Gestational Weight Gain and Pregnancy Outcomes in Relation to Body Mass Index in Asian Indian Women

Association of Gestational Weight Trajectories With Neonatal Outcomes Among Pregnant Slum-Dwelling Women, India

The influence of early pregnancy weight and gestational weight gain (GWG) on neonatal outcomes among Indian slum-dwellers remains understudied. A prospective cohort study summarised maternal weight trajectories using the longitudinal clustering technique and explored associations between these clusters and neonatal outcomes (low birthweight, small for gestational age [SGA] and preterm births) among 423 pregnant slum-dwelling women in Pune, India. Sociodemographic data, height and weight were measured at enrolment (< 12 weeks, 'early pregnancy'). Weight was additionally measured at 23 ± 1 ('mid-pregnancy'), 33 ± 1 ('late pregnancy'), 36-37 and 39-40 weeks. The mean age was 24.7 (95% CI, 23.3, 25.1) years and the mean BMI at enrolment was 22.3 (95% CI, 21.9, 22.7) kg/m2. Underweight women had the highest GWG rates and total GWG, while obese women had the lowest. Four clusters were identified: Cluster 1 (n = 124, 97% normal and overweight women, GWG rate: 0.27 (95% CI, 0.24, 0.30) kg/week early-late pregnancy) was the reference group. Women in Cluster 2 (n = 146, 93% underweight and normal weight women, GWG rate: 0.31 (95% CI, 0.28, 0.34) kg/week early-late pregnancy) had a higher risk of having SGA and preterm newborns and women in Cluster 3 (n = 68, 100% overweight and obese women, GWG rate: 0.17, 95% CI, 0.12, 0.22 kg/week early-late pregnancy) had a higher risk of having preterm newborns than Cluster 1. The women in Cluster 4 (n = 85, 100% underweight and normal weight, mean early-late pregnancy GWG rate of 0.47, 95% CI, 0.44, 0.50 kg/week) showed no higher risk of adverse neonatal outcomes. This study highlights the need to monitor both pre-pregnancy BMI and weight throughout pregnancy to enhance the possibility of favourable neonatal outcomes.

Overnutrition and associated factors among women of reproductive age in Sub-Saharan Africa: A hierarchical analysis of 2019-2023 standard demographic and health survey data

OBJECTIVES

Overnutrition, a leading cause of global mortality, has seen a significant rise in low- and middle-income countries, including sub-Saharan Africa. Despite emerging evidence linking overnutrition to non-communicable diseases, limited action has been taken to address this issue. While undernutrition studies have received more attention, research on overnutrition and women's health remains scarce in sub-Saharan Africa. Our study aims to assess the prevalence and associated factors of overnutrition among reproductive women in this region METHODS: We conducted a secondary analysis of 2019-2023 Demographic and Health Survey datasets in sub-Saharan Africa. Our study included a weighted sample of 65,161 women aged 15-49 y. Using a multilevel mixed-effects logistic regression model, we identified factors associated with overnutrition. The adjusted odds ratio, along with a 95% confidence interval and a significance level of p < 0.05, determined the statistical significance of the explanatory variables.

RESULTS

The pooled prevalence of overnutrition among women of reproductive age in sub-Saharan Africa was 34.79% (95% CI: 34.42-35.16). Specifically, the prevalence of overweight and obesity was 21.81% and 12.99%, respectively. Women's educational status, age, media use, household wealth, urbanization, community poverty, and country income level were significantly associated with higher odds of overnutrition.

CONCLUSIONS

The prevalence of overnutrition among women of reproductive age in sub-Saharan Africa is relatively high. Key factors associated with this issue include women's educational status, age, media utilization, household wealth, place of residence, community poverty level, and national income status. These multilevel determinants highlight the need for a comprehensive, evidence-based approach to address overnutrition in this population. Effective strategies should target individual behaviors while considering broader social, economic, and environmental contexts. Integrating overnutrition prevention into maternal and reproductive health services, as well as strengthening social protection measures, are recommended steps to tackle this growing challenge in sub-Saharan Africa.

Association of gestational weight gain rate with infant birth weight and cesarean delivery: A prospective cohort study in Nepal

Gestational weight gain (GWG) is linked to pregnancy outcomes, such as birth weight and delivery mode, though research in low-income countries like Nepal is limited. We examined the association of GWG rate with infant birth weight and cesarean delivery in a prospective cohort of 191 pregnant women in Nepal, using data collected from August 2018 to August 2019 at a peri-urban hospital in Dhulikhel. Participants included women with singleton, full-term live births, with GWG rate calculated from weight gain between the second and late pregnancy stages, divided by the weeks in between. GWG rate categories-adequate, inadequate, or excessive-were defined by pre-pregnancy Body Mass Index (BMI) specific to GWG recommendations from the 2009 Institute of Medicine report. Ethical approval was obtained from Institutional Review Board of Kathmandu University and Rutgers University. Statistical analyses in SPSS and Stata revealed that 52.4% of mothers exceeded the recommended GWG rate, particularly among overweight and obese women (0.4 ± 0.2 kg/week and 0.5 ± 0.2 kg/week, respectively). The average birth weight was 2964.9 ± 407.0 grams, with 12% of infants classified as low-birth-weight. Cesarean delivery was recorded in 45% of the women. After controlling for factors like age, education, ethnicity, occupation, parity and BMI, each 1 kg/week increase in GWG from the second to third trimester correlated with a 392-gram increase in birth weight (β = 391.9, 95%CI = 67.2-716.7, p = 0.01), while excessive GWG rate led to a 148-gram increase over adequate GWG rate (β = 148.1, 95%CI = 8.7-287.5, p = 0.03). However, GWG rate was not significantly linked to cesarean delivery. These findings suggest that maternal GWG rate positively affects infant birth weight but not cesarean delivery, underscoring the need for larger studies to explore GWG rate's effects on maternal and neonatal outcomes.

Double Burden of Malnutrition Among Pregnant Women in Rural Jharkhand: Evidence From a Cross-Sectional Study

INTRODUCTION

The nutritional status of pregnant women is a very important aspect of maternal and antenatal care, as malnutrition is detrimental to both the mother and the foetus. This study tries to assess the scale of the double burden of malnutrition in a rural setting in India.

METHODS

A cross-sectional study was conducted on 337 pregnant women to assess the nutritional status of pregnant women using Body Mass Index and dietary intake.

RESULTS

Overall, 21.4% of women were underweight, 14.8% were overweight, 0.9% were obese, and 62.9% of women were in the normal weight range based on Body Mass Index. Family type, dietary habits, and community practices were found to be significant determinants of nutritional status among pregnant women.

CONCLUSION

Nearly a third of the pregnant women were found to be malnourished, indicating the significant impact of the double burden of malnutrition. Lifestyle changes such as dietary improvement need to be emphasised to enhance maternal nutritional status during antenatal care.

Perceptual Factors Associated with Gestational Weight Gain: A Cross-Sectional Survey

PURPOSE

Recent years have seen an increase in the number of pregnant women whose weight gain during pregnancy exceeds the recommended range. This study was intended to determine the relationships among demographic attributes, key perceptual factors, and gestational weight gain (GWG).

METHODS

This cross-sectional study was conducted between April and July 2022. First-time pregnant women beyond 36 weeks of gestation who were recruited via social media completed an online survey. Data were analyzed using one-way ANOVA, chi-square test, and logistic regression, all performed using SPSS software.

RESULTS

Of the 369 participants, 63 (17.1%) exceeded the recommended GWG guidelines, while 148 (40.1%) fell within the recommended range, and the remaining 158 (42.8%) had inadequate GWG. Being overweight or obese before pregnancy significantly increased the risk of excessive GWG (p < .001). This risk was also significantly greater for women with low internal weight locus of control (OR = 0.58, 95% CI 0.41~0.82), high external weight locus of control (OR = 1.75, 95% CI 1.31~2.34), and negative body image (OR = 0.62, 95% CI 0.51~0.75).

