Table 3 Prospective associations between sleep duration categories and FV intakes of women from the UKWCS

From: Recommended sleep duration is associated with higher consumption of fruits and vegetables; cross-sectional and prospective analyses from the UK Women’s Cohort Study

Short sleepers (≤6 h/d) and Long sleepers (≥9 h/d) compared to the recommended group (7–9 h/d)
