Key result
Among 300 healthy obese individuals, 19.7% were found to be at high risk for developing obstructive sleep apnea, with a significantly higher prevalence in males compared to females (p=0.004).
Why the study?
Obstructive sleep apnea leads to multiple complications which may be life-threatening, motivating determination of the frequency of obese individuals at high risk for developing obstructive sleep apnea.
Cross-Sectional (n=300)
No
Nearly 20% of healthy obese individuals in this cohort were found to be at high risk for developing obstructive sleep apnea, highlighting the need for screening in this population.
Supports OSA screening evaluation in obese adults; cross-sectional data leaves causal and predictive questions open.
BACKGROUND & OBJECTIVE: Obstructive sleep apnea (OSA) leads to multiple complications which may be life-threatening. In this study we determined the frequency of obese individuals at high risk for developing (OSA). METHODOLOGY: It was a cross-sectional survey. The study was conducted in the Medicine department of Services hospital, Lahore from February 6, 2016 to August 5, 2016. A sample size of 300 healthy obese individuals (BMI ≥ 30kg/m2) aged between 18-60 years who were accompanying a patient or visiting someone admitted, were enrolled in our study. Informed Verbal consent was obtained before administering a structured, validated questionnaire to the significant obese population; Survey was translated into Urdu for ease. The data were stratified for age, gender and BMI of the patients to control the effect modifiers. Post-stratification Chi-square test was used. A p-value ≤ 0.05 was taken as significant. RESULTS: A total of 300 subjects were enrolled. Mean age was calculated as 41.81±11.98 years, while 161(53.7%) individuals were females and 139(46.3%) were males. The frequency of risk of OSA was low in 241(80.3%) and high in 59(19.7%) of the population. The relationships of OSA with age groups and BMI were insignificant with p-value being 0.867 and 0.790 respectively. CONCLUSION: In this study, a significant population of male obese individuals was found to be at high risk for obstructive sleep apnea.

Atta et al. (2020) conducted a cross-sectional in Obstructive Sleep Apnea (n=300). Obesity (BMI ≥ 30kg/m2) was evaluated on Frequency of high risk for obstructive sleep apnea. Among 300 healthy obese individuals, 19.7% were found to be at high risk for developing obstructive sleep apnea, with a significantly higher prevalence in males compared to females (p=0.004).
