Shen X, Chen X, Chen X, Li Z, Lin J, Huang H, Xie R, Li Y, Zhu Y, Zhuo Y. Association of vision and hearing impairment and dietary diversity among the oldest old in China: findings from the Chinese longitudinal healthy longevity survey. BMC Public Health 2024; 24:1997. [PMID: 39060927 PMCID: PMC11282864 DOI: 10.1186/s12889-024-19482-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2024] [Accepted: 07/15/2024] [Indexed: 07/28/2024] Open
Abstract
BACKGROUND The presence of sensory impairment among older age cohorts exerts a significant impact on both individuals and society generally. Although the impact of dietary patterns on health is vital across all stages of life, there still a paucity of comprehensive research on the association between dietary variety and sensory impairments. OBJECTIVE To investigate the potential relationship between dietary diversity and the prevalence of visual and hearing impairment or dual sensory impairments (visual and hearing impairment) among the oldest old population. METHODS This is a cross-sectional study relied on data obtained from the 2018 survey conducted by the Chinese Longitudinal Healthy Longevity Survey (CLHLS). Subjects aged 80 and older with complete vision and hearing data were included in the study. Multivariate logistic regression models were developed to examine the association between dietary components and visual and hearing impairment while controlling for age, gender, socioeconomic demographic factors, living habits, other food habits, and general health status. RESULTS The study included 10,093 participants, with an average age of 92.29 ± 7.75 years. Vision and hearing function were assessed based on the ability to distinguish the direction of the break in the circle and the requirement for hearing aids, respectively. Upon controlling for confounding variables, individuals with a greater Dietary Diversity Score (DDS, the number of food groups, range: 1-11) had a reduced likelihood of experiencing visual impairment (odds ratio [OR] = 0.944, 95% confidence interval [CI], 0.915-0.974) and dual sensory impairment (OR = 0.930, 95% CI, 0.905-0.955). In comparison to the low dietary variety group (insufficient dietary diversity, DDS < 4), the high dietary diversity group (sufficient dietary diversity, DDS ≥ 4) exhibited a decreased risk of visual impairment (OR = 0.820, 95% CI, 0.713-0.944) and dual sensory impairment (OR = 0.751, 95% CI, 0.667-0.846). However, no statistically significant correlation was observed between dietary diversity and the presence of only hearing impairment (OR = 0.924, 95% CI, 0.815-1.047) (P < 0.05). CONCLUSIONS AND IMPLICATIONS: The synthesis of research findings suggests that following diverse dietary patterns and healthy nutritional practices may be an effective and affordable way to prevent age-related decline in visual impairment and dual sensory impairment.

Abstract
Background and aim Nutrition plays a vital role in maintaining and improving vision health. However, little is known about dietary intake habits and their correlation with vision health among adults in the Kingdom of Saudi Arabia (KSA). The present survey was aimed to assess dietary patterns and vision health among Saudi adults and to determine the association between dietary patterns and vision health. Methods The present analytical study was carried out among 1,234 Saudi adults in the Makkah, Riyadh, and Qassim regions of KSA. We used the Arabic version of the National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) and the diet quality screener (DQS). We applied Mann-Whitney U and Kruskal-Wallis tests to determine the association between vision function score and demographic characteristics. Furthermore, the Spearman correlation test was used to determine the relationship between the DQS and the NEI VFQ-25. Results Of the studied population, the highest score obtained through the NEI VFQ-25 was in the social function domain (mean ± SD = 76.64 ± 18.63), followed by the general vision domain (mean ± SD = 75.21 ± 15.16) and was negatively correlated with age. Regarding dietary patterns, the intake of lean protein sources per week was the highest, with a mean intake of 4.17 days per week, followed by that of whole grains and milk or dairy products, with a mean intake of around four days per week. There was a significant correlation between various dietary intakes and visual function scores. Conclusion The present survey underscores the significance of understanding regional dietary patterns and their implications for vision health. Furthermore, our study's findings indicate a need for targeted nutritional intervention measures to improve the vision health of this population.

