Leisure-Time Physical Activity in a Southern Brazilian City (2004-2021): Applying an Equity Lens to Time-Trend Analyses.

BACKGROUND: This study aimed to verify leisure-time physical activity trends over 15 years and monitor inequalities according to gender, self-reported skin color, and socioeconomic position in a Southern Brazilian city. A secondary aim is to evaluate intersectionalities in physical activity. METHODS: Trend analysis using 3 population-based surveys carried out in 2004, 2010, and 2021. Main outcome assessed was the prevalence of physical activity according to recommendations (150 min/wk). Inequalities dimensions measured were sex, self-reported skin color, and wealth. Intersectionalities were evaluated using Jeopardy index combining all inequality dimensions. Trend analysis was performed using least-squares weighted regression. RESULTS: We included data from 3090, 2656, and 5696 adults in 2004, 2010, and 2021, respectively. Prevalence of physical activity remains stable around 25% in the 3 years. In the 3 periods evaluated, men presented a prevalence in average 10 percentage points higher than women (SII2004 = -11.1 [95% confidence interval, CI, -14.4 to -7.8], SII2021 = -10.7 [95% CI, -13.7 to -7.7]). Skin color inequalities did not present a clear pattern. Richest individuals, in general presented a prevalence of leisure-time physical activity level 20pp higher than poorest ones (SII2004 = 20.5 [95% CI, 13.7 to 27.4]; SII2021 = 16.7 [95% CI, 11.3 to 22.0]). Inequalities were widely marked, comparing the most privileged group (represented by men, the wealthiest, and White) and the most socially vulnerable group (represented by women, the poorest, and Black/Brown). The Slope Index of Inequality for intersectionalities was -24.5 (95% CI, -31.1 to -17.9) in 2004 and -18.8 in 2021 (95% CI, -24.2 to -13.4). CONCLUSIONS: Our analysis shows that women, Black/Brown, and poor present lower leisure-time physical activity level. This group is often neglected regarding other health and social outcomes.

Examining motivation factors for African American students' use of consumer wearables.

Purpose: This study was initiated to examine factors that motivate African American students who use wearable devices at an HBCU in Mississippi. Method: We conducted a correlational research study on undergraduate and graduate students from a southern USA university. The stratified random sample comprised a total of 239 students. The responses of the students were analyzed using the Fisher exact test to determine whether or not there was a significant association between the categorical demographic variables (age, gender, ethnicity, and student classification) and the students' motivation for using a wearable device. Results: Students used wearables for one main reason, to help them increase their awareness of their health status because they understand the importance of tracking their health metrics to boost their health status and reduce risk factors for developing chronic diseases. Students also demonstrated that they understand the value of tracking health information, such as heart rate and blood pressure, as a way to reduce the prevalence and impact of risk factors that can lead to chronic diseases. Conclusions: Wearables enable individuals to regularly observe, measure, and record their physical status and physiological measures, and facilitate medication adherence by enabling individuals to maintain their prescribed medication regimen adequately. The data collected and stored through these wearables can provide data that will be useful for medical personnel in their treatment of patients and in developing strategies for prevention and intervention for the larger community.

Physical activity and health: a historical and conceptual approach / A relação entre atividade física e saúde: uma abordagem histórica e conceitual

This theoretical essay reflects on physical activity (PA) and health and the development of this study area, particularly in Brazil. A historical review is presented based on major research themes in the area since the 1950s and the evolution of PA recommendations for health. Crucial conceptual and operational definitions in the area that have gone through recent updates are addressed. The pa-per highlights relevant institutions and documents, as well as reflects on future perspectives and challenges in the field. Finally, this essay highlights the need to reduce the gap between the robust scientific knowledge already produced about the health benefits of PA and the real action in the field, especially in the primary health care setting

A partir de uma abordagem histórica, conceitual, crítica e didática, este ensaio teórico propõe uma reflexão sobre a relação entre atividade física (AF) e saúde e o desenvolvimento desta área de estudo, com um olhar especial sobre o Brasil. Apresenta-se revisão histórica a partir de grandes temas de pesquisa na área desde os anos 1950 e da evolução das recomendações de AF para a saúde. São abordadas definições conceituais e operacionais que passaram por atualizações recentes e que são cruciais na área. Faz-se destaque a instituições e documentos relevantes, além de reflexões sobre perspectivas e desafios futuros para a área. Por fim, destaca a necessidade da redução na distância entre a solidez do conhecimento já produzido sobre os benefícios da AF para a saúde e os desejados avanços no contexto da promoção da saúde, em especial na atenção primária à saúde

Mississippi church leaders' perceptions of challenges and barriers to the use of consumer wearables among community members.

