Estudio de la relación entre dieta y comportamientos sedentarios en una muestra de población infantil.
En este trabajo se estudió la asociación entre el consumo de ciertos alimentos y bebidas y los comportamientos sedentarios en un grupo de preescolares de Europa. Para realizar este estudio se contó con 6.853 niños a los que se les administró un cuestionario con preguntas para valorar su nivel de sedentarismo y consumo de alimentos. La relación entre ambos factores, se estudió mediante el programa estadÃstico SPSS. Con respecto al tiempo dedicado a ver la televisión se observó que el 70% de los niños dedicaban más de 1 hora al dÃa a ver la televisión durante los fines de semana, siendo este porcentaje de 42,1% (chicas) y 44,5% (chicos) entre semana. Más de la mitad de la muestra jugaban con consolas más de 1 hora/dÃa todos los dÃas de la semana, aumentando en aproximadamente un 25% cuando se trataba de los fines de semana. Respecto al consumo de alimentos se observó, un mayor consumo de cereales y zumos azucarados frente a los cereales no azucarados y zumos y frutas naturales. Además, se observó un alto consumo de bollerÃa industrial y postres azucarados, observándose una frecuencia de consumo de 1,9 raciones al dÃa, siendo que se consideran alimentos de consumo ocasional. En cuanto a la relación entre ambas conductas, se observó que ver la televisión poco tiempo, se asociaba positivamente con el consumo de agua y negativamente con el consumo de bebidas gaseosas, bollerÃa industrial y aperitivos salados (p<0,005). En cuanto a la asociación con los juegos inactivos, la relación es similar pero solo existe significación para el consumo de pasteles y dulces. Para el uso del ordenador, la significación se observó para el consumo de refrescos, pasteles, dulces y aperitivos en chicas. Estos resultados ponen de manifiesto una clara relación entre el consumo de alimentos poco saludables y el aumento del tiempo dedicado a actividades sedentarias
Fluid intake habits of spanish children and adolescents: an update of the Liq.In7 survey
Insufficient and unhealthy total fluid intake (TFI), especially in early stages of life, may have negative health impact [1]. Understanding how fluid consumption may differ throughout the day or as a function of location could help drive policy initiatives to encourage healthier drinking habits, especially in young population groups, so this study assesses current patterns of fluid consumption in children and adolescents in Spain, including drinking occasions and locations and to compare TFI with the adequate intake of water from fluids recommended by the European Food Safety Authority (EFSA)..
Veganism, vegetarianism, bone mineral density, and fracture risk: a systematic review and meta-analysis
Context
The numbers of vegans and vegetarians have increased in the last decades. However, the impact of these diets on bone health is still under debate.
Objective
This systematic review and meta-analysis sought to study the impact of vegetarian and vegan diets on bone mineral density (BMD) and fracture risk.
Data Sources
A systematic search was conducted of PubMed, Scopus, and Science Direct, covering the period from the respective start date of each database to November 2017.
Data Extraction
Two investigators evaluated 275 studies against the inclusion criteria (original studies in humans, written in English or Spanish and including vegetarian or vegan diets and omnivorous diets as factors with BMD values for the whole body, lumbar spine, or femoral neck and/or the number of fractures as the outcome) and exclusion criteria (articles that did not include imaging or studies that included participants who had suffered a fracture before starting the vegetarian or vegan diet). The quality assessment tool for observational cohort and cross-sectional studies was used to assess the quality of the studies.
Results
Twenty studies including 37 134 participants met the inclusion criteria. Compared with omnivores, vegetarians and vegans had lower BMD at the femoral neck and lumbar spine and vegans also had higher fracture rates.
Conclusions
Vegetarian and vegan diets should be planned to avoid negative consequences on bone health
Associations between pedometer-determined physical activity and adiposity in children and adolescents: Systematic review
The present review sought to examine the recent evidence on associations between objectively physical activity determined by pedometer and adiposity. A search for observational studies was carried out using database Pubmed in May 2013. Of 278 potentially eligible papers, 34 papers were included. Most studies (28/34; 82%) were crosssectional and all used proxies for adiposity, such as body mass index (BMI) or BMI z-score as the outcome measure. Few studies (9%; 3/34) focused on pre-school children. There was consistent evidence of negative associations between pedometer-determined physical activity and adiposity: significant negative associations were observed in 24/34 (71%) of studies overall. The present review supports the hypothesis that higher levels of habitual physical activity are protective against child and adolescent obesity. However, prospective longitudinal studies are warranted; there is a need for more research on younger children, and for more ‘dose-response’ evidence
Changes in physical activity patterns from adolescence to young adulthood: the BELINDA study
Physical activity (PA) is recognized as a marker of health. The aim was to investigate PA differences from adolescence to young adulthood. European adolescents included in the HELENA study were invited to participate in a follow-up study, 10 years later. The present study included 141 adults (25.0 ± 1.4 years) for whom valid accelerometer data were available in adolescence and adulthood. Changes in PA by sex, weight and maternal education level were explored with interactions. Time spent in sedentary activity, light PA (LPA) and moderate PA (MPA) increased by 39.1, 59.6 and 6.6 min/day, respectively, whereas the time spent in vigorous PA (VPA) decreased by 11.3 min/day compared with adolescent VPA (p < 0.05). Increases in MPA were greater on weekends compared with weekdays, but we found a greater decrease in VPA on weekdays compared with weekends. Moderate-to-vigorous PA (MVPA) decreased significantly on weekdays (–9.6 min/day; 95%CI, –15.9 to –3.4), while it increased on weekends (8.4 min/day; 95%CI, 1.9 to 14.8). Significant heterogeneity was found across sexes for VPA and MVPA, with a stronger decrease in VPA in males compared with females and a significant decrease in MVPA (–12.5 min/day; 95%CI, –20.4 to –4.5) in males but not in females (1.9 min/day; 95%CI, –5.5 to 9.2). No significant heterogeneity was found to be linked to maternal education level or weight, irrespective of PA level.
