La literatura científica sobre el consumo de suplementos deportivos (SD) en levantamiento de potencia es escasa. El objetivo del presente estudio fue evaluar el consumo de SD y la ingesta de proteína dietética en un grupo de levantadores de peso que compiten a nivel nacional. Se utilizaron enfoques experimentales y no experimentales, registrándose un total de 22 cuestionarios y diarios dietéticos. Los resultados muestran que el 100% de los sujetos afirma haberlos consumido en alguna ocasión y el 96,9% los consume en la actualidad. Los SD más consumidos por la muestra son monohidrato de creatina (100%), cafeína (95%), proteína de suero (92%), aminoácidos ramificados (73%), barritas energéticas (68%), ácidos grasos omega-3 (63%), bebidas isotónicas (63%) y complejos vitamínicos (59%). La mayoría (36,4%) no prevé en qué momento del día consumirlos. Durante el transcurso del diario dietético, los SD más consumidos fueron la proteína de suero y el monohidrato de creatina; además, los sujetos ingirieron una media de 2.37 g/kg/día de proteína dietética. Teniendo en cuenta el presente estudio y otras aportaciones en la bibliografía, podemos afirmar que la ingesta de proteína dietética en levantadores de peso es suficiente para la ganancia y preservación de masa muscular; y que el consumo de SD es elevado y cada vez más frecuente, lo que puede ocasionar serios riesgos de salud pública debido a la falta de información existente en el sector, e inespecífica y mejorable legislación de los SD en Europa.Abstract. The scientific literature on the consumption of sports supplements (SS) within powerlifting is scarce. The goal of the study was to evaluate the consumption of SS and dietary protein intake in a national-level powerlifting group. Experimental and non-experimental approaches were used with a total of 22 surveys and dietary logs. The results show that 100% of the subjects claimed to have consumed SS at some point and 96.9% of them are currently consuming them. The most consumed SS are creatine monohydrate (100%), caffeine (95%), whey protein (92%), branched-chain amino acids (73%), energy bars (68%), omega-3 fatty acids (63%), isotonic drinks (63%) and multivitamin complex (59%). Most of the subjects (36.4%) do not plan when to consume them throughout the day. According to the dietary logs of the subjects, the most taken SS were whey protein and creatine monohydrate; furthermore, the subjects consumed an average of 2.37 g/kg/day of dietary protein. Taking into account this study and other studies, we can confirm that the protein intake of powerlifters is enough to fuel muscle gain and maintenance; and that the consumption of SS is high and that it is continuously growing, which may cause serious public-health issues in the future due to the lack of information within the fitness industry and the unspecific and undeveloped legislation of SS within Europe.

Humans under-consume fish, especially species high in long-chain omega-3 fatty acids. Food-based dietary guidelines are one means for nations to encourage the consumption of healthy, nutritious food. Here, associations between dietary omega-3 consumption and food-based dietary guidelines, gross domestic product, the ranked price of fish, and the proportions of marine fish available at a national level were assessed. Minor associations were found between consumption and variables, except for food-based dietary guidelines, where calling out seafood in FBDGs did not associate with greater consumption. This relationship was explored for consumers in the United States, and it was observed that the predominant seafood they ate, shrimp, resulted in little benefit for dietary omega-3 consumption. Seafood is listed under the protein category in the U.S. Dietary Guidelines, and aggregating seafood under this category may limit a more complete understanding of its nutrient benefits beyond protein.

Abstract Background The aim of this study was to analyze the consumption of sports supplements (SS) in competitive level fencers and compare differences based on sex and competitive level (international and national). Methods A total of 49 fencers (18 men and 31 women) of national (n = 16) and international (n = 33) level completed a questionnaire with questions about SS consumption and the possible repercussions on health and / or sports performance. The results were analyzed based on the different categorizations established by the Australian Institute of Sport (AIS), as well as by sex and level of competence to which the participants belonged to. Results 46.9% of fencers have consumed SS with the main motivation being performance improvement (34.2%). Medical doctors were the individuals who were more likely to advise men to consume SS (50.0% vs 5.6%; OR = 3.29 [1.50–7.20]). Friends were most likely to advise women (38.9% vs 8.3%; OR = 1.75 [1.05–2.93]). The most consumed SS were sport drinks (44.9%), vitamin C (43.4%), sport bars (38.8%), and caffeine (28.6%). In regards to the SS categories, it was observed differences in the interaction level·sex in medical supplements (p = 0.017). In addition, there was a higher prevalence of whey protein consumption in women (25.8% vs 0%; p = 0.020) and iron consumption in men (33% vs 6.5%; p = 0.039). Conclusions The prevalence of SS use in fencers is within the values previously reported in athletes of the same competitive level. There were no differences by sex and competitive level in the total consumption of SS, nor in each of the groups of level of evidence, being sport drinks, bars and caffeine the most consumed SS.

