[All-cause mortality among men of elderly and senile age depending on day of week, a season and changing to daylight saving time for a 13-year period].

To study the all-cause mortality among men of elderly and senile age depending on day of week, month of year, a season, changing to daylight saving time, prospective supervision over 1067 men of 60 years and upward for a 13-year period was conducted. The all-cause mortality depending on transition into daylight saving time was counted for March and October and compared to indicators of April and November accordingly. The all-cause mortality rate had made 1668,5 on 1000. This indicator in January (177.9 per 1000) and August (175.2 per 1000) was higher, than in November (102.4 per 1000; p < 0.05). Dependence of all-cause mortality rate on day of week, a season, changing to daylight saving time was not revealed. The analysis of all-cause mortality rate on days of week in various seasons has revealed that in autumn the greatest all-cause mortality rate was observed on Sunday (83.6 per 1000), the least--on Monday (35.0 per 1000). Besides, on Monday the greatest all-cause mortality rate was observed in winter (35.5%, or 72.8 per 1000), and the least one--in autumn (17.1%, or 35.0 per 1000). During other moments of supervision statically significant distinctions were not revealed.
