消费者知识被认为在管理与心血管疾病相关的风险因素方面发挥作用，并可能受到教育水平的影响。总体上探讨了人口知识，行为和实际盐消费量之间的关系，并与教育程度较低的个人进行了比较。一项横断面调查是在一个年龄和性别分层随机抽样的1395名参与者从城市和农村地区的印度北部和南部。一个单一的24小时尿液样本，参与者的身体测量和问卷调查数据收集。参与者的平均年龄为40岁，47%为女性，平均24小时尿盐排泄量为9.27（8.87-9.69）g/天。许多参与者报告了有利的知识和行为，以尽量减少与盐有关的风险。这些行为中的一些与减少盐摄入量有关烹饪时少用盐，避免零食，namkeens和避免泡菜（所有p < 0.003）。平均盐摄入量在受教育程度较高（9.21，8.55-9.87 g/天）与受教育程度较低（9.34，8.57-10.12 g/天）的个体中相当（p = 0.82）。受教育程度较高的群体与受教育程度较低的群体之间的知识和行为模式没有实质性差异，也没有明确的证据表明教育水平影响盐的摄入量。一些消费者在食物制备和食用含盐产品过程中使用盐的行为与实际盐的消费量有关，因此似乎提供了一个干预的机会。这将是一个合理的重点，为政府主导的教育运动，针对盐。
Consumer knowledge is understood to play a role in managing risk factors associated with cardiovascular disease and may be influenced by level of education. The association between population knowledge, behaviours and actual salt consumption was explored overall, and for more-educated compared to less-educated individuals. A cross-sectional survey was done in an age-and sex-stratified random sample of 1395 participants from urban and rural areas of North and South India. A single 24-h urine sample, participants' physical measurements and questionnaire data were collected. The mean age of participants was 40 years, 47% were women and mean 24-h urinary salt excretion was 9.27 (8.87-9.69) g/day. Many participants reported favourable knowledge and behaviours to minimise risks related to salt. Several of these behaviours were associated with reduced salt intake-less use of salt while cooking, avoidance of snacks, namkeens, and avoidance of pickles (all p < 0.003). Mean salt intake was comparable in more-educated (9.21, 8.55-9.87 g/day) versus less-educated (9.34, 8.57-10.12 g/day) individuals (p = 0.82). There was no substantively different pattern of knowledge and behaviours between more-versus less-educated groups and no clear evidence that level of education influenced salt intake. Several consumer behaviours related to use of salt during food preparation and consumption of salty products were related to actual salt consumption and therefore appear to offer an opportunity for intervention. These would be a reasonable focus for a government-led education campaign targeting salt.
