Assessment of Nigerias National Sodium Reduction Program Using WHOs SHAKE Strategy Evaluating Implementation and Scale-Up Across Three States in Adults Aged 18 to 69

What this Trial Is About

Researchers are evaluating the implementation and scale-up of Nigerias national sodium reduction program led by the Nigerian Agency for Food and Drug Administration and Control NAFDAC. This program uses the WHOs SHAKE package, which includes strategies like surveillance of salt intake, industry engagement, labeling standards, consumer education, and promoting healthy eating environments to reduce sodium intake and prevent hypertension. The study uses a type III hybrid, mixed methods design to assess the programs progress and effectiveness in real-world settings. The study involves enrolling adult household representatives from three Nigerian states to participate in repeated waves of data collection. Participants take part in surveys such as the STEPs survey, provide 24-hour and spot urine samples, blood samples for fatty acid estimation, and complete multiple 24-hour dietary recalls. These assessments occur at baseline Wave 1, and follow-ups at around 18 months Wave 2 and 36 months Wave 3 to monitor dietary sodium sources, population sodium intake, and program implementation outcomes. Participants will be involved in interviews, surveys, and biological sample collections over the study period. Researchers will use various frameworks and methods to evaluate program reach, adoption, feasibility, fidelity, acceptability, and cost. Key outcomes include changes in mean population sodium intake and 24-hour urinary sodium from baseline through follow-up waves, along with shifts in dietary sources of sodium and knowledge, attitudes, and behaviors about sodium intake. The total participation period spans approximately three years, with repeated assessments to track progress and impact.
