Health behaviours and quality of life in independently living South Australians aged 75 years or older

Correlates of poor oral health related quality of life in a cohort of people who use methamphetamine in Australia

OBJECTIVES

Methamphetamine use impacts oral health, but little is known about its impacts on oral health related quality of life (OHRQoL). In this study we examined OHRQoL in a cohort of people who use methamphetamine and assessed associations with sociodemographic, behavioural, psychosocial and dental service utilisation correlates. A secondary aim was to examine the relationship between methamphetamine route of administration and OHRQoL, to test whether smoking the drug is associated with reduced OHRQoL.

METHODS

Cross-sectional analysis was performed, using data from VMAX, a cohort of people who use methamphetamine at least monthly in Victoria, Australia (n = 194). Utilising the oral health impact profile (OHIP-14), we assessed three OHRQoL outcomes: OHIP-14 prevalence, OHIP-14 extent and OHIP-14 severity. Regression analyses examined associations between independent variables and the three OHIP-14 outcome measures.

RESULTS

A significant segment of the cohort (35%) reported poor OHRQoL. Overall, no statistically significant association was detected between methamphetamine route of administration and the three OHIP-14 outcomes. Participants living in rural areas, with moderate-to-severe self-reported depression and with methamphetamine dependence had significantly worse OHRQoL levels, which persisted after adjusting for other covariates.

CONCLUSION

Overall, VMAX cohort participants reported reduced OHRQoL levels. Our findings highlight the need for upstream interventions to improve the OHRQoL of people who use methamphetamine, with specific focus on those living in rural locations. Further research on the links between OHRQoL and mental health among people who use methamphetamine is required.

Indicators and Instruments to Assess Components of Disability in Community-Dwelling Older Adults: A Systematic Review

The epidemiological demands of aging point to the need for characterizing older adults regarding health and disability. This systematic review aims to summarize the indicators (instruments) identifying different components of disability as a result of aging exposition in community-dwelling older adults, considering the International Classification of Functioning, Disability, and Health framework. Taking the PRISMA 2020 recommendations as a reference, studies with community-dwelling older adults, reporting the development and/or age disability modifications were included. Two reviewers analyzed the observational studies searched in the MEDLINE, CINAHL, Web of Science, Scopus, and Embase databases. Of the 137 potentially eligible studies, 49 were included in this review. Several indicators (instruments) demonstrated older adults' disabilities according to the different domains of the ICF. Objective measures assessed Body Structures, Body Functions, and Environmental Factors and included handgrip strength (dynamometry, n = 8), cognitive function (Mini-Mental State examination, n = 7), gait speed (walk test, n = 6), and endurance (Chair stand-test, n = 4). Self-reported measures assessed Activities and Participation, but not the Body Structures, and included the basic and instrumental activities of daily living (ADL) (the Katz Index of ADL, n = 4 studies, the Lawton and Brody Instrumental ADL, n = 4 studies). The summary of the measures gathered can guide researchers and health professionals to select indicators (instruments) to assess and monitor older adults' disabilities resulting from aging exposition, to support the development of new wearables, and to provide improvements to the existing ones, allowing the tailored assessment of different health and disability dimensions.

The association between depression and oral health related quality of life in people who inject drugs

BACKGROUND AND AIMS

Oral health related quality of life (OHRQoL) is known to be reduced in disadvantaged populations, including people who inject drugs. Mental health issues, such as depression are also commonly reported. In this study we examined the association between depression and OHRQoL.

METHODS

Cross-sectional analysis survey data was collected from the Melbourne Injecting Drug User Cohort Study (SuperMIX) of people who inject drugs (N = 982). Three measures derived from the Oral Health Impact Profile (OHIP-14) were used to assess OHRQoL: Prevalence (reporting one or more dental issue "Very often" or "Fairly often" in the previous year), Extent (number of items reported either "Very often" or "Fairly often") and Severity (summary score of all ordinal responses). Regression analyses assessed the association between depression, indexed as scoring above 10 on the Patient Health Questionnaire (PHQ-9), and OHIP-14 measures, adjusted for sociodemographic, drug use and dental service utilisation variables.

RESULTS

Overall, participants had low levels of OHRQoL, indexed through OHIP-14 scores (46% exhibiting prevalence, mean extent of 2.35 and mean severity of 12.72). Depression was associated with increases in all OHIP-14 measures, after adjustment for potential confounders.

CONCLUSIONS

We found a significant association between depression and poor OHRQoL in this sample of people who inject drugs. Further research using a longitudinal frame is needed to determine the direction of this relationship. Interventions to improve oral health of people who inject drugs are urgently needed, and these may benefit mental health outcomes for people who inject drugs.

Predictors for oral and general health outcomes and quality of life among older people attending general practice clinics in South Australia

BACKGROUND

As the proportion and number of older people in Australia continue to grow, innovative means to tackle primary care and prevention are necessary to combat the individual, social and economic challenges of non-communicable diseases.

OBJECTIVE

To assess risk factors (or predictors) for oral and general health outcomes and quality of life of older people (75+ years.) attending general practice (GP) clinics in South Australia.

METHODS

Data were collected from older people attending 48 GP clinics in metropolitan South Australia. Age, sex, education, living arrangement, material standards, chronic conditions and nutrition were assessed as risk factors. Global self-rated oral and general health and quality of life (OHIP Severity and EQ-5D Utility) were included as outcome measures.

