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.


Barriers to the Use of WIC Services

This study identified barriers that deterred parents/caretakers of infants and children enrolled in the WIC Program from taking full advantage of the services provided by the program. Waiting too long was the most frequently cited barrier (48%). Difficulties in bringing the infant/child to recertify and rescheduling appointments were key variables associated with failure to use (i.e., pick up or cash) WIC checks.


Barriers to Prenatal Care for Homeless Pregnant Women

The purpose of this study was to explore and describe the barriers to prenatal care for homeless pregnant women. Based on the results, 75.61% of the respondents perceived barriers to prenatal care. Site-related factors were the most significant, followed by provider ;client relationship, inconvenience, fear, and cost.


Multiple Micronutrients in Pregnancy and Lactation: An Overview

This overview of micronutrients during pregnancy and lactation emphasized two relatively neglected issues: (1) the importance of maternal micronutrient status in the periconceptional period, as well as throughout pregnancy and lactation, and (2) the occurrence of simultaneous multiple micronutrient deficiencies when diets are poor. Unfortunately, information is lacking on the optimal formulation of micronutrient supplements for pregnant and lactating women.


Position of the American Dietetic Association: Nutrition and Lifestyle for a Healthy Pregnancy Outcome

This position paper looked at women of childbearing ages and the importance of maintaining good nutritional status, through a lifestyle to optimize maternal health and reduce the risk of (1) birth defects, (2) suboptimal fetal growth and development, and (3) chronic health problems in their children. Most pregnant women need 2,200 to 2,900 kcal a day. However, body mass index before pregnancy, rate of weight gain, maternal age, and appetite must be taken into consideration for each individual.


Maternal Nutrition and Birth Outcomes

In this review, the authors summarized current knowledge on maternal nutritional requirements during pregnancy, with a focus on birth outcomes. The researchers concluded that maternal nutrition was a modifiable risk factor of public health importance that could be integrated into efforts to prevent adverse birth outcomes, particularly among economically developing/low-income populations.


Assessing Diet Quality in a Population of Low-Income Pregnant Women: A Comparison Between Native Americans and Whites

This study evaluated the diet quality of pregnant women in the North Dakota WIC Program, comparing Native Americans with whites. The differences in diet quality, while significant, were minimal. In general, their diets were not meeting recommendations. The researchers recommended interventions that targeted decreasing fat and increasing iron and folate, as well as increasing consumption of fruits and vegetables.


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.
