There is a notable correlation between pregnant women's behavior during the 1st trimester and their adherence to taking folic acid supplements.

Employing an analytical design with a cross-sectional approach, this study aimed to delve into the compliance behavior of pregnant women regarding folic acid intake.

Overall, 197 first-trimester pregnant females, with a sample size of seventy respondents chosen through accidental sampling were included. Utilizing the chi-square test, the examination of data was done.

A key proportion of respondents had an income ranging from Rp1,000,000 to Rp5,000,000, fell within the age range of 20-35 years, were unemployed, and possessed a high school education. Of the pregnant women surveyed, 58.6% displayed adequate behavior, with 85.7% classified as compliant in folic acid consumption. Chi-square test assessment indicated a vital link between the behavior of 1st trimester pregnant females and their adherence to taking folic acid supplements, with a p-value of 0.004, indicating statistical significance (p < 0.05).

There existed a link between the behavior of expectant mothers and their adherence to folic acid use. This highlights the necessity of creating health education initiatives or interventions customized to boost the behavior of pregnant females, thus reinforcing their conformity to folic acid supplementation during their pregnancy journey.
