RESUMEN
PURPOSE: The efficacy of exercise in men with prostate cancer (PCa) on active surveillance (AS) remains unclear. In this meta-analysis, we aimed to examine the effects of exercise in PCa patients on AS. METHODS: A literature search was conducted in PubMed, EMBASE, and the Cochrane Library using search terms, including exercise, PCa, AS, and randomized controlled trials (RCTs). The means and standard deviations for peak oxygen consumption (VO2peak), prostate-specific antigen (PSA) levels, and quality of life (QoL) were extracted for the intervention and control groups. A random-effects model was used to summarize the effects of exercise. RESULTS: Of the 158 identified studies, six RCTs with 332 patients were included. The interventions included lifestyle modifications (aerobic exercise + diet) in three studies and different exercise modalities in three studies. The intervention duration was 2-12 months; three interventions were supervised and three were self-directed. The pooled weighted mean difference between exercise and usual care for VO2peak was 1.42 mL/kg/min (95% confidence interval [CI]: 0.30 to 2.54, P ≤ 0.001). A non-significant effect was observed for QoL (pooled standardized mean difference [SMD]: 0.24, 95% CI: - 0.03 to 0.51, P = 0.08) which became statistically significant and stronger after excluding one outlier study (P < 0.001). Exercise also had a positive effect on PSA levels (pooled SMD: - 0.43, 95% CI: - 0.87 to 0.01, P = 0.05). CONCLUSION: Exercise improves cardiorespiratory fitness and may improve QoL and PSA levels in men with PCa on AS. Further studies with larger sample sizes are warranted to obtain more reliable results.

PURPOSE: The purpose of this qualitative study was to use semi-structured interviews and thematic analysis to elicit key influencing factors (i.e., behavioral, normative, and control beliefs) related to physical activity and exercise in colorectal cancer survivors. METHODS: Colorectal cancer survivors (N = 17) were recruited from exercise programs designed for colorectal cancer survivors at the Yonsei Cancer Center, Seoul, South Korea. A purposive sampling method was used. Interview questions were informed by the theory of planned behavior (TPB). Semi-structured face-to-face interviews were conducted, and open-ended questions addressed the research question. Interviews were transcribed verbatim and analyzed using thematic analysis. RESULTS: Participants were on average 2.2 years post-treatment. The mean age of the sample was 55.9 years. Key behavioral, normative, and control beliefs emerged in the data. For behavioral beliefs, colorectal cancer survivors believed that exercise would result in physical and psychological improvements, and improve their bowel problems. For normative beliefs, most colorectal cancer survivors wanted their oncologists' approval for participation of exercise. Family members, more specifically the spouse, were also influencing factors for colorectal cancer survivors adopting physical activity. The most frequently mentioned control belief was that supervised exercise with an exercise specialist made exercise participation easier. CONCLUSIONS AND IMPLICATIONS: Beliefs identified in this study can inform TPB-based physical activity interventions tailored for colorectal cancer survivors. While information alone may not lead to behavior change, integrating these beliefs with other influential factors can potentially enhance intervention efficacy and promote physical activity in this population.

BACKGROUND: Chronic kidney disease (CKD) poses a significant health challenge, yet early detection remains difficult. Resting heart rate (RHR) has been shown to be a reliable indicator of type 2 diabetes, prompting interest in its potential as an independent predictor of CKD. This study aimed to investigate the association between RHR and CKD prevalence, as well as explore potential interactions between RHR and other risk factors for CKD in a sample of 25,246 adults. METHODS: Data from the Korean National Health and Nutrition Examination Survey (2011-2014) were utilized for this study, with 19,210 participants included after screening. Logistic regression analysis was employed to examine the relationship between RHR and CKD prevalence. Stratified analyses were conducted based on known risk factors for CKD. RESULTS: Participants with an RHR ≥ 90 bpm exhibited a 2.07-fold [95% confidence interval (CI): 1.28-3.34] and 2.22-fold (95% CI: 1.42-3.48) higher prevalence of CKD in men and women, respectively, compared to those with an RHR < 60 bpm. The association between RHR and CKD prevalence was particularly pronounced in younger participants (40-59 years vs. ≥ 60 years), individuals with diabetes (yes vs. no), and those with a longer duration of diabetes (≥ 7 years vs. < 7 years). CONCLUSION: Elevated RHR was found to be significantly associated with a higher prevalence of CKD in both men and women, independent of demographic, lifestyle, and medical factors. These findings suggest that RHR could serve as a valuable predictor for undiagnosed CKD.

