Quality of life at older ages: evidence from the English longitudinal study of aging (wave 1).

OBJECTIVES: To investigate whether longstanding illnesses, social context, and current socioeconomic circumstances predict quality of life. DESIGN: Secondary analysis of wave 1 of the English longitudinal study of aging. Missing data were imputed and multiple regression analyses conducted. SETTING: England, 2002 PARTICIPANTS: Nationally representative sample of non-institutionalised adults living in England (n = 11 234, 54.5% women, age 65.1 (SD 10.2) years). MAIN OUTCOME MEASURE: Quality of life as measured by CASP-19, a 19 item Likert scaled index. RESULTS: The quality of life was reduced by depression (beta -0.265), poor perceived financial situation (beta -0.157), limitations in mobility (beta -0.124), difficulties with everyday activities (beta -0.112), and limiting longstanding illness (beta -0.112). The quality of life was improved by trusting relationships with family (beta 0.105) and friends (beta 0.078), frequent contacts with friends (beta 0.059), living in good neighbourhoods (beta 0.103), and having two cars (beta 0.066). The regression models explained 48% variation in CASP-19 scores. There were slight differences between age groups and between men and women. CONCLUSIONS: Efforts to improve quality of life in early old age need to address financial hardships, functionally limiting disease, lack of at least one trusting relationship, and inability to move out of a disfavoured neighbourhood. There is the potential for improved quality of life in early old age (the third age) if these factors are controlled.

Life-course influences on mortality at older ages: evidence from the Oslo Mortality Study.

Several studies have investigated the cumulative influence of disadvantage acting from early to adult life. And they suggest that risk of death increases in a cumulative fashion. Few studies have investigated the life-course influences on social inequality in mortality in early old age. In this study we wanted to follow a cohort through their adult working age into retirement and investigate pathways that may give increased risk of mortality. A cohort of all inhabitants in the age range 68-72 who lived in the municipality of Oslo on 1st January 1990 was selected. Data were obtained by linking censuses from 1960, 1970 and 1980 with tax registry in 1990 and death registry 1990-1998. Independent variables were occupational class in 1960, 1970 and 1980 and household income in 1990. Occupational class was coded as manual and non-manual and household income as above or below median household income. A cumulative model was developed by adding times of disadvantage. Then a pathway model was developed which investigated the specific trajectories individuals followed. Most of the increased risk of death was explained by individuals' social conditions in 1990. In the cumulative model, there was no clear gradient in the groups between the bottom and top categories. This suggests that the cumulative model is not important in the high mortality age and that the relative importance of a cumulative effect varies by stages of the life course.

What influences diet in early old age? Prospective and cross-sectional analyses of the Boyd Orr cohort.

BACKGROUND: The aim of this study is to identify the socio-economic and health-related factors in childhood and later life associated with healthy eating in early old age. METHODS: The study is based on surviving members of the Boyd Orr cohort aged 61-80 years. Data are available on household diet and socio-economic position in childhood and on health and social circumstances in later life. A 12-item Healthy Diet Score (HDS) for each subject was constructed from food frequency questionnaire responses. Complete data on all exposures examined were available for 1234 cohort members. RESULTS: Over 50% of study members had inadequacies in at least half of the 12 markers of diet quality. In multivariable models having a childhood diet which was rich in vegetables was associated with a healthy diet in early old age. The HDS for those in the upper quartile of childhood vegetable intake was 0.30 (95% confidence interval -0.01 to 0.61) higher than those with the lowest intake levels (P-trend across quartiles = 0.04). The adult factors that were most strongly associated with a healthy diet were not smoking, being an owner-occupier, and taking anti-hypertensive medication. CONCLUSION: Our analysis indicates that diet in early old age is influenced by childhood vegetable consumption, current socio-economic position, and smoking. Interventions for improving the diet of older people could usefully focus on both encouragement of healthy diet choices from an early age and higher levels of income or nutritional support for older people.

