Mortality in an urban population in central Sweden in relation to mental disorder and alcohol consumption. A prospective study.

A representative selection of 2,283 individuals, 18-65 years old in "former" Stockholm County were called to examinations by psychiatrists during the period 1970-1971. During the period from the original examination to 1980, inclusive, a total of 114 examined persons (77 men, 37 women) had died. The relative death rate of those studied was 1.05 for men 0.90 for women (average for Sweden = 1). Women in social class III had a significantly higher relative death rate (1.23) compared with women in social class I (0.35). Those individuals who had a psychiatric diagnosis of moderate or severe degree had a significantly higher relative death rate (1.73) than those having a psychiatric diagnosis of mild degree (0.69). Men without psychiatric diagnosis had a significantly higher relative death rate (1.17) than men with a psychiatric diagnosis of mild degree (0.49). Individuals with high or very high alcohol consumption had a higher, although not statistically significant, relative death rate (1.69) compared with those with a low-moderate consumption (0.93).
