The Impact of Docosahexaenoic Acid (DHA) Supplementation on Calcium Levels in Third Trimester Pregnant Women with Chronic Energy Deficiency (CED): A Correlational Study

Background: Chronic Energy Deficiency (CED) during pregnancy represents a critical health challenge, especially in developing regions, where it significantly threatens maternal and fetal well-being. Docosahexaenoic Acid (DHA), an essential omega-3 fatty acid, plays a pivotal role in fetal neurodevelopment and maternal health. However, the impact of DHA supplementation on maternal calcium levels, particularly among pregnant women affected by CED, has not been extensively studied. This study evaluate the correlation between DHA supplementation and calcium levels in third-trimester pregnant women with CED, with the goal of improving outcomes for this vulnerable population. Method and Results: This research uses experimental cohort study design with a quantitative approach, using non-probability sampling techniques such as quota and purposive sampling, and involving a total of 24 participants. Statistical analysis revealed a significant increase in calcium levels following DHA supplementation, with a p-value of 0.007 (<0.05), indicating a notable impact of the intervention. The mean calcium levels post-treatment were higher than pre-treatment, demonstrating the efficacy of DHA supplementation in improving calcium levels. Further analysis showed no significant correlation between pre-supplementation calcium levels and Body Mass Index (BMI) (p = 0.622, > 0.05). However, a significant correlation was found between post-supplementation calcium levels and BMI (p = 0.002, < 0.05). These findings indicate a positive correlation between DHA supplementation and calcium levels in pregnant women with CED during the third trimester. However, further investigation is needed to fully understand the relationship between calcium levels and BMI. Conclusion: This study lays the groundwork for future research aimed at optimizing therapeutic interventions or supplementation strategies to improve the nutritional status of underweight pregnant women.

Comparison of Obstetric Outcomes Among Various Weight Strata in a Teaching Hospital in Southwest, Nigeria

AIM:The aim of the study is to evaluate the trend in adverse obstetric outcomes of parturients across the spectrum of body mass index.METHODS:This is a cohort study of pregnant women who received obstetric care at the Obstetrics and Gynecology Department of the Ekiti State University Teaching Hospital, Ado-Ekiti, between January 2015 and December 2015. The data were prospectively collected into the Obstetric Data Registry of the department. Composite adverse maternal outcomes and composite adverse fetal outcomes were obtained for each group. Data were analyzed with SPSS version 24, and ap-value of less than .05 was considered statistically significant.RESULTS:Out of the 1,006 parturients, 334 (33.2%) were obese. Composite adverse maternal outcome increased from 35.1% for women with normal weight to 62.3% for obese women (p< .001). Composite adverse fetal outcome also increased from 25.9% for women with normal weight to 30% for obese women (p< .001). The odds of composite adverse maternal outcome were increased in overweight women (adjusted odds ratio [aOR] 1.52, 95% confidence interval [CI] [1.12, 3.49]) and obese women (aOR 1.65, 95% CI [1.21, 2.24]) compared with women with normal weight. Also, the odds of composite adverse fetal outcome were reduced in overweight (aOR 0.64, 95% CI [0.44, 0.93]) but increased in underweight (aOR 4.78, 95% CI [2.00, 11.44]) and obese (aOR 1.16, 95% CI [1.03, 12.39]) women.CONCLUSION:Composite adverse obstetric outcomes were increased in underweight, overweight, and obese women when compared with women with normal weight.

Adipose tissue insulin resistance in young Japanese women is associated with metabolic abnormalities and dehydroepiandrosterone-sulfate.

