|Erasmus University Medical Center
I am a nutritionist and postdoctoral researcher at ErasmusAGE, department of epidemiology, Erasmus MC, Rotterdam, the Netherlands. I hold a BSc degree in Nutrition and Health and a MSc degree in Nutritional Physiology, both from the Wageningen University. My research mainly focuses on investigating the role of nutrition and physical activity on ageing, with a particular interest in frailty, sarcopenia and musculoskeletal health. For my studies I use the data from the Rotterdam Study, on ongoing population based cohort among almost 15,000 older adults and older people that have been followed for nearly 25 years. My interests include dietary patterns, protein intake, anti-oxidant intake, body composition, trajectories of health and healthy ageing. So far I have published 25 international scientific papers and 1 book chapter and currently lead a research line including 4 PhD students and 7 Master students.

Contributions to Science
Frailty and ageing in people with intellectual disabilities: For the first time a frailty index was applied to a large group of older adults with intellectual disabilities. We found that older people with intellectual disabilities are earlier and more severely frail than older people without an intellectual disability. Frailty was associated to severe health outcomes. For example we showed that a high frailty was related to a higher risk for mortality, decline in dependence, decline in mobility and increased care use.

From 2015 onwards I focus on the effect of nutrition and physical activity on age-related outcomes in the general population and how socio-economic status might influence this association. We have found that a high education is associated with a higher dietary quality and to a larger likelihood to beneficially change dietary quality over time. Specifically, we found that people with a high education were more likely to adapt their diet as a responds to new dietary guidelines (i.e higher intake of fish and lower intake of trans fatty acids after this was recommended by the Dutch dietary quidelines). Furthermore, we found that physical activity and dietary intake can beneficially effect frailty, the risk for cardiovascular disease, bone mineral density and mortality.
