Background: Hypertension (HT) and obesity have both been linked to obstructive sleep apnoea (OSA). Difficulties have been described in identifying patients with OSA in primary care, causing low referral rates to sleep clinics. Increased knowledge about gender-specific characteristics and symptoms may help to identify patients. Aim: The aim was to describe gender differences regarding undiagnosed OSA, self-rated sleep, insomnia and daytime sleepiness in middle-aged primary care patients with HT and different degrees of obesity. Methods: A cross-sectional design was used and 394 patients (52.5% women), mean age 57.8 years (SD 6.7 years), with HT (BP >140/90 mmHg) were included. Clinical examinations, respiratory recordings and self-rated scales regarding OSA symptoms, sleep, insomnia and daytime sleepiness were used. Body mass index (BMI) was classified according to the criteria from the National Institutes of Health. Results: Pre-obesity and obesity classes I and II were seen among 53%, 26% and 8% of the men and 37%, 19% and 14% of the women, respectively. Occurrence of mild, moderate and severe OSA increased significantly across the BMI classes for both genders (p<0.01). Ninety percent of the men and 80% of the women in obesity class II had OSA. Insomnia was prevalent in obese patients. Other clinical variables did not differ between BMI classes or genders. Conclusion: The occurrence of overweight/obesity and OSA was high among both genders. A high BMI might be a convenient clinical marker for healthcare personnel to identify hypertensive patients with possible OSA in need of further evaluation and treatment.
