Abstract
BACKGROUND/OBJECTIVES To assess the prevalence and correlates of impaired activities of daily living (ADLs) in patients with neovascular age-related macular degeneration (nAMD) who present for anti-vascular endothelial growth factor (VEGF) therapy. METHODS In a clinic-based cohort of 437 patients with nAMD who presented for anti-VEGF therapy, the Older American Resources and Services Scale (OARS) was administered to assess for impairments in basic, instrumental and total ADL. Logistic regression analyses were conducted to determine odds ratios (OR) and 95% confidence intervals (CI) for factors associated with ADL impairment. RESULTS The prevalence of impaired basic, instrumental and total ADL was 37.76%, 67.82% and 39.59%, respectively. In multivariate-adjusted models, moderate visual impairment [OR 5.65, 95% CI (2.31-13.83) and blindness [OR 5.43, 95% CI (2.09-14.12)] were associated with greater odds of impaired total ADL. Depressive symptoms [OR 2.08, 95% CI (1.08-4.00)], the presence of any disability [OR 3.16, 95% CI (1.64-0.07)] and never driving [OR 4.00, 95% CI (1.60-10.00)] were also positively associated with total ADL impairment. Better vision-related quality of life (QoL) was inversely associated with impaired instrumental ADL whilst higher health-related QoL scores were associated with decreased odds of total ADL impairment. CONCLUSIONS There is a high prevalence rate of ADL impairment among nAMD patients presenting for therapy. Visual impairment, never driving, poor physical and mental health increased the odds of experiencing ADL impairment whilst better VRQoL and HRQoL reduced the odds of impairment.

Abstract
OBJECTIVES We used a cohort of community-dwelling adults to establish the 10-year incidence and predictors of dizziness/vertigo, and its impacts on health-related quality of life. STUDY DESIGN Of the 1152 participants aged 55 + years who did not have dizziness/vertigo at baseline, 799 and 377 participants were followed up after 5 and 10 years, respectively, and had complete data and so were included in the incidence analysis. Hearing loss was determined as the pure-tone average of audiometric hearing thresholds at 500, 1000, 2000 and 4000 Hz, and any hearing loss was defined as >25 dB hearing level. Tinnitus and migraine were assessed by a positive response to a single question. MAIN OUTCOME MEASURES Audiologists screened participants for reported dizziness using a single question. Quality of life was measured using the Short Form 36-item Health Survey (SF-36). RESULTS The cumulative 10-year incidence of dizziness/vertigo, vestibular vertigo and non-vestibular vertigo were 39.8 %, 27.1 %, and 11.9 %, respectively. Age and presence of migraine were significant predictors of incident dizziness/vertigo: multivariable-adjusted hazard ratio (HR) 1.03 (95 % confidence interval, CI, 1.01-1.06) and HR 1.63 (95 % CI 1.13-2.35), respectively. A significant decrease in scores for the following SF-36 domains was observed over the 10 years among participants reporting baseline dizziness/vertigo: physical functioning (P-trend ≤ 0.0001), role limitation due to physical problems (P-trend ≤ 0.0001), general health (P-trend = 0.01), and vitality (P-trend = 0.01). CONCLUSIONS Dizziness/vertigo was a frequent and detrimental symptom in this population of community-dwelling adults. Our study highlights the burden imposed by dizziness, as evidenced by a significant prospective association with poorer quality of life.

Abstract
BACKGROUND/OBJECTIVES To examine the risk factors for poor vision-related and health-related quality of life (QoL) in patients with neovascular age-related macular degeneration (nAMD) who present for anti-vascular endothelial growth factor (anti-VEGF) therapy. METHODS In a clinic-based cohort of 547 nAMD patients who presented for treatment, the National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ25), Short-Form 36 (SF-36) and EuroQoL EQ-5D-5L questionnaires were administered to assess vision-related and health-related QoL. Of these, 83 participants were followed up one-year later to provide longitudinal data. RESULTS Individuals with mild or moderate visual impairment or blindness at baseline had significantly lower NEI-VFQ-25 scores at follow-up. The presence of ≥3 chronic diseases was associated with lower SF-36 mental component scores (MCS) (p = 0.04) and EQ-VAS scores (p = 0.05). Depressive symptoms were associated with significantly lower MCS (p < 0.0001) and EQ-VAS scores (p = 0.02). Individuals with versus without impaired basic activities of daily living (ADLs) exhibited NEI-VFQ-25 and EQ-VAS scores that were 10.96 (p = 0.03) and 0.13 (p = 0.02) points lower. Those with impaired instrumental ADLs scored 11.62 (p = 0.02), 13.13 (p < 0.0001) and 15.8 (p = 0.0012) points lower in the NEI-VFQ-25, SF-36 physical component score and EQ-5D-5L summary score, respectively. CONCLUSIONS The QoL of nAMD patients is affected by visual acuity as well as patients' medical history, mental health and functional status.

Abstract
BACKGROUND AND AIMS To report on the relationship between dietary intakes of a broad range of macronutrients and micronutrients, including antioxidants and fatty acids, with the presence of dry eye symptoms. METHODS Population-based cross-sectional study of 1952 urban Sydney residents aged 60 years or greater. Participants completed a validated semi-quantitative 145-item food frequency questionnaire and a dry eye questionnaire. RESULTS A total of 1528 responses were recorded (78.3%) of which 902 (59.0%) were female. 53.8% of participants reported at least one dry eye symptom, more commonly by women (58.2%) compared to men (47.3%). Participants in the highest (8.11 mcg/day) versus lowest quartile of intake of dietary B12 had reduced likelihood of reporting more than 2 dry eye symptoms and 1 or more moderate-severe dry eye symptoms: OR 0.64 (95% CI: 0.41-1.00) and OR 0.63 (95% CI: 0.41-0.97), respectively. Higher dietary intakes of vitamin C, thiamine (vitamin B1), polyunsaturated fats and calcium, were all associated with a reduced likelihood of participants reporting more than 2 dry eye symptoms (p < 0.05 for all). CONCLUSIONS Intakes of a broad range of micro- and macro-nutrients were significantly and independently associated with reduced odds of experiencing dry eye symptoms. These data suggest that clinicians may need to consider current diet in patients presenting with dry eye symptoms.

