Abstrak  Setiap individu memiliki pola defekasi berbeda-beda yang dipengaruhi oleh beberapa faktor diantaranya adalah asupan serat. Secara fisiologis serat makanan didefenisikan sebagai karbohidrat yang resisten terhadap enzim hidrolisis saluran pencernaan manusia. Berdasarkan data RISKESDAS 2013, Sumatera Barat menempati urutan ketiga terendah konsumsi serat di seluruh provinsi Indonesia. Tujuan penelitian ini adalah menentukan hubungan antara konsumsi serat dan pola defekasi pada mahasiswi Fakultas Kedokteran Unand angkatan 2012. Ini merupakan penelitian analitik dengan rancangan cross sectional yang dilakukan pada 114 responden. Data primer dikumpulkan dengan wawancara menggunakan kuesioner dan food recall 2x24 jam dan diolah dengan menggunakan Nutrisurvey untuk food recall dan uji statistik chi-square. Hasil analisis univariat menunjukkan bahwa sebagian besar mahasiswi Fakultas Kedokteran Unand angkatan 2012 mengkonsumsi serat rendah dan mengalami resiko terjadinya konstipasi. Hasil analisis bivariat menunjukkan tidak adanya hubungan yang bermakna antara konsumsi serat terhadap pola defekasi dengan nilai p > α (0,408 > 0,05).

Abstract
Each individual has a different pattern of defecation which is influenced by several factors such as intake of fiber. Dietary fiber is defined as carbohydrates that are resistant to hydrolysis enzymes in human digestive. Based on data RISKESDAS 2013, West Sumatra ranks third lowest fiber intake across Indonesian provinces. The objective of this study was to determine the relationship between fiber intake and defecation pattern in the student of the Faculty of Medicine Unand 2012. This was a cross sectional study that conducted on 114 respondents. Primary data was collected by interviews using questionnaires and food recall 2x24 hours and processed using Nutrisurvey for food recall and  chi-square statistic test. Results of univariate analysis showed that most of the student of the Faculty of Medicine Unand 2012 consume low fiber and the risk of experiencing constipation. Results of bivariate analysis showed no significant association between fiber intake and defecation patterns with p-value > α (0.408> 0.05).
