- Background: High red meat consumption is associated with an increased mortality risk. This association is partly explained by the negative effect of processed meat consumption, which is widely established. The role of nonprocessed meat is unclear. Objective: The objective was to examine the combined association of processed and nonprocessed meat consumption with survival in a Swedish large prospective cohort. Design: In a population-based cohort of 74,645 Swedish men (40,089) and women (34,556), red meat consumption was assessed through a self-administered questionnaire. We estimated differences in survival [15th percentile differences (PDs), differences in the time by which the first 15% of the cohort died] according to levels of total red meat and combined levels of processed and nonprocessed red meat consumption. Results: During 15 y of follow-up (January 1998 to December 2012), we documented 16,683 deaths (6948 women; 9735 men). Compared with no consumption, consumption of red meat >100 g/d was progressively associated with shorter survival-up to 2 y for participants consuming an average of 300 g/d (15th PD: -21 mo; 95% CI: -31, -10). Compared with no consumption, high consumption of processed red meat (100 g/d) was associated with shorter survival (15th PD: -9 mo; 95% CI: -16, -2). High and moderate intakes of nonprocessed red meat were associated with shorter survival only when accompanied by a high intake of processed red meat. Conclusions: We found that high total red meat consumption was associated with progressively shorter survival, largely because of the consumption of processed red meat. Consumption of nonprocessed red meat alone was not associated with shorter survival. The Swedish Mammography Cohort and the Cohort of Swedish Men were registered at clinicaltrials.gov as NCT01127698 and NCT01127711, respectively.

- BACKGROUND: The association between fruit and vegetable (FV) consumption and overall mortality has seldom been investigated in large cohort studies. Findings from the few available studies are inconsistent.OBJECTIVE: The objective was to examine the dose-response relation between FV consumption and mortality, in terms of both time and rate, in a large prospective cohort of Swedish men and women.DESIGN: FV consumption was assessed through a self-administrated questionnaire in a population-based cohort of 71,706 participants (38,221 men and 33,485 women) aged 45-83 y. We performed a dose-response analysis to evaluate 10th survival percentile differences (PDs) by using Laplace regression and estimated HRs by using Cox regression.RESULTS: During 13 y of follow-up, 11,439 deaths (6803 men and 4636 women) occurred in the cohort. In comparison with 5 servings FV/d, a lower consumption was progressively associated with shorter survival and higher mortality rates. Those who never consumed FV lived 3 y shorter (PD: -37 mo; 95% CI: -58, -16 mo) and had a 53% higher mortality rate (HR: 1.53; 95% CI: 1.19, 1.99) than did those who consumed 5 servings FV/d. Consideration of fruit and vegetables separately showed that those who never consumed fruit lived 19 mo shorter (PD: -19 mo; 95% CI: -29, -10 mo) than did those who ate 1 fruit/d. Participants who consumed 3 vegetables/d lived 32 mo longer than did those who never consumed vegetables (PD: 32 mo; 96% CI: 13, 51 mo).CONCLUSION: FV consumption <5 servings/d is associated with progressively shorter survival and higher mortality rates. The Swedish Mammography Cohort and the Cohort of Swedish Men were registered at clinicaltrials.gov as NCT01127698 and NCT01127711, respectively.

- Beneficial effects of Mediterranean diet (MD) have been consistently documented. However, to fully understand the public health implications of MD adherence, an informative step is to quantify these effects in terms of survival time differences. The aim of this study was to evaluate the impact of MD on survival, presenting results in terms of differences in median age at death. We used data from 71,333 participants from a large population-based cohort of Swedish men and women, followed-up between January 1, 1998, and December 31, 2012. A total score of MD, ranging from 0 to 8, was calculated by including information on vegetables and fruits consumption, legumes and nuts, non-refined/high fiber grains, fermented dairy products, fish, red meat, use of olive oil/rapeseed oil, and moderate alcohol intake. Multivariable-adjusted differences in median age at death were estimated with Laplace regression and presented as a function of the MD score. During 15 years of follow-up we documented 14,697 deaths. We observed a linear dose-response association between the MD score and median age at death, with higher score associated with longer survival. The difference in median age at death between participants with the extreme scores (0 vs 8) of MD was up to 2 years (23 months, 95 % CI: 16-29). In this study we documented that adherence to MD may accrue benefits up to 2 years of longer survival.