CONCLUSION

The growing trend of excessive GWG among pregnant women is influenced by a combination of prepregnancy body mass index (BMI) and perceptual factors, including weight locus of control and body image. These findings underscore the need to implement weight management intervention strategies before pregnancy, taking into consideration BMI, and to enhance positive body image and internal locus of control.

Weight gain in pregnancy and impact of obesity on the obstetric outcome: A retrospective study in a secondary care hospital in South India

Objective

To evaluate the patterns of weight gain in pregnancy and the outcomes of pregnancy in overweight and obese mothers.

Materials and Methods

A retrospective cohort study was performed on 1,352 mothers between October 2020 and August 2021. All pregnant women who presented for antenatal checkups from 20 weeks or earlier, with a singleton pregnancy, were included in the study. Details such as comorbidities, total duration of labor, complications during labor, and neonatal complications were included.

Results

At the first antenatal visit, 16% of mothers were underweight, 51% of mothers were normal weight, and 33% of mothers were overweight or obese. Women with poor weight gain were two times more prone to give birth to a child with low birth weight than those with adequate weight gain. Excess weight gain in pregnancy in women with a normal body mass index (BMI) had an association with the development of pre-eclampsia. The odds of overweight/obese pregnant women developing gestational diabetes mellitus (GDM) were 2.1 times higher than in pregnant women with normal BMI. The odds of pregnant overweight/obese women undergoing cesarean section were 1.6 times higher than in pregnant women with normal BMI.

Conclusion

Overweight/obese pregnant women had increased odds of developing GDM and undergoing a cesarean section. Excess weight gain was also seen in overweight/obese women. It is therefore important for physicians to educate women on acceptable weight gain during their pregnancy.

Gestational weight gain and body mass index in Asian Indian women: Impact of timing and amount on fetomaternal outcomes

Background

The aim of the study was to describe pre-pregnancy body mass index (BMI), total gestational weight gain (TGWG), and trimester-specific gestational weight gain (TSGWG) among Asian Indians and examine their association with adverse fetomaternal outcomes (AFMO).

Methods

Using a prospective cohort study design, 557 pregnant women were recruited in the first trimester and followed up until delivery. Maternal BMI, TGWG and TSGWG were assessed and categorised according to the World Health Organisation (WHO) Asia Pacific BMI guidelines and the Institute of Medicine (IOM) recommendations, respectively. Maternal clinical characteristics and pregnancy and neonatal outcomes were assessed to predict AFMO. Logistic regression models in univariate and multivariate analysis were performed to estimate the odds ratios (OR) and 95% confidence intervals (CI).

Results

The median BMI was 23.5 kg/m2. Moreover, 24.6% were overweight and 31.2% were obese, according to WHO Asia Pacific BMI cut points. The mean TGWG was 10.8 ± 1.9 kg and the mean TSGWG in the first, second and third trimesters were 1.7 ± 0.7 kg, 4.3 ± 1.1 kg and 4.8 ± 1.2 kg, respectively. We found a significant association of BMI, TGWG and TSGWG with various AFMO. Furthermore, excess third-trimester GWG has been demonstrated as a predictor of adverse maternal outcomes like hypertension and gestational diabetes mellitus.

Conclusions

Our study reinforces the importance of optimal BMI and TGWG and further emphasises on assessment of TSGWG, which allows for early diagnosis of weight deviations, when prompt interventions can still improve pregnancy outcomes. We also suggest the adoption of BMI categories and GWG recommendations, specific to the socio-demographic characteristics of the population, to optimise the prevention, early diagnosis, and timely management of AFMO.

Spatial clustering of overweight/obesity among women in India: Insights from the latest National Family Health Survey

BACKGROUND

Overweight/obesity has become global health concern with increasing prevalence. This study examined district-level disparities and spatial clustering of overweight/obesity among women of reproductive age (WRA) in India using the latest National Family Health Survey-5 (2019-2021) data.

METHOD

Information of 623,656 women aged 15 to 49 from the NFHS-5 (2019-2021) were analysed in this study. The outcome variable was BMI as classified by the world health organisation (WHO). Utilising Global Moran's I, Anselin's Local Moran's I, and spatial regression models spatial clustering and associated factors were analysed.

RESULT

The study found that 24% (95% CI: 23.8-24.3) of WRA in India were overweight/obese in 2019-21. The prevalence was greatest in Punjab (41%) and lowest in Meghalaya (11%). Additionally, the Global Moran's I value for the outcome variable was 0.73, indicating a positive spatial autocorrelation in the overweight/obesity. Districts of Tamil Nadu, Andhra Pradesh, Karnataka, Kerala, Telangana, Punjab, Himachal Pradesh, Jammu & Kashmir, Haryana, and Delhi were hotspots of overweight/obesity. Several factors of overweight/obesity among WRA were identified, including place of residence (β: 0.034, p: 0.011), parity (β: 0.322, p: 0.002), social group (β: -0.031, p: 0.016), religion (β: -0.044, p: <0.001), household wealth status (β: 0.184, p: <0.001), mass-media exposure (β: 0.056, p: 0.031), and diabetes (β: 0.680, p: <0.001).

CONCLUSION

The study emphasizes the importance of targeted interventions and region-specific strategies, while also stressing the need to address associated factors to develop effective public health initiatives aimed at reducing overweight/obesity prevalence among WRA in India.

Spatial distribution and associated factors of co-occurrence of overweight/obesity and Anemia among women in the reproductive age in sub-Saharan Africa: A multilevel analysis, DHS 2016-2021

BACKGROUND

Overweight/obesity is one of the major public health problems that affect both developed and developing nations. The co-occurrence of overweight/obesity and anemia is thought to be largely preventable if detected early. To date, no spatial analyses have been performed to identify areas of hotspots for the co-occurrence of overweight/obesity and anemia among reproductive women in sub-Saharan Africa. Therefore, this study aimed to assess the spatial distribution and associated factors of the co-occurrence of overweight/obesity and anemia among women of reproductive age.

METHODS

Data for the study were drawn from the Demographic and Health Survey, a nationally representative cross-sectional survey conducted in the era of Sustainable Development Goals, in which the World Health Assembly decided and planned to cease all forms of malnutrition by 2030. Seventeen sub-Saharan African countries and a total weighted sample of 108,161 reproductive women (15-49 years) were included in our study. The data extraction, recoding and analysis were done using STATA V.17. For the spatial analysis (autocorrelation, hot-spot and interpolation), ArcGIS version 10.7 software, and for the SaTScan analysis, SaTScan version 10.1 software was used. Descriptive statistics were presented using frequency tables and percentages. We employed multilevel logistic regression to investigate associated factors. In the multivariable analysis, variables with a p-value of ≤0.05 are considered as a significant factor associated with co-occurrence of overweight/obesity and anemia among women aged 15-49 years.

