Differences of biopsychosocial distress and requests for psychological assistance between Asian American and non-Hispanic White oncology patients.

OBJECTIVE: The purpose of this study was to compare Asian American (AA) to non-Hispanic White (NHW) cancer patients regarding biopsychosocial distress and requests for psychological assistance. METHODS: This retrospective study included 5627 eligible patients, newly diagnosed with cancer, who completed the 30-item SupportScreen® survey of biopsychosocial distress. The top 10 sources of high distress were assessed. Distress domains (Emotional, Physical/Functional, and Practical) were examined by race/ethnicity. Requests for psychological assistance were also explored by ethnic groups. RESULTS: Overall, the top 10 sources of high distress were similar between groups and approximately half consisted of concerns regarding physical symptoms. All patients preferred "talking" as their method of receiving assistance for these items. Ratings of emotional, practical, and physical/functional distress were similar between AA and NHW patients. However, AAs (vs. NHWs) requested more assistance regarding physical/functional and practical distress. No difference was observed between these two groups regarding requests for emotional support. CONCLUSIONS: Overall, our study suggests that healthcare providers should be aware of the physical and practical needs of AA cancer patients and provide culturally sensitive care that addresses these needs.

Efficacy of a Self-Directed Video-Based Caregiver-Implemented Language Programme.

INTRODUCTION: Caregiver-implemented language programmes are effective for alleviating early language difficulties. This study examined the efficacy of a self-directed video-based caregiver-implement language programme in Chinese families. METHOD: This study consisted of two stages. In stage 1, 31 caregiver-child dyads (typically developing children) completed the training programme (group 1) in the form of six video-based training modules. In stage 2, 28 caregiver-child dyads (children with language difficulties) receiving active speech therapy were randomly assigned to the training (group 2) and control arms (group 3). Group 2 received the same training as group 1 in addition to their regular therapy while group 3 was kept as status quo. Caregivers completed a quiz on their knowledge of language facilitation techniques (LFTs) and submitted caregiver-child interaction videos at the start and end of the training. Outcome measures included programme completion rate, quiz scores, and use of LFTs and children's communication skills in the videos. A pre-post design and a between-group design were adopted in the stage 1 and 2 studies, respectively. RESULTS: A completion rate of about 60% in both stages was noted. Significantly higher post-training knowledge scores were found in groups 1 and 2. General but nonsignificant growth in use of parallel talk and gesture, and significant gains in children's vocalization in the training arm were observed. CONCLUSION: The self-directed video-based training programme would be useful in imparting information to caregivers. However, the modest improvements in the use of LFTs suggested direct coaching appeared to still play a significant role in enhancing the actual implementation of LFTs. Further investigation on a larger scale is required to evaluate the effectiveness of the training programme for promoting the wider use of this mode as a preventive measure.

Electric field and strain engineering tuning Rashba spin splitting in quasi-one-dimensional organic-inorganic hybrid perovskites (MV)AI3Cl2 (MV = methylviologen, A = Bi, Sb).

We systematically study the Rashba spin texture of lead-free quasi-one-dimensional organic-inorganic hybrid perovskites (OIHP), (MV)AI3Cl2 (MV = methylviologen, A = Bi, Sb) with first-principles calculations. The kx-ky plane Rashba spin splitting was found to depend on the composition of Bi (Sb) and I atoms at band edges. Importantly, increasing ferroelectric polarization and the stretch along the z-direction can effectively enhance the amplitude of the Rashba spin splitting. This work provides an avenue for electric field and strain-controlled spin splitting and highlights the potential of quasi-one-dimensional OIHP for further applications in spin field effect transistors and photovoltaic cells.

A limited capacity for microglial repopulation in the adult brain.

Microglia are the resident immune cell of the central nervous system (CNS), and serve to protect and maintain the local brain environment. Microglia are critically dependent on signaling through the colony-stimulating factor 1 receptor (CSF1R); administration of CSF1R inhibitors that cross the blood brain barrier (BBB) lead to the elimination of up to 99% of microglia, depending on CNS exposure and treatment duration. Once microglia are depleted, withdrawal of inhibitor stimulates repopulation of the entire CNS with new cells, conceivably enabling a therapeutic strategy for beneficial renewal of the entire microglial tissue. We have explored the kinetics and limits of this repopulation event and show that the rate of microglial repopulation is proportional to the extent of microglial depletion - greater depletion of microglia results in more rapid repopulation. Using a CSF1R inhibitor formulation that eliminates approximately 99% of microglia within 7 days, we subjected mice to multiple rounds of elimination (7 days' treatment) and repopulation (7 days' recovery) and found that the brain only has the capacity for a single complete repopulation event; subsequent elimination and CSF1R inhibitor withdrawal fail to repopulate the brain. However, if the recovery time between, or after, cycles is extended sufficiently then the brain can ultimately repopulate. These kinetic studies define the opportunities and possible limits of the remarkable renewal capacities of microglia.

