What We Do

We investigate various aspects, including nutrition, sleep, and physical activity.

Sarphati Cohort

‘To ensure all children in Amsterdam grow up healthy, we follow the development of children from the first years until they are 18 with the Sarphati Cohort. The collected data aims to provide answers on how we can best support parents, professionals, and policymakers in promoting the healthy growth of children. We investigate aspects such as nutrition, sleep, and physical activity. This helps us gain more insight, for example, into the influence of nutrition in the early years on the development of overweight and obesity. We strive for all parents in Amsterdam to be familiar with the health study and participate, ensuring that the research population is a good reflection of Amsterdam’s society.’

– Arnoud Verhoeff, Director of Sarphati Amsterdam.

Sarphati Cohort: Research on growth and development

Within the Sarphati Cohort, research is conducted on the growth and development of Amsterdam children aged 0 to 18 years. These children receive care from Youth Health Care (JGZ) at GGD Amsterdam and the Amsterdam Health Centers Foundation (SAG) within the Parent and Child Teams (OKTs).
During consultations at the OKTs, Youth Health Care (JGZ) records data on the health and development of children until they are 18 years old.

The best possible care

These data are recorded to provide the child with the best possible care. To conduct research, we explicitly ask parents for permission to use certain data anonymously for the Sarphati Cohort. With this research, we aim to gain insight into the causes of health problems such as diabetes, obesity, and cardiovascular diseases.

How do we handle your and your child's data?

We use a portion of the data from Youth Health Care (JGZ) for research, but only after you have given consent. During consultations, JGZ collects data on your child’s health and development, such as movement, sleep, nutrition, motor development, and growth. This data is anonymized with a code number for research.

We ensure carefulness and privacy

Researchers never see personal data of you or your child, and JGZ does not have access to the completed questionnaires. The Sarphati Cohort health study manages the data, with only the code number being visible. This number is removed before researchers gain access, ensuring that the data of you and your child(ren) are not traceable.

Upon registration, we ask for your email address to send questionnaires and research information, sometimes also by mail to the JGZ-registered address.

Who uses the data?

The data is used by researchers from Sarphati Amsterdam, including epidemiologists, sociologists, nutritionists, educators, sleep scientists, movement scientists, and physician-researchers. All researchers are affiliated with GGD Amsterdam and one of the knowledge institutions. These include Amsterdam University Medical Center (Amsterdam UMC, locations AMC and VUmc), Vrije Universiteit (VU), University of Amsterdam (UvA), and the Amsterdam University of Applied Sciences (HvA).
