Parental acceptability of silver diamine fluoride: The UK and US experiences.

BACKGROUND: International data suggest that parents may have reservations about the use of silver diamine fluoride (SDF). AIM: The aims of this study were to: (1) examine the acceptance of parents/carers towards the use of SDF for the management of caries in children's primary teeth in secondary care dental settings in the UK and the United States and (2) determine which factors may affect the acceptance of the use of SDF. DESIGN: This was a cross-sectional questionnaire of SDF acceptability, completed by parents of young children. It was validated and adapted to local populations. Data were analysed with descriptive and inferential statistics. RESULTS: Of the 113 Sheffield parents, 73% reported that they would accept SDF treatment of children's posterior teeth, with 58% reporting this for anterior teeth. Parents having less concern about posterior aesthetics had a statistically significant effect on reported acceptance of SDF (p = .013). In the Colorado sample (n = 104), 72% reported that they would accept SDF on posterior teeth, and 58% reported that they would accept SDF on anterior teeth. Concerns about aesthetics had an effect on decreasing SDF acceptance overall (p = .0065) in anterior (p = .023) and posterior teeth (p = .108). CONCLUSION: The majority of parents in the two study populations accepted the treatment using SDF. However, concern about aesthetics had an influence on acceptability.

Pathways Through Which Health Literacy Is Linked to Parental Oral Health Behavior in an American Indian Tribe.

BACKGROUND: Health literacy (HL) is the "ability to find, understand, evaluate and put information to use to improve decision making and, ultimately, improve health and quality of life." Parents with limited HL are less likely to follow recommended parental oral health behaviors. PURPOSE: We tested a theoretical framework designed to clarify mechanisms through which HL may influence parental oral health behavior. The framework proposed that HL: (a) has a direct effect on parental oral health knowledge, beliefs (i.e. self-efficacy; perceived susceptibility, severity, benefits, barriers), and behavior; (b) influences beliefs indirectly through knowledge; and (c) influences behavior indirectly through knowledge and beliefs. METHODS: We analyzed cross-sectional data from a randomized controlled trial designed to reduce dental decay in American Indian children (N = 521). Parents completed survey questions assessing sociodemographic characteristics, HL, and parental oral health knowledge, beliefs, and behavior. Path analysis was used to test the framework. RESULTS: HL exerted significant direct effects on knowledge and beliefs but not behavior. HL had significant indirect effects on all beliefs through knowledge. Significant indirect effects of HL on behavior occurred through self-efficacy (estimate: 0.99, 95% CI: 0.42, 1.83, p = .005), perceived barriers (estimate: 0.73, 95% CI: 0.29, 1.43, p = .010), knowledge to self-efficacy (estimate: 0.57, 95% CI: .31, 0.98, p = .001), and knowledge to perceived barriers (estimate: 0.24, 95% CI: 0.09, 0.47, p = .012). CONCLUSIONS: HL exerted an indirect effect on parental oral health behavior, with knowledge, self-efficacy, and perceived barriers being the primary constructs linking HL to behavior.

Association between maternal acculturation and health beliefs related to oral health of Latino children.

BACKGROUND: This report is presenting the association of maternal acculturation, measured by preferred language, and oral health-related psychosocial measures in an urban Latino population. METHODS: A cross-sectional survey was conducted with 100 mother-child dyads from the Dental Center at the Children's Hospital Colorado, the University of Colorado. A portion of Basic Research Factors Questionnaire capturing information about parental dental knowledge, attitudes, behavior and psychosocial measures was used to collect data from the participating mothers. Descriptive statistics were calculated for demographics and psychosocial measures by acculturation. A univariate linear regression model was performed for each measure by preferred language for primary analysis followed by adjusted model adjusting for parent's education. RESULTS: The mean age of the children was 3.99 years (SD = 1.11), and that of the mother was 29.54 years (SD = 9.62). Dental caries, measured as dmfs, was significantly higher in children of Spanish-speaking mothers compared to children of English-speaking mothers. English-speaking mothers had higher mean scores of oral health knowledge, oral health behaviors, knowledge on dental utilization, self-efficacy, and Oral Health Locus of Control as compared to Spanish-speaking mothers. Univariate analysis demonstrated significant association for preference for Spanish language with knowledge on dental utilization, maternal self-efficacy, perceived susceptibility and perceived barriers. The effect of language was attenuated, but significant, for each of these variables after adjusting for parent's education. CONCLUSION: This study reported that higher acculturation measured by a preference for the English language had a positive association with oral health outcomes in children. Spanish-speaking mothers perceived that their children were less susceptible to caries. Additionally, they perceived barriers in visiting the dentist for preventive visits.

