Hey Joel, great report- overall, I am also pretty excited about interventions for hypertension. A couple of questions about your report:
You decided to narrow down on sodium policy taxation advocacy- whilst I think this is probably one of the more appealing interventions in this space, I wonder whether you considered other interventions e.g. community salt substitution, which was looked into by Givewell and recently had a very large RCT conducted.
The impact of sodium reduction extends beyond BP effects- Although the majority of the health effect of sodium reduction does seem to be through reducing BP, there are some other causal mechanisms that are suggested e.g. reducing oxidative stress, reducing sympathetic tone. I wonder whether you looked into/considered these
The cost of advocacy- it seems like you have by and large taken the cost of quite a lean charity doing this. I wonder whether it would be worthwhile looking at organisations that have previously successfully helped advocate for taxation policy, and estimated their size/cost. I would imagine this might be a higher cost by several factors
Are there good advocacy groups out there- I would be really interested to know whether there are highly effective organisations advocacy for sodium taxation policy already out there, that funders might be able to look int further + potentially fund!
A great report- thanks Joel!
Thank you- edited!