RESULTS

The overall co-occurrence of overweight/obesity and anemia among women in sub-Saharan Africa was 12% (95%CI: 9-14%). The spatial analysis revealed that the co-occurrence of overweight/obesity and anemia among women significantly varied across sub-Saharan Africa. (Global Moran's I = 0.583163, p<0.001). In the spatial window, the primary-cluster was located in Liberia, Guinea, Gambia, Sira Leon, Mauritania, Mali, Cameron and Nigeria with a Log-Likelihood Ratio (LRR) of 1687.30, and Relative Risk (RR) of 2.58 at a p-value < 0.001. In multilevel analysis, women aged 25-34 years (AOR = 1.91, 95%CI: 1.78, 2.04), women aged 35-49 years (AOR = 2.96, 95% CI: 2.76, 3.17), married (AOR = 1.36, 95% CI: 1.27, 1.46), widowed (AOR = 1.22, 95%CI: 1.06, 1.40), divorced (AOR = 1.36, 95% CI: 1.23, 1.50), media exposure (AOR = 1.31, 95%CI: 1.23, 1.39), middle income (AOR = 1.19, 95%CI: 1.11, 1.28), high income/rich (AOR = 1.36, 95%CI: 1.26, 1.46), not working (AOR = 1.13, 95% CI:1.07, 1.19), traditional contraceptive utilization (AOR = 1.39, 95%CI: 1.23, 1.58) and no contraceptive use (AOR = 1.27, 95%CI: 1.20, 1.56), and no health insurance coverage (AOR = 1.36, 95%CI: 1.25, 1.49), were individual level significant variables. From community-level variables urban residence (AOR = 1.61, 95%CI: 1.50, 1.73), lower middle-income country (AOR = 2.50, 95%CI: 2.34, 2.66) and upper middle-income country (AOR = 2.87, 95%CI: 2.47, 3.34), were significantly associated with higher odds of co-occurrence of overweight/ obesity and anemia.

CONCLUSION AND RECOMMENDATIONS

The spatial distribution of the co-occurrence of overweight/obesity and anemia was significantly varied across the sub-Saharan African country. Both individual and community-level factors were significantly associated with the co-occurrence of overweight/obesity and anemia. Therefore, public health programmers and other stalk holders who are involved in maternal healthcare should work together and give priority to hotspot areas of co-occurrence in sub-Saharan Africa.

High pre-pregnancy body mass index and gestational weight gain among women belonging to upper SES from Delhi, India

Background and objective

With increase in prevalence of obesity and an increasing trend in the birth of macrosomic infants, Institute of Medicine (IOM) guidelines pertaining to optimal gestational weight gain (GWG) required for positive pregnancy outcome were revised in 1990 and 2009. Since, in the Indian scenario, no recommendations exist for optimum GWG for obese (OB) and overweight (OW) women, we assessed the pattern of GWG w.r.t Institute of Medicine (IOM), 2009 among the subjects with different body mass index (BMI).

Study design

Present data were a part of a longitudinal observational study wherein, 312 pregnant women (≤12th week of gestation) attending private antenatal clinics were followed till term and their weight was monitored regularly at pre-determined intervals i.e., 12th-14th, 18th-20th, 24th-26th, 30th-32nd, 36th + week of gestation and compared w.r.t IOM guidelines 2009.

Results

66.37 %, 57.89 % and 11.69 % of OB, OW and normal weight (NW) subjects respectively had weight gain exceeding their GWG limits. About 5 %,10.53 %, 33.77 % of OB, OW and NW subjects respectively had gained weight less than GWG limits (p = 0.000***).

Conclusion

An increase in GWG inadequacy with increase in BMI and pronounced variations in GWG among OB and OW subjects underscore the necessity to monitor GWG especially among the subjects with high BMI.

A multilevel analysis of the triple burden of malnutrition in Indonesia: trends and determinants from repeated cross-sectional surveys

BACKGROUND

Although child malnutrition has been reducing, the coexistence in mothers and children of various forms of malnutrition has continued to rise around the world. In the Indonesian context, a knowledge gap exists on the coexistence of multiple malnutrition burdens. This study examines trends in the coexistence of the triple burden of malnutrition (TBM) among mother-child pairs living in the same house and explores multilevel (individual, household, and community) factors associated with TBM in Indonesia.

METHODS

We used data from the 2013 and 2018 Indonesia Basic Health Research, the nationally representative survey of the Indonesian population, as repeated cross-sectional surveys. Study samples were mothers and children (0-59 months old), who resided in the same household and indicated by the same identifier number. The anthropometric measurements of the mothers and children, and the hemoglobin levels of the children were collected. We employed a multilevel mixed-effects model to consider the hierarchical data structure. The model captured the role of cluster, district, provincial differences, and the individual, household, community-level, and TBM status characteristics.

RESULTS

Of 3,891 mother-child pairs analyzed, 24.9% experienced TBM. Girls had 63% higher odds than boys of TBM (aOR: 1.63; 95% CI: 1.30 to 2.03). Significantly lower odds were found in children of mothers who had a gestational age lower than 37 weeks (aOR: 0.72; 95% CI: 0.55 to 0.94). At the household level, children with a father who had a high-school, primary-school, or no school education had significantly higher odds of TBM than children of fathers who had graduated from academy. Children of mothers who visited Antenatal Care (ANC) no more than 6 times had significantly lower odds (aOR: 0.65; 95% CI: 0.47 to 0.88). Children of mothers who consumed Iron and Folic Acid (IFA) supplements had significantly lower odds.

CONCLUSION

TBM is related to characteristics at not just the individual level but also the family and community levels. To achieve significant outcomes, integrated nutrition interventions in Indonesia should also consider family and community factors.

Perinatal outcomes among Indian-born mothers in Australia

OBJECTIVE

To examine the incidence of adverse perinatal outcomes and the risk of adverse perinatal outcomes for Indian-born mothers compared to other mothers living and giving birth in Australia.

DESIGN, SETTING AND PARTICIPANTS

This retrospective cohort study was designed to investigate all births in Australia in 2012 and those in the Monash Health Birthing Outcomes System (BOS) 2014 to Indian-born mothers in Australia. Data sets were analysed involving descriptive statistics using Statistical Package for Social Sciences (SPSS vs. 23).

RESULTS

Indian-born mothers in Australia are at increased risk of induced labour, emergency caesarean section, very preterm birth (20-27 weeks), babies with low to very low birth weight, and low Apgar score (0-2) at 5 min, gestational diabetes, hypothyroidism, iron deficiency anaemia and vitamin B12 deficiencies compared to other mothers giving birth in Australia. This is despite a range of protective factors (25-34 years, married, nonsmokers, and a BMI < 30) that would normally be expected to reduce the risk of adverse perinatal outcomes for mothers giving birth in a developed country.

CONCLUSION

In the absence of many of the recognized maternal risk factors, Indian-born mothers continue to face increased risk of adverse perinatal outcomes, despite access to high quality maternity care in Australia. Recommendations arising from this study include the need for an intervention study to identify maternal risk factors for Indian-born mothers in mid to late pregnancy that contribute to the risk for very preterm birth and low birth weight.

District-level heterogeneity in overweight or obesity among women of reproductive age: A geo-spatial analysis in India

BACKGROUND

Globally by 2030, 38% of the world's population would be overweight, and another 20% would be obese. This has led to rising concerns regarding how swiftly and substantially the world is moving towards this epidemic of "globesity". India too is facing an increased burden of overweight and obese population. The changing dietary patterns are significantly associated with the increasing prevalence of overweight/obesity and related complications, especially among women. Hence, the present study aims to observe the spatial patterns of overweight or obesity among women in reproductive age group in India and factors associated with it.

METHODS

The study analyzed data from a cross-sectional nationwide household survey, i.e. National Family Health Survey (NFHS-4), 2015-16. The primary outcome variable of this study was overweight/obesity among reproductive-age women, which was measured through the body mass index (BMI) of the women. Bivariate and multivariate logistic regression analysis was used to analyze the data. Additionally, for spatial analysis in terms of overweight/obesity among women in India, univariate and bivariate Moran's I index measurements were used along with the usage of spatial regression models.

