Self-reported data validity for assessment of systemic and oral health as risk for dependency in old age: a cohort profile of elderly individuals in mid Sweden

Purpose

The Mid Sweden Cohort (MSC) was established to investigate self-perceived oral and general health among two groups of aging individuals in two counties (Örebro and Östergötland) in Sweden. For internal and external data validation, we linked collected data on health status, behavior, sociodemographic circumstances, and dependency with national register data from Statistics Sweden and compared non-respondents and those lost to follow-up to respondents.

Participants

MSC is based on a longitudinal multiwave study of aging men and women who answered a cross-sectional questionnaire from MSC: (1) the 1992 cohort including participants aged 50 years in 1992 and (2) the 2007 cohort including participants aged 75 years in 2007. After the baseline surveys, data collection was conducted every 5 years, with the latest wave from 2017 included in our validation. Between 1992 and 2017, 8,879 participants were included in cohort 1, while 5,191 individuals were included in cohort 2 between 2007 and 2017.

Results

After linking self-reported data with national register-based data and analyzing loss to follow-up and non-response numbers, we found that, besides age, factors such as being male, having immigrant status, lower income and education level, being single, and being in poor health were predictors of non-response and loss to follow-up, aligning with the findings of other studies. Based on our results, we conclude the MSC is reliable for further research, provided the observed bias is taken into account.

Future plans

Using the MSC, we aim to analyze self-reported oral health changes as a predictor of dependency in the elderly and track oral health status over time. Furthermore, we plan to link data with register-based clinical oral health records. We also intend to add the 2022 wave data and future waves into the existing dataset.

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.

Satisfaction with dental care and life-course predictors: A 20-year prospective study of a Swedish 1942 birth cohort?

OBJECTIVES

The aim was to assess the impact of care experience, health factors and socioeconomic factors on satisfaction with dental care across time and to assess the stability or change in levels of self-reported satisfaction with dental care in individuals as they progress from middle age to early old age.

MATERIALS AND METHODS

The present work is based on five separate data collections from a cohort study with 3585 individuals responding in all years of the survey. Data collection was conducted in 1992 when the subjects were 50 years of age and again 5, 10, 15 and 20 years later. Absolute stability in satisfaction with dental care was assessed by calculating the proportion of individuals who maintained their position in the same category from one survey period to another. Changes across time were tested using Cochran's Q test. Satisfaction with dental care across the 20-year survey period was modeled using the generalized estimating equation (GEE).

RESULTS AND CONCLUSION

The result showed that 85% of women and 83% of men remained satisfied with dental care. Binomial GEE revealed no statistical significant change in satisfaction with dental care between 1992-2012. In sum, this study has shown that this age group, born in 1942, was stably satisfied with dental care between age 50 and age 70, despite all changes during this time period. Females are more satisfied than men and the most important factors are the experience of attention during the last visit, satisfaction with dental appearance and good chewing capability.

Does different wording of a global oral health question provide different results?

OBJECTIVE

Focusing on 70-year-old adults in Sweden and guided by the conceptual framework of International Classification of Impairments, Disabilities and Handicaps (ICIDH), the purpose of this study was to examine the extent to which socio-demographic characteristics, self-reported oral disease and social/psychological/physical oral health outcome variables are associated with two global measures of self-assessed satisfaction with oral health in Swedish 70-year-olds and if there is a degree of discordance between these global questions.

BACKGROUND

It has become an important task to create a simple way to measure self-perceived oral health. In these attempts to find practical ways to measure health, the 'global oral health question' is a possible tool to measure self-rated oral health, but there is limited knowledge about how important the wording of this question is.

MATERIALS AND METHODS

In 2012, a questionnaire was mailed to all persons born in 1942 in two Swedish counties, Örebro (T) and Östergötland (E). The total population of 70-year-olds amounted to 7889. Bivariate analyses were conducted by cross-tabulation and Chi-square statistics. Multivariate analyses were conducted using binary multiple logistic regression.

RESULTS

The two global oral health question of 70-year-olds in Sweden was mainly explained by the number of teeth (OR=5.6 and 5.2), chewing capacity (OR=6.9 and 4.2), satisfaction with dental appearance (OR=19.8 and 17.3) and Oral Impact on Daily Performance (OIDP) (OR=3.5 and 3.9).

CONCLUSION

Regardless of the wording, it seems that the concept of a global oral health question has the same main determinants.

Social inequality in oral health-related quality-of-life, OHRQoL, at early older age: evidence from a prospective cohort study

OBJECTIVES

This study aimed to assess the long-term effect of socio-behavioral characteristics on oral impacts on daily performances (OIDP) at age 65 and the influence on OIDP at age 65 of changes in socio-behavioral characteristics between age 50 and 65.

METHODS

In 1992, all 50-year-olds in two counties of Sweden were invited to participate in a longitudinal survey. A total of 6346 responded and, of those, 4143 completed follow-ups at ages 55, 60 and 65 years.

RESULTS

At age 65, 26.9% had oral impacts. Subjects being immigrants, being unmarried, reporting economic barriers, bad general health, bad quality dental care, less than annual dental attendance, limited social network and smoking at age 50 experienced oral impacts at age 65 more frequently than their counterparts in the opposite groups. Compared to the stable advantaged groups, stable disadvantaged groups regarding marital status, health status, smoking and reported quality of care had increased ORs for oral impacts. Compared to the stable advantaged groups, those who experienced deterioration with respect to health status, dental attendance and quality of oral health care and those who quitted smoking had increased ORs for oral impacts.

CONCLUSIONS

Disadvantaged socio-behavioral condition at age 50 had a long lasting detrimental effect on OHRQoL at age 65. Deterioration in socio-behavioral circumstances was associated with increased oral impacts. Early protection against the effect of socio-behavioral adversity by imposing economic barriers, ensure provision of high quality care and by promotion of healthy lifestyles seems to have the potential to reduce oral impacts at older ages.
