Psychosocial treatment options for adolescents and young adults with alcohol use disorder: systematic review and meta-analysis.

Introduction: Psychosocial intervention is imperative for treating alcohol use disorder (AUD), but there is no comprehensive evidence regarding its effectiveness. Therefore, this study aimed to determine the effectiveness of psychosocial interventions in treating AUD amongadolescents and young adults. Methods: In this systematic review and meta-analysis, articles were searched from EMBASE, PubMed, Medline, CINAHL, Web of Science, PsycINFO, and Scopus. Also, articles were retrieved from gray literature. The quality of articles has been assessed using the Cochrane risk of bias assessment. Results: A total of 12 randomized controlled trials were included. Integrated family and CBT, CBT, guided self-change, and ecologically based family therapy had a mild effect in reducing alcohol use frequency. On the other hand, integrated motivational enhancement therapy and CBT (-0.71 [95% CI: -0.97, -0.45]) and common elements treatment approaches (4.5 [95% CI: 6.9, 2.2]) had the highest effect size for reducing alcohol use frequency and amount, respectively. In conclusion, most of the interventions had no significant effect on different drinking outcomes. Nonetheless, the effectiveness of combined interventions surpassed that of the single interventions. The effect of psychosocial interventions on abstinence was inconclusive. Therefore, future studies will explore alternative, newly emerged third-wave therapeutic approaches.

Hand Hygiene Education Components Among First-Year Nursing Students: A Cluster Randomized Clinical Trial.

Importance: Few studies have directly and objectively measured the individual and combined effects of multifaceted hand hygiene education programs. Objective: To evaluate the individual and combined immediate effects of an instructional video and hand scan images on handwashing quality, decontamination, and knowledge improvement. Design, Setting, and Participants: This cluster randomized clinical trial was conducted in June to July 2023 among first-year nursing students at a university in Hong Kong. The study used an intention-to-treat analysis. Intervention: Hand hygiene education sessions featuring an instructional video, hand scan images, or both. Main Outcomes and Measures: The primary outcome was the change in residue from fluorescent lotion remaining on participants' hands after handwashing before and after the intervention. The secondary outcomes included handwashing quality and knowledge of hand hygiene. Results: A total of 270 of 280 students (mean [SD] age, 19 [1] years; 182 [67.4%] female) participated in the trial (96.4% participation rate). Participants were randomized to a control group (66 participants), hand scan image group (68 participants), instructional video group (67 participants), and hand scan image with instructional video group (69 participants). All intervention groups had greater reductions in residue after the intervention compared with the control group, although none reached statistical significance (hand scan image group: 3.9 [95% CI, 2.0-5.8] percentage points; instructional video group: 4.8 [95% CI, 2.9-6.7] percentage points; hand scan image with instructional video: 3.5 [95% CI, 1.6-5.4] percentage points; control group: 3.2 [95% CI, 1.3-5.2] percentage points). The instructional video group showed a significant improvement in their handwashing performance, with a higher percentage of participants correctly performing all 7 steps compared with the control group (22.4% [95% CI, 13.1% to 31.6%] vs 1.5% [-7.9% to 10.9%]; P < .001). Hand scan images revealed that wrists, fingertips, and finger webs were the most commonly ignored areas in handwashing. Conclusions and Relevance: In this cluster randomized clinical trial of an education program for hand hygiene, a handwashing instructional video and hand scan images did not enhance the level of decontamination. The intervention group had improved handwashing techniques compared with the control group, a secondary outcome. Trial Registration: ClinicalTrials.gov Identifier: NCT05872581.

Effectiveness of a videoconferencing group-based dyad acceptance and commitment therapy on the quality of life of chronic heart failure patients and their family caregivers: A study protocol for a randomized controlled trial.

