OBJECTIVE Prevalence of type 1 diabetes (T1D) disease is increasing worldwide. We aim to test correlation of T1D prevalence to the reduced natural selection measured by Biological State Index (Ibs). RESEARCH DESIGN AND METHODS Country-specific estimates of T1D prevalence, life expectancy, obesity prevalence rate, urbanization rates, per capita sugars consumption and per capita gross domestic p...

This study looked at the link connecting growth of economy and health spending in Central Eastern Sub-Saharan Africa. To assess short long-term effects total per capita expenditure on across African areas (East Africa Africa), panel data analysis was employed. In short-term, per-capita (THE_PC) has an upbeat outcome economic (LGDP_PC) all levels significance. long-term, current per-capital (CHE...

The primary risk-modifying factors for prostate cancer are still a matter of debate. This work proposes and examines the hypothesis that the apolipoprotein E epsilon4 (ApoE4) allele and diet are important risk factors for prostate cancer. The hypothesis was evaluated in an ecological study involving 122 countries for which prostate cancer rates for 2002, ApoE4 allele prevalence, dietary supply ...

Convergence hypothesis is one of the results of neoclassical growth model, which has been examined recently. This hypothesis has two forms of absolute and conditional Beta-convergence and implies that regions with lower per capita output have higher per capita growth rates. Since there is no data for regional GDP in Iran, there has been n study to test convergence hypothesis in Iran. Our main c...
