Telemedicine and ocular health in diabetes mellitus
No full textTeleretinal/teleophthalmological programs that use existing health information technology
infrastructure solutions for people with diabetes increase access to and adherence to appropriate eye care. Teleophthalmological studies indicate that the single act of patients viewing their own retinal images improves self-management behaviour and clinical outcomes. In some settings this can be done at lower cost and with improved visual outcomes compared with standard eye care. Cost-effective and sustainable teleretinal surveillance for detection of diabetic retinopathy requires a combination of an
inexpensive portable device for taking low light-level retinal images without the use of
pharmacological dilation of the pupil and a computer-assisted methodology for rapidly
detecting and diagnosing diabetic retinopathy. A more holistic telehealth-care paradigm augmented with the use of health information technology, medical devices, mobile phone and mobile health applications and software applications to improve
health-care co-ordination, self-care management and education can significantly impact a broad range of health outcomes, including prevention of diabetes-associated visual loss. This approach will require a collaborative, transformational, patient-centred health-care program that integrates data from medical record systems with remote monitoring of data and a longitudinal health record. This includes data associated with
social media applications and personal mobile health technology and should support
continuous interactions between the patient, health-care team and the patient’s social
environment. Taken together, this system will deliver contextually and temporally relevant
decision support to patients to facilitate their well-being and to reduce the risk of diabetic complications.Sven-Erik Bursell, Laima Brazionis and Alicia Jenkin

Characterizing whole diets of young children from developed countries and the association between diet and health: a systematic review
No full textLink to a related website: https://academic.oup.com/nutritionreviews/article-pdf/69/8/449/24094433/nutritionreviews69-0449.pdf, Open Access via UnpaywallEarly childhood is an important nutritional period that involves the transition from a milk-based diet to ordinary foods. A systematic review was conducted of studies that applied whole-of-diet analysis of children aged 1−5 years to examine associations between diet and nutrition, health, and development. Literature searches identified 40 articles using dietary indices, principal component analysis, or cluster analysis. Reports that applied indices (n = 23, 18 indices) were cross-sectional, and most measured diet quality or variety. Articles reporting principal component or cluster analyses (n = 17) described between two and six dietary patterns, and most identified healthy, unhealthy, and traditional patterns. In cross-sectional analyses, mixed associations were found between index or pattern scores and nutrient intake (n = 10), nutritional biomarkers (n = 1), and anthropometry (n = 10). Five reports from two birth cohorts showed healthier dietary patterns were associated with better lean mass, cognition, and behavior, but not with bone mass or body mass index at later ages. Few studies have characterized the diets of children under 5 years of age and linked diet with health. Given the limited evidence, research establishing the predictive validity of whole-of-diet methods in childhood is needed.Lisa G Smithers, Rebecca K Golley, Laima Brazionis, and John W Lync
A preference based measure of complementary feeding quality: Application to the Avon Longitudinal Study of Parents and Children
No full textThis paper presents the development of the Complementary Feeding Utility Index (CFUI), a composite index aimed to measure adherence to infant feeding guidelines. Through an axiomatic characterization this paper shows the advantages in using the CFUI are the following: it avoids the use of arbitrary cut-offs, and by converting observed diet preferences into utilities, summing the score is meaningful. In addition, as the CFUI is designed to be scored continuously, it allows the transition from intake of beneficial foods (in low quantities) and intake of detrimental foods (in high quantities) to be more subtle. The paper first describes the rationale being the development of the CFUI and then elaborates on the methodology used to develop the CFUI, including the process of selecting the components. The methodology is applied to data collected from the Avon Longitudinal Study of Parents and Children to show the advantages of the CFUI over traditional diet index approaches. Unlike traditional approaches, the distribution of the CFUI does not peak towards mean value but distributes evenly towards the tails of the distribution.Murthy N. Mittinty, Rebecca K.

