“…The odds of LBW were about three times higher in mothers found to be in household food insecurity than those in food security. This finding is in line with studies conducted in Addis Ababa 15 and Afar, Ethiopia, 16 rural Haiti 17 and Pakistan, 18 which stated that food-insecure women had an increased risk of delivering an LBW newborn. This may be because food insecurity among women during pregnancy ranges up to 90% in underdeveloped and developing countries.…”

Background: More than 20 million births annually in developing countries are classed as low birth weight, with short-and long-term consequences. Food insecurity is the major determinant of low birth weight in developing countries. Objective: This study aimed to identify the effects of food insecurity and other possible factors associated with low birth weight in West Wollega, West Ethiopia. Methods: This facility-based unmatched case-control study was conducted among mothers who gave birth to live newborns in randomly selected hospitals in West Wollega. Data were collected using a structured interviewer-administered questionnaire. Collected data were coded and entered into Epi Info version 7.2.0.1 and analyzed by SPSS version 24. Adjusted odds ratios were used to identify predictors of low birth weight at a p-value less than 0.05. Results:The study indicated that the mother living in a food-insecure household (AOR [95% CI] = 2.9 [1.05-8]), uneducated mother (AOR [95% CI] = 5 [1.8-14]), birth interval of <24 months (AOR [95% CI] = 4.6 [1.2-18]), age at first birth of <18 years (AOR [95% CI] = 4 [1.1-15]), late initiation of antenatal care (ANC) (AOR [95% CI] = 4.4 [1.3-15.7]), pregnancyinduced hypertension (AOR [95% CI] = 3.6 [1.03-12.9]), and maternal mid-upper arm circumference (MUAC) of <23 cm (AOR [95% CI] = 11 [4-35]) were predictors of low birth weight. Conclusion:Household food insecurity, a birth interval of <24 months, age at first birth <18 years, late initiation of first ANC, pregnancy-induced hypertension, and maternal MUAC of <23 cm were predictors of low birth weight in this study. Early screening for medical and obstetric conditions, as well as maternal nutritional status and household food insecurity, is a key action needed to reduce low birth weight in this study area.

“…Premature birth and SGA are considered the main causes of adverse neonatal outcomes worldwide. 22 The association between food environments and fetal growth is a controversial issue. However, our study's results align with the literature that considers that these environments may reinforce the effects of a poor diet, compromising perinatal and neonatal outcomes 13,22,[24][25][26][27] .…”

Introduction Birth weight is described as one of the main determinants of newborns’ chances of survival. Among the associated causes, or risk factors, the mother’s nutritional status has a strong influence on fetal growth and “birth weight” outcomes of the concept. This study evaluates the association between food deserts in small for gestational age (SGA), large for gestational age (LGA) and low birth weight (LBW) newborns. Design This is a cross-sectional population study, resulting from individual data from the Live Birth Information System (SINASC), and municipal data from mapping food deserts (CAISAN) in Brazil. The newborn’s size was defined as follows: appropriate for gestational age (between 10 th and 90 th percentile), SGA (<10 th percentile), LGA (>90 th percentile), and low birth weight <2,500g. To characterize food environments, we used tertiles of the density of establishments which sell in natura and ultra-processed foods. Logistic regression modeling was conducted, in order to investigate the associations of interest. Results We analyzed 2,632,314 live births in Brazil in 2016. Following due adjustment, it was observed that women from municipalities in which there was a limited supply of in natura foods presented a higher chance of a SGA [OR 2nd tertile :1.06 (1.05-1.07)] and LBW [OR 2nd tertile : 1.11(1.09-1.12)] newborn. On the other hand, municipalities in which there was a greater supply of ultra-processed foods presented higher chances for a SGA [OR 3rd tertile :1.04 (1.02-1.06)] and LBW [OR 2nd tertile :1.13 (1.11-1.16)] newborn. Stratification showed that black and mixed-race women were associated with SGA [OR 3rd tertile : 1.09 (1.01-1.18)] and [OR 3rd tertile :1.06 (1.04-1.09)], respectively, and mixed-race women were also associated with LBW [OR 3rd tertile :1.17 (1.14-1.20)], while indigenous women were associated with LGA [OR 3rd tertile : 1.20(1.01-1.45)]. Conclusions Living in areas with limited access to healthy foods was associated with an increased chance of SGA and low weight newborns, especially in black and mixed-race women. Initiatives focused on minimizing the effects of these food environments, and which aim to reduce social inequalities are urgently required in the Brazilian context.

“…Similarly, higher numbers of convenience stores within a one-mile radius of a pregnant woman's household have been associated with a higher risk of preterm birth and low birth weight [19]. Further research has linked food insecurity (i.e., inconsistent access to adequate and nutritious food) and poor diet quality to pregnancy morbidity, including gestational diabetes, IUGR, and preterm birth [15,20,21].…”

A Mixed Methods Case Study of Food Shopping in a Community with High Infant Mortality

In the U.S., preterm birth disproportionately impacts certain racial/ethnic groups, with Black women experiencing preterm birth at a rate 50% higher than other groups. Among the numerous factors that likely contribute to these increased rates are neighborhood characteristics, such as food environment. In this mixed-methods case study, we evaluated how pregnant women living in a predominately minority, lower income community with high preterm birth rates navigate and perceive their food environment. Qualitative interviews were performed to assess perceptions of food environment (n = 7) along with geographic and observational assessments of their food environment. Participants traveled an average of 2.10 miles (SD = 1.16) and shopped at an average of 3 stores. They emphasized the importance of pricing and convenience when considering where to shop and asserted that they sought out healthier foods they thought would enhance their pregnancy health. Observational assessments of stores’ nutrition environment showed that stores with lower nutritional scores were in neighborhoods with greater poverty and a higher percent Black population. Future policies and programmatic efforts should focus on improving nutrition during pregnancy for women living in communities with high rates of poor birth outcomes. Availability, affordability, and accessibility are key aspects of the food environment to consider when attempting to achieve birth equity.
