Resumen

MARTINEZ-GONZALEZ, Miguel Ángel  y  VAZQUEZ-RUIZ, Zenaida. Pro-vegetarian dietary pattern and all-cause mortality. Rev. chil. nutr. [online]. 2014, vol.41, n.4, pp.367-371. ISSN 0717-7518.  http://dx.doi.org/10.4067/S0717-75182014000400004.

Vegetarian diets have been associated with a reduced mortality. Since a pure vegetarian diet might not be easily embraced by many individuals, consuming preferentially plant-based foods would be a more easily understood message. A pro-vegetarian food pattern (FP) emphasizing preference for plant-based foods might reduce all-cause mortality. In the PREDIMED cohort we followed 7,216 participants (57% women, mean age 67 years old) at high cardiovascular risk for a median of 4.8 years. Diet was assessed yearly through a validated 137-item semi-quantitative food-frequency questionnaire. Fruit, vegetables, nuts, cereals, legumes, olive oil and potatoes consumption were positively considered while animal fats, eggs, fish, dairy products and meat or meat products consumption were negatively considered. Energy-adjusted quintiles were used to assign points to build the Pro-vegetarian FP (range: 12 to 60 points). There were 323 deaths during follow-up (76 from cardiovascular disease, 130 from cancer, 117 for non-cancer, non-cardiovascular causes) and were confirmed by reviewing medical records and verification in the National Death Index. We observed that among omnivorous subjects at high cardiovascular risk, better conformity with a FP that emphasized plant-derived foods was associated with a reduced risk of all-cause mortality.

Palabras clave : pro-vegetarian food pattern; Predimed study mortality.
