Social differences in traffic injury risks in childhood and youth--a literature review and a research agenda.

OBJECTIVES: The paper reviews the scientific literature concerning social differences in traffic injuries in childhood in order to highlight the current state of knowledge and to draw the main lines of a research agenda. METHOD: A conceptual framework is used that identifies the mechanisms through which social context, social position, and various exposures may interact in the determination of health inequalities. It is used as a frame for presenting the evidence accumulated so far concerning social differences in traffic injury in childhood, including pedestrian, cyclist, and vehicle passenger injuries. RESULTS: For most types of traffic injuries, mortality and morbidity are often higher among children from lower social positions and in more deprived socioeconomic areas. Whether the greater occurrence of injuries in deprived areas is a phenomenon attributable to the areas themselves, or merely a reflection of a wider pattern of injuries affecting lower socioeconomic groups, is unclear. There is evidence of an interaction effect between age and gender, and also between socioeconomic status and gender. CONCLUSIONS: The mechanisms leading to social inequalities in traffic injuries in childhood deserve greater scrutiny in future research. Further theoretical developments and empirical investigation will help define intervention needs and enable more effective targeted, long term prevention.

Inequality in the social consequences of illness: how well do people with long-term illness fare in the British and Swedish labor markets?

The demand for unskilled labor has collapsed across industrialized societies, including Britain and Sweden, and rates of unemployment and economic inactivity have increased. The result is a reduction in total employment, primarily among men. These trends could be expected to hit particularly hard those people with chronic illness. The study tests two opposing hypotheses: (1) the increasingly flexible, deregulated labor market in Britain would result in an increased number of new jobs, and thus better employment opportunities for unskilled workers, including those with chronic illness; (2) the more regulated labor market in Sweden, with the associated health and social policies, would provide greater opportunities for jobs and job security for workers with chronic illness. Analysis of data on men from the British General Household Survey and the Swedish Survey of Living Conditions, 1979-1995, showed that employment rates were higher and rates of unemployment and economic inactivity were lower in Sweden than in Britain, and the differences in these rates across socioeconomic groups and between those with and without chronic illness were smaller in Sweden. The results support the hypothesis that active labor market policies and employment protection may increase the opportunities for people with chronic illness to remain in work.

Child mortality in Stockholm during 1885-1910: the impact of household size and number of children in the family on the risk of death from measles.

Previous studies have associated overcrowding at the household level with increased mortality, especially from airborne diseases. This association may be confounded by associations with adverse socioeconomic conditions or low age at infection. This study investigated the effect of crowding on the risk of measles death. Individual entries in a population-based register and on death certificates for children aged 0-15 years living in one parish in Stockholm in 1885, 1891, and 1910 (n = 36,718) were used to analyze cause-specific and overall death rates in relation to household size and the number of children in the household, using Cox regression analysis. Bivariate analysis identified significant relations between crowding and the cause-specific risk of death, which were subsequently tested while controlling for other known risk factors for childhood death. Significant negative associations between crowding and the risk of death from pneumonia and bronchitis disappeared when controlling for other risk factors. A negative association between the risk of overall death and large household size became significantly positive when controlling for other risk factors. The increased risk of death from measles associated with proxies for crowding remained after controlling for other risk factors. In conclusion, crowding may have a statistically independent effect on the risk of death from measles.

The roles of social class of origin, achieved social class and intergenerational social mobility in explaining social-class inequalities in alcoholism among young men.

The aim of this study was to investigate the role of intergenerational health-related mobility in explaining social-class inequalities in alcoholism among young men. Data on social class of origin and on risk factors in childhood and adolescence, e.g. risk use of alcohol, were collected for 49,323 men, born 1949-51, at enlistment for compulsory military training in 1969/70. Information on achieved socioeconomic class was obtained from Sweden's 1975 census. Data on alcoholism diagnoses were collected from the national in-patient care register 1976-83. Risk indicators for alcoholism established in adolescence were found to be more common among downwardly mobile individuals, and also among stable manual workers, than among those who ended up as non-manual employees. Downwardly mobile individuals, and also stable manual workers, were also found to have an increased risk of alcoholism diagnosis. The increased relative risk could, to a considerable extent, be attributed to factors from childhood/adolescence. In this longitudinal study, it is shown that intergenerational social mobility associated with health-related factors, albeit not with illness itself, made a major contribution to explaining differences in alcoholism between social classes. Factors established in adolescence were important with regard to differences in alcoholism between social classes among young adults. But such adverse conditions did not seem to be well reflected by social class of origin.