Abstract
OBJECTIVES We aimed to assess whether objectively measured hearing loss and self-perceived hearing handicap in adults are independently associated with food insecurity, and vice versa. DESIGN Cross-sectional population-based study. POPULATION 2,500 participants aged 50+ years from the Blue Mountains Hearing Study, with both complete pure-tone audiometry data and information on food security status. MEASUREMENTS The pure-tone average of frequencies 0.5, 1.0, 2.0 and 4.0 kHz (PTA0.5-4KHz) >25 dB HL in the better ear, established the presence of hearing loss. Self-perceived hearing handicap was assessed by administering the Hearing Handicap Inventory for Elderly Screening (HHIE-S total scores of ≥8 indicates hearing handicap). A 12-item food security survey was administered, comprising statements related to individual and household food situations. RESULTS Food insecurity was reported by 12.8% of study participants. After adjusting for all potential confounders, any self-perceived hearing handicap significantly increased the likelihood of participants reporting food insecurity by 94% (p<0.0001). Participants reporting any, mild or severe self-perceived hearing handicap had around 2-fold greater odds of experiencing food insecurity. Objectively measured hearing loss did not significantly influence the food security status of study participants. Conversely, food insecurity was significantly associated with both objectively measured hearing loss and self-perceived hearing handicap: multivariate-adjusted OR 1.37 (95% CI 1.01-1.88) and OR 1.83 (95% CI 1.40-2.39), respectively. CONCLUSIONS Food insecurity was an important social determinant of hearing health among community-dwelling adults. Conversely, participants with a significant self-perceived hearing handicap were more likely to experience food insecurity. These findings add to our understanding of the substantial public health impact of both food insecurity and hearing loss and may highlight areas for future intervention.

Abstract
Tinnitus is the phantom perception of sound in the ears or head that increases in prevalence as age increases. With strong evidence supporting the benefits of dietary fibre for vascular health and hearing loss, intake of dietary fibre may also have a role in the prevention of tinnitus symptoms. This longitudinal study aims to determine the association between the intake of dietary fibre and other carbohydrate nutrition variables including glycaemic index (GI), glycaemic load (GL) and total carbohydrate intakes, and incident tinnitus over 10 years. Of the 1730 participants (aged ≥50 years) from the Blue Mountains Hearing Study with complete baseline data on tinnitus symptoms and carbohydrate intakes, 536 (31%) cases of tinnitus were identified and excluded from further incidence analysis. Dietary data were collected using a validated semi-quantitative food frequency questionnaire to determine intakes of total dietary fibre and fibre contributions from cereals, vegetables, and fruit. A purpose-built database based on Australian GI values was used to calculate mean GI. Lower versus higher intakes of fruit fibre (≤3.6 g/day vs. >3.6 g/day) and cereal fibre (≤4.2 g/day vs. >4.2 g/day) were significantly associated with a 65% (HR = 1.65; 95% CI: 1.15–2.36) and 54% (HR = 1.54; 95% CI: 1.07–2.22) increased risk of developing tinnitus over 10 years, respectively. Associations between intake of other carbohydrate nutrients and incident tinnitus were mostly non-significant. In summary, our study showed modest associations between intake of dietary fibre and incident tinnitus. The protective effects of fibre, particularly insoluble fibre, could underlie observed associations by reducing the risk of tinnitus via vascular risk factors such as cardiovascular disease. Further longitudinal studies evaluating different types and sources of fibre and tinnitus risk are needed to confirm our study findings.

Abstract
OBJECTIVES We aimed to analyse the degree of carer burden and depressive symptoms in family carers of persons with age-related macular degeneration (AMD) and explore the factors independently associated with carer burden and depressive symptoms. METHODS Cross-sectional study using self-administered and interviewer-administered surveys, involving 96 family carer-care recipient pairs. Participants were identified from tertiary ophthalmology clinics in Sydney, Australia, as well as the Macular Disease Foundation of Australia database. Logistic regression, Pearson and Spearman correlation analyses were used to investigate associations of explanatory factors (family caregiving experience, carer fatigue, carer quality of life and care-recipient level of dependency) with study outcomes-carer burden and depressive symptoms. RESULTS Over one in two family carers reported experiencing mild or moderate-severe burden. More than one in five and more than one in three family carers experienced depressive symptoms and substantial fatigue, respectively. High level of care-recipient dependency was associated with greater odds of moderate-severe and mild carer burden, multivariable-adjusted OR 8.42 (95% CI 1.88 to 37.60) and OR 4.26 (95% CI 1.35 to 13.43), respectively. High levels of fatigue were associated with threefold greater odds of the carer experiencing depressive symptoms, multivariable-adjusted OR 3.47 (95% CI 1.00 to 12.05). CONCLUSIONS A substantial degree of morbidity is observed in family carers during the caregiving experience for patients with AMD. Level of dependency on the family carer and fatigue were independently associated with family carer burden and depressive symptoms. TRIAL REGISTRATION NUMBER The trial registration number is ACTRN12616001461482. The results presented in this paper are Pre-results stage.

Abstract
BACKGROUND We piloted an educational intervention that aimed to enhance awareness about nutrition-age-related macular degeneration (AMD) links among practising and student dietitians then expanded the scope of this intervention to include general eye health, which was delivered to pharmacy students. METHODS A pilot intervention was conducted in 2019 at the Dietitians Australia Conference (Gold Coast, Australia) where practising and student dietitians underwent a 2-hour small group educational workshop on nutrition and AMD links. Pre-post questionnaires were administered to participants, with voluntary completion of both questionnaires an indicator of consent to participate in the intervention. The primary intervention outcome was a change in AMD-related nutrition knowledge pre-post intervention. A larger intervention was then conducted at the University of Sydney (Sydney, Australia) where pharmacy students underwent a 4-hour educational module to improve general eye health knowledge, as well as student perceptions and attitudes towards a pharmacists' role in low vision care. Similarly, pre-post questionnaires were administered, with voluntary completion of both questionnaires an indicator of consent to participate in the intervention. The primary intervention outcomes were changes in total knowledge, total perception and total attitude scores pre-post intervention. RESULTS (1) Among 10 accredited and 5 student dietitians, there was significant overall knowledge improvement (mean pre-post score: 7.07 ± 1.94 vs. 10.8 ± 1.01, p = 0.001) specifically around appropriate dietary advice, food sources of key AMD-related nutrients, and awareness of supplements. (2) Among 179 second-year pharmacy students enrolled in the 'Pharmacy Practice' Unit of Study (Bachelor of Pharmacy, University of Sydney), total eye health knowledge (6.25 ± 1.93 vs. 6.64 ± 2.0; p = 0.011) significantly improved, along with total perception scores (41.54 ± 5.26 vs. 42.45 ± 4.95; p = 0.004). Total attitude scores were not significantly different. CONCLUSIONS The pilot intervention improved relevant nutrition-AMD knowledge among practising/student dietitians. The modified intervention for pharmacy students also significantly improved general eye health knowledge as well as students' perception of a pharmacists' role in low vision care.

