INTRODUÇÃO: Os seguranças frequentemente permanecem em posições estáticas prolongadas em pé, o que os predispõe a desvios posturais sutis e dores musculoesqueléticas. Apesar desse risco ocupacional, poucas pesquisas examinaram essas associações de forma abrangente. OBJETIVO: Investigar os desvios posturais nos planos anterior, posterior e sagital usando fotogrametria e explorar sua correlação com a dor musculoesquelética entre seguranças do sexo masculino. MÉTODOS: Um estudo transversal foi conduzido ao longo de 12 meses, envolvendo 100 seguranças masculinos com idades entre 30 e 50 anos. As variáveis posturais foram avaliadas utilizando o software Advanced Postural and Environmental Correction System (APECS) através de fotogrametria digital, enquanto a dor e os sintomas foram avaliados utilizando o Questionário Nórdico de Sintomas Musculoesqueléticos (QNSM) e a Escala Numérica da Dor (END/NPRS). A análise estatística incluiu estatísticas descritivas e correlação de postos de Spearman com correção de Benjamini–Hochberg. RESULTADOS: Foram encontrados desvios posturais significativos, especialmente no alinhamento dos ombros e do corpo nos planos coronais anterior e posterior (r = 0,612, p < 0,001; r = 0,524, p < 0,001). Uma correlação moderada foi observada entre a inclinação da EIAS (espinha ilíaca anterossuperior) e a dor lombar (r = 0,442, p = 0,002), enquanto a inclinação da EIPS (espinha ilíaca posterossuperior) mostrou uma correlação fraca (r = 0,260, p = 0,072). Outras variáveis posturais apresentaram correlações fracas ou não significativas com a dor musculoesquelética. CONCLUSÃO: Apesar das assimetrias posturais evidentes, apenas associações fracas a moderadas com a dor musculoesquelética foram observadas. Os achados reforçam a natureza multifatorial da dor ocupacional e destacam a importância de modificações ergonômicas e da variabilidade de movimento na prevenção da dor.
