An analysis on the burden of stroke in Fenghua City / 预防医学

Objective The purpose of this study was to analyze the burden of stroke in Fenghua City by disability-adjusted life-years (DALYs).Methods We used data of stroke incidence,prevalence and mortality in Fenghua City in 2013 and selected DISMODII to calculate DALYs.Results There were 1 895 cases of stroke reported in 2013,and the reported incidence rate was 392.03/100 000(standard incidence rate was 201.14/100 000).The reported incidence rate among male 436.33/100 000 (standard incidence rate was 210.55/100 000 ),higher than that of female 346.48/100 000 (standard incidence rate was 189.25/100 000)(P<0.05).There were 751 cases of stroke death,and the mortality rate was 155.28/100 000(standard mortality rate was 66.53/100 000).The prevalence rate of stroke was 1 899.53/100 000, and people aged over 60 were accounted 85.53%.The overall disease burden of stroke was 7 566.03 DALYs,with the intensity of 15.64 DALYs per 1 000 population.Men had a higher DALYs and DALYs intensity than in women.The burden of residents aged over 60 was 84.75%.Years of life lost (YLL ) was the main fraction in DALYs,and its percentage was 76.75%.Conclusion The overall disease burden of stroke in Fenghua City was high,suggesting that the community should pay more attention to the men aged over 60 in order to reduce the burden of stroke.
