The Impact

Intake of vitamins A, C, and E was evaluated and age and time trends were assessed on the basis of 3-day weighed dietary records (n = 5121) of 2- to 18-year old boys (n = 417) and girls (n = 425) enrolled in the DONALD Study (Dortmund Nutritional and Anthropometric Longitudinally Designed Study) 1986–2001. Intake of vitamin A remains stable over time, intake of vitamin C increases linearly, and intake of vitamin E follows a nonlinear trend. Age trends of vitamins A and C (per MJ) were nonlinear with a minimum at the beginning adolescence, while intake of vitamin E (per MJ) increased linearly. Girls had higher nutrient densities but lower intakes expressed as percent of reference values. Fortified food in total had a higher impact on time trends of nutrient intake than other single food groups defined here. Our results point to the impact of the food industry on long-term nutrient intake, but also underline the necessity of nutrition education even in young age groups to improve vitamin intake.

Background: According to recent figures, Amsterdam is the municipality with the highest absolute number of suicides and the second highest suicide rate in the Netherlands. Aims: The aim of the study was to identify time trends and demographic differences in the occurrence of nonfatal suicide attempts versus suicides. Methods: We used registrations of forensic physicians and ambulance services of the Municipal Health Service of Amsterdam to study 1,004 suicides and 6,166 nonfatal attempts occurring in Amsterdam over the period 1996–2005. Results: The number of nonfatal attempts declined from 1996 to 2005, but the number of completed suicides remained relatively stable. Although case fatality was strongly associated with method used, we also found higher case fatalities for men and older people independent of method. Conclusions: The case fatality results suggest differences in motive among different demographic groups: possibly the wish to die is stronger among men and elderly. This finding had implications for the success to be expected from different preventive measures.
