RESUMO

BACKGROUND: Major Depressive Disorder (MDD) is a leading cause of disability worldwide. Approximately one-third of patients with MDD do not respond to treatment, and often exhibit elevated inflammation biomarkers, which are associated with worse prognosis. Previous research has linked healthier dietary patterns, such as the Mediterranean Diet (MedDiet), with a lower risk of MDD and symptoms of depression, potentially due to their anti-inflammatory properties. The aim of this study is to evaluate the effectiveness of a nutritional counselling intervention promoting MedDiet to alleviate symptoms of depression in adults recently diagnosed with MDD and presenting with elevated inflammation biomarkers. METHODS: This study is a randomized controlled trial (RCT) that will recruit adults from outpatient clinics, between the ages of 18 and 70 years who have been diagnosed with MDD and are currently receiving treatment with the first prescribed antidepressant, and who exhibit elevated inflammation biomarkers (interleukin-6 and/or C-reactive protein). The control group will receive treatment-as-usual (TAU) only. The primary outcome of the study will be the change in symptoms of depression, as measured by the Beck Depression Inventory 2 (BDI-II), after 12 weeks of intervention. Data analysis will follow an intention-to-treat approach. Secondary outcomes will include changes in inflammation biomarkers, quality of life, adherence to the MedDiet, and cost-effectiveness of nutritional counselling. All outcomes will be assessed at baseline, after the 12-week intervention, and at 6- and 12-months post-baseline. DISCUSSION: This study will be the first RCT to evaluate the effect of a nutritional intervention with anti-inflammatory properties, as an adjuvant in the treatment of MDD, in individuals diagnosed with MDD and elevated inflammation biomarkers. The results of this study may contribute to the development of more effective and personalized interventions for MDD patients with elevated inflammation biomarkers.

RESUMO

BACKGROUND: Chronic benzodiazepine use is a challenge in primary care practice. Protocols to support safe discontinuation are still needed, especially in countries with high utilization rates. OBJECTIVES: To evaluate the feasibility, effectiveness, and safety of a benzodiazepine discontinuation protocol in primary care setting. METHODS: Nonrandomized, single-arm interventional study, at primary care units. Family physicians (FPs) recruited patients (18-85 years-old) with benzodiazepine dependence and chronic daily use ≥3 months. Patients with daily dosages ≥30 mg diazepam-equivalent, taking zolpidem, with a history of other substance abuse or major psychiatric disease were excluded. After the switch to diazepam, the dosage was gradually tapered according to a standardized protocol. Primary endpoint was the percentage of patients who stopped benzodiazepine at the intervention last visit. Dosage reduction, withdrawal symptoms, patients' and FPs' satisfaction with the protocol were evaluated. RESULTS: From 66 enrolled patients (74% female; 66.7% aged >64 years; median time of benzodiazepine use was 120 months), 2 withdrew due to medical reasons and 3 presented protocol deviations. Overall, 59.4% of participants successfully stopped benzodiazepine (60.7% when excluding protocol deviations). Men had higher probability of success (relative risk = 0.51, P = 0.001). A total of 31 patients reported at least 1 withdrawal symptom, most frequently insomnia and anxiety. Most of participating FP considered the clinical protocol useful and feasible in daily practice. Among patients completing the protocol, 77% were satisfied. For the patients who reduced dosage, 85% kept without benzodiazepines after 12 months. CONCLUSION: The discontinuation protocol with standardized dosage reduction was feasible at primary care and showed long-term effectiveness.

