The relationship between dietary fiber intake and the state of cognitive function in middle and old age in the population of high cardiovascular risk

Aim of the study was to investigate relationship between dietary fiber (DF) intake and state cognitive function (CF) in a population sample middle elderly age Novosibirsk. Material methods. The conducted on random from residents Novosibirsk ( n = 9360, men women 45–69 years old), examined as part international HAPIEE project. A subsample baseline (4684 subjects) people who make up lift general were for functions during 2nd survey 2006–2008. examination protocol included standardized neuropsychological testing (quantitative assessment memory function, semantic concentration attention) collecting data nutrition (DF intake). Assessment odds ratio (OR) carried out using binary logistics regression by quartiles nutrients. Results. According cross-sectional analysis, we revealed positive association CF indicators DF aged 45–69, while groups is not statistically different. Some gender features associated with have been established: presumably, influence speech activity more expressed than men. Previously identified evidence that education modifies level decline our population, apparently, also relates intake. Conclusions. high cardiovascular risk positively an increase all studied domains. Established relationships are instrumental identifying decline.
