RESUMO
This study applied self-determination theory (SDT) as a psychological framework to examine whether psychological need support and autonomous motivation are predictive of sports injury preventive behaviors and the incidence of sports injuries. 2042 secondary school students (mean age = 14.33, male = 44.3%) from China completed a survey of the study variables (using established scales) at three time points (baseline, 1-month follow-up, 3-month follow-up). Structural equation modeling examined the core tenets of SDT by testing if the change-scores of the SDT variables (i.e., psychological need support from PE teachers, students' motivation, and students' behavioral adherence) between baseline and 1-month follow-up, were predictive of sports injury incidence assessed at 3-month follow-up. Our model demonstrated acceptable goodness-of-fit parameters (CFI = 0.97, TLI = 0.96, RMSEA = 0.03, and SRMR = 0.05). The relationships between psychological need support, autonomous motivation, and behavioral adherence were both positive and significant. These SDT variables predicted the future incidence of sports injuries following the motivational pathways of SDT. Our study provides evidence of the predictive power of SDT variables on sports injury preventive behaviors and the incidence of sports injuries: Students who perceive their PE teachers as psychological need supportive possess higher autonomous motivation and behavioral adherence towards sports injury prevention, and are also less likely to encounter sports injuries in the future.

BACKGROUND: Adversity coping capability (ACC) is important amid the COVID-19 pandemic. We examined the associations of ACC as measured by our one-item ACC scale (ACC-1) with mental health, family well-being and validity of ACC-1 in Hong Kong. METHODS: A cross-sectional survey was conducted on Hong Kong Chinese adults aged ≥ 18 years by landline, mobile phone, and online survey from February to March 2021, when the fourth wave of COVID-19 was under control. ACC-1 consisted of the question: "How do you rate your capability to cope with adversities?" with higher scores (0-10) indicating stronger ACC. The associations of ACC with socioeconomic characteristics, resilience, mental health, and family wellbeing were examined by linear regression coefficients (ßs). Data were weighted by sex, age, and education of the general population. RESULTS: Of 7441 respondents, after weighing, 52.2% were female and 79.1% were aged 18 to 64 years. ACC-1 showed good construct validity, with higher ACC being associated with higher levels of resilience (adjusted ß = 0.29), personal happiness (0.55), family happiness (0.42), family wellbeing (0.41), and family communication quality (0.41), and lower levels of depressive symptoms (-0.30), anxiety (-0.30), loneliness (-0.15); incremental validity with additional contributions of ACC to mental health and family wellbeing; and known-group validity with older age and favorable socioeconomic characteristics showing higher ACC (all P < 0.02). Females (mean ± standard deviation: 6.04 ± 1.82 vs 6.15 ± 1.96 [male]) and unemployed respondents (5.30 ± 1.99 vs 6.11 ± 2.03 [in paid employment]) had lower ACC (all P ≤ 0.02). CONCLUSIONS: We have first shown that stronger ACC was associated with better mental health and family wellbeing, and the results support ACC-1 as a simple and valid measure of ACC.

OBJECTIVE: To investigate the effects of rehabilitation either before or after operation for lung cancer on postoperative pulmonary complications and the length of hospital stay. DATA SOURCES: MEDLINE, Cochrane Central Register of Controlled Trials, Web of Science, CINAHL Plus, SPORTDiscus, PsycInfo and Embase were searched from inception until June 2021. REVIEW METHODS: Inclusion criteria were patients scheduled to undergo or had undergone operation for lung cancer, randomised controlled trials comparing rehabilitative interventions initiated before hospital discharge to usual care control. Two reviewers independently assessed eligibility, extracted data and risks of bias. Pooled odds ratios (ORs) or standardised mean differences (SMDs) with 95% Confidence Intervals (CI) were estimated using random-effects meta-analyses. RESULTS: Twenty-three studies were included (12 preoperative, 10 postoperative and 1 perioperative), with 2068 participants. The pooled postoperative pulmonary complication risk and length of hospital stay were reduced after preoperative interventions (OR = 0.32; 95% CI = 0.22, 0.47; I2 = 0.0% and SMD = -1.68 days, 95% CI = -2.23, -1.13; I2 = 77.8%, respectively). Interventions delivered during the immediate postoperative period did not have any significant effects on either postoperative pulmonary complication or length of hospital stay (OR = 0.85; 95% CI = 0.56, 1.29; I2 = 0.0% and SMD = -0.23 days, 95% CI = -1.08, 0.63; I2 = 64.6%, respectively). Meta-regression showed an association between a higher number of supervised sessions and shorter hospital length of stay in preoperative studies (ß = -0.17, 95% CI = -0.29, -0.05). CONCLUSION: Preoperative rehabilitation is effective in reducing postoperative pulmonary complications and length of hospital stay associated with lung cancer surgery. Short-term postoperative rehabilitation in inpatient settings is probably ineffective.

