Türk Çocuklarında Baş Çevresinin Normal Değerleri

Genel Bilgiler: Baş çevresi ölçümü, beyin hacmi ve ilişkili olabilecek sorunları belirlemede hızlı, basit, ucuz, non- invaziv ve güvenilir bir yöntemdir ve olası medikal problem risklerinin tanınma ve takip sürecinde bilgi sağlar. Baş çevresi büyümesi toplumlar arasında ve cinsiyete göre değişkenlik gösterebilir. Yöntemler: Türkiye’de yaşayan 0-18 yaş arası çocuklar için baş çevresi büyüme eğrileri oluşturmak hedeflendi. Ölçümler aynı kişi tarafından kalibre edilmiş, esnemeyen bir mezura kullanılarak yapılmıştı. Ayrıca ebeveynlerden çocukların büyümesini etkileyebilecek değişkenleri içeren bir anket doldurmaları istendi. Bulgular: Veri analizi, çocukların baş çevresi ile ailelerinde baş çevresi büyük/küçük olan birinin olup olmadığı, ailelerinin ortalama aylık geliri, ebeveynin eğitim düzeyi arasında bir ilişki olmadığını göstermiştir. Erkek çocuklar için çocuğun okul başarısı, doğum ağırlığı, beslenmesi, annenin sigara içmesi bağımsız değişkenler olarak belirlenmiştir ve alfa değeri 0,05 idi. Kızlar için doğum ağırlığı ve beslenme şekli bağımsız değişkenlerdi ve alfa değeri 0,05 idi. Doğum ağırlığındaki bir gram artışın, her iki cinsiyette baş çevresinde 0,001 cm'lik bir artışa neden olduğu gösterildi. Ayrıca her iki cinsiyet için 0-18 yaş arası tüm çocukları kapsayacak şekilde baş çevresi büyüme eğrileri oluşturuldu. Sonuçlar: Güncel ve cinsiyete özgü veriler ile oluşturulmuş baş çevresi büyüme eğrilerinin kullanılmasını gerektiğini önermekteyiz. Bu yeni değerler çocuk takibinde daha etkin olarak kullanılabilecektir.

Norm Values of Head Circumference in Turkish Children

Objective: Measuring head circumference is a quick, simple, cheap, noninvasive and reliable procedure for determining underlying brain size and provides information about risk for medical problems. Growth percentages of head vary from one community to another. Methods: We aim to create head circumference growth curves for children aged 0-18 years in Turkish community. Measurements were performed by same person using a rigid and calibrated tape meter. In addition, the parents were asked to fill out a questionnaire with variables that could affect children's growth. Results: Data analysis has shown that there is no relationship between the children's head circumference and whether there exists someone with a large/small head circumference in their families, or the average monthly income of their families and the parent’s education level. Only the independent variables child’s school performance, birth weight, nutrition, smoking are significantly effective on the HC measures of boys at alpha=0.05 level. For girls, only the independent variables birth weight and nutrition form are significantly important in explaining the variability of HC at the level of alpha=0.05. One gram increase in birth weight causes a 0.001 cm increase in the HC of both genders. In addition, head circumference growth curves were created for both genders to include all children aged 0-18. Conclusions: Our study offers recent and gender-specific head circumference norms. These new values can be used more effectively in child follow-up.
