Oral Health Literacy and Outcomes in Rural Wisconsin Adults

Oral healthcare seeking behavior of Malaysian adults in urban and rural areas: findings from the National Health and Morbidity Survey 2019

BACKGROUND

The development and implementation of appropriate strategies to enhance oral health in the community can be aided by an understanding of oral healthcare seeking behavior among urban and rural populations. The purpose of this study was to identify the factors associated with oral healthcare seeking behavior of the Malaysians in urban and rural locations who self-reported dental problems.

METHODS

The National Health and Morbidity Survey 2019, a cross-sectional nationwide household survey that focused on non-institutionalised Malaysians, provided the data for this study on adults in Malaysia who were 18 years of age and older. A two-stage stratified random sampling technique was employed to ensure national representativeness. Data was collected using a multilingual (Malay and English), structured, and validated questionnaire via face-to-face interviews from July to October 2019. The dependent variable was oral healthcare seeking behavior (sought oral healthcare and self-medication). Independent variables were predisposing, enabling and health needs factor based on Andersen's Behavioral Model. Descriptive statistics were used to describe the characteristics and oral healthcare seeking behavior of the respondents. The relationship between the independent and dependent variables were investigated using multivariable logistic regression analysis.

RESULTS

The analysis comprised a total of 10,134 respondents, representing about 18.2 million Malaysian adults aged 18 and above. The overall prevalence of Malaysian adults who self-reported dental problems was low (5.5%) and was slightly higher in the rural than urban population. Almost half sought treatment from healthcare practitioners, and almost a quarter self-medicated. Ethnicity was associated with seeking healthcare and self-medication among urban dwellers. Among the rural population, income level was associated with seeking healthcare while education level was associated with self-medication.

CONCLUSION

Disparities in oral healthcare seeking behaviors exist between Malaysians living in urban and rural areas. Future policies should adopt focused strategies that concentrate on oral healthcare accessibility and health literacy of the vulnerable and rural populations to achieve the best oral healthcare for this population group.

Rural-urban disparities in the incidence and treatment intensity of periodontal disease among patients with diabetes

Background

Diabetes threatens population health, especially in rural areas. Diabetes and periodontal diseases have a bidirectional relationship. A persistence of rural-urban disparities in diabetes may indicate a rural-urban difference in periodontal disease among patients with diabetes; however, the evidence is lacking. This retrospective study aimed to investigate rural-urban discrepancies in the incidence and treatment intensity of periodontal disease among patients who were newly diagnosed with type 2 diabetes in the year 2010.

Methods

The present study was a retrospective cohort design, with two study samples: patients with type 2 diabetes and those who were further diagnosed with periodontal disease. The data sources included the 2010 Diabetes Mellitus Health Database at the patient level, the National Geographic Information Standardization Platform and the Department of Statistics, Ministry of Health and Welfare in Taiwan at the township level. Two dependent variables were a time-to-event outcome for periodontal disease among patients with type 2 diabetes and the treatment intensity measured for patients who were further diagnosed with periodontal disease. The key independent variables are two dummy variables, representing rural and suburban areas, with urban areas as the reference group. The Cox and Poisson regression models were applied for analyses.

Results

Of 68,365 qualified patients, 49% of them had periodontal disease within 10 years after patients were diagnosed with diabetes. Compared to urban patients with diabetes, rural (HR = 0.83, 95% CI: 0.75-0.91) and suburban patients (HR = 0.86, 95% CI: 0.83-0.89) had a lower incidence of periodontal disease. Among 33,612 patients with periodontal disease, rural patients received less treatment intensity of dental care (Rural: RR = 0.87, 95% CI: 0.83, 0.92; suburban: RR = 0.93, 95% CI: 0.92, 0.95) than urban patients.

Conclusion

Given the underutilization of dental care among rural patients with diabetes, a low incidence of periodontal disease indicates potentially undiagnosed periodontal disease, and low treatment intensity signals potentially unmet dental needs. Our findings provide a potential explanation for the persistence of rural-urban disparities in poor diabetes outcomes. Policy interventions to enhance the likelihood of identifying periodontal disease at the early stage for proper treatment would ease the burden of diabetes care and narrow rural-urban discrepancies in diabetes outcomes.

Rural-Urban Differences in Use of Dental Services and Procedures Among Medicare Beneficiaries in 2018

OBJECTIVE

Medicare beneficiaries in rural areas may face challenges in access to dental care. This study assessed rural-urban differences in the use of dental services and dental procedures by Medicare beneficiaries.