BACKGROUND: Convenient and quality family communication improves family functioning and well-being. Using mobile instant messaging (IM) for family communication is increasingly popular, but its association with family functioning and family well-being has not been reported. OBJECTIVE: The aim of this study was to examine the association of the use of family IM chat groups with family functioning and well-being, and the mediating effect of family communication quality among Chinese adults in Hong Kong. METHODS: We analyzed data from the Family and Health Information Trend Survey (FHInTS), a territory-wide, probability-based telephone survey conducted in 2017. The quality of family communication, family functioning, and well-being was assessed using the Family Communication Scale; Family Adaptation, Partnership, Growth, Affection, and Resolve (APGAR) Scale; and Family Well-Being Scale (family heath, harmony, and happiness), respectively. Respondents also reported the number of family IM chat groups (0, 1, 2, ≥3), and numbers of IM messages received (<1, 1-2, 3-10, 11-20, >20) and sent (<1, 1-2, 3-10, 11-20, >20) daily. The frequency of family IM chat interaction (range 0-8) was calculated by combining the number of messages received from and sent to the family IM chat groups daily. Covariates included sociodemographic characteristics and the frequency of family face-to-face communication (often, sometimes, seldom, or never). Data were weighted by sex, age, and education of the general population. Adjusted ß coefficients of family functioning and well-being in relation to having a family IM chat group, and numbers of messages received and sent were calculated. The mediation effects of family communication on these associations were assessed, controlling for the covariates. RESULTS: A random sample of 1638 Chinese adults (45.6% men; 78.1% aged 25 to 64 years) were interviewed (response rate: 74.4%). Female, younger age, being married or cohabiting, higher education, higher income, better family functioning, and well-being were associated with having at least one family IM chat group (all P<.01). Higher scores of family communication, family APGAR, and family well-being were associated with having more family IM chat groups and more messages received from and sent to family IM chat groups daily (all P for trend <.01). More frequent family IM chat interaction was associated with higher scores of family communication, family APGAR, and family well-being (ß=.16-.83, all P for trend <.001). The associations of family IM chat interaction with family functioning and well-being were moderately (51.0%-59.6%) mediated by family communication. CONCLUSIONS: Use of a family IM chat group was associated with higher family functioning and well-being, and the association was partially mediated by family communication.

BACKGROUND: Electronic devices (eDevices) may have positive or negative influences on family communication and well-being depending on how they are used. OBJECTIVE: We examined eDevice use during family time and its association with the quality of family communication and well-being in Hong Kong Chinese adults. METHODS: In 2017, a probability-based 2-stage random sampling landline telephone survey collected data on eDevice use in daily life and during family time (eg, family dinner) and the presence of rules banning eDevice use during family dinner. Family communication quality was rated from 0 to 10 with higher scores being favorable. Family well-being was calculated as a composite mean score of 3 items each using the same scale from 0 to 10. The associations of family communication quality and well-being with eDevice use in daily life and during family time were estimated using beta-coefficient (ß) adjusting for sociodemographics. The mediating role of family communication quality in the association between eDevice use and family well-being was analyzed. RESULTS: Of the 2064 respondents (mean age 56.4 [SD 19.2] years, 1269/2064 [61.48%] female), 1579/2059 (76.69%) used an eDevice daily for a mean of 3.6 hours (SD 0.1) and 257/686 (37.5%) used it for 30+ minutes before sleep. As much as 794/2046 (38.81%) often or sometimes used an eDevice during family time including dinner (311/2017, 15.42%); 713/2012 (35.44%) reported use of an eDevice by family members during dinner. Lower family communication quality was associated with hours of eDevice use before sleep (adjusted ß=-.25; 95% CI -0.44 to -0.05), and often use (vs never use) of eDevice during family dinner by oneself (adjusted ß=-.51; 95% CI -0.91 to -0.10) and family members (adjusted ß=-.54; 95% CI -0.79 to -0.29). Similarly, lower family well-being was associated with eDevice use before sleep (adjusted ß=-.26; 95% CI -0.42 to -0.09), and often use during family dinner by oneself (adjusted ß=-.48; 95% CI -0.83 to -0.12) and family members (adjusted ß=-.50; 95% CI -0.72 to -0.28). Total ban of eDevice use during family dinner was negatively associated with often use by oneself (adjusted odds ratio 0.49; 95% CI 0.29 to 0.85) and family members (adjusted odds ratio 0.41; 95% CI 0.28, 0.60) but not with family communication and well-being. Lower family communication quality substantially mediated the total effect of the association of eDevice use time before sleep (61.2%) and often use at family dinner by oneself (87.0%) and by family members (67.8%) with family well-being. CONCLUSIONS: eDevice use before sleep and during family dinner was associated with lower family well-being, and the association was substantially mediated by family communication quality. Our results suggest that interventions on smart use of eDevice may improve family communication and well-being.

