... d trimester in Pekalongan Regency. Sampling using simple random sampling of 75. Data analysis using multiple logistic regression test. The result showed that MUAC is significantly associated with birth weight (p: 0,007;OR: 23), haemoglobin leverls is significantly associated with birth weight (p: 0,007;OR: 25), and weight of pregnant woman is associated with birth weight (p: 0,17;OR: 18).