Abstract
There is paucity of population-based data on occupational noise exposure and risk of age-related hearing loss. Therefore, we assessed cross-sectional and longitudinal associations of past workplace noise exposure with hearing loss in older adults. At baseline, 1923 participants aged 50+ years with audiological and occupational noise exposure data included for analysis. The pure-tone average of frequencies 0.5, 1.0, 2.0 and 4.0 kHz (PTA0.5-4KHz) >25 dB HL in the better ear, established the presence of hearing loss. Participants reported exposure to workplace noise, and the severity and duration of this exposure. Prior occupational noise exposure was associated with a 2-fold increased odds of moderate-to-severe hearing loss: multivariable-adjusted OR 2.35 (95% CI 1.45–3.79). Exposure to workplace noise for >10 years increased the odds of having any hearing loss (OR 2.39, 95% CI 1.37–4.19) and moderate-to-severe hearing loss (OR 6.80, 95% CI 2.97–15.60). Among participants reporting past workplace noise exposure at baseline the 10-year incidence of hearing loss was 35.5% versus 29.1% in those who had no workplace noise exposure. Workplace noise exposure was associated with a greater risk of incident hearing loss during the 10-year follow-up: multivariable-adjusted OR 1.39 (95% CI 1.13–1.71). Prior occupational noise exposure was not associated with hearing loss progression. Workplace noise exposure increased the risk of incident hearing loss in older adults. Our findings underscore the importance of preventive measures which diminish noise exposure in the workplace, which could potentially contribute towards reducing the burden of hearing loss in later life.

Abstract
Purpose To describe the prevalence, risk factors, and associations of vitreoretinal interface (VRI) abnormalities in a population-based study of older adults. Design Cross-sectional analysis of cohort study participants. Participants Of the 1149 participants (mean age, 76.1 ± 6.9 years) in the 15-year Blue Mountains Eye Study follow-up examination from 2007 through 2009, 905 (1791 eyes) had gradable time-domain or spectral-domain OCT scans of the macula from at least 1 eye. Methods OCT scans were graded according to the International Vitreomacular Traction Study Group classification system of VRI abnormalities. Best-corrected visual acuity (BCVA) was recorded. Main Outcome Measures Prevalence of VRIs. Results Overall, 451 participants showed any VRI abnormality (49.8%). Prevalence of VRI abnormality by person was: vitreomacular adhesion (VMA), 33.6%; vitreomacular traction (VMT), 1.6%; epiretinal membrane (ERM), 21.4%; full-thickness macular hole (FTMH), 0.7%; and lamellar macular hole (LMH), 0.7%. Twenty-two percent of VMAs were focal, and 78% were broad based; 76% of VMTs were focal, and 24% were broad based. All FTMHs observed were large (>400 μm), with mean aperture size of 573 μm (range, 459–771 μm). Increased age was associated with higher ERM and lower VMA prevalence (P < 0.001 for both). Pseudophakia and myopia were associated with ERM (age- and sex-adjusted odds ratios [ORs], 1.48 [95% confidence interval (CI), 1.01–2.17] and 1.72 [95% CI, 1.05–2.81], respectively). Moderate or severe ERM and FTMH were associated with worse BCVA of 9.2 Early Treatment Diabetic Retinopathy Study (ETDRS) letters (95% CI, 3.4–15.0 ETDRS letters; P = 0.008) and 26.0 ETDRS letters (95% CI, 10.9–41.1 ETDRS letters; P = 0.001), respectively. Conclusions The prevalence of VRI abnormalities is high in older individuals. Epiretinal membrane was associated with increasing age, pseudophakia, and myopia. Epiretinal membrane and FTMH may account for significant visual loss in the affected eye. This study provided useful population-based data on the prevalence of VRI abnormalities in older individuals.

Abstract
PURPOSE To examine the prevalence and risk factors for depressive symptoms in patients with neovascular age-related macular degeneration (nAMD) presenting for anti-vascular endothelial growth factor (anti-VEGF) therapy. METHODS In a clinic-based cohort of 547 patients with nAMD who presented for treatment, the Centre of Epidemiological Studies Depression 10-point scale (CES-D-10) and Mental Health Index (MHI) component of the 36-item Short Form Survey were administered to assess for the presence of depressive symptoms. Logistic regression analyses were used to calculate odds ratios and 95% confidence intervals for factors associated with an increased likelihood of depressive symptoms. RESULTS The prevalence of depressive symptoms was 42.04% and 31.78% as per the CES-D-10 and MHI scales, respectively. Poor self-rated health (SRH) is associated with increased odds of depressive symptoms [multivariable-adjusted OR: 3.00 (95% CI 1.90-4.73) for CES-D-10; OR: 2.67 (95% CI 1.67-4.28) for MHI]. Impaired activities of daily living (ADLs) [multivariable-adjusted OR: 2.62 (95% CI 1.56-4.38) for CES-D-10; OR: 3.59 (95% CI 2.10-6.15) for MHI] and a visual function score within the two lowest quartiles were also associated with increased odds of depressive symptoms using both scales. CONCLUSION A high prevalence of depressive symptoms was observed among nAMD patients presenting for treatment. Poorer SRH, ADL impairment and reduced visual function were associated with increased odds of depressive symptoms.

Abstract
BACKGROUND AND PURPOSE Fractal analysis is a method of quantifying the branching complexity and density of the retinal vessels. We hypothesized that reduced fractal dimension, signifying a sparser vascular network, is associated with long-term stroke mortality. METHODS We examined the relationship of fractal dimension and stroke mortality in a prospective, population-based cohort of 3143 participants aged 49 years or older. Fractal dimension was measured from digitized fundus photographs using a computer-automated method. Stroke mortality was documented from Australian National Death Index records. We defined reduced fractal dimension as values in the lowest quartile. RESULTS Over 12 years, there were 132 (4.2%) stroke-related deaths. Stroke-related mortality was higher in participants with reduced fractal dimension (lowest quartile) compared with the highest quartile (7.7% versus 1.3%, P<0.01). After controlling for age, gender, smoking, blood pressure, history of stroke, and other factors, participants with reduced fractal dimension had higher stroke mortality (hazard ratio, 2.42 [95% CI, 1.15-5.07], lowest versus highest quartile). When modeled as a continuous variable, reduced fractal dimension was associated with increased stroke mortality (multivariable-adjusted hazard ratio, 1.26 [95% CI, 1.06-1.51], per SD decrease). CONCLUSIONS Reduced retinal vascular fractal dimension is independently associated with 12-year stroke mortality. Reduced fractal dimension may indicate cerebral tissue hypoxia and increased risk of stroke.

Abstract
OBJECTIVE We aimed to prospectively examine the relationship between vision and hearing loss and successful aging in a cohort of older adults. STUDY DESIGN We analyzed 5-year data (1997-9 to 2002-4) from 1,085 adults aged 55+ years, who were free of cancer, coronary artery disease and stroke at baseline and who had complete data on sensory loss. MAIN OUTCOME MEASURES Visual impairment was defined as visual acuity <20/40 (better eye), and hearing impairment as average pure-tone air conduction threshold >25 dBHL (500-4000 Hz, better ear). Successful aging was defined as the absence of: disability, depressive symptoms, cognitive impairment, respiratory symptoms and chronic diseases (cancer, coronary artery disease and stroke) at 5-year follow-up. RESULTS At 5-year follow-up, 243 (22.4%) participants had died and 248 (22.9%) had aged successfully. After multivariable adjustment, participants who had either best-corrected visual impairment or bilateral hearing impairment, versus those who did not have sensory impairment at baseline, had 37% reduced odds of successful aging after 5 years: OR 0.63 (95% CI 0.43-0.94). Concurrent vision and hearing loss at baseline was not associated with 5-year aging status. Participants with moderate and severe hearing handicap at baseline had 50% and 61% reduced odds of aging successfully after 5 years, respectively. CONCLUSION The presence of a single sensory impairment in older adults was associated with reduced odds of being disease-free and fully functional or having aged successfully, 5 years later. Objectively measured hearing loss and self-perceived hearing handicap, rather than vision loss, was more likely to negatively influence 5-year aging status.