OBJECTIVE: To estimate the association between occupational polycyclic aromatic hydrocarbon (PAH) exposure and female breast cancer. METHODS: Lifetime work histories for 1130 cases and 1169 controls from British Columbia and Ontario (Canada) were assessed for PAH exposure using a job-exposure matrix based on compliance measurements obtained during US Occupational Safety and Health Administration workplace safety inspections. RESULTS: Exposure to any level of PAHs was associated with an increased risk of breast cancer (OR=1.32, 95% CI: 1.10 to 1.59), as was duration at high PAH exposure (for >7.4 years: OR=1.45, 95% CI: 1.10 to 1.91; ptrend=0.01), compared with women who were never exposed. Increased risk of breast cancer was most strongly associated with prolonged duration at high occupational PAH exposure among women with a family history of breast cancer (for >7.4 years: OR=2.79, 95% CI: 1.25 to 6.24; ptrend<0.01). CONCLUSIONS: Our study suggests that prolonged occupational exposure to PAH may increase breast cancer risk, especially among women with a family history of breast cancer.

PURPOSE: The association between high mammographic density (MD) and elevated breast cancer risk is well established. However, the role of absolute non-dense area remains unclear. We estimated the effect of the mammographic non-dense area and other density parameters on the risk of breast cancer. METHODS: This study utilizes data from a population-based case-control study conducted in Greater Vancouver, British Columbia, with 477 female postmenopausal breast cancer cases and 588 female postmenopausal controls. MD measures were determined from digitized screening mammograms using computer-assisted software (Cumulus). Marginal odds ratios were estimated by inverse-probability weighting using a causal diagram for confounder selection. Akaike information criteria and receiver operating characteristic curves were used to assess the goodness of fit and predictive power of unconditional logistic models containing MD parameters. RESULTS: The risk of breast cancer is 60% lower for the highest quartile compared to the lowest quartile of mammographic non-dense area (marginal OR 0.40, 95% CI 0.26-0.61, p-trend < 0.001). The cancer risk almost doubles for the highest quartile compared to the lowest quartile of dense area (marginal OR 1.81, 95% CI 1.19-2.43, p-trend < 0.001). For the highest quartile of percent density, breast cancer risk was more than three times higher than for the lowest quartile (marginal OR 3.15, 95% CI 1.90-4.40, p-trend < 0.001). No difference was seen in predictive accuracy between models using percent density alone, dense area alone, or non-dense area plus dense area. CONCLUSIONS: In this study, non-dense area is an independent risk factor after adjustment for dense area and other covariates, inversely related with the risk of breast cancer. However, non-dense area does not improve prediction over that offered by percent density or dense area alone.