RESULTS

The value of spatial-autocorrelation for overweight or obese was 0.64, which depicts the moderately high prevalence of the overweight/obesity coverage over districts of India. The overall prevalence overweight/obesity among women in India is around 25% and higher proportion of women from urban areas (37.8%), and non-poor (33.4%) economic group reported to be overweight or obese. From spatial lag model, the lag coefficient was found to be 0.28, implying that a change in the prevalence of overweight/obesity among women in a certain district may statistically lag the prevalence of overweight/obesity by 28% in the neighbouring districts. There were significantly high clustering of overweight/obese women and non-poor wealth quintiles in 132 districts, mainly from states of Punjab, Haryana, Gujarat, Maharashtra, Kerala, Tamil Nadu, Karnataka and Andhra Pradesh. Additionally, there was high-high clustering of overweight/obese women and those who ever had caesarean in 82 districts, mostly from Kerala, Tamil Nadu, Andhra Pradesh and Karnataka.

CONCLUSION

The spatial patterns on the prevalence of overweight and obesity in India show that the women belonging to the southern states' districts are more overweight or obese in comparison to other states. The determinants like older age, higher education, urban residence, higher economic status are the key factors contributing to the prevalence of overweight or obesity among women in the reproductive age group. The study concludes and recommends an urgent need of interventions catering to urban women belonging to higher socio-economic status, to reduce the risks of health consequences due to overweight and obesity.

Double burden of malnutrition and its associated factors among women in low and middle income countries: findings from 52 nationally representative data

BACKGROUND

Double burden of malnutrition (DBM) is an emerging global public health problem. The United Nations member states adopted eradicating all forms of malnutrition as an integral component of the global agenda. However, there is evidence of a high burden of undernutrition among women and rising rates of overweight and obesity, especially in low and middle income countries (LMICs). Therefore, this study aimed to investigate the prevalence and associated factors of underweight, overweight, and obesity among women of reproductive age in LMICs.

METHODS

Data for the study were drawn from a recent 52 Demographic and Health Surveys (DHS) conducted in LMICS. We included a sample of 1,099,187 women of reproductive age. A multilevel multinomial logistic regression model was used to identify factors associated with DBM. Adjusted relative risk ratio (RRR) with a 95% Confidence Interval (CI) was reported to show an association.

RESULTS

The prevalence of underweight, overweight, and obesity in LMICs among women of reproductive age was 15.2% (95% CI: 15.1-15.3), 19.0% (95% CI: 18.9- 19.1), and 9.1% (95% CI: 9.0-9.2), respectively. This study found that women aged 24-34 years, aged ≥ 35 years, with primary, secondary, and above educational level, from wealthy households, using modern contraceptives, exposed to media (radio and television), and with high parity (more than one birth) were more likely to have overweight and obesity and less likely to have underweight. Moreover, the risk of having obesity (RRR = 0.59; 95% CI = 0.58-0.60 and overweight (RRR = 0.78; 95% CI = 0.77-0.79) were lower among rural women, while the risk of being underweight was (RRR = 1.13; 95% CI = 1.11-1.15) higher among rural women compared to urban women.

CONCLUSION

The prevalence of underweight, overweight, and obesity was high among women of reproductive age in LMICs. Underweight, overweight, and obesity are influenced by sociodemographic, socioeconomic, and behavioral-related factors. This study shows that, in order to achieve Sustainable Development Goal 2, a multifaceted intervention approach should be considered to prevent both forms of malnutrition in women of reproductive age. This can be achieved by raising awareness and promoting healthy behaviors such as healthy eating and physical activity, especially among educated women, women from wealthy households, and women exposed to the media.

Triple burden of malnutrition among mother-child pairs in low-income and middle-income countries: a cross-sectional study

OBJECTIVE

This study aimed to assess the prevalence and determinants of the triple burden of malnutrition among mother-child pairs in low-income and middle-income countries.

DESIGN

Cross-sectional study.

SETTING

Low-income and middle-income countries.

PARTICIPANTS

Women and children.

PRIMARY OUTCOME

Triple burden of malnutrition (overweight/obese mother with undernourished and anaemic under 5 years child).

METHODS

Data for this study were drawn from recent 22 low-income and middle-income countries Demographic and Health Surveys. A total weighted sample of 116 795 mother-child pairs was included in the study. STATA V.14.2 was used to clean, code and analyse the data. Multilevel logistic regression was employed to identify factors associated with the problem. Adjusted OR (AOR) with 95% CI and a p<0.05 was reported to indicate statistical association. Model fitness and comparison were done using intraclass correlation coefficient, median OR, proportional change in variance and deviance.

RESULT

The pooled prevalence of the triple burden of malnutrition among mother-child pairs was 11.39%. It showed statistically significant positive associations with mothers aged ≥35 years (AOR 2.25, 95% CI 2.08 to 2.44), family size >10 (AOR 1.17, 95% CI 1.08 to 1.26), delivery by caesarean section (AOR 1.93, 95% CI 1.83 to 2.03), the richest household (AOR 1.72, 95% CI 1.56 to 1.88), grand multiparous (AOR 1.62, 95% CI 1.46 to 1.81), age of child 36-47 months (AOR 1.77, 95% CI 1.64 to 1.90), at a p<0.05. Whereas breast feeding (AOR 0.94, 95% CI 0.89 to 0.99), married mothers (AOR 0.87, 95% CI 0.78 to 0.96), female children (AOR 0.88, 95% CI 0.84 to 0.92), improved toilet (AOR 0.23, 95% CI 0.17 to 0.29), improved source of drinking water (AOR 0.28, 95% CI 0.21 to 0.35), rural residents (AOR 0.66, 95% CI 0.62 to 0.69) had a contrasting relationship with the triple burden of malnutrition.

CONCLUSION

About 1 out of 10 households suffer from the triple burden of malnutrition in low-income and middle-income countries. This study revealed that several maternal, child, household and community-level factors have a significant impact on the triple burden of malnutrition among mother-child pairs.

Lipid bands of approx. 1740 cm-1 as spectral biomarkers and image of tissue oxidative stress

Studies with the use of FTIR and FTR methods to find spectroscopic biomarkers within the 1740 cm^-1 band of pathological tissues found that oxidative stress, including damage to epidermis and structural changes in pathological amnion and placenta tissue, are associated with the occurrence of products of lipid peroxidation and have impact on fluidity and transport function of membranes. In particular, the findings show that the absence of a marker lipid band of approx. 1743 cm^-1 and the occurrence of a minimum of 1764 cm^-1 (FTIR) and 1734 cm^-1 (FTR) testify to the integrity and absence of damage in the allogeneic dermis, while the presence the 1743 or 1747 cm^-1 bands indicates denaturation of the thermally or electrically burned epidermis. The absence of a marker lipid band of approx. 1736-1740 cm^-1 for a healthy placental and amniotic tissue and the presence of a band of 1740 cm^-1 indicate placental gestosis, while the presence of a band of 1742 cm^-1 indicates hypotrophy. The 1738 cm^-1 bands indicate amniotic macrosomia. Structural changes caused by tissue modification with antioxidants, which were observed on individual samples: the L-ascorbic acid (presence of a lipid band marker at a frequency of 1755 cm^-1), sodium ascorbate (disappearance of the marker band), orthosilicic acid (disappearance or decrease in the intensity of the marker band with a decrease in the concentration of the modifier), as well as graphene oxide (separation of the marker lipid band of 1755 cm^-1), inform us about the effect of modifiers on the tissue repair process. The studies also tracked spectral changes identified in serum. Withing the range of the lipid band and the amide I and II bands (α → β conversion), there are clear differences between normal and pathological serum lyophilisates and a sample analyzed from the solution.

Impact of prepregnancy body mass index on adverse pregnancy outcomes: analysis from the Longitudinal Indian Family hEalth cohort study

BACKGROUND

Both high and low maternal prepregnancy body mass index can lead to suboptimal fetal growth and risk of pregnancy complications. In developed countries, nearly half of all women of childbearing age are either overweight or obese, and most data linking maternal body mass index and adverse pregnancy complications are limited to these populations.

