Predictive Value of Sagittal Abdominal Diameter for Metabolic Syndrome in Men: A Comparison with Other Anthropometric Measures

Abstract

Aim: To evaluate the diagnostic performance of sagittal abdominal diameter (SAD) for predicting metabolic syndrome (MetS) in men and to compare SAD with other anthropometric measurements. Materials and Methods: This cross-sectional study included 236 male participants. MetS was defined according to NCEP-ATP III criteria. SAD, transverse abdominal diameter (TAD), waist circumference, waist-to-hip ratio, and body mass index (BMI) were assessed. Diagnostic performance was evaluated using ROC analysis. Associations between SAD and metabolic parameters were examined using Spearman correlation. Logistic regression was performed to assess the independent association between SAD and MetS. Results: MetS was identified in 63 participants (26.7%). SAD demonstrated the highest discriminative ability (AUC=0.721, 95% CI: 0.651–0.792, p<0.001). The optimal SAD cut-off was 25.3 cm (sensitivity 52.4%, specificity 80.3%). DeLong testing showed no statistical superiority of SAD over other anthropometric indices. SAD was positively correlated with HOMA-IR, triglycerides, fasting glucose, and hs-CRP, and negatively correlated with HDL-C (all p<0.01). In logistic regression, SAD remained independently associated with MetS after age adjustment (OR=1.27, 95% CI: 1.14–1.42; p<0.001). Conclusion: SAD showed good discriminative performance for MetS in men and remained independently associated with MetS. SAD may serve as a complementary measure to waist circumference and BMI in the clinical assessment of central adiposity.

Erkeklerde Sagital Abdominal Çapın Metabolik Sendromu Öngörmedeki Değeri ve Diğer Antropometrik Ölçümlerle Karşılaştırılması

Abstract

Amaç: Bu çalışmada erkek bireylerde sagittal abdominal çapın (SAD) metabolik sendromu (MetS) öngörmedeki tanısal değerini değerlendirmek ve SAD’in diğer antropometrik ölçümlerle karşılaştırmalı performansını incelemek amaçlandı. Gereç ve Yöntem: Kesitsel gözlemsel bu çalışmaya 236 erkek birey dahil edildi. MetS tanısı NCEP-ATP III kriterlerine göre konuldu. SAD, transvers abdominal çap (TAD), bel çevresi, bel/kalça oranı ve vücut kitle indeksi (VKİ) ölçüldü. Antropometrik parametrelerin tanısal performansı ROC analizi ile değerlendirildi. SAD ile metabolik değişkenler arasındaki ilişkiler Spearman korelasyon analizi ile incelendi. SAD’in MetS ile bağımsız ilişkisi lojistik regresyon ile değerlendirildi. Bulgular: MetS 63 hastada (%26.7) saptandı. SAD MetS’i öngörmede en yüksek ayırt edici güce sahipti (AUC=0.721, %95 GA: 0.651–0.792, p<0.001). SAD için optimal kesim noktası 25.3 cm olup duyarlılık %52.4 ve özgüllük %80.3 idi. DeLong testinde SAD’in diğer ölçümlerden istatistiksel üstünlüğü gösterilemedi. SAD; HOMA-IR, trigliserid, açlık glukozu ve hs-CRP ile pozitif, HDL-C ile negatif korelasyon gösterdi (tümü p<0.01). Lojistik regresyonda SAD yaşdan bağımsız olarak MetS ile ilişkili bulundu (OR=1.27, %95 GA: 1.14–1.42; p<0.001). Sonuç: SAD erkeklerde MetS’i ayırt etmede iyi performans göstermiştir ve MetS ile yaşdan bağımsız ilişkilidir. SAD, santral adipozitenin klinik değerlendirilmesinde bel çevresi ve VKİ’ye tamamlayıcı bir ölçüm olabilir.
