Notes: *Data expressed as frequency (percentage). **P value was significant if < 0.05 and indicates significance between the different groups. ***P1 compares between underweight and normal weight groups, P2 compares between underwent and overweight groups, P3 compares between underweight and obsess groups, P4 compares between normal and overweight groups, P5 compares between normal and obese groups, P6 compare between overweight and obese groups.
