I'll again quote from Labonté and Ruckert, who had stats in their study—I don't have them in my notes—basically showing that most analyses of the TPP show that it will only improve the GDP by a tiny, tiny percentage in most countries. I think there was one exception, and that might have been Vietnam. It wasn't even going to be very good for trade. Their conclusion, which I do have in front of me, states: “More importantly, there is no evidence that the TPP will substantively benefit most workers in most TPP countries.”
You're right in that economics is usually considered to be one of the primary determinants of health, so if the economic benefits were large, they could potentially increase health and maybe lifespan, but the analyses in the academic literature do not show that the TPP will be substantially beneficial, even from a trade or economic perspective.
