A woman gains weight during gestation as part of the normal physiology of pregnancy. Certain women have a high BMI during their pre-pregnancy stage, and during pregnancy, they gain excessive weight, resulting in adverse pregnancy outcomes. Several studies have noted that individuals with lower education or higher household incomes are more prone to being overweight or obese. Therefore, this study aims to investigate the relationship between the socioeconomic status of the family and the prevalence of a history of obesity among pregnant women living in the village of Karangduren, Pakisaji. The total sampling was 25 pregnant with a previous history of overweight or obese BMI. Explanatory research with cross-sectional design used questionnaire, including informed consent. The test is bivariate and descriptive, and the chi-square test was used to obtain the P value. All results from the logistic regression analysis were reported as odds ratios with a corresponding 95% confidence interval. In addition, the study said that their father and mother's education was significantly associated with their BMI status. Family income and FAS are related to BMI status. Familial wealth has no significant correlation with BMI. The study results demonstrate a relationship between family socioeconomic status and maternal weight gain during pregnancy that influences the BMI status. The mother's weight gain is significantly associated with the parents' employment status, income, and the FAS. This study highlights the importance of early intervention to reduce the adverse effects of adult overweight, particularly in families of lower socioeconomic status.
