Oral health and social and emotional well-being in a birth cohort of Aboriginal Australian young adults

Aboriginal and Torres Strait Islander youth suicide mortality and previous mental health, suicidality and service use in Queensland, Australia, from 2001 to 2021

BACKGROUND

The current study aimed to compare current suicide rates, trends, previous treatment, suicidality and mental health diagnoses for First Nations and non-Indigenous young people who died by suicide.

METHODS

Age-specific suicide rates (ASSRs) were calculated per 100,000 persons/year using suicides aged 10-19 years in the Queensland Suicide Register. Rate Ratios (RRs) and 95 % CIs compared ASSRs for First Nations and non-Indigenous youth dying by suicide in Queensland, Australia, from 2001 to 2018. Risk ratios (RiskR) with 95 % CIs compared characteristics between First Nations and non-Indigenous youth suicides. Joinpoint regression was used to identify any changes in trends and annual percentage change (APC) in suicides with 95 % CIs.

RESULTS

The First Nations youth ASSR was 24.71 deaths per 100,000 persons/year, 4.5 times the non-Indigenous ASSR (95 % CI = 3.74-5.38, p < 0.001). Both non-Indigenous and First Nations suicide trends were stable with no joinpoints (APC: 0.3 %, 95 % CI: -1.6-2.2, p = 0.78; APC: 0.9 %, 95 % CI: -0.2-2.1, p = 0.11). Less than a quarter (23.9 %) of First Nations young people had ever received mental health treatment, significantly fewer than non-Indigenous youth (RiskR = 0.80, 95 % CI = 0.71-0.90, p < 0.001). Similarly, in the three months preceding their death, only 14.5 % of First Nations young people had received mental health treatment (RiskR = 0.89, 95 % CI = 0.83-97, p = 0.015).

LIMITATIONS

Reported mental illness, suicidality and help-seeking could be underreported due to concealment from family or police.

CONCLUSIONS

The current study finds no change in the gap between the First Nations and Non-Indigenous youth suicide rates nor evidence of decrease in the First Nations youth suicide rate. There is a need for alternative approaches to Indigenous youth suicide prevention, such as assertive outreach models outside of traditional triage and mental health systems to proactively build trusting relationships with young people in communities to identify young people needing support.

A Silver Fluoride Intervention to Improve Oral Health Trajectories of Young Indigenous Australians: Protocol for a Cluster Randomized Controlled Trial

BACKGROUND

Indigenous Australian children and adolescents experience profound levels of preventable dental disease. The application of silver fluoride (AgF) to active dental caries is a noninvasive alternative to traditional dental treatment approaches. There is particular utility among Indigenous children and young people with dental fear, who may not have access to timely or culturally safe dental service provisions.

OBJECTIVE

The aims of this study are to: (1) assess levels of active dental caries among Indigenous children and young people in 6 Australian states and territories; (2) determine if an AgF intervention reduces levels of active disease over 12-24 months; (3) measure the impact of improved oral health on social and emotional well-being (SEWB) and oral health-related quality of life; and (4) calculate the cost-effectiveness of implementing such an initiative.

METHODS

The study will use a 2-arm, parallel cluster randomized controlled trial design. Approximately 1140 Indigenous children and youth aged between 2 and 18 years will be recruited. Each state or territory will have 2 clusters. The intervention group will receive the AgF intervention at the start of the study, with the delayed intervention group receiving the AgF intervention 12 months after study commencement. The primary outcome will be the arrest of active carious lesions, with arrested caries defined as nonpenetration by a dental probe. Secondary outcomes will include SEWB, oral health-related quality of life, and dental anxiety, with covariates including dental behaviors (brushing and dental visits). Effectiveness measures for the economic evaluation will include the number of children and young people managed in primary oral health care without the need for specialist referral, changes in SEWB, the numbers and types of treatments provided, and caries increments.

RESULTS

Participant recruitment will commence in May 2023. The first results are expected to be submitted for publication 1 year after a 24-month follow-up.

CONCLUSIONS

Our findings have the potential to change the way in which active dental disease among Indigenous children and young people can be managed through the inclusion of specifically tailored AgF applications to improve dental health and SEWB delivered by Indigenous health care workers. Desired impacts include cost savings on expensive dental treatments; improved SEWB, nutrition, social, and learning outcomes; and improved quality of life for both children and young people and their caregivers and the broader Indigenous community. The AgF application could be easily implemented into the training program of Indigenous health workers and yield critical information in the management armamentarium of health and well-being recommendations for Australia's First Peoples.

The relationship between oral health status, loneliness, and sleep quality among the migrant elderly following children in Weifang, Shandong Province, China: A comparative analysis on different migration types

Background

The migrant elderly following children (MEFC) are a vulnerable group that emerged during fast urbanization in China. The MEFC faced physical and psychological discomfort upon their arrival in the inflow city, particularly those who came from rural areas.

Objective

This study aimed to explore the relationship between oral health status, loneliness, and sleep quality among the MEFC in China and to clarify the disparities in the above mentioned relationship by migration type.

Methods

In 2021, a cross-sectional survey was conducted in Weifang, Shandong Province, using multistage cluster random sampling to collect data from the MEFC aged 60 years and over. In total, 613 respondents [525 rural-to-urban (RTU) and 88 urban-to-urban (UTU)] were included in the final database. The chi-square test, t-test, and structural equation modeling (SEM) were used to investigate the relationship between oral health status, loneliness, and sleep quality among the RTU and UTU MEFC.

Results

Total scores [mean ± standard deviation (SD)] for oral health status, loneliness, and sleep quality were 54.95 ± 6.47, 8.58 ± 3.03, and 4.47 ± 3.60, respectively. SEM revealed that, among the RTU and UTU MEFC, oral health status was positively and significantly related to sleep quality; however, the correlation was slightly stronger in the UTU MEFC. In both groups, there was a significant negative correlation between oral health status and loneliness, which was stronger in the UTU MEFC. In the RTU MEFC, a significant negative correlation between loneliness and sleep quality was observed, and in the UTU MEFC, no significant association between loneliness and sleep quality was observed.

