obese) entered the study. Anthropometric data and sleep study from
normal weight, overweight and obese subjects are depicted in Table1.</div><div>AHI values were higher in obese (43.3±1.3) than in lean (34.8±3.1) and
overweight subjects (35.5±1.8, P&lt;0.01 ANOVA). Overall, a
direct relationship was evident between AHI and BMI (Figure1). Smokers
were higher in obese group (p&lt;0.05); Systemic Hypertension was
statistically more significant among obese than in leans and overweight
patients (p&lt;0.005). Type 2 diabetes was more represented among
obese patients (p&lt;0.05). Blood total and HDL cholesterol were,
respectively, statistically significant higher and lower in obese
patients (p&lt;0.00001; p&lt;0.0001).</div><div>The cardiovascular risk was strictly related to the obesity
(p&lt;0.00002), while the Epworth Questionnaire score and the
Charlson Co-morbidity Index were respectively statistically higher in
the group of obese individuals (p=0.006, p=0.00002) than in the other 2
Groups.</div><div>In the whole population, the percentage cardiovascular risk was weakly
related with BMI (r=0.33; P&lt;0.001), but not with AHI.</div><div>Figure 1 shows the percentage of cardiovascular risk in the whole
population which was weakly related with BMI (r=0.33;
