Abstract

BACKGROUND

Mapping time-structures is a burgeoning scientific field enriching the (P4) medicine models. Local evidence in Mediterranean populations is underinvestigated.

METHODS

The Censused stroke-related death events (D) in the largest East-Mediterranean port (Piraeus), during (1985-1989), when local population had diet (low fat/sugar, proteins and vegetables/fruits daily, and pure olive oil almost exclusively) and genetic homogeneity-later interrupted by the immigration into Greece in 1990; and Sunspot numbers were indexed by Wolf numbers (Rz) (1944-2004), and evaluated using Fast Fourier Analysis and Singular Spectrum Analysis in MATLAB.

RESULTS

D were turned with fluctuations >35% in Rz. A non-anthropogenic 6.8 days cycle was recognized.

CONCLUSIONS

This study may be taken into consideration in future public health planning and chronotherapy evaluations.
