Iodine deficiency in primary school children and knowledge of iodine deficiency and iodized salt among caretakers in Hawassa Town: Southern Ethiopia

Background: More than two billion individuals worldwide have inadequate iodine intake and the adverse consequences of iodine deficiency are widely observed.Objective: To assess the iodine status of primary school children and the knowledge of iodine deficiency disorders among their caretakers.Methods: A cross-sectional study was conducted in Hawassa Town, Southern Ethiopia. The study participants were school children (n=116) aged 7-9 years. A two-stage sampling method was used to select participants. Goiter and urinary iodine concentration were measured in the children to evaluate their iodine status. Socioeconomic characteristics, dietary patterns and caretaker knowledge of iodine deficiency were assessed by using questionnaires. Household salt iodine concentration was also measured.Results: Total goiter rate was 13.6% and was significantly associated with age [AOR=13.4 (3.2-55.7)]. Eighty two percent of the children had urinary iodine concentration below 50 ìg/L, indicating the presence of moderate iodine deficiency. None of the households were using adequately iodized salt. More than half of the respondents did notknow about the importance of iodized salt. Conclusion: The observed degree of iodine deficiency in children and the limited knowledge about iodine in an urban area such as Hawassa stress the urgent need for implementing interventions to combat iodine deficiency.

Effect of insecticide-treated bed net usage on under-five mortality in northern Ghana

BACKGROUND: Although under-five mortality rate seems to be declining in Ghana, the northern part of the country has higher levels of under-five mortality vis-à-vis the national rates. This research examines the correlates of the high under-five mortality among children in the northern part of Ghana, with emphasis on the usage of insecticide-treated bed net (ITN), as recommended by the World Health Organization. METHODS: A total of 3,839 under-five children sourced from the Ghana Demographic and Health Survey—was used for this study. Univariate descriptive statistics was employed to describe the variables used for the empirical estimation. The maximum likelihood estimation technique was used to estimate a logit model in other to determine the effect of insecticide treated bed net usage on under-five mortality. RESULTS: Insecticide-treated bed net usage among children enhances their survival rates. Thus, under-five mortality among children who sleep under treated bed nets is about 18.8% lower than among children who do not sleep under treated bed nets. While health facility delivery was found to reduce to reduce under-five mortality, child bearing among older women is detrimental to the survival of the child. CONCLUSIONS: The study, therefore, recommends that policies targeting reduction in under-five mortality in northern Ghana should consider not mere availability of ITNs in the household, but advocate the usage of these treated nets. The study recommends to the Ministry of Health to extend their services to unreached rural communities to encourage health facility delivery to reduce under-five mortality