The proportion of young Japanese women who are underweight is exceptionally high. We previously showed that the prevalence of impaired glucose tolerance (IGT) was high in underweight young Japanese women, and that IGT was characterized by high free fatty acid levels and adipose tissue insulin resistance (ATIR). As the next step, this study aimed to explore factors associated with elevated ATIR in this population. Ninety-eight young, healthy, underweight women participated in this study. To investigate the relationship between ATIR and metabolic parameters, participants were divided into three groups (Low, Medium, and High) according to ATIR level. Body composition examination, oral glucose tolerance testing, and blood biochemical analysis were performed; Adipo-IR and the Matsuda index were used as indices of ATIR and systemic insulin sensitivity, respectively. Participants in the High ATIR group had the highest prevalence of IGT (25%), and significantly higher body fat percentage, whole-body insulin resistance, and levels of insulin-like growth factor-1 and dehydroepiandrosterone sulfate (DHEA-S) than the other two groups. They were also significantly younger and had higher systolic blood pressure than the Low ATIR group. Multiple regression analysis showed that DHEA-S, which is known to enhance lipolysis in adipose tissue, was an independent correlate of ATIR. Underweight Japanese women with high ATIR had impaired metabolism, a higher prevalence of IGT, higher systemic insulin resistance, and higher systolic blood pressure. DHEA-S was a determinant of high ATIR levels.

Dietary patterns of Polish pregnant women in reference to prepregnancy BMI and gestational weight gain.

During the life cycle of a woman, pregnancy is the period when she is most open to changing her behaviour and lifestyle for the benefit of the child's development. Lifestyle changes include also the diet correction. The objective of the study was to assess, through identified dietary patterns, the diets of women in the second and third trimester of pregnancy in relation to their nutritional status before and during pregnancy. The study was conducted among pregnant women, participants of childbirth education classes at the Institute of Mother and Child, based on food frequency questionnaire. The study involved 392 women in the age 19-40 years (first single pregnancy without complications). Dietary patterns were identified using the k-means method, based on groups of products. Three dietary patters were identified in the study group of women: dietary pattern 1 - cereal-milk diet, dietary pattern 2 - vegetable-fruit diet and dietary pattern 3 - cottage cheese-vegetable diet. Dietary pattern 3 occurred in 43.9% of underweight women, in 45.5% of women with normal weight and in 43.1% of women with excess body weight. Dietary pattern 1 occurred in about one third of women and dietary pattern 2 in about 20% in each group. A greater diversity in the frequency of identified dietary patterns was observed in relation to weight gain during pregnancy. The identified dietary patterns differed significantly in terms of the profile of macronutrients, most minerals and vitamins - E, C and B group vitamins. The identified dietary patterns and their energy and nutritional profile indicate the need for monitoring the diets and nutritional education of pregnant women.

Association between Gestational Weight Gain and Pregnancy Outcomes in Various Body Mass Index Groups: A Retrospective Observational Study

Abstract Introduction: Body mass index (BMI) has been known to be an important determinant of pregnancy morbidities. However, multiple studies show that the effects are equally dependent on the gestational weight gain (GWG). There is a lack of data in the Indian population, especially using the Asia–Pacific guidelines of BMI. This study is meant to identify the degree of association between the GWG in different BMIs and the development of pregnancy morbidities. Materials and Methods: This was a retrospective study, in which case records of women who delivered in our hospitals during 1 year were analyzed. Pregnancy outcomes, such as growth restriction, preterm deliveries, development of hypertensive disorders, gestational diabetes, inductions, and cesareans, were analyzed in three classes of GWG inadequate, adequate, and excess GWG (as per institue of medicine guidelines). The Chi-square test was done to see the difference in the pregnancy outcomes. Results: Of the 1396 women enrolled, women with inadequate GWG had higher preterm deliveries (13.8% vs. 4.4%, P < 0.001) and fetal growth restriction (8.8% vs. 3.9%, P = 0.003) with higher odds in underweight women with inadequate GWG (odds ratio [OR] of 2.6 and 1.75, respectively). Excess GWG had a significantly higher induction (34.9% vs. 29%, P > 0.05) and cesarean delivery rate (34.3% vs. 21.6%, P = 0.003) with higher odds seen in obese women with excess GWG (OR of 2.6 and 1.75, respectively). Conclusion: All women having out-of-range BMI should be identified during the first antenatal contact. Inadequate GWG in underweight women and excess GWG in obese women should be strictly monitored and targeted to prevent a wide spectrum of maternal morbidities.

