An Overview of Physical Activity Research Evolution in Africa: The Global Observatory for Physical Activity-GoPA!

OBJECTIVE: To describe the evolution of physical activity (PA) research in Africa, examine income and gender inequalities, and discuss future possibilities. METHODS: A secondary analyses of the Global Observatory for Physical Activity data on PA research in Africa (1950-2019). RESULTS: We identified 514 PA articles from 47 African countries in the past 70 years. Majority (83.1%) of the articles were published between 2012 and 2019. Fifteen countries had no publications. Six countries (South Africa [n = 156], Nigeria [n = 85], Ethiopia [n = 44], Ghana [n = 41], Kenya [n = 39], and Cameroon [n = 20]) accounted for about 75% of the publications. Most articles were observational (92.4%), single-country studies (78.4%), with male first (58.4%) and last authors (68%), and were classified as surveillance studies (45.1%). Few studies addressed interventions (5.8%) and policy (3.5%) or used device-based PA measurement (14.0%). The number of articles per country was positively related to human population level (r = .552, P = .000) and gross domestic product % spent on research and development (r = .301, P = .040). The publication rate per 100,000 people was positively related with the human development index (r = .349, P = .016) and negatively with the gender inequality index (r = -.360, P = .019). CONCLUSIONS: Our results provide an overview and status of PA research in Africa, highlighting country differences and gender inequalities in authorship. The findings may be used to benchmark the evolution of research in the region and to inform areas for improvement. There is an urgent need for more PA interventions and policy studies in Africa.

Breaking Barriers: An Innovative Tool to Assess the National and City-Level Physical Activity Policy Development to Practice Disconnect.

BACKGROUND: Population-level physical activity increases are improbable without intersectoral collaboration across government levels and sectors to develop and implement physical activity promotion policies. This study aims to provide information about the development of the Interaction between National and Local Government Levels in Development and Implementation of Physical Activity Policies Tool (INTEGRATE PA-Pol). A framework was created to examine the development and implementation of national and subnational physical activity policies and the (mis)alignment between government levels. METHODS: The work was conducted in 3 phases: (1) a scoping review was carried out to identify local government physical activity promotion policies and instruments for assessing them, (2) an expert group designed 6 questionnaires, and (3) cognitive response testing was employed for validity testing and item modification with a panel of research and policy experts. RESULTS: The INTEGRATE PA-Pol Tool consists of 6 questionnaires assessing how national and subnational governments collaborate to develop and implement physical activity promotion policies. CONCLUSION: This tool can assist in better understanding the development and implementation of a public policy monitoring system that will allow for benchmarking and priority setting to comprehend how physical activity promotion policies are designed and executed.

Gender Differences in Physical Activity and Health-Related Authorships Between 1950 and 2019.

BACKGROUND: The objective of this study was to investigate gender differences in authorship in physical activity and health research. METHODS: A bibliometric study including 23,399 articles from 105 countries was conducted to estimate the participation of female researchers in physical activity publications from 1950 to 2019. The frequency of female researchers was analyzed and classified by first and last authors and the overall percentage of female authors by region and country. RESULTS: The proportion of female first authors increased from <10% in the 50s and 80s to 55% in the last decade. On the other hand, the proportion of last authors increased from 8.7% to 41.1% in the same period. Most publications with female researchers were from the United States, Canada, Australia, Brazil, the Netherlands, Spain, England, Germany, Sweden, and China. Nine of these countries had over 50% of the articles published by female first authors. However, in all 10 countries, <50% of the articles were published by female last authors. CONCLUSIONS: The proportion of female researchers increased over time. However, regional differences exist and should be addressed in gender equity policies. There is a gap in the participation of female researchers as last authors. By actively addressing the gender gap in research, the global society can harness the full potential of all talented individuals, regardless of gender, leading to more inclusive and impactful scientific advancements.

The Evolution of Physical Activity and Health Research in China: A Bibliometric Analysis of Study Areas and Sex Balance in Authorship.

