Impact of Voluntary Folic Acid Fortification of Corn Masa Flour on RBC Folate Concentrations in the U.S. (NHANES 2011-2018).

Surveillance data have highlighted continued disparities in neural tube defects (NTDs) by race-ethnicity in the United States. Starting in 2016, the Food and Drug Administration (FDA) authorized voluntary folic acid fortification of corn masa flour to reduce the risk of neural tube defects (NTDs) among infants of Hispanic women of reproductive age. To assess the impact of voluntary corn masa fortification, cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) 2011-2018 for Hispanic women of reproductive age with available red blood cell (RBC) folate concentrations were analyzed, with additional analyses conducted among Hispanic women whose sole source of folic acid intake was fortified foods (enriched cereal grain products (ECGP) only), excluding ready-to-eat cereals and supplements. RBC folate concentration (adjusted geometric mean) among Hispanic women of reproductive age did not differ between 2011-2016 and 2017-2018, though RBC folate concentration increased significantly among lesser acculturated Hispanic women consuming ECGP only. Concentrations of RBC folate for those born outside the U.S and residing in the U.S <15 years increased from 894 nmol/L (95% CI: 844-946) in 2011-2016 to 1018 nmol/L (95% CI: 982-1162; p < 0.001) in 2017-2018. Primarily Spanish-speaking Hispanic women of reproductive age who only consumed ECGP saw an increase from 941 nmol/L (95% CI: 895-990) in 2011-2016 to 1034 nmol/L (95% CI: 966-1107; p = 0.03) in 2017-2018. By subpopulation, we observed no significant changes in the proportion at risk of NTDs (<748 nmol/L) and no changes in the model-based estimated NTD rates following voluntary corn masa fortification. This analysis suggests that there is a remaining risk among Hispanics for folate sensitive NTDs, though continued monitoring of folate status in future NHANES data cycles will help inform the long-term efficacy of voluntary fortification of corn masa flour.

Using a cultural-ecological framework to explore dietary beliefs and practices during pregnancy and lactation among women in Adivasi communities in the Nilgiris Biosphere Reserve, India.

This article explores maternal dietary beliefs and practices gathered through interviews with mothers of infants and young children in Adivasi communities in the Nilgiris Biosphere Reserve, India. Guided by focused ethnographic study methods, interviews were conducted with 33 key informants. We used a cultural-ecological framework to analyze and interpret the texts that were elicited from women about dietary beliefs and eating patterns during pregnancy and lactation. We identify differences between what women were advised to eat, felt they should eat, and reported consuming. The findings offer guidance for interventions to improve maternal diets in this vulnerable population.

Local foods can meet micronutrient needs for women in urban Burkina Faso, but only if rarely consumed micronutrient-dense foods are included in daily diets: A linear programming exercise.

Women of reproductive age are at nutritional risk due to their need for nutrient-dense diets. Risk is further elevated in resource-poor environments. In one such environment, we evaluated feasibility of meeting micronutrient needs of women of reproductive age using local foods alone or using local foods and supplements, while minimizing cost. Based on dietary recall data from Ouagadougou, we used linear programming to identify the lowest cost options for meeting 10 micronutrient intake recommendations, while also meeting energy needs and following an acceptable macronutrient intake pattern. We modeled scenarios with maximum intake per food item constrained at the 75th percentile of reported intake and also with more liberal maxima based on recommended portions per day, with and without the addition of supplements. Some scenarios allowed only commonly consumed foods (reported on at least 10% of recall days). We modeled separately for pregnant, lactating, and nonpregnant, nonlactating women. With maxima constrained to the 75th percentile, all micronutrient needs could be met with local foods but only when several nutrient-dense but rarely consumed items were included in daily diets. When only commonly consumed foods were allowed, micronutrient needs could not be met without supplements. When larger amounts of common animal-source foods were allowed, all needs could be met for nonpregnant, nonlactating women but not for pregnant or lactating women, without supplements. We conclude that locally available foods could meet micronutrient needs but that to achieve this, strategies would be needed to increase consistent availability in markets, consistent economic access, and demand.