OBJECTIVE

This study aimed to prospectively evaluate the relationships between prepregnancy body mass index and adverse pregnancy outcomes using the Longitudinal Indian Family hEalth (LIFE) study.

STUDY DESIGN

We modeled the relationships between prepregnancy body mass index and adverse pregnancy outcomes such as low birthweight, preterm birth, cesarean delivery, intrauterine growth restriction, miscarriage, and fetal death among 675 women aged 15 to 35 years with singleton pregnancies in the Longitudinal Indian Family hEalth study, a population-based prospective pregnancy cohort study conducted in Telangana, India. Prepregnancy body mass index was calculated as weight in kilograms divided by height in meters squared and was classified into 4 categories using the World Health Organization recommendations for Asian adults. Prepregnancy body mass index was assessed at a mean of 12.3 months before pregnancy. Odds ratios and 95% confidence intervals of adverse pregnancy outcomes were modeled and adjusted for confounders.

RESULTS

Obese women had a 3-fold increased risk of cesarean delivery (odds ratio, 3.13; 95% confidence interval, 1.56-6.29) compared with normal-weight women. Those who were overweight also had a marginally increased risk of cesarean delivery, albeit not statistically significant (odds ratio, 1.17; 95% confidence interval, 0.61-2.24). Underweight women had a modestly increased risk of low birthweight, compared with normal-weight women (odds ratio, 1.12; 95% confidence interval, 0.71-1.77), although results were not significant. Conversely, obese (odds ratio, 0.71; 95% confidence interval, 0.28-1.77) and overweight (odds ratio, 0.61; 95% confidence interval, 0.24-1.51) women had a marginally decreased risk of low birthweight.

CONCLUSION

Our data suggest that women with elevated prepregnancy body mass index may have a higher risk of adverse pregnancy outcomes, especially cesarean delivery. Although this study has limited generalizability, our findings are generalizable to rural to periurban regions of India. Further studies exploring the translatability of these findings to other populations are needed. In addition, targeted prepregnancy intervention studies and programs that include counseling on optimization of preconception health and lifestyle modification for improvement of subsequent pregnancy outcomes among overweight and obese women are needed.

Gestational weight gain in the REVAMP pregnancy cohort in Western India: Comparison with international and national references

Objective

To determine the trimester specific gestational weight gain (GWG) in a population of pregnant women from Western India and compare it with the Intergrowth-21st international and an Indian reference (GARBH-Ini cohort-Group for Advanced Research on BirtH outcomes).

Study design

A prospective longitudinal observational study was undertaken in Pune, West India and data for gestational weight gain was collected [the REVAMP study (Research Exploring Various Aspects and Mechanisms in Preeclampsia)]. Generalized Additive Models for Location, Scale and Shape method (GAMLSS model) were used to create GWG centile curves according to gestational age, stratified by BMI at recruitment (n = 640) and compared with Intergrowth-21st reference and GARBH-Ini cohort. Multivariable regression analysis was used to evaluate the relationship between GWG and antenatal risk factors.

Results

The median GWG was 1.68, 5.80, 7.06, and 11.56 kg at gestational ages 18, 26, 30, and 40 weeks, respectively. In our study, pregnant women gained less weight throughout pregnancy compared to Intergrowth-21st study, but more weight compared to the GARBH-Ini cohort centile curves in all the BMI categories. GWG in overweight/obese women (BMI ≥ 25) was significantly lower (<0.001) as compared to underweight (BMI < 18.5), or normal weight women (BMI ≥ 18.5 and <25). The median GWG at 40 weeks in underweight, normal and overweight/obese women was 13.18, 11.74, and 10.48 kg, respectively. Higher maternal BMI, older maternal age, higher parity and higher hemoglobin concentrations were associated with lower GWG, while taller maternal height was associated with greater GWG.

Conclusion

GWG of Indian women is lower than the prescriptive standards of the Intergrowth charts.

Association Between Early Pregnancy Body Mass Index and Gestational Weight Gain in Relation to Neonatal Birth Weight

Introduction: Maternal early pregnancy body mass index (BMI) and gestational weight gain (GWG) strongly correlate with pregnancy outcomes. Gestational hypertension and diabetes have been associated with overweight and obesity in pregnancy. A low pre-pregnancy BMI has been associated with low birth weight and preterm birth.

Method: This observational study was carried out from November 2018 to July 2020 in a tertiary care hospital in South India with a sample size of 100. Pregnant women with uncomplicated singleton pregnancies booked for regular antenatal care by 10 weeks of gestation were included in the study. During the participants' antenatal check-ups, detailed history and examinations were made. The weight of the participants was recorded at every antenatal check-up. Information about the gestational age at delivery and the birth weight of the neonates were collected following delivery.

Results: The mean age of women was 25.83 + 2.74 years. Of women who delivered low birth weight neonates (<2.5 kg), 86% had GWG below the Institute of Medicine (IOM) recommendation. A total of 57% of women with normal early pregnancy BMI and 67% of obese women had GWG within the IOM recommendation. Early pregnancy BMI had a positive correlation with neonatal birth weight (r (98) = 0.779, p = 0.001). Of the underweight pregnant women, 72% gave birth to small for gestational age (SGA) babies, and 97% percent of normal early pregnancy BMI women delivered neonates with normal weight for gestational age. A total of 33% of overweight and 50% of obese women had large for gestational age (LGA) babies.

Conclusion: Results from this study suggest that maternal early pregnancy BMI is more strongly associated with neonatal birth weight than GWG. Therefore, early pregnancy BMI may be an important focus for counseling during pregnancy.

Inequalities in overweight and obesity among reproductive age group women in India: evidence from National Family Health Survey (2015-16)

Background

In developing nations like India, fertility and mortality have decreased, and diseases related to lifestyle have become more common. Females in India are more prone to being overweight and obese than their male counterparts, more specifically in affluent families than the poor ones. Understanding the overweight and obesity trend may help develop feasible public health interventions to reduce the burden of obesity and associated adverse health outcomes.

Methods

The study utilizes the fourth round of the National Family Health Survey (NFHS-4), 2015–16. Descriptive statistics, bivariate and multivariate analysis was used to check the significant relationship between overweight and obesity, and other background characteristics. Income-related inequality in overweight and obesity among women was quantified by the concentration index and the concentration curve. Further, Wagstaff decomposition analysis was done to decompose the concentration index, into the contributions of each factor to the income-related inequalities.

Results

Overweight & obesity among women had a significant positive association with their age and educational level. The odds of overweight and obesity were 57% more likely among women who ever had any caesarean births than those who did not [AOR: 1.57; CI: 1.53–1.62]. The likelihood of overweight and obesity was 4.31 times more likely among women who belonged to richest [AOR: 5.84; CI: 5.61–6.08] wealth quintile, than those who belonged to poor wealth quintile. Women who ever terminated the pregnancy had 20% higher risk of overweight and obesity than those who did not [AOR: 1.20; CI: 1.17–1.22]. The concentration of overweight and obesity among women was mostly in rich households of all the Indian states and union territories. Among the geographical regions of India, the highest inequality was witnessed in Eastern India (0.41), followed by Central India (0.36).

Conclusion

The study results also reveal a huge proportion of women belonging to the BMI categories of non-normal, which is a concern and can increase the risks of developing non-communicable diseases. Hence, the study concludes and recommends an urgent need of interventions catering to urban women belonging to higher socio-economic status which can reduce the risks of health consequences due to overweight and obesity. Development nutrition-specific as well as sensitive interventions can be done for mobilization of local resources that addresses the multiple issues under which a woman is overweight or obese.