BACKGROUND: This article evaluates the evolution of physical activity and health research in China through a bibliometric analysis focused on number of publications, study areas, and sex balance in authorship. METHODS: A systematic review was conducted by the Global Observatory for Physical Activity for "physical activity and health" publications between 1950 and 2019. Here, we focus on the 610 Chinese publications identified, defined as those in which data collection took place in China. We assessed the number of publications, classified them into 5 areas (1) surveillance, (2) correlates and determinants, (3) health consequences, (4) interventions, and (5) policy, and analyzed female participation in authorship. RESULTS: The first Chinese publication identified in the review was in 1990. Since, the average number of physical activity and health publications increased from one per year in the 1990s to 7.6 per year in the 2000s, and to 47 per year in the 2010s. Most publications focused on the correlates and determinants (38.7%) and the health consequences of physical activity (35.9%). Physical activity policy accounted for 2.3% of the publications. In the 1990s, 64% of the publications included at least one female author; this proportion increased to 90% in the 2010s. CONCLUSION: Despite a slow start, China's research on physical activity and health has grown rapidly since 2000. The distribution of publications by study areas and female participation in authorship is similar to that observed globally, with fewer publications focused on interventions and policy as compared with other topics.

Self-perception of mental health, COVID-19 and associated sociodemographic-contextual factors in Latin America.

This study aimed to estimate the prevalence of alterations in self-perceived mental health during the COVID-19 pandemic and their associated factors in four Latin American countries. This is a cross-sectional study based on data collected from adults in 2021 through the Collaborative Response COVID-19 Survey by the MacDonnell Academy at Washington University in St. Louis (United States). The sample was composed of 8,125 individuals from Brazil, Colombia, Mexico, and Chile. A generalized linear model for a binary outcome variable with a logistic link and fixed country effects was used. There were 2,336 (28.75%) individuals who considered having suffered alterations in self-perceived mental health. Unemployed individuals (OR = 1.40; 95%CI: 1.24-1.58), those with bad/regular quality of life (OR = 5.03; 95%CI: 4.01-6.31), and those with high socioeconomic status (OR = 1.66; 95%CI: 1.41-1.96) had a higher risk of self-perceived mental health alterations than those with full-time employment, excellent quality, and low socioeconomic status. According to the fixed-effects model, Brazilians living in the country during the pandemic, who disagreed with their government's decisions (OR = 2.05; 95%CI: 1.74-2.42) and lacked trust in their government (OR = 2.10; 95%CI: 1.74-2.42) had a higher risk of having self-perceived mental health alterations. Nearly 30% of respondents indicated that the COVID-19 pandemic altered their self-perceived mental health. This outcome was associated with political, sociodemographic, and health risk factors. These findings should help policymakers develop post-pandemic community interventions.

Severity and mortality of acute respiratory failure in pediatrics: A prospective multicenter cohort in Bogotá, Colombia.

Background and Aims: Acute respiratory failure (ARF) is the most frequent cause of cardiorespiratory arrest and subsequent death in children worldwide. There have been limited studies regarding ARF in high altitude settings. The aim of this study was to calculate mortality and describe associated factors for severity and mortality in children with ARF. Methods: The study was conducted within a prospective multicentric cohort that evaluated the natural history of pediatric ARF. For this analysis three primary outcomes were studied: mortality, invasive mechanical ventilation, and pediatric intensive care unit (PICU) length of stay. Eligible patients were children older than 1 month and younger than 18 years of age with respiratory difficulty at the time of admission. Patients who developed ARF were followed at the time of ARF, 48 h later, at the time of discharge, and at 30 and 60 days after discharge. It was conducted in the pediatric emergency, in-hospital, and critical-care services in three hospitals in Bogotá, Colombia, from April 2020 to June 2021. Results: Out of a total of 685 eligible patients, 296 developed ARF for a calculated incidence of ARF of 43.2%. Of the ARF group, 90 patients (30.4%) needed orotracheal intubation, for a mean of 9.57 days of ventilation (interquartile range = 3.00-11.5). Incidence of mortality was 6.1% (n = 18). The associated factors for mortality in ARF were a history of a neurologic comorbidity and a higher fraction of inspired oxygen at ARF diagnosis. For PICU length of stay, the associated factors were age between 2 and 5 years of age, exposure to smokers, and respiratory comorbidity. Finally, for mechanical ventilation, the risk factors were obesity and being unstable at admission. Conclusions: ARF is a common cause of morbidity and mortality in children. Understanding the factors associated with greater mortality and severity of ARF might allow earlier recognition and initiation of prompt treatment strategies.

