Abstract Background Diet is a key risk factor for chronic disease, and an increasing concern among older adults. We aim to examine the changes in dietary patterns using principal component analysis and a diet quality index among older adults and examine the predictors of dietary change over a 4 year period. Methods Data was obtained via a postal survey in a prospective cohort, the Wellbeing Eating and Exercise for a Long Life (WELL) study. Australian adults aged 55 years and over (n = 1005 men and n = 1106 women) completed a food frequency at three time points and provided self-reported personal characteristics. Principal component analysis was used to assess dietary patterns and diet quality was assessed using the 2013 Revised Dietary Guideline Index. The relationships between predictors and change in dietary patterns were assessed by multiple linear regression. Results Two dietary patterns were consistently identified in men and women at three time points over 4 years. One was characterised by vegetables, fruit and white meat, and the other was characterised by red and processed meat and processed foods. Reduced consumption of key food groups within the principal component analysis-determined dietary patterns was observed. An increase in diet quality over 4 years was observed in men only. Reported higher education levels and favourable lifestyle characteristics, including not smoking and physical activity, at baseline predicted an increase in healthier dietary patterns over 4 years. Conclusions There was stability in the main dietary patterns identified over time, however participants reported an overall decrease in the frequency of consumption of key food groups. Compliance with the Australian Dietary Guidelines remained poor and therefore targeting this population in nutritional initiatives is important. Design of nutrition promotion for older adults need to consider those with lower socioeconomic status, as having a lower level of education was a predictor of poorer dietary patterns. It is important to consider how nutrition behaviours can be targeted alongside other lifestyle behaviours, such as smoking and inadequate physical activity to improve health.

Abstract Objective: To characterize the dietary pattern of nursing professionals at a public hospital in Rio de Janeiro, RJ, Brazil. Method: A sectional study with nursing professionals (nurses, technicians and nursing assistants). Two 24-hour food recall records were applied, totaling 459 foods, being reduced to 24 food groups. Food patterns were identified using the Principal Component Analysis technique, followed by orthogonal varimax rotation. A Scree Plot graph indicated three factors to be extracted and loads > +0.30 were adopted to define dietary patterns. Results: A total of 309 professionals participated. The sample consisted of 85.8% of female individuals. The patterns were named “traditional” which included rice (0.747), beans (0.702) and meat (0.713); “healthy”: vegetables (0.444), greens (0.450), fruits (0.459), bananas and oranges (0.379), and “snacks”: sugar (0.661), bread (0.471), cakes and cookies (0.334), non-alcoholic drinks (0.727). Conclusion: The results highlight the “traditional” food pattern of Brazilian food consumption based on the combination of rice, beans and meat. Future studies may investigate the effect of dietary patterns on health outcomes among nursing workers.

Objective: To determine the association between measures of overall diet quality (dietary indices/patterns) and risk of multiple sclerosis (MS). Methods: Over 185,000 women in the Nurses’ Health Study (NHS) and Nurses’ Health Study II (NHSII) completed semiquantitative food frequency questionnaires every 4 years. There were 480 MS incident cases. Diet quality was assessed using the Alternative Healthy Eating Index-2010 (AHEI-2010), Alternate Mediterranean Diet (aMED) index, and Dietary Approaches to Stop Hypertension (DASH) index. Principal component analysis was used to determine major dietary patterns. We calculated the hazard ratio (HR) of MS with Cox multivariate models adjusted for age, latitude of residence at age 15, body mass index at age 18, supplemental vitamin D intake, and cigarette smoking. Results: None of the dietary indices, AHEI-2010, aMED, or DASH, at baseline was statistically significantly related to the risk of MS. The principal component analysis identified “Western” and “prudent” dietary patterns, neither of which was associated with MS risk (HR, top vs bottom quintile: Western, 0.81 ( p = 0.31) and prudent, 0.96 ( p = 0.94)). When the analysis was repeated using cumulative average dietary pattern scores, the results were unchanged. Conclusion: There was no evidence of an association between overall diet quality and risk of developing MS among women.

