Metrological performances of the global chronic morbidity indicator of the Minimum European Health Module and implications for chronic disease prevalence and socioeconomic gradient estimations.

BACKGROUND: Although the global chronic morbidity indicator (GCMI) of the Minimum European Health Module (MEHM) was not specifically designed to monitor chronic disease in the population, it is increasingly used for this purpose in Europe and elsewhere. However, its metrological characteristics have seldom been examined, with various sensitivity issues being raised. The present study investigated the metrological performances of the GCMI and analyzed its implications in terms of prevalence and demographic and socioeconomic gradients of chronic conditions in the population. METHODS: We used data from two large French nationwide representative surveys with cross-sectional and longitudinal data conducted between 2010 and 2021. The surveys used MEHM and collected data on numerous chronic conditions and socioeconomic indicators. Criterion and predictive validity of the GCMI regarding chronic conditions and the resultant socioeconomic gradients were compared with indicators based on reports of individual chronic conditions. RESULTS: GCMI sensitivity to capture chronic conditions varied from <20 to 80% depending on the chronic condition. Number of chronic conditions, gender, age and education were also associated with GCMI endorsement. However, the GCMI was predictive of mortality and activity limitations independently of individual conditions. CONCLUSION: The varying lack of sensitivity depending on the chronic condition and the respondent's sociodemographic status may bias estimates of demographic and socioeconomic gradients compared with indicators based on reports of individual chronic conditions. Differences between GCMI and list-based approaches should be more cautiously considered when monitoring chronic conditions in the population. These approaches should be viewed as complementary rather than contradictory or interchangeable.

Individual and contextual risk factors for mortality in nursing home residents during the first wave of COVID-19 in France: a multilevel analysis of a nationwide cohort study.

BACKGROUND: Mortality amongst nursing home (NH) residents increased by 43% during the first wave of coronavirus disease 2019 (COVID-19). We estimated the 'contextual effect' on mortality, tried to explain it by NH characteristics and identified resident- and NH-level risk factors for mortality. METHODS: The contextual effect was measured for two cohorts of NH residents managed by the general scheme in metropolitan France (RESIDESMS data from 03/01/2020 to 05/31/2020 and 03/01/2019 to 05/31/2019) by the intraclass correlation coefficient (ICC) estimated from mixed-effects logistic regression. RESULTS: Amongst 385,300 residents (5,339 NHs) included in 2020 (median age 89 years, 25% men), 9.1% died, versus 6.7% of 379,926 residents (5,270 NHs) in 2019. In the empty model, the ICC was 9.3% in 2020 and 1.5% in 2019. Only the geographic location partially explained the heterogeneity observed in 2020 (ICC: 6.5% after adjustment). Associations with mortality were stronger in 2020 than in 2019 for male sex and diabetes and weaker for heart disease, chronic respiratory disease and residence <6 months. Mortality was higher in 2020 (15.1%) than 2019 (6.3%) in NHs with at least one death with a mention of COVID-19 and more heterogeneous (ICC: 8.0%) than in the others (mortality: 6.7% in both years; ICC: 1.1%). CONCLUSION: Our results suggest that the COVID-19 crisis had a heterogeneous impact on mortality in NH residents and that geographic location explain a part of the contextual effect, which appears to have had little influence on mortality in NHs not being affected by the virus.

Magnitude, change over time, demographic characteristics and geographic distribution of excess deaths among nursing home residents during the first wave of COVID-19 in France: a nationwide cohort study.

BACKGROUND: The objectives were to assess the excess deaths among Nursing Home (NH) residents during the first wave of the COVID-19 pandemic, to determine their part in the total excess deaths and whether there was a mortality displacement. METHODS: We studied a cohort of 494,753 adults in 6,515 NHs in France exposed to COVID-19 pandemic (from 1 March to 31 May 2020) and compared with the 2014-2019 cohorts using data from the French National Health Data System. The main outcome was death. Excess deaths and standardized mortality ratios (SMRs) were estimated. RESULT: There were 13,505 excess deaths. Mortality increased by 43% (SMR: 1.43). The mortality excess was higher among males than females (SMR: 1.51 and 1.38) and decreased with increasing age (SMRs in females: 1.61 in the 60-74 age group, 1.58 for 75-84, 1.41 for 85-94 and 1.31 for 95 or over; males: SMRs: 1.59 for 60-74, 1.69 for 75-84, 1.47 for 85-94 and 1.41 for 95 or over). No mortality displacement effect was observed up until 30 August 2020. By extrapolating to all NH residents nationally (N = 570,003), we estimated that they accounted for 51% of the general population excess deaths (N = 15,114 out of 29,563). CONCLUSION: NH residents accounted for half of the total excess deaths in France during the first wave of the COVID-19 pandemic. The excess death rate was higher among males than females and among younger than older residents.

