Background/Purpose. Sleep plays an important role in individuals’ health. The functions of the brain, the cardiovascular system, the immune system, and the metabolic system are closely associated with sleep. As a prevalent sleep disorder, insomnia has been closely concerned, and it is necessary to find effective therapies. In recent years, a growing body of studies has shown that mind-body therapies (MBTs) can improve sleep quality and ameliorate insomnia severity. However, a comprehensive and overall systematic review has not been conducted. In order to examine the effect of MBTs on insomnia, we conducted a systematic review and meta-analysis evaluating the effects of MBTs on sleep quality in healthy adults and clinical populations. Methods. PubMed, EMBASE, the Cochrane Library, and review of references were searched up to July 2018. English language studies of all designs evaluating the effect of MBTs on sleep outcomes in adults with or without diseases were examined. To calculate the SMDs and 95% CIs, we used a fixed effect model when heterogeneity was negligible and a random effect model when heterogeneity was significant. Results. 49 studies covering 4506 participants published between 2004 and 2018 were identified. Interventions included meditation, tai chi, qigong, and yoga which lasted 4 to 24 weeks. The MBTs resulted in statistically significant improvement in sleep quality and reduction on insomnia severity but no significant effects on sleep quantity indices, which were measured by sleep diary or objective measures. We analyzed the effects of tai chi and qigong separately as two different MBTs for the first time and found that qigong had a slight advantage over tai chi in the improvement of sleep quality. Subgroup analyses revealed that the effect of MBTs on sleep quality in healthy individuals was larger than clinical populations. The effect of MBTs might be influenced by the intervention duration but not the frequency. Conclusions. MBTs can be effective in treating insomnia and improving sleep quality for healthy individuals and clinical patients. More high-quality and well-controlled RCTs are needed to make a better conclusion in further study.

About one-third of participants (32.5%) indicated that they were very concerned about some aspect of their appearance unrelated to weight, with six female participants (1.3%) screening positive for body dysmorphic disorder (BDD). Those who displayed concern with their appearance (including those who did not screen positive for BDD) had higher levels of depressive and social anxiety symptoms than those who had no appearance concerns.

Post-stroke depression (PSD) is a very common complication that leads to increased physical disability, poor functional outcome, and higher mortality. Therefore, early detection and treatment are very important. Since there are currently no specific guidelines for this disorder in China, the purpose of this study was to develop PSD guidelines and provide suggestions for clinicians and related workers.

Objective: To investigate the state of middle school students' obesity in Xiangtan, China and to study the influence of Internet addiction on obesity. Subjects: 1,150 junior and senior middle school students in Xiangtan, China. Design and Methods: The research subjects were select randomly for the study. The height and body weight of human body were measured and the obesity state was judged according to BMI value and the Working Group on Obesity in China (WGOC) standard. The questionnaire for the survey of middle school students' basic situation was designed and a survey of the respondents' personal information and the contributory factors to obesity was conducted. The Middle School Students' Internet Addiction Diagnosis Scale was adopted for measuring and judging the Internet addiction of the research subjects. Results: (1) The total detection rate of obesity was 23.57%. (2) The overall detection rate of Internet addiction was 21.23%. (3) The detection rate of obesity in middle school students with Internet addiction (32.92%) was significantly higher than that without Internet addiction (21.06%). Logistic regression showed that Internet addiction was an independent risk factor of obesity. Conclusion: Internet addiction is related to obesity of middle school students.

The purpose of this study was to evaluate the impact of progressive muscle relaxation on state anxiety and self-efficacy in hospitalized patients admitted for an extremity fracture receiving elective surgery. Eighty four patients met the inclusion criteria and all were randomly assigned to either the progressive muscle relaxation group or the control group. The control group received standard orthopedic nursing care, and the experimental group received standard care along with daily progressive muscle relaxation throughout their hospitalization. The State Anxiety Inventory and Self-Efficacy Scales were administered before and after the intervention. Both paired-sample t tests and independent t tests showed that progressive muscle relaxation is effective in reducing state anxiety and enhancing the self-efficacy of patients with extremity fracture undergoing an elective surgery.