OBJECTIVES: To investigate the safety and preliminary efficacy of the combined treatment of focused ultrasound (FUS) and chemotherapy (nab-paclitaxel plus gemcitabine, nPac/Gem) for patients with unresectable pancreatic cancer. METHODS: Patients pathologically diagnosed with unresectable pancreatic cancer were included. Low (Isppa = 1.5 kW/cm2), intermediate (2.0 kW/cm2), and high (2.5 kW/cm2) FUS intensity treatment groups were predefined. A 1% duty cycle and the 3+3 scheme were used. Six combined treatments were performed, and adverse events were assessed. Changes in tumor size and tumor response, CA 19-9 level, and patient-reported outcomes at the immediate follow-up (F/U) and/or at the 3-month F/U and survival were evaluated. RESULTS: Three participants were enrolled in each intensity group. No adverse device effect or dose-limiting toxicity occurred in any of the participants. Seven of the nine participants experienced a >15% tumor size decrease at the immediate F/U CT and at the 3-month F/U CT. The CA 19-9 level decreased in all of the participants at the immediate F/U. All participants in the intermediate-intensity treatment group showed a > 30% tumor size decrease, partial response, and a significant decrease in the CA 19-9 level at 3-month F/U and longer survival (p < 0.05). CONCLUSION: FUS with an intensity of 1.5 to 2.5 kW/cm2 was safe in the combined treatment of FUS and nPac/Gem. Considering the results of the change in tumor size, the change in CA 19-9 level, tumor response, and survival, these FUS parameters can be used for subsequent clinical trials. KEY POINTS: ⢠No adverse device effect or dose-limiting toxicity occurred in any of the participants when focused ultrasound with an intensity of 1.5-2.5 kW/cm2 and a low duty cycle of 1% was combined with chemotherapy. ⢠The intermediate-intensity group showed a >30% tumor size decrease, partial response, and a significant decrease in CA 19-9 in all of the participants at the 3-month follow-up and the longest survival. ⢠Any focused ultrasound setting used in this study could be safe and optimal for subsequent clinical trials.

BACKGROUND AND AIM: Although resting heart rate (RHR) is associated with prevalence and incidence of diabetes, whether it is associated with undiagnosed diabetes is still unclear. We aimed to investigate whether the RHR is associated with the prevalence of undiagnosed diabetes in a large Korean national dataset. METHODS AND RESULTS: The Korean National Health and Nutrition Examination Survey data from 2008 to 2018 were used. After screening, 51,637 participants were included in this study. The odds ratios and 95% confidence intervals (CIs) for undiagnosed diabetes were calculated using multivariable-adjusted logistic regression analyses. Analyses showed that participants with a RHR of ≥90 bpm showed a 4.00- (95% CI: 2.77-5.77) and 3.21-times (95% CI: 2.01-5.14) higher prevalence of undiagnosed diabetes for men and women, respectively, than those with a RHR of <60 bpm. The linear dose-response analyses showed that each 10-bpm increment in RHR was associated with a 1.39- (95% CI: 1.32-1.48) and 1.28-times (95% CI: 1.19-1.37) higher prevalence of undiagnosed diabetes for men and women, respectively. In the stratified analyses, the positive association between RHR and the prevalence of undiagnosed diabetes was tended to be stronger among those who were younger (age: <40 years) and lean (BMI: <23 kg/m2). CONCLUSIONS: Elevated RHR was significantly associated with a higher prevalence of undiagnosed diabetes in Korean men and women, independent of demographic, lifestyle, and medical factors. Accordingly, the value of RHR as a clinical indicator and health marker, especially in reducing the prevalence of undiagnosed diabetes, is suggestible.

