Associations and discrepancies between global self-ratings of oral health and general health: a Bayesian approach

OBJECTIVE

To estimate the discrepancies between global ratings of oral health and general health and investigate the factors associated with self-rated oral health (SROH) and self-rated general health (SRGH).

METHODS

Data were collected from 502 participants aged 18 to 81 years. A structured questionnaire was used to obtain data regarding sociodemographic characteristics and self-reported conditions. Global self-ratings of oral health and general health were the main outcomes. Discrepancies between self-ratings of oral health and general health were stratified by independent variables. Bayesian ordinal logistic regression models were fitted to estimate the posterior distributions of parameters and 95% credible intervals (95% CrI).

RESULTS

The proportion of participants who rated their oral health worse than general health was 28.6% (95% CrI: 24.7-32.3). Negative discrepancies between SROH and SRGH were associated with being men, reporting gingivitis, and lower income. Sex (95% CrI: 1.12-2.25) impacted only on SRGH. Income (SROH - 95% CrI: 1.52-6.40; SRGH - 95% CrI: 1.08-4.56), tertiary education (SROH - 95% CrI: 1.13-2.53; SRGH - 95% CrI: 1.01-2.32), self-reported missing teeth (SROH - 95% CrI: 1.57-3.46; SRGH - 95% CrI: 2.21-4.92), self-reported gingivitis (SROH - 95% CrI: 1.10-2.40; SRGH - 95% CrI: 1.71-3.82), and self-reported chronic health problem (SROH - 95% CrI: 1.38-3.08; SRGH - 95% CrI: 1.61-3.59) impacted on both outcomes.

CONCLUSIONS

Substantial discrepancies between self-rated oral health and self-rated general health were found and were associated with being male, reporting gingivitis, and having lower income.

Health literacy and self-efficacy associations with non-adherence to dental treatment among young adults

The aim of this study was to investigate associations of health literacy (HL), general self-efficacy (GSE), and sociodemographic variables with non-adherence to dental treatment among Brazilian young adults. This is a cross-sectional study based on a cohort study of 248 young adults aged 19 to 25 years followed up in an earlier study. The participants completed the perceived general self-efficacy scale (GSE), a questionnaire on socioeconomic and demographic variables and were examined for oral conditions. HL was measured using the Brazilian version of the health literacy questionnaire (HLQ-Br), which provides nine individual scores based on an average of the items within each of the nine scales. Dental treatment adherence was evaluated as the decision of young adults to seek a dentist to finish the recommended restorative treatment for dental caries. The effects of HL domains on the adherence to dental treatment were analyzed by logistic regression and the effect was adjusted for sex, age, family income, paternal and maternal education, type of housing, and self-efficacy. The results of the adjusted analysis showed associations among young adults who did not adhere to dental treatment with lower self-efficacy levels, living in non-owner-occupied homes, and lower HL levels in almost all of the HL domains (p < 0.05). Only the HLQ6 domain "Ability to actively engage with healthcare providers" was not associated with the outcome (p>0.05). Adherence to dental treatment in primary care among young adults was associated with their general self-efficacy levels, socioeconomic characteristics, and individual's lower HL aspects.

[Reasons given by patients for inappropriate use of emergency medical services]

OBJECTIVE

The aim of this study was investígate the reasons for the demand for these services by users rated on two non-urgent emergency care units of a medium-sized municipality of São Paulo.

METHODOLOGY

Qualitative data were collected through semi-structured interviews with 756 individuals who sought the services of emergency care units and, of these, 417 (55%) users were classified as non-urgent risk and were eligible for the study.

RESULTS

It was observed six major categories of motives among that seeking care in emergency care units: lack of infrastructure of the nearest health unit; perception of pain and symptoms of emergency; home/work proximity; takes care of scheduling and primary health care; quality of care in the emergency care units; habit of attending services. These categories were grouped into four themes concerning: a) perception of urgency; b) convenience; c) difficulty of access and d) quality of service.

CONCLUSION

It was concluded from these findings the need to strengthen primary care system in order to ensure facilitated access for users and better resolution of cases that can be seen treated in this level, in conjunction with the entire network of health care.

[Perceived barriers and coping strategies developed by patients with type 2 diabetes mellitus to join to walking]

OBJECTIVE

To investigate the perceived barriers and coping strategies for the practice of walking identified among patients with diabetes mellitus (DM) in the scope of the Unified Health System (SUS).

METHODOLOGY

A sample of 83 individuals with DM, SUS users, was asked to reflect on the obstacles that prevented them from walking, as well as to formulate coping plans to overcome them. The obstacles raised and plans developed were categorized for similarity and subjected to frequency analysis.

RESULTS

The main obstacle reported was the feeling of "dismay" (36.1%). The most frequent coping plan to overcome the barriers found was 'social support from family members', 'neighbors' and 'friends'.

CONCLUSION

The results made it possible to know the difficulties and potential of the subjects related to self-care for DM regarding the practice of walking, knowledge that can help the multidisciplinary teams of the SUS.

Factors associated with the absence of Brazilians in specialized dental centers

Aim

To identify the individual and contextual factors associated with the absence of Brazilians at a scheduled appointment in Dental Specialties Centers (DSC).

Methods

This cross-sectional design uses the National Program for Improving Access and Quality of Dental Specialties Centers database, 2018. The outcome was the users' lack of at least one of the scheduled appointments. Contextual and individual independent variables were used, considering Andersen's behavioural model. The analyses were performed with the R Core Team and SAS (Studio 3.8, Institute Inc, North Carolina, U.S, 2019) programs.

Results

Of the 10,391 patients interviewed, 27.7% missed at least one of the consultations. In the adjusted multivariate model, the interpretation based on the effect size and 95% CI showed that the behaviour individual predisposing factors such as age ≤ 42 years (OR = 1.10; 95%CI:1.01–1.21), individual need factors such as participation in the “Bolsa Família” program (OR = 1,14; 95%CI:1.02–1.27), not being covered by the Family Health Strategy (OR = 1.15; 95% CI:1.02–1.30), and users of periodontics services (OR = 1.22;95%CI:1.05–1.40) were associated with absences. The behavioural factor associated with the outcome was that the DSC facilities were not in good condition (OR = 1.18; 95%CI:1.03–1.34). DSC located in the capital (OR = 1.12; 95% CI: 0.92–1.48) were 12% more likely to have dental absences than those in the interior region.