Abstract
As the most serious of the many worse new pathological changes caused by diabetes, there are many risk factors for the occurrence and development of diabetic retinopathy (DR). They mainly include hyperglycemia, hypertension, hyperlipidemia and so on. Among them, hyperglycemia is the most critical cause, and plays a vital role in the pathological changes of DR. High-sucrose diets (HSDs) lead to elevated blood glucose levels in vivo, which, through oxidative stress, inflammation, the production of advanced glycation end products (AGEs) and vascular endothelial growth factor (VEGF), cause plenty of pathological damages to the retina and ultimately bring about loss of vision. The existing therapies for DR primarily target the terminal stage of the disease, when irreversible visual impairment has appeared. Therefore, early prevention is particularly critical. The early prevention of DR-related vision loss requires adjustments to dietary habits, mainly by reducing sugar intake. This article primarily discusses the risk factors, pathophysiological processes and molecular mechanisms associated with the development of DR caused by HSDs. It aims to raise awareness of the crucial role of diet in the occurrence and progression of DR, promote timely changes in dietary habits, prevent vision loss and improve the quality of life. The aim is to make people aware of the importance of diet in the occurrence and progression of DR. According to the dietary modification strategies that we give, patients can change their poor eating habits in a timely manner to avoid theoretically avoidable retinopathy and obtain an excellent prognosis.

Abstract
BACKGROUND Considering their prevalence and burden, information on the sensory impairment etiology is essential. Links between nutrition and sensory impairment through inflammation have been suggested. Although the decline in sensory capacities is age-related, few research included a geriatric population. AIMS Exploring the associations of nutrition with sensory capacities and test inflammation as a mediator among cognitively and physically impaired older adults. METHODS Cross-sectional data from the COGFRAIL cohort, including 164 participants with no hearing aid and 20 participants wearing no visual aid. Hearing was evaluated using the Hearing Handicap Inventory for the Elderly-screening version (on 40 points, the lower the better), and the Monoyer chart (one to ten out of ten points, the higher the better), and the Parinaud scale (from 1.5, the best, to 28 points, the worst) assessed distant and near vision, respectively. Dietary intake was assessed through a diet history interview and inflammation was measured by the C-Reactive Protein level. Multivariate linear regressions were performed and Structural Equation Modeling (SEM) framework was used to explore the potential mediation effect of inflammation on the diet-hearing relationships. RESULTS None of the nutrients was significantly associated with hearing acuity in the regressions or the SEM model. Regarding vision, a higher intake of saturated fatty acids was related to lower long-distance visual acuity, and greater Omega-3 consumption was associated with better near-vision capacity. DISCUSSION No nutrient was associated with hearing capacity and relationships between fatty acids quality and vision acuity were suggested. CONCLUSION These exploratory results require further investigations.

Abstract
Implementation of eye care behaviors may reduce the risk of eye symptoms and diseases. This study aimed to assess eye care behaviors and identify factors associated with eye care practices among adults in Poland. This cross-sectional survey was carried out between 9 and 12 December 2022 on a nationwide random quota sample of adults in Poland. The study questionnaire included a set of questions on 10 different eye care behaviors. The study population included 1076 participants with a mean age of 45.7 ± 16.2 years, and 54.2% of participants were females. The most common (30.2%) eye care behavior was the use of good lighting indoors, and 27.3% used sunglasses with a UV filter. More than one-fifth of participants declared taking regular screen breaks and limiting screen time. Less than one-tenth of participants used dietary supplements with lutein, beta-carotene, or zinc. Out of 12 factors assessed in this study, self-reported knowledge of eye diseases was the most important factor associated (p < 0.05) with eye care behaviors. There were no economic or educational gaps (p > 0.05) in the implementation of most of the eye care behaviors among adults in Poland. This study revealed a low level of implementation of eye care behaviors among adults in Poland.

Abstract
BACKGROUND Healthy Eating Index-2015 (HEI-2015), a healthy eating pattern proposed by Dietary Guidelines for Americans, is proven to be protective against various diseases. However, whether it is associated with age-related cataracts is unknown. METHODS This population-based cross-sectional study included 6395 participants from the National Health and Nutrition Examination Survey (NHANES) in the cycles from 2005 to 2008. HEI-2015 was calculated from 24-h dietary recall interviews, ranging from 0 to 100, and higher HEI-2015 represents better diet quality. Age-related cataract was generated from the questionnaire. The association between HEI-2015 and cataract was assessed with logistic regression models. Propensity score weighting, restricted cubic spline, and subgroup analysis were conducted to further explore the relationship. RESULTS 6395 participants were included in the study, with a mean [standard deviation (SD)] age of 48.7 (15.3) years and 3115 (48.7%) being male. HEI-2015 was negatively associated with cataracts after adjusting all covariates included, both as a continuous variable [odds ratio (OR): 0.991, 95% confidence interval (CI): 0.984-0.997, p = 0.006] and quartiles with the highest quartile compared to the lowest (OR: 0.739, 95% CI: 0.559-0.980, p = 0.035). After propensity score weighting, the association remained significant. Restricted cubic spline revealed no non-linear relationship (p for non-linearity 0.085). Subgroup analysis showed that there were no interaction effects. CONCLUSIONS Adherence to the healthy eating pattern, HEI-2015, was associated with a lower risk of age-related cataracts.

