The Nutritrack Database: An annually updated database of information on packaged foods and beverages sold at major supermarkets in New Zealand (2013 to 2023)

Overview: Nutritrack is a database of annually updated information on packaged foods and beverages sold at major supermarkets in New Zealand.Data collection methods: Annual, systematic surveys were undertaken by trained fieldworkers in four supermarket stores in the Auckland region at the same time each year, enabling tracking of labelling, ingredients, and nutrient composition of New Zealand packaged food and beverage products over time, for the years 2013 to 2023 (inclusive).Data quality: Quality checks were undertaken on a random 15% sample of products where data entered in all product fields were compared with source photographs for accuracy. Reports were also run across all products to identify outlier values, ensure complete and correct nutrient data, and maximise consistency of the categorisation of products over time. Data accuracy across critical fields was monitored during and after data collection each year to maximise the accuracy of data collection and entry, and are available in the summary attachment.Data ownership and access: The Nutritrack database is owned and managed by The University of Auckland. The methods may be published if cited appropriately. Access to the data for external research collaborators has now closed. Access to the data for internal collaborators may be available - please contact the principal investigator with inquiries.Further information: Further information on data collection methods and database features is available as an attachment. A sample of the data is also available as an attachment.

{'Overview': '概览：Nutritrack数据库收录了新西兰各大超市每年更新的包装食品和饮料信息。数据收集方法：通过训练有素的实地工作人员每年在同一时间对奥克兰地区的四家超市进行系统性调查，从而追踪新西兰包装食品和饮料产品在2013年至2023年（含）期间的标签、成分和营养成分的变化。数据质量：对随机选取的15%产品样本进行了质量检查，以确保所有产品字段输入的数据与源照片相匹配，以验证其准确性。同时，对所有产品进行了报告分析，以识别异常值，确保营养数据的完整性和准确性，并最大化产品分类的一致性。每年在数据收集期间及之后均对关键字段的数据准确性进行监控，以确保数据收集和录入的最大准确性，相关总结附件可供查阅。数据所有权与访问：Nutritrack数据库由奥克兰大学拥有和管理。若引用得当，调查方法可予以发表。外部研究合作者的数据访问现已关闭。内部合作者的数据访问可能可行，如有查询，请联系主要研究员。更多信息：有关数据收集方法和数据库特征的详细信息可在附件中找到。数据样本也作为附件提供。', 'Data collection methods': '数据收集方法：通过训练有素的实地工作人员每年在同一时间对奥克兰地区的四家超市进行系统性调查，从而追踪新西兰包装食品和饮料产品在2013年至2023年（含）期间的标签、成分和营养成分的变化。', 'Data quality': '数据质量：对随机选取的15%产品样本进行了质量检查，以确保所有产品字段输入的数据与源照片相匹配，以验证其准确性。同时，对所有产品进行了报告分析，以识别异常值，确保营养数据的完整性和准确性，并最大化产品分类的一致性。每年在数据收集期间及之后均对关键字段的数据准确性进行监控，以确保数据收集和录入的最大准确性，相关总结附件可供查阅。', 'Data ownership and access': '数据所有权与访问：Nutritrack数据库由奥克兰大学拥有和管理。若引用得当，调查方法可予以发表。外部研究合作者的数据访问现已关闭。内部合作者的数据访问可能可行，如有查询，请联系主要研究员。', 'Further information': '更多信息：有关数据收集方法和数据库特征的详细信息可在附件中找到。数据样本也作为附件提供。'}
