Gender-specific changes in well-being in older people with coronary heart disease: evidence from the English Longitudinal Study of Ageing.

OBJECTIVES: The objective of this study is to investigate gender-specific trajectories in well-being among older people with coronary heart disease (CHD) and to compare them with those of healthy people. METHOD: The study included a sample of 4496 participants from the first three waves of the English Longitudinal Study of Ageing (2002-2003 to 2006-2007). We measured well-being using quality of life (CASP-19; 'control', 'autonomy', 'pleasure' and 'self-realization') and depressive caseness (three or more symptoms on the CESD-8; Centre for Epidemiologic Study Depression scale). RESULTS: After adjustment, at two- and four-years follow-ups, women had three points higher quality of life than men (p < 0.001). When looking at each quality of life's domain we found that women reported higher scores of autonomy compared to men. The gender difference in the probability of having depressive caseness reduced to 7 percentage points at four-year follow-up from 13 percentage points in the previous occasions. Men's quality of life declined progressively over time by 3 points (p < 0.001) (equivalent to the effect of having diabetes) but no changes in prevalence of depressive caseness were found. Women's quality of life only declined after four-year follow-up by less than 2 points (p < 0.001), while in the same period their probability of reporting depressive caseness reduced by 6 percentage points (p < 0.001). CONCLUSION: Women had better quality of life than men in the two and four years following a CHD event, and were not more likely than men to report depressive caseness in the long term. Men's quality of life deteriorated progressively over time, among women it did not deteriorate in the first two years following a CHD event; women had a long-term improvement in depressive caseness.

Factors associated with remission of eczema in children: a population-based follow-up study.

The aim of this study was to analyse factors associated with remission of atopic dermatitis (AD) in childhood. A population-based AD cohort of 894 children aged 1-3 years from a cross-sectional baseline study in 2000 was followed up in 2005. The association between remission, background, health, lifestyle, and environmental variables was estimated with crude and multivariable logistic regression. At follow-up, 52% of the children had remission. Independent factors at baseline predicting remission were: milder eczema (adjusted odds ratio (aOR), 1.43; 95% confidence interval (95% CI) 1.16-1.77); later onset of eczema (aOR 1.40; 95% CI 1.08-1.80); non-flexural eczema (aOR 2.57; 95% CI 1.62-4.09); no food allergy (aOR 1.51; 95% CI 1.11-2.04), and rural living (aOR 1.48; 95% CI 1.07-2.05). Certain aspects of AD and rural living were important for remission, but despite the initial hypotheses to the contrary, the environmental factors examined in this paper were not substantial predictors of remission.

Incidence of pregnancy among women accessing antiretroviral therapy in urban Malawi: a retrospective cohort study.

Although previous studies investigated pregnancy rates among women on antiretroviral therapy (ART), incidence of, and factors associated with pregnancy among these women remain poorly understood. We, therefore, conducted a retrospective cohort study at a large public HIV clinic in Lilongwe, Malawi, between July 2007 and December 2010. At each clinic visit, pregnancy status was assessed. Time to event analysis was conducted using Poisson regression. Among 4,738 women, 589 pregnancies were observed. Pregnancy incidence was 9.3/100 person-years. After 6 months on ART, women on ART had similar total fertility rates to women in the urban population. In multivariable analysis, increasing age and advanced WHO clinical stage were associated with decreased probability of becoming pregnant while higher body mass index and longer time on ART were associated with increased probability of becoming pregnant. We recommend that ART clinics integrate comprehensive family planning services to address reproductive health needs among women on ART.

Social gradients in oral health in older adults: findings from the English longitudinal survey of aging.

OBJECTIVES: We examined prospective associations between socioeconomic position (SEP) markers and oral health outcomes in a national sample of older adults in England. METHODS: Data were from the English Longitudinal Survey of Aging, a national cohort study of community-dwelling people aged 50 years and older. SEP markers (education, occupation, household income, household wealth, subjective social status, and childhood SEP) and sociodemographic confounders (age, gender, and marital status) were from wave 1. We collected 3 self-reported oral health outcomes at wave 3: having natural teeth (dentate vs edentate), self-rated oral health, and oral impacts on daily life. Using multivariate logistic regression models, we estimated associations between each SEP indicator and each oral health outcome, adjusted for confounders. RESULTS: Irrespective of SEP marker, there were inverse graded associations between SEP and edentulousness, with proportionately more edentate participants at each lower SEP level. Lower SEP was also associated with worse self-rated oral health and oral impacts among dentate, but not among edentate, participants. CONCLUSIONS: There are consistent and clear social gradients in the oral health of older adults in England, with disparities evident throughout the SEP hierarchy.

