The prevalence of anemia among pregnant women across all three trimesters was 3.95%, and the prevalence of mild and moderate-to-severe anemia was 1.04% and 2.90%, respectively. Protective factors were living in the northern area (OR\u2009=\u20090.395) and being a member of an ethnic minority (OR\u2009=\u20090.632). The risk factors were residing in rural areas (OR\u2009=\u20091.207), with no more than junior high school education (OR\u2009=\u20091.203), having\u2009\u2265\u20093 gravidities (OR\u2009=\u20091.195) and multiple fetuses (OR\u2009=\u20091.478).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Although the prevalence of anemia among pregnant women across all trimesters in the monitoring area was low, the severity of anemia was high.
