Abstract

Abstract:

Objective To analyze the cases of pulmonary tuberculosis reported in primary and middle school students, and understand the epidemic characteristics of this infection in the primary and middle school campus in Changsha City for evidence to formulate corresponding intervention measures in scientific fashion. Methods The case information of pulmonary tuberculosis among primary and secondary school students in Changsha from 2013 to 2022 was obtained through the Tuberculosis Management Information System of China Information System for Disease Control and Prevention. Descriptive method was used to analyze the prevalence characteristics in terms of time, regional and population distribution. Results In total, 1 167 cases of pulmonary tuberculosis were reported in primary and secondary school students in Changsha area from 2013 to 2022. The incidence reported annually was between 8.16 and 13.99 per 100 000, and the incidence showed increase from 2013 to 2019, yet decrease from 2019 to 2022. The difference was significant (χ²_trend=14.94, 21.00, both P<0.05). In the reported cases, 628 were males, and 539 females, with a sex ratio of 1.17∶1. The highest proportion of reported cases was seen in the age group of 15-18 years old (74.12%, 865/1 167). In terms of time distribution, the number of reported cases was mainly concentrated in between March and April, August and September, respectively accounting for 22.19% (259/1 167) and 24.68% (288/1 167) of the total reported cases. By regional distribution, Yuhua District had the highest proportion of reported cases (15.77%, 184/1 167), and the highest annual incidence was found in Tianxin District (15.91/100 000). Conclusion Primary and middle school students are one of the key population in pulmonary tuberculosis prevention and control in Changsha City in recent years, for which the prevention and control policies should be formulated by targeting at this population group.
