Summary of Results:

Key Findings

  • Livelihood Strategies (percentages sum greater than zero because multiple strategies were used)
    • 51% employment
    • 44.1% government assistance
    • 45% informal support, cash assistance from others (absent fathers, boyfriends, relatives)
    • 43% help from churches and social agencies, such as food banks
    • 58% cohabitating
    • 25% co-residing with a friend or relative
    • 27% engaged in belt-tightening actions (making cheaper and smaller meals)
    • 18% used a senior meal program 
  • Psychological Components of Food Insecurity
    • 65% worried food would run out before they could get money for more
    • 47.8% felt depressed
    • 56.7% felt sad
    • 45.5% felt lonely
    • 49.6% had trouble sleeping
    • 47.7% had trouble concentrating.
Author Conclusion:
  • Network-based survival strategies are present among poor African American single mothers
  • Food stamps did not figure prominently in their actions to deal with food insecurity
  • Earning an income was preferred over living on welfare
  • New and innovative solutions may be needed to ensure food security of low-income families
    • Improving local employment and job availability
    • Psychological counseling.

Reviewer Comments:

Study states 100 African-American single mothers from rural Alabama were recruited and interviewed, data describes 85.7% of participants as African American.

Quality Criteria Checklist: Primary Research
Relevance Questions
  1. Would implementing the studied intervention or procedure (if found successful) result in improved outcomes for the patients/clients/population group? (Not Applicable for some epidemiological studies) Yes
  2. Did the authors study an outcome (dependent variable) or topic that the patients/clients/population group would care about? Yes
  3. Is the focus of the intervention or procedure (independent variable) or topic of study a common issue of concern to dieteticspractice? Yes
