Association of eating behaviours with diurnal preference and rotating shift work in Japanese female nurses: a cross-sectional study.

Objectives: Our study examines differences in eating behaviour between day workers and rotating shift workers, and considers whether diurnal preference could explain the differences.

Methods: Japanese female nurses were studied (39 day workers and 123 rotating shift workers, aged 21-63 years) using self-administered questionnaires. The questionnaires assessed eating behaviours, diurnal preference and demographic characteristics.
