The Influence of Pregnancy Classes on Pregnant Women's Knowledge of Danger Signs of Pregnancy

The maternal mortality rate in Indonesia remains high, reaching 305 per 100,000 live births in 2021, with one contributing factor being the lack of maternal knowledge regarding pregnancy danger signs. Prenatal classes are considered a strategic intervention to improve pregnant women’s understanding of critical warning signs such as bleeding, severe abdominal pain, and infection symptoms. This study aims to analyze the influence of pregnancy classes on pregnant women’s knowledge of danger signs. The research employed a quantitative design with a cross-sectional approach involving 30 pregnant women selected through purposive sampling at several community health centers. Data were collected using validated and reliable questionnaires, with measurements conducted before (pre-test) and after (post-test) participants attended at least three prenatal classes. Data analysis used descriptive statistics and the Wilcoxon Signed Rank Test with SPSS. The results showed that most respondents were aged 20–35 years (63.3%), had a high school education (36.7%), were housewives (60.0%), and multigravida (56.7%). Before the intervention, 50% had poor knowledge and only 20% had good knowledge. After attending prenatal classes, 63.3% achieved good knowledge, while only 10% remained in the poor category. The Wilcoxon test showed a significant difference (p = 0.000). Thus, prenatal classes effectively improve knowledge and support early detection of complications, potentially reducing maternal and infant mortality rates.