Gestational weight gain and pregnancy outcomes: Findings from North Indian pregnancy cohort

Despite the high prevalence of inadequate gestational weight gain (GWG) and adverse pregnancy outcomes, very few studies have addressed the association between GWG and pregnancy outcomes in South Asia. Our objectives were to estimate the prevalence of GWG during the second and third trimesters within, below and above the Institute of Medicine (IOM) guidelines, and to estimate the effect of the rate and adequacy of GWG on gestational age at the time of delivery, weight, length, length‐for‐age z‐score (LAZ), weight‐for‐length z‐score (WLZ) and adverse pregnancy outcomes, namely prematurity, small‐for‐gestational age (SGA), low birth weight (LBW), stunting and wasting at birth. We analysed data from the intervention group of the Women and Infants Integrated Interventions for Growth Study (WINGS), which is an ongoing individually randomized factorial design study. Of the 1332 women analysed, 40.2% [95% confidence interval (CI) 37.5 to 42.8] had GWG below the IOM guidelines. For every 100‐g/week increase in GWG, birth weight increased by 61 g, birth length by 0.16 cm, LAZ score by 0.08 SD, WLZ score by 0.14 SD, and gestational age at birth by 0.48 days. Women with GWG below the IOM guidelines had a higher relative risk of adverse pregnancy outcomes (44% for LBW, 27% for SGA, 32% for stunting and 42% for wasting at birth) than women who had GWG within the IOM guidelines, except for prematurity. The association between GWG and LAZ scores at birth was modified by early pregnancy body mass index (BMI). GWG is a strong predictor of newborn anthropometric outcomes and duration of gestation but not prematurity.

Population estimates and determinants of severe maternal thinness in India

OBJECTIVE

To examine prevalence, risk factors, and consequences of maternal severe thinness in India.

METHODS

This mixed methods study analyzed data from the Indian National Family Health Survey (NFHS)-4 (2015-2016) to estimate the prevalence of and risk factors for severe thinness, followed by a desk review of literature from India.

RESULTS

Prevalence of severe thinness (defined by World Health Organization as body mass index [BMI] <16 in adult and BMI for age Z score < -2 SD in adolescents) was higher among pregnant adolescents (4.3%) compared with pregnant adult women (1.9%) and among postpartum adolescent women (6.3%) than postpartum adult women (2.4%) 2-6 months after delivery. Identified research studies showed prevalence of 4%-12% in pregnant women. Only 13/640 districts had at least three cases of severely thin pregnant women; others had lower numbers. Three or more postpartum women aged ≥20 years were severely thin in 32 districts. Among pregnant adolescents, earlier parity increased odds (OR 1.96; 95% CI, 1.18-3.27) of severe thinness. Access to household toilet facility reduced odds (OR 0.72; 95% CI, 0.52-0.99]. Among mothers aged ≥20 years, increasing education level was associated with decreasing odds of severe thinness (secondary: OR 0.74; 95% CI, 0.57-0.96 and Higher: OR 0.54; 95% CI, 0.32-0.91, compared with no education); household wealth and caste were also associated with severe thinness.

CONCLUSION

This paper reveals the geographic pockets that need priority focus for managing severe thinness among pregnant women and mothers in India to limit the immediate and intergenerational adverse consequences emanating from these deprivations.

Gestational weight gain trajectories in GARBH-Ini pregnancy cohort in North India and a comparative analysis with global references

BACKGROUND

To describe the pattern of gestational weight gain (GWG), derive reference centiles for GWG specific to North Indian population, and to compare the weight gain across different periods of gestation with the INTERGROWTH-21st reference.

METHODS

A prospective pregnancy (GARBH-Ini) cohort was initiated and followed between May 2015 and June 2019 in a district hospital, Gurguram, North India. GWG centile curves were modelled by Generalized Additive Models for Location, Scale and Shape method (n = 2844) and compared with INTERGROWTH-21st reference. The independent association of GWG with biological and social predictors was assessed using multivariable regression analysis.

RESULTS

Percentiles (3rd, 10th, 50th, 90th and 97th) for each completed week from 18-40 weeks of gestation were derived from smoothed centile curves. The median GWG across pregnancy during specific antenatal visits was 1.29 at 18, 4.44 at 26, 5.8 at 30 and 9.06 kg at 40 weeks of gestation. Nearly 26% of participants had GWG < 10th centile at 18-20 weeks as per INTERGROWTH-21st reference and this increased to 45% at delivery. Significant predictors of GWG included maternal age, height, first trimester body mass index, parity, type of family, and use of clean fuel for cooking.

CONCLUSION

These GWG percentiles will serve as a useful reference, particularly during the WHO recommended antenatal visit schedule for optimum pregnancy outcomes, for clinicians and researchers. Multiple independent biological and social predictors of GWG suggest that single interventions are unlikely to bridge the gap between general Indian population and international references.

Screening and management options for severe thinness during pregnancy in India

This paper answers research questions on screening and management of severe thinness in pregnancy, approaches that may potentially work in India, and what more is needed for implementing these approaches at scale. A desk review of studies in the last decade in South Asian countries was carried out collating evidence on six sets of strategies like balanced energy supplementation (BEP) alone and in combination with other interventions like nutrition education. Policies and guidelines from South Asian countries were reviewed to understand the approaches being used. A 10-point grid covering public health dimensions covered by World Health Organization and others was created for discussion with policymakers and implementers, and review of government documents sourced from Ministry of Health and Family Welfare. Eighteen studies were shortlisted covering Bangladesh, India, Nepal, and Pakistan. BEP for longer duration, preconception initiation of supplementation, and better pre-supplementation body mass index (BMI) positively influenced birthweight. Multiple micronutrient supplementation was more effective in improving gestational weight gain among women with better pre-supplementation BMI. Behavior change communication and nutrition education showed positive outcomes on dietary practices like higher dietary diversity. Among South Asian countries, Sri Lanka and Nepal are the only two countries to have management of maternal thinness in their country guidelines. India has at least nine variations of supplementary foods and three variations of full meals for pregnant women, which can be modified to meet additional nutritional needs of those severely thin. Under the National Nutrition Mission, almost all of the globally recommended maternal nutrition interventions are covered, but the challenge of reaching, identifying, and managing cases of maternal severe thinness persists. This paper provides four actions for addressing maternal severe thinness through available public health programs, infrastructure, and human resources.

Early pregnancy body mass index, gestational weight gain and perinatal outcome in an obstetric population in Lagos, Nigeria

Introduction

the burden of overweight and obesity is rapidly increasing worldwide with significant health and social consequences. We determined the prevalence of overweight and obesity, pattern of gestational weight gain (GWG) and the associations of these with perinatal outcome among pregnant women in Lagos, Nigeria.

Methods

this was a retrospective review of case records of all deliveries in Lagos State University Teaching Hospital (LASUTH) over a period of two years. Case records of women with singleton pregnancies who registered for antenatal care at or below 20 weeks gestation were retrieved and reviewed to extract information on demography, anthropometrics, composites of pregnancy and perinatal outcomes. World Health Organization classification of BMI and the United States Institute of Medicine categorization of GWG were used to stratify subjects.

Results

out of 4,512 deliveries, 365 (8.1%) met our criteria. The prevalence of overweight and obesity in early pregnancy was 34.6% and 25.6% respectively while 2.9% were underweight. Thirty-seven (11.1%) pregnant women gained more than the recommended weight while 77.8% of underweight pregnant women gained less than the recommended weight. Following multiple logistic regression analysis, obesity in early pregnancy was significantly related to hypertensive pregnancy disorder (AOR 2.2; 95% CI, 1.08-4.32, p = 0.030), gestational diabetes mellitus (AOR 14.4; 95% CI, 4.85-42.6, p = < 0.001), caesarean section (AOR 2.7; 95% CI, 1.51-4.87, p = 0.001) and infections (AOR 4.9; 95% CI, 1.93-12.62, p = 0.001) while excessive GWG was significantly associated with gestational diabetes mellitus (AOR 4.8; 95% CI, 1.63-14.12, p = 0.004).