The relationship between brain structure volumes, depressive symptoms and body composition in obese/overweight and normal-/underweight women

Depressive symptoms are highly prevalent and heterogeneous in women. Different brain structures might be associated with depressive symptoms and body composition in women with obesity/overweight and normal-/underweight, although the data is limited. The analysis included 265 women from Bialystok PLUS population study, untreated with antidepressive or antipsychotic medications. The subjects underwent brain magnetic resonance imaging and body composition analysis. Beck Depression Inventory (BDI) score was inversely associated with nucleus accumbens volume (β = −0.217, p = 0.008) in women with BMI ≥ 25 kg/m2, but with insula volume (β = −0.147, p = 0.027) in women with BMI < 25 kg/m2 after adjustment for age and estimated intracranial volume (eTIV). In women with BMI ≥ 25 kg/m2, nucleus accumbens volume was inversely associated with the percentage of visceral fat and BDI score (β = −0.236, p = 0.012, β = −0.192, p = 0.017) after adjustment for age and eTIV. In women with BMI < 25 kg/m2, insula volume was positively associated with total fat-free mass and negatively with the BDI score (β = 0.142, p = 0.030, β = −0.137, p = 0.037) after adjustment for age and eTIV. Depressive symptoms might be associated with nucleus accumbens volume in overweight/obese women, while in normal-/ underweight women—with alterations in insula volume.

Association of pre-pregnancy body mass index and gestational weight gain on postpartum pelvic floor muscle morphology and function in Chinese primiparous women: A retrospective cohort study.

Our study aimed to investigate the association between maternal pre-pregnancy body mass index (BMI), gestational weight gain (GWG), and impaired pelvic floor muscle (PFM) morphology and function during the early postpartum period. This retrospective cohort study was conducted at Shanghai First Maternity and Infant Hospital from December 2020 to December 2022. A total of 1118 primiparous women with singleton pregnancies who underwent vaginal deliveries and participated in postpartum PFM assessments were included. Maternal pre-pregnancy BMI and GWG were considered as exposures. PFM morphology and function impairment were the primary outcomes. PFM morphology impairment, defined as levator ani muscle avulsion, was assessed using transperineal ultrasound. PFM function impairment, manifested as diminished PFM fiber strength, was assessed through vaginal manometry. Multivariable logistic regression analysis was employed to calculate adjusted odds ratios (aOR) with 95% confidence intervals (CI). Restricted cubic spline models were used to validate and visualize the relationship. Women with lower pre-pregnancy BMI were at an increased risk of levator ani muscle avulsion (aOR = 1.73, 95% CI: 1.10-2.70, P = 0.017), particularly when combined with excessive GWG during pregnancy (aOR = 3.20, 95% CI: 1.15-8.97, P = 0.027). Lower pre-pregnancy BMI was also identified as an independent predictor of PFM weakness (aOR = 1.53, 95% CI: 1.08-2.16, P = 0.017 for type I fiber injuries). Notably, regardless of the avulsion status, both underweight and overweight/obese women faced an elevated risk of reduced PFM strength (aOR = 1.74, 95% CI: 1.17-2.59, P = 0.006 for underweight women with type I fiber injuries; aOR = 1.67, 95% CI: 1.06-2.64, P = 0.027; and aOR = 1.73, 95% CI: 1.09-2.76, P = 0.021 for overweight/obese women with type I and type II fibers injuries, respectively). Both lower and higher pre-pregnancy BMI, as well as excessive GWG, were strongly associated with PFM impairments. These findings highlighted the critical importance of comprehensive weight management throughout pregnancy to effectively promote women's pelvic health.

Concordance of weight status between mothers and children: a secondary analysis of the Pakistan Demographic and health survey VII

