Abstract
Introduction: Offsprings from a prenatal docosahexaenoic acid (DHA) supplementation trial, in which pregnant women were assigned to placebo or 600mg DHA/day, were followed to determine the effect of prenatal DHA supplementation on the behavior and brain function at 5.5 years (n=81 placebo, n=86 supplemented).Methods: Event-related potentials (ERP) were recorded during a visual task requiring a button press (Go) to frequent target stimuli and response inhibition to the rare stimuli (No-Go). Univariate ANOVAs were used to test differences between group and sex for behavioral measures. ERP differences were tested using a three-way mixed-design multivariate analysis of variance (MANOVA).Results: There was a significant sex × group interaction for hit rate and errors of omission; there was no difference between males and females in the placebo group, but DHA males outperformed DHA females. Males overall and the placebo group made more errors requiring response inhibition; DHA females were significantly better than placebo females and DHA males. ERP P2 amplitude was larger in the DHA group. A significant N2 amplitude condition effect was observed in females and DHA group males, but not in placebo group males.Discussion: Prenatal DHA supplementation improved inhibitory performance overall, especially for females in the DHA group, possibly accounting for their conservative behavior during Go trials. Development of brain regions responsible for visual processing may be sensitive to maternal DHA status, evidenced by greater P2 amplitude. Males may benefit more from maternal DHA supplementation, indicated by the N2 condition effect seen only in males in the DHA group.

Abstract
BACKGROUND & AIMS Nutritional challenges following bariatric surgery can be intensified during pregnancy and may have crucial effects on the fetus, including lower birth weight. To the best of our knowledge, the effect of nutritional counseling during post-bariatric pregnancy to improve maternal diet quality and eating habits on neonatal outcome has not been evaluated. The aim of this research was to examine the effects of personal nutritional counseling during post-bariatric pregnancy on nutritional intake and neonatal outcomes. METHODS We performed a non-randomized, intervention-control clinical trial. Women (n = 61) were divided into three groups; two prospective, and one retrospective: 1. An Intervention Bariatric Prospective group 2. A Control Prospective group without surgery, and 3. A Control Bariatric Retrospective group. Patient enrollment was performed from April 2016 to March 2018. The intervention program included biweekly visits with a pregnancy nutrition certified bariatric dietitian. Data collection was performed four times during pregnancy, and included demographic and eating habits questionnaires, 24 h dietary recall, and information about delivery outcomes. In the retrospective group delivery outcomes and Food Frequency Questionnaire was collected once, after delivery. RESULTS There were no differences between groups at baseline except for a higher pre-pregnancy BMI in the post-bariatric groups. In the prospective groups, dietary protein, energy, and iron were found to be consumed in higher amounts in the Control-Prospective group than in the Intervention Bariatric-Prospective group (p < 0.05), without the addition of supplements. On the other hand, iron and calcium calculated from diet with supplements, were found to be significantly higher in the Intervention Bariatric Prospective group than in the Control Prospective group. In addition, consumption of saturated fats, oil, and salty snacks was lower in both prospective groups compared to the retrospective group (p < 0.05), suggesting better food quality habits for the bariatric group with nutritional counseling. Mean birth weight was significantly lower in the Control Bariatric Retrospective group than in the Control-Prospective group (3074 ± 368 g vs. 3396 ± 502 g, respectively. p = 0.023). In the Intervention Bariatric Prospective group, mean birth weight was 3168 ± 412 g, and no significant difference was observed from the Control Prospective group. Birth percentiles were also significantly lower in the Control Bariatric Retrospective group compared to the Control Prospective group (27th vs. 42nd, respectively. p < 0.05). In the Intervention Bariatric Prospective group, mean birth percentile was 35th, and no significant difference was observed from the Control Prospective group. As for the weight change of the woman during pregnancy, the highest variability was noted among the Control Bariatric Retrospective group with cases of weight loss up to 37 kg, due to conception close to the bariatric operation. Nevertheless, this variable was controlled, and showed no significant impact on birth weight results. CONCLUSIONS Our results suggest that personalized nutritional counseling care during post bariatric pregnancy improved nutrient intake of mothers and may contribute to higher birth weight of offspring. Further research is needed to examine the effects of prenatal nutrition care intervention, in addition to repeating this trial with a larger sample size, to allow for clearer findings.