METHODS

We obtained data from the 2018 Medicare Current Beneficiary Survey cost and use files. Outcome variables examined in this study were (1) dental visits (yes/no), whether the Medicare beneficiary had ≥1 dental visit in the past year, and (2) dental procedures-preventive (yes/no), restorative (yes/no), and surgical procedures (yes/no)-whether the beneficiary had the procedure in a dental visit. The independent variable was the beneficiary's residence (rural vs urban). We used multiple logistic regression to analyze data and accounted for the survey design of the Medicare Current Beneficiary Survey. The analytic sample included 7377 respondents aged ≥65 years.

RESULTS

Approximately 57.0% (95% CI, 54.9%-59.0%) and 46.4% (95% CI, 41.6%-51.2%) of Medicare beneficiaries in urban and rural communities in the United States had a dental visit in 2018, respectively. Rural beneficiaries were significantly less likely than their urban counterparts to have preventive procedures (adjusted odds ratio = 0.51; 95% CI, 0.36-0.72) but significantly more likely to have restorative procedures (adjusted odds ratio = 1.30; 95% CI, 1.05-1.62).

CONCLUSION

We found significant disparities in use of dental services by Medicare beneficiaries in rural communities. When Medicare beneficiaries in rural areas used dental care, they were less likely than beneficiaries in urban areas to have preventive procedures but more likely to have restorative procedures, suggesting a greater burden of oral health needs among them. Policy research is needed to identify models that can incentivize prevention and improve access to dental care for Medicare beneficiaries in rural communities.

The Association between Electronic Health Literacy and Oral Health Outcomes among Dental Patients in Saudi Arabia: A Cross-Sectional Study

OBJECTIVE

This cross-sectional study aimed to investigate the association between electronic health (eHealth) literacy and oral health outcomes, including the number of teeth and brushing frequency.

METHODS

A total of 478 participants were included in the study and assessed for their eHealth literacy levels. Demographic variables, including age, gender, income, and education, were collected. The participants' number of teeth and brushing frequency were also recorded. Multiple regression analyses were performed to examine the relationship between eHealth literacy and oral health outcomes, adjusting for sociodemographic variables.

RESULTS

The study sample consisted of both males (66.5%) and females (33.5%), with a mean age of 31.95 years. Among the participants, 16.95% were classified as having inadequate eHealth literacy, 24.06% had problematic eHealth literacy, and the majority (59.00%) demonstrated sufficient eHealth literacy. There was a significant association between eHealth literacy and oral health outcomes. Individuals with problematic eHealth literacy had a higher likelihood of having a greater number of teeth (RR = 1.12, 95% CI: 1.05-1.20, p < 0.001) compared to those with inadequate eHealth literacy. Similarly, individuals with sufficient eHealth literacy showed a higher likelihood of having more teeth (RR = 1.14, 95% CI: 1.07-1.21, p < 0.001) compared to the inadequate eHealth literacy group controlling for age, gender, income, and education. Individuals with problematic eHealth literacy exhibited a tendency towards lower odds of irregular brushing (OR = 0.39, 95% CI: 0.15-1.02, p = 0.054), although this result was marginally significant. In contrast, individuals with sufficient eHealth literacy had significantly lower odds of irregular brushing frequency (OR = 0.24, 95% CI: 0.10-0.62, p = 0.003) compared to the inadequate eHealth literacy group.

CONCLUSION

The findings suggest a positive association between eHealth literacy and oral health outcomes. Improving eHealth literacy may have implications for promoting better oral health behaviors and outcomes.

Association between oral health knowledge, perceived oral health related quality of life, perceived oral health status and emergency department and/or urgent care visit: Results from the multi-site oral health literacy study

OBJECTIVES

To assess the link between oral health knowledge (OHK), self-perceived oral health, and emergency room (ER)/urgent care utilization for a dental problem.

METHODS

Data were analyzed from a convenience sample of 790 adult participants who presented to two US dental schools and completed an interviewer-administered survey. Key independent variables were OHK assessed with the Comprehensive Measure of Oral Health Knowledge (CMOHK) instrument, self-perceived oral health status and quality of life determined using the General Oral Health Assessment Index (GOHAI) scores. The dependent variable was ER and/or urgent care utilization for a dental problem. Select sociodemographic variables such as age and gender were adjusted for in logistic regression models using SAS.