Conclusion

The sleep quality among the MEFC in this study was higher compared to previous studies. Oral health status was negatively correlated with loneliness and positively associated with sleep quality, whereas loneliness was negatively correlated with sleep quality. These three associations differed significantly between the UTU and RTU MEFC. The government, society, and families should take measures to improve oral health and reduce loneliness among the MEFC to improve their sleep quality.

Psychological factors and oral health during initial outbreak of COVID-19 in China: A cross-sectional study

OBJECTIVES

To investigate associations between oral health and psychological factors (i.e., depression, anxiety, and resilience) in a group of Chinese individuals who had sought an intervention online during the COVID-19 pandemic.

METHODS

For this cross-sectional study, online questionnaires were created using online survey software from set items of instruments commonly used to assess depression, anxiety, and resilience combined with an oral health survey. The study was conducted from March 13 to 16, 2020.

RESULTS

568 participants (188 men and 380 women) with a mean ± SD age of 41.7 ± 10.2 years were included in the analyses. In total, 152 (27%) participants were from Beijing, 149 (26%) from Wuhan, 110 (19%) from Shenyang, and 157 (28%) from other Chinese cities. Halitosis and bleeding gums were the most common reasons for individuals to seek an intervention. Compared with other cities, participants from Wuhan showed higher anxiety and depression and worse previous oral health. Resilience mediated the relationship between depression and oral health, but not between anxiety and oral health.

CONCLUSION

We hope that the data from this study will inform clinical practitioners and demonstrate that mental health awareness and resilience training are important strategies that may mitigate the negative impact of lockdown and isolation on oral health.

Prevalence Rates of Depression and Anxiety among Young Rural and Urban Australians: A Systematic Review and Meta-Analysis

Globally, depression and anxiety are major public health concerns with onset during adolescence. While rural Australia experiences overall lower health outcomes, variation in mental health prevalence rates between rural and urban Australia is unclear. The aim of this paper was to estimate the pooled prevalence rates for depression and anxiety among young Australians aged between 10 and 24 years. Selected studies from a systematic literature search were assessed for risk of bias. Random effects model using DerSimonian and Laird method with Freeman-Tukey Double Arcsine Transformation was fitted. Sensitivity analyses were performed. Prevalence estimates were stratified by region and disorder. The overall pooled prevalence of depression and anxiety was 25.3% (95% CI, 19.9-31.0%). In subgroup analysis, anxiety prevalence was 29.9% (95% CI, 21.6-39.0%); depression: 21.3% (95% CI, 14.9-28.5%); and depression or anxiety: 27.2% (95% CI, 20.3-34.6%). Depression and anxiety prevalence were higher in urban 26.1% (95% CI, 17.3-35.9%) compared to rural areas 24.9% (95% CI, 17.5-33%), although the difference was not statistically significant. The heterogeneity was high with an I² score of 95.8%. There is need for further research on healthcare access, mental health literacy and help-seeking attitude in Australia.

“Oral health as an important milieu for social and mental health”: Perspectives of adolescents emerging from a qualitative study

Background

Recent evidence showed that the prevalence of oral diseases is still high among adolescents in many developing countries, including Nigeria. It therefore has becomes pertinent to focus on appropriate oral health interventions to promote oral health among them. This necessitates investigating the perspectives of adolescents, who are the major stakeholders, on the importance of oral health as baseline data needed in planning appropriate primary interventions.

Aim

The aim of the study was to explore the perspectives of adolescents on the importance of oral health.

Methods

An explorative qualitative study was conducted among adolescents attending senior secondary school I (grade 10) in the metropolis of Ibadan, Nigeria. A total of 12 focus group discussions were conducted among 120 adolescents aged 14 to 19 years. The discussions were transcribed verbatim, and triangulation and organization, as well as thematic analysis, of data were carried out.

Results

Some adolescents had positive perceptions of oral health and valued it as highly important, although some had contrary views and believed oral health was unimportant. Oral health is described as being integral to general health, is associated with eating and communication, is a means of survival and confidence building, and is a prelude to attract the opposite gender. Adolescents perceived the need for oral health education and dental treatment.

Conclusion

Adolescents have mixed perspectives on the importance of oral health; while some valued it as highly important, others believed it was of no significance. Those who valued oral health as important described it as a milieu for general health, human survival, and social and mental health and thus requested for oral health promotion in schools.

The Indigenous Adolescent Oral Health Partnership Study: A Co-Design Study Protocol

Background: in this protocol we outline a method of working alongside Aboriginal communities to learn about and facilitate improvement in the oral health habits in Aboriginal adolescents. By facilitating positive oral health in Aboriginal adolescents, we hope to achieve lifelong improvement in oral health and general wellbeing. Methods: this paper outlines a co-design methodology through which researchers and Aboriginal communities will work together to create a custom oral healthcare program aimed at Aboriginal adolescents. Researchers, a youth advisory group, Aboriginal community-controlled health services and three regional NSW communities will together devise an oral health strategy focused on five components: application of topical fluoride, increasing water consumption, improving nutrition, daily toothbrushing, and enhancing social and emotional wellbeing. Capacity building is a key outcome of this program. Discussion: as the gap in health status between Aboriginal and non-Aboriginal people remains wide, it is clear that new approaches and attitudes are needed in Aboriginal public health research. This protocol is representative of this shifting approach; giving power to Aboriginal communities who seek to have sovereignty and self-determination over their healthcare.