Conclusion

There are individual and contextual barriers associated with patients not attending specialised public dental consultations. DSC should offer adequate hours to patients, especially young adults and vulnerable people.

Psychometric properties of the Brazilian version of the European Health Literacy Survey Questionnaire short form

The aim of this study was to analyze the psychometric properties of the Portuguese Brazilian version of the instrument for measuring health literacy European Health Literacy Survey Questionnaire short form (HLS-EU-Q16). The study sample consisted of 783 Brazilian adults with a mean age of 38.6 years. The data were analyzed through an extensive and robust process of testing the properties with the combination of exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and item response theory (IRT) techniques, aiming to search for strong validation evidence in the internal structure and stability step for other sub-samples. The instrument's reliability was tested using Cronbach's alpha and McDonald's Omega. The analyses indicated the existence of only one dimension and good reliability values. The model tested with cross-validation indicated satisfactory, adequate, consistent and stable levels for EFA, IRT via item discrimination and CFA, both for primary indicators as factor loadings, communalities, item discrimination as well as for the model adequacy indicators. It is concluded that the Brazilian Portuguese version of the HLS-EU-Q16 proved to be a one-dimensional, consistent, accurate and stable model for measuring health literacy in Brazilian adults.

A psychometric network perspective to oral health literacy: Examining the replicability of network properties across the general community and older adults from Brazil

Objectives

To evaluate the replicability of oral health literacy (OHL) network models across the general community and a sample of older adults from Brazil.

Methods

Data were obtained from two oral health surveys conducted with a total of 1138 participants. OHL was measured using the short form Health Literacy in Dentistry scale (HeLD‐14). A regularized partial correlation network was estimated for each sample. Dimensionality and structural stability were examined via exploratory graph analysis. Network properties compared included global strength, edge weights, and centrality estimates. Model replicability was examined fitting the general community model to the older participants' data.

Results

Six dimensions with the exact same item composition were detected in both network models. Only the Receptivity domain in the older adults sample yielded low structural stability. Strong correlations were observed between edge weights (τ: 0.68; 95% CI: 0.62–0.74) and between node strength estimates (τ: 0.63; 95% CI: 0.36–0.89). No statistically significant differences were found for global strength. The fit of the older adults sample to the HeLD‐14 network structure of the general community sample was satisfactory.

Conclusion

Network models OHL replicated across the general community and a sample of older adults. The psychometric network approach is a useful tool to evaluate the measurement equivalence of OHL instruments across populations.

Coping strategies of caregivers in performing oral hygiene care in adults with special needs: A qualitative study

INTRODUCTION

Basic and daily oral hygiene care is essential for maintaining oral health in adults with special needs. The caregivers act in this process and need to be understood about the difficulties and the resources they use to deal with this demand. The aim of this qualitative study was to understand the difficulties and strategies of caregivers regarding oral hygiene for adults with special health care needs (SHCN) METHODS: Twenty-one caregivers of adults with SHCN participated in an interview in which the following questions were asked: What are the greatest difficulties in performing oral hygiene for the adult with SHCN you take care? and "How do you overcome these difficulties?" The interviews were recorded and the qualitative data were analyzed using the Discourse of the Collective Subject technique RESULTS: All respondents were female with a mean age of 58.5 years (± 10.8) and the adults with SHCN presented mean age of 30 years (± 18). The greatest difficulty pointed out by caregivers regarding oral hygiene for adults with SHCN was their non-cooperation to do such activity. Regarding coping strategies, caregivers pointed out several strategies to perform oral hygiene in adults with SHCN, such as supervising their brushing, seek for a qualified dentist to assist with this task, performing oral hygiene during the bath, performing physical restraint, among others CONCLUSION: The caregivers' perspectives indicate feelings of failure, discomfort, but also the use of creative resources to deal with the task. The results bring up themes that refer to anxieties and are related to technical and dental issues, that could be explored and need to be recognized by the reference oral healthcare team, whose responsibility it is also to work for the empowerment of caregivers.

Produção científica em saúde da população LGBTQIA+: uma análise crítica do conteúdo da literatura

Resumo Esta pesquisa traz em seu escopo a análise do potencial estigmatizador do conteúdo de estudos direcionados à população LGBTQIA+ indexados na plataforma PubMed. Por meio de uma ampla e sistemática pesquisa bibliográfica foram identificados e incluídos, respectivamente, 821 e 334 (40,68%) artigos, dos quais foram extraídos 1838 descritores. Da análise dos dados coletados foram identificados as maiores prevalências dos descritores “men having sex with man” (192 repetições) e “HIV” (98 repetições). Sendo assim, o percurso analítico das informações levantadas refletiu que a população LGBTQIA+ é essencialmente designada como “homens que fazem sexo com outros homens e soropositivos”. Este estudo traz, portanto, a presença de características estigmatizantes nos estudos direcionados à população LGBTQIA+. Contudo, cabe destacar que o resultado encontrado é subsídio para o fortalecimento de uma perspectiva crítica de um fazer científico mais humanizado e direcionado às especificidades e necessidades da população LGBTQIA+.

Scientific production on LGBTQIA+ health: a critical analysis of the literature

Abstract This study analyzes the stigmatizing potential of studies on the LGBTQIA+ population indexed on the PubMED database. By a broad and systematic bibliographic search, 821 publications were found and 334 (40.68%) were included in this study. From these, 1838 keywords were extracted. Data analysis showed that the keywords “men who have sex with man” (192 repetitions) and “HIV” (98 repetitions) had the highest prevalence. Thus, according to the analysis, the LGBTQIA+ population is essentially described as “men who have sex with other men” and “HIV positive.” This study unveils the presence of stigmatizing characteristics in studies on the LGBTQIA+ population. However, such findings can help strengthen the critical perspective of a more humanized scientific practice, actually concerned with the specificities and needs of the LGBTQIA+ population.

