Describe experiences of, and responses to, 2022 infant formula shortages among households with infants aged up to 18 months by race/ethnicity using Household Pulse Survey data.
Outcomes included whether households were affected by shortages and, if so, 3 nonmutually exclusive response categories (increased breastmilk, obtained formula atypically, and disruptive coping [disruptions to breastmilk and/or formula]) and 1 mutually exclusive response category (solely disruptive coping). Unadjusted shares reporting each were compared using t tests. Regressions adjusting for household characteristics and fixed effects were used to examine associations between race/ethnicity and the outcomes.
Shares affected by shortages declined over time as the formula supply improved. We found no association between race and ethnicity and reports of being affected by a shortage. Among affected households, non-Hispanic Black households were more likely to report disruptive coping than non-Hispanic White households (P = 0.03).
Shortages may have widened racial/ethnic differences in infant feeding practices. Efforts to inform about infant feeding behaviors, improve access to formula, and/or increase participation in assistance programs could be targeted to those most likely to be affected by unexpected shortages or most likely to resort to disruptive coping behaviors. Further research could examine geographic variation in shortages and their long-term effects on infant feeding behaviors and infant and maternal health.
利用家庭脉搏调查数据,按种族/族裔描述2022年18个月及以下婴儿家庭中婴儿配方奶粉短缺的经历及应对措施。
结果包括家庭是否受到短缺影响,若受影响,则包括3个非互斥的应对类别(增加母乳喂养、非典型获取配方奶粉以及干扰性应对[母乳喂养和/或配方奶粉供应中断])和1个互斥的应对类别(仅干扰性应对)。使用t检验比较报告各结果的未调整比例。采用对家庭特征和固定效应进行调整的回归分析,以检验种族/族裔与结果之间的关联。
随着配方奶粉供应改善,受短缺影响的比例随时间下降。我们发现种族和族裔与受短缺影响的报告之间无关联。在受影响的家庭中,非西班牙裔黑人家庭比非西班牙裔白人家庭更有可能报告干扰性应对(P = 0.03)。
短缺可能扩大了婴儿喂养方式上的种族/族裔差异。为告知婴儿喂养行为、改善配方奶粉获取途径和/或增加参与援助项目而做出的努力,可以针对那些最有可能受到意外短缺影响或最有可能采取干扰性应对行为的人群。进一步的研究可以考察短缺的地理差异及其对婴儿喂养行为以及婴儿和母亲健康的长期影响。
