Social class and male cancer mortality in New Zealand, 1984-7.

Social class differences in cancer mortality among New Zealand men aged 15-64 years are examined for the period 1984-7. Age-standardised rates are presented for all cancer deaths, and for 23 specific cancer sites. The strongest social class mortality gradients were found for cancers of the larynx, liver, buccal cavity/pharynx, oesophagus, lung and for soft tissue sarcoma. On the other hand, rectal cancer, malignant melanoma, colon cancer, brain/nervous system cancers, and multiple myeloma showed higher death rates for the more advantaged socioeconomic groups. Lung cancer accounted for 54.1% of the overall social class gradient, and the major smoking related cancers (these include buccal/pharynx, oesophagus, larynx, lung and bladder, although it should be stressed that not all cases of these cancers are caused by smoking) accounted for 77.6% of the overall gradient.

Social class, marriage, and fertility in schizophrenia.

The hypothesis is presented that the etiology of schizophrenia is neurodevelopmental: schizophrenia is a disorder occurring in extremely late maturers, whereas manic-depressive psychosis affects early maturers. This hypothesis is related to recent neurobiological findings and also to the following epidemiological and demographic topics covered by the author in her review of social class, marriage, and fertility in schizophrenia: Kretschmer's observations of body type differences between patients with schizophrenia and manic-depressive psychosis; trends in the incidence of schizophrenia and manic-depressive psychosis in industrialized versus developing economies; changing epidemiology of the subtypes of schizophrenia and of manic-depressive psychosis; sex differences in manic-depressive psychosis and schizophrenia; fertility and childlessness in schizophrenia; selection for marriage in schizophrenia; marriage patterns, inbreeding, and schizophrenia; social class, social mobility, and occupation in schizophrenia; social mobility and social selection; excess of schizophrenia in the lowest strata of society; social class, course, and outcome; and social stress and schizophrenia.

Social class: the missing link in U.S. health data.

National vital statistics in the United States are unique among those of advanced capitalist countries in reporting data only by race, sex, and age--not by class and income. This article reviews the limited U.S. data resources that may be used to document social class inequalities in health. Summarizing the strengths and weaknesses of the British approach to gathering data on social class and health, the authors discuss possible approaches to collecting data that could be feasible in the U.S. context. They argue that educational level is an insufficient marker for socioeconomic position and contend that appropriate measures must take into account not only individual but also household and neighborhood markers of social class. These additional types of social class data are especially important for accurately describing and understanding social class inequalities in health among women and across diverse racial/ethnic groups.

Social class variations in schoolchildren's self-reported outcome of the health dialogue with the school health nurse.

INTRODUCTION AND PURPOSE: School health services is an important element in many countries' health promotion activities but little is known about the pupils' acceptance and perception of these services and their effects. The objective of this paper was to examine the pupils' self-reported outcome of the health dialogue and to examine the effect of social class on this response controlled for the effect of other relevant social factors. MATERIAL AND METHODS: The study is a survey. The population were all pupils in the fifth, seventh and ninth grade (11, 13 and 15 years old) in a random sample of schools in Denmark, response rate 87%, n = 5205. Data were collected by questionnaires. RESULTS: The majority of the pupils had reflected about the content of the last health dialogue with the school health nurse (54%), had discussed the content with their mother (62%) and with friends (54%); 62% had followed the nurse's advice, 77% had made their own autonomous decisions based on the health dialogue, and 11% had returned to the nurse for further advice. Pupils from the lower social classes had more often followed the nurse's advice (OR = 1.16, 95% CI: 0.99-1.37) and returned to the nurse (OR = 1.46, 95% CI: 1.12-1.90). Pupils from the middle and lower social classes had more often made their own autonomous decisions (middle social classes: OR =1.23, 95% CI: 1.08-1.39, lower social classes: OR = 1.13, 95% CI: 0.95-1.34). CONCLUSION: Most pupils reported an outcome of the health dialogue with the school health nurse. Pupils from lower social classes seemed to benefit more than pupils from higher social classes.

Infection with Helicobacter pylori and parasites, social class and cancer.