Conclusion: Our data suggest that the transition from adolescence to young adulthood is a critical period for lifestyle PA habits. A decline in VPA and an increasingly sedentary time were observed. The observed changes are worrying and may increase the risk of developing adverse health consequences later in life
Worldwide trends in hypertension prevalence and progress in treatment and control from 1990 to 2019: a pooled analysis of 1201 population-representative studies with 104 million participants.
BACKGROUND: Hypertension can be detected at the primary health-care level and low-cost treatments can effectively control hypertension. We aimed to measure the prevalence of hypertension and progress in its detection, treatment, and control from 1990 to 2019 for 200 countries and territories. METHODS: We used data from 1990 to 2019 on people aged 30-79 years from population-representative studies with measurement of blood pressure and data on blood pressure treatment. We defined hypertension as having systolic blood pressure 140 mm Hg or greater, diastolic blood pressure 90 mm Hg or greater, or taking medication for hypertension. We applied a Bayesian hierarchical model to estimate the prevalence of hypertension and the proportion of people with hypertension who had a previous diagnosis (detection), who were taking medication for hypertension (treatment), and whose hypertension was controlled to below 140/90 mm Hg (control). The model allowed for trends over time to be non-linear and to vary by age. FINDINGS: The number of people aged 30-79 years with hypertension doubled from 1990 to 2019, from 331 (95% credible interval 306-359) million women and 317 (292-344) million men in 1990 to 626 (584-668) million women and 652 (604-698) million men in 2019, despite stable global age-standardised prevalence. In 2019, age-standardised hypertension prevalence was lowest in Canada and Peru for both men and women; in Taiwan, South Korea, Japan, and some countries in western Europe including Switzerland, Spain, and the UK for women; and in several low-income and middle-income countries such as Eritrea, Bangladesh, Ethiopia, and Solomon Islands for men. Hypertension prevalence surpassed 50% for women in two countries and men in nine countries, in central and eastern Europe, central Asia, Oceania, and Latin America. Globally, 59% (55-62) of women and 49% (46-52) of men with hypertension reported a previous diagnosis of hypertension in 2019, and 47% (43-51) of women and 38% (35-41) of men were treated. Control rates among people with hypertension in 2019 were 23% (20-27) for women and 18% (16-21) for men. In 2019, treatment and control rates were highest in South Korea, Canada, and Iceland (treatment >70%; control >50%), followed by the USA, Costa Rica, Germany, Portugal, and Taiwan. Treatment rates were less than 25% for women and less than 20% for men in Nepal, Indonesia, and some countries in sub-Saharan Africa and Oceania. Control rates were below 10% for women and men in these countries and for men in some countries in north Africa, central and south Asia, and eastern Europe. Treatment and control rates have improved in most countries since 1990, but we found little change in most countries in sub-Saharan Africa and Oceania. Improvements were largest in high-income countries, central Europe, and some upper-middle-income and recently high-income countries including Costa Rica, Taiwan, Kazakhstan, South Africa, Brazil, Chile, Turkey, and Iran. INTERPRETATION: Improvements in the detection, treatment, and control of hypertension have varied substantially across countries, with some middle-income countries now outperforming most high-income nations. The dual approach of reducing hypertension prevalence through primary prevention and enhancing its treatment and control is achievable not only in high-income countries but also in low-income and middle-income settings.

Effect of lean red meat from beef (Pirenaica breed) versus lean white meat consumption on diet quality: a randomized-controlled crossover study in healthy young adults
A randomized crossover study was carried out in three University accommodation halls. Participants consumed either beef (Pirenaica breed) (PB) or conventional chicken (CC) three times per week for an 8-week periods with their usual diet, each one separated by a 5-week wash out period. Dietary variables were recollected by the Food Frequency Questionnaire (FFQ), and the Diet Quality Index (DQI) was calculated. Forty-seven healthy adults were included (19.9 ± 1.75 years). The inclusion of both types of diets did not modify the components of the DQI, such as the diversity, equilibrium, adequacy and excess. However, when only the first period was analyzed, a significant decrease in the consumption of fruits and vegetables was observed in those participants who received the PB diet (intervention group). The CC diet (control group) significantly reduced the consumption of fish and eggs, total DQI, and DQI quality component. The expected effect was observed in the significant increment of consumption of red meat after the intervention period
