Objective: This study explored whether the efficacy of food safety education interventions can be increased by message framing among medical university students, and demonstrated the role of personal involvement within the message recipient in moderating framed effects. Methods: A cross-sectional study of food safety message framing was conducted among medical university students (randomly selected 1353 participants). An online self-administered questionnaire was used to collect information. Wilcoxon rank-sum test and Ordered multivariate logistic regression were utilised in the data analyses. Results: The present study showed significant differences in acceptance between the gain- and loss-framed groups (p < 0.001). Participants with higher personal involvement had higher acceptance than those with low personal involvement in gain- and loss-framed message models (p < 0.001). The acceptance of participants who were concerned about their health condition was higher than those who were neutral regarding their health condition (p < 0.001) and participants who suffered a food safety incident had higher acceptance than those who did not (p < 0.05). Conclusions: This study portrayed the selection preference of message framing on food safety education among medical university students in southwest China. Participants exposed to loss-framed messages had higher message acceptance than those exposed to gain-framed messages. Personal involvement may affect the food safety message framing. Public health advocates and professionals can use framed messages as a strategy to enhance intervention efficacy in the process of food safety education.

Background: Smoking is among the most preventable causes of death globally. Tobacco cessation can lessen the number of potential deaths. The China Tobacco Cessation Guidelines encourage medical staff to perform the 5As (Ask, Advise, Assess, Assist, Arrange) when delivering tobacco dependence treatments to patients. Nursing students will develop to be nurses in the future and they have to finish 9 months of clinical practicum study in the last year at hospitals or care centers. However, the frequency of behaviors used to help smokers quit among Chinese nursing internship students is unclear. This study analyzed the rate of nurse interns’ performance of the 5As and which demographic characteristics, perceptions of smoking and knowledge predicted higher performance of the 5As. Methods: The cluster sampling method was used to select 13 teaching hospitals among 29. All nursing intern students were expected to finish the questionnaire about their 5As behaviors to help patients quit smoking. Their 5As performances were scored from one to five with 5 being the best and scores were summed. A multivariate linear mixed-effect model was employed to test the differences between their 5As. Results: Participating in the survey were 1358 interns (62.4% response rate). The average scores were as follows—Ask—3.15, Advise—2.75, Assess—2.67, Assist—2.58 and Arrange—2.42. A total of 56.3% students perceived that medical staff should perform the 5As routinely to help patients quit smoking. On the other hand, 52.1% viewed clinical preceptors as role models of the 5As. School education regarding tobacco control, smoking dependence treatment, self-efficacy and positive intentions were predictors of higher performance of the 5As (p < 0.001). Conclusions: Nursing internship students seldom administered tobacco dependence treatments to patients. It is essential to improve the corresponding education, skills and self-efficacy of the 5As. Meanwhile, clinical preceptors should procure more training in the responsibilities and skills related to tobacco cessation. In this way, clinical preceptors can be role models of the 5As and impart positive influences on interns.

BackgroundAcute gastrointestinal illness (AGI) imposes considerable social and economic burden on low and middle-income countries. This study aimed to estimate the occurrence, distribution, and burden of self-reported AGI in Gansu Province of northwest China, where economic growth rates have lagged far behind those of other regions in China and systematic studies to investigate the burden of AGI are still lacking.MethodsTwelve-month, retrospective face-to-face surveys were conducted in three sentinel sites between June 2012 and May 2013. Respondents were asked if they had experienced diarrhoea or vomiting in the 28 days prior to the interview.ResultsIn total, 2094 interviews were completed. The adjusted monthly prevalence was 8.5% with an incidence rate of 1.16 episodes of AGI per person-year. Healthcare was sought by 73.8% of those reporting illness. Of the cases who visited a doctor, 50.5% submitted a stool sample. The use of antibiotics was reported by 65.6% of the cases and 53.3% took antidiarrhoeals. In the multivariable model, age, household income and sentinel site were significant risk factors of being a case of AGI.ConclusionsThe burden of AGI was considerable in Gansu Province of northwest China. Ongoing research to identify the main causes of AGI is needed for more accurate estimate of the burden of AGI in this region.Electronic supplementary materialThe online version of this article (doi:10.1186/1471-2458-14-787) contains supplementary material, which is available to authorized users.

Mental health problem among university students is an emerging public health issue, and mental health education has always been the focus of attention for universities. However, limited attention has been paid to the effect of students' acceptance of health messages. Previous studies have found that message framing plays a key role in the process of responding to health-promoting messages. In this backdrop, the study aimed to examine the effects of goal-framed messages on mental health education among medical university students and investigate the moderating role of personal involvement. A cross-sectional study was conducted on medical university students. An online self-administered questionnaire was used to collect data. Wilcoxon rank-sum test and ordinal logistic regression were used for data analysis. Results showed significant differences in message acceptance between the gain-and loss-framed groups (p < 0.001). Participants with high personal involvement had higher message acceptance than those with low personal involvement in gain-and loss-framed message models (p < 0.05). Specifically, participants who related to roommates with high intimacy had higher message acceptance than those who related to roommates generally (p < 0.05). Participants who were concerned about their health condition had higher message acceptance than those who were neutral about their health condition (p < 0.001). Evidence of advantages of gain-over loss-framed messages on mental health among medical university students was found. The hypothesis that personal involvement with a health issue affects the acceptance of message framing was supported. Public health advocates can use framed message as a strategy to improve the efficacy of intervention in mental health education.