BACKGROUND: Chronic heart failure (CHF) poses a significant burden on both patients and their family caregivers (FCs), as it is associated with psychological distress and impaired quality of life (QOL). Acceptance and Commitment Therapy (ACT) supports QOL by focusing on value living and facilitates acceptance of psychological difficulties by cultivating psychological flexibility. A protocol is presented that evaluates the effectiveness of a dyad ACT-based intervention delivered via smartphone on QOL and other related health outcomes compared with CHF education only. METHODS: This is a single-center, two-armed, single-blinded (rater), randomized controlled trial (RCT). One hundred and sixty dyads of CHF patients and their primary FCs will be recruited from the Cardiology Department of a hospital in China. The dyads will be stratified block randomized to either the intervention group experiencing the ACT-based intervention or the control group receiving CHF education only. Both groups will meet two hours per week for four consecutive weeks in videoconferencing sessions over smartphone. The primary outcomes are the QOL of patients and their FCs. Secondary outcomes include psychological flexibility, psychological symptoms, self-care behavior, and other related outcomes. All outcomes will be measured by blinded outcome assessors at baseline, immediately post-intervention, and at the three-month follow-up. Multilevel modeling will be conducted to assess the effects of the intervention. DISCUSSION: This study is the first to adopt an ACT-based intervention for CHF patient-caregiver dyads delivered in groups via smartphone. If effective and feasible, the intervention strategy and deliverable approach could be incorporated into clinical policies and guidelines to support families with CHF without geographic and time constraints. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04917159. Registered on 08 June 2021.

Preliminary effects of a WeChat-based educational intervention on social participation among older adults in a community.

BACKGROUND: The social participation of older people should be encouraged, as it is fundamental to their well-being and the practice of aged care. Therefore, the ability of older persons to participate in society should be strengthened. OBJECTIVE: To evaluate the preliminary effects of a WeChat-based educational intervention on the social participation of community-dwelling older adults in China. METHODS: This study was a quasi-experimental design. Twenty-eight community-dwelling older adults participated in a WeChat-based educational intervention. The intervention contents included concepts and preparation of social participation, analysis of participation resources and capabilities, technological adaptation, emotional management, setting of to-do lists, etc. Social participation, self-worth and subjective well-being were measured via the WeChat application on smartphones at baseline, immediately after the intervention, and a 3-month follow-up. We analysed data using paired t-tests and analysis of variance (ANOVA). RESULTS: We found statistically significant improvements in social participation (active aging) (F = 4.408; p < .05) as well as the self-worth dimensions of moral worth (F = 4.135; p < .05) and psychological worth (F = 3.234; p < .05), and the negative-affect dimension of subjective well-being being decreased (F = 2.484; p < .05). CONCLUSIONS: The WeChat-based education intervention can effectively improve social participation and self-worth, and may provide effective preventive healthcare solutions for older adults in China. IMPLICATIONS FOR PRACTICE: The enormous value of the social participation of independent older adults must be recognised. Nurses can use smartphones to deliver health and social participation information in routine programs in aged care.

An integrated smoking cessation and alcohol intervention among Hong Kong Chinese young people: Study protocol for a feasibility randomized controlled trial.

INTRODUCTION: Young smokers always partake in both smoking and drinking. However, drinking undermines their likelihood to attempt quitting smoking or to successfully abstain from smoking. Hence, this trial will examine the feasibility of implementing an integrated smoking cessation and alcohol intervention in young Hong Kong Chinese people. Effect sizes of the integrated intervention (II) on self-reported and biochemically validated quit rates will also be calculated. METHODS: The study will be a three-arm randomized controlled trial in a convenience sample of 150 smokers aged 18-25 years with alcohol drinking. Participants will be randomized into a standard treatment (ST), II, or control arm. The ST group will receive a brief smoking cessation intervention based on the 5A (Ask, Assess, Advice, Assist, Arrange) and 5R (Relevance, Risks, Rewards, Roadblocks, Repetition) models. The II group will receive brief advice on alcohol use based on the FRAMES (Feedback, Responsibility, Advice, Menu, Empathy, Efficacy) model in addition to the brief smoking cessation intervention. Both the ST and II groups will receive booster interventions at 1-week, 1-month, 3-month, and 6-month follow-up. The control group will receive leaflets on smoking cessation and alcohol reduction. Self-reported quitters at 6-month follow-up will be invited for biochemical validation. The primary outcomes are feasibility measures. The secondary outcomes are effect size of II on self-reported and biochemically validated quit rates at 6 months relative to control and ST. Outcomes will be assessed at baseline and at 1-week, 1-month, 3-month, and 6-month follow-ups. ANALYSIS: Descriptive statistics will be used to calculate the feasibility measures. The three arms will be compared using analysis of variance for continuous variables and chi-square test for categorical variables. Effect sizes of II for self-reported and biochemically validated quit rates at 6 months will be determined using the generalized estimating equation model.