Resumen Este estudio tuvo como objetivo estimar la prevalencia de alteraciones en la autopercepción de la salud mental durante la pandemia de COVID-19 y sus factores asociados en cuatro países de América Latina. Este es un estudio transversal de datos recopilados de adultos en el 2021 por medio de la investigación Respuesta Colaborativa a COVID-19 de la Academia McDonnell en la Universidad Washington en St. Louis (Estados Unidos). La muestra estuvo compuesta por 8.125 personas de Brasil, Colombia, México y Chile. El estudio utilizó un modelo lineal generalizado para una variable de desenlace binario con un enlace logístico y efectos fijos por país. En total, 2.336 (28,75%) personas consideraron que habían sufrido alteraciones en la autopercepción de la salud mental. Los desempleados (OR = 1,40; IC95%: 1,24-1,58), aquellos con calidad de vida mala/regular (OR = 5,03; IC95%: 4,01-6,31) y aquellos con alto nivel socioeconómico (OR = 1,66; IC95%: 1,41-1,96) presentaron mayor riesgo de alteraciones en la autopercepción de la salud mental que aquellos con empleo a tiempo completo, excelente calidad y bajo nivel socioeconómico. Según el modelo de efectos fijos, los brasileños que vivían en el país durante la pandemia y que no estuvieron de acuerdo con las decisiones del gobierno (OR = 2,05; IC95%: 1,74-2,42) y no confiaban en su gobierno (OR = 2,10; IC95%: 1,74-2,42) presentaron mayor riesgo de alteraciones en la autopercepción de la salud mental. Casi el 30% de los encuestados indicaron que la pandemia de COVID-19 alteró su autopercepción de la salud mental. Este desenlace se asoció con factores políticos, sociodemográficos y de riesgo a la salud. Estos hallazgos deben ayudar a los formuladores de políticas a desarrollar intervenciones comunitarias pospandémicas.

Resumo Este estudo teve como objetivo estimar a prevalência de alterações na autopercepção de saúde mental durante a pandemia de COVID-19 e seus fatores associados em quatro países da América Latina. Este é um estudo transversal de dados coletados de adultos em 2021 por meio da pesquisa Resposta Colaborativa à COVID-19 da Academia McDonnell na Universidade Washington em St. Louis (Estados Unidos). A amostra foi composta por 8.125 pessoas do Brasil, Colômbia, México e Chile. O estudo utilizou um modelo linear generalizado para uma variável de desfecho binário com uma conexão logística e efeitos fixos do país. No total, 2.336 (28,75%) pessoas consideraram ter sofrido alterações na autopercepção de saúde mental. Os desempregados (OR = 1,40; IC95%: 1,24-1,58), aqueles com qualidade de vida ruim/regular (OR = 5,03; IC95%: 4,01-6,31) e aqueles com alto nível socioeconômico (OR = 1,66; IC95%: 1,41-1,96) apresentaram maior risco de alterações na autopercepção de saúde mental do que aqueles com emprego em tempo integral, excelente qualidade e baixo nível socioeconômico. De acordo com o modelo de efeitos fixos, os brasileiros que viviam no país durante a pandemia, que discordavam das decisões do governo (OR = 2,05; IC95%: 1,74-2,42) e não confiavam em seu governo (OR = 2,10; IC95%: 1,74-2,42) apresentaram maior risco de alterações na autopercepção de saúde mental. Quase 30% dos entrevistados indicaram que a pandemia da COVID-19 alterou sua autopercepção de saúde mental. Esse desfecho estava associado a fatores políticos, sociodemográficos e de risco à saúde. Estes achados devem ajudar os formuladores de políticas a desenvolver intervenções comunitárias pós-pandemia.

Worldwide evidence about infant stunting from a public health perspective: A systematic review / Evidencia mundial sobre el retraso del crecimiento infantil desde una perspectiva de salud pública: revisión sistemática

Abstract Introduction: According to the World Health Organization (WHO) global estimates for 2017, 9.6% of children under 5 years old are stunted. Worldwide evidence shows that actions for preventing stunting and catching-up growth are relevant if addressed by all the sectors involved. Therefore, there is a need to identify 'intersectoral actions' to address the risk of stunting during pregnancy and the first 2 years of life. Objective: To identify and describe worldwide evidence for prevention, nutritional interventions, and 'intersectoral collaboration' efforts against stunting in infants. Materials and methods: We conducted a systematic review in 2019 (PROSPERO CRD42019134431). The search included PubMed, OVID, and Web of Science, as well as WHO and the Food and Agriculture Organization of the United Nations (FAO) official documents and expert recommendations. Results: We selected 231 studies: 86.1% described prevention-related factors, 30.7%, nutritional interventions, and 52.8% intersectoral collaboration efforts; 36.4% of the studies were conducted in multiple regions; 61% of the studies described the importance of interventions during pregnancy, 71.9% from birth up to 6 months old, and 84.8% from 6 months up to 2 years old. The most frequent variables described were antenatal care, nutritional counseling for the mother and the newborn, and counseling on micronutrient supplementation. Conclusions: Evidence-based understanding of actions geared towards monitoring the risk of stunting-associated factors from pregnancy up to 2 years old is critical.