Association between pre-pregnancy consumption of meat, iron intake, and the risk of gestational diabetes: the SUN project.

PURPOSE: We assessed the association of total meat, processed, and unprocessed red meat and iron intake with the risk of developing gestational diabetes mellitus (GDM) in pregnant women. METHODS: We conducted a prospective study among 3298 disease-free Spanish women participants of the SUN cohort who reported at least one pregnancy between December 1999 and March 2012. Meat consumption and iron intake were assessed at baseline through a validated, 136-item semi-quantitative, food frequency questionnaire. We categorized total, red, and processed meat consumption and iron intake into quartiles. Logistic regression models were used to adjust for potential confounders. RESULTS: We identified 172 incident cases of GDM. In the fully adjusted analysis, total meat consumption was significantly associated with a higher risk of GDM [OR = 1.67 (95% CI 1.06-2.63, p-trend 0.010)] for the highest versus the lowest quartile of consumption. The observed associations were particularly strong for red meat consumption [OR = 2.37 (95% CI 1.49-3.78, p-trend < 0.001)] and processed meat consumption [OR = 2.01 (95% CI 1.26-3.21, p-trend 0.003)]. Heme iron intake was also directly associated with GDM [OR = 2.21 (95% CI 1.37-3.58, p-trend 0.003)], although the association was attenuated and lost its statistical significance when we adjusted for red meat consumption [OR = 1.57 (95% CI 0.91-2.70, p-trend 0.213)]. No association was observed for non-heme and total iron intake, including supplements. CONCLUSIONS: Our overall findings suggest that higher pre-pregnancy consumption of total meat, especially red and processed meat, and heme iron intake, are significantly associated with an increased GDM risk in a Mediterranean cohort of university graduates.

Concurrent iron and zinc deficiencies in lactating mothers and their children 6-23 months of age in two agro-ecological zones of rural Ethiopia.

PURPOSE: The aim of this study is to examine the co-occurrences of low serum ferritin and zinc and anaemia among mothers and their children in two agro-ecological zones of rural Ethiopia. METHODS: Data were collected from 162 lactating mothers and their breast fed children aged 6-23 months. The data were collected via a structured interview, anthropometric measurements, and blood tests for zinc, ferritin and anaemia. Correlation, Chi-square and multivariable analysis were used to determine the association between nutritional status of mothers and children, and agro-ecological zones. RESULTS: Low serum levels of iron and zinc, anaemia and iron deficiency anaemia were found in 44.4, 72.2, 52.5 and 29.6% of children and 19.8, 67.3, 21.8, 10.5% of mothers, respectively. There was a strong correlation between the micronutrient status of the mothers and the children for ferritin, zinc and anaemia (p < 0.005). Deficiency in both zinc and ferritin and one of the two was observed in 19.1, and 53.7% of the mothers and 32.7 and 46.3%, of their children, respectively. In the 24 h before the survey, 82.1% of mothers and 91.9% of their infants consumed foods that can decrease zinc bioavailability while only 2.5% of mothers and 3.7% of their infants consumed flesh foods. CONCLUSION: This study shows that micronutrient deficiencies were prevalent among lactating mothers and their children, with variation in prevalence across the agro-ecological zones. This finding calls for a need to design effective preventive public health nutrition programs to address both the mothers' and their children's needs.

Erythrocyte fatty acid composition of Nepal breast-fed infants.

