Factors contributing to infant overfeeding with Hispanic mothers

To evaluate existing evidence on factors potentially contributing to infant overfeeding among Hispanic mothers that may explain the high infant overweight rates often seen among this ethnic group.

Electronic databases including CINHAL and MEDLINE were searched for relevant studies published from 1998 to January 2012. Related article searches and reference list searches were completed on all included studies.

Thirty-five studies (nine qualitative, 15 cross-sectional, nine cohort, and two longitudinal) were identified that met the following inclusion criteria: (a) studies of Hispanic-only or multiethnic mothers, (b) studies of healthy full-term infants or toddlers, (c) studies in which a majority of the sample included children within the target age group (0-24 months of age), and (d) studies conducted in the United States. The methodological quality of the studies ranged from fair to excellent.

Data extraction included content related to Hispanic infant feeding and weight gain.

Reviewed research fell into three main foci of inquiry: breastfeeding and formula-feeding beliefs, attitudes, and practices; family and cultural influences of maternal feeding beliefs and practices; and maternal perceptions of infant feeding satiety and weight gain. The Preferred Reporting Items of Systematic Reviews Meta-Analysis (PRISMA) guidelines were followed for data extraction and reporting the results of this integrative review.

Three major feeding practices and beliefs among Hispanic mothers potentially contribute to infant overfeeding. Hispanic mothers are more likely to practice nonexclusive breastfeeding, initiate early introduction of solid foods including ethnic foods, and perceive chubbier infants as healthy infants. Cultural norms driving family influences and socioeconomic factors play a role in the feeding tendencies of Hispanics. Empirical research is needed to further define the primary factors that influence Hispanic mothers feeding decisions and practices that contribute to excessive weight gain in their infants.
