Salt reduction: need action from govt
High blood pressure is the leading risk for non-communicable diseases in India where the prevalence rates of hypertension are expected to nearly double from 118 million in 2000 to 213 million by 2025. Salt is a leading cause of high blood pressure and has been associated with the risk of vascular disease as well as other serious health problems.
The 2010 Global Burden of Disease study reported excess salt intake to be the seventh leading cause of global mortality responsible for 1.65 million deaths from cardiovascular disease. All member-states of the World Health Organisation (WHO), including India, have adopted a 30% reduction in mean population salt consumption by 2025 as part of the ‘25 by 25’ initiative for the control of non-communicable diseases.
Several studies carried out in the developing countries, like in India, have been reporting an increase in the prevalence of diet related chronic non-communicable diseases (NCDs) like overweight and obesity, diabetes mellitus, hypertension, other cardiovascular diseases (CVDs), cancers etc, especially among urban population.
In support of the development of a national salt reduction strategy for India, the George Institute for Global Health, India has completed a large population survey of dietary salt intake using the 24-hour urine assessment method in urban and rural areas in Delhi/ Haryana and Andhra Pradesh.
Additionally, assessed participant’s knowledge, attitude and behavioural (KAB) practices towards salt consumption and a stakeholder analysis was undertaken involving the government, industry, consumers and civil society organisations as well as a systematic quantitative evaluation of packaged foods available for purchase in Delhi and Hyderabad supermarkets.
There were 1,041 persons selected for the survey in Delhi/Haryana and 712 (68%) agreed to participate. The corresponding number for Andhra Pradesh were 1,291 and 840 (65%). Overall urinary salt excretion was estimated to be 8.59 g/day in Delhi/Haryana and 9.46 g/day in Andhra Pradesh.
Intake was highest in urban slum sites, next highest in rural sites and lowest in slum sites in Delhi/Haryana and the pattern appeared similar in Andhra Pradesh though was not significantly different across area of residence in that state.
In the KAB survey, the majority of participants reported that the maximum salt consumption recommendation as
