BackgroundSleep duration holds considerable importance as an indicator of mental/physical health. The objective of this study was to investigate the association between sleep duration, mental health, and chronic disease prevalence in Koreans.MethodsOf 31,596 subjects eligible for the Korean National Health and Nutrition Examination Survey V (2010–2012), 17,638 participants who answered items on sleep duration (aged ≥19 yrs) were analyzed in a cross-sectional study. Association between sleep duration, mental health, and chronic disease prevalence was assessed using logistic regression, and adjusted for various socioeconomic and lifestyle characteristics.ResultsShort or long sleep duration showed correlations with mental health, and items of significance showed gender-specific patterns. Women displayed significant associations with stress and depressive symptoms, and men with stress, thoughts of suicide, and psychiatric counseling. While stress was related with short sleep duration in both genders, depressive symptoms showed a relationship with long duration in men, and short duration in women. Prevalence of any chronic disease was associated with ≤6 h sleep when adjusted for factors including mental health, and among chronic diseases, cancer and osteoarthritis showed associations with short sleep duration, while diabetes and dyslipidemia were associated with normal sleep duration.ConclusionsMental health problems were associated with sleep duration with gender-specific patterns. Associations with osteoarthritis, cancer, diabetes, dyslipidemia and abnormal sleep duration persisted after adjustment for mental health.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-015-2542-3) contains supplementary material, which is available to authorized users.

This randomized sham-controlled trial suggests that acupuncture treatment shows better effect on the reduction of the bothersomeness and pain intensity than sham control in participants with cLBP.

Current evidence on the effectiveness and safety of Chuna manipulative therapy (CMT) for managing non-acute lower back pain (LBP) is insufficient. We investigated the comparative effectiveness and safety of CMT, a Korean style of manipulation, plus usual care (UC) compared to UC alone for non-acute LBP. We conducted a parallel, two-armed, multi-centered, assessor blinded, pragmatic, randomized controlled trial at four major Korean medical hospitals. Overall, 194 patients were randomly allocated to either CMT plus UC (n = 97) or UC alone (n = 97), for six weeks of treatment and six months follow-up. The primary outcome was measured using the numerical rating scale (NRS) of LBP intensity at 7 weeks. Secondary outcomes included NRS of leg pain, Oswestry Disability Index (ODI) for functional disability, patient global impression of change (PGIC) scale, and safety. A total of 194 patients were included in the intention-to-treat analysis, and 174 patients provided complete data for the primary outcome. At 7 weeks, clinically significant differences between groups were observed in the NRS of LBP (CMT + UC: −3.02 ± 1.72, UC: −1.36 ± 1.75, p < 0.001), ODI scores (CMT + UC: −5.65 ± 4.29, UC: −3.72 ± 4.63, p = 0.003), NRS of leg pain (CMT + UC: −2.00 ± 2.33, UC: −0.44 ± 1.86, p < 0.0001), and PGIC (CMT + UC: −0.28 ± 0.85, UC: 0.01 ± 0.66, p = 0.0119). Mild to moderate safety concerns were reported in 21 subjects. CMT plus UC showed higher effectiveness compared to UC alone in patients with non-acute LBP in reducing LBP and leg pain and in improving function with good safety results using a powered sample size and including mid-term follow-up.

IntroductionDoin therapy is a manual therapy used in Korean rehabilitation medicine. Recently, the use of acupuncture with Doin has increased in clinics and clinical trials have demonstrated its effects. However, well-designed studies examining the efficacy and cost-effectiveness of acupuncture with Doin therapy are rare.Methods and analysisThis multicentre, assessor-blinded, randomised controlled trial with two parallel groups aims to evaluate the clinical effects and cost-effectiveness of acupuncture with Doin therapy. A total of 124 patients (with a neck pain duration of 6 months or longer and a Numeric Rating Scale ≥5) will be recruited at five Korean medicine hospitals. Patients will be randomly allocated to acupuncture with Doin therapy (n=62) and acupuncture alone (n=62) for 5 weeks of treatment. This study will be carried out with outcome assessor and statistician blinding. The primary outcome measure will consist of improvement in neck pain using the Visual Analogue Scale at 6 weeks. The secondary outcomes including measures of pain, functional disability, health-related quality of life and economic evaluation will be conducted at 6 weeks, and 3, 6, 9 and 12 months after treatmentEthics and disseminationThe project is approved by the Institutional Review Board (IRB) of the Jaseng Hospital of Korean Medicine and the Kyung Hee University Korean Medicine Hospital at Gangdong. Dissemination will occur after the findings from this study are published in other peer reviewed journals.Trial registration numbersNCT03558178; KCT0003068; Pre-results.

This is the first cost-effectiveness analysis of Chuna manual therapy (CMT) plus usual Korean traditional medicine for traffic accident victims using a randomized controlled trial. A total of 132 participants were equally allocated to the intervention group receiving 6–11 sessions of CMT plus usual Korean traditional medicine care for three weeks or usual care including acupuncture, cupping, herbal medicine, moxibustion, and traditional physiotherapy at three hospitals. At 12 weeks, from a healthcare perspective, the intervention group had significantly higher costs (mean (SD), $778 (435) vs. $618 (318); difference, $160; 95% CI, $15 to $289; p = 0.005). From a societal perspective, total costs were insignificantly lower in the intervention group (mean (SD), $1077 (1081) vs. $1146 (1485); difference, $−69; 95% CI, $−568 to $377; p = 0.761). The intervention group dominated, with significantly higher QALYs gained at lower overall cost with a 72% chance of being cost-effective. From a societal perspective, the intervention was cost-saving for individuals who had neck pain after car accidents, although it was not cost-effective from the healthcare perspective ($40,038 per QALY gained). Findings support use of CMT as an integrated care treatment for whiplash from a societal perspective. Further studies with larger sample sizes are needed to determine cost-effectiveness in other cultural contexts.