Abstract
Introduction: Visual impairment is a major public health challenge for diabetics who have ocular comorbidities. In Ethiopia, data are lacking on the prevalence of visual impairment among diabetics as well as information on causes and predisposing factors. The current study was designed to assess the causes, risk factors, and levels of diabetes-related visual impairment within an Ethiopian population. Methods: The study enrolled a total of 296 diabetic patients at the Debre Tabor General Hospital (DTGH). Data were ascertained through face-to-face interview, from patients’ medical folder, and through comprehensive ocular health assessment. Descriptive and analytical statistics were performed. Result: Generally, the prevalence of visual impairment among adult diabetic patients was 39.5% (95% confidence interval [CI]: 33.8–45.6). Visual impairment was primarily due to diabetic retinopathy (44.4%), followed by refractive error (20.6%), cataract (13.9%), other ocular conditions (6.1%), and glaucoma (5.4%). Age >45 years (adjusted odds ratio [AOR] = 7.8, 95% CI: 3.5–18), female gender (AOR = 3.0, 95% CI: 1.4–7.7), low educational status (AOR = 8.1, 95% CI: 2.4–26.0), and longer span of diabetes (AOR = 3.7, 95% CI: 2.1–6.8) had a notable association with visual impairment among diabetic patients. Discussion: This study observed a high prevalence of visual impairment in diabetic patients. Diabetic retinopathy, refractive error, and cataract were the most common causes of visual impairment, followed by other ocular conditions and glaucoma. Older age, female gender, low educational status, and longer span of diabetes were important risk factors of visual impairment among diabetic patients. Implications for Practitioners: This result could alert health care professionals to inform their diabetic clients about the serious impacts of diabetes and the need for a regular eye check-up. Health care providers and policy makers should work to integrate the diabetic clinics into a general hospital with an eye care unit for an effective screening of diabetic eye disease and prevention of blindness.

Abstract
PURPOSE To test the hypothesis that food insecurity is associated with greater prevalence of vision impairment (VI). DESIGN Cross-sectional, nationally representative survey of US adults. METHODS Adults 50 years and older were included. Food security category (ie, full, marginal, low, or very low) was assessed by the US Household Food Security Survey Module. Objective presenting VI (PVI) and self-reported VI (SRVI) were assessed by examination and survey, respectively. Separate logistic regression models were constructed with food insecurity category as a predictor of PVI or SRVI. Models were adjusted for age, gender, race, education, income, cigarette use, alcohol use, body mass index, and physical activity. Age-stratified analyses (age 50 through 64 years vs 65 years and older) were also conducted. RESULTS Mean age of participants (n = 10,078) was 63.4 years; 8,518 (89.9%) were fully food secure, 1,033 (7.2%) had PVI, and 2,633 (20.1%) had SRVI. Compared with full food security, adjusting for sociodemographic confounders, those with marginal (adjusted odds ratio [aOR], 1.31; 95% CI, 0.97-1.76), low (aOR, 1.61; 95% CI, 1.17-2.23), and very low (aOR, 2.71; 95% CI, 1.75-4.20) food security had higher odds of PVI. Compared with full food security, those with marginal (aOR, 1.58; 95% CI, 1.23-2.02), low (aOR, 1.46; 95% CI, 1.11-1.92), and very low (aOR, 1.85; 95% CI, 1.41-2.41) food security had higher odds of SRVI. The associations between food insecurity and PVI were greater in magnitude in those 65 years and older compared with those age 50 through 64 years. CONCLUSIONS In this nationally representative sample of US adults 50 years and older, severe food insecurity was increasingly associated with greater prevalence of VI in a dose-response manner.

