[Diet quality and mortality in elderly people living in Warsaw Region].
The aim of this study was to examine the relationship between indicators of diet quality and all-cause mortality in a group of elderly people. 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. Quality of diet was evaluated using following indicators: Greek Mediterranean Diet Score (GMDS), Mediterranean Diet Score (MDS), Healthy Diet Indicator (HDI), Healthy Eating Index (HEI), Diet Quality Index (DQI), and Diet Quality Index-Revised (DQI-R). Among men there were not significant relationships between all-cause mortality and diet quality measured by the indicators. While the risk of all-cause mortality was statistically significantly lower in women with lower HDI (RR = 0.61; 95% CI: 0.37-0.99) and DQI-R (RR = 0.60; 95% CI: 0.37-0.96) compared to women with higher quality of diet. A similar tendency was shown for MDS indicator (RR = 0.65; 95% CI: 0.40-1.05). It was concluded that indicators used to assessment of diet quality were not good predictors of mortality in Polish population. Therefore to continue study in this field it is necessary to create new diet quality indicator more suitable to nutritional habits in Poland.