Abstract
OBJECTIVE To examine the associations of a clinical and public health systems-change intervention on the prevalence of excess gestational weight gain among high-risk, low-income women. METHODS In a quasi-experimental trial, we compared the prevalence of excess gestational weight gain among women before (n=643) and after (n=928) implementation of the First 1,000 Days program in two community health centers in Massachusetts. First 1,000 Days is a systematic program starting in early pregnancy and lasting through the first 24 months of childhood to prevent obesity among mother-child pairs. The program includes enhanced gestational weight gain tracking and counseling, screening for adverse health behaviors and sociocontextual factors, patient navigation and educational materials to support behavior change and social needs, and individualized health coaching for women at high risk for excess gestational weight gain based on their prepregnancy body mass index (BMI) or excess first-trimester weight gain. The primary outcome was gestational weight gain greater than the 2009 Institute of Medicine (now known as the National Academy of Medicine) guidelines according to prepregnancy BMI. RESULTS Among 1,571 women in the analytic sample, mean (SD) age was 30.0 (5.9) years and prepregnancy BMI was 28.1 (6.1); 65.8% of women started pregnancy with BMIs of 25 or higher, and 53.2% were Hispanic. We observed a lower prevalence (55.8-46.4%; unadjusted odds ratio [OR] 0.69, 95% CI 0.49-0.97), similar to results in a multivariable analysis (adjusted OR 0.69, 95% CI 0.49-0.99), of excess gestational weight gain among women with prepregnancy BMIs between 25 and 29.9. Among women who were overweight at the start of pregnancy, the lowest odds of excess gestational weight gain were observed among those with the most interaction with the program's components. Program enrollment was not associated with reduced excess gestational weight gain among women with prepregnancy BMIs of 30 or higher. CONCLUSIONS Implementation of a systems-change intervention was associated with modest reduction in excess gestational weight gain among women who were overweight but not obese at the start of pregnancy.

Abstract
BACKGROUND Nearly half of all pregnancies in the United States are reported as unintended and rates are highest among women of low socioeconomic status. The purpose of this study was to examine the associations between unintended pregnancies and maternal mental health and timing of prenatal care among low-income women. METHODS In this cross-sectional study, 870 women, whom were participating in the First 1000 Days program in three community health centers in the Boston area, were enrolled at their first prenatal visit from August 2016 - September 2017. We assessed pregnancy intention by self-report using the Pregnancy Risk Assessment Monitoring System. We used self-reported survey information and electronic health record data to assess the following outcomes: current stress, current depression, and timing of initial prenatal visit. We used multivariable logistic regression models to examine associations and adjusted for sociodemographic factors. RESULTS Women were a mean (SD) age of 29.3 (6.1), and 39.2% reported that their pregnancy was unintended. 50.6% of women were Hispanic, 28.4% were White, 10.1% were Black, and 10.9% were other races. 78.9% of women reported an annual household income <$50,000. Overall, 26.7% of women reported current stress, 8.2% reported current depression, and 18.3% of women initiated prenatal care after their first trimester. In multivariable analyses, women with unintended pregnancies had higher odds of experiencing current stress (OR: 1.72; 95% CI: 1.22, 2.41), current depression (OR: 1.83; 95% CI: 1.04, 3.20), and initiation of prenatal care post-first trimester (OR: 1.84; 95% CI: 1.23, 2.74). CONCLUSIONS Unintended pregnancies were associated with current stress and depression, and delayed prenatal care in this sample of low-income women suggesting the importance of identifying high-risk women and tailoring interventions to support women's needs.

