Understanding Maternal Nutrition Insights from Pregnant Women in Bamenda, Cameroon

The foundation for good physical health is good nutritional status. Nutritional status of pregnant women is directly affected by the foods they eat and their nutrient content. Nutritional knowledge is positively associated with diet quality. The aim of this study was to assess nutritional status and nutrition education knowledge of pregnant women attending antenatal clinics in Bamenda Health District (BHD). 
 Study Design: This study was carried conducted in BHD in the North West Region of Cameroon, with pregnant women aged 13 to 49 years recruited from public hospitals.
 Place and Duration of Study: BHD including (Bamenda Regional Hospital, Azire Integrated Health centre, Atuakom Integrated Health Centre, Ntambag Integrated Health Centre) between April 2022 to September 2022.
 Methodology: This was a cross sectional study carried out in four health facilities BHD. Random sampling technique was done to target the sample size of 354 pregnant women. A questionnaire was developed to collect socio-demographic information and clinical records of the pregnant women. Anthropometric parameters, biochemical and dietary assessments of the women were determined using standard techniques. Data collected was analysed by MS excel and SPSS Statistics version 20.0. Results were considered at significance level P ≤ 0.05. 
 Results: The mean age of the study population was 26.4±5.5years and the average intake of servings of meals per day was suboptimal in the consumption of vegetables (2±1.9), fruits (0.6± 1.3) and milk (0.4 ±0.6) food groups. Women consumed diets that met less than 50% of energy needs. There exists a significant difference in mean energy requirements 1828.8 ± 152.9 Kcal compared to mean energy intake 1192.0 ± 344.6 Kcal which is below the Recommended Daily Allowances (RDA) of 2400 kcal for pregnant women. Ignorance still existed in dietary knowledge and 18.1% of the women were anaemic. 
 Conclusion: There was an overall suboptimal approach to dietary intake among the pregnant women, inadequate food intake, poor food choices and limited healthy dietary knowledge. Thus pregnant women in BHD still need more access to information on dietary information.

Faktor- Faktor Yang Mempengaruhi Kejadian Stunting Pada Balita Di Indonesia Tahun 2024

Stunting caused by malnutrition during the growth and development process has a higher risk of illness and death in adulthood, so it can hamper motor skills and reduce the level of productivity and competitiveness of a nation (Rahmadhita, 2020). National nutritional status survey data (SSGI) in 2022, the prevalence of stunting was 21.6%. The target stunting rate in Indonesia is 14% in 2024 and the WHO standard target is below 20%, therefore how important it is to handle stunting in Indonesia. The aim of this research is to determine the factors that influence the incidence of stunting in toddlers. The method in this research is a full text critical review in Indonesian. Articles were selected in stages using the appraisal tool preferred reporting items for systematic reviews and meta analyzes (PRISMA), then duplicate filtering was carried out, screening was carried out based on title and abstract, full text, feasibility studies and until the final stage 11 articles were found that met the inclusion and study criteria. appropriateness. The results of this research show that the factors that influence the incidence of stunting in toddlers are exclusive breastfeeding, low birth weight, infectious diseases, mother's height, mother's education, family income, and nutritional status of pregnant women.

Correlation between Body Mass Index with Anaemia Status of Pregnant women after Intervention Infused Okra Water and Ferrous Sulfate

Background: Lack of intake of macronutrients such as energy, protein and micronutrients such as iron, vitamins in the daily diet of pregnant women is a problem that has an impact on iron deficiency and chronic energy deficiency. To increase the bioavailability and absorption of iron sulfate supplements and improve the nutritional status of pregnant women, researchers provide interventions by consuming infused okra water. Okra contains macronutrients and micronutrients that can provide nutrition during pregnancy and increase iron absorption. This study aims to analyse the nutritional status of pregnant women by measuring BMI and its relation to their anaemia status. Methods: This research is a experimental study with a one group pretest-posttest design. The population in this study was all pregnant women with gestational ages of 16–32 weeks and Hb levels less than 11 gr/dl. Purposive sampling was used to collect 50 samples from 50 people. The intervention provided was 100 grams of fresh okra fruit, which had been made into infused okra water, which was then drunk by the respondents after consuming ferrous sulphate tablets 60 mg per day. To analyse the relationship between BMI and anaemia status, the researchers used the chi-square test. Results: There was no relationship between increases in BMI and Hb levels in pregnant women in this study. Conclusions: An increase in body mass index (BMI) in pregnant women who were given infused okra water and ferrous sulphate tablets did not have a positive effect on haemoglobin levels. Based on BMI, it appears that pregnant women are not malnourished.

