GİYİLEBİLİR BİOELEKTRİK İMPEDANS ÖLÇÜM CİHAZININ GEÇERLİLİK VE GÜVENİRLİĞİNİN ARAŞTIRILMASI

Vücut kompozisyonun değerlendirilmesi ve izlenmesi sağlık açısından önemlidir. Gelecekte vücut kompozisyonunu ölçen ve takip eden cihazların daha yaygın kullanılacağına inanılmaktadır. Bu çalışmanın amacı bant olarak tasarlanan giyilebilir biyoelektrik empedans ölçüm cihazının, güvenilirliğini ve geçerliliğini araştırmak amacıyla laboratuvar tipi biyoelektrik empedans cihazı ile karşılaştırmaktır. Bu çalışma tekrarlanan ölçümlerden oluşan bir laboratuvar çalışmasıdır. Çalışmaya 199 erkek, 123 kadın toplamda 322 sağlıklı kişi katılmıştır. Katılımcıların vücut kompozisyonları laboratuvar tipi biyoelektrik empedans cihazı ile ölçülerek kaydedildi. Daha sonra katılımcıların vücut kompozisyonları giyilebilir biyoelektrik empedans cihazı ile üç kez ölçülmüş ve veriler kaydedilmiştir. Hem laboratuvar tipi cihaz hem de giyilebilir ölçüm cihazı ile yapılan ölçümlerin sonuçları birbiriyle çok yüksek derecede korelasyon göstermiştir. Erkeklerde, kadınlarda ve tüm grupta iki cihazın yağ kütle ölçümleri arasında anlamlı fark bulunmamıştır. Kas kütlesi verileri değerlendirildiğinde, erkeklerde ve tüm grupta iki cihazın ölçümleri arasında anlamlı bir fark bulunmazken, kadınlarda anlamlı bir fark görülmüştür (p <0,001). Giyilebilir ölçüm cihazı, laboratuvar tipi biyoelektrik empedans cihazı ile karşılaştırıldığında, yağ kütlesi ölçümleri geçerli sonuçlar vermiştir. Kas kütlesi ölçümlerinde ise, sadece kadınların ölçümleri arasında bir farklılık bulunmuştur. Giyilebilir biyoelektrik empedans ölçüm cihazları güvenilirliği değerlendirildiğinde, cihazın güvenilir sonuçlar verdiği görülmüştür. Bu nedenle, cihazın vücut kompozisyonunu ölçme ve takip etme açısından faydalı olacağı sonucuna varılmıştır.

VALIDITY AND RELIABILITY OF THE WEARABLE BIOELECTRICAL IMPEDANCE MEASURING DEVICE

Assessing and monitoring body composition is important for health. It is believed that in the future, wearable devices measuring the body composition, will be more common. The purpose of this study is to compare a wearable bioelectrical impedance measuring device, designed as a band, with a laboratory type of bioelectrical impedance device in order to investigate its reliability and validity. A total of 322 healthy people, 199 men, and 123 women participated in the study. The participants’ body compositions were measured with the laboratory type of bioelectrical impedance device and recorded. Following these measurements, participants’ body compositions were measured three times with the wearable bioelectrical impedance measuring device and data were recorded. The results of the measurements by both the laboratory type device and the wearable measuring device demonstrated a very high degree of correlations with each other. There were no significant differences between two devices’ fat mass measurements in men, in women and in the whole group. When muscle mass data were evaluated, there were no significant differences between two devices’ measurements in men and in the whole group, but there was a significant difference in women (p < .001). When wearable measuring device was compared with laboratory type of bioelectrical impedance device, fat mass measurement results were valid. However, in muscle mass measurements, there was a difference in women. When the wearable bioelectrical impedance measuring device’s reliability was evaluated, it was demonstrated that the device yielded valid results. Therefore, it is concluded that the device will be useful for self-monitoring the body composition.
