This study aimed to describes the anemic incidence in the third trimester of pregnant women at Puskesmas Tegalrejo Yogyakarta. This research was a descriptive study that used a retrospective time approach. A total of 212 pregnant women in the third trimester met the inclusion criteria, which was pregnant women in the third trimester who had their pregnancy checked at the Puskesmas Tegalrejo Yogyakarta. The research tool used was a data collection sheet. Data was analyzed in proportion and percentage then using Chi Square analysis to get the correlational value (p<0.05). Odds Ratio for Cohort value toward anemic status also was analyzed. The incidence rate of anemia (Hb <11gr%) occurred in 44 (20.8%) mothers aged <20 years and> 35 years, 58 (27.4%) mothers with gestational age <37 weeks, 137 (64.6%) mothers with> 4 parity, with a pregnancy interval of <24 months from the last child, as many as 141 (66.5%) mothers and 110 (51.9%) mothers with nutritional status based on upper arm circumference <23.5cm. These factors are considered risk factors for causing anemia in pregnant women. Correlation test using Chi Square is known to show p <0.05 for all variables. The highest risk for Anemic Incidence was known to be indicated by the Pregnancy Interval factor, <24 months (p <0.001; OR 9,512) followed by parity >4 (p <0.001; OR 6,679). Keywords: anemia, pregnant women INTRODUCTION Reducing the Maternal Mortality Rate (MMR) to 70 per 100,000 live births (KH) by 2030 is one of the Sustainable Development Goals (SDGs), which is a sustainable development effort that becomes a reference in the development and negotiation framework of countries in the world. This output is certainly getting lower when compared to the 2015 MDGs target of reducing MMR to 102 per 100,000 KH (Nur, 2019). That target is an approach following the facts that, estimated that worldwide more than 585 mothers die each year during pregnancy and childbirth, anemia is one of the indirect causes of death for pregnant women and childbirth.