Resumen Introducción. Según estimaciones mundiales de la Organización Mundial de la Salud (OMS) para el 2017, el 9,6 % de los niños menores de cinco años padecen retraso del crecimiento. La evidencia mundial ha demostrado que las acciones para prevenir el retardo del crecimiento o para tratarlo adquieren relevancia si las abordan todos los sectores involucrados. Por lo tanto, es necesario determinar las acciones intersectoriales para atender el riesgo de retraso del crecimiento durante el embarazo y los dos primeros años de vida. Objetivo. Rastrear y describir la evidencia mundial para la prevención, las intervenciones nutricionales y los esfuerzos de colaboración intersectorial contra el retraso del crecimiento en los lactantes. Materiales y métodos: Se hizo una revisión sistemática en el 2019 (PROSPERO CRD42019134431). La búsqueda incluyó PubMed, OVID y Web of Science, así como documentos oficiales de la OMS y la Organización para la Agricultura y la Alimentación de Naciones Unidas (FAO) y recomendaciones de expertos. Resultados. Se seleccionó un total de 231 estudios: 86,1 % describían factores relacionados con la prevención, 30,7 %, intervenciones nutricionales, y 52,8 %, esfuerzos de colaboración intersectorial; 36,4 % de ellos se llevaron a cabo en múltiples regiones. Del total, el 61 % de los estudios se enfocaba en la importancia de las intervenciones durante el embarazo, el 71,9 % desde el nacimiento hasta los seis meses y el 84,8 % desde los seis meses hasta los dos años. Las variables descritas con mayor frecuencia fueron la atención prenatal, el asesoramiento nutricional para la madre y el recién nacido, y el asesoramiento sobre la suplementación con micronutrientes. Conclusiones. La comprensión basada en la evidencia de las acciones orientadas a monitorear el riesgo de factores asociados al retraso del crecimiento desde el embarazo hasta los dos años, es fundamental.

Health risk behavior of Brazilian university men

The insertion of men in the university environment is a complex and worrying phenomenon permeated by vulnerabilities, which are associated with the adoption of risky behaviors for health. The objective of this study was to evaluate the health behavior of Brazilian university men. A cross-sectional study with 663 men students. The study used a questionnaire on health-related life habits. All the questions were extracted from the Surveillance of Risk and Protection Factors for Chronic Diseases through Telephone Interviews. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals and chi-square tests. The analysis of the joint relationships between nutritional status, physical activity and diet was conducted by the multiple correspondence analysis. Of the 663 students, 67.8% were between 20-29 years of age, 69.2% consumed alcohol, 34.5% did not do physical activity, and 34.2% were overweight. The students who did not engage in physical activity smoked more (p=0.05), consumed less fruit (p<0.01), less salad (p<0.01), and consumed full fat milk (p=0.05). In the physically inactive students, a high prevalence of acquiring diabetes mellitus (p<0.01) and high cholesterol (p<0.01) was observed. University students were found to have unhealthy lifestyles. More public policies aimed at promoting preventive measures at universities are needed to encourage healthier health behaviors(AU)

La inserción de los varones en el ámbito universitario es un fenómeno complejo y preocupante permeado por vulnerabilidades, las cuales están asociadas a la adopción de conductas de riesgo para la salud. El objetivo del trabajo fue evaluar el comportamiento de salud de los varones universitarios brasileños. Estudio transversal con 663 varones. El estudio utilizó un cuestionario sobre hábitos de vida relacionados con la salud. Todas las preguntas fueron extraídas de la Vigilancia de Factores de Riesgo y Protección de Enfermedades Crónicas mediante entrevistas telefónicas (Vigitel). Se utilizó la regresión logística para estimar los odds ratios (OR) y los intervalos de confianza del 95% and pruebas del test chi-cuadrado. El análisis de las relaciones conjuntas entre estado nutricional, actividad física y dieta se realizó mediante el análisis de correspondencias múltiples. De los 663 varones, el 67,8% tenía entre 20 y 29 años, el 69,2% consumía alcohol, el 34,5% no hacía actividad física y el 34,2% tenía sobrepeso. Los varones que no realizaron actividad física fumaron más (p = 0,05), consumieron menos fruta (p<0,01), menos ensalada (p<0,01) y consumieron leche entera (p = 0,05). En los varones físicamente inactivos, se observó una alta prevalencia de diabetes mellitus (p<0,01) y colesterol alto (p<0,01). Se descubrió que los varones universitarios tenían estilos de vida poco saludables. Se necesitan más políticas públicas orientadas a promover medidas preventivas en las universidades para fomentar comportamientos de salud más saludables(AU)

