Abstract

Purpose High salt intake is one of the most important causes of some serious health problems. This study aims to evaluate the effects of a salt intake reduction intervention based on social marketing model in Ahwaz city, Iran. Design/methodology/approach This was a before-after study with a control group using social marketing approach. Two similar residential complexes were chosen and randomly assigned into intervention or control groups. One hundred and thirty women were selected in each complex. Formative research was conducted, including focus group discussions (FGDs), a survey to identify cognitive factors of salt intake and a 24-h urine test to estimate salt intake value. Based on the results of the formative research, an intervention was planned and implemented for one month in the intervention group. The postintervention assessment was conducted repeating the cognitive survey and urine test. Statistical tests, including independent T-Test and paired T-Test, were used to compare the experimental and control groups. Findings Before the intervention mean salt intake levels were 8,574.41 and 8,282.23 mg/day in the intervention and control groups, respectively. The total mean scores of cognitive and behavioral factors were 25.32 and 26.41 out of 59 in the intervention and control groups, respectively. After the intervention in the intervention group, daily salt intake decreased significantly by 1,558.83 mg/day and mean total scores of cognitive and behavioral factors increased significantly by 10.73. Research limitations/implications Due to sodium excretion fluctuations in different days and/or different people, estimating sodium excretion based on one-day sample may have bias. Still, 24-h urine test is the most effective method to estimate population mean salt intake which is used in this study. Practical implications The authors could not investigate urine sodium levels in other family members due to resource limitations. Knowing this could help us to see if similar results are achieved. Originality/value Despite the lack of public policies to decrease population salt intake, interventions based on social marketing can significantly reduce salt intake. However, the long-term effect of such interventions will require further investigation.
在缺乏适当的国家政策和法规的情况下,是否仍有可能减少人口的盐摄入量?社会营销干预
目的高盐摄入是导致一些严重健康问题的最重要原因之一。本研究旨在评估基于社会营销模型的减少盐摄入量干预在伊朗阿瓦兹市的效果。设计/方法/方法这是一项使用社会营销方法对对照组进行的前后研究。选择两个类似的住宅小区,并随机分为干预组或对照组。在每个综合体中选出130名妇女。进行了形成性研究,包括焦点小组讨论(FGDs)、确定盐摄入量认知因素的调查以及评估盐摄入量的24小时尿检。根据形成性研究的结果,在干预组中计划并实施为期一个月的干预。干预后评估重复认知调查和尿检。统计学检验,包括独立T检验和配对T检验,用于比较实验组和对照组。结果干预前平均盐摄入量分别为8574.41和8282.23 干预组和对照组分别为mg/天。干预组和对照组的认知和行为因素总分分别为25.32分和26.41分(满分59分)。干预组干预后,每日盐摄入量显著减少1558.83 mg/天,认知和行为因素的平均总分显著增加10.73。研究局限性/含义由于不同日期和/或不同人群的钠排泄量波动,基于一天样本估计钠排泄量可能存在偏差。尽管如此,24小时尿检是本研究中估计人群平均盐摄入量的最有效方法。实际意义由于资源限制,作者无法调查其他家庭成员的尿钠水平。了解这一点可以帮助我们看看是否能取得类似的结果。独创性/价值尽管缺乏减少人口盐摄入量的公共政策,但基于社会营销的干预措施可以显著减少盐摄入量。然而,这种干预措施的长期效果需要进一步调查。