Bullied Because of Their Teeth: Evidence from a Longitudinal Study on the Impact of Oral Health on Bullying Victimization among Australian Indigenous Children

Making life better for Indigenous peoples is a global priority. Although bullying and oral health have always been a topic of concern, there is limited information regarding the impact of this problem on the general population, with no evidence in this regard among the Australian Indigenous population. Thus, we aimed to quantify the relationship between bullying victimization and oral health problems by remoteness among 766 Australian Indigenous children aged between 10−15-years using data from the LSIC study. Bivariate and multilevel mixed-effect logistic regression analyses were employed. Findings indicated children self-reported bullying more than parents reported their children were being bullied (44% vs. 33.6%), with a higher percentage from rural/remote areas than urban areas. Parents reported that oral health problems increased the probability (OR 2.20, p < 0.05) of being bullied, in Indigenous children living in urban areas. Racial discrimination, lower level of parental education and poor child oral hygiene increase the risk of bullying victimization. Parental happiness with life and a safe community were associated with a lower risk of bullying. Dental problems are linked with Australian Indigenous children experiencing bullying victimization. Cultural resilience and eliminating discrimination may be two modifiable paths to ameliorating health issues associated with bullying in the Australian Indigenous community.

Association of Dental Fear with Caries Status and Self-Reported Dentition-Related Well-Being in Finnish Conscripts

The main aim of this cross-sectional study was to examine the prevalence of dental fear among Finnish conscripts. Other aims were to study the association between dental fear and cariological status as well as their self-reported, dentition-related well-being. The study material consisted of 13,564 men and 255 women conscripts who underwent oral examinations. Of those, 8713 responded to a computer-based questionnaire. The mean number of decayed teeth (DT) was used in analyses for cariological status. Self-reported dental fear, dentition-related well-being and regular check-ups were analysed. Data were analysed with cross tables, Pearson Chi-Square tests, Fisher’s exact test and binary logistic regressive analysis. High dental fear or finding dental visits very scary was associated with DT > 2 both among women (14.6%, when DT = 0; 33.3%, when DT > 2) and men conscripts (2.3% and 10.8%, respectively). In addition, those reporting that dental health had a negative impact on their well-being and had no regular check-ups were more likely to need cariological treatment than the rest. A high education level, both one’s own and parental, was a protective factor for restorative treatment need in male conscripts. The findings of this study support the concept of a vicious cycle of dental fear and dental caries. A preventive, interactive way of work by dental teams would most likely be beneficial for dental health, avoiding the development of dental fear, and dentition-related well-being.

Child-, Family-, and Community-Level Facilitators for Promoting Oral Health Practices among Indigenous Children

Despite the preventive nature of oral diseases and their significance for general wellbeing, poor oral health is highly prevalent and has unfavourable ramifications for children around the world. Indigenous children in Australia experience disproportionate rates of early childhood caries compared to their non-Indigenous counterparts. Therefore, this paper aims to collate parental experiences and generate an understanding of facilitators for Indigenous childhood oral health. This project aggregated stories from parents of Indigenous children across South Australia who were participants in an early childhood caries-prevention trial. This paper explores facilitators for establishing oral health and nutrition behaviours for Indigenous children under the age of three through reflexive thematic analysis. Fisher-Owens' conceptual model for influences on children's oral health is utilised as a framework for thematic findings. Child-level facilitators include oral hygiene routines and regular water consumption. Family-level facilitators include familial ties, importance of knowledge, and positive oral health beliefs. Community-level facilitators include generational teaching, helpful community resources, and holistic health care. Recommendations from findings include the following: exploration of Indigenous health workers and elder participation in oral health initiatives; inclusion of Indigenous community representatives in mainstream oral health discussions; and incorporation of child-level, family-level, and community-level facilitators to increase support for efficacious oral health programs.

"Does this dental mob do eyes too?": perceptions and attitudes toward dental services among Aboriginal Australian adults living in remote Kimberley communities

BACKGROUND

Australian Aboriginal and Torres Strait Islander people continue to experience significant disparities in oral health and there remains an urgent need to improve services to rural and remote communities. Quantitative research has typically been used to highlight the disease burden and severity experienced by those living in remote communities, but this data does little to explore the lived reality and psychosocial nuances that impact on care. The Kimberley region of Western Australia is home to over 150 Aboriginal communities spread out across 400,000 square kilometres. The success and sustainability of oral health services to these remote communities relies on respect and reciprocity achieved through shared knowledge, decision making and involvement of Aboriginal people in discussions around oral health services and their delivery. This, study aimed to investigate the perceptions and attitudes toward dental services among Aboriginal Australian families living in remote Kimberley communities.

METHODS

Semi-structured interviews and yarning circles were carried out following purposive sampling of Aboriginal adults living in the East Kimberley region of Western Australia. Interviews were recorded, transcribed, and analysed guided by a constructivist grounded theory approach.

RESULTS

In total, 80 community members participated in the yarning process. Enablers to care included: promotion of existing services, integration with primary health services, using mobile dental services and volunteers to extend care. Barriers to care included transportation, cost of treatment, the complexity of appointment systems and shame associated with health-seeking behaviours.

CONCLUSIONS

Reassessing the prevailing operative model of dental care to remote Aboriginal communities is warranted to better address the overwhelming structural barriers that impact on oral health. Integration with existing primary health services and schools, the use of mobile units to extend care and increasing community engagement through clinical yarning are recommended in improving the current state of dental services to communities in the Kimberley.

Does community cultural connectedness reduce the influence of area disadvantage on Aboriginal & Torres Strait Islander young peoples' suicide?

OBJECTIVE

The study aimed to examine associations of community cultural connectedness with Aboriginal and Torres Strait Islander young peoples' suicide rates in areas with elevated risk factors.