RESUMO

This study aimed to understand how beliefs and attitudes regarding COVID-19 are associated with self-perceived changes in food consumption during lockdown between March 19 and May 2, 2020. We conducted a cross-sectional study with a non-probabilistic weighted sample of the Portuguese population. Data were collected using an online survey and telephone interviews. The association between agreement with sentences about food and COVID-19 and perceived changes in food consumption were assessed by multinomial logistic regression models. Overall, 5858 citizens were included, with a mean age of 38.2 (17.3) years. Exclusive agreement with the belief "SARS-CoV-2 can be transmitted by food" (27.5%) was associated with decreased odds of perceived positive changes (e.g., increased consumption of fruit and vegetables). Agreement only with the attitudinal sentence "I started to consume foods that may protect against COVID-19" (11.9%) was associated with positive perceived consumption changes (e.g., increasing fruit and vegetables, and decreasing soft drinks and snacks). Cumulative agreement (with both sentences; 10.6%) was also associated with mostly positive food consumption changes. Specific beliefs and attitudes regarding COVID-19 and food are associated with self-perceived changes in food consumption. Longitudinal research is needed to understand how beliefs and/or attitudes about the role of food in infectious diseases act as determinants of eating behavior modification.

RESUMO

BACKGROUND: Unemployment can involve financial strain and major psychosocial challenges. Integration of the existing evidence is needed to better characterize the association between unemployment and mental health, independently of macroeconomic contexts. AIMS: Main objectives of this study: (a) review, integrate, and summarize evidence about the association between unemployment and anxiety disorders, mood disorders, and suicidal behaviour, and (b) identify variables affecting this association. METHOD: Systematic review of literature following PRISMA guidelines. PubMed, Web of Science, SciELO, RCAAP, and Cochrane Library databases were searched. Quantitative empirical studies on the association between unemployment and mental illness of community-based samples were included. The quality of the evidence provided in the studies was assessed following pre-defined methodological criteria. RESULTS: Overall, 294 articles were considered eligible. In total, 55.7% of the studies were conducted in Europe; 91.4% supported a positive association between increased unemployment rates and anxiety, mood disorders, or suicidal behavior. Men and young adults were most severely affected by unemployment. Education and social support were found to buffer the negative outcomes of job loss. CONCLUSIONS: Unemployment was inversely associated with mental health irrespectively of the economic context; unemployed individuals were more vulnerable to commit suicide and suffer from anxiety and mood disorders.

RESUMO

Front-of-pack nutrition labels (FOP-NL) are efficient tools for increasing consumers' awareness of the nutritional quality of food products, prompting healthier food choices. The main goal of this study was to evaluate the impact of four FOP-NL schemes - Traffic Light label (TL), Guideline Daily Amounts (%GDA), Nutri-Score (NS) and Health Star Rating (HSR) - on consumers' selection of food products according to perceived nutritional quality. A cross-sectional open-label crossover randomized controlled study was carried out among Portuguese consumers. A web-based questionnaire was used to assess participants' a) preferences regarding FOP-NLs and b) capacity to select healthy products in a food selection task using the information from FOP-NL schemes. When performing the selection task, participants had the option to indicate that they could not decide simply based on the presented FOP-NL (requiring more information). Overall, 357 adults participated in the study. Regarding consumers' preferences, TL received the most favorable responses, while NS received the fewest. All FOP-NLs performed better than the no-nutritional label control condition in the food selection task. The highest proportion of correct choices was obtained for TL (72.3%), followed by HSR (70.9%), %GDA (70.0%) and NS (62.2%), though no significant differences were found among FOP-NLs. Percentages of respondents indicating not being able to answer due to lack of information affected the proportion of correct choices, with 10.3% for TL, 12.9% for %GDA, 14.6% for HSR, and 25.8% for NS, indicating they were unable to choose without additional information. Although no particular FOP-NL system stood out as the most significantly effective, TL was the most preferred by Portuguese adults. Long-term real-world evidence is necessary to assess the impact of FOP-NL systems on individuals' food choices.