Factors associated with hand washing effectiveness: an institution-based observational study.

BACKGROUND: Few studies have investigated how the effectiveness of hand washing in removing hand contaminants is influenced by the performance and duration of each step involved. We conducted an observational study by recruiting participants from a university campus, with the aim to comprehensively evaluate how performance, duration and demographic factors influence hand washing effectiveness. METHODS: A total of 744 videos were collected from 664 participants in July-October 2022 and independently evaluated by two infection control experts through labelling videos for correct and incorrect performance of each step. The individual hand washing effectiveness was determined by quantifying the percentage of residual fluorescent gel on the dorsum and palm areas of each participant's hands. A logistic regression analysis was conducted to identify factors that were significantly associated with better hand washing effectiveness. An exposure-response relationship was constructed to identify optimal durations for each step. Approximately 2300 hand images were processed using advanced normalization algorithms and overlaid to visualize the areas with more fluorescence residuals after hand washing. RESULTS: Step 3 (rub between fingers) was the most frequently omitted step and step 4 (rub the dorsum of fingers) was the most frequently incorrectly performed step. After adjustment for covariates, sex, performance of step 4 and step 7 (rub wrists), rubbing hands during rinsing, and rinsing time were significantly associated with hand washing effectiveness. The optimal overall hand washing time was 31 s from step 1 to step 7, and 28 s from step 1 to step 6, with each step ideally lasting 4-5 s, except step 3. The palms of both hands had less fluorescence residuals than the dorsums. The areas where residuals most likely appeared were wrists, followed by finger tips, finger webs and thumbs. CONCLUSIONS: Performance and duration of some hand washing steps, sex and rinsing time were associated with hand washing effectiveness. The optimal duration might be applied to all seven steps to achieve the best decontamination results. Further studies are needed to refine hand hygiene standards and enhance compliance.

Factors associated with severe depressive symptoms among Chinese secondary school students in Hong Kong: a large cross-sectional survey.

Background: Many adolescents were reported to have severe depressive symptoms, and a careful assessment of its correlates is essential for prevention and intervention programs. This study aimed to gain insight into the prevalence of severe depressive symptoms and its association with factors at four levels (individual, relationship, school and society) in a large sample of Hong Kong Chinese secondary school students. Methods: Secondary school students from Secondary 1 through 7 were selected as participants using a cluster random sampling method. A questionnaire including inventories measuring 24 factors at the four levels (six individual factors, 11 relationship factors, three school factors, and four society factors) was completed by 8,963 participants (56.3% female) with a mean age of 15.1 (SD = 1.8) years. Students with a score of ≥15 on the Patient Health Questionnaire were defined as having severe depressive symptoms. The association between severe depressive symptoms and correlates were examined by t-test and χ2 test. Logistic regression models using a hierarchical approach then examined the individual contribution of these 24 factors to severe depressive symptoms with the control of other factors in the model. Results: 7.4% of the students have severe depressive symptoms. Twenty-two of the 24 factors were significantly associated with severe depressive symptoms in bivariate analyses. In the logistic regression, 11 factors (three individual factors: age, self-esteem and self-mastery; six relationship factors: tobacco use, alcohol drinking, drug use, paternal psychological control, dinner with parents, and perceived social support from friends; one school factor: felt pressure from homework; and one society factor: number of sibling) were statistically significant. Felt pressure from homework, alcohol drinking, and perceived social support from friends were the strongest correlates of severe depressive symptoms. Conclusion: The prevalence of self-reported severe depressive symptoms in Hong Kong Chinese secondary school students was high, and the identification of multiple associated factors at the four levels simultaneously provides a knowledge basis for the development of a comprehensive, multivariate model of factors influencing severe depressive symptoms in Chinese secondary school students. The factors identified in the present study may be helpful when designing and implementing preventive intervention programs.

Traditional Chinese medicine-based integrated health interventions for depression: A systematic review and meta-analysis.