BackgroundFamilial concordance of weight status is an emerging field of study that may guide the development of interventions that operate beyond the individual and within the family context. There is a dearth of published data for concordance of weight status within Pakistani households.MethodsWe assessed the associations between weight status of mothers and their children in a nationally representative sample of households in Pakistan using Demographic and Health Survey data from 2017–18. Our analysis included 3465 mother–child dyads, restricting to children under-five years of age with body mass index (BMI) information on their mothers. We used linear regression models to assess the associations between maternal BMI category (underweight, normal weight, overweight, obese) and child’s weight-for-height z-score (WHZ), accounting for socio-demographic characteristics of mothers and children. We assessed these relationships in all children under-five and also stratified by age of children (younger than 2 years and 2 to 5 years).ResultsIn all children under-five and in children 2 to 5 years, maternal BMI was positively associated with child’s WHZ. For all children under-five, children of normal weight, overweight, and obese women had WHZ scores that were 0.21 [95% CI (confidence interval): 0.04, 0.37], 0.43 [95% CI: 0.25, 0.62], and 0.51 [95% CI: 0.30, 0.71] units higher than children of underweight women, respectively. For children ages 2 to 5, children of normal weight, overweight, and obese women had WHZ scores that were 0.26 [95% CI: 0.08, 0.44), 0.50 [95% CI: 0.30, 0.71), and 0.61 [95% CI: 0.37, 0.84] units higher than children of underweight women, respectively. There was no association between maternal BMI and child WHZ for children under-two.ConclusionsThe findings indicate that the weight status of mother’s is positively associated with that of their children, particularly after age 2. These associations further strengthen the call for research regarding interventions and policies aimed at healthy weight promotion among mothers and their children collectively, rather than focusing on individuals in isolation.

Association Between Gestational Weight Gain and Delayed Onset of Lactogenesis II: a Systematic Review and Meta-Analysis.

Background: Gestational weight gain (GWG) may be associated with delayed onset of lactogenesis II (DOL II), but it is still unclear and controversial. Object: The study aims to evaluate the relationship between GWG and DOL II. Methods: A comprehensive search was performed in 10 electronic databases from inception to May 21, 2023, for studies that reported outcomes in breastfeeding. Data were extracted by two independent reviewers. A meta-analysis was conducted to calculate the pooled estimates of association using random-effect models with Review Manager (RevMan) software version 5.4. The primary outcome was the rate of DOL II. Results: In this study, 248,515 women were included in 16 eligible articles. Women with excessive GWG have a higher risk of DOL II (odds ratio [OR] = 1.28; 95% confidence interval [CI]: 1.15-1.43). Specifically, prepregnancy overweight and obese women with GWG above recommendations (OR = 3.01, 95% CI: 1.38-6.57) and underweight women with excessive GWG before pregnancy have a higher risk of DOL II (OR = 3.32, 95% CI: 1.69-6.53). Nonetheless, there is no distinction between women with inadequate GWG and those with adequate GWG in DOL II(OR = 1.08, 95% CI: 0.88-1.33). In addition, the women whose GWG is above the recommendations also tend to stop exclusive breastfeeding 1 month postpartum (OR = 0.82, 95% CI: 0.80-0.85). Conclusion: Excessive GWG has a negative influence on the timing of the onset of lactogenesis and exclusive breastfeeding within 1 month postpartum.

Deficiency of Energy and Nutrient and Gender Differences among Chinese Adults: China Nutrition and Health Survey (2015-2017).

Half of Chinese adults face the double burden of overweight/obesity and micronutrient deficiencies, and nearly 40% of them are severely overweight/obese or have micronutrient deficiencies. This study used the data from China Nutrition and Health Survey (CNHS) from 2015 to 2017 to estimate the prevalence of inadequate dietary micronutrient intake (including vitamin A, vitamin B1, vitamin B2, vitamin C, cCalcium, iron and sodium) in Chinese adults and further determine the differences in micronutrient intake by gender, age and BMI. A total of 61,768 subjects were included in this study, of which 33,262 (54%) were female. The intake of energy and all macronutrients decreased with age, and the intake was higher in men than in women. Inadequate energy intake occurs in adults of all ages. In terms of nutrient intake, women had a higher rate of insufficient carbohydrate intake than men in all age groups. Inadequate protein intake was more common in women aged 18-49 years (60.9%) than in men. Compared with women, men had a higher rate of vitamin B2 intake. Insufficient vitamin B3 intake was more common in women aged 18-49 years (35.6%), men aged 65-79 years (39.7%) and men aged 80 years and above (47.9%). In all age groups, insufficient vitamin C intake is higher in women than in men-up to 85.8 percent in women aged 80 years old and above. Compared with men in the same age group, insufficient intake of calcium and iron is more obvious in women. Women have significantly higher rates of inadequate intake of calcium, iron and sodium than men. In the analysis of correlations between BMI or demographic data and micronutrient intakes, the likelihood of micronutrient intakes being insufficient was higher in the central and western regions in all age groups compared to the eastern regions. The risk of insufficient micronutrient intake was higher in obese men and women aged 18-49 years and 50-64 years. Underweight and overweight women in the 65-79 age group were more likely to have inadequate micronutrient intake. Obese women over 80 years of age were less likely to have inadequate micronutrient intake. No significant difference was found between urban and rural areas for each age group.