OBJECTIVES: To investigate the efficacy and safety of a new portable ultrasound-guided high-intensity focused ultrasound system (USgHIFU) with advanced targeting and beam steering technology for the treatment of uterine fibroids. METHODS: Fifty-nine uterine fibroids from 36 participants (mean age, 44.9 ± 4.1 years) were included from November 2013 to November 2015. All participants were treated with HIFU, with 3D electronic steering. MR imaging studies were performed before HIFU, immediately after HIFU, and 1 month and 3 (or 5) months after the HIFU treatment. The non-perfused volume ratio (NPVR), fibroid volume shrinkage (FVS), symptom improvement, quantified life quality assessment, and safety were analyzed. A long-term follow-up was conducted in July to December 2017 (mean, 32.2 months). RESULTS: The volume of the treated uterine fibroids ranged from 7.5 to 274.4 cm3 (mean, 69.8 cm3; SD, 64.3 cm3). The mean NPVR on the immediate post-HIFU MR imaging was 74.8 ± 25.2%. The mean FVS was 17.3% at 1 month, 33.3% at 3 months, and 45.1% at 5 months after HIFU treatment. The mean treatment time was 44.6 ± 28.2 min per fibroid and 72.9 ± 31.4 min per participant. Uterine fibroid-related symptoms and quality of life showed statistically significant improvement after the HIFU treatment. No significant symptoms related to safety or complications occurred. In the long-term follow-up, 78.8% of those surveyed were satisfied with their HIFU treatment. CONCLUSION: This clinical trial showed that a portable USgHIFU with advanced functions may safely and effectively treat uterine fibroids. KEY POINTS: ⢠A portable compact ultrasound-guided high-intensity focused ultrasound (HIFU) can effectively and safely treat uterine fibroids. ⢠Advanced functions, such as portability, targeted forecasting, electronic beam steering, and interleaved scanning, might be helpful in enhancing the clinical applicability of ultrasound-guided high-intensity focused ultrasound. ⢠In the long-term follow-up of more than 2 years, approximately 80% of those surveyed were satisfied with their HIFU treatment.

π-Conjugated polymers have become qualified candidates for biosensing owing to their unique optoelectronic properties and excellent biocompatibility. In this contribution, nucleotide mismatches in DNA hybridization, being variable in position, are reflected in a stark manner by poly(3-methylthiophene) (P3MT) nanowires (NWs), in which probe DNA sequence is properly functionalized. Selected as the systematic investigation are complementary target DNA (tDNA), random sequence DNA, and three kinds of 1-mer mismatched tDNAs with different mismatch loci away from the NW's surface. Nanoscale optical observation of the single P3MT NWs in solid states reveals that the more distant the mismatch position is from the surface, the higher the photoluminescence (PL) occurs, while the complementary sequence yields the highest but the random one remains the lowest. Hence, the PL intensity increases with the relative length of the DNA-DNA hybridization from the surface. These results deliver a new basis that π-conjugated polymers can be potentially applicable to detailed nucleotide analyses as in single nucleotide polymorphism.

The purpose of our study was to validate a newly developed breath acetone (BrAce) analyzer, and to explore if BrAce could predict aerobic exercise-related substrate use. Six healthy men ran on a treadmill at 70% of maximal oxygen consumption (VO2max) for 1 h after two days of a low-carbohydrate diet. BrAce and blood ketone (acetoacetate (ACAC), beta-hydroxybutyrate (BOHB)) levels were measured at baseline and at different time points of post-exercise. BrAce values were validated against blood ketones and respiratory exchange ratio (RER). Our results showed that BrAce was moderately correlated with BOHB (r = 0.68, p < 0.01), ACAC (r = 0.37, p < 0.01) and blood ketone (r = 0.60, p < 0.01), suggesting that BrAce reflect blood ketone levels, which increase when fat is oxidized. Furthermore, BrAce also negatively correlated with RER (r = 0.67, p < 0.01). In our multiple regression analyses, we found that when BMI and VO2max were added to the prediction model in addition to BrAce, R2 values increased up to 0.972 at rest and 0.917 at 1 h after exercise. In conclusion, BrAce level measurements of our BrAce analyzer reflect blood ketone levels and the device could potentially predict fat oxidation.

BACKGROUND Primary intraventricular hemorrhage (PIVH) is an uncommon type of intracerebral hemorrhage. Owing to its rarity, the clinical and radiological factors affecting outcomes in patients with PIVH have not been widely studied. MATERIAL AND METHODS We retrospectively reviewed 112 patients (mean age 53 years) treated for PIVH at our institution from January 2004 to December 2014. Clinical and radiological parameters were analyzed 3 months after initial presentation to identify factors associated with clinical outcomes, as assessed by the Glasgow Outcome Scale (favorable ≥4, unfavorable <4). RESULTS Of the 99 patients who underwent angiography, causative vascular abnormalities were found in 46%, and included Moyamoya disease, arteriovenous malformation, and cerebral aneurysm. At 3 months after initial presentation, 64% and 36% of patients were in the favorable and unfavorable outcome groups, respectively. The mortality rate was 19%. However, most survivors had no or mild deficits. Age, initial Glasgow Coma Scale (GCS) score, simplified acute physiology score (SAPS II), modified Graeb score, and various radiological parameters reflecting ventricular dilatation were significantly different between the groups. Specifically, a GCS score of less than 13 (p=0.015), a SAPS II score of less than 33 (p=0.039), and a dilated fourth ventricle (p=0.043) were demonstrated to be independent predictors of an unfavorable clinical outcome. CONCLUSIONS In this study we reveal independent predictors of poor outcome in primary intraventricular hemorrhage patients, and show that nearly half of the patients in our study had predisposing vascular abnormalities. Routine angiography is recommended in the evaluation of PIVH to identify potentially treatable etiologies, which may enhance long-term prognosis.

