Class:
D - Click here for explanation of classification scheme.
Quality Rating:
Neutral NEUTRAL: See Quality Criteria Checklist below.
Research Purpose:

To measure the level of food security and hunger of households involved in HS in a nonmetropolitan Appalachian county and assess factors that could affect food security and hunger.

Inclusion Criteria:

Families with children currently enrolled in HS (Head Start) in Athens County, Ohio.

Exclusion Criteria:

None noted.

Description of Study Protocol:
  • Recruitment: Recruitment was not described. The sample was a convenience sample of all households with children currently enrolled in Head Start in Athens County, Ohio. 
  • Design: Cross-sectional
  • Blinding used: N/A
  • Intervention: N/A.

Statistical Analysis

  • Spearman correlation: Used to assess the relationship of food security status to the number of food assistance programs participated in
  • Odds ratios: Used to compare the presence of food insecurity with hunger to other variables.
Data Collection Summary:

Timing of Measurements

A 55-item survey instrument posed questions to subjects about the previous 12 months and included the 18-question US Household Food Security Survey Module (FFSM). The survey instrument was distributed on two separate days in January 2001 by the Head Start Program Director to adults with children enrolled and returned to the sites by adult respondents within one week of distribution. 

Dependent Variables

  • Food security
  • Hunger.

Independent Variables

Factors affecting hunger and food security (i.e., money).

Control Variables

Geography [(non-metropolitan, distressed county (most severe economic level category)].

Description of Actual Data Sample:
  • Initial N: 710 adults
  • Attrition (final N): 297 adults (222 female, 42 male, 33 other or no response)
  • Age: Not noted
  • Ethnicity: Not noted
  • Other relevant demographics: Participants were sampled from the Appalachian region of the US, which has been classified as a distress county (most severe economic level category) based on the economic indicators of unemployment, per capita market income and poverty
  • Anthropometrics: Not noted
  • Location: Athens County, Ohio.
Summary of Results:

Key Findings

  • Of the 297 adults that responded, 152 (51.2%) were food secure and 145 (48.8%) were food insecure
  • 90 (30.3%) had experienced hunger in the previous 12 months
  • 41 (13.8%) households were food insecure with childhood hunger
  • The rates of food insecurity are three times the national average for households with children (48.8% vs. 16.1%)
  • Childhood hunger was over 20 times higher than the national average (13.8% vs. 0.6%)
  • The current sample experienced food insecurity (48.8% vs. 17.2%) and hunger (13.8% vs. 0.2%) to a more severe degree than rural households with children, nationally
  • Participation in a greater number of food assistance programs was associated with poorer food security status (P=0.519)
  • A forward-stepwise logistic regression analysis was performed and showed the following
    • Participating in food banks: P<0.001
    • Depending on family members and friends outside of the household for food: P=0.001
    • Lacking reliable transportation: P<0.001
    • Lacking a garden: P=0.009.
Author Conclusion:
  • This study finds that the sample of Appalachian Ohio households with children enrolled in Head Start experienced a higher degree of food insecurity than what is typical for a state or region
  • Although the sample is not representative of households in the region or those enrolled nationally in Head Start, these findings suggest that rural households with children enrolled in Head Start may experience food insecurity and hunger at dramatically grater rates than the national averages
  • No two-way interactions among outcome variables of food insecurity and hunger were significant.

Reviewer Comments:
  • A limitation of the study may be the literacy rates of the subjects. Those unable to read may not have participated.
  • The season of the year (Winter) may have affected the results, because families often make choices between buying food and paying other bills
  • The study was limited by its non-random sample.

Relevance Questions
