Longevity was significantly associated with season of birth in 101,634 individuals who died in Kiev during the period 1990-2000. Longevity values were lowest for subjects born in April-July, and highest for individuals born at the end of the year. Minimum and maximum longevity by month of birth differed by 2.6 years in men and 2.3 years in women. It is shown that the persons born in the fourth quarter, died from accidents or suicide less often, than those born in the second quarter. That can testify their better social adaptability. Age of death of the persons who have died from age-related diseases (neoplastic and circulatory) depend on a season (month) of birth to the greatest degree. The obtained results testify that the early (pre- and/or postnatal) seasonal factors influence on age-related mortality and longevity of the people.
