Biological costs and benefits of social relationships for men and women in adulthood: The role of partner, family and friends.

Despite numerous studies on social relationships and health, the empirical focus has often been on middle-aged or older adults, even though young adulthood is a period of considerable change in social networks. We investigated whether the associations between social relationships and allostatic load, a multisystem physiological dysregulation index that reflects chronic stress responses, vary by type of relationship and stages of the lifecourse. Relationships with spouse/partner, immediate family and friends were assessed in terms of emotional support and social strain. Poisson regression models on multiple imputed data sets from waves 2-3 (2010-2012) of the UK Household Longitudinal Study (N = 10,380) were estimated. Social strain, particularly from partners and immediate family, appeared to elicit greater stress related dysregulation during early adulthood (age 21-34 years), corresponding to a predicted difference in the allostatic load index (range 0-12) between high and low strained relationships of 1.1 (95% CI: 0.5-1.6) among young women and 0.6 (95% CI: -0.04 to 1.2) among young men. There was little evidence of an association between allostatic load and any of the social relationships among older men and women. Models of social relationships over the lifecourse need to take account of how stressful social relationships become biologically embedded in early adulthood.

Social Capital and Oral Health Among Adults 50 Years and Older: Results From the English Longitudinal Study of Ageing.

OBJECTIVES: This study examines the differential associations of structural and functional social capital with objective and subjective measures of oral health, and the interactions between social capital and other sociodemographic and health factors. METHODS: Secondary analysis of data on 8552 adults 50 years and older from the third wave (2006-2007) of the English Longitudinal Study of Ageing was conducted. Oral health outcomes were self-rated oral health, edentulousness (having no natural teeth), and Oral Impacts on Daily Performances. Structural social capital was measured by membership of social organizations and volunteering. Functional social capital was measured by the number of close ties and perceived emotional social support. Logistic regression models were sequentially adjusted for demographic, socioeconomic, health-related factors, and smoking status. RESULTS: Structural social capital was primarily associated with edentulousness. Not being a member of any organization was associated with higher odds of being edentate (odds ratio [OR] = 1.77, 95% confidence interval [CI] = 1.43-2.16). Functional social capital was associated with self-rated oral health and oral impacts. Low social support was associated with poor self-rated oral health (OR = 1.41, 95% CI = 1.16-1.72) and Oral Impacts on Daily Performances (OR = 1.69, 95% CI = 1.27-2.24). CONCLUSIONS: The association of structural social capital with edentulousness may reflect health selection effects. The availability of a supportive social network seems to be the aspect of social capital most strongly associated with oral health.

Home modifications and disability outcomes: A longitudinal study of older adults living in England.

Background: There is limited evidence on the protective effect of housing modifications on disability outcomes among older adults. We examined whether external and internal housing modifications reduce the risk of a range of disability outcomes among older adults living in England. Methods: We analysed adults aged 60 and over from the English Longitudinal Study of Ageing, initially recruited in 2002/03. The longitudinal sample consisted of 32,126 repeated observations from 10,459 individuals across 6 waves with an average follow-up of 11·3 years. Participants were asked if their homes had external (widened doorways, ramps, automatic doors, parking and lift) and internal (rails, bathroom/kitchen modifications, chair lift) housing modifications. Mobility impairment was measured through reported difficulties in 10 activities including walking, climbing, getting up, reaching and lifting. Five disability outcomes were analysed (falls in the previous two years, pain, poor self-rated health, no social activities, and moving home within next two years) using two-way fixed effect models, controlling for key risk factors for disability. Findings: Greater mobility impairments increased the probability of falls, pain and poor self-rated health although this effect was significantly moderated by external housing modifications. Among older adults with severe mobility impairments, external housing modifications reduced the probability of falls by 3% (1%-6%), pain by 6% (4%-8%), and poor health by 4% (2%-5%). Moreover, external housing modifications reduced the probability of no social activities by 6% (5%-7%) and moving home by 4% (2%-5%) even among those without any mobility impairments. Internal housing modifications had similar, but less consistent effects on the disability outcomes. Interpretation: There was strong evidence that external housing modifications protected against a range of disability outcomes. Studies on reducing disability in ageing populations need to consider the role of housing modifications as key interventions to promote healthy ageing in place.

The role of workplace accommodations in explaining the disability employment gap in the UK.

