Post-traumatic stress disorder (PTSD) severely disrupts the daily lives of veterans and active duty personnel and may influence their suicidal behaviour. This study provides insight into existing research on PTSD in veterans through a narrative review. Exercise was found to reduce PTSD symptoms in veterans at both psychological and physiological levels, which in turn inhibits their suicidal tendencies. At the psychological level, exercise improved veterans' Subjective Well-Being and Psychological Well-Being, and at the physiological level, it improved veterans' brain structure, neuroendocrine system, and immune system. By combing these mechanisms in detail, we hope to provide theoretical support for the implementation of exercise interventions in the treatment of veterans with PTSD. However, it is important to note that the specifics of the exercise program, such as the optimal type, dosage, and duration to alleviate PTSD symptoms, remain unclear and require further research and exploration.

Objective: The main objectives of our study are evaluating the health literacy level among women with gestational diabetes mellitus (GDM) in Southwest China and explore the influencing factors, using a multidimensional health literacy assessment scale (Chinese version of the HLS-14). Given that the HLS-14 has not been used in GDM previously, its reliability and validity testing was included as a secondary objective.

Method: It was a cross-sectional survey with 565 GDM pregnancies. The Maternal and child health information access questionnaire, Chinese version of the HLS-14, Perceived Social Support Scale (PSSS) and General Self-efficacy Scale (GSES) was used to collect health information access behaviors, health literacy, social support and self-efficacy levels, respectively. SPSS 21.0 was used for descriptive statistical, multiple stepwise linear regression analysis and exploratory factor analysis (EFA). Amos 26.0 was used for confirmatory factor analysis (CFA).

Results: The Chinese version of HLS-14 has good reliability and validity in GDM pregnancies. The Cronbach's α are 0.849, 0.866, 0.859, and 0.883, respectively. The exploratory factor analysis extracted three common factors with a cumulative variance contribution rate of 68.405%. The confirmatory factor analysis model fit was good (χ²/df = 2.595, RMSEA = 0.055, IFI = 0.970, TLI = 0.963, CFI = 0.970). The HL level in pregnancies with GDM was moderate with a mean score of 3.26 ± 0.41, of which 24.10% had limited HL, 41.87% had moderate HL, and 34.03% had adequate HL. Regression analysis showed that the women with higher family support (β = 0.298, p < 0.001), recording pregnancy management diary (β = 0.199, p < 0.001), higher the family income (β = 0.140, p < 0.001), lower pre-pregnancy BMI (β = -0.116, p = 0.004), longer time spent searching for health information (β = 0.111, p = 0.006), and searching for health information through a medical health information website (β = 0.093, p = 0.019) had higher HL levels. These variables explained 23.1% of the variance in HL.

Conclusion: The Chinese version of the HLS-14 has good applicability in the GDM pregnancies. The HL level of them is moderate, needs to be improved. Healthcare professionals should focus on the GDM population with low family income and high pre-pregnancy BMI, fully mobilize their social support system, provide reliable access to information, encourage all GDM pregnancies to use pregnancy management diaries to record their self-management behaviors, and ensure the effectiveness of health education.

Background: Khat chewing has become a global phenomenon, resulting in significant physical and mental health issues as well as socioeconomic crises. However, evidence is scarce on Ethiopian youths' behavioral intentions toward khat chewing, particularly in the Raya-Azebo district of the southern zone of the Tigray region. As a result, this study aimed to assess the intention to chew among youths in Raya-Azebo district, Southern Tigray, Ethiopia.

Methods: A community-based cross-sectional survey was conducted among 627 youths in northern Ethiopia's Raya-Azebo district. Data were collected using a structured, interviewer-administered questionnaire. A multivariable linear regression model was used to predict the contribution of independent variables and identify variables strongly associated with chewing among youths.

