Potato Consumption and Risk of Mortality

2019-01-30 16:40:37 | BioPortfolio


Although previous studies have linked fried potato consumption with the incidence of mortality in the US population, the association between potato consumption and mortality in the Chinese population remains unknown.


This study investigated the association of potato, fried potato, unfried potato, and sweet potato consumption with the incidence of mortality in the China Health and Nutrition Survey (CHNS).We analyzed the CHNS data and the participants (n = 14,116) over 20 years old were followed for up to 22 years. The participants were initially free of cancer, myocardial infarction, apoplexy, and pregnancy. Potato consumption was assessed using validated semi-quantitative food questionnaires (FFQ) in interviews. In each wave of interviews, the participants' situations such as alive, dead, or dying was listed and the death months were recorded. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were estimated using Cox proportional hazard models with adjustment of potential confounders.In the CHNS cohort, total potato, fried potato, unfried potato, and sweet potato consumption were all strongly associated with a reduction in all-cause mortality in both Chinese women and men.