There has been limited theoretical and empirical research into the role of workplace accommodations in enabling workers with and without impairments to remain in work. This study used the International Classification of Functioning, Disability and Health (ICF) model to examine (a) whether workplace accommodations enable workers, particularly those with different impairments, to remain economically active; and (b) the predictors of the onset of work accommodations. Data from two waves of a large-scale longitudinal survey of disability in Great Britain, the Life Opportunities Survey (2009-2012) were analysed. 2307 workers with an impairment and 4308 workers without an impairment were followed up for a year. Work accommodations appear to enable workers with impairments to remain economically active, especially those with mental impairments. There was no difference in the employment rates of workers with and without mental impairments who had two or more work accommodations, in contrast to the 10% employment gap between workers with and without mental impairments who did not have any work accommodations. While there was no gender difference in the disability employment gap, barriers to employment related to caregiving were much greater for women compared to men. Moreover, only workers with incident pain impairments were associated with an increase in their work accommodations, not workers with incident mental impairments. Despite the evidence that workers with mental impairments could benefit considerably from workplace accommodations, they are less likely to have their workplace adjusted. The ICF model is particularly useful in analysing the role of work accommodations because it considers a much wider range of factors that are relevant not just to workers with different types of impairments, but are also relevant to the wider group of workers who use workplace accommodations.

Socioeconomic and ethnic inequalities in oral health among children and adolescents living in England, Wales and Northern Ireland.

OBJECTIVES: Although adolescence is a sensitive developmental period in oral health, the social equalization hypothesis that suggests health inequalities attenuate in adolescence has not been examined. This study analyses whether the socioeconomic gap and ethnic disadvantage in oral health among children aged 5 reduces among adolescents aged 15. METHODS: Data from the cross-sectional Children's Dental Health Survey 2013 were analysed, comprising of 8541 children aged 5, 8, 12 and 15 attending schools in England, Wales and Northern Ireland. Oral health indicators included decayed and filled teeth, plaque, gingivitis and periodontal health. Ethnicity was measured using the 2011 UK census ethnic categories. Socioeconomic position was measured by family, school and residential deprivation. Negative binomial and probit regression models estimated the levels of oral health by ethnicity and socioeconomic position, adjusted for demographic and tooth characteristics. RESULTS: The predicted rate of decayed teeth for White British/Irish children aged 5 was 1.54 (95%CI 1.30-1.77). In contrast, the predicted rate for Indian and Pakistani children was about 2-2.5 times higher. At age 15, ethnic differences had reduced considerably. Family deprivation was associated with higher levels of tooth decay among younger children but not among adolescents aged 15. The influence of residential deprivation on the rate of tooth decay and filled teeth was similar among younger and older children. Moreover, inequalities in poor periodontal health by residential deprivation was significantly greater among 15-year-old children compared to younger children. CONCLUSIONS: This study found some evidence of smaller ethnic and family socioeconomic differences in oral health among British adolescents compared to younger children. However, substantial differences in oral health by residential deprivation remain among adolescents. Community levels of deprivation may be particularly important for the health of adolescents.

Retirement and Socioeconomic Differences in Diurnal Cortisol: Longitudinal Evidence From a Cohort of British Civil Servants.

Objectives: Early old age and the period around retirement are associated with a widening in socioeconomic inequalities in health. There are few studies that address the stress-biological factors related to this widening. This study examined whether retirement is associated with more advantageous (steeper) diurnal cortisol profiles, and differences in this association by occupational grade. Method: Data from the 7th (2002-2004), 8th (2006), and 9th (2007-09) phases of the London-based Whitehall II civil servants study were analysed. Thousand hundred and forty three respondents who were employed at phase 8 (mean age 59.9 years) and who had salivary cortisol measured from five samples collected across the day at phases 7 and 9 were analysed. Results: Retirement was associated with steeper diurnal slopes compared to those who remained in work. Employees in the lowest grades had flatter diurnal cortisol slopes compared to those in the highest grades. Low-grade retirees in particular had flatter diurnal slopes compared to high-grade retirees. Discussion: Socioeconomic differences in a biomarker associated with stress increase, rather than decrease, around the retirement period. These biological differences associated with transitions into retirement for different occupational groups may partly explain the pattern of widening social inequalities in health in early old age.

Oral Health-A Neglected Aspect of Subjective Well-Being in Later Life.

