Reliability and Technical Error of Calf Circumference and Mid-half Arm Span Measurements for Nutritional Status Assessment of Elderly Persons in Malaysia

| Summary: | This study sought to examine the reliability of two measurements; Calf Circumference
(CC) and Mid-half Arm Span (MHAS). A sample of 130 elderly persons aged 60 years
and above seen consecutively in the Kuala Lumpur Hospital outpatient clinic during
the period of December 2005 to January 2006, upon consent, were recruited to the
study. There was a high degree of reliability for both inter- and intra-examiner (r close
to 1). For inter-examiner, on average the CC measurements taken by the first examiner
were 0.3 cm lower than that of the second examiner. The upper and lower limit of the
differences were +0.4 to –0.9 cm respectively. Inter-examiner MHAS measurements
on average by the first examiner were 0.2 cm lower than that of the second examiner.
The limits were +1.7 to –2.1 cm. By comparison, the inter-examiner CC measurements
were more reliable than the MHAS measurements. For intra-examiner, on average the
CC measurements at Time 1 were consistent with Time 2 (mean difference=0) with
limits of the difference at + 0.5 cm. MHAS measurements at Time 1 were on average
0.1 cm less than at Time 2 with limits at +1.7 and –1.8 cm. The technical error of
measurement (TEM) and coefficient of variation of CC and MHAS for both interexaminer
and intra-examiner measurements were within acceptable limits with the
exception of MHAS TEM. This study suggests that CC and MHAS measured in elderly
persons 60 years and above, using Seca Circumference Tape ® 206, Germany (0.05 cm)
are reliable and can be used in a community survey.
