Acceptability of 11 fortified balanced energy‐protein supplements for pregnant women in Nepal

Evidence suggests that multiple micronutrient and balanced energy protein (BEP) supplementation during pregnancy can decrease the risk of stillbirth and small‐for‐gestational‐age births and increase birth weight. We conducted a mixed‐methods formative research study to identify the most acceptable among a range of 11 candidates fortified BEP supplements for use in pregnancy and lactation in a rural district in Nepal. Forty pregnant women aged 15–40 years participated in a test meal tasting of 11 different sweet and savoury candidate BEP supplements. Each participant rated the products on organoleptic properties using a 7‐point hedonic scale (1 = Dislike it very much to 7 = Like it very much), ranked her ‘top 3’ most liked supplements, and subsequently discussed each product with peers in focus group discussions (FGDs). Five supplements (sweet lipid‐based nutrient supplement (LNS), savoury LNS, sweet vanilla biscuits, vanilla instant drinks and seasoned pillows) achieved the maximum overall median hedonic score of 7, with sweet LNS and seasoned pillows ranking as the top 2. This was consistent with the assessments in FGDs. Women in the FGDs expressed dislike of the smell and taste of the cocoa drink, savoury masala bar, sweet mango bar and savoury curry biscuit, which was consistent with the hedonic scale scores. This study provides valuable insights into our understanding of women''s acceptance of different BEP supplements during pregnancy in rural Nepal and has helped identify the two most accepted BEP supplements to be used in a two‐month home trial to assess utilisation and compliance in this setting.     

Home consumption of two fortified balanced energy protein supplements by pregnant women in Burkina Faso

Balanced energy protein (BEP) supplementation for pregnant and lactating women in low‐ and middle‐income countries is a promising strategy to improve birth outcomes and child growth. The objective of this study was to assess and compare the acceptability of new formulations of two fortified BEP supplements, a lipid‐based peanut paste and a vanilla biscuit, among 80 pregnant women in rural Burkina Faso, prior to an efficacy trial. A 10‐week individually randomized cross‐over study was designed, in which women received a weekly supply of each supplement for 4 weeks, and a daily choice between the supplements in the last 2 weeks. Questionnaires to assess daily consumption and supplement acceptability (n = 80) and home observations (n = 20) were combined with focus group discussions (n = 6) and in‐depth interviews with women (n = 80) and stakeholders (n = 24). Results showed that the two supplements were well accepted. Quantitative findings indicated high compliance (>99.6%) and high overall appreciation (Likert score >6 out of 7) of both supplements. The assessment of preferred choice in Weeks 9 and 10 indicated a slight preference for the vanilla biscuit. Qualitative findings indicated that perceived health benefits, support from household members and educational messages from health professionals were important drivers for acceptance and compliance. Sharing was not often reported but was identified during interviews as a possible risk. We recommend that future studies use a combination of methods to identify appropriate food supplements and context‐specific factors that influence acceptability, compliance and subsequent impact of nutritious food supplements.     

Acceptability of lipid-based nutrient supplements (LNS) among Ghanaian infants and pregnant or lactating women

Inadequate micronutrient intake during pregnancy, lactation and infancy is a major problem in many developing countries. Lipid-based nutrient supplements (LNS) can improve micronutrient status, growth and development of infants, and also have potential to improve nutritional status of pregnant and lactating women. The objective of the study was to test the acceptability of LNS designed for infants (LNS-20gM) and pregnant or lactating women (LNS-P&L). Participants were infants (n = 22, mean age = 8 months) and pregnant or lactating women (n = 24) attending routine services at a hospital in Ghana. Infants consumed 45 g of a test meal consisting of one part LNS-20gM and three parts fermented maize porridge, while women consumed 50 g of a similar test meal containing LNS-P&L instead. Participants also used their respective LNS at home for 14 days. Primary outcome was the proportion of the test meal consumed. On average, infants consumed 76.2% of the test meal [95% (confidence interval) CI: 65.7, 86.7], while women consumed 87.1% (95% CI: 82.6, 91.6). During the 14-day period, median daily consumption of LNS-20gM was 19.3 g, very close to the recommended 20 g d(-1), while that of LNS-P&L was one sachet, as recommended. We conclude that LNS-20gM and LNS-P&L were well accepted.     

