MIND diet lowers risk of open-angle glaucoma: the Rotterdam Study

Purpose To assess the association between the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet and the incidence of open-angle glaucoma (iOAG), as well as the association between iOAG and two other well-established diets in the Netherlands, i.e., the Mediterranean diet and Dutch dietary guidelines. Methods In the Rotterdam Study, participants were followed for iOAG since 1991, with intervals of approximately 5 years. A total of 170 participants developed iOAG during follow-up. Participants with iOAG were matched with healthy controls on age and sex in a case:control ratio of 1:5. The associations between food frequency questionnaire-derived diet adherences (baseline) and iOAG were analyzed using multivariable conditional logistic regression analyses. The associations between the diet adherences and intraocular pressure (IOP; a risk factor for OAG) were assessed using multivariable linear regression analyses. Results Greater adherence to the MIND diet was associated with a decreased iOAG risk (odds ratio [95% confidence interval]: 0.80 [0.66 to 0.96], for each 10-percent increase in adherence). Food component analyses showed that, in particular a higher intake of green leafy vegetables, berries and fish tended to be protective for iOAG. No significant associations were observed between adherence to the Mediterranean diet or Dutch dietary guidelines and iOAG. Moreover, none of the three examined diets were associated with IOP. Conclusion Adherence to the MIND diet was significantly associated with a lower incidence of OAG in contrast to adherence to the Mediterranean diet or the Dutch dietary guidelines. As this association was IOP-independent, the MIND diet may be particularly relevant for the prevention of neurodegeneration in the eye

Younger facial looks are associate with a lower likelihood of several age-related morbidities in the middle-aged to elderly

BACKGROUND: Looking older for one's chronological age is associated with a higher mortality rate. Yet it remains unclear how perceived facial age relates to morbidity and the degree to which facial ageing reflects systemic ageing of the human body. OBJECTIVES: To investigate the association between ΔPA and age-related morbidities of different organ systems, where ΔPA represents the difference between perceived age (PA) and chronological age. METHODS: We performed a cross-sectional analysis on data from the Rotterdam Study, a population-based cohort study in the Netherlands. High-resolution facial photographs of 2679 men and women aged 51.5-87.8 years of European descent were used to assess PA. PA was estimated and scored in 5-year categories using these photographs by a panel of men and women who were blinded for chronological age and medical history. A linear mixed model was used to generate the mean PAs. The difference between the mean PA and chronological age was calculated (ΔPA), where a higher (positive) ΔPA means that the person looks younger for their age and a lower (negative) ΔPA that the person looks older. ΔPA was tested as a continuous variable for association with ageing-related morbidities including cardiovascular, pulmonary, ophthalmological, neurocognitive, renal, skeletal and auditory morbidities in separate regression analyses, adjusted for age and sex (model 1) and additionally for body mass index, smoking and sun exposure (model 2). RESULTS: We observed 5-year higher ΔPA (i.e. looking younger by 5 years for one's age) to be associated with less osteoporosis [odds ratio (OR) 0.76, 95% confidence interval (CI) 0.62-0.93], less chronic obstructive pulmonary disease (OR 0.85, 95% CI 0.77-0.95), less age-related hearing loss (model 2; B = -0.76, 95% CI -1.35 to -0.17) and fewer cataracts (OR 0.84, 95% CI 0.73-0.97), but with better global cognitive functioning (g-factor; model 2; B = 0.07, 95% CI 0.04-0.10). CONCLUSIONS: PA is associated with multiple morbidities and better cognitive function, suggesting that systemic ageing and cognitive ageing are, to an extent, externally visible in the human face
