  • 40 to 49: 37%
  • 50 to 59: 5%

Summary of Results:

Key Findings

Five key themes were jointly decided based on the transcript:

  1. Amount of food stamps
    • Vast majority of participants reported that the amount of food stamps received was not adequate and many reported running out by mid-month
    • Inadequate food stamps also made the purchase of healthier foods more challenging for the participant.
  2. Alternative food resources: Participants were able to receive food through a variety of other sources when they ran out of food stamps including FoodBank, Salvation Army, churches, family members and friends
  3. Food security strategies
    • Participants employed a variety of stategies to help sustain the food stamps they had at their disposal. These included: Budgeting carefully, shopping for sales and shopping in bulk.
    • Some participants grew their own produce, while others purchased food from fast food establishments to supplement their food stamps.
  4. Lack of facilities
    • Participants made mention of not having adequate food storage and preparation areas
    • Many participants used "improvised" food storage such as ice, coolers and sharing with other families.
  5. High cost of living
    • Numerous reference were made in regards to the high cost of living in Hawaii
    • High costs were mentioned regarding gas, rent and groceries.
Author Conclusion:
  • Similar to other studies performed on populations with food security issues, FSP assistance was found inadequate and many participants reported running low before the end of the month
  • Participants were faced the challenge of budgeting their resources and many reported making choices that were not considered healthy when faced with lack of resources.

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