Higher relative, but lower absolute risks of myocardial infarction in women than in men: analysis of some major risk factors in the SHEEP study. The SHEEP Study Group.

OBJECTIVES: Middle-aged men have often been the subjects of multifactorial studies of myocardial infarction (MI) risk factors. One major objective of the SHEEP study was to compare the effects of different MI risk factors in women and men. DESIGN: SHEEP (Stockholm Heart Epidemiology Program) is a population-based case-referent study of causes of MI (first event) in Swedish women and men aged 45-70 years. During the period 1992-94, 2246 cases of MI were identified; 34% of the cases were women and 27% of the cases were fatal. One referent per case was chosen randomly from the Stockholm County population after stratification for the case's sex and age. Logistic regression was used to estimate the relative risks associated with risk factors of primary interest (diabetes, hypercholesterolaemia, hypertriglyceridaemia, hypertension, overweight, physical inactivity, smoking and job strain). RESULTS: The relative risk estimates ranged from 1.5 to 4.4 in women and from 1.3 to 2.9 in men (results for nonfatal cases and their referents). None of the 95% confidence intervals included 1.0. The relative risks were higher in the women than in the men (101-180%). The absolute risks, however, were all lower in the women than in the men. Estimates of Rothman's synergy index for gender ranged from 1.0 (hypertension) to 1.8 (current smoking). CONCLUSIONS: The indications of some effect modification due to sex (stronger risks in men for certain exposures) invoke the question of possible mechanisms.

Lone mothers in Sweden: trends in health and socioeconomic circumstances, 1979-1995.

STUDY OBJECTIVE: To study trends in the health and socioeconomic circumstances of lone mothers in Sweden over the years 1979-1995, and to make comparisons with couple mothers over the same period. DESIGN: Analysis of data from the annual Survey of Living Conditions (ULF), conducted by Statistics Sweden from 1979-1995. Comparison of demographic, socioeconomic and health status of lone and couple mothers and how these have varied over the 17 years of the study. Main outcome measures include prevalence of self perceived general health and limiting longstanding illness. PARTICIPANTS AND SETTING: All lone mothers (n = 2776) and couple mothers (n = 16,935) aged 16 to 64 years in a random sample of the Swedish population in a series of cross sectional surveys carried out each year between 1979 and 1995. MAIN RESULTS: The socioeconomic conditions of lone mothers deteriorated during the period 1979-1995, with increasing unemployment and poverty rates. Lone mothers had worse health status than couple mothers throughout the period. In comparison with the first two periods, the prevalence of less than good health increased among both lone and couple mothers from the late 1980s onwards. For lone and couple mothers who were poor, their rates of less than good health were similar in the early 1980s, but in 1992-95 poor lone mothers were significantly more likely to report less than good health than poor couple mothers. Unemployed lone mothers had particularly high rates of ill health throughout the study period. CONCLUSIONS: As in other European countries, lone mothers are emerging as a vulnerable group in society in Sweden, especially in the economic climate of the 1990's. While they had very low rates of poverty and high employment rates in the 1980s, their situation has deteriorated with the economic recession of the 1990's. The health status of lone mothers, particularly those who are unemployed or poor, appears worse than that of couple mothers and in some circumstances may be deteriorating. Further study is needed to elucidate the mechanisms mediating their health disadvantage compared with couple mothers.

Exposure-dependent misclassification of exposure in interaction analyses.

The objectives of this paper are to analyze the consequences of exposure misclassification on effect estimates in interaction analysis, and to develop a mathematical equation for the potentially biased estimate. The main point is to identify situations in which misclassification of the first exposure, dependent on the second exposure but independent on outcome status, leads to overestimation or underestimation of the interaction effect. We show that misclassification theoretically can cause overestimation of the interaction effect. Nevertheless, because the categories that yield overestimation due to misclassification are fewer than the categories that yield underestimation, and misclassification in reality mostly is multidimensional (more than one category are biased simultaneously), it is more likely that the effect of misclassification is underestimation rather than overestimation. Misclassification in the categories that lead to overestimation is compensated by misclassification in the categories that lead to underestimation. The magnitude of the biased estimate depends on the prevalences of the misclassified exposure, stratified for the second exposure and the outcome-the lower the prevalence, the smaller the bias.

Is the effect of job strain on myocardial infarction risk due to interaction between high psychological demands and low decision latitude? Results from Stockholm Heart Epidemiology Program (SHEEP).

