Obese patients experience more severe OSA than non-obese patients

Abstract

To investigate whether previous exposure to obstructive sleep apnea (OSA) increases the risk of obesity in obese and nonobese patients. We identified 24,363 obese patients diagnosed between January 1, 2000, and December 31, 2015, in the Taiwan Longitudinal Health Insurance Database (LHID) 2005 National Health Insurance Research Database; 97,452 sex-, age- and index date-matched nonobese patients were identified from the same database. This study is based on the ninth edition of the International Classification of Sleep Disorders. Multiple logistic regression was used to analyze the previous exposure of obese patients to OSA. P < .05 was considered significant. The average age of 121,815 patients was 44.30 ± 15.64 years old; 42.77% were males, and 57.23% were females. Obese patients were more likely to be exposed to OSA than nonobese patients (adjusted odds ratio [AOR] = 2.927, 95% CI = 1.878–4.194, P < .001), and the more recent the exposure period was, the more severely obese the patient, with a dose-response effect (OSA exposure < 1 year, AOR = 3.895; OSA exposure 1 year, <5 years, AOR = 2.933; OSA exposure 5 years, AOR = 2.486). The probability of OSA exposure in obese patients was 2.927 times that in nonobese patients, and the longer the exposure duration was, the more severe the obesity situation, with a dose-response effect (OSA exposure < 1 year, AOR = 2.251; OSA exposure 1 year, <5 years, AOR = 2.986; OSA exposure 5 years, AOR = 3.452). The risk of obesity in subjects with OSA was found to be significantly higher in this nested case–control study; in particular, a longer exposure to OSA was associated with a higher likelihood of obesity, with a dose-response effect.

Prevalence of Sleep Apnea Syndrome Risk Factors Among Active Drivers and Their Association with Traffic Accidents: A Cross-Sectional Study

“…There exists a complex relationship between obesity and OSA. Studies suggest that the increased storage of fat in specific areas due to obesity may worsen the condition of OSA, and fat deposits in the respiratory tract can expose patients to apnea [2]. Additionally, studies…”

“…These interruptions stem from the upper airway obstruction, attributed to insufficient motor tone in the tongue and/or airway dilator muscles [1]. As the most prevalent sleep-related breathing disorder, OSA poses significant health concerns [2].…”