METHODS

Age-specific suicide rates (ASSRs) were calculated using suicides recorded by the Queensland Suicide Register (QSR) of Aboriginal and Torres Strait Islander young people (aged 15-24 years) in Queensland from 2001-2015. Rate Ratios (RRs) compared young peoples' suicide rates in areas with high and low levels of cultural connectedness indicators (cultural social capital and Indigenous language use) within areas with elevated risk factors (high rates of discrimination, low socioeconomic resources, and remoteness).

RESULTS

Within low socioeconomically resourced areas and where Aboriginal and Torres Strait Islander people experienced more discrimination, greater engagement and involvement with cultural events, ceremonies and organisations was associated with 36% and 47% lower young peoples' suicide rates respectively (RR=1.57, 95%CI=1.13-2.21, p=<0.01; RR=1.88, 95%CI=1.25-2.89, p=<0.01). Within remote and regional areas, higher levels of community language use was associated with 26% lower suicide rates (RR=1.35, 95%CI=1-1.93, p=0.04), and in communities experiencing more discrimination, language use was associated with 34% lower rates (RR=1.53, 95%CI=1.01-2.37, p=0.04).

CONCLUSION

Cultural connectedness indicators were associated with lower Aboriginal and Torres Strait Islander young peoples' suicide rates in communities experiencing the most disadvantage. Implications for public health: This provides initial evidence for trialling and evaluating interventions using cultural practices and engagement to mitigate against the impacts of community risk factors on Aboriginal and Torres Islander suicide.

Bitter and sweet taste perception: relationships to self-reported oral hygiene habits and oral health status in a survey of Australian adults

Background

Oral health, an essential part of general health and well-being, is influenced by multiple factors, including oral hygiene habits and dietary factors. Dietary preferences are influenced by variation in taste perceptions and threshold tasting. Polymorphisms in specific genes for sweet and bitter taste receptors and bitter taste perception have been associated with dental caries. However, taste is complex with multiple receptors, each with multiple potential polymorphisms contributing to taste perception as well as social, cultural, and environmental influences. Additionally, these association studies have been conducted in restricted cohorts (e.g., children only). Furthermore, outcomes have been limited to dental caries and studies between taste perception and oral hygiene habits have not been completed.

Methods

A cross-sectional online survey was conducted to investigate the relationships between bitter and sweet taste perception (liking and intensity of index food items), self-reported oral hygiene habits and oral health (n = 518).

Results

Higher mean intensity scores for bitter (16–21%) and sweet (< 5%-60%) were seen with higher frequencies of oral hygiene habits (brushing, use of mouthwash, chewing gum and tongue cleaning). Lower mean bitter liking scores (18–21%) were seen with higher frequencies of oral hygiene habits (brushing, mouthwash use, floss use and chewing gum). Sweet liking scores varied by reported frequency of mouthwash use and flossing only, with mixed patterns of variance. Mean bitter and sweet intensity perception scores varied with the number of dental caries ((13–20% higher in those with 3 or more caries, compared to none).

Conclusions

While there were numerous relationships identified between liking and perception of sweet and bitter and oral health outcomes, the magnitude and direction of associations varied by outcome. The direction of the associations cannot be inferred due to the cross-sectional nature of the study. The demonstrated relationships justify further future investigations, which could help better understand if taste liking and perception is impacted by oral hygiene and health, or vice versa. This could be important in understanding the causation and progression of oral health diseases or the development of novel therapeutics for oral health.

Experiences of Racism among Older Aboriginal and Torres Strait Islander People: Prevalence, Sources, and Association with Mental Health

Cet article présente une analyse inédite de l'association entre la discrimination raciale et la détresse psychologique chez les personnes âgées indigènes et insulaires du détroit de Torres. Les résultats indiquent : (1) qu'une minorité importante d'aînés appartenant aux populations indigènes et insulaires du détroit de Torres ont été victimes de racisme (tel qu'expérimenté et mesuré en fonction d'inégalités de traitement) et d'évitement ; (2) qu'une association entre les expériences de racisme ou d'évitement et la détresse psychologique peut être mise en évidence, et que cette relation demeure robuste malgré la considération d'une variété de facteurs confondants et de caractéristiques complexes associées à la conception des enquêtes ; et (3) les associations entre le racisme et la détresse sont amplifiées en fonction de l'intensité du racisme et des comportements d'évitement. L'association reste robuste ou se trouve renforcée lorsque le racisme et l'évitement se produisent dans le cadre de contextes cruciaux au développement du capital humain des personnes âgées (p. ex. soins de santé, éducation, milieu de travail). Nos résultats soulignent l'importance des programmes et des services sociaux et de santé culturellement sécuritaires, ainsi que la nécessité de contrer la discrimination sous toutes ses formes.

This article presents the first nationally representative analysis of the association between racial discrimination and psychological distress among older Aboriginal and Torres Strait Islander people. Results show: (1) experiences of racism (as measured by unfair treatment) and avoidance are encountered by a significant minority of older Aboriginal and Torres Strait Islander people; (2) there is a clear association between experiences of racism and avoidance with psychological distress, with these results being robust to a range of confounding factors and complex survey design features; and (3) the associations between racism and distress are amplified by the severity of racism, and, when occurring, with avoidance. The association remains strong or is strengthened when racism and avoidance occur in contexts or situations crucial to the human capital development of older people (e.g., health care, education, and the workplace). Our findings underscore the importance of culturally safe health and social services/programs and further the imperative to address discrimination in all its forms.

Oral health practices and oral hygiene status as indicators of suicidal ideation among adolescents in Southwest Nigeria

Background

Oral health is a less-recognized correlate of overall and mental wellbeing. This study aimed to assess the relationship between suicidal behavior (ideation and attempt) and oral health practices and status, and to determine the effect of sex on these associations among Nigerian adolescents.