Inequalities in health at older ages: a longitudinal investigation of the onset of illness and survival effects in England.

BACKGROUND: previous studies have suggested a decline in the relationship between socioeconomic circumstances and health or functioning in later life, but this may be due to survival effects. OBJECTIVE: to examine whether wealth gradients in the incidence of illness decline with age, and, if so, whether this decline is explained by differential mortality. METHODS: the study included participants in the first two waves of the English Longitudinal Study of Ageing (ELSA), a large national longitudinal study of the population aged 50+ in England, who reported good health, no functional impairment, or no heart disease at baseline. Wealth inequalities in onset of illness over 2 years were examined across age groups, with and without the inclusion of mortality. Outcome measures were functional impairment, heart disease, self-reported health, and all-cause mortality (in conjunction with self-reported health and disability) or circulatory-related mortality (in relation to heart disease). RESULTS: wealth predicted onset of functional impairment equally across age groups. For self-reported health and heart disease, wealth gradients in the onset of illness declined with age. Selective mortality contributed to this decline in the oldest age groups. CONCLUSIONS: socioeconomic inequality in developing new health problems persist into old age for certain illnesses, particularly functional impairment, but not for heart disease. Selective mortality explains only some of the decline in health inequalities with age.

Plasma homocysteine, but not folate or vitamin B-12, predicts mortality in older people in the United Kingdom.

There is uncertainty about the importance of plasma levels of homocysteine, vitamin B-12, and folate for all-cause and cardiovascular disease (CVD) mortality in older people. We examined the associations between plasma levels of folate, vitamin B-12, and homocysteine, and all-cause and CVD mortality among community-dwelling adults aged > or = 75 y living in the United Kingdom. In a population-based prospective cohort study, 853 men and women aged > or = 75 y were examined in 1995-98 as part of the Medical Research Council Trial of Assessment and Management of Older People in the Community. During a median follow-up of 7.6 y (5528 person-years of follow-up), 429 individuals (50.3%) died, including 185 from CVD. Individuals with plasma homocysteine levels in the top one-third compared with the bottom one-third had a 2-fold higher risk of all-cause mortality (hazard ratio, 2.20; 95% CI, 1.76, 2.75; P < 0.001) and CVD mortality (hazard ratio, 1.96; 95% CI, 1.39, 2.78; P < 0.001) after adjustment for age, sex, and other covariates. There was no association of plasma folate or vitamin B-12 levels with mortality. Our results extend previously reported associations of homocysteine with mortality, and the absence of associations of folate and vitamin B-12 with mortality, to the older population.

Socioeconomic status and health: the role of subjective social status.

Studies have suggested that subjective social status (SSS) is an important predictor of health. This study examined the link between SSS and health in old age and investigated whether SSS mediated the associations between objective indicators of socioeconomic status and health. It used cross-sectional data from the second wave (2004-2005) of the English Longitudinal Study of Ageing, which were collected through personal interviews and nurse visits. The study population consisted of 3368 men and 4065 women aged 52 years or older. The outcome measures included: self-rated health, long-standing illness, depression, hypertension, diabetes, central obesity, high-density lipoprotein cholesterol, triglycerides, fibrinogen, and C-reactive protein. The main independent variable was SSS measured using a scale representing a 10-rung ladder. Wealth, education, and occupational class were employed as covariates along with age and marital status and also, in additional analyses, as the main independent variables. Gender-specific logistic and linear regression analyses were performed. In age-adjusted analyses SSS was related positively to almost all health outcomes. Many of these relationships remained significant after adjustment for covariates. In men, SSS was significantly (p

Weight, shape, and mortality risk in older persons: elevated waist-hip ratio, not high body mass index, is associated with a greater risk of death.

