit, and Métis) and the United States (American Indian and Alaska native) is a major child health disparity when compared with the general population of both countries. Early childhood caries (ECC) occurs in Indigenous children at an earlier age, with a higher prevalence, and at much greater severity than in the general population. ECC results in adverse oral health, affecting childhood health and well-being, and may result in high rates of costly surgical treatment under general anesthesia. ECC is an infectious disease that is influenced by multiple factors, but the social determinants of health are particularly important. This policy statement includes recommendations for preventive and clinical oral health care for infants, toddlers, preschool-aged children, and pregnant women by primary health care providers. It also addresses community-based health-promotion initiatives and access to dental care for Indigenous children. This policy statement encourages oral health interventions at early ages in Indigenous children, including referral to dental care for the use of sealants, interim therapeutic restorations, and silver diamine fluoride. Further community-based research on the microbiology, epidemiology, prevention, and management of ECC in Indigenous communities is also needed to reduce the dismally high rate of caries in this population.

The relationship between DNA methylation in neurotrophic genes and age as evidenced from three independent cohorts: differences by delirium status.

We previously reported the association between DNA methylation (DNAm) of pro-inflammatory cytokine genes and age. In addition, neurotrophic factors are known to be associated with age and neurocognitive disorders. Therefore, we hypothesized that DNAm of neurotrophic genes change with age, especially in delirium patients. DNAm was analyzed using the Illumina HumanMethylation450 or HumanMethylationEPIC BeadChip Kit in 3 independent cohorts: blood from 383 Grady Trauma Project subjects, brain from 21 neurosurgery patients, and blood from 87 inpatients with and without delirium. Both blood and brain samples showed that most of the DNAm of neurotrophic genes were positively correlated with age. Furthermore, DNAm of neurotrophic genes was more positively correlated with age in delirium cases than in non-delirium controls. These findings support our hypothesis that the neurotrophic genes may be epigenetically modulated with age, and this process may be contributing to the pathophysiology of delirium.

Validation of Psychosocial Measures Assessing American Indian Parental Beliefs Related to Control over Their Children's Oral Health.

OBJECTIVES: To validate questionnaire items assessing American Indian (AI) parental beliefs regarding control over their children's oral health within the context of psychosocial measures and children's oral health status. METHODS: Baseline questionnaire data were collected as part of a randomized controlled trial (n = 1016) addressing early childhood caries. Participants were AI parents with preschool-age children in the Navajo Nation Head Start program. Questionnaire items assessed parental oral health locus of control (OHLOC) and agreement with beliefs indicating that they were in control of their children's oral health (internal), the dentist was in control (external powerful others), or children's oral health was a matter of chance (external chance). Exploratory factor analysis was conducted, and convergent validity was assessed using linear regression. RESULTS: Parents with more education (p < 0.0001) and income (p = 0.001) had higher scores for internal OHLOC. Higher internal OHLOC scores were associated with higher scores on knowledge (p < 0.0001), perceived seriousness and benefits (p < 0.0001), higher self-efficacy, importance, sense of coherence (p < 0.0001 for all), and lower scores for perceived barriers (p < 0.0001) and distress (p = 0.01). Higher scores for both types of external OHLOC were associated with lower scores on knowledge (p < 0.0001), perceived seriousness (p < 0.0001), and higher scores on perceived susceptibility (p = 0.01 external chance; <0.0001 powerful others) and barriers (<0.0001). Higher scores for external powerful others were associated with lower scores for importance (p = 0.04) and sense of coherence (p = 0.03). Significant associations were not found for OHLOC beliefs and children's oral health status. CONCLUSIONS: Questionnaire items addressing OHLOC functioned in accordance with the theoretical framework in AI participants.

Genome-wide DNA methylation investigation of glucocorticoid exposure within buccal samples.

