Background: To reduce maternal mortality, the Indonesian government campaigned for a health promotion program based on the family approach, namely “Suami Siaga” (Husband Alert). Study aims to analyze the effect of socioeconomic on the husband's involvement in ANC in rural Indonesia.Methods: The study employed data from the 2017 IDHS. Samples of 7,156 respondents were obtained. Besides the socioeconomic, other variables analyzed in this study were age, education, occupation, and parity. The final stage was employed binary logistic regression.Results: Families with the poorer socioeconomic status, the possibility of husbands being involved in ANC was 2.154 times compared to the poorest. Families with the middle socioeconomic status were more likely to have their husbands involved in ANC 2.785 times compared to the poorest. Families with a richer socioeconomic status were more likely to have their husbands involved in ANC 2.901 times compared to the poorest. Meanwhile, families with poorer socioeconomic status, the possibility of their husbands being involved in ANC was 5.299 times compared to the poorest. The results of this analysis inform that all socioeconomic statuses have a higher likelihood of husband involvement in ANC than the poorest families. The better the socioeconomic, the higher the possibility of the husband to be involved in ANC. Apart from socioeconomic, 3 other variables were also found as determinants of the husband's involvement in ANC in rural Indonesia, namely education, occupation, and parity.Conclusions: The socioeconomic status was a determinant of the husband's involvement in ANC in rural Indonesia.
