Incidence and disease burden of acute gastroenteritis among residents in Heilongjiang province, 2018

Abstract

ObjectiveTo estimate the incidence and burden of acute gastroenteritis among residents in Heilongjiang province, and to provide evidence for developing strategies on food-borne disease prevention and control. MethodsThe data on residents′ acute gastroenteritis incidence during 2018 were collected from community population surveys and hospital-based foodborne disease surveillance in Heilongjiang province and a pyramid model of disease burden was constructed to estimate total number of acute gastroenteritis cases in the province. The health burden of acute gastroenteritis was measured with disability adjusted life years (DALYs).ResultsFor whole population of the province in 2018, the estimated number of acute gastroenteritis cases was 133 814 (95% confidence interval [95%CI]: 105 635 – 169 334); the monthly prevalence was 3.54% (95%CI: 3.28% – 3.80%); and the incidence was 0.470/person year. The DALYs due to acute gastroenteritis was 11 320.40 (95%CI: 9239.09 – 13947.73) and the DALYs rate of the disease was 0.30 (95%CI: 0.25 – 0.37)/1 000 population, with the highest DALYs rate for the residents aged < 5 years (0.526 [95%CI: 0.24 – 1.41]/1 000 population) and the residents aged ≥ 60 years (0.680 [95%CI: 0.49 – 0.96]/1 000 population), respectively. ConclusionThe incidence of acute gastroenteritis was high among residents of Heilongjiang province, especially among the children under 5 years and the elderly over 60 years.