Sustained underweight in rural areas and emergence of overweight in urban Ethiopian women: a multivariate analysis of EDHS data 2000–2016

A growing body of evidence indicates the emergence of overweight/obesity in developing countries before the battle against undernutrition has been won. We conducted this study to quantify the reduction of underweight and the emergence of overweight among Ethiopian women from 2000 to 2016 and evaluate factors explaining the progress. We used the four Ethiopian Demographic and Health Surveys (2000–2016) to analyze body mass index (BMI) trends among women. Data from 43,815 non-pregnant, non-puerperal reproductive-age women was used to evaluate the linear change in BMI and changes in the percentage of overweight and underweight over time. Using multivariate decomposition analysis of change in underweight and overweight percentages, we identified sources of change in BMI in the past 16 years of the survey periods. The BMI of Ethiopian reproductive-age women increased by 0.88 kg/m2 from 2000 to 2016. The increment was pronounced in urban areas with 1.46 kg/m2. There has been a significant reduction in underweight women since 2000 (p-value < 0.001), and 87.62% of the changes were attributed to behavioral changes toward weight management. And there was a significant upswing in overweight women from 2000 to 2016 (p-value < 0.001) as well. A compositional change of factors including region, women’s age, women’s educational status, religion, type of place of residence, and use of contraceptives contributed to 57.51% of the observed increment in the percentage of overweight women. A relatively slow decrease in underweight and an increment in overweight have been observed. This progress can be disaggregated into persistent underweight in the rural and poorest, and swift development of overweight in the urban and richest communities. Targeted nutrition interventions for both underweight and overweight women are mandatory. Nutritional interventions in Ethiopia should focus on behavioral change to reduce hunger and malnutrition as well as to avert the emergence of overweight or obesity in the affected communities.

The prevalence of gestational diabetes among underweight and normal weight women worldwide: a scoping review.

Gestational diabetes (GDM) affects nearly 15% of pregnancies worldwide and is increasing globally. While this growth is thought to be primarily from overweight and obesity, normal and underweight women are affected as well, particularly in low and middle-income countries. However, GDM in non-overweight women remains understudied. Thus, we examined the prevalence among normal and underweight women globally. A comprehensive literature search was performed in Ovid MEDLINE, Ovid EMBASE, and The Cochrane Library. Studies retrieved were screened for eligibility against predefined inclusion/exclusion criteria. Prevalence of GDM among women with normal and underweight body mass index (BMI) was extracted, and average prevalence was calculated globally, by World Health Organization region, and by country. Pregnancy outcomes were described when available. A total of 145 studies were included. The average global prevalence of GDM among non-overweight women (BMI <25 kg/m2) was 7.3% and among underweight women (BMI <18.5 kg/m2) was 5.0%. GDM prevalence in non-overweight women was highest in Asia (average 12.1%) and lowest in the African region (0.7%). The countries with the highest prevalence were Vietnam (21.1%), Finland (19.8%), Poland (19.3%), Bangladesh (18.65%), and China (17.7%). The average global prevalence of large for gestational age infants (LGA) born to non-overweight women with GDM was 9.9%, which is lower than the average prevalence in the general population with GDM (14%). GDM is more common than previously recognized in non-overweight women, particularly in Asia, but also in European countries. Non-overweight women with GDM had lower prevalence of LGA babies compared to prior reported prevalence in all women with GDM, though data on pregnancy outcomes was limited. These findings challenge guidelines that recommend restriction of weight gain for GDM management. Further research on the pathophysiology and complications of GDM in women who are not overweight should be urgently conducted to inform appropriate management guidelines and support optimal pregnancy outcomes.