PURPOSE: Essential fatty acids play a critical role in the growth and development of infants, but little is known about the fatty acid status of populations in low-income countries. The objective was to describe the fatty acid composition of red blood cells (RBC) in breastfeed Nepali infants and a subsample of their mothers and to identify the main sources of fatty acids in the mother's diet, as well as the fatty acid composition of breast milk. METHODS: RBC fatty acid composition was analyzed in a random sample of 303 infants and 72 mother, along with 68 breastmilk samples. Fatty acid profiles of the most important dietary fat sources were analyzed. Information on mother's diet and intake of fat was collected by three 24-h dietary recalls. RESULTS: In infant RBC's, docosahexaenoic acid (DHA) was the main n-3 fatty acid, and arachidonic acid (AA) was the major n-6 fatty acid. Total n-6 PUFA was three times higher than total n-3 PUFA. Height-for-age (HAZ) was positively associated with DHA status and AA status in multivariable models. The concentration of all fatty acids was higher in children, compared to mothers, except Total n-6 PUFA and Linoleic acid (LA) where no differences were found. The mother's energy intake from fat was 13% and cooking oil (sesame, mustard, soybean or sunflower oil) contributed 52% of the fat intake. CONCLUSIONS: RBC-DHA levels in both infants and mother was unexpected high taking into account few dietary DHA sources and the low DHA concentrations in breastmilk.

Dietary intake and biomarker status of folate in Swedish adults.

PURPOSE: National data on folate status are missing in Sweden, and regional data indicate folate insufficiency in up to more than 25% of the study populations. The objectives were to determine folate intake and status in the adult Swedish population as well as identifying dietary patterns associated with beneficial folate status. METHODS: Folate intake was estimated using a web-based 4-d food record in adults aged 18-80 years (n = 1797). Folate status was measured as erythrocyte (n = 282) and plasma folate concentrations (n = 294). Factor analysis was used to derive a dietary pattern associated with a higher folate status. RESULTS: Median folate intake was 246 µg/day (Q 1 = 196, Q 3 = 304, n = 1797) and for women of reproductive age 227 µg/day (Q 1 = 181, Q 3 = 282, n = 450). As dietary folate equivalents (DFE), median intake was 257 µg/day (Q 1 = 201, Q 3 = 323) and for women of reproductive age 239 µg/day (Q 1 = 185, Q 3 = 300). Low blood folate concentrations were found in 2% (erythrocyte concentrations <317 nmol/L) and 4% (plasma concentrations <6.8 nmol/L) of the participants, respectively. None of the women of reproductive age had erythrocyte folate concentrations associated with the lowest risk of neural tube defects. Dietary patterns associated with higher folate status were rich in vegetables, pulses and roots as well as cheese and alcoholic beverages, and low in meat. CONCLUSIONS: Prevalence of low erythrocyte folate concentrations was low in this population, and estimated dietary intakes are well above average requirement. However, to obtain a folate status optimal for prevention of neural tube defects major dietary changes are required and folic acid supplements recommended prior to conception.

Program considerations for integration of nutrition and family planning: Beliefs around maternal diet and breastfeeding within the context of the nutrition transition in Egypt.

In Egypt, rising maternal overweight and obesity is consistent with the transition to westernized diets and a growing reliance on energy-dense, low nutrient foods. Although the first 1,000 days of life are the focus of many programmes designed to prevent many forms of malnutrition, little attention has been paid to maternal dietary practices and weight gain during pregnancy. This study used in-depth interviews with pregnant women (N = 40), lactating women (N = 40), and nonlactating women (N = 40) to gain an understanding of behaviours, perceptions, and cultural beliefs in relation to maternal dietary intake during pregnancy, lactation, and nonlactation; weight gain during pregnancy; birth spacing; and family planning. Study findings reveal that food choice was driven by affordability, favoured foods, or foods considered appropriate for a specific life stage (pregnant, lactating, and nonlactating). Knowledge of weight gain during pregnancy is limited, especially with regards to excessive weight gain during pregnancy. Diet is often modified during lactation to support breast milk production, and a normal diet resumed when breastfeeding ceases. Within the context of breastfeeding, the lactational amenorrhea method provides an opportunity to improve exclusive breastfeeding practices, maternal diet during lactation, and the transition to other family planning methods by 6 months postpartum. Health care providers should discuss limiting maternal consumption of low nutrient foods such as junk foods, soda, and teas during pregnancy and postpartum. Dietary counselling should accompany information on appropriate weight gain during pregnancy and exercise to prevent excessive weight gain, in the context of the nutrition transition.

