Maternal Mental Health and Infant Dietary Patterns in a Statewide Sample of Maryland WIC Participants

This study looked at the relationship between maternal health and infant dietary patterns in WIC participants in Maryland. Data from 689 mother-infant pairs revealed the following: A total of 36.5% of mothers reported introducing solids to their infants early (<4 months of age), and 40% reported adding cereal to their infant's bottle. Overall, results demonstrated that maternal mental health symptoms were associated with poorer infant-feeding practices and higher infant dietary intake during the first 6 months.


A Diet Quality Index for Pregnancy Detects Variation in Diet and Differences by Sociodemographic Factors

The authors examines dietary intake of pregnant women using the Diet Quality Index for Pregnancy (DQI-P), a new index developed to reflect current nutritional recommendations for pregnancy and national dietary guidelines. The highest overall DQI-P scores were identified in women who were older than 30, above 350% of the poverty level, nulliparous, and high school graduates. Additionally, higher-income, older, and better-educated women consumed higher amounts of vegetables. But, black, low-income, and nulliparous women consumed greater intakes of folate and iron.


Maternal Symptoms of Stress, Depression, and Anxiety Are Related to Nonresponsive Feeding Styles in a Statewide Sample of WIC Participants

This study assessed maternal mental health and feeding styles by a telephone survey. Parenting, including non responsive feeding styles, has been related to young children being either under- or overweight. Mothers who reported stress, depression, or anxiety symptoms were at risk of non responsive feeding styles. These findings provided support for broadening the focus of existing child nutrition programs to include strategies that recognize how issues of maternal mental health could affect feeding styles.


Maternal Depressive Symptoms and Infant Health Practices Among Low-Income Women

The aim of this study was to determine the relationships between maternal depressive symptoms and the use of infant health services, parenting practices, and injury-prevention measures. A total of 48% of women had depressive symptoms at one or two time points (ever symptoms), and 12% had depressive symptoms at all points (persistent symptoms). There was no association between maternal depressive symptoms and infant receipt of well-child care or the likelihood of breastfeeding for 1 month or longer.


Reducing Low Birth Weight Through Home Visitation: A Randomized Controlled Trial

This study assessed the effectiveness of a prenatal home visitation program in reducing adverse birth outcomes among socially disadvantaged pregnant women and adolescents. The risk of delivering a  low-birth weight baby was significantly lower for the intervention group. The risk was further reduced for mothers who were exposed to the intervention at a gestational age of 24 weeks or fewer.


Racial Disparity in the Frequency of Recurrence of Preterm Birth

This study examines the hypothesis that ; independent of other factors, being black increased the risk of extreme preterm birth and its frequency of recurrence at a similar gestational age. The study found that recurrent black preterm births occurred at increased frequency and at an earlier gestation age (median age: 31 weeks versus 33 weeks), when compared with white births.


Psychosocial Predictors of Being an Underweight Infant Differ by Racial Group: A Prospective Study of Louisiana WIC Program Participants

The researchers identified psychosocial predictors of having low-birth weight infants among mothers enrolled in the Louisiana WIC Program. Among blacks, mothers with an eighth grade education or less had the highest risk of having underweight infants. Among whites, those who initiated prenatal care in the third trimester were most likely to have underweight infants.


The Relationship Between the Neighbourhood Environment and Adverse Birth Outcomes

The aim of this study was to explore whether conditions of mothers; neighbourhood of residence contributed to adverse birth outcomes, independent of individual-level determinants. Results suggested that measures of neighbourhood economic conditions were associated with both fetal growth and the length of gestation, independent of individual-level factors.
