Comparison of the Relationship Between Body Mass Index and Apnea Hypnoea Index in Different Age Groups in Obstructive Sleep Apnea Syndrome Patients

Obesity is a well-defined risk factor for obstructive sleep apnea syndrome (OSAS), but the effects of obesity on OSAS development risk are different in different age groups. The aim of this study was to investigate the relationship between body mass index (BMI) and apnea hypopnea index (AHI) in different age groups and to investigate the effect of obesity on OSAS severity among age groups. Polysomnographic records of patients who underwent whole night polysomnography with OSAS ？pre-diagnosis were retrospectively reviewed. Two hundred thirty-six patients who met the inclusion criteria were divided into 4 groups according to their age range. The groups were composed of patients under the age of 40, between the ages of 41-50, between the ages of 51-60 and over 60. Correlations between BMI and AHI ？of all patients and each group were investigated. There was a statistically significant correlation between BMI and AHI in all groups except patients over 60 years of age. .In accordance with the literature, the effect of obesity on OSAS severity in the elderly group was found to be lower than in the other age groups