The objectives are to examine if the excess risk of myocardial infarction from exposure to job strain is due to interaction between high demands and low control and to analyse what role such an interaction has regarding socioeconomic differences in risk of myocardial infarction. The material is a population-based case-referent study having incident first events of myocardial infarction as outcome (SHEEP: Stockholm Heart Epidemiology Program). The analysis is restricted to males 45-64 yr of age with a more detailed analysis confined to those still working at inclusion. In total, 1047 cases and 1450 referents were included in the analysis. Exposure categories of job strain were formed from self reported questionnaire information. The results show that high demands and low decision latitude interact with a synergy index of 7.5 (95% C.I.: 1.8-30.6) providing empirical support for the core mechanism of the job strain model. Manual workers are more susceptible when exposed to job strain and its components and this increased susceptibility explains about 25-50% of the relative excess risk among manual workers. Low decision latitude may also, as a causal link, explain about 30% of the socioeconomic difference in risk of myocardial infarction. The distinction between the interaction and the causal link mechanisms identifies new etiologic questions and intervention alternatives. The specific causes of the increased susceptibility among manual workers to job strain and its components seem to be an interesting and important research question.

Explanations of social class differences in alcoholism among young men.

The aim of this study was to analyse the role of differences in alcohol consumption and other risk factors for alcoholism established in late adolescence, for later differences in the distribution of alcoholism between social classes among young men. Data on risk factors in childhood and adolescence, e.g. risk use of alcohol, was collected among 49,323 men, born 1949-1951, at conscription for compulsory military training 1969/1970. Data on socio-economic group was obtained from the 1975 census and data on alcoholism diagnoses from the national in-patient care register 1976-1983. Several risk factors for alcoholism, such as risk use of alcohol, psychiatric diagnosis at conscription, parental divorce, low emotional control and contact with police and child care authorities, seemed to be more common among those who were recruited to blue-collar occupations compared to those who were recruited to non-manual occupations. In multivariate analyses, taking the background variables into consideration, the increased relative risks among manual workers for alcoholism diagnoses, found in univariate analyses, diminished considerably. Several risk factors had a stronger effect on the outcome among unskilled workers compared with non-manual employees at medium or higher degree. It is concluded that risk factors for poor health established in late adolescence could explain much of the increased relative risk of alcoholism among young unskilled and skilled male workers in this study.

Socioeconomic differences in risk of myocardial infarction 1971-1994 in Sweden: time trends, relative risks and population attributable risks.

BACKGROUND: The general trend in incidence of myocardial infarction (MI) in the Stockholm area changed from increasing to decreasing around 1980. The objective of this study is to examine time trends in incidence in major socioeconomic strata, relative risk between socioeconomic groups and population risk attributable to socioeconomic differences during this period. METHODS: All cases of MI from 1971 to 1986 were identified from hospital discharge and cause-of-death registers. Person-years for each year of follow-up were calculated from the population register in the Stockholm region 1971-1986. Census registers were used for information on socioeconomic status. Register information was individually linked through the Swedish personal identification number. Supplementary information for 1992-1994 was taken from the case-control study SHEEP (Stockholm Heart Epidemiology Program). RESULTS: The decline in MI risk among male high- and middle-level employees started in 1976 and in male manual workers in 1981. For women incidence increased from 1971 to 1986 among manual workers and decreased among high- and middle-level employees. The increase over time of the relative risk from low socioeconomic position continued into the 1990s. Despite the reduction of the category of manual workers, the population attributable risk from socioeconomic differences also increased over time. The process of social change influencing the size of the socioeconomic groups contributes to the change in time trends of MI morbidity. CONCLUSIONS: The increase over time of relative and population attributable risks of MI from low socioeconomic status add to the public health importance of social inequity.

Use of a historical register in social epidemiology: child mortality in Stockholm at the turn of the 19th century.

This study describes the age- and cause-specific levels and social determinants of high child mortality in Stockholm around the turn of the century. The study is based on computerized individual level sociodemographic information and the death certificates of children aged 0-15 years residing in Maria parish in Stockholm during the years 1885, 1891 and 1910 (n = 36,718) from a historical register (the Roteman archives). The usefulness of such data for further studies in social epidemiology is discussed. Age-specific rates and major causes of death compared well with other studies. Low social class and being born out of wedlock increased the overall risk of death in early childhood. Data appear valid and may be useful in social epidemiology. Further analyses of data from the Roteman archives may contribute to the understanding of causes behind high levels of cause- specific child mortality and trends in mortality in relation to societal change.