Suboptimal maternal and cord plasma pyridoxal 5' phosphate concentrations are uncommon in a cohort of Canadian pregnant women and newborn infants.

Vitamin B6 is important in fetal development, but little is known of the vitamin B6 status of pregnant women and newborns in North America and potential modifying factors. This prospective study determined maternal and cord plasma concentrations of pyridoxal 5' phosphate (PLP; an indicator of vitamin B6 status) in a convenience sample of 368 Canadian pregnant women and their newborns. The association of maternal intake of vitamin B6 and fetal genetic variants with cord plasma PLP and homocysteine concentrations was also examined. Dietary and supplemental intakes of vitamin B6 were assessed in early and mid to late pregnancy. PLP concentrations were measured in maternal plasma in early pregnancy and at delivery, and in cord plasma. Six fetal variants of the MTHFR and CßS genes were assessed for their association with cord plasma PLP and homocysteine concentrations. Geometric mean (95% CI) PLP concentrations were 107 (98, 116) nmol/L in early pregnancy and 58 (53, 62) nmol/L at delivery, respectively, and 296 (275, 319) nmol/L in cord blood (p < .0001). During early pregnancy and at delivery, 3.6% and 5.5% of women had plasma PLP concentrations <20 nmol/L, respectively. Ninety eight percent of the women with supplemental B6 intake of at least the recommended dietary allowance had PLP concentrations >20 nmol/L. Fetal genetic variants were not associated with cord PLP and homocysteine concentrations. Vitamin B6 deficiency is uncommon in a cohort of Canadian pregnant women due largely to prevalent vitamin B6 supplement use.

Partnering with women collectives for delivering essential women's nutrition interventions in tribal areas of eastern India: a scoping study.

BACKGROUND: We examined the feasibility of engaging women collectives in delivering a package of women's nutrition messages/services as a funded stakeholder in three tribal-dominated districts of Odisha, Jharkhand and Chhattisgarh States, in eastern India. These districts have high prevalence of child stunting and poor government service outreach. METHODS: Conducted between July 2014 and March 2015, an exploratory mix-methods design was adopted (review of coverage data and government reports, field interviews and focus group discussion with multiple stakeholders and intended communities) to assess coverage of women's nutrition services. A capacity assessment tool was developed to map all types of community collectives and assess their awareness, institutional and programme capacity as a funded stakeholder for delivering women's nutrition services/behaviour promotion. RESULTS: Limited targeting of pre-pregnancy period, delays in first trimester registration of pregnant women, and low micronutrient supplementation supply and awareness issues emerged as key bottlenecks in improving women's nutrition in these districts. Amongst the 18 different types of community collectives mapped, Self Help Groups (SHGs) and their federations (tier 2 and tier 3), with total membership of over 650,000, emerged as the most promising community collective due to their vast network, governance structure, bank linkage, and regular interface. Nearly 400,000 (or 20% of women) in these districts can be reached through the mapped 31,919 SHGs. SHGs with organisational readiness for receiving and managing grants for income generation and community development activities varied from 41 to 94% across study districts. Stakeholders perceived that SHGs federations managing grants from government and be engaged for nutrition promotion and service delivery and SHG weekly meetings can serve as community interface for discussing/resolving local issues impeding access to services. CONCLUSIONS: Women SHGs (with tier 2 and tier 3) can become direct grantees for strengthening coverage of women's nutrition interventions in these tribal districts/pockets, provided they are capacitated, supervised and given safe guards against exploitation and violence.

Small-quantity, lipid-based nutrient supplements provided to women during pregnancy and 6 mo postpartum and to their infants from 6 mo of age increase the mean attained length of 18-mo-old children in semi-urban Ghana: a randomized controlled trial.