Absence of Fluoride Varnish-Related Adverse Events in Caries Prevention Trials in Young Children, United States.

INTRODUCTION: Fluoride varnish is an effective prevention intervention for caries in young children. Its routine use in clinical care is supported by meta-analyses and recommended by clinical guidelines, including the US Preventive Services Task Force (B rating). This report is the first prospective systematic assessment of adverse events related to fluoride varnish treatment in young children. METHODS: We determined the incidence of adverse events related to fluoride varnish treatment in 3 clinical trials on the prevention of early childhood caries, conducted under the auspices of the Early Childhood Caries Collaborating Centers, an initiative sponsored by the National Institute of Dental and Craniofacial Research. Each trial incorporated use of fluoride varnish in its protocol and systematically queried all children's parents or legal guardians about the occurrence of acute adverse events after each fluoride varnish treatment. RESULTS: A total of 2,424 community-dwelling, dentate children aged 0 to 5 years were enrolled and followed for up to 3 years. These children received a cumulative total of 10,249 fluoride varnish treatments. On average, each child received 4.2 fluoride varnish treatments. We found zero fluoride varnish-related adverse events. CONCLUSION: Fluoride varnish was not associated with treatment-related adverse events in young children. Our findings support its safety as an effective prevention intervention for caries in young children.

A Comparative Analysis of Oral Health on the Santo Domingo Pueblo Reservation.

The study was done to compare oral health data from a tribe in a relatively accessible location between Santa Fe and Albuquerque, New Mexico to national American Indian data and broader US data sets. Participants (N = 399) were recruited via random sampling of housing units. Dental health measures included DMFT/dmft and dental sealants. Comparisons were made using data from large-scale oral health surveillance studies. There was no difference in oral health for 3-5 year olds compared to a recent study of AI/AN preschool children. Compared to the general US population, Santo Domingo Pueblo children and adults showed higher prevalence of untreated decay. Children ages 5-19 had higher rates of sealant retention on permanent teeth, and adults showed lower prevalence of complete tooth retention. The children ages 5-19 and 12-19 with at least one sealant have significantly lower DMFT and less untreated decay than those without sealants. However, the percentage of children with and without sealants who had untreated decay was still more than two times higher than the general US population. Oral health of American Indian children and adults in Santo Domingo Pueblo was worse compared to the general US population but similar to previous results reported for the same Indian Health Service Area even though their location is less isolated than many other tribes.

Association of parental social support and dental caries in hispanic children.

This study describes social support of Hispanic parents and the correlation with dental caries in their children. A cross-sectional study design was utilized to assess the 157 parent-child triads recruited from the Children's Hospital Colorado Dental Clinic. The Basic Research Factors Questionnaire (BRFQ) survey was utilized to assess parents' oral health knowledge, attitudes, behavior, and other psychosocial measures with social support as the main predictor variable. Bivariate associations between the independent variables and dmfs were conducted. Independent variables with a bivariate association of p ≤ 0.2 for the outcome variable were included in the multivariable linear regression model. Dental caries in children was significantly associated with less overall parental social support (ß = -10.10, p = 0.03). Overall social support was divided into four sub-categories: errand help, money help, childcare help, and transportation help. Dental caries decreased by 7.70 units for every 1-unit increase in transportation help (ß = -7.70, p = 0.03). A significant association was observed between parental knowledge on dental utilization and dmfs (ß = -2.70, p = 0.04). In the multivariable linear regression model, caries was significantly associated with social support (ß = -11.18, p = 0.02) and knowledge on dental utilization (ß = -3.84, p = 0.01). The study concludes that a higher level of social support and knowledge on dental utilization for Hispanic parents is correlated with lower rates of dental caries in their children.

