In Norway it is recommended that the overnight fast should notexceed 11 hrs for elderly nursing home residents.Methods: Overnight fast and nutritional status was examined for 342 long-term nursing home residents.

Median overnight fast was 15 hrs. Among the participants for whomthe overnight fast exceeded 11 hrs, 35.6% were in middle or high risk of malnutrition, and 20% were underweight with BMI < 20 kg/m2.No differences in overnight fast were observed between the different categories of nutritional status in this group.Conclusion: For many participants the overnight fast exceeded recommended length. Future studies should further examine the significanceof having an overnight fast below or above 11 hrs with respect to nutritional status for elderly nursing home residents.