Three genera of parasites are known or suspected risk factors for cancer in humans: Schistosoma, Opisthorchis and Clonorchis. No adequate information is available on the determinants of infections related to social class. Infection with the bacterium Helicobacter pylori is an important cause of stomach cancer. Studies, in particular from the United Kingdom and the United States of America, strongly suggest that social class factors, especially those acting during childhood, are determinants of the infection, with odds ratios of seroprevalence of the order of 1.5-5 for lower social class as compared with higher social class. A conservative estimate of the contribution of social class, acting through an increased prevalence of H. pylori infection, to the burden of stomach cancer gives a figure of over 50,000 stomach cancers per year worldwide, or 8% of all stomach cancers. In countries with both high and low prevalence of infection with H. pylori, it is likely that a sizeable proportion of this difference is due to social-class-related risk factors of infection.

Social class and premature mortality among men: a method for state-based surveillance.

OBJECTIVES: This study examined trends in mortality by social class for Black and White men aged 35 through 54 years in North Carolina, for 1984 through 1993, using an inexpensive, newly developed state-based surveillance method. METHODS: Data from death certificates and census files permitted examination of four social classes, defined on the basis of occupation. RESULTS: Premature mortality was inversely associated with social class for both Blacks and Whites. Blacks were at least twice as likely to die as Whites within each social class. CONCLUSIONS: Adoption of state-specific surveillance of social class and premature mortality would provide data crucial for developing and evaluating public health programs to reduce social inequalities in health.

The effect of social class and cognitive orientation on clinical expectations.

Therapists have been found to have more favourable expectations of clients from similar social class backgrounds than of clients from dissimilar social class origins. This relationship is unlikely to be simple. Cognitive variables most probably function as mediators between social class and expectations about therapeutic benefit. In particular, it was hypothesized that the variable, locus of control, would mediate therapists' clinical expectations. Two studies, involving clinical psychologists, tested this prediction. Therapists were asked to estimate their likely success with clients presented in the form of vignettes and role plays. The vignettes and role plays depicted the social class and locus of control of clients. Results indicate that there was a significant interaction between client's and therapist's locus of control in relation to therapists' judgements of therapeutic success.

Social class, admixture, and skin color variation in Mexican-Americans and Anglo-Americans living in San Antonio, Texas.

Social class may act in different ways as a barrier to gene flow in urban populations, depending on ethnicity. We test the hypothesis that biological variation is affected by social class subdivision using skin reflectance data collected for 393 Anglo-American and 930 Mexican-American adults in the major urban population of San Antonio, Texas. Two socioeconomic groups were sampled for the Anglo-American population: a middle-income transitional group and a high-income suburban group. In addition, we sampled a third socioeconomic group for Mexican-Americans: a low income barrio. Sex and age effects on skin color are minimal. Social class has no effect on skin color variation for Anglo-Americans, whereas there is a highly significant effect on social class subdivision for Mexican-Americans. Admixture estimates were derived from skin reflectance data and show that the proportion of native American ancestry decreases as social class increases.

Social space, social class and Bourdieu: health inequalities in British Columbia, Canada.

This article adopts Pierre Bourdieu's cultural-structuralist approach to conceptualizing and identifying social classes in social space and seeks to identify health effects of class in one Canadian province. Utilizing data from an original questionnaire survey of randomly selected adults from 25 communities in British Columbia, social (class) groupings defined by cultural tastes and dispositions, lifestyle practices, social background, educational capital, economic capital, social capital and occupational categories are presented in visual mappings of social space constructed by use of exploratory multiple correspondence analysis techniques. Indicators of physical and mental health are then situated within this social space, enabling speculations pertaining to health effects of social class in British Columbia.

The health impact of smoking in manual and non-manual social class men and women: a test of the Blaxter hypothesis.

Blaxter has hypothesized that harmful behavioral habits like smoking have a greater impact on health in the non-manual than in the manual social classes, possibly because other adverse exposures have a more important role in the manual social classes. However, the outcome measure used was a composite measure of physiological indices of morbidity and the relevance of this to other health problems is uncertain. We have therefore investigated the effect of smoking on mortality, to test whether the risk of death associated with smoking differs between manual and non-manual social classes. Data on 6831 men and 7993 women, aged 45-64 when screened in the Renfrew and Paisley study, a large prospective observational study in the West of Scotland, have been analyzed. All cause mortality rate ratios for smokers compared with never smokers have been calculated within manual and non-manual social classes. Although the age adjusted rate ratios are slightly higher among the non-manual men and women (2.19 [1.83-2.61] versus 1.92 [1.71-2.17] for non-manual and manual men respectively, and 1.75 [1.54-1.99] versus 1.65 [1.50-1.82] for non-manual and manual women), this difference between social classes is not statistically significant (p-values for test of difference 0.26 and 0.47 for men and women respectively). When additionally adjusted for other risk factors, cardiorespiratory symptoms and deprivation, this picture remained the same (p-values for test of difference are 0.41 and 0.50 for men and women respectively). Similar results were found when the cohort was divided by deprivation categories rather than social classes or when smoking related mortality rather than mortality from all causes was used as the outcome measure. We therefore conclude that the health impact of smoking is similar in each socio-economic group. The relative health improvement consequent on smoking cessation is thus similar in different socio-economic groups.

