Autopercepción de una dieta correcta y realización de actividad física en estudiantes universitarios

This article aims to identify the self-perception of the coverage of correct diet characteristics in college students and the performance of physical activity in them. A cross-sectional, descriptive, analytical and observational study was carried out with 300 students from different semesters of the school year; A survey designed from validated instruments with items on eating habits and physical activity practice was applied, it was sent virtually to the students. It was found that 39% of the students do physical activity for 1-3 days, 36% for 3-5 days, 10% do it every day and 15% do not do physical activity outside of class; Regarding diet, 50% consider that their diet is adequate, 49% that it is complete, another 45% consider it balanced, 66% comply with the safety law, 58% of the students assume that their diet is sufficient and finally the 73% consider it varied. Concluding that the correct diet is covered by just over half of the student population and physical activity practices are part of their lifestyle, even with the many academic and extra-class activities in college life.Este artículo tiene por objetivo identificar la autopercepción del cubrimiento de características de dieta correcta en estudiantes universitarios y la realización de actividad física en los mismos. Se realizó un trabajo de tipo transversal, descriptivo, analítico y observacional con 300 alumnos y alumnas de distintos semestres del ciclo escolar; se aplicó una encuesta diseñada a partir de instrumentos validados con ítems sobre hábitos alimentarios y práctica de actividad física, se envió de forma virtual al alumnado. Se encontró que el 39% de los estudiantes realizan actividad física de 1-3 días, el 36% de 3-5 días, el 10% la realiza todos los días y un 15% no realiza actividad física fuera de clases; respecto a dieta, el 50% considera que su alimentación es adecuada, 49% que es completa, otro 45% la consideran equilibrada, el 66% cumple con ley de inocuidad, 58% de los estudiantes asumen que su alimentación es suficiente y finalmente el 73% la consideran variada. Concluyendo que la dieta correcta es cubierta por poco más de la mitad de la población estudiantil y las prácticas de actividad física son parte de su estilo de vida, aún con las múltiples actividades académicas y extra aula en la vida universitaria

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

Diminishing benefits of urban living for children and adolescents’ growth and development

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
