Background: Health behavior was conducive to control the COVID-19 epidemic. This study aimed to determine the differences in health behaviors and related factors among rural-urban residents in China. Methods: From February 14 to 22, 2020, the peak of COVID-19 epidemic in China, a total of 2449 participants(urban residents,1783(72.81%) and rural residents, 666 (27.19%)) were recruited by snowball sampling on WeChat and Tencent QQ social platforms. Data were collected through the Web-questionnaire guided by an information–motivation–behavioral skills model. Multiple-group structural equation model was applied to analyze the factors. Results: Rural residents had lower health behavior scores than urban residents, even after adjusting demographic characteristics (33.86 vs. 34.29, P=0.042, total score was 40). In urban and rural residents, motivation, behavioral skills and health risk stress had significant direct positive and negative influences effects on health behaviors, respectively. Information and positive perception of interventions had direct effects on health behaviors in rural residents, but not in urban residents. All the factors were mediated by behavioral skills in rural and urban residents. Conclusions: This study suggest that the government should pay attention to substantial rural-urban disparities and implement different COVID-19 prevention and intervention policies for health behaviors targeting rural and urban residents.

Background and Aim The risk and prognosis of aspiration pneumonia (AP) after endoscopic submucosal dissection (ESD) are inconsistent among studies. We aim to estimate the incidence, risk factors, and outcome of AP in patients after gastric ESD. Methods PubMed, EMBASE, Cochrane Library, and Web of Knowledge were searched for relevant articles from inception until April 2020. Data involving the incidence, risk factors, and outcomes were extracted. Pooled incidence, odds ratios (ORs), or standardized mean difference (SMD) and 95% confidence intervals (CIs) were calculated. Results Forty records involving 48 674 subjects were finally included. The pooled incidence of AP after gastric ESD was 1.9% (95% CI, 1.2–2.7) via the double arcsine transformation method and 1.6% (1.1–2.5%) via the logit transformation method. Risk factors analyses revealed that old age (OR, 2.52; 95% CI, 1.99–3.18), comorbid pulmonary disease (2.49; 1.66–3.74), comorbid cerebrovascular disease (2.68; 1.05–6.85), remnant stomach (4.91; 1.83–13.14), sedation with propofol (2.51; 1.48–4.28), and long procedural duration (count data: 5.20, 1.25–21.7; measurement data: 1.01, 1.01–1.02) were related to the occurrence of AP. Patients with AP had a longer hospital stay (SMD, 0.56; 95% CI, 0.25–0.87) than those without AP. Conclusions About 1.9% (1.2–2.7%) of the patients who receive gastric ESD may develop AP, resulting in prolonged hospital stay. More attention should be paid in patients who are older; have comorbidities such as pulmonary diseases, cerebrovascular diseases, or gastric remnant; or require a long procedural duration or deep sedation with propofol.

The 1-piece hydrophobic acrylic foldable PC IOL was not suitable for sulcus transscleral fixation because of a high incidence of PDS and pigmentary glaucoma after surgery in a Chinese population.
