Trends in the Stroke Death Rate among Mississippi Adults, 2000–2016

Introduction On average, more than 1,700 people in Mississippi die from stroke annually, but data on trends by age, sex, and race in Mississippi are limited. We examined trends in the stroke death rate among adults in Mississippi aged 35 or older by age, sex, and race. Methods We used Mississippi Vital Statistics data to calculate age-specific death rates for stroke among people in Mississippi aged 35 or older from 2000 to 2016. We identified cases according to underlying cause-of-death codes from the International Classification of Diseases, Tenth Revision (ICD-10). We used Joinpoint software to calculate annual percentage change (APC) and the average annual percentage change (AAPC) in death rates for stroke by age, sex, and race (non-Hispanic black and non-Hispanic white). Results Among adults aged 35 or older, the age-adjusted stroke death rate declined 30.7% from 141.3 per 100,000 population in 2000 to 97.9 per 100,000 population in 2016, with an AAPC of -2.4% (95% confidence interval, -3.1% to -1.6%). Stroke death rates declined significantly among both men and women in the first trend segment (2000-2009 for men and 2000-2007 for women) but did not decline in the second trend segment (2009-2016 for men and 2007-2016 for women). Non-Hispanic black men had the smallest decline in stroke death rates during the full study period. Among people aged 55 to 64 and non-Hispanic white men, rates shifted from a significant annual decline during the first segment to a significant annual increase during the second segment. Conclusion Age-adjusted stroke death rates among adults in Mississippi aged 35 or older declined significantly between 2000 and 2016, but trends differed by age, race, and sex. Clinical and community interventions aimed at reducing stroke risk factors, particularly for adults aged 55 to 64, are needed in Mississippi.