PURPOSE: Obstructive sleep apnea (OSA) is highly associated with type 2 diabetes mellitus (DM), and treatment of OSA may have a positive impact on cardiometabolic profile. This study investigates the effects of continuous positive airway pressure (CPAP) treatment on glycemic control and cardiometabolic parameters in patients with diabetes. METHODS: Diabetic patients, who were newly diagnosed of OSA with an apnea hypopnea index (AHI) ≥15 and HbA1c ≥7%, were randomly assigned to either CPAP treatment or no treatment (control) for 3 months. Measurements included HbA1c, blood pressure, fasting glucose and lipids, urinary albumin, and peripheral arterial tonometry (to assess endothelial function). RESULTS: Sixty-four patients (52 men) were randomized, with mean (±SD) age of 55.0 ± 9.6 years, body mass index of 29.9 ± 5.3 kg/m2, HbA1c of 8.1 ± 1.1%, and AHI of 45.3 ± 23.2 events/h. In the intention-to-treat analysis, no significant change in HbA1c but reduction of systolic (10 mmHg (-18 to -2), p < 0.05) and diastolic (6 mmHg (-11 to -1), p < 0.05) blood pressures were found in the CPAP group compared to the control group. Excluding those with medication changes or initiated dietary program during the study period and those who dropped out, CPAP treatment decreased HbA1c (intervention group, n = 27; control group, n = 26) by 0.4% (-0.7 to -0.1), p = 0.027. CONCLUSIONS: In patients with type 2 DM and moderate to severe OSA, 3 months of CPAP therapy did not decrease HbA1c but lowered systolic and diastolic blood pressures. In view of a potentially limited effect size of CPAP treatment on glycemic control, sample size estimation for future randomized controlled studies must make adequate allowance for influence from external factors of medications/diet and CPAP use.

Studies of vitamin D-related genetic variants and breast cancer have been inconsistent. This study aimed to investigate associations of vitamin D-related polymorphisms and breast cancer risk among European and East Asian women and potential interactions with menopausal status and breast tumour subtypes. Data from a case-control study of breast cancer (1037 cases and 1050 controls) were used to assess relationships between 21 polymorphisms in two vitamin D-related genes (GC and VDR) and breast cancer risk. Odds ratios were calculated in stratified analyses of European and East Asian women, using logistic regression in an additive genetic model. An interaction term was used to explore modification by menopausal status. Polytomous regression was used to assess heterogeneity by breast tumour subtype. False discovery rate adjustments were conducted to account for multiple testing. No association was observed between GC or VDR polymorphisms and breast cancer risk. Modification of these relationships by menopausal status was observed for select polymorphisms in both Europeans (VDR rs4328262 and rs11168292) and East Asians (GC rs7041 and VDR rs11168287). Heterogeneity by tumour subtype was seen for three VDR polymorphisms (rs1544410, rs7967152 and rs2239186) among Europeans, in which associations with ER-/PR-/HER2+ tumours, but not with other subtypes, were observed. In conclusion, associations between vitamin D-related genetic variants and breast cancer were not observed overall, although the relationships between vitamin D pathway polymorphisms and breast cancer may be modified by menopausal status and breast tumour subtype.

BACKGROUND: Endothelial dysfunction has been recognized to occur in the context of obstructive sleep apnea (OSA) or tobacco smoking. However, the deleterious effect on vascular function with concurrence of both conditions is largely unknown. OBJECTIVE: To investigate whether the concurrence of OSA and smoking poses an additive detriment to endothelial dysfunction. METHODS: Chinese men without a history of chronic medical illness were invited to complete a questionnaire including smoking pack-year exposure, polysomnography and peripheral arterial tonometry (PAT) for endothelial function. Serum 8-isoprostane, advanced oxidation protein products (AOPP) and monocyte chemo-attractant protein-1 (MCP-1) were measured. RESULTS: 114 men were successfully enrolled. PAT ratio, adjusted for age and body mass index, correlated inversely with overall severity of OSA: apnea-hypopnea index (AHI), r = -0.160 (p = 0.092); oxygen desaturation index, r = -0.214 (p = 0.024); duration of oxygen saturation <90%, r = -0.219 (p = 0.020); and minimum oxygen saturation, r = 0.250 (p = 0.008). The PAT ratio decreased with increasing pack-year group (p = 0.018). It was lower with concurrent smoking history and moderate-severe OSA (AHI ≥15/h) compared to having one or neither factor (p = 0.011). Serum levels of 8-isoprostane and AOPP were positively related to severity of OSA, while MCP-1 correlated with smoking quantity. Multiple linear regression analyses showed that severity of intermittent hypoxia, MCP-1 and pack-year exposure were independent predictors of PAT ratio. CONCLUSION: While OSA, in particular intermittent hypoxemia, and tobacco smoking were independent risk factors, the concurrence of moderate-severe OSA and smoking was associated with the most severe impairment in endothelial function.