RESULTS

15.7% of the participants had ever visited an ER and/or urgent care for a dental problem. CMOHK scores were not significantly associated with visits to the ER and/or urgent care. In adjusted analysis, participants with unfavorable GOHAI scores were about three times as likely to have had an ER and/or urgent care visit (OR = 2.60, 95% CI: 1.66-4.09). Similarly, participants who were unsatisfied with their oral health were about twice as likely to have had an ER and/or urgent care visit (OR = 1.91, 95% CI: 1.21-3.00) as compared to those satisfied with their oral health status.

CONCLUSION

Individuals unsatisfied with their oral health and those with unfavorable perceived oral health related quality of life could benefit from a greater awareness of dental service availability and extended hours including weekend hours at public dental clinics.

Oral health literacy and its associated factors among nurses: A cross-sectional study

AIMS AND OBJECTIVES

To investigate the oral health literacy (OHL) of nurses and explore the factors affecting their OHL.

BACKGROUND

OHL is important for improving the oral health outcomes. Nurses' OHL may affect the oral health of themselves, families, and patients. Few studies have examined the OHL and its related factors among nurses.

DESIGN

A cross-sectional design following the STROBE guideline.

METHODS

A total of 449 nurses were recruited from tertiary hospitals in the minority areas of southwest China. The participants completed an online questionnaire, which contained questions related to the OHL, sociodemographic factors, general health, oral health and related behaviours, oral health knowledge, attitudes, and oral health-related quality of life. OHL was measured using the validated Chinese version of the short-form Health Literacy of Dentistry (HeLD-14) scale. Descriptive statistics, the Mann-Whitney U test, Spearman's correlation, and multiple linear regression analysis were used to analyse the data.

RESULTS

The median HeLD-14 score (p25-p75) was 50.0 (44.0-54.0). The regression model for OHL was found to be significant. The factors that influenced OHL included oral health knowledge, oral health attitudes, self-reported oral health, annual household income, and dental flossing; these factors accounted for 13.9% of the variance in OHL.

CONCLUSIONS

The nurse' OHL has room for improvement. Nurses' OHL could be improved by enriching their oral health knowledge, promoting their positive oral health attitudes, increasing their household income, and helping them build correct oral health behaviours.

RELEVANCE TO CLINICAL PRACTICE

The findings of the study could be used to make a case for changing nursing curricula. Oral health knowledge curriculum or programmes targeted towards nurses should be developed to improve their OHL.

Defining the Connotations of Oral Health Literacy Using the Conceptual Composition Method

Due to advancements in research, the concept of oral health literacy (OHL) has become rich in connotations, with over 250 definitions present in the literature and government and organizational reports. The diversity of OHL definitions and connotations not only produces conflicting results but also limits the production of accurate OHL measurement and assessment tools while simultaneously hindering the construction of health literacy intervention policies. To clarify the connotations of OHL and establish a scientific basis for evaluation, we conducted a systematic review, searching and analyzing the literature related to the conceptual connotations of OHL. Additionally, we extracted basic, methodological, and OHL conceptual connotation information from the literature. With reference to the review framework, we classified the conceptual connotations of OHL into antecedents of OHL, the core of OHL, mediators, and outcomes of OHL. The comprehensive conceptual connotations of OHL were obtained through a systematic review and concept mapping based on the related literature. Our analysis revealed that the antecedents of OHL can be classified in two categories: personal factors and external factors. The core conceptual connotations of OHL include three core dimensions (with 16 subdimensions): (1) basic skills-literacy, reading comprehension, numeracy, hearing, oral expression, communication, and knowledge; (2) information-related abilities-information acquisition, information understanding, information communication, information evaluation, information utilization, and information decision-making; and (3) oral health maintenance abilities-interpersonal skills, self-regulation, and goal achievement. The mediator of these connotations is oral health behaviors, with oral health being the result of OHL. This study further clarifies the conceptual connotations of OHL, serving as a reference for future OHL-related studies.

Can Patients Read, Understand, and Act on Online Resources for Anterior Cruciate Ligament Surgery?

Background:

Patients undergoing elective procedures often utilize online educational materials to familiarize themselves with the surgical procedure and expected postoperative recovery. While the Internet is easily accessible and ubiquitous today, the ability of patients to read, understand, and act on these materials is unknown.

Purpose:

To evaluate online resources about anterior cruciate ligament (ACL) surgery utilizing measures of readability, understandability, and actionability.

