Here for the Long Haul

If you ever stop by our table at a community event, one of the things that you will hear us talk about repeatedly is how big and how long the National Children’s Study (NCS) is. The NCS is simply the largest and longest study of women and children ever to be conducted in the United States. We have never had a study this big, that lasts this long, or that asks this many questions about mothers’ and children’s health. Studying so many children and pregnant women before, during and after their pregnancy for 21 years may help us answer questions about pregnancy and children’s health.

Why is such a long-term study needed? 

Scientists call long-term studies like the NCS “longitudinal.” Longitudinal studies are generally big undertakings, requiring large numbers of study participants and use of extensive resources for their planning and execution. Longitudinal studies are often considered to give very good results, because they are so long and can look at many different parts of people’s lives. Longitudinal studies are useful for studying changes in individuals over time in contrast to surveys, which provide a snapshot at a single point in time. Time, however, is itself one of the most important explanations of change. Therefore, longitudinal studies can give answers to questions concerning change that one-time surveys cannot.

By following children and families for 21 years or more, the NCS will collect information about health at different ages and stages of growth and in various situations, to possibly shed light on the factors that influence health and development as people grow.

As promised in last week’s post, for the next several weeks, we will be posting some outtakes that did not make it into our final set of Videovoice videos. In this week’s clip, Dr. Clavier talks about the importance of longitudinal studies:

As you heard, other large and long-term studies have really made a difference in our understanding of adult health. For example, the willingness of people in a small town in Massachusetts – Framingham – to take part in a study for more than 20 years showed us why smoking is bad for health, among many other things. To learn more about the Framingham study, check out this blog post.

Other studies have given us some clues about children’s health, but none of them was large enough or lasted long enough to give us the information we really need to understand more about children’s health and well-being. The NCS is different. Because the NCS starts before babies are even born and continues until they are young adults, it can tell us a lot more about what really matters when it comes to what makes kids healthy, makes them sick, or what keeps them safe.

The NCS offers our community the opportunity to take part in the largest long-term study of children ever. An unhealthy community affects everyone. If we can learn through a long-term study how homes, schools, and neighborhoods influence the health and safety of kids, we can perhaps address and prevent many health problems.

Community Voices

Seven months ago, the Greater Chicago Study Center (GCSC) embarked on a journey to engage our community partners to find out their thoughts and opinions about children’s health and the National Children’s Study (NCS). First, we asked community partners to recommend local parents active in their communities through volunteering, PTA, school council or other activities. We asked these parents to be GCSC Neighborhood Ambassadors and help advocate for the Study in their local communities.  For the next few weeks, we gathered as a group and gained knowledge and skills in filmmaking and interviewing. If you followed our postings on this blog between October 2011 and February 2012, you were able to see some of the progress that we made in reaching out to individuals all around Cook County. It quickly became evident that the time spent conducting these interviews about our children’s health concerns constituted a rewarding experience for all.

Since February, we have been very busy reviewing the many hours of footage filmed by our Neighborhood Ambassadors in an effort to distill them into concise informational videos. We learned much about some of the main health concerns shared by communities about Cook County children, including asthma, obesity, and diabetes. Some parents shared their personal stories regarding their own children being afflicted by some of these conditions. Additionally, local residents declared their excitement about the NCS because the Study is going to take a closer look at the environment where children are growing up and its relationship to children’s well-being. In fact, the holistic approach to environment, as well as the length and size of the Study, is what distinguishes the NCS from other studies. All of the people whom we approached were eager to express their support for the NCS because they understand its tremendous potential to improve the health of future generations.

After months of hard work, the GCSC is proud to launch Community Voices, two awareness campaign videos in English and Spanish as the result of our VideoVoice project:

We would love to hear your comments about the videos. Please click here to answer a short survey about the video.

As you can imagine, many interesting interviews did not make it into this final set of videos. Check back here next week, as we will post some of them for you.

As part of our mission at the Greater Chicago Study Center, we are committed to addressing issues related to health and well-being of children and their families. We thank you for helping us ensure the success of the National Children’s Study in Cook County.

May 14 - 18, 2012 is Food Allergy Awareness Week!

In observance of Food Allergy Awareness Week, the National Children’s Study Greater Chicago Study Center included a short Food Allergy Awareness Quiz in our monthly newsletter.

Here's where you can find the answers:

1. Food allergies can be cured with allergy shots.

False: There is no cure for food allergies. Avoiding the food is the only way to prevent an allergic reaction.



2. Milk is a common food allergen.

True: Milk is a common allergen. People who are allergic to milk must avoid cheese (pizza), ice cream, butter, yogurt, and all other foods that contain milk.


3. It’s okay to test if a food is safe by licking it or taking a tiny bite.

False: Even a tiny lick or bite of a food can cause a reaction. People with a food allergy must read the ingredient statement before eating a food.


4. If a person is having an allergic reaction you should not let them go off alone.

True: Sometimes symptoms start out mild, and the person might think it’s okay to go off alone. But, things can quickly get worse, so stick with them in case your help is needed.