BACKGROUND: Childhood stunting usually begins in utero and continues after birth; therefore, its reduction must involve actions across different stages of early life. OBJECTIVE: We evaluated the efficacy of small-quantity, lipid-based nutrient supplements (SQ-LNSs) provided during pregnancy, lactation, and infancy on attained size by 18 mo of age. DESIGN: In this partially double-blind, individually randomized trial, 1320 women at ≤20 wk of gestation received standard iron and folic acid (IFA group), multiple micronutrients (MMN group), or SQ-LNS (LNS group) daily until delivery, and then placebo, MMNs, or SQ-LNS, respectively, for 6 mo postpartum; infants in the LNS group received SQ-LNS formulated for infants from 6 to 18 mo of age (endline). The primary outcome was child length by 18 mo of age. RESULTS: At endline, data were available for 85% of 1228 infants enrolled; overall mean length and length-for-age z score (LAZ) were 79.3 cm and -0.83, respectively, and 12% of the children were stunted (LAZ <-2). In analysis based on the intended treatment, mean ± SD length and LAZ for the LNS group (79.7 ± 2.9 cm and -0.69 ± 1.01, respectively) were significantly greater than for the IFA (79.1 ± 2.9 cm and -0.87 ± 0.99) and MMN (79.1 ± 2.9 cm and -0.91 ± 1.01) groups (P = 0.006 and P = 0.009, respectively). Differences were also significant for weight and weight-for-age z score but not head or midupper arm circumference, and the prevalence of stunting in the LNS group was 8.9%, compared with 13.7% in the IFA group and 12.9% in the MMN group (P = 0.12). In analysis based on actual supplement provided at enrollment, stunting prevalences were 8.9% compared with 15.1% and 11.5%, respectively (P = 0.045). CONCLUSION: Provision of SQ-LNSs to women from pregnancy to 6 mo postpartum and to their infants from 6 to 18 mo of age may increase the child's attained length by age 18 mo in similar settings. This trial was registered at clinicaltrials.gov as NCT00970866.

Maternal Methyl-Group Donor Intake and Global DNA (Hydroxy)Methylation before and during Pregnancy.

It is still unclear to which extent methyl-group intake during pregnancy can affect maternal global DNA (hydroxyl)methylation. Pregnancy methylation profiling and its link with methyl-group intake in a healthy population could enhance our understanding of the development of pregnancy related disorders. One hundred forty-eight women were enrolled in the MANOE (MAternal Nutrition and Offspring's Epigenome) study. Thiry-four women were enrolled before pregnancy and 116 during the first trimester of pregnancy. Global DNA (hydroxy)methylation in blood using LC-MS/MS and dietary methyl-group intake (methionine, folate, betaine, and choline) using a food-frequency questionnaire were estimated pre-pregnancy, during each trimester, and at delivery. Global DNA (hydroxy)methylation levels were highest pre-pregnancy and at weeks 18-22 of pregnancy. We observed a positive relation between folic acid and global DNA methylation (p = 0.04) and hydroxymethylation (p = 0.04). A high intake of methionine pre-pregnancy and in the first trimester showed lower (hydroxy)methylation percentage in weeks 11-13 and weeks 18-22, respectively. Choline and betaine intake in the first weeks was negatively associated with hydroxymethylation. Women with a high intake of these three methyl groups in the second and third trimester showed higher hyrdoxymethylation/methylation levels in the third trimester. To conclude, a time trend in DNA (hydroxy)methylation was found and women with higher methyl-group intake showed higher methylation in the third trimester, and not in earlier phases of pregnancy.

Relationship between polyunsaturated fatty acid levels in maternal diets and human milk in the first month post-partum.

BACKGROUND: The present study evaluated the relationship between dietary fatty acid (FA) intakes and human milk FA levels. METHODS: Healthy lactating women (n = 514) from Northern China participated in the study. Dietary intake was assessed with a 24-h dietary recall questionnaire and evaluated using golden key maternal nutrition software (Wincome, Shanghai, China) and China Food Composition 2009. Human milk FA composition was determined by gas chromatography. RESULTS: The maternal daily median intakes of linoleic acid (LA), α-linolenic acid (ALA) and arachidonic acid (AA) were 19.93 g, 3.08 g and 16.33 mg, respectively. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) intakes were below the recommended levels. FA levels in 100 g of human milk were 0.363 g LA, 0.038 g γ-linolenic acid (GLA), 0.052 g dihomo γ-linolenic acid (DGLA), 0.144 g ALA, 0.079 g AA, 0.007 g EPA, 0.018 g docosatetraenoic acid (DTA) and 0.048 g DHA. Multiple linear regression analysis revealed that human milk DGLA levels were negatively correlated with dietary LA intake (ß = -0.223, P = 0.030), and human milk GLA and DTA levels were negatively correlated with dietary ALA intake (ß = -2.189, P = 0.031; ß = -2.252, P = 0.027) after adjusting for possible confounding factors. CONCLUSIONS: The results of the present study suggest the presence of competitive interactions between n-3 fatty acids (ALA) and n-6 fatty acids (GLA and DTA).