Background: Wearables have begun to play a transformative role in health management and disease prevention. Objective: This study examined the use of wearable devices in African American communities in Mississippi, USA, through the lens of church leaders. Methods: We conducted focus groups with church leaders to record their perceptions about the use of wearables of their community members. We conducted six focus groups with a total of 89 church leaders from across the state of Mississippi. The focus groups were designed to contextualize and explain the socio-cognitive processes that provided an understanding of wearable device adoption practices among community members. Participants were male and female church leaders who were recruited from the three Mississippi Districts. The church leaders' perceptions of barriers and challenges to the adoption of consumer wearables in their communities were thoroughly analyzed using thematic analysis. Results: There was great apprehension on the part of community members about the security of the information they entered into the wearable devices and about how that information could be used by other parties. Many community members who understood the value of proactive health behaviors could not afford the high cost of purchasing wearable devices, while others displayed a low level of comfort with technology, believing that wearable use was for younger people. Conclusion: More expansive adoption of wearable devices in Mississippi will depend on the ability of the public health professionals, policy-makers and manufacturers to address the barriers that were identified by this study, thereby enabling the community to have full access to the potential benefits of these technologies.

Efficacy testing of the SAVOR (Sisters Adding Fruits and Vegetables for Optimal Results) intervention among African American women: A randomized controlled trial.

Background: In the United States, only about 15% of individuals meet daily fruit intake recommendations of 2 cups per day and only 10% meet the vegetable intake recommendations of3 cups per day. African American women are a high-risk group. In this study, a fourth-generation multi-theory model (MTM) of health behavior change was used to design and evaluate a SistersAdding Fruits and Vegetables for Optimal Results (SAVOR) intervention for AA women. Methods: The study utilized a randomized controlled trial (RCT) with measurements taken at pretest, posttest (after the three-week intervention) and follow-up (at the end of eight weeks).SAVOR (n=26) was compared to an equivalent knowledge-based intervention (n=28). Process evaluation was done for program fidelity and satisfaction. A validated 38-item self-reported questionnaire was used to measure changes in MTM constructs and past 24-hour consumption of fruits and vegetables. Results: The SAVOR intervention resulted in improvement of mean consumption of fruits and vegetables in the experimental group from pre-test (2.78) to posttest (4.77) to recommended levels at follow-up (5.04) while in the comparison group they remained at around 3 (P<0.0001)Statistically significant changes (P<0.05) were noted for all MTM constructs except for participatory dialogue. Conclusion: The SAVOR intervention was found to be efficacious and established the robustness of MTM. SAVOR can be replicated for future effectiveness trials.

Evaluation of multi-starter S. cerevisiae/ D. bruxellensis cultures for mimicking and accelerating transformations occurring during barrel ageing of beer.

During beer ageing, endogenous barrel microbes grow spontaneously and transform wort/beer composition, being Dekkera bruxellensis and Saccharomyces cerevisiae among the main contributors to the chemical and sensory profile of aged beer. This work aims at the application of multi-starter cultures to mimic and accelerate biological modifications occurring during barrel ageing of beer, in controlled fermentation processes. Co-cultures of D.bruxellensis/S.cerevisiae were conducted under conditions commonly found in barrel aged beer production: different pitching rates, high glucose concentration and presence of ethanol and wood extracts. Selective pressures and competition between yeasts influenced microbial growth and metabolite production, namely ethanol, acetic acid and target volatile compounds (esters, alcohols, terpenols, volatile acids and volatile phenols). Metabolic profiles of co-cultures combined traits of both species, and differed from those of pure cultures. Lastly, multi-starters were successfully applied in combination with wood in a controlled and accelerated fermentation process for mimicking barrel ageing transformations.

[Food intake according to the type of food consumed in schools in a rural area in southern Brazil]. / Consumo alimentar conforme o tipo de alimentação consumida em escolas de zona rural no Sul do Brasil.