Dietary patterns of infants and toddlers are associated with nutrient intakes
No full textDietary patterns are a useful summary measure of diet. Few studies have examined the nutrient profiles underpinning the dietary patterns of young children. The study aim is to determine whether dietary patterns at 6 and 15 months of age are associated with nutrient intakes at 8 and 18 months, respectively. Participants were children from the Avon Longitudinal Study of Parents and Children who had complete dietary pattern and nutrient intake data (n = 725 at 6–8 months, n = 535 at 15–18 months). The association between tertiles of dietary pattern scores and nutrient intake was examined using a non-parametric test for trend. Scores on the home-made traditional pattern (6–8 months) were positively associated with median energy intake. Each dietary pattern had different associations with energy-adjusted intakes of macro- and micro-nutrients. At both times, the discretionary pattern was positively and the ready-prepared baby foods pattern was negatively associated with sodium intake. At 6–8 months, calcium and iron intakes decreased across scores on the home-made traditional and breastfeeding patterns, but increased across the ready-prepared baby food patterns. These findings highlight that dietary patterns in infants and toddlers vary in their underlying energy and nutrient composition.Lisa G. Smithers, Rebecca K.

Dietary patterns and cardiovascular mortality in the Melbourne Collaborative Cohort Study
No full textBackground: Despite increased cardiovascular disease risk factors, migrants to Australia from Mediterranean countries have lower mortality than do native-born Australians. Dietary patterns may contribute to this. Objective: The objective was to investigate the relation between dietary patterns and mortality from cardiovascular (CVD) and ischemic heart disease (IHD) in an ethnically diverse population. Design: This was a prospective cohort study (mean follow-up: 10.4 y) of 40 653 volunteers (23 980 women) aged 40–69 y in the Melbourne Collaborative Cohort Study (1990–1994); 24% of the subjects were Mediterranean born. Results: Four dietary factors were identified from a food-frequency questionnaire with the use of principal components analysis. They explained 69% of intake variance and reflected frequent intakes of Mediterranean foods, vegetables, meat, and fresh fruit. The Mediterranean factor was inversely associated with CVD and IHD mortality in models adjusting for diabetes, waist-to-hip ratio, body mass index, and hypertension. For IHD, the hazard ratio (HR) for the highest compared with the lowest quartile of consumption was 0.59 (95% CI: 0.39, 0.89; P for trend = 0.03). Associations persisted in analyses excluding people with prior CVD (HR: 0.51; 95% CI: 0.30, 0.88; P for trend = 0.03). Vegetable and fresh fruit factors were inversely associated with CVD mortality but only among those without prior CVD. HRs (highest compared with lowest quartile) were 0.66 (95% CI: 0.48, 0.92; P for trend = 0.02) for vegetables and 0.69 (95% CI: 0.52, 0.93; P for trend = 0.04) for fresh fruit. The meat factor was not associated with CVD or IHD mortality. Conclusion: Our findings suggest that frequent consumption of traditional Mediterranean foods is associated with reduced cardiovascular mortality after controlling for important risk factors and country of birth.Linton R Harriss, Dallas R English, John Powles, Graham G Giles, Andrew M Tonkin, Allison M Hodge, Laima Brazionis, and Kerin O’De
An index measuring adherence to complementary feeding guidelines has convergent validity as a measure of infant diet quality
No full textThe complementary feeding period is an important stage of child development. The study aim was to develop an index reflecting the degree of adherence to complementary feeding guidelines, evaluate its convergent validity, and explore associations with socio-demographic factors and dietary pattern scores in childhood. Data were analyzed from the Avon Longitudinal Study of Parents and Children (n = 6065) using parent-completed dietary questionnaires at 6 mo of age, sociodemographic information, and dietary patterns derived by principal component analysis at age 3 y. The Complementary Feeding Utility Index (CFUI) consists of 14 components: breastfeeding duration, feeding to appetite, timing of introduction to solids, exposure to iron-rich cereals, fruit and vegetable intake, exposure to high-fat/-salt/-sugar foods including sugary drinks, food texture, and meal/snack frequency. Regression analyses were undertaken to investigate associations between index scores, socio-demographic factors, food and nutrient intakes, and dietary pattern scores at age 3 y. Milk and food intake at 6 mo and nutrient intake at 8 mo of age varied across quintiles of index score in largely the expected directions. Associations were found among index score, maternal age, education, social class, maternal smoking history, and prepregnancy BMI. After adjustment for socio-demographic factors, the index score was associated with “processed“ [b = 20.234 (95% CI = 20.260, –0.209)] and “healthy” [b = 0.185 (95% CI = 0.155, 0.215)] dietary pattern scores at age 3 y. The CFUI is able to discriminate across food intake, nutrient intake, and socio-demographic factors and is associated with later dietary patterns.Rebecca K. Golley, Lisa G. Smithers, Murthy N.