Public Health Perspectives: Unveiling the Socio-Demographic Tapestry and Nutritional Wellness of Khatik Women in North-East Delhi

Introduction: The dietary intake pattern significantly impacts human health. Malnutrition remains a critical global issue,requiring comprehensive and on-going intervention efforts. Approximately one-third of the world's population faces some form of malnutrition, including underweight, overweight, or obesity. Proper nutrition is essential for individual health, particularly among women, emphasizing the importance of addressing nutritional needs effectively. This study investigates the relationship between nutritional status and socio-demographic/reproductive profiles of Khatik women in North East Delhi. Material and Methods: A cross-sectional investigation was carried out within the Khatik community of North East Delhi, involving data collection from 400 respondents. The current study examined the nutritional status using Body Mass Index (BMI) as a primary health indicator. Results: Results from the analysis indicated notable variations across BMI categories concerning age and reproductive variables. Specifically, as the age of the respondents increased, there was a greater likelihood of being overweight or obese. According to the study findings, overweight/obese women demonstrated a higher median (Median 21 IQR-19-22) consumption of full meals compared to both normal (Median 21, IQR-18-22) and underweight (Median 19, IQR-17-24) women. Similarly, underweight individuals (Median 3, IQR-2-5) exhibited a lower median intake of milk products compared to both normal weight (Median 4, IQR-3-6) and overweight (Median 4, IQR-3-6) respondents. Conclusion: The study reveals increasing overweight and obesity among Khatik women in Delhi, driven by factors like age, education, urban living, and economic status. Overweight or obese women tend to have more live births and conceptions compared to underweight and normal-weight women, highlighting disparities in reproductive outcomes across BMI categories.

Predicted Interventions for Improving the Nutritional Status of Vulnerable Groups of Uttarakhand: Evidence from Comparison between NFHS-5 and NFHS-4 Survey

Background: Nutritional status is an indicator of the overall well-being of a people. In view of this effect, a study was undertaken to compare the nutritional status of vulnerable groups (viz women of reproductive age group 15 to 49 years, pregnant women’s, adolescent girls and children aged 6 to 59 months of Uttarakhand. Methods: The data of the state under study was compared with national data. NFHS 4 and 5 data were used to analyse the health and nutritional trend of the identified groups over the reporting period of 5 years, to identify interventions and to help formulate policies for improving the nutritional status of the state. Result: The decreasing trend in the case of underweight women and the increasing trend in the percentage of overweight women were noted in every district. In the case of anemia among children aged 6 to 59 months, most of the districts had managed to reduce the prevalence of anemia in the last 5 years. Most of the districts have seen a decreased trend in anemia among pregnant women and among adolescent girls aged 15 to 19 years. The study reveals that the nutritional status of the vulnerable population of Uttarakhand has improved over the last five years, however, still, some districts (Tehri Garhwal, Dehradun, Chamoli, Pauri Garhwal, Uttarkashi and Rudraprayag) need special attention. A comparison of the improvement between the state and national data depicts that the state of Uttarakhand performed better than the nation in all categories except in reducing the cases of undernutrition in women. It may be postulated from the study that health and nutritional programmes have been effective in meeting their targets to a great extent. However, to further improve the condition of the population, district-specific developmental programmes need to be formulated, with a special focus on eradicating undernutrition among women.

Determinants of unhealthy BMI among women of childbearing age in Bangladesh

This paper investigated the determinants of unhealthy BMI categories, namely underweight, overweight, and obesity, for urban and rural women of childbearing age in Bangladesh. Multilevel nested logistic models were estimated using data from multiple waves (2004–18) of the Demographic and Health Surveys of Bangladesh. After controlling for community and regional effects, the underweight status showed an inverse relationship with years of education for urban and rural women. Conversely, the fitted model estimates revealed a positive association between overweight risk and education for both urban and rural women populations. However, the association between obesity and education was significant for only urban women. Employment status appeared to be negatively associated with the risks of being overweight and obese in both population groups. Moreover, the women were found less likely to be underweight and more likely to be overweight and obese when their household socio-economic status improved. Study findings have the potential to inform a wide range of interventions, policies and programs that simultaneously address the adverse consequences of underweight, overweight, and/obese population health conditions in rural and urban Bangladesh.

