ADLN - PERPUSTAKAAN UNIVERSITAS AIRLANGGA ABSTRAK Konstipasi merupakan masalah yang sering dikaitkan dengan kurangnya asupan serat dan asupan cairan. Selain itu, faktor lain yang ikut mempengaruhi terjadinya konstipasi yaitu kehamilan karena pada wanita hamil terjadi peningkatan hormon progesteron yang menyebabkan relaksasi otot polos sehingga peristaltik usus melambat serta pengaruh dari konsumsi zat besi, terutama pada kehamilan wanita hamil trimester ketiga sampai 3 bulan pertama setelah melahirkan. Jenis penelitian ini adalah penelitian observasional dengan pendekatan Cross Sectional. Sampel pada penelitian ini adalah ibu hamil trimester III yang mengikuti penelitian POGI sebanyak 33 orang. Teknik sampling menggunakan systemic random sampling. Pengumpulan data dilakukan dengan wawancara responden dan kunjungan rumah setiap hari untuk mengumpulkan catatan harian (3D-fluid diary) asupan cairan selama 3 hari berturut-turut dan recall 3x24 jam asupan makanan. Analisis data dilakukan secara univariat dan bivariat menggunakan uji Wilcoxon signed rank test. Hasil analisis menunjukkan asupan serat ibu hamil trimester III dan ibu pasca melahirkan diperoleh nilai p=0,317 (α>0,05), Asupan cairan ibu hamil trimester III dan ibu pasca melahirkan diperoleh nilai p=0,655 (α>0,05) dan Konstipasi ibu hamil trimester III dan ibu pasca melahirkan diperoleh nilai p=0,157 (α>0,05). Berdasarkan analisis ketiga variabel yang diteliti menunjukkan bahwa p>0,05 berarti tidak ada perbedaan asupan serat, asupan cairan dan konstipasi pada ibu hamil trimester III dan ibu pasca melahirkan. Tidak ada perbedaan asupan serat, asupan cairan dan konstipasi pada ibu hamil trimester III dan ibu pasca melahirkan. Selain asupan serat dan asupan cairan terdapat banyak faktor yang mempengaruhi konstipasi seperti hormon, perubahan anatomi dan asupan makanan, maka diperlukan pemberian health education yang efektif dan pemberian menu nutrisi tinggi serat sehingga dapat mencegah terjadinya konstipasi terutama pada wanita hamil dan ibu pasca melahirkan.

MUAWANAH ADLN - PERPUSTAKAAN UNIVERSITAS AIRLANGGA ABSTRACT Constipation is a common problem associated with inadequate intake of fiber and fluid intake. In addition, other factors that influence the occurrence of constipation is a pregnancy because during this period progesterone hormone is increasing therefore slowing intestinal peristalsis and the effect of iron supplementation, particulary in the third trimester of pregnancy pregnant women up to the first 3 months after childbirth. This type of research was observational research with cross sectional approach. Sample in this study were thirty-three (33) of the third trimester pregnant women who follow the research POGI. Sampling technique using systemic random sampling. Data was collected by interviewing respondents and home visits every day to collect the diaries (3D-fluid diary) of fluid intake for 3 consecutive days and 3x 24-hour recall food intake. Data analysis was performed using univariate and bivariate using the Wilcoxon sign test. The Result showed that fiber intake of third trimester pregnant women and postpartum mothers obtained value of p = 0.317 (α> 0.05), fluid intake third trimester pregnant women and postpartum mothers obtained value p = 0.655 (α> 0.05) and constipation third trimester pregnant women and postpartum mothers obtained value of p = 0.157 (α> 0.05). Based on the analysis of the three variables studied showed that p> 0.05 means there were no difference in fiber intake, fluid intake and constipation in third trimester pregnant women and postpartum mothers. It concluded there were no difference in fiber intake, fluid intake and constipation in third trimester pregnant women and postpartum mothers that in addition to the intake of fiber and fluid intake, there are still many factors that affect constipation such as hormonal, anatomical changes and food intake. Thus, it required effective health education and provision of nutrients menu high in fiber that can prevent constipation, especially in pregnant women and postpartum mothers.