Effect of educational strategy combined with ART on oral health-related quality of life: a controlled clinical trial

This study aimed to assess whether complementing atraumatic restorative treatment (ART) with oral health educational strategies (OHES) improves the perception of oral health-related quality of life (OHRQoL) and clinical oral outcomes. A controlled clinical trial included 93 six- to eight-year-old students from five public schools of Piracicaba, Saltinho, and Charqueada municipalities (State of São Paulo, Brazil) divided into 3 groups (31 children each) which received: OHES (caries-free), ART (dental caries), and ART plus OHES (dental caries). OHRQoL (CPQ8-10-ISF:16), dental caries, biofilm control, and gingivitis were assessed before and 1 month after interventions by one calibrated examiner. OHES consisted of an educational interactive activity performed once a week for four weeks. Data were analyzed using mixed model ANOVA, Chi-square, and Sign tests. After 1 month of follow-up, improvement in gingivitis status, OHRQoL total score, and Functional Limitations, Emotional Well-Being and Social Well-Being domains scores were found in all groups (p < 0.05). The improvement in biofilm control was observed only in the OHES group (p < 0.001; power = 0.98), while a decrease in Oral Symptoms scores was observed only in ART+OHES group (p <0.001; power = 0.99) and a significant change in the perception of oral health was observed in the two groups that received ART (p < 0.05). In conclusion, improvement in overall OHRQoL and oral status was observed in all children, although the effect of including health educational strategies in the treatment plan was determinant for the perception of an improved oral health after restorative treatment.

Repercussions of the COVID-19 epidemic on Brazilian National Health System urgent dental care in Piracicaba, Brazil, 2020

OBJECTIVE

To evaluate the repercussions of the COVID-19 pandemic on procedures performed by a public urgent dental care service (PUDS).

METHODS

This was a cross-sectional study, using data from the PUDS in Piracicaba, SP, Brazil, prior to the pandemic (February-March 2020) and during the pandemic (March-April 2020). Differences in the care profile between the pre-COVID-19 period and the COVID-19 period, according to sex, age and dental procedures were analyzed using Pearson's Chi-square test. Effect size was also measured using Cramer's V.

RESULTS

There was a 51% reduction in the number of visits between the pre-COVID-19 period (n=824) and the COVID-19 period (n=404). The percentage of extractions reduced from 14.7% to 8.9%, while the percentage of temporary cavity fillings increased from 22.9% to 33.2%, between the two periods.

CONCLUSION

The COVID-19 pandemic had repercussions on the amount and pattern of procedures performed at the city's urgent dental care service.

Evaluating the psychometric properties of the eHealth Literacy Scale in Brazilian adults

OBJECTIVE

To translate and adapt the eHealth Literacy Scale for the cultural reality of Brazil and to evaluate the psychometric properties of its Brazilian Portuguese version.

METHODS

The instrument was translated and adapted to Brazilian Portuguese and applied to a sample of 502 individuals from 18 to 80 years old who lived in the surrounding areas of six Family Health Units of a city in the countryside of the state of São Paulo, Brazil. The data was evaluated using exploratory and confirmatory factor analysis, item response theory, and instrument reliability measures (Cronbach's alpha and McDonald's omega).

RESULTS

The eHealth Literacy Scale - Brazilian version (eHEALS-Br) presented an excellent internal consistency (α = 0.95 e ω = 0.95), with only one dimension and an explained variation of 81.79%.

CONCLUSIONS

The Brazilian version of the instrument showed excellent psychometric properties to measure the levels of digital health literacy in adults from the country.

Psychometric properties of the adapted instrument European Health Literacy Survey Questionnaire short-short form

OBJECTIVE

to investigate the psychometric properties of the Brazilian Portuguese version of the health literacy questionnaire European Health Literacy Survey Questionnaire short-short form (HLS-EU-Q6) in Brazilian adults.

METHOD

the instrument was translated and pre-tested in a sample of 50 individuals. Subsequently, it was applied to a sample of 783 adult individuals. The data went through an appropriate process of testing the properties, with the combination of techniques of Exploratory Factor Analysis, Confirmatory Factor Analysis and Item Response Theory. For the assessment of reliability, the Cronbach's alpha and McDonald's Omega indicators were used. Cross-validation with full data analysis was applied.

RESULTS

the majority of the participants was female (68.1%), with a mean age of 38.6 (sd=14.5) years old and 33.5% studied up to elementary school. The results indicated a unidimensional model with an explained variance of 71.23%, adequate factor load levels, commonality and item discrimination, as well as stability and replicability of the instrument to other populations.

CONCLUSION

the Brazilian version of HLS-EU-Q6 indicated that the instrument is suitable for indiscriminate application in the population to which it is intended to assess health literacy levels.

Oral health-related quality of life among Brazilian adults with mental disorders

The aim of this study was to investigate associations of sociodemographic, lifestyle, medical conditions, and caries experience with oral health-related quality of life (OHRQoL) in a large sample of adults with mental disorders. A sample of 753 adults diagnosed with schizophrenia or depression, who were users of 10 public mental health outpatient clinics located in the city of São Paulo, Brazil, participated in the study. Participants provided data on sociodemographic characteristics, psychiatric diagnosis, medication use, and health behaviors. Oral examinations to evaluate dental caries (using the decayed, missing, and filled teeth ([DMFT] index) and dental plaque (using the Silness-Löe plaque index) were conducted. Oral health-related quality of life was evaluated using the 14-item Oral Health Impact Profile (OHIP-14) questionnaire. Log-Poisson regression was used to evaluate associations between the outcome and independent variables. The prevalence of one or more OHIP-14 impacts occurring fairly often/often was 72.3%. Physical pain was the OHIP domain with the highest prevalence, followed by psychological discomfort. Multivariable analysis showed that higher prevalence of the reponses 'fairly often/often' in the OHIP-14 was associated with being female, aged 35 to 54 years, having a low family income, a diagnosis of depression, a smoking habit, and fewer than 20 teeth. Adults with mental disorders had a high prevalence of impacts on their OHRQoL, which were associated with caries experience, sociodemographic characteristics, type of psychiatric diagnosis, and behavioral risk indicators.