Background: Diet quality is a major risk factor for morbidity and mortality, but few studies have examined the relationship between dietary patterns and the risk of cardiovascular disease (CVD) and mortality in older adults. We examined prospective associations between dietary patterns defined using principal component analysis and the risk of CVD and all-cause mortality in older British men. Methods: 3226 men aged 60-79 years from the British Regional Heart Study, free from CVD at baseline, were followed-up for 11 years. Baseline food frequency questionnaire data were used to generate dietary intake data on 34 food groups. Principal component analysis identified dietary patterns which were then categorised according to quartiles of adherence. Cox proportional hazards regression examined associations between dietary patterns and risk of all-cause mortality, CVD mortality, CVD events and coronary heart disease (CHD) events, adjusting for confounders. Results: Principal component analysis identified three interpretable dietary patterns, which explained 20.8% of the total variance. An ‘unhealthy’ dietary pattern explained the greatest single proportion of the variance (7.9%) and was characterised by consumption of red meat, meat products, white bread, fried potato and eggs. A ‘healthy’ dietary pattern was characterised by consumption of poultry, fish, fruit, vegetables, legumes, pasta, rice, wholemeal bread, eggs and olive oil and explained 7.1% of the variance. Finally, a ‘sweet’ dietary pattern was characterised by consumption of biscuits, puddings, chocolate, sweets, sweet spreads and breakfast cereal and explained 5.8% of the variance. There were 899 deaths, 316 CVD deaths, 569 CVD events and 301 CHD events during follow-up. An ‘unhealthy’ dietary pattern was associated with a graded increase in risk of all-cause mortality, after adjustment for sociodemographic, behavioural and cardiovascular risk factors (highest vs. lowest quartile; HR: 1.44, 95% CI: 1.13-1.84, p-trend = 0.007). No significant associations were seen between the risk of all-cause mortality and the ‘healthy’ diet (highest vs. lowest quartile; HR: 0.83, 95% CI: 0.66-1.04, p-trend = 0.28) or the ‘sweet’ diet (highest vs. lowest quartile; HR: 1.00, 95% CI: 0.77-1.29, p-trend = 0.71). None of the dietary patterns were significantly associated with cardiovascular outcomes (CVD mortality, CVD events or CHD events). Conclusions: Dietary patterns are an important risk factor for all-cause mortality in the elderly. Older adults should avoid a high consumption of components of an ‘unhealthy’ dietary pattern to reduce the risk of all-cause mortality.