BACKGROUND: Guidelines for optimal weight in older persons are limited by uncertainty about the ideal body mass index (BMI) or the usefulness of alternative anthropometric measures. OBJECTIVE: We investigated the association of BMI (in kg/m(2)), waist circumference, and waist-hip ratio (WHR) with mortality and cause-specific mortality. DESIGN: Subjects aged >/=75 y (n = 14 833) from 53 family practices in the United Kingdom underwent a health assessment that included measurement of BMI and waist and hip circumferences; they also were followed up for mortality. RESULTS: During a median follow-up of 5.9 y, 6649 subjects died (46% of circulatory causes). In nonsmoking men and women (90% of the cohort), compared with the lowest quintile of BMI (<23 in men and <22.3 in women), adjusted hazard ratios (HRs) for mortality were <1 for all other quintiles of BMI (P for trend = 0.0003 and 0.0001 in men and women, respectively). Increasing WHR was associated with increasing HRs in men and women (P for trend = 0.008 and 0.0002, respectively). BMI was not associated with circulatory mortality in men (P for trend = 0.667) and was negatively associated in women (P for trend = 0.004). WHR was positively related to circulatory mortality in both men and women (P for trend = 0.001 and 0.005, respectively). Waist circumference was not associated with all-cause or circulatory mortality. CONCLUSIONS: Current guidelines for BMI-based risk categories overestimate risks due to excess weight in persons aged >/=75 y. Increased mortality risk is more clearly indicated for relative abdominal obesity as measured by high WHR.

Cause-specific mortality in old age in relation to body mass index in middle age and in old age: follow-up of the Whitehall cohort of male civil servants.

BACKGROUND: The relevance of body mass index (BMI) to cause-specific mortality in old age is uncertain. OBJECTIVES: To examine cause-specific 5 year mortality in old age by BMI in old age and middle age (40-69 years). METHODS: Cox proportional hazards for mortality rates among 4862 former male civil servants in relation to quartiles of BMI measured when screened in 1968-70 and when resurveyed in 1997-98 (median age 76 years). RESULTS: The association between all-cause mortality after resurvey and BMI in old age was U-shaped with hazard ratios (HRs) of 1.3 (95% CI 1.1-1.5) for the lightest and heaviest categories relative to the middle two. Among 'healthy' men the lightest (<22.7 kg/m2) had greatest all-cause mortality. The heaviest men (>26.6 kg/m2) had increased risk of cardiovascular disease (CVD) mortality in the first two years or for the whole period if never-smokers. Respiratory mortality was inversely associated with BMI in old age [adjusted HR for trend per BMI category increase 0.6 (0.5-0.7)] but cancer mortality lacked a clear pattern. Net gain or loss of 10 kg or more between middle and old age was a strong predictor of all-cause and CVD mortality. CONCLUSIONS: The shape of the association between BMI in old age and mortality differs by cause of death. Major weight change over time is a warning signal for higher CVD mortality. Having BMI<22.7 kg/m2 in old age is associated with above-average mortality rates even if apparently healthy.

Cross-sectional survey of older peoples' views related to influenza vaccine uptake.

BACKGROUND: The population's views concerning influenza vaccine are important in maintaining high uptake of a vaccine that is required yearly to be effective. Little is also known about the views of the more vulnerable older population over the age of 74 years. METHODS: A cross-sectional survey of community dwelling people aged 75 years and over wh, previous participant was conducted using a postal questionnaire. Responses were analysed by vaccine uptake records and by socio-demographic and medical factors. RESULTS: 85% of men and 75% of women were vaccinated against influenza in the previous year. Over 80% reported being influenced by a recommendation by a health care worker. The most common reason reported for non uptake was good health (44%), or illness considered to be due to the vaccine (25%). An exploration of the crude associations with socio-economic status suggested there may be some differences in the population with these two main reasons. 81% of people reporting good health lived in owner occupied housing with central heating vs. 63% who did not state this as a reason (p = 0.04), whereas people reporting ill health due to the vaccine was associated with poorer social circumstances. 11% lived in the least deprived neighbourhood compared to 36% who did not state this as a reason (p = 0.05) and were less likely to be currently married than those who did not state this as a reason (25% vs 48% p = 0.05). CONCLUSION: Vaccine uptake was high, but non uptake was still noted in 1 in 4 women and 1 in 7 men aged over 74 years. Around 70% reported they would not have the vaccine in the following year. The divergent reasons for non-uptake, and the positive influence from a health care worker, suggests further uptake will require education and encouragement from a health care worker tailored towards the different views for not having influenza vaccination. Non-uptake of influenza vaccine because people viewed themselves as in good health may explain the modest socio-economic differentials in influenza vaccine uptake in elderly people noted elsewhere. Reporting of ill-health due to the vaccine may be associated with a different, poorer background.