Factors associated with poor oral health-related quality of life among non-institutionalized Brazilian older adults: Oral health and quality of life in older adults

AIMS

To investigate the factors associated with poor oral health-related quality of life (OHRQoL) in a sample of Brazilian older adults.

METHODS AND RESULTS

A cross-sectional study was conducted with 535 non-institutionalized elders aged 60 years or older from Piracicaba, São Paulo, Brazil. OHRQoL was measured using the Geriatric Oral Health Assessment Index (GOHAI). Data on sociodemographic characteristics, self-perceived general health status, and health-related behaviors were obtained through a structured questionnaire. Data on chronic diseases were obtained from health records. Associations between exploratory factors and low OHRQoL (% GOHAI score <30) were evaluated using multivariate Poisson regression models to estimate adjusted prevalence ratios (PRs) and confidence intervals. The mean OHRQoL score was 30 (± 4.4). In bivariate analysis, being not married, smoking, and self-rated "fair/poor" general health status were associated with lower OHRQoL. In the adjusted model, self-rated "fair/poor" general health (PR: 1.25; 95% CI: 1.05-1.48), presence of chronic diseases (PR: 1.88; 95% CI: 1.37-2.58), smoking (PR: 1.25; 95% CI: 1.02-1.53), and reason for last dental appointment (PR: 1.34; 95% CI: 1.13-1.59) were associated with poor OHRQoL.

CONCLUSION

Non-institutionalized older adults with a history of chronic diseases, who smoke, have a negative perception of their general health, and had the last dental appointment motivated by pain present significantly higher prevalence rates of poor OHRQoL.

Cross-cultural adaptation and validation of the Self-efficacy Scale to Brush Teeth at Night

This study aims to perform cross-cultural adaptation and validation of the "Self-efficacy scale to brush teeth at night" with a Brazilian adult population. Translation and cross-cultural adaptation to the Brazilian-Portuguese language were done according to the stages recommended in the literature. Construct validity was carried out by mean of exploratory and confirmatory factorial analysis in a sample of 198 adult subjects. The reliability of the instrument was measured by Alpha and Omega indices. The model was observed to have been established as one-dimensional for all indicators, with explained variance of 85.7%; factorial loads between 0.85 and 0.91; and with communalities between 0.72 and 0.83. The goodness of fit of the model shown by the confirmatory model were between 0.98 and 0.99; with factorial loads between 0.85 and 0.93, and regression values between 0.69 and 0.84, all above the minimum indices established for instrument quality. For reliability, the Alpha and Omega values had identical indices of 0.95 showing high levels of reliability of the model. The G-H index replicability was 0.96, indicating the stability of solution in other contexts and samples. We concluded that all indicators represented excellent evidence of scale validity to measure self-efficacy to brush teeth at night.

Effect of implementation intention on walking in people with diabetes: an experimental approach

OBJECTIVE

To evaluate the effect of implementation intentions as an intervention strategy to promote walking in adults with type 2 diabetes mellitus (T2DM).

METHODS

We conducted a controlled and randomized trial, with 12 months of follow-up, involving 65 people with T2DM recruited from primary health care units and allocated them in the control group (CG, n = 32) and intervention group (IG, n = 33). The IG received the implementation intention strategy to promote walking and the CG remained in follow-up for conventional treatment in primary health care. The researchers were blinded by anthropometric measurements and the filling of the instruments.

RESULTS

After twelve months of follow up, the IG presented a statistically significant increase in the leisure time physical activity when compared with the CG (p = 0.0413) and showed a significant decrease in waist circumference (p = 0.0061). No significant difference was observed regarding body mass index and glycated hemoglobin among groups.

CONCLUSIONS

Implementation intention was effective in promoting walking and improving clinical indicators in adults with T2DM.

Self-perception of oral health in the elderly associated with health literacy and related factors

The aim of this study was to evaluate the self-perception of oral health in the elderly and to verify its association with oral health literacy and sociodemographic factors, through a cross-sectional study. Data collection took place in a probabilistic sample consisting of 535 elderly people over 60 years of age, who did not have cognitive problems, and were residents of the areas covered by six Family Health Units of the public health service, as well as users of a Center for Dental Specialties and dental clinics at the Faculty of Dentistry of Piracicaba (FOP), all located in the city of Piracicaba, Sao Paulo. A questionnaire with sociodemographic and health issues was applied, as well as the Health Literacy in Dentistry (HeLD-14) instrument for the assessment of oral health literacy. Poisson regression was used to estimate the associations between self-perceived oral health and literacy in oral health, as well as sociodemographic and general health characteristics. The data were analyzed using the SAS statistical software. The final regression model demonstrated that the elderly who were more likely to report poor oral health self-perception were associated with a low level of oral health literacy, were of the “non-white” ethnic group, had chronic illnesses and had sought the dentist for curative reasons in the last year. It was concluded that the self-perception of oral health in the elderly is influenced by variables that go beyond the dental sector, a fact that demands multiprofessional and intersectoral actions for their care. This fact highlights the importance of integrating aspects of health literacy in health and sociodemographic factors into the process of assessing oral health in the elderly, expanding the perspective of public health assessment for actions focused only on normative needs.

Key messages

We show the importance of assessing the oral health of the elderly in association with health literacy, expanding the perspective of public health assessment to actions beyond the normative needs. Despite the importance of the topic, there is still a scarcity of studies on health literacy and its impact on oral health behaviors and outcomes, impacting public health.

The effect of caries increment on oral health-related quality of life among adolescents in Brazil: a 3-year longitudinal study

This study aimed to assess the effect of caries increment on Oral Health-related Quality of Life (OHRQoL) of Brazilian adolescents and to evaluate the responsiveness of the Child Perceptions Questionnaire (CPQ11-14) in this group. A population-based sample of 515 Brazilian 12-year-olds from a large city located in the southeast of Brazil was evaluated according to a random multistage sampling design at baseline and 291 at three years follow-up, using the DMFT index and the CPQ11-14 instrument. To evaluate the responsiveness to change, the measures of effect size and longitudinal construct validity were used. It was verified that OHRQoL among adolescents with DMFT increment across the three years worsened significantly (p<0.05) in relation to their counterparts. The effect size varied from small to moderate. The longitudinal construct validity of CPQ11-14 was satisfactory. Caries increment impacted on OHRQoL of adolescents in Brazil. The CPQ11-14 instrument demonstrated acceptable responsiveness properties.