Dietary aspects of pregnant women in rural areas of Northern India

The aim of this article is to document the current dietary profile of pregnant women in rural areas of Delhi. In order to explore the diet the combination of quantitative (24-h recall method) and qualitative methods (food frequency method) were used. The mean intake of macronutrients and micronutrients, namely, iron, folic acid and Vitamin C which play an important role in the pathophysiology of nutritional anaemia during pregnancy was calculated from the foodstuffs, using Nutritive Value of Indian Foods. The preferences and avoidance of various foods by the pregnant women were also elicited. The data were analysed using Epi Info 3.4. The intake of calories, protein, iron, folic acid and Vitamin C was found to be less than the recommended dietary allowance in 100%, 91.2%, 98.2%, 99.1% and 65.8% of pregnant women respectively. Folic acid intakes were significantly lower in younger, primiparous and poorly educated women from low-income families. Vitamin C intake was lower among non-Hindus only. The overall data suggested the presence of food gap rather than isolated deficiency of any particular nutrient.     

Burden and determinants of undernutrition among young pregnant women in Ethiopia

Undernutrition is a major public health concern due to its association with the mortality and disease burden of women and children. This study aimed at identifying the extent and determinants of undernutrition among young pregnant women in Ethiopia. A multivariable regression analysis was fitted to identify determinants of undernutrition and anaemia in a sample of 1,393 pregnant women. Risk ratios (RRs) with 95% confidence interval (CI) were estimated. All the analyses were performed using STATA version 14 and adjusted for clustering. The study revealed that 38% of the women were undernourished and 22% were anaemic. Improved maternal education, RR = 0.94, 95% CI [0.89, 0.98]; higher wealth status, RR = 0.72, 95% CI [0.47, 0.95]; higher minimum dietary diversity for women, RR = 0.87, 95% CI [0.77, 0.98]; increased maternal height, RR = 0.96, 95% CI [0.94, 0.98]; and protected water source, RR = 0.93, 95% CI [0.86, 0.96], have decreased the risk of undernutrition while using unimproved toilet, RR = 1.31, 95% CI [1.06, 1.63], and depression, RR = 1.33, 95% CI [1.14, 1.55], increased the risk of anaemia. Animal source food consumption decreased both the risk of undernutrition, RR = 0.85, 95% CI [0.77, 0.94], and anaemia, RR = 0.91, 95% CI [0.85, 0.95]. The burden of undernutrition is still high. Although improved socio‐economic status and dietary practices decreased the risk of undernutrition, poor health and environmental conditions were still significant risk factors. These findings suggest the need to target this set of important determinants to significantly decrease the burden of undernutrition among young pregnant women.     

Seroepidemiological survey of cytomegalovirus infection among pregnant women in Nagasaki,Japan

Background: Epidemiology of cytomegalovirus (CMV) infection varies widely, depending on ethnicity and socioeconomic status. A seroepidemiological survey was conducted to determine CMV infection among pregnant women in Nagasaki Prefecture, Japan. Methods: We measured serum CMV‐specific immunoglobulin (Ig) M and IgG at the first and third trimesters. IgG avidity was determined when both CMV‐IgG and CMV‐IgM were positive. Results: Of 339 pregnant women, 296 (87.3%) were CMV‐IgG‐positive at the first trimester. Of 267 paired sera, one (0.37%) had CMV‐IgG seroconversion, another one (0.37%) had CMV‐IgM seroconversion, and 12 had both CMV‐IgG and CMV‐IgM, two (0.75%) of whom had low IgG avidity, suggesting recent infection. Thus, the incidence of primary CMV infection during pregnancy was 0.74–1.5%. Assuming the rate of in utero transmission following maternal primary infection to be approximately 40%, the incidence of congenital infection is estimated to be 0.3–0.6%. Conclusion: Although CMV seroprevalence among pregnant women has been decreasing in industrialized regions including other parts of Japan, CMV‐seroprevalence remains high in Nagasaki. Thus, epidemiology of CMV infection seems variable within Japan, a country generally considered to be ethnically and socioeconomically homogeneous. However, 40–80 infants may be congenitally infected and 15–27% (or 6–22) of them may ultimately suffer from certain neurological sequelae annually in Nagasaki Prefecture, so where annual live births are approximately 13,300, congenital CMV infection seems to be a significant public health problem in such an apparently low‐risk region as Nagasaki.     

