RESUMO
Civic engagement during emerging adulthood plays a pivotal role in fostering a sense of community responsibility, providing a sense of societal purpose, and contributes to improved psychological adjustment. In this mixed-method longitudinal study, we further explored how civic engagement and psychological adjustment codevelop across emerging adulthood. Participants were drawn from The Future's Study, a Canadian longitudinal study capturing the transition to adulthood in Southwestern Ontario. The sample was predominantly White (81%), female identifying (71%), and largely affluent with 5.8% reporting lower than average family income. At ages 23, 26, and 32, participants completed measures of civic engagement, depression, and optimism; at age 26, participants had the opportunity to also complete a life story interview where they were asked to recount a key community scene from their lives and reflect on its impact. Random intercept cross-lagged panel models illustrated that civic engagement across ages 23-32 reduced loneliness concurrently and longitudinally. No cross-lagged associations were found for depression or optimism. Four themes illuminated the role of civic engagement in buffering against loneliness during emerging adulthood and into midlife: community unites people through a shared vision, fosters meaningful and long-lasting connections, solidifies the importance of leaving a legacy for future generations, and contributes to personal growth via insight into others' lives, which illuminated an awareness of one's own social advantages and privilege. These results illustrate that the pathway between increased civic engagement and reduced loneliness may be due, in part, to intrinsic and collective motives that tie together personal growth, identity, and generativity.

RESUMO
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.

To understand the environmental determinants of physical activity (PA), precise spatial localization is crucial. This cross-sectional study focuses on the spatiotemporal distribution of PA among Czech adolescents (n = 171) using Global Positioning System loggers and accelerometers. The results showed that adolescents spent most of their time in sedentary behavior, with 57.2% and 58.5% of monitored time at home and school, respectively. The park and playground had the lowest proportion of sedentary behavior but also the lowest amount of moderate to vigorous PA (MVPA). However, when considering the time spent in each domain, the highest proportion of MVPA was seen in publicly accessible playgrounds (13.3% of the time). Chi-square analysis showed that the relative distribution of different PA intensities did not differ across spatial domains. Based on these results, the authors propose 2 key strategies for increasing MVPA in adolescents: Increase the time spent in activity-supportive environments, such as parks and playgrounds, and design techniques to increase MVPA at home and school settings.

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.

BACKGROUND: National physical activity (PA) policy processes are only beginning to be studied in Latin America, and little attention has focused at the subnational level. This study examined national-subnational relations in the policy process (agenda setting, policy formulation, adoption, implementation, and evaluation) in selected Latin American countries. METHODS: The Global Observatory for Physical Activity's (GoPA!) INTEGRATE-PA-Pol tool was applied in Colombia, Costa Rica, Ecuador, and Mexico. Data were collected in matched pairs of the capital plus one noncapital city among national and subnational policymakers (n = 27), previously identified by the GoPA! Country Contacts. PA policy development and implementation were assessed using descriptive statistics. RESULTS: Twenty-three (response rate = 85.2%) informants provided data, mainly from the health sector (52.2%), followed by the sport (26.1%), transport (13.0%), and education (8.7%) sectors. Most informants reported that their countries had a current PA policy embedded within noncommunicable diseases prevention plans (46.2%), other plans (46.2%), or obesity prevention/management/control plans (7.7%). Respondents at the subnational level rated PA promotion as central (64.3%), while the national-level role was important but not central (75.0%). National and subnational policymakers indicated low-to-little involvement in the other level's PA policy processes across the 5 policy stages. CONCLUSIONS: This study demonstrated that collecting national and subnational PA policy data across countries with the active collaboration of the GoPA! network was feasible. We also successfully identified governmental interactions throughout the PA policy process, suggesting suboptimal engagement between national and subnational levels.

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: 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.