Contribution of chronic conditions to gender disparities in health expectancies in Belgium, 2001, 2004 and 2008.

Background: We aimed to investigate the contribution of chronic conditions to gender differences in disability-free life expectancy (DFLE) and life expectancy with disability (LED) in Belgium in 2001, 2004 and 2008. Methods: Data on disability and chronic conditions from participants of the 2001, 2004 and 2008 Health Interview Surveys in Belgium were used to estimate disability prevalence by cause using the attribution method. Disability prevalence was applied to life tables to estimate DFLE and LED using the Sullivan method. Decomposition techniques were used to assess the contribution of mortality and disability and further of causes of death and disability to gender disparities in DFLE and LED. Results: Higher LE, DFLE and LED were observed for women compared with men in all years studied. A decrease in the gender gap in LE (2001: 5.9; 2004: 5.6; 2008: 5.3) was observed in our cross-sectional approach followed by a decrease in gender differences in DFLE (2001: 1.9; 2004: 1.3; 2008: 0.5) and increase in LED (2001: 4.0; 2004: 4.4; 2008: 4.8). The higher LED in women was attributed to their lower mortality due to lung/larynx/trachea cancer, ischaemic heart diseases, and external causes (2001 and 2004) and higher disability prevalence due to musculoskeletal conditions (2008). Higher DFLE was observed in women owing to their lower mortality from lung/larynx/trachea cancer, ischaemic heart diseases, digestive cancer and chronic respiratory diseases. Conclusion: To promote healthy ageing of populations, priority should be given to reduce the LED disadvantage in women by targeting non-fatal diseases, such as musculoskeletal conditions.

Women's excess unhealthy life years: disentangling the unhealthy life years gap.

BACKGROUND: Compared to men, women live longer but have more years with disability. We assessed the contribution of gender differences in mortality and disability, total and by cause, to women's excess unhealthy life years (ULYs). METHODS: We used mortality data for France 2008 from Eurostat, causes of death from the CépiDc-INSERM-database; and disability and chronic conditions data from the French Disability Health Survey 2008-09. ULYs were calculated by the Sullivan method. The contributions of mortality and disability differences to gender differences in ULY were based on decomposition analyses. RESULTS: Life expectancy of French women aged 50 was 36.3 years of which 19.0 were ULYs; life expectancy of men was 30.4 years of which 14.2 were ULYs. Of the 4.8 excess ULYs in women, 4.0 years were due to lower mortality. Of these 4.0 ULYs, 1.8 ULY originated from women's lower mortality from cancer, 0.8 ULY from heart disease and 0.3 ULY from accidents. The remaining 0.8 excess ULY in women were from higher disability prevalence, including higher disability from musculoskeletal diseases (+1.8 ULY) and anxiety-depression (+0.6 ULY) partly offset by lower disability from heart diseases (-0.8 ULY) and accidents (-0.3 ULY). CONCLUSION: Lower mortality and higher disability prevalence contributed to women's longer life expectancy with disability. Women's higher disability prevalence due to non-fatal disabling conditions was partly offset by lower disability from heart disease and accidents. Conditions differentially impact gender differences in ULY, depending on whether they are mainly life-threatening or disabling. The conclusions confirm the health-survival paradox.

Contribution of chronic conditions to disability in men and women in France.

