From 2015 to 2020 a state-wide salt-reduction initiative was launched in Victoria, Australia, including an awareness campaign focused on parents with children <18 years of age. To evaluate the impact of the campaign on salt-related knowledge, attitudes and behaviors (KABs) we have assessed trends in salt-related KAB pre- and post-delivery of the campaign in parents, as well as within the wider adult population. Cross-sectional surveys of adults aged 18-65 years were undertaken pre- (2015: = 821 parents; = 1527 general sample) and post-campaign (2019: = 935 parents; = 1747 general sample). KABs were assessed via an online survey. Data were analyzed with regression models and adjusted for covariates. Among parents, around one-quarter of salt-related KABs shifted in a positive direction, but changes were small: there was a 6% (95% CI 2, 11%) increase in the percentage who knew the main source of salt in the diet and reductions in the percentage who reported placing a salt shaker on the table (-8% (95%CI -12, -3)) and that their child added salt at the table (-5% (95% -9, -0.2)). Among the wider adult sample, even fewer shifts in KAB were observed, with some behaviors worsening at follow-up. These findings indicate that this consumer awareness campaign had minimum impact.
从 2015 年到 2020 年，澳大利亚维多利亚州发起了一项全范围的减盐倡议，其中包括一项针对 18 岁以下儿童父母的宣传活动。为了评估该活动对盐相关知识、态度和行为（KAB）的影响，我们评估了在宣传活动前后父母以及更广泛的成年人群体中盐相关 KAB 的趋势。对 18-65 岁成年人进行了横断面调查，在活动前（2015 年：=821 名父母；=1527 名一般样本）和活动后（2019 年：=935 名父母；=1747 名一般样本）进行了在线调查。通过在线调查评估 KAB。使用回归模型分析数据，并对协变量进行调整。在父母中，大约四分之一的盐相关 KAB 朝着积极的方向转变，但变化很小：有 6%（95%CI 2, 11%）的人知道饮食中盐的主要来源，而报告在餐桌上放盐瓶的人的比例减少了（-8%（95%CI -12, -3）），他们的孩子在餐桌上加盐的比例减少了（-5%（95% -9, -0.2））。在更广泛的成年样本中，观察到的 KAB 变化更少，有些行为在随访时恶化。这些发现表明，这场消费者意识宣传活动的影响很小。
