[The DONALD cohort. An updated overview on 25 years of research based on the Dortmund Nutritional and Anthropometric Longitudinally Designed study].
The DONALD study has been conducted in Dortmund, Germany since 1985 to examine the complex relations between nutritional intake, metabolism and growth from infancy to adulthood. Every year, approximately 40 infants are newly recruited into the open cohort study. Examinations conducted at ages 3, 6, 9, 12, 18, 24 months and then annually until young adulthood, comprise anthropometry, a 3 day weighed dietary record, a 24 h urine sample (from age 3-4 years onwards), medical examinations and parental interviews. Since 2005, participants are invited for follow-up visits during adulthood (including fasting blood samples). Approximately 1,400 children have been recruited into the study up to 2010. Recent findings revealed e.g. (i) the relevance of early life factors for subsequent development of body composition and puberty timing, (ii) the relation between pubertal hormonal status and puberty onset, (iii) age and time trends in iodine status and modern dietary habits and (iv) potential furan and benzol exposition by commercial weaning foods. Future analyses will provide insight into the extent to which health in young adulthood is receptive to diet, anthropometric pattern and hormonal status in distinct potentially critical periods during childhood.