Mshanga, N, Martin, H, Petrucka, P
Journal of human nutrition and dietetics : the official journal of the British Dietetic Association. 2019;(5):625-634
Abstract
BACKGROUND Micronutrients comprised of vitamin and mineral nutrients that are needed during pregnancy for foetal growth, development and maturation, as well as for reducing/preventing maternal complications. However, micronutrient-rich foods (vegetables and fruits) are lacking in the Ngorongoro Conservation Area as a result of restrictions on cultivation in conservation areas and the unavailability of vegetables and fruits in local markets. The present study introduced a food basket intervention and assessed the effectiveness of the food baskets with respect to addressing anaemia, vitamin A and iron deficiencies among pregnant Maasai women within the Ngorongoro Conservation Area. METHODS The quasi-experimental study included Misigiyo ward as a control group (provided education only) and Olbalbal ward as an intervention group (provided food baskets and education). The study assessed haemoglobin, serum ferritin and retinol at baseline and during follow-up. Haemoglobin, serum ferritin and retinol were quantitatively (duplicate) measured with HemoCue™ (HemoCue AB, Ängelholm, Sweden), Maglumi 800 (Snibe Diagnostic, Shenzhen, China) and vitamin A enzyme-linked immunosorbent assay, respectively. Dependent and independent t-tests were used to compare the micronutrient blood levels between and within the groups. RESULTS The present study found a statistically significant increase in serum retinol (P < 0.001) in the intervention group compared to the control group; moreover, baseline serum retinol was positively associated with the follow-up serum retinol, whereas baseline haemoglobin and serum ferritin were negatively associated. CONCLUSIONS The food basket intervention holds promise with repect to reducing micronutrient deficiency, especially in communities where micronutrient-rich foods are scarce.

Abstract
OBJECTIVE To evaluate the effectiveness of mobile technology in the appropriate weight gain of pregnant women. MATERIALS AND METHODS A quasi-experimental study. The sample included 117 pregnant women attending health facilities at la Dirección Regional de Salud (Diresa), Callao. Messages were sent to 58 pregnant women who formed the experimental group to improve their lifestyles and assistance to prenatal care (APC), while 59 pregnant women received routine education provided for pregnants. Messages were sent every three days. The nutritional status of the pregnant women was evaluated using the pre gestational BMI at the first visit of the APC. The weight gain was obtained from the difference between pre-gestational weight and weight recorded during the last controls. RESULTS The adequate weight gain was 27.6% of intervened pregnancies and 25.4% in the non-intervened. The 79.3% pregnant had six or more NPC in the group intervened and 54.2% in the non-intervened. The weight gain was excessive in 5.1% in the non-intervened pregnant and 1.7% in the intervened. The highest percentage of pregnant women with adequate weight gain (32.0%) was observed in the intervened pregnancies with pre-gestacional overwhegith. CONCLUSIONS There was no statistic difference in the use of mobile technology for a proper weight gain between both study groups. There were greater fulfillment of APC in intervened pregnancies compared to the non-intervened (p<0.05).

Luo, XD, Dong, X, Zhou, J
Saudi medical journal. 2014;(10):1267-70
Abstract
OBJECTIVES To evaluate whether nutritional management intervention can prevent excessive weight gain during pregnancy and improve perinatal outcomes. METHODS This cross-sectional study included 276 pregnant women undergoing prenatal care between June 2010 and December 2011 at the Obstetrics and Gynecology Department of the Second Affiliate Hospital of the ChongQing University of Medical Sciences, Chongqing, China. Of them, 131 women received individualized nutritional management in addition to routine prenatal care (intervention group), and 145 women received only routine prenatal care (control group). The primary study outcome was gestational weight gain (GWG). Secondary outcomes included birth weight, Apgar score, and incidence of pregnancy complications. RESULTS Baseline demographic characteristics of the 2 groups were the same. The average GWG was higher in the control group (12.57+/-4.62 kg) compared with the intervention group (7.58+/-1.59 kg; p=0.000). The incidence rate of preeclampsia was 3.1% and gestational diabetes was 3.8% for the intervention group, compared with 11% for preeclampsia and 14.5% gestational diabetes for the control group (p<0.05). The incidence rates of premature rupture of membranes, preterm labor, birth weight, birth of a newborn, and major congenital anomalies did not significantly differ between the 2 groups. CONCLUSION Nutritional management intervention prevented excessive GWG and improved perinatal outcomes. These results support the hypothesis that nutritional management intervention can decrease the rate of complications experienced by expecting mothers.