RESUMO

Game-based interventions (GBI) have been used to promote health-related outcomes, including cognitive functions. Criteria for game-elements (GE) selection are insufficiently characterized in terms of their adequacy to patients' clinical conditions or targeted cognitive outcomes. This study aimed to identify GE applied in GBI for cognitive assessment, training or rehabilitation. A systematic review of literature was conducted. Papers involving video games were included if: (1) presenting empirical and original data; (2) using video games for cognitive intervention; and (3) considering attention, working memory or inhibitory control as outcomes of interest. Ninety-one papers were included. A significant difference between the number of GE reported in the assessed papers and those composing video games was found (p < .001). The two most frequently used GE were: score system (79.2% of the interventions using video games; for assessment, 43.8%; for training, 93.5%; and for rehabilitation, 83.3%) and narrative context (79.2% of interventions; for assessment, 93.8%; for training, 73.9% and for rehabilitation, 66.7%). Usability assessment was significantly associated with six of the seven GE analyzed (p-values between p ≤ 0.001 and p. = 027). The use of GE that act as extrinsic motivation promotors (e.g., numeric feedback system) may jeopardize patients' long-term adherence to interventions, mainly if associated with progressive difficulty-increase of gaming experience. Lack of precise description of GE and absence of a theoretical framework supporting GE selection are important limitations of the available clinical literature.

RESUMO

BACKGROUND: In 2015, Portugal was the OECD country with the highest reported consumption of BZD. Physician's perceptions and attitudes regarding BZD are main determinants of related prescription habits. This study aimed to characterize beliefs and attitudes of Portuguese physicians regarding the prescription, management challenges, benefits, risks and withdrawal effects of BZD. METHODS: A cross-sectional, observational study with online data collection through anonymous self-administered questionnaire. Physicians registered with the Portuguese Medical Association were invited to participate through direct e-mail message. Physicians were asked to give their opinion (using a 5-points Likert scale) regarding the prescription of BZD, their benefits and risks in the management of insomnia and anxiety, the possible adverse effects of chronic use and alternative non-pharmacologic approaches. Descriptive statistics were used and groups were compared through logistic regression. RESULTS: A total of 329 physicians participated in the study (56% family physicians). Mean age was 44.10 ± 15.2 years, with 19.03 ± 14.9 years of clinical experience. Fifty eight percent of participants were female. Physicians reported BZD's negative impact on cognitive function (89%), association with road traffic accidents (88%) and falls (79%). Also, 58% shared the belief that chronic use is justified if the patient feels better and without adverse events. Although 68% reported to feel capable of helping patients to reduce or stop BZD, 55% recognized difficulties in motivating them. Compared to other medical specialists (altogether), family physicians were significantly more aware about the adverse effects of BZD and considered that chronic use may not be justified. Conversely, more family physicians expressed concerns about their skills to motivate patients engaging in withdrawal programs and to support them during the process. CONCLUSION: Our results show that physicians' awareness about risks of BZD chronic use is adequate though their attitudes and self-perceived skills towards promoting BZD withdrawal can be improved. Interventions in primary care are needed to capacitate physicians to better motivate patients for BZD withdrawal.

RESUMO

BACKGROUND: The existing knowledge on the interplay between reproductive and sexual health, migration and acculturation is recent and inconsistent, particularly on the sociocultural motives and constraints regarding fertility. Therefore, sexual and reproductive health (SRH) surveys are needed to provide accurate and comparable indicators to identify and address SRH inequalities, with specific focus on under researched aspects, such as the interrelation between migration and gender. FEMINA (FErtility, MIgratioN and Acculturation) aims to investigate intersectional SRH inequalities among Cape Verdean immigrant and Portuguese native families and how they impact on fertility in Portugal. This study will use a comprehensive approach exploring simultaneously the components of SRH, namely regarding identities, perceptions and practices of both women and men among lay people and relevant experts and stakeholders. The project has three main goals: 1) to identify social determinants of SRH among Cape Verdean immigrant and Portuguese native men and women of reproductive age; 2) to gain understanding of the diversity of the sexual and reproductive experiences and expectations of Cape Verdean immigrant and Portuguese native men and women of reproductive age, considering the singularities of their migratory, social and family dynamics; and 3) to produce recommendations for policy makers, employers and service providers on how to better address the SRH needs of Portuguese-born and immigrant populations. METHODS: The study will address these goals using a mixed methods approach, including: a cross-sectional telephone survey with a probabilistic sample of 600 Cape Verdean immigrant and 600 Portuguese native women and men (women aged 18 to 49 and men aged 18 to 54), residents of the Greater Lisbon Area; a qualitative research through in-depth interviews with a subsample of 30 Cape Verdean immigrants and 30 Portuguese native men and women; and a Delphi technique for finding consensus on good practices in SRH for the entire population with a special emphasis on immigrants, namely extra-EU migrants. DISCUSSION: Data will be used to produce a comprehensive set of indicators to monitor SRH in Portugal, to foster a greater understanding of its specificities and challenges to policy and decision makers, and to provide targeted recommendations to promote inclusive and migrant sensitive SRH services.