Optimal range of gestational weight gain for singleton pregnant women: a cohort study based on Chinese specific body mass index categories

BackgroundThe purpose was to explore the optimal proportion of GWG in Chinese singleton pregnant women according to Chinese specific body mass index (BMI) categories.MethodsA retrospective cohort study with 16,977 singleton pregnant women was conducted. Among the including subjects, 2/3 of which were randomly imported into the training set for calculating the optimal GWG ranges using the percentile method, the Odd Ratio (OR) method, and the combined risk curve method. And another third of the subjects were used to evaluate the GWG ranges obtained. The detection rate of adverse outcomes of pregnant women was used to evaluate the applicability of GWG obtained. The range corresponding to the lowest detection rate is the recommended GWG range in this study.ResultsAccording to the percentile method, the suitable GWG of pregnant women with underweight, normal weight, overweight or obesity before pregnancy were 12.0 ∼ 17.5 kg, 11.0 ∼ 17.0 kg, and 9.0 ∼ 15.5 kg, respectively. According to the OR method, the suitable GWG range were 11 ∼ 18 kg, 7 ∼ 11 kg, and 6 ∼ 8 kg, respectively. According to the combined risk curve method, the suitable GWG range were 11.2 ∼ 17.2 kg, 3.6 ∼ 11.5 kg, and − 5.2 ∼ 7.0 kg, respectively. When the GWG for different BMI categories were 11 ∼ 18 kg, 7 ∼ 11 kg, and 6 ∼ 8 kg, the pregnant women have the lowest detection rate of adverse maternal and infant outcomes.ConclusionsThe recommended GWG based on this study for underweight, normal, overweight or obese pregnant women were 11 ∼ 18 kg, 7 ∼ 11 kg, and 6 ∼ 8 kg, respectively.

Is there any materno- foetal risks in mothers with gestational weight gain (WHO &amp; IOM) based on their pre-pregnancy body mass indices? Our experience in a tertiary care teaching institution in North Kerala

: This research was done to learn the impact of pre-pregnancy BMI and gestational weight gain (GWG) on subsequent risks of adverse pregnancy outcomes in a tertiary care teaching institution in North Kerala, India. A descriptive study in a tertiary care teaching institution in Kozhikode, North Kerala. : 296 singleton pregnant women with BMI categorised as per Asian Standards and adverse maternal outcomes were looked out for. Pregnant women were underweight (82.8%) achieved less than recommended weight during pregnancy as compared to 18.4% obese mothers. Mothers with high BMI gained more than recommended weight during pregnancy as compared to the underweight and normal weight woman. GDM was 3.03 times(p=0.019)and Hypertensive disorders of pregnancy was 1.116 times more common in higher pre-pregnancy BMI mothers. In the present study, gestational weight gain had no impact on maternal anaemia, Gestational diabetes, Gestational hypertension, foetal growth restriction and rate of caesarean deliveries. A statistically significant positive correlation was obtained between pre-pregnancy BMI and baby weight, p&amp;#60;0.001. A statistically significant positive correlation was obtained between gestational weight gain and baby weight, p=0.005. Weight gain during pregnancy had no significant impact on maternal pregnancy outcomes and caesarean delivery.

Targeting strategies for balanced energy and protein (BEP) supplementation in pregnancy: study protocol for the TARGET-BEP cluster-randomized controlled trial in rural Bangladesh

