Objective: To study the effectiveness of Modified Iodine Consumption Behavior (MICB) Model in Pregnant Women by Integrated
Civil Society Participation. The results were evaluated from the changes in knowledge, iodine consumption behavior, and median
urinary iodine concentration (MUIC) among the intervention group (IG) and control group (CG) of pregnant women (PW) during
pre- and post-intervention period.
Materials and Methods: This participatory action research (PAR) had IG and CG. The authors organized the MICB model by PAR methodology under integrated collaboration of civil society (all sectors) in community via district health board. The present study was conducted in Khon Kaen Province for nine weeks between July and September 2018. The subjects were 88 PW. Forty-seven PW participated in IG and were recruited from antenatal care (ANC) of Chum Phae Hospital. The other 41 PW were assigned as CG and were recruited from ANC of Phu Wiang Hospital. Descriptive statistics, Student’s t-test or Mann-Whitney U test, Chi- squared test or Fisher’s exact test, paired t-test or Wilcoxon signed-rank test, McNemar’s test, adjusted means or ANCOVA, and Student’s t-test or Chi-square test were conducted for analysis.
Results: The authors with civil society and subjects in Chum Phae District had developed the MICB model that resulted in improving knowledge of iodine consumption behavior and MUIC level of IG. The IG significantly gained more knowledge (11.17±2.69 versus 12.45±2.03, p=0.012) when comparing pre- and post-intervention. The IG was found to be using significantly more iodized salt (66.7% versus 89.1%, p=0.013) and iodine supplemented fish sauce (53.1% versus 77.3%, p=0.039) as food condiments when comparing the pre- and post-intervention. The IG received significantly more iodine supplemented multivitamin (ISM) tablets than the CG (100% versus 90.2%, p=0.028) before the intervention. The ISM tablets intake was not different between the two groups. The MUIC level of the IG increased significantly more than those of the CG [386.83 (SE 51.53) versus 254.98 (SE 38.44), p=0.047] comparing pre- and post-intervention.
Conclusion: The MICB model could improve knowledge on iodine consumption behavior and MUIC level of the pregnant women.