Background: Women report more disability than men perhaps due to gender differences in the prevalence of diseases and/or in their disabling impact. We compare the contribution of chronic diseases to disability in men and women in France, using a disability survey conducted in both private households and institutions, and we also examine the effect of excluding the institutionalized population. Methods: Data comprised 17 549 individuals age 50+, who participated in the 2008-09 French Disability Health Survey including people living in institutions. Disability was defined by limitations in activities people usually do due to health problems (global activity limitation indicator). Additive regression models were fitted separately by gender to estimate the contribution of conditions to disability taking into account multi-morbidity. Results: Musculoskeletal diseases caused most disability for both men (10.1%, CI: 8.1-12.0) and women (16.0%, CI 13.6-18.2). The second contributor for men was heart diseases (5.7%, CI: 4.5-6.9%), and for women anxiety-depression (4.0, CI 3.1-5.0%) closely followed by heart diseases (3.8%, CI 2.9-4.7%). Women's higher contribution of musculoskeletal diseases reflected their higher prevalence and disabling impact; women's higher contribution of anxiety-depression and lower contributions of heart diseases reflected gender differences in prevalence. Excluding the institutionalized population did not change the overall conclusions. Conclusions: The largest contributors to the higher disability of women than men are moderately disabling conditions with a high prevalence. Whereas traditional disabling conditions such as musculoskeletal diseases are more prevalent and disabling in women, fatal diseases such as cardiovascular disease are also important contributors in women and men.

Frailty and Associated Factors among Centenarians in the 5-COOP Countries.

BACKGROUND: The global number of centenarians is still strongly growing and information about the health and healthcare needs of this segment of the population is needed. This study aimed to estimate the prevalence of frailty among centenarians included in a multinational study and to investigate associated factors. METHODS: The 5-COOP study is a cross-sectional survey including 1,253 centenarians in 5 countries (Japan, France, Switzerland, Denmark, and Sweden). Data were collected using a standardized questionnaire during a face-to-face interview (73.3%), telephone interview (14.5%), or by postal questionnaire (12.2%). The 5 dimensions of the frailty phenotype (weight loss, fatigue, weakness, slow walking speed, and low level of physical activity) were assessed by using self-reported data. Factors associated with frailty criteria were investigated by using multivariate regression models. RESULTS: Almost 95% of the participants had at least 1 frailty criterion. The overall prevalence of frailty (3 criteria or more) was 64.7% (from 51.5% in Sweden to 77.6% in Switzerland), and 32.2% of the participants had 4 or 5 criteria. The most frequent criteria were weakness (84.2%), slow walking speed (77.6%), and low level of physical activity (72.5%), followed by fatigue (43.8%) and weight loss (23.8%). Factors associated with frailty included data collection modes, country of residence, gender, living in institution, depression, dementia, disability, falls, and sensory impairments. CONCLUSIONS: This study shows that reaching 100 years of age rarely goes without frailty and sheds light on factors associated with frailty at a very old age.

Potentially inappropriate prescription of antidepressants in old people: characteristics, associated factors, and impact on mortality.

ABSTRACTBackground:The increasing use of antidepressants (ADs) has raised concerns about their inappropriate use in old people. OBJECTIVE: To examine the prevalence of potentially inappropriate prescribing (PIP) of ADs, their associated factors, and their impact on mortality in a sample of old people in France. METHODS: The analysis used data from the SIPAF study, a cross-sectional study consisting of 2,350 people aged ≥ 70 years. Trained nurses interviewed participants at home between 2008 and 2010. Information was collected concerning socio-demographic and health characteristics, including medication use. The study population consisted of the 318 AD users from the SIPAF study (13.5%). PIP of ADs was defined according to national and international criteria. Factors associated with PIP of ADs were assessed using a multivariate logistic regression model. The influence of PIP of ADs on mortality was assessed using a Cox model (median follow-up 2.8 years). RESULTS: Among the SIPAF study, 71% of AD users were female and the mean age was 84 ± 7 years. Selective serotonin reuptake inhibitors (SSRIs) were the most prescribed ADs (19.8%). We found PIP of ADs in 36.8% of the study population, mainly the co-prescription of diuretics with SSRIs (17.6%) and the prescription of tricyclics (12.9%). PIP of ADs was associated with polypharmacy (aOR5-9 drugs 2. 61, 95% CI 1.11-6.16 and aOR≥10 drugs 2.69, 95% CI 1.06-6.87) and comorbidity (aOR3-4 chronic diseases 2.59, 95%CI 1.04-6.44 and aOR≥5 chronic diseases 2.33, 95%CI 0.94-5.79), and increased the risk of mortality during follow-up (aHR 2.30, 95%CI 1.28-4.12). CONCLUSIONS: This study shows that more than one third of AD prescriptions may be inappropriate in old people. PIP of ADs was related to polypharmacy and comorbidity and increased mortality among AD users.

