RESUMEN
Objective@#To understand health literacy and associated factors of freshmen from Jiangsu Province, and to provide reference for youth health education.@*Methods@#From 2017 October to 2018 October, a total of 15 602 college freshman were randomly selected from 20 universities in Jiangsu Province via stratified cluster sampling method. Structural questionnaires were used to investigate the status of health literacy. The χ 2 test and multivariate Logistic regression model were used to analyze the influencing factors of health literacy.@*Results@#The health literacy level of college freshmen from Jiangsu Province was 20.2%, among which the literacy levels of knowledge, behavior and skills were 23.0%, 30.7% and 31.5% respectively. The literacy levels of the six public health issues, including safety and first aid, scientific health attitude, knowledge of prevention and treatment of infectious diseases, health information, basic health care, and prevention and treatment of chronic diseases, from high to low, were 72.8%, 58.7%, 28.5%, 28.2%, 20.3% and 15.9%, respectively. Multivariate Logistic regression analysis has showed that students from undergraduate colleges(OR=2.77, 95%CI=2.47-3.11), urban areas(OR=1.20, 95%CI=1.07-1.34), or southern Jiangsu regions(OR=1.10, 95%CI=1.00-1.22), being the only child(OR=1.13, 95%CI=1.03-1.25), higher maternal education level (OR=1.53, 95%CI=1.30-1.79), having both parents(OR=1.16, 95%CI=1.00-1.34), reported higher level of health literacy.@*Conclusion@#The three aspects and six dimensions of health literacy of college freshmen were unbalanced. Health literacy is a shared function of multiple factors including society, family, and individuals. It is essential to promote health education through more efforts on key issues, in order to effectively elevate the health literacy level of adolescent students.
RESUMEN
Objective To investigate the characteristics of muscle edema and fatty infiltration in thighs and relationship with clinical symptoms in Chinese patients with different phenotypes of dysferlinopathy.Methods A total of 32 patients were enrolled , including 13 limb-girdle muscular dystrophy 2B (LGMD2B), 13 Miyoshi myopathy (MM), 4 proximodistal myopathy and 2 hyper-creatine-kinase-emia.Clinical symptoms were evaluated using modified Gardner-Medwin and Walton ( GM-W) score.Muscle MRI was performed in thighs to observe fatty infiltration and edema.We then compared the age of onset , disease duration, GM-W score, muscle edema and muscle fatty infiltration between LGMD 2B and MM groups,and the relationship of muscle edema score and fatty infiltration score with disease duration and GM-W score in all patients.Results The median GM-W score was 4.00 (2.00,5.00) in all patients, 4.00 (3.00,4.50)in LGMD2B and 4.00(2.00,5.00)in MM, respectively.Muscle fatty infiltration appeared in 30 cases (93.75%), with the same pattern in LGMD2B and MM.The mean fatty infiltration score was 28.20 ±12.86 in all patients, 28.50 ±13.03 in LGMD2B and 29.00 ±12.63 in MM, respectively.Muscle edema appeared in 26 cases (81.25%) with same pattern in LGMB2B and MM.The mean edema score was 18.36 ±13.60 in all patients, 22.88 ±11.59 in LGMD2B and 16.77 ±13.80 in MM.The age of onset , disease duration, GM-W score, muscle fatty infiltration and edema score were not significantly different between LGMD2B and MM patients.Muscle fatty infiltration score significantly correlated with GM-W score (rs=0.737,P=0.000) and disease duration (rs=0.637,P=0.000).Conclusions Fatty infiltration and edema in thigh muscles are very common in patients with dysferlinopathy , with similar radiological changes in main subtypes.The muscle fatty infiltration can be used as a predictor of disease progression.
