The Australian population consumes more salt than recommended and this increases the risk of raised blood pressure and cardiovascular disease. In 2015, a state-wide initiative was launched in the Australian state of Victoria to reduce population salt intake. This study examines whether salt-related knowledge, attitudes and behaviors (KABs) of Victorian adults changed following the first 22 months of a consumer awareness campaign targeting parents. Repeated cross-sectional surveys of adults (18-65 years) recruited from research panels. Analyses were weighted to reflect the Victorian population. In both surveys mean age of participants (1584 in 2015 and 2141 in 2018) was 41 years, and 51% were female. This includes 554 parents/caregivers in 2015 and 799 in 2018. Most indicators of KAB remained unchanged. Among parents/caregivers the percentage who agreed limiting salt in their child's diet was important increased by 8% ( = 0.001), and there was a 10% reduction in the percentage who reported placing a saltshaker on the table and a 9% reduction in those who reported their child added salt at the table (both < 0.001). Some small adverse effects on other indicators were also observed. During the first 22 months of a salt reduction consumer awareness campaign, there were limited changes in KAB overall, however the target audience reported positive changes regarding their children, which aligned with the campaign messages.
澳大利亚人口的盐摄入量超过了推荐水平，这增加了患高血压和心血管疾病的风险。2015年，澳大利亚维多利亚州发起了一项全州范围的倡议，以减少居民的盐摄入量。本研究调查了针对家长的消费者意识运动开展22个月后，维多利亚州成年人与盐相关的知识、态度和行为（KABs）是否发生了变化。对从研究小组招募的成年人（18 - 65岁）进行重复横断面调查。分析结果经过加权以反映维多利亚州的人口情况。在两次调查中，参与者的平均年龄（2015年为1584人，2018年为2141人）均为41岁，其中51%为女性。这包括2015年的554名家长/照顾者和2018年的799名。大多数KAB指标保持不变。在家长/照顾者中，同意限制孩子饮食中盐摄入量很重要的比例增加了8%（P = 0.001），报告在餐桌上放置盐瓶的比例下降了10%，报告孩子在餐桌上加盐的比例下降了9%（两者P均<0.001）。还观察到对其他指标有一些小的不利影响。在减少盐摄入量的消费者意识运动的前22个月里，KAB总体变化有限，然而目标受众报告了在孩子方面的积极变化，这与运动信息一致。