Glioblastoma is the most aggressive primary brain tumor with hypoxia-associated morphologic features including pseudopalisading necrosis and endothelial hyperplasia. It has been known that hypoxia can activate signal transducer and activator of transcription 3 (Stat3) and subsequently induce angiogenesis. However, the molecular mechanism underlying hypoxia-induced Stat3 activation has not been defined. In this study, we explored the possible implication of reactive oxygen species (ROS) in hypoxia-driven Stat3 activation in human glioblastoma. We found that hypoxic stress increased ROS production as well as Stat3 activation and that ROS inhibitors (diphenyleneiodonium, rotenone and myxothiazol) and an antioxidant (N-acetyl-L-cysteine) blocked Stat3 activation under hypoxic conditions. To determine a major route of ROS production, we tested whether nicotinamide adenine dinucleotide phosphate oxidase 4 (Nox4) is involved in hypoxia-induced ROS production. Nox4 expression was found to be increased at both mRNA and protein levels in hypoxic glioblastoma cells. In addition, siRNA-mediated knockdown of Nox4 expression abolished hypoxia induced Stat3 activation and vascular endothelial growth factor expression, which is associated with tumor cells' ability to trigger tube formation of endothelial cells in vitro. Our findings indicate that elevated ROS production plays a crucial role for Stat3 activation and angiogenesis in hypoxic glioblastoma cells.

Astrocyte elevated gene-1 (AEG-1) has recently been proposed to be involved in tumor development, invasion, and metastasis in several human cancers. However, the functional importance of AEG-1 expression in human meningioma has not been determined. We investigate the level of AEG-1 expression by quantitative reverse transcription PCR, immunohistochemistry analysis, and western blotting in various human meningioma tissues and cells. To determine the suppressive effect of AEG-1 on meningioma progression, we inhibited AEG-1 expression using small interfering RNA and examined cell proliferation, apoptosis, colony formation and tumorigenicity in a mouse xenograft model. AEG-1 expression was frequently elevated at both mRNA and protein levels in meningioma tumor tissues and in meningioma-derived cells as well. This elevation was more commonly observed in high-grade tumors than in benign ones. The knockdown of AEG-1 led to a decrease in overall cell proliferation, as well as anchorage-independent growth of malignant meningioma. In addition, apoptotic cell death occurred in AEG-1 depleted meningioma cells through p-Akt and Bcl-2 suppression. Furthermore, a mouse xenograft meningioma model showed that inhibition of AEG-1 expression significantly decreased tumor growth. Altogether, these data show that the elevation of AEG-1 contributes to the malignant progression of meningiomas, suggesting that AEG-1 could be a novel therapeutic target against human meningiomas.

Romo1 is a mitochondrial protein whose elevated expression is commonly observed in various types of human cancers. However, the expression status of Romo1 and its implication in the pathogenesis of human glioblastoma (GBM) remain largely undefined. To understand the role of Romo1 in the progression of GBM, we explored its expression in a series of GBM tissues and cell lines and determined its effect on ROS production, cell proliferation, and tumor growth. Romo1 was frequently overexpressed at the mRNA level in both primary tumors and cell lines and its elevation was more commonly observed in high grade tumors versus low grade tumors. Romo1 expression was associated with ROS production and its knockdown led to a marked reduction of in vitro cellular growth and anchorage-independent growth of GBM. Consistently, Romo1 depletion induced a G2/M arrest of the cell cycle that was accompanied with accumulation of phospho-cdc2. Furthermore, a mouse xenograft assay revealed that Romo1 depletion significantly decreased tumor formation and growth. Therefore, our data demonstrate that Romo1 upregulation is a common event in human GBMs and contributes to the malignant tumor progression, suggesting that Romo1 could be a new therapeutic target for human GBM.