Anemia profiling in antenatal women at a tertiary care center in northern India: An observational study

: Anemia is a common health issue during pregnancy, with various factors influencing its occurrence. Iron deficiency often leads to iron deficiency anemia (IDA), significantly impacting maternal and fetal health.: This study aims to investigate the complete blood count and nutritional status, including serum iron profile, vitamin B12, and folate levels in antenatal patients. : The study involved 160 participants, predominantly from rural areas. The severity of anemia among the participants was classified according to WHO guidelines.: Iron deficiency was observed in 33.75% of women, folate deficiency in 20%, and vitamin B12 deficiency in 11.25%. Some women exhibited a combination of deficiencies. The average hemoglobin level was found to be 8.69 g/dL, and the mean iron level was 35.95 µg/dL. The average ferritin levels were observed to be 49.65 ng/mL. Lastly, the Vitamin B12 and folate levels averaged at 130.21 pg/mL and 14.76 ng/mL respectively.: These findings provide valuable insights into the nutritional status of pregnant women and highlight the need for targeted interventions to address micronutrient deficiencies during pregnancy.

Salivary iodine concentration in pregnant women and its association with iodine status and thyroid function.

There have been no reports on the application of salivary iodine concentration (SIC) in evaluating iodine nutrition in pregnant women. This study aimed to clarify the relationship between SIC and indicators of iodine nutritional status and thyroid function during pregnancy, to investigate whether salivary iodine can be applied to the evaluation of iodine nutritional status in pregnant women, and to provide a reference basis for establishing a normal range of salivary iodine values during pregnancy. Pregnant women were enrolled in the Department of Obstetrics, the people's hospital of Yuncheng Country, Shandong Province, from July 2021 to December 2022, using random cluster sampling. Saliva, urine, and blood samples were collected from pregnant women to assess iodine nutritional status, and venous blood was collected to determine thyroid function. A total of 609 pregnant women were included in this study. The median spot urinary iodine concentration (SUIC) was 261μg/L. The median SIC was 297μg/L. SIC was positively correlated with SUIC (r = 0.46, P < 0.0001), 24-h UIC (r = 0.30, P < 0.0001), 24-h urinary iodine excretion (24-h UIE) (r = 0.41, P < 0.0001), and estimated iodine intake (EII) (r = 0.52, P < 0.0001). After adjusting for confounders, there was a weak correlation between SIC and serum total iodine and serum non-protein-bound iodine (P = 0.02, P = 0.04, respectively). Pregnant women with a SIC < 176μg/L had a higher risk of insufficient iodine status (OR = 2.07, 95% CI 1.35-3.19) and thyroid dysfunction (OR = 2.71, 95% CI 1.18-6.21) compared to those with higher SIC. Those having SIC > 529μg/L were more likely to have excessive iodine status (OR = 2.82, 95% CI 1.81-4.38) and thyroid dysfunction (OR = 3.04, 95% CI 1.36-6.78) than those with lower SIC values. SIC is associated with urinary iodine concentration and thyroid function in pregnant women. SIC < 176μg/L was associated with an increased risk for iodine deficiency and hypothyroxinemia, while SIC > 529μg/L was related to excess and thyrotoxicosis. SIC can be used as a reference indicator for evaluating the iodine nutrition status of pregnant women, but it needs further investigation and verification. NCT04492657(Aug 9, 2022).

