Cvd Mortality

Background: Previous studies on intake of linoleic acid (LA), a predominant n-6 fatty acid, and risk of mortality from all-cause and cardiovascular disease (CVD) have generated inconsistent results. We performed a systematic review and meta-analysis of prospective cohort studies to summarize the evidence regarding the relation of LA and all-cause and CVD mortality. Methods: We searched MEDLINE and EMBASE databases through June 2017 for prospective cohort studies reporting association of LA (assessed by dietary survey or biomarker in blood or adipose tissue) with all-cause and CVD mortality. In addition, unpublished data from pooling projects were included. We pooled the multivariate-adjusted Hazards ratios (HRs) using random-effect meta-analysis, which allowed for between-study heterogeneity. Results: 27 studies covering 37 prospective cohorts were identified; these included 274,565 individuals with dietary assessment (34,597 all-cause and 10,636 CVD deaths) and 54,794 individuals with biomarker measurements (6,767 all-cause and 5,311 CVD deaths). Comparing the highest category with the lowest, dietary LA intake was associated with a 14% lower risk of all-cause mortality (95% confidence interval [CI], 2%-25%, I 2 =71%) and a 20% lower risk of CVD mortality (95% CI, 13%-26%, I 2 =0). Baseline health status (i.e. general population, CVD/high risk for CVD, or cancer) might be a main source of heterogeneity for the association of dietary LA intake with all-cause mortality. As for biomarkers, 1 SD increment in LA was associated with a 9% lower risk of all-cause mortality (95% CI, 4%-14%, I 2 =61%) and a 10% lower risk of CVD mortality (95% CI, 5%-14%, I 2 =13%). Heterogeneity was presented across tissue types and between genders. Conclusions: In prospective cohort studies, LA intake, assessed by either dietary survey or biomarkers, was inversely associated with all-cause and CVD mortality in a dose-response manner. These data support the current recommendations on polyunsaturated fat intake for prevention of CVD and early death.

Abstract Background This meta-analysis based on prospective cohort studies aimed to evaluate the associations of lipid profiles with the risk of major adverse cardiovascular outcomes in patients with coronary heart disease (CHD). Methods The PubMed, Embase, and Cochrane Library electronic databases were systematically searched for prospective cohort study published through December 2019, and the pooled results were calculated using the random-effects model. Results Twenty-one studies with a total of 76,221 patients with CHD met the inclusion criteria. The per standard deviation (SD) increase in triglyceride was associated with a reduced risk of major adverse cardiovascular events (MACE). Furthermore, the per SD increase in high-density lipoprotein cholesterol (HDL-C) was associated with a reduced risk of cardiac death, whereas patients with lower HDL-C were associated with an increased risk of MACE, all-cause mortality, and cardiac death. Finally, the risk of MACE was significantly increased in patients with CHD with high lipoprotein(a) levels. Conclusions The results of this study suggested that lipid profile variables could predict major cardiovascular outcomes and all-cause mortality in patients with CHD.

ObjectiveTo explore whether physical activity is inversely associated with the onset of depression, we quantified the cumulative association of customary physical activity with incident depression and with an increase in subclinical depressive symptoms over time as reported from prospective observational studies.DesignSystematic review and meta-analysis.Data sourcesMEDLINE, PsycINFO, PsycARTICLES and CINAHL Complete databases, supplemented by Google Scholar.Eligibility criteriaProspective cohort studies in adults, published prior to January 2020, reporting associations between physical activity and depression.Study appraisal and synthesisMultilevel random-effects meta-analysis was performed adjusting for study and cohort or region. Mixed-model meta-regression of putative modifiers.ResultsSearches yielded 111 reports including over 3 million adults sampled from 11 nations in five continents. Odds of incident cases of depression or an increase in subclinical depressive symptoms were reduced after exposure to physical activity (OR, 95% CI) in crude (0.69, 0.63 to 0.75; I2=93.7) and adjusted (0.79, 0.75 to 0.82; I2=87.6) analyses. Results were materially the same for incident depression and subclinical symptoms. Odds were lower after moderate or vigorous physical activity that met public health guidelines than after light physical activity. These odds were also lower when exposure to physical activity increased over time during a study period compared with the odds when physical activity was captured as a single baseline measure of exposure.ConclusionCustomary and increasing levels of moderate-to-vigorous physical activity in observational studies are inversely associated with incident depression and the onset of subclinical depressive symptoms among adults regardless of global region, gender, age or follow-up period.
