Life Course Changes in Smoking by Gender and Education: A Cohort Comparison Across France and the United States

Widening of educational disparities and a narrowing female advantage in mortality stem in good part from disparities in smoking. The changes in smoking and mortality disparities across cohorts and countries have been explained by an epidemic model of cigarette use but are also related to life course changes. To better describe and understand changing disparities over the life course, we compare age patterns of smoking in three cohorts and two nations (France and the US) using smoking history measures from the 2010 French health barometer (N = 20,940) and the 2010 US National Health Interview Survey Sample Adult File (N = 20,444). The results demonstrate statistically significant widening of gender and educational differences from adolescence to early and middle adulthood, thus accentuating the disparities already emerging during adolescence. In addition, the widening disparities over the life course have been changing across cohorts: age differences in educational disparities have grown in recent cohorts (especially in France), while age differences in gender disparities have narrowed. The findings highlight the multiple sources of inequality in smoking and health in high-income nations.     

Cohort size and age-specific suicide rates: A contingent relationship

Trends in age-specific suicide rates relate to debates about the consequences of population aging and changes in cohort size for social well-being. Easterlin argues that large cohort size increases suicide rates by reducing relative income; Preston claims that suicide rates fall in large cohorts with high levels of political and social power. To integrate these competing arguments, this paper uses aggregate data on 18 high-income nations from 1953 to 1986 to demonstrate that the direction and strength of the relationship between cohort size and suicide depend on (1) age of the cohort, (2) gender, (3) national context, and (4) time period. The results show that large cohort size raises suicide for the young and middle-aged, but reduces it for the elderly. Also, the effects of cohort size prove stronger for men than for women, for nations with less collectivist institutions than for nations with more collectivist institutions, and for the 1950s and 1960s than for the 1970s and 1980s.     

Cohort Changes in the Socio-demographic Determinants of Gender Egalitarianism

Arguments about the spread of gender egalitarian values through the population highlight several sources of change. First, structural arguments point to increases in the proportion of women with high education, jobs with good pay, commitment to careers outside the family, and direct interests in gender equality. Second, value shift arguments contend that gender norms change with social and economic development among women and men in diverse positions - traditional and non-traditional alike. Third, diffusion arguments suggest that structural change leads to adoption of new ideas and values supportive of gender equality by non-traditional and innovative groups in society, but that the new ideas later diffuse to other groups through cultural processes. Using the General Social Survey from 1977 to 2006 and comparing the determinants of gender egalitarianism across 86 cohorts born from roughly 1900 through 1985, multilevel models support the diffusion arguments.     

Female labour force activity and the sex differential in mortality: Comparisons across developed nations, 1950–1980

In this paper, we examine the macro-level relationship between female labour force activity and the sex differential in mortality among developed nations. Discrimination, protection, and null relationship hypotheses are tested using aggregate data for 18 high income nations over seven time points from 1950 to 1980. High levels of female labour force activity — controlling for a variety of general social conditions — increase the longevity advantage women have over men. In some models the effects are immediate; in other models the effects occur after a substantial lag; but in no cases are there harmful effects for women's longevity. Also important for the differential are consumption of cigarettes and alcohol, and the level of income inequality in a society.     

Population Composition,Public Policy,and the Genetics of Smoking

In this article, we explore the effect of public policy on the extent to which genes influence smoking desistance. Using a sample of adult twins (n _mz = 363, n _dz = 233) from a large population registry, we estimate Cox proportional hazards models that describe similarity in the timing of smoking desistance among adult twin pairs. We show that identical twin pairs are significantly more likely to quit smoking within a similar time frame compared with fraternal twin pairs. Importantly, we then show that genetic factors for smoking desistance increase in importance following restrictive legislation on smoking behaviors that occurred in the early and mid-1970s. These findings support the social push perspective and make important contributions to the social demography and genetic epidemiology of smoking as well as to the gene-environment interaction literatures.     

Gender equality and the sex differential in mortality from accidents in high income nations

Despite their neglect by researchers relative to other causes of death, motor vehicle and other accidents contribute substantially to sex differences in mortality and address theoretical debates over the consequences of gender equality. A reduction-in-protection hypothesis argues that gender equality reduces the female advantage in accident mortality, a reduction-in-inequality hypothesis argues that gender equality increases the advantage, and an institutional adjustment hypothesis argues that gender equality initially reduces and then increases the advantage. The analysis tests these hypotheses using data on age-specific male and female accident mortality rates and indicators of work and family status for 18 high income nations from 1955–1994.In support of the institutional adjustment hypothesis, declining differentials in male and female motor vehicle and other accident mortality rates level off and sometimes increase in recent years, and measures of work and family change generally have similar curvilinear influences on the differential. Across nations, gender equality speeds the reversal in the differential for motor vehicle accidents, but not for other accidents.