Objectives: This study examined whether oral health is a neglected aspect of subjective well-being (SWB) among older adults. The key research question was whether deterioration in oral health among dentate older adults living in England was associated with decreases in SWB, using measures of eudemonic, evaluative, and affective dimensions of well-being. Methods: This secondary analysis used data from the third (2006-2007) and fifth (2010-2011) waves of respondents aged 50 and older from the English Longitudinal Study of Ageing (ELSA). We fitted multivariable regression models to examine the effects of changes in oral impacts on daily life and edentulism (complete tooth loss) on SWB (quality of life, life satisfaction, and depressive symptomatology). Results: A worsening in both oral health measures was associated with an increase in depressive symptoms even after adjusting for time-varying confounders including declining health, activities of daily living, and reduced social support. Becoming edentate was also associated with decreases in quality of life and life satisfaction. Discussion: A deterioration in oral health and oral health-related quality of life increases the risk of depressive symptoms among older adults and highlights the importance of oral health as a determinant of subjective well-being in later life.

Does public transport use prevent declines in walking speed among older adults living in England? A prospective cohort study.

OBJECTIVES: Although there is some evidence that public transport use confers public health benefits, the evidence is limited by cross-sectional study designs and health-related confounding factors. This study examines the effect of public transport use on changes in walking speed among older adults living in England, comparing frequent users of public transport to their peers who did not use public transport because of structural barriers (poor public transport infrastructure) or through choice. DESIGN: Prospective cohort study. SETTING: England, UK. PARTICIPANTS: Older adults aged ≥60 years eligible for the walking speed test. 6246 individuals at wave 2 (2004-2005); 5909 individuals at wave 3 (2006-2007); 7321 individuals at wave 4 (2008-2009); 7535 individuals at wave 5 (2010-2011) and 7664 individuals at wave 6 (2012-2013) of the English Longitudinal Study of Ageing. MAIN OUTCOME MEASURE: The walking speed was estimated from the time taken to walk 2.4 m. Fixed effects models and growth curve models were used to examine the associations between public transport use and walking speed. RESULTS: Older adults who did not use public transport through choice or because of structural reasons had slower walking speeds (-0.02 m/s (95% CI -0.03 to -0.003) and -0.02 m/s (95% CI -0.03 to -0.01), respectively) and took an extra 0.07 s to walk 2.4 m compared with their peers who used public transport frequently. The age-related trajectories of decline in walking speed were slower for frequent users of public transport compared with non-users. CONCLUSIONS: Frequent use of public transport may prevent age-related decline in physical capability by promoting physical activity and lower limb muscle strength among older adults. The association between public transport use and slower decline in walking speed among older adults is unlikely to be confounded by health-related selection factors. Improving access to good quality public transport could improve the health of older adults.

Oral health-related quality of life and loneliness among older adults.

Loneliness is a serious concern in aging populations. The key risk factors include poor health, depression, poor material circumstances, and low social participation and social support. Oral disease and tooth loss have a significant negative impact on the quality of life and well-being of older adults. However, there is a lack of studies relating oral health to loneliness. This study investigated the association between oral health-related quality of life (through the use of the oral impact on daily performances-OIDP-measure) and loneliness amongst older adults living in England. Data from respondents aged 50 and older from the third (2006-2007) and fifth (2010-2011) waves of the English Longitudinal Study of Ageing were analyzed. In the cross-sectional logistic regression model that adjusted for socio-demographic, socio-economic, health, and psychosocial factors, the odds of loneliness were 1.48 (1.16-1.88; p < 0.01) higher amongst those who reported at least one oral impact compared to those with no oral impact. Similarly, in the fully adjusted longitudinal model, respondents who reported an incident oral impact were 1.56 times (1.09-2.25; p < 0.05) more likely to become lonely. The association between oral health-related quality of life and loneliness was attenuated after adjusting for depressive symptoms, low social participation, and social support. Oral health-related quality of life was identified as an independent risk factor for loneliness amongst older adults. Maintaining good oral health in older age may be a protective factor against loneliness.

Tooth loss associated with physical and cognitive decline in older adults.

