Data processing using the Chi square statistical test with α = 0.05 with a confidence level of 95%. The results of the study showed that there was a relationship between family income and the incidence of BGM under five (ρ=0.000), a relationship between eating frequency and the incidence of BGM under five (ρ=0.003), and a relationship between basic immunization status and the incidence of BGM under five (ρ=0.004). The results of this research show a relationship between family income, frequency of eating, basic immunization status and the incidence of BGM in the West Martapura Health Center work area in 2019.
