Main Findings
Dietary factors have been implicated in the development and severity of
endometriosis.21 To date, most studies related to diet
and endometriosis have focused on incident diagnosis of endometriosis
among women based on dietary intake in adulthood. To our knowledge, this
is the first report that used the Japanese largest birth cohort and
examined the effect of prepregnancy anti-inflammatory diet on obstetric
outcome in women with endometriosis. The obstetric outcome was not
affected by ART. The magnitude of aORs in the present study suggested a
distinctive effect of anti-inflammatory diet on more severe obstetric
outcome, specifically PTB before 34 weeks and LBW <1500 g
among women with endometriosis.
