Health disparities among the western, central and eastern rural regions of China after a decade of health promotion and disease prevention programming / 华中科技大学学报（医学）（英德文版）

Health disparities between the western, central and eastern regions of rural China, and the impact of national health improvement policies and programming were assessed. A total of 400 counties were randomly sampled. ANOVA and Logistic regression modeling were employed to estimate differences in health outcomes and determinants. Significant differences were found between the western, central and eastern rural regions in community infrastructure and health outcomes. From 2000 to 2010, health indicators in rural China were improved significantly, and the infant mortality rate (IMR), maternal mortality rate (MMR) and under 5 mortality rate (U5MR) had fallen by 62.79%, 71.74% and 61.92%, respectively. Central rural China had the greatest decrease in IMR (65.05%); whereas, western rural China had the greatest reduction in MMR (72.99%) but smallest reduction in U5MR (57.36%). Despite these improvements, Logistic regression analysis showed regional differences in key health outcome indicators (odds ratios): IMR (central: 2.13; western: 5.31), U5MR (central: 2.25; western: 5.69), MMR (central: 1.94; western: 3.31), and prevalence of infectious diseases (central: 1.62; western: 3.58). The community infrastructure and health outcomes of the western and central rural regions of China have been improved markedly during the first decade of the 21st century. However, health disparities still exist across the three regions. National efforts to increase per capita income, community empowerment and mobilization, community infrastructure, capacity of rural health facilities, and health literacy would be effective policy options to attain health equity.

Acceptability of physical examination by male doctors in medical care: Taking breast palpation as an example / 华中科技大学学报（医学）（英德文版）

In this study, we conducted an investigation among medical workers, patients and college students concerning their acceptability of breast palpation performed by male doctors (hereinafter referred to as "acceptability", or "the examination", respectively, if not otherwise indicated), to get the information about their acceptability and reasons for accepting or declining the examination among the three population. A questionnaire investigation was conducted in 500 patients with breast diseases, 700 students of medical colleges, and 280 medical workers working in hospitals. The subjects were asked to choose between two options: accept or do not accept (the examination). The subjects were asked to fill out the questionnaire forms on free and anonymous basis and the questionnaire forms were collected on spot, immediately after completion. The questionnaires collected were coded, sorted out and checked. Data of the eligible questionnaires were input into Epidata software and analyzed by SPSS. Upon the establishment of the database, the intra-group data were tested by utilizing χ(2) test. Among 1480 questionnaires, 1293 (90.41%) questionnaires were retrieved. Our results showed that 56.78% of patients reported that they could accept breast palpation by male doctors. About 59.66% of medical staff expressed their acceptance of the examination, but only 35.03% of students said the examination. On the basis of this study, we were led to conclude that the examination is not well accepted by different populations, and therefore, (1) medical professionals and administrators should pay attention to the gender-related ethics in their practice and the feeling of patients should be respected when medical examinations involve private or sensitive body parts; (2) to this end, related departments should be properly staffed with doctors of both sexes, and this is especially true of the departments involving the examination or treatment of private or sensitive body parts; (3) health education should, among other things, include helping female patients to overcome the fear and anxiety in such examinations. This is of great importance since some women may miss the opportunity to get timely diagnosis.

Influencing factors of mental health of medical students in China / 华中科技大学学报（医学）（英德文版）

This study investigated the mental health status of medical students in China, and analyzed the influencing factors in order to provide evidence for mental health education for medical students. A stratified cluster sampling method was used to recruit medical students from Huazhong University of Science and Technology, China. The questionnaire survey on general information and Symptom Checklist 90 (SCL-90) were used for investigation and analysis. The results showed among the 1137 valid questionnaires, 278 (24.45%) participants had SCL-90 score ≥ 160. The top three mental problems of medical students were obsessive-compulsive disorder, interpersonal sensitivity and depression in terms of the factor score ≥ 2.5 and the number of participants who reflected on the diseases. The third-year medical students had the worst mental health status, and fifth-year medical students had the best mental health status. Students from rural area had more psychological problems than those from urban area; furthermore, students with high professional satisfaction, those who were the single child of the family, non-poor students, and those whose parents had high education level had better mental health status. It was concluded that the mental health of medical students is not optimistic in China. Medical students have some mental health problems of different degrees. Factors that influence the mental health of medical students include academic pressure, professional satisfaction level and family environment.