Most adolescents do not meet physical activity guidelines, so understanding facilitators and barriers is important. This study used surveys and geocoded location data to examine associations of availability of parks and recreation facilities with adolescent-reported participation in organized team sports and physical activity classes. The study was conducted with 928 adolescents aged 12-17 years, plus one parent/caretaker, recruited from two regions of the US. Adolescents' participation in teams and classes was positively associated with parents' perceptions of multiple available recreation environments, but not with objectively-measured availability. Having multiple nearby parks and recreation facilities may provide adolescents with more options for participating in preferred organized team sports and activity classes.
RESUMO
BACKGROUND: A significant gap remains between the availability of physical activity (PA) evidence-based interventions and their application in real-world settings in policy and practice areas. This study aims to describe highly cited and high altmetrics publications in PA research and explore their impact on PA policy and practice. METHODS: Mixed-methods sequential explanatory study including the identification and description of the top highly cited and high altmetrics PA publications from the last 10 years (including study design, population, type of PA study, number of citations, and altmetrics score), and interviews with key informants regarding research dissemination and implications on PA policy and practice. RESULTS: When considering publication type, the most frequent highly cited publications were health consequences (40%, altmetrics = 42%), measurement/trends (23%, altmetrics = 10%), and correlates/determinants (21%, altmetrics = 26%) studies. They were predominantly cross-sectional (50%, altmetrics = 28%), systematic reviews (38%, altmetrics = 18%), and longitudinal studies (8%, altmetrics = 37%). All authors who participated in the interviews agreed that the most important factors in disseminating findings and influencing PA policy and practice were the published peer-reviewed manuscript itself, the reputation of the journal, the communication strategy, and the use of online platforms. CONCLUSIONS: To have a real-world influence on PA policy and practice, it is not enough to publish the results in scientific journals and participate in media outreach. To successfully involve policymakers and communities in appropriating the evidence and evaluating the extent to which these findings affect policy and practice outcomes, it is critical to lead co-creation, co-dissemination, advocacy, and capacity building efforts.

BACKGROUND: Nearly half of American adults fail to meet national guidelines for physical activity (PA). As a major contributor to the development of preventable chronic diseases, insufficient PA is an important target for health behaviour interventions. Exercise is Medicine (EIM) aims to increase PA levels among primary care patients through routine PA evaluation, prescription, brief counselling, and referral to community resources. PA is treated as a vital sign with the goal of increasing PA levels in prescribed manageable doses. EIM is currently being implemented in UC San Diego Health System's primary care clinics. OBJECTIVE: (i) To collect and summarize patient perceptions of EIM and its components. (ii) To identify discrepancies between patient-reported feedback and primary care provider (PCP) documentation in corresponding visit notes in the electronic medical record (EMR). METHODS: Patient recall of EIM components was measured using a 10-item survey distributed via MyChart. PCP documentation of EIM was tracked in the EMR system. RESULTS: Patient feedback (n = 316) about EIM components was positive and reinforced patients' confidence in their ability to increase PA. Approximately 70% of patients reported having a PA discussion with their PCP at their most recent visit, but only approximately 21% of these discussions were documented by PCPs using the preprogrammed smartphrase in the EMR. CONCLUSION: Overall, patients reported positive perceptions of EIM. While patient perceptions of EIM suggested that PA discussions with PCPs are happening during the majority of visits, PCP documentation fell behind. Documentation via smartphrase may need to be modified for physicians to use.
The Exercise is Medicine (EIM) program encourages primary care patients to increase their weekly physical activity (PA). The program includes an initial PA evaluation, prescription, counselling, and referral to community resources. EIM is currently active at UC San Diego Health System's primary care clinics. In this study, patient feedback of program components is collected and physician documentation in the electronic medical records system is evaluated. Overall, feedback was positive with patients reporting high levels of self-confidence in their ability to increase their weekly PA. Patients indicated that PA was discussed at roughly 70% of all recent visits. However, physician documentation indicated that PA was discussed at approximately 21% of all recent visits. Although PA was successfully addressed, documentation may need to be modified to more accurately reflect EIM program usage.

