The design of workstations and workplaces for ergonomics can be challenging when determining anthropometric parameters such as standing height. This study aimed to develop model equations for determining standing height (SH) using regression analysis as an alternative to measurement. The study involved 406 healthy young adults (206 male and 200 female) aged between 19 and 27years from Abeokuta south western Nigeria. Seated-at-shoulder level (SSL), seated-at-knee level (SKL), popliteal height (PH) and standing height (SH) measurements were taken for each participant. Multivariate regression analyses was used to determine the SH with correlation coefficient (R), coefficient of determination (R2) and Standard error of estimation (S.E.E) calculated. Study results showed a strong correlation (P<0.00001) between SH and other anthropometric parameters. It was observed that SKL played a more significant role in determining SH with higher values of R and R2 as well as lower S.E.E in male, female and combined datasets (R: +0.738,+0.578,+0.801), (R2: 0.544, 0.334, 0.642) and (S.E.E: ±4.192, ±4.007, ±4.115). The study concluded that SKL was a better predictor of SH. This research has significant implications for ergonomics design, forensic science investigation and the determination of SH in the young adult population.

ERGONOMİK TASARIM İÇİN OTURMA VE AYAKTA DURUŞLARIN ANTROPOMETRİK MODELLEME İLE ANALİZİ

İş istasyonlarının ve işyerlerinin ergonomiye yönelik tasarımı, ayakta durma yüksekliği gibi antropometrik parametrelerin belirlenmesinde zorlayıcı olabilir. Bu çalışma, ölçüme alternatif olarak regresyon analizi kullanılarak ayakta durma yüksekliğinin (SH) belirlenmesine yönelik model denklemlerin geliştirilmesini amaçlamıştır. Çalışmaya Nijerya'nın güneybatısındaki Abeokuta'dan 19 ila 27 yaşları arasındaki 406 sağlıklı genç yetişkin (206 erkek ve 200 kadın) katıldı. Her katılımcı için omuz hizasında oturma seviyesi (SSL), diz hizasında oturma seviyesi (SKL), popliteal yükseklik (PH) ve ayakta durma yüksekliği (SH) ölçümleri alındı. Korelasyon katsayısı (R), belirleme katsayısı (R2) ve tahminin standart hatası (S.E.E) hesaplanan SH'yi belirlemek için çok değişkenli regresyon analizleri kullanıldı. Çalışma sonuçları SH ile diğer antropometrik parametreler arasında güçlü bir korelasyon (P<0.00001) gösterdi. Erkek, kadın ve kombine veri setlerinde daha yüksek R ve R2 değerleri ve daha düşük S.E.E ile SKL'nin SH'nin belirlenmesinde daha anlamlı rol oynadığı görülmüştür (R: +0.738,+0.578,+0.801), (R2: 0.544, 0,334, 0,642) ve (GD: ±4,192, ±4,007, ±4,115). Çalışma SKL'nin SH'nin daha iyi bir göstergesi olduğu sonucuna vardı. Bu araştırmanın ergonomi tasarımı, adli tıp araştırmaları ve genç yetişkin nüfusta SH'nin belirlenmesi açısından önemli çıkarımları vardır.
