“…The diet assessment, reported earlier (Wirfält et al, 2002), combines quantitative and semi-quantitative approaches to the entire diet, including cooking methods (Callmer et al, 1993). It consists of two parts: a 'menu book' for description of cooked meals and registration of cold (including juices and alcoholic) beverages and dietary supplements during seven consecutive days; and a 168-item food questionnaire on regularly consumed foods during the past year.…”

A prospective Swedish study on body size, body composition, diabetes, and prostate cancer risk

Obesity may be associated with increased risk of prostate cancer (PCa). According to one hypothesis, obesity could lower the risk of non-aggressive tumours, while simultaneously increasing the risk of aggressive cancer. Furthermore, central adiposity may be independently associated with PCa risk; it is also associated with diabetes, which itself may influence risk of PCa. We studied the associations between height, body composition, and fat distribution, diabetes prevalence and risk of total, aggressive, and nonaggressive PCa in 10 564 initially cancer-free men (aged 45 -73 years) of the population-based Malmö Diet and Cancer cohort. Anthropometric and body composition measurements, including bioelectrical impedance for estimation of fat mass, were performed by study nurses. Diabetes prevalence was self-reported. Cancer cases and clinical characteristics were ascertained through national and regional registry data. Dietary and other background data were obtained through a modified diet history method and an extensive questionnaire. During a mean follow-up of 11.0 years, 817 incidental PCa cases were diagnosed. Of these, 281 were classified as aggressive. There were 202 cases occurring before 65 years of age. Height was positively associated with total and nonaggressive PCa risk. Waist -hip ratio (WHR), a measure of central adiposity, was positively associated with PCa before age 65, and less strongly, with total PCa. This association was independent of body mass index (BMI) and other potential confounders. General adiposity, expressed as BMI or body fat percentage, and prevalent diabetes were not associated with PCa risk. In this study, WHR and body height were stronger PCa predictors than general adiposity.

“…The food intake was converted to energy and nutrient intakes using the MDC nutrient database in which the majority of the nutrient information comes from PC-KOST2-93 from the National Food Administration in Uppsala, Sweden. The MDC method is described in detail elsewhere (21,22). Nutrient intakes from supplements were calculated based on registration of supplement consumption in the menu book.…”

Background: Single nucleotide polymorphisms (SNP) of the folate-metabolizing enzyme methylenetetrahydrofolate reductase (MTHFR) may modify associations between folate intake and breast cancer. We examined if the association between tertiles of dietary folate equivalents (DFE) and breast cancer was different in subgroups according to genotypes of the MTHFR 677 C>T (rs1801133) and 1298A>C (rs1801131) SNPs and if the polymorphisms per se were associated with breast cancer.Methods: This nested case-control study included 544 incident cases with invasive breast cancer and 1,088 controls matched on age and blood sampling date from the population-based Malmö Diet and Cancer cohort. Genotyping of the MTHFR SNPs was done with PCR-based matrix-assisted laser desorption/ ionization time-of-flight mass spectrometry. Odds ratios (OR) were obtained by unconditional logistic regression.

“…This change did not reveal any major influence on the ranking of individuals. 18 The average daily intake of foods was calculated based on the information available in the menu book (and interview) and the questionnaire. The average daily food intake was converted to nutrient intake data using a database, which was specifically developed for the MDC study and originated from the Swedish National Food Administration.…”

Association between fat intake, physical activity and mortality depending on genetic variation in FTO

Objective: We wanted to explore if FTO genotype interacts with fat intake, or leisure-time physical activity, on fat mass, lean mass and mortality. Subjects and methods: Among 22 799 individuals (44-74 years) in the population-based Malmö diet and cancer cohort that were genotyped for rs9939609 in FTO and had information on dietary intake (from a modified diet history method) and no history of diabetes, cancer or cardiovascular disease, 2255 deaths (including 1100 cancer and 674 cardiovascular deaths) occurred during 12.0 years of follow-up. Leisure-time physical activity was determined from a list of 17 different physical activities in a questionnaire. Body composition was measured using bioelectric impedance method. Results: FTO genotype associated strongly with both fat mass and lean mass (P trend o1 Â 10 À16 for both) but we found only significant interactions with fat intake, or physical activity, on fat mass (P interaction ¼ 0.01 and 0.004). No significant interaction between FTO genotype and fat intake (P interaction ¼ 0.72), or leisure-time physical activity (P interaction ¼ 0.07), on total mortality were observed. However, we observed a significant interaction between leisure-time physical activity and FTO genotype on cardiovascular mortality (P interaction ¼ 0.03). The highest vs lowest quintile of physical activity was associated with 46% (95% confidence interval, 17-64%) reduced cardiovascular mortality among TT-carriers (P trend ¼ 0.004), and 11% reduced cardiovascular mortality among A-allele carriers (P trend ¼ 0.68). Conclusion: Our results indicate that FTO genotype associates with both fat mass and lean mass, but the level of fat intake and physical activity only modify the association with fat mass. In addition, FTO genotype may modify the association between physical activity and cardiovascular mortality.
