ABSTRACT
Objective: To determine the association of weight, height, body mass index (BMI) with refractive errors and anterior segment parameters in primary school children. Material and Methods: Complete ophthalmologic examinations of 108 primary school children aged 6-11 years were performed. Central corneal thickness, corneal volume, aqueous depth (AD), keratometry (K) values were obtained with the Sirius topography device. Participants' weight, height, BMI, right eye spherical equivalent (SE), and anterior segment parameters were recorded. Participants were divided into groups as myopic, emmetropic, and hyperopic according to SE values. Data were compared between groups and genders. Results: The mean age of the participants, consisting of 54 boys and 54 girls, was 8.42±1.63 years, BMI 17.33±3.39 kg/m2 , and SE mean 0.18±1.57 diopters (D). There was a significant difference between the groups regarding age, weight, height, SE, and aqueous depth (p<0.05). There was no significant difference between the groups in terms of BMI (p=0.083). There was a negative correlation between SE and age, weight, height, and AD ((r=-0.275, p=0.004; r=-0.262, p=0.006; r=-0.254, p=0.008; r=-0.402, p<0.001, respectively). There was a negative correlation between SE and BMI, but it was not significant (r=-0.193, p=0.046). There was a significant difference between boys and girls in terms of AD and K values (p<0.05). Conclusion: Significant differences were found between the groups in terms of age, weight, height and AD. Our study showed that myopic children had heavier weights, higher heights, and deeper aqueous depth. These findings suggest that school-aged children with rapid height growth and weight gain should be followed more closely regarding refractive errors.

ÖZET
Amaç: İlkokul çocuklarında kilo, boy, beden kitle indeksi (BKİ) ile refraksiyon kusurları ve ön segment parametreleri arasındaki ilişkiyi belirlemektir. Gereç ve Yöntemler: İlkokul çağında 6-11 yaşları arasındaki 108 çocuğun tam oftalmolojik muayeneleri yapıldı. Sirius topografi cihazı ile santral kornea kalınlığı, korneal volüm, aköz derinliği (AD), keratometri (K) değerleri alındı. Katılımcıların kilo, boy, BKİ ile sağ göz sferik ekivalan (SE) ve ön segment parametreleri ölçümleri kaydedildi. SE değerlerine göre katılımcılar miyop, emetrop ve hipermetrop olarak gruplara ayrıldı. Veriler, gruplar ve cinsiyetler arasında karşılaştırıldı. Bulgular: Elli dört erkek ve 54 kız çocuktan oluşan katılımcıların yaş ortalamaları 8,42±1,63 yıl, BKİ ortalaması 17,33±3,39 kg/m2 , SE ortalaması 0,18±1,57 diyoptri idi. Gruplar arasında yaş, kilo, boy, SE, AD açısından anlamlı fark mevcut idi (p<0,05). BKİ açısından gruplar arasında anlamlı fark bulunmadı (p=0,083). SE ile yaş, kilo, boy, AD arasında negatif korelasyon vardı (sırasıyla r=-0,275, p=0,004; r=-0,262, p=0,006; r=-0,254, p=0,008; r=-0,402, p<0,001). SE ile BKİ arasında anlamlı olmamakla birlikte negatif korelasyon mevcut idi (r=-0,193, p=0,046). Erkek ve kız çocuklar arasında AD ve K değerleri açısından anlamlı fark vardı (p<0.05). Sonuç: Gruplar arasında yaş, kilo, boy ve AD açısından anlamlı fark bulundu. Çalışmamızda, miyopik olan çocukların daha ağır kilo, daha uzun boy ve daha derin AD'ye sahip oldukları gösterildi. Bu bulgular, okul çağı döneminde hızlı boy uzaması ve ağırlık artışı olan çocukların refraksiyon kusuru açısından daha yakın takip edilmesi gerektiğini düşündürmektedir.
