Source of Information on Intentions to Adopt Protective Behaviours During COVID-19 in China.

Introduction: COVID-19 spread across China and other countries in a matter of weeks. Yet, it is uncertain how people have responded to protective behaviours in this pandemic. This study aims to evaluate how trust in different types of information sources influences the intention to adopt protective behaviours. Methods: In total, 122 Chinese completed a survey on Qualtrics in March 2021. Data on demographic information, protective behaviours, trust in formal information, trust in informal information, perceived risk, worry and social desirability were collected. Structural equation modelling (SEM) was used to identify associations between these variables. Results: Trust in formal information was significantly associated with perceived risk (ß = -.18) and significantly and positively associated with worry (ß = .28). Trust in informal information was significantly and positively associated with perceived risk (ß = .57). Subsequently, perceived risk was significantly associated with social distancing (ß = -.17), and worry was significantly and positively associated with mask wearing (ß = .25) and significantly associated with hand washing (ß = -.27). Trust in formal information was significantly and positively associated with hand washing (ß = .26) while trust in informal information was significantly and positively associated with social distancing and hand washing (ß = .26). Perceived risk was significantly and positively associated with worry (ß = .32). Conclusion: People who trust in informal information from social media and interpersonal communication would be more likely to adopt mask wearing and hand washing protective behaviours. People who trust in formal information from government-agency source would have a lower perceived risk of COVID-19 and are less likely to adopt social distancing, but people who trust in formal information have a greater worry about contracting COVID-19 and are more likely to wear masks.

Do medical students know enough about smoking to help their future patients? Assessment of New York City fourth-year medical students' knowledge of tobacco cessation and treatment for nicotine addiction.

PURPOSE: Practicing physicians underutilize U.S. Department of Health and Human Services evidence-based approaches to nicotine addiction and treatment. Few studies have assessed medical student knowledge in this area. This study examined New York City fourth-year medical students' knowledge of tobacco cessation and treatment of nicotine addiction. METHOD: The authors conducted a Web-based survey, comprising 27 closed- and open-ended questions, of six of seven New York City medical schools in the spring of 2004. They drew questions from international, national, and local surveys on tobacco and health, U.S. Department of Health and Human Services tobacco treatment guidelines, and prior studies. Primary outcome measures were knowledge of the epidemiology of smoking, benefits of cessation and treatment of nicotine addiction, clinical cessation practices, and students' use of tobacco and intentions to stop smoking. RESULTS: Of 943 fourth-year medical students, 469 (50%) completed an online survey. Students had good knowledge of the epidemiology of smoking, including its prevalence and health effects, with most responding correctly to relevant questions (mean correct response 79%; SD = 9.4). Students demonstrated a fair understanding of the benefits of cessation (mean correct response, 67%; SD = 19.2) and treatment of nicotine addiction (mean correct response, 61%; SD = 13.2). Three hundred students (64%) rated their own preparation to assist patients to quit as less than adequate. CONCLUSIONS: Fourth-year medical students at the participating schools in New York City understood the harms of smoking but needed more information on the benefits of stopping smoking and treatment of nicotine addiction.

Tobacco use and readiness to quit smoking in low-income HIV-infected persons.

The study aim was to identify covariates of smoking status and readiness to quit that encompassed key sociodemographic and health status variables, health-related quality of life, drug use and unprotected sex, and tobacco use variables in a cohort of low-income persons living with HIV. We also examined the impact of HIV diagnosis on smoking cessation. The sample (N = 428) was mostly male (59%) and Black (53%) or Hispanic (30%), and had a high school education or less (87%). Mean age was 40 years. Two-thirds of participants were current smokers, 19% former smokers, and 16% never smokers. Current smokers smoked a mean of 16 cigarettes/day for 22 years; 42% were in the precontemplation stage of readiness to quit smoking, 40% were contemplators, and 18% were in preparation. Most current smokers (81%) reported receiving medical advice to quit smoking. Multivariate logistic regression analyses indicated that current smokers, compared with former smokers, were more likely to use illicit drugs, perceive a lower health risk for continued smoking, and report less pain. Current smokers, compared with nonsmokers (former and never smokers), were more likely to report greater illicit drug use in their lifetime, current illicit drug use, and less pain. A multiple linear regression indicated that greater current illicit drug use, greater emotional distress, and a lower number of quit attempts were associated with lower stage of readiness to quit smoking. These findings confirm a high prevalence of smoking among HIV-infected persons and suggest a complex interplay among drug use, pain, and emotional distress that impact smoking status and, among smokers, readiness to quit. Tobacco control programs for HIV-infected persons should build motivation to quit smoking and address salient barriers to cessation--such as comorbid drug use, emotional distress, pain, and access to and coverage for treatment--and should educate smokers regarding the HIV-specific health benefits of cessation.