PURPOSE: Our aim was to determine the pathway underlying the effects of continuous positive airway pressure (CPAP) adherence on intimate relationship with bed partner in men with obstructive sleep apnea (OSA). We hypothesized that CPAP with good adherence affected the intimate relationship with bed partner directly and indirectly, and it was mediated through daytime sleepiness and activity level in men with OSA. METHODS: Data were obtained from an education program for enhancing CPAP adherence. Men who were newly diagnosed of OSA and CPAP therapy naïve were recruited in a tertiary teaching hospital. RESULTS: Self-reported quality of life [Functional Outcomes of Sleep Questionnaire], daytime sleepiness [Epworth Sleepiness Scale (ESS)], and negative emotion symptoms [depression, anxiety, stress scale] were assessed before and after CPAP treatment at 1-year assessment. Seventy-three men were included in the data analysis, with a mean ± SD age of 52 ± 10 years, body mass index of 29.0 ± 5.2 kg/m(2), ESS of 9.5 ± 5.6, and median [interquartile range(IR)] apnea and hypopnea index of 31 (21, 56) events/h. The median (IR) CPAP daily usage was 4.3(0, 6.1) h/day. From the path analysis, CPAP therapy was shown to improve intimate relationship directly (ß = 0.185) and indirectly (ß = 0.050) by reducing daytime sleepiness and increasing activity level. However, negative emotion symptoms were not the mediators between CPAP adherence and the intimate relationship. CONCLUSIONS: CPAP therapy with good adherence is related directly and indirectly to a better intimate relationship with bed partner in men with OSA. It was possibly attributed to reduced daytime sleepiness and increased activity level.

PURPOSE: Physical activity reduces breast cancer risk, although most evidence is for activity in the moderate-to-vigorous intensity range. The effect of light intensity physical activity (LIPA) is unknown. We aimed to determine the association between self-reported lifetime LIPA and pre- and post-menopausal breast cancer risk. Our secondary objective was to analyze risk stratified by estrogen and progesterone tumor receptor status. METHODS: Data were from a case-control study of 1,110 incident breast cancer cases (388 pre-menopausal; 722 post-menopausal) and 1,172 controls (442 pre-menopausal; 730 post-menopausal) recruited at two Canadian sites. Lifetime leisure-time, household, and occupational physical activity and covariates were assessed by questionnaire. Mean minutes per day of LIPA for each of the age periods 12-17, 18-34, 35-49, ≥50, and the total lifetime were calculated. Odds ratios were calculated using unconditional logistic regression for overall breast cancer risk and using polytomous logistic regression for estrogen receptor (ER)/progesterone receptor (PR)-defined tumor subtypes and were adjusted for moderate-to-vigorous physical activity and other confounders. RESULTS: LIPA was not associated with breast cancer risk at any age period across the life course: odds ratio (OR) = 0.81; 95 % CI 0.53-1.24 for pre-menopausal women and OR = 0.87; 95 % CI 0.64-1.19 for post-menopausal women in the highest vs. lowest categories of total lifetime LIPA. No heterogeneity in risk by ER/PR tumor status was observed. CONCLUSIONS: Our results suggest that light intensity physical activity is not associated with breast cancer risk reduction. This finding is important for physical activity recommendations for breast cancer prevention.

