Hugh Pickens writes writes: "Louise Radnofsky reports that a study by the National Research Council and Institute of Medicine has found US life expectancy near the bottom of 17 affluent countries with the US at or near the bottom in nine key areas of health: infant mortality and low birth weight; injuries and homicides; teenage pregnancies and sexually transmitted infections; prevalence of HIV and AIDS; drug-related deaths; obesity and diabetes; heart disease; chronic lung disease; and disability. Americans fare worse than people in other countries even when the analysis is limited to non-Hispanic whites and people with relatively high incomes and health insurance, nonsmokers, or people who are not obese. The report notes that average life expectancy for American men, at 75.6 years, was the lowest among the 17 countries and almost four years shorter than for Switzerland, the best-performing nation while American women's average life expectancy, 80.8 years, the second-lowest among the countries and five years shorter than Japan's, which had the highest expectancy. "The [U.S.] health disadvantage is pervasive—it affects all age groups up to age 75 and is observed for multiple diseases, biological and behavioral risk factors, and injuries," say the report's authors. The authors offered a range of possible explanations for Americans' worse health and mortality, including social inequality, limited availability of contraception for teenagers, community designs that discourage physical activity such as walking, air pollution as well as individual behaviors such as high calorie consumption. The report's authors were particularly critical of the availability of guns. "One behavior that probably explains the excess lethality of violence and unintentional injuries in the United States is the widespread possession of firearms and the common practice of storing them (often unlocked) at home," reads the report. "The statistics are dramatic.""
