    Abstract: To assess the prospective associations of circulating levels of omega 3 polyunsaturated fatty acid (n-3 PUFA) biomarkers (including plant derived α linolenic acid and seafood derived eicosapentaenoic acid, docosapentaenoic acid, and docosahexaenoic acid) with incident chronic kidney disease (CKD). Design Pooled analysis. Data sources A consortium of 19 studies from 12 countries identified up to May 2020. Study selection Prospective studies with measured n-3 PUFA biomarker data and incident CKD based on estimated glomerular filtration rate. Data extraction and synthesis Each participating cohort conducted de novo analysis with prespecified and consistent exposures, outcomes, covariates, and models. The results were pooled across cohorts using inverse variance weighted meta-analysis. Main outcome measures Primary outcome of incident CKD was defined as new onset estimated glomerular filtration rate 〈 60 mL/min/1.73 m 2 . In a sensitivity analysis, incident CKD was defined as new onset estimated glomerular filtration rate 〈 60 mL/min/1.73 m 2 and 〈 75% of baseline rate. Results 25 570 participants were included in the primary outcome analysis and 4944 (19.3%) developed incident CKD during follow-up (weighted median 11.3 years). In multivariable adjusted models, higher levels of total seafood n-3 PUFAs were associated with a lower incident CKD risk (relative risk per interquintile range 0.92, 95% confidence interval 0.86 to 0.98; P=0.009, I 2 =9.9%). In categorical analyses, participants with total seafood n-3 PUFA level in the highest fifth had 13% lower risk of incident CKD compared with those in the lowest fifth (0.87, 0.80 to 0.96; P=0.005, I 2 =0.0%). Plant derived α linolenic acid levels were not associated with incident CKD (1.00, 0.94 to 1.06; P=0.94, I 2 =5.8%). Similar results were obtained in the sensitivity analysis. The association appeared consistent across subgroups by age (≥60 v 〈 60 years), estimated glomerular filtration rate (60-89 v ≥90 mL/min/1.73 m 2 ), hypertension, diabetes, and coronary heart disease at baseline. Conclusions Higher seafood derived n-3 PUFA levels were associated with lower risk of incident CKD, although this association was not found for plant derived n-3 PUFAs. These results support a favourable role for seafood derived n-3 PUFAs in preventing CKD.

    Abstract P212: Circulating And Tissue Omega-3 Fatty Acid Biomarkers And Incident Atrial Fibrillation: An Individual Participant-level Pooled Analysis Of Prospective Studies

    Abstract: Background: Evidence for the role of omega-3 fatty acids in the prevention of atrial fibrillation (AF) remain inconsistent, with some recent RCTs even suggesting possible harm. Whether long-term dietary intake of these fatty acids, as assessed using objective biomarkers, is related to AF is not known. Aims: To prospectively evaluate circulating and tissue levels of eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA), docosahexaenoic acid (DHA), and the sum of EPA and DHA (also known as the omega-3 index), with respect to incident AF. Methods: We used data from a global consortium of 13 prospective cohort studies with measurements of EPA, DPA, or DHA in adults (age≥18) identified through March 2021. Participating studies conducted de novo participant-level analyses using a prespecified analytical plan with harmonized definitions for exposures, outcomes, covariates, and subgroups. Associations were pooled using inverse-variance weighted meta-analysis. Results: Among 45,910 participants, a total of 6,229 incident cases of AF were ascertained, with median follow-up ranging from 0.9 to 29.1 years. In the multivariable analysis, per interquintile range (difference between the 90 th and 10 th percentiles for each fatty acid), DPA, DHA, and EPA+DHA ( Figure 1 ) were associated with 11%, 13%, and 9% lower incidence of AF, respectively ( P 〈 0.01 for each). EPA levels were not associated with incident AF. Heterogeneity as measured using I 2 ranged from 0% for DPA to 56.7% for EPA+DHA. Associations were broadly consistent irrespective of baseline cardiovascular risk, global region, age, sex, or lipid fraction. Conclusion: Biomarkers of omega-3 fatty acids including DPA, DHA, and EPA+DHA demonstrated an inverse association with incident AF. In the absence of RCTs examining long-term dietary omega-3 intake and AF risk, our results do not suggest that higher levels of these fatty acids are associated with harm.