Conclusion

prevalence of early pregnancy overweight, obesity and excessive GWG were high among pregnant women in Nigeria and were associated with significant adverse consequences.

Macrosomia and large for gestational age in Asia: One size does not fit all

Macrosomia, usually defined as infant birth weight of ≥4000 g, does not consider gestational age, sex, or country/region-specific differences in mean birth weight and maternal body weight. This issue is particularly relevant for Asia, where 60% of the world's population lives, due to variations in maternal size and birth weights across populations. Large for gestational age (LGA), defined as birth weight > 90th centile, is a more sensitive measure as it considers gestational age and sex, though it is dependent on the choice of growth charts. We aimed to review reporting of macrosomia and LGA in Asia. We reviewed the literature on prevalence and risk of macrosomia and LGA in Asia over the last 29 years. Prevalence of macrosomia ranged from 0.5% (India) to 13.9% (China) while prevalence of LGA ranged from 4.3% (Korea) to 22.1% (China), indicating substantial variation in prevalence within and between Asian countries. High pre-pregnancy body mass index, excessive gestational weight gain, and impaired glucose tolerance conferred risk of macrosomia/LGA. Incidence of macrosomia and LGA varies substantially within and between Asian countries, as do the growth charts and definitions. The latter makes it impossible to make comparisons but suggests differences in intrauterine growth between populations. Reporting LGA, using standardized country/regional growth charts, would better capture the incidence of high birth weight and allow for comparison and identification of contributing factors. Better understanding of local drivers of excessive intrauterine growth could enable development of improved strategies for prevention and management of LGA.

Association between Maternal Dietary Diversity and Low Birth Weight in Central India: A Case-Control Study

Low birth weight (LBW) is one of the major public health challenges in India. LBW etiology is multifactorial and linked to multiple determinants, including maternal undernutrition and sociodemographic characteristics. The objective of the present endeavor was to assess how maternal dietary diversity and other sociodemographic factors among marginalized populations are associated with the incidence of LBW. The study was a part of the community-based intervention that aimed to improve maternal and child health in the Morena district of Madhya Pradesh, a state in central India. In this case-control study, cases were defined as mothers with an LBW child (<2500 grams) and controls as mothers without an LBW child. A quantitative survey was done with women of reproductive age, having at least one child aged 0–24 months. We calculated the dietary diversity based on the number of food groups consumed during pregnancy by women on a daily basis. Stepwise logistic regression models were built to test for associations between sociodemographic and dietary diversity variables and LBW incidence. There were 157 mothers with and 214 without an LBW child. Women's diets mainly consisted of grains, such as wheat, rice, maize, and roots and tubers. Eggs and meat were consumed by less than 1% of the women. There were 20% lesser chances of an LBW child with increasing maternal dietary diversity scores (odds ratio: 0.79; 95% CI: 0.65, 0.96). The poor maternal diet quality during pregnancy may result in adverse birth outcomes with long-term consequences in a child.

Gestational weight gain in sub-Saharan Africa: Estimation based on pseudo-cohort design

Background

Inadequate or excess gestational weight gain (GWG) leads to multiple undesirable birth outcomes. Yet, in sub-Saharan Africa (SSA) little is known about the weight gain pattern in pregnancy. The purpose of the study is to estimate the average gestational weight gain (GWG) in sub-Saharan Africa (SSA) and to examined whether there had been recent improvements or not.

Methods

Based on cross-sectional anthropometric data extracted from multiple Demographic and Health Surveys conducted in SSA, we estimated the average GWG in the region. Pseudo-cohort design was used to reconstruct GWG trajectories based on aggregated data of 110,482 women extracted from 30 recent surveys. Trend in GWG between 2000 and 2015 was determined using the data of 11 SSA countries. Pre-pregnancy weight was estimated based on the weight of non-pregnant women at risk of conception.

Results

On average, women in SSA gain inadequate weight (6.6 kg, 95% confidence interval, 6.0–7.2) over pregnancy. No meaningful gain was observed in the first trimester; whereas, women in the second and third trimesters put on 2.2 and 3.2 kg, respectively. The highest weight gain (10.5, 8.2–12.9 kg) was observed in Southern African sub-region and the lowest in Western Africa (5.8, 5.0–6.6 kg). The GWG among women who had secondary or above education (9.5, 8.2–10.9 kg) was higher than women with lower education (5.0, 4.3–5.8 kg). Likewise, GWG in women from richest households (9.0, 7.2–10.7 kg) was superior to those from poorest households (6.1, 5.3–7.0 kg). The estimated recent (2015–20) mean GWG (6.6, 5.8–7.4 kg) was not significantly different from what had been at beginning of the new millennium (6.7, 5.9–7.5 kg).

Conclusion

In SSA GWG is extremely low and is not showing improvements.

Prevalence and factors associated with triple burden of malnutrition among mother-child pairs in India: a study based on National Family Health Survey 2015-16

BACKGROUND

Malnutrition in mothers as well as in children is a significant public health challenge in most of the developing countries. The triple burden of malnutrition is a relatively new issue on the horizon of health debate and is less explored among scholars widely. The present study examines the prevalence of the triple burden of malnutrition (TBM) and explored various factors associated with the TBM among mother-child pairs in India.

METHODS

Data used in this study were drawn from the fourth round of the National Family Health Survey (NFHS-IV) conducted in 2015-16 (N = 168,784). Bivariate and binary logistic regression analysis was used to quantify the results. About 5.7% of mother-child pairs were suffering from TBM.

RESULTS

Age of mother, educational status of the mother, cesarean section delivery, birth size of baby, wealth status of a household, and place of residence were the most important correlates for the triple burden of malnutrition among mother-child pairs in India. Further, it was noted that mothers with secondary education level (AOR: 1.15, CI 1.08-1.23) were having a higher probability of suffering from TBM, and interestingly the probability shattered down for mothers having a higher educational level (AOR: 0.90, CI 0.84-0.95). Additionally, mother-child pairs from rich wealth status (AOR: 1.93, CI 1.8-2.07) had a higher probability of suffering from TBM.

CONCLUSION

From the policy perspective, it is important to promote public health programs to create awareness about the harmful effects of sedentary lifestyles. At the same time, this study recommends an effective implementation of nutrition programs targeting undernutrition and anemia among children and obesity among women.

Association of gestational weight gain with cesarean section: a prospective birth cohort study in Southwest China

Background

Cesarean section (CS) is a rising public health issue globally, and is particularly serious in China. Numerous studies have suggested that gestational weight gain (GWG) control may be an effective way to reduce the rate of CS. However, rare study has examined the association between GWG and CS among women in Southwest China. We proposed to examine their association based on a prospective birth cohort, and further to explore the optimal GWG range.

Methods

We retrieved data from a prospective birth cohort from Sichuan Provincial Hospital for Women and Children, Southwest China. Unconditional multivariable logistic regression was used to examine the association between GWG and CS by adjusting for potential confounders. In one analysis, we incorporated the GWG as a categorical variable according to the Institute of Medicine (IOM) recommendation, similar to the method used in the majority of previous studies. In the other analysis, we directly incorporated GWG as a continuous variable and natural cubic splines were used to characterize the potential nonlinear exposure-response relationship, aiming to identify the optimal GWG. We further stratified the above analysis by pre-pregnancy BMI and GDM, and then a heterogeneity test based on a multivariate meta-analysis was conducted to examine whether the stratum specific estimations agreed with each other.

Results

A total of 1363 participants were included. By adopting the IOM recommendation, the adjusted OR of CS was 0.63 (0.47, 0.84) for insufficient GWG and 1.42 (1.06, 1.88) for excessive GWG. After stratification by pre-pregnancy BMI, we found a higher risk of CS in associated with excessive GWG in the stratum of underweight compared with the other strata, which implied that pre-pregnancy BMI may be an effect modifier. By applying a flexible spline regression, the optimal GWG levels in terms of reducing the CS rate based on our data were more stringent than those of IOM recommendation, which were 9–12 kg for underweight women, < 19 kg for normal weight women and < 10 kg for overweight/obese women.

