Background: anemia in pregnancy can harm the health of mothers and children. Lack of hemoglobin level is commonly caused by inadequate intake of foods containing iron, and parasitic infections.

Objective: to analyze the correlation of helminthiasis and iron intake with hemoglobin levels in pregnant women in Public Health Center Kemusu II Boyolali, Jawa Tengah, Indonesia.

Methods: this study uses a cross sectional design. The samples of this research are 164 pregnant women who are in six-nine months. The samples are recruited using simple random sampling technique. The hemoglobin level are acquired by measuring the respondents' hemoglobin level using Cyanmethemoglobin tool. The iron intake are obtained by interviewing the subjects' meal intake using the Semi Quantitative Food Frequency Questionnaire (SQ-FFQ) form for at least three months. Pearson product moment will be applied to analyze the correlation.

Result: the study find that 34.1% of the subjects suffer from iron intake deficiency; 12.2% subjects are infected by Ascaris lumbricoides; and 41.5% of subjects suffer from anemia. There is a correlation between helminthiasis and hemoglobin level (p=0.005) and there is a correlation between iron intake and hemoglobin level of pregnant women (p=0.007).

Conclusion: From the research finding, it could be concluded that the implication of policy result of community nutrition program is still needed as the effort to prevent the helminthiasis and reduce the prevalence of anemia in the pregnant women, and improve their iron intake through iron supplementation followed by nutrition education.

Keywords: helminthiasis, iron intake, hemoglobin level.