Nutritional status of pregnant women and its impact on child stunting incidence in Indonesia: Literature review

The aim of this research is to determine the relationship between the nutritional status of pregnant women and the incidence of stunting in children in Indonesia based on a review of several related studies. The research method used is a literature review by searching for research articles related to the topic of stunting and nutrition of pregnant women in Indonesia in the last 10 years from online databases. Relevant articles were collected and analyzed systematically. Several studies show that pregnant women with poor nutritional intake and status are at risk of giving birth to babies with stunting and low birth weight. Other factors such as diet, personal hygiene and infections also influence the nutritional status of pregnant women. Poor nutritional status of pregnant women contributes significantly to the risk of stunting in children. Optimizing the nutrition of pregnant women through supplementation, education and increasing access to nutritious food is important as an effort to prevent stunting from an early age.

DIETARY HABITS AND ASSOCIATED FACTORS OF PREGNANT WOMEN ATTENDING ANTENATAL CLINICS AT TOWNSHIP HOSPITALS IN NAYPYIDAW TERRITORY, MYANMAR

Pregnancy is a critical period during which good maternal nutrition is an important factor that affects the health of both the mother and the child. The study aims to assess the knowledge, attitudes, dietary habits and nutritional status of pregnant women. A cross-sectional descriptive study was conducted from October 2022 to February 2023 among 400 pregnant women attending antenatal clinics of four selected township hospitals at Naypyidaw Territory. Of 400 pregnant women, only 18% of the pregnant women were undernourished in this study. Few (6%) of the pregnant women had high nutritional knowledge, yet most of the pregnant women (78.5%) had favorable attitudes towards nutrition. More than half (64.8%) had good dietary habits in this study. Educational level, estimated average family income, number of antenatal visits, and nutritional knowledge of the pregnant women were significantly associated with the dietary habits of the respondents according to bivariate analysis. Multivariable logistic regression analysis revealed that the number of antenatal visits and nutritional knowledge of pregnant women were significantly influenced by their dietary habits. The pregnant women who attended more frequent antenatal visits had better dietary habits than those with less frequent antenatal visits [AOR =2.00; 95% CI (1.14,3.5), p-value=0.016)]. Additionally, pregnant women with a high nutritional knowledge level were more likely to have better dietary habits [(AOR=6.96; 95% CI (1.57, 30.98), p-value = 0.011]. Nutrition education programs should be emphasized on frequent antenatal visits to improve the nutritional knowledge and dietary habits of pregnant women.&#x0D;

The Influence of Hemoglobin Levels and Nutritional Status of First-Trimester Pregnant Woman with Low Birth Weight

Premature birth is identified as the most significant contributor to infant mortality. The weight of a newborn baby is determined by nutritional status at the time of conception. Pregnant women who are malnourished and experience physical weakness will endanger the mother's life and threaten the safety of the fetuce. LBW can be caused by anemia, inadherence to antenatal care, mothers with chronic diseases and smoking. This study aimed to determine the influence of hemoglobin levels and nutritional status of first-trimester pregnant women with low birth weight events. This type of quantitative research is a retrospective design. The population are mothers who gave birth at the Kabuh Community Health Center, Jombang Regency, in April 2019 obtained a sample of 39 respondents using a purposive sampling, with inclusion criteria birthing mothers have a KIA book. The data were analyzed using logistic regression. The results showed that almost all (79.5%) 31 pregnant women were not anaemic, almost all (84.6%) 33 pregnant women had normal nutritional status and almost all (76.9) babies were born with average weight, namely 30 respondents. There is a relationship between Hemoglobin levels in pregnant women and the incidence of LBW with a value of p = 0.000. There is a relationship between the nutritional status of pregnant women and the incidence of LBW with a value of p = 0.000. The most dominant factor is Hb levels (p=0.001 exp B:30) Pregnant women are anaemic, one of the factors causing poor nutritional status. Nutritional status lacks calorie energy, inhibiting the fetus's nutritional intake, resulting in premature labour or disruption of fetal growth.

