Abstract: To explore the association between maternal intimate partner abuse (IPA) and their children's health-related quality of life (HRQOL) and behavioural problem, and to establish a mediation model and investigate the mediating role of mothers' HRQOL on this association. A cross-sectional study was conducted on 197 mothers of 227 children (112 boys and 115 girls) from low-income Chinese families. The mothers were asked to complete the 5-item abuse assessment screen questionnaire for the presence of IPA, the Chinese (Hong Kong) version of 12-item Short-Form Health Survey (SF-12) for their HRQOL and a structured socio-demographics questionnaire. One of the parents completed the Child Health Questionnaire-Parent Form-50 (CHQ-PF50) and the strengths and difficulties questionnaire (SDQ) to report on their children's HRQOL and behavioural problems, respectively. The mediating effect of the maternal HRQOL on the relationship between maternal IPA status and their children's behavioural problems and HRQOL was tested using Baron and Kenney's multistage regression approach and bootstrapping method. Thirty-five of the 197 mothers reported IPA (17.8%). Children whose mothers had experienced IPA had lower scores in the CHQ-PF50 mental health, parental impact-emotional, family activities and family cohesion subscales, and the psychosocial summary score compared to children of mothers who reported no IPA they also had more emotional, conduct and hyperactivity/inattention problems and higher total difficulties scores measured by the SDQ. Maternal mental HRQOL was a mediator on the relationship between maternal IPA status and their children's behavioural problems and psychosocial HRQOL. IPA experienced by mothers had significant negative impacts on their children's HRQOL and behaviours, which was mediated by maternal mental HRQOL.

Abstract: To investigate the association between daytime napping and prevalent/incident diabetes mellitus (DM) based on systematic review and meta-analytic data. The electronic databases of Embase, Medline, Pubmed and Web of Science were searched. Relevant studies were extracted by two reviewers independently. The associations between daytime napping (irrespective of duration), long nap (≥1 h/day) and short nap (<1 h/day), and risk of DM were assessed according to study types. Overall estimates were pooled using either fixed- or random-effect with inverse variance meta-analysis. Heterogeneity of included studies was assessed using the I Ten studies (four cross-sectional and six longitudinal cohort) comprising a total of 304,885 in iduals and 20,857 cases of DM were included in the systematic review, with an average napping prevalence of 47%. Nappers were found to have increased risk of DM in both cross-sectional and cohort studies. However, significant heterogeneity was present. Long nap (≥1 h/day) was associated with both prevalent and incident DM in particular, those with a daily nap over 1 h had a 31% increased risk of developing DM during follow-up (95% confidence interval: 2-67%). Conversely, no such association was found in in iduals with short naps (<1 h/day) in cohort studies. Long daytime napping over 1 h per day was associated with increased risk of both prevalent and incident DM. Further studies are needed to confirm the findings.

Abstract: To assess health-related quality of life (HRQOL) among Chinese adults from low-income households in Hong Kong, and to explore any threshold of household income that impaired HRQOL. A cross-sectional analysis was conducted on 298 adults from low-income families when they enrolled into a cohort study between 2012 and 2014. HRQOL was measured by the 12-item Short-Form Health Survey-version 2 (SF-12v2). Their mean SF-12v2 subscale and summary scores were compared with those of 596 age-sex-matched subjects randomly selected from a database of 2763 adults from the Hong Kong general population (ratio = 1:2). Multiple linear regressions were conducted to determine any association between monthly household income and HRQOL. Subjects from low-income households had significantly lower SF-12v2 bodily pain, general health, vitality and physical component summary (PCS) scores than the age-sex matched subjects from the general population. Subgroup analysis showed that a household income <50% of the median monthly household income in Hong Kong (HK$10 000 ≈ US$1290, i.e. poverty line in Hong Kong) was independently associated with poorer PCS and mental component summary (MCS) scores after adjustment for socio-demographics and co-morbidities. Chinese adults from low-income households had poorer HRQOL, and <50% of the median monthly household income seems to be the threshold for impairment of both physical and mental HRQOL. The findings support the current definition of the poverty line.

Abstract: The aim of this paper was to critically review the literature on the cost effectiveness of cancer screening interventions, and examine the incremental cost-effectiveness ratios (ICERs) that may influence government recommendations on cancer screening strategies and funding for mass implementation in the Hong Kong healthcare system. We conducted a literature review of cost-effectiveness studies in the Hong Kong population related to cancer screening published up to 2015, through a hand search and database search of PubMed, Web of Science, Embase, and OVID Medline. Binary data on the government's decisions were obtained from the Cancer Expert Working Group, Department of Health. Mixed-effect logistic regression analysis was used to examine the impact of ICERs on decision making. Using Youden's index, an optimal ICER threshold value for positive decisions was examined by area under receiver operating characteristic curve (AUC). Eight studies reporting 30 cost-effectiveness pairwise comparisons of population-based cancer screening were identified. Most studies reported an ICER for a cancer screening strategy versus a comparator with outcomes in terms of cost per life-years (55.6 %), or cost per quality-adjusted life-years (55.6 %). Among comparisons with a mean ICER of US$102,931 (range 800-715,137), the increase in ICER value by 1000 was associated with decreased odds (odds ratio 0.990, 0.981-0.999 p = 0.033) of a positive recommendation. An optimal ICER value of US$61,600 per effectiveness unit yielded a high sensitivity of 90 % and specificity of 85 % for a positive recommendation. A lower ICER threshold value of below US$8044 per effectiveness unit was detected for a positive funding decision. Linking published evidence to Government recommendations and practice on cancer screening, ICERs influence decisions on the adoption of health technologies in Hong Kong. The potential ICER threshold for recommendation in Hong Kong may be higher than those of developed countries.

