RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

The present study aimed to assess the longitudinal associations of coffee and tea consumption with metabolic syndrome and its component conditions in a group of Australian older adults who participated in the Blue Mountains Eye Study (n 2554, mean age: 64 years, 43 % female). Participants' coffee and tea intake were measured using a validated food frequency questionnaire. Hazard ratios (HRs) over a 10-year period were estimated using Cox hazard regression models adjusting for lifestyle factors. Results showed that coffee consumption was not associated with the incidence of metabolic syndrome, high fasting glucose, high triglycerides, central obesity, high blood pressure and low HDL-cholesterol (HDL-C). Tea consumption was not associated with incidence of metabolic syndrome and the component conditions except for the risk of having low HDL-C, in which a nominally inverse association was observed (multivariate-adjusted HR at 2-3 cups/d: 0⋅48, 95 % CI 0⋅26, 0⋅87, P = 0⋅016; 4 cups/d or more: 0⋅50, 95 % CI 0⋅27, 0⋅93, P = 0⋅029). After stratifying for fruit consumption (P interaction between tea and fruit = 0⋅007), consuming four cups of tea per day was nominally associated with lower incidence of metabolic syndrome among those with high fruit consumption (multivariable-adjusted HR: 0⋅44, 95 % CI 0⋅20, 0⋅93, P = 0⋅033). Our results did not support a significant association between tea and coffee consumption and metabolic syndrome. Tea consumption may be associated with a lower risk of having low HDL-C, while high tea and fruit consumption together may be associated with a lower risk of developing metabolic syndrome.

RESUMEN

OBJECTIVES: We examined the association between birthweight and objectively measured hearing loss in older men and women. STUDY DESIGN: 893 community-dwelling participants aged 50+ years with pure-tone audiometry data and self-reported birthweight were included for cross-sectional analysis. Participants were asked how much they weighed at birth either in pounds and ounces or in kilograms and grams. MAIN OUTCOME MEASURES: 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. RESULTS: Around 31.9% and 50.0% of participants who self-reported low (<2.5 kg) and high birthweight (>4.5 kg), respectively, had hearing loss. The odds of experiencing any level of hearing loss (>25 dB HL) after multivariate adjustment was: OR 2.00 (95% CI 1.13-3.56) for low birthweight and OR 2.43 (95% CI 1.23-4.82) for high birthweight, compared with participants in the reference group who self-reported normal birthweight (3.1-4.0 kg). Additionally, participants with high birthweight had 2.4-fold greater odds of having mild hearing loss (25-40 dB HL), while participants with low birthweight had 2.6-fold greater odds of moderate to severe hearing loss. CONCLUSIONS: We observed an independent U-shaped association between birthweight and age-related hearing loss, that is, persons born with low or high birthweight had a greater likelihood of experiencing any level of hearing loss in older age. These findings provide further evidence to address an important gap in the literature regarding the influence of foetal growth on the auditory system in later life.

RESUMEN

PURPOSE: Dietary flavonoids are bioactive compounds that have been widely investigated for their associations with vascular health outcomes. As the development of tinnitus has been linked to vascular pathways, dietary flavonoids may have role in the prevention of tinnitus symptoms. This study reports the associations between the intakes of major classes of dietary flavonoids and 10-year incidence of tinnitus. METHODS: Of the 1753 participants (aged ≥ 50 years) from the Blue Mountains Hearing Study with complete baseline data on tinnitus symptoms and dietary intakes, 536 (31%) cases of tinnitus were identified and excluded from further analysis. Dietary data was collected using a semi-quantitative food frequency questionnaire and intakes of the five major classes of flavonoids were determined using U.S. Department of Agriculture flavonoid databases. Presence of prolonged tinnitus was assessed by a positive response to a single question administered by an audiologist. RESULTS: Of the remaining 1217 participants without tinnitus at baseline, 222 (18%) incident cases of tinnitus were identified over 10 years. After age-sex adjustment, participants in the third versus first quartile of proanthocyanidin intake were significantly less likely to develop incident tinnitus by 36% (HR = 0.64; 95% CI 0.43-0.96, Ptrend = 0.04). Following multivariable adjustment, this protective trend was non-significant (HR = 0.60; 95% CI 0.39-0.92; Ptrend = 0.06). Similarly, a non-significant protective trend was observed when comparing the fourth versus first quartile of intake of all flavonoids (OR = 0.61; 95% CI 0.39-0.96). No other associations were observed. CONCLUSION: Our findings do not support the hypothesis that dietary flavonoids are protective against the development of tinnitus over 10 years. The weak significant association observed between proanthocyanidin and incident tinnitus may be a chance finding as there was no significant trend following multivariate adjustments and, therefore, requires further studies to investigate these associations.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

