Poverty could increase a mother's chances of giving birth to a baby with a low birth weight (LBW). Low-income families have trouble supplying food for all family members, including pregnant women. Insufficient food availability at the household level is not limited to food quantity and includes food quality, and the situation in poor households can last for a long time. The study analyzed socioeconomic disparities in rural Indonesia's yield LBW incidence. The study involved mothers (15-49 years) who have given birth in Indonesia's rural areas. The study analyzed 7,786 mothers who received the task as samples. The variables analyzed were LBW, socioeconomic, age, marital, education, employment, and antenatal care. The study used a binary logistic regression test to determine disparities. The study shows the poorest mothers were 1.500 times more likely than the wealthiest mothers to give LBW infants (AOR 1.500; 95% CI 1.499-1.500). Mothers with a more inferior wealth status were 1.531 times more likely than the most prosperous mothers to give birth to LBW infants (AOR 1.531; 95% CI 1.530-1.531). Mothers with a median wealth status were 1.411 times more likely than the richest mothers to give birth to LBW infants (AOR 1.411; 95% CI 1.410-1.412). Wealthier mothers were 1.211 times more likely than the most affluent mothers to give birth to LBW infants (AOR 1.211;). In addition to the socioeconomic status, all control variables, including age group, marital status, education level, employment status, and antenatal care, were also associated with LBW babies incidence. The study concludes that socioeconomic disparities exist in LBW incidence in Indonesia's rural areas.
