Tujuan penelitian untuk mengetahui beberapa faktor risiko yang berhubungan dengan lingkar pinggang sebagai indikator obesitas sentral. Desain penelitian yang digunakan cross-sectional dengan sistem random sampling pada 121 responden pegawai kantor pusat PT Wijaya Karya, Jakarta Timur di bulan April-Mei 2012. Data yang dikumpulkan meliputi lingkar pinggang, riwayat genetik, usia, jenis kelamin, indeks massa tubuh (IMT), persen lemak tubuh (PLT), pengeluaran per bulan, aktivitas fisik, dan asupan gizi (asupan energi, protein, lemak, karbohidrat, dan serat). Data dikumpulkan melalui pengukuran lingkar pinggang, persen lemak tubuh, antropometri, kuesioner, dan wawancara FFQ-semiquantirarive. Usia, IMT, PLT, pengeluaran per bulan, asupan energi, lemak, dan karbohidrat berkorelasi signifikan dengan lingkar pinggang (p < 0,05). Perbedaan signifikan juga ditunjukkan antara jenis kelamin dengan lingkar pinggang (p < 0,05). Semakin tinggi usia, IMT, PLT, asupan energi maka semakin besar ukuran lingkar pinggang.

Data were collected through waist measurement, percentage of body fat, anthropometry, questiomlaires, and FFQ-semiquantitative interviews. Age, BMI, BFP, household outcome, intake of energy, fat and carbohydrate were sig11ificantly correlated with waist circumference (p < 0,0S). Also indicated significant differences between the sexes with waist circumference. An increase in age, BMI, BFP, and intake of energy were correlated with a statistically significant in waist circumference gain.