Factors influencing the utilization of postpartum visits among rural women in China / 华中科技大学学报（医学）（英德文版）

Postpartum visits (PPVs) are still underutilized in rural China, and identification of factors that influence PPV use is important in ensuring the utilization of maternal health services and for wellbeing of women. A cross-section study was undertaken to collect related data from 347 rural women interviewed six weeks or more after delivery, and an ANOVA was performed to find whether there were significant differences in the number of PPVs among different rural areas in China. According to Andersen's socio-behavioral model of health service use, factors were divided into equitable and inequitable ones. Chi-squared test, univariate and multiple analyses were used to determine the equity of PPV use by identifying factors that were most strongly associated with the use of a PPV. The results showed that 20.2% of the respondents (n=70) did not receive any PPVs, and 62.5% (n=173) of those who had PPVs (n=277) did not receive standard PPVs (referring to at least 3 visits). There was no significant difference among different rural areas in terms of the number of PPVs (F=1.514, P=0.211). Multiple regression analyses revealed that enabling factors such as compensation for delivery expense [OR (95% CI)=2.825 (1.331, 5.995)], village type [OR (95% CI)=1.802 (1.021, 3.182)] and service quality [OR (95% CI)=1.847 (1.074, 3.176)] were strongly associated with PPV use. Both enabling factors such as home visits [OR (95% CI)=1.855 (1.085, 3.174)], service quality [OR (95% CI)=1.993 (1.155, 3.439)] and need factors such as low birth weight [OR (95% CI)=4.424 (1.482, 13.203)] were significantly associated with standard PPV use. Our results suggested that the equitable access to PPVs has been considerably improved in rural areas in China. The associations between inequitable factors and PPV use warrant further exploration, and policies aimed at improving quality and patterns of service supply are needed in order to ensure a full equitable access to maternal health services.

Impact evaluation of HIV/AIDS education in rural Henan province of China / 华中科技大学学报（医学）（英德文版）

Nowadays, there is a trend of HIV prevalence transmitting from high-risk group to average-risk group in China. Rural China is the weak link of HIV prevention, and rural areas of Henan province which is one of the most high-risk regions in China have more than 60% of the AIDS patients in the province. Thus, improving the HIV awareness and implementing health education become the top-priority of HIV/AIDS control and prevention. A multistage sampling was designed to draw 1129 people living with HIV/AIDS (PLWHAs) and 1168 non-PLWHAs in 4 prevalence counties of Henan province. A health promoting and social-psychological support model was constructed to improve the health knowledge of participants. Chi-square tests and unconditional logistic regression were performed to determine the intervention effect and influencing factors. All groups had misunderstandings towards the basic medical knowledge and the AIDS transmission mode. Before the intervention, 59.3% of the HIV/AIDS patients and 74.6% of the healthy people had negative attitudes towards the disease. There was statistically significant difference in the improvement of knowledge, attitude and action with regards to HIV prevention before and after intervention (P<0.05). PLWHAs who were males (OR=1.731) and had higher education level (OR=1.910) were found to have better HIV/AIDS health knowledge, whereas older PLWHAs (OR=0.961) were less likely to have better HIV/AIDS health knowledge. However, the intervention effect was associated with the expertise of doctors and supervisors, the content and methods of education, and participants' education level. It was concluded that health education of HIV/AIDS which positively influences the awareness and attitude of HIV prevention is popular in rural areas, therefore, a systematic and long-term program of HIV control and prevention is urgently needed in rural areas.
