Latar Belakang : Masa remaja lanjut (17-21 tahun) terutama perempuan
cenderung mengkonsumsi makanan tanpa lemak untuk mengutamakan kecantikan
tubuhnya, namun tidak sedikit dari mereka makan secara berlebihan sehingga
mengalami obesitas. Status gizi yang di ukur dengan indeks massa tubuh dapat
mempengaruhi sitem hormon dalam tubunya, sehingga berpengaruh pada siklus
menstruasinya. Tujuan penelitian ini untuk mengetahui hubungan indeks massa
tubuh dengan lama siklus menstruasi mahasiswa D III Kebidanan FK UNS.
Metode : Desain penelitian analitik observasional dengan pendekatan cross
sectional. Jumlah sampel 80 responden yang telah di seleksi menggunakan LMMPI
dan teknik purposive sampling. Uji statistik menggunakan spearman
rank.pada ? 5 %.
Hasil : Sebagian besar indeks massa tubuh responden dalam kategori normal
(67,5%) dan sebagian kecil dalam kategori gemuk (7,5%). Sebagian besar lama
siklus menstruasi responden dalam kategori normal (21-35 hari) (60 %). Hasil uji
statistik didapatkan nilai p = 0,002 dan r = 0,343.

Method: This research used the observational analytical research method with
the cross- sectional approach. Its samples was 80 respondent who selected with LMMPI
and purposive sampling technique. The data of research were statistically

Result: Most of the respondent had normal body mass index (67,5%) and a small
portion of the respondent had obese body mass index (7,5%). Most of the

test shows that the p-value = 0.002 and r = 0.343.
