Do all traditional risk factors associate same with mortality in senior population?

Abstract

Aim. To evaluate the impact of traditional risk factors (RF) to overall and cardiovascular mortality of the population ≤75 year old. Material and methods. The results are acquired in the prospective cohort study "Stress, ageing and health". Totally, 455 Moscovites assessed, age ≤75 y. o. The traditional RF were evaluated: arterial hypertension, smoking, obesity and dyslipidemia. The follow up on mortality lasted for 8 years. Totally, 239 deaths registered, of those 169 cardiovascular. Statistics was done with STATA 14.1. Results. After stratification by sex and age, with the mortality from all cases in the 75-79 y. o. cohort, only current smoking status associated significantly (p=0,0001), and with cardiovascular mortality - current smoking and abdominal obesity, with relative risks 2,91 and 1,92, respectively. Also, in the ≤80 y. o. group, there were no RF influencing significantly the mortality. Conclusion. Among all traditional RF, in the age strata 75-79 y. o., only current smoking associated significantly with the all-cause mortality, and with cardiovascular - also abdominal obesity. Among the persons of ≤80 y. o., traditional RF lose their impact for both all-cause and cardiovascular mortality.