COVID-19 and public transport: an overview and recommendations applicable to Latin America / COVID-19 y transporte público: una revisión y recomendaciones aplicables a América Latina

Abstract The article presents a general overview on COVID-19 transmission in the context of public transport, particularly applicable to decision making in Latin America. Based on recent findings on COVID-19 transmission and the relative importance of each factor (droplets, fomites, and aerosol routes) in such transmission, we seek to update the discussion on the topic that has generally been based on social distance as the only parameter for reducing the risk of transmission and broadens the vision to integrate ventilation, users' behavior (mask and eye protection use, silence while in the transport system) and travel distance. Recommendations to improve mobility conditions reducing the risk of COVID-19 contagion are provided.

Resumen El artículo presenta una revisión de transmisión de COVID-19 en el contexto de transporte público, con aplicación particular para toma de decisiones en América Latina. Con base en los hallazgos recientes sobre transmisión de Covid-19 y la importancia relativa de cada factor (gotículas, fómites y rutas de aerosoles) en dicha transmisión, buscamos actualizar la discusión sobre el tema que generalmente se ha basado en la "distancia social" como parámetro único de reducción de riesgo de transmisión y amplía esta visión para integrar la ventilación, el comportamiento de usuarios (uso de mascarilla, protección ocular, silencio), y la distancia de viaje. Se indican al final recomendaciones para mejorar las condiciones de movilidad en general sin aumentar el riesgo de contagio de Covid-19.

Objetivo: Verificar a prevalência do consumo de álcool e tabaco entre acadêmicos. Métodos: Estudo de corte transversal, realizado com 286 acadêmicos do Distrito Federal, no período de agosto a outubro de 2016, no qual se aplicou questionário estruturado de autopreenchimento sobre idade, sexo, tipo de escola no ensino médio, nível socioeconômico, local de moradia, frequência de uso do álcool e tabaco, e autopercepção de saúde. Dados analisados através dos testes qui-quadrado e regressões logísticas, com nível de significância de 5%. Resultados: Dos 286 acadêmicos, 190 (66,4%) consomem álcool e 14 (5%) fumam em festas ou no fim de semana. Entre eles, 132 (94,3%) mulheres e 46 (92%) homens relataram que este hábito foi adquirido antes de ingressar na instituição de ensino. Os que moram com os pais ou parentes apresentaram maior prevalência de tabagismo 25,4% [OR 1,27; IC95% 0,40-4,03]. e os que moram sozinhos um maior consumo de álcool 70,3% [OR 1,09;IC95% 0,30-3,91]. Quanto menor a autopercepção de saúde, maior a probabilidade de consumo de álcool (83,3%) [OR 2,25; IC95% 0,25-19,9]. Conclusão: A prevalência do consumo de álcool entre os acadêmicos investigados é elevada, e a sua frequência é maior entre o sexo feminino. Quanto ao uso de tabaco, notou-se baixa prevalência entre todos os participantes.

Objective: To assess the prevalence of alcohol and tobacco use among university students. Methods: Cross-sectional study carried out with 286 university students from the Federal District from August to October 2016 using a structured self-administered questionnaire on age, gender, type of high school, socioeconomic status, place of residence, frequency of alcohol and tobacco use, and self-perception of health. Data were analyzed using chi-squared tests and logistic regressions with a significance level of 5%. Results: Of the 286 students, 190 (66.4%) use alcohol and 14 (5%) smoke at parties or on the weekend. In all, 132 (94.3%) women and 46 (92%) men said these habits started before university admission. Those who live with their parents or relatives had a higher prevalence of smoking 25.4% [OR 1.27; 95%CI 0.40-4.03] and those who lived alone presented higher alcohol consumption 70.3% [OR 1.09; 95%CI 0.30-3.91]. The poorer the self-perception of health, the higher the probability of alcohol consumption (83.3%) [OR 2.25; 95%CI 0.25-19.9]. Conclusion: The prevalence of alcohol consumption among the analyzed students is high, with higher rates among women. As for tobacco use, there was a low prevalence among the students.