Results: A considerable proportion, 192 (30.62%) of youths, had the intention to chew khat in the next 6 months. The component of the theory of planned behavior independently explained the variance in intention to chew by 83%. The strongest predictors of intention to chew were attitude (β = 0.35, p < 0.001), subjective norm (β = 0.297, p < 0.001), and perceived behavioral control (β = 0.15, p = 0.01).

Conclusion: Behavioral intention toward khat chewing was a function of attitude, subjective norm, and perceived behavioral control toward khat chewing. Strategies to empower youths to change a positive attitude toward khat chewing, programs targeted at resisting social pressures, and increasing self-efficacy to combat chewing are needed.

Objective: This study evaluated the effectiveness of tai chi, enhanced by communication technologies, in improving cognitive and physical functioning in patients with mild cognitive impairment, and to compare these effects with traditional tai chi.

Methods: A systematic search across four academic databases identified 16 studies with 1,877 participants. Data were expressed as weighted or standardized mean differences with 95% confidence intervals.

Results: A meta-analysis revealed significant improvements in Mini-Mental State Examination scores and Timed Up and Go results in patients with mild cognitive impairment following tai chi intervention. Subgroup analysis indicated that both communication technology-based tai chi and traditional tai chi produced varying improvements in cognitive and physical function.

Conclusion: This study confirms the importance of tai chi for cognitive and physical functioning in patients with mild cognitive impairment. Compared with traditional tai chi, communication technology-based tai chi showed greater benefits in promoting rehabilitation. The effective and feasible interventions could improve the physical health of many older adult patients, these findings provide valuable insights and decision-making guidance for clinical practice and public health with older patients with mild cognitive impairment.

Objectives: Besides physical health risks, large public health events also exert negative impacts on people's mental health. We aimed to explore the prevalence and correlates of mental distress and its association with psychological resilience among countries amid the Omicron wave.

Methods: We conducted cross-sectional surveys simultaneously in China and South Korea from March 15 to 30, 2023. Brief Resilience Scale (BRS), Generalized Anxiety Disorder 7-item (GAD-7) scale, and Patient Health Questionnaire-9 (PHQ-9) scale were used to measured psychological resilience and mental distress.

Results: Self-reported rates of anxiety and depressive symptoms in 3,000 Chinese participants were 24.5% and 30.5%, while the above-mentioned rates were 17.2%and 34.4% in 1,000 Korean participants. Chinese participants had a marginally higher BRS score. Psychological resilience was inversely associated with the prevalence of anxiety symptoms and depressive symptoms. Similar results can be observed in Korea. Results remained robust in all models.

Conclusion: Chinese and Korean populations reported a high prevalence of mental distress with variations in different characteristics, indicating practical implications for developing tailored mental health policies and services in the context of large public health events.

Background: Placental abruption is a critical obstetric condition characterized by the premature separation of the placenta from the uterus, leading to severe maternal and fetal complications. In Ethiopia, the maternal and perinatal morbidity and mortality rates are alarmingly high, and placental abruption significantly contributes to these adverse outcomes. Despite its severity, there is a lack of comprehensive data on the burden, risk factors, and outcomes associated with placental abruption in the Ethiopian context. Thus, the study aimed to investigate the adverse perinatal outcomes of placental abruption and the factors associated with these outcomes among pregnant women admitted to the University of Gondar Comprehensive Specialized Hospital in Ethiopia.

Method: An institution-based retrospective cross-sectional study was conducted among 367 pregnant women who were admitted and managed for placental abruption from January 1, 2021, to January 1, 2023, at the University of Gondar Comprehensive Specialized Hospital. A simple random sample method was employed to choose the medical records. Data was collected using a checklist prepared with the KOBO collect tool and then exported to SPSS version 25.0. Variables having a p-value of less than 0.05 were deemed significant in the multivariable logistic regression analysis that was done. The adjusted odds ratio with a 95% confidence interval was reported.

