There are major differences between the sexes in morbidity and mortality rates. At all ages males have higher death rates and are more frequently afflicted with the chronic diseases associated with considerable reductions in longevity. Trend data indicate that males have become relatively more disadvantaged during a period characterized by major advances in medicine and increased access to care. ⋯ There is some evidence that these differences are associated more with behavioral than with biologic factors. Certain shifts in age-specific mortality rates reflect sex-role-related changes in behavior--e.g., increased consumption of tobacco by women and a reversal in sex mortality ratio for cancer of the lung. Changes in sex roles may affect directly, or indirectly through family dynamics, the health status of both sexes.

The general death rate rises during business booms and falls during depressions. The causes of death involved in this variation range from infectious diseases through accidents to heart disease, cancer, and cirrhosis of the liver, and include the great majority of all causes of death. ⋯ In twentieth-century cycles, the role of social stress is probably predominant. Overwork and fragmentation of community through migration are two important sources of stress which rise with the boom, and they are demonstrably related to the causes of death which show this variation.
