Abstract Background: To investigate the prevalence of pterygium and associated factors in Han and Mongolian adults at four survey sites in Inner Mongolia, China.Methods: We conducted a population-based, cross-sectional study as part of the China National Health Survey (CNHS). By means of a stratified sampling method, we finally included 2,651 participants of 30 years of age or older from a total of 3,468 eligible residents. Factors associated with pterygium were analysed by a univariate analysis and logistic regression models.Results: The study population included 1,910 Han and 741 Mongolian adults. The mean age±standard deviation of the study cohort was 48.93±11.06 years. The overall prevalence of pterygium was 6.4% (n=169); 1.4% (n=38) of the cases were bilateral and 4.8% (n=128) were unilateral. The most common grade of pterygium was Grade 2. Based on the results of the univariate analysis, eleven factors were included in a multivariate analysis. The results indicated that age (P<0.001), outdoor occupation (P=0.026), and time spent in rural areas (P<0.001) were significantly associated with pterygium. Sex and ethnicity were not identified as risk factors.Conclusions: Our results indicated that outdoor occupation, old age and more time spent in rural areas were risk factors for pterygium in Inner Mongolia. At the same time, town as a survey site (Hohhot and Tsining District) was a protective factor for pterygium. Ethnicity, gender, smoking, diabetes and high blood pressure are not associated with pterygium.Trial registration KEYWORDS: pterygium, prevalence, Han and Mongolian, risk factors, protective factors

Abstract Background: To investigate the prevalence of and factors associated with pterygium in Han and Mongolian adults at four survey sites in Inner Mongolia, China. Methods: A population-based, cross-sectional study was conducted. Using a stratified sampling method, we eventually included 2,651 participants of at least30 years of age from a total of 3,468 eligible residents. Factors associated with pterygium were analysed using univariate analysis and logistic regression models. Results: There were 1,910 Han adults and 741 Mongolian adults included in this study. The mean± standard deviation of age for individuals in the study cohort was 48.93±11.06 years. The overall prevalence of pterygium was 6.4% (n=169), and the prevalences of bilateral and unilateral pterygium were 1.4% (n=38) and 4.8% (n=128), respectively. The most common grade of pterygium was Grade 2. After univariate analysis, eleven factors were considered in a multivariate analysis. The results indicated that age (P<0.001), education level (P<0.001), outdoor occupation (P=0.026), and time spent in rural areas (P<0.001) were significantly associated with pterygium, whereas gender and ethnicity were not risk factors. In subgroup analysis, BMI≥28 was a protective factor for Han individuals (OR 0.42, 95% CI 0.21-0.81, P=0.01), but a risk factor for Mongolian individuals (OR 2.39, 95% CI 1.02-5.58, P=0.044). The BF% in Han and Mongolian individuals had significant difference (P<0.001). Conclusions: Our results indicated that an outdoor occupation, old age and time spent in rural areas are risk factors for pterygium in Inner Mongolia. Living near an urban survey site (Hohhot and Tsining District) and having a higher education level are protective factors for pterygium. Ethnicity, gender, smoking, diabetes and high blood pressure are not associated with pterygium. Different dietary structures in Han and Mongolian adults may lead to different fat content of body and therefore contributes to the prevalence of pterygium.

AbstractThis cross-sectional study investigated the characteristics of cervical HPV infection in Changsha area and explored the influence of Candida vaginitis on this infection. From 11 August 2017 to 11 September 2018, 12,628 outpatient participants ranged from 19 to 84 years old were enrolled and analyzed. HPV DNA was amplified and tested by HPV GenoArray Test Kit. The vaginal ecology was detected by microscopic and biochemistry examinations. The diagnosis of Candida vaginitis was based on microscopic examination (spores, and/or hypha) and biochemical testing (galactosidase) for vaginal discharge by experts. Statistical analyses were performed using SAS 9.4. Continuous and categorical variables were analyzed by t-tests and by Chi-square tests, respectively. HPV infection risk factors were analyzed using multivariate logistic regression. Of the total number of participants, 1753 were infected with HPV (13.88%). Females aged ≥ 40 to < 50 years constituted the largest population of HPV-infected females (31.26%). The top 5 HPV subtypes affecting this population of 1753 infected females were the following: HPV-52 (28.01%), HPV-58 (14.83%), CP8304 (11.47%), HPV-53 (10.84%), and HPV-39 (9.64%). Age (OR 1.01; 95% CI 1–1.01; P < 0.05) and alcohol consumption (OR 1.30; 95% CI 1.09–1.56; P < 0.01) were found to be risk factors for HPV infection. However, the presence of Candida in the vaginal flora was found to be a protective factor against HPV infection (OR 0.62; 95% CI 0.48–0.8; P < 0.001). Comparing with our previous study of 2016, we conclude that the subtype distribution of HPV infection is relatively constant in Changsha. Our data suggest a negative correlation between vaginal Candida and HPV, however, more radical HPV management is required in this area for perimenopausal women and those who regularly consume alcohol.

Public Health Threat

Injury is a serious public health threat as it is one of the leading cause of death globally. This study aims to assess the prevalence of injury, pattern of injury and its associated factors among people residing in a rural area of Aurabani VDC of Eastern Nepal. A population based cross sectional study was carried out among 552 people residing in selected wards with door to door visit. The prevalence of minor injury was 3.1% and major was 0.4% per year in the study.Most common mode of injury was fall and most common type was incised wound. Injuries mostly occurred in extremities, in morning time, autumn season and in roads while most of the injuries were accidental in nature.