Result: The prevalence of adverse perinatal outcome of placental abruption was 39.2, 95% CI: 34.3-44.1. The most common adverse outcomes were prematurity (25.6%), low birth weight (25.6%), and NICU admission (13.9%). Severe placental abruption [AOR (CI) = 8.82 (4.48-17.31)] and abruption at preterm gestation [AOR (CI) = 18.71 (9.59-36.42)] were significant predictors of adverse perinatal outcomes.

Conclusion: The adverse perinatal outcomes of pregnancies complicated by placental abruption in this study were higher compared to other studies in Ethiopia. The degree of placental abruption and gestational age at diagnosis were significant associates of adverse perinatal outcomes. The study highlights the critical need for patient-centered counseling on antenatal bleeding to encourage early healthcare-seeking behavior, close follow up for those undergoing expectant management and the early detection and management of placental abruption to improve perinatal outcomes.

Purpose: Sarcopenia, an age-related complication, constitutes a major public health problem given the aging of the population. However, it is frequently overlooked and undertreated in mainstream practice. The study aimed to investigate the correlations between triglyceride-glucose (TyG) index and TyG-body mass index (BMI) and sarcopenia in non-diabetic middle-aged and older women and whether they would be helpful indicators of sarcopenia.

Patients and methods: This cross-sectional study was conducted in the Department of Endocrinology, Hebei Medical University Third Hospital. This study prospectively enrolled 460 non-diabetic postmenopausal women aged ≥50 years.

Results: As TyG and TyG-BMI increased, the prevalence of sarcopenia decreased. In multivariate analysis, the TyG index and TyG-BMI index were inversely associated with sarcopenia (OR: 0.492; 95% CI: 0.256-0.944 and OR: 0.948; 95% CI: 0.934-0.962). Women in the fourth TyG-BMI quartiles showed decreased OR of 0.009 (95% CI: 0.001-0.072) for sarcopenia with respect to first quartiles after adjusting confounding factors. The area under the curve (AUC) for TyG index in the diagnosis of sarcopenia was 0.598 (95% CI: 0.529-0.666), while the AUC for TyG-BMI index was 0.858 (95% CI: 0.816-0.899).

Conclusion: Higher TyG index and TyG-BMI index protected against sarcopenia in non-diabetic middle-aged and older females. Moreover, the TyG-BMI index was a reliable and cost-efficient biomarker to predict sarcopenia.

Background: Self-rated health (SRH) is a single-item subjective indicator that asks individuals to assess their overall health and acts as a good indicator to reveal general health status. This study aimed to determine the SRH status and determining factors.

Methods: This was a population-based cross sectional study conducted in Ilam city (West of Iran) in 2023. A total of 1,370 people were invited to participate in the study using multi-stage stratified cluster random sampling method. Demographic and SRH status data were collected by face-to-face interview. SRH was indicated by a single question in five scales of very good, good, fair, poor and very poor. Multiple ordinal logistic regression was used for data analysis.

Results: The 59.38% (95% CI: 56.76 to 62) participants reported a good SRH status. By ordinal multiple logistic regression, odds ratio (OR) and 95% confidence interval (CI) was calculated and based on that, female gender [OR: 1.68 (1.29 to 2.20)], not having insurance coverage [OR: 1.35; (1.01 to 1.80)], history of job loss [OR: 1.72; (1.28 to 2.31)], hopelessness for the future [OR: 5.07; (3.96 to 6.49)], and having underlying diseases [OR: 2.95; (2.25 to 3.88)], were positively associated with poor SRH status. The Kurd race [OR: 0.45; (0.25 to 0.78)], higher economic status [OR: 0.72; (0.54 to 0.96)] and use of health care service [OR: 0.68; (0.53 to 0.88)] were negatively associated with poor SRH status. The most effective variables for poor SRH status were hopelessness about the future and suffering from underlying diseases.

Conclusion: It is important to devise corrective measures and effective public health policies to address causes and factors associated with poor SRH. It is also necessary for local health officials to allocate financial resources and introduce other kinds of supportive initiatives to provide targeted support for those who are struggling with poverty and suffering chronic diseases.
