Title: Bonny Specker, Ph.D.


1
National Childrens Study
  • Bonny Specker, Ph.D.
  • South Dakota State University

Brookings, Yellow Medicine, Pipestone Lincoln
Counties (BYPL) Vanguard Center
2
What is the National Childrens Study (NCS)?
  • Largest nationwide study of childrens health
  • Authorized by the Childrens Health Act of 2000
  • Supported by the National Institutes of Health
    (NIH), Centers for Disease Control Prevention
    (CDC), and the Environmental Protection Agency
    (EPA)

3
Outline of Talk The National Childrens Study
(NCS)
  • Reason for doing the study
  • Important facts about how the Study will work
  • Background on the Vanguard Centers
  • Things about the BYPL Vanguard Center that might
    be of interest
  • Timeline of events
  • BYPL Brookings, Yellow Medicine, Pipestone,
    Lincoln counties

4
Some Childhood Conditions are Increasing
of Children with Asthma 1981-2003
5
Some Childhood Conditions are Increasing
of Children Overweight 1963-2002
6
Some Childhood Conditions are Increasing
  • We suspect that the environment plays a part in
    these childhood conditions
  • Birth defects
  • Prematurity
  • Autism
  • Cerebral palsy
  • Type I diabetes
  • Mental retardation
  • Obesity
  • Asthma
  • Injuries

7
Children are NOT Little Adults
  • Children behave differently
  • Children are physically different
  • Harm is more possible at certain times in
    development

8
Children Behave Differently
  • Explore the world through touch and taste
  • Spend more time outdoors
  • Diet and eating habits differ

9
Children are Physically Different
  • Pound-for-pound, kids
  • Breathe more air than adults
  • Drink more water than adults
  • Eat more food than adults

10
Children are NOT Little Adults
  • Most chemicals to which children are exposed have
    not been tested
  • 80,000 chemicals in commerce
  • Danger to growing children is known for less than
    20 of these chemicals

11
Some Things Partly to Blame for Childhood Diseases
  • Mothers infections during pregnancy ?
    prematurity
  • Heavy metals (lead in paint, mercury in fish) ?
    developmental problems
  • Mothers exposure to pesticides ? developmental
    problems
  • Stress during pregnancy ? childhood asthma
  • Child television watching super-size me
    portions ? obesity

12
Why Do We Need the NCS?
  • The NCS will identify what is
  • Harmful
  • Harmless
  • Helpful
  • to child development

13
Facts about the NCS
  • Focuses on priority areas
  • National in scope (105 U.S. counties) and the
    group enrolled will provide a snapshot of all
    U.S. families
  • Families followed from before conception or in
    early pregnancy until age 21 years
  • Many different aspect of environment will be
    studied chemical, physical, social behavioral

  • Biological specimens will be stored so scientists
    can use these to answer health questions in the
    future

14
How Will Families be Identified?
  • 105 study locations were drawn from the full list
    of about 3,000 counties in the U.S.
  • Certain neighborhoods in these counties will be
    selected.
  • We will go door-to-door looking for women to
    enroll.
  • We also will ask for help from doctors caring for
    pregnant women.

15
Vanguard Locations
  • Precede other Study locations by two years
  • Finalize exactly what information will be
    collected
  • Pilot testing
  • 7 Vanguard Sites
  • BYPL Counties, South Dakota Minnesota
  • Duplin County, North Carolina
  • Montgomery County, Pennsylvania
  • Orange County, California
  • Queens County, New York
  • Salt Lake County, Utah
  • Waukesha County, Wisconsin

16
NCS Locations
17
Vanguard Center Comparisons
in 2003 LBWLow Birth Weight (less than 5½
pounds) Each site will contribute 1,250 births to
NCS
18
Types of Data Collected
  • Questionnaires Interviews medical history,
    dietary intake, product use
  • Environmental Samples Observations air, dust,
    soil, water, home observations
  • Physical Examinations fetal ultrasound
    measures, height, weight, blood pressure
  • Observation of Behavior mother-child
    interactions
  • Biological Samples blood, urine, umbilical cord
    blood, placenta, breast milk

19
Schedule of Visits
20
Large Size of the NCS
  • The NCS is large, long, and extensive because
    most studies
  • do not enroll enough children need large
    numbers to pull apart all the effects of
    different environmental influences
  • last for short periods of time do not follow
    the children as they get older and cannot see
    diseases resulting from long-term exposure to
    something harmful
  • are only done in one place may not represent
    all U.S. children

21
Associations Interactions in the NCS
22
Expected Benefits of the NCS
23
The National Childrens Study
  • What might be interesting about the BYPL counties?

24
The BYPL Communities
  • Land Area 2,555 square miles
  • Population 21 people/square mile
  • 44 live in urban clusters (2,500-5,000 people)
  • 56 live in rural areas (12 are actively
    farming)
  • 85 are high school graduates
  • 19 elementary schools
  • 17 high schools
  • 23 have a 4-year college degree
  • 12 live below poverty
  • 77 are affiliated with a church (137 churches)

25
Births in the BYPL Counties
26
Environmental Exposures in the BYPL Communities
  • Agricultural-related exposures
  • Pesticides
  • Accidents injuries
  • Significant number of older housing units ?
    possible increased lead exposure
  • In 2002, Brookings County ranked among the
    dirtiest/worst 20 of all counties in the U.S. in
    terms of air releases of recognized developmental
    toxicants.

27
BYPL NCS Vanguard Center Collaborators
  • South Dakota State University
  • EAM Program in Human Nutrition, Nursing,
    Engineering, Exercise Physiology, Human
    Development, Rural Sociology
  • Cincinnati Childrens Hospital Medical Center
  • Childrens Environmental Research Center
  • University of Cincinnati
  • Department of Environmental Health
  • Numerous local hospitals, clinics and physicians

28
BYPL Vanguard Center
  • 11 segments will be identified 7 of these
    randomly chosen
  • All women in these 7 segments will be approached
    (4,000 enrolled)
  • Expect 250 births/y for 5 years (N1,250)