Patterns of Change in Parental Health Literacy in Relation to Children's Oral Health.

BACKGROUND: Although health literacy (HL) skills may change over time, most research treats HL as a constant, using baseline HL to predict other health-related constructs. Few studies have explored change in HL over time. OBJECTIVE: We examined person-level differences in HL trajectories. We identified subgroups (latent classes) based on longitudinal assessments of HL and examined the association of class membership with demographic and oral health variables. METHODS: We used four measurement waves of parental HL data, reflecting the risk of limited HL, collected as part of an intervention to reduce dental decay in American Indian children (N = 579 parent-child dyads at baseline). Repeated measures latent class analysis (RMLCA) models were estimated to identify subgroups of HL trajectories over time. We examined class membership in association with baseline demographics and with 36-month assessments of parental oral health knowledge, beliefs, and behaviors as well as pediatric oral health. KEY RESULTS: A four-class model best fit the data. The largest class (high HL; 49.7% of the sample) was characterized by high levels of HL at all waves. A second class (improving HL; 17.7%) improved over all waves. The remaining two classes were characterized as moderate HL (20%) and low HL (12.6%) and maintained relatively stable HL levels over time. Higher educational attainment was associated with membership in the high HL and improving HL classes. Older age among this young-adult sample and higher income also were associated with high HL class membership. Parents in the high HL and improving HL classes exhibited more favorable performance on measures of oral health knowledge, beliefs, and behavioral adherence than did those in the other classes. Class membership was not associated with pediatric oral health. CONCLUSIONS: RMLCA demonstrated person-level variability in HL trajectories. Longitudinal patterns were associated with baseline demographics and prospectively with parental oral health knowledge, beliefs, and behaviors, but not with pediatric oral health.

Association of Acculturation and Latino Parents' Oral Health Beliefs and Knowledge.

The purpose of our study was to explore the association of acculturation and Latino parent behavioral and psychosocial characteristics. A cross-sectional survey was conducted with 197 parent-children triads. Participating parents completed survey questions encompassing oral health knowledge, behaviors and beliefs from a validated oral health instrument. The mean score for acculturation in this sample was 3.8, where acculturation was dichotomized to a categorical variable. The bivariate associations between the independent variables (caregiver psychosocial factors and socio-economic factors (SES) factors) and acculturation (more/less acculturated) were conducted using logistic regression analysis, and for the final model a multivariate logistic regression model was used. In the bivariate analyses, less acculturated parents reported lower oral health knowledge (p = 0.02), higher social support (p = 0.028) and chronic stress (p = 0.015) and lower perceived susceptibility to dental caries in their children (p = 0.039). The bivariate analysis demonstrated that less acculturated parents had less education and employment (p < 0.0001) than more acculturated parents. The multivariate logistic model demonstrated that social support (p = 0.028), chronic stress (p = 0.015) and health beliefs as barriers to access dental care (p = 0.039) were higher in less acculturated parents compared to more acculturated parents. Less acculturated parents demonstrated lower oral health knowledge, higher stress and more barriers to accessing oral health care for their children. Oral health interventions for Latino families should incorporate strategies that include consideration of parental oral health beliefs.

Influence of Parental Health Literacy on Change over Time in the Oral Health of American Indian Children.

In cross-sectional studies, parental health literacy (HL) is associated with children's oral health. It is unclear, however, whether HL influences pediatric outcomes. We examined the relationship of HL with change over time in parental oral health knowledge, beliefs, and behaviors, as well as pediatric oral health outcomes. We used longitudinal data from a study designed to reduce dental decay in American Indian children (N = 579). At baseline and annually for three years, parents answered questions assessing HL; oral health knowledge, beliefs, and behaviors; and pediatric oral health status. The number of decayed, missing, and filled tooth surfaces (dmfs) was computed based on annual dental evaluations. Linear mixed models showed that HL was significantly associated with all constructs, except dmfs, at their reference time points and persistently across the three-year study period. HL predicted change over time in only one variable, parents' belief that children's oral health is determined by chance or luck. HL is strongly associated with oral health knowledge, beliefs, behaviors, and status prospectively but is not a key driver of change over time in these oral health constructs.