Self-perceived dental treatment need among adolescents: A hierarchical analysis

OBJECTIVES

The aim of the present study was to analyse the factors associated with self-perceived need for dental treatment among adolescents.

METHODS

A representative sample in the state of São Paulo, Brazil, comprising 5558 adolescents, was evaluated in 2015. The adolescents were selected by probabilistic sampling by conglomerates in two stages. The outcome evaluated was self-perceived treatment need measured via a validated questionnaire. Independent variables included sociodemographic factors, type, frequency and reason for last dental visit, and examination of oral conditions. Statistical analysis was based on the multiple hierarchical logistic regression model.

RESULTS

Of the total sample, 3340 (62.6%) adolescents reported needing dental treatment. After fitting the model, the self-perceived need for treatment was associated with adolescents with family income of up to $1,500 BRL (OR 1.39; [95% CI = 1.20-1.60]; P < .001), who sought dental services solely for curative treatment (OR 1.58; [95% CI = 1.46-1.72]; P < .001), reported toothaches in the previous six months (OR 2.88; [95% CI = 2.53-3.28]; P < .001), were dissatisfied with the appearance of their teeth and mouth (OR 5.94; [95% CI = 5.03-7.01]; P < .001), had caries in the posterior teeth only (OR 3.04; [95% CI = 2.77-3.33]; P < .001) or had caries in the anterior teeth (OR 4.75; [95% CI = 4.05-5.56]; P < .001).

CONCLUSIONS

The self-perceived need for dental treatment among Brazilian adolescents was associated with normative and subjective needs, and sociodemographic context factors. This finding provides important evidence for collective health planning.

Association between social conditions and oral health in school failure

OBJECTIVE

To evaluate the association of school failure among Brazilian adolescents with social conditions and aspects of oral health through hierarchical analysis.

METHODS

A state-wide survey of 5,558 adolescents from the state of São Paulo, Brazil, inquired about the sociodemographic and social capital of participants by using a structured questionnaire. Trained and calibrated professionals performed intraoral examinations and interviews in the households. Questions about the access to dentist, reason for and frequency of using dental services, toothache episodes and impact of oral conditions on daily activities (OIDP) were applied. Oral examinations evaluated caries experience, tooth losses, periodontal problems, presence of open bite, and maxillary and mandibular overjet. School failure was estimated according to the teenagers' years of schooling. The independent variables were grouped into three blocks: sociodemographic and economic characteristics, social capital and oral health aspects. The multiple hierarchical logistic regression model was used to identify the factors associated with school failure.

RESULTS

Of the total sample, information about schooling of 5,162 adolescents was obtained, of whom 29.6% presented school failure. We found that adolescents over the age of 16 years who did not declare themselves as white, female, with feelings of insecurity, unhappiness, with toothache, caries, tooth losses, affected by dentofacial and/or periodontal changes, were more likely to fail at school.

CONCLUSION

Oral disorders and social factors were associated with school failure in adolescents. A successful school trajectory was a strong determinant of health, therefore actions between the educational and health sectors must be developed for adolescents, especially those with this profile.

Validation of the Health Literacy in Dentistry scale in Brazilian adults

OBJECTIVES

To perform cross-cultural adaptation and validation of the Health Literacy Dental scale (HeLD) in Brazilian adults.

METHODS

The HeLD instrument was translated and cross-culturally adapted to the Brazilian Portuguese language to create longer (HeLD-29) and shorter (HeLD-14) versions. The reliability and validity of these versions were assessed in a sample of 603 adults living near six primary care units in the city of Piracicaba, São Paulo, Brazil.

RESULTS

Both versions of HeLD demonstrated high internal reliability, acceptable convergent validity and discriminant validity. However, the confirmatory factor analysis showed that only HeLD-14 demonstrated satisfactory goodness of fit. There were associations between HeLD-14 scores and social demographic characteristics, general and oral health and oral health-related behaviours. Higher scores were observed for the total HeLD-14 and/or individual components of HeLD-14 among women, ethnic white subjects, those with high educational attainment, those with higher income, those reporting toothbrushing twice or more daily, regular dental attenders, those who usually attended for dental care for a check-up, those with excellent or very good self-ratings of general health, those with excellent or very good self-ratings of oral health, and those without tooth extraction and oral health impact.

CONCLUSION

The Brazilian version of HeLD-14 was demonstrated to be a reliable and valid instrument for measuring broad aspects of oral health literacy in the adult Brazilian population.

Influence of oral health literacy on dissatisfaction with oral health among older people

OBJECTIVE

To investigate the influence of oral health literacy (OHL) and associated factors on dissatisfaction with oral health (DOH) among older people.

BACKGROUND

Oral health literacy is a recent field of research that has been considered an important mediator between socioeconomic variables and oral health outcomes. However, there are few studies with older people.

MATERIALS AND METHODS

A cross-sectional study was conducted with 535 non-institutionalised older people aged 60-100 years from Brazil. Individuals completed a questionnaire on general health, sociodemographic information and usual reason for dental visit. OHL was assessed using the Health Literacy in Dentistry questionnaire (HeLD-14), validated in Brazil. DOH was the outcome of interest. Poisson regression with robust standard errors was applied as a statistical model to estimate bivariate and multivariable relationships of DOH with OHL after adjusting for sex, age, social characteristics and general health using the P-value of ≤ .05.

RESULTS

The overall prevalence of DOH was 21.1%. Multivariable regression analysis showed that older people with low OHL (HeLD-14 score ≤35) had 1.28 times the odds of having DOH than those with high OHL (HeLD14 score >46), after adjusting for sociodemographic, economic and health outcomes.

CONCLUSIONS

Dissatisfaction with oral health in older people is a complex issue associated with OHL, social and behavioural factors. Health services should give greater attention to developing health literacy competences in older adults in order to empower them to achieve optimal oral health.