BACKGROUND: Intracerebral hemorrhage (ICH) is a well-known condition, but ICH restricted to the thalamus is less widely studied. We investigated the prognostic factors of thalamic ICHs. MATERIAL AND METHODS: Seventy patients from January 2009 to November 2014 were retrospectively reviewed. Patients who demonstrated spontaneous ICH primarily affecting the thalamus on initial brain computed tomography (CT) were enrolled. Patients were categorized into 2 groups based on their Glasgow Outcome Scale (GOS) scores. Various presumptive prognostic factors were analyzed to investigate relationships between various clinical characteristics and outcomes. RESULTS: Of the enrolled patients, 39 showed a GOS of 4-5, and were categorized as the good outcome group, while another 31 patients showed a GOS of 1-3 and were categorized as the poor outcome group. Initial GCS score, calculated volume of hematoma, presence of intraventricular hemorrhage (IVH), coexisting complications, hydrocephalus, performance of external ventricular drainage, and modified Graeb's scores of patients with IVH were significantly different between the 2 groups. In multivariate analysis, among the factors above, initial GCS score (P=0.002, Odds ratio [OR]=1.761, Confidence interval [CI]=1.223-2.536) and the existence of systemic complications (P=0.015, OR=0.059, CI=0.006-0.573) were independently associated with clinical outcomes. Calculated hematoma volume showed a borderline relationship with outcomes (P=0.079, OR=0.920, CI=0.839-1.010). CONCLUSIONS: Initial GCS score and the existence of systemic complications were strong predictive factors for prognosis of thalamic ICH. Calculated hematoma volume also had predictive value for clinical outcomes.

BACKGROUND AND PURPOSE: There is a scarcity of information on the epidemiology and natural course of moyamoya disease. The aim of this study was to investigate the nationwide epidemiological features of moyamoya disease in Korea, including incidence, prevalence, and survival. METHODS: We used the data from nationwide, population-based Health Insurance Review and Assessment Service claims database and Rare Intractable Disease registration program, which includes physician-certified diagnoses based on uniform criteria for moyamoya disease from 2007 to 2011. Age-specific incidence and prevalence were calculated, and survival was examined using Kaplan-Meier method. RESULTS: The total number of patients with moyamoya disease was 8154 in 2011, with a female-to-male ratio of 1.8. The incidence from 2007 to 2011 was 1.7 to 2.3/10(5), and the prevalence in 2011 was 16.1/10(5). In total, 66.3% of patients aged 0 to 14 years underwent surgery, whereas only 21.5% in the older than 15 years age group underwent surgery. The 1- and 5-year survival rates of adult patients were 96.9% and 92.9%, respectively, and of child patients were 99.6% and 99.3%, respectively. CONCLUSIONS: The prevalence and incidence presented in this study are higher than those in previous studies. This study demonstrates that the burden of moyamoya disease in Korea is substantial.

PURPOSE: Microsurgical bilateral decompression via a unilateral approach for lumbar spinal stenosis is a less invasive technique compared to conventional laminectomy. Although many technical reports have demonstrated acceptable overall surgical outcomes for this approach, no studies have attempted to clarify the clinical outcomes thereof in regard to anatomical variance of the spinal canal. This study was conducted to analyze the clinical outcomes of microsurgical bilateral decompression via a unilateral approach according to spinal canal morphology in degenerative lumbar spinal stenosis. METHODS: Between January 2008 and December 2009, 144 patients with single-level spinal lumbar stenosis underwent microsurgical bilateral decompression via a unilateral approach by a single surgeon. Patients were categorized into three groups according to spinal canal shape: round (n = 42), oval (n = 36), and trefoil (n = 66), and clinical parameters were assessed both before and after surgery with 2-3 years of follow-up. RESULTS: Mean visual analog scale (VAS) and Oswestry disability index (ODI) decreased after surgery, respectively, from 8.1 and 59.8 % to 2.1 and 19.1 % in the round shaped spinal canal group, from 7.2 and 47.1 % to 2.2 and 15.1 % in the oval shaped spinal canal group, and from 6.8 and 53.6 % to 3.6 and 33.3 % in the trefoil shaped spinal canal group. In all groups, VAS and ODI scores significantly improved postoperatively (p < 0.01), although less improved VAS and ODI scores were observed in the trefoil shaped spinal canal group (p < 0.01). The overall patient satisfaction rate was 66.7 %; however, statistically significant lower satisfaction rates were reported in the trefoil shaped spinal canal group (p < 0.01). CONCLUSIONS: Microsurgical bilateral decompression via a unilateral approach may be a good modality for treating round or oval shape spinal canal stenosis, but is not recommended for trefoil-shaped-stenosis. The current authors recommend performing the bilateral decompression technique in cases of trefoil-shaped-spinal canal stenosis.

