The scientific evidence base in support of salt reduction is strong but the data required to translate these insights into reduced population salt intake are mostly absent. The aim of this research project is to develop the evidence base required to formulate and implement a national salt reduction programme for India.
The research will comprise three components: a stakeholder analysis involving government, industry, consumers and civil society organisations; a population survey using an age-stratified and sex-stratified random samples drawn from urban (slum and non-slum) and rural areas of North and South India; and a systematic quantitative evaluation of the nutritional components of processed and restaurant foods. The stakeholder interviews will be analysed using qualitative methods to summarise the main themes and define the broad range of factors influencing the food environment in India. The population survey will estimate the mean daily salt consumption through the collection of 24 h urine samples with concurrent dietary surveys identifying the main sources of dietary sodium/salt. The survey of foods will record the nutritional composition of the chief elements of food supply. The findings from this research will be synthesised and proposals for a national salt reduction strategy for India will be developed in collaboration with key stakeholders.
This study has been approved by the Human Research Ethics Committees of the University of Sydney and the Centre for Chronic Disease Control in New Delhi, and also by the Indian Health Ministry's Screening Committee. The project began fieldwork in February 2014 and will report the main results in 2016. The findings will be targeted primarily at public health policymakers and advocates, but will be disseminated widely through other mechanisms including conference presentations and peer-reviewed publications, as well as to the participating communities.
支持减少盐摄入的科学证据基础坚实，但将这些见解转化为降低人群盐摄入量所需的数据大多缺失。本研究项目的目的是建立制定和实施印度全国性减盐计划所需的证据基础。
该研究将包括三个部分：涉及政府、行业、消费者和民间社会组织的利益相关者分析；从印度北部和南部城市（贫民窟和非贫民窟）及农村地区抽取的按年龄和性别分层的随机样本进行的人口调查；以及对加工食品和餐馆食品营养成分的系统定量评估。将采用定性方法分析利益相关者访谈，以总结主要主题并确定影响印度食品环境的广泛因素。人口调查将通过收集24小时尿液样本并同时进行饮食调查来估计每日平均盐摄入量，饮食调查将确定膳食钠/盐的主要来源。食品调查将记录食品供应主要成分的营养成分。本研究的结果将进行综合，并与主要利益相关者合作制定印度全国减盐战略的建议。
本研究已获得悉尼大学和新德里慢性病控制中心的人类研究伦理委员会以及印度卫生部筛查委员会的批准。该项目于2014年2月开始实地调查，并将于2016年报告主要结果。研究结果将主要面向公共卫生政策制定者和倡导者，但也将通过其他机制广泛传播，包括会议报告、同行评审出版物以及参与社区。