Abstract: We aimed to determine the prospective association between baseline triglyceridaemic-waist phenotypes and diabetic mellitus incidence in in iduals with impaired fasting glucose seen in primary care. A cohort of 1101 participants (84.4% of the recruited in iduals) with impaired fasting glucose were recruited from three primary care clinics during regular follow-ups to monitor their chronic conditions. Baseline triglyceridaemic-waist phenotypes were ided into four groups: (1) normal waistline and triglyceride level (n = 252) (2) isolated central obesity (n = 518) (3) isolated high triglyceride level (n = 80) and (4) central obesity with high triglyceride level (i.e. hypertriglyceridaemic-waist phenotype) (n = 251). The presence of diabetes at follow-up was determined by fasting plasma glucose (≥ 7.0 mmol/l) and/or 2-h 75-g oral glucose tolerance test (≥ 11.1 mmol/l) and/or HbA After a mean follow-up period of 6.5 months (sd 4.7 months), the number of diabetes cases was significantly higher in the group with hypertriglyceridaemic-waist phenotype (52.2%) compared with the other three phenotype groups (group 1: 28.2% group 2: 34.6% group 3: 30.0%). Only the hypertriglyceridaemic-waist phenotype showed an increased risk of developing diabetes (hazard ratio 1.581, 95% CI 1.172-2.134 P = 0.003) compared with the group with normal waistline and triglyceride level after controlling for confounders. The combination of central obesity and hypertriglyceridaemia is associated with > 50% risk of progression to diabetes within 6 months among in iduals with impaired fasting glucose seen in primary care.

Abstract: A cross-sectional analysis of a dataset of 156 participants in a health assessment program explored whether negative emotional states mediated the association between intimate partner violence (IPV) and health-related quality of life (HRQoL). Compared with IPV screen-negative participants, those who screened positive had significantly lower HRQoL and significantly higher levels of depression, anxiety, and stress. The inverse associations between the presence of IPV and HRQoL were found to be mediated by depression, anxiety, and stress. Therefore, interventions to alleviate negative emotions in women suffering from IPV have the potential to be useful in improving their HRQoL.

Abstract: Chronic stress has adverse effects on health. Adults and children from low-income families are subject to multiple sources of stress. Existing literature about economic hardship mostly focuses on either adults or children but not both. Moreover, there is limited knowledge on the relationship between parental generalised stress and child health problems. This study aims to explore the bidirectional relationship between parental stress and child health in Chinese low-income families and to identify other modifiable factors influencing this relationship. This prospective cohort study will s le 254 low-income parent–child pairs and follow them up for 24 months with assessments at three time points (baseline, 12 and 24 months) on parental stress, health-related quality of life (HRQOL) and child health and behaviour using both subjective measures and objective physiological parameters. This study will collect data using standardised measures on HRQOL and behaviours of children as well as on HRQOL, mental health and stress levels of parents along with physiological tests of allostatic load and telomere length. The mediating or moderating effect of family harmony, parenting style and neighbourhood conditions will also be assessed. Data will be analysed using latent growth modelling and cross-lagged path analysis modelling to examine the bidirectional effect of parental stress and child health over time. Mediation and moderation analysis will also be conducted to examine the mechanism by which the variables relate. This study was approved by the institutional review board of the University of Hong Kong—the Hospital Authority Hong Kong West Cluster, reference no: UW 16-415. The study findings will be disseminated through peer-reviewed publications and international conferences. NCT03185273 Pre-results.

Abstract: Mothers with chronic diseases may have spillover effects on their children. The aim of this study was to estimate the spillover effects of mothers with chronic disease on their children's health-related quality of life (HRQOL) and behavior. A cross-sectional study was conducted on 255 mother-child pairs (130 boys and 125 girls, mean age 8.4 years) from low-income Chinese families. We asked the mothers to self-report any doctor-diagnosed chronic diseases, and evaluate their children's HRQOL and behaviors with the Child Health Questionnaire-Parent Form-50 (CHQ-PF50) and the Strengths and Difficulties Questionnaire (SDQ), respectively. Multiple linear regression analysis was conducted to assess the independent spillover effect of maternal chronic disease on children's HRQOL and behaviors, with adjustment for confounders. The differential impact of maternal physical and mental diseases was also investigated. Over one-third of mothers (n = 88, 34.5%) reported one or more doctor-diagnosed chronic diseases. Multiple linear regression analysis showed that children of mothers with chronic diseases had significantly lower CHQ-PF50 scores in the parental impact-time, parental impact-emotional, and family activities subscales and psychosocial summary scores, as well as more hyperactive and inattentive problems measured by SDQ after adjustment for confounders. Maternal mental and physical disease showed a differential impact on children's HRQOL and behavior. Chronic disease in mothers might exert adverse effects on their children's HRQOL and behaviors. The effects could differ by maternal physical or mental disease status. Special attention and support should be paid to children of mothers with chronic disease as these children are at an increased risk of poor HRQOL and problematic behaviors.