The iodized salt programme in Bangalore, India provides adequate iodine intakes in pregnant women and more-than-adequate iodine intakes in their children.

OBJECTIVE: To compare the iodine status of pregnant women and their children who were sharing all meals in Bangalore, India. DESIGN: A cross-sectional study evaluating demographic characteristics, household salt iodine concentration and salt usage patterns, urinary iodine concentrations (UIC) in women and children, and maternal thyroid volume (ultrasound). SETTING: Antenatal clinic of an urban tertiary-care hospital, which serves a low-income population. SUBJECTS: Healthy pregnant women in all trimesters, aged 18-35 years, who had healthy children aged 3-15 years. RESULTS: Median (range) iodine concentrations of household powdered and crystal salt were 55·9 (17·2-65·9) ppm and 18·9 (2·2-68·2) ppm, respectively. The contribution of iodine-containing supplements and multi-micronutrient powders to iodine intake in the families was negligible. Adequately iodized salt, together with small amounts of iodine in local foods, were providing adequate iodine during pregnancy: (i) the overall median (range) UIC in women was 172 (5-1024) µg/l; (ii) the median UIC was >150 µg/l in all trimesters; and (iii) thyroid size was not significantly different across trimesters. At the same time, the median (range) UIC in children was 220 (10-782) µg/l, indicating more-than-adequate iodine intake at this age. Median UIC was significantly higher in children than in their mothers (P=0·008). CONCLUSIONS: In this selected urban population of southern India, the iodized salt programme provides adequate iodine to women throughout pregnancy, at the expense of higher iodine intake in their children. Thus we suggest that the current cut-off for median UIC in children indicating more-than-adequate intake, recommended by the WHO/UNICEF/International Council for the Control of Iodine Deficiency Disorders may, need to be reconsidered.

Iron deficiency is uncommon among lactating women in urban Nepal, despite a high risk of inadequate dietary iron intake.

The main objective of the present study was to examine the association between dietary Fe intake and dietary predictors of Fe status and Hb concentration among lactating women in Bhaktapur, Nepal. We included 500 randomly selected lactating women in a cross-sectional survey. Dietary information was obtained through three interactive 24 h recall interviews including personal recipes. Concentrations of Hb and plasma ferritin and soluble transferrin receptors were measured. The daily median Fe intake from food was 17·5 mg, and 70% of the women were found to be at the risk of inadequate dietary Fe intake. Approximately 90% of the women had taken Fe supplements in pregnancy. The prevalence of anaemia was 20% (Hb levels < 123 g/l) and that of Fe deficiency was 5% (plasma ferritin levels < 15 µg/l). In multiple regression analyses, there was a weak positive association between dietary Fe intake and body Fe (ß 0·03, 95% CI 0·014, 0·045). Among the women with children aged < 6 months, but not those with older infants, intake of Fe supplements in pregnancy for at least 6 months was positively associated with body Fe (P for interaction < 0·01). Due to a relatively high dietary intake of non-haem Fe combined with low bioavailability, a high proportion of the women in the present study were at the risk of inadequate intake of Fe. The low prevalence of anaemia and Fe deficiency may be explained by the majority of the women consuming Fe supplements in pregnancy.

Racial/ethnic and sociodemographic factors associated with micronutrient intakes and inadequacies among pregnant women in an urban US population.