Contribution of chronic conditions to smoking differences in life expectancy with and without disability in Belgium.

Background: Smoking is the leading cause of premature mortality and morbidity. This study aimed at assessing the impact of smoking on life expectancy (LE) and LE with (LED) and without disability (DFLE). We further estimated the contribution of disability and mortality and their causes to differences in LED and DFLE by smoking. Methods: Data on disability, chronic conditions, and smoking from 17 148 participants of the 1997, 2001, 2004 Belgian Health Interview Surveys were used to estimate causes of disability using the attribution method. A 10-year mortality follow-up of survey participants was used. The Sullivan method was applied to estimate LED and DFLE. The contribution of disability and mortality and of causes of disability and death to smoking differences in LED and DFLE was assessed using decomposition methods. Results: Never smokers live longer than daily smokers. DFLE advantage at age 15 of +8.5/+4.3 years (y) in men/women never compared with daily smokers was the result of lower mortality (+6.2y/+3y) and lower disability (2.3y/1.3y). The extra 0.3y/1.6y LED in never smokers was due to lower mortality (+2.6y/+2.9y) and lower disability (-2.3y/-1.3y). Lower mortality from lung/larynx/trachea cancer, chronic respiratory, and ischaemic heart diseases was the main contributor to higher LED and DFLE in never smokers. Lower disability from musculoskeletal conditions in men and chronic respiratory diseases in women increased LED and DFLE in never smokers. Conclusions: Mortality and disability advantage among never smokers contributed to longer DFLE, while mortality advantage contributed to their longer LED.

ICC-dementia (International Centenarian Consortium - dementia): an international consortium to determine the prevalence and incidence of dementia in centenarians across diverse ethnoracial and sociocultural groups.

BACKGROUND: Considerable variability exists in international prevalence and incidence estimates of dementia. The accuracy of estimates of dementia in the oldest-old and the controversial question of whether dementia incidence and prevalence decline at very old age will be crucial for better understanding the dynamics between survival to extreme old age and the occurrence and risk for various types of dementia and comorbidities. International Centenarian Consortium - Dementia (ICC-Dementia) seeks to harmonise centenarian and near-centenarian studies internationally to describe the cognitive and functional profiles of exceptionally old individuals, and ascertain the trajectories of decline and thereby the age-standardised prevalence and incidence of dementia in this population. The primary goal of the ICC-Dementia is to establish a large and thorough heterogeneous sample that has the power to answer epidemiological questions that small, separate studies cannot. A secondary aim is to examine cohort-specific effects and differential survivorship into very old age. We hope to lay the foundation for further investigation into risk and protective factors for dementia and healthy exceptional brain ageing in centenarians across diverse ethnoracial and sociocultural groups. METHODS: Studies focusing on individuals aged ≥95 years (approximately the oldest 1 percentile for men, oldest 5th percentile for women), with a minimum sample of 80 individuals, including assessment of cognition and functional status, are invited to participate. There are currently seventeen member or potential member studies from Asia, Europe, the Americas, and Oceania. Initial attempts at harmonising key variables are in progress. DISCUSSION: General challenges facing large, international consortia like ICC-Dementia include timely and effective communication among member studies, ethical and practical issues relating to human subject studies and data sharing, and the challenges related to data harmonisation. A specific challenge for ICC-Dementia relates to the concept and definition of'abnormal' in this exceptional group of individuals who are rarely free of physical, sensory and/or cognitive impairments.

Decreased Proportion of Dementia-Free Life Expectancy in Hong Kong SAR.

BACKGROUND: Estimations of life expectancies (LE) in health and ill health are important for planning future health care support. This study aimed at quantifying whether an increased LE is accompanied by an increase in the duration of life with dementia (DemLE) in Hong Kong SAR. METHODS: Two parameters from a logistic model were used to fit the overall trend of the weighted prevalence of dementia. Abridged age- and sex-specific life tables and Sullivan's method were used to calculate dementia-free LE (DemFLE) for 1998 and 2013. RESULTS: In 2013, among elderly individuals in Hong Kong aged 65 years, men had lived with dementia for 1.8 years and women for 3.6 years. These values are similar to those for subjects aged ≥85 years, while the proportion of DemLE was much greater at advanced ages. Elderly female individuals tend to experience a greater number of years with dementia than males. CONCLUSION: Our results indicate although LE has increased for all older age groups over time, the increase in DemFLE has not been greater than the gain in LE, suggesting an absolute expansion of the burden of dementia to the community between 1998 and 2013. The results suggest that more caregiving resources and manpower will be needed in the future as the population ages.

