Abstract

OBJECTIVE: To evaluate the association of changes in red meat consumption with total and cause specific mortality in women and men. DESIGN: Two prospective cohort studies with repeated measures of diet and lifestyle factors. SETTING: Nurses' Health Study and the Health Professionals Follow-up Study, United States. PARTICIPANTS: 53 553 women and 27 916 men without cardiovascular disease or cancer at baseline. MAIN OUTCOME MEASURE: Death confirmed by state vital statistics records, the national death index, or reported by families and the postal system. RESULTS: 14 019 deaths occurred during 1.2 million person years of follow-up. Increases in red meat consumption over eight years were associated with a higher mortality risk in the subsequent eight years among women and men (both P for trend<0.05, P for heterogeneity=0.97). An increase in total red meat consumption of at least half a serving per day was associated with a 10% higher mortality risk (pooled hazard ratio 1.10, 95% confidence interval 1.04 to 1.17). For processed and unprocessed red meat consumption, an increase of at least half a serving per day was associated with a 13% higher mortality risk (1.13, 1.04 to 1.23) and a 9% higher mortality risk (1.09, 1.02 to 1.17), respectively. A decrease in consumption of processed or unprocessed red meat of at least half a serving per day was not associated with mortality risk. The association between increased red meat consumption and mortality risk was consistent across subgroups defined by age, physical activity, dietary quality, smoking status, or alcohol consumption. CONCLUSION: Increases in red meat consumption, especially processed meat, were associated with higher overall mortality rates.

  • Substantial evidence from randomized trials and observational studies suggests that high consumption of red meat, especially processed red meat, is associated with an increased risk of mortality and major chronic diseases, including coronary heart disease.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