Methods

Household survey data were collected from 10 to 19-year-old adolescents in southwestern Nigeria. Dependent variables were daily tooth brushing, daily consumption of refined carbohydrates between meals, and oral hygiene status (measured by plaque index). The independent variable was lifetime suicidal ideation/attempt, dichotomized into ‘yes’ and ‘never’. ‘Daily tooth brushing’ and ‘daily consumption of refined carbohydrates between meals’ were included in two separate logistic regression models, and ‘oral hygiene status’ was included in a linear regression model. The models were adjusted for sex, age, and socioeconomic status. The linear regression model was also adjusted for frequency of daily tooth-brushing and of consumption of refined carbohydrates between meals. Interactions between sex and suicidal ideation/suicide attempt in association with dependent variables were assessed. Significance was set at 5%.

Results

We recruited 1,472 participants with mean age (standard deviation) of 14.6 (2.6) years. The mean plaque index was 0.84 (0.56), and 66 (4.5%) adolescents reported ever having suicidal ideation/attempt. Suicidal ideation/attempt was associated with significantly lower likelihood of tooth brushing (OR = 0.48, 95% CI: 0.26, 0.91), higher likelihood of consuming refined carbohydrates between meals (OR = 2.30, 95% CI: 1.29, 4.10), and having poor oral hygiene (B = 0.18, 95% CI: 0.05, 0.32). Among males, suicidal ideation/attempt was associated with less likelihood of eating refined carbohydrates between meals (OR = 0.96, 95% CI: 0.35, 2.61). Conversely, it was associated with a significantly higher likelihood of this outcome (OR = 4.85, 95% CI: 2.23, 10.55) among females.

Conclusion

The study findings suggest that poor tooth brushing habits and poor oral hygiene are indicators for risk of suicidal behavior for adolescents in Nigeria, while high sugar consumption may be an additional risk factor for adolescent females. These findings support the role of dental practitioners as members of healthcare teams responsible for screening, identifying and referring patients at risk for suicidal ideation/attempt.

The impact of interpersonal racism on oral health related quality of life among Indigenous South Australians: a cross-sectional study

Background

Interpersonal racism has had a profound impact on Indigenous populations globally, manifesting as negative experiences and discrimination at an individual, institutional and systemic level. Interpersonal racism has been shown to negatively influence a range of health outcomes but has received limited attention in the context of oral health. The aim of this paper was to examine the effects of experiences of interpersonal racism on oral health-related quality of life (OHRQoL) among Indigenous South Australians.

Methods

Data were sourced from a large convenience sample of Indigenous South Australian adults between February 2018 and January 2019. Questionnaires were used to collect data on sociodemographic characteristics, cultural values, utilization of dental services, and other related factors. OHRQoL was captured using the Oral Health Impact Profile (OHIP-14) questionnaire. We defined the dependent variable 'poor OHRQoL' as the presence of one or more OHIP-14 items rated as ‘very often’ or ‘fairly often'. Experiences of racism were recorded using the Measure of Indigenous Racism Experiences instrument. Interpersonal racism was classified into two categories (‘no racism’ vs ‘any racism in ≥ 1 setting’) and three categories ('no racism', 'low racism' (experienced in 1–3 settings), and 'high racism' (experienced in 4–9 settings)). Logistic regression was used to examine associations between interpersonal racism, covariates and OHRQoL, adjusting for potential confounding related to socioeconomic factors and access to dental services.

Results

Data were available from 885 participants (88.7% of the total cohort). Overall, 52.1% reported experiencing any interpersonal racism in the previous 12 months, approximately one-third (31.6%) were classified as experiencing low racism, and one-fifth (20.5%) experienced high racism. Poor OHRQoL was reported by half the participants (50.2%). Relative to no experiences of racism in the previous 12 months, those who experienced any racism (≥ 1 setting) were significantly more likely to report poor OHRQoL (Odds Ratio (OR): 1.43; 95% Confidence Interval (CI): 1.08–1.92), after adjusting for age, education level, possession of an income-tested health care card, car ownership, self-reported oral health status, timing of and reason for last dental visit, not going to a dentist because of cost, and having no family support. This was particularly seen among females, where, relative to males, the odds of having poor OHRQoL among females experiencing racism were 1.74 times higher (95% CI: 1.07–2.81).

Conclusion

Our findings indicate that the experience of interpersonal racism has a negative impact on OHRQoL among Indigenous Australians. The association persisted after adjusting for potential confounding factors. Identifying this link adds weight to the importance of addressing OHRQoL among South Australian’s Indigenous population by implementing culturally-sensitive strategies to address interpersonal racism.

Racial discrimination and allostatic load among First Nations Australians: a nationally representative cross-sectional study

BACKGROUND

Increased allostatic load is linked with racial discrimination exposure, providing a mechanism for the biological embedding of racism as a psychosocial stressor. We undertook an examination of how racial discrimination interacts with socioecological, environmental, and health conditions to affect multisystem dysregulation in a First Nations population.

METHODS

We conducted latent class analysis (LCA) using indicators of life stress, socioeconomic background, and physical and mental health from a nationally representative sample of Australian Aboriginal adults (N = 2056). We used LCA with distal outcomes to estimate the effect of the latent class variable on our derived allostatic load index and conducted a stratified analysis to test whether allostatic load varied based on exposure to racial discrimination across latent classes.

RESULTS

Our psychosocial, environmental, and health measures informed a four-class structure; 'Low risk', 'Challenged but healthy', 'Mental health risk' and 'Multiple challenges'. Mean allostatic load was highest in 'Multiple challenges' compared to all other classes, both in those exposed (4.5; 95% CI: 3.9, 5.0) and not exposed (3.9; 95% CI: 3.7, 4.2) to racial discrimination. Allostatic load was significantly higher for those with exposure to racial discrimination in the 'Multiple challenges' class (t = 1.74, p = .04) and significantly lower in the 'Mental health risk' class (t = - 1.67, p = .05).

