Resumo
No Brasil, os suplementos alimentares (SA) são regulamentados pela Agência Nacional de Vigilância Sanitária (ANVISA), que os define como não medicamen tos, que não podem ser usados para tratar, curar ou prevenir doenças. Em Por tugal, os SA são regulamenados pela Comissão Europeia (CE) e classificados como géneros alimentícios, sendo fontes de vitaminas e minerais concentradas e de outras substâncias com ação fisiológica e nutricional. Neste enquadramento foi desenvolvido um estudo transversal quantitativo ana lítico, para conhecer as atitudes e perceções do uso do SA por praticantes de atividade física (AF), bem como a sua auto-prescrição e o seu uso indiscrimi nado. O objetivo geral do projeto foi obter dados sobre o consumo de SA numa amostra de conveniência de praticantes de AF recreativa em academias e giná sios, residentes em Portugal e no Brasil, através de inquéritos online de resposta anónima.O estudo é baseado num questionário original construído com base nas questões e hipóteses de investigação, integrando o consentimento informado. Foram investigados o acesso aos SA, os motivos do consumo e as práticas mais atuais relacionadas com o uso dos SA. Utilizou-se a plataforma Google Forms e as redes sociais para divulgação do estudo aos praticantes de AF. Os dados recolhidos foram tratados com software SPSS®, obedecendo às boas práticas de proteção de dados pessoais. Contribuíram para o estudo 248 respondentes, 45% com idades entre 21 e 30 anos, dos quais 93% praticam AF diária e, mesmo com acompanhamento de profissional nutricionista (49%), adquirem SA online (63%) . Em todas as faixas etárias o nutricionista é que aconselha (37-45%), com exceção dos 51-80 anos onde quem indica é o médico (75%). Nos motivos para SA, estão perda de peso (45%), seguido de resistência (31%), fins estéticos (26%), ganho de peso (22%) e carências nutricionais (6%). Utilizaram creatina 201 (81%) como SA diário, 14 (6%) usaram emagrecedores, e 5 (2%) utilizaram SARM.
In Brazil, the National Health Surveillance Agency (ANVISA) regulates food sup plements, which are non-medicinal products that cannot be used to treat, cure, or prevent diseases. In Portugal, the European Commission (EC) regulates food supplements (FS/SA), classified as foodstuffs and sources of concentrated vita mins and minerals that have physiological and nutritional effects. In this context, a quantitative analytical cross-sectional study was developed to determine the attitudes and perceptions of practitioners of physical activity (PA) regarding the use of FS, as well as their self-prescription and discriminated use. The project's general aim was to obtain data on the consumption of FS in a con venience sample of practitioners of recreational PA in gyms and fitness centers, from residents in Portugal and Brazil, by carrying out an anonymous response survey. For the study, an original questionnaire was constructed based on the research questions and hypotheses supported in the literature and integrating the informed consent developed by the researchers of this work. FS access, reasons to consume, and more current practices related to the use of FS by the respond ents of both countries were investigated. It was launched as an online survey on the Google Forms platform and the data collected was processed using SPSS® software and complying with good personal data protection practices. This study covered 248 interviewees, 45% aged between 21 and 30 years old, of which 93% practice PA daily and, even with the support of a professional nutri tionist (49%), they purchase SA online (63%). In all age groups, the nutritionist advises (37-45%), except those aged 51-80 years, whom the doctor recommends (75%). The reasons for SA include weight loss (45%), followed by resistance (31%), aesthetic purposes (26%), weight gain (22%) and nutritional deficiencies (6%). Creatine was used by 201 (81%) as a daily SA, 14 (6%) used weight loss pills, and 5 (2%) used SARM.
