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<\/i>.<\/p>\n
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.<\/p>\n
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.<\/p>\n
“Future studies exploring the potential benefits of a whole dietary approach in the hemodialysis setting are also warranted,” the authors write.<\/p>\n
The study was funded by Diaverum, a provider of renal services; several authors are employees of Diaverum.<\/p>\n
