Dietary Saturated Fatty Acid Intake and Early Age-Related Macular Degeneration in a Japanese Population.

ABSTRACT: Purpose:To assess the association of dietary saturated fatty acid (SFA) intake with the presence of early AMD in a Japanese population. Methods:The population-based Tsuruoka Metabolomics Cohort Study enrolled general population individuals aged 35 to 74 years from among participants in annual health check-up programs that included fundus photographs in Tsuruoka, Japan. A total of 4010 individuals participated in the baseline survey. After excluding nonresponders to a dietary survey and participants with suboptimal fundus image quality, 3988 participants (median age, 62.4 years) were included in this cross-sectional analysis. Dietary intake was assessed by a validated food frequency questionnaire. Fatty acids intake was adjusted for total energy intake by the residuals method. The association between fatty acid intake and presence of early AMD was assessed by logistic regression models. Results:Median daily SFA intake was 11.3 g (interquartile range, 9.6, 13.0 g). After adjustments for potential confounding factors, participants in the highest quartile of SFA intake were less likely to have early AMD, compared with the lowest quartile (odds ratio, 0.71; 95% confidence interval: 0.52-0.96). A significant trend for decreased risk of early AMD with increasing SFA intake was noted (P = 0.011). There was no significant association between poly-unsaturated fatty acid (PUFA) including n3-PUFA intake and early AMD. Conclusions:We found that increased SFA intake was associated with reduced risk of early AMD in a Japanese population with low SFA intake. Adequate fatty acid intake may be required to maintain retinal homeostasis and prevent AMD.

Project description:PurposeTo evaluate the associations between intakes of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and the intermediate and advanced stages of age-related macular degeneration (AMD).DesignProspective cohort study.ParticipantsWe followed 75 889 women from the Nurses' Health Study and 38 961 men from the Health Professionals Follow-Up Study who were at least 50 years old, from 1984 to 2012 and 1986 to 2010, respectively. Cohort participants are mostly white (≥95%).MethodsWe assessed dietary intake by a validated food frequency questionnaire (FFQ) at baseline and every 4 years. We calculated cumulative average intakes of EPA and DHA from FFQs and also computed predicted erythrocyte and plasma scores directly from food intake using regression models. Cox proportional hazards models were used to compute the associations with AMD outcomes.Main outcome measuresWe confirmed 1589 incident intermediate and 1356 advanced AMD cases (primarily neovascular AMD) with a visual acuity of 20/30 or worse, owing primarily to AMD, by medical record review.ResultsFor intermediate AMD, the pooled hazard ratio (HR) between the 2 cohorts for DHA comparing the extreme quintiles of intake was 0.78 (95% confidence interval [CI], 0.66-0.92; P trend, 0.008) and for EPA + DHA was 0.83 (95% CI, 0.71-0.98; P trend, 0.03). The pooled HR for fatty fish, comparing ≥5 servings per week to almost never, was 0.61 (95% CI, 0.46-0.81; P trend, <0.001). For advanced AMD, the pooled HR for DHA was 1.01 (95% CI, 0.84-1.21; P trend, 0.75) and for fatty fish was 0.80 (95% CI, 0.59-1.08; P trend, 0.11). Secondary analyses using predicted erythrocyte and plasma scores of EPA and DHA yielded slightly stronger inverse associations for intermediate AMD and similar results for advanced AMD.ConclusionsHigher intakes of EPA and DHA may prevent or delay the occurrence of visually significant intermediate AMD. However, the totality of current evidence for EPA and DHA and advanced AMD is discordant, though there was no association with advanced AMD in the present study.

Project description:Importance:Previous studies of the role of dietary and supplementary calcium in age-related macular degeneration (AMD) have produced mixed results, suggesting that supplementation and decreased dietary intake are both harmful. Objective:To evaluate the association of baseline dietary and supplementary calcium intake with progression of AMD. Design, Setting, and Participants:This study involved secondary analyses of participants enrolled in the Age-Related Eye Disease Study (AREDS). The AREDS study (1992-2001) enrolled patients from academic and community-based retinal practices in the United States. Men and women with varying severity of AMD were included. Data analysis for this article occurred from September 2015 to December 2018. Exposures:Baseline self-reported dietary or supplementary calcium intake. Main Outcomes and Measures:Development of late AMD, geographic atrophy (central or noncentral), or neovascular AMD detected on centrally graded baseline and annual fundus photographs. Results:A total of 4751 participants were included (mean [SD] age, 69.4 [5.1] years); 4543 (95.6%) were white, and 2655 (55.9%) were female. Compared with those who were in the lowest quintile, the participants in the highest quintile of dietary calcium intake had a lower risk of developing late AMD (hazard ratio [HR], 0.73 [95% CI, 0.59-0.90]), central geographic atrophy (HR, 0.64 [95% CI, 0.48-0.86]), and any geographic atrophy (HR, 0.80 [95% CI, 0.64-1.00]). The participants in the highest tertile of supplementary calcium intake had a lower risk of developing neovascular AMD (HR, 0.70 [95% CI, 0.50-0.97]) compared with those who did not take calcium supplements. When stratified by sex, women in the highest quintile of dietary calcium intake had a lower risk of developing late AMD (HR, 0.73 [95% CI, 0.56-0.97]) compared with those in the lowest quintile. Women in the highest tertile of calcium supplementation had a lower risk of progression to neovascular AMD (HR, 0.67 [95% CI, 0.48-0.94]) compared with those who did not take calcium supplements. Similar findings were found in men for dietary calcium. Too few men took calcium supplements to allow for analyses. Conclusions and Relevance:In this secondary analysis, higher levels of dietary and supplementary calcium intake were associated with lower incidence of progression to late AMD in AREDS participants. The results may be owing to uncontrolled confounding or chance and should be considered hypothesis development requiring additional study.

Project description:Loss of choriocapillaris (CC) in advanced age-related macular degeneration (AMD) is well documented but changes in early AMD have not been quantified. Postmortem eyes from donors with clinically documented early AMD were examined in choroidal whole mounts to determine the area, pattern, and severity of CC loss. Choroids from postmortem human eyes without AMD (n = 7; mean age = 86.1) and from eyes with a Grade 2 clinical classification of early AMD (n = 7; mean age = 87) were immunolabeled with Ulex europaeus agglutinin (UEA) lectin-FITC to stain blood vessels. Whole mounts were imaged using confocal microscopy and image analysis was performed to determine the area of vascular changes and density of vasculature (percent vascular area, %VA). All areas evaluated had a complete RPE monolayer upon gross examination. In age-matched control eyes, the CC had broad lumens and a homogenous pattern of freely interconnecting capillaries. The mean %VA ± standard deviation in submacula of control subjects was 78.1 ± 3.25%. In eyes with early AMD, there was a significant decrease in mean %VA to 60.1 ± 10.4% (p < 0.0001). The paramacular %VA was not significantly different in eyes with or without AMD. The area of submacular choroid affected by CC dropout was 0.04 ± 0.09 mm2 in control eyes. In eyes with early AMD, the mean area affected by CC dropout was significantly increased (10.4 ± 6.1 mm2; p < 0.001). In some cases, incipient neovascular buds were observed at the border of regions with CC dropout in early AMD choroids. In conclusion, UEA lectin-labeled choroidal whole mounts from donors with clinically documented early AMD has provided a unique opportunity to examine regional changes in vascular pathology associated with choriocapillaris. The study demonstrated attenuation of submacular CC in early AMD subjects but no vascular pathology was observed outside the submacular region. While the affected area in some eyes was quite extensive histologically, these changes may not be detectable clinically using standard in vivo imaging.