OBJECTIVES: To examine the effect of total tooth loss (edentulousness) on decline in physical and cognitive functioning over 10 years in older adults in England. DESIGN: Secondary data analysis. SETTING: English Longitudinal Study of Ageing, a national prospective cohort study of community-dwelling people aged 50 and older. PARTICIPANTS: Individuals aged 60 and older (N = 3,166). MEASUREMENTS: Cognitive function (memory) was measured using a 10-word recall test. Physical function was assessed using gait speed (m/s). Generalized estimating equations were used to model associations between baseline edentulousness and six repeated measurements of gait speed and memory from 2002-03 to 2012-13. Models were sequentially adjusted for time, demographic characteristics, socioeconomic status, comorbidities, health behaviors, depressive symptoms, and anthropometric measurements and mutually adjusted for gait speed or memory. RESULTS: Edentulous participants recalled 0.88 fewer words and were 0.09 m/s slower than dentate participants after adjusting for time and demographics. Only the latter association remained significant after full adjustment, with edentulous participants being 0.02 m/s slower than dentate participants. In age-stratified analyses, baseline edentulousness was associated with both outcomes in fully adjusted models in participants aged 60 to 74 but not in those aged 75 and older. Supplementary analysis indicated significant associations between baseline edentulousness and 4-year change in gait speed and memory in participants aged 60 to 74; the former was fully explained in the fully adjusted model and the latter after adjusting for socioeconomic status. CONCLUSION: Total tooth loss was independently associated with physical and cognitive decline in older adults in England. Tooth loss is a potential early marker of decline in older age.

Is Social Capital a Determinant of Oral Health among Older Adults? Findings from the English Longitudinal Study of Ageing.

There are a number of studies linking social capital to oral health among older adults, although the evidence base mainly relies on cross-sectional study designs. The possibility of reverse causality is seldom discussed, even though oral health problems could potentially lead to lower social participation. Furthermore, few studies clearly distinguish between the effects of different dimensions of social capital on oral health. The objective of the study was to examine the longitudinal associations between individual social capital and oral health among older adults. We analyzed longitudinal data from the 3rd and 5th waves of the English Longitudinal Study of Ageing (ELSA). Structural social capital was operationalized using measures of social participation, and volunteering. Number of close ties and perceived emotional support comprised the functional dimension of social capital. Oral health measures were having no natural teeth (edentate vs. dentate), self-rated oral health and oral health-related quality of life. Time-lag and autoregressive models were used to explore the longitudinal associations between social capital and oral health. We imputed all missing data, using multivariate imputation by chained equations. We found evidence of bi-directional longitudinal associations between self-rated oral health, volunteering and functional social capital. Functional social capital was a strong predictor of change in oral health-related quality of life - the adjusted odds ratio of reporting poor oral health-related quality of life was 1.75 (1.33-2.30) for older adults with low vs. high social support. However in the reverse direction, poor oral health-related quality of life was not associated with changes in social capital. This suggests that oral health may not be a determinant of social capital. In conclusion, social capital may be a determinant of subjective oral health among older adults rather than edentulousness, despite many cross-sectional studies on the latter.

Social capital: theory, evidence, and implications for oral health.

In the last two decades, there has been increasing application of the concept of social capital in various fields of public health, including oral health. However, social capital is a contested concept with debates on its definition, measurement, and application. This study provides an overview of the concept of social capital, highlights the various pathways linking social capital to health, and discusses the potential implication of this concept for health policy. An extensive and diverse international literature has examined the relationship between social capital and a range of general health outcomes across the life course. A more limited but expanding literature has also demonstrated the potential influence of social capital on oral health. Much of the evidence in relation to oral health is limited by methodological shortcomings mainly related to the measurement of social capital, cross-sectional study designs, and inadequate controls for confounding factors. Further research using stronger methodological designs should explore the role of social capital in oral health and assess its potential application in the development of oral health improvement interventions.

Fluoretos tópicos: como e quando utilizá-los / Topical fluorides: when and how use then

Os resultados positivos obtidos mediante o uso de fluoretos no controle da doença cárie são indiscutiveis e reconhecidos cientificamente. A partir da década de 80, um declínio de lesões cariosas começou a ser relatado em países desenvolvidos. Dez anos depois, esse fato passou também a ser notado em países emergentes como no Brasil, e tem sido sugerido que dentofrícios fluoretados tiveram papel relevante neste fenômeno. Embora haja consenso da relação existente entre o uso de fluoreto e a redução de lesões cariosas, o reconhecimento de sua ação terapêutica permanece vaga, sendo necessário uma revisão baseada em evidências para direcionar o uso deste composto na prática odontológica. O objetivo do presente trabalho é estabelecer as recomendções do uso tópico de fluoretos em níveis individual, profissional e coletivo, de modo a possibilitar ao profissional a escolha do método mais adequado às necessidades de cada paciente ou grupo de indivíduos.
