ABSTRACT
Objective To evaluate the effect of ambient temperature on the activity influenza like illness (ILI) and laboratory-confirmed influenza (LAB) in Wuxi City. Methods Daily data of meteorological, ILI and detected influenza virus from 31 December 2012 to 31 December 2017 were collected. Distributed lag non-linear model (DLNM) was used to evaluate the exposure-lag-response of ILI and LAB activity to daily ambient temperature.Results During the period, the overall ILI% was 4.96% and influenza detection positive rate was 12.28% in Wuxi city. The overall cumulative association analysis suggested non-linear relationship between ambient temperature and influenza: U-shaped for ILI, while L-shaped relationship for LAB. Low temperature (＜10℃ ) had strong and longer delay effect than hightemperature (＞20℃ ) for ILI. The cold effect for LAB was stronger and longer delay，and the low temperature (＜10℃ ) was risk factor for LAB. Conclusions The ambient temperature significant correlates with ILI and LAB, and low temperature might be risk factor with lag effect.
ABSTRACT
Objective To investigate cancer high - risk rate,screening rate,detection rate in Zhejiang urban area and to provide the further evidence for cancer screening,early detection and treatment programs. Methods Epidemiological investigation and cancer risk evaluation were launched among 40 - 69 years old residents in Hangzhou and Ningbo city. People who were at high risk of lung cancer,liver cancer,upper digestive tract cancer,female breast cancer and colorectal cancer could receive clinical screening for free. Cancer high risk rates,screening rate and clinical detection rates were calculated. Results A total of 41 547 residents finished questionnaires and cancer risk evaluation. Cancer high risk rates of lung,liver,upper digestive,female breast and colorectal were 14. 05% ,12. 58% ,23. 28% ,11. 50% and 11. 82% , respectively. The rates of people who encountered single,couple,three,four and five types of cancer high risk were 29. 64% ,10. 97% ,3. 41% ,1. 16% ,0. 38% ,respectively. Screening rates for the five types of cancer were 50. 91% for lung cancer,49. 16% for liver cancer,19. 55% for upper digestive tract cancer,56. 25% for female breast cancer and 21. 75% for colorectal cancer. Lung cancer/ suspected lung cancer detection rate was 2. 42% . Breast cancer screening BI- RADS Grade 4 - 5 detection rate was 6. 71% . Upper digestive tract cancer detection rate was 0. 32% . Liver cancer detection rate was 0. 04% . Colorectal cancer detection rate was 0. 75% . Conclusion Technical solutions and program management should be improved to enhance the effect of cancer screening,early detection and treatment programs.