The scope of the article was to evaluate food consumption according to the type of food consumed in rural schools. A cross-sectional descriptive study was conducted among adolescents enrolled in 12 rural public schools in Canguçu in the state of Rio Grande do Sul, Brazil. The research was linked to the intervention named "Physical Education +: Practicing Health in School." Dietary intake was evaluated using consumption markers from the Brazilian Food and Nutrition Surveillance System. The main independent variable was the type of food consumed at school (brought from home, provided by the school free of charge and/or purchased at school). Descriptive statistics and the Chi-square test were used and the significance level was p<0.05. The study enlisted 526 students, 51.3% female and 88.0% consuming food free of charge. From 15% to 31% of adolescents consumed foods considered unhealthy for more than three days in the preceding week. Students who reported taking a snack to school consumed raw salad, fresh fruit or fruit salad, biscuits/crackers and packet snacks and soft drinks more frequently. It was concluded that the consumption of healthy foods among schoolchildren in rural areas was low and interventions are needed to improve the current situation of inadequate feeding practices.

RESUMO Objetivou-se verificar o impacto da intervenção "Educação Física+: Praticando Saúde na Escola", sobre as práticas docentes e conhecimento em saúde de escolares da cidade de Canguçu/RS. Quinze escolas participaram do estudo (grupo 1- escolas que aderiram à intervenção no ano de 2011; grupo 2- escolas que aderiam à intervenção a partir do ano de 2012). O estudo teve duração de dois anos com 883 escolares e 13 professores. Houve aumento do nível de conhecimento dos escolares no pós-intervenção (p<0,001), com maiores médias no grupo 1; encontrou-se tendência de aumento do nível de conhecimento de acordo com o número de planos de aula desenvolvidos pelos professores (p<0,001). Dos professores entrevistados (n=13), a maioria aderiu às atividades propostas (n=8) e percebeu mudanças positivas, principalmente por parte dos alunos, que passaram a realizar mais questionamentos acerca da temática em sala de aula e levar tais conhecimentos para seus familiares. Quase a totalidade dos docentes que aderiram à proposta não relatou dificuldade em desenvolver os planos (n=7). Concluiu-se que uma intervenção de curto prazo melhorou o nível de conhecimento de escolares acerca da temática saúde e atividade física e apresentou impactos positivos na prática profissional dos docentes entrevistados.

ABSTRACT The objective was to verify the impact of "Educação Física+: Praticando Saúde na Escola" intervention on teaching practices and health knowledge of schoolchildren from Canguçu city, southern Brazil. Fifteen schools participated in the study (group 1: schools that joined the intervention in the year of 2011; group 2: schools that joined the intervention in the year of 2012). This study was carried out by two years with 883 schoolchildren and 13 teachers. The schollchildren knowledge of health was improved in the post-intervention (p<0.001), with higher scores in group 1. It was found tendency to increase the level of knowledge according to the number of lesson plans developed by teachers (p<0.001). Of the teachers interviewed (n= 13), most adhered to the activities proposed (n = 8) and perceived positive changes, specially in the students, who questioned more about the subject in the classrom and bring these knowledge to their parents. Almost all teachers who adhered to the intervention did not report difficulties to develop the lessons plans (n=7). It was concluded that a short-term intervention improved the schoolchildren level of knowledge on physical activity and health and presented positive impacts on teachers professional practice.

Drugs or disease: evaluating salivary function in RA patients.

Oral complications of RA may include temporomandibular joint disorders, mucosa alterations and symptoms of dry mouth. The aim of this study was to evaluate the salivary gland function of subjects with rheumatoid arthritis (RA) comparing it to healthy controls. Subjects with other systemic conditions known to affect salivary functions were excluded. A questionnaire was applied for the evaluation of xerostomia. Resting and chewing-stimulated salivary flow rates (SFR) were obtained under standard conditions. There were 145 subjects included of the study (104 RA and 38 controls). About 66.7% of the RA subjects and 2.4% in control group presented xerostomia. The median resting SFR were 0.24 ml/min for RA subjects and 0.40 mL/min for controls (p = 0.04). The median stimulated SFR were 1.31 mL/min for RA subjects and 1.52 ml/min for controls (p = 0.33). No significant differences were found between resting and stimulated SFR of RA subjects not using xerogenic medications and controls. There was significantly higher number of subjects presenting hyposalivation in the RA group than among controls, even when subjects using xerogenic medications were eliminated from the analysis. In conclusion, hyposalivation and xerostomia were more frequent among RA subjects not using xerogenic medication than among controls, although there were no significant differences in the median SFR between groups.