CONCLUSIONS

Racial discrimination may not always modify physiological vulnerability to disease. Social and economic contexts must be considered when addressing the impact of racism, with a focus on individuals and sub-populations experiencing co-occurring life challenges.

How Neoliberalism Shapes Indigenous Oral Health Inequalities Globally: Examples from Five Countries

Evidence suggests that countries with neoliberal political and economic philosophical underpinnings have greater health inequalities compared to less neoliberal countries. But few studies examine how neoliberalism specifically impacts health inequalities involving highly vulnerable populations, such as Indigenous groups. Even fewer take this perspective from an oral health viewpoint. From a lens of indigenous groups in five countries (the United States, Canada, Australia, Aotearoa/New Zealand and Norway), this commentary provides critical insights of how neoliberalism, in domains including colonialism, racism, inter-generational trauma and health service provision, shapes oral health inequalities among Indigenous societies at a global level. We posit that all socially marginalised groups are disadvantaged under neoliberalism agendas, but that this is amplified among Indigenous groups because of ongoing legacies of colonialism, institutional racism and intergenerational trauma.

The role of the oral microbiota in chronic non-communicable disease and its relevance to the Indigenous health gap in Australia

BACKGROUND

Aboriginal Australians and Torres Strait Islanders (hereafter respectfully referred to as Indigenous Australians) experience disproportionately poor health and low life expectancy compared to non-Indigenous Australians. Poor oral health is a critical, but understudied, contributor to this health gap. A considerable body of evidence links poor oral health to increased risks of other chronic non-communicable conditions, such as diabetes, cardiovascular disease, chronic kidney disease, and poor emotional wellbeing.  MAIN: The oral microbiota is indisputably associated with several oral diseases that disproportionately affect Indigenous Australians. Furthermore, a growing literature suggests direct and indirect links between the oral microbiota and systemic chronic non-communicable diseases that underpin much of the Indigenous health gap in Australia. Recent research indicates that oral microbial communities are shaped by a combination of cultural and lifestyle factors and are inherited from caregivers to children. Systematic differences in oral microbiota diversity and composition have been identified between Indigenous and non-Indigenous individuals in Australia and elsewhere, suggesting that microbiota-related diseases may be distinct in Indigenous Australians.  CONCLUSION: Oral microbiota research involving Indigenous Australians is a promising new area that could benefit Indigenous communities in numerous ways. These potential benefits include: (1) ensuring equity and access for Indigenous Australians in microbiota-related therapies; (2) opportunities for knowledge-sharing and collaborative research between scientists and Indigenous communities; and (3) using knowledge about the oral microbiota and chronic disease to help close the gaps in Indigenous oral and systemic health.

Association of state and trait anxiety with oral health status among adult dental patients

Background:

Dental caries and periodontal diseases are the most prevalent oral health problems worldwide. Behavioral and psychosocial factors along with social, economic and cultural conditions may alter the health balance, favoring the onset of dental diseases. Hence the study was conducted to assess the association of state and trait anxiety with oral health status among adult dental patients.

Methods:

The study was carried out among 456 adult dental patients visiting Panineeya Institute of Dental Sciences and Hospital, Hyderabad. Anxiety levels were measured by State-Trait Anxiety Inventory-short version (STAI-S) consisting subscales State Anxiety (SA) and Trait Anxiety (TA). Clinical examination was done using WHO Basic Oral Health survey assessment form, 2013. The data was analyzed using Statistical Package for Social Sciences Software 21.0. p≤0.05 was considered statistically significant.

Results:

A significant gender difference (p=0.001) was noted for total anxiety with higher mean score observed among males (46.13±5.98) than females (45.32±6.00).Similarly, significant higher mean score was observed among males (23.31±4.08) than females (p=0.03) for State anxiety. Females had higher mean DMFT (3.61±3.21), DT (2.04±2.05), FT (0.49±1.34) and MT (1.08±2.09) components but significant difference was noted only for overall DMFT (p=0.03) and DT (p=0.001) component than males.

Conclusion:

Gender, education and previous dental visits didn’t show any significant association with total anxiety, state and trait anxiety. Likewise, none of the oral parameters showed any significant association except for the Decayed Teeth (DT) component of DMFT with total anxiety levels among study subjects. (www.actabiomedica.it)

Factors influencing the perceived importance of oral health within a rural Aboriginal and Torres Strait Islander community in Australia

BACKGROUND

Indigenous Australians suffer from higher rates of oral disease and have more untreated dental problems and tooth extractions than the general population. Indigenous Australians also have lower rates of accessing oral health services and are more likely to visit for a problem rather than a check-up. Multiple issues effect health service and prevention programs including: characteristics of health services such as distances to health services; existence of social and cultural barriers; available wealth and social support; and, characteristics of the individual and community including the importance given to the disease. This paper seeks to explore the perceived importance of oral health within a rural Indigenous community in Australia and the factors influencing this perception.

METHODS

The study used a phenomenology research design incorporating focus group discussions and in-depth interviews. It was undertaken in partnership with communities' Health Action Group who guided the focus, implementation and reporting of the research. A convenience sample was recruited from established community groups. Thematic analysis on the transcripts was completed.

RESULTS

Twenty-seven community members participated in three focus groups and twelve in-depth interviews. The study found that the community gives high priority to oral health. Factors influencing the importance include: the perceived severity of symptoms of oral disease such as pain experienced due to tooth ache; lack of enabling resources such as access to finance and transport; the social impact of oral disease on individuals including impact on their personal appearance and self-esteem; and health beliefs including oral health awareness. Participants also noted that the importance given to oral health within the community competed with the occurrence of multiple health concerns and family responsibilities.

CONCLUSION

This paper highlights the high importance this rural Indigenous community gives to oral health. Its findings suggest that under-utilisation of oral health services is influenced by both major barriers faced in accessing oral health services; and the number and severity of competing health and social concerns within the community. The study results confirm the importance of establishing affordable, culturally appropriate, community-based oral health care services to improve the oral health of rural Indigenous communities.

