Insights
US hospitals are increasingly reducing infant formula sample packs. While most still distribute them, the proportion of sample-pack-free hospitals significantly increased between 2007 and 2010.
Area of Science:
- Public Health
- Healthcare Policy
- Infant Nutrition
Background:
- Industry-sponsored infant formula sample packs are commonly distributed by US hospitals.
- Previous studies indicated a high prevalence of formula sample pack distribution in maternity services.
- Concerns exist regarding the impact of these samples on infant feeding practices and maternal health outcomes.
Purpose of the Study:
- To track changes in the distribution of infant formula sample packs by US hospitals from 2007 to 2010.
- To assess trends in sample pack elimination among hospitals in selected states.
- To identify potential factors influencing changes in hospital distribution practices.
Main Methods:
- A follow-up study analyzing hospital practices in 2010, building on a 2007 survey.
- Targeted 20 states based on 2007 formula sample pack distribution records (10 best and 10 worst).
- Hospitals were contacted to determine if they distributed "formula company-sponsored diaper discharge bags" to new mothers.
Main Results:
- The proportion of "sample-pack-free" hospitals increased from 14% in 2007 to 28% in 2010.
- In the 10 best-record states, the increase in sample-pack-free hospitals was 18% (P < .0001).
- In the 10 worst-record states, the increase was 6% (P < .01), with variations by state (0% to 86% sample-pack-free).
Conclusions:
- Most US hospitals continue to distribute infant formula sample packs, but a significant trend towards elimination is evident.
- The rate of change was more pronounced in states that already had higher proportions of sample-pack-free hospitals in 2007.
- These findings suggest a shift in hospital practices regarding infant formula promotion.
Objective:
To describe trends in the proportion of US hospitals that distribute industry-sponsored formula sample packs between 2007 and 2010.
Methods:
This is a follow-up of a 2007 study. In 2007, we surveyed all 50 US states to determine the proportion of hospitals that distributed infant formula samples to new mothers. In 2010, we selected the 10 best-record and 10 worst-record states with regard to industry-sponsored formula sample-pack distribution in 2007. We called all hospitals in these 20 states and asked if the maternity service distributed a "formula company-sponsored diaper discharge bag" to new mothers. We also recorded the respondent's job title.
Results:
We contacted 1239 hospitals in 20 states. In 2007, 14% of these hospitals were sample-pack-free. In 2010, 28% of the same hospitals were sample-pack-free; the proportion of sample-pack-free hospitals per state ranged from 0% (5 states) to 86% (Rhode Island). In the 10 best-record states, the weighted proportion of sample-pack-free hospitals increased by a mean difference of 18% between 2007 and 2010 (P < .0001). In the 10 worst-record states, the weighted proportion of sample-pack-free hospitals increased by a mean difference of 6% (P < .01).
Conclusion:
Most US hospitals continue to distribute industry-sponsored formula sample packs, but trends indicate a significant change in practice; increasing proportions of hospitals eliminate these packs. Change was more significant in states where higher proportions of hospitals had already eliminated packs in 2007.
