Disparities in Peanut Allergy Prevention Guidance Revealed Among US Parents

Strategic Insights -

A large Northwestern Medicine study reveals that white parents are more likely to introduce peanut-containing foods to their infants, reducing the risk of peanut allergies later in childhood. However, parents from racial and ethnic minority groups, lower-income families, and those with less formal education are less likely to receive this potentially lifesaving guidance from their pediatrician, leading to lower rates of early introduction. The study, which surveyed over 3,000 US parents in 2021, highlights stark disparities in the implementation of guidelines aimed at preventing peanut allergies.

Key Takeaways:

  • 51% of white respondents had introduced peanut-containing foods to their infants by the time their child turned one, compared to 42% of Black, 36% of Hispanic, and 35% of Asian American parents.
  • Early introduction was significantly more common among high-income and college-educated parents.
  • Only about half of Black and Hispanic parents said their pediatrician brought up the topic of peanut introduction, compared to nearly two-thirds of white parents.
  • 29% of Black parents believed peanut introduction before 12 months would help prevent peanut allergies, compared to 53% of white parents.
  • Families from low-income and minority groups already experience higher rates of food allergies and more severe outcomes.
  • The study suggests that primary care providers, especially those serving underserved communities, need better tools and resources to make early peanut introduction more equitable.
