    The purpose of this paper is to explore the construction of the professional identity of Alex (a pseudonym), a physical educator in charge of sport and physical activity in a Spanish prison. To this end, we used a biographical-dialectic perspective based mainly on interviews especially focused on prior experiences, contextual resources and the micropolitical strategies Alex used in his workplace. The search for better job conditions and professional recognition mediated the strategies he used during the daily negotiation of his professional identity. Yet, this identity was also constructed in a dialogue between his experiences in sport and the performance discourse present at the macro-social level. This study exemplifies a particular, yet not unique case of professional socialization that helps illuminate the (re)construction of identity of those physical activity and sport professionals who work in marginal contexts

    El objetivo de este artículo fue explorar el significado que las diferentes prácticas físicas realizadas en prisión adquirían para las mujeres con respecto a las relaciones interpersonales, y asociarlo con la fase de construcción de su nueva identidad desarrollada durante el encarcelamiento. A partir de una investigación cualitativa donde se entrevistó a 16 mujeres de entre 23 y 62 años que participaron en actividades físico-deportivas dentro del centro penitenciario, los resultados señalaron que dichas actividades constituyeron una vía de resocialización para las mujeres encarceladas. Este aumento de relaciones interpersonales influyó en su (re)categorización, reforzando considerablemente su pertenencia a un nuevo grupo que buscaba a través de las prácticas físicas alejarse de las adicciones propias del medio carcelario y construir una nueva identidad positiva que generase un aumento en su bienestar psico-sociológico.The aim of this article was to explore how different physical activities assisted in the development of interpersonal relationships and the self-construction of new identities for a group of women prisoners during their period of incarceration. Using qualitative research, sixteen women between the ages of 23 and 62 were interviewed, all of whom had participated in sport and physical activities within the prison. It was found that those activities constituted a new way of socialising for imprisoned women. Such increase of interpersonal relationship influenced participants' (re)categorization, reinforcing considerably their belongness into a new group who attempted, through physical practices, to move away from addictions associated with the prison environment and build up a new positive identity that would improve their psycho-social well-being.O objetivo deste artigo foi explorar o significado que diferentes práticas físicas na prisão adquiriram para as mulheres em relação às relações interpessoais, e associá-la à fase de construção de sua nova identidade desenvolvida durante o encarceramento.

    Summary Background Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. Methods For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease Risk Factor Collaboration. We applied a Bayesian hierarchical model to estimate trends from 1985 to 2019 in mean height and mean BMI in 1-year age groups for ages 5–19 years. The model allowed for non-linear changes over time in mean height and mean BMI and for non-linear changes with age of children and adolescents, including periods of rapid growth during adolescence. Findings We pooled data from 2181 population-based studies, with measurements of height and weight in 65 million participants in 200 countries and territories. In 2019, we estimated a difference of 20 cm or higher in mean height of 19-year-old adolescents between countries with the tallest populations (the Netherlands, Montenegro, Estonia, and Bosnia and Herzegovina for boys; and the Netherlands, Montenegro, Denmark, and Iceland for girls) and those with the shortest populations (Timor-Leste, Laos, Solomon Islands, and Papua New Guinea for boys; and Guatemala, Bangladesh, Nepal, and Timor-Leste for girls). In the same year, the difference between the highest mean BMI (in Pacific island countries, Kuwait, Bahrain, The Bahamas, Chile, the USA, and New Zealand for both boys and girls and in South Africa for girls) and lowest mean BMI (in India, Bangladesh, Timor-Leste, Ethiopia, and Chad for boys and girls; and in Japan and Romania for girls) was approximately 9–10 kg/m2. In some countries, children aged 5 years started with healthier height or BMI than the global median and, in some cases, as healthy as the best performing countries, but they became progressively less healthy compared with their comparators as they grew older by not growing as tall (eg, boys in Austria and Barbados, and girls in Belgium and Puerto Rico) or gaining too much weight for their height (eg, girls and boys in Kuwait, Bahrain, Fiji, Jamaica, and Mexico; and girls in South Africa and New Zealand). In other countries, growing children overtook the height of their comparators (eg, Latvia, Czech Republic, Morocco, and Iran) or curbed their weight gain (eg, Italy, France, and Croatia) in late childhood and adolescence. When changes in both height and BMI were considered, girls in South Korea, Vietnam, Saudi Arabia, Turkey, and some central Asian countries (eg, Armenia and Azerbaijan), and boys in central and western Europe (eg, Portugal, Denmark, Poland, and Montenegro) had the healthiest changes in anthropometric status over the past 3·5 decades because, compared with children and adolescents in other countries, they had a much larger gain in height than they did in BMI. The unhealthiest changes—gaining too little height, too much weight for their height compared with children in other countries, or both—occurred in many countries in sub-Saharan Africa, New Zealand, and the USA for boys and girls; in Malaysia and some Pacific island nations for boys; and in Mexico for girls. Interpretation The height and BMI trajectories over age and time of school-aged children and adolescents are highly variable across countries, which indicates heterogeneous nutritional quality and lifelong health advantages and risks