BackgroundThe World Health Organization (WHO) recommends balanced energy and protein (BEP) supplementation be provided to all pregnant women living in undernourished populations, usually defined as having a prevalence > 20% of underweight women, to reduce the risk of stillbirths and small-for-gestational-age neonates. Few geographies meet this threshold, however, and a large proportion of undernourished women and those with inadequate gestational weight gain could miss benefiting from BEP. This study compares the effectiveness of individual targeting approaches for supplementation with micronutrient-fortified BEP vs. multiple micronutrient supplements (MMS) alone as control in pregnancy in improving birth outcomes.MethodsThe TARGET-BEP study is a four-arm, cluster-randomized controlled trial conducted in rural northwestern Bangladesh. Eligible participants are married women aged 15–35 years old identified early in pregnancy using a community-wide, monthly, urine-test-based pregnancy detection system. Beginning at 12–14 weeks of gestation, women in the study area comprising 240 predefined sectors are randomly assigned to one of four intervention arms, with sector serving as the unit of randomization. The interventions involving daily supplementation through end of pregnancy are as follows: (1) MMS (control); (2) BEP; (3) targeted BEP for those with pre-pregnancy body mass index (BMI) < 18.5 kg/m2 and MMS for others; (4) targeted BEP for those with pre-pregnancy BMI < 18.5 kg/m2, MMS for others, and women with inadequate gestational weight gain switched from MMS to BEP until the end of pregnancy. Primary outcomes include birth weight, low birth weight (< 2500 g), and small for gestational age, defined using the 10th percentile of the INTERGROWTH-21st reference, for live-born infants measured within 72 h of birth. Project-hired local female staff visit pregnant women monthly to deliver the assigned supplements, monitor adherence biweekly, and assess weight regularly during pregnancy. Trained data collectors conduct pregnancy outcome assessment and measure newborn anthropometry in the facility or home depending on the place of birth.DiscussionThis study will assess the effectiveness of targeted balanced energy and protein supplementation to improve birth outcomes among pregnant women in rural Bangladesh and similar settings.Trial registrationClinicalTrials.gov NCT05576207.

Preconception underweight impact on postnatal osteoporotic fracture: a retrospective cohort study using Japanese claims data

BackgroundUndernutrition and underweight are osteoporosis risk factors. Therefore, improving the health of underweight young women in Japan is an important medical issue. However, few studies have evaluated the association between being preconception underweight and postnatal osteoporotic fractures in young women.MethodsThis retrospective cohort study used a Japanese nationwide claims database (JMDC Inc.) to evaluate the effect of preconception underweight on the incidence of osteoporotic fracture within two years after delivery. Data from 16,684 mothers who delivered their first singleton babies between January 2006 and December 2020 were analysed. The combination of disease codes of fractures at sites associated with osteoporosis and medical procedures for fractures was defined as the incidence of osteoporotic fractures, whereas the body mass index (BMI) recorded 12–36 months before delivery was used as the exposure. We estimated the incidence of osteoporotic fractures by BMI category using a Kaplan–Meier curve and examined the fracture risk using Cox hazard regression analyses.ResultsFifty-one women (0.31%) were affected by osteoporotic fractures within two years of delivery. More than 80% of these were rib fractures, and approximately 65% of fractures occurred after the first year postpartum. Preconception underweight (BMI < 18.5 kg/m2) was significantly associated with the incidence of postpartum osteoporotic fractures. There was no significant association between low BMI and postnatal fractures, as analysed via multiple categorical logistic regression analysis.ConclusionAppropriate control of preconception weight might be critical to improving the postpartum quality of life, subsequent bone health, and neonatal care environment.

Associations between gestational weight gain and weight development of the offspring: Differences depending on maternal pre-pregnancy BMI

PurposeObesity rates are rising, and the gestational weight gain (GWG) of most women does not comply with current guidelines. This study assesses the association of pre-pregnancy BMI (ppBMI) and GWG with the child’s weight development and investigates whether associations with GWG differ depending on ppBMI.MethodsData were obtained from the cohort study LIFE Child (Germany), comprising 691 mother–child pairs. Children’s weight was followed until age five. Associations between maternal ppBMI, GWG, and children’s weight were evaluated using regression analyses.ResultsThe association between GWG and birth weight (BW) was significantly positive in normal and underweight (n/u) women (βGWG = 0.05, p < 0.01, 95% confidence interval (CI) 0.03—0.07), but not in women with overweight or obesity (o/o) (βGWG = 0.0002, p = 0.99, 95% CI −0.03 to 0.03). The risk of giving birth to an infant who was large for gestational age (LGA) increased with rising GWG in n/u women (OR = 1.6, p < 0.01, 95% CI 1.23—2.25). Women with o/o were at increased risk for a LGA baby regardless of GWG (OR = 3, p < 0.01, 95% CI 1.34—6.97). This trend persisted in the child’s weight development during the first 5 years of life.ConclusionWomen with o/o might increase their offspring’s risk for higher weight at birth and in early childhood. In n/u women, GWG might be the more influential factor. Women should strive for normal weight before conception and should be more attentive to GWG.
