Com Dr. Eduardo Costa fizemos um estudo semelhante baseado na Pesquisa sobre PA no RS de 1978, publicado em 1994 (Eduardo de  A  Costa, Geoffrey Rose, Carlos H. Klein and Aloyzio C.

Reducing sodium in U.S. may save hundreds of thousands of lives over 10 years

February 11, 2013 

Study Highlights:

• Reducing sodium consumption could save 280,000 to 500,000 lives in the United States over 10 years.
• Researchers used three computer simulations to determine ways to reduce sodium to save lives.
• Americans consume about 3,600 mg of sodium per day — more than twice the recommended limit.

DALLAS, Feb. 11, 2013 — Less sodium in the U.S. diet could save 280,000 to 500,000 lives over 10 years, according to new research in the American Heart Association journalHypertension.

Using computer simulations and models researchers projected the effects of small (about 5 percent of a teaspoon of salt per person per day), steady annual reductions of sodium consumption in the U.S. diet, reducing sodium consumption by 40 percent to about 2,200 mg/day over 10 years.

Key findings include:

• A gradual reduction in sodium consumption by 40 percent to about 2,200 mg/day over 10 years is projected to save hundreds of thousands of lives – between 280,000 and 500,000 depending on the modeled assumptions.
• About 60 percent more deaths could be averted over this time period if these same reductions could be achieved more quickly (500,000 to 850,000 lives).

Three research groups contributed to the study, each using a different approach for their simulation. One approach used observational cardiovascular outcome follow-up data, while the other two based their projections on established evidence that salt reduction lowers blood pressure. These two groups inferred the cardiovascular effects of reducing sodium from data about the relationship of blood pressure to cardiovascular disease./.../
