Comparison of health literacy level among residents with different socio-economic status in Wenling City / 预防医学

Objective To learn the current status of health literacy of residents in Wenling City, and to explore the relationship between health literacy and socioeconomic status. Methods A total of 3200 residents aged 15-69 years old from 6 townships were selected by stratified multi-stage random sampling method and probability proportionate to size sampling (PPS) method, and a questionnaire surveyed was conducted. Results Totally 3189 questionnaires were effective and the overall level of health literacy of residents was 19.79％ (631/3189) . The percentages of residents who had the basic health knowledge and concept, healthy lifestyle and behavior, health related skills were 23.27％、 24.21％ and 23.83％, respectively. About 55.47％ of residents had the literacy of safety and first-aid, which was the highest, followed by 38.66％ with scientific health belief, 32.77％ with literacy for disease prevention, 26.12％ with health information, 14.14％ with primary medical care and 7.49％ with the literacy for chronic disease prevention. Logistic regression model showed that the health literacy level with institutions class was 2.25 times of manual workers class, and the health literacy level of people have bachelor degree or above was 6.93 times less literate or illiterate, and the health literacy level of family income of 200 thousand Yuan and above was 7.70 times of 0～50 thousand Yuan. The health literacy were different among different socioeconomic status residents (P<0.01) . Conclusion There are obvious gaps in health literacy among different socioeconomic status groups. Health education should be strengthened among residents, especially among the manual workers class, low education class and low income class.

Efficacy of continuous stellate ganglion block for prevention of cerebral vasospasm following interventional treatment of intracranial aneurysms / 中华麻醉学杂志

Objective To evaluate the efficacy of continuous stellate ganglion block (SGB) for prevention of cerebral vasospasm (CVS) following interventional treatment of intracranial aneurysms.Methods Forty patients of both sexes with ruptured intracranial aneurysm,aged 20-60 yr,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,with Hunt-Hess grade Ⅰ-Ⅲ,scheduled for elective interventional treatment of intracranial aneurysms,were divided into 2 groups (n =20 each) using a random number table:control group (C group) and continuous SGB group (SGB group).After induction of anesthesia,patients received ipsilateral continuous SGB with 0.25％ ropivacaine 6-8 ml followed by continuous infusion of 0.2％ ropivacaine 2 ml/h for 3 days in group SGB.Transcranial Doppler ultrasound was used to measure the blood flow in bilateral middle cerebral arteries and internal carotid arteries within 3 days after operation,and the development of CVS was assessed.Before operation and at 2 and 6 h and 1 and 3 days after operation,blood samples were collected from the internal jugular vein for determination of plasma melatonin (MT) and endothelin-1 (ET-1) concentrations by enzyme-linked immunosorbent assay.Results Compared with group C,the incidence of CVS (5％) was significantly decreased,and the plasma ET-1 concentration was decreased at 2 and 6 h and 1 and 3 days after operation (P ＜ 0.05),and no significant change was found in plasma MT concentrations at each time point in group SGB (P＞0.05).Conclusion Continuous SGB can effectively prevent the development of CVS following interventional treatment of intracranial aneurysms,and the mechanism may be related to inhibited release of ET-1 from vascular endothelial cells,but not related to MT.

Perceived stress in general public during prevalence of severe acute respiratory syndrome and its impact on health behavior / 中华预防医学杂志

<p><b>OBJECTIVE</b>To find out the perceived stress in general public during prevalence of severe acute respiratory syndrome (SARS) and its impact on health behavior.</p><p><b>METHODS</b>A retrospective survey was conducted in Guangzhou, Hangzhou, and Taiyuan according to the epidemic situations of SARS, and 2532 subjects were randomly selected from constructive industry, school, and commercial business and residents in urban and rural areas. The perceive stress was measured by Chinese perceived stress scale (CPSS), and health related behavior during SARS was tested by uniform and self-made questionnaire. EpiData 2.0 was used for data management and CPSS value was calculated according to answer to 14 questions contained in the scale. Health risk stress among different population group and health related behavior among low, medium and high stress state were analyzed by SPSS 11.5.</p><p><b>RESULTS</b>2424 subjects were involved in the survey. The CPSS value was measured from 0 - 49 (22.7 +/- 6.8), M = 24.0. 39.3% (953/2379) subjects were under the health risk stress. The health related behaviors such as washing hands, opening the window for air, keeping away from others when cough and sneeze, doing exercises etc were reduced with the stress increased. Logistic regression indicated that compared with the persons with the thoughts of nothing serious of SARS, without any dread of SARS, and knowing nothing about prevention of SARS, the perceived stress was significantly related with perceiving of the thread to certain extent (beta = 0.41, Wald chi(2) = 4.84, P = 0.03), worrying little about the epidemic (beta = 0.50, Wald chi(2) = 6.69, P = 0.01), worrying about it to certain extent (beta = 1.39, Wald chi(2) = 48.59, P = 0.00) and scared so much (beta = 1.77, Wald chi(2) = 53.59, P = 0.00), and knowing little about the prevention (beta = 0.74, Wald chi(2) = 4.48, P = 0.03), knowing something about prevention (beta = -0.98, Wald chi(2) = 8.29, P = 0.00) and knowing the prevention very well (beta = -1.18, Wald chi(2) = 10.66, P = 0.00).</p><p><b>CONCLUSION</b>The adoption of health related behaviors declined with increase of perceived stress. Opening connection to authority and government, enhancing the awareness of outburst affairs among general public and providing positive social support may be effective ways to reduce the population perceived stress.</p>

The change of health related behavior during and after severe acute respiratory syndrome prevalence / 中华预防医学杂志

<p><b>OBJECTIVE</b>To describe the changes of health related behavior and influencing factor during and after the prevalence of severe acute respiratory syndrome (SARS), as to providing evidence for inducing public health related behavior to cope with the emergent infectious public health hazards.</p><p><b>METHODS</b>According to the epidemic strength of SARS, Guangzhou, Taiyuan, Hangzhou were selected to be the research areas, and convenience sampling was used to identify 200 city residents, 200 country residents and 400 occupational populations from each area. The uniform and self-made questionnaire was carried out by about 2400 residents.</p><p><b>RESULTS</b>All 2424 subjects completed the questionnaire. The correlation coefficient of scores of health related behavior during and after SARS was 0.782 (P < 0.01). And 39.3% subjects were considered as under the health risked stress by CPSS. Multiple linear regression indicated that the scores of health related behavior were significantly related to the perceived stress, demographic characteristics and recognition of SARS.</p><p><b>CONCLUSIONS</b>The public health related behavior should be developing in the SARS, and part of health related behavior had been kept after SARS and part been decreased. Behavior change should depends on the prevalence of the disease, cultural heritage and behavior variability. More attention should be paid to induce the public psychology and behavior and enhance the degree of recognition on related knowledge through health education as to relieving the stress in populations when we conduct to cope with the emergent public health hazards.</p>