Background: Promoting COVID-19 prevention is key to pandemic control and innovative interventions can help communicate reliable science to the public. Under the Hong Kong Jockey Club SMART Family-Link Project, we developed and evaluated a pilot intervention for promoting COVID-19 prevention through a web-based family game, guided by the Theory of Planned Behavior and a strength-based approach. Methods: The "SMART Epidemic prevention" pilot theme was launched to the public on September 21, 2020 for 4 weeks. The game had two parts: (i) strength recognition and (ii) quiz questions on knowledge and behaviors about COVID-19 prevention. Simple baseline, in-game, and postgame evaluation assessed players' perceived knowledge, behaviors, family well-being, game satisfaction, and perceived benefits. Results: Of 86 registered families, 55 played actively, including 212 players (51% female, 35% aged below 18) who self-identified as children (44%), parents (39%), and grandparents (11%). In weeks 1 and 4, an average of 7 and 18 game rounds were played per family, and 86.6% and 75.9% of rounds had perfect (2) behavior matches. Postgame evaluation with 51 families showed improvements in epidemic prevention knowledge and behaviors, family communication, family happiness (all P < 0.001), and family relationship (P = 0.002) with small effect sizes (0.15-0.29). Overall game satisfaction was rated 4.49 (scale of 1-5). Ninety-four percent of families shared knowledge from the game with others. Conclusions: Our pilot web-based family game first showed preliminary evidence on enhancing COVID-19 prevention knowledge and behaviors, and family well-being, with participants recognizing family strengths, reporting high satisfaction and various perceived benefits, and showing sustained gameplay. Trial Registration: The research protocol was registered at the National Institutes of Health (Identifier No. NCT04550065) on September 16, 2020.

Excessive sugar intake poses a significant risk factor for non-communicable diseases. A positive healthy eating (PHE) intervention was developed to promote low-sugar dietary practices in families. The PHE intervention capitalized on positive psychological constructs to overcome barriers to health behavior change by helping families associate feelings of joy, gratitude, and savoring with healthy eating. In a cluster randomized controlled trial, 1983 participants from 1467 families were recruited in Hong Kong. PHE included a core and booster session. Data were collected at pre-intervention, post-intervention, and at 1-month and 3-month follow-up. Compared to the control, PHE showed greater increase in intention to change at post-intervention, engagement in low-sugar dietary practices individually and with family members at 3-month follow-up, and greater reduction in sugar-sweetened beverage intake at 1-month and 3-month follow-up. Intentions to change mediated PHE's effects on low-sugar dietary practices. Focus group interviews revealed the behavior-change process and family quality of life.
RESUMO
Moderate-to-vigorous intensity physical activity (MVPA) reduces breast cancer risk, although the effects of MVPA in different settings across the life course and how they may differ by menopausal status are unclear. This gap was addressed using data from a case-control study of 1,110 incident breast cancer cases and 1,172 cancer-free controls, frequency matched by age, from Vancouver and Kingston, Canada. In Vancouver, cases were recruited from the British Columbia Cancer Registry and controls from the Screening Mammography Program of British Columbia and in Kingston cases and controls were recruited from a breast assessment center. Lifetime leisure-time, household, and occupational MVPA energy expenditures were assessed in an open-ended questionnaire and mean weekly metabolic equivalent hours (MET-h/week) were calculated for the age periods 12-17, 18-34, 35-49, and ≥50 years and for the total lifetime. Odds ratios were estimated separately for pre- and for post-menopausal women using unconditional logistic regression. Among post-menopausal women, each of >22.9 MET-h/week of mean lifetime leisure-time MVPA (equivalent to running for 3 h) and >61.1 MET-h/week of mean lifetime household MVPA (equivalent to 24 h of moderate household work) reduced breast cancer risk by 40 %, compared to 0 MET-h/week of each. The respective ORs were 0.63 (95 % CI 0.42-0.94) and 0.58 (95 % CI 0.43-0.79). Among post-menopausal women, leisure-time MVPA after age 35 was more strongly associated with reduced breast cancer risk than MVPA in early life, while household MVPA was associated with reduced risk at all adulthood age periods.

OBJECTIVES: Long-term night work has been suggested as a risk factor for breast cancer; however, additional studies with more comprehensive methods of exposure assessment to capture the diversity of shift patterns are needed. As well, few previous studies have considered the role of hormone receptor subtype. METHODS: Relationships between night shift work and breast cancer were examined among 1134 breast cancer cases and 1179 controls, frequency-matched by age in Vancouver, British Columbia, and Kingston, Ontario. Self-reported lifetime occupational histories were assessed for night shift work, and hormone receptor status obtained from tumour pathology records. RESULTS: With approximately one-third of cases and controls ever employed in night shift work, associations with duration demonstrated no relationship between either 0-14 or 15-29 years, while an association was apparent for ≥30 years (OR=2.21, 95% CI 1.14 to 4.31). This association with long-term night shift work is robust to alternative definitions of prolonged shift work, with similar results for both health and non-health care workers. CONCLUSIONS: Long-term night shift work in a diverse mix of occupations is associated with increased breast cancer risk and not limited to nurses, as in most previous studies.