Study Design:

Cross-sectional study; Level of evidence, 4.

Methods:

Using the term “ACL surgery,” 2 independent searches were performed utilizing a public search engine (Google.com). Patient education materials were identified from the top 50 results. Audiovisual materials, news articles, materials intended for advertising or medical professionals, and materials unrelated to ACL surgery were excluded. Readability was quantified using the Flesch Reading Ease, Flesch-Kincaid Grade Level, Simple Measure of Gobbledygook, Coleman-Liau Index, Automated Readability Index, and Gunning Fog Index. The Patient Education Materials Assessment Tool for Printable Materials (PEMAT-P) was utilized to assess the actionability and understandability of materials. For each online source, the relationship between its Google search rank (from first to last) and its readability, understandability, and actionability was calculated utilizing the Spearman rank correlation coefficient (ρ_S).

Results:

Overall, we identified 68 unique websites, of which 39 met inclusion criteria. The mean Flesch-Kincaid Grade Level was 10.08 ± 2.34, with no website scoring at or below the 6th-grade level. Mean understandability and actionability scores were 59.18 ± 10.86 (range, 33.64-79.17) and 34.41 ± 22.31 (range, 0.00-81.67), respectively. Only 5 (12.82%) and 1 (2.56%) resource scored above the 70% adequate PEMAT-P threshold mark for understandability and actionability, respectively. Readability (lowest P value = .103), understandability (ρ_S = –0.13; P = .441), and actionability (ρ_S = 0.28; P = .096) scores were not associated with Google rank.

Conclusion:

Patient education materials on ACL surgery scored poorly with respect to readability, understandability, and actionability. No online resource scored at the recommended reading level of the American Medical Association or National Institutes of Health. Only 5 resources scored above the proven threshold for understandability, and only 1 resource scored above it for actionability.

Definitions and measurement of health literacy in health and medicine research: a systematic review

OBJECTIVES

The way health literacy is understood (conceptualised) should be closely linked to how it is measured (operationalised). This study aimed to gain insights into how health literacy is defined and measured in current health literacy research and to examine the relationship between health literacy definitions and instruments.

DESIGN

Systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

DATA SOURCES

The MEDLINE, PsycINFO, ERIC and CINAHL databases were searched for articles published during two randomly selected months (March and October) in 2019.

ELIGIBILITY CRITERIA

We included articles with a quantitative design that measured health literacy, were peer-reviewed and original, were published in the English language and included a study population older than 16 years.

DATA EXTRACTION AND SYNTHESIS

Six researchers screened the articles for eligibility and extracted the data independently. All health literacy definitions and instruments were considered in relation to category 1 (describing basic reading and writing skills, disease-specific knowledge and practical skills) and category 2 (social health literacy competence and the ability to interpret and critically assess health information). The categories were inspired by Nutbeam's descriptions of the different health literacy levels.

RESULTS

120 articles were included in the review: 60 within public health and 60 within clinical health. The majority of the articles (n=77) used instruments from category 1. In total, 79 of the studies provided a health literacy definition; of these, 71 were in category 2 and 8 were in category 1. In almost half of the studies (n=38), health literacy was defined in a broad perspective (category 2) but measured with a more narrow focus (category 1).

CONCLUSION

Due to the high degree of inconsistency between health literacy definitions and instruments in current health literacy research, there is a risk of missing important information about health literacy considered be important to the initial understanding of the concept recognised in the studies.

Rural-Urban Differences in Dental Service Utilization and Dental Service Procedures Received Among US Adults: Results From the 2016 Medical Expenditure Panel Survey

PURPOSE

To assess rural-urban differences in dental service use and procedures and to explore the interaction effects of individual- and county-level factors on having dental service use and procedures.

METHODS

Data were from the 2016 Medical Expenditure Panel Survey (MEPS). We assessed rural-urban differences in 3 outcome variables: number of dental visits (1, 2, or 3+ visits), preventive care procedures (Yes/No), and treatment procedures (Yes/No). The study sample included 8,199 adults ≥ 18 years of age who reported at least 1 dental visit in the past year. Sampling weights embedded in MEPS were incorporated into all the analyses.

FINDINGS

A significant interaction between residential location and race/ethnicity (P = .030) suggested limited access to dental visits for minority groups, especially for blacks in the more rural areas. Adults from a more rural area were less likely to have received a preventive procedure (AOR = 0.55, 95% CI: 0.35-0.87) than those from an urban area. Adults of racial/ethnic minority groups, with lower SES, and without dental insurance were less likely to have received a preventive procedure (all P < .01) but were more likely to have received a treatment procedure (all P < .05).