Abstract
PURPOSE To assess whether dietary intake of antioxidants, fruits, vegetables and fish is associated with 12-month treatment outcomes in neovascular age-related macular degeneration (nAMD) patients. METHODS A total of 547 participants were diagnosed with nAMD at baseline, of whom 494 were followed up after 12 months of antivascular endothelial growth factor therapy. Dietary intakes were determined using a validated food frequency questionnaire. Presence of intra-retinal and sub-retinal fluid (IRF, SRF), pigment epithelial detachment (PED) and central macular thickness (CMT) were recorded from optical coherence tomography images. Best-corrected visual acuity was recorded using log of the Minimum Angle of Resolution (LogMAR) charts. RESULTS Participants in the upper three quartiles combined compared to those in the first quartile of baseline dietary zinc intake had 49% reduced odds of SRF 12 months later, multivariable-adjusted odds ratio (OR) 0.51 [95% confidence interval (CI) 0.30-0.89]. The upper three quartiles combined compared to the first quartile of β-carotene intake had 90% greater odds of IRF presence at 12-month follow-up, multivariable-adjusted OR 1.90 (95% CI 1.04-3.46). The highest versus lowest quartile of dietary β-carotene intake had a nearly twofold greater odds of PED presence, multivariable-adjusted OR 1.99 (95% CI 1.03-3.84). CONCLUSION A higher intake of dietary zinc was associated with a reduced likelihood of SRF at 1 year. Conversely, a higher intake of dietary β-carotene was associated with an increased risk of IRF and PED. These findings underscore the importance of ongoing nutritional advice for nAMD patients presenting for treatment.

Abstract
There is an evidence-practice gap between the dietary recommendations for age-related macular degeneration (AMD) presented in the literature and those practiced by patients. This study reports on the 3-month post-intervention results of a randomised controlled trial (RCT) evaluating telephone-delivered counselling to improve dietary behaviours among AMD patients. A total of 155 AMD patients (57% female, aged 78 ± 8 years; control: 78, intervention: 77), primarily residing in New South Wales, Australia, were recruited. Participants completed a baseline questionnaire and a short dietary questionnaire (SDQ-AMD). The intervention included an evidence-based nutrition resource and four monthly calls with a dietitian. Immediately post-intervention, intervention participants repeated the SDQ-AMD and completed a feedback form. At 3 months post-intervention, both study arms repeated the SDQ-AMD. Statistical analyses included t-tests and McNemar's test. Intervention participants reported satisfaction with the tailored phone calls, nutrition resource and nutrition education provided. At 3 months post-intervention, there was no statistically significant difference between study arms in the proportion of participants meeting the dietary goals nor in intake (mean servings ± SE) of total vegetables (primary outcome) and other key food groups; however, there was a significantly higher intake of nuts (secondary outcome) (3.96 ± 0.51 vs. 2.71 ± 0.32; p = 0.04) among participants in the intervention versus control group. Within the intervention arm, there were also significant improvements in intakes of the following secondary outcomes: dark green leafy vegetables (0.99 ± 0.17 vs. 1.71 ± 0.22; p = 0.003) and legumes (0.69 ± 0.10 vs. 1.12 ± 0.16; p = 0.02) and intake of sweets and processed/prepared foods (8.31 ± 0.76 vs. 6.54 ± 0.58, p = 0.01). In summary, although there were few dietary differences between study arms at 3 months post-intervention, the intervention involving four monthly calls was acceptable and helpful to the participants. This type of intervention therefore has the potential to provide people with AMD the needed support for improving their nutrition knowledge and dietary practices, especially if continued over a longer period.

Abstract
BACKGROUND To assess the association of smoking with age of onset of neovascular age-related macular degeneration (nAMD), visual acuity (VA), central macular thickness (CMT) and the presence of fluid in patients with nAMD. METHODS 547 patients with nAMD were recruited from a tertiary eye clinic during 2012-2015; of these, 490 patients were followed up 12 months later. Clinical diagnosis of nAMD was confirmed by a retinal specialist. Smoking was determined from self-reported history as never, past or current. Age of onset was defined as date of first recorded diagnosis of nAMD in either eye or date of first anti-vascular endothelial growth factor injection. CMT and presence of fluid were recorded from spectral-domain optical coherence tomography images. VA was recorded as number of letters read at 3 m. RESULTS After multivariable adjustment, current smokers developed nAMD at an average 5.5 years younger age than never smokers and 4.4 years younger age than past smokers (p<0.0001 and p=0.0008, respectively). At baseline, adjusted mean CMT was significantly higher in current compared with past smokers (259.2 µm vs 231.9 µm, respectively, p=0.04). Current smokers versus never smokers had greater odds of presence of subretinal fluid at 12-month follow-up: multivariable-adjusted OR 1.99 (95% CI 1.09 to 3.67). Smoking status was not significantly associated with VA over 12 months. CONCLUSIONS Current smoking was associated with a younger age of nAMD onset and key treatment outcomes such as higher mean CMT and greater odds of subretinal fluid presence. These findings suggest that smoking cessation may benefit patients being treated for nAMD.

Abstract
BACKGROUND Greater adherence to dietary guidelines has previously been found to be associated with decreased risk of visual impairment. However, whether or not this association extends to age-related cataract, 1 of the leading causes of visual impairment, is unknown. OBJECTIVES The aim of this study was to assess the association between adherence to dietary guidelines, using total diet score, and incidence of age-related cataract. METHODS Of 3654 baseline participants of the population-based Blue Mountains Eye Study cohort (1992-1994), 2334 (75.8% survivors) and 1952 (76.7% survivors) were examined after 5 and 10 y, respectively. Cataract was assessed from lens photographs using the Wisconsin Cataract Grading System. Baseline total diet score was calculated from FFQ data following a modified version of the Healthy Eating Index for Australians. OR with 95% CI were estimated using discrete logistic regression analyses, adjusting for age, sex, and other confounders. To test interaction, a cross-product term of 2 factors was included in regression models. RESULTS Of 2173 participants (84.7% of those returned for 1 or both follow-ups) with total diet score estimated, 57% were women, mean baseline age was 63.9 ± 8.4y, and mean baseline BMI was 26.3 ± 4.3 kg/m2. After multivariable adjustment, baseline total diet score was not associated with incidence of any cataract. A multiplicative interaction was observed between total diet score and BMI for incident nuclear cataract (P-interaction = 0.04): increasing baseline total diet score was associated with decreased risk of nuclear cataract among participants with BMI <25 (per unit increased total diet score, OR: 0.90; 95% CI: 0.81, 0.99; P = 0.02), but not among participants with BMI ≥25 (OR: 1.00; 95% CI: 0.92, 1.10; P = 0.95). CONCLUSIONS Adherence to dietary guidelines had no appreciable influence on cataract development overall in this older Australian population. However, adherence to dietary guidelines combined with healthy BMI is associated with decreased risk of nuclear cataract, an aging marker.

