About this study
Official title: Is There an Association Between Smartsphone Addiction, Obesity and Functional Capacity in Young Adults?
BACKGROUND: smartphone dependence causes adverse effects on one's lifestyle such as dietary habits and daily routines, resulting in overweight or obesity. Additionally, academic stress also contributes to addictive behaviors, such as smartphone addiction. Research shows that problematic smartphone use is significantly associated with loneliness, low self-esteem, and depression. Poor mental health is also proven to be a risk factor for obesity in young adults.

What is being measured
The primary outcome is the main question the study is designed to answer.
six minute walk test
a simple, self-paced test measuring how far someone can walk in six minutes on a flat surface to assess exercise capacity and cardiorespiratory function,
Measured: 3 months
Secondary outcomes (3)
body shape index
a metric for assessing a person's risk of premature death using their height, weight (mass), and waist circumference.
Measured: 3 months
body shape roundness
Body shape roundness refers to a body type where weight is carried more in the midsection (apple shape) or describes a softer, curvier silhouette, often characterized by rounded shoulders, hips, and chest, with less definition at the waist, contrasting with more angular shapes
Measured: 3 months
smartphone addiction scale
the scale has 10 items, each scored from 1 to 6:
1= strongly disagree 6= strongly agree so the minimum score 10 the maximum score 60 a higher score= worse outcome, because the scale measure the smartphone addiction, and a higher score means strong symptom of addiction.
lower score= better outcome , low score means healthier and controlled smartphone usage
Measured: 3 months
