Objetivos: estudar a associação entre privação de sono e obesidade em trabalhadores.
Métodos: Foi conduzido um estudo transversal com trabalhadores de uma manufatura de cadernos no sul do Brasil, que possui três setores de trabalho (linha de produção, setor administrativo e logística), sendo que o setor de produção trabalha 24 horas por dia. Características demográficas, socioeconômicas, ocupacionais e comportamentais foram obtidas através de um questionário autopreenchível, padronizado e pré-testado. As medidas de peso e altura foram autorreferidas e o índice de massa corporal calculado. O ponto de corte para obesidade foi de ≥30 kg/m². A duração do sono foi categorizada em no mínimo seis horas por dia e menos de seis horas por dia (privação do sono). Para análise bivariada, foi utilizado o teste do Qui-quadrado e o teste de tendência linear. As razões de prevalência brutas e ajustadas foram calculadas pela Regressão de Poisson.
Resultados: A amostra final contou com 193 trabalhadores, com média de idade de 34±11 anos, sendo 99 (51%) mulheres. A prevalência de obesidade foi de 27 (13,98%), e a prevalência de privação do sono foi de 40 (20,7%). A privação de sono foi associada ao setor de produção (p=0,011), ao turno noturno (p<0,001) e à inatividade física (p=0,003). A presença de obesidade foi associada à privação do sono (p=0,006). Após o controle para possíveis fatores de confusão, a probabilidade de ser obeso foi de 2,37 (IC 95% 1,08-5,21) vezes maior entre trabalhadores em privação de sono.
Conclusões: Os resultados demostraram associação entre privação de sono e obesidade. Além disso, a privação de sono foi associada ao trabalho no turno noturno.