The prevalence of physical activity and its associated effects among students in the São Paulo public school network, Brazil.

The current study evaluated physical activity (PA) level and its associated effects among students in the public network of São Paulo, Brazil. A cross-sectional study was taken using a representative sample of students in São Paulo public school system. International Physical Activity Questionnaire determined PA level. Students who reported at least 300 minutes/week of PA were considered active. The independente variables were: gender, age, body mass index, education, region, recognition of the Agita São Paulo program. The prevalence of regular PA was 71.7%. Males (PR = 1.09, 95% CIs = 1.04 -1.15) at least 17 years old (PR = 1.16, 95% CIs 1.09-1.24) in their 3rd year of high school (PR = 1.20, 95% CIs = 1.12-1.29) who resided in the Midwest region (PR = 1.27, 95% CIs 1.16-1.38) were most likely to be active. Males at least 17 years old in their 3rd year of high school who lived in the Midwest and recognized the Agita São Paulo/Agita Galera program had higher levels of PA. São Paulo students presented a high level of PA. Moreover, males older than 17 years, attending their 3rd year of high school, who lived in the Midwest region, and recognized the Agita São Paulo/Agita Galera program were the most likely to be more active.

Prevalence of sedentary behavior and its correlates among primary and secondary school students / Prevalência de comportamento sedentário de escolares e fatores associados

To determine the students’ exposure to four different sedentary behavior (SB) indicators and their associations with gender, grade, age, economic status and physical activity level. Methods: A cross-sectional study was conducted in 2013. The SB was collected using the HELENA instrument, composed by screen time questions (TV, video games and internet) and sitting activities on school opposite shift. The cut point of ≥2h/day was used to categorize the outcome. The Poisson regression was used for associations between the outcome and the independent variables (95% significance level), controlling for confounding variables and the possible design effect. Results: The sample was composed by 8661 students. The overall prevalence of SB was 69.2% (CI95% 68.1–70.2) on weekdays, and 79.6% (CI95% 78.7–80.5) on weekends. Females were more associated with the outcome, except to electronic games. Advanced grades students were more involved in sitting tasks when compared to the early grades. Older students were more likely to surf on net for ≥2h/day. Higher economic level students were more likely to engage in video games and internet. Active individuals were less likely to engage in SB on weekdays. Conclusions: The prevalence of SB was high, mainly on weekends. The associations with sex, age, grade and physical activity level should be considered into elaboration of more efficient interventions on SB control.

Determinar a exposição de escolares a quatro indicadores diferentes de comportamento sedentário (CS) e suas associações com gênero, série escolar, idade, condição econômica e nível de atividade física. Métodos: Um estudo transversal foi feito em 2013. Os CS foram obtidos com o instrumento Helena, composto por perguntas sobre tempo de tela (TV, videogames e internet) e atividades na posição sentada na escola em relação ao turno. O ponto de corte de ≥2 horas/dia foi usado para categorizar o desfecho. A regressão de Poisson foi usada para avaliar associações entre o desfecho e as variáveis independentes (nível de significância de 95%) e controlar as variáveis de confusão e o possível efeito do desenho. Resultados: A amostra foi composta por 8.661 alunos. A prevalência geral de CS foi de 69,2% (IC95%: 68,1-70,2) em dias de semana e 79,6% (IC95%: 78,7-80,5) nos fins de semana. O sexo feminino mostrou maior associação com o desfecho, exceto para jogos eletrônicos. Estudantes de séries mais avançadas estavam mais envolvidos em tarefas na posição sentada, quando comparados com os das séries iniciais. Os alunos mais velhos eram mais propensos a navegar na internet por mais de duas horas por dia. Estudantes com condição econômica mais elevada eram mais propensos a passar o tempo em videogames e internet. Indivíduos ativos eram menos propensos a se envolver em CS durante a semana. Conclusões: A prevalência da CS foi elevada, principalmente nos fins de semana. As associações com sexo, idade, série escolar e nível de atividade física devem ser consideradas para elaborar intervenções mais eficientes no controle dos CS.

