The questionnaire concerned with demographic data, family history of obesity, physical activity level, and the age of introduction of olive oil in the dietary pattern was filled by face to face interview. Anthropometric measurements were obtained by trained team based on a standardized procedure. Using the World Health Organization (WHO) criteria to define BMI categories (WHO, 1999). A BMI result of less than 18.5kg/m2 is considered underweight, 18.5-24.9 kg/m2 is normal, 25-29.9kg/m2 is overweight, while 30kg/m2 and above is obese.

Regarding Waist circumference measure, participants were asked to stand with back straight. Heavy clothing was removed from the waist line. The tape was aligned at the top of the hip bone (iliac crest) parallel with the edge of the last palpable rib (nearly 2 centimeters above the navel). The waist measure was taken at the end of a normal expiration and approximated to the nearest 0.5 cm.
