ABSTRACT

Abdominal obesity is an important contributor for health risk factors such as hypertension, diabetes mellitus and hypercholesterolemia. Therefore, the application of a proper method is important prerequisite in performing abdominal obesity assessment. In this study, we applied 3D body scanning technology to measure waist circumference (WC), hip circumference (HC) and waist to hip ratio (WHR) precisely in an effort to improve the current health assessment for abdominal obesity. A total of 200 Malaysian women with sedentary lifestyle, aged between 18 and 60 years participated in this study. Paired t-test was used to determine the differences between the automated (3D body scanner) and manual measurements of WC, HC and WHR. 3D body scanner measurements show that 27% of subjects had mild abdominal obesity (80 - 90 cm) and 34.5% of subjects had severe abdominal obesity (≥90 cm) based on WC cutoff points. Based on WHR cutoff points, 57% of subjects had abdominal obesity (≥0.85) while the remaining were without abdominal obesity (<0.85). Lower percentages of abdominal obesity prevalence were reported for both WC and WHR categories using manual measurements. We also found that in normal BMI category, 8.5% of subjects have mild abdominal obesity based on automated measurements while only 5.5% of subjects were identified on manual measurements. The result of this study indicated that 3D body scanner provided better assessment method as it enables detection of abdominal obesity in more subjects based on WC and WHR categories. Public agencies are encouraged to consider the application of 3D body scanning in health assessment of abdominal obesity.

ABSTRAK

Keobesan abdomen adalah penyumbang penting kepada faktor risiko kesihatan seperti tekanan darah tinggi, kencing manis dan hiperkolesterolemia. Oleh itu, penggunaan kaedah yang betul adalah satu komponen penting dalam menjalankan penilaian keobesan abdomen. Dalam kajian ini, kami menggunakan teknologi pengimbasan badan tiga dimensi (3D) untuk mengukur lilitan pinggang, lilitan pinggul dan nisbah pinggang ke pinggul secara tepat dalam usaha untuk meningkatkan penilaian kesihatan semasa bagi keobesan abdomen. Seramai 200 wanita Malaysia yang berusia antara 18 hingga 60 tahun mengambil bahagian dalam kajian ini. Ujian-t berpasangan digunakan untuk menentukan perbezaan antara automatik (pengimbas badan 3D) dan ukuran manual WC, HC dan WHR. Ukuran pengimbas badan 3D menunjukkan bahawa 27% daripada subjek mempunyai keobesan abdomen sederhana (80 - 90 cm) dan 34.5% daripada subjek mempunyai keobesan abdomen teruk (≥90 cm) berdasarkan kategori WC. Berdasarkan kategori WHR, 57% daripada subjek mempunyai keobesan abdomen (≥0.85) manakala selebihnya adalah tanpa keobesan abdomen (<0.85). Peratusan yang lebih rendah untuk keobesan abdomen dilaporkan bagi kedua-dua kategori WC dan WHR menggunakan ukuran manual. Kami juga mendapati bahawa dalam kategori indeks jisim tubuh (BMI) normal, 8.5% daripada subjek mempunyai keobesan abdomen yang sederhana berdasarkan pengukuran automatik manakala hanya 5.5% daripada subjek berdasarkan ukuran manual. Hasil kajian ini menunjukkan bahawa pengimbas badan 3D menyediakan kaedah penilaian yang lebih baik kerana ia membolehkan pengesanan lebih banyak subjek yang mempunyai keobesan abdomen berdasarkan kategori WC dan WHR. Agensi awam digalakkan untuk mempertimbangkan penggunaan pengimbasan badan 3D dalam penilaian kesihatan untuk keobesan abdomen.