Εισαγωγή: Η εμμηνόπαυση θέτει τις γυναίκες σε υψηλό κίνδυνο εμφάνισης χρόνιων νοσημάτων, όπως παχυσαρκία και καρδιαγγειακά νοσήματα. Παρόλα αυτά, εξαιρετικά λίγες μελέτες έχουν διεξαχθεί σε πληθυσμό μετεμμηνοπαυσιακών γυναικών με σκοπό την εκτίμηση της επίδρασης της διατροφής σε δομικούς και λειτουργικούς δείκτες αγγειακής λειτουργίας. Σκοπός: Κύριο σκοπό της παρούσας διατριβής αποτέλεσε η αξιολόγηση των διατροφικών συνηθειών μιας ομάδας υγιών μετεμμηνοπαυσιακών γυναικών. Παράλληλα, η διερεύνηση της υπάρχουσας σχέσης μεταξύ του Μεσογειακού τρόπου ζωής και της έκβασης δομικών και λειτουργικών αρτηριακών δεικτών σε υπο-ομάδα γυναικών αποτέλεσε επιπρόσθετο στόχο. Μεθοδολογία: Δείγμα της μελέτης αποτέλεσαν 638 γυναίκες που προσήλθαν στο εξωτερικό ιατρείο Κλιμακτηρίου και Εμμηνόπαυσης του Αρεταίειου Νοσοκομείου Αθηνών. Κριτήρια ένταξης ήταν η ύπαρξη εμμηνόπαυσης, δηλαδή απουσία έμμηνου ρύσεως για τουλάχιστον 12 συνεχόμενους μήνες και επίπεδα FSH >25 mIU/mL και οιστραδιόλης <50 pg/mL. Καταγράφηκαν τα δημογραφικά χαρακτηριστικά και το ιατρικό και γυναικολογικό ιστορικό των γυναικών. Επίσης, πραγματοποιήθηκε αξιολόγηση της σωματικής δραστηριότητας μέσω του International Physical Activity Questionnaire και διατροφική αξιολόγηση μέσω έγκυρου ερωτηματολογίου συχνότητας κατανάλωσης τροφίμων και υπολογίστηκε η προσκόλληση στη μεσογειακή δίαιτα μέσω του δείκτη MedDietScore. Τέλος, μετρήθηκαν ανθρωπομετρικά χαρακτηριστικά, πραγματοποιήθηκε κλινική εξέταση και αξιολογήθηκαν βιοχημικοί και ορμονικοί δείκτες. Αποτελέσματα: Η μέση ηλικία του δείγματος ήταν 57,7 ±7,6 έτη, ενώ ο ΔΜΣ ήταν 27,9 ± 5,0 kg/m2. Η μέση προσκόλληση στη μεσογειακή δίαιτα των συμμετεχουσών, σύμφωνα με το MedDietScore ήταν 36,1 ±4,7. Από την εφαρμογή πολλαπλής λογιστικής παλινδρόμησης παρατηρήθηκε ότι η Μεσογειακή δίαιτα σχετίστηκε αρνητικά με το ΔΜΣ και την περιφέρεια μέσης των γυναικών του δείγματος, μετά από προσαρμογή για συγχυτικούς παράγοντες. Ειδικότερα, οι γυναίκες υψηλής και μέτριας προσκόλλησης στη Μεσογειακή δίαιτα είχαν σημαντικά χαμηλότερους δείκτες παχυσαρκίας, υψηλότερο επίπεδο φυσικής δραστηριότητας και υψηλότερο μορφωτικό επίπεδο, σε σύγκριση με τις γυναίκες χαμηλής προσκόλλησης στο συγκεκριμένο διαιτητικό πρότυπο. Παράλληλα, μετά την εφαρμογή της Principal Component Analysis σε υπο-ομάδα 481 γυναικών του δείγματος δημιουργήθηκαν 8 διατροφικά πρότυπα, εκ των οποίων ένα διατροφικό πρότυπο πλούσιο σε διαιτητικές ίνες και σύνθετους υδατάνθρακες σχετίστηκε αρνητικά με το ΔΜΣ και την περιφέρεια μέσης των γυναικών, ενώ ένα ανθυγιεινό διατροφικό πρότυπο σχετίστηκε θετικά με το ΔΜΣ και την περιφέρεια μέσης των γυναικών, μετά την προσαρμογή για συγχυτικούς παράγοντες. Αναφορικά με την αγγειακή λειτουργία, παρατηρήθηκε σημαντική αρνητική συσχέτιση μεταξύ της ταχύτητας σφυγμικού κύματος αρτηρίας και της κατανάλωσης ροφημάτων καφέ/τσαγιού (r=-0.233, p<0.001). Ακόμη, παρατηρήθηκε θετική συσχέτιση μεταξύ του πάχους κοινής καρωτίδας και της κατανάλωσης επεξεργασμένων δημητριακών (r=0.116, p=0.04). Έπειτα από πολλαπλή γραμμική παλλινδρόμηση, η κατανάλωση ξηρών καρπών και ροφημάτων καφέ/τσαγιού σχετίστηκαν σημαντικά αρνητικά με το πάχος κοινής καρωτίδας (b-coefficient=-0.018, p=0.05) και την ταχύτητα σφυγμικού κύματος (b-coefficient= -0.327, p=0.002), αντίστοιχα. Ενώ, η κατανάλωση πατάτας σχετίστηκε σημαντικά θετικά με το πάχος κοινής καρωτίδας (b-coefficient=0.106, p<0.001). Συμπεράσματα: Η ύπαρξη διαφορετικών διατροφικών προτύπων σχετίστηκε, θετικά ή αρνητικά, με το σωματικό βάρος και την περιφέρεια μέσης στις μετεμμηνοπαυσιακές γυναίκες. Ειδικότερα, παρατηρήθηκε προστατευτική δράση της Μεσογειακής δίαιτας στους δείκτες παχυσαρκίας και η ύπαρξη σημαντικής συσχέτισης μεταξύ ορισμένων διατροφικών συνηθειών και δεικτών αγγειακής λειτουργίας

