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.

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.

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.

Dr. Harold W. (Bill) Kohl III had a significant impact on the field of physical activity and public health. His seminal works included the first study linking physical fitness to all-cause mortality and his 2012 paper in The Lancet, which emphasized the importance of addressing physical inactivity as a global public health concern. However, his most enduring legacy may be his commitment to mentorship and building capacity within the field. He created a supportive environment for his mentees, fostering collaboration and growth. He also dedicated himself to mentoring international scholars and played a crucial role in the formation and expansion of regional physical activity groups, particularly in Latin America. Dr. Kohl's mentorship was characterized by generosity, respect, high expectations, empathy, and humor. He emphasized the importance of measuring what matters and encouraged his mentees to think critically and consider the broader implications of their research. Despite his loss, his mentees are privileged to have learned from one of the best and are committed to carrying forward his legacy. [Extracted from the article]

Background: It is not always clear whether physical activity is causally related to health outcomes, or whether the associations are induced through confounding or other biases. Randomized controlled trials of physical activity are not feasible when outcomes of interest are rare or develop over many years. Thus, we need methods to improve causal inference in observational physical activity studies. Methods: We outline a range of approaches that can improve causal inference in observational physical activity research, and also discuss the impact of measurement error on results and methods to minimize this. Results: Key concepts and methods described include directed acyclic graphs, quantitative bias analysis, Mendelian randomization, and potential outcomes approaches which include propensity scores, g methods, and causal mediation. Conclusions: We provide a brief overview of some contemporary epidemiological methods that are beginning to be used in physical activity research. Adoption of these methods will help build a stronger body of evidence for the health benefits of physical activity. [ABSTRACT FROM AUTHOR]

Since 2020, the world has been navigating an epidemiologic transition with both infectious diseases (COVID-19) and noncommunicable diseases intertwined in complex and diverse ways. In fact, the pandemics of physical inactivity, noncommunicable diseases, and COVID-19 coincide in a tragically impactful ménage à trois with their detrimental long-term health consequences yet to be determined. We know that people in low- and middle-income countries not only have the highest risk of developing chronic diseases, they also develop the diseases at a younger age, they suffer longer, and they die earlier than people in high-income countries. This commentary features 5 compelling reasons for putting physical activity in low- and middle-income countries high up on the public health research agenda and calls for more commitment to inclusive and context-specific public health practices that are paired with locally relevant promotion and facilitation of PA practice, research, and policymaking.

The article presents the discussion on underlining the pandemic magnitude of physical inactivity, its health, social, environmental, and economic global consequences. Topics include COVID-19 pandemic generating more interest in the little known benefits of physical activity for infectious diseases; and reducing risk of infection, enhancing immune system function for preventing and hastening recovery from infections, and increasing effectiveness of vaccination.

The article presents the discussion on physical activity and global health quantifying the startling annual global mortality due to physical inactivity. Topics include failure for better addressing the longstanding public health crisis of physical inactivity being largely ignored; progress on physical inactivity requiring surveillance, evidence, prioritization, investment, and leadership; and multiple programmatic and policy initiatives around physical activity and obesity.

Summary: Childhood obesity is a major problem in Latin America and among US Latinos. Effective public health policies require contextually relevant evidence to guide them, which demands sustained research capacity. The objectives of this study are to determine research productivity in Latin America and in the United States focused on Latino populations and examine domains of research capacity (research infrastructure, training programs, mentoring, funding, and networks). We conducted a scoping review of indexed childhood obesity‐related articles published June 2015–December 2019. We collected data on perceptions of capacity for childhood obesity research among Latin American investigators through an online survey. We identified 612 childhood obesity‐related articles (505 from Latin America, 124 from the United States, and 17 US–Latin America collaborations). Brazil, Mexico, Chile, Colombia, and the United States are the top publishing countries. There are similar numbers of obesity, nutrition, and physical activity articles, but physical activity research capacity lagged in other domains (research training, funding, and networking opportunities). Complementary research areas, including sedentary behavior, systems science, and policy studies, are uncommon in Latin America but more prevalent in the United States, whereas sleep research is nascent across settings. Realizing the promise of an effective cross‐border collaborative childhood obesity prevention agenda will require committed investment in all domains of research capacity and across all relevant topics.

In the past few decades, the field of physical activity has grown and evolved in scope, depth, visibility and impact around the world. Global progress has been observed in research and practice in physical activity regarding surveillance, health outcomes, correlates/determinants, interventions, translation and policy. The 2012 and 2016 Lancet series on physical activity provide some of the most comprehensive global analysis on various topics within physical activity. Based on the Lancet series and other key developments in the field, literature searches, and expert group meetings and consultation, we provide a global summary on the progress of, gaps in and future directions for physical activity research in the following areas: (1) surveillance and trends, (2) correlates and determinants, (3) health outcomes and (4) interventions, programmes and policies. Besides lessons learnt within each specific area, several recommendations are shared across areas of research, including improvement in measurement, applying a global perspective with a growing emphasis on low-income and middle-income countries, improving inclusiveness and equity in research, making translation an integral part of research for real-world impact, taking an 'upstream' public health approach, and working across disciplines and sectors to co-design research and co-create solutions. We have summarised lessons learnt and recommendations for future research as 'roadmaps' in progress to encourage moving the field of physical activity towards achieving population-level impact globally.