INTRODUCTION: Attributes of the neighborhood-built environment are associated with self-reported physical activity, but only a few studies have concentrated on device-measured physical activity in Latin America. This study examines the associations of perceived neighborhood-built environment attributes, device-measured sedentary time, and light-intensity and moderate-to-vigorous physical activity in adults from 8 Latin American countries. METHODS: Data from Estudio Latinoamericano de Nutrición y Salud adult study, an observational multicountry study (N=2,478), were analyzed in 2020. Data were collected between 2014 and 2015. Perceived neighborhood-built environment attributes were measured using the Neighbourhood Environment Walkability Survey. Sedentary time, light-intensity physical activity, and moderate-to-vigorous physical activity data were collected using accelerometers. RESULTS: No associations between perceived neighborhood-built environment attributes and sedentary time were found. Positive perceptions of walking/cycling facilities (ß=6.50, 95% CI=2.12, 10.39) were associated with more light-intensity physical activity. Perceptions of better aesthetics (Argentina) and better walking/cycling facilities (Brazil and Ecuador) were positively associated with light-intensity physical activity. Land use mix-diversity (ß=0.14, 95% CI=0.03, 0.25), walking/cycling facilities (ß=0.16, 95% CI=0.05, 0.27), aesthetics (ß=0.16, 95% CI=0.02, 0.30), and safety from traffic (ß=0.18, 95% CI=0.05, 0.24) were positively associated with moderate-to-vigorous physical activity. Land use mix-diversity, street connectivity, and safety from traffic were positively associated with moderate-to-vigorous physical activity in Venezuela. CONCLUSIONS: These findings have implications for policy recommendations, which can guide policies to promote physical activity in the region. Land use mix-diversity, walking/cycling facilities, aesthetics, and safety from traffic can maintain or increase the levels of light-intensity and moderate-to-vigorous physical activity among Latin American adults.

Helping behaviors (e.g., helping a sick friend, volunteering) are important forms of community involvement and likely change with age and life context. Yet, trajectories of community helping from adolescence through early adulthood have rarely been examined. It is also unclear how the roles of family, friends, and social attitudes might foster the development of helping behaviors across these years. We report on a study of community helping in a Canadian youth sample, across five intervals over a 15-year span, beginning at age 17 (N = 416). Helping displayed a quadratic trend, decreasing into the mid-20s, and then rebounding somewhat by 32. Social responsibility and salience of friends' prosocial moral values positively predicted age 17 community helping, whereas parents' moral values predicted less decrease in helping over this timeline. These findings add to an understanding of moral influences and social responsibility, in the potential shaping of youths' community helping behaviors.

This longitudinal follow-up studied continued effects of parental influences on narrative identity in young adulthood. Decades of research have shown the importance of parental shared reminiscing and positive parenting for the development of children's and youths' autobiographical memory and narrative identity. Yet, research on long-term influences of parenting on narrative indices in adulthood is scarce, even though parents' traces remain a part of narrative identity throughout the life span (Köber & Habermas, 2018). Therefore, in this study, 118 individuals (at time 1: Mage = 17.3 years, SD = .77, 73% female, 82% White) reported at age 17 on their perceived positive parenting. As emerging and young adults, as part of follow-ups at ages 26 and again at 32, participants provided life story interviews. First, it was tested whether earlier positive parenting longitudinally predicted parents' traces in later life stories. Second, we studied the joint long-term prediction of parenting and parents' traces to several narrative features of these young adults' life stories, including emotional tone, coherent positive resolution, and narrative complexity. Results replicated prior research on parents' traces and showed moreover that perceived parenting shape offspring's narrative identity well into young adulthood. These long-term findings are consistent with the notion that narrative identity in adulthood is rooted in the family, and continuously shaped by experiences with parents.

Meiotic arrest is a common cause of human male infertility, but the causes of this arrest are poorly understood. Transactive response DNA-binding protein of 43 kDa (TDP-43) is highly expressed in spermatocytes in the preleptotene and pachytene stages of meiosis. TDP-43 is linked to several human neurodegenerative disorders wherein its nuclear clearance accompanied by cytoplasmic aggregates underlies neurodegeneration. Exploring the functional requirement for TDP-43 for spermatogenesis for the first time, we show here that conditional KO (cKO) of the Tardbp gene (encoding TDP-43) in male germ cells of mice leads to reduced testis size, depletion of germ cells, vacuole formation within the seminiferous epithelium, and reduced sperm production. Fertility trials also indicated severe subfertility. Spermatocytes of cKO mice showed failure to complete prophase I of meiosis with arrest at the midpachytene stage. Staining of synaptonemal complex protein 3 and γH2AX, markers of the meiotic synaptonemal complex and DNA damage, respectively, and super illumination microscopy revealed nonhomologous pairing and synapsis defects. Quantitative RT-PCR showed reduction in the expression of genes critical for prophase I of meiosis, including Spo11 (initiator of meiotic double-stranded breaks), Rec8 (meiotic recombination protein), and Rad21L (RAD21-like, cohesin complex component), as well as those involved in the retinoic acid pathway critical for entry into meiosis. RNA-Seq showed 1036 upregulated and 1638 downregulated genes (false discovery rate <0.05) in the Tardbp cKO testis, impacting meiosis pathways. Our work reveals a crucial role for TDP-43 in male meiosis and suggests that some forms of meiotic arrest seen in infertile men may result from the loss of function of TDP-43.

