The socioeconomic status of older adults: How should we measure it in studies of health inequalities?

STUDY OBJECTIVE To identify which of seven indicators of socioeconomic status used singly or combined with one other would be most useful in studies of health inequalities in the older population. DESIGN Secondary analysis of socioeconomic and health data in a two wave survey. SETTING Great Britain. Participants were interviewed at home by a trained interviewer. PARTICIPANTS Nationally representative sample of 3543 adults aged 55–69 interviewed in 1988/9, 2243 of whom were interviewed again in 1994. METHODS Desirable features of socioeconomic measurement systems for identifying health inequalities in older populations were identified with reference to the literature. Logistic regression was used to examine variations in self reported health by seven indicators of socioeconomic status. The pair of indicators with the greatest explanatory power was identified. MAIN RESULTS All indicators were significantly associated with differences in self reported health. The best pair of variables, according to criteria used, was educational qualification or social class paired with a deprivation indicator. DISCUSSION For a range of reasons the measurement of socioeconomic status is particularly challenging in older age groups. Extending our knowledge of which indicators work well in analyses and are relatively easy to collect should help both further study of health inequalities in the older population and appropriate planning.

Health inequalities in the older population: the role of personal capital, social resources and socio-economic circumstances

Older people now constitute the majority of those with health problems in developed countries so an understanding of health variations in later life is increasingly important. In this paper, we use data from three rounds of the Health Survey for England, a large nationally representative sample, to analyse variations in the health of adults aged 65-84 by indicators of attributes acquired in childhood and young adulthood, termed personal capital; and by current social resources and current socio-economic circumstances, while controlling for smoking behaviour and age. We used six indicators of health status in the analysis, four based on self-reports and two based on nurse collected data, which we hypothesised would identify different dimensions of health. Results showed that socio-economic indicators, particularly receipt of income support (a marker of poverty) were most consistently associated with raised odds of poor health outcomes. Associations between marital status and health were in some cases not in the expected direction. This may reflect bias arising from exclusion of the institutional population (although among those under 85 the proportion in institutions is very low) but merits further investigation, especially as the marital status composition of the older population is changing. Analysis of deviance showed that social resources (marital status and social support) had the greatest effect on the indicator of psychological health (GHQ) and also contributed significantly to variation in self-rated health, but among women not to variation in taking three or more medicines and among men not to self-reported long-standing illnesses. Smoking, in contrast, was much more strongly associated with these indicators than with self-rated health. These results are consistent with the view that self-rated health may provide a holistic indicator of health in the sense of well-being, whereas measures such as taking prescribed medications may be more indicative of specific morbidities. The results emphasise again the need to consider both socio-economic and socio-psychological influences on later life health.

Between elderly parents and adult children: a new look at the intergenerational care provided by the ‘sandwich generation’

The ‘sandwich generation’ has been conceptualised as those mid-life adults who simultaneously raise dependent children and care for frail elderly parents. Such a combination of dependants is in fact very unusual, and the more common situation is when adults in late mid-life or early old age have one or more surviving parents and adult but still partly dependent children. It can be hypothesised that for parents in this pivotal position, the demands from adult children and from elderly parents compete, with the result that those who provide help to one are less likely to provide help to the other. An alternative hypothesis, however, is that family solidarity has an important influence but is not universal, so that some pivotal-generation parents engage in intergenerational exchange in both directions, and there is a positive association between helping parents and helping children. To investigate this question, the paper presents an analysis of data from two broadly comparable national surveys, in Great Britain and the United States, on the care provided by women aged 55–69 years to their descendent and ascendent relatives. The results show that around one-third of the women reported providing help to members of both generations, and that around one-fifth provided support to neither. They broadly support the solidarity hypothesis, but provide some evidence that having three or more children is associated with a reduced likelihood of providing help to a parent.

Ageing and vulnerable elderly people: European perspectives

This paper considers the processes and circumstances that create vulnerability among older people, specifically to a very poor quality of life or an untimely or degrading death. Models of ageing processes are used to define vulnerable older people as those whose reserve capacity falls below the threshold needed to cope successfully with the challenges they face. Compensatory supports may intervene to mitigate the effects of challenges and to rebuild reserve. The dimensions of reserve, challenges and compensation are discussed, with emphasis on demographic and other influences on the availability of family and social support. Policy initiatives to reduce vulnerability can focus on each part of the dynamic process that creates vulnerability, namely, ensuring that people reach later life with ‘reserve’, reducing the challenges they face in later life, and providing adequate compensatory supports. The promotion through the lifecourse of healthy lifestyles and the acquisition of coping skills, strong family and social ties, active interests, and savings and assets, will develop reserves and ensure that they are strong in later life. Some of the physical and psychological challenges that people may face as they age cannot be modified, but others can. Interventions to develop compensatory supports include access to good acute care and rehabilitation when needed, substitute professional social and psychological help in times of crisis, long-term help and income support. Our knowledge of which interventions are most effective is however limited by the paucity of rigorous evaluation studies.

Completeness and usability of ethnicity data in UK-based primary care and hospital databases

Background Ethnicity recording across the National Health Service (NHS) has improved dramatically over the past decade. This study profiles the completeness, consistency and representativeness of routinely collected ethnicity data in both primary care and hospital settings. Methods Completeness and consistency of ethnicity recording was examined in the Clinical Practice Research Datalink (CPRD) and Hospital Episode Statistics (HES), and the ethnic breakdown of the CPRD was compared with that of the 2011 UK censuses. Results 27.1% of all patients in the CPRD (1990–2012) have ethnicity recorded. This proportion rises to 78.3% for patients registered since April 2006. The ethnic breakdown of the CPRD is comparable to the UK censuses. 79.4% of HES inpatients, 46.8% of outpatients and 26.8% of A&E patients had their ethnicity recorded. Amongst those with ethnicity recorded on >1 occasion, consistency was over 90% in all data sets except for HES inpatients. Combining CPRD and HES increased completeness to 97%, with 85% of patients having the same ethnicity recorded in both databases. Conclusions Using CPRD ethnicity from 2006 onwards maximizes completeness and comparability with the UK population. High concordance within and across NHS sources suggests these data are of high value when examining the continuum of care. Poor completeness and consistency of A&E and outpatient data render these sources unreliable.

