Introdução: Policiais frequentemente enfrentam alto estresse e estão sujeitos a riscos cardiovasculares como hipertensão, sobrepeso, e dislipidemia. Identificar a relação entre o estresse e marcadores cardiovasculares precoces pode ajudar a detectar pessoas em risco. Objetivo: Comparar a função autonômica e qualidade do sono entre policiais com e sem estresse. Métodos: Vinte e três policiais (39±7 anos; 28.8±4.2 kg/m²) foram divididos em dois grupos: com e sem estresse, definido pelo Inventário de Sintomas de Estresse de Lipp. Medidas consistiram em padrões de sono (polissonografia) e modulação autonômica (pressão arterial [PA], variabilidade da frequência cardíaca) durante o repouso, e em resposta ao estresse físico (teste de handgrip), e mental (teste de Stroop). O teste de Mann-Whitney U comparou policiais com e sem estresse. Resultados: Policiais com estresse apresentaram maior frequência cardíaca durante o sono (63±9 bpm vs. 55±12 bpm, p=0.031), quantidade de ronco (530±225 vs. 158±247; p=0.003), e PA diastólica de pico (116±20 mmHg vs. 95±21 mmHg; p=0.046) durante o teste de handgrip comparado aos policiais sem estresse. Conclusão: Policiais com estresse apresentam pior qualidade do sono e função autonômica comparado a policiais sem estresse.
