Differences in daily in-hospital physical activity and geriatric nutritional risk index in older cardiac inpatients: preliminary results

Little is known about the differences in the geriatric nutritional risk index (GNRI) status in older patients and their relationship to accelerometer-derived measures of physical activity (PA) levels. We determined both differences in daily measured PA based on the GNRI and related cut-off values for PA in elderly cardiac inpatients. We divided 235 consecutive elderly cardiac inpatients (mean age 73.6 years, men 70.6 %) into four groups by age and GNRI: older-high group, 65–74 years with high GNRI (≥92 points) (n = 111); older-low group, low GNRI (