Synthesis, Structure, and Electrical Properties of the Single Crystal Ba8Cu16As30.

Single crystals of clathrate-I Ba8Cu16As30 have been synthesized and their structure and electronic properties determined using synchrotron-based X-ray diffraction and first-principles calculations. The structure is confirmed to be Pm3̅ n (No. 223), with lattice parameter a = 10.4563(3) Å, and defined by a tetrahedrally bonded network of As and Cu that forms two distinct coordination polyhedra, with Ba residing inside these polyhedra. All crystallographic positions are fully occupied with no vacancies or superstructure with the Cu atoms, while occupying all framework sites in the network, exhibiting a preference for the 6c site. Agreement between the experimental and theoretically predicted structures was achieved after accounting for spin-orbit coupling. Our calculated Fermi surface, electron localization, and charge transfer, as well as a comparison with the results for elemental As46, provide insight into the fundamental properties of this clathrate-I material.

Effect of clozapine and olanzapine on neutrophil kinetics: implications for drug-induced agranulocytosis.

Clozapine is effective in the treatment of schizophrenia; however, its use is limited by a relatively high incidence of idiosyncratic agranulocytosis. The mechanism of clozapine-induced idiosyncratic agranulocytosis is unknown. Although most patients treated with clozapine do not develop agranulocytosis, most do have an immune response with an increase in inflammatory cytokines such as IL-6 and a release of immature neutrophils with neutrophilia rather than agranulocytosis. We have previously shown that treatment of rabbits with clozapine also causes an early release of neutrophils. Clozapine is oxidized to a reactive nitrenium ion that covalently binds to neutrophils, and this reactive metabolite may be responsible for the observed effects. Olanzapine and clozapine have very similar structures, and olanzapine is also oxidized to a reactive nitrenium ion; however, if it ever causes agranulocytosis, the incidence is much lower than that of clozapine. One possible basis for the difference in incidence of agranulocytosis between clozapine and olanzapine is that the therapeutic dose of olanzapine is much lower than that of clozapine. In this study, we compared the effects of clozapine and olanzapine in Sprague-Dawley rats at an equimolar dose and found that only clozapine had a significant effect on neutrophil kinetics. This suggests that the immune response and effects on neutrophil kinetics induced by clozapine are related to its ability to cause agranulocytosis.

The psychophysiological effects of Tai-chi and exercise in residential schizophrenic patients: a 3-arm randomized controlled trial.

BACKGROUND: Patients with schizophrenia are characterized by high prevalence rates and chronicity that often leads to long-term institutionalization. Under the traditional medical model, treatment usually emphasizes the management of psychotic symptoms through medication, even though anti-psychotic drugs are associated with severe side effects, which can diminish patients' physical and psychological well-being. Tai-chi, a mind-body exercise rooted in Eastern health philosophy, emphasizes the motor coordination and relaxation. With these potential benefits, a randomized controlled trial (RCT) is planned to investigate the effects of Tai-chi intervention on the cognitive and motor deficits characteristic of patients with schizophrenia. METHODS/DESIGN: A 3-arm RCT with waitlist control design will be used in this study. One hundred and fifty three participants will be randomized into (i) Tai-chi, (ii) exercise or (iii) waitlist control groups. Participants in both the Tai-chi and exercise groups will receive 12-weeks of specific intervention, in addition to the standard medication and care received by the waitlist control group. The exercise group will serve as a comparison, to delineate any unique benefits of Tai-chi that are independent of moderate aerobic exercise. All three groups will undergo three assessment phases: (i) at baseline, (ii) at 12 weeks (post-intervention), and (iii) at 24 weeks (maintenance). All participants will be assessed in terms of symptom management, motor coordination, memory, daily living function, and stress levels based on self-perceived responses and a physiological marker. DISCUSSION: Based on a promising pilot study conducted prior to this RCT, subjects in the Tai-chi intervention group are expected to be protected against deterioration of motor coordination and interpersonal functioning. They are also expected to have better symptoms management and lower stress level than the other treatment groups. TRIAL REGISTRATION: The trail has been registered in the Clinical Trials Center of the University of Hong Kong (HKCTR-1453).