Longitudinal Association of Health Literacy with Parental Oral Health Behavior.

BACKGROUND: Prior studies suggest that parents with limited health literacy (HL) may be less likely to engage in oral health practices known to protect children's oral health. Earlier work has relied on cross-sectional data, however, so it is unclear whether HL influences parental behavior or is merely correlated with it. OBJECTIVE: We sought to clarify the impact of HL on subsequent adherence to parental oral health practices. METHODS: This secondary analysis used survey data from a randomized controlled trial designed to reduce dental decay in American Indian children (N = 579). We used path analysis to test a theoretical framework developed to clarify the mechanisms through which HL might influence parental oral health behavior. The framework proposed that HL (1) has a direct effect on parental oral health knowledge, beliefs (i.e., self-efficacy, perceived susceptibility, perceived severity, perceived barriers, perceived benefits), and behavior; (2) has an indirect effect on beliefs through knowledge; and (3) has an indirect effect on behavior through knowledge and beliefs. To test expectations regarding the temporal precedence of the constructs, we examined the association of HL at baseline with knowledge at the 12-month time point, beliefs at 24 months, and behavior at 36 months. KEY RESULTS: HL had significant direct effects on knowledge and specific beliefs (i.e., self-efficacy, perceived susceptibility, perceived barriers), but not on behavior. HL had significant indirect effects on beliefs-except perceived susceptibility-through knowledge. HL had significant indirect effects on behavior, through knowledge and beliefs. Both HL and knowledge had significant total effects on subsequent parental oral health behavior. CONCLUSIONS: HL influenced behavior measured 3 years later through its impact on parental oral health knowledge and beliefs. Our results highlight the importance of addressing HL in development of oral health promotion efforts aimed at protecting the teeth of young Native children. [HLRP: Health Literacy Research and Practice. 2021;5(4):e333-e341.] Plain Language Summary: It is unclear whether HL influences how parents care for their children's teeth. We analyzed data from a project to reduce dental decay in children. We found that HL impacted parents' oral health knowledge, beliefs, and behavior at later points in time. This suggests that HL may influence development of knowledge and beliefs that support positive behavior.

Parental Ethnic Identity and Its Influence on Children's Oral Health in American Indian Families.

OBJECTIVES: To examine the relationship between ethnic identity and oral health knowledge, beliefs, behavior, and outcomes in American Indian families. METHODS: Secondary data were analyzed for 579 parent-child dyads in a randomized controlled trial aimed at reducing early childhood caries in a Northern Plains tribal community. Data included demographic characteristics; parental ethnic identity; oral health knowledge, beliefs, and behavior; and parental/pediatric oral health outcomes. Ethnic identity was assessed using two measures: perceived importance of tribal identity and tribal language proficiency. We examined the association of baseline ethnic identity with baseline and longitudinal oral health measures. RESULTS: At baseline, importance of tribal identity was significantly associated with several oral health beliefs, and one's locus of control measure (external-chance). Baseline scores on importance of tribal identity were also associated with one's oral heath belief (perceived severity), the same locus of control measure, and oral health knowledge and behavior over the three years of study follow up. Tribal language proficiency was not associated with any study measures at baseline, although it was associated with parental oral health status over the three years. CONCLUSIONS: Ethnic identity was associated with a range of oral health constructs expected to influence American Indian children's oral health.

Health Literacy and Parental Oral Health Knowledge, Beliefs, Behavior, and Status Among Parents of American Indian Newborns.

