Abstract:
Objective To investigate the epidemiological characteristics and spatial distribution of hepatitis B in children in Kaizhou District of Chongqing from 2018 to 2019, and to provide a theoretical basis for the prevention and control of hepatitis B. Methods The prevalence of hepatitis B in Kaizhou District of Chongqing from 2018 to 2019 was calculated using Excel2003, and the spatial data was processed by SaTScan9.6. Aggregation of incidence of hepatitis B was investigated by calculating Moran's I coefficient. Aggregated distribution of the incidence of hepatitis B was explored by local spatial autocorrelation analysis. Results From 2018 to 2019, the cumulative number of hepatitis B in children in Kaizhou District of Chongqing was 86, with an average annual reported incidence rate of 3.01 per 100,000. Among 86 children with hepatitis B, 54 were male and 32 were female, with a male to female ratio of 1.69:1. The incidence rate of hepatitis B in 2019 was lower than that in 2018 ( P<0.05 ). The incidence rate of hepatitis B in males was higher than that in females in each year (P <0.05 ). The incidence rate of hepatitis B among children aged 10 to 14 years old was higher than that of any other age groups ( P<0.05 ). The hepatitis B incidence reported in Chongqing from 2018 to 2019 had spatial aggregation (Moran's I=0.4736, P<0.05; Moran's I=0.3915, P<0.05). The high-high (H-H) cluster areas of hepatitis B were mainly distributed in Maliu Township, Zishui Township, and Tianhe Town, while the low-low (L-L) cluster areas of hepatitis B were mainly distributed in Zhaojia Street and Changsha Town. Conclusion In 2018-2019, the incidence of hepatitis B among children in Kaizhou District, Chongqing City had a downward trend. The incidence of hepatitis B among males and children aged 10 to 14 years old was relatively high. There was a positive spatial autocorrelation of the incidence. The prevention and treatment of hepatitis B in high-risk population and hot spots should be strengthened.