RESUMO

Objectives: Self-perceived health declines with age, varies by gender and is a predictor of mortality, morbidity, physical and psychological functioning. However, gender differences in health and illness perception are complex and not yet fully understood. This study aimed to explore gender-related differences in psychosocial determinants of self-perceived health among older adults living in nursing homes. Method: Nationwide face-to-face survey of the Portuguese population aged 65 and over. A representative sample of nursing homes residents was obtained through a multistage cluster random sampling of nursing homes, stratified by main Portuguese administrative regions (NUTS II). Results: Overall, 1186 nursing homes residents voluntarily enrolled in this study (participation rate, 93%) and a total of 515 participants (70.1% women) were considered to have adequate cognitive functioning to answer all questionnaires. A significant association between self-rated health and gender was found: 90.6% of all women (95% CI: 85.7-93.9) and 82.3% of all men (95% CI: 72.9-88.9) rated their health as less than good (p = 0.023). Gender-stratified analyses showed differences in psychosocial determinants of self-perceived health. While symptoms of depression and loneliness feelings were the major psychosocial determinants of poor self-perceived health among women, age and subjective financial well-being were the only determinants among men. Conclusion: Factors associated with perceived health, as representative of healthy ageing, were identified by gender, leading to future avenues for fruitful investigation. The acknowledgement of interpersonal and socioeconomic factors that determine the experience of ageing at a national level is crucial to improve the health of elders.

RESUMO

OBJECTIVE: To characterise the nutritional status and to identify malnutrition-associated variables of older adults living in Portuguese nursing homes. DESIGN: Cross-sectional study. Data on demographic and socio-economic characteristics, self-reported morbidity, eating-related problems, nutritional status, cognitive function, depression symptoms, loneliness feelings and functional status were collected by trained nutritionists through a computer-assisted face-to-face structured interview followed by standardised anthropometric measurements. Logistic regression was used to identify factors associated with being at risk of malnutrition/malnourished. SETTING: Portuguese nursing homes. SUBJECTS: Nationally representative sample of the Portuguese population aged 65 years or over living in nursing homes. RESULTS: A total of 1186 individuals (mean age 83·4 years; 72·8 % women) accepted to participate. According to the Mini Nutritional Assessment, 4·8 (95 % CI 3·2, 7·3) % were identified as malnourished and 38·7 (95 % CI 33·5, 44·2) % were at risk of malnutrition. These percentages increased with age and were significantly higher for women. Logistic regression showed (OR; 95 % CI) that older adults reporting no or little appetite (6·5; 2·7, 15·3), those revealing symptoms of depression (2·6; 1·6, 4·2) and those who were more dependent in their daily living activities (4·7; 2·0, 11·1) were also at higher odds of being malnourished or at risk of malnutrition. CONCLUSIONS: Malnutrition and risk of malnutrition are prevalent among nursing home residents in Portugal. It is crucial to routinely screen for nutritional disorders, as well as risk factors such as symptoms of depression and lower functional status, to prevent and treat malnutrition.