Effects of Online Health Promotion Program to Improve the Health and Wellbeing of Healthcare Students: A Feasibility Study.

BACKGROUND: Healthcare students' health and wellbeing have been seriously affected worldwide. Research studies highlighted the need to establish health promotion strategies to improve them. METHODS: A mixed method feasibility with a randomized controlled trial study followed by qualitative focus-group interviews to evaluate the effect of a 24 h online health promotion program improving healthcare students' health and wellbeing was performed in mid-2022. The study also illustrated the program's effect, contents, and activity arrangements. Healthcare students from two large tertiary institutions were randomly assigned to intervention and waitlist-control groups. Outcomes were measured by self-completed online questionnaires at three-time points (baseline, week four, and week eight), and in-depth focus-group interviews followed. RESULTS: Among 70 enrolled and 60 eligible students, 54 completed the study, with a 10% attrition rate. Results demonstrated a significant difference between groups at week eight. Within the intervention group, there were significant differences were found from baseline to week eight for depression (p = 0.001), anxiety (p = 0.004), and stress (p < 0.001). The program also improved certain domains of personal wellbeing and quality of life. Qualitative findings further illustrated the program contents and activities' feasibility, acceptability, and suitability. Most participants welcomed the online mode's flexibility and convenience. They enjoyed diversified and complementary content and activities. They had increased self-awareness of health and wellbeing. Besides, mental health knowledge enables them to 'self-care' and help those in need in the future. CONCLUSIONS: The results indicate the feasibility of performing full-scale research in the future and may provide more support for the students of higher education institutions.

Physical Activity, Sedentary Behavior, and Body Image among Young Adults in Hong Kong: A Cross-Sectional Study.

The COVID-19 pandemic has considerably impacted the health and lifestyle of various populations worldwide, leading to decreased physical activity, increased sedentary behavior, and increased health problems. This study aimed to investigate Hong Kong young adults' physical activity, related behaviors, and perceptions of body image during the pandemic. A cross-sectional online survey of young adults aged 18-29 was conducted from February to March 2021 using the well-validated Multidimensional Body Self-Relations Questionnaire (MBSRQ). Among 408 respondents, 52.5% had a normal weight in the BMI range, 45.1% engaged in ≥8 h of sedentary behavior daily, 77.2% engaged in no regular or inadequate physical activity (<2.5 h/week), and only 22.3% joined a fitness club. BMI, regular physical activity, and joining any fitness club/class were significantly associated with the most factors or additional subscales. A multiple linear regression model showed that the underweight respondents (reference group: normal) (ß = -0.26, 95% CI: -0.41 to -0.12) were less likely to have high scores of fitness orientation. The respondents who engaged in regular physical activity <2.5 h/week (ß = 0.42, 95% CI: 0.29 to 0.54), engaged in regular physical activity ≥2.5 h/week (ß = 0.99, 95% CI: 0.84 to 1.14) (reference group: no regular physical activity), and joined a fitness club/class (ß = 0.32, 95% CI: 0.18 to 0.45) were more likely to have a high score of fitness orientation. Local governments, non-governmental organizations, schools, and community centers should establish appropriate strategies and activities in order to sufficiently encourage and support young adults' physical health and well-being.

Self-perceived upper extremity motor function predicts health-related quality of life in chronic stroke survivors.

PURPOSE: To examine whether the Upper Extremity Functional Index (UEFI) score independently contributes to the Stroke Impact Scale (SIS) score and quantified its relative contribution to SIS scores in chronic stroke survivors. MATERIALS AND METHODS: A cross-sectional study in a university-based rehabilitation centre with people with chronic stroke (N = 95) aged ≥ 50 years. The outcome measures included paretic hand grip strength, Fugl-Meyer Upper Extremity Assessment (FMA-UE), Wolf Motor Function Test (WMFT), UEFI, and SIS. RESULTS: Correlation analysis revealed that paretic hand grip strength, FMA-UE, UEFI, and WMFT scores exhibited a significant moderate positive correlation with SIS scores (r = 0.544-0.687, p < 0.001). The results of a regression model indicated that after adjustment for demographic factors and stroke-related impairments, the UEFI scores remained independently associated with SIS scores, accounting for 18.8% of the variance. The entire model explained 60.3% of the variance in SIS scores. CONCLUSIONS: Self-perceived UE motor function is a crucial component to be included in rehabilitation programmes aimed at enhancing quality of life and participation among chronic stroke survivors.