AIM: Glucocorticoids play a major role in regulating the stress response, and an imbalance of glucocorticoids has been implicated in stress-related disorders. Within mouse models, CpGs across the genome have been shown to be differentially methylated in response to glucocorticoid treatment, and using the Infinium 27K array, it was shown that humans given synthetic glucocorticoids had DNA methylation (DNAm) changes in blood. However, further investigation of the extent to which glucocorticoids affect DNAm across a larger proportion of the genome is needed. METHODS: Buccal samples were collected before and after synthetic glucocorticoid treatment in the context of a dental procedure. This included 30 tooth extraction surgery patients who received 10 mg of dexamethasone. Genome-wide DNAm was assessed with the Infinium HumanMethylationEPIC array. RESULTS: Five CpGs showed genome-wide significant DNAm changes that were >10%. These differentially methylated CpGs were in or nearest the following genes: ZNF438, KLHDC10, miR-544 or CRABP1, DPH5, and WDFY2. Using previously published datasets of human blood gene expression changes following dexamethasone exposure, a significant proportion of genes with false-discovery-rate-adjusted significant CpGs were also differentially expressed. A pathway analysis of the genes with false-discovery-rate-adjusted significant CpGs revealed significant enrichment of olfactory transduction, pentose and glucuronate interconversions, ascorbate and aldarate metabolism, and steroid hormone biosynthesis pathways. CONCLUSION: High-dose synthetic glucocorticoid administration in the setting of a dental procedure was significantly associated with DNAm changes within buccal samples. These findings are consistent with prior findings of an influence of glucocorticoids on DNAm in humans.

Association of Ethnic Identity with Oral Health Knowledge, Attitudes, Behavior, and Outcomes on the Navajo Nation.

American Indians and Alaska Natives (AI/ANs) experience poor oral health. Children and adults living on the Navajo Nation have a particularly high rate of dental decay. The literature suggests that health outcomes are often associated with the strength of one's ethnic identity. We investigated the association of ethnic identity among Native parents with oral health knowledge, attitudes, behavior, and outcomes. Analyses used baseline data from a randomized controlled trial designed to reduce dental decay among AI/AN preschoolers enrolled in the Navajo Nation Head Start Program. Greater perceived importance of ethnic identity was associated with better oral health knowledge and attitudes but was unassociated with oral health behavior and was linked to worse oral health status. Parents who were better able to speak their tribal language had greater confidence in their ability to manage their children's oral health, engaged in better oral health behavior, and reported better parental oral health status.

Genome-wide DNA methylation comparison between live human brain and peripheral tissues within individuals.

Differential DNA methylation in the brain is associated with many psychiatric diseases, but access to brain tissues is essentially limited to postmortem samples. The use of surrogate tissues has become common in identifying methylation changes associated with psychiatric disease. In this study, we determined the extent to which peripheral tissues can be used as surrogates for DNA methylation in the brain. Blood, saliva, buccal, and live brain tissue samples from 27 patients with medically intractable epilepsy undergoing brain resection were collected (age range 5-61 years). Genome-wide methylation was assessed with the Infinium HumanMethylation450 (n = 12) and HumanMethylationEPIC BeadChip arrays (n = 21). For the EPIC methylation data averaged for each CpG across subjects, the saliva-brain correlation (r = 0.90) was higher than that for blood-brain (r = 0.86) and buccal-brain (r = 0.85) comparisons. However, within individual CpGs, blood had the highest proportion of CpGs correlated to brain at nominally significant levels (20.8%), as compared to buccal tissue (17.4%) and saliva (15.1%). For each CpG and each gene, levels of brain-peripheral tissue correlation varied widely. This indicates that to determine the most useful surrogate tissue for representing brain DNA methylation, the patterns specific to the genomic region of interest must be considered. To assist in that objective, we have developed a website, IMAGE-CpG, that allows researchers to interrogate DNA methylation levels and degree of cross-tissue correlation in user-defined locations across the genome.

Epigenetics of Delirium and Aging: Potential Role of DNA Methylation Change on Cytokine Genes in Glia and Blood Along With Aging.

Background: Delirium in elderly patients is common and dangerous. Major risk factors include aging and exogenous insults, such as infection or surgery. In animal models, aging enhances pro-inflammatory cytokine release from microglia in response to exogenous insults. The epigenetic mechanism DNA methylation (DNAm) regulates gene expression and changes with age. Older individuals may have methylation changes that influence the increased cytokine upon insult, but the degree to which aging affects DNAm of cytokine genes is not fully understood. Methods: The relationship between DNAm and aging of pro-inflammatory cytokine genes (TNF-alpha, IL1-beta, IL-6) was investigated using methylation array data in two cohorts. Brain and blood samples were collected from a neurosurgery cohort (NSG) of 21 subjects who underwent brain resection. A second cohort, the Grady Trauma Project (GTP), included blood samples from 265 subjects. Results: In the NSG cohort, a significant negative correlation between age and DNAm in brain was found at a CpG in IL-6. With the GTP dataset, significant negative correlations between age and DNAm were seen at most of the CpGs in TNF-alpha. Also, TNF-Alpha expression increases with age. These GTP DNAm correlations were also nominally significant in NSG blood samples. In neuronal negative NSG brain tissue, a similar negative trend was observed. Conclusions: With aging, a decrease in DNAm of cytokines gene CpGs in glia and blood was seen. As this can affect their expression, additional research is needed to fully elucidate the role of DNAm in aging and how it may influence the pathogenesis of delirium.