The colonization incidence of group B streptococcus in pregnant women and their newborns in Istanbul

BACKGROUND: This study was designed to determine the incidence of group B Streptococcus (GBS) colonization in pregnant women and newborns, and to evaluate the antimicrobial resistance during delivery. METHODS: A total of 300 pregnant women and their newborns were enrolled in this prospective study performed in the maternity ward of Cerrahpasa Medical Faculty and Bakirkoy SSK Hospital, Istanbul, Turkey. Samples were collected from pregnant women and their newborns in the delivery room. RESULTS: GBS was isolated from 24 women and the colonization rate was found to be 8%. Two newborns were colonized with GBS. None of the isolates were resistant to penicillin, whereas 20% showed resistance to erythromycin and clindamycin. CONCLUSION: Screening and antimicrobial susceptibility testing of GBS during pregnancy show similar results with other studies performed in different regions of our country.     

Inadequate status of iodine nutrition among pregnant women residing in three districts of Niamey,the Niger Republic's capital

Universal dietary salt iodisation (UDSI) programme was implemented in Niger in 1996. However, since 2000, there has been a slowdown in progress against iodine deficiency. The aim of our study was to assess the iodine status among pregnant women in a context where national controls are not effective at ensuring universal availability of adequately iodised salt. This is mainly to assess the impact of the slowdown in the fight against iodine deficiency in this vulnerable group. The study was centred on 240 healthy pregnant women volunteers recruited in three districts primary health centres. A control group of 60 non‐pregnant, non‐lactating healthy women was also studied and compared. Median urinary iodine concentration (UIC) of all pregnant women was 119 μg L^?1, and 61.67% had UIC below 150 μg L^?1. Median UIC for the first, second and third trimester were 144, 108 and 92 μg L^?1, respectively. The percentage of pregnant women with UIC below 150 μg L^?1 increased from 52% in the first trimester to 66% in the third trimester. The median UIC of the control group was 166 μg L^?1, and 28.33% had UIC below 100 μg L^?1. No significant relationship was found between nutritional iodine status and provenance, age and parity. However, significant relationship was found between iodine status and stage of pregnancy, gestational age and educational level (P < 0.05). Iodine nutrition status thus observed was inadequate in 61.67% of all the pregnant women. It is therefore urgent to revitalise implementation of the UDSI programme, and in the short term to consider iodine supplementation for pregnant women.

Theory‐based nutrition education intervention through male involvement improves the dietary diversity practice and nutritional status of pregnant women in rural Illu Aba Bor Zone,Southwest Ethiopia: A quasi‐experimental study

Maternal undernutrition is a major public health problem that disproportionately affects women in low‐income countries. Despite attempts to address maternal nutritional needs, Ethiopia still has a high rate of undernutrition. Hence, this study aimed to evaluate the effect of theory‐based nutrition education through male engagement on dietary practice and the nutritional status of pregnant women. A pretest−posttest quasi‐experimental study was conducted among 403 pregnant women selected from 22 kebeles of Illu Aba Bor zone, Southwest Ethiopia from July to December 2019. A pre‐tested, structured interviewer‐administered questionnaire was used for data collection. A qualitative 24‐h dietary recall was used to assess dietary diversity, and the Mid‐Upper Arm Circumference was used to assess nutritional status. The intervention effect was evaluated using difference‐in‐difference, generalized estimating equation, and linear mixed‐effects models. The mean dietary diversity score differed significantly between the couple group, women‐alone and the control group (p < 0.001). According to the multivariable generalized estimating equations model, couples were 3.9 times; adjusted odds ratio (AOR) = 3.91, 95% CI: (2.57, 6.88) and women alone were 2.8 times; AOR = 2.86, 95% CI: (2.17, 3.88) more likely to consume a diverse diet than the control group. The nutritional status of the women in the couple group improved significantly by the end of the intervention (p < 0.001). This study showed that involving males in nutrition education intervention was effective in improving the dietary diversity practice and nutritional status of pregnant women. The findings imply the need for targeting couples in designing nutrition education interventions.     