CONCLUSIONS

The study showed rural adults were less likely to have received preventive dental procedures than their urban counterparts. Racial/ethnic minority groups living in a more rural area had even more limited access to dental services. Innovative service delivery models that integrate telehealth and community-based case management may contribute to addressing these gaps in rural communities.

Health Literacy Associations with Periodontal Disease among Slovak Adults

Periodontal disease is inflammation of the gums and without good oral hygiene, it can progress to periodontitis. Oral hygiene might be related to a patient’s health literacy (HL), defined as ability to gain access, understand, and use information to promote and maintain good health. The aim of our study is to examine the associations of HL with indicators of periodontal disease. A cross-sectional study on 1117 adults (36.2% males; mean age = 36.4, SD = 14.2) attending dental hygiene treatment was conducted. Data on demographics, socioeconomic status, and nine domains of HL (Health Literacy Questionnaire, HLQ) were collected by questionnaire, and Community Periodontal Index of Treatment Needs (CPITN) was established by the dental hygienist. Data were analysed using t-tests and logistic regression. Respondents with periodontal disease (N = 152) had statistically significantly lower levels of HL in seven out of nine HLQ domains compared to intact patients (N = 818) (t from 3.03 to 4.75, p < 0.01). Association of higher HL in seven domains with lower chance of diagnosed periodontal disease remain significant even after adjustment for age, gender and educational attainment (adjusted ORs 0.55–0.67, p < 0.05). Our findings confirm that an individual’s lower HL is significantly associated with higher chance of periodontal disease incidence, specifically among Slovak adults attending oral hygiene clinics. HL might be a promising factor in the improvement of oral health in this population, worthy of consideration in intervention and preventive activities.

Oral health literacy: A practical strategy towards better oral health status among adult population of Ghaziabad district

BACKGROUND AND AIMS

Despite tremendous considerable effort by health professionals to promote oral health to create beautiful smiles, gap between oral health knowledge and practice undoubtedly still remains. Thus the aim of this study was to assess the Oral health literacy level and its impact on socioeconomic and oral health status among adult population in Ghaziabad district.

METHODS

A total of 600 study subjects aged 18-64 years from all 4 blocks of Ghaziabad visiting various outreach programmes using a multistage random sampling technique were included in the study. A specially designed questionnaire assessed the demographic variables. Oral health literacy level (OHL) was assessed with help of a bilingually adapted Hindi OHL tool. Clinical examination was recorded using WHO (World Health Organization) Oral Health Assessment Form 2013.

RESULTS

The mean age of the study subjects was 43.9 ± 14.36 years. Majority 300 (50%) study subjects had inadequate oral health literacy level followed by Marginal oral health literacy level which was seen among 180 (30%) subjects and 120 (20%) subjects had adequate oral health literacy level. Oral health literacy level was slightly higher among females as compared to male subjects although the results were not statistically significant. A statistically significant difference was found between oral health literacy and oral health status as well as socioeconomic status. (P value ≤ 0.05).

CONCLUSION

A significant association between OHL and oral health status was found stating Oral health literacy as an efficient role in influencing oral health outcome of any individual.

Exploring the Maternal and Infant Oral Microbiomes: A Pilot Study

Setting the stage for good oral health early in life is critical to long-term oral and overall health. This exploratory study aimed to characterize and compare maternal and newborn oral microbiota among mother-infant pairs. Oral samples were collected from 34 pregnant African American women and their infants at 1 to 3 months of age. Extracted 16SrRNA genes were matched to the Human Oral Microbiome Database. Alpha and beta diversity differed significantly between overall maternal and infant microbiomes. Maternal or infant alpha diversity, however, was not differentiated by maternal gingival status. Several demographic and behavioral variables were associated with, but not predictive of, maternal oral microbiome alpha diversity. There was no association, however, among birth mode, feeding mode, and the infant oral microbiome. Megasphaera micronuciformis was the only periodontal pathogen detected among the infants. Notably, maternal gingival status was not associated with the presence/absence of most periodontal pathogens. This study provides an initial description of the maternal and infant oral microbiomes, laying the groundwork for future studies. The perinatal period presents an important opportunity where perinatal nurses and providers can provide oral assessment, education, and referral to quality dental care.
