ABSTRACT

Iodine deficiency is the single most common cause of preventable mental impairment in communities with suboptimal iodine intake. Objective of the present study was to assess in more detail the iodine status and knowledge, attitudes and practice (KAP) relating to use of iodised salt in a remote community in Kotidanga area, Kerema district, Gulf province, Papua New Guinea. This prospective school and community based cross-sectional study was carried out in 2017. Simple random sampling was used to select schools. Multistage sampling was used to randomly select 291 children aged 6 to 12 years. Salt samples were collected for analysis from children’s households as well as a single urine sample of selected children. Salt iodine content and Urinary iodine concentration (UIC) were analysed. A semi-structured FAO questionnaire was used to assess KAP of three different community groups. Only 64% of households had salt on the day of data collection. Mean iodine content in household salt samples was 29.0 ± 19.1 ppm. Iodine content was below 30.0 ppm in 54.8% and below 15.0 ppm in 31.2% of salt samples. Mean per capita discretionary intake of household salt was 2.9 ± 1.8 g/day. Median UIC was 25.5 μg/L and Interquartile Range was 15.0 to 47.5 μg/L; 75.9% (221/291) of the children had UIC below 50.0 μg/L, indicating moderate status iodine nutrition. Median UIC was 34.3μg/L for children in households with salt, compared to 15.5 μg/L for children in households without salt, indicating severe iodine deficiency in the latter group. The three community groups had limited knowledge about importance of using iodised salt and consequences of iodine deficiency on health outcomes. This remote community has limited access to adequately iodised household salt due to high cost, inappropriate packaging, storage and food preparation, resulting in iodine deficiency. Strategies to increase iodine intake are needed.
