PURPOSE Anthocyanin intake estimations in large cohorts include almost exclusively adults. For the purpose of early dietary prevention, however, it is of great interest to estimate anthocyanin intake of children and adolescents. METHODS Anthocyanidin content values from the USDA Database (excluding the values for bananas and nuts) were assigned to foods(More)
The authors prospectively examined whether change in dietary glycemic index (GI), glycemic load (GL), fiber intake, or whole-grain intake during puberty is associated with concurrent change in percentage of body fat (%BF) or body mass index (BMI; weight (kg)/height)(2). Linear mixed-effects regression analyses were performed in 215 participants from the(More)
PURPOSE Anthocyanins, a colourful group of flavonoids in many fruits and vegetables, are proposed to provide positive impact on human health. However, intake estimations have almost exclusively been conducted in adult populations. As infants and toddlers are a promising age group for health promotion, we examined their anthocyanin intake (as(More)
Background/Objectives:Considering the large number of children worldwide attending all-day schools, information on the effects of lunch on short-term cognitive performance is of public health relevance. However, only adult studies investigated this issue yet. Therefore, this study examined the impact of skipping lunch vs having lunch on children’s cognitive(More)
Given that commercial complementary food (CF) can contain high levels of added sugar, a high consumption may predispose to a preference for sweet taste later in life. This study examined cross-sectional associations between commercial CF consumption and added sugar intake in infancy as well as its prospective relation to added sugar intake in pre-school and(More)
Objectives:To examine whether maximal velocities of weight, height and fat mass during potentially critical periods of growth were associated with body composition in young adulthood.Subjects/methods:Analyses were performed on 277 female and 271 male participants of the DOrtmund Nutritional and Anthropometric Longitudinally Designed (DONALD) study with(More)
There is evidence that a diet rich in plant foods is protective against cardiovascular disease and cancer, partly attributable to secondary plant metabolites such as anthocyanins, a colourful group of flavonoids. As at present children and adolescents do not consume the recommended amounts of fruits and vegetables, one possible way of increasing intake, and(More)
PURPOSE To describe age and time trends in eating occasion frequency (EOF), meal frequency (MF), snack frequency (SF) and duration of nightly fasting (DNF) in German children and adolescents. METHODS 9757 3-day dietary records of 1246 3-18-year-old participants of the open DONALD cohort study, collected 1985-2014, were analyzed for age and time trends(More)
Exclusive breastfeeding is recommended for infants during the first 6 months of life. The aim of this analysis was to examine time trends in breastfeeding between 1990 and 2013 in Germany using data from the DONALD (Dortmund Nutritional and Anthropometric Longitudinally Designed) Study. Although partial breastfeeding was observed to constantly increase over(More)