Observation-based outcome measures, e.g., Fugl­Meyer Assessment for Upper Extremity (FMA-UE), Wolf Motor Function Test (WMFT) could not predict the health-related quality of life (Stroke Impact scale (SIS)) in chronic stroke survivors in our study, which was contradictory with current studies.A self-perceived outcome measure to evaluate upper extremity function (Upper Extremity Functional Index (UEFI)) could independently predict the health-related quality of life (SIS), accounting for 18.8% of the variance.Our study demonstrated that self-perceived UE motor function would be an important component to optimize the rehabilitation programmes aimed at enhancing quality of life and social participation among chronic stroke survivors.

Effects of mirror therapy with electrical stimulation for upper limb recovery in people with stroke: a systematic review and meta-analysis.

PURPOSE: To provide updated evidence about the effects of MT with ES for recovering upper extremities motor function in people with stroke. METHODS: Systematic review and meta-analysis were completed. Methodological quality was assessed using the version 2 of the Cochrane risk-of-bias tool. The GRADE approach was employed to assess the certainty of evidence. RESULTS: A total of 16 trials with 773 participants were included in this review. The results demonstrated that MT with ES was more effective than sham (standardized mean difference [SMD], 1.89 [1.52-2.26]) and ES alone (SMD, 0.42 [0.11-0.73]) with low quality of evidence, or MT alone (SMD, 0.47[0.04-0.89]) with low quality of evidence for improving upper extremity motor control assessed using Fugl-Meyer Assessment. MT with ES had significant improvement of (MD, 6.47 [1.92-11.01]) the upper extremity gross gripping function assessed using the Action Research Arm Test compared with MT alone with low quality of evidence. MT combined with ES was more effective than sham group (SMD, 1.17 [0.42-1.93) for improving the ability to perform activities of daily living with low quality of evidence assessed using Motor Activity Log. CONCLUSION: MT with ES may be effective in improving upper limb motor recovery in people with stroke.

Combining Mirror Therapy (MT) and Electrical Stimulation (ES) modality could improve upper limb motor control, gross gripping function, and performance in ADLs based on ICF for people with stroke.Those individuals with subacute stroke are recommended as the optimal target group for the combined MT and ES.

Effect of aminoglutethimide on neutrophils in rats: implications for idiosyncratic drug-induced blood dyscrasias.

Aminoglutethimide (AMG) is an aromatic amine aromatase inhibitor associated with a high incidence of idiosyncratic blood dyscrasias, especially agranulocytosis. Animal models of idiosyncratic drug reactions (IDRs) represent essential tools to study these reactions; however, there is currently no valid model of idiosyncratic drug-induced agranulocytosis. Although AMG does not cause agranulocytosis in most animals or humans, drugs associated with serious IDRs generally cause a higher incidence of mild reactions that resolve despite continued treatment. Therefore, the effects of AMG on neutrophils and bone marrow in rats were studied to understand the mechanisms of more serious IDRs. An increase in peripheral blood neutrophils occurred as early as 24 h after AMG treatment with minimal changes to the total leukocyte count. Further investigation using 5-bromo-2'-deoxyuridine (BrdU) found an increased release of neutrophils from the bone marrow. Histologically, this corresponded to an increase in myeloid cells in the bone marrow, which was confirmed by differential staining with CD45 and CD71. AMG treatment stimulated an increase in colony forming unit granulocyte-macrophage and colony forming unit granulocyte ex vivo. There was also a marked increase in the number of activated neutrophils in the circulation expressing the extravasation marker CD62L. These findings indicate that AMG affects neutrophil production, release, and function. Similar effects on neutrophil kinetics in clozapine-treated rats have previously been found, and transient neutrophilia has been observed in patients taking other drugs associated with idiosyncratic agranulocytosis; therefore, the changes observed with AMG may be biomarkers to predict the risk that a drug will cause agranulocytosis.

Measurement, standards, and data needs for CO2 capture materials: a critical review.