Prevalence and Factors Associated with Visiting the Dentist Only for Emergency Care Among Indigenous People in Ontario

Ontario has the largest Indigenous population in Canada. This study aims to examine the prevalence and factors associated with poor dental care use amongst the Indigenous in Ontario. Data from the 2014 cycle of the Canadian Community Health Survey was used. The main outcome was defined as visiting the dentist only for emergency care. Stepwise multivariable logistic regression was performed to assess the association between socio-demographic, socio-economic, and the health related factors and emergency dental care use. 28% of the participants reported visiting the dentist only for emergencies. First Nations people were at increased odds of having poor dental care (OR 2.01, CI 1.12-3.95). Additionally, being male, a smoker, having fair/poor health and lacking dental insurance puts the Indigenous Ontarians at increased odds of having the outcome. Improvements to the current social benefit programs could help better cater to the needs of this population.

A systematic review of oral health in people with multiple sclerosis

OBJECTIVES

Despite more than 25 years of research focused on this topic, it remains unclear whether people with multiple sclerosis are more likely to present with oral health problems. The aim of this study was to provide the first systematic review of this literature.

METHODS

A literature search for studies focused on oral health and multiple sclerosis was conducted using PRISMA guidelines. Electronic databases (PubMed, Scopus, Web of Science, MEDLINE and CINAHL) were searched up until February 2019. Two independent coders extracted data, and study quality graded using the Newcastle-Ottawa Scale (NOS).

RESULTS

From 1281 articles identified, 17 met all the eligibility criteria. Of the seventeen studies, more than half included a nonclinical control group, and the majority were observational studies. The included studies were of poor to moderate quality. Taken together, the results provided only very limited evidence that people with multiple sclerosis are more likely to present with dental caries and gingival disease. There was suggestive evidence that people with multiple sclerosis may be at higher risk of periodontal disease and present with poorer oral hygiene, and moderate evidence for an association between multiple sclerosis and temporomandibular disorders.

CONCLUSIONS

This systematic review provides evidence of an association between multiple sclerosis and at least some oral health problems. When temporomandibular disorders and periodontal status specifically have been assessed, most studies provide evidence of an association with multiple sclerosis. However, this review also clearly highlights the need for further, high-quality studies in this area.

A Systematic Review of the Antecedents and Prevalence of Suicide, Self-Harm and Suicide Ideation in Australian Aboriginal and Torres Strait Islander Youth

Suicide and self-harm represent serious global health problems and appear to be especially elevated amongst indigenous minority groups, and particularly amongst young people (aged 24 years or younger). This systematic review investigates for the first time the antecedents and prevalence of suicide, self-harm and suicide ideation among Australian Aboriginal and Torres Strait Islander youth. Web of Science, PubMed, PsychINFO, CINAHL databases and grey literature were searched from earliest records to April 2019 for eligible articles. Twenty-two empirical articles met the inclusion criteria. The data confirmed that indigenous youth in Australia have elevated rates of suicide, self-harm and suicidal ideation relative to the nonindigenous population. Risk factors included being incarcerated, substance use and greater social and emotional distress. Notably, though, information on predictors of suicide and self-harm remains scarce. The findings support and justify the increasing implementation of public health programs specifically aimed at tackling this crisis. Based on the review findings, we argued that Aboriginal communities are best positioned to identify and understand the antecedents of youth self-harm, suicide ideation and suicide, and to take the lead in the development of more effective mental health preventive strategies and public policies within their communities.

Psychiatric research in the Northern Finland Birth Cohort 1986 - a systematic review

The Northern Finland Birth Cohort 1986 is a large population-based birth cohort, which aims to promote health and wellbeing of the population. In this paper, we systematically review the psychiatric research performed in the cohort until today, i.e. at the age of 32 years of the cohort (2018). We conducted a systematic literature search using the databases of PubMed and Scopus and complemented it with a manual search. We found a total of 94 articles, which were classified as examining ADHD, emotional and behavioural problems, psychosis risk or other studies relating to psychiatric subjects. The articles are mainly based on two large comprehensive follow-up studies of the cohort and several substudies. The studies have often used also nationwide register data. The studies have found several early predictors for the aforementioned psychiatric outcomes, such as problems at pregnancy and birth, family factors in childhood, physical inactivity and substance use in adolescence. There are also novel findings relating to brain imaging and cognition, for instance regarding familial risk of psychosis in relation to resting state functional MRI. The Northern Finland Birth Cohort 1986 has been utilised frequently in psychiatric research and future data collections are likely to lead to new scientifically important findings.

Demographic profile, Oral Health Impact Profile and Dental Anxiety Scale in patients with chronic periodontitis: a case-control study

OBJECTIVES

To examine whether dental anxiety (DA) and oral health-related quality of life (OHRQoL) differ between persons with and those without chronic periodontitis.

METHODS

One-hundred patients with chronic periodontitis and 50 age- and- sex-matched controls were included. Data were collected on the following: demographics; smoking habits; Numerical Rating Scale (NRS) for dental pain assessment; Corah's Dental Anxiety Scale (DAS); Oral Health Impact Profile 14 (OHIP-14); Decayed, Missing and Filled Teeth (DMFT) index; Plaque Index (PI); probing depth (PD); bleeding on probing (BOP); and radiographic bone loss.

RESULTS

Patients with chronic periodontitis exhibited a significantly higher percentage of high anxiety and phobia compared with subjects in the control group. Furthermore, patients with chronic periodontitis were statistically significantly more likely to consider themselves as suffering from dental anxiety (68.7% vs. 14.3%, P < 0.001) as well as more likely to have fear of receiving dental injections, hearing the dental drill noise and feeling a foreign object in the mouth. Patients with chronic periodontitis exhibited worse OHIP-14 global scores as well as worse scores in the following individual domains: functional limitation (P = 0.005); physical disability (P = 0.003); psychological disability (P = 0.010); social disability (P = 0.011); and handicap (P = 0.012).

