ABSTRACT
This study aims to verify the concurrent validity of the paper, and the telephone versions of the instrument used to evaluate the effectiveness of the Vida Ativa Melhorando a Saúde (VAMOS) Pro-gram participants. The VAMOS Program is a community-based intervention aiming at motivating people to adopt an active and healthy lifestyle. The study population was adults registered at the Basic Health Units in the state of Santa Catarina, and the sample for the validity test was two groups that concluded the program. To compare each variable provided by paper and telephone format, multi-level generalized linear and logistic models were carried out, adjusted by age, sex, and educational level. As a result, it was possible to identify the validity of most of the questions, with variations in the frequency of cooked vegetable consumption, method of preparing animal meat, frequency of physical activity, and waist circumference. We concluded that the use of the telephone survey could be considered for VAMOS Program effectiveness evaluation

ABSTRACT
Enzymes with multiple distinct active sites linked by substrate channels combined with control over the solution environment near the active sites enable the formation of complex products from simple reactants via the confinement of intermediates. We mimic this concept to facilitate the electrochemical carbon dioxide reduction reaction using nanoparticles with a core that produces intermediate CO at different rates and a porous copper shell. CO2 reacts at the core to produce CO which then diffuses through the Cu to give higher order hydrocarbon molecules. By altering the rate of CO2 delivery, the activity of the CO producing site, and the applied potential, we show that the nanoparticle with lower activity for CO formation produces greater amounts of hydrocarbon products. This is attributed to a combination of higher local pH and the lower amount of CO, resulting in more stable nanoparticles. However, when lower amounts of CO2 were delivered to the core, the particles that are more active for CO formation produce more C3 products. The importance of these results is twofold. They show that in cascade reactions, more active intermediate producing catalysts do not necessarily give greater amounts of high-value products. The effect an intermediate producing active site has on the local solution environment around the secondary active site plays an important role. As the less active catalyst for producing CO also possesses greater stability, we show that nanoconfinement can be used to get the best of both worlds with regard to having a stable catalyst with high activity.
ABSTRACT
Abstract This study aimed to validate the frequency consumption scale (FCS) and establish cut-off points to assess changes in the eating behavior of participants in the VAMOS Program. The study was based on a community intervention conducted in 2019 in 70 Brazilian cities, with 458 adults from Primary Care. The questionnaire consisted of 12 questions about food frequency consumption. The questions were inserted into the analytical workflow, divided into the descriptive analysis, exploratory and confirmatory factor analysis (EFA), item response theory (IRT) modeling, and construction and validity of an applied questionnaire score. EFA indicated a two-factor structure, with three "healthy" (raw vegetables, fruits, and cooked vegetables) and three "unhealthy" (sugary drinks, sweets, and the replacement of meals with snacks) eating items. Items responses' probabilities indicate a daily consumption of two healthy and once or nonweekly consumption of unhealthy items. Finally, the four categories proposed for FCS can respond over time. Therefore, the FCS proposal can be used effectively for program nutrition evaluation. Furthermore, it is possible to attribute behavior change in Brazilian primary care users with six items.
Resumo Este estudo teve como objetivo validar a escala de consumo de frequência (ECF) e estabelecer pontos de corte para avaliar mudanças no comportamento alimentar dos participantes do Programa VAMOS. O estudo baseou-se em uma intervenção comunitária realizada em 2019 em 70 cidades brasileiras, com 458 adultos da Atenção Básica. O questionário era composto por 12 questões sobre o consumo de frequência alimentar. As questões foram inseridas no fluxo de trabalho analítico, divididas em análise descritiva, análise fatorial exploratória e confirmatória (EFA), modelagem da teoria de resposta ao item (TRI) e construção e validade de um escore de questionário aplicado. EFA indicou uma estrutura de dois fatores, com três itens alimentares "saudáveis" (vegetais crus, frutas e vegetais cozidos) e três "não saudáveis" (bebidas açucaradas, doces e a substituição de refeições por lanches). As probabilidades das respostas dos itens indicam um consumo diário de dois itens saudáveis e um consumo único ou não semanal de itens não saudáveis. Por fim, as quatro categorias propostas para o ECF podem fornecer respostas ao longo do tempo. A proposta do ECF pode ser usada efetivamente para avaliação nutricional do programa. Além disso, é possível atribuir a mudança de comportamento em usuários da atenção básica brasileira com seis itens.