OBJECTIVE: To examine the relationship between health literacy (HL) and parental oral health knowledge, beliefs, behavior, and self-reported oral health status (OHS) among parents of American Indian (AI) children. METHODS: This analysis used baseline data from a randomized controlled trial that tested an oral health intervention with parents of AI newborns. Participants were recruited in parent-child dyads (N = 579). Parents completed items assessing sociodemographic characteristics, HL, and parental oral health knowledge, beliefs, behavior, and self-reported OHS. We examined the correlation of HL with each oral health construct, controlling for parent age and income. RESULTS: On average, parents felt quite confident in their HL skills, performed well on questions assessing parental oral health knowledge, and endorsed beliefs likely to encourage positive parental oral health behaviors (e.g., confidence that one can successfully engage in such behaviors). Parents with more limited HL had significantly less knowledge, perceived cavities to be less severe, perceived more barriers and fewer benefits to recommended oral health behaviors, were less confident they could engage in these behaviors, and were more likely to believe their children's oral health was under the control of the dentist or a matter of chance (P values < 0.001). Limited HL was not associated with behavior (P > 0.05) but was linked to worse self-reported OHS (P = 0.040). CONCLUSIONS: HL was associated with parental oral health knowledge, beliefs, and self-reported OHS. Oral health education interventions targeting AI families should facilitate development of knowledge and positive oral health beliefs among parents with more limited HL skills.

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.

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.

A comprehensive analysis of normal variation and disease-causing mutations in the human DSPP gene.

Within nine dentin dysplasia (DD) (type II) and dentinogenesis imperfecta (type II and III) patient/families, seven have 1 of 4 net -1 deletions within the approximately 2-kb coding repeat domain of the DSPP gene while the remaining two patients have splice-site mutations. All frameshift mutations are predicted to change the highly soluble DSPP protein into proteins with long hydrophobic amino acid repeats that could interfere with processing of normal DSPP and/or other secreted matrix proteins. We propose that all previously reported missense, nonsense, and splice-site DSPP mutations (all associated with exons 2 and 3) result in dominant phenotypes due to disruption of signal peptide-processing and/or related biochemical events that also result in interference with protein processing. This would bring the currently known dominant forms of the human disease phenotype in agreement with the normal phenotype of the heterozygous null Dspp (-/+) mice. A study of 188 normal human chromosomes revealed a hypervariable DSPP repeat domain with extraordinary rates of change including 20 slip-replication indel events and 37 predominantly C-to-T transition SNPs. The most frequent transition in the primordial 9-basepair (bp) DNA repeat was a sense-strand CpG site while a CpNpG (CAG) transition was the second most frequent SNP. Bisulfite-sequencing of genomic DNA showed that the DSPP repeat can be methylated at both motifs. This suggests that, like plants and some animals, humans methylate some CpNpG sequences. Analysis of 37 haplotypes of the highly variable DSPP gene from geographically diverse people suggests it may be a useful autosomal marker in human migration studies.

Fidelity of motivational interviewing in an American Indian oral health intervention.

OBJECTIVES: Assess fidelity of a motivational interviewing (MI) intervention focused on preventing early childhood caries in a cohort of American Indian mothers with newborns. METHODS: Four interventionists were trained to administer an oral health MI intervention. The MI sessions were audio recorded to enable scoring as part of fidelity studies to assess the interventionist's degree of competence in using MI principles. Evaluation of the interventionists was completed using the Motivational Interviewing Treatment Integrity (MITI) 3.1.1. which assesses global ratings and behaviour counts. Two reviewers evaluated and scored the MI sessions; a random sample of twenty per cent of the total interviews was scored by a trained reviewer and fifty per cent of the randomly selected files scored by an external expert. A total of 225 files were coded by the trained reviewer and 121 files by the external expert. RESULTS: Mean global scores for all interventionists combined were around 4.0 (expert competence). Scores for reflection to question ratios (around 0.6) were below beginner competence. Scores ranged from beginner to expert competence for open-ended questions (54%-56%), complex reflections (38%-43%) and MI-adherent statements (93%-95%). There was variation in competence for the four interventionists when analysed individually. Inter-rater reliability scores for the two reviewers ranged from fair (0.40-0.59) to good (0.60-0.74). The MI interventionist rated the best in the fidelity assessment had the worst study outcomes compared to other interventionists. CONCLUSIONS: Individual interventionists' scores for the MITI global ratings and behaviour counts reflected variation in competence and ranged from below beginner to expert levels. A higher competence level of the interventionist as assessed by the fidelity study was not related to better study outcomes.

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.