Evaluation of the psychometric properties of the Brazilian version of the Oral Health Literacy Assessment in Spanish and development of a shortened form of the instrument

OBJECTIVE

The objective of this study was to investigate the psychometric properties of the Oral Health Literacy Assessment in Spanish (OHLA-S) for the Brazilian-Portuguese language using robust analysis and with the results disclose possibilities to develop a shorter and more valid instrument.

METHODS

OHLA-S is an oral health literacy instrument comprising a word recognition section and a comprehension section. It consists of 24 dental words. It was translated into the Brazilian-Portuguese language (OHLA-B) and its psychometric properties were evaluated in a random sample of 250 adults aged 20-59 years. To assess the dimensionality and factor structure were tested by means of Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). Reliability was assessed using two indicators: Cronbach's alpha and McDonald's Omega.

RESULTS

EFA and CFA demonstrated that the OHLA-B with 24 items did not present an adequate adjustment of the model, compromising its validity. In addition, reliability values at 0.50 for Cronbach's alpha and 0.67 for McDonald's omega were below the minimum acceptable rate of 0.70. As no support was found for the original structure, we decided to proceed with the withdrawal of individual items and successive reanalysis of the model until the indicators were adjusted in a shorter instrument. A new structure with 15 items produced an instrument with two dimensions and a better goodness of fit than the original instrument. The Alpha and Omega reliability index values increased to 0.83 and 0.80, respectively, and all scores were better in the OLHA-B with 15 items than in the instrument with 24 items.

CONCLUSION

OLHA-B with the original structure composed by 24 items did not show acceptable construct validity. The shorter version with 15 items showed more promising results for assessing oral health literacy levels in the Brazilian population.

Impact of implementation intentions on physical activity practice in adults: A systematic review and meta-analysis of randomized clinical trials

OBJECTIVE

The aim of this study was to verify the efficacy of using theory-based strategies on implementation intentions in promoting physical activity (PA) among adults.

METHODS

This review was conducted in accordance with the PRISMA recommendations. The search was carried out in seven electronic databases (LILACS, PubMed, SciELO, Cochrane, Web of Science) and two searches of the "grey literature" were performed (Openthesis and OpenGrey). Randomized clinical trials (RCT), published up to September 2016, were considered eligible for this study. Two reviewers independently and systematically evaluated the eligibility criteria, and performed data extraction. A meta-analysis was performed for the purpose of comparing the effect between the intervention and control groups. The effect sizes were grouped in two subgroups with the purpose of more accurately verifying the effect caused by reinforcing the implementation intentions strategy, and using the inverse variance statistical method with random effects models to estimate the main effect of the implementation intention strategy on the PA behavior. Heterogeneity among the studies was evaluated by using I-square statistics, and the Jadad scale to evaluate the quality of included papers.

RESULTS

The search resulted in 12,147 records, of which 13 RCTs were considered eligible for this review. Sample age ranged from 18 to 76 years, and participants had conditions such as medullary lesion, coronary disease, obesity, diabetes mellitus, sedentarism or occupational stress. When the summary of the effect was analyzed in the meta-analysis, the result found in the subgroup with reinforcement of the implementation intentions strategy was 0.25 (IC 95% = 0.05-0.45) in favor of the intervention group. This demonstrated that application of the implementation intentions strategy was capable of increasing PA practice in the participants of these studies, in comparison with others that did not use this reinforcement.

CONCLUSION

The findings of this review indicated that application of the theory of implementation intentions promoted PA behavior among the adults who received reinforcement of this strategy. The systematic review protocol was registered in the PROSPERO database under the number CRD42018090482.

Irregularidades sanitárias na promoção comercial em rótulos de produtos para lactentes e os riscos para a saúde

RESUMO Regulamentações sanitárias para crianças e lactentes buscam controlar estratégias mercadológicas que estimulam o consumo de certos produtos. Na investigação realizada em pontos de venda, verificou-se heterogeneidade na frequência de falhas na rotulagem de bicos, chupetas e mamadeiras em várias marcas. Deficiências nas informações sobre o controle de fabricação e os aspectos de proteção ao aleitamento natural indicam uma conduta intencional das marcas líderes para a manutenção dessa situação, que pode ser agravada pela falta de monitoramento periódico da rotulagem e promoção comercial pela vigilância sanitária, implicando risco de desmame precoce e outros problemas de saúde durante a primeira infância.

The Impact of Molar-Incisor Hypomineralisation on Dental Caries in Permanent First Molars: A Prospective Cohort Study

PURPOSE

To compare 2-year cumulative survival rates in first permanent molars (FPM) with and without MIH and to investigate risk factors associated with caries incidence.

MATERIALS AND METHODS

A total of 142 children aged 5 to 6 years were recruited from all public schools in Botelhos, Minas Gerais, Brazil and 536 FPM were examined. A questionnaire was designed to collect sociodemographic background and behavioural information about children and their parents. Caries in FPM was recorded per surface in accordance with WHO methodology at baseline and once every 6 months over a period of two years. The survival analysis was conducted using the Weibull regression model with cure fraction.

RESULTS

MIH was present in 16.19% of children. The 2-year cumulative survival rates for FPM with and without MIH showed statistically significant differences, and visible plaque on anterior teeth had an effect on the survival rates.

CONCLUSION

Children with MIH and visible plaque on anterior teeth at baseline had a high risk for developing new caries lesions in their FPM over the course of two years. These variables should be considered in caries risk assessment in paediatric dental care.

Impact of a dental care program on the quality of life of children with and without caries

The aim of the present study was to evaluate the long-term effects of the caries treatment provided by a dental care program on changes in schoolchildren's OHRQoL. A one-year follow-up was conducted with a sample of 372 children aged 8 to 10 years which were clinically examined and divided into two matched groups according to their caries experience: dental treatment group (DTG) and group without caries (GWC). Both groups were assessed three times (at baseline, at 4 weeks, and at 1 year) using the Child Perceptions Questionnaire (CPQ8-10). The normality test was performed for the statistical analyses; the Friedman test was used for the dependent variables (longitudinal assessment repeated three times for the same group); and the Mann-Whitney test was used for the independent variables (test and control groups in each time period). There was improvement in all domains and in overall CPQ8-10 (p < 0.0001) in the DTG over time, but no significant changes (p > 0.05) were observed at baseline for overall CPQ8-10 and for the emotional well-being domain in the GWC. The comparison between groups demonstrated that OHRQoL was persistently better for the GWC (p < 0.05) over time. In conclusion, dental caries treatment has a long-term positive impact on schoolchildren's OHRQoL, highlighting the importance of health policies that promote access to dental care for this population.

