Introduction: Children are widely recognized as a vulnerable population during disasters and emergencies. The COVID-19 pandemic, like a natural disaster, brought uncertainties and instability to the economic development of the society and social distancing, which might lead to child maltreatment. This study aims to investigate whether job loss, income reduction and parenting affect child maltreatment. Methods: We conducted a cross-sectional online survey of 600 randomly sampled parents aged 18 years or older who had and lived with a child under 10 years old in Hong Kong between 29 May to 16 June 2020. Participants were recruited from a random list of mobile phone numbers of a panel of parents. Of 779 recruited target parents, 600 parents completed the survey successfully via a web-based system after obtaining their online consent for participating in the survey. Results: Income reduction was found significantly associated with severe (OR = 3.29, 95% CI = 1.06, 10.25) and very severe physical assaults (OR = 7.69, 95% CI = 2.24, 26.41) towards children. Job loss or large income reduction were also significantly associated with severe (OR= 3.68, 95% CI = 1.33, 10.19) and very severe physical assaults (OR = 4.05, 95% CI = 1.17, 14.08) towards children. However, income reduction (OR = 0.29, 95% CI = 0.15, 0.53) and job loss (OR = 0.47, 95% CI = 0.28, 0.76) were significantly associated with less psychological aggression. Exposure to intimate partner violence between parents is a very strong and significant factor associated with all types of child maltreatment. Having higher levels of difficulty in discussing COVID-19 with children was significantly associated with more corporal punishment (OR = 1.19, 95% CI = 1.05, 1.34), whereas having higher level of confidence in managing preventive COVID-19 behaviors with children was negatively associated with corporal punishment (OR = 0.87, 95% CI = 0.76, 0.99) and very severe physical assaults (OR = 0.74, 95% CI = 0.58, 0.93). Conclusions: Income instability such as income reduction and job loss amplified the risk of severe and very severe child physical assaults but protected children from psychological aggression. Also, confidence in teaching COVID-19 and managing preventive COVID-19 behaviors with children was significantly negatively associated with corporal punishment during pandemic.
BackgroundIntimate partner violence (IPV) related injuries have been recognized among health care professionals. However, few studies have provided detailed information on injuries to the head, neck and face regions in Chinese women. As abused Chinese women are generally unwilling to disclose IPV and there are differences in socio-demographic characteristics, societal norms and behaviours, the women may exhibit different patterns, aetiology and risk factors of IPV-related HNF injuries. This study aims to examine the patterns of head, neck and face injuries presenting to Accident and Emergency departments, including the anatomical regions, types, severity, aetiology and demographic and non-demographic risk factors of injuries inflicted by intimate partners in Chinese context.MethodsMedical charts of 223 women presented to the Accident and Emergency departments of two regional hospitals in Hong Kong between January 2010 and December 2011 were reviewed independently by two reviewers.ResultsHead, neck and face injuries remained the most common injuries found in abused Chinese women (77.6%), and punching with a fist was the most common aetiology (60.2%). In particular, punching with a fist was significantly associated on the upper third of the maxillofacial region (p = .01) and the back part of the head (p = .03). Moreover, cohabiting and separated women were more likely to have multiple injuries than those who were married (OR = 3.3, 95% CI = 1.4, 7.8; OR = 2.1, 95% CI = .4, 11.9).ConclusionsThe findings enhance the understanding of head, neck and face injuries and inform clinicians about the linkage among injuries and risks in abused Chinese women.
The C-DRS-15 was demonstrated to be a reliable and valid measurement to assess hardiness in Chinese women.
Fluorescence-guided surgery using 5-aminolevulinic acid (5-ALA) is now a widely-used modality for glioblastoma (GBM) treatment. However, intratumoral heterogeneity of fluorescence intensity may reflect different onco-metabolic programs. Here, we investigated the metabolic mechanism underlying the heterogeneity of 5-ALA fluorescence in GBM. Using an in-house developed fluorescence quantification system for tumor tissues, we collected 3 types of GBM tissues on the basis of their fluorescence intensity, which was characterized as strong, weak, and none. Expression profiling by RNA-sequencing revealed 77 genes with a proportional relationship and 509 genes with an inverse relationship between gene expression and fluorescence intensity. Functional analysis and in vitro experiments confirmed glutaminase 2 (GLS2) as a key gene associated with the fluorescence heterogeneity. Subsequent metabolite profiling discovered that insufficient NADPH due to GLS2 underexpression was responsible for the delayed metabolism of 5-ALA and accumulation of protoporphyrin IX (PpIX) in the high fluorescence area. The expression level of GLS2 and related NADPH production capacity is associated with the regional heterogeneity of 5-ALA fluorescence in GBM.