Purpose: To describe indicators used for the assessment of antenatal care (ANC) quality worldwide under the World Health Organization (WHO) framework and based on a systematic review of the literature.Data Sources: Searches were performed in MEDLINE, SciELO, BIREME and Web of Science for eligible studies published between January 2002 and September 2016.Study Selection: Original articles describing women who had received ANC, any ANC model and, any ANC quality indicators were included.Data Extraction: Publication date, study design and ANC process indicators were extracted.Results Of Data Synthesis: Of the total studies included, 69 evaluated at least one type of ANC process indicator. According to WHO ANC guidelines, 8.7% of the articles reported healthy eating counseling and 52.2% iron and folic acid supplementation. The evaluation indicators on maternal and fetal interventions were: syphilis testing (55.1%), HIV testing (47.8%), gestational diabetes mellitus screening (40.6%) and ultrasound (27.5%). Essential ANC activities assessment ranged from 26.1% report of fetal heart sound, 50.7% of maternal weight and 63.8% of blood pressure. Regarding preventive measures recommended by WHO, tetanus vaccine was reported in 60.9% of the articles. Interventions performed by health services to improve use and quality of ANC care, promotion of maternal and fetal health, and the number of visits to the ANC were evaluated in 65.2% of the studies.Conclusion: Numerous ANC content indicators are being used to assess ANC quality. However, there is a need to use standardized indicators across countries and efforts to improve quality evaluation. [ABSTRACT FROM AUTHOR]

The article reports on the launching of the Epidemiology Council of the International Society for Physical Activity and Health (ISPAH) as of January 2020. Topics include the society's goal to raise awareness of the epidemiological approaches in physical activity research, the Physical Activity Cohort Study Repository project, and how to measure physical activity and/or sedentary behavior.

Background: Maternal physical activity (PA) during pregnancy could affect offspring's neurodevelopment. However, studies in humans in early childhood are scarce and show inconsistent results. We aimed to review the literature on the association between physical activity during pregnancy and offspring neurodevelopment.Methods: LILACS, MEDLINE and Web of Science were searched for studies published since 1977. Original studies conducted in humans, without language, country, or study type restriction, were eligible. Information on the study methodology like study design, sample size, PA exposure and neurodevelopment assessment, covariates, and the effect measure were extracted from the selected articles.Results: From 802 non-duplicated titles initially located, 6 articles were selected and included (one randomised clinical trial and 5 cohort studies). The instruments used to measure PA during pregnancy and neurodevelopment varied between the studies. PA was self-reported at different gestational ages and neurodevelopment was assessed prospectively in offspring aged 1-8 years old. Only the randomised clinical trial found no effect of PA over offspring neurodevelopment. Cohort studies found a positive association between PA practice during pregnancy and offspring neurodevelopment.Conclusions: These findings suggest that leisure-time physical activity practice may have positive association with language offspring's neurodevelopment in the age range of 18 from 60 months.

Introduction: For young adults, the first year of higher education represents a transition period into adulthood associated with an increased risk of developing depression, anxiety, and stress, contributing to deteriorating physical and mental health. The present study aimed to analyze the relationship between depressive symptoms and social capital and lifestyles among Colombian university students., Methods: In 2020, a longitudinal repeated measures study was conducted on first year students at Universidad de los Andes in Bogota, Colombia. The study was conceptualized and approved by the university before the COVID-19 pandemic appeared. Each student completed a self-administered questionnaire including questions on sociodemographic characteristics, depressive symptoms, perceived stress, social capital, and lifestyles. The study's pilot was conducted in November 2019, and the two measurement points were in January 2020 (wave 1, before the COVID-19 pandemic was declared) and in August 2020 (wave 2, during the COVID-19 pandemic). A binary logistic regression analysis was performed to assess the relationship between depressive symptoms, perceived stress, social capital, and lifestyles., Findings: A total of 609 first year students (response rate = 58.11%) participated in wave 1, and 42% of the participants showed signs of clinically relevant depressive symptoms. In wave 2, despite the difficulties encountered in collecting data due to the COVID-19 pandemic, 216 students from wave 1 participated (35.47%). An increase in a sedentary lifestyle was observed (31.49%). We found that cognitive and behavioral social capital levels decreased by 12.03 and 24.54%, respectively. In addition, we observed a 6.5% increase in students with clinically relevant depressive symptoms compared to wave 1. A low level of behavioral [ OR : 1.88; 95% CI (1.16, 3.04)] social capital was associated with clinically relevant depressive symptoms., Conclusion: The health of university students continues to be a public health concern. The study suggests that social capital may play an important role in preventing depressive symptoms. Therefore, universities should put effort into programs that bring students together and promote the creation of social capital., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Sotaquirá, Backhaus, Sotaquirá, Pinilla-Roncancio, González-Uribe, Bernal, Galeano, Mejia, La Torre, Trujillo-Maza, Suárez, Duperly and Ramirez Varela.)

About three quarters of the Malaysian adult population are physically active. There has been growth in physical activity and health research since 2010, with most studies being observational in design and few included objective measures of physical activity. The Malaysian Ministry of Health has published physical activity guidelines, strategies and action plans aimed at promoting physical activity. Physical activity promotion activities have included national campaigns and programmes which target different populations. Further work that incorporates the WHO Global Action Plans on Physical Activity (GAPPA), as well as a more systemic approach is needed, to promote physical activity and a healthy lifestyle. High-level multi-stakeholder collaboration is required for continuing expansion and strengthening of research capacity, and for bridging the physical activity policy gaps in Malaysia., (Copyright © 2020 Khoo, Poh, Suhaimi, Chong and Ramirez Varela.)