Development and validation of a novel food exchange system for Chinese pregnant women

BackgroundThe dietary nutritional status of pregnant women is critical for maintaining the health of both mothers and infants. Food exchange systems have been employed in the nutritional guidance of patients in China, although their application in the dietary guidance of healthy pregnant women is quite limited. This study aimed to develop a novel food exchange system for Chinese pregnant women (NFES-CPW) and evaluate the relative validation of its application.MethodsNFES-CPW covers approximately 500 types of food from ten categories and has more elaborate food portion sizes. It established a recommendation index for guiding food selection and used energy, water content, and protein as the exchange basis to balance the supply of energy and important nutrients throughout pregnancy. Furthermore, dietitians used the NFES-CPW and traditional food exchange system to generate new recipes based on the sample recipe. There were 40 derived recipes for each of the two food exchange methods. The food consumption, energy, and key nutrients of each recipe were calculated, and the differences between the two food exchange systems were compared using the Wilcoxon rank sum test or the Chi-square test.ResultsThe results revealed that compared to those derived from traditional food exchange system, the NFES-CPW derived recipes had a better dietary structure, as evidenced by the intakes of whole-grain cereals, beans excluding soybeans, potatoes, fruits, fish, shrimp and shellfish, as well as eggs (P < 0.05), which were more conducive to reaching the recommended range of balanced dietary pagoda. After calculating energy and nutrients, although these two food exchange systems have similar effects on the dietary energy and macronutrient intake of pregnant women, the intake of micronutrients in NFES-CPW derived recipes was significantly higher than that from the traditional food exchange system, which was more conducive to meeting the dietary requirements of pregnant women. The outstanding improvement are primarily vitamin A, vitamin B2, folic acid, vitamin B12, vitamin C, calcium, iron, and iodine (P < 0.05). Moreover, when compared to recipes obtained from the traditional food exchange system, the error ranges of energy and most nutrients were significantly reduced after employing the NFES-CPW.ConclusionsTherefore, NFES-CPW is an appropriate tool that adheres to Chinese dietary characteristics and can provide suitable dietary guidance to pregnant women.

Factors related to HbA1c in the first trimester of pregnancy

The prevalence of gestational diabetes mellitus (GDM) in the world is 16.2% of live births associated with hyperglycemia in pregnancy, and 7.4% are caused by type 1 or 2 diabetes which is detected for the first-time during pregnancy. The prevalence of GDM in Indonesia reaches 3.6% and the highest rate is found in the Special Province of Yogyakarta (2.6%). One of the risk factors for GDM is excess nutrition which is influenced by daily intake. This study aims to determine the relationship between nutritional intake and body mass index (BMI) with HbA1c levels in first-trimester pregnant women. This study used a cross-sectional design. A simple random sampling with inclusion and exclusion criteria was employed, involving 47 pregnant women as subjects. Nutritional intake was measured with the semi-quantitative food frequency questionnaire (SQ-FFQ). The nutritional status of pregnant women is measured by BMI. HbA1c was measured by the turbidimetric inhibition immunoassay (TINIA) method. Analysis of research data using the Pearson product-moment correlation test and rank Spearman. The results of this study stated that there was a relationship between nutritional intake and BMI with HbA1c levels. Diagnosis of GDM and appropriate intervention can reduce the risk of complications of diabetes mellitus (DM).

Evaluation of the nutritional status and care of pregnant women in the Allada-Toffo-Zè health zone (Benin)

This work aims to assess the nutritional status of pregnant women in the health zone of Allada-Toffo-Zè. It consisted of conducting an interview with pregnant women meeting the criteria of pregnant women and coming for prenatal consultation. During this study, 200 pregnant women were surveyed in health facilities in the health zone. The results showed that 80% of pregnant women have never received nutritional advice, which leads them to not control their diet. In addition, there is a relationship between the malnutrition of pregnant women and the age of pregnant women, and their profession. Indeed, pregnant women aged over 30 years are 1.85 times more malnourished than pregnant women under 20 years of age (p=0.007). Also, resellers or shopkeepers are 1.49 times more malnourished than housewives (p=0.001). Finally, weight and MUAC were associated with malnutrition in pregnant women. Therefore, pregnant women weighing more than 55 kg were malnourished than pregnant women weighing less than 55 kg (p=0.01). Those whose MUAC greater than 24 cm were malnourished (p=0.003).

