Anthropometric Measurements as a Screening for OSA Among Employees of Philippine Heart Center

Abstract

SESSION TITLE: Sleep 2 SESSION TYPE: Original Investigation Poster PRESENTED ON: Wednesday, November 1, 2017 at 01:30 PM - 02:30 PM PURPOSE: Obesity is a key risk factor for the development of OSA and if undiagnosed and untreated, may lead to serious complications. This study aims to determine the association of anthropometric measurements with risk for OSA, through utilization Berlin Questionnaire, among employees of Philippine Heart Center. METHODS: This is a cross sectional study conducted at the Philippine Heart Center. Anthropometric measurements of 260 employees were obtained and assessed for high risk for OSA through Berlin questionnaire. RESULTS: Subjects who were high risk for OSA based on the Berlin Questionnaire were significantly more likely than those at low risk to have an increased weight 73.9 kg ± 15.1 vs low risk 64.3 kg ± 13.2 (p value <0.001), increased BMI 28.5 ± 4.09 vs low risk 24.5 ± 4.1 (p value <0.001); larger neck circumference 36.9 cm ± 3.7 vs low risk 34.9 cm ± 3.8 (p value 0.0003), larger waist circumference 91.8 cm ± 10.5 vs low risk 82.4 cm ± 12.7 (p value <0.001), greater hip circumference 102.9 cm ± 8.4 vs low risk 95.8 cm ± 10.7 (p value<0.001) and thigh circumference 56.8 cm ± 6.3 vs low risk 53.5 cm ± 8.5 (p value 0.0053). Logistic regression analysis was used after obtaining cut off values for BMI, neck circumference, waist circumference and waist-to-hip ratio. The results showed that increased BMI, waist circumference and waist to hip ratio were statistically significant risk factor for OSA. It is 4.6 times likely to occur if BMI is 28.72 kg/m2 (p value <0.001). Likewise, there was a threefold increase in the probability of OSA if the subject’s waist circumference was >97 cm (p value 0.002) and a twofold more likely of OSA if the subject waist-to-hip ratio >1 in men and >0.85 in women (p value 0.004). Though, neck circumference was close to being statistically significant (p value 0.051). CONCLUSIONS: The result of our study showed that anthropometric indices like BMI, waist circumference, and waist to hip ratio, are significant risk for OSA. On the other hand, our results suggest that neck circumference is not a good predictor of OSA. Thigh circumference was also associated with high risk for OSA which is not included in other studies. CLINICAL IMPLICATIONS: It is important that these anthropometric measurements should be taken on all patients especially if they present with snoring, daytime somnolence, fatigue and hypertension, as they provide cost-effective test in screening OSA prior to polysomnography.
