背景:这项研究的目的是估计与孟加拉国家庭碘盐充足性有关的个人和社区水平的因素。
方法:在本研究中,我们使用了2019年多指标类集调查数据。从孟加拉国总共选择了61.242个家庭作为样本。在我们对社会经济差异的研究中,我们应用了浓度指数法。为了在个人和社区层面确定与盐中碘充足相关的因素,我们采用多水平逻辑回归。除了研究中使用的多层次回归,我们还应用了空间分析。
结果:结果表明,家庭食盐中碘充足的患病率为57.8%(95%置信区间为57.4至58.2)。农村地区的碘浓度高于城市地区。根据多层次模型,年轻女性(调整后的赔率比[AOR]0.70),穆斯林妇女(aOR0.89),与同龄人相比,文盲妇女(aOR0.80)和贫困家庭(aOR0.33)不太可能在浓缩盐中消耗碘。与参照组相比,残疾妇女和媒体接触少的妇女在盐中碘充足的可能性较低。此外,与农村地区的家庭相比,城市地区的家庭在盐中碘充足的可能性更高。Barisal,聊天图,达卡,Khulna,Mymensingh,与Sylhet部门相比,Rajshahi和Rangpur部门的盐碘含量较低。
结论:研究结果表明,宗教,身体残疾和接触媒体对碘盐摄入量的存在具有同等影响。此外,女人的年龄,财富地位,受教育程度和户主的教育背景对家庭食盐中碘的充足性具有积极作用。鉴于这些结果,建议决策者优先考虑旨在提高碘浓度的努力,特别关注大众媒体广告,特别是在农村地区(不包括Sylhet部门)。
BACKGROUND: The aim of this study is to estimate the factors at both the individual and community levels related to the
adequacy of iodized salt in households in Bangladesh.
METHODS: For this study we utilized the 2019 Multiple Indicator Cluster Survey data. A total of 61 242 households were chosen as samples from Bangladesh. In our study of socio-economic disparities, we applied a concentration indexing method. To identify the factors associated with the
adequacy of iodine in salt at both the individual and community levels, we employed multilevel logistic regression. Aside from the multilevel regression used in the study, we also applied spatial analysis.
RESULTS: The results indicated that the prevalence of iodine
adequacy in household salt was found to be 57.8% (95% confidence interval 57.4 to 58.2). Rural areas have a higher concentration of iodine than urban areas. According to the multilevel model, younger women (adjusted odds ratio [aOR] 0.70), Muslim women (aOR 0.89), illiterate women (aOR 0.80) and those from poor households (aOR 0.33) were found to be less likely to consume iodine in concentrated salt compared with their counterparts. Disabled women and those with low media exposure have a lower likelihood of iodine adequacy in salt compared to their reference group. Furthermore, households in urban areas exhibited higher odds of having iodine
adequacy in salt compared with households in rural areas. Barisal, Chattogram, Dhaka, Khulna, Mymensingh, Rajshahi and Rangpur Divisions have lower iodine
adequacy in salt compared with Sylhet Division.
CONCLUSIONS: The findings reveal that religion, physical disability and exposure to media exert an equal influence on the presence of iodized salt intake. Moreover, women\'s age, wealth status, education level and the educational background of the household head positively contribute to the adequacy of iodine in household salt. In light of these results, policymakers are advised to prioritize efforts aimed at enhancing iodine concentration, with a particular focus on mass media advertising, especially in rural areas (excluding Sylhet Division).
