Objective To investigate the hygiene status and major problems in public places within the jurisdiction of Shanghai Railway Bureau, and assess associated determinants.
Methods Historical environmental servaillance data were collected on nine indicators(such as temperature and PM10) for station waiting rooms(n=6) and passenger trains(35 ordinary trains, 39 China Railway High-speed trains, and 15 high-speed rail trains). Key respondents(n=29) including monitoring staff from Center for Disease Control and Prevention of Shanghai Railway Bureau and health administrators in charge of hygiene of stations and trains were interviewed for this article to investigate the determinants of hygiene status in public places.
Results The hygiene qualified rate of station waiting rooms were over 89.01% in general, but showing a declining trend annually. Shanghai Hongqiao Station ranked the first with 98.94%, whereas Kunshan South Station ranked at bottom of the hygiene qualified rate of station waiting rooms with 80.00%. In addition, the qualified rates of temperature(65.29%) and noise(74.12%) were lower than the other indicators. The three-year qualified rate of passenger trains was 90.05%, but in a yearly declining trend. The selecet high-speed rail trains ranked first with 94.81%, whereas the China Railway High-speed trains was at bottom of the qualified rate of passenger trains with 87.22%. The qualified rate of temperature was the lowest(59.72%). The results from key respondent interviews showed the determinants of indoor air quality included setting up smoking areas and conducting integrated central air-conditioning monitoring and cleaning/disinfection.
Conclusion The findings indicate good hygiene status of the two types of public places in the jurisdiction of Shanghai Railway Bureau. The indicators reflecting existing problems are also consistent across selected public places.
