Background. The pregnancy class program aims to help pregnant women maintain their health conditions and prevent complications during pregnancy. Several factors may influence participation in this program, including characteristics and knowledge of pregnant women. Objective. The purpose of this study was to determine the correlation between the characteristics and knowledge of pregnant women and their participation in the pregnancy class at the public health centre Banjarangkan II. Method. This study employed a correlational analytical design with a cross-sectional approach. The population consisted of all pregnant women in the working area of the public health centre Banjarangkan II. In this study, 73 pregnant women were selected as a sample using a total sampling technique. Data were collected using a structured questionnaire and analysed using Spearman’s Rho statistical test. Results. The findings on statistical results indicated a significant correlation between the pregnant women’s occupation (p = 0.030) and knowledge on pregnancy class (p < 0.001) with the participation of pregnant women in the pregnancy class. However, no significant correlation was found between the age (p = 0.169) and education level (p = 0.857) of pregnant women who participated in the program. Conclusion. Pregnant women’s participation in pregnancy classes is significantly influenced by occupation and knowledge of pregnant women. Educational outreach through integrated health activities at the health service integrated post (posyandu) is recommended to improve awareness about the benefits of joining the pregnancy class.
