Ultra-processed food consumption is associated with renal function decline in older adults: a prospective cohort study

Ultra-processed food (UPF) consumption has been associated with increased risk of cardiovascular risk factors and mortality. However, little is known on the UPF effect on renal function. The aim of this study is to assess prospectively the association between consumption of UPF and renal function decline. This is a prospective cohort study of 1312 community-dwelling individuals aged 60 and older recruited during 2008–2010 and followed up to December 2015. At baseline, a validated dietary history was obtained. UPF was identified according to NOVA classification. At baseline and at follow-up, serum creatinine (SCr) and estimated glomerular filtration rate (eGFR) levels were ascertained and changes were calculated. A combined end-point of renal decline was considered: SCr increase or eGFR decreased beyond that expected for age. Logistic regression with adjustment for potential confounders was performed. During follow-up, 183 cases of renal function decline occurred. The fully adjusted odds ratios (95% CI) of renal function decline across terciles of percentage of total energy intake from UPF were 1.56 (1.02–2.38) for the second tercile, and 1.74 (1.14–2.66) for the highest tercile; p-trend was 0.026. High UPF consumption is independently associated with an increase higher than 50% in the risk of renal function decline in Spanish older adults.

Abstract Objectives Ultra-processed food intake has been associated with chronic conditions. The aim of this study was to assess the relationship between ultra-processed food intake and incident frailty in community-dwelling older adults. Methods Prospective cohort study with 1822 individuals aged ≥60 who were recruited during 2008–2010 in Spain. At baseline, food consumption was obtained using a validated computerized face-to-face dietary history. Ultra-processed foods were identified according to the nature and extent of their industrial processing (NOVA classification). In 2012, incident frailty was ascertained based on Fried's criteria. Statistical analyses were performed with logistic regression and adjusted for the main potential confounders. Results After a mean follow-up of 3.5 years, 132 cases of frailty were identified. The odds ratios (95% confidence interval) for frailty across increasing quartiles of the percentage of total energy intake from ultra-processed foods were: 1.00, 1.52 (0.78–2.96), 2.98 (1.62–5.50), and 3.67 (2.00–6.73); p for linear trend: <0.001. Results were similar when food consumption was expressed as gram per day/body weight. Regarding ultra-processed food groups, the highest versus the lowest tertiles of consumption of yogurts and fermented milks, cakes and pastries, as well as non-alcoholic beverages (instant coffee and cocoa, packaged juices, and other non-alcoholic drinks, excluding soft drinks) were also significantly related to incident frailty. Conclusions Consumption of ultra-processed foods is strongly associated with frailty risk in older adults.

Abstract Background Ultra-processed food intake has been associated with chronic conditions and mortality. The aim of this study was to assess the relationship between ultra-processed food intake and incident frailty in community-dwelling older adults. Methods Prospective cohort study with 1,822 individuals aged at least 60 years who were recruited during 2008–2010 in Spain. At baseline, food consumption was obtained using a validated computerized face-to-face dietary history. Ultra-processed foods were identified according to the nature and extent of their industrial processing (NOVA classification). In 2012, incident frailty was ascertained based on Fried’s criteria. Statistical analyses were performed with logistic regression and adjusted for the main potential confounders. Results After a mean follow-up of 3.5 years, 132 cases of frailty were identified. The fully adjusted risks of frailty across increasing quartiles of the percentage of total energy intake from ultra-processed foods were the following: 0.04 (0.02–0.05), 0.05 (0.03–0.07), 0.09 (0.07–0.12), and 0.11 (0.08–0.14). Results were similar when food consumption was expressed as gram per day/body weight. Regarding ultra-processed food groups, the highest versus the lowest tertiles of consumption of yogurts and fermented milks, cakes and pastries, as well as nonalcoholic beverages (instant coffee and cocoa, packaged juices, and other nonalcoholic drinks, excluding soft drinks) were also significantly related to incident frailty. Conclusions Consumption of ultra-processed foods is strongly associated with frailty risk in older adults. Substituting unprocessed or minimally processed foods for ultra-processed foods would play an important role in the prevention of age-related frailty. Trial registration NCT02804672.
