Research Project
Full description We assessed if the gap in mortality between adults with and without diabetes has widened over time in US adults. This cohort study included 44,041 adults with diabetes from the US National Health Interview Survey between 1986 and 2009 linked to the National Mortality Index data up to 2011. Each participant with diabetes was matched to two participants without diabetes by age, sex, race, survey year, and region of residence (88,082 persons without diabetes). Mortality differences and hazard ratios were calculated for different time periods defined by three methods, according to 1) survey years with original follow-up durations, 2) follow-up calendar years, and 3) survey years with a fixed 3-year follow-up duration.
