“…Even though a higher prevalence of sleep apnoea has been reported in an Australian study, 37 the prevalence of SDB was high compared with most other population based studies. This is partly explained by the fact that the population was biased by oversampling of hypertensive subjects and, as the non-hypertensive controls were matched for BMI, there was also an oversampling of overweight subjects in the control group.…”

Background: Several studies have reported an association between sleep disordered breathing (SDB) and hypertension (HT) but there is still a debate as to whether this is an effect of confounders. Some researchers have found an age dependent relationship between SDB and HT with higher risk at lower ages. A case-control study was performed in hypertensive men and non-hypertensive male controls matched for age and body mass index to assess whether there is an independent association between SDB and HT. If so, we further wanted to investigate whether this effect is age dependent. Methods: An overnight sleep study was performed in a population based, age stratified sample of 102 hypertensive men aged 43-82 years and 102 non-hypertensive controls. Results: Hypertensive subjects had a significantly higher prevalence of SDB than non-hypertensive subjects (apnoea-hypopnoea index (AHI): 10.8 v 7.3; desaturation index (DI): 8.5 v 5.2; AHI >10: 37% v 24%, p<0.05; DI >10: 29% v 12%; lowest desaturation: mean (SD) 81.9 (7.3) v 84.7 (6.1), p<0.01). After adjusting for neck circumference and physical inactivity, DI >10 and lowest desaturation were still independent predictors of HT with adjusted odds ratios of 2.3 (95% CI 1.0 to 5.3) and 0.94 (95% CI 0.89 to 0.99), respectively. When the subjects were split into two groups according to age (<60 and >60 years), the influence of DI >10 on HT was strongest in the younger men (adjusted OR 4.3 (95% CI 1.0 to 19.3 v 2.1 (95% CI 0.7 to 6.5)) and the association between minimum oxygen saturation (SaO 2 ) and HT reached statistical significance in the younger men only. Conclusion: SDB is more prevalent in men with HT than in controls. DI >10 and lowest desaturation are independent predictors of HT irrespective of confounders. The results indicate that the influence of SDB on HT is more pronounced in younger and middle aged men than in those above 60 years.

“…Patients with age less than 30 and more than 60, those with history of surgery to the nose, nasopharynx or throat and those with neurological problems were excluded. Based on the previous studies, the prevalence of OSAS was found to be 3.6% 5 with 5% level of significance and 0.6% precision, a sample of 40 patients were recruited for the study. A detailed history and general examination which included measurement of height, weight, chest, neck, waist and hip circumference were taken.…”

“…The physiopathology of OSAHS is multifactorial and derives in part from upper airway or craniofacial anatomical alterations associated with alterations of the neuromuscular pharynx (2). The highest prevalence is among males and in the 40-and 50-year-old groups (3). Other factors such as obesity and upper airway or craniofacial anatomical alterations have also been correlated with the disease (2).…”

The physiopathology of obstructive sleep apnea-hypopnea syndrome (OSAHS) is multifactorial and obesity has been shown to be one of the main factors correlated with its occurrence. In obese patients with anatomical alterations of the upper airways it is often difficult to predict success for surgical correction since obesity is a limiting factor. Therefore, the aim of the present study was to evaluate the results of tonsillectomy in a specific group of patients, i.e., obese OSAHS patients with tonsil hypertrophy. Seven OSAHS patients with moderate obesity with obstructive palatine tonsil hypertrophy were submitted to tonsillectomy. All patients were submitted to pre-and postoperative appraisal of body mass index, otorhinolaryngology examination and polysomnography. Patients' average age was 36.4 ± 10.3 years and average preoperative body mass index was 36.6 ± 6.3 kg/m 2 . Postoperative weight did not differ significantly from preoperative weight (P = 0.27). Average preoperative apnea and hypopnea index (AHI) was 81 ± 26/h and postoperative AHI was 23 ± 18/h (P = 0.0005). Average preoperative minimum oxyhemoglobin saturation (SaO 2 min) was 69 ± 14% and the postoperative value was 83 ± 3% (P = 0.038). In relation to AHI, 6 (86%) of the 7 patients studied showed a reduction of 50% in relation to preoperative level and of these, 4 (57%) presented AHI of less than 20%. Only one patient presented a reduction of less than 50% in AHI, but even so showed improved SaO 2 min. Tonsillectomy treatment for OSAHS in obese patients with obstructive palatine tonsil hypertrophy caused a significant reduction in AHI, with improvement in SaO 2 min. This procedure could be eventually considered as an option of treatment for obese OSAHS patients with significant tonsil hypertrophy when continuous positive air pressure therapy is not possible as the first choice of treatment.