OBJECTIVE: To assess sociodemographic correlates of micronutrient intakes from food and dietary supplements in an urban, ethnically diverse sample of pregnant women in the USA. DESIGN: Cross-sectional analyses of data collected using a validated semi-quantitative FFQ. Associations between racial, ethnic and sociodemographic factors and micronutrient intakes were examined using logistic regression controlling for pre-pregnancy BMI, maternal age and smoking status. SETTING: Prenatal clinics, Boston, MA, USA. SUBJECTS: Analyses included pregnant women (n 274) in the PRogramming of Intergenerational Stress Mechanisms (PRISM) study, an urban longitudinal cohort designed to examine how stress influences respiratory health in children when controlling for other environmental exposures (chemical stressors, nutrition). RESULTS: High frequencies of vitamin E (52 %), Mg (38 %), Fe (57 %) and vitamin D (77 %) inadequacies as well as suboptimal intakes of choline (95 %) and K (99 %) were observed. Factors associated with multiple antioxidant inadequacies included being Hispanic or African American, lower education and self-reported economic-related food insecurity. Hispanics had a higher prevalence of multiple methyl-nutrient inadequacies compared with African Americans; both had suboptimal betaine intakes and higher odds for vitamin B6 and Fe inadequacies compared with Caucasians. Nearly all women (98 %) reported Na intakes above the tolerable upper limit; excessive intakes of Mg (35 %), folate (37 %) and niacin (38 %) were also observed. Women reporting excessive intakes of these nutrients were more likely Caucasian or Hispanic, more highly educated, US-born and did not report food insecurity. CONCLUSIONS: Racial/ethnic and other sociodemographic factors should be considered when tailoring periconceptional dietary interventions for urban ethnic women in the USA.

Dietary changes during pregnancy and the postpartum period in Singaporean Chinese, Malay and Indian women: the GUSTO birth cohort study.

OBJECTIVE: To examine changes in food consumption during pregnancy and the postpartum period in women of major Asian ethnic groups. DESIGN: Using interviewer-administered questionnaires, we assessed changes in food consumption during pregnancy (26-28 weeks' gestation) and the postpartum period (3 weeks after delivery) as compared with the usual pre-pregnancy diet. SETTING: Singapore. SUBJECTS: Pregnant women (n 1027) of Chinese, Malay and Indian ethnicity (mean age 30·4 (SD 5·2) years) who participated in the Growing Up in Singapore Towards healthy Outcomes (GUSTO) study. RESULTS: During pregnancy, participants tended to increase their consumption of milk, fruit and vegetables and decrease their consumption of tea, coffee, soft drinks and seafood (all P < 0·001). Most participants reported adherence to traditional restrictions ('confinement') during the early postpartum period (Chinese: 94·8 %, Malay: 91·6 %, Indian: 79·6 %). During the postpartum period, participants tended to increase their consumption of fish and milk-based drinks and decrease their consumption of noodles, seafood, and chocolates and sweets (all P < 0·001). Ethnic differences in food consumption were pronounced during the postpartum period. For example, most Chinese participants (87·2 %) increased their ginger consumption during the postpartum period as compared with smaller percentages of Malays (31·8 %) and Indians (40·8 %; P for ethnic difference <0·001). Similar ethnic differences were observed for cooking wine/alcohol, herbs and spices, and herbal tea consumption. CONCLUSIONS: Marked changes in food consumption that reflect both modern dietary recommendations and the persistence of traditional beliefs were observed in Singaporean women during pregnancy and the postpartum period. Traditional beliefs should be considered in interventions to improve dietary intakes during these periods.

Antenatal calcium intake in Malaysia.