BACKGROUND: Knowing what facilitates and hinders physical activity behaviour across domains (leisure, travel, work or education, and household) is central for the development of actions for more active lifestyles. Thus, the aim of this systematic review of reviews was to summarize the evidence on barriers and facilitators of domain-specific physical activity. METHODS: We included systematic reviews with or without meta-analysis that investigated the association between modifiable barriers and facilitators and levels of domain-specific physical activity. Reviews published until September 2020 were retrieved from PubMed, ISI Web of Science, Scopus, Regional Library of Medicine (BIREME), and PsycNET, and from the reference list of selected articles. Each review was screened by two independent reviewers for eligibility. Data extracted from selected papers included methodological aspects (number of primary studies, study designs, and age groups); physical activity domains and barriers and facilitators investigated; and direction of association. For each pair of barrier/facilitator and domain-specific physical activity, we recorded the number of positive, negative, and null associations reported across reviews. Quality assessment of each systematic review was performed using the AMSTAR-2 tool. RESULTS: Forty-four systematic reviews were selected. The evidence base was largest for leisure-time followed by travel-related physical activity. A very small number of reviews included physical activity in work, educational and domestic settings. Across all physical activity domains, factors related to the built environment were more abundant in the reviews than intra and interpersonal factors. Very consistent positive associations were observed between a range of intrapersonal factors and leisure-time physical activity, as well as moderately consistent evidence of positive association for general social support and support from family members. Evidence of moderate consistency was found for the positive association between transport-related physical activity and positive beliefs about consequences, walkability, and existence of facilities that support active travel. Evidence on barriers and facilitators for physical activity at work, educational, and domestic settings was limited in volume and consistency. CONCLUSIONS: Efforts and resources are required to diversify and strength the evidence base on barriers and facilitators of domain-specific physical activity, as it is still limited and biased towards the leisure domain and built environment factors.

Introduction: The effective translation of evidence-based interventions has contributed to implementing actions that impact public policies and the population's health. However, there is a gap in the literature regarding the factors associated with the successful implementation of these interventions. The Active Life Improving Health Behavior Change Program (BCP-VAMOS) uses behavioral strategies to promote an active and healthy lifestyle in the community. Characterized as a health innovation, it also provides health professionals with online training to implement the program in Primary Health Care (PHC). Our study describes a pragmatic trial that aims to evaluate the implementation of BCP-VAMOS, version 3.0, in PHC in southern Brazil. Methods and analysis: A pragmatic randomized controlled trial (PRCT) of two arms comparing a group of PHC professionals who will participate in a traditional didactic approach (control group) vs. a group that will receive ongoing support (intervention group) for the implementation of BCP-VAMOS. The intervention will be available to adults (≥18 years old) registered at PHC. Program recipient's will be assessed at baseline and post-intervention (9 months after) to measure markers of physical activity and eating behavior (primary outcomes). Program's implementation process will be monitored for 12 months and will be evaluated using the RE-AIM and Consolidated Framework for Implementation Research (CFIR) frameworks. Discussions: The survey findings can be used widely throughout Brazil, guiding the work of health professionals, service planners and policy-makers. Also, the results may help to inform the national health promotion policy to plan interventions and improve the implementation of programs in PHC. This research results will provide practical guidance for researchers to develop similar protocols to implement and adapt public health interventions. Ethics and dissemination: Ethics approval has been granted by the Human Research Ethics Committee of the Federal University of Santa Catarina (UFSC), Brazil, under no. 1394492. Results will be published in full as open access in the UFSC library and main trial results and associated papers in high-impact peer-reviewed journals. Trial registration number: RBR-2vw77q-Brazilian Registry of Clinical Trials - ReBEC (http://www.ensaiosclinicos.gov.br).

Abstract This study aimed to systematically review scientific evidence on the barriers and facilitators of physical activity (PA) among the Brazilian population, considering different domains (leisure, travel, work/study, and household). The search was conducted in the MEDLINE/PubMed, ISI Web of Science, SCOPUS, BIREME/LILACS, and APA PsycNET databases and was limited to papers published between 2010 and 2020. A manual search of the Brazilian Journal of Physical Activity & Health was also conducted. The selection process consisted of screening titles and abstracts, followed by the analysis of full texts. Each paper was assessed by two independent reviewers, and when discrepancies arose, a third reviewer was consulted. Leisure, environmental barriers and facilitators were the most investigated domains in the 78 included studies. There was consistency in the positive associations between six different intrapersonal and social facilitators for leisure PA and one environmental factor for travel. There have been a small number of investigations on the work/study and household domains, and future investigations on intrapersonal and social barriers and facilitators in the travel domain are important.