BACKGROUND: Some traditional Chinese medicine (TCM)-based integrated health interventions have been used for depression, but pooled efficacy remains unknown. AIMS AND OBJECTIVES: This study aimed to systematically evaluate the efficacy of TCM-based integrated health interventions for relieving depression. DESIGN: Systematic review and meta-analysis. METHODS: A comprehensive literature search was conducted on 17 databases from inception up to June 2022. Randomised controlled trials (RCTs) that examined an integrated health intervention based on TCM theory for depression were included. The risk of bias was assessed using the second version of the Cochrane risk-of-bias tool for randomised trials, and the quality of evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluation system. RESULTS: Eighteen RCTs with a total of 1448 depressed participants were included. Health care providers, mainly nurses (14 studies), implemented TCM-based integrated health interventions. The pooled results showed that TCM-based integrated health interventions had larger effects on reducing depressive symptoms (15 studies; standardised mean difference = -2.05; 95% CI: -2.74, -1.37; p < .00001) compared with usual care at posttreatment but showed no significant difference contrasted to cognitive behavioural therapy (two studies, p = .31). However, the overall evidence was low. CONCLUSIONS: The meta-analysis results indicated that TCM-based integrated health interventions were effective in reducing depression. However, the results should be interpreted with caution because of the low quality of the included studies. Future RCTs with rigorous designs should be conducted to provide robust evidence of the efficacy of TCM-based integrated health interventions in treating depression. RELEVANCE TO CLINICAL PRACTICE: TCM-based integrated health interventions might be a potentially effective alternative for depression. Nurses could play an important role in designing and providing TCM-based integrated nursing interventions for patients with depression. NO PATIENT OR PUBLIC CONTRIBUTION: This is a systematic review and meta-analysis based on data from previous studies.

Magnitude and determinants of alcohol use disorder among adult population in East Asian countries: A systematic review and meta-analysis.

Introduction: Alcohol use disorder is a medical condition characterized by an impaired ability to control or stop alcohol use despite adverse health outcomes. Despite several studies that have analyzed the prevalence and determinants, their results have been equivocal, and the reasons for the differences in prevalence rates and determinants of AUD across nationalities are unknown. Hence, this study estimated the pooled prevalence of alcohol use disorder and its determinant among adults in East Asian countries. Methods: Articles were searched from PubMed, Web of Science, EMBASE, PsycINFO, and Scopus. All observational study designs that fulfilled the predefined criteria were included in the study. The findings were reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). The quality and heterogeneity of articles were assessed using the new castle-Ottawa scale (NOS) and I2, respectively. Additionally, publication bias was checked through funnel plot and Egger's regression test. Results: A total of 14 articles with 93, 161 study participants were considered in the study. Of which 9 studies were included in the meta-analysis of the 1-year prevalence of alcohol use disorder, 6 in the lifetime, 9 in alcohol abuse, and 8 in alcohol dependency. Consequently, the overall pooled prevalence of one-year alcohol use disorder was 8.88% (95% CI: 6.32, 11.44), lifetime 13.41% (95%CI: 8.48, 18.34), alcohol abuse 5.4% (95% CI: 2.66, 8.13), and alcohol dependency 4.47% (95% CI: 2.66, 6.27). In the subgroup analysis by country, the highest 1-year and lifetime pooled prevalence of alcohol use disorder was observed in Korea at 9.78% (95% CI:4.40, 15.15) and 16.73% (95% CI: 15.31, 18.16), respectively. Besides, smoking (OR: 3.99; 95% CI: 1.65, 6.33) and male gender (OR: 5.9; 95% CI: 3.3, 8.51) were significant determinants of alcohol use disorder. Conclusions: The magnitude of alcohol use disorder was high among adults in East Asian countries. Smoking and male gender were the key determinants of alcohol use disorders.

Experiences of seeking and accessing medical care among persons with major depression: A qualitative descriptive study of persons with depression in China.