AIM: To determine the adequacy of antenatal calcium intake in Malaysia, and the influencing factors. METHODS: A cross-sectional study was conducted among postnatal women who delivered in two tertiary hospitals. Data were collected from antenatal cards, hospital documents and diet recall on daily milk and calcium intake during pregnancy. SPSS version 19.0 was used for statistical analyses. RESULTS: A total of 150 women were studied. The total daily calcium intake was 834 ± 43 mg (mean ± standard error of the mean), but the calcium intake distribution curve was skewed to the right with a median intake of 725 mg daily. When calcium intake from milk and calcium supplements was excluded, the daily dietary calcium intake was only 478 ± 25 mg. Even with inclusion of milk and calcium supplements, more than a third (n=55 or 36.7%) of the women consumed less than 600 mg calcium in their daily diet. The adequacy of daily calcium intake was not influenced by maternal age, ethnicity, income or maternal job or educational status as well as parity. CONCLUSION: The daily dietary calcium intake of the Malaysian antenatal population is far from adequate without the addition of calcium supplements and milk.

Prevalence and public health relevance of micronutrient deficiencies and undernutrition in pre-school children and women of reproductive age in Côte d'Ivoire, West Africa.

OBJECTIVE: To provide nationally representative data on the prevalence of anaemia, vitamin A and Fe deficiencies among pre-school age children (pre-SAC) and non-pregnant women of reproductive age (WRA), and on vitamin B12 and folate deficiencies in WRA, and the influence of inflammation on their interpretation. DESIGN: A cross-sectional survey to measure anthropometry, malaria parasitaemia and micronutrient status. Specifically, blood samples were analysed for Hb, plasma ferritin, soluble transferrin receptors, C-reactive protein, α1-acid glycoprotein, retinol-binding protein, vitamin B12 and folate. SETTING: Côte d'Ivoire in 2007. SUBJECTS: Nine hundred and twenty-eight WRA and 879 pre-SAC. RESULTS: In WRA, prevalence of Plasmodium parasitaemia (5 %) was low, but inflammation (34 %) was higher. Anaemia was a severe public health problem and prevalence differed by residency and eco-region. Inflammation-adjusted Fe deficiency was highest in urban areas (20 %). Nationally, folate deficiency was 86 %, higher in urban areas and varied by eco-region. Prevalence of vitamin B12 deficiency was low but higher in the rural areas and the north. Inflammation-adjusted vitamin A deficiency was very low (1 %). In pre-SAC, prevalence of inflammation (67 %) and Plasmodium parasites (25 %) was high; the latter was associated with poverty, rural residency and higher ferritin concentrations. Anaemia was classified as a severe public health problem (72 %), and was higher in rural areas (76 %) and the north (87 %). A quarter of pre-SAC suffered from vitamin A deficiency (inflammation-adjusted) and prevalence of undernutrition was high. CONCLUSIONS: Prevalence of inflammation, Plasmodium parasitaemia and micronutrient deficiencies were high in Côte d'Ivoire, particularly in pre-SAC. Nutritional interventions should be accompanied by strategies to reduce exposure to infections.

Factors associated with not using folic acid supplements preconceptionally.

OBJECTIVE: Neural tube defects are among the most common birth defects worldwide. Folic acid intake from one month before to three months after conception reduces the likelihood of neural tube defects by at least 50%. Since 1995, several campaigns have been organised in the Netherlands which resulted in 51% of pregnant women using folic acid supplements during the entire recommended period in the northern part of the Netherlands in 2005. Our research question was to gain insight into the current prevalence and factors associated with inadequate pregnancy-related use of folic acid supplements. DESIGN: Data from the DELIVER study were used, which is a population-based cohort study. SETTING: Twenty midwifery practices across the Netherlands in 2009 and 2010. SUBJECTS: In total 5975 pregnant women completed a questionnaire covering items on sociodemographic and lifestyle factors, including folic acid intake. RESULTS: Of our study population, 55·5% (3318/5975) used folic acid supplements before conception. Several sociodemographic and lifestyle factors were associated with no preconception use of folic acid, of which non-Western ethnicity and not having a partner had the largest effect size. CONCLUSIONS: In the Netherlands, the folic acid intake before conception is suboptimal and has not improved over recent years. Fortification of staple foods with folic acid should be reconsidered as it would provide a more effective means of ensuring an adequate intake, especially for those groups of women who are unlikely to plan their pregnancies or to receive or respond to health promotion messages.