Awareness of and knowledge about mother‐to‐child infections in Japanese pregnant women

To reduce the incidence of infants with congenital infections, women should be aware of and know prevention measures against maternal infection with mother‐to‐child infections during pregnancy. Our objective was to assess the awareness of and knowledge about mother‐to‐child infections in Japanese pregnant women. A survey of 343 Japanese pregnant women was completed. Awareness of 13 pathogens capable of mother‐to‐child transmission was surveyed. Knowledge about the transmission route, the most susceptible time of infection that may cause severe fetal disease during pregnancy, and methods to prevent maternal infection were investigated for four major pathogens (cytomegalovirus, rubella virus, Toxoplasma gondii, and parvovirus B19) and results were compared between these pathogens. The proportion of women aware of pathogens concerning TORCH syndrome was the following: rubella virus 76%, Treponema pallidum 69%, Toxoplasma gondii 58%, parvovirus B19 28%, herpes simplex virus 27%, and cytomegalovirus 18%. Only 8% knew how cytomegalovirus is transmitted, and only 12% knew how parvovirus B19 is transmitted; both were significantly lower than those who knew transmission routes for rubella virus or Toxoplasma gondii. The proportion of women who knew the most susceptible time for severe fetal infection by maternal acquisition of cytomegalovirus, Toxoplasma gondii, or parvovirus B19 was significantly lower than that for rubella virus. The vast majority of surveyed women were not aware of methods to prevent maternal infection with cytomegalovirus or parvovirus B19. In conclusion, current awareness of and knowledge about cytomegalovirus and parvovirus B19 infection are low in Japanese pregnant women.     

Effect of integrated nutrition‐sensitive and nutrition‐specific intervention package on maternal malnutrition among pregnant women in Rwanda

Maternal undernutrition remains a major public health concern in Rwanda despite significant gains and progress. An integration of nutrition‐specific and nutrition‐sensitive interventions was implemented in five districts of Rwanda to improve maternal and child nutrition. The package included nutrition education and counselling, promotion of agricultural productivity, promotion of financial literacy/economic resilience and provision of Water, Hygiene and Sanitation services. However, there is limited evidence about the effect of such interventions in reducing maternal undernutrition. A postintervention quasi‐experimental study was conducted among pregnant women to determine the effect of the integrated intervention on their nutritional status. It was carried out in two intervention districts, namely Kicukiro and Kayonza, and two control districts, namely Gasabo and Gisagara between November 2020 and June 2021. Five hundred and fifty‐two women were recruited for the intervention arm, while 545 were recruited for the control arm. Maternal undernutrition was defined as either having low mid‐upper arm circumference (<23 cm) during delivery or low body mass index (<18.5 kg/m²) in the first trimester or both. A multivariable logistic regression model was used to assess the effect of the integrated interventions. The prevalence of maternal undernutrition was significantly lower in the intervention group compared with the control group (4.7% vs. 18.2%; p < 0.001). After controlling the potential confounders, the risk of maternal undernutrition was 77.0% lower in the intervention group than in the control group [adjusted odds ratio= 0.23; 95% confidence interval = 0.15–0.36; p < 0.001]. Further studies are therefore recommended to establish causation and inform the potential scale‐up of these interventions nationally in Rwanda.     

Validity of a new food frequency questionnaire for pregnant women in the Norwegian Mother and Child Cohort Study (MoBa)

