Sweetened beverage consumption and risk of coronary heart disease in women.

Overview

Fung TT et al.. Am J Clin Nutr 2009 · PMID 19211821 · DOI 10.3945/ajcn.2008.27140

Two or more sugary drinks a day: 35% higher heart disease risk; diet drinks not linked.

Does the study support the specific claim? Yes · Methodological quality: high

Original publication

Plain-language summary

Study explained simply
What did the researchers want to find out?

Is SSB consumption associated with CHD in women?

How was the study done?

Prospective cohort (NHS) 1980-2004.

How many people, animals or samples were studied?

88,520; 3,105 CHD cases; Women aged 34-59 without CHD, stroke, diabetes

What was actually found?

RRs 1.0, 0.96, 1.04, 1.23 (1.06-1.43) for 1/d and 1.35 (1.07-1.69) for >=2/d (P trend <0.001); attenuated but significant after BMI, energy and diabetes adjustment; ASB not associated.

How large was the observed effect?

RR 1.35 (1.07-1.69)

What do the results mean in everyday life?

Sugary drinks linked to heart disease.

What are the study's limitations?

Observational design; residual confounding possible; Self-reported dietary intake

What does it say about Elawady's specific claim?

Supports C-SOD-03; contradicts C-SOD-10.

Do the results apply to Germany and Europe?

High.

What can explicitly not be concluded from this study?

Causation.

What the archive says about the study

(Narrative) 24-year follow-up of 88,000 nurses: two or more servings per day raised CHD risk by 35%.

A. What was actually studied?

SSB and CHD in women.

B. What did the authors find?

RR 1.35 for >=2/d; ASB not associated.

C. What conclusions do the authors themselves draw?

As above.

D. What does the archive derive from it?

Causal 'raised'.