Mustila, T, Raitanen, J, Keskinen, P, Saari, A, Luoto, R
Journal of negative results in biomedicine. 2012;:11
Abstract
BACKGROUND Fetal conditions are known to be partly responsible for the child's risk for obesity. Our pilot study aimed to determine the effect of gestational lifestyle counseling on the offspring weight gain until 4 years of age and to estimate power for future studies. DESIGN AND METHODS First-time pregnant mothers participated in a controlled trial conducted in maternity health clinics during 2004 - 2006. The intervention included individual counseling on physical activity and diet, and an option to attend supervised group exercise sessions. The participant mothers (N = 109) received a follow-up questionnaire concerning 13 repeated growth measurements of their offspring. Response rate to the follow-up questionnaire was 66.1% (N = 72/109). RESULTS The increase of BMI z-score between 24-48 months was not significantly slower among the intervention group offspring (95% CI -0.025 to 0.009, p = 0.34) compared to control group. Z-scores for weight-for-length/height did not differ between groups when the period 0-48 months was analyzed (95% CI -0.010 to 0.014, p = 0.75). CONCLUSIONS In this pilot study gestational lifestyle counseling did not significantly slow the weight gain of the offspring. Gestational intervention studies with at least 300 mothers per group are needed to confirm the possible effect on offspring's risk for obesity.

Abstract
Women with phenylketonuria (PKU) must follow a strict low-phenylalanine diet during pregnancy in order to protect the fetus from the deleterious effects of high maternal blood phenylalanine. The Resource Mothers Study of Maternal PKU was undertaken to determine whether a home visitation programme was effective in helping women with PKU attain blood phenylalanine control earlier during pregnancy. Resource Mothers were trained to provide social support and practical assistance to women with PKU during pregnancy. Eight metabolic clinics in the United States participated in the study. Women with PKU who were planning pregnancy or already pregnant were enrolled in the study and were treated with a low-phenylalanine diet aimed at controlling blood phenylalanine to 120-360 micromol/L. They were randomly assigned to receive the services of a Resource Mother (RM group) or to a control group. Fifty women were enrolled, and accounted for 44 pregnancies which resulted in 28 live births, and 6 spontaneous abortions. Ten women are currently pregnant and another 6 have not become pregnant. Fifty-six percent of enrolled women began the diet prior to becoming pregnant. Fifty-three percent of women in the Resource Mother group were in metabolic control by 10 weeks gestation as compared to 39% in the control group. In addition, women who began diet after pregnancy and had a Resource Mother attained metabolic control earlier (mean gestational age of 22.4 weeks in the RM group vs 29.8 weeks in the control group). There was no difference in birth measurement z -scores of offspring born to women in the RM group compared to controls. All but 4 women rated themselves as feeling worse about the diet at the end of pregnancy than at the beginning, and few women in either group remained on diet after delivery.

Depression and negative life events among pregnant African-American and Hispanic women.
Zayas, LH, Cunningham, M, McKee, MD, Jankowski, KR
Women's health issues : official publication of the Jacobs Institute of Women's Health. 2002;(1):16-22
Abstract
Depression, social support, and life events were assessed in a sample of African-American and Hispanic women (N = 148) with uncomplicated pregnancies. Over half (51%) showed elevated depressive symptoms. Overall, women had fewer social supports and more negative life events than found in previous studies. African-Americans had more practical social support and persons in their support networks than Hispanics. Over a third of the sample (37%) had lost an important person in the past year. Depressed women reported more negative events than nondepressed women. Many negative life events and few social supports place minority women at risk for prenatal depression.
