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<0.001). Participants' energy and macronutrient intakes were positively correlated with body weight, height, body mass index and mid-upper arm circumference, and negatively correlated with sleep quality (p<0.05). Physical activity was negatively correlated with body weight, height, body mass index and mid-upper arm circumference, and positively correlated with sleep quality (p<0.05). A negative correlation was found between carbohydrate consumption and neck circumference (p<0.05). Taking confounding factors into account, it was found that physical activity level has negative effects on body composition indicators and positive effects on sleep quality (p<0.05). However, energy, carbohydrate, protein, and fat intake had no effect on body composition and sleep quality (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.

Abstract

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<0.001). Katılımcıların enerji ve makro besin öğesi alımları ile vücut ağırlığı, boy uzunluğu, beden kütle indeksi ve üst orta kol çevresi pozitif korelasyon, uyku kalitesi ile negatif korelasyon göstermiştir (p<0.05). Fiziksel aktivite ile vücut ağırlığı, boy uzunluğu, beden kütle indeksi ve üst orta kol çevresi negatif, uyku kalitesi ile pozitif korelasyon göstermiştir (p<0.05). Karbonhidrat tüketimi ile boyun çevresi arasında ise negatif korelasyon bulunmuştur (p<0.05). Karıştırıcı faktörler dikkate alındığında, fiziksel aktivite düzeyinin vücut kompozisyonu göstergeleri üzerinde negatif, uyku kalitesi üzerinde ise pozitif yönde etkiler gösterdiği bulunmuştur (p<0.05). Enerji, karbonhidrat, protein ve yağ alımlarının ise, vücut kompozisyonu ve uyku kalitesi üzerinde etkisi olmadığı 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.
