ABSTRAKLatar belakang: Kehilangan gigi merupakan penyakit utama rongga mulut.
Berkurangnya jumlah gigi akan menurunkan kemampuan mastikasi dan
menyebabkan pemilihan makanan yang berujung pada kurangnya asupan nutrisi.
Nutrisi yang buruk dapat berakibat pada perubahan indeks massa tubuh (IMT).
Tujuan: Menganalisis hubungan antara kemampuan mastikasi dan IMT. Metode:
Penelitian dilakukan dengan metode potong lintang pada 129 subjek berusia 34-80
tahun. Subjek diukur tinggi badan dan berat badannya, diwawancara menggunakan
kuisioner kemampuan mastikasi dan dilakukan pemeriksaan intra oral. Analisis Chi
Square digunakan untuk mengetahui hubungan antara kemampuan mastikasi,
kehilangan gigi, pemakaian gigi tiruan, usia, jenis kelamin dan status ekonomi
dengan IMT. Hasil penelitian: Kemampuan mastikasi tidak memiliki hubungan
yang bermakna dengan IMT (p=0,963). Ditemukan hubungan yang bermakna antara
usia dengan IMT (p=0,028). Kesimpulan: Usia mempengaruhi indeks massa tubuh.
ABSTRACTBackground: Tooth loss is a major disease of the oral cavity. The primary function
of teeth is mastication. Decreasing number of teeth will reduce the masticatory
performance and causing food selection which leads to lack of nutrition. Poor
nutrition resulted changes in body mass index (BMI). Objective: To analyze the
relationship between masticatory performance and BMI. Methods: The study was
conducted with a cross-sectional method on 129 subjects age 34-80 years. Subject
was measured their height and weight, then interviewed using a questionnaire about
masticatory performance and intra oral examination was conducted. Chi square was
used to analyse the relation between the masticatory performance, tooth loss, denture
wearer, age, gender, economic status with BMI. Result: Masticatory performance
was not significantly associated with BMI (p = 0.963). A significant association was
found between age and BMI (p = 0.028). Conclusion: Age affects the body mass
index.