La obesidad infantil es un problema grave en Latinoamérica y entre la población latina de EE. UU. Para ser eficaces, las políticas de salud pública tienen que estar guiadas por evidencias contextuales pertinentes, lo cual exige una capacidad de investigación sostenida a través del tiempo. Los objetivos de este estudio son determinar la productividad de la investigación enfocada en las poblaciones latinas en Latinoamérica y Estados Unidos, y examinar los dominios de la capacidad de investigación (infraestructuras, programas de formación, mentoría, financiamiento y redes de contactos). Realizamos una revisión exploratoria de artículos indexados relacionados con la obesidad infantil publicados entre junio de 2015 y diciembre de 2019. Recabamos información sobre las percepciones de los investigadores latinoamericanos respecto a la capacidad de investigación en obesidad infantil a través de una encuesta en línea. Identificamos 612 artículos relacionados con la obesidad infantil (505 de Latinoamérica, 124 de EE. UU. y 17 de colaboraciones entre EE. UU. y Latinoamérica). Brasil, México, Chile, Colombia y Estados Unidos son los países con más publicaciones. Encontramos aproximadamente el mismo número de artículos sobre obesidad, nutrición y actividad física; sin embargo, observamos que la capacidad de investigación sobre actividad física está rezagada en otros dominios (formación en investigación, financiamiento y oportunidades para establecer contactos). Otras áreas de investigación complementarias, como el comportamiento sedentario, la ciencia de sistemas y los estudios de políticas, son poco frecuentes en Latinoamérica, pero más habituales en Estados Unidos, mientras que la investigación sobre el sueño es incipiente en ambas regiones. Para cumplir la promesa de crear un programa eficaz de colaboración transfronteriza para la prevención de la obesidad infantil será necesario invertir en todos los dominios de la capacidad de investigación y en todos los temas pertinentes.

INTRODUCTION: The pedestrian hybrid beacon (PHB) is a traffic control device used at pedestrian crossings. A recent Arizona Department of Transportation research effort investigated changes in crashes for different severity levels and crash types (e.g., rear-end crashes) due to the PHB presence, as well as for crashes involving pedestrians and bicycles. METHOD: Two types of methodologies were used to evaluate the safety of PHBs: (a) an Empirical Bayes (EB) before-after study, and (b) a long-term cross-sectional observational study. For the EB before-after evaluation, the research team considered three reference groups: unsignalized intersections, signalized intersections, and both unsignalized and signalized intersections combined. RESULTS: For the signalized and combined unsignalized and signalized intersection groups, all crash types considered showed statistically significant reductions in crashes (e.g., total crashes, fatal and injury crashes, rear-end crashes, fatal and injury rear-end crashes, angle crashes, fatal and injury angle crashes, pedestrian-related crashes, and fatal and injury pedestrian-related crashes). A cross-sectional study was conducted with a larger number of PHBs (186) to identify relationships between roadway characteristics and crashes at PHBs, especially with respect to the distance to an adjacent traffic control signal. The distance to an adjacent traffic signal was found to be significant only at the αâ¯=â¯0.1 level, and only for rear-end and fatal and injury rear-end crashes. CONCLUSIONS: This analysis represents the largest known study to date on the safety impacts of PHBs, along with a focus on how crossing and geometric characteristics affect crash patterns. The study showed the safety benefits of PHBs for both pedestrians and vehicles. Practical Applications: The findings from this study clearly support the installation of PHBs at midblock or intersection crossings, as well as at crossings on higher-speed roads.