Barriers and facilitators influence the implementation of physical activity (PA) in Primary Health Care (PHC). This study aimed to analyze the scientific evidence on barriers and facilitators perceived by stakeholders on the implementation of PA in PHC.The search databases consisted of Web of Science, Medline, Scopus, and Lilacs. Two independent researchers reviewed the eligibility criteria and extracted and coded the information according to the Theoretical Domains Framework (TDF). The Consolidated Criteria for Reporting Qualitative Research was used to report the quality of the included studies. We analyzed 8.471 studies but included only 16. The studies identified 54 different reports on barriers and 48 on facilitators. Reports were often identified in the "environmental context and resources" domain, with 27 reports on barriers and 27 on facilitators. We found 25 reports of barriers and 16 of facilitators in the TDF domains that demonstrate professional profile characteristics. The low expectations in the professional profile for the implementation can influence the context and the organizational climate to identify more barriers than facilitators.
ABSTRACT
Creating high surface area nanocatalysts that contain stacking faults is a promising strategy to improve catalytic activity. Stacking faults can tune the reactivity of the active sites, leading to improved catalytic performance. The formation of branched metal nanoparticles with control of the stacking fault density is synthetically challenging. In this work, we demonstrate that varying the branch width by altering the size of the seed that the branch grows off is an effective method to precisely tune the stacking fault density in branched Ni nanoparticles. A high density of stacking faults across the Ni branches was found to lower the energy barrier for Ni2+/Ni3+ oxidation and result in enhanced activity for electrocatalytic oxidation of 5-hydroxylmethylfurfural. These results show the ability to synthetically control the stacking fault density in branched nanoparticles as a basis for enhanced catalytic activity.

The use of nanoparticles and nanostructured electrodes are abundant in electrocatalysis. These nanometric systems contain elements of nanoconfinement in different degrees, depending on the geometry, which can have a much greater effect on the activity and selectivity than often considered. In this Review, we firstly identify the systems containing different degrees of nanoconfinement and how they can affect the activity and selectivity of electrocatalytic reactions. Then we follow with a fundamental understanding of how electrochemistry and electrocatalysis are affected by nanoconfinement, which is beginning to be uncovered, thanks to the development of new, atomically precise manufacturing and fabrication techniques as well as advances in theoretical modeling. The aim of this Review is to help us look beyond using nanostructuring as just a way to increase surface area, but also as a way to break the scaling relations imposed on electrocatalysis by thermodynamics.

ABSTRACT BACKGROUND: Multimorbidity due to non-communicable chronic diseases (NCDs) constitutes a significant challenge for healthcare systems. To attenuate its impacts, it is essential to identify the sociodemographic determinants of this condition, which can discriminate against population segments that are more exposed. OBJECTIVE: To identify associations between multimorbidity conditions and sociodemographic indicators among Brazilian adults and older adults. DESIGN AND SETTING: Cross-sectional telephone-based survey in 26 Brazilian state capitals and the federal district. METHODS: The Vigitel 2013 survey was used, with data collected via a questionnaire. The outcome was multimorbidity (2, 3 or 4 NCDs), and the exposures were sociodemographic indicators (age, sex, skin color, marital status and education). The analysis consisted of multinomial logistic regression (odds ratio), stratified by age. RESULTS: Among adults, multimorbidity comprising two, three or four diseases was associated with advancing age (P < 0.001); two and three diseases, with having a partner (P = 0.004 and P < 0.001, respectively); and two, three or four diseases, with lower education (P < 0.001). Among older adults, two, three or four diseases were associated with female sex (P < 0.001); three diseases, with living with a partner (P = 0.018); two diseases, with black skin color (P = 0.016); and two or three diseases, with lower education (P < 0.001). CONCLUSIONS: To control and prevent multimorbidity, strategies for individuals with existing chronic diseases, with partners and with lower education levels are needed. Particularly for adults, advancing age should be considered; and for older adults, being a woman and having black skin color.

