Influence of Demographic Factors on Standardised Rate Ratio of Age-adjusted Mortality Rates of Men in Comparison with Women Caused by Neoplasms and Circulatory System Diseases in Slovak Regions during 1996-2013

Abstract

Aim: The aim of our study was to find statistical associations including trends of standardised rate ratio of age-adjusted mortality rates for the male population as compared to the female population, in relation to available demographic factors (Chapter II - Neoplasms vs. Chapter IX - Diseases of the circulatory system, Slovak region and calendar year of death).

Methods: Dataset of individual cases of death in Slovakia with some demographic factors during 1996-2013 were provided by Slovak National Health Information Center. We used regression and correlation analyses, as well as analyses of variance and covariance along with descriptive statistics.

Results: The standardised rate ratio of age adjusted mortality rates of men versus age-adjusted mortality rates of women differs between Chapter II and Chapter IX (mean 2.08 vs. 1.35, p<0.001). There are also significant differences of standardised rate ratio among regions (p<0.05). Trends show that the standardised rate ratio has significant regional decline for Chapter II: Košice (p<0.01), Trenčín (p<0.001) and Žilina (p<0.05) whereas in Chapter IX Žilina region (p<0.01) is implicated. In other Slovak regions standardised rate ratio stagnates.

Conclusions: Standardised rate ratios of age-adjusted mortality rates for the male population compared to the female population are significantly dependent on chapter, sex and region. Standardised rate ratios either decline or stagnate.
