New Jersey Childhood Obesity Study, 2009-2010 (ICPSR 34364)

Principal Investigator(s): Yedidia, Michael, Rutgers University Center for State Health Policy


This survey was conducted as part of the New Jersey Childhood Obesity Study, a project designed to provide vital information for planning, implementing, and evaluating interventions aimed at preventing childhood obesity in five New Jersey municipalities: Camden, Newark, New Brunswick, Trenton, and Vineland. Conducted among households with 3-18 year old children in the 5 cities, the survey interviewed the adult who made most of the decisions about food shopping in each household. The survey examined perceptions about food and physical activity environments in the five cities, investigated barriers related to access to healthy food and physical activity facilities, and collected information on the height and weight and food and physical activity behaviors of the cities' 3-18 year old children and the adult respondents. In addition, the survey collected demographic information about the household members.

Four linkable datasets contain the survey data: the Household File, Index Child File, Adult File, and All Child File. The Household File covers household and neighborhood characteristics, while the Index Child File describes the characteristics and behaviors of a randomly selected 3-18 year old child in the household, who is designated the "index child" and is the primary unit of analysis. The Adult File comprises characteristics and behaviors of the adult respondent, and, lastly, the All Child File covers a few characteristics of all children aged 3-18 in the household.

Scope of Study

Subject Terms:    body weight, child nutrition, children, exercise, food, food preferences, nutrition, obesity, physical condition

Geographic Coverage:    Camden, New Brunswick, New Jersey, Newark, Trenton, United States, Vineland

Time Period:   

  • 2009--2010

Date of Collection:   

  • 2009--2010

Universe:    Households in Camden, New Brunswick, Newark, Trenton, and Vineland, New Jersey with at least one child aged 3-18 years.

Data Type(s):    survey data

Data Collection Notes:

The data files include computed Body Mass Indices (BMI) for the adult respondent and 3-18 year old children.


Sample:    Independent samples were drawn from each of the five cities using random-digit-dialing sampling with additional address-based sampling in New Brunswick. Altogether, 1,708 interviews were completed: 400 from Camden, 400 from Newark, 208 from New Brunswick, 400 from Trenton, and 300 from Vineland.

Mode of Data Collection:    computer-assisted telephone interview (CATI)

Response Rates:    The overall response rate was 49 percent.

Presence of Common Scales:    Body Mass Index

Extent of Processing:   ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Checked for undocumented or out-of-range codes.
