We examined this association in Chinese adults using data from the China Kadoorie Biobank study. METHODS AND RESULTS Over 0.5 million adults aged 30 to 79 years were followed from baseline interview (2004-2008) until December 31, 2013. Past year MD was ...
BACKGROUND The burden of cardiovascular diseases (CVDs) is much more pronounced in Eastern Europe, a spatial gradient within Europe still exists. However, former studies showed a significantly lower CVD mortality of German repatriates from the Former Soviet Union compared with the German population. METHODS All-cause, CVD and ischemic heart disease (IHD) standardized mortality ratio (SMR), IH...
