“…Although some epidemiological investigations have shown a significant increase in the sale of ultraprocessed products, which between 2000 and 2013 increased by 43.7% worldwide [23,24], the traditional pattern was the most representative of our population. It includes food items similar to those studies conducted by Gutiérrez-Pliego et al [3] and Vilela et al [6], from Spain and Brazil, respectively, who named them as prudent, and McEvoy et al [25], who investigated diet patterns in several European countries and named them as healthy.…”

A B S T R A C T ObjectiveTo examine the relationship between dietary patterns and abdominal adiposity among adults living in the urban area of Viçosa, Minas Gerais, Brazil. MethodsA population-based, cross-sectional study of 959 adults of both sexes. Information on sociodemographic characteristics and dietary intake was collected through questionnaires. Abdominal adiposity was evaluated using waist circumference and the anthropometric indices waist-to-hip ratio and waist-to-height ratio. Food patterns were identified by factor analysis. Poisson regression was used for multivariate analysis. ResultsAbdominal adiposity was identified by waist circumference in 59.06% (95%CI=52.77-65.08) of the sample, by waist-to-hip ratio in 54.65% (95%CI=47.92-61.21), and by waist-to-height ratio in 9% (95%CI=54.61-69.03). Two dietary patterns, named as traditional Brazilian and bar, were identified in the sample, but only the latter was statistically associated with abdominal adiposity determined by the three parameters. ConclusionThe study identified two eating patterns in the population, a healthy and an unhealthy pattern, the latter being associated with greater odds of abdominal adiposity. Thus, it is important to take measures to reverse this trend.

“…In addition, one trained researcher used a validated measurement and analysis protocol to objectively measure retinal vessel caliber as employed in previous studies [10][11][12][13][14]21]. Several potential limitations of this study should be mentioned.…”

“…These studies have reported inverse relationships between retinal vessel abnormalities and some dietary constituents such as dietary fibre [18], fish [19] and dairy intake [20]. However, adherence to a healthy or unhealthy derived dietary pattern was not found to be related to retinal vessel caliber measurement in European older adults [21]. To our knowledge, there are no published intervention studies examining the effect of dietary constituents on retinal vessel diameter.…”

“…Retinal photography was performed by a trained researcher using a Topcon TRC 50 EX (Topcon, Tokyo, Japan) digital camera according to a standardized protocol [21]. A color stereoscopic fundus image of visual field one (centered on the optic disc); using a field of 35° at a flash setting of 50mW was captured for each eye after dilation.…”

“…A color stereoscopic fundus image of visual field one (centered on the optic disc); using a field of 35° at a flash setting of 50mW was captured for each eye after dilation. One trained researcher measured the internal retinal vessel diameters from the obtained right eye fundus image using a validated semi-automated software program and measurement protocol (IVAN, Wisconsin, USA) as used in previous studies [10][11][12][13][14]21]. In brief, all retinal vessels > 25 µm coursing through a specified area (0.5-1.0 disc diameter surrounding the optic disc zone) were tracked by the software using microdensitometry, and were then identified as either arterioles or venules by the researcher.…”

BackgroundRetinal vessel abnormalities are associated with cardiovascular disease risk. Widening of retinal venules is associated with increased risk of stroke while narrowing of retinal arterioles independently predicts incident hypertension, coronary heart disease and diabetes. Dietary factors are known to play an important role in cardiovascular health. However, few studies have examined the association between dietary patterns (DPs) and retinal microvascular health.ObjectiveTo examine the association between ‘a posteriori’- derived DPs and retinal vascular caliber (RVC) in older women with a restricted lifestyle.MethodsThis was a cross-sectional study of 1233 participants (mean age: 76.3 years) from the Irish Nun Eye Study (INES). Computer-assisted software was used to measure RVC from digital eye images using standardized protocols. Dietary intake was assessed using a food frequency questionnaire (FFQ). DP analysis was performed using principal component analysis from completed FFQs. Regression models were used to assess associations between DPs and retinal vessel diameters, adjusting for age, body mass index, refraction, hypertension, diabetes mellitus, ischemic heart disease, cerebrovascular accident and fellow eye RVC.ResultsTwo DPs were identified: a ‘healthy’ pattern with high factor loadings for fruit, vegetables, wholegrains and oily fish and an ‘unhealthy’ pattern with high factor loadings for sugar and sweets, chips, high fat dairy products and French fries. Adjusted linear regression analysis revealed that those who adhered most closely to the unhealthy DP had wider central retinal venular equivalent (CRVE) (p=0.03) and narrower central retinal arteriolar equivalent (CRAE) (p=0.01) compared to the least unhealthy DP. No independent relationship was observed between the healthy DP and RVC.ConclusionIn this cohort of older women with a restricted lifestyle, an unhealthy DP was independently associated with an unfavorable retinal profile, namely a widening of retinal venules and narrowing of retinal arterioles.
