ObjectiveCurrent evidence of the associations between cardiorespiratory fitness (CRF) and mortality is limited. We performed a meta-analysis to assess the dose–response association of CRF with mortality from all causes, cardiovascular disease (CVD) and cancer in healthy population.MethodsPubMed, EMBASE and Web of Science were searched up to 26 December 2019 for reports of cohort studies giving risk estimates for all-cause, CVD and cancer mortality by level of CRF. Cohort studies were included if CRF was assessed by an exercise stress test and reported as at least three levels or per incremental increase, and the association of CRF with all-cause, CVD and cancer mortality was evaluated. Generalised least-squares regression models were used to assess the quantitative relation of CRF with all-cause, CVD and cancer mortality.Results34 cohort studies were eligible for the meta-analysis. The pooled relative risks (RRs) for all-cause, CVD and cancer mortality per one-metabolic equivalent increase in CRF were 0.88 (95% CI 0.83 to 0.93), 0.87 (95% CI0.83 to 0.91) and 0.93 (95% CI 0.91 to 0.96), respectively. As compared with lowest CRF, with intermediate CRF, the summary RRs for all-cause, CVD and cancer mortality were 0.67 (95% CI 0.61 to 0.74), 0.60 (95% CI 0.51 to 0.69) and 0.76 (95% CI 0.69 to 0.84), respectively, and with highest CRF were 0.47 (95% CI 0.39 to 0.56), 0.49 (95% CI 0.42 to 0.56) and 0.57 (95% CI 0.46 to 0.70), respectively.ConclusionOur analysis showed inverse dose–response associations of CRF with all-cause, CVD and cancer mortality, which provides evidence for public health recommendations for preventing all-cause, CVD and cancer mortality.PROSPERO registration numberCRD42020208883.

AbstractObjectiveTo examine and quantify the potential dose-response relation between intake of total, animal, and plant protein and the risk of mortality from all causes, cardiovascular disease, and cancer.DesignSystematic review and meta-analysis of prospective cohort studies.Data sourcesPubMed, Scopus, and ISI Web of Science until December 2019, and references of retrieved relevant articles.Study selectionProspective cohort studies that reported the risk estimates for all cause, cardiovascular, and cancer mortality in adults aged 18 or older.Data synthesisRandom effects models were used to calculate pooled effect sizes and 95% confidence intervals for the highest versus lowest categories of protein intake and to incorporate variation between studies. Linear and non-linear dose-response analyses were done to evaluate the dose-response relations between protein intake and mortality.Results32 prospective cohort studies were included in the systematic review and 31 in the meta-analysis. During the follow-up period of 3.5 to 32 years, 113 039 deaths (16 429‬ from cardiovascular disease and 22 303‬ from cancer) occurred among 715 128 participants. Intake of total protein was associated with a lower risk of all cause mortality (pooled effect size 0.94, 95% confidence interval 0.89 to 0.99, I2=58.4%, P<0.001). Intake of plant protein was significantly associated with a lower risk of all cause mortality (pooled effect size 0.92, 95% confidence interval 0.87 to 0.97, I2=57.5%, P=0.003) and cardiovascular disease mortality (pooled hazard ratio 0.88, 95% confidence interval 0.80 to 0.96, I2=63.7%, P=0.001), but not with cancer mortality. Intake of total and animal protein was not significantly associated with risk of cardiovascular disease and cancer mortality. A dose-response analysis showed a significant inverse dose-response association between intake of plant protein and all cause mortality (P=0.05 for non-linearity). An additional 3% energy from plant proteins a day was associated with a 5% lower risk of death from all causes.ConclusionsHigher intake of total protein was associated with a lower risk of all cause mortality, and intake of plant protein was associated with a lower risk of all cause and cardiovascular disease mortality. Replacement of foods high in animal protein with plant protein sources could be associated with longevity.

Introduction: Whole grain intake has been associated with lower risks of multiple chronic conditions, but its association with mortality warrants further evaluation. Hypothesis: We performed a meta-analysis of prospective cohort studies on the association of whole grain intake with all-cause and cause-specific mortality, and tested the hypothesis that they followed inverse dose-response pattern. Methods: Published studies reporting relative risks (RRs) between whole grain consumption and mortality from Medline and Embase through August, 2015. Original results from National Health and Nutrition Examination Survey (NHANES) III and NHANES 1999-2004 were included. Whole grain ingredients (gram/day) were estimated among studies reporting RRs for ≥3 categories of whole grain intake. Results: Fourteen unique analyses were included, which consisted of 786,076 participants, 97,867 all-cause deaths, 23,957 CVD deaths, and 37,492 cancer deaths. Pooled RRs (95% confidence intervals) comparing high with low whole grain categories were 0.84 (0.80, 0.88; P <0.001, I2=74%, P heterogeneity<0.001) for all-cause mortality, 0.82 (0.79, 0.85; P <0.001, I2=0%, P heterogeneity=0.53) for CVD mortality, and 0.88(0.83, 0.94; P <0.001, I2=54%, P heterogeneity=0.02) for cancer mortality. Whole grain consumption was <50 grams/day among most studies. Dose-response meta-analysis showed strong monotonic associations between whole grain and mortality (All P nonlinearity > 0.05): RRs (95%CIs) for each 16 grams/day increase (approximately 1 serving/day) in whole grain were 0.93(0.92, 0.94) for all-cause mortality, 0.91(0.90, 0.93) for CVD mortality, and 0.95(0.94, 0.96) for cancer mortality. These findings were robust in several stratified analyses and/or sensitivity analyses. Egger’s test did not suggest significant publication bias. Conclusions: Our findings supported health benefit of increasing current whole grain intake of <1 serving/day to ≥3 servings/day as recommended by current Dietary Guidelines for Americans.