CONCLUSIONS

Compared with controls, patients with chronic periodontitis had higher levels of dental anxiety and worse OHRQoL. It is important to consider dental anxiety and OHRQoL assessment as an integral component of the evaluation of patients with chronic periodontitis. Communication between dental and behavioral health professionals is needed to implement a multidisciplinary team approach involving behavioural and psychological interventions.

Association of stress, depression, and suicidal ideation with subjective oral health status and oral functions in Korean adults aged 35 years or more

Background

Oral health greatly affects well-being throughout the different stages of life from childhood to late adulthood. Loss of teeth due to poor oral health hinders mastication, leading to poor nutrition absorption, and affects pronunciation and aesthetics, leading to interpersonal difficulties. As social activities become limited, a sense of isolation and loneliness, stress, and depression grows while happiness decreases. This study aimed to examine the association of stress, depression, and suicidal ideation with oral health status and oral functions in a large nationwide sample of Korean adults aged 35 years or more.

Methods

The sample comprised 15,716 adults, selected using a rolling survey sampling method and data were extracted from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES) (2010–2012). Participants were interviewed about their self-evaluation of health including oral health status and mental health, such as stress, depression, and suicidal ideation. Data from 11,347 adults were finally selected after excluding participants with missing answers. The dependent variables were stress, depression, and suicidal ideation. The independent variables were gender, age, household income, education, smoking, drinking, oral health perception, chewing, and speaking. Complex samples logistic regression analyses were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs).

Results

Participants met the criteria for stress (25.4%), depression (13.0%), and suicidal ideation (13.9%). Subjective oral health status was not significantly associated with stress, depression, and suicidal ideation. However, the presence of very uncomfortable chewing problems was significantly associated with stress (OR = 2.294, 95% CI = 1.41, 3.72), depression (OR = 3.232, 95% CI = 1.97, 5.31), and suicidal ideation (OR = 2.727, 95% CI = 1.58, 4.72). The presence of very uncomfortable speaking problems was significantly associated with stress (OR = 1.592, 95% CI = 1.13, 2.24) but not significantly associated with depression and suicidal ideation.

Conclusions

Oral functional problems including chewing and speaking difficulties can be associated with mental health. It is necessary to develop oral health promotion programs for adults and help them maintain a good quality of life and mental health.

Socio-economic development and emotion-health connection revisited: a multilevel modeling analysis using data from 162 counties in China

Background

Substantial research has shown that emotions play a critical role in physical health. However, most of these studies were conducted in industrialized countries, and it is still an open question whether the emotion-health connection is a “first-world problem”.

Methods

In the current study, we examined socio-economic development’s influence on emotion-health connection by performing multilevel-modeling analysis in a dataset of 33,600 individuals from 162 counties in China.

Results

Results showed that both positive emotions and negative emotions predicted level of physical health and regional Gross Domestic Product Per Capita (GDPPC) had some impact on the association between emotion and health through accessibility of medical resources and educational status. But these impacts were suppressed, and the total effects of GDPPC on emotion-health connections were not significant.

Conclusions

These results support the universality of emotion-health connection across levels of GDPPC and provide new insight into how socio-economic development might affect these connections.

Racism as a Determinant of Health: A Systematic Review and Meta-Analysis

Despite a growing body of epidemiological evidence in recent years documenting the health impacts of racism, the cumulative evidence base has yet to be synthesized in a comprehensive meta-analysis focused specifically on racism as a determinant of health. This meta-analysis reviewed the literature focusing on the relationship between reported racism and mental and physical health outcomes. Data from 293 studies reported in 333 articles published between 1983 and 2013, and conducted predominately in the U.S., were analysed using random effects models and mean weighted effect sizes. Racism was associated with poorer mental health (negative mental health: r = -.23, 95% CI [-.24,-.21], k = 227; positive mental health: r = -.13, 95% CI [-.16,-.10], k = 113), including depression, anxiety, psychological stress and various other outcomes. Racism was also associated with poorer general health (r = -.13 (95% CI [-.18,-.09], k = 30), and poorer physical health (r = -.09, 95% CI [-.12,-.06], k = 50). Moderation effects were found for some outcomes with regard to study and exposure characteristics. Effect sizes of racism on mental health were stronger in cross-sectional compared with longitudinal data and in non-representative samples compared with representative samples. Age, sex, birthplace and education level did not moderate the effects of racism on health. Ethnicity significantly moderated the effect of racism on negative mental health and physical health: the association between racism and negative mental health was significantly stronger for Asian American and Latino(a) American participants compared with African American participants, and the association between racism and physical health was significantly stronger for Latino(a) American participants compared with African American participants.

The association of depression and anxiety with dental caries and periodontal disease among Finnish adults

OBJECTIVE

To explore the association of depression and anxiety with two oral health outcomes, dental caries and periodontal disease and assess possible mediators for any of the associations.

METHODS

Secondary analysis of the Finnish Health 2000 Survey. Depression was assessed with Beck's Depression Inventory and anxiety with Composite International Diagnostic Interview. Number of decayed teeth included carious lesions reaching dentine; periodontal disease was number of teeth with periodontal pockets of 4 mm or deeper. Third molars were excluded. The association of mental disorders and oral health was tested in regression models adjusted for confounders and potential mediators.

RESULTS

Depression was associated with number of decayed teeth only among 35- to 54-year-olds. The association between anxiety and the number of decayed teeth was not statistically significant. Depression and periodontal pocketing were not significantly associated.

CONCLUSION

Depression was significantly associated with number of decayed teeth only among participants aged 35-54 old and not with other age groups. Neither depression nor anxiety was significantly related to periodontal disease.
