Evaluation of The Nutrition and Food Safety Knowledge and Behaviour of The Young

Bu çalışma Gazi Üniversitesi'nin farklı fakültelerinde okuyan öğrencilerin beslenme ile gıda güvenliği bilgisi, alışkanlıkları öz yeterlilik ve fiziksel aktivite durumlarını değerlendirmek amacıyla yapılmıştır. Çalışmaya Gazi üniversitesinin sağlık bilimleri (n=140), sosyal bilimler (n=46) ve fen bilimlerinde (n=64) öğrenim gören 68'i erkek, 182'si kız toplam 250 öğrenci dahil edilmiştir. Öğrencilere Turconi ve arkadaşlarının (2003) geliştirdiği toplam 9 bölüm ve 84 sorudan oluşan bir ölçek uygulanmıştır. Veriler SPSS 22.0 programıyla değerlendirilmiştir. Araştırmaya katılan öğrencilerin yaş ortalaması 19.74±1.84 yıldır. Şişmanlığın belirlenmesinde kullanılan beden kütle indeksi (BKİ) değerinin ortalaması erkeklerde ve kızlarda sırasıyla 22.55±2.75 ve 21.25±2.99 kg/m2 'dır. Sağlık bilimlerinde okuyan öğrencilerin beslenme alışkanlığı (BA), sağlıklı/sağlıksız beslenme alışkanlıkları ve besinler (SSBAB), beslenme bilgisi (BB) ve gıda güvenliği bilgisi (GGB) puanları fen ve sosyal bilimlerde okuyan öğrencilerden anlamlı derecede yüksektir. Bütün alt gruplar cinsiyete göre değerlendirildiğinde kız öğrencilerin puanlarının erkeklerden yüksek olduğu ve bu farkın öz yeterlilik haricinde diğer bütün alt gruplarda anlamlı olduğu tespit edilmiştir (p<0.05). Sadece erkeklerin fiziksel aktivite puanları kızlara göre daha yüksektir (p<0.05). Öğrencilerin BKI değerleri artıkça gıda güvenliği bilgisi (GGB) ve sağlıklı/sağlıksız beslenme alışkanlıkları bilgisi (SSBAB) puanlarının düştüğü saptanmıştır (p<0.05). Araştırmada sağlık bilimlerinde okuyan öğrencilerin beslenme bilgi ve alışkanlıklarının diğer bilimlerde okuyan öğrencilerden daha iyi olduğu sonucuna ulaşılmıştırThis study was conducted in order to evaluate the nutrition knowledge, attitude and behaviour states of students studying in different departments of Gazi University. 250 students (68 male and 182 female) were included to this study who were studying in health sciences (n=140), social sciences (n=46) and physical sciences (n=64). Developed by Turconi et al. (2003), a scale of 9 sections and 84 questions was applied to the students. Data were evaluated through SPSS 22.0 program. The average age of all students was19.74&plusmn;1.84 years. The averages of the body mass index (BMI) that is used in defining being overweight were 22.55&plusmn;2.75 and 21.25&plusmn;2.99 kg/m 2 in the males and females respectively than females. Food habits (FH), healthy / unhealthy diet habits and foods (HUDF), nutrition knowledge (NK) and food safety knowledge (FSK) scores of students studying in health science were significantly higher than the students studying in science and social sciences. When all subgroups were evaluated according to sex, it was found that the scores of female students were higher than males and this difference was significant in all other subgroups except for self - efficacy (SE) (p&lt;0.05). Only physical activity scores of males were higher than females (p &lt;0.05). It was observed that among students, those with higher BMI have lower food safety knowledge (FSK) and healthy/unhealthy diet habits knowledge (HUDF) scores (p&lt;0.05) than the others. In the study, it was concluded that the nutrition knowledge and habits of students studying in the health science were better than the students studying in other fields

Validation of predictive equations for resting energy expenditure in children and adolescents with different body mass indexes

Abstract Background Accurate estimation of resting energy expenditure (REE) in children and adolescents is important to establish estimated energy requirements. The objective of this study was to assess the validity of existing equations in literature and a newly developed equation in estimating REE in children and adolescents. Methods 275 participants (148 boys, 127 girls) aged 6–18 years included in the study were classified as normal-weighted, overweight, obese based on BMI z-scores for age according to WHO-2007 growth curves for 5–19 years of age. REEs were measured using an indirect calorimeter, with various equations, and a newly established equation [REE = 505.412+(24.383*FFM);Adjusted R2 = 0.649] were compared with REE measured using Bland-Altman and further validation parameters. Results When the predicted REEs were compared with the measured REEs, the highest prediction accuracy was achieved using the new Eq. (64.8%) and IOM (63.8%) for normal-weight participants, Müller FFM and new Eq. (59.6%) for overweight participants and Lazzer (44.9%) for obese participants. In normal and overweight participants, lowest root mean squared error (RMSE) values were acquired from Schmelzle’s equation (respectively 136.2;159.9 kcal/d), and the highest values were found in Kim’s Eq. (315.2; 295.2 kcal/d respectively). RMSE value of the new equation was 174.7 kcal/d for normal-weight children and adolescents, and 201.9 kcal/d for overweight ones. In obese participants, the lowest RMSE value was obtained from Schmelzle’s Eq. (305.4 kcal/d) and the new Eq. (317.4 kcal/d), while the highest value was obtained from IOM Eq. (439.9 kcal/d). RMSE was higher in obese groups compared to the other BMI groups. Conclusion Indirect-calorimeter is the most suitable method for REE measurement in especially obese children and adolescents. The new equation and Schmelzle’s equation appear to be most accurate equations for normal and overweight children and adolescents
