Objective In order to carry out proper education and intervention of AIDS based on different features and demands of different majors, this study aimed to compare the difference of college students from six majors in China in the aspects of AIDS-related knowledge, attitudes and behaviors. Methods A questionnaire survey was carried out among 18,644 students in 30 colleges/universities from 9 provinces of China, who were recruited through stratified cluster sampling. AIDS-related knowledge, attitude, condom-use intention, self-efficacy and sexual behavior of these students were investigated. Results AIDS-related knowledge level of students majoring in education was the lowest while that of medical students was the highest as well as highest self-efficacy of condom use. Students of music or fine arts had the strongest intention to use condoms, while the students majoring in education had the weakest. The sexually active percentages of male students from different majors ranked as follows: music or fine arts (29.5%), minority nationality (12.2%), science & tech (10.9%), medicine (10.6%), education-major (10.0%), and liberal arts (8.2%). Among female students, the rank was music or fine arts (11.0%), science & tech (6.2%), education-major school (4.5%), minority nationality (4.5%), liberal arts (4.1%), and medicine (2.8%). Conclusion It is urgent to enhance proper AIDS-related education and intervention based on the features and demands of students from different majors or universities, for example, to enhance comprehensive AIDS prevention education among students major in education and to increase behavioral skills to prevent sexually transmitted diseases among students from colleges or faculty of music or fine arts.

This study aimed to predict stage of exercise among Chinese patients with type 2 diabetes by using an extended theory of planned behavior model (TPB) incorporating descriptive norm and self-identity. Patients and Methods: Participants (N=791) were included in a cross-sectional study. Structural equation modeling was used to explain how the extended TPB could predict the stage of exercise. Results: The model accounted for 41% of the variance in stage of exercise and 81.1% of the variance in intention. Intention (β=0.359, P<0.01) and self-identity (β=0.236, P<0.001) had a direct effect on stage of exercise. Self-identity (β=0.261, P<0.001), descriptive norm (β=0.035, P<0.05) and PBC (β=0.683, P<0.001) were strong predicators of intention. The effects of self-identity and PBC on behavior were significantly mediated via intention. Age, BMI and stage of diet behavior were found to be significantly related to intention and behavior. Conclusion: This study has tested the usefulness of the extended TPB for explaining exercise in Chinese diabetic patients. To promote patients to start or continue exercising, interventions should target self-identity and controllability for physical activity.

BACKGROUND In China, for most diabetic patients, wearable activity trackers are an innovative product that has not yet been generally accepted and used. Many studies have proved personality traits to affect patients' self-management behavior with chronic diseases, the willingness to adopt medical services, and willingness to use mobile healthcare equipment. OBJECTIVE This study aimed to investigate the influence of personality traits of type 2 diabetes patients on the use intention of the intelligent wearable device -- wearable activity trackers METHODS A self-designed questionnaire and Chinese Big Five Personality Inventory brief version (CBF-PI-B) were used to investigate type 2 diabetes mellitus (T2DM) patients from 22 community health service stations affiliated to 4 community health service centers in Tongzhou District and Shunyi District of Beijing. RESULTS A total of 728 cases were included in this study. Monofactor analysis indicated differences between patients with different genders in neuroticism, individual innovation, and behavioral intention, differences between patients with different ages in neuroticism, openness, individual innovation, and privacy concerns, differences between patients with different degree of education in openness, extraversion, perceived ease of use, the individual innovation and social image, and differences between patients with different income levels in openness, extraversion, perceived ease of use and individual innovation. The structural equation showed that perceived ease of use, perceived usefulness, social image, and privacy concern had direct effects on behavioral intention (β=0.158, 0.223, 0.151, -0.657). Neuroticism had a positive impact on social image and privacy concerns (β=0.144, 0.154). Conscientiousness and openness had a positive influence on perceived ease of use (β=0.147, 0.142). Agreeableness showed negative impacts on both perceived ease of use and privacy concerns (β=-0.108, -0.251). Openness and extroversion both had a positive impact on individual innovation (β=0.149, 0.180) while openness generated a positive influence on social image (β=0.189). CONCLUSIONS Different personality traits had influences on individual innovation, privacy concerns and social image, and indirectly affect patients’ intention to use wearable activity trackers. Therefore, personalized guidance and health education could be carried out according to different personality traits when using intelligent wearable devices in the intervention of patients with type 2 diabetes.
