- Background/objectives Whole-grain (WG) intake has been associated with a lowered risk of developing type 2 diabetes, cardiovascular disease, and some cancers in epidemiological studies. Reduced subclinical inflammation could be one important mechanism behind such associations. This study investigated whether high long-term WG rye and wheat intakes were associated with lower concentrations of biomarkers of inflammation, endothelial function, and protein biomarkers associated with cardiovascular disease. Subjects/methods We assessed WG intake by food frequency questionnaire (FFQ) and by measuring alkylresorcinols (ARs) in plasma and adipose tissue, respectively. Selected biomarkers in free-living 109 women and 149 men were analyzed from two clinical subcohort studies (Swedish Mammography Cohort-Clinical (SMC-C) and Cohort of Swedish Men-Clinical (COSM-C), respectively. Total WG rye and wheat (WGRnW) and the ratio of WG rye to WG rye and wheat (WGR/WGRnW) were estimated from FFQs. ARs were measured in plasma and adipose tissue by gas chromatography-mass spectrometry (GC-MS) and the biomarkers by ELISA. Results We found no consistent associations between WG intake assessed by different methods and the selected biomarkers. However, WGRnW intake was inversely associated with cathepsin S (P-trend < 0.05) and total AR and C17:0/C21:0 in plasma were inversely associated with the endostatin concentration (P-trend < 0.05) adjusted for BMI, age, and sex. Conclusion The results give limited support to the hypothesis that a high WG wheat and rye intake is associated with lower concentrations of common biomarkers of inflammation and CVD that have previously been reported inversely associated with WG intake or an overall healthy lifestyle.

- BACKGROUND: Body mass index (BMI) and diabetes are established risk factors for colorectal cancer (CRC), likely through perturbations in metabolic traits (e.g. insulin resistance and glucose homeostasis). Identification of interactions between variation in genes and these metabolic risk factors may identify novel biologic insights into CRC etiology.METHODS: To improve statistical power and interpretation for gene-environment interaction (G × E) testing, we tested genetic variants that regulate expression of a gene together for interaction with BMI (kg/m2 ) and diabetes on CRC risk among 26 017 cases and 20 692 controls. Each variant was weighted based on PrediXcan analysis of gene expression data from colon tissue generated in the Genotype-Tissue Expression Project for all genes with heritability ≥1%. We used a mixed-effects model to jointly measure the G × E interaction in a gene by partitioning the interactions into the predicted gene expression levels (fixed effects), and residual G × E effects (random effects). G × BMI analyses were stratified by sex as BMI-CRC associations differ by sex. We used false discovery rates to account for multiple comparisons and reported all results with FDR <0.2.RESULTS: Among 4839 genes tested, genetically predicted expressions of FOXA1 (P = 3.15 × 10-5 ), PSMC5 (P = 4.51 × 10-4 ) and CD33 (P = 2.71 × 10-4 ) modified the association of BMI on CRC risk for men; KIAA0753 (P = 2.29 × 10-5 ) and SCN1B (P = 2.76 × 10-4 ) modified the association of BMI on CRC risk for women; and PTPN2 modified the association between diabetes and CRC risk in both sexes (P = 2.31 × 10-5 ).CONCLUSIONS: Aggregating G × E interactions and incorporating functional information, we discovered novel genes that may interact with BMI and diabetes on CRC risk.