Chronic social stress induces DNA methylation changes at an evolutionary conserved intergenic region in chromosome X.

Chronic stress resulting from prolonged exposure to negative life events increases the risk of mood and anxiety disorders. Although chronic stress can change gene expression relevant for behavior, molecular regulators of this change have not been fully determined. One process that could play a role is DNA methylation, an epigenetic process whereby a methyl group is added onto nucleotides, predominantly cytosine in the CpG context, and which can be induced by chronic stress. It is unknown to what extent chronic social defeat, a model of human social stress, influences DNA methylation patterns across the genome. Our study addressed this question by using a targeted-capture approach called Methyl-Seq to investigate DNA methylation patterns of the dentate gyrus at putative regulatory regions across the mouse genome from mice exposed to 14 days of social defeat. Findings were replicated in independent cohorts by bisulfite-pyrosequencing. Two differentially methylated regions (DMRs) were identified. One DMR was located at intron 9 of Drosha, and it showed reduced methylation in stressed mice. This observation replicated in one of two independent cohorts. A second DMR was identified at an intergenic region of chromosome X, and methylation in this region was increased in stressed mice. This methylation difference replicated in two independent cohorts and in Major Depressive Disorder (MDD) postmortem brains. These results highlight a region not previously known to be differentially methylated by chronic social defeat stress and which may be involved in MDD.

Parental psychosocial factors and childhood caries prevention: Data from an American Indian population.

OBJECTIVES: The objective of this study was to examine the association among psychological and social variables reported by American Indian parents/caregivers of preschool children and changes in their Oral Health Knowledge and Behaviors related to care of their children's teeth. We also investigated the relationship of these factors with progression of caries, as reflected by changes in their children's dmfs. METHODS: The data used for this study were collected at baseline in a clinical trial of an oral health promotion intervention comprising behavioural and clinical interventions for caries prevention delivered by tribal members on a large Southwestern American Indian reservation. Linear regression analyses were performed for changes (baseline to Year 1) in dmfs, Oral Health Knowledge and Oral Health Behavior scores, with baseline psychosocial measures, taken individually, as the independent variables. RESULTS: Parents' attitudes and beliefs were associated with increases in their Oral Health Knowledge and Behavior and also with the progression of caries for their children. When all participants were considered together, increases in children's dmfs were smaller when the caregiver had higher Internal Oral Health Locus of Control (e = -1.33, P = .004), higher Health Literacy (e = -1.55, P < .01), and higher Financial Stability (e = -4.46, P = .03), and lower scores for the Barriers subscale (e = 1.57, P < .01) of the Health Belief Model. For parents in the Intervention group, higher scores on Locus of Control, reflecting beliefs that chance, or other people determine their children's oral health, were associated with larger increases in Oral Health Knowledge (e = 1.73, P = .04) and Behaviors (e = 4.00, P = .005). CONCLUSIONS: Prevention of early childhood caries in American Indian children has proved to be especially challenging. Some of the measures identified in this report may suggest promising directions to prevention through approaches that build on competencies and skills to be learned and used within a context more broadly focused on parenting and management of health and family challenges.

Validity of Measures Assessing Oral Health Beliefs of American Indian Parents.

