Changes in inequalities of mortality by education level in Lithuania between 2001 and 2014

The aim of the study is to analyse the changes in inequalities of mortality by education level in Lithuania between 2001 and 2014.

This is a record-linked cohort study.

Information on deaths (in the population aged ≥30 years) from all causes and cardiovascular diseases, cancer, external causes and diseases of the digestive system was obtained from Statistics Lithuania. Mortality rates for these causes were calculated by the level of education per 100,000 person-years. Inequalities in mortality were assessed using a rate ratio and a relative index of inequality with 95% confidence intervals (CIs). Joinpoint regression analysis was used to assess inequality trends between 2001 and 2014.

During the study period, mortality from all causes and from cardiovascular diseases, cancer, external causes and diseases of the digestive system was statistically significantly higher in the group with less education for both men and women, with the exception for female mortality from cancer in 2001. The highest decline was observed in the inequalities of mortality from external causes, whereas a major increase was observed in the inequalities of mortality from diseases of the digestive system. A large increase in inequalities was observed in mortality from external causes for men (on average by 3.5% per year [95% CI = 2-5.1]), whereas, for women, the highest increase in inequalities was observed in mortality from diseases of the digestive system (on average by 3% per year [95% CI = 0.6-5.5]). The slowest increase in mortality inequalities was noted for cardiovascular diseases for both men (on average by 1.1% per year [95% CI = 0.4-1.9]) and women (on average by 0.8% per year [95% CI = 0.3-1.3]).

Between 2001 and 2014, the inequalities in mortality by level of education in Lithuania significantly increased in terms of mortality from all causes, cardiovascular diseases, cancer, external causes and diseases of the digestive system.
