THURSDAY, Jan. 31, 2019 (HealthDay News) -- Fruit and vegetable intake is very low in the hemodialysis population, with higher consumption associated with lower mortality, according to a study published online Jan. 31 in the Clinical Journal of the American Society of Nephrology.
Valeria M. Saglimbene, from the University of Sydney, and colleagues examined the correlation between fruit and vegetable intake and mortality in hemodialysis patients in a multinational cohort study involving 9,757 adults on hemodialysis; 83 percent had analyzable dietary data.
The researchers identified 2,082 deaths (954 cardiovascular) during a median follow-up of 2.7 years. Per week, the median number of servings of fruit and vegetables was eight; only 4 percent of the study population consumed the recommended four or more servings per day. The adjusted hazard ratios for the middle (5.6 to 10; median, 8) and highest (>10; median, 17) versus the lowest (0 to 5.5; median, 2) tertile of servings per week were 0.90 (95 percent confidence interval [CI], 0.81 to 1.00) and 0.80 (95 percent CI, 0.71 to 0.91), respectively, for all-cause mortality; 0.88 (95 percent CI, 0.76 to 1.02) and 0.77 (95 percent CI, 0.66 to 0.91) for noncardiovascular mortality; and 0.95 (95 percent CI, 0.81 to 1.11) and 0.84 (95 percent CI, 0.70 to 1.00) for cardiovascular mortality.
"Future studies exploring the potential benefits of a whole dietary approach in the hemodialysis setting are also warranted," the authors write.
The study was funded by Diaverum, a provider of renal services; several authors are employees of Diaverum.
