Link Between Smartphone-Related Anxiety (Nomophobia) and Stress, Body Image, and Food Addiction in University Students

An Investigation of the Relationships Between Nomophobia Levels and Stress, Body Image and Food Addiction Among University Students

Observational Bahçeşehir University · NCT07518056

This project will test whether higher smartphone-related anxiety (nomophobia) is linked to more perceived stress, stronger food-addiction symptoms, and distorted body image in 18–30-year-old undergraduate students.

What this trial studies

Undergraduate students aged 18–30 at Bahçeşehir University will complete questionnaires including the Nomophobia Questionnaire (NMP-Q), Perceived Stress Scale (PSS-10), Yale Food Addiction Scale (YFAS), and the Stunkard Figure Rating Scale (FRS), along with a sociodemographic form and daily screen-time tracking. Objective body composition data (body weight, body fat percentage, skeletal muscle mass) will be collected using the InBody 270 via bioelectrical impedance analysis after standardized preparation, and waist and hip circumferences will be measured manually to compute BMI and waist-to-hip ratio. The study will compare subjective perceptions of body image and eating behavior with objective anthropometric measures to explore relationships with nomophobia levels. Data analysis will focus on correlations between nomophobia and perceived stress, food addiction scores, and body image distortion, and on how objective measures relate to subjective body-image perceptions.

Who should consider this trial

Good fit: Ideal participants are active smartphone-using undergraduate students aged 18–30 at Bahçeşehir University who can give informed consent, are not pregnant, do not have pacemakers or metallic prostheses, and have no diagnosed metabolic or acute/chronic psychiatric conditions affecting eating behavior.

Not a fit: People with current diagnosed eating disorders, severe psychiatric diagnoses or ongoing psychiatric medication use, recent corticosteroid use, pregnancy or breastfeeding, or those unwilling to complete the questionnaires and body-composition protocol are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the findings could highlight smartphone-related anxiety as a modifiable factor associated with stress, eating-related behaviors, and body-image distortion, informing prevention or support efforts for students.

How similar studies have performed: Previous observational research has reported correlations between smartphone dependence and higher stress or disordered eating, so this study builds on existing correlational evidence rather than testing a new treatment.
