Survival in the oldest old: death risk factors in old and very old subjects.

Factors predicting death in the ninth decade of life may differ from predictors in younger age groups. A prospective study was carried out on 210 subjects entering a residential home at the age of 68 to 79 years and of 287 subjects aged greater than or equal to 80 years who included 91 survivors from the first group; all subjects were followed until 78% of them had died. A Cox analysis was carried out with death as end point and 13 potential risk factors as covariates.

Long-term prediction of coronary heart disease mortality in two rural Greek populations.

In 1960-61 two pooled Greek rural populations totalling 1215 men aged 40-59 years were followed-up for 25 years. A Cox model analysis of fatal coronary events over 15 years showed that serum cholesterol in men aged 40-59 years, cholesterol in men aged 45-64 years, and systolic blood pressure in men aged 50-69 played a predictive role. The coefficient of age became more significant with advancing age and that of cigarette smoking only at 25 years follow-up.

Short vs. long cotrimoxazole courses in eradicating bacteriuria in the elderly.

To test whether longer duration of treatment of asymptomatic bacteriuria in old age could improve the efficacy of cotrimoxazole therapy, three regimens were given to 75 ambulant bacteriuric residents of a retirement home, aged greater than or equal to 68 years. The groups and regimens were: A:23 subjects (160/800 mg b.i.

Survival in a residential home: an eleven-year longitudinal study.

The length of survival and various risk factors were studied utilizing 408 residents (141 men, 267 women) of a large residential home. The subjects, aged 68 years or more at entry, admitted between 1978 and 1983, were physically independent, continent, and non-diabetic. They were followed until December 31, 1988, by which time 78% had died.
