The way people rate their health determines their probability of survival in the following decades. Researchers from the Institute of Social and Preventive Medicine at the University of Zurich demonstrate that for ratings ranging from "excellent," "good," "fair" and "poor" to "very poor," the risk of mortality increases steadily -- independently of such known risk factors as smoking, low education levels or pre-existing diseases.Even taking education levels, marital status, tobacco-related strains, medical history, the use of medication, blood pressure and blood glucose into account, the correlation between self-rated health and mortality only weakened marginally. The difference in the risk of death between the best and the worst rating was still 1:2.9 in men and 1:1.5 in women. "Our results indicate that people who rate their state of health as excellent have attributes that improve and sustain their health," concludes specialist in preventive medicine David Fäh. "These might include a positive attitude, an optimistic outlook and a fundamental level of satisfaction with one's own life."
