Comparison of three methods for measuring height in rehabilitation inpatients and the impact on body mass index classification: An open prospective study

Abstract

AIM: To compare standing height, estimated current height and demi-span estimated height and examine their impact on body mass index (BMI) classification. METHODS: Cross-sectional data was collected on 104 patients admitted to an adult rehabilitation ward and seen by the dietitian. Patient's standing, estimated current height and demi-span estimated height were collected and grouped by age: 19-64 and ≥65 years. RESULTS: The limits of agreement (95% confidence interval) for estimated current height compared with standing height were +9.9 cm and -7.9 cm, in contrast to +8.7 cm and -14.3 cm for demi-span estimated height. Demi-span underestimated height when compared with standing height in bot..