Class, cohort, and consumption: the British experience of the third age.

OBJECTIVE: This study examines the relative effect of historical and social class location on engagement in consumerism within two different cohorts of retired people in the United Kingdom. METHODS: With use of self-reported data from the retired members of a nationally representative survey, an index of consumption was constructed. Its internal reliability was analysed and analyses of variance performed to examine the impact of class of origin, cohort, and class at exit on levels of self-reported "consumerism." RESULT: The index demonstrated sufficient internal reliability to provide an operational measurement of "consumerism" within this retired population. Analyses of variance confirmed that class at exit and cohort but not class of origin contributed significantly to variation in levels of consumerism. These effects were not mediated by cohort differences in health. DISCUSSION: Occupational standing immediately before retirement was associated with "consumerism" after retirement. This is unsurprising. The results also show that birth cohort exercised a stronger historical influence on current consumption in later life than did class background (i.e., paternal social class). This supports our thesis that the limited but increasing immersion in mass consumer society of successive cohorts who were born and grew up earlier in the 20th century continues to be reflected in levels of "consumerism" in retirement.

High rates of ischaemic heart disease in Scotland are not explained by conventional risk factors.

STUDY OBJECTIVES: To (1) compare prevalence of socioeconomic, behavioural, and physiological ischaemic heart disease (IHD) risk factors in Scotland with a comparable nation (England) and (2) find out if their distribution explains Scotland's comparatively higher IHD rate (1.62 (1.30, 2.02)). DESIGN, SETTING, AND PARTICIPANTS: Cross sectional, individual level observational study with data on socioeconomic, behavioural, and physiological characteristics, 6064 respondents from Scotland and England, (2362 and 3702 respectively), aged 45-74 and with data on all required items. MAIN RESULTS: There were significant and meaningful differences between the Scottish and English in the prevalence of several IHD risk factors. However, a substantially and significantly higher risk of IHD persisted among the Scottish respondents (1.50 (1.17, 1.91)) despite control for a wide range of risk factors. CONCLUSIONS: Interpretation must be cautious because these are cross sectional data, however higher levels of conventional IHD risk factors contribute to but do not explain the comparatively high rates of IHD in Scotland. Alternative explanations for, and policy interventions to tackle, Scottish rates of IHD must be considered.

Can we disentangle life course processes of accumulation, critical period and social mobility? An analysis of disadvantaged socio-economic positions and myocardial infarction in the Stockholm Heart Epidemiology Program.

The accumulation hypothesis would propose that the longer the duration of exposure to disadvantaged socio-economic position, the greater the risk of myocardial infarction. However there may be a danger of confounding between accumulation and possibly more complex combinations of critical periods of exposure and social mobility. The objective of this paper is to investigate the possibility of distinguishing between these alternatives. We used a population based case-control study (Stockholm Heart Epidemiology Programme) of all incident first events of myocardial infarction among men and women, living in the Stockholm region 1992-94. The analyses were restricted to men 53-70 years, 511 cases and 716 controls. From a full occupational history each subject was categorized as manual worker or non-manual at three stages of the life course, childhood (from parent's occupation), at the ages 25-29 and 51-55, resulting in 8 possible socio-economic trajectories. We found a graded response to the accumulation of disadvantaged socio-economic positions over the life course. However, we also found evidence for effects of critical periods and of social mobility. A conceptual analysis showed that there are, for theoretical reasons, only a limited number of trajectories available, too small to form distinct empirical categories of each hypothesis. The empirical task of disentangling the life course hypotheses of critical period, social mobility and accumulation is therefore comparable to the problem of separating age, period, and cohort effects. Accordingly, the interpretation must depend on prior knowledge of more specific causal mechanisms.

The use of quantitative medical sociology.