BACKGROUND: Cognitive behavioral therapy for insomnia (CBT-I) as a first-line treatment may improve insomnia in pregnant women. The efficacy of the components, modalities, doses, and effectiveness of CBT-I in pregnant women at follow-up remains unclear. OBJECTIVES: To assess the effectiveness of CBT-I in pregnant women and identify effective intervention components, modalities, and doses. DESIGN: Systematic review and meta-analysis. METHODS: Six English databases (PubMed, Embase, Cochrane Library, Web of Science, PsycINFO, CINAHL) and four Chinese databases (CNKI, WanFang Data, SinoMed, and CQVIP) were searched from inception to 10 January 2023. Randomized controlled trials (RCTs) on CBT-I in pregnant women with outcomes of insomnia severity measured by Insomnia Severity Index (ISI) or sleep quality measured by Pittsburgh Sleep Quality Index (PSQI). Two reviewers independently completed records selection, data extraction, and study quality assessment. The fixed-effect or random-effect model was used for pooled analyses. Subgroup analyses were conducted based on different delivery types and intervention duration. The GRADE approach was used to evaluate the certainty of the evidence. Narrative analyses were used when meta-analysis was not appropriate. Mean differences with 95% CIs of insomnia severity and sleep quality scores were the main outcomes (greater scores indicating greater severity). RESULTS: Nine RCTs (N = 978) meeting the inclusion criteria were included. These trials included individual- (n = 6) or group-based (n = 3) interventions, which were conducted via face-to-face (n = 5), digital (n = 3) or telephone and e-mail (n = 1) formats. Six studies stated intervention components specific to pregnant women. CBT-I improved insomnia severity (MD = -2.69, 95% CI: -3.41 to -1.96, P ï¼ 0.001, high quality evidence; MD = -3.69, 95% CI: -5.91 to -1.47, P = 0.001, moderate quality evidence) and sleep quality (MD = -2.85, 95% CI: -4.73 to -0.97, P = 0.003, moderate quality evidence; MD = -1.88, 95% CI: -2.89 to -0.88, P ï¼ 0.001, moderate quality evidence) immediately after intervention (ï¼1-month) and at short-term (≥1 month to ï¼6 months) follow-up, respectively. Two RCTs reported no effectiveness on insomnia severity at medium-term (≥6 months toï¼12 months) follow-up. Only 1 RCT showed reduced insomnia severity at long-term (≥12 months) follow-up. One RCT reported no effectiveness in sleep quality at medium-term follow-up and effectiveness at long-term follow-up was not reported. CONCLUSIONS: Pregnant women may benefit from CBT-I to improve short-term insomnia, but long-term effectiveness is unclear. Rigorous RCTs with long-term follow-ups are warranted.

Objective: Family services are open to the community at large as well as vulnerable groups; however, little is known about the willingness of communities to attend such services. We investigated the willingness and preferences to attend family services and their associated factors (including sociodemographic characteristics, family wellbeing, and family communication quality) in Hong Kong. Methods: A population-based survey was conducted on residents aged over 18 years from February to March 2021. Data included sociodemographic characteristics (sex, age, education, housing type, monthly household income, and the number of cohabitants), willingness to attend family services to promote family relationships (yes/no), family service preferences (healthy living, emotion management, family communication promotion, stress management, parent-child activities, family relationship fostering, family life education, and social network building; each yes/no), family wellbeing, and family communication quality (both scores 0-10). Family wellbeing was assessed using the average scores of perceived family harmony, happiness and health (each score 0-10). Higher scores indicate better family wellbeing or family communication quality. Prevalence estimates were weighted by sex, age and educational level of the general population. Adjusted prevalence ratios (aPR) for the willingness and preferences to attend family services were calculated in relation to sociodemographic characteristics, family wellbeing, and family communication quality. Results: Overall, 22.1% (1,355/6,134) and 51.6% (996/1,930) of respondents were willing to attend family services to promote relationships or when facing problems, respectively. Older age (aPR = 1.37-2.30, P < 0.001-0.034) and having four or more cohabitants (aPR = 1.44-1.53, P = 0.002-0.003) were associated with increased aPR of willingness for both situations. Lower family wellbeing and communication quality were associated with lower aPR for such willingness (aPR = 0.43-0.86, P = 0.018-<0.001). Lower family wellbeing and communication quality were associated with preferences for emotion and stress management, family communication promotion, and social network building (aPR = 1.23-1.63, P = 0.017-<0.001). Conclusions: Lower levels of family wellbeing and communication quality were associated with unwillingness to attend family services and preferences for emotion and stress management, family communication promotion, and social network building.