Tidskriftsartikel (refereegranskat)abstract
- A Mediterranean diet, known to have beneficial effects on cardiovascular health, may also influence the risk of hip fracture although previous studies present discrepant results. We therefore aimed to determine whether the rate of hip fracture was associated with degree of adherence to a Mediterranean diet. We combined two Swedish cohort studies consisting of 37,903 men and 33,403 women (total n = 71,333, mean age 60 years) free of previous cardiovascular disease and cancer who answered a medical and a food-frequency questionnaire in 1997. A modified Mediterranean diet score (mMED; range, 0 to 8 points) was created based on high consumption of fruits and vegetables, legumes and nuts, whole grains, fermented dairy products, fish, and olive/rapeseed oil, moderate intake of alcohol, and low intake of red and processed meat. Incident hip fractures between January 1, 1998, and December 31, 2012, were retrieved from the National Patient Register. Hazard ratios (HRs) and 95% confidence intervals (CIs) adjusted for potential confounders were calculated using Cox proportional hazards regression. Differences in age at hip fracture were calculated using multivariable Laplace regression. During follow-up, 3175 hip fractures occurred at a median age of 73.3 years. One unit increase in the mMED was associated with 6% lower hip fracture rate (adjusted HR = 0.94; 95% CI, 0.92 to 0.96) and with a 3-month higher median age at hip fracture (50th percentile difference = 2.8 months; 95% CI, 1.4 to 4.2). Comparing the highest quintile of adherence to the mMED (6 to 8 points) with the lowest (0 to 2 points) conferred an adjusted HR of hip fracture of 0.78 (95% CI, 0.69 to 0.89) and a 12-month higher median age of hip fracture (50th percentile difference = 11.6 months; 95% CI, 4.2 to 19.0). Results were similar in men and women. We conclude that higher adherence to a Mediterranean-like diet is associated with lower risk of future hip fracture.

Forskningsöversikt (refereegranskat)abstract
- Several studies have analyzed the relationship between coffee consumption and mortality, but the shape of the association remains unclear. We conducted a dose-response meta-analysis of prospective studies to examine the dose-response associations between coffee consumption and mortality from all causes, cardiovascular disease (CVD), and all cancers. Pertinent studies, published between 1966 and 2013, were identified by searching PubMed and by reviewing the reference lists of the selected articles. Prospective studies in which investigators reported relative risks of mortality from all causes, CVD, and all cancers for 3 or more categories of coffee consumption were eligible. Results from individual studies were pooled using a random-effects model. Twenty-one prospective studies, with 121,915 deaths and 997,464 participants, met the inclusion criteria. There was strong evidence of nonlinear associations between coffee consumption and mortality for all causes and CVD (P for nonlinearity < 0.001). The largest risk reductions were observed for 4 cups/day for all-cause mortality (16%, 95% confidence interval: 13, 18) and 3 cups/day for CVD mortality (21%, 95% confidence interval: 16, 26). Coffee consumption was not associated with cancer mortality. Findings from this meta-analysis indicate that coffee consumption is inversely associated with all-cause and CVD mortality.

- BACKGROUND/OBJECTIVES: Several epidemiological studies have analyzed the associations between red and processed meat and bladder cancer risk but the shape and strength of the associations are still unclear. Therefore, we conducted a dose-response meta-analysis to quantify the potential association between red and processed meat and bladder cancer risk.METHODS: Relevant studies were identified by searching the PubMed database through January 2016 and reviewing the reference lists of the retrieved articles. Results were combined using random-effects models.RESULTS: Five cohort studies with 3262 cases and 1,038,787 participants and 8 cases-control studies with 7009 cases and 27,240 participants met the inclusion criteria. Red meat was linearly associated with bladder cancer risk in case-control studies, with a pooled RR of 1.51 (95% confidence interval (CI) 1.13, 2.02) for every 100 g increase per day, while no association was observed among cohort studies (P heterogeneity across study design = 0.02). Based on both case-control and cohort studies, the pooled relative risk (RR) for every 50 g increase of processed meat per day was 1.20 (95% CI 1.06, 1.37) (P heterogeneity across study design = 0.22).CONCLUSIONS: This meta-analysis suggests that processed meat may be positively associated with bladder cancer risk. A positive association between red meat and risk of bladder cancer was observed only in case-control studies, while no association was observe in prospective studies.

- BACKGROUND: Antioxidants present in fruits and vegetables may protect the lung from oxidative damage and prevent COPD.AIMS: To determine the association between fruit and vegetable consumption and risk of COPD by smoking status in men.METHODS: The population-based prospective Cohort of Swedish Men included 44 335 men, aged 45-79 years, with no history of COPD at baseline. Fruit and vegetable consumption was assessed with a self-administered questionnaire.RESULTS: During a mean follow-up of 13.2 years, 1918 incident cases of COPD were ascertained. A strong inverse association between total fruit and vegetable consumption and COPD was observed in smokers but not in never-smokers (p-interaction=0.02). The age-standardised incidence rate per 100 000 person-years in the lowest quintile (<2 servings/day) of total fruit and vegetable consumption was 1166 in current smokers and 506 in ex-smokers; among those in the highest quintile (≥5.3 servings/day), 546 and 255 per 100 000 person-years, respectively. The multivariable HR of COPD comparing extreme quintiles of total fruit and vegetable consumption was 0.60 (95% CI 0.47 to 0.76, p-trend <0.0001) in current smokers and 0.66 (95% CI 0.51 to 0.85, p-trend=0.001) in ex-smokers. Each one serving per day increment in total fruit and vegetable consumption decreased risk of COPD significantly by 8% (95% CI 4% to 11%) in current smokers and by 4% (95% CI 0% to 7%) in ex-smokers.CONCLUSIONS: These results indicate that high consumption of fruits and vegetables is associated with reduced COPD incidence in both current and ex-smokers but not in never-smokers.