RESUMO

BACKGROUND: Economic crises and unemployment have profound impact on mental health and well-being. Main goal of the Healthy Employment (HE) project is to enhance intersectoral actions promoting mental health among unemployed, namely through the implementation and effectiveness-evaluation of short-term and sustainable group interventions. METHODS: The project follows a RE-AIM-based (Reach, Effectiveness, Adoption, Implementation and Maintenance) framework for assessing a cognitive-behavioural and psychoeducational intervention that has been developed for promoting mental health among unemployed people. It is a short-term group intervention (five sessions, four hours each, 20 unemployed persons per group) focused on mental health literacy, interpersonal communication and of emotional regulation. Implementation of the intervention will be carried out by clinical psychologists, following a standardized procedure manual. Effectiveness will be assessed through a randomized field study with two arms (intervention and control). Participants are unemployed people (18-65 years old, both genders, having at least nine years of formal education) registered at public employment centres from different geographical regions for less than 12 months (including first-job seekers). Allocation to arms of the study will follow a random match-to-case process, considering gender, age groups and educational level. Three moments of evaluation will occur: before intervention (baseline), immediately after its ending and three months later. Main outcomes are mental health literacy, mental health related personal and perceived stigma, psychological well-being, satisfaction with life and resilience. Intention-to-treat and per-protocol analyses will be conducted. Cohen's d coefficient and odds ratio will be used for assessing the size of the intervention effect, when significant. DISCUSSION: Scientific and clinical knowledge will be applied to promote/protect psychological well-being of unemployed people. While the first phases of the project are funded by the European Economic Area Grants, long-term assessments of the intervention require a larger timeframe. Further funding and institutional support will be sought for this purpose. Already established intersectoral collaborations are key-assets to reach long-term sustainability of this project. TRIAL REGISTRATION: The study was registered with the Australian New Zealand Clinical Trials Registry; Prospectively registered number: ACTRN12616001432404 ; date of registration: 13 October 2016.

RESUMO

BACKGROUND: Cancer screening has contributed to downward trends in cancer mortality, but is also associated with adverse effects, which highlights the importance of promoting the participation based on informed decisions. OBJECTIVES: We aimed to describe the use of cancer screening (either in organized programmes or as opportunistic screening), awareness of organized programmes and perception of its potential benefits and adverse effects, depicting possible sex differences. DESIGN AND METHODS: We evaluated 1624 Portuguese-speaking dwellers, aged between 16 and 79 years, through face-to-face interviews. To quantify sex differences, adjusted prevalence ratios and respective 95% confidence intervals were computed using Poisson regression. RESULTS: Among eligible age groups, the lifetime prevalence of screening for breast and cervical cancers was 89.8 and 71.9%, respectively. The prevalence was 23.7% for colorectal cancer and no significant sex differences were observed. Prostate cancer screening was reported by 63.8% of men. Over half of the participants referred that cancers such as prostate, skin, lung and stomach should be screened for, in addition to those for which organized programmes are recommended. Reassurance by negative results was identified as the main potential benefit of screening by nearly one-third of men and women. Anxiety while waiting for results was the most mentioned potential adverse effect (60.4%); men refer less often this and financial costs, although statistical significance of these results was borderline. CONCLUSIONS: This study provides a benchmark to plan and monitor the effects of awareness-raising interventions, as well as for international comparisons across countries with different cancer prevention and control structures.

RESUMO

BACKGROUND/AIMS: Recently classified as an epidemic by the WHO, obesity (as well as the state of being overweight) clearly affects significant populations across all ages. The relationship between obesity and some diseases (e.g. cardiovascular ones) is known, although many paradoxes remain to be explained. Very little information is available, however, regarding its impact on skin physiology and skin disease. This study aims to examine the influence of excessive weight on epidermal hydration and transepidermal water loss, key variables of skin water balance and skin biomechanics. METHODS: A convenience sample of 89 healthy female volunteers was selected and divided into 4 groups, according to their BMI (body mass index), as normal (control), overweight, obese (I and II), and morbid. Skin physiology was quantitatively assessed in all individuals in 4 anatomical areas using non-invasive biometrical analysis by reference instrumentation. Descriptive and comparative statistics were applied, adopting a confidence level of 95%. RESULTS: A non-linear alteration for all variables was detected as a function of BMI. CONCLUSION: Results suggest that excessive weight might favour skin performance within certain limits, reflecting a particular adaptation of the skin to the weight gain and body contour.