Physical Education classes in the Empower your Health Project: an analysis from the standpoint of Teachers / Aulas de Educação Física no Projeto Fortaleça sua Saúde: uma análise a partir da perspectiva dos Professores

The objective was to analyze the lesson plans of the Empower your Health Project (Projeto Fortaleça sua Saúde) and their applicability from the teachers' standpoint. A cross-sectional quantitative and qualitative study was conducted as part of a larger project entitled Empower Your Health. Data were collected concurrently with the implementation of the program, in the second half of 2014, at two full-time schools in the city of Fortaleza, Brazil. We analyzed 15 lesson plans applied in four elementary school classes: two 7th grade classes in school A and two 8th grade classes in school B. A semi-structured questionnaire containing seven objective questions was used to analyze aspects regarding the effectiveness of the plans. Major limitations included: students not doing their homework, not using the suggested materials and not applying the proposed activities contained in the lesson plan. It was concluded that the lesson plans exhibited limitations, but these did not compromise the objectives of the project. Thus, all classes demonstrated the potential of the plans suggested by the Empower Your Health Project for promoting a healthier lifestyle.

Objetivou-se avaliar os planos de aula do Projeto Fortaleça Sua Saúde e sua aplicabilidade na perspectiva dos professores. Trata-se de uma pesquisa de caráter transversal realizada dentro de um projeto maior intitulado: Programa Fortaleça Sua Saúde. Os dados foram coletados concomitantemente à aplicação do Programa, no segundo semestre de 2014, em duas escolas de Tempo Integral (ETI) no município de Fortaleza. Foram analisados 15 planos de aula, aplicados em quatro turmas do ensino fundamental, sendo duas turmas de 7° ano da escola na escola A e duas turmas de 8° ano na escola B. Para coleta dos dados utilizou-se um questionário semiestruturado contendo sete questões objetivas, que analisavam aspectos pertinentes a efetividade dos planos. Dentre as maiores limitações, percebeu-se: a não realização das tarefas de casa, a não utilização dos materiais sugeridos e a não aplicação das atividades propostas no plano de aula pelos professores de educação física. Conclui-se que em alguns aspectos os planos de aula apresentaram limitações, mas, que não interferiram na concretização dos objetivos do projeto. Desta forma todas as aulas demonstraram a potencialidade dos planos sugeridos pelo Projeto Fortaleça Sua Saúde para a promoção de um estilo de vida mais saudável.

RESULTS: The sample was composed by 8661 students. The overall prevalence of SB was 69.2% (CI95% 68.1-70.2) on weekdays, and 79.6% (CI95% 78.7-80.5) on weekends. Females were more associated with the outcome, except to electronic games. Advanced grades students were more involved in sitting tasks when compared to the early grades. Older students were more likely to surf on net for ≥2h/day. Higher economic level students were more likely to engage in video games and internet. Active individuals were less likely to engage in SB on weekdays. CONCLUSIONS: The prevalence of SB was high, mainly on weekends. The associations with sex, age, grade and physical activity level should be considered into elaboration of more efficient interventions on SB control.

Assessment of Central Corneal Thickness in Different Subtypes of Systemic Sclerosis.

PURPOSE: To compare central corneal thickness between patients with diffuse cutaneous systemic sclerosis and limited cutaneous systemic sclerosis. METHODS: A total of 53 consecutive patients with systemic sclerosis were enrolled in this study. All subjects were screened for age, gender, classification of disease subtype, autoantibody profile, duration of disease, organ involvement, current treatment, tear break-up time, Schirmer test, and measurement of the central corneal thickness with an ultrasonic pachymeter. RESULTS: No statistically significant differences were found in terms of age, sex, and duration of the disease, and dry eye evaluation between systemic sclerosis subsets. The mean central corneal thickness was 535.3 ± 37.6 µm (range, 471-619 µm) in diffuse cutaneous systemic sclerosis patients, and 539.3 ± 37.1 µm (range, 484-651 µm) in limited cutaneous systemic sclerosis (p = 0.71). CONCLUSIONS: Central corneal thickness in patients with diffuse cutaneous systemic sclerosis is not different from the one in limited cutaneous systemic sclerosis.
