[Influence of chosen lifestyle and diet factors on mortality among elderly people living in Warsaw and surrounding villages].

The aim of this study was to examine the relationship between lifestyle factors, nutrients intake and all-cause mortality in a chosen group of elderly participants. The study was carried out among 411 participants aged 75-80 years (190 men and 221 women). During this study 78 men (42%) and 79 women (36.6%) died. In men higher risk of death (by 147%) was observed among participants with lower physical activity and intake of saturated fatty acid below median (32.7 g/d). In women higher risk of death was observed among participants with lower level of education (by 109%), lower physical activity (by 96%), smoking (by 336%), supplement used (by 56%), intake of protein below median (74.7 g/d), intake of dietary fiber above median (18.3 g/d) and intake of phosphorus above median (1167 mg/d). Research on survival set one direction for future studies in the field of nutritional epidemiology. Development of this part of science about nutrition in Poland may help to establish specific for elderly people directions for nutrition improving.