Assessing the validity of the Global Activity Limitation Indicator in fourteen European countries.

BACKGROUND: The Global Activity Limitation Indicator (GALI), the measure underlying the European indicator Healthy Life Years (HLY), is widely used to compare population health across countries. However, the comparability of the item has been questioned. This study aims to further validate the GALI in the adult European population. METHODS: Data from the European Health Interview Survey (EHIS), covering 14 European countries and 152,787 individuals, were used to explore how the GALI was associated with other measures of disability and whether the GALI was consistent or reflected different disability situations in different countries. RESULTS: When considering each country separately or all combined, we found that the GALI was significantly associated with measures of activities of daily living, instrumental activity of daily living, and functional limitations (P < 0.001 in all cases). Associations were largest for activity of daily living and lowest though still high for functional limitations. For each measure, the magnitude of the association was similar across most countries. Overall, however, the GALI differed significantly between countries in terms of how it reflected each of the three disability measures (P < 0.001 in all cases). We suspect cross-country differences in the results may be due to variations in: the implementation of the EHIS, the perception of functioning and limitations, and the understanding of the GALI question. CONCLUSION: The study both confirms the relevance of this indicator to measure general activity limitations in the European population and the need for caution when comparing the level of the GALI from one country to another.

Polypharmacy and frailty: prevalence, relationship, and impact on mortality in a French sample of 2350 old people.

PURPOSE: To assess the prevalence of polypharmacy and frailty, to examine their association, and to establish their independent and combined effects on mortality in a sample of French old people. METHODS: This is a cross-sectional population study of people aged 70 years and over. A total of 2350 respondents were interviewed at home in 2008-2010. Frailty was defined as impairment in three domains or more among nutrition, energy, physical activity, strength, and mobility, in the absence of difficulties in basic activities of daily living. Mortality data were documented after a mean follow-up period of 2.6 years. RESULTS: Mean age of the population was 83.3 +/- 7.5 years, with 59.4% of women. Prevalence of frailty was 17.0%. Polypharmacy (5-9 drugs) was reported in 53.6% of the population, and excessive polypharmacy (10 drugs or more) in 13.8%. After adjustment for socio-demographic and health variables, polypharmacy and excessive polypharmacy were associated with frailty with odds ratio 1.77 [1.20-2.61] and 4.47 [2.37-8.42], respectively. Frailty (hazard ratio [HR] 2.56 [1.63-4.04]) and excessive polypharmacy (HR 1.83 [1.28-2.62]) were independent predictors of mortality. Compared with non-frail people without polypharmacy, frail people with excessive polypharmacy were six times more likely to die during the follow-up period (HR 6.30 [3.09-12.84]). CONCLUSION: By showing the independent and combined effects of polypharmacy and frailty on mortality risk, this study should reinforce the awareness of clinicians with regard to these factors, rather prevalent in old people.

Contribution of chronic diseases to the disability burden in a population 15 years and older, Belgium, 1997-2008.

BACKGROUND: Age-associated disability reduces quality of life in older populations and leads to wide-range implications for social and health policy. The identification of diseases that contribute to the disability burden is crucial to the development of prevention and intervention strategies to reduce disability. In this study, we assessed the contribution of chronic diseases to the prevalence of disability in Belgium. METHODS: Data from 35,837 individuals aged 15 years or older who participated in the 1997, 2001, 2004, or 2008 Belgian Health Interview Surveys were used. Disability was defined as difficulties in doing at least one of six activities of daily living (transfer in and out of bed, transfer in and out of chair, dressing, washing hands and face, feeding, and going to the toilet) and/or mobility limitations (ability to walk without stopping less than 200 m). Multiple additive regression models were fitted separately for men and women to estimate the age-specific background disability rate (experienced by everyone, independent of the presence of specific diseases) and disease-specific disability rates (disability rate in subjects who reported selected chronic diseases). RESULTS: Musculoskeletal, cardiovascular, and respiratory diseases were the main contributors to the disability burden in Belgium. Musculoskeletal diseases were the most prevalent diseases in men and women in all age groups. Neurological diseases and stroke were the most disabling diseases, i.e. caused the highest level of disability among the diseased individuals, in all age groups for men and women, respectively. Back pain was the main cause of disability in men aged 15 to 64 years, while heart attack was the major contributor to the disability prevalence in men aged 65 or older. Likewise, arthritis was the main cause of disability among women across all age groups. Depression was also an important contributor in young subjects (15-54 years). Cancer was not an important contributor to the disability prevalence in Belgium. CONCLUSIONS: To reduce the burden of disability in Belgium, interventions should target musculoskeletal, cardiovascular and respiratory diseases especially among elderly. Furthermore, attention should also be given to depression in young individuals.