RESULTS

A total of 459 participants completed the study; response rate was 78%. In the adjusted models, high satisfaction with material standards and good nutritional health were positively associated with all four oral and general health measures. Sex (β = -0.08), age (β = -0.09) and number of chronic conditions (β = -0.12) were negatively associated with EQ-5D, while living arrangement (β = 0.07) was positively associated. Further, having four or more chronic conditions (RR:1.47) was significantly associated with self-rated general health.

CONCLUSION

Satisfaction with material standards and nutritional risk were consistent predictors for oral and general health outcomes and quality of life of older people visiting GP clinics.

Oral health impacts among Australian adults in the National Study of Adult Oral Health (NSAOH) 2017-18

BACKGROUND

This paper examines oral health impacts of toothache experience, self-rated oral health (SROH), being uncomfortable with dental appearance, and avoiding foods in the Australian adult population.

METHODS

The explanatory variables include age, sex, region, income, area-based SES, dental insurance and visiting pattern. The data were collected in the interview in NSAOH 2017-18.

RESULTS

There were lower percentages with: toothache in the highest (14.8%) than middle (21.2%) and lower income tertiles (25.2%); fair/poor SROH in the highest (15.8%) than middle (24.1%) and lower tertiles (34.8%); uncomfortable with appearance in the highest (29.1%) than middle (35.3%) and lower tertiles (42.2%); and food avoidance in the higher (15.3%) than middle (22.9%) and lower tertiles (34.4%). There were higher percentages with: toothache in the unfavourable (32.2%) than intermediate (23.1%) and favourable (11.7%) visiting groups; fair/poor SROH in the unfavourable (44.0%) than intermediate (27.4%) or favourable (10.2%) groups; being uncomfortable about appearance in the unfavourable (47.6%) than intermediate (39.5%) or favourable (25.8%) groups; and avoiding foods in the unfavourable (34.8%) than intermediate (26.0%) or favourable (14.5%) groups.

CONCLUSIONS

Socioeconomic status and dental visiting were associated with oral health impacts. Oral health impacts were worse for those with lower income and unfavourable visiting patterns.

A Review of the Development and Application of Generic Preference-Based Instruments with the Older Population

Older people (aged 65 years and over) are the fastest growing age cohort in the majority of developed countries, and the proportion of individuals defined as the oldest old (aged 80 years and over) living with physical frailty and cognitive impairment is rising. These population changes put increasing pressure on health and aged care services, thus it is important to assess the cost effectiveness of interventions targeted for older people across health and aged care sectors to identify interventions with the strongest capacity to enhance older peoples' quality of life and provide value for money. Cost-utility analysis (CUA) is a form of economic evaluation that typically uses preference-based instruments to measure and value health-related quality of life for the calculation of quality-adjusted life-years (QALYS) to enable comparisons of the cost effectiveness of different interventions. A variety of generic preference-based instruments have been used to measure older people's quality of life, including the Adult Social Care Outcomes Toolkit (ASCOT); Health Utility Index Mark 2 (HUI2); Health Utility Index Mark 3 (HUI3); Short-Form-6 Dimensions (SF-6D); Assessment of Quality of Life-6 dimensions (AQoL-6D); Assessment of Quality of Life-8 dimensions (AQoL-8D); Quality of Wellbeing Scale-Self-Administered (QWB-SA); 15 Dimensions (15D); EuroQol-5 dimensions (EQ-5D); and an older person specific preference-based instrument-the Investigating Choice Experiments Capability Measure for older people (ICECAP-O). This article reviews the development and application of these instruments within the older population and discusses the issues surrounding their use with this population. Areas for further research relating to the development and application of generic preference-based instruments with populations of older people are also highlighted.

Are Edentulousness, Oral Health Problems and Poor Health-Related Quality of Life Associated with Malnutrition in Community-Dwelling Elderly (Aged 75 Years and Over)? A Cross-Sectional Study

As the population ages, the risk of becoming malnourished increases. Research has shown that poor oral health can be a risk factor for malnutrition in institutionalized elderly. However, it remains unclear whether oral health problems, edentulousness and health-related quality of life also pose a risk for malnutrition in community-dwelling older adults. In this cross-sectional observational study, 1325 community-living elderly (≥75 years) were asked to complete questionnaires regarding nutritional status, oral status (edentulous, remaining teeth, or implant-supported overdentures), oral health problems, health-related quality of life (HRQoL), frailty, activities of daily living (ADL) and complexity of care needs. Univariate and multivariate logistic regression analyses were performed with nutritional status as dependent variable. Of the respondents, 51% (n = 521) were edentulous, 38.8% (n = 397) had remaining teeth and 10.2% (n = 104) had an implant-supported overdenture. Elderly with complex care needs were malnourished most frequently, followed by frail and robust elderly (10%, 4.5% and 2.9%, respectively). Malnourished elderly reported more frequent problems with chewing and speech when compared with well-nourished elderly (univariate analysis). However, multivariate analysis did not show an association between malnutrition and oral health problems and edentulousness, although HRQoL was associated with malnutrition (odds ratio (OR) 0.972, confidence interval (CI) 0.951–0.955). Based on the results of this cross-sectional study, it can be concluded that poor HRQoL is significantly associated with malnutrition; however, edentulousness and oral health problems are not.