Mortality among the elderly in Sweden by social class.

Total mortality has been analysed for elderly Swedish men and women by social class. Information on social and demographic factors was obtained from the 1960 Population Census. The mortality was followed up from 1961 to 1979. The study indicates that there are evident social class differences in mortality among people aged 65-83 years. We found increasing class differences with increased age among women, but decreasing class differences with increased age among men. Also, the class gradients before retirement age were steeper than after that age. The opposite was true for women, where the class gradient was more evident among older women than among younger ones. The class gradients were less marked for married than for other marital status groups and the class gradients were steepest in areas with a high degree of urbanization.

Effects of field-dependency, social class and sex of children between ages 5 and 10.

Development of field-independency has been studied as a function of age (5 to 10), social class, and sex utilizing two groups of 96 subjects each of high and low social class. On the Children's Embedded-figures Test a critical developmental period appears between ages 5 and 8 yr. for all Ss; on the Draw-a-Person such a period appears between ages 5 and 6 for high social class and between ages 6 and 8 for lower social class; scores on both tests were statistically significant as a function of social class at every age beginning at age 6. Sex did not seem to play any significant role. Three main masking factors have been singled out on the Children's Embedded-figures Test. Their differential effects on scores of Ss in the two classes are examined.

Physical function and social class among Swedish oldest old.

The relationship between physical ability and social class in later life was explored through an interview survey conducted on a nationally representative sample of persons aged 77-98 (N = 537). Physical ability was measured with activities of daily living, an index of mobility, and performance tests. Social class was measured according to previous occupation. Physical function was found to be correlated with social class, that is, former white-collar workers had better function than blue-collar workers. The differences were significant for all three measures of physical function.

Genetic and environmental influences on the relation between parental social class and mortality.

BACKGROUND: Genetic and maternal prenatal environmental factors as well as the post-natal rearing environment may contribute to the association between childhood socioeconomic circumstances and later mortality. In order to disentangle these influences, we studied all-cause and cause-specific mortality in a cohort of adoptees, in whom we estimated the effects of their biological and adoptive fathers' social classes as indicators of the genetic and/or prenatal environmental factors and the post-natal environment, respectively. METHODS: In all 12 608 children born 1924-47 in Denmark who were placed early in life with adoptive parents were followed up for causes of death until 2000. Hazard ratios for paternal social class retrieved from adoption records were estimated using Cox regression models. RESULTS: Adoptees with biological fathers from higher social classes had a lower rate of mortality after their fifth decade of life, mainly due to a lower risk of cardiovascular, infectious, and respiratory diseases. Adoptive father's social class showed no clear relation with adoptee's mortality risk. The risk estimates for paternal social class were slightly attenuated after adjustment for adoptee's adult social class, which as expected was inversely related to mortality from both natural and external causes. CONCLUSION: Genetic and/or prenatal environmental factors contribute to the development of the relation of paternal social class to mortality from natural causes later in adult life independently of the effect of own social class, whereas there is no evidence for such long-term effect of the rearing environment.

The relationship between fluoridation, social class and caries experience in 5-year-old children in Newcastle and Northumberland in 1987.

The dental health of 457 5-year-old children who have lived continuously in fluoridated (at 1.0 mg F/litre) Newcastle and 370 children of the same age in non-fluoridated (less than 0.1 mg F/litre) South Northumberland has been reported. This paper examines in detail the caries prevalence in social class groups I + II, III, IV + V, and the social class/fluoridation relationship in 1987. The prevalence of dental caries in the three social class groupings I + II, III, and IV + V (and the mean dmft), respectively, was 35% (1.1), 46% (1.7) and 67% (2.4) in the fluoridated area, and 59% (2.2), 67% (3.7) and 77% (5.0) in the non-fluoridated area. Fluoridation was effective in all social class groupings and, because caries levels were higher in social classes IV + V, fluoridation brought about greater savings for these children than for those in social classes I + II. Fluoridation reduces but does not eliminate social inequalities, leaving social disadvantage/social background/social class as the major factors in caries prevalence for this age group. Further research into the fluoridation/social class relationship is required, particularly since the understanding of occupational class, now considered an imperfect representation of social class, is being superseded by other criteria which have stronger associations with measures of poor health.