OBJECTIVES: This aimed to validate measures of constructs included in an extended Health Belief Model (EHBM) addressing oral health beliefs among American Indian (AI) parents. METHODS: Questionnaire data were collected as part of a randomized controlled trial (n = 1016) aimed at reducing childhood caries. Participants were AI parents with a preschool-age child enrolled in the Navajo Nation Head Start program. Questionnaire items addressed five EHBM constructs: perceived susceptibility, severity, barriers, benefits, and parental self-efficacy. Subscales representing each construct underwent reliability and validity testing. Internal consistency reliability of each subscale was evaluated using Cronbach's alpha. Convergent validity was assessed using linear regression to evaluate the association of each EHBM subscale with oral health-related measures. RESULTS: Internal consistency reliability was high for self-efficacy (α = 0.83) and perceived benefits (α = 0.83) compared to remaining EHBM subscales (α < 0.50). Parents with more education (p < 0.0001) and income (p = 0.0002) perceived dental caries as more severe younger parents (ps = 0.02) and those with more education (ps < 0.0001) perceived greater benefits and fewer barriers to following recommended oral health behavior. Female parents (p < 0.0001) and those with more education (p = 0.02) had higher levels of self-efficacy. Parental knowledge was associated with all EHBM measures (ps < 0.0001) excluding perceived susceptibility (p > 0.05). Parents with increased self-efficacy had greater behavioral adherence (p < 0.0001), whereas lower behavioral adherence was associated with parents who reported higher perceived barriers (p < 0.0001). Better pediatric oral health outcomes were associated with higher levels of self-efficacy (p < 0.0001) and lower levels of perceived severity (p = 0.02) and barriers (p = 0.05). CONCLUSIONS: Results support the value of questionnaire items addressing the EHBM subscales, which functioned in a manner consistent with the EHBM theoretical framework in AI participants.

Investigation of differential HDAC4 methylation patterns in eating disorders.

The objective of this study was to investigate the relationship between methylation patterns of the histone deacetylase 4 gene and eating disorders in a site previously associated with anorexia nervosa (AN). Women with AN (N=28) or bulimia nervosa (BN) (N=19) were age-matched and sex-matched to controls (N=45). We obtained saliva-derived DNA and use bisulfite pyrosequencing to examine region-specific methylation differences between cases and controls. The region assayed includes 15 CpGs. We found no significant association between the previously implicated CpG and either AN or BN. We found that three CpGs were nominally associated with AN (P=0.02-0.03); the largest difference was a 9% hypermethylation in AN. One CpG was nominally associated with BN (P=0.04), with 4% hypomethylation. None of these results remained significant after correction for multiple testing. We did not replicate previous findings, though through expanded coverage, we identified additional CpGs that were nominally associated with eating disorders.

Busting the Baby Teeth Myth and Increasing Children's Consumption of Tap Water: Building Public Will for Children's Oral Health in Colorado.

QUESTION: Can a multifaceted statewide communications campaign motivate behavior change in low-income Colorado families to limit children's fruit juice consumption and increase children's consumption of tap water to prevent tooth decay? PURPOSE: Caries is the most common chronic disease of childhood, affecting 40% of kindergartners and 55% of third graders in Colorado. Frequent consumption of 100% fruit juice is linked to childhood caries. The purpose of this campaign, "Cavities Get Around," was to motivate families to limit children's fruit juice consumption and increase consumption of tap water to protect baby teeth from caries, while also building public will for children's oral health. METHODS: The campaign included targeted media, promotores/organizers, and family education. We focused on fruit juice because audience research showed many families view fruit juice as healthy, and it is also a common beverage among young children up to age of 6 years. We also focused on low-socioeconomic status families because data show higher childhood tooth decay rates in this population. To evaluate progress, we conducted identical pre- and post-surveys, each of 600 random low-income parents contacted by landline, mobile telephone, and Internet, allowing for comparative data. RESULTS: Significant progress was achieved compared to 2014 baseline results. Findings from a November 2015 statewide survey of parents included the following: (1) 22-point increase from 2014 in percentage of children regularly drinking tap water (from 41 to 63%). (2) 29-point decrease from 2014 in percentage of respondents who considered fruit juice consumption important to their child's health and nutritional needs (from 72 to 43%). (3) 19-point reduction in fruit juice consumption among young children (from 66% in 2014 to 47% in 2015). (4) 6-point reduction in percentage of parents considering baby teeth "less important" than adult teeth (from 21% in 2014 to 15% in 2015). The campaign also played a role in new state rules prohibiting childcare centers from serving sugar-sweetened beverages and capping 100% juice to twice per week. CONCLUSION: The campaign development, strategies, and evaluation results are instructive for others working on health promotion, childhood nutrition, and education interventions.