RESUMO

PURPOSE: Rising rates of obesity have been recently associated to the novel concept of food addiction (FA). The Yale Food Addiction Scale (YFAS) is the most widely used measure for examining FA (1) and analysis of its reliability and validity is expected to facilitate empirical research on the construct. Here, we tested the psychometric properties of a Portuguese version of the YFAS (P-YFAS), establishing its factor structure, reliability and construct validity. METHODS: Data were obtained from 468 Portuguese individuals, 278 sampled from non-clinical populations, and 190 among obese candidates for weight-loss surgery. A battery of self-report measures of eating behavior was applied. RESULTS: Confirmatory factor analysis verified a one-factor structure with acceptable fit, with item analysis suggesting the need to eliminate item 24 from the P-YFAS. Internal consistency (KR-20 = .82) and test-retest stability were adequate. Correlation analyses supported convergent and divergent validity of the P-YFAS, particularly in the clinical sample. Both FA symptom count and diagnosis, according to the P-YFAS, adequately discriminated between samples, with classification of FA met by 2.5 and 25.8% of the participants in the non-clinical and clinical samples, respectively. CONCLUSIONS: These findings reinforce the use of P-YFAS in non-clinical and clinical populations. Future directions for extending YFAS validation are discussed.

RESUMO

BACKGROUND: Worldwide we are facing a serious demographic challenge due to the dramatic growth of the population over 60 years. It is expected that the proportion of this population will nearly double from 12 to 22 %, between 2015 and 2050. This demographic shift comes with major health and socio-economic concerns. Nutrition is a fundamental determinant of both health and disease and its role in extending a healthy lifespan is the object of considerable research. Notably, malnutrition is one of the main threats to health and quality of life among the elderly. Therefore, knowledge about nutritional status among the elderly is essential for the promotion and maintenance of healthy ageing and to support the development of health protection policies and equity in elderly health care. METHODS: This is a nationwide nutrition survey of the Portuguese population over 65 years old, with data collection through face-to-face interviews. A representative and random sample of community dwelling elderly and nursing homes residents will be obtained by multistage sampling stratified per main Portuguese regions, sex and age groups. Minimum sample size was estimated to be 2077 elderly (979 in the community and 1098 in nursing homes). Data will be collected on food habits and eating patterns, nutritional status, food insecurity, lifestyle, self-rated general health status and self-reported diseases, functionality, loneliness, cognitive function, emotional status and demographic and socio-economic characterization. DISCUSSION: This is the first national survey to evaluate the prevalence of nutritional risk and malnutrition of the Portuguese population above 65 years old, including those living in nursing homes. It will allow the identification of population subgroups of elderly with increased odds of malnutrition and nutritional risk. In addition, this survey will contribute to the identification of psychosocial and clinical predictors of malnutrition among elderly, which is an important risk factor for other devastating medical conditions.

RESUMO

PURPOSE: Several health-related quality-of-life (HRQoL) dimensions are affected by obesity. Our goal was to characterize the psychometric properties of the ORWELL-R, a new obesity-related quality-of-life instrument for assessing the "individual experience of overweightness". METHODS: This psychometric assessment included two different samples: one multicenter clinical sample, used for assessing internal consistency, construct validity and temporal reliability; and a community sample (collected through a cross-sectional mailing survey design), used for additional construct validity assessment and model fit confirmation. RESULTS: Overall, 946 persons participated (188 from the clinical sample; 758 from community sample). An alpha coefficient of 0.925 (clinical sample) and 0.934 (community sample) was found. Three subscales were identified (53.2 % of variance): Body environment experience (alpha = 0.875), Illness perception and distress (alpha = 0.864), Physical symptoms (alpha = 0.674). Adequate test-retest reliability has been confirmed (ICC: 0.78 for the overall score). ORWELL-R scores were worse in the clinical sample. Worst HRQoL, as measured by higher ORWELL-R scores, was associated with BMI increases. ORWELL-R scores were associated with IWQOL-Lite and lower scores in happiness. CONCLUSIONS: ORWELL-R shows good internal consistency and adequate test-retest reliability. Good construct validity was also observed (for convergent and discriminant validity) and confirmed through confirmatory factor analysis (in both clinical and community samples). Presented data sustain ORWELL-R as a reliable and useful instrument to assess obesity-related QoL, in both research and clinical contexts.

