Abstract Background: It is crucial to monitor blood lipid levels accurately in older adults to assess cardiovascular risk. Although several portable strip-based devices are commercially available, their accuracy has not been well established. Objective: To evaluate the agreement of the Mission Cholesterol device and standard laboratory method results, using samples from older adults. Methods: Forty-nine patients (42 females) with an average age of 70 ± 8 years were included. The participants were instructed to fast for 12 hours before undergoing venous and capillary blood sampling for lipid analysis (total cholesterol [TC], high-density lipoprotein cholesterol [HDL-C], low-density lipoprotein cholesterol [LDL-C], and triglyceride [TG] levels). The agreement between the Mission Cholesterol device and laboratory test results was assessed using the concordance correlation coefficient (CCC) and Bland–Altman plots. The accuracy levels were assessed based on the percentage bias recommended by the National Cholesterol Education Program (NCEP). Results: The TC measurement had a better accuracy level (bias = 10.91%; CCC = 0.89) than other lipid measurements. However, none of them met the NCEP's acceptable standards for bias and concordance (CCC ≥ 0.90). Furthermore, the device demonstrated modest overall agreement in classifying lipid risk according to clinical reference values (agreement rates: TC, 67.3%; HDL-C, 65.3%; LDL-C, 49.0%; and TG, 61.2%). Conclusion: The Mission Cholesterol device exhibited insufficient agreement levels for effective lipid profile monitoring and screening in older adults.

INTRODUÇÃO: Os esteroides anabólicos androgênicos (EAA) são substâncias, quimicamente semelhantes à testosterona, utilizadas para o tratamento/controle de diversas doenças. Contudo, tais substâncias estão sendo empregadas de forma não terapêutica e indiscriminada com finalidades de melhora da performance esportiva e principalmente estética. OBJETIVO: analisar a prevalência do uso e o conhecimento de EAA por estudantes e professores de educação física que atuam em academias de ginástica de Belém, PA. Utilizou-se para a coleta de dados um questionário fechado e anônimo, aplicado a 117 pesquisados. A comparação da prevalência do uso e o grau de conhecimento dos pesquisados sobre EAA foi realizada através de estatística não paramétrica, prova de X² (Qui-quadrado), considerando o intervalo de confiança de 95% e p < 0,05. A média de idade dos participantes da pesquisa foi de 28,0 ± 6,3 anos e a prevalência do uso de EAA foi de 31,6% do total de sujeitos pesquisados. A prevalência maior foi entre os profissionais especialistas (39,3%), tendo como principal motivação para o uso de EAA a estética com 75,6%. Em relação ao conhecimento, verificou-se que as drogas classificadas como EAA foram: Durateston®, Deca-Durabolin®, oxandrolona/Winstrol®. Entretanto, estes profissionais confundiram-se ao apontar outras substâncias como sendo EAA, entre elas: hormônio do crescimento e óleos localizados. Entre os efeitos colaterais, os mais citados foram: acne, engrossamento da voz e agressividade; contudo, efeitos colaterais mais prejudiciais como câncer e aromatização foram menos assinalados. RESULTADOS: Demonstraram que a prevalência de uso de EAA foi significativa (p < 0,03) entre os estudantes e professores de educação física que atuam em academias de Belém, PA, revelando assim prováveis desconhecimentos destes sobre alguns dos efeitos colaterais, podendo implicar no uso indiscriminado destas drogas.

Anabolic androgenic steroids (AAS) are chemically similar to testosterone, used for the treatment/control of various diseases. However, these substances are being used in non-therapeutic and indiscriminate purposes to improve sports performance and mainly esthetics. This study aimed to analyze the prevalence of AAS use and information of undergraduates and physical education teachers working in fitness centers in Belém-PA. A closed anonymous questionnaire was applied to 117 volunteers as an instrument. Comparison of the prevalence of use and degree of information of the respondents about AAS was performed using statistical non-parametric test X² (chi-square), considering the range of 95%, significant when p<0.05. The average age of the participants was 28.0 ± 6.3 years and the prevalence of AAS use was of 31.6%. The highest prevalence found was among specialist professionals (39.3%), the main motivation for the use of AAS was 75.6% to esthetics. Regarding the information, it was found that the drugs were classified as AAS: Durateston, Deca-Durabolin, Oxandrolona/Winstrol. However, these professionals took other substances for AAS, including: growth hormone and oils. Among the side effects, the most commonly cited were: acne, deepening of the voice and aggressiveness, but more harmful side effects such as cancer and flavor were less marked. The results of this study demonstrate that the use prevalence was significant (p<0.03) among the undergraduate and physical education teachers working in fitness centers of Belém-PA, evidencing hence probable misinformation about some of the side effects of AAS use, implying the indiscriminate use of these drugs.