Social class inequalities in perinatal outcomes: Scotland 1980-2000.

OBJECTIVE: To examine social class inequalities in adverse perinatal events in Scotland between 1980 and 2000 and how these were influenced by other maternal risk factors. DESIGN: Population based study using routine maternity discharge data. SETTING: Scotland. PARTICIPANTS: All women who gave birth to a live singleton baby in Scottish hospitals between 1980 and 2000 (n=1,282,172). MAIN OUTCOME MEASURES: Low birth weight (LBW), preterm birth, and small for gestational age (SGA). RESULTS: The distribution of social class changed over time, with the proportion of mothers with undetermined social class increasing from 3.9% in 1980-84 to 14.8% in 1995-2000. The relative index of inequality (RII) decreased during the 1980s for all outcomes. The RII then increased between the early and late 1990s (LBW from 2.09 (95%CI 1.97, 2.22) to 2.43 (2.29, 2.58), preterm from 1.52 (1.44, 1.61) to 1.75 (1.65, 1.86), and SGA from 2.28 (2.14, 2.42) to 2.49 (2.34, 2.66) respectively). Inequalities were greatest in married mothers, mothers aged over 35, mothers taller than 164 cm, and mothers with a parity of one or more. Inequalities were also greater by the end of the 1990s than at the start of the 1980s for women of parity one or more and for mothers who were not married. CONCLUSION: Despite decreasing during the 1980s, inequalities in adverse perinatal outcomes increased during the 1990s in all strata defined by maternal characteristics.

Social inequality and depressive disorders in Bahia, Brazil: interactions of gender, ethnicity, and social class.

We conducted a study of the association between gender, race/ethnicity, and social class and prevalence of depressive disorders in an urban sample (N = 2302) in Bahia, Brazil. Individual mental health status was assessed by the PSAD/QMPA scale. Family SES and head of household's schooling and occupation were taken as components for a 4-level social class scale. Race/ethnicity (white, moreno, mulatto, black) was assessed with a combination of self-designation and a system of racial classification. The overall 12-month prevalence of depressive symptoms was 12%, with a female:male ratio of 2:1. Divorced/widowed persons showed the highest prevalence and single the lowest. There was a negative correlation with education: the ratio college educated:illiterate was 4:1. This gradient was stronger for women than men. There was no F:M difference in depression among Whites, upper-middle classes, college-educated, or illiterate. Prevalence ratios for single, widowed and Blacks were well above the overall pattern. Regarding race/ethnicity, higher prevalences of depression were concentrated in the Moreno and Mulatto subgroups. There was a consistent social class and gender interaction, along all race/ethnicity strata. Three-way interaction analyses found strong gender effect for poor and working-class groups, for all race/ethnicity strata but Whites. Black poor yielded the strongest gender effect of all (up to nine-fold). We conclude that even in a highly unequal context such as Bahia, Blacks, Mulattos and women were protected from depression by placement into the local dominant classes; and that the social meaning of ethnic-gender-generation diversity varies with being unemployed or underemployed, poor or miserable, urban or rural, migrant or non-migrant.

Social class differences in child mortality, Sweden 1981-1986.

STUDY OBJECTIVE: The aim was to analyse social class differences in mortality among Swedish children, 1-19 years old, during the period 1981-86. In order to study the development of these differences, mortality differences during the study period were compared with those 20 years earlier, ie, 1961-66. DESIGN: The study used data from two census linked death registries (CDR80 and CDR60). These were constructed by linkages between the 1980 and 1960 population censuses, respectively, and the corresponding national cause of death registries. Age specific and age standardised death rates, for total and cause specific mortality, were calculated for each social class and for the genders separately. To compare the death rates of social classes, relative risks with approximately 95% confidence limits were calculated. STUDY POPULATION: The study included children younger than 16 years at the time of the censuses and all deaths in the age range 1-19 years. The children were followed up for a period of six years after the censuses with respect to mortality. MAIN RESULTS: During the period 1981-86, children in families of both manual workers and self employed persons had a significantly higher mortality than children in families of non-manual workers. CONCLUSIONS: Although there has been a marked decrease in child mortality during the last decades the study shows that social class differences in child mortality still exist and show little tendency to disappear.