The present article reviews, in relation to quantitative work on the social structure, papers published in Sociology of Health and Illness during its first 25 years. Each issue published during the years 1979-2002 has been examined; and quantitative papers, relating to various aspects of the social structure, have been identified. Such papers are found to have formed a minor but substantively significant theme within the Journal. These contributions situate the journal between sociology and social epidemiology. Articles in the Journal, for example, have been part of sociological debates about the measurement of social class, and of social epidemiological debates about the relationship between income distribution and population health. The contribution of Sociology of Health and Illness to a number of such debates is reviewed. The article concludes that the present situation, in particular the intellectual crisis in social epidemiology and social science investment in large data sets, gives the Journal the chance to build on this distinguished tradition by encouraging, through its publication policy, the further development of quantitative medical sociology.

Tackling health inequalities in the United Kingdom: the progress and pitfalls of policy.

GOAL: Assess the progress and pitfalls of current United Kingdom (U.K.) policies to reduce health inequalities. OBJECTIVES: (1) Describe the context enabling health inequalities to get onto the policy agenda in the United Kingdom. (2) Categorize and assess selected current U.K. policies that may affect health inequalities. (3) Apply the "policy windows" model to understand the issues faced in formulating and implementing such policies. (4) Examine the emerging policy challenges in the U.K. and elsewhere. DATA SOURCES: Official documents, secondary analyses, and interviews with policymakers. STUDY DESIGN: Qualitative, policy analysis. DATA COLLECTION: 2001-2002. The methods were divided into two stages. The first identified policies which were connected with individual inquiry recommendations. The second involved case-studies of three policies areas which were thought to be crucial in tackling health inequalities. Both stages involved interviews with policymakers and documentary analysis. PRINCIPAL FINDINGS: (1) The current U.K. government stated a commitment to reducing health inequalities. (2) The government has begun to implement policies that address the wider determinants. (3) Some progress is evident but many indicators remain stubborn. (4) Difficulties remain in terms of coordinating policies across government and measuring progress. (5) The "policy windows" model explains the limited extent of progress and highlights current and possible future pitfalls. (6) The U.K.'s experience has lessons for other governments involved in tackling health inequalities. CONCLUSIONS: Health inequalities are on the agenda of U.K. government policy and steps have been made to address them. There are some signs of progress but much remains to be done including overcoming some of the perverse incentives at the national level, improving joint working, ensuring appropriate measures of performance/progress, and improving monitoring arrangements. A conceptual policy model aids understanding and points to ways of sustaining and extending the recent progress and overcoming pitfalls.

Elevated risk of high blood pressure: climate and the inverse housing law.

BACKGROUND: In previous work the authors identified an 'inverse housing law' in Britain such that housing quality tends to be worse in areas of harsh climate than in areas where the climate is more benign. This study investigates whether an individual's risk of hypertension is associated with such a 'mismatch' between the quality of their housing and the climate to which they have been exposed. METHODS: Cross-sectional observational study based on Britain. Data came from the 5663 Health and Lifestyle Survey (HALS) participants for whom all relevant items were available. A two-stage study design was employed. First, the relationship between exposure to colder climate and housing quality was established. Second, the impact on risk of hypertension was determined for level of exposure to colder climate and housing quality. RESULTS: Analysis confirmed that amongst survey respondents, those with greater exposure to colder climate are more likely (1.32, 95% CI: 1.18-1.42) to live in poor quality housing than those with lower exposure to colder climate. This combination of higher exposure to colder climate plus residence in worse quality housing raises significantly the risk of diastolic hypertension (1.45, 95% CI: 1.18-1.77) and, more weakly, systolic hypertension (1.25, 95% CI: 1.01-1.53). CONCLUSIONS: There appears to be an 'inverse housing law' in Britain, whereby longer term residents of relatively cold areas are also more likely to live in worse quality housing and this combination of circumstances is associated with significantly higher risk of diastolic hypertension. The findings provide an example of how long term exposure to an adverse environment, which may stem from material disadvantage, can damage health.
