This research was carried out in Ankara, Turkey, and cross-sectional study. A total of 643 (M = 240, F = 403) volunteers between the ages of 18 and 50 participated in the study. Eating Attitude Test (EAT-26), Young Internet Addiction Test (YIAT), Smartphone Addiction Scale (SAS), and UCLA Loneliness Scales were used in this study. Results As the age of the participants increased, YIAT ( r = − 0.352, p < 0.01), SAS scale ( r = − 0.302, p < 0.01), and UCLA questionnaire scores ( r = − 107, p < 0.01) decreased. When BMI of individuals increas, YIAT ( r = − 0.163, p < 0.01), and SAS scale ( r = − 0.173, p < 0.01) scores decrease. As a result of logistic regression multiple analysis, the odds ratio (OR) and 95% confidence interval (95% CI) values for the risk of abnormal eating attitudes were 1.654 (1.166–2.607) in overweight and 2.257 (1.466–3.477) in smartphone addiction ( p < 0.05).
