Abstract

Aim: The research was conducted to determine the effects of nutrition and physical activity on body composition and sleep quality in middle school students. Method: This cross-sectional study was conducted with 396 middle school students and their parents studying in Keçiören district center of Ankara province between June 2021 and March 2022. Data were collected through face-to-face interviews using the “Participant Questionnaire Form”, “Children's Sleeping Habits Questionnaire” and “Children's Physical Activity Questionnaire”. SPSS 23 package program was used to evaluate the data. Results: Of the students included in the study, 53.54% were male, the average body weight was 48.74±11.28 kg, and 53% were of normal weight. Participants' energy and macronutrient intakes, physical activity and sleep scores were found to differ in all body mass index groups (p 0.05). Conclusion: The study concluded that nutrition and physical activity were effective on body composition and sleep quality in middle school students. The importance of nutrition and physical activity education for school-age children was emphasized.

Özet

Amaç: Araştırma, ortaokul öğrencilerinde beslenme ve fiziksel aktivitenin, vücut kompozisyonu ve uyku kalitesi üzerindeki etkisini belirlemek amacıyla gerçekleştirilmiştir. Yöntem: Kesitsel tipte olan bu çalışma, Haziran 2021 ve Mart 2022 tarihleri arasında Ankara ili Keçiören ilçe merkezinde okuyan 396 ortaokul öğrencisi ve ebeveynleri ile yürütülmüştür. Veriler, “Katılımcı Anket Formu”, “Çocuk Uyku Alışkanlıkları Anketi” ve “Çocuk Fiziksel Aktivite Anketi” kullanılarak yüz yüze görüşme yöntemiyle toplanmıştır. Verilerin değerlendirilmesinde SPSS 23.0 paket programı kullanılmıştır. Bulgular: Çalışmaya dahil edilen öğrencilerin %53.54’ü erkek, ortalama vücut ağırlığı 48.74±11.28 kg ve %53’ü normal ağırlıktadır. Katılımcıların enerji ve makro besin öğesi alımları ile, fiziksel aktivite ve uyku puanlarının tüm beden kütle indeksi gruplarında farklılık gösterdiği bulunmuştur (p 0.05). Sonuç: Çalışmada, ortaokul öğrencilerinde beslenme ve fiziksel aktivitenin, vücut kompozisyonu ve uyku kalitesinde etkili olduğu sonucuna ulaşılmıştır. Okul çağı çocuklarına verilecek olan beslenme ve fiziksel aktivite eğitimlerinin önemi vurgulanmıştır.
