Adherence to a Western dietary pattern and risk of bladder cancer: A pooled analysis of 13 cohort studies of the Bladder Cancer Epidemiology and Nutritional Determinants international study

Abstract

Little is known about the association of diet with risk of bladder cancer. This might be due to the fact that the majority of studies have focused on single food items, rather than dietary patterns, which may better capture any influence of diet on bladder cancer risk. We aimed to investigate the association between a measure of Western dietary pattern and bladder cancer risk. Associations between adherence to a Western dietary pattern and risk of developing bladder cancer were assessed by pooling data from 13 prospective cohort studies in the "BLadder cancer Epidemiology and Nutritional Determinants" (BLEND) study and applying Cox regression analysis. Dietary data from 580 768 study participants, including 3401 incident cases, and 577 367 noncases were analyzed. A direct and significant association was observed between higher adherence to a Western dietary pattern and risk of bladder cancer (hazard ratio (HR) comparing highest with lowest tertile scores: 1.54, 95% confidence interval (CI): 1.37, 1.72; P-trend = .001). This association was observed for men (HR comparing highest with lowest tertile scores: 1.72; 95% CI: 1.51, 1.96; P-trend = .001), but not women (P-het = .001). Results were consistent with HR above 1.00 after stratification on cancer subtypes (nonmuscle-invasive and muscle-invasive bladder cancer). We found evidence that adherence to a Western dietary pattern is associated with an increased risk of bladder cancer for men but not women.

Dietary patterns and risk of bladder cancer: a systematic review and meta-analysis

“…Some were excluded because of duplication and being irrelevant articles. Eventually, seven cohort studies [ 10 , 11 , 14 – 17 , 34 ], and five case control studies [ 9 , 12 , 13 , 35 , 36 ] were included in the present mete-analysis. Included cohort studies consisted of 12,679 cases and 1,952,859 non-cases.…”

“…Of the Included articles that were published between 2008 and 2020, six studies assessed the effect of MD on BC risk [ 12 – 17 ], three articles investigated the associations between WD and BC [ 9 – 11 ], and three studied on DII and BC [ 34 – 36 ]. Two of them were conducted in Italy [ 12 , 35 ] and others were conducted in Netherlands [ 15 ], two from EPIC study [ 14 , 16 ], Belgium [ 13 ], Australia [ 17 ], Uruguay[ 9 ], Iran [ 36 ], united states [ 11 , 34 ], and one from Australia, European countries and united states [ 10 ]. Dietary intake was assessed using food-frequency questionnaire (FFQ) in almost all the included studies.…”

An integrative review of comprehensive nursing assessment tools developed based on Gordon's Eleven Functional Health Patterns

“…Nutrition-Metabolic Pattern: The pattern of food and fluid consumption varies widely according socioeconomic status, habits, culture, and health status, and have been linked to health outcomes (Dianatinasab et al, 2020;Lee et al, 2017;Teixeira et al, 2019). However, nutrition assessment was found to be largely neglected in nursing assessment, in particular, energy intake and body mass index (Lorenzon et al, 2020;Persenius et al, 2008).…”

Analysis of Fat Content with Special Emphasis on Trans Isomers in Frequently Consumed Food Products in Egypt: The First Steps in the Trans Fatty Acid Elimination Roadmap

“…The same observation was noted with oriental sweets, where the content surpassed that of doughnuts. Western dietary patterns have been associated with increased risks of NCDs among youth and adults compared to Mediterranean dietary patterns [ 21 , 22 , 23 , 24 , 25 ]. However, this study highlights that some traditional items consumed in the diets of the Mediterranean region may be more harmful than Western food items and do not fit in the Mediterranean dietary pattern.…”
