Summary

Main objective: To assess the effect of the daily physical activity promotion with a pedometer during 12 months on the apnea-hypopnea index (AHI) in patients with mild to moderate obstructive sleep apnea (OSA).

Study patients. Subjects 30-80 years old with diagnosis of mild-moderate OSA (AHI: 5-30 and predominance of obstructive events \[\>80%)\].

Design. Randomized, parallel and open-label clinical trial, controlled with conventional treatment.

Intervention: Patients will be randomized (1:1) to control group \[treatment and follow-up according to conventional clinical practice\] or intervention group \[in addition to conventional treatment and follow-up, the patients will receive a pedometer to measure the number of steps walked daily. Based on the cumulative step count for each day and the mean value since the last visit, patients will receive a task to increase their steps per day by the next appointment according to the next protocol (\<6000 steps/day: increase by 3000 steps/day; 6000 - 10000 steps/day: reach 10000 steps/day; and \> 10000 steps/day: maintain or increase steps).

Measurements. At , 12, 24 and 52 weeks of randomization, the following determinations will be made: anthropometric characteristics; clinical evaluation (smoking history, sleep symptoms, comorbidities, current medication); questionnaires (ESS, FOSQ, SF-12, EuroQoL and iPAZ); heart rate and blood pressure; analytical determinations (HbA1c, HOMA index, cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, homocysteine, NT-proBNP and hsCRP); plasmatic biomarkers (8-isoprostane, IL1beta, IL6, IL8 and TNFalpha); and evaluation of daily physical activity using an accelerometer.

BEHAVIORAL

Promotion of daily physical activity with a pedometer

Patients will receive an ONwalk 100 pedometer (GEONAUTE, France) and will be instructed how to use it. They will be encouraged to be more active by using the pedometer to measure the number of steps walked daily and to record this in a diary, together with any information related to their clinical condition. Based on the cumulative step count for each day and the mean value since the last visit, patients will receive a task to increase their steps per day by the next appointment according to the next protocol: * \<6000 steps/day: increase by 3000 steps/day * 6000 - 10000 steps/day: reach 10000 steps/day * \> 10000 steps/day: maintain or increase steps

OTHER

Conventional treatment

Treatment and follow-up according to conventional clinical practice (SEPAR guidelines), including standard recommendations on healthy habits and lifestyle.