Traditional Knowledge Systems: Cross-Culturally Exploring The Medical Anthropology of Diet Wellness

Traditional Knowledge Systems (TKS) in Indigenous communities worldwide shape lifestyle and eating habits, with a focus on the thermostatic properties of food and balance in the body. Traditional Chinese Medicine (TCM) and Ayurveda are examples of TKS that emphasize individualized diets based on factors such as age, season, and constitution. In Indigenous communities, cultural beliefs about food during pregnancy influence dietary choices. Villagers in South India consider pregnancy a "hot" condition and restrict the consumption of "hot" foods to prevent excessive heat in the body. Additionally, climate change impacts food security in Indigenous communities, affecting the nutritional status of pregnant women. In Uganda, the Batwa community experienced a loss of traditional food sources due to eviction from their lands, exacerbating food insecurity during pregnancy. Climate change also affects food accessibility and the gender disparities in agriculture contribute to food insecurity. Furthermore, gender differences play a role in the relationship between interpersonal stress and shape and weight concerns, with girls showing stronger correlations in these areas. In this review, we uncover the intricacies associated with creating a diet and emphasize the wide range of cultural influences that shape these choices on an individual and communal scale.

Effectiveness of nutrition counseling for pregnant women in low- and middle-income countries to improve maternal and infant behavioral, nutritional, and health outcomes: A systematic review.

Nutritional counseling, which includes two-way interactive education, has been hypothesized to improve the health and nutritional status of pregnant women, but little is known about the impact such practice of care might have on maternal and infant health and behavioral outcomes of pregnant women living in low income, low-middle income, and upper-middle-income countries (LMIC)s. We conducted a systematic review to appraise the effectiveness and impact on health equity of two-way nutritional counseling practices in LMICs on maternal and infant behavioral, nutritional, and health outcomes. We conducted electronic searches for relevant studies on Medline, Embase, CINAHL, PsychInfo, and the Cochrane CENTRAL for randomized and non-randomized trials on the effectiveness of two-way interactive nutritional counseling among pregnant women from the date of database inception up to June 22, 2021. In addition, we searched references of included studies in systematic reviews, gray literature resources, and unpublished studies or reports that satisfied our eligibility criteria using a focused Google search. We included randomized and non-randomized controlled studies (NRS), controlled before and after, and interrupted time series that assessed the effectiveness of two-way interactive nutrition counseling targeting pregnant women in LMICs. Data extraction and risk of bias were conducted in duplicate. The risk of bias (ROB) for randomized trials (RCT) was assessed according to the Cochrane Handbook of Systematic Reviews, and ROB for NRS was assessed using the Newcastle-Ottawa scale (NOS). RCT and NRS were meta-analyzed separately. Our search identified 6418 records and 52 studies met our inclusion criteria, but only 28 were used in the quantitative analysis. Twenty-eight studies were conducted in Asia, the most in Iran. Eight studies were conducted in Africa. Two-way interactive nutritional counseling during pregnancy may improve dietary caloric intake (mean difference [MD]: 81.65 calories, 95% confidence interval [CI], 15.37-147.93, three RCTs; I 2 = 42%; moderate certainty of evidence using GRADE assessment), may reduce hemorrhage (relative risk [RR]: 0.63; 95% CI, 0.25-1.54, two RCTs; I 2 = 40%; very low certainty of evidence using GRADE assessment), may improve protein (MD: 10.44 g, 95% CI, 1.83-19.05, two RCTs; I 2 = 95%; high certainty of evidence using GRADE assessment), fat intake (MD: 3.42 g, 95% CI, -0.20 to 7.04, two RCTs; I 2 = 0%; high certainty of evidence using GRADE assessment), and may improve gestational weight gain within recommendations (RR: 1.84; 95% CI, 1.10-3.09, three RCTs; I 2 = 69%). Nutrition counseling probably leads to the initiation of breastfeeding immediately after birth (RR: 1.72; 95% CI, 1.42-2.09, one RCT). There was little to no effect on reducing anemia (RR: 0.77; 95% CI, 0.50-1.20, three RCTs; I 2 = 67%; very low certainty of evidence using GRADE assessment) risk of stillbirths (RR: 0.81; 95% CI, 0.52-1.27, three RCTs; I 2 = 0%; moderate certainty of evidence using GRADE assessment) and risk of cesarean section delivery (RR: 0.96; 95% CI, 0.76-1.20, four RCTs; I 2 = 36%; moderate certainty of evidence using GRADE assessment). Our review highlights improvements in maternal behavioral and health outcomes through interactive nutrition counseling during pregnancy. However, we are uncertain about the effects of nutrition counseling due to the low certainty of evidence and a low number of studies for some key outcomes. Moreover, the effects on health equity remain unknown. More methodologically rigorous trials that focus on a precise selection of outcomes driven by the theory of change of nutrition counseling to improve maternal and infant behavioral and health outcomes and consider equity are required.