RESUMO

Introduction: Computer confidence and computer self-efficacy can impact an individual's perceived ease of use and usefulness of technology, ultimately determining adherence to digital healthcare services. However, few studies focus on assessing the impact of non-clinical factors on the efficacy and adherence to digital healthcare platforms. Objective: We aimed to analyse the role of non-clinical factors (i.e. computer confidence and computer self-efficacy) in the interaction experience (IX) and the feasibility of a digital neuropsychological platform called NeuroVRehab.PT in a group of older adults with varying levels of computer confidence. Methods: Eight older adults (70.63 ± 6.1 years) evaluated the platform, and data was collected using the Think-Aloud method and a semi-structured interview. Sessions were audio-recorded and analysed through an inductive-deductive informed Thematic Analysis protocol. This study was conducted according to the Consolidated Criteria for Reporting Qualitative Research guidelines. Results: Three main themes were identified (Interaction Experience, Digital Literacy, and Attitudes toward NeuroVRehab.PT). Computer anxiety and fear of making errors were not uncommon, even among older adults who perceive themselves as confident in technology use, and negatively impacted IX. Moreover, some game elements (e.g. three-star system, progression bar) were not intuitive to all participants, leading to misleading interpretations. On the other hand, human support and the platform's realism seemed to impact participants' IX positively. Conclusions: This study shed light on the barriers raised by non-clinical factors in adopting and using digital healthcare services by older adults. Furthermore, a critical analysis of the platform's features that promote user adoption is done, and suggestions for overcoming limitations are presented.

RESUMO

In Portugal, like in other European countries, the COVID-19 pandemic aggravated the risk of poverty and social exclusion faced by migrants. This study aimed to assess mental health and well-being, and their social determinants, among Brazilian and Cape Verdean immigrant populations two years after the COVID-19 pandemic while exploring the role of positive psychological factors such as resilience and perceived social support. We conducted a cross-sectional survey combining online and face-to-face questionnaires for data collection between February and November 2022 on dimensions of mental health considered potentially relevant to the post-pandemic context: psychological distress, anxiety, and depression. Overall, 604 immigrants were included (322 Brazilian and 282 Cape Verdean); 58.5% of those surveyed were women and 41.5% were men. The results revealed that gender (being a woman) was associated with both psychological distress and depression, higher education was associated with anxiety, and that, for the three mental health dimensions under analysis, the perception of discrimination and resilience were negative and positive predictors, respectively. Findings can inform the design and implementation of relevant public mental health promotion programs with a focus on equity targeted to the general population. Such programs would help to address the psychological and social impacts of this long-term, insidious global pandemic that has challenged governments, health care systems, health care professionals, individuals, families, and communities worldwide.

RESUMO

The COVID-19 pandemic increased psychosocial risk factors among healthcare professionals (HCPs). Objective: To characterize Portuguese HCPs mental health (MH), estimate anxiety, depression, post-traumatic stress disorder (PTSD) and burnout symptoms, and identify risk/protective factors. A cross-sectional online survey and a longitudinal assessment were conducted in 2020 (T0) and 2021 (T1). Sociodemographic and occupational variables, COVID-19-related experiences and protective behavior data were collected from a non-probabilistic sample of HCPs in Portugal. Symptoms of anxiety, depression, PTSD, burnout and resilience were assessed using the Portuguese versions of the Generalized Anxiety Disorder Scale (GAD-7), the Patient Health Questionnaire (PHQ-9), the Post-traumatic Stress Disorder Checklist (PCL-5), the Shirom-Melamed Burnout Measure (MBSM) and the Connor-Davidson Resilience Scale (CD-RISC-10), respectively. Risk and protective factors were identified through simple and multiple logistic regression models. Overall, 2027 participants answered the survey in T0 and 1843 in T1. The percentage of moderate-to-severe symptoms decreased from T0 to T1; however, a considerable proportion of HCPs reported symptoms of distress in both years. Being a woman, working in a COVID-19-treatment frontline position and work-life balance increased the odds of distress. High resilience, good social/family support, and hobbies/lifestyle maintenance were found to be protective factors. Globally, our results show that performing as a HCP during the pandemic may result in long-term effects on MH.
