BMI AND ITS IMPACT IN THE INCIDENCE OF COMMON CHRONIC DISEASES.

Background: Overweight prevalence has risen dramatically in recent decades. While it is known that overweight is associated with a wide range of chronic diseases, the cumulative burden of chronic diseases in the population associated with overweight and obesity is not well quantified. Material and Methods: We have analyzed 10 surveys that are suitable to our objectives. Of them two cross-sectional study (follow-up survey), Two epidemiological health surveys, One multistage survey, Two follow-up Surveys and one retrospective study. Results: Screen time was positively related to (BMI) in boys (p=0.002), who spent more time in front of the Computer than girls did (p<0.001). In KSA, the prevalence of Type II DM was 9.7% and 7.1%, obesity was 13.1% and 20.3% and overweight was 27.2% and 25.2% in the total men and women. When the Type II DM Population was separated from the non-diabetics, the prevalence of obesity was 39.3% among diabetic women compared to 18.5% among non-diabetic women, the prevalence of obesity was lower among men compared to the women, and diabetic men had higher prevalence than non-diabetic males (20.7% and 12.1%, respectively). The risk of developing diabetes, hypertension, heart diseases, and stroke increased with severity of overweight among women and men. Conclusion: Obesity considered as a major etiological factor in development of Type II DM in Saudis. High BMI is a determinant of a sedentary lifestyle. During 10 years of follow-up, the incidence of diabetes, hypertension, heart disease, and stroke (men only) increased with degree of overweight in men and women.