Population-based multidimensional assessment of older people in UK general practice: a cluster-randomised factorial trial.

BACKGROUND: The benefit of multidimensional assessment and management of older people remains controversial. Most trials have been too small to produce adequate evidence to inform policy. We aimed to measure the effects of different approaches to assessment and management of older people. METHODS: We undertook a cluster-randomised factorial trial in 106 general practices (43219 eligible patients aged 75 years and older, 78% participation), comparing (1) universal versus targeted assessment and (2) subsequent management by hospital outpatient geriatric team versus the primary-care team. All participants received a brief multidimensional assessment followed by a nurse-led in-depth assessment in the universal group, whereas in the targeted group the in-depth assessment was offered only to those with problems established at the brief assessment. Referrals to the randomised team (geriatric management or primary care), other medical or social services, health-care workers, or agencies, and emergency referrals to the general practitioner were based on a standard protocol at the in-depth assessment. The primary endpoints were mortality, admissions to hospital and institution, and quality of life. Analysis was by intention to treat and per protocol. This trial has been assigned the International Standardised Randomised Controlled Trial Number ISRCTN23494848. FINDINGS: Mortality and hospital or institutional admissions did not differ between groups. During 3 years' follow-up, significant improvements in quality of life resulted from universal versus targeted assessment in terms of homecare, and from management by geriatric team versus primary-care team, in terms of mobility, social interaction, and morale. However, only the result for social interaction was consistent with a small but important effect. INTERPRETATION: The different forms of multidimensional assessment offered almost no differences in patient outcome.

Influence of short stature on the change in pulse pressure, systolic and diastolic blood pressure from age 36 to 53 years: an analysis using multilevel models.

BACKGROUND: Previous cross-sectional analyses of this cohort have shown that short height and leg length are associated with higher pulse pressure and systolic blood pressure in middle age. It is unclear how these adult measures of childhood growth influence the change in blood pressure as it increases with age. METHODS: Multilevel models were fitted to investigate associations between components of height and the change in blood pressure between 36, 43, and 53 years in a prospective national cohort of 1472 men and 1563 women followed-up since birth in 1946. RESULTS: Shorter height and leg length, but not trunk length, were associated with higher blood pressure, similarly in men and women. Longitudinal analyses showed that the effects of both height and leg length on pulse pressure and systolic blood pressure became significantly stronger with age. For example, the change in systolic blood pressure was found to be -0.021 mm Hg (95% confidence interval -0.029 to -0.013) per year lower for every centimetre increase in leg length (P < or = 0.001). In other words, the increase in systolic blood pressure over a 10 year period of a participant whose legs were 10 centimetres shorter was 2.1 mm Hg higher (P < or = 0.001), compared with a taller participant. Associations were independent of a number of potential confounders. CONCLUSIONS: These results support the hypothesis that short people may be more susceptible to the effects of ageing on the arterial tree. Childhood growth may contribute to the tracking of cardiovascular risk throughout life.

Are older people dying of depression? Findings from the Medical Research Council trial of the assessment and management of older people in the community.