Background: The COVID-19 pandemic has greatly challenged all public social services, particularly home-based community care services (HBCCS). Aberdeen Kai-fong Association (AKA) is a non-government organization (NGO) in Hong Kong that systematically manages the challenges to HBCCS. This paper presents a practical example of the implementation and evaluation of the risk management process for HBCCS. Methods: Mixed-method design was used to evaluate the implementation of the risk management process in encountering the challenges from existing and potential problems to maintain and enhance HBCCS in four major areas amidst the pandemic. A cross-sectional questionnaire survey and three qualitative focus group interviews were conducted by AKA from 30 December 2021 to 12 March 2022 to collect staff feedback on the institutional risk management process in four areas. Results: 109 HBCCS staff members (69% aged 40 years or above; 80% female) completed the questionnaire survey. For resource arrangement and staff training, over 90% of the participants agreed (including strongly agreed) that they had sufficient and reliable personal protective equipment and clear infection control guideline and effective training. Over 80% agreed they had safe working space and effective manpower allocation. However, only 75% agreed they had received emotional support from the organization. Over 90% agreed that the basic services were maintained for service continuation and enhancement, the service users and their families trusted the organization, and the provided services were adjusted according to users' needs. 88% agreed that the organization had obtained support from the neighborhood. For communication among stakeholders, over 80% agreed they had open discussions with the senior management team, and the senior management team was willing to listen. Twenty-six staff members joined the three focus group interviews. The qualitative findings corroborated the quantitative results. Staff appreciated the organisation's work to enhance staff safety and continue advancing services during this difficult period. Regular in-service training, updated information and guidelines to staff, and proactive phone calls to service users, especially the elderly, were suggested to enhance the quality of services. Conclusions: The paper could help NGOs and others encountering management challenges in community social services in diverse settings amidst the pandemic and beyond.

Background: The COVID-19 pandemic drives psychological distress. Previous studies have mostly focused on individual determinants but overlooked family factors. The present study aimed to examine the associations of individual and family factors with psychological distress, and the mediating effect of individual fear and the moderating role of household income on the above associations. Methods: We conducted a population-based cross-sectional survey on Chinese adults in Hong Kong from February to March 2021 (N = 2,251) to measure the independent variables of anti-epidemic fatigue, anti-epidemic confidence, individual and family members' fear of COVID-19, and family well-being (range 0-10), and the dependent variable of psychological distress (through four-item Patient Health Questionnaire, range 0-4). Results: Hierarchical regression showed that anti-epidemic fatigue was positively (ß = 0.23, 95% CI [0.18, 0.28]) while anti-epidemic confidence was negatively (ß = -0.29, 95% CI [-0.36, -0.22]) associated with psychological distress. Family members' fear of COVID-19 was positively (ß = 0.11, 95% CI [0.05, 0.16]) while family well-being was negatively (ß = -0.57, 95% CI [-0.63, -0.51]) associated with psychological distress. Structural equation model showed that individual fear mediated the above associations except for family well-being. Multi-group analyses showed a non-significant direct effect of anti-epidemic confidence and a slightly stronger direct effect of family well-being on psychological distress among participants with lower incomes, compared to those with higher incomes. Conclusion: We have first reported the double-edged effect of family context on psychological distress, with the positive association between family members' fear of COVID-19 and psychological distress fully mediated by individual fear and the negative association between family well-being and psychological distress moderated by income level. Future studies are warranted to investigate how the contagion of fear develops in the family and how the inequality of family resources impacts family members' mental health amid the pandemic.
