Comparison of estimated energy intake in children using a Web-based Dietary Assessment Software with accelerometer-estimated energy expenditure in children

Background: The OPUS (Optimal well-being, development and health for Danish children through a healthy New Nordic Diet) project carried out a school meal study to assess the impact of a New Nordic Diet (NND). The random controlled trial involved 834 children aged 8–11 in nine local authority schools in Denmark. Dietary assessment was carried out using a program known as WebDASC (Web-based Dietary Assessment Software for Children) to collect data from the children. Objective: To compare the energy intake (EI) of schoolchildren aged 8–11 estimated using the WebDASC system against the total energy expenditure (TEE) as derived from accelerometers worn by the children during the same period. A second objective was to evaluate the WebDASC's usability. Design: Eighty-one schoolchildren took part in what was the pilot study for the OPUS project, and they recorded their total diet using WebDASC and wore an accelerometer for two periods of seven consecutive days: at baseline, when they ate their usual packed lunches and at intervention when they were served the NND. EI was estimated using WebDASC, and TEE was calculated from accelerometer-derived activity energy expenditure, basal metabolic rate, and diet-induced thermogenesis. WebDASC's usability was assessed using a questionnaire. Parents could help their children record their diet and answer the questionnaire. Results: Evaluated against TEE as derived from the accelerometers worn at the same time, the WebDASC performed just as well as other traditional methods of collecting dietary data and proved both effective and acceptable with children aged 8–11, even with perhaps less familiar foods of the NND. Conclusions: WebDASC is a useful method that provided a reasonably accurate measure of EI at group level when compared to TEE derived from accelerometer-determined physical activity in children. WebDASC will benefit future research in this area

What do clinicians want? Interest in integrative health services at a North Carolina academic medical center

BACKGROUND: Use of complementary medicine is common, consumer driven and usually outpatient focused. We wished to determine interest among the medical staff at a North Carolina academic medical center in integrating diverse therapies and services into comprehensive care. METHODS: We conducted a cross sectional on-line survey of physicians, nurse practitioners and physician assistants at a tertiary care medical center in 2006. The survey contained questions on referrals and recommendations in the past year and interest in therapies or services if they were to be provided at the medical center in the future. RESULTS: Responses were received from 173 clinicians in 26 different departments, programs and centers. There was strong interest in offering several specific therapies: therapeutic exercise (77%), expert consultation about herbs and dietary supplements (69%), and massage (66%); there was even stronger interest in offering comprehensive treatment programs such as multidisciplinary pain management (84%), comprehensive nutritional assessment and advice (84%), obesity/healthy lifestyle promotion (80%), fit for life (exercise and lifestyle program, 76%), diabetes healthy lifestyle promotion (73%); and comprehensive psychological services for stress management, including hypnosis and biofeedback (73%). CONCLUSION: There is strong interest among medical staff at an academic health center in comprehensive, integrated services for pain, obesity, and diabetes and in specific services in fitness, nutrition and stress management. Future studies will need to assess the cost-effectiveness of such services, as well as their financial sustainability and impact on patient satisfaction, health and quality of life

Trends in added sugar intake and food sources in a cohort of older Australians: 15 years of follow-up from the Blue Mountains Eye Study

BACKGROUND: The trend of added sugar (AS) intake has not been investigated in the Australian population, including in older adults. The present study aimed to assess trends and food sources of AS intake among a cohort of older Australians during 15 years of follow-up. METHODS: Dietary data from participants of the Blue Mountains Eye Study (1264 men and 1614 women), aged ≥49 years at baseline, were collected. Dietary intakes were assessed at 5-yearly intervals (1992-94 to 2007-09) using a 145-item food frequency questionnaire (FFQ). AS content of FFQ food items was estimated using a stepwise systematic method. Trends for AS intake between baseline and the three follow-up periods were assessed using linear mixed modelling. RESULTS: In men, the mean (SEM) percentage of energy provided by AS intake (EAS%) declined from 10.4% (0.1%) at baseline to 9.4% (0.2%) at 15-year follow-up (Ptrend = 0.028). Women's mean (SEM) EAS% intake at baseline and 15-year follow-up was 9.2% (0.1%) and 8.8% (0.2%), respectively (Ptrend = 0.550). EAS% intake of men was significantly higher than that of women for 10 years (P < 0.05). Sugar products (table sugar, syrup, jam and honey) were the major sources of AS at all-time points and contributed to more than 40% and 35% of AS intake in men and women, respectively. Intake of sugar products decreased in men during follow-up (Ptrend < 0.001). CONCLUSIONS: An overall downward trend was observed in AS intake in both genders, however, was only significant for men during 15 years of follow-up. Table sugar and sugar-containing spreads represent the major source of AS in this cohort of older Australians

Added sugar intake that exceeds current recommendations is associated with nutrient dilution in older Australians

OBJECTIVES: A nutrient dilution effect of diets high in added sugar has been reported in some older populations, but the evidence is inconsistent. The aim of this study was to investigate the association between added sugar intakes (according to recommended guidelines) and nutrient intake, food consumption, and body mass index (BMI). METHODS: A cross-sectional analysis of data collected between 2007 and 2009 from participants of the Blue Mountains Eye study 4 was performed (n = 879). Dietary intake was assessed using a semiquantitative food frequency questionnaire. Added sugar content of foods was determined by applying a systematic step-wise method. BMI was calculated from measured weight and height. Food and nutrient intakes and BMI were assessed according to categories of percentage energy from added sugar (EAS% 10%) using analysis of covariance for multivariate analysis. RESULTS: Micronutrient intake including retinol equivalents, vitamins B6, B12, C, E, and D, and minerals including calcium, iron, and magnesium showed a significant inverse association with EAS% intakes (Ptrend < 0.05). In people with the lowest intake of added sugars (<5% energy) intake of alcohol, fruits, and vegetables were higher and intake of sugar sweetened beverages was lower compared to other participants (all Ptrend < 0.001). BMI was similar between the three EAS% categories. CONCLUSIONS: Energy intake from added sugar greater than the recommended level of 10% is associated with lower micronutrient intakes, indicating micronutrient dilution. Conversely, added sugar intakes <5% of energy intake are associated with higher micronutrient intakes.
