Chronic diseases, including cardiovascular diseases (CVD) and cancers, are leading causes of death worldwide. While Switzerland has experienced a regular decrease in mortality due to chronic diseases, the COVID-19 pandemic may have disrupted these trends. Our primary goal is to analyze trends of chronic disease mortality rates from 1995 to 2021 across different socioeconomic strata, using multiple causes of death data and analyzing the impact of the 2020 COVID-19 pandemic. We will conduct a multiple causes of death (MC) analysis, extending beyond the conventional method of identifying a single underlying cause, through a population-based analysis of all deaths in Switzerland during the study period, using data from the Swiss Federal Statistical Office's mortality statistics database. Causes of death will be identified via the ICD-10 coding system. Socioeconomic position will be assessed using the last known occupation. We will compute age-standardized yearly mortality rates and run segmented regression as well as interrupted time series analysis. Anticipated findings are expected to uncover changes in socioeconomic inequalities in mortality, providing invaluable insights for public health policy adjustments and underscoring the significance of MC data for more comprehensive mortality trend tracking.
