To explore dietary salt-related knowledge, attitudes, and behaviors of New Zealand (NZ) adults aged 18-65 years and assess differences by demographic subgroups.
Cross-sectional online survey conducted between June 1, 2018 and August 31, 2018.
Participants were recruited in shopping malls, via social media, and a market research panel.
English-speaking adults residing in NZ.
An amended version of The Pan American and World Health Organization Knowledge, Attitudes, and Behaviors standardized survey tool was used. Demographic data (age, sex, ethnicity, and educational attainment) were also collected.
Descriptive statistics reported. Chi-square test for independence to assess differences by demographics.
The survey was completed by 1,131 adults (mean age 36 ± 15 years; n = 876 [78%] female; n = 661 [78%] NZ European/other; n = 210 [19%] Asian; n =164 [15%] Māori). In addition, 865 participants (83%) knew the primary dietary source of salt; 406 (40%) knew the recommended salt intake; 946 (95%) believed food manufacturers are responsible for sodium reduction; 563 (55%) supported government regulations; and 259 (26%) used food labels. Females and NZ European/other participants reported more favorable salt-reducing behaviors, such as avoiding fast-food and packaged, ready-to-eat foods (P < 0.001).
Improving salt-related knowledge, attitudes, and behaviors in NZ is particularly important for men, underserved populations, and adults aged 45-65 years. A multicomponent, national NZ salt reduction program based on research addressing engagement and effectiveness for at-risk groups is warranted.
探讨18 - 65岁新西兰成年人与膳食盐相关的知识、态度和行为，并评估不同人口亚组之间的差异。
2018年6月1日至2018年8月31日进行的横断面在线调查。
参与者通过购物中心、社交媒体和一个市场研究小组招募。
居住在新西兰的讲英语的成年人。
使用了泛美卫生组织和世界卫生组织知识、态度和行为标准化调查工具的修订版。还收集了人口统计学数据（年龄、性别、种族和教育程度）。
报告描述性统计数据。使用卡方独立性检验评估不同人口统计学特征之间的差异。
1131名成年人完成了调查（平均年龄36±15岁；n = 876 [78%]为女性；n = 661 [78%]为新西兰欧洲人/其他人种；n = 210 [19%]为亚洲人；n = 164 [15%]为毛利人）。此外，865名参与者（83%）知道盐的主要膳食来源；406名（40%）知道推荐的盐摄入量；946名（95%）认为食品制造商有责任减少钠含量；563名（55%）支持政府监管；259名（26%）会查看食品标签。女性和新西兰欧洲人/其他参与者报告了更积极的减盐行为，如避免食用快餐和包装即食食品（P < 0.001）。
提高新西兰人对盐相关的知识、态度和行为，对男性、服务不足人群以及45 - 65岁的成年人尤为重要。有必要基于针对高危人群参与度和有效性的研究，开展一项多组分的新西兰全国减盐计划。