Purpose: A deterioration in bone strength and balance performance after breast cancer treatment can result in injurious falls. Therefore, interventions need to be developed to improve the bone strength and balance ability of breast cancer survivors. This cross-sectional exploratory study aimed to compare the bone mineral density (BMD), balance performance, balance self-efficacy, and number of falls between breast cancer survivors who practiced qigong, breast cancer survivors who did not practice qigong, and healthy individuals. Methods: The study included 40 breast cancer survivors with more than 3 months of qigong experience, 17 breast cancer survivors with no qigong experience, and 36 healthy controls. All the participants underwent dual-energy X-ray absorptiometry scans to measure their lumbar spine, total hip, femoral neck, and total radius BMDs. The participants also underwent a timed one-leg stand test to measure their single-leg standing balance. The participants’ balance self-efficacy was assessed using the activities-specific balance confidence scale, and the number of falls experienced by each participant was assessed in a face-to-face interview. Results: The lumbar spine, total hip, femoral neck, and total radius BMDs were similar between the 3 groups (P > .05). The breast cancer-qigong group outperformed the breast cancer-control group by 27.3% when they performed the one-leg stand test on a foam surface (P = .025), and they also had a higher balance self-efficacy score (P = .006). Nevertheless, the numbers of falls were comparable between the 3 groups (P > .05). Conclusion: Qigong may be a suitable exercise for improving the balance performance and balance self-efficacy of breast cancer survivors.
Intimate partner sexual violence (IPSV) among emerging adults, including heterosexuals and sexual minorities in the Chinese population, is poorly understood. Focusing on college students, the objectives of the present study were to estimate the prevalence of IPSV among Chinese emerging adults, examine the association between sexual orientation and IPSV, and evaluate the mental health and quality of life of survivors of IPSV. Data were collected from four university campuses in Hong Kong. A total of 1,015 participants were included in the data analysis. The prevalence of IPSV as identified by Conflict Tactics Scale (CTS)-2 was 12.1%. There was no gender difference in the prevalence of IPSV. Multiple logistic regression found that being older; having experienced childhood sexual abuse and having a smoking habit; and belonging to a sexual minority were factors associated with IPSV. Multiple linear regression found that IPSV survivors were more likely to have higher levels of anxiety and depression, more severe psychosomatic symptoms, and poorer quality of life in three domains: psychological, social relationships, and environment when compared with those without IPSV experience. The documented factors underscored the importance of awareness that men and sexual minorities might incur IPSV, which should receive more attention in IPSV prevention programs. Also, interventions for IPSV survivors should be targeted at improving their mental health and quality of life and sex education should place more emphasis on sexual consent and sexual health in dating relationships.
Objective: Our study focused on understanding on the ways that abused Chinese women cope and aimed to examine the mediating role of coping strategies between the relationships of intimate partner violence (IPV; including partner stalking) and mental health problems. Method: A population-based household survey was completed by 550 Chinese community-dwelling women. Data on the mediating roles of coping strategies were examined using structural equation models. Results: The prevalence of IPV among Chinese women was 22.9% for psychological abuse, 6.5% for physical abuse, 2.2% for sexual abuse, and 4.2% for partner stalking in the past year. Abused women used more active coping (p = .01), planning (p = .006), and self-distraction (p = .02) than nonabused women. Results supported the mediating effect of problem-focused and passive coping strategies, but not emotion-focused coping, in the pathways of IPV and mental health outcomes (root mean squared error of approximation = .063, comparative fit index = .93, Tucker-Lewis index = .91, and standardized root mean squared residual = .06). Negative mental health outcomes significantly decreased by problem-focused coping (β = −5.16, 95% confidence interval [CI] = −9.56, −.77, p = .021) and significantly increased by passive coping (β = 4.72, 95% CI = 1.24, 8.19, p = .008). Conclusions: Abused women used multifaceted types of coping. Both problem-focused and passive coping mediated the IPV-mental health outcomes link. The findings reinforced the importance of helping abused women find practical ways to cope with IPV.