Abstract
Objectives: We aimed to assess the cross-sectional associations between sensory impairments (vision, hearing, and/or olfactory loss) and handgrip strength. Method: In the Blue Mountains Eye Study, 947 participants aged 65+ years had handgrip strength measured using a dynamometer. Visual impairment was defined as visual acuity <20/40 (better eye), and hearing impairment as average pure-tone air conduction threshold >25 dBHL (500-4,000 Hz). Olfaction was measured using the San Diego Odor Identification Test. Results: Marginally significant associations between sensory impairment and handgrip strength were observed after multivariable adjustment. For example, women with two or three sensory impairments had lower adjusted mean handgrip strength (17.47 ± 0.5 kg) versus women who had no sensory loss (18.59 ± 0.3 kg; p = .06) or only one sensory impairment (18.58 ± 0.3 kg; p = .05), respectively. No significant associations were observed in men. Discussion: Women who had multiple sensory impairments had reduced muscle strength as indicated by ~1.1 kg lower mean handgrip strength.

Abstract
OBJECTIVE Microvascular changes in microvascular angina are poorly understood due to difficulties in imaging the coronary microcirculation in vivo. The retinal microvasculature may reflect changes in coronary microcirculation. We assessed microvascular changes in the retina in patients with microvascular angina and compared them with patients with angiographically proven coronary artery disease. METHODS We performed retinal photography and coronary angiography on 915 patients. Retinal vessel calibers were measured using a validated computer-assisted method; coronary artery disease was graded from coronary angiograms. Microvascular angina was defined as angina with <25% stenosis in all coronary epicardial arteries. RESULTS A total of 139 patients (15.2%) had microvascular angina, while 776 (84.8%) had coronary artery disease. Participants with microvascular angina and coronary artery disease had similar retinal arteriolar and venular calibers. After adjustment for age, ethnicity, mean arterial pressure, diabetes, current smoking, body mass index, and fellow vessel caliber, women with smaller venules were threefold more likely to have microvascular angina than women with larger venules (multivariable-adjusted odds ratio 3.54, 95% confidence interval 1.35 to 9.24, P < 0.01). This difference was not observed in men. CONCLUSIONS Microvascular angina in women was associated with microvascular changes distinct from those in coronary artery disease.

Abstract
Background This study aims to explore retinal vessel calibre in individuals at risk of coronary artery disease (CAD), diagnosed with impaired fasting glucose (IFG) or diabetes mellitus (DM), and whether indices of CAD extent and severity modifies these associations with DM. Methods A cross-sectional study was undertaken of 1680 patients presenting to Westmead Hospital (Sydney, Australia) for evaluation of potential CAD. Baseline digital retinal photographs, cardiovascular risk factor measurements, fasting blood tests and self-reported diabetes by patient questionnaire was recorded. Extent and severity of CAD was assessed using Extent and Gensini scores from angiography findings, respectively. Multivariate analysis including age and hypertension was undertaken to assess the association between retinal vessel calibre and IFG or DM. Results A total of 748 patients were included; 96 (12.8%) and 189 (25.3%), respectively, had IFG or DM (together termed ‘hyperglycaemia’). No consistent association between hyperglycaemia and retinal arteriolar calibre was apparent. Wider retinal venular calibre (second and third tertile) carried a significantly higher odds of DM in men only (multivariable-adjusted OR 2.447, p = 0.005; and OR 2.76, p = 0.002; respectively). No equivalent association was apparent in women. This association was marginally significant (p = 0.08) in patients with CAD Extent scores below the median (i.e. less diffuse CAD). Retinal vessel calibre was not associated with impaired fasting glucose. Conclusions This study reports a significant association between retinal venular widening and diabetes mellitus in men. This association was marginally stronger among participants with less diffuse CAD.

Abstract
BACKGROUND AND AIMS We aimed to comprehensively describe a spectrum of retinal vessel measures including fractal dimension (Df) and their associations with indices of coronary artery disease (CAD) extent and severity, as well as hypertension and diabetes. METHODS The Australian Heart Eye Study (AHES) is an observational study that surveyed 1680 participants presenting to a tertiary referral hospital for the evaluation of potential CAD by coronary angiography. A range of newer retinal vessel geometric measures (Df, curvature tortuosity, and branching angle) were quantified from retinal photographs using semi-automated software, the Singapore 'I' Vessel Assessment (SIVA) tool. A combined retinal score was constructed, aiming to assess the joint effect of multiple retinal vessel parameters on CAD, comprising of those variables that were most strongly significant in multivariate analysis - Df, arteriolar curvature tortuosity, and retinal arteriolar calibre. CAD was objectively quantified using a range of measures obtained from coronary angiography. RESULTS A total of 1187 participants had complete data on retinal vessel measurements and coronary vessel evaluation. Retinal vascular Df and curvature tortuosity decreased with increasing age; women had significantly lower Df than men (p<0.003). Straighter retinal vessels were associated with CAD extent and Gensini scores in multivariable analysis (p<0.02). Accounting for media opacity by sub-group analysis in pseudophakic patients, the combined retinal score was associated with stenosis greater than 50% in any coronary artery segment (vessel score) and obstructive coronary stenosis in all three main coronary arteries (segment score) (p = 0.01). Lower Df and narrower arteriolar branching angle were associated with CAD vessel score (p<0.03). In sex-stratified multivariate analyses, straighter arterioles were associated with greater odds of CAD in men, and narrower venular branching angle was associated with CAD in women. CONCLUSIONS A range of retinal vessel measures were associated with CAD extent and severity. A sparser retinal microvascular network (smaller Df) was associated with older age and female gender. After accounting for the impact of media opacity, retinal vessel measures were associated with more diffuse and severe CAD.

Abstract
Background Little is known about the significance of severe coronary tortuosity (SCT) despite it being a relatively common finding on coronary angiography. We examined whether the presence of tortuosity was influenced by gender or cardiac risk factors. Methods and results We examined 870 patients (Men = 589, Women = 281) who presented to Westmead Hospital, Sydney, Australia for invasive coronary angiography for the assessment of chest pain due to suspected CAD. Female gender and age were significantly associated with SCT (p < 0.001 for age) with 45.2% of women having SCT as opposed to 19.7% of men (p < 0.001). Men with SCT had lower Extent scores only compared than those without tortuosity (22.4 vs. 32.4, p = 0.003). However, women with SCT had less severe coronary artery disease than those with no SCT as measured by both the Extent score (12.4 vs. 19.1, p = 0.03) and Gensini score (10.4 vs. 15.5, p = 0.02). Conclusion There is a significant relationship between coronary artery tortuosity and gender. Women with severe tortuosity are more likely to have normal coronary arteries or less severe disease than men despite presenting with chest pain.

