Obesity in UAE

Obesity has become a major problem in the UAE. Over 60% of Emirati nationals are overweight. This is a difficult problem with many serious effects on the individual and country. The biggest effect is on the individual. First of all, being overweight has health risks. Obesity can lead to heart disease, diabetes, and other conditions. A study was conducted to determine the factors that might affect the obesity. A random sample of 617 individuals was selected from different emirates and for each individual a number of variables are measured. Among these variables are given below:

Emirate: 1=Abu Dhabi, 2=Dubai, 3=Sharjah, 4=Ajman, 5=Al-Fujirah, 6=Ras AlKhaimah, and 7=Umm Al-qwain

Education: 1=less than high school, 2=high school, and 3=College

Gender: 1= Male, and 2=Female

Marital status: 1=Married, and 2=Unmarried

Weight: Weight in kg.

Height: Height in meter.

BMI: Body mass index BMI =

BMI group: 1=Underweight, 2=Normal weight, 3=Overweight, and 4=Obese
