Knowledge of common cancers among new-entry health science students in Japan and Vietnam.

BACKGROUND: The incidence and mortality rates of cancer are rapidly increasing worldwide. This study aimed to assess the knowledge of common cancers among new-entry health science students in Japan and Vietnam, thereby providing insights for implementing appropriate medical educational interventions. METHODS: This cross-sectional study was conducted among new-entry health science students at Hiroshima University, Japan, and the University of Medicine and Pharmacy at Ho Chi Minh City, Vietnam. A printed predesigned questionnaire consisting of eleven questions was distributed to the participants during the freshmen health screening at the beginning of the academic year to assess their knowledge of cancer. RESULTS: A total of 2,748 new-entry health science students participated in the study, including 394 (14.3%) Japanese students and 2,354 (85.7%) Vietnamese students. Most cancer knowledge levels in Japanese students were significantly higher than those in Vietnamese students (p < 0.001), except for human papillomavirus (HPV) infection awareness. For this understanding, only 14.8% of Japanese students selected the correct answer, which was significantly lower than the 22.4% of Vietnamese students (p = 0.001). Both the Japanese and Vietnamese students had limited knowledge regarding the connection between HPV infection and cancer and the link between estrogen-progestogen menopausal therapy and breast cancer. Additionally, female students had better knowledge about breast, skin, and endometrial cancers than male students. CONCLUSIONS: Japanese students generally exhibited higher levels of cancer knowledge than Vietnamese students, except for HPV infection recognition. Both groups had limited knowledge regarding the connection between HPV infection and cancer and the relationship between estrogen-progestogen menopausal therapy and breast cancer.

Association of mental health conditions and functional gastrointestinal disorders among Vietnamese new-entry medical students.

BACKGROUND: Functional gastrointestinal disorders (FGIDs), also known as disorders of gut-brain interaction, occur not only in the elderly but also in young adults. This study aimed to evaluate the association between mental health conditions and FGIDs among Vietnamese new-entry medical students. METHODS: This cross-sectional study was conducted in February 2022 among new-entry medical students in Ho Chi Minh City, Vietnam. A printed questionnaire was distributed to all students on the day of freshmen health screening. Their urine samples were collected to screen for Helicobacter pylori infection using rapid urinary test. FGIDs were diagnosed using ROME IV criteria. Gastroesophageal reflux disease (GERD) was defined as the presence of typical reflux symptoms at least twice a week. Mental health conditions, including generalized anxiety disorder (GAD) and major depressive disorder (MDD), were identified using Generalized Anxiety Disorder Assessment-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) scales, respectively. RESULTS: Among 400 new-entry medical students who participated in the study, the overall prevalence of FGIDs was 10.3% (functional dyspepsia 6.5%, irritable bowel disease 5.5%). The overlap syndrome (OS) of GERD-FGIDs or different FGIDs was present in 3.0% of participants. The prevalences of GAD and MDD were 6.8% and 10.2%, respectively. The urinary test was positive in 180 (45.0%) participants. In the multivariable logistic regression analysis, MDD was significantly associated with not only the risk of FGIDs (OR = 5.599, 95%CI: 2.173-14.430, p<0.001) but also the risk of OS (OR = 10.076, 95CI%: 2.243-45.266, p = 0.003). CONCLUSIONS: MDD is associated with FGIDs and OS among new-entry medical students.