The Impact of Maternal Self-Efficacy and Oral Health Beliefs on Early Childhood Caries in Latino Children.

OBJECTIVES: Latino children experience one of the highest rates of early childhood caries requiring interventions based on valid conceptual frameworks. The Health Belief Model has relevance as a predictor of compliance with health recommendations based on perceptions of a health condition and behaviors to avoid the condition. The model encompasses four perceptual constructs (susceptibility, severity, benefits, barriers) and, for complex conditions, includes self-efficacy as an extended model. This study evaluated individual (self-efficacy and health beliefs) and cultural (acculturation status) level factors and the inter-relationship to determine if items assessed for the Extended Health Belief Model (EHBM) were valid measures of maternal factors. METHODS: A cross-sectional study was conducted with 100 mother-child dyads at the Dental Center of Children's Hospital Colorado, Aurora, CO, USA. Participating mothers completed a survey in English or Spanish with items from the Basic Research Factors Questionnaire encompassing sociodemographic characteristics, oral health knowledge and behavior, and psychosocial measures including the EHBM. Language preference was a proxy for maternal acculturation. Children were examined to measure decayed, missing, and filled tooth surfaces. Internal consistency reliability of each subscale was evaluated using Cronbach's alpha. Convergent validity was assessed using linear regression to evaluate the association of the EHBM subscales with oral health-related measures and language preference. RESULTS: The benefits and self-efficacy scales reflected good reliability. Maternal education was the strongest predictor of health beliefs with significant associations for barriers, benefits, and susceptibility. Perceived benefits increased with each additional year in the household. There was a significant association between maternal oral health knowledge and higher perceived benefits and increased self-efficacy, and the same was found for higher knowledge of dental utilization which was also associated with children perceived as having increased susceptibility to early childhood caries. Less acculturated participants perceived more barriers to behavioral adherence and fewer barriers as knowledge increased. As dental utilization knowledge improved for Spanish-speaking participants, they perceived greater benefits from adherent oral health behavior compared to English-speaking participants. CONCLUSION: Items assessed for the EHBM were valid as measures of maternal factors influencing children's oral health outcomes in a Latino population.

Risk and Control of Mosquito-Borne Diseases in Southeast Asian Rubber Plantations.

Unprecedented economic growth in Southeast Asia (SEA) has encouraged the expansion of rubber plantations. This land-use transformation is changing the risk of mosquito-borne diseases. Mature plantations provide ideal habitats for the mosquito vectors of malaria, dengue, and chikungunya. Migrant workers may introduce pathogens into plantation areas, most worryingly artemisinin-resistant malaria parasites. The close proximity of rubber plantations to natural forest also increases the threat from zoonoses, where new vector-borne pathogens spill over from wild animals into humans. There is therefore an urgent need to scale up vector control and access to health care for rubber workers. This requires an intersectoral approach with strong collaboration between the health sector, rubber industry, and local communities.

Validation and Impact of Caregivers' Oral Health Knowledge and Behavior on Children's Oral Health Status.

PURPOSE: To validate oral health knowledge and behavior measures from the Basic Research Factors Questionnaire, developed to capture specific themes contributing to children's oral health outcomes and the influence of caregivers. METHODS: Data were collected as part of a randomized clinical trial (n equals 992) aimed at reducing dental caries in young children. Participants were American Indian/Alaska Native caregivers with a three- to five-year-old child enrolled in a Navajo Nation Head Start Center. Caregivers completed the questionnaire at enrollment with concomitant evaluation of children for decayed, missing, and filled tooth surfaces (dmfs). Oral health knowledge and behavior outcomes were compared with convergent measures (participant sociodemographic characteristics, oral health attitudes, and indicators of oral health status). RESULTS: Caregiver oral health knowledge was significantly associated with education, income, oral health behavior, and all but one of the oral health attitude measures. Behavior was significantly associated with several measures of oral health attitudes and all but one measure of oral health status. As the behavior score improved, dmfs scores declined, child/caregiver overall oral health status improved, and pediatric oral health quality of life improved. CONCLUSIONS: Questionnaire measures were valid for predicting specific caregiver factors potentially contributing to children's oral health status.