Variables associated with the performance of Centers for Dental Specialties in Brazil

The aim of this study was to evaluate the performance of the Centers for Dental Specialties (CDS) in the country and associations with sociodemographic indicators of the municipalities, structural variables of services and primary health care organization in the years 2004-2009. The study used secondary data from procedures performed in the CDS to the specialties of periodontics, endodontics, surgery and primary care. Bivariate analysis by χ2 test was used to test the association between the dependent variable (performance of the CDS) with the independents. Then, Poisson regression analysis was performed. With regard to the overall achievement of targets, it was observed that the majority of CDS (69.25%) performance was considered poor/regular. The independent factors associated with poor/regular performance of CDS were: municipalities belonging to the Northeast, South and Southeast regions, with lower Human Development Index (HDI), lower population density, and reduced time to deployment. HDI and population density are important for the performance of the CDS in Brazil. Similarly, the peculiarities related to less populated areas as well as regional location and time of service implementation CDS should be taken into account in the planning of these services.

School performance and oral health conditions: analysis of the impact mediated by socio-economic factors

BACKGROUND

Oral problems can cause strong impact on functional, emotional, and social aspects of children and adolescents, as well as changes in school performance.

AIM

To evaluate the associations of subjective perceptions of parents, socio-economic factors, and oral clinical conditions of children with their school performance.

DESIGN

A case-control design was used with a sample of 1411 schoolchildren aged 8-10 years from city of Piracicaba, São Paulo, Brazil. Clinical conditions were evaluated using the DMFT and dmft indexes. Socio-economic data were obtained using a questionnaire sent to schoolchildren's parents. School performance was evaluated by the final scores of each schoolchild at the end of the 2011 school year.

RESULTS

According to the final logistic regression model, the schoolchildren who had carious lesions and underwent curative dental treatment at the beginning of the academic year presented 1.51 more chance of having low performance compared with schoolchildren who had no caries lesions. In addition, socio-economic and demographic variables were associated with a greater chance of poor school performance.

CONCLUSION

Socio-economic factors and presence of caries lesions, even if treated, were risk indicators for poor school performance.

The impact of social determinants on schoolchildren's oral health in Brazil

The aim of this study was to evaluate the impact of socioeconomic status, home environment, and self-perception of health conditions on schoolchildren's dental caries experience. A total of 515 twelve-year-old schoolchildren from Juiz de Fora, State of Minas Gerais, Brazil, were selected into a random multistage sample. The schoolchildren were examined for the presence of caries lesions using the decayed/missing/filled teeth (DMFT) index and categorized as caries-free (DMFT = 0) or with caries experience (DMFT > 0). The participants and their parents were asked to answer a questionnaire about socioeconomic status, home environment, and self-perception of their health conditions. The hierarchical multiple regression model was used to assess the associations, since a binary response variable was assumed. The bivariate analysis revealed that variables at four levels, such as type of school, monthly family income, parents' education, home ownership, number of people living in the household, household overcrowding, parents' perception of their children's oral health, and schoolchildren's self-perception of their oral health (p < 0.05), were significantly associated with children's worse dental caries conditions. The regression model results showed that type of school and monthly family income had a strong negative effect on schoolchildren's dental caries experience (p < 0.05) in the final statistical model, where all levels were included. It was observed that socioeconomic factors were considered a strong risk indicator of schoolchildren's caries experience among the investigated social determinants of oral health.

Qualitative study on adolescents' reasons to non-adherence to dental treatment

The study aimed to reflect on adolescents' speeches regarding their justifications for non-adherence to dental treatment. This is a qualitative research derived from a quantitative research aimed at adolescents from 15 to 19 years of public schools belonging to the area of 34 Primary Health Units - Family Health, in Piracicaba, SP, in 2012. The adolescents were evaluated, diagnosed and referred for dental treatment. One year after this intervention and with non-adherence to treatment, we used a qualitative method to deeply understand this phenomenon. We conducted 25 interviews with a semi-structured script, divided into three blocks: adopted or did not adopt actions recommended; arguments justifying the non-adherence of recommended actions; dimensions related to oral health importance. We adopted the thematic analysis and non-adherence was related to some aspects and grouped in: no priority; priority and change of priority. We concluded that the main reasons for non-adherence are related to different priorities, and orthodontic brace was a potent stimulator of interest and establishment of priorities in oral health care among adolescents.

Evaluation of knowledge of Oral Health of Community Health Agents connected with the Family Health Strategy

The aim of this study was to evaluate the knowledge of Community Health Agents (CHA) about the oral health/disease process, and compare the results between those who work in Family Health Teams (FHT), with and without Oral Health Teams (OHT). The participants in this study were 162 subjects, representing 66% of the total number of CHA in the municipality, and 81 of them are connected with Family Health Units (FHU) with OHT, and 81 CHS with FHUs without OHT. Data were collected from October to December 2013, by application of a questionnaire, containing personal and professional data, and 12 validated questions about knowledge of the oral health/disease process. The Mann-Whitney test was applied to verify differences between the groups. Statistically significant differences were verified between the groups of CHA when the total scores of questions about the oral health/disease process were analyzed (p < 0.0021). It was concluded that knowledge about the oral health/disease process, of the CHAs connected with a FHU with an OHT was better when compared with that of CHAs connected with a FHU without an OHT.

