Effect of Lifestyle Modifications on Polysomnography in Obstructive Sleep Apnea

Area of Science:

• Sleep Medicine
• Cardiorespiratory Physiology

Background:

• Obstructive sleep apnea (OSA) is a condition often overlooked in treatment plans.
• Lifestyle modifications (LSM) are crucial but underutilized components of OSA management.
• This study investigates the impact of a structured LSM program on OSA patients.

Purpose of the Study:

• To evaluate the effectiveness of a customized lifestyle modification program for obstructive sleep apnea (OSA).
• To assess the impact of this program on polysomnographic parameters and body mass index (BMI).

Main Methods:

• A prospective study involving 56 OSA patients diagnosed via polysomnography (PSG).
• Patients were randomized into two groups: Group A (customized diet, counseling, follow-up) and Group B (general weight loss advice).
• Both groups received lifestyle modification advice including diet and physical activity; outcomes were measured after 6 months using repeat PSG and BMI analysis.

Main Results:

• Group A showed significant improvements in Apnea-Hypopnea Index (AHI) and time with oxygen saturation below 90% (cT90), along with better mean lowest saturation (LSAT).
• Group B demonstrated improvements only in LSAT and cT90.
• The study analyzed data from 54 subjects, with 89.28% in Group A experiencing significant positive changes.

Conclusions:

• A tailored lifestyle modification program, incorporating a specific diet, physical activity, and regular counseling, yields superior outcomes in OSA management.
• This customized approach can serve as an effective adjuvant therapy for obstructive sleep apnea.
• Structured lifestyle interventions are key to improving polysomnographic measures in OSA patients.