FRI484 Assessment Of Early-trimester Maternal Thyroid Function And Iodine Nutritional Status Of Pregnant Women In Northern Taiwan

Abstract Disclosure: G. Su: None. C. Yeh: None. C. Yang: None. C. Hwu: None. H. Chen: None. F. Wang: None. C. Huang: None. Background: The American Thyroid Association (ATA) has proposed to lower the early-trimester upper limit of the TSH reference interval to become 0.5 mIU/L less than the non-pregnant value. The local-regional reference intervals in Taiwan is unknown. The aim of the study is to evaluate the early-trimester thyroid function and iodine nutritional status of pregnant women in Taiwan. Methods: Women aged ≥20 years-old and in gestation 8 to 15 weeks were recruited in Taipei Veterans General Hospital from March 2019 to July 2022. Thyroid function and antibodies, including TSH, free T4, free T3, total T4, total T3, anti-thyroglobulin antibody (aTG) and anti-thyroidperoxidase antibody (aTPO), TSH receptor antibody, were measured. The gestation-specific thyroid function reference range was derived from the 2.5th and 97.5th percentiles of the studied women. Random spot urine sample was collected and urinary iodine concentration was checked by inductively coupled plasma mass spectrometry. A simple food frequency questionnaire was also completed. Results: A total of 211 women were enrolled and the derived early-trimester upper limit of serum TSH (median: 0.92 [0.007-3.08] uIU/mL) was lower than the value provided by the manufacturer (0.27-4.2 uIU/mL), while the upper limit of free T4 (median: 1.28 [0.93-2.15] ng/dL) and free T3 (3.00 [2.30-5.10]ng/dL) were both higher than the non-pregnant value (0.93-1.7 ng/dL and 2.0-4.4 ng/dL, respectively). The range of total T4 (median: 9.90 [6.39-15.36] ng/dL) and total T3 (median: 136 [89.50-223.20] ng/dL) in the studied women were similar to the non-pregnant range (5.1-14.1 ng/dL and 80-200 ng/dL, respectively). The positivity rate of aTG &amp; aTPO were 8.6%. Two patients with mild Graves’ disease and three patients with subclinical hypothyroidism were incidentally detected and treated. The positive predictive value for detecting thyroid dysfunction using the non-pregnant reference interval was only 15.9% because subclinical hyperthyroidism (18.2%, n=37) would be over-diagnosed and subclinical hypothyroidism (1.0%, n=2) would be under-diagnosed. The overall median UIC was 160.9 μg/L, indicating a sufficient iodine status. Dairy products were the most commonly consumed iodine-containing food type with 71.8% of the pregnant women ingesting dairy products ≥3 days/week. The median intake frequency for seaweed, fish, and seafood were one day per week. Approximately 34.0% of the women took multivitamin every day, but 58.4% of the women never took multivitamin. Conclusion: Our results indicate that the iodine nutritional status in the early trimester of pregnancy is adequate and that the upper limit of serum TSH was approximately 1.12 uIU/mL lower than the upper limit provided by the manufacturer. Gestation-specific thyroid function reference intervals are needed for correct diagnosis of thyroid dysfunction in pregnancy. Presentation: Friday, June 16, 2023
