Influence of age, body mass index, smoking and alcohol intake on mortality in some regions of Croatia

We examined the effect of age, body mass index, number of smoked cigarettes a day, alcohol consumption and region on all-cause mortality by gender. The analyses were based on data from an epidemiological-longitudinal study started in 1969 with follow-ups in 1972 and 1982. We estimated survival functions by region using a life-table estimate. The city of Split had the best overall survival. The estimates of hazard ratio based on the Cox regression model with time dependent covariates indicated that age and smoking significantly increased the hazard of death. Mortality risk increased with low and high BMI (<Q1 and > Q3). Alcohol consumption did not significantly affect the hazard in our model. Women appeared more susceptible to the increased mortality risk of heavy drinking (RR=2.58).