BACKGROUND: Although the majority of patients with minimal acute subdural hematomas (aSDHs) can be managed conservatively, some require delayed aSDH evacuation due to hematoma enlargement. This study was designed to determine the risk factors associated with delayed hematoma enlargement leading to surgery in patients with aSDHs who did not initially require surgical intervention. METHODS: From 2002 to 2012, 98 patients were treated for nonoperative aSDHs following mild head injury (Glasgow Coma Scale scores of 13-15). The outcome variables were radiographic evidence of SDH enlargement on serially obtained computed tomography (CT) images and later surgical evacuation. Univariate and multivariate analyses were applied to both the demographic and initial radiographic features to identify risk factors for SDH progression and surgery. RESULTS: Overall, 64 patients (65 %) revealed minimal SDH or spontaneous hematoma resolution (conservative group) with conservative management at their last follow-up CT scan. The remaining 34 patients (35 %) received delayed hematoma evacuation (delayed surgery group) a median of 17 days after the head trauma. There were no significant differences between the two groups for baseline characteristics, including age, injury type, degree of brain atrophy, prior history of antithrombotic drugs, and coagulopathy. The presence of cerebral contusions and subarachnoid hemorrhages was more common in the conservative group (p = 0.003 and p = 0.003, respectively). On multivariate analysis, hematoma volume (p = 0.01, odds ratio [OR] = 1.094, 95 % confidence interval [CI] = 1.021-1.173) and degree of midline shift (p = 0.01, OR = 1.433, 95 % CI = 1.088-1.888) on the initial CT scan were independently associated with delayed hematoma evacuation. CONCLUSIONS: A critical proportion of patients with minimal aSDHs occurring after mild head injury can progress over several weeks and require hematoma evacuation. Especially patients with a large initial SDH volume and accompanying midline shift require careful monitoring of hematoma progression.

Primary extraosseous intracranial Ewing sarcoma (ES) is an extremely rare disease, limited to the pediatric population, that primarily originates in the skull. Here, we present an unusual case of adult Ewing's sarcoma originating from the brain parenchyma. The 50-year-old male patient visited our hospital with severe headache lasting 3 weeks. MRI presented 6.1×6.2×5.2 cm sized heterogeneously enhanced mass containing peritumoral edema in the right frontal lobe. The patient underwent right frontal craniotomy, at which time the gray and red masses adhered to the surrounding brain parenchyma. The mass was completely resected using neuronavigation and electrophysiological monitoring. Histopathological examination revealed ES-compatible findings of small round cell tumor and CD-99 positive membranous immunostaining. Next generation sequencing revealed translocation and fusion of EWSR1 and FLI1, consistent with a confirmed diagnosis of ES. Consequently, the patient underwent postoperative radiotherapy. The present case revealed adult primary intracranial ES arising from the frontal lobe. Although its etiology remains poorly understood, intraparenchymal ES should be included in the differential diagnosis of parenchymal brain tumors.
RESUMEN
BACKGROUND: Various physical activity (PA) guidelines recommend leisure PA and resistance exercise (RE). However, the impact of PA and RE on the prevalence of depressive symptoms remains unclear. We investigated whether meeting PA and RE guidelines is associated with the prevalence of depressive symptoms using nationally representative samples. METHODS: We analyzed data from 11,829 (5111 male and 6718 female) participants aged 19+ years in the Korean National Health and Nutrition Examination Survey (2016 and 2018). Those with doctor's diagnosis of depression or with a cut-off score of ≥11 on the Patient Health Questionnaire-9 were defined as having depressive symptoms. PA and RE were measured using a validated Global PA Questionnaire. Logistic regression analysis was used to examine the association between participating in leisure PA, simultaneously meeting RE guidelines, and experiencing depressive symptoms. RESULTS: Those who participated in leisure PA and met RE guidelines had a lower prevalence of depressive symptoms than those who did not (p for trend <0.001). After adjusting for covariates, those who participated in leisure PA and met RE guideline were significantly less likely to have depressive symptoms in male (OR = 0.52, 95 % CI 0.32-0.84) and female (OR = 0.71, 95 % CI 0.48-1.06), compared with those who did not participate in leisure PA but also did not meet RE guideline. LIMITATIONS: The cross-sectional nature of the data prevented causal claims. CONCLUSIONS: Participation in leisure PA and RE was associated with a lower prevalence of depressive symptoms. This suggests both leisure PA and RE should be encouraged as effective means for preventing depression.
