Aim: The aim of this study was to examine the factors affecting body composition from prenatal period to adolescence. Method: 392 adolescents with a mean age of 15.65±1.26 years participated in the study. Participants' body mass index (BMI) was 21.37±4.48 kg/m2 in boys, 21.25±3.90 kg/m2 in girls, waist/hip ratio (WHR) was .81±.07 in boys and .74±.05 in girls. Birth weights were determined by Lubchenco's percentile values, and feeding attitudes were determined by nutritional behavior scale. Data analysis was done with IBM SPSS 25.0 package program. Descriptive statistics and Pearson correlation analysis were used to determine the relationships between variables. Results: It was observed that there was a statistically significant correlation between participants 'BMI and WHR and exercising, consuming breast milk, having febrile illness, feeding attitudes and their parents' BMI (p<0.05). Conclusion: As a result, it can be said that consuming breast milk, nutritional attitude and sports activities until adolescence can significantly balance both BMI and waist/hip ratio.