- Background: Vitamin D status is known to be important for bone health but may also affect the development of several chronic diseases, including cancer and cardiovascular diseases, which are 2 major causes of death. Objective: We aimed to examine how vitamin D status relates to overall and cause-specific mortality. Design: The Uppsala Longitudinal Study of Adult Men, a community-based cohort of elderly men (mean age at baseline: 71 y; n = 1194), was used to investigate the association between plasma 25-hydroxyvitamin D [25(OH)D] and mortality. Total plasma 25(OH)D was determined with HPLC atmospheric pressure chemical ionization mass spectrometry. Proportional hazards regression was used to compute hazard ratios (HRs). Results: During follow-up (median: 12.7 y), 584 (49%) participants died. There was a U-shaped association between vitamin D concentrations and total mortality. An approximately 50% higher total mortality rate was observed among men in the lowest 10% (<46 nmol/L) and the highest 5% (>98 nmol/L) of plasma 25(OH)D concentrations compared with intermediate concentrations. Cancer mortality was also higher at low plasma concentrations (multivariable-adjusted HR: 2.20; 95% CI: 1.44, 3.38) and at high concentrations (HR: 2.64; 95% CI: 1.46, 4.78). For cardiovascular death, only low (HR: 1.89; 95% CI: 1.21, 2.96) but not high (HR: 1.33; 95% CI: 0.69, 2.54) concentrations indicated higher risk. Conclusions: Both high and low concentrations of plasma 25(OH)D are associated with elevated risks of overall and cancer mortality. Low concentrations are associated with cardiovascular mortality.

- The role of fruit and vegetable intake in relation to fracture prevention during adulthood and beyond is not adequately understood. We investigated the potential association between fruit and vegetable intake and hip fracture incidence in a large sample of elderly from Europe and United States. A total of 142,018 individuals (among which 116,509 women), aged ≥60 years old, from five cohorts, were followed-up prospectively for 1,911,482 person-years accumulating 5,552 hip fractures. Fruit and vegetable intake was assessed by validated, cohort-specific, food-frequency questionnaires. Ηip fractures were ascertained through national patient registers or telephone interviews/questionnaires. Adjusted hazard ratios (HR) derived by Cox proportional-hazards regression were estimated for each cohort and subsequently pooled using random-effects meta-analysis. Intake of ≤ 1 servings/day of fruit and vegetables combined was associated with 39% higher hip fracture risk [pooled adjusted HR:1.39, 95% Confidence Intervals (CIs): 1.20, 1.58] in comparison to moderate intake (>3 and ≤5 servings/day) (pfor heterogeneity = 0.505), whereas higher intakes (>5 servings/day) were not associated with lower risk in comparison to the same reference. Associations were more evident among women. We concluded that a daily intake of one or less servings of fruits and vegetables was associated with increased hip fracture risk in relation to moderate daily intakes. Older adults with such low fruit and vegetable consumption may benefit from raising their intakes to moderate amounts in order to reduce their hip fracture risk.

- The association between adherence to Mediterranean diet (MD) and hip fracture incidence is not yet established. In a diverse population of elderly, increased adherence to MD was associated with lower hip fracture incidence. Except preventing major chronic diseases, adhering to MD might have additional benefits in lowering hip fracture risk.INTRODUCTION: Hip fractures constitute a major public health problem among older adults. Latest evidence links adherence to Mediterranean diet (MD) with reduced hip fracture risk, but still more research is needed to elucidate this relationship. The potential association of adherence to MD with hip fracture incidence was explored among older adults.METHODS: A total of 140,775 adults (116,176 women, 24,599 men) 60 years and older, from five cohorts from Europe and the USA, were followed-up for 1,896,219 person-years experiencing 5454 hip fractures. Diet was assessed at baseline by validated, cohort-specific, food-frequency questionnaires, and hip fractures were ascertained through patient registers or telephone interviews/questionnaires. Adherence to MD was evaluated by a scoring system on a 10-point scale modified to be applied also to non-Mediterranean populations. In order to evaluate the association between MD and hip fracture incidence, cohort-specific hazard ratios (HR), adjusted for potential confounders, were estimated using Cox proportional-hazards regression and pooled estimates were subsequently derived implementing random-effects meta-analysis.RESULTS: A two-point increase in the score was associated with a significant 4% decrease in hip fracture risk (pooled adjusted HR 0.96; 95% confidence interval (95% CI) 0.92-0.99, pheterogeneity = 0.446). In categorical analyses, hip fracture risk was lower among men and women with moderate (HR 0.93; 95% CI 0.87-0.99) and high (HR 0.94; 95% CI 0.87-1.01) adherence to the score compared with those with low adherence.CONCLUSIONS: In this large sample of older adults from Europe and the USA, increased adherence to MD was associated with lower hip fracture incidence.