The aim of the present study was to examine the relative validity of foods and nutrients calculated by a new food frequency questionnaire (FFQ) in the Norwegian Mother and Child Cohort Study (MoBa). Reference measures were a 4-day weighed food diary (FD), a motion sensor for measuring total energy expenditure, one 24-h urine collection for analysis of nitrogen and iodine excretion, and a venous blood specimen for analysis of plasma 25-hydroxy-vitamin D and serum folate. A total of 119 women participated in the validation study, and 112 completed the motion sensor registration. Overall, the level of agreement between the FFQ and the FD was satisfactory, and significant correlations were found for all major food groups and for all nutrients except vitamin E. The average correlation coefficient between the FFQ and the FD for daily intake was 0.48 for foods and 0.36 for nutrients, and on average, 68% of the participants were classified into the same or adjacent quintiles by the two methods. Estimated total energy expenditure indicated that under-reporting of energy intake was more extensive with the FD than with the FFQ. The biological markers confirmed that the FFQ was able to distinguish between high and low intakes of nutrients, as measured by vitamin D, folate, protein and iodine. This validation study indicates that the MoBa FFQ produces reasonable valid intake estimates and is a valid tool to rank pregnant women according to low and high intakes of energy, nutrients and foods.     

Prevalence of morbidity symptoms among pregnant and postpartum women receiving different nutrient supplements in Ghana and Malawi: A secondary outcome analysis of two randomised controlled trials

Little is known about the impact of small-quantity lipid-based nutrient supplements (SQ-LNSs) on maternal morbidity. This secondary outcome analysis aimed to compare morbidity symptoms among women in two trials evaluating the efficacy of SQ-LNSs. From enrolment (≤20-week gestation) to 6 months postpartum, Ghanaian (n = 1320) and Malawian (n = 1391) women were assigned to consume daily: 60 mg iron and 400 µg folic acid until childbirth and placebo thereafter (iron and folic acid [IFA] group); or multiple micronutrients (MMN); or 20 g/day SQ-LNSs. Within country, we used repeated measures logistic regression and analysis of variance models to compare group differences in the period prevalence and percentage of days of monitoring when women had fever, gastrointestinal, reproductive, and respiratory symptoms during the second and third trimesters of pregnancy (n ~ 1243 in Ghana, 1200 in Malawi) and 0–3 and 3–6 months postpartum (n ~ 1212 in Ghana, 730 in Malawi). Most outcomes did not differ significantly among groups, with the following exceptions: in Ghana, overall, the prevalence of vomiting was lower in the LNS (21.5%) than MMN (25.6%) group, with the IFA group (23.2%) in-between (p = 0.046); mean ± SD percentage of days with nausea was greater in the LNS (3.5 ± 10.3) and MMN (3.3 ± 10.4) groups than the IFA (2.7 ± 8.3) group (p = 0.002). In Malawi, during 3–6 month postpartum, the prevalence of severe diarrhoea was greater in the LNS (8.1%) than the MMN (2.9%) group, with IFA (4.6%) in-between, p = 0.041). We conclude that the type of nutrient supplement received during pregnancy and lactation generally does not influence morbidity symptoms in these settings. Clinicaltrials.gov identifiers: NCT00970866; NCT01239693.     

Considerations and approaches in determining the protein and energy composition of preterm infant formulas

Optimal early nutritional support is considered a crucial issue in the care of the preterm infant, particularly of those with very low- or extremely low-brithweight. Unfortunately, this goal is seldom satisfactorily attained.
Several conditions such as hypoxia, acidosis, patent ductus arteriosus, drug therapy, reduced intestinal motility may interfere with an adequate nutritional delivery in the early neonatal period. Moreover, there is still concern about metabolic and intestinal tolerance of the currently suggested intakes and a lack of uniformity in the nutritional program among different NICUs. Finally, the vast majority of the available preterm formulas are not fully adequate to the real nutritional needs of these infants. Inadequate protein content and inappropriate protein energy ratio of most preterm formulas represent a matter of major concern, since there is a strict relationship between formula composition and the quantity and quality of weight gain. As a consequence there is a need of at least two milk formulas for different preterm infants: one for LBW and VLBW infants, the other for preterm infants weighing >1500 g.     

