Summary
Accurate body weight estimation for nonambulant elderly patients is possible using simple anthropometric measurements. Nomograms based on arm circumference, chest girth, waist skinfold, and thigh circumference provide a safe and easy method.
Area of Science:
- Geriatric Medicine
- Anthropometry
- Clinical Nutrition
Background:
- Accurate body weight (BW) assessment is crucial for elderly patients, especially those who are nonambulant.
- Traditional weight measurement can be challenging in this population.
- Existing methods may lack accuracy or ease of use.
Purpose of the Study:
- To develop a safe, easy, and accurate method for estimating body weight in nonambulant elderly individuals.
- To identify key anthropometric measurements that correlate with body weight in this demographic.
Main Methods:
- An anthropometric study involving 211 inpatients (108 males, 103 females) at the University Department of Geriatric Medicine.
- Collection of various skinfold thicknesses and circumferences, alongside body weight.
- Utilized Harpenden Skin-Fold Calipers, tape measures, and bathroom scales for measurements.
Main Results:
- In males, body weight strongly correlated with arm circumference and chest girth.
- In females, body weight showed a high correlation with waist skinfold thickness and thigh circumference.
- Regression equations were used to construct nomograms for weight estimation in both sexes.
Conclusions:
- Nomograms derived from specific anthropometric measurements offer a convenient method for estimating body weight in nonambulant elderly patients.
- These nomograms can also serve as progress sheets to monitor changes in body weight, such as those due to dietary interventions.