This study described the clustering patterns of moderate to vigorous physical activity and sedentary time (ST) according to handgrip strength and investigated the association between identified clusters of fat and lean mass in older adults from southern Brazil. Objective measures were used for moderate to vigorous physical activity, ST, and body composition outcomes. Two-step cluster and linear regression analyses were conducted according to handgrip strength. Three clusters were identified: all-day sitters, sitters, and active sitters. The prevalence of clusters in the low-strength group was 58.2%, 22.8%, and 19.0%, respectively, while the prevalence of clusters in the high-strength group was 42.1%, 34.8%, and 23.1%, respectively. All-day sitters had 2.6% more fat mass than active sitters with low strength. High levels of ST characterized all cluster profiles; low strength, lack of moderate to vigorous physical activity, and high ST levels among older adults may indicate a subpopulation at a greater risk of overweight and obesity-related diseases.

Participaram da pesquisa 34 idosas com excesso de peso divididas em dois grupos: Grupo Intervenção (GI; n=17) com média de idade de 69,2±5,8 anos e Grupo Controle (GC; n=17) com 69,9±6,0 anos. O GI participou de 12 encontros semanais, durante três meses, do VAMOS programa de mudança de comportamento que objetiva motivar as pessoas a adotarem um estilo de vida ativo e saudável. Ambos os grupos praticaram ginástica duas vezes por semana e realizaram avaliações no início e ao final do Programa. Foram realizadas avaliações sociodemográficas, antropométricas, de nível de atividade física e do comportamento alimentar. Os resultados demonstraram que o programa VAMOS teve uma taxa de alcance de 27,5% e manteve a circunferência do quadril (CQ). Quanto à alimentação, foi identificado aumento no preparo de carnes na forma não fritura e diminuição no preparo de frituras em ambos os grupos (p=0,012). Conclui-se que o Programa VAMOS foi efetivo em não aumentar a CQ de idosas com excesso de peso.(AU)
This study has as aim to verify the reach and effectiveness of the Active Life Improving Health Program on the physical activity level, eating behavior and anthropometric variables in overweight elderly women participating in the extension project "Physical Activity for Third Age". Thirty-four overweight elderly women participated in the research, divided into two groups: Intervention Group (IG; n = 17), with a mean age of 69.2 ± 5.8 years; and Control Group (CG; n = 17), with 69.9 ± 6.0 years. IG participated in 12 weekly meetings, during three months of VAMOS, which is a behavior change program that aims to motivate people to adopt an active and healthy lifestyle. Both groups practiced gymnastics twice a week and performed evaluations at the beginning and the end of the program. Sociodemo- graphic, anthropometric, physical activity level and eating behavio assessments were collected. The results showed that the VAMOS program had a reach rate of 27.5% and maintained the hip circumference (HC). Regarding food, it was identified an increase in meat preparation in the non-fried form and a decrease in the preparation as fried in both groups (p = 0.012). It is concluded that the VAMOS Program was effective in not increasing the HC of elderly women with overweight.(AU)

ABSTRACT BACKGROUND: Associations between behaviors and individual chronic diseases have been demonstrated. However, the relationship between time spent on sedentary behavior and multimorbidity remains less clear. OBJECTIVE: To identify the predictive power of various intensities of physical activity versus sedentary behavior, as discriminatory factors for cardiometabolic multimorbidity (cardiovascular diseases and diabetes) in the elderly. DESIGN AND SETTING: Cross-sectional study in different residential census tracts and residential households in Florianópolis (SC). METHODS: The participants were 425 elderly people (65% women) from the EpiFloripa Aging study in 2014. Sociodemographic variables and self-reported incidence of cardiovascular diseases and diabetes were obtained via a questionnaire. Light physical activity (LPA), moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB) were measured using accelerometers. The analyses were stratified according to sex and included a diagnosis for interpretation. Behaviors were taken into consideration if their predictive power in terms of area under the receiver operating characteristic (ROC) curve was greater than 0.50. The time cutoff point was defined from sensitivity and specificity. RESULTS: For older adult men with diabetes, the predictive value of MVPA for absence of multi-morbidity was an area of 0.75 (95% confidence interval, CI: 0.538-0.962), and a cutoff of 17 minutes per day. Older adult women with diabetes had an area of 0.71 (95% CI: 0.524-0.866) and a cutoff of 10 minutes per day. LPA and SB did not present predictive values. CONCLUSION: The time spent on MVPA is a predictor of absence of multimorbidity in elderly people with diabetes, for both sexes.