Comparison of socio-economic indicators explaining inequalities in Healthy Life Years at age 50 in Europe: 2005 and 2010.

BACKGROUND: The first estimates of Healthy Life Years at age 50 (HLY50) across the EU25 countries in 2005 showed substantial variation in healthy ageing. We investigate whether factors contributing to HLY50 inequalities have changed between 2005 and 2010. METHODS: HLY50 for each country and year were calculated using Sullivan's method, applying the age-specific prevalence of activity limitation from the European Union Statistics on Income and Living Conditions (EU-SILC) survey to life tables. Inequalities in life expectancy at age 50 (LE50) and HLY50 between countries were defined as the difference between the maximum and minimum LE50 or HLY50. Relationships between HLY50 and macro-level socio-economic indicators were investigated using meta-regression. Men and women were analysed separately. RESULTS: Between 2005 and 2010 HLY50 inequalities for both men and women in Europe increased. In 2005 and 2010 HLY50 inequalities exceeded LE50 inequalities, particularly in the established EU15 countries in 2010 where HLY50 inequalities (men: 10.7 years; women: 12.5 years) were four times greater for men and three times for women than LE50 inequalities (men: 2.4 years; women: 4.1 years). Only material deprivation significantly explained variation in EU25 HLY50 in both years with, additionally, long-term unemployment in 2010. CONCLUSIONS: Our results suggest that inequalities in HLY50 across Europe are large, increasing and partly explained by levels of material deprivation. Moreover long-term unemployment has become more influential in explaining variation in HLY50 between 2005 and 2010.

Comparison of two methods to report potentially avoidable hospitalizations in France in 2012: a cross-sectional study.

BACKGROUND: Potentially avoidable hospitalizations represent an indirect measure of access to effective primary care. However many approaches have been proposed to measure them and results may differ considerably. This work aimed at examining the agreement between the Weissman and Ansari approaches in order to measure potentially avoidable hospitalizations in France. METHODS: Based on the 2012 French national hospital discharge database (Programme de Médicalisation des Systèmes d'Information), potentially avoidable hospitalizations were measured using two approaches proposed by Weissman et al. and by Ansari et al. Age- and sex-standardised rates were calculated in each department. The two approaches were compared for diagnosis groups, type of stay, severity, age, sex, and length of stay. RESULTS: The number and age-standardised rate of potentially avoidable hospitalizations estimated by the Weissman et al. and Ansari et al. approaches were 742,474 (13.3 cases per 1,000 inhabitants) and 510,206 (9.0 cases per 1,000 inhabitants), respectively. There are significant differences by conditions groups, age, length of stay, severity level, and proportion of medical stays between the Weissman and Ansari methods. CONCLUSIONS: Regarding potentially avoidable hospitalizations in France in 2012, the agreement between the Weissman and Ansari approaches is poor. The method used to measure potentially avoidable hospitalizations is critical, and might influence the assessment of accessibility and performance of primary care.

Ageing in the European Union.

The ageing of European populations presents health, long-term care, and welfare systems with new challenges. Although reports of ageing as a fundamental threat to the welfare state seem exaggerated, societies have to embrace various policy options to improve the robustness of health, long-term care, and welfare systems in Europe and to help people to stay healthy and active in old age. These policy options include prevention and health promotion, better self-care, increased coordination of care, improved management of hospital admissions and discharges, improved systems of long-term care, and new work and pension arrangements. Ageing of the health workforce is another challenge, and policies will need to be pursued that meet the particular needs of older workers (ie, those aged 50 years or older) while recruiting young practitioners.

The effect of smoking on the duration of life with and without disability, Belgium 1997-2011.