Introduction: A large number of people in China are affected by depression, yet tend to delay seeking treatment. This study aims to explore persons living with depression and their journey of diagnoses and seeking professional medical help in China. Methods: Semi-structured interviews were conducted with 20 persons who visiting physicians to be diagnosed and receive professional help from a large mental health center in Guangzhou, Guangdong province, China. Individual interviews were conducted and data were analyzed using content analysis. Results: Three themes were identified from the findings: (1) "noticed something was wrong"; (2) negotiated decisions with their own narratives and the personal suggestions of others; and (3) gave new meaning to their experiences of depression, whereby they sought medical treatment. Discussion: The findings of the study indicated that the impact of progressive depressive symptoms on the participants' daily lives was a strong motivation for them to seek professional help. The obligation to care for and support their family prevented them from initially disclosing their depressive symptoms to family members, but eventually prompted them to seek professional help and persist in follow-up treatment. Some participants experienced unexpected benefits (e.g., relief at no longer feeling "alone") during their first visit to the hospital for depression or when they were diagnosed with depression. The results suggest a need to continue to actively screen for depression and provide more public education to prevent negative assumptions and reduce public and personal stigmatization of those with mental health problems.

Development of a Community-Based Network to Promote Anti-Drug Messaging and Identify Hidden Drug Abusers in Hong Kong.

Developing a community-based network by training peers as anti-drug ambassadors (ADAs) is a feasible strategy to identify hidden drug abusers. The Ask, Warn, Advise, Refer and Do-it-again (AWARD) model of smoking cessation is useful for enhancing people's confidence in making referrals to anti-drug services. This study evaluated the effectiveness of such a network by examining the change in knowledge, attitudes and practices (KAP) of 198 ADAs aged 13-18 before and after six months of our training. A one-group pre-test and repeated post-test design was used. One-way repeated-measures analysis of variance was applied to assess the changes in KAP, with p-values adjusted by Bonferroni correction. The results showed that the ADAs statistically significantly improved their KAP regarding drug abuse at the six-month follow-up compared to baseline. All ADAs who knew drug abusers (n = 3) had referred them to services based on the AWARD model. A total of 154 anti-drug abuse activities were conducted, reaching 4561 people. Based on the results, we concluded that the community-based network was effective in improving the KAP of ADAs regarding drug abuse, as well as referring hidden drug abusers. Future studies should consider implementing the network on a larger scale, thus maximizing its anti-drug capacity.

Use of a positive psychology intervention (PPI) to promote the psychological well-being of children living in poverty: study protocol for a feasibility randomised controlled trial.

INTRODUCTION: Poverty has a detrimental influence on psychological well-being of children. Existing evidence shows that positive psychology interventions are possible to mitigate such impact. Despite criticisms that positive psychology resembles a scientific Pollyannaism that promotes overly positivity, positive psychology is not the scientific Pollyannaism that denies the difficulties and emotions that people may experience. Whereas, positive psychology acknowledges the difficulties and emotions, alongside with building up human resilience, strength and growth to face adversity. This study examined the feasibility of implementing a positive psychology intervention among Hong Kong Chinese children living in poverty. METHODS: A feasibility randomised controlled trial will be conducted. A convenience sample of 120 children aged 13-17 years will be recruited from a community centre in Kwai Tsing district. Participants who are randomised into the experimental group will join a 1.5-hour workshop covering four positive psychology techniques: (1) gratitude visits/letters, (2) three good things, (3) you at your best and (4) using signature strengths. A booster intervention will be provided at 1 week. Control group participants will not receive any intervention. Assessments will be conducted at baseline and at 1-week, 1-month, 3-month and 6-month follow-ups. ANALYSIS: Descriptive statistics will be used to calculate the feasibility measures. Effect sizes on psychological outcomes (ie, self-esteem, depressive symptoms and quality of life) will be estimated by mixed between-within subjects analysis of variance using partial eta squared with poverty (yes, no) entering into the model as a factor. ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Hong Kong Polytechnic University Institutional Review Broad. We will obtain parental consent as our subjects are below 18 years old. Findings from this study will be disseminated via international publications and conferences. TRIAL REGISTRATION NUMBER: NCT04875507.

Exploring Contributing Factors of Solitary Drinking among Hong Kong Chinese Adolescents and Young Adults: A Descriptive Phenomenology.

