Abstract
The study aimed to assess public awareness of the correlation between arterial hypertension and excessive salt consumption, as well as to analyze knowledge, attitudes, and practices related to salt intake. A cross-sectional study was conducted involving 120 respondents. To evaluate the correlation, odds ratios (OR) and 95% confidence intervals (95% CI) were calculated.
Half of the respondents were unaware of the recommended daily salt intake; however, the majority recognized its harmful effects on health. A higher level of education was significantly associated with better awareness (OR=3.1), while frequent salt consumers had higher odds of developing hypertension (OR=2.2). Despite generally positive attitudes, excessive salt consumption remains prevalent in practice. International experience and recommendations from the World Health Organization confirm that reducing salt intake is one of the most effective non-pharmacological strategies for the prevention of hypertension. The study highlights the need for comprehensive public health interventions.