Abstract
We aimed to investigate whether fish and long chain omega-3 polyunsaturated fatty acid (LCn-3 PUFA) consumption changed appreciably during adolescence. We also assessed whether these dietary variables are associated with retinal microvascular signs (possible markers of future cardiovascular disease risk). 633 children had dietary data at ages 12 and 17. Fish and LCn-3 PUFA [eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA) and docosahexaenoic acid (DHA)] intake was assessed by a food frequency questionnaire. Retinal vessel caliber was quantified from digital photographs using computer software. Mean energy-adjusted intakes (mg/day) of total LCn-3 PUFA, EPA, and DHA at age 12 were 297.1±261.1; 102.5±106.9; and 129.7±137.7, respectively; and this increased significantly at age 17 to: 347.0±324.0 (p<0.0001); 122.5±132.7 (p = 0.0001); and 160.3±171.4 (p <0.0001), respectively. Increasing quartiles of LCn-3PUFA intake were associated with widening of mean retinal arteriolar caliber among 17-year old girls ~3.9 μm (multivariable-adjusted P-trend = 0.001). Girls who consumed ≥2 serves of fish/week versus those who did not had ~2.1 μm wider retinal arterioles (p = 0.03). No associations were observed among boys or with retinal venules. Mean dietary intakes of LCn-3 PUFA increased during adolescence, but are still below recommended levels of consumption. These results suggest that LCn-3 PUFA and fish intake might have a beneficial influence.

Abstract
Background Pulse-wave velocity (PWV) measures aortic stiffness. It is an independent predictor of cardiovascular events and mortality, yet there is paucity in the literature on its association with the severity and extent of coronary artery disease (CAD). Methods To examine the utility of PWV in predicting CAD burden in men and women the PWV was determined in 344 patients (Men = 266, Women = 78) presenting for invasive coronary angiography for the assessment of suspected CAD. Pearson correlations and multivariate analysis were used to evaluate the relationship between these coronary scores, PWV and traditional cardiovascular risk factors. Results Compared to men, women with chest pain had lower mean Extent scores (19.2 vs. 35.6; p = 0.0001) and Gensini scores (23.6 vs. 41.9; p = 0.0001). PWV was similar between men and women (12.35 ± 3.74 vs. 12.43 ± 4.58; p = 0.88) and correlated with Extent score (r = 0.21, p = 0.0001) but not Gensini or vessel score (r = 0.03, p = 0.64 and r = 0.06, p = 0.26, respectively). PWV was associated with Extent score in men (B = 2.25 ± 0.78, p = 0.004 for men and B = 1.50 ± 0.88, p = 0.09 for women). It was not a predictor of Gensini score (B = -0.10, P = 0.90). Conclusion PWV correlates with the extent of CAD, as measured by the ‘Extent’ score in men more than women. However, it does not correlate with the severity of obstructive CAD in either gender.

Abstract
We aimed to assess the association between dairy product consumption and calcium intake with the prevalence and 10-year incidence of chronic kidney disease (CKD). 1185 participants aged ≥50 years at baseline were examined between 1992–4 and 2002–4. Dietary data were collected using a food frequency questionnaire, and servings of dairy food consumption were calculated. Baseline biochemistry including serum creatinine was measured. CKD was defined as Modification of Diet in Renal Disease Study estimated glomerular filtration rate <60 mL·min−1.1.73 m−2. Cross-sectional analysis showed that older adults in the highest quintile compared to the lowest quintile (reference group) of low/reduced fat dairy food consumption had reduced odds of CKD, multivariable-adjusted odds ratio, OR, 0.64 (95% confidence intervals, CI, 0.43–0.96). Increasing total intake of dietary calcium was associated with reduced odds of CKD (P-trend = 0.02); comparing highest versus lowest quintile: OR 0.62 (95% CI 0.42–0.92). Participants in the second versus first quintile of low/reduced fat dairy food consumption at baseline had 49% reduced risk of CKD 10 years later, OR 0.51 (95% CI 0.29–0.89). Higher consumption of low/reduced fat dairy foods was independently associated with lower risk of CKD. Additional population-based studies are warranted to confirm these findings.

Abstract
BACKGROUND Prior studies have suggested the association between incidence of coronary artery disease (CAD) with chronic kidney disease (CKD) and poor glomerular filtration function. However to the best of our knowledge, few studies have specifically assessed this relationship based on the severity of CAD as quantified using Extent and Gensini scores. METHODS Between June 2009 and January 2012, data were collected from 1,680 participants as part of the Australian Heart Eye Study (AHES) cohort. Coronary angiograms were scored according to Gensini (severity) and Extent scores. Retinal vessel calibres were measured using validated semi-automated software. Potential confounders were adjusted for using multivariate analysis. RESULTS There were no significant associations found between CKD status with Extent and Gensini scores for CAD severity, both unadjusted and when adjusted for confounding factors. In unadjusted analyses, a significant association between CKD and narrower retinal arteriolar diameter was observed (P=0.0072). After multivariate adjustment, the association between CKD and retinal arteriolar diameter was attenuated and was no longer significant (P=0.1466). No associations were observed between retinal venular calibre and prevalent CKD. CONCLUSIONS The present study demonstrated no independent associations between CKD and CAD severity. These results warrant validation by future large, prospective longitudinal studies.

Abstract
BACKGROUND There is increasing evidence that a considerable proportion of patients with diabetes remain undiagnosed and untreated, however, it is unclear whether this is associated with more severe coronary artery disease (CAD) and microvasculature changes compared with diagnosed patients. We assessed CAD extent and severity, along with changes to the retinal microvascular structure in participants with undiagnosed versus diagnosed type 2 diabetes. METHODS Participants of the Australian Heart Eye Study were stratified into participants with previously diagnosed diabetes (n=489), undiagnosed diabetes (n=76) and no diabetes (n=1,112). Retinal vessel caliber was measured from digital retinal images. Extent and severity of CAD was assessed using Extent and Gensini scores from angiography findings, respectively. RESULTS Participants with undiagnosed and diagnosed diabetes versus those with no diabetes (reference group) had increased odds of being in the highest quartile of Gensini scores, multivariate adjusted odds ratios (OR) =7.02 [95% confidence interval (CI), 2.04-24.1] and OR =2.76 (95% CI, 1.67-4.55), respectively. Participants with undiagnosed and diagnosed diabetes versus those with no diabetes also had increased odds of being in the highest quartile of Extent scores, multivariate adjusted OR =7.63 (95% CI, 2.15-27.10) and OR =3.72 (95% CI, 2.22-6.27), respectively. No significant differences were observed in retinal vessel caliber between participants with undiagnosed versus diagnosed diabetes. CONCLUSIONS The present study demonstrated that participants with undiagnosed diabetes compared to those with previously diagnosed diabetes, had a stronger likelihood of having more severe and extensive CAD. However, retinal microvascular signs did not differ by diabetes status.