Chamber Size

When exploring biological determinants of spontaneous physical activity (SPA), it is critical to consider whether methodological factors differentially affect rodents and the measured SPA. We determined whether acclimation time, sensory stimulation, vendor, or chamber size affected measures in rodents with varying propensity for SPA. We used principal component analysis to determine which SPA components (ambulatory and vertical counts, time in SPA, and distance traveled) best described the variability in SPA measurements. We compared radiotelemetry and infrared photobeams used to measure SPA and exploratory activity. Acclimation time, sensory stimulation, vendor, and chamber size independently influenced SPA, and the effect was moderated by the propensity for SPA. A 24-h acclimation period prior to SPA measurement was sufficient for habituation. Principal component analysis showed that ambulatory and vertical measurements of SPA describe different dimensions of the rodent's SPA behavior. Smaller testing chambers and a sensory attenuation cubicle around the chamber reduced SPA. SPA varies between rodents purchased from different vendors. Radiotelemetry and infrared photobeams differ in their sensitivity to detect phenotypic differences in SPA and exploratory activity. These data highlight methodological considerations in rodent SPA measurement and a need to standardize SPA methodology.

Abstract Metabolic syndrome is common in older adults and may be modified by the diet. The aim of this study was to examine associations between a posteriori dietary patterns and metabolic syndrome in an older New Zealand population. The REACH study (Researching Eating, Activity, and Cognitive Health) included 366 participants (65-74 years, 36% male) living independently in Auckland, New Zealand. Dietary data were collected using a 109-item food frequency questionnaire with demonstrated validity and reproducibility for assessing dietary patterns using principal component analysis. Metabolic syndrome was defined by the National Cholesterol Education Program Adult Treatment Panel III. Associations between dietary patterns and metabolic syndrome, adjusted for age, sex, index of multiple deprivation, physical activity, and energy intake were analysed using logistic regression analysis. Three dietary patterns explained 18% of dietary intake variation – ‘Mediterranean style’ (salad/leafy cruciferous/other vegetables, avocados/olives, alliums, nuts/seeds, shellfish and white/oily fish, berries), ‘prudent’ (dried/fresh/frozen legumes, soy-based foods, whole grains, carrots), and ‘Western’ (processed meat/fish, sauces/condiments, cakes/biscuits/puddings, meat pies/hot chips). No associations were seen between ‘Mediterranean style’ [OR=0.75 (95% CI 0.53, 1.06), P=0.11] or ‘prudent’ [OR=1.17 (95% CI 0.83, 1.59), P=0.35] patterns and metabolic syndrome after co-variate adjustment. The ‘Western’ pattern was positively associated with metabolic syndrome [OR=1.67 (95% CI 1.08, 2.63), P=0.02]. There was also a small association between an index of multiple deprivation [OR=1.04 (95% CI 1.02, 1.06), P<0.001] and metabolic syndrome. This cross-sectional study provides further support for a Western dietary pattern being a risk factor for metabolic syndrome in an older population.
