Emerging evidence suggests that diet and renal function are related. Little is known, however, about the association of consumption of whole grains, fruit and vegetables with urinary albumin:creatinine ratio (ACR) and changes in estimated glomerular filtration rate (eGFR). We investigated this in a population-based cohort aged 26-65 years. Data were from 3787 participants from the Doetinchem cohort study, who were examined ≥3 times, 5 years apart. Consumption of food groups was assessed at each round with a validated FFQ. GFR was estimated at each round from routinely measured cystatin C and creatinine using the Chronic Kidney Disease-Epidemiology (CKD-EPI) equation. ACR was measured at the last round. Generalised estimated equation models were performed to examine associations with changes in eGFR. Linear regression was used to examine associations with ACR. Adjustments were made for covariates related to lifestyle, biological factors and diet. Mean baseline eGFR was 104·5 (SD 13·7) and mean annual decline was −0·95 (SD 0·67) ml/min per 1·73 m 2 over a 15-year follow-up. A trend was observed towards slightly less annual decline in eGFR among those with higher consumption of whole grains (P = 0·06). This association, however, was attenuated and no longer significant in multivariate models (P = 0·29). Consumption of fruit and vegetables was not associated with changes in eGFR and urinary ACR. In conclusion, consumption of whole grains, fruit and vegetables is not associated with changes in eGFR and mean ACR. As this was the first longitudinal study into this association in the general population, and as results are only partially in line with related studies, further research is recommended.
Background Irritable bowel syndrome (IBS) is a highly prevalent disorder with significant negative impact on quality of life of patients that results in high healthcare use and costs. Improving healthcare outcomes for IBS patients is warranted, however the exact needs of IBS patients with regard to therapy and control of symptoms are unknown. Methods Focus group interviews, using a two-stage model, were performed with twenty-three IBS patients meeting Rome III criteria and one mother of a patient, from four different regions from the Netherlands. Results Twenty-four participants were included of whom majority were female (n = 21), mean age was 43 years, and mean duration of IBS was 18 years. Five categories of patients’ perspectives were identified: clear communication, a multidisciplinary treatment team, centers of expertise, focus on scientific research and information about IBS that is widely available for patients. Conclusions Based on these findings we highlight the need for IBS care givers to take these key items into account in IBS care. These elements aid clinicians, but mostly patients, in coping and management of symptoms and subsequent healthcare outcomes, reducing overall healthcare use and costs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
