Assessing the accuracy and reliability of linear growth measurement techniques in children: A comprehensive investigation

Abstract

Background:Linear growth measurement is crucial for assessing children's health and development. However, the accuracy and reliability of these measurements can vary depending on several factors. This study aims to investigate the accuracy and reliability of linear growth measurement techniques in Iraqi children. Objective:To evaluate the accuracy and reliability of different linear growth measurement techniques utilized in Iraqi children and identify factors influencing their accuracy and reliability. Methods:This study was conducted at six primary health care settings in Iraq, including 250 participants. Parents of children visiting these centers completed a questionnaire developed after extensive literature review. The study population primarily consisted of infants (38.0%) from urban areas (73.6%), with a slight male predominance (57.6%). Results:Most children were classified as having "Excellent" health (56.0%), and the majority of households were high-income (82.4%). Stature assessments were prevalent (73.6%), while sitting height and arm span measurements were less common (6.4% and 7.2%, respectively). Significant variations in stature were observed between urban and rural children (p = 0.001), with no significant differences in sitting height and arm span (p>0.05). Age was a consistent predictor of stature and sitting height, with significant associations with urban residency and child health status (p