Abstract
BACKGROUND concurrent vision and hearing loss are common in older adults; however, epidemiological data on their relationship with the incidence of falls are lacking. OBJECTIVE we assessed the association between dual sensory impairment (DSI) and incidence of falls. We examined the influence of self-perceived hearing handicap and hearing aid use and risk of falls. DESIGN a population-based, cohort study of participants followed over 5 years. SETTING Blue Mountains, west of Sydney, Australia. SUBJECTS one thousand four hundred and seventy-eight participants aged 55 and older at baseline were included in longitudinal analyses. METHODS visual impairment was defined as presenting or best-corrected visual acuity less than 20/40 (better eye), and hearing impairment as average pure-tone air conduction threshold >25 dB HL (500-4,000 Hz, better ear). The shortened version of the hearing handicap inventory for the elderly was administered. Incident falls were assessed over the 12 months before each visit. Cognitive impairment was determined using the Mini-Mental State Examination. RESULTS five-year incidence of falls was 10.4%. Participants with severe self-perceived hearing handicap versus no hearing handicap had increased risk of incident falls, multivariable-adjusted OR 1.93 (95% confidence intervals, CI, 1.02-3.64). Hearing aid users versus non-users had 75% increased likelihood of incident falls. Participants with co-existing best-corrected visual impairment and mild hearing loss (>25 to ≤40 dB HL) had higher odds of incident falls, OR 2.19 (95% CI 1.03-4.67). After excluding persons with cognitive impairment, this association did not persist. CONCLUSION these epidemiological data show that DSI in older adults could significantly increase their risk of falling.

Abstract
The presence of visual impairment (VI) and hearing loss (HL) with may be a marker for subsequent cognitive decline over time in older people. A prospective, longitudinal population-based study of the 3654 participants of the Blue Mountains Eye Study were assessed for the associations between VI and HL and a decline in mini-mental state examination (MMSE) scores over a duration of 10 years from the 5-year (baseline of this report) to the 15-year follow-up visits. MMSE was assessed at the 5-, 10- and 15-year follow-up visits. A decline ≥3 scores from 5-year to 10- or 15-year visits indicated possible cognitive decline. VI was defined as best-corrected visual acuity <6/12 in the worse-eye, HL was defined as pure-tone average >40 decibels in the worse-ear and dual sensory impairment (DSI) was defined by the co-presence of VI and HL, detected at 5-year follow-up (baseline of this report). Participants with no VI and HL over the same 5- or 10-year corresponding period were controls. Associations of VI, HL and DSI with possible cognitive decline were assessed using logistic regression models adjusting for age and sex after excluding subjects with a stroke history. The presence of VI, HL or DSI was not associated with possible cognitive decline over 5 years (odds ratio (OR) 0.84, 95% confidence-intervals (CI) 0.40-1.79, OR 1.02, 95% CI 0.61-1.70 and 1.41, 95% CI 0.54-3.72, respectively) or 10 years (OR 1.09, 95% CI 0.52-2.30, OR 1.09, 95% CI 0.65-1.82 and 1.15, 95% CI 0.28-4.73, respectively). There were no changes to these findings after adjustment for other potential confounders. Age was significantly associated with possible cognitive decline (OR 1.07, 95% CI 1.04-1.10 for both periods). Neither visual impairment, hearing loss nor dual sensory impairment was independently associated with subsequent decline in cognition.

Abstract
Background There is evidence to suggest that microvascular disease, particularly diabetic retinopathy, plays a role in the pathogenesis of HF. However, whether changes in retinal vessel calibre predicts HF is unclear. The purpose of this study was to examine the association of retinal microvascular structure with prevalent heart failure (HF). Methods The Australian Heart Eye Study (AHES) is a cross-sectional study that surveyed 1680 participants who presented to a tertiary referral hospital for the evaluation of potential coronary artery disease by coronary angiography. Retinal vessel calibre was graded using retinal photography and participants’ self-reported echocardiography-confirmed HF was obtained via an extensive medical questionnaire. Results There were 107 participants (8.1%) with prevalent self-reported HF. Persons with wider retinal arteriolar calibre (comparing highest versus lowest tertile or reference) were more likely to have prevalent HF (OR 3.5; 95% CI, 1.7–7.2) when adjusted for age and sex. After further adjustment for body mass index, hypertension, diabetes, smoking status, triglycerides and estimated glomerular filtration rate, this association remained significant (OR 4.5; 95% CI, 2.0–9.8). After further stratification, this association remained significant among participants with diabetes (OR 10.3; 95% CI, 2.7–39.3) but not in those without diabetes (OR 2.7; 95% CI, 0.9–7.5). The strength of this association was not dependent on the length of history of diabetes, or retinopathy status. There was no significant association between retinal venular calibre and prevalence of HF. Conclusions Wider retinal arteriolar diameter was significantly and independently associated with prevalent HF in participants of a cross-sectional study. This association was significant stronger among participants with diabetes compared to without diabetes. No association was found between retinal venule calibre with prevalent HF.

Abstract
OBJECTIVE We aimed to investigate the independent association between AMD and risk of ischemic heart disease (IHD), stroke, and cardiovascular (CVD) mortality, and all-cause mortality over 15 years. METHODS 3654 participants aged 49+ years at baseline were followed over 15 years. AMD was assessed from retinal photographs. Deaths and cause of death were confirmed by data linkage with the Australian National Death Index. Hazard ratios (HRs) and 95% confidence intervals (CIs) were assessed using Cox models. RESULTS 71.4% (n=162) and 34.6% (n=1037) of participants with any AMD and no AMD, respectively, died over 15 years. After multivariable-adjustment, no significant associations were observed between AMD and total- and cause-specific mortality in the overall cohort. However, among men, late AMD at baseline was associated with an increased risk of all-cause mortality (n=22; 95.7%), 15 years later: multivariable-adjusted HR, 1.80 (95% CI 1.04-3.11). Women with late AMD had 2-fold increased risk of stroke mortality (n=15; 28.9%), HR 2.10 (95% CI 1.08-4.06). Early-stage AMD was not associated with mortality risk. CONCLUSION Late AMD independently predicted all-cause mortality in men and stroke mortality in women, over 15 years. Although underlying mechanisms are unclear, these findings indicate that late AMD is a marker of biological aging.