OBJECTIVES: To examine the relationship between symptoms of depression and mortality in older people. DESIGN: Prospective longitudinal study. SETTING: Fifty-three general practices in the United Kingdom. PARTICIPANTS: Thirteen thousand ninety-seven people aged 75 and older participating in the Medical Research Council Trial of the Assessment and Management of Older People in the Community. MEASUREMENTS: Depression was measured using the 15-item Geriatric Depression Scale (GDS-15); the main outcome was all-cause mortality. RESULTS: Morbidity, disability, and lifestyle factors can explain most of the observed relationship between symptoms of depression and mortality (hazard ratio=1.75, 95% confidence interval (CI)=1.53-1.99), but after mutual adjustment for these factors, subjects who reported six or more symptoms of depression on the GDS-15 were still 27% more likely to have died by the end of the follow-up period than those below the threshold for depression (95% CI=1.11-1.45). CONCLUSION: The findings from this study suggest that depression confers a small risk for mortality in older people, not explained solely by poor health. The results support the encouragement of effective diagnosis, treatment, and support for individuals with depression as highlighted by the World Health Organization and the UK National Service Framework for older people.

Antioxidant vitamins and mortality in older persons: findings from the nutrition add-on study to the Medical Research Council Trial of Assessment and Management of Older People in the Community.

BACKGROUND: Older persons are at risk of both poor nutrition and increased oxidative stress. Plasma ascorbate concentrations fall with increasing age, and concentrations of other antioxidants may also be reduced. OBJECTIVE: The goal was to examine the association between antioxidants and mortality in older persons. DESIGN: We randomly selected persons aged 75-84 y from the lists of 51 British family practitioners taking part in a randomized trial of assessment of older persons. A total of 1214 participants provided a blood sample and were interviewed about their usual diet with the use of a food-frequency questionnaire. Statistical analyses were based on deaths after a median of 4.4 y of follow-up, and hazard ratios were estimated for quintiles of dietary or blood antioxidants. RESULTS: We found strong inverse trends for blood ascorbate concentrations with all-cause and cardiovascular disease mortality, which were only marginally reduced after adjustment for confounders or supplement use. Those in the lowest fifth (< 17 micromol/L) had the highest mortality, whereas those in the highest fifth (> 66 micromol/L) had a mortality risk nearly half that (hazard ratio = 0.54; 95% CI: 0.34, 0.84). Similar results were found after the exclusion of those subjects with cardiovascular disease or cancer at baseline (hazard ratio = 0.51; 0.28, 0.93). In fully adjusted models, there was no evidence for an influence of alpha-tocopherol, beta-carotene, or retinol on total mortality. Dietary antioxidants measured by the food-frequency questionnaire were not associated with all-cause or cardiovascular disease mortality. CONCLUSION: Low blood vitamin C concentrations in the older British population are strongly predictive of mortality.

Association of quality of life in old age in Britain with socioeconomic position: baseline data from a randomised controlled trial.

STUDY OBJECTIVE: To identify socioeconomic differentials in quality of life among older people and their explanatory factors. DESIGN: Baseline data from a cluster randomised controlled trial of the assessment and management of older people in primary care. Outcome measures were being in the worst quintile of scores for, respectively, the Philadelphia geriatric morale scale and four dimensions of functioning from the sickness impact profile (home management, mobility, self care, and social interaction). SETTING: 23 general practices in Britain. PARTICIPANTS: People aged 75 years and over on GP registers at the time of recruitment, excluding those in nursing homes or terminally ill. Of 9547 people eligible, 90% provided full information on quality of life and 6298 also did a brief assessment. RESULTS: The excess risk of poor quality of life for independent people renting rather than owning their home ranged from 27% for morale (95% CI 9% to 48%) to 62% for self care (95% CI 35% to 94%). Self reported health problems plus smoking and alcohol consumption accounted for half or more of the excess, depending on the outcome. Having a low socioeconomic position in middle age as well as in old age exacerbated the risks of poor outcomes. Among people living with someone other than spouse the excess risk from renting ranged from 24% (95% CI -10% to 70%) for poor home management to 93% (95% CI 30% to 180%) for poor morale. CONCLUSIONS: Older people retain the legacy of past socioeconomic position and are subject to current socioeconomic influences.

Trends in influenza vaccination uptake among people aged over 74 years, 1997-2000: survey of 73 general practices in Britain.

