ABSTRACT

Objective:To determine the prevalence and risk factors of asthma among adults. Methods:A total of 37 670 adults aged 18 years and above was enrolled in Songjiang District, Shanghai using a multi-stage stratified sampling method between April 2016 and October 2017. Statistical analysis, such as t-test and Chi-square test, was performed to check the difference between the participants with asthma and non-asthma participants. Risk factors for asthma were examined by logistic regression analysis in all participants. Results:Overall, 36 698 subjects were enrolled in the study, in which 752 had asthma. The overall prevalence of asthma was determined to be 2.05%. The prevalence in females was 2.16%, and that in males was 1.88%, which didn’t achieve significance(P>0.05). Compared to non-asthma participants, those with asthma were more likely to be older ([60.3±9.48] years vs. [56.29±11.31] years), widowed (6.91%>4.45%,P<0.05), with educational level of primary school and below (58.64%>46.55%, P<0.01), higher level of total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) (P<0.05), had more co-morbidities, such as hypertension (42.00%>15.00%,P<0.001), chronic obstructive pulmonary disease (COPD) (6.25%>0.41%,P<0.001), chronic bronchitis (51.33%>6.32%,P<0.001) and tuberculosis (2.66%>0.96%,P<0.05), depression(2.13%>0.41%,P<0.05), and Parkinson's disease (0.93%>0.39%,P<0.05). Multivariable analysis showed that family history of asthma, history of hypertension, chronic bronchitis, COPD, depression and educational level of primary school and below were the risks factors associated with adult asthma (P<0.05). Conclusion:Prevalence of adult asthma in Shanghai has increased in recent years. Targeted health education may be strengthened for improving adult awareness towards asthma and reducing the disease burden.

ABSTRACT

Objective To determine the status of HIV/AIDS-related knowledge, attitude and behavior in college students, and to provide the theoretical basis for strategy of control and prevention. Methods By using random cluster sampling method, we conducted an anonymous online questionnaire survey on a total of 917 young students in Songjiang District of Shanghai. Results The awareness rate of HIV/AIDS-related knowledge was 71.8% among 903 responders. 11.1% of the students had sexual experience, and the rate was higher in male students than in female students(χ2 = 10.549, P < 0.01). The average age of first sexual intercourse was 18.4±1.3 years old, and 60.0% of the students used condom when having sex for the first time. In this survey, only 28.2% were willing to take anonymous HIV antibody urine test, and 1.8% of the students had been tested for HIV. Conclusion The overall awareness rate of knowledge of prevention and control of HIV/AIDS, the rate of condom use, and the willingness to take anonymous HIV antibody urine test are low among young college students in Songjiang District of Shanghai. We suggest to carry out targeted health education activities and to expand coverage of HIV testing by promoting the anonymous HIV antibody urine test for control the spread of HIV/AIDS among young students.

ABSTRACT

Objective To analyze the surveillance data after schistosomiasis transmission interruption from 1985 to 2018, so as to provide scientific basis for the future prevention and control of schistosomiasis. Methods The data pertaining to snail survey, surveillance of schistosomiasis in humans and livestock, and health education were collected and analyzed in Songjiang District after schistosomiasis transmission interruption from 1985 to 2018. Results From 1985 to 2018, there were 8 townships, 68 villages and 1 462 settings with snails in Songjiang District, covering an area of 96.399 hm2. There were 4 townships and 59 villages with snails newly identified in previously schistosomiasis non-endemic areas, with emerging snail habitats of 60.161 hm2. A total of 26 148 snails were captured, and no infections were detected. The snail habitats were mainly distributed in the river course, ditches and farmlands, which accounted for 45.28%, 33.17% and 21.55% of total snail habitats, respectively. A total of 245 955 humans were subjected to the serological test, with a positive rate of 0.03%, and 37 humans were subjected to the parasitological test, with 3 positives detected. These three egg-positives were all imported chronic cases with schistosomiasis. A total of 9 109 livestock were detected using the serological test, and no infection was found. Most of the awareness rate of schistosomiasis control knowledge and the rate of correct behavior formation were over 80% in residents and students. Conclusions The achievements of schistosomiasis control are consolidated in Songjiang District; however, there are still risk factors of schistosomiasis transmission, including residual snails, snail diffusion and importation of external source of infection. The future surveillance of schistosomiasis should focus on snails and sources of infection.