BACKGROUND: Smoking is the single most important health threat yet there is no consistency as to whether non-smokers experience a compression of years lived with disability compared to (ex-)smokers. The objectives of the manuscript are (1) to assess the effect of smoking on the average years lived without disability (Disability Free Life Expectancy (DFLE)) and with disability (Disability Life Expectancy (DLE)) and (2) to estimate the extent to which these effects are due to better survival or reduced disability in never smokers. METHODS: Data on disability and mortality were provided by the Belgian Health Interview Survey 1997 and 2001 and a 10 years mortality follow-up of the survey participants. Disability was defined as difficulties in activities of daily living (ADL), in mobility, in continence or in sensory (vision, hearing) functions. Poisson and multinomial logistic regression models were fitted to estimate the probabilities of death and the prevalence of disability by age, gender and smoking status adjusted for socioeconomic position. The Sullivan method was used to estimate DFLE and DLE at age 30. The contribution of mortality and of disability to smoking related differences in DFLE and DLE was assessed using decomposition methods. RESULTS: Compared to never smokers, ex-smokers have a shorter life expectancy (LE) and DFLE but the number of years lived with disability is somewhat larger. For both sexes, the higher disability prevalence is the main contributing factor to the difference in DFLE and DLE. Smokers have a shorter LE, DFLE and DLE compared to never smokers. Both higher mortality and higher disability prevalence contribute to the difference in DFLE, but mortality is more important among males. Although both male and female smokers experience higher disability prevalence, their higher mortality outweighs their disability disadvantage resulting in a shorter DLE. CONCLUSION: Smoking kills and shortens both life without and life with disability. Smoking related disability can however not be ignored, given its contribution to the excess years with disability especially in younger age groups.

Unmet health care needs of older people: prevalence and predictors in a French cross-sectional survey.

BACKGROUND: Unmet health care needs are associated with negative health outcomes, yet there is a paucity of data on this problem among older people. OBJECTIVE: To identify unmet health care needs and associated factors among older people in France. METHODS: This is a cross-sectional population study of people aged 70 years or older in which 2350 respondents were interviewed in 2008-10. During a standardized interview, a nurse examined health problems, functional abilities and use of health care resources. Unmet health care needs were defined as situations in which a participant needed health care and did not receive it. RESULTS: The mean age was 83.2 ± 7.4 years. Almost all participants reporting a chronic disease (98.6%) had consulted a physician in the previous 6 months. Unmet health care needs were found in 23.0% of the sample and mainly consisted of lack of dental care (prevalence of 17.7%), followed by lack of management of visual or hearing impairments (prevalence of 4.4% and 3.1%, respectively). Age was the main factor associated with unmet health care needs [compared with people aged 70-79: odds ratio80-89 years = 2.26 (1.70-3.03), odds ratio90 years and over = 3.85 (2.71-5.45)]. Other associated factors were regular smoking, homebound status, poor socioeconomic conditions, depression, limitations in instrumental activities of daily living and low medical density. CONCLUSION: Unmet health care needs affect almost one-quarter of older people in France. Efforts should be made to improve oral health and develop home care, especially for the oldest-olds.

Aging children of long-lived parents experience slower cognitive decline.

BACKGROUND: Parental longevity confers lower risks for some age-related diseases in offspring. We tested the association between parental longevity and late-life cognitive decline or dementia. METHODS: Data were from the Health and Retirement Study (HRS), a US national sample. Biennial cognitive assessment (Telephone Interview of Cognitive Status-Modified [TICS-m]) occurred for ages 64 years or older in 1996 through 2008 (maximum, 79 years), including physician-diagnosed memory disorder. Offspring were categorized into parental longevity groups based on gender-specific distributional cut points. Model covariates included race, respondents' education, and income status during childhood and adulthood. RESULTS: Offspring groups did not differ on TICS-m scores at baseline. During follow-up, offspring of two long-lived parents experienced 40% slower rates of TICS-m decline than those with no long-lived parents (95% confidence interval, 12-72; P=.003; n=4731). Increased parental longevity was also associated with lower risk of physician-diagnosed memory disorder. Estimates did not change after controlling for environmental variables. CONCLUSIONS: Parental longevity is associated inversely with cognitive decline and self-reported diagnosed memory disorders in aging offspring. Parental longevity may be a valuable trait for identifying early biomarkers for resistance to cognitive decline in aging.