The commercial deployment of cost-effective carbon capture technology is hindered partially by the lack of a proper suite of materials-related measurements, standards, and data, which would provide critical information for the systematic design, evaluation, and performance of CO2 separation materials. Based on a literature search and conversations with the carbon capture community, we review the current status of measurements, standards, and data for the three major carbon capture materials in use today: solvents, solid sorbents, and membranes. We highlight current measurement, standards and data activities aimed to advance the development and use of carbon capture materials and major research needs that are critical to meet if innovation in carbon capture materials is to be achieved. The review reveals that although adsorbents are considered to have great potential to reduce carbon capture cost, there is no consensus on the experimental parameters to be used for evaluating sorbent properties. Another important finding is the lack of in situ experimental tools for the structural characterization of solid porous materials during CO2 adsorption, and computational methods that would enable a materials-by-design approach for their development.

Structure, electrical and thermal properties of single-crystal BaCuGdTe3.

Single crystals of the quaternary chalcogenide BaCuGdTe3 were obtained by direct reaction of elements allowing for a complete investigation of the intrinsic electrical and thermal properties of this previously uninvestigated material. The structure was investigated by high-resolution single-crystal synchrotron X-ray diffraction, revealing an orthorhombic crystal structure with the space group Cmcm. Although recently identified as a semiconductor suitable for thermoelectric applications from theoretical analyses, our electrical resistivity and Seebeck coefficient measurements show metallic conduction, the latter revealing strong phonon-drag. Temperature dependent hole mobility reveals dominant acoustic phonon scattering. Heat capacity data reveal a Debye temperature of 183 K and a very high density of states at the Fermi level, the latter confirming the metallic nature of this composition. Thermal conductivity is relatively high with Umklapp processes dominating thermal transport above the Debye temperature. The findings in this work lay the foundation for a more detailed understanding of the physical properties of this and similar multinary chalcogenide materials, and is part of the continuing effort in investigating quaternary chalcogenide materials and their suitability for use in technological applications.

Effects of a culturally adapted counselling service for low-income ethnic minorities experiencing mental distress: a pragmatic randomised clinical trial.

BACKGROUND: Culturally competent early mental health interventions for ethnic minorities (EMs) with no formal diagnoses are needed. OBJECTIVES: To determine whether 8-12 weeks culturally adapted counselling (CAC) is better than waiting (waitlist (WL) group) to reduce depressive and anxiety symptoms and stress levels among EMs with elevated mental distress. METHODS: Hong Kong EMs with mild and above-mild mental distress were randomly assigned to CAC or WL in this pragmatic, randomised, WL-controlled trial. The CAC group received the intervention after randomisation and the WL group received the intervention after 8-12 weeks (T1). The prespecified primary outcomes were depressive and anxiety symptoms and stress levels measured by the Depression, Anxiety and Stress subscales of the Depression, Anxiety and Stress Scale (DASS-D, DASS-A and DASS-S, respectively) at postintervention (T1, 8-12 weeks). FINDINGS: A total of 120 participants were randomly assigned to either CAC (n=60) or WL (n=60), of whom 110 provided primary outcome data. At T1, CAC led to significantly lower depressive and anxiety symptom severity and stress levels compared with waiting, with unstandardised regression coefficients of -8.91 DASS-D points (95% CI -12.57 to -5.25; d=-0.90),-6.33 DASS-A points (95% CI -9.81 to -2.86; d=-0.68) and -8.60 DASS-S points (95% CI -12.14 to -5.06; d=-0.90). CONCLUSIONS: CAC clinically outperformed WL for mild and above-mild levels of mental distress in EMs. CLINICAL IMPLICATIONS: Making CAC routinely available for EMs in community settings can reduce healthcare burden. TRIAL REGISTRATION NUMBER: NCT04811170.

The oncogenic potential of Rab-like protein 1A (RBEL1A) GTPase: The first review of RBEL1A research with future research directions and challenges.

