  1. Inequality in income and mortality in the United States : analysis of mortality and potential pathways.

    Article - En anglais


    To examine the relation between health outcomes and the equality with which income is distributed in the United States.

    Design-The degree of income inequality, defined as the percentage of total household income received by the less well off 50% of households, and changes in income inequality were calculated for the 50 states in 1980 and 1990.

    These measures were then examined in relation to all cause mortality adjusted for age for each state, age specific deaths, changes in mortalities, and other health outcomes and potential pathways for 1980,1990, and 1989-91.

    Main outcome measure-Age adjusted mortality from all causes.

    Result-There was a significant correlation (r=0.62, P<0.001) between the percentage of total household income received by the less well off 50% in each state and all cause mortality, unaffected by adjustment for state median incomes.

    Income inequality was also significantly associated with age specific mortalities and rates of low birth weight, homicide, violent crime, work disability, expenditures on medical care and police protection, smoking, and sedentary activity.

    Rates of unemployment, imprisonment, recipients of income assistance and food stamps, lack of medical insurance, and educational outcomes were also worse as income inequality increased.

    Income inequality was also associated with mortality trends, and there was a suggestion of an impact of inequality trends on mortality trends.

    Conclusion-Variations between states...