Contacts between elderly parents and their children in four European countries: current patterns and future prospects

Frequency of contacts with the family is an indicator of the strength of intergenerational exchange and potential support for older people. Although the availability of children clearly represents a constraint on potential family support, the extent of interaction with and support received from children depends on factors other than demographic availability alone. This study examined the effects of socio-economic and demographic variables on weekly contacts with children in Great Britain, Italy, Finland and The Netherlands using representative survey data which included information on availability of children and extent of contact. Our results confirm the higher level of parent adult-child contact in Italy than in northern European countries, but levels of contact in all the countries considered were high. Multivariate analysis showed that in most countries characteristics such as divorce were associated with a reduced probability of contact between fathers and children; in Finland this also influenced contact between mothers and children. Analyses are also included of possible future scenarios of contact with children that combine the observed effects of the explanatory variables with hypothetical changes in population distribution.

Contact between Adult Children and Their Parents in Great Britain 1986–99

Three nationally representative British data sets have been used to analyse trends and differentials in contact between adult children aged 22–54 years and their non-coresident mothers and fathers. The results show that having at-least-weekly contact is positively associated with children being female, lower levels of education, and living in the North, and negatively associated with age, number of siblings, and being a tenant in the privately rented sector. Daughters had more contact with mothers than with fathers, and children were less likely to see their fathers at least weekly if their mother was no longer alive, indicating a strong gender dimension to intergenerational contact. These associations were observed whether or not proximity, which was very strongly associated with contact, was controlled for in the analysis. Odds of at-least-weekly contact with parents were significantly lower in 1995 than in 1986, but there was no significant difference between 1999 and 1986, and so no clear indication of a trend towards reduced contact.

Trends in, and transitions to, institutional residence among older people in England and Wales, 1971-91.

OBJECTIVES: To compare transitions from private households to institutions between 1971-81 and 1981-91 among elderly people and see whether (1) differentials in the risk of institutionalisation changed and (2) whether the risk was higher in the second period. DESIGN: Cross sequential analysis of data from the Office of National Statistics longitudinal study, a record linkage study which included individual level data from three national censuses, (1971, 1981, and 1991) and linked vital registration data. SUBJECTS: Altogether 26,400 people aged 65 and over in 1971-81 and 32,500 persons aged 65 and over in 1981-91. These samples represent 1% of the population of England and Wales. RESULTS: In both periods models including age, housing tenure, and marital status or household/family type terms fitted the data reasonably well. The effect of age was stronger in the second decade, while that of marital status was reduced. The risk of transition to an institution was nearly 33-52% higher in the second decade after controlling for these factors. CONCLUSIONS: During the 1980s the availability of state financed institutional care increased substantially; a growth which the 1990 NHS and Community Care Act was designed to reverse. Increased access to institutional care undoubtedly is one factor underlying the higher transition rate to institutions observed in 1981-91 than for the previous decade. During 1981-91, transitions to live with relatives also declined substantially. It is not clear whether this simply represents the continuation of a previous trend or whether the increased availability of institutional care led to some substitution for family care. Either interpretation has worrying implications for policy makers keen to promote care in the community.

Changes in life satisfaction over a two and a half year period among very elderly people living in London

Research evidence concerning the contributions of social networks and support to the subjective wellbeing (i.e. life satisfaction) of older persons is not consistent. This paper reports the results of an investigation of the effects life satisfaction at baseline, social network type and health status, on life satisfaction at follow-up at two and a half years later among people ages 85+ living in the East end of London. The percentage of the total variation in overall life satisfaction which was explained by the model was 47%. Baseline life satisfaction score explained most of this (43%), and the remaining variation was explained largely by functional status and age. Previous analyses of baseline life satisfaction reported that health and functional status had accounted for most of the variation between groups, far more than social network and support variables.

Fertility history and cause-specific mortality: A register-based analysis of complete cohorts of Norwegian women and men

The relationship between womens reproductive histories and later all-cause mortality has been investigated in several studies, with mixed results. Some studies have also considered cause-specific mortality and some have included men, but none has done both. We analyse associations between parity and age of first birth for women and men across 11 cause-of-death groupings using Norwegian register data for complete cohorts born 1935-1968 whose mortality was observed 1980-2003 (i.e. at ages 45-68). Age, period, educational level, marital status, region of residence and population size of municipality were included as co-variates. In total, there were 63,000 deaths. Results showed that relative to parents of two children, childless men and women and those with one child had higher mortality risks for nearly all cause of death groupings. High parity (4+ children) was associated with raised male mortality from accidents and violence and higher mortality from cancer of the cervix among women. For other cause and gender groupings there was either little difference between those with two children and those of higher parities or an overall negative association between parity and mortality. Among men with the lowest level of education, however, high parity was positively associated with mortality from circulatory diseases. For all causes except female breast cancer, there was an inverse association between age at first birth and mortality risk. Similarities observed across cause groups and for women and men suggest that much of the fertility-mortality relationship is a result of selection or effects of reproductive behaviour on lifestyle. The latter may include both beneficial effects and harmful stress responses. However, physiological mechanisms are most probably important for some causes of death for women. Research on associations between parenting histories, health related behaviours, social support exchanges and reported or measured stress is needed to clarify mechanisms underlying the associations reported here.
