Disturbances at an early stage, provide immediate intervention and prevent death. During PNC visits, mothers will also receive supplements such as folic acid and iron that help in preserving their healthy condition. This study aims to identify the association between PNC coverage and distribution of iron supplements with cases of non-infectious disease in pregnant mothers in Narmada PHC and identify factors associated with PNC coverage and distribution of iron supplements. A mixed of quantitative and qualitative data analysis were used in this study. Data of K1, K4, Fe1, Fe3, anemia, chronic energy deficiency (CED), and pregnancy hypertension were collected from 2020 PWS-KIA data from all eleven villages in Narmada District. We also conducted interviews with key informants such as midwives and nurses actively involved in the PHC's mother and child program. The findings show that the lowest coverage of K1 and K4 was in Tanak Beak village, Dasan Tereng had the lowest Fe1 coverage, and Gerimax Indah had the least Fe3 coverage. On the other hand, Batu Kuta had the highest K1 coverage while Mekar sari had the highest coverage of K4, Fe1 and Fe3. The village with the highest prevalence of anemia was Gerimax Indah, Mekarsari had the highest number of mothers with CED, and Nyurlembang had the highest prevalence of pregnancy hypertension. Analysis with Spearman's correlation showed a negative correlation between coverage of PNC and iron distribution with anemia in pregnancy. Study findings also inferred a negative correlation between coverage of PNC and pregnancy hypertension. Meanwhile, a positive correlation existed between PNC coverage and iron distribution with CED and between iron distribution with pregnancy hypertension. We found significant association between K1 to K4, Fe1 to Fe3, PNC coverage with total cases and between Fe3 coverage with CED. From qualitative analysis we found factors contributing to the low coverage of PNC and distribution of iron supplements are lack of compliance from mothers, under-reporting (e.g. still births, pregnancies), local belief system (myths), and general misconceptions due to low education. Our study suggested that PNC and iron supplements help in improving mothers' health during pregnancy. It is also suggested that a boost in understanding from mothers and the local community is needed to keep the mothers comply with healthy behaviors such as regularly attend recommended PNC sessions and diligently take iron supplements.
