RESUMEN
Objective@#To explore incidence trend of hepatitis C in Chifeng City, Inner Mongolia Autonomous Region from 2008 to 2022, so as to provide the basis for formulating prevention and control measures for hepatitis C.@*Methods@#Data of reported hepatitis C cases in Chifeng City from 2008 to 2022 was collected through the Infectious Disease Information Reporting Management System. Trends in incidence of hepatitis C were analyzed using annual percent change (APC) and average annual percent change (AAPC). Impact of age, period and birth cohort on the risk of developing hepatitis C were analyzed by an age-period-cohort model.@*Results@#The annual average reported incidence rate of hepatitis C in Chifeng City was 59.13/105 from 2008 to 2022. The incidence showed an upward trend from 2008 to 2018 (APC=9.405%, P<0.05) and a downward trend from 2018 to 2022 (APC=-17.475%, P<0.05), but the overall trend was not statistically significant (AAPC=0.937%, P>0.05). The age-period-cohort model analysis showed that the incidence risks of hepatitis C in the residents aged 0 to 4 years and 45 to 84 years were higher than those in the residents aged 40 to 44 years (the control group). The incidence risk of hepatitis C increased with age from 40 to 79 years. Compared with 2008-2012, the incidence risk of hepatitis C showed an increasing trend followed by a decline in 2008-2022. The incidence risk was higher in 2013-2017 and lower in 2018-2022 than in 2008-2012. The incidence risk of hepatitis C showed an increasing trend followed by a decreasing trend by using the birth cohort from 1968 to 1972 as the control. The birth cohort from 1953 to 1977 had a higher incidence risk of hepatitis C than other birth cohorts.@*Conclusions@#The overall incidence of hepatitis C in Chifeng City from 2008 to 2022 appeared a tendency towards a decline, and the incidence risk increased with age. Screening and health education for the elderly and high-risk birth cohorts should be strengthened.
RESUMEN
Objective@#To understand the current status and influencing factors of anti-drug ability of college students in Beijing, and provide suggestions for drug education in universities.@*Methods@#A total of 966 students from 11 universities in Beijing were investigated with a self-designed questionnaire. and the data was analyzed with quantitative statistical analysis method.@*Results@#The average types of drug college students are aware of was 6.64. Among the average cognitive drugs of college students in Beijing,the full score rate of drug resistance was 68.12%. Gender, different majors, and frequency of receiving drug prevention education were influential factors of drug knowledge and anti-drug ability of college students (χ 2=41.38，18.20，11.02，P<0.05). The commonest educational method was themed lectures (80.33%), and the Internet had played an increasingly important role in education (76.60%). Anti-drug short-movies was the most interesting education method for college students (79.30%), with a penetration rate of 42.44%. The number of drugs awared and the ability of anti-drugs improved significantly through the "6.27" project.@*Conclusion@#The anti-drug propaganda and education should be strengthened among the students majoring in sport arts, and the function of anti-drug videos should be greatly exploited to maximize the effect of education.