- AIMS: The aim of this study was to conduct a meta-analysis of prospective studies assessing the relationship between alcohol consumption and risk of heart failure (HF).METHODS AND RESULTS: We searched the PubMed database from inception to September 2014 and reviewed the reference list of relevant articles to identify prospective studies assessing the association between alcohol consumption and risk of HF. Study-specific relative risk (RR) estimates were combined using a random-effects meta-analysis. The meta-analysis included eight prospective studies, with a total of 202 378 participants and 6211 cases of HF. The pooled adjusted RRs of HF were 0.85 [95% confidence interval (CI) 0.78-0.93] for light to moderate alcohol consumption (<14 drinks/week) and 0.90 (95% CI 0.72-1.13) for high alcohol consumption (≥14 drinks/week) compared with non-drinkers. In a dose-response meta-analysis, we observed a non-linear relationship between alcohol consumption and risk of HF (P for non-linearity = 0.001). Compared with non-drinkers, the RRs (95% CI) across levels of alcohol consumption were 0.90 (0.84-0.96) for 3 drinks/week, 0.83 (0.73-0.95) for 7 drinks/week, 0.84 (0.72-0.98) for 10 drinks/week, 0.90 (0.73-1.10) for 14 drinks/week, and 1.07 (0.77-1.48) for 21 drinks/week.CONCLUSION: Alcohol consumption in moderation is associated with a reduced risk of HF.

- A number of studies have examined the association between body mass index (BMI) and risk of pancreatic cancer, but uncertainty about the relationship remains. We performed a meta-analysis to summarize the evidence from prospective studies investigating this association. We searched MEDLINE for studies published in any language from 1966 to November 2006. Prospective studies were included if they reported relative risks (RRs) with 95% confidence intervals (CIs) for the association between BMI and pancreatic cancer incidence or mortality. Study-specific RR estimates were combined by use of a random-effects model. A total of 21 independent prospective studies, involving 3,495,981 individuals and 8,062 pancreatic cancer cases, met the inclusion criteria. The estimated summary RR of pancreatic cancer per 5 kg/m(2) increase in BMT was 1.12 (95% CI, 1.06-1.17; p-heterogeneity = 0.13) in men and women combined, 1.16 (95% CI, 1.05-1.28; p-heterogeneity = 0.001) in men, and 1.10 (95% CI, 1.02-1.19; p-heterogeneity = 0.12) in women. There was no evidence of publication bias (p = 0.58). Findings from this meta-analysis of prospective studies support a positive association between BMI and risk of pancreatic cancer in men and women. (c) 2007 Wilely-Liss, Inc.

- Coffee consumption is associated with a reduced risk of several diseases but uncertainty remains about the influence of coffee consumption on the risk of dementia. We performed a dose-response meta-analysis to summarize the prospective data on coffee consumption and associated risk of dementia and Alzheimer's disease. We identified studies by searching PubMed (from January 1966) and Web of Science (from January 1945) through 4 October 2018 and by scrutinizing the reference lists of pertinent publications. Two researchers independently reviewed the literature. Results were combined using a restricted cubic spline random-effects dose-response meta-analysis based on a one-stage approach. Eight relevant prospective studies were identified. These studies included 7486 dementia cases diagnosed among 328,885 individuals during an average follow-up of 4.9⁻25 years. Meta-analysis of all eight studies indicated no statistically significant association between coffee consumption and the risk of dementia and no deviations from a linear trend (p = 0.08). The relative risk of dementia per 1 cup/day increment of coffee consumption was 1.01 (95% confidence interval (CI) 0.98⁻1.05; p = 0.37). Meta-analysis of five studies that focused on Alzheimer's disease revealed no association between coffee consumption and Alzheimer's disease and no deviations from a linear trend (p = 0.79). The relative risk of Alzheimer's disease per 1 cup/day increment of coffee consumption was 1.01 (95% confidence interval 0.95⁻1.07; p = 0.80). These results do not support an association between coffee consumption and an increased risk of overall dementia or Alzheimer's disease specifically, but further research on the association of coffee consumption with dementia risk is needed.