Abstract Background Propionic acidemia (PA), an inborn error of metabolism, is caused by a deficiency in propionyl-CoA carboxylase. Patients have to follow a diet restricted in the propiogenic amino acids isoleucine (Ile), valine (Val), methionine (Met) and threonine (Thr); proper adherence can prevent and treat acute decompensation and increase life expectancy. However, chronic complications occur in several organs even though metabolic control may be largely maintained. Bone marrow aplasia and anemia are among the more common. Materials and methods In this retrospective study, data for patients with PA being monitored at the Hospital Ramón y Cajal (Madrid, Spain) (n = 10) in the past 10 years were examined to statistically detect relationships between persistent severe anemia outside of metabolic decompensation episodes and dietary practices such as natural protein intake and medical food consumption (special mixture of precursor-free amino acids) along with plasma levels of branched-chain amino acids (BCAA). High ferritin levels were deemed to indicate that a patient had received repeated transfusions for persistent anemia since data on hemoglobin levels at the moment of transfusion were not always passed on by the attending centers. Results Three patients had severe, persistent anemia that required repeated blood transfusions. Higher medical food consumption and plasma Leu levels were associated with iron overload. Notably, natural protein intake and plasma Val were negatively correlated with ferritin levels. We also observed an inverse relationship between plasma Val/Leu and Ile/Leu ratios and ferritin. Conclusion The present results suggest that severe anemia in patients with PA might be associated with low natural protein intake and BCAA imbalance.

Diet in the first years of life is an important factor in growth and development. Dietary protein is a critical macronutrient that provides both essential and nonessential amino acids required for sustaining all body functions and procedures, providing the structural basis to maintain life and healthy development and growth in children. In this study, our aim was to describe the total protein intake, type and food sources of protein, the adequacy to the Population Reference Intake (PRI) for protein by the European Food Safety Authority (EFSA), and the Recommended Dietary Allowance (RDA) by the Institute of Medicine (IoM). Furthermore, we analyzed whether the consumption of dairy products (including regular milk, dairy products, or adapted milk formulas) is associated with nutrient adequacy and the contribution of protein to diet and whole dietary profile in the two cohorts of the EsNuPI (in English, Nutritional Study in the Spanish Pediatric Population) study; one cohort was representative of the Spanish population from one to < 10 years old (n = 707) (Spanish reference cohort, SRS) who reported consuming all kinds of milk and one was a cohort of the same age who reported consuming adapted milk over the last year (including follow-on formula, growing up milk, toddler’s milk, and enriched and fortified milks) (n = 741) (adapted milk consumers cohort, AMS). The children of both cohorts had a high contribution from protein to total energy intake (16.79% SRS and 15.63% AMS) and a high total protein intake (60.89 g/day SRS and 53.43 g/day AMS). We observed that protein intake in Spanish children aged one to < 10 years old was above the European and international recommendations, as well as the recommended percentages for energy intakes. The main protein sources were milk and dairy products (28% SRS and 29% AMS) and meat and meat products (27% SRS and 26% AMS), followed by cereals (16% SRS and 15% AMS), fish and shellfish (8% in both cohorts), eggs (5% SRS and 6% AMS), and legumes (4% in both cohorts). In our study population, protein intake was mainly from an animal origin (meat and meat products, milk and dairy products, fish and shellfish, and eggs) rather than from a plant origin (cereals and legumes). Future studies should investigate the long-term effect of dietary protein in early childhood on growth and body composition, and whether high protein intake affects health later in life.

Providing refugees with psychosocial support is particularly important considering the high level of mental health problems prevalent in this population. A psychosocial walk-in clinic operating within a state reception and registration center in Germany has been supporting mentally burdened refugees since 2016. This study focused on patients’ perspectives on their mental health burden, the psychosocial walk-in clinic, and future help seeking. We conducted interviews with n = 22 refugees attending the walk-in clinic from March to May 2019. Qualitative analysis focused on the following four topics: (1) mental burden from the patients’ perspective, (2) access to the psychosocial walk-in clinic, (3) perception of counseling sessions, and (4) perception of follow-up treatment. The results show that the majority of interviewees were burdened by psychological and somatic complaints, mostly attributed to past experiences and post-migratory stress. Therapeutic counseling and psychiatric medication were found to be particularly helpful. Most of the participants felt motivated to seek further psychosocial support. Key barriers to seeking psychosocial help included shame, fear of stigma, and lack of information. Overall, the psychosocial walk-in clinic is a highly valued support service for newly arrived refugees with mental health issues.

Abstract Objective Provide a synthesis of the COVID-19 policies targeting older people in Chile, stressing their short- and long-term challenges. Method Critical analysis of the current legal and policy measures, based on national-level data and international experiences. Results Although several policies have been enacted to protect older people from COVID-19, these measures could have important unintended negative consequences in this group’s mental and physical health, as well as financial aspects. Discussion A wider perspective is needed to include a broader definition of health—considering financial scarcity, access to health services, mental health issues, and long-term care—in the policy responses to COVID-19 targeted to older people in Chile.
