We have made a comparative analysis of these inequalities in the United States and 11 western European countries. The aims of the analysis were (1) to compare the size of inequalities in cardiovascular disease mortality between countries, and (2) to explore the possible contribution of cardiovascular risk factors to the explanation of between-country differences in inequalities in cardiovascular disease mortality. DATA AND METHODS: Data on ischaemic heart disease, cerebrovascular disease and total cardiovascular disease mortality by occupational class and/or educational level were obtained from national longitudinal or unlinked cross-sectional studies. Data on smoking, alcohol consumption, overweight and infrequent consumption of fresh vegetables by occupational class and/or educational level were obtained from national health interview or multipurpose surveys and from the European Union's Eurobarometer survey. Age-adjusted rate ratios for mortality were correlated with age-adjusted odds ratios for the behavioural risk factors. RESULTS: In all countries mortality from cardiovascular diseases is higher among persons with lower occupational class or lower educational level. Within western Europe, a north-south gradient is apparent, with relative and absolute inequalities being larger in the north than in the south. For ischaemic heart disease, but not for cerebrovascular disease, an even more striking north-south gradient is seen, with some 'reverse' inequalities in southern Europe. The United States occupy intermediate positions on most indicators. Inequalities in cardiovascular disease mortality are associated with inequalities in some risk factors, especially cigarette smoking and excessive alcohol consumption. CONCLUSIONS: Socioeconomic inequalities in cardiovascular disease mortality are a major public health problem in most industrialized countries. Closing the gap between low and high socioeconomic groups offers great potential for reducing cardiovascular disease mortality. Developing effective methods of behavioural risk factor reduction in the lower socioeconomic groups should be a top priority in cardiovascular disease prevention. http://repub.eur.nl/res/pub/9017/ 1999-01-01T00:00:00Z OBJECTIVES: Twelve countries were compared with respect to occupational class differences in ischemic heart disease mortality in order to identify factors that are associated with smaller or larger mortality differences. METHODS: Data on mortality by occupational class among men aged 30 to 64 years were obtained from national longitudinal or cross-sectional studies for the 1980s. A common occupational class scheme was applied to most countries. Potential effects of the main data problems were evaluated quantitatively. RESULTS: A north-south contrast existed within Europe. In England and Wales, Ireland, and Nordic countries, manual classes had higher mortality rates than nonmanual classes. In France, Switzerland, and Mediterranean countries, manual classes had mortality rates as low as, or lower than, those among nonmanual classes. Compared with Northern Europe, mortality differences in the United States were smaller (among men aged 30-44 years) or about as large (among men aged 45-64 years). CONCLUSIONS: The results underline the highly variable nature of socioeconomic inequalities in ischemic heart disease mortality. These inequalities appear to be highly sensitive to social gradients in behavioral risk factors. These risk factor gradients are determined by cultural as well as socioeconomic developments. http://repub.eur.nl/res/pub/9208/ 1999-01-01T00:00:00Z OBJECTIVES: This study compared differences in total and cause-specific mortality by educational level among women with those among men in 7 countries: the United States, Finland, Norway, Italy, the Czech Republic, Hungary, and Estonia. METHODS: National data were obtained for the period ca. 1980 to ca. 1990. Age-adjusted rate ratios comparing a broad lower-educational group with a broad upper-educational group were calculated with Poisson regression analysis. RESULTS: Total mortality rate ratios among women ranged from 1.09 in the Czech Republic to 1.31 in the United States and Estonia. Higher mortality rates among lower-educated women were found for most causes of death, but not for neoplasms. Relative inequalities in total mortality tended to be smaller among women than among men. In the United States and Western Europe, but not in Central and Eastern Europe, this sex difference was largely due to differences between women and men in cause-of-death pattern. For specific causes of death, inequalities are usually larger among men. CONCLUSIONS: Further study of the interaction between socioeconomic factors, sex, and mortality may provide important clues to the explanation of inequalities in health. http://repub.eur.nl/res/pub/8825/ 1998-01-01T00:00:00Z OBJECTIVES: To compare countries in western Europe with respect to class differences in mortality from specific causes of death and to assess the contributions these causes make to class differences in total mortality. DESIGN: Comparison of cause of death in manual and non-manual classes, using data on mortality from national studies. SETTING: Eleven western European countries in the period 1980-9. SUBJECTS: Men aged 45-59 years at death. RESULTS: A north-south gradient was observed: mortality from ischaemic heart disease was strongly related to occupational class in England and Wales, Ireland, Finland, Sweden, Norway, and Denmark, but not in France, Switzerland, and Mediterranean countries. In the latter countries, cancers other than lung cancer and gastrointestinal diseases made a large contribution to class differences in total mortality. Inequalities in lung cancer, cerebrovascular disease, and external causes of death also varied greatly between countries. CONCLUSIONS: These variations in cause specific mortality indicate large differences between countries in the contribution that disease specific risk factors like smoking and alcohol consumption make to socioeconomic inequalities in mortality. The mortality advantage of people in higher occupational classes is independent of the precise diseases and risk factors involved. http://repub.eur.nl/res/pub/8928/ 1998-01-01T00:00:00Z BACKGROUND AND PURPOSE: Several studies observed that people from lower socioeconomic groups have higher chances of dying of stroke. There are reasons to expect that these differences are relatively small in southern European countries or in Nordic welfare states. This report therefore presents an international overview of socioeconomic differences in stroke mortality. METHODS: Unpublished data on mortality by occupational class were obtained from national longitudinal studies or cross-sectional studies. The data refer to deaths among men aged 30 to 64 years in the 1980s. A common occupational class scheme was applied to most countries. The mortality difference between manual classes and nonmanual classes was measured in relative terms (by rate ratios) and in absolute terms (by rate differences). RESULTS: In all countries, manual classes had higher stroke mortality rates than nonmanual classes. This difference was relatively large in England and Wales, Ireland, and Finland and relatively small in Sweden, Norway, Denmark, Italy, and Spain. Differences were intermediate in the United States, France, and Switzerland. In Portugal, mortality differences were intermediate in relative terms but large in absolute terms. In most countries, inequalities were much larger for stroke mortality than for ischemic heart disease mortality. CONCLUSIONS: Socioeconomic differences in stroke mortality are a problem common to all countries studied. There are probably large variations, however, in the contribution that different risk factors, such as tobacco and alcohol consumption, make to the stroke mortality excess of lower socioeconomic groups. Medical services can contribute to reducing socioeconomic differences in stroke mortality. http://repub.eur.nl/res/pub/8573/ 1994-01-01T00:00:00Z OBJECTIVES. The purpose of this study was to compare temperature and two windchill indices with respect to the strength of their association with daily variation in mortality in the Netherlands during 1979 to 1987. The two windchill indices were those developed by Siple and Passel and by Steadman. METHODS. Daily numbers of cause-specific deaths were related to the meteorological variables by means of Poisson regression with control for influenza incidence. Lag times were taken into account. RESULTS. Daily variation in mortality, especially mortality from heart disease, was more strongly related to the Steadman windchill index than to temperature or the Siple and Passel index (34.9%, 31.2%, and 31.5%, respectively, of mortality variation explained). The strongest relation was found with daytime values of the Steadman index. CONCLUSIONS. In areas where spells of cold are frequently accompanied by strong wind, the use of the Steadman index probably adds much to the identification of weather conditions involving an increased risk of death. The results of this study provide no justification for the wide-spread use (e.g., in the United States) of the Siple and Passel index.