Adolescents and young adults mostly drink alcohol because of social activities. However, some drink outside of normative social contexts, exhibiting a behaviour pattern known as solitary drinking. Increasing evidence indicates that solitary drinking is strongly associated with problematic drinking in adolescents and young adults. However, it remains unclear why individuals initiate and maintain this drinking habit. To address this gap in the existing literature, the current study explored the factors contributing to solitary drinking in this population. Descriptive phenomenology was used. A convenience sample of 44 solitary drinkers aged between 10 and 24 were invited to undergo individual semi-structured interviews. All interviews were audio-recorded and transcribed verbatim. The data were analysed by two researchers separately using Colaizzi's method. Using qualitative descriptions, the following factors were identified as explaining the initiation and continuation of solitary drinking among adolescents and young adults: (1) enhancement and coping drinking motives, (2) social discomfort, (3) reduced self-control, (4) automatic mental process, and (5) a desperate response to stressors. Since reduced self-control plays an important role in long-term addiction, future studies should be conducted to determine potential applications of mindfulness-based interventions to improve self-control, which may prevent the progression from solitary drinking to alcohol use disorder.

Exploring Factors Contributing to the Smoking Behaviour among Hong Kong Chinese Young Smokers during COVID-19 Pandemic: A Qualitative Study.

COVID-19 has significant impacts on young smokers in their smoking behaviors. This qualitative study summarises the lived experience of young smokers during COVID-19. Moreover, through their lived experience, we aim to understand how the COVID-19 pandemic influence tobacco use behaviours in this population. A purposive sampling of 48 smokers aged between 17-25 years old is individually interviewed for 30 to 45 min. All interviews are transcribed in verbatim and analysed by two researchers separately using Colaizzi's method of descriptive phenomenology. The results reveal the following six important themes, which could explain the mixed pattern of smoking behaviour changes in young smokers: (1) perceptions of COVID-19 and its association with smoking, (2) more time at home, (3) taking masks off to smoke, (4) the effects of COVID-19 on smokers' financial status and academic performance, (5) reduced social gatherings, and (6) restricted access to tobacco products. To conclude, this pandemic and the anti-pandemic measures, i.e., mask mandates, stay-at-home and work-from-home orders, and class suspension, result in both new obstacles and new advantages for smoking cessation among young people. More studies should be performed to monitor any transition of tobacco products and the trajectory of use in this population during this pandemic, thus informing public health policy making.

Acceptance and Commitment Therapy versus Social Support for Smoking Cessation for People with Schizophrenia: A Randomised Controlled Trial.

Smoking is prevalent among people with schizophrenia. It has been found that Acceptance and commitment therapy (ACT) is effective for treating psychotic symptoms and addictive behaviours, but the therapy has not been modified to help individuals with schizophrenia to quit smoking. A randomised controlled trial was conducted with the objective of comparing a 10-week, individual, face-to-face ACT programme (n = 65) to a social support programme on smoking cessation, experiential avoidance, and emotion-regulation strategies among people with schizophrenia who smoke (n = 65). The primary outcome was self-reported smoking abstinence for 7 days at 6 months after the start of the intervention. Secondary outcomes were self-reported and biochemically validated quit rates post-intervention. The Avoidance and Inflexibility Scale (AIS), Acceptance and Action Questionnaire II (AAQII), and Emotion Regulation Questionnaire (ERQ) were employed. The self-reported quit rates in the ACT group were higher than in the social support group, although no significant differences were found (6 months: 12.3% vs. 7.7%, p = 0.56, 12 months: 10.8% vs. 7.7%, p = 0.76). We found significantly greater improvements in smoking-specific and ACT-specific experiential avoidance and less reliance on emotion regulation strategies in the ACT group at some time points. Overall, ACT is better than social support at enhancing experiential avoidance and reducing reliance on emotion regulation strategies in adults with schizophrenia who smoke. However, ACT did not produce a much better result than social support in helping them to completely quit smoking.

Development and validation of a nomogram to predict the risk of breast cancer-related lymphedema among Chinese breast cancer survivors.

