Resumo: The objective of this study was to verify the predictive validity of reference equations for hand grip strength (HGS) in middle-aged and elderly Brazilian men. We evaluated 60 men with age of 58.7±8.6 years, height 168.7±8.0 cm, body mass 67.9±13.0 kg, and body mass index 23.7±4.0 kg/m², utilizing the gold standard equipment for evaluation of HGS and following all methodological recommendations of the American Society of Hand Therapists (ASTH). The results of the Bland-Altman diagram for the dominant hand (DH) had a mean error (bias) of -8.4% (95%CI -51.6-34.7). The Bland-Altman diagram for the non-dominant hand (NDH) had a mean error (bias) of 1.4% (95%CI -47.1-49.8). The calculation of Cronbach's alpha was 0.69 for the DH and 0.59 for the NDH. The intraclass correlation coefficient was 0.52 (95%CI 31-68) for the DH and 0.42 (95%CI 20-60) for the NDH. We therefore conclude that the reference equations for HGS evaluated in this study has low predictive validity for a population of Brazilian men middle-aged and elderly, and may lead to a misinterpretation of the results.

O objetivo deste estudo foi verificar a validade preditiva das equações de referência para predição da força de preensão manual (FPM) em homens brasileiros de meia idade e idosos. Foram avaliados 60 homens com idade de 58,7±8,6 anos (50-84 anos), estatura 168,7±8,0 cm, massa corporal 67,9±13,0 kg e índice de massa corporal 23,7±4,0 kg/m², utilizando equipamento 'padrão-ouro' na avaliação da FPM e seguindo todas as recomendações metodológicas preconizadas pela American Society of Hand Therapists (ASHT). Os resultados do diagrama de Bland-Altman para mão dominante (MD) apresentam um erro médio (viés) de -8,4% (IC95% -51,6-34,7). Já o diagrama de Bland-Altman para mão não dominante (MND) apresenta um erro médio (viés) de 1,4% (IC95% -47,1-49,8). O cálculo de Cronbach's alpha para a MD foi de 0,69 e 0,59 para MND. O coeficiente de correlação intraclasse para MD foi 0,52 (IC95% 31-68) e de 0,42 (IC95% 20-60) para a MND. Concluímos que as equações para predição analisadas neste estudo, para uma população de homens brasileiros de meia idade e idosos, apresentou baixa validade preditiva, o que pode gerar erros de interpretação dos resultados.