- Background Tea has the potential to lower the risk of abdominal aortic aneurysm (AAA) owing to its high antioxidant capacity. AAA risk factors including smoking, hypertension, and hypercholesterolaemia, may modify this association. Methods The study population included 45 047 men in the Cohort of Swedish Men (COSM) and 36 611 women in the Swedish Mammography Cohort (SMC), aged 45-83 years at baseline. The COSM was established in 1997 with all men who lived in two central Swedish counties (Vastmanland and orebro), and the SMC was established in 1987-1990 with women residing in Vastmanland county. Tea consumption was assessed by means of food frequency questionnaires in 1997 and 2009. Results During 17.5 years of follow-up, 1781 AAA cases (1496 men, 285 women; 1497 non-ruptured, 284 ruptured) were ascertained via Swedish registers. Tea consumption was inversely associated with total AAA incidence in men and women. Women had a 23 (95 per cent c.i. 8 to 36) per cent lower risk of AAA per each cup per day increment, whereas men had a 9 (0 to 17) per cent lower risk (P-interaction = 0.029). Tea consumption was associated with a lower risk of both non-ruptured (hazard ratio (HR) 0.93, 95 per cent c.i. 0.85 to 1.01) and ruptured (HR 0.84, 0.71 to 0.98) AAA. Smoking status modified the association (P-interaction < 0.001), whereby tea consumption was associated with lower risk of AAA in ex-smokers (per cup per day, HR 0.89, 0.80 to 0.98) and in never smokers (HR 0.88, 0.77 to 1.00), but not in current smokers (HR 0.95, 0.84 to 1.06). Tea consumption was associated with a lower risk in participants with (HR 0.88, 0.80 to 0.98) and without (HR 0.93, 0.88 to 1.00) hypertension, and in those with (HR 0.82, 0.67 to 1.01) and without (HR 0.92, 0.86 to 0.98) hypercholesterolaemia. Conclusion Tea consumption was associated with a reduced risk of AAA. The association was more pronounced for ruptured than non-ruptured AAA, and in patients with hypertension and hypercholesterolaemia than those without. The association was also observed in ex-smokers and never smokers, but not in current smokers. The results of the study suggest that tea consumption may be associated with a reduced risk of abdominal aortic aneurysm (ruptured and non-ruptured) in men and women, in participants with and without hypertension and hypercholesterolaemia, and in never and ex-smokers but not in current smokers. Tea consumption has the potential for the prevention of abdominal aortic aneurysm and, in addition to quitting smoking, a healthy diet including tea could help reduce this risk.

- Purpose: Our aim was examine the association between black tea consumption and risk of total stroke and stroke types in a prospective study. Methods: A total of 74,961 Swedish women and men who were free of cardiovascular disease and cancer at baseline in 1997 were followed up through December 2008. Tea consumption was assessed with a questionnaire at baseline. Stroke cases were ascertained from the Swedish Hospital Discharge Registry. Results: During a mean follow-up of 10.2 years, we ascertained 4089 cases of first stroke, including 3159 cerebral infarctions, 435 intracerebral hemorrhages, 148 subarachnoid hemorrhages, and 347 unspecified strokes. After adjustment for other risk factors, high tea consumption was associated with a significantly lower risk of total stroke; however, there was no dose response relation (P for trend = .36). Compared with no tea consumption, the multivariable relative risk for four or more cups per day (median, 5) was 0.79 (95% confidence interval [CI], 0.62-0.998). The corresponding relative risks were 0.80 (95% CI, 0.61-1.04) for cerebral infarction and 0.68 (95% Cl, 0.35-1.30) for hemorrhagic stroke. Conclusions: These findings suggest that daily consumption of four or more cups of black tea is inversely associated with risk of stroke. (C) 2013 Elsevier Inc. All rights reserved.