PURPOSE: Breast cancer-related lymphedema (BCRL) is a major long-term complication for post-surgery breast cancer survivors. Although several risk factors have been identified, lifestyle characteristics have been neglected in previous studies. The aim of this study was to develop and validate a nomogram for estimating this population's risk of developing lymphedema, taking into consideration their demographic, clinical, and personal lifestyle behaviors. METHODS: In a cross-sectional study, we collected data from 775 post-operative breast cancer survivors who had attended a follow-up session in the recent 10 years (primary cohort). Lymphedema was assessed using the Norman telephone questionnaire, self-reported by patients. Multiple logistic regression was used to identify risk factors for lymphedema, including demographic, clinical, and lifestyle-related factors. A nomogram was constructed based on those factors and was validated using a separate group of 314 breast cancer patients (validation cohort). RESULTS: The factors independently associated with lymphedema were higher body mass index (BMI), modified radical mastectomy (MRM), postsurgical infection, chemotherapy, radiotherapy, exercise of the affected arm, and the active participation in physical activity (P<0.05). The area under the curve (AUC) values of the primary and the validation cohorts were 0.721 (95% confidence interval: 0.685-0.756) and 0.702 (95% confidence interval: 0.646-0.759), respectively. CONCLUSIONS: BCRL risk factors include MRM, radiotherapy, chemotherapy, and higher BMI, while the active physical activity behavior of patients appears to be a factor against lymphedema. The nomogram incorporating the patients' clinical and lifestyle factors might be useful for predicting lymphedema in breast cancer survivors.

Validation of Self-Reported Smartphone Usage Against Objectively-Measured Smartphone Usage in Hong Kong Chinese Adolescents and Young Adults.

OBJECTIVE: This study evaluated the validity of self-reported smartphone usage data against objectively-measured smartphone usage data by directly tracking the activities in the participants' smartphone among Chinese adolescents and young adults in Hong Kong. METHODS: A total of 187 participants were recruited (mean age 19.4, 71.7% female) between 2017 and 2018. A smartphone usage tracking app was installed on all participants' smartphone for 7 consecutive days. After the 7-day monitoring period, they completed a selfadministered questionnaire on smartphone usage habits. RESULTS: Although the correlation between self-reported and objectively-measured total smartphone usage time was insignificant (ρ=-0.10, p=0.18), in three out of the four usage domains were positively and significantly correlated, namely social network (ρ=0.21, p=0.005), instant messaging (ρ=0.27, p<0.001), and games (ρ=0.64, p<0.001). Participants' self-report of the total time spent on smartphones exceeded the objective data by around 760 min per week (self-reported 1,930.3 min/wk vs. objectively-measured 1,170.7 min/wk, p<0.001). Most of the over-reporting was contributed by the web browsing domain (self-reported 447.8 min/wk vs. objectively-measured 33.3 min/wk, p<0.001). CONCLUSION: Our results showed large discrepancies between self-reported smartphone and objectively-measured smartphone usage except for self-reported usage on game apps.

Prevalence and predictors of breast cancer-related arm lymphedema over a 10-year period in postoperative breast cancer patients: A cross-sectional study.

PURPOSE: Breast cancer (BC) survivors have a lifelong risk of developing lymphedema. This study investigated the prevalence of BC-related arm lymphedema among Chinese BC survivors diagnosed in the last 10 years and examined the demographic and clinical variables as well as lifestyle factors associated with lymphedema status. METHODS: In this cross-sectional study, women with BC (N = 866) who had been diagnosed and followed up in the previous 10 years were recruited from the outpatient clinic of 4 general hospitals and one cancer association in China between August 2018 and October 2019. Lymphedema status was determined using the Norman telephone questionnaire as the patient-reported occurrence of hand/lower arm/upper arm swelling. Multiple logistic regression was used to identify risk factors for lymphedema. RESULTS: The median time from BC diagnosis was 4.0 years (interquartile range, 2.0-5.0 years). 81.4% of the patients had undergone mastectomy. The prevalence of arm lymphedema among BC survivors was 49.0%. Age ≥50 years, monthly income <3000 RMB, modified radical mastectomy, postsurgical wound infection, chemotherapy, and radiotherapy were associated with an increased risk of BC-related arm lymphedema, whereas exercise of the affected arm, engagement in active physical activity, and timely reporting of symptoms of infection to a physician decreased the risk (P < 0.05). CONCLUSIONS: Arm lymphedema is a common complication for postoperative BC survivors within 10 years. It is essential to identify patients at risk of lymphedema based on demographic, clinical, and lifestyle factors and implement interventions targeting modifiable lifestyle behaviors-eg, active physical activity during the postoperative period.
