Evidence on the effect of aerobic walking (AW) and exercise intensity on cognitive function in patients with schizophrenia is lacking. In total, 79 patients with schizophrenia were recruited for a 12-week randomized control trial and allocated to the treatment-as-usual (TAU, n = 38) and treatment-as-usual plus AW (TAW, n = 39) groups. The TAW participants joined a supervised 12-week AW program consisting of 30-min sessions five times per week while wearing a Fitbit Charge 2 device. Cognitive function was evaluated using the Brief Assessment of Cognition in Schizophrenia. After randomization, 67 (34 TAU and 33 TAW) participants joined the 12-week trial and were included in the intention-to-treat analysis. Multivariate general linear model repeated measures analysis revealed no significant time × group interaction effect on cognitive function changes between the TAU and TAW groups and a marginally significant group effect on verbal fluency (p = 0.09). The interaction effect of time and treatment group on verbal fluency (p = 0.05) was marginally significant between the high and low AW intensity groups, whereas a significant group effect on attention and processing speed (p = 0.04) was observed. Supervised 12-week AW of moderate intensity may have potential cognitive benefits for patients with schizophrenia.

This study recruited patients with schizophrenia. Factors associated with the level of sleep disturbance and CPD were identified using univariate linear regression, and further selected into a stepwise multivariate linear regression model. Using structural equation modeling, a mediation model was developed to test the mediating effect of CPD on the association between social impact and sleep disturbance. After estimating with the stepwise and bootstrap regression, higher levels of CPD were associated with higher levels of social anxiety and subjects without a regular diet. Sleep disturbance was associated with a higher level of social anxiety, a history of psychological trauma, chronic disease, and...

This study determined the willingness of men who have sex with men to self-pay for PrEP and factors associated with the likelihood of condom use if taking PrEP. The Taiwan 2014 MSM Online Sex Survey was conducted and data such as demographics, attitudes toward PrEP, and sexual behaviors in the previous 3 months were collected. Of the 1,151 MSM who participated, 56% were willing to take PrEP, but only 23% were willing to self-pay $340 for PrEP. Willingness to self-pay for PrEP was significantly associated with the previous receipt of nonoccupational post-exposure prophylaxis (adjusted odds ratio [AOR], 3.02, 95%CI [1.49, 6.12]), and positive attitudes toward PrEP (AOR, 3.02, 95%CI [2.19, 4.17]). Of MSM who are willing to use PrEP, 73.6% would maintain condom use if taking PrEP. If PrEP is made available in Taiwan, more efforts should be focused on increasing awareness of MSM who are practicing risky behaviors.

The Methadone Maintenance Treatment Outcome Study was an 18-month prospective study from March 2007 to July 2008. Data collection was conducted in the substance use disorders treatment outpatient clinics of three hospitals in southern Taiwan. A total of 368 opioid-dependent heroin users (13.6% women) were interviewed at baseline and at 3-, 6-, 9-, 12-, 15- and 18-month follow-ups. The level of self-efficacy in reducing risky injection behaviors was repeatedly assessed using the Self-Efficacy Scale for HIV Risk Behaviors. Demographic and substance use characteristics, HIV serostatus, family function, depression, and pros and cons of heroin use were collected at baseline, and methadone dosage at each follow-up interview and the duration of retention in the MMT program were also recorded. The results of the generalized estimating equation indicated that a lower educational level, concurrent methamphetamine use, a younger age at first heroin use, a lower methadone dosage, a higher level of depression, and a shorter duration of retention in the MMT program were predictive of a lower level of self-efficacy in reducing risky injection behaviors. This study found that personal and MMT-related factors were predictive of a lower level of self-efficacy among heroin users receiving MMT. Programs implemented to promote a higher level of self-efficacy should be provided to heroin users in the MMT program.