Use of micronutrient supplements among pregnant women in Alberta: results from the Alberta Pregnancy Outcomes and Nutrition (APrON) cohort

Maternal nutrient intake in the prenatal period is an important determinant of fetal growth and development and supports maternal health. Many women, however, fail to meet their prenatal nutrient requirements through diet alone and are therefore advised to consume nutrient supplements. The purpose of this study was to describe the use of natural health products (NHP) by pregnant women in each trimester of pregnancy. Women (n = 599) participating in the first cohort of the Alberta Pregnancy Outcomes and Nutrition (APrON) study completed an interviewer‐administered supplement intake questionnaire during each trimester of pregnancy. NHP use was high, with >90% taking multivitamin/mineral supplements, and nearly half taking at least one additional single‐nutrient supplement. Compliance with supplementation guidelines was high for folic acid (>90%), vitamin D (～70%) and calcium (～80%), but low for iron (<30%) and for all four nutrients together (≤11%). On average, women met or exceeded the recommended dietary allowance for folic acid, vitamin D and iron from NHPs alone, with median daily intakes of 1000 μg, 400 IU and 27 mg, respectively. The median calcium intake was 250 mg d^?1. Up to 26% of women exceeded the tolerable upper intake level for folic acid and up to 19% did so for iron at some point of their pregnancy. Findings highlight the need to consider both dietary and supplemental sources of micronutrients when assessing the nutrient intakes of pregnant women.     

Consumption of animal source foods,especially fish,is associated with better nutritional status among women of reproductive age in rural Bangladesh

In rural Bangladesh, intake of nutrient-rich foods, such as animal source foods (ASFs), is generally suboptimal. Diets low in nutrients and lacking in diversity put women of reproductive age (WRA) at risk of malnutrition as well as adverse birth outcomes. The objective of this study was to assess the relationship between maternal dietary diversity, consumption of specific food groups and markers of nutritional status, including underweight [body mass index (BMI) < 18.5 kg/m²], overweight (BMI ≥ 23 kg/m²) and anaemia (haemoglobin < 120 g/dl) among WRA in Bangladesh. This analysis used data from the third round of a longitudinal observational study, collected from February through May of 2017. Dietary data were collected with a questionnaire, and Women's Dietary Diversity Score (WDDS) was calculated. Associations between WDDS, food group consumption and markers of nutritional status were assessed with separate adjusted logistic regression models. Among WRA, the prevalence of underweight, overweight and anaemia was 13.38%, 40.94% and 39.99%, respectively. Women who consumed dark green leafy vegetables (DGLV) or eggs were less likely to be anaemic or underweight, respectively, and women who consumed ASFs, particularly fish, were less likely to be underweight compared with women who did not consume these foods. WDDS did not show any consistent relationship with WRA outcomes. Interventions that focus on promoting optimal nutritional status among WRA in Bangladesh should emphasise increasing consumption of specific nutrient-rich foods, including ASFs, DGLV and eggs, rather than solely focusing on improving diet diversity in general.     

Magnitude and determinants of malnutrition among pregnant women in eastern Ethiopia: evidence from rural,community‐based setting

Maternal malnutrition is a worldwide public health problem affecting a high proportion of pregnant women. This study aimed to determine the magnitude and determinants of malnutrition among pregnant women in eastern Ethiopia. A cross‐sectional study was conducted on 1731 pregnant women selected by a cluster random sampling method. Data on maternal anthropometry and other factors were gathered by trained data collectors. Mid‐upper arm circumference < 22 cm defined malnutrition. Mixed‐effect, multilevel logistic regression was used to control clustering effect. On average, 19.06% of subjects were malnourished, while 23.3% study participants were underweight (body mass index < 19.8 kg m^?2). In the final adjusted analysis, the risk of malnutrition was more than twofold higher in pregnant women with low (adjusted odds ratio = 2.47, 95% confidence interval = 1.41–4.34) and medium (adjusted odds ratio = 2.74, 95% confidence interval = 1.40–5.35) autonomy of household decision‐making than those who had high level of autonomy in household decision‐making. Husband illiteracy and not owning livestock were associated with increased risk of malnutrition. Women in the second and third trimester had a 66% and nearly twofold increased risk of malnutrition compared with their counterparts in the first trimester, respectively. Women who improved their eating habits had a 53% lower risk of malnutrition than those who did not. The risk of malnutrition was 39% lower in respondents who received prenatal dietary advice than in those who did not. Malnutrition affects at least one of every five pregnant women studied, calling for priority attention. Interventions that improve maternal involvement in household decision‐making autonomy and provision of prenatal dietary advice are recommended.