Research on Rab-like protein 1A (RBEL1A) in the past two decades highlighted the oncogenic properties of this gene. Despite the emerging evidence, its importance in cancer biology was underrated. This is the first RBEL1A critical review covering its discovery, biochemistry, physiological functions, and clinical insights. RBEL1A expression at the appropriate levels appears essential in normal cells and tissues to maintain chromosomal stability; however, its overexpression is linked to tumorigenesis. Furthermore, the upstream and downstream targets of the RBEL1A signaling pathways will be discussed. Mechanistically, RBEL1A promotes cell proliferation signals by enhancing the Erk1/2, Akt, c-Myc, and CDK pathways while blunting the apoptotic signals via inhibitions on p53, Rb, and caspase pathways. More importantly, this review covers the clinical relevance of RBEL1A in the cancer field, such as drug resistance and poor overall survival rate. Also, this review points out the bottle-necks of the RBEL1A research and its future research directions. It is becoming clear that RBEL1A could potentially serve as a valuable target of anticancer therapy. Genetic and pharmacological researches are expected to facilitate the identification and development of RBEL1A inhibitors as cancer therapeutics in the future, which could undoubtedly improve the management of human malignancy.

Time-dependent CO2 sorption hysteresis in a one-dimensional microporous octahedral molecular sieve.

The development of sorbents for next-generation CO(2) mitigation technologies will require better understanding of CO(2)/sorbent interactions. Among the sorbents under consideration are shape-selective microporous molecular sieves with hierarchical pore morphologies of reduced dimensionality. We have characterized the non-equilibrium CO(2) sorption of OMS-2, a well-known one-dimensional microporous octahedral molecular sieve with manganese oxide framework. Remarkably, we find that the degree of CO(2) sorption hysteresis increases when the gas/sorbent system is allowed to equilibrate for longer times at each pressure step. Density functional theory calculations indicate a "gate-keeping" role of the cation in the tunnel, only allowing CO(2) molecules to enter fully into the tunnel via a highly unstable transient state when CO(2) loadings exceed 0.75 mmol/g. The energy barrier associated with the gate-keeping effect suggests an adsorption mechanism in which kinetic trapping of CO(2) is responsible for the observed hysteretic behavior.

The Impacts of the COVID-19 Pandemic on Hong Kong Nursing Students' Mental Health and Quality of Life.

Evidence shows that university students, especially healthcare students, experienced considerable health impacts during COVID-19. This study examined Hong Kong general nursing students' mental health and quality of life during the COVID-19 pandemic. An online questionnaire composed of personal demographics, the Fear of COVID-19 scale (FCV-19S), the Depression Anxiety Stress Scale short version (DASS21), and the World Health Organization Quality of Life-BREF (WHOQOL-BREF) was used for data collection in early 2021. Among 380 respondents, 170 (45%) did not attend clinical practicum during the pandemic. Students who did not participate in clinical training scored lower in FCV-19S but higher in WHOQOL-BREF than those who participated (p = 0.001 or p < 0.001). FCV-19S and WHOQOL-BREF were negatively correlated (r = -0.623 to -0.446, p < 0.001). Slight negative correlations were found between the FCV-19S and DASS-21 scores. Although there were no significant differences in DASS21 (p = 0.294-0.931) between these two student groups, there was a considerably high prevalence rate of depression (57.1%), anxiety (47.6%), and stress (39.5%). Hong Kong nursing students, especially those who attended clinical practicum during the pandemic, experienced substantial emotional and quality of life implications. Local universities are recommended to organize appropriate interventions to prepare and support nursing students' wellbeing and health in coping with future disasters.

A Cluster Randomized Controlled Trial Feasibility Study of a WhatsApp-Delivered Intervention to Promote Healthy Eating Habits in Male Firefighters.

This cluster randomized controlled trial (CRCT)-designed study aimed to explore the feasibility of a promotion pamphlet and/or WhatsApp as a suitable mode of delivery to promote healthy eating habits with fruit and vegetables (F&V) among firefighters. Convenience and snowball sampling methods were used. Forty-five firefighters from 23 fire stations were recruited and they all received the printed pamphlet, while the intervention group participants (n = 20) received additional teaching material through WhatsApp every two weeks for eight weeks. Feasibility outcomes included retention, practicality, and implementation. The participants reported high levels of satisfaction with the intervention. There were significant improvements in the mean numbers of days consuming F&V (p = 0.002; p = 0.031) in the intervention group, and for fruit consumption (p = 0.033) in the control group between the baseline (T0) and 3 months after completion of intervention (T1). High levels of participants' satisfaction with the intervention revealed that a full-scale CRCT of the WhatsApp-delivered intervention promoting healthy eating could be feasible, especially as a means of increasing the numbers of days they consumed F&V and the numbers of servings of these consumed per day.