PURPOSE: To assess whether dietary intake of flavonoids are associated with longitudinal treatment outcomes of patients with neovascular age-related macular degeneration (nAMD). METHODS: 547 participants with nAMD were recruited at baseline, 494 were followed-up after receiving 12 months of anti-vascular endothelial growth factor (anti-VEGF) therapy. Baseline dietary intake of flavonoids was determined using a validated food frequency questionnaire. At follow-up, presence of intra-retinal and sub-retinal fluid (IRF and SRF), retinal pigment epithelium detachment and measurements of central macular thickness (CMT) were recorded from optical coherence tomography scans. Visual acuity (VA) was documented using LogMAR charts. RESULTS: Participants in the first tertile of intake of the flavonol quercetin, and the flavan-3-ols epigallocatechin-3-gallate and epigallocatechin had significantly worse vision than participants in the third tertile-multivariable-adjusted least square (LS) mean VA: 14.68 vs. 19.53 (p = 0.04); 14.06 vs. 18.89 (p = 0.04); 13.86 vs. 18.86 (p = 0.03), respectively. Participants in the first compared to the third tertile of flavan-3-ol, epigallocatechin-3-gallate and epigallocatechin intake all had a twofold higher risk of IRF, multivariable-adjusted p trend of: 0.03, 0.01 and 0.02, respectively. The first vs. the third tertile of tea intake had significantly worse vision (LS mean VA: 13.49 vs. 19.04, p = 0.02), increased risk of IRF (OR 2.13, 95% CI 1.18-3.85) and greater mean CMT (279.59 µm vs. 256.52 µm, p = 0.04). CONCLUSIONS: Higher intakes of dietary flavonoids, specifically flavonols and flavan-3-ols, could be associated with better long-term treatment outcomes in nAMD patients receiving anti-VEGF therapy. Confirmation of these associations in interventional studies could result in promising new therapeutic approaches to the treatment of nAMD.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Dietary flavonoids are vasoactive phytochemicals with promising anti-inflammatory properties. We aimed to assess the associations between baseline intakes of six commonly consumed flavonoid subclasses and 10-year incidence of age-related hearing loss. At baseline, 1691 participants aged 50+ years had information on dietary intakes and hearing status. Hearing loss was defined as the pure-tone average of frequencies 0.5, 1.0, 2.0, and 4.0 kHz > 25 dB hearing level (HL). Dietary data were collected through a semi-quantitative food frequency questionnaire. The flavonoid content of foods was estimated using US databases. During the 10-year follow-up, 260 (31.6%) new cases of hearing loss (incident) were observed. After multivariable adjustment, participants in the fourth versus first quartile (reference group) of intake of dietary isoflavone had 36% lower risk of incident hearing loss after 10 years: odds ratios (OR) 0.64 (95% confidence intervals, CI, 0.42-0.99); p-value for trend = 0.03. Nonsignificant associations were observed between the other five flavonoid subclasses and 10-year incidence of hearing loss. Our findings do not support the hypothesis that the intake of dietary flavonoids protect against long-term risk of hearing loss. The association with isoflavone intake needs to be confirmed by other population-based studies.

RESUMEN

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.

RESUMEN

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 ß-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 ß-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 ß-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.

RESUMEN

BACKGROUND AND AIMS: A naturally rich source of lutein and zeaxanthin are eggs. There is scarce epidemiological data on the temporal association between total egg consumption and age-related macular degeneration (AMD) incidence. We aimed to establish the prospective and independent association between consumption of eggs with the incidence of AMD over a 15-year follow-up. METHODS: In this population-based cohort study of 3,654 participants aged 49 + years examined at baseline, 2034 participants had complete information on baseline egg consumption and AMD signs over 15 years. AMD was determined from retinal photographs. Egg consumption was assessed using a semi-quantitative food-frequency questionnaire. Total egg intake was calculated through summing up intakes in all forms e.g. boiled, poached, fried, scrambled and/or omelette. We summarized total egg consumption into the following categories: ≤1 egg/week; 2-4 eggs/week; 5-6 eggs/week; and ≥1 egg/day. RESULTS: At baseline, participants who consumed 2-4 eggs/week compared to those who consumed ≤1 egg/week (reference group) had reduced risk of incident late-stage AMD after 15 years: multivariable-adjusted odds ratio, OR, 0.51 (95% confidence intervals, CI, 0.28-0.92). Participants who consumed 2-4 eggs/week versus ≤1 egg/week at baseline had 62% reduced risk of developing neovascular AMD. Among those whose AMD onset was at or before the 10-year follow-up, consumption of 2-4 and 5-6 eggs/week was associated with 54% and 65% reduced risk of incident late AMD, respectively. When analyzed as a dichotomized variable, participants who consumed >1 egg/week versus ≤1 egg/week at baseline, had 46% reduced risk of developing late-stage AMD 15 years later: multivariable-adjusted OR 0.54 (95% CI 0.3-0.90). Non-significant associations were observed between egg consumption and incident early AMD. CONCLUSIONS: Our findings suggest that moderate consumption of eggs significantly reduces the risk of developing incident late-stage AMD over 15 years.
