Impact of a hospital-based educational intervention on dietary salt-related knowledge and behaviour in a cardiac care unit population in Lebanon

Abstract

Cardiovascular disease is the most common cause of morbidity and mortality worldwide. Numerous strategies have been effective in reducing cardiovascular disease risk, from pharmacological approaches to lifestyle modification interventions. One of these strategies includes the reduction in dietary sodium which in turn reduces cardiovascular risk by reducing high blood pressure, perhaps the most important cardiovascular risk factor. We evaluated an educational dietary salt reduction intervention in a cardiac care unit population in Lebanon, assessing salt related knowledge and behaviours before and after administering an evidence-based educational leaflet to patients. Salt-related knowledge improved significantly immediately post-intervention and subsequently fell on 4-week follow-up, but remained above baseline. Three of the four salt-related behaviours measured improved on 4-week follow-up: trying to buy low-salt foods increased from 54% to 74% (P=0.007), adding salt at the table reduced from 44% to 34% (P=0.03) and trying to buy food with no added salt increased from 24% to 52% (P=0.02) of the cohort. Adding salt during cooking did not differ significantly. A trend towards improved behavioural risk category in the cohort overa...Continue Reading

Cardiovascular Risk Prediction

Cardiovascular risk prediction models based on classical risk factors identified in epidemiological studies are useful in primary prevention of cardiovascular disease in individuals. Here is the latest research.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