Undergraduate dental students' perspectives about experiences in primary care for their education in the field of health

Supervised training periods in primary care have been used as spaces for teaching and extension in the area of health, making it feasible to include undergraduates in concrete teaching-learning scenarios. The aim of this study was to analyze the perceptions of dental students about the importance of supervised training periods in Family Health Units to their professional education. The sample consisted of 185 students who answered the question: What is your opinion about the importance of this training period in SUS to your professional education? Comment on this experience and its positive and negative aspects The responses were analyzed by the quali-quantitative Collective Subject Discourse (CSD) technique. The students appreciated learning through practice in the service; contact with professionals from other areas; opportunity for technical-operative improvement and demonstrated sensitivity in the face of social reality, although they appeared to be concerned about being absent from the faculty, arguing that they were being prejudiced as regards their intramural clinical productivity, exhaustively demanded of them. It was concluded that students placed value on the extramural experience, however, it was perceived that there was still a predominant influence of focus on intramural clinical training.

The impact of oral health conditions, socioeconomic status and use of specific substances on quality of life of addicted persons

BACKGROUND

The aim of this cross-sectional study was to evaluate the impact of oral health conditions, socioeconomic status and use of specific substances on quality of life of alcohol and drug addicted persons, receiving care at outpatient treatment facilities in Brazil.

METHODS

A random sample of 262 participants, mean age 37 years, from Psychosocial Care Centers for Alcohol and Drugs (CAPS AD) located in three cities in the state of São Paulo, Brazil, were clinically examined for caries experience (DMFT index) by a calibrated examiner. They were asked to complete a series of questionnaires, including the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST), socioeconomic characteristics, and the World Health Organization Quality of Life assessment (WHOQOL), which were considered the outcome variables of the study. Associations between oral health status, socioeconomic characteristics, substance involvement with WHOQOL were investigated by means of the chi-square test and multiple logistic regression analysis with a level of significance α < 0.05.

RESULTS

The mean DMF index of the group was 13.0. Subjects with DMFT >14 (OR = 2.25; CI 95% = 1.30-3.89); low-income (OR = 2.41; CI 95% = 1.22-4.77) and users of cocaine/crack (OR = 2.02; CI 95% = 1.15-3.59) were more likely to have poor general quality of life.

CONCLUSION

This study demonstrated that the general quality of life of addicted persons was associated with caries experience, low income and cocaine/crack use.

[Impact of the activation of intention to perform physical activity in type II diabetics: a randomized clinical trial]

Type II diabetes mellitus is a highly prevalent disease among the adult Brazilian population, and one that can be controlled by interventions such as physical activity, among others. The aim of this randomized controlled study was to evaluate the impact of a traditional motivational strategy, associated with the activation of intention theory, on adherence to physical activity in patients with type II, diabetes mellitus who are part of the Unified Health System (SUS). Participants were divided into a control group (CG) and an intervention group (IG). In both groups, the traditional motivational strategy was applied, but the activation of intention strategy was only applied to the IG Group. After a two-month follow-up, statistically significant differences were verified between the groups, related to the practice of walking (p = 0.0050), number of days per week (p = 0.0076), minutes per day (p = 0.0050) and minutes walking per week (p = 0.0015). At the end of the intervention, statistically significant differences in abdominal circumference (p = 0.0048) between the groups were observed. The conclusion drawn is that the activation of intention strategy had greater impact on adherence to physical activity and reduction in abdominal circumference in type II diabetics, than traditional motivational strategy.

Gingivitis and oral health-related quality of life: a literature review

<p><strong>Objective:</strong> The aim of this study was to review the literature about the relationship between gingivitis and oral health-related quality of life (OHRQoL). <strong>Material and methods:</strong> Relevant databases were searched for articles in English, which had been published from October 1990 to February 2014. Two independent examiners selected relevant papers, by initially assessing the abstracts and subsequently the full-text articles. Selected studies were grouped based on clinical and OHRQoL instruments and submitted to qualitative analyses. <strong>Results:</strong> Out of 184 references, twelve were eligible for synthesis. All studies were cross-sectional and reported data from the following five different countries: Chile (n=2), India (n=1), Brazil (n=3), Thailand (n=5) and Sudan (n=1). The number and age of subjects included ranged from 53 to 9133 and from eight to 106 years, respectively. The following six OHRQoL instruments were used: Oral Health Impact Profile (OHIP), OHIP-14, Child Perceptions Questionnaire (CPQ), Oral Impacts on Daily Performance (OIDP), Child-OIDP and Geriatric Oral Health Assessment Index (GOHAI). The different methods to evaluate the presence of gingivitis were: necrotizing ulcerative gingival lesions (n=2), Gingival Index (n=2), Community Periodontal Index (n=7) and gingival bleeding after tooth brushing (n=1). <strong>Conclusion:</strong> This literature review suggests that gingivitis is associated with impairment of OHRQoL. </p>

Estratégias para o enfrentamento do absenteísmo em consultas odontológicas nas Unidades de Saúde da Família de um município de grande porte: uma pesquisa-ação

O objetivo deste trabalho foi analisar os motivos das faltas às consultas odontológicas em Unidades de Saúde da Família (USF) e implementar estratégias para sua redução por meio da pesquisa-ação. O estudo foi realizado em 12 USF de Piracicaba/SP, de 01 de janeiro a 31 de dezembro de 2010. A amostra se consistiu de 385 usuários, entrevistados por telefone, sobre os motivos das faltas, além de 12 cirurgiões-dentistas e 12 enfermeiras. Realizaram-se duas oficinas com os profissionais: uma para problematização dos dados coletados nas entrevistas e elaboração de estratégias; e outra após 4 meses, para avaliação. O maior motivo de faltas foi a coincidência do horário de funcionamento das unidades com o de trabalho dos usuários. Dentre as estratégias ressaltou-se a realização de palestras sobre saúde bucal, educação permanente nas reuniões de equipe, capacitação dos Agentes Comunitários de Saúde, participação em grupos terapêuticos e parcerias entre Equipe de Saúde Bucal e equipamentos sociais da comunidade. A adoção de prontuário único foi a estratégia desafiadora encontrada pelos profissionais. Concluiu-se que as estratégias implementadas levaram à diminuição das faltas em 66,6% e o caráter motivador das oficinas possibilitou a reflexão crítica para o redirecionamento da prática em saúde.
