Early Life Factors for Overweight Risk Among Infants of Hispanic Immigrant Mothers.

INTRODUCTION: This study examined postpartum depression, food insecurity, and underestimation of infant size as potential early life factors for overweight risk at 12 months among infants of Hispanic immigrant mothers. METHOD: Weight-for-length (WFL) measurements and face-to-face interviews were completed during well child visits. Regression models estimated the impact of early life factors (0-6 months) on overweight risk at 1 year. RESULTS: WFL ≥ 85th percentile was found among 2.4% at birth and 42.7% at 1 year. Most mothers (78.6%) experienced food insecurity, a factor that increased the likelihood of infant overweight risk by 2.29 times (1.03-5.09). Maternal underestimation of infant size increased the likelihood of overweight risk 5.07 times (2.57-9.99). Postpartum depression risk did not contribute to infant weight status. DISCUSSION: Assessment for maternal food insecurity and underestimation of infant weight status during early infancy may help reduce overweight risk and subsequent obesity for this vulnerable population.

Institute of Medicine Early Infant Feeding Recommendations for Childhood Obesity Prevention: Implementation by Immigrant Mothers From Central America.

PURPOSES: Describe implementation of Institute of Medicine (IOM) early infant feeding recommendations for child obesity prevention by immigrant mothers from Central America; examine potential relationships with food insecurity and postpartum depressive symptoms. DESIGN AND METHODS: Using a cross-sectional, descriptive design, face-to-face interviews were conducted with 318 mothers of 2month old infants at a large pediatric setting for low income families. Logistic regression models assessed feeding practices, food insecurity and postpartum depressive symptoms. RESULTS: Exclusive breastfeeding rates were low (9.4%); most mothers (62.7%) both breastfed and bottle fed their infants. Mothers who bottle fed at moderate and high intensity were twice as likely to affirm that if you give a baby a bottle, you should always make sure s/he finishes it (OR=2.30, 95% CI=1.13, 4.69; OR=2.29, 95% CI=1.26, 4.14). Food insecurity was experienced by 57% of mothers but postpartum depressive symptoms were low (Possible range=0-30; M=2.96, SD =3.6). However, for each increase in the postpartum depressive symptoms score, the likelihood of affirming a controlling feeding style increased by 11-13%. CONCLUSIONS: Immigrant mothers from Central America were more likely to both breastfeed and bottle feed (las dos cosas) than implement exclusive breastfeeding. Bottle feeding intensity was associated with a controlling feeding style. PRACTICE IMPLICATIONS: Infant well visits provide the ideal context for promoting IOM recommendations for the prevention of obesity among children of immigrant mothers from Central America.

Sensitive Timing for Risk of Overweight Among Infants of Low-Income Hispanic Immigrants.

INTRODUCTION: This study examined the association between early weight gain (0-6 months) and risk for overweight, as defined by the Institute of Medicine, at 1 year among infants of low-income Hispanic immigrant mothers. METHOD: Weight-for-age data were extracted from electronic medical records of 335 infants with gestations of 37 weeks or longer and birthweights appropriate for gestational age and without medical problems likely to interfere with growth or feeding. Logistic regression models were constructed to examine the impact of early weight changes on weight status at 1 year. RESULTS: By 12 months, 36.7% of infants had crossed weight-for-age of 84.1% or greater on World Health Organization growth charts. In adjusted models, infants had 20.8 (95% confidence interval = [19.8, 44.0]) times the odds of reaching this benchmark at 1 year for each z score increase at 0 to 6 months. DISCUSSION: The study highlights a time-sensitive opportunity for interventions to reduce risk for overweight for this vulnerable population.

Early Feeding Practices and Weight Status at One Year of Age: A Comparison of Hispanic Immigrant Mother-Infant Dyads with Participants of the Infant Feeding Practices Study II.

BACKGROUND: Hispanic preschoolers have higher rates of BMI ≥85th percentile than any other racial/ethnic group. To identify underpinnings of this disparity, we compared early feeding practices and subsequent weight status for a sample of infants of low-income, Hispanic immigrant mothers with participants from the Infant Feeding Practices Study II (IFPS II). METHODS: Proyecto de Bebés Hispanos Saludables (PBHS) collected medical record data for mother-infant dyads (n = 550) from a large pediatric clinic for low-income families and merged it with IFPS II data (n = 1502) to compare early feeding practices and late infancy weight status. RESULTS: Mode of milk delivery for PBHS mothers was less likely to be exclusive breastfeeding at 6 months (9.0% vs. 27.5%), but more likely to be both breast and bottle feeding (43.5% vs. 26.3%) compared to IFPS II mothers. No difference was found in age for solid food introduction. Weight for age of PBHS infants was more likely to be ≥85th percentile at 12 months than IFPS II infants (39.1% vs. 25.4%). Both PBHS and IFPS II infants were more likely to be ≥85th percentile at 1 year if mode of milk delivery was bottle only at 6 months compared to those who were breastfed only, even after adjusting for potential confounders. CONCLUSION: Differences in PBHS and IFPS II feeding practices and weight status suggest additional studies of modifiable, early life risk factors are needed to inform clinical and public health interventions that reduce childhood obesity for this growing sector of the US population.