Abstract
PURPOSE To explore whether there is an association between dietary choline intake and odds of diabetic retinopathy (DR) in the US diabetic population. METHODS A cross-sectional study was conducted using the combined data of the National Health and Nutrition Examination Survey (NHANES) 2005-2008 of a complex, multistage, and probability-sampling design. Energy-adjusted choline intake was calculated separately for men and women using the residual method. Binary logistic regression adjusting for covariates was used to identify the variables associated with DR. RESULTS We included 644 male and 628 female diabetic subjects, which were equivalent to a weighted survey sample of 9,339,124 for males and 10,109,553 for females respectively. Female DR patients consumed more choline than non-DR patients (268.6 mg/d vs 250.9 mg/d; p = .046). The estimated prevalence of DR was 17.4%, 21.9%, and 29.7% across three levels of dietary choline intake in females, respectively. In multivariable logistic-regression models, the odds ratio (OR) of DR for female patients in the highest choline intake group was 2.14 (95% confidence interval [CI], 1.38-3.31; p = .001) compared with those in the lowest intake group. This association was positive but not statistically significant in males. CONCLUSION Higher intake of dietary choline is associated with increased odds of DR in females, but not in males. Further studies are warranted to investigate the direct role of choline in DR development and determine the recommended daily intake of choline for diabetic patients weighing the pros and cons of dietary choline consumption.

Abstract
Background: Emerging studies show that certain plant compounds may reduce the severity of most prevalent ocular abnormalities. The aim of this systematic review and meta-analysis was to assess the effect of dietary flavonoids on major eye disorders. Methods: Eligible studies were identified by searching PubMed, Web of Science, Scopus, and Cochrane Library databases for all articles published up to April 2021. The literature search yielded 1,134 articles, and a total of 16 studies were included in the systematic review. A meta-analysis of 11 intervention trials involving a total of 724 participants was performed. Results: Using a random-effects model, the pooled results revealed an overall significant effect of flavonoids on common ophthalmic disorders (standard mean difference = −0.39; 95% CI: −0.56, −0.21, p < 0.01). Of the subclasses of flavonoids, flavan-3-ols (standard mean difference = −0.62; 95% CI: −1.03, −0.22, p < 0.01), and anthocyanins (standard mean difference = −0.42; 95% CI: −0.63, −0.21, p < 0.01) were the only effective intervention for improving the outcomes of ocular conditions. For several of the other flavonoid subclasses, evidence on efficacy was insufficient. Conclusion: Our findings indicate that flavonoids may improve the clinical manifestations associated with ocular disorders. However, further well-constructed clinical trials are required to confirm these results and examine the effect of flavonoids on eye disorders other than those identified in this review. Systematic Review Registration: PROSPERO, identifier CRD42021247332.

Abstract
The purpose of this study was to identify circulating biomarkers of recurrent non-infectious anterior uveitis (NIAU), and to address the anti-inflammatory effects of triglyceride containing docosahexaenoic acid (DHA-TG). A prospective multicenter study was conducted in 72 participants distributed into: patients diagnosed with recurrent NIAU in the quiescence stage (uveitis group (UG); n = 36) and healthy controls (control group (CG); n = 36). Each group was randomly assigned to the oral supplementation of one pill/day (+) containing DHA-TG (n = 18) or no-pill condition (-) (n = 17) for three consecutive months. Data from demographics, risk factors, comorbidities, eye complications and therapy were recorded. Blood was collected and processed to determine pro-inflammatory biomarkers by bead-base multiplex assay. Statistical processing with multivariate statistical analysis was performed. The mean age was 50, 12 (10, 31) years. The distribution by gender was 45% males and 55% females. The mean number of uveitis episodes was 5 (2). Higher plasma expression of interleukin (IL)-6 was detected in the UG versus the CG (p = 5 × 10-5). Likewise, significantly higher plasma levels were seen for IL-1β, IL-2, INFγ (p = 10-4), and TNFα (p = 2 × 10-4) in the UG versus the CG. Significantly lower values of the above molecules were found in the +DHA-TG than in the -DHA-TG subgroups, after 3 months of follow-up, TNFα (p = 10-7) and IL-6 (p = 3 × 10-6) being those that most significantly changed. Signatures of circulating inflammatory mediators were obtained in the quiescent stage of recurrent NIAU patients. This 3-month follow-up strongly reinforces that a regular oral administration of DHA-TG reduces the inflammatory load and may potentially supply a prophylaxis-adjunctive mediator for patients at risk of uveitis vision loss.
