Cerebral Vascular Accidents (CVA) Victims Conception and Birth Time-Links to Longevity, Lithuania, 1989-2013

Abstract

In year 2001 a paper in the ANAS considered links between month of birth and longevity. In the following years we published four papers related to “big killers” (cardiac and oncology) that showed some differences in birth months distribution of this group and studied by LA, NS Gavrilov’s centenarians. The aim of this study was to study conception and birth months of another modern “big killer”—cerebral stroke (CVA) that is taking a leading role among cardiovascular causes of death in the last decades. Methods: 130,120 deaths of both gender CVA victims in Lithuania at 1989-2013 were studied. In addition to birth month, the months of conception (9 months before birth) were studied. Our data were compared with results of centenarians (birth of LA, NS Gavrilov’s study and transformed by authors also their conception month). Results: The maximum of births were January, March and May for CVA victims, while the analogical conception maximum were in April, June, May and July. The similar data for centenarians were that maximal births were in November, September, October (LA, NS Gavrilov) and conception in December, January, February. These results are similar to data related to cardiac and oncology deaths published in our previous publications. Conclusion: The conception and birth month of victims of CVA is different of similar data obtained by centenarians study. Different environmental conditions at different parts of the year and solar cycle can play a role affecting the embryo at early stages of development, predisposing to some pathologies in coming years of life.