    Rising rural body-mass index is the main driver of the global obesity epidemic in adults

    Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities(.)(1,2) This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity(3-6). Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017-and more than 80% in some low- and middle-income regions-was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing-and in some countries reversal-of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories.Peer reviewe

    Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight NCD Risk Factor Collaboration (NCD-RisC)

    From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions

    Objetivos: El objetivo del estudio fue analizar los cambios en la densidad mineral ósea (DMO) a lo largo del tratamiento con inhibidores de aromatasa (IA) en la práctica clínica y evaluar la asociación entre el gen CYP11A1 y la variación de DMO al final del tratamiento. Material y métodos: La cohorte B-ABLE es un estudio prospectivo de mujeres postmenopáusicas con cáncer de mama, en tratamiento con IA. Se analizó la variación de DMO durante todo el tratamiento con IA, así como las diferencias entre las pacientes tratadas y no-tratadas previamente con tamoxifeno (TMX). Tres polimorfismos (rs4077581, rs11632698 y rs900798) del gen CYP11A1, fueron genotipados para su asociación con la variación de DMO. Resultados: Las pacientes tratadas con TMX mostraron pérdidas más aceleradas de DMO que las no tratadas previamente con TMX (60% menos en columna y 46% en fémur a los 2 años y 70% menos en columna y 63% en fémur a los 3 años). No obstante, al final del tratamiento no se detectaron diferencias significativas en la pérdida de DMO entre ambos grupos de pacientes. Los 3 polimorfismos del gen CYP11A1 resultaron significativamente asociados a la variación de DMO en fémur al final del tratamiento. Conclusiones: La DMO disminuyó de forma más acelerada en las pacientes con tratamiento previo con TMX que en las que solo recibieron AI, a pesar de que no se detectaron diferencias significativas al final de tratamiento. Polimorfismos en el gen CYP11A1 están relacionados con la variación de la DMO en respuesta al tratamiento con IA.Objectives: The aim of this study was to analyze bone mineral density (BMD) changes throughout aromatase inhibitor (AI) treatment in clinical cases and also consider its association with the CYP11A1 gene and the BMD variation after treatment. Material and methods: The B-ABLE cohort is a prospective study of postmenopausal women with breast cancer, in AI treatment. BMD variation was analyzed during AI treatment, as well as the differences those patients who were treated and not treated previously with tamoxifen (TMX). Three polymorphisms (rs4077581, rs11632698 and rs900798) of the CYP11A1 gene were genotyped for their association with BMD variation. Results: TMX-treated patients presented more rapid BMD loss than those who did not undergo prior TMX treatment (60% less in spine and 46% in femur at 2 years and 70% less in the spine and 63% in the femur at 3 years). However, no significant BMD loss was detected after treatment in either group. The 3 CYP11A1 gene polymorphisms were significantly associated with BMD variation in the femur at the end of the treatment. Conclusions: BMD was reduced more rapidly in patients with prior TMX treatment than in those who only received AI, although no significant differences were detected after treatment. The 3 CYP11A1 gene polymorphisms were associated with BMD variation in response to AI treatment.Este trabajo ha sido financiado por la Red Temática de Investigación Cooperativa en Envejecimiento y Fragilidad (RETICEF; RD12/0043/0022), y las ayudas FIS PI10/01464 y PI13/00444 (Instituto de Salud Carlos III, Ministerio de Ciencia e Innovación).

    Optimal growth and development in childhood and adolescence is crucial for lifelong health and well-being1–6. Here we used data from 2,325 population-based studies, with measurements of height and weight from 71 million participants, to report the height and body-mass index (BMI) of children and adolescents aged 5–19 years on the basis of rural and urban place of residence in 200 countries and territories from 1990 to 2020. In 1990, children and adolescents residing in cities were taller than their rural counterparts in all but a few high-income countries. By 2020, the urban height advantage became smaller in most countries, and in many high-income western countries it reversed into a small urban-based disadvantage. The exception was for boys in most countries in sub-Saharan Africa and in some countries in Oceania, south Asia and the region of central Asia, Middle East and north Africa. In these countries, successive cohorts of boys from rural places either did not gain height or possibly became shorter, and hence fell further behind their urban peers. The difference between the age-standardized mean BMI of children in urban and rural areas was <1.1 kg m–2 in the vast majority of countries. Within this small range, BMI increased slightly more in cities than in rural areas, except in south Asia, sub-Saharan Africa and some countries in central and eastern Europe. Our results show that in much of the world, the growth and developmental advantages of living in cities have diminished in the twenty-first century, whereas in much of sub-Saharan Africa they have amplified
