Abstrakt:	Objectives: This study aimed to examine the distribution of daily salt intake across the hypertension care cascade and assess the proportional distribution of these care cascade categories across various salt consumption level. Design: A population-based national cross-sectional study. Settings: Data from the Bangladesh STEPS 2018 survey were used, encompassing both urban and rural strata within all eight divisions. National estimates were generated from weighted data. Participants: A diverse population of 6754 men and women aged 18-69 years was included in the study. Outcome Measures: Daily salt consumption was estimated using the spot urine sodium concentration following Tanaka equation. Distribution of salt intake among different categories of hypertension care cascade, including hypertensives, aware of hypertension status, on treatment and under control, was assessed. Results: Individuals with hypertension consume more salt on average (9.18 g/day, 95% CI 9.02 to 9.33) than those without hypertension (8.95 g/day, 95% CI 8.84 to 9.05) (p<0.02). No significant differences were found in salt intake when comparing aware versus unaware, treated versus untreated and controlled versus uncontrolled hypertension. In the overall population, 2.7% (95% CI 2.1% to 3.6%) of individuals without hypertension adhered to the recommended salt intake (<5 g/day) while 1.6% (95% CI 1.0% to 2.4%) with hypertension did so (p<0.03). Among individuals with hypertension, 2.4% (95% CI 1.4% to 4.0%) of those aware followed the guideline while only 0.8% (95% CI 0.4% to 1.9%) of those unaware adhered (p<0.03). Additionally, no significant differences were observed in adherence between the treated versus untreated and controlled versus uncontrolled hypertension. Conclusions: Individuals with hypertension consume significantly more salt than those without, with no significant variations in salt intake based on aware, treated and controlled hypertension. Adhering to WHO salt intake guidelines aids better blood pressure management. By addressing salt consumption across hypertension care cascade, substantial progress can be made in better blood pressure control. Competing Interests: Competing interests: None declared.