Abstract
PURPOSE Decreased smell could cause appetite suppression and malnutrition. However, there is a paucity of longitudinal data between olfaction and nutritional status in older adults. We aimed to prospectively examine the relationship between olfactory impairment and overall diet quality (reflecting adherence to dietary guidelines) in a population-based cohort of older adults. METHODS We used 5-year follow-up data from 557 adults (aged 60+ years at baseline) whose olfaction was measured using the San Diego Odor Identification Test (SDOIT). Dietary data were collected using a validated semiquantitative food frequency questionnaire. A total diet score (TDS) was calculated for intake of selected food groups and nutrients for each participant as described in the national dietary guidelines. Final scores ranged from 0 to 20; higher scores indicated closer adherence to dietary guidelines. RESULTS After adjusting for all potential confounders, older adults with moderate/severe olfactory impairment (SDOIT score ≤ 3; lower scores indicate impairment) compared with those with no olfactory impairment had significantly lower adjusted mean (±SE) TDS, 9.09 (0.40) versus 9.94 (0.10), p = 0.04. Women with moderate/severe impaired olfaction (i.e., scored poorly on the odor identification test) compared with those with normal olfaction had significantly lower adjusted mean TDS, 8.87 (0.69) versus 10.31 (0.13), p = 0.04. No associations were observed between olfaction and TDS in men. CONCLUSIONS Olfactory impairment in older women could signal an increased risk of poorer diet quality, defined as adherence to national dietary guidelines. Additional longitudinal studies are needed to confirm or refute the observed link between olfactory loss and overall patterns of food intake in older adults.

Abstract
AIMS To describe the prevalence of idiopathic and secondary epiretinal membranes (ERM) in a clinical cohort (Australian Heart Eye Study, AHES) and compare to the Blue Mountains Eye Study, and to determine whether associations exist between idiopathic ERM and the extent and severity of coronary artery disease (CAD). METHODS The AHES is an observational study that surveyed 1680 participants who presented to a tertiary referral hospital for the evaluation of potential CAD by coronary angiography. Severity and extent of CAD was assessed using three scoring systems: (1) segment/vessel scores, (2) Gensini and (3) extent scores. Two types of ERM were identified: a more severe form, termed 'preretinal macular fibrosis' (PMF) in which retinal folds were identified; and a less severe form termed 'cellophane macular reflex' (CMR), without visible retinal folds. RESULTS Overall prevalence of ERM was 7.0% (n=115), with CMR and PMF each 3.5%. 72.7% of ERM cases were idiopathic (no secondary cause identified). Prevalence of PMF, but not CMR, was significantly higher than the corresponding age-standardised prevalence in the baseline Blue Mountains Eye Study (p<0.001). There was no significant association between extent and severity of CAD and idiopathic ERM. CONCLUSIONS This study suggests that cardiovascular disease (specifically severity and extent of CAD) is not associated with ERM. However, there may be a greater prevalence of severe ERM (PMF) in a high cardiovascular risk cohort relative to a population-based cohort.

Abstract
Coffee, a major dietary source of caffeine, is among the most widely consumed beverages in the world and has received considerable attention regarding health risks and benefits. We conducted a genome-wide (GW) meta-analysis of predominately regular-type coffee consumption (cups per day) among up to 91,462 coffee consumers of European ancestry with top single-nucleotide polymorphisms (SNPs) followed-up in ~30 062 and 7964 coffee consumers of European and African-American ancestry, respectively. Studies from both stages were combined in a trans-ethnic meta-analysis. Confirmed loci were examined for putative functional and biological relevance. Eight loci, including six novel loci, met GW significance (log10Bayes factor (BF)>5.64) with per-allele effect sizes of 0.03-0.14 cups per day. Six are located in or near genes potentially involved in pharmacokinetics (ABCG2, AHR, POR and CYP1A2) and pharmacodynamics (BDNF and SLC6A4) of caffeine. Two map to GCKR and MLXIPL genes related to metabolic traits but lacking known roles in coffee consumption. Enhancer and promoter histone marks populate the regions of many confirmed loci and several potential regulatory SNPs are highly correlated with the lead SNP of each. SNP alleles near GCKR, MLXIPL, BDNF and CYP1A2 that were associated with higher coffee consumption have previously been associated with smoking initiation, higher adiposity and fasting insulin and glucose but lower blood pressure and favorable lipid, inflammatory and liver enzyme profiles (P<5 × 10(-8)).Our genetic findings among European and African-American adults reinforce the role of caffeine in mediating habitual coffee consumption and may point to molecular mechanisms underlying inter-individual variability in pharmacological and health effects of coffee.

Abstract
We aimed to prospectively assess dairy intake among adolescents, and determine the predictors of adequate dairy consumption during adolescence. 634 Sydney schoolchildren (351 girls and 283 boys) who had dietary data at both age 12 and 17 were included for analyses. Dairy consumption was assessed from validated semi-quantitative food frequency questionnaires. At age 12, mean total dairy intake was 1.62 serves/day which decreased to 1.40 by age 17 (p<0.0001). Mean serves/day of milk decreased from 1.11 to 0.92 during adolescence. Moreover, 90% of the decrease in serves/day of total dairy was due to reduced milk consumption. At age 12, 8.5% of children consumed >=3.5 serves/day of total dairy and this decreased to 6.2%, 5 years later at age 17 (p=0.001). A lower proportion of girls compared with boys consumed >=3 serves/day of total dairy at both ages 12 (p=0.005) and 17 (p=0.01). Participants with tertiary qualified parents at baseline were 85% more likely to have intakes of the dairy food group above the median during the 5 years, OR 1.85 (95% CI 1.18-2.91). Frequent flavored milk consumption (>=2 serves/week) at baseline was associated with ~5-fold greater likelihood of maintaining intakes of dairy foods above the median during adolescence. Dairy food consumption decreased significantly during adolescence, driven primarily by a decrease in milk consumption. Most adolescents did not meet national recommended guidelines for the dairy food group intake. These findings highlight the need for further research into intervention strategies aimed at sustaining dairy consumption.

Abstract
PURPOSE There is uncertainty in the published literature as to whether physical activity should be advocated for age-related macular degeneration (AMD) prevention. We aimed to assess prospectively the association between physical activity and the 15-year incidence of AMD in older adults. METHODS We assessed AMD from retinal photographs. Participants provided details of walking exercise and the performance of moderate or vigorous activities, which were used to calculate metabolic equivalents (METs). RESULTS After adjusting for age, adults aged ≥ 75 years in the highest tertile (the most physically active) compared to those in the lowest tertile (least physically active) were 79% less likely to have incident late AMD over the 15 years (odds ratio [OR], 0.21; 95% confidence intervals [CI], 0.05-0.95). However, after further adjusting for sex, body mass index, smoking, fish consumption, and white cell count, this association was no longer statistically significant (OR, 0.26; 95% CI, 0.06-1.28). Significant associations were not found in those aged <75 or with the 15-year cumulative incidence of early AMD. CONCLUSIONS Physical activity did not influence the risk of AMD over 15 years in older adults, independent of diet, smoking, white cell count, and body mass index.
