Smil: America’s Wa(i)sting Problem

Vaclav Smil:

Even after throwing away some 40 percent of its abundant food supply, the United States still has the industrialized world’s most overweight population. America similarly produces more energy per capita than any other major rich economy — so much so that if the United States were to consume that energy at a rate comparable to Germany or France, it would be a massive energy exporter. Instead, America imports more than 25 percent of its energy, paying more than $2 trillion for the privilege over the past decade — and still ends up with little to show for it. The United States now faces the choice of curbing its energy appetite with deliberation, commitment, and foresight, or waiting for the unraveling economy to put it on a painful crash diet.

Baseline prehypertension and risk of stroke

New paper:

Presence of baseline prehypertension and risk of incident stroke: A meta-analysis


Objective: To qualitatively and quantitatively assess the association of prehypertension with incident stroke through a meta-analysis of prospective cohort studies.

Methods: We searched Medline, Embase, the Cochrane Library, and bibliographies of retrieved articles. Prospective cohort studies were included if they reported multivariate-adjusted relative risks RRs and corresponding 95%confidence intervals CI of stroke with respect to baseline prehypertension.

Results: Twelve studies with 518,520 participants were included. Prehypertension was associated with risk of stroke RR 1.55, 95% CI 1.35–1.79; p < 0.001. Seven studies further distinguished a low prehypertensive population systolic blood pressure [SBP] 120–129 mm Hg or diastolic blood pressure [DBP] 80–84 mm Hg and a high prehypertensive population SBP 130–139 mm Hg or DBP 85–89 mm Hg. Among persons with lower-range prehypertension, stroke risk was not significantly increased RR 1.22, 0.95–1.57. However, for persons with higher values within the prehypertensive range, stroke risk was substantially increased RR 1.79, 95% CI 1.49–2.16.

Conclusions: Prehypertension is associated with a higher risk of incident stroke. This risk is largely driven by higher values within the prehypertensive range and is especially relevant in nonelderly persons. Randomized trials to evaluate the efficacy of blood pressure reduction in persons with this designation are warranted.