- Objective: To investigate the association between chocolate consumption and risk of stroke in men and conduct a meta-analysis to summarize available evidence from prospective studies of chocolate consumption and stroke. Methods: We prospectively followed 37,103 men in the Cohort of Swedish Men. Chocolate consumption was assessed at baseline using a food-frequency questionnaire. Cases of first stroke were ascertained from the Swedish Hospital Discharge Registry. For the meta-analysis, pertinent studies were identified by searching the PubMed and EMBASE databases through January 13, 2012. Study-specific results were combined using a random-effects model. Results: During 10.2 years of follow-up, we ascertained 1,995 incident stroke cases, including 1,511 cerebral infarctions, 321 hemorrhagic strokes, and 163 unspecified strokes. High chocolate consumption was associated with a lower risk of stroke. The multivariable relative risk of stroke comparing the highest quartile of chocolate consumption (median 62.9 g/week) with the lowest quartile (median 0 g/week) was 0.83 (95% CI 0.70-0.99). The association did not differ by stroke subtypes. In a meta-analysis of 5 studies, with a total of 4,260 stroke cases, the overall relative risk of stroke for the highest vs lowest category of chocolate consumption was 0.81 (95% CI 0.73-0.90), without heterogeneity among studies (p = 0.47). Conclusion: These findings suggest that moderate chocolate consumption may lower the risk of stroke. Neurology (R) 2012;79:1223-1229

- OBJECTIVE: Experimental findings and previous observational data have suggested lower risk of osteoarthritis (OA) with statin use but results are inconsistent. Large-scale studies with a clinically important outcome are needed. Thus, we aimed to determine whether statin use is associated with a reduced risk of developing clinically-defined hip or knee OA.DESIGN: Pooled analysis based on time-to-event analysis of four population-based large cohorts, encompassing in total 132,607 persons aged 57-91 years resident in southern and central Sweden. We studied the association between statin use and time to consultation or surgery for OA of the hip or knee by time-dependent exposure analysis and Cox regression.RESULTS: During 7.5 years of follow-up, we identified 7468 out- or inpatient treated cases of hip or knee OA. Compared with never use, current use of statins conferred no overall reduction in the risk of OA with an adjusted pooled hazard ratio (HR) of 1.04 (95% confidence intervals [95% CI] 0.99-1.10). We found no dose-response relation between duration of current statin use and the risk of OA, with similar HRs among patients with less than 1 year of use (HR 1.09; 95% CI 0.92-1.32) as in patients with use for 3 years or more (HR 1.05; 0.93-1.16). Results were comparable in those with low, medium and high dose of current statin use, without indications of heterogeneity of study results.CONCLUSION: Statin use is not associated with reduced risk of consultation or surgery for OA of the hip or knee.

- BACKGROUND & AIMS: There is conflicting epidemiologic evidence on whether coffee consumption reduces the risk of gallstone disease. We examined the association between coffee consumption and risk of cholecystectomy (as a proxy for symptomatic gallstone disease) in a prospective cohort study. METHODS: We collected data from 30,989 women (born 1914-1948) and 40,936 men (born 1918-1952) from the Swedish Mammography Cohort and the Cohort of Swedish Men. Baseline information on coffee consumption was collected by using a food-frequency questionnaire; subjects were followed up for procedures of cholecystectomy from 1998 through 2011 by linkage to the Swedish Patient Register. Hazard ratios (HRs) were estimated by using Cox proportional hazard models. RESULTS: During a total follow-up period of 905,933 person-years, we identified 1057 women and 962 men who had undergone a cholecystectomy. After adjustment for potential confounders, the HR of cholecystectomy was 0.58 (95% confidence interval [CI], 0.44-0.78) for women who drank >= 6 cups of coffee/day compared with women who drank < 2 cups/day. In contrast, there was no association in men (HR, 0.96; 95% CI, 0.75-1.24). Because of this sex difference, we examined and found evidence of effect modification by menopausal status and use of hormone replacement therapy (HRT) (P-interaction = .026). An inverse association was observed only in women who were premenopausal (HR, 0.17; 95% CI, 0.05-0.55) or used HRT (HR, 0.44; 95% CI, 0.28-0.70). CONCLUSIONS: We observed an inverse association between coffee consumption and risk of cholecystectomy in women who were premenopausal or used HRT but not in other women or in men.