BACKGROUND: Influenza vaccination policy for elderly people in Britain has changed twice since 1997 to increase protection against influenza but there is no information available on how this has affected vaccine uptake, and socioeconomic variation therein, among people aged over 74 years. METHODS: Vaccination information for 1997-2000 was collected directly from general practices taking part in a MRC-funded Trial of the Assessment and Management of Older People in the Community. This was linked to information collected during assessments carried out as part of the Trial. Regression modelling was used to assess relative probabilities (as relative risks, RR) of having vaccination according to year, gender, age, area and individual socioeconomic characteristics. RESULTS: Out of 106 potential practices, 73 provided sufficient information to be included in the analysis. Uptake was 48% (95% CI 45%, 55%) in 1997 and did not increase substantially until 2000 when the uptake was a third higher at 63% (50%, 66%). Vaccination uptake was lower among women than men (RR 0.9), people aged 85 or more compared to people aged under 80 (RR 0.9), those in the most deprived areas (RR 0.8) compared to the least deprived, and was relatively high for those in owner-occupied homes with central heating compared to other non-supported housing (RR for remainder = 0.9). This pattern did not change over the years studied. CONCLUSIONS: Increased uptake in 2000 may have resulted from the additional financial resources given to practices; it was not at the expense of more disadvantaged socioeconomic groups but nor did they benefit disproportionately.

Cohort profile: the English longitudinal study of ageing.

The English Longitudinal Study of Ageing (ELSA) is a panel study of a representative cohort of men and women living in England aged ≥50 years. It was designed as a sister study to the Health and Retirement Study in the USA and is multidisciplinary in orientation, involving the collection of economic, social, psychological, cognitive, health, biological and genetic data. The study commenced in 2002, and the sample has been followed up every 2 years. Data are collected using computer-assisted personal interviews and self-completion questionnaires, with additional nurse visits for the assessment of biomarkers every 4 years. The original sample consisted of 11 391 members ranging in age from 50 to 100 years. ELSA is harmonized with ageing studies in other countries to facilitate international comparisons, and is linked to financial and health registry data. The data set is openly available to researchers and analysts soon after collection (http://www.esds.ac.uk/longitudinal/access/elsa/l5050.asp).

The bidirectional association between depressive symptoms and gait speed: evidence from the English Longitudinal Study of Ageing (ELSA).

BACKGROUND: Depressive symptoms and physical performance are inversely associated, but it is unclear whether their association is bidirectional. We examined whether the association between depressive symptoms and physical performance measured using gait speed is bidirectional. METHODS: We used a national sample of 4,581 community-dwelling people aged 60 years and older from the English Longitudinal Study of Ageing (from 2002-03 to 2008-09). We fitted Generalized Estimating Equation (GEE) regression models to analyse repeated measurements of gait speed (m/sec) and elevated depressive symptoms (defined as a score of ≥4 on the eight-item Center for Epidemiological Studies-Depression scale). RESULTS: Slower gait speed was associated with elevated depressive symptoms both concurrently and two years later. After adjustment for previous depressive symptoms and sociodemographic, clinical, lifestyle, psychosocial, and cognitive factors the concurrent association was partially explained (Odds Ratio [OR] 0.42, 95% confidence interval [CI], 0.30 to 0.59, per 1m/sec increase in gait speed) and the two-year lagged association fully (OR 0.75, 95% CI, 0.56 to 1.00). Elevated depressive symptoms were associated with slower gait speed. Full adjustment for covariates (including previous gait speed) partially explained both the concurrent (ß regression coefficient [ß] -0.038, 95% CI, -0.050 to -0.026, for participants with elevated depressive symptoms compared with those with no or one symptom) and the two-year lagged associations (ß -0.017, 95% CI, -0.030 to -0.005). Subthreshold depressive symptoms (defined as a score of two or three on the eight-item Center for Epidemiological Studies-Depression scale) were also associated with slower gait speed. Full adjustment for covariates partially explained both the concurrent (ß -0.029, 95% CI, -0.039 to -0.019, for participants with subthreshold symptoms compared with those with no or one symptom) and the two-year lagged associations (ß -0.011, 95% CI, -0.021 to -0.001). CONCLUSIONS: The inverse association between gait speed and depressive symptoms appears to be bidirectional.
