Inflamasi derajat rendah diduga terlibat dalam patogenesis penyakit kronis yangterjadi secara global. Salah satu penanda inflamasi yang kerap digunakan adalahhigh sensitivity C-reactive protein (hsCRP). Asupan serat pangan yang lebih rendahdiduga berperan terhadap kadar hsCRP serum, akan tetapi hasil penelitiansebelumnya masih bervariasi. Studi ini bertujuan untuk mengetahui korelasi antaraasupan serat pangan dengan kadar hsCRP serum pada pekerja sedentari usia 19-49tahun di Jakarta Timur, Indonesia. Studi ini merupakan studi potong lintang pada58 pekerja sedentari yang dilaksanakan pada Bulan Agustus hingga Oktober 2020.Data dasar dikumpulkan memakai kuesioner. Asupan makanan dicatat dengan 3-day food record dan dilakukan pengukuran antropometri untuk mengetahui indeksmassa tubuh (IMT) dan ukuran lingkar pinggang. Pemeriksaan hsCRP serummemakai metode imunoturbidimetri. Analisis untuk menilai korelasi antara asupanserat pangan dan kadar hsCRP serum dilakukan menggunakan uji Spearman jikanilai p<0,05 dianggap bermakna. Mayoritas subjek adalah perempuan, tidakmerokok, dengan aktivitas fisik kurang dan memiliki status gizi normal serta tidakobesitas abdominal. Berdasarkan data asupan makanan didapatkan asupan energi,karbohidrat total, dan serat pangan total berada dibawah rekomendasi AKG. Hanyaasupan lemak total yang sesuai dengan rekomendasi AKG. Asupan serat pangantotal didapatkan sebesar 7,45 g/hari. Nilai hsCRP serum masih dalam batasannormal, yaitu sebesar 0,4 mg/L. Pada analisis bivariat tidak didapatkan korelasiantara asupan serat pangan dengan kadar hsCRP serum (r=0,003, p=0,981). Hasilpenelitian ini tidak mendapatkan adanya korelasi antara asupan serat pangandengan kadar hsCRP serum, namun diketahui asupan serat pangan masih sangatrendah sehingga perlu dilakukan promosi kesehatan untuk meningkatkan asupanserat pangan pada pekerja sedentari.

Low grade inflammation has previously been linked to the global development of

chronic disease. High sensitivity C-reactive protein (hsCRP) is commonly used to

detect inflammation. Low dietary fiber intake was hypothesized to have an effect

on serum hsCRP concentration. To this day, studies on the relationship between

dietary fiber and serum hsCRP have shown inconclusive result. In this study, we

aimed to find a correlation between dietary fiber intake and serum hsCRP on

sedentary worker age 19-49 years old at East Jakarta, Indonesia. This was a cross

sectional study on 58 sedentary workers. This study was conducted in August-

October 2020. Subject’s characteristics was obtained using a questionnaire. Dietary

assessment was conducted using 3-day food record. Anthropometic measurements

included body mass index (BMI) and waist circumference. Serum hsCRP

concentrations were measured using immune turbidimetry. Spearman test was used

to determine correlation between dietary fiber intake and serum hsCRP, with

p<0,05 being significant. Subjects were mostly female, non-smoker, with

inadequate physical activity. A majority of subjects had normal BMI and waist

circumference. Dietary assessment showed subject has inadequate intake of energy,

carbohydrate, and dietary fiber. Only fat intake was adequate in the present study.

Total dietary fiber intake was 7,45 g/day. Median value of serum hsCRP was 0,4

mg/L. There was no correlation between dietary fiber intake and serum hsCRP

(r=0,003, p=0,981). However, this study found that dietary fiber intake was very

low. Thus, education on increasing dietary fiber intake is necessary for sedentary

workers.