Conclusions

These results suggested that a more stringent recommendation should be applied in Southwest China, and that more attention should be given to underweight women.

Population estimates, consequences, and risk factors of obesity among pregnant and postpartum women in India: Results from a national survey and policy recommendations

OBJECTIVE

To examine prevalence, risk factors, and consequences of maternal obesity; and provide evidence on current policies and programs to manage maternal obesity in India.

METHODS

This is a mixed-methods study. We analyzed the National Family Health Survey (NFHS)-4 data (2015-16) to estimate the prevalence and risk factors of obesity, followed by a desk review of literature and stakeholder mapping with interviews to develop policy guidance.

RESULTS

National prevalence of obesity (defined by WHO as body mass index ≥25) was comparable among pregnant (12%) and postpartum women (13%) ≥20 years of age. A high prevalence of obesity (>40%) was observed in over 30 districts in multiple states. Older maternal age, urban residence, increasing wealth quintile, and secondary education were associated with increased odds of obesity among pregnant and postpartum women; higher education increased odds among postpartum women only (OR 1.90; 95% CI, 1.44-2.52). Dietary variables were not associated with obesity. Several implementation challenges across healthcare system blocks were observed at policy level.

CONCLUSION

Overall prevalence of obesity in India during and after pregnancy is high, with huge variation across districts. Policy and programs must be state-specific focusing on prevention, screening, and management of obesity among pregnant and postpartum women.

Nausea, vomiting and poor appetite during pregnancy and adverse birth outcomes in rural Nepal: an observational cohort study

Background

Nausea and vomiting are experienced by a majority of pregnant women worldwide. Previous studies have yielded conflicting results regarding their impact on birth outcomes and few studies have examined this relationship in settings with limited resources. We aimed to determine the effect of nausea, vomiting and poor appetite during pregnancy on birth outcomes in rural Nepal.

Methods

Observational cohort study using data collected in two randomized, community-based trials to assess the effect of influenza immunization during pregnancy on reproductive and respiratory outcomes among pregnant women and their offspring. Pregnant women in Sarlahi District, Nepal were recruited from 2011 to 2013. Exposure was defined as nausea, vomiting or poor appetite at any point during pregnancy and by trimester; symptoms were recorded monthly throughout pregnancy. Adverse outcomes were low birth weight (LBW), preterm birth and small for gestational age (SGA). Adjusted relative risks (aRR) with 95% CIs are reported from Poisson regressions with robust variance.

Results

Among 3,623 pregnant women, the cumulative incidence of nausea, vomiting or poor appetite was 49.5% (n = 1793) throughout pregnancy and 60.6% (n = 731) in the first trimester. Significantly higher aRRs of LBW and SGA were observed among women experiencing symptoms during pregnancy as compared to symptom free women (LBW: aRR 1.20; 95% CI 1.05 1.28; SGA: aRR 1.16; 95% CI 1.05 1.28). Symptoms in the first trimester were not significantly associated with any of the outcomes. In the second trimester, we observed significantly higher aRRs for LBW and SGA (LBW: aRR 1.17; 95% CI 1.01 1.36; SGA: aRR 1.16; 95% CI 1.05 1.29) and a significantly lower aRR for preterm birth (aRR 0.75; 95% CI 0.59 0.96). In the third trimester, we observed significantly higher aRRs for LBW and SGA (LBW: aRR 1.20; 95% CI 1.01 1.43; SGA: aRR 1.14; 95% CI 1.01 1.29).

Conclusions

Symptoms of nausea, vomiting or poor appetite during pregnancy are associated with LBW, SGA and preterm birth in a setting with limited resources, especially beyond the first trimester.

Trial registration

Education and prevalence of overweight and obesity among reproductive age group women in Ethiopia: analysis of the 2016 Ethiopian demographic and health survey data

Background

Globally, the prevalence of overweight and obesity is escalating, particularly among women and wealthier people. In many developed countries, overweight and obesity are more prevalent in persons with lower socioeconomic status. In contrast, studies in developing countries have reported a higher prevalence rate of overweight and obesity among women with higher educational status. Hence, this study aimed to assess the association between education and the prevalence of overweight and obesity among reproductive age group women in Ethiopia.

Methods

This cross-sectional study was done based on the 2016 Ethiopian demographic and health survey (EDHS) data. From the total 15,683 women participants of the 2016 EDHS, 2848 reproductive age group women aged 15–49 years old who had a complete response to all variables of interest were selected and retained for analysis. Data were analyzed using SPSS version 20 software program. Both descriptive and logistic regression models were used for analysis.

Results

The prevalence of overweight and obesity among the study participants was 11.5 and 3.4% respectively. The combined prevalence of overweight and obesity was 14.9%. From the total participants who are overweight and, or obese, majority, 83.3% were urban dwellers and the remaining 16.7% were rural dwellers. Education was positively associated with overweight and obesity among women. Besides, increased age, region, living in urban areas, being in rich quintile, increased frequency of watching television, and frequency of using internet were significantly associated with the odds of being overweight and obese among reproductive age group women in Ethiopia.

Conclusions

The prevalence of overweight and obesity among reproductive age group women in Ethiopia is increasing compared to previous studies. Education was found to be a risk factor for overweight and obesity among women. Hence, context based interventions on the prevention and control methods of overweight and obesity are required.

Effect of Behavioural Interventions for Obesity Prevention in Pregnancy on the Adequacy of Gestational Weight Gain and Retention: Metabolic Health of Indian Women

The aim of this study was to measure the adequacy of gestational weight gain (GWG) in Indian women using various behavioural interventions during pregnancy, which primarily aim to observe the effects on obesity markers and weight retention.

In this experimental study, one hundred and forty pregnant women underwent interventions in 5 groups, control (C), diet (D), home exercise (HE), supervised exercise (SE) and supervised exercise with diet (SED), from pregnancy through delivery with 2 months follow-up post-delivery. The outcome measures were GWG and baby birth weight.

A one-way ANOVA indicated no differences in the mean GWG between groups (12.39±4.71 kg, p=0.947). The control group had the most (50%) and both the supervised exercise groups had the fewest (32%) women who gained above the recommended GWG, followed by the diet group (33.3%). The D and HE groups had the most women who gained within the GWG range, while both the SE and SED groups had the most women who gained below the GWG range. However, these results did not affect the birth weight between the groups (mean 2.96 kg±0.40, p=0.203). In women with normal BMIs, (18.5-22.9 kg/m2), the diet group had the most effective maintenance of adequate GWG, with 15%, 55%, and 30% of the women gaining above, within, and below the recommended GWG, respectively. The SE and SED groups had the least postpartum weight retention (PPWR) at 2 months, followed by the HM, D and C groups; i.e., the results showed a trend in the desired direction clinically, although they were not statistically significant (p=0.12).

Supervised exercise can be effectively used as a pregnancy intervention to prevent excess GWG in Indian women. Diet counselling was found to be the next best intervention in combination with exercise, as well as for women with normal BMI.

Pharmacokinetics of HIV therapies in pregnant patients: an update

INTRODUCTION

Mother-to-child transmission (MTCT) of HIV is thought to account for over 90% of new pediatric infections, and is associated with poor maternal and fetal outcomes. As such ensuring further reduction in MTCT is a priority in HIV treatment and prevention programs.

AREAS COVERED

This review aims to provide a comprehensive update on the pharmacokinetics of recently approved antiretroviral drugs and novel drug formulations and delivery systems. Alongside recent recommendations for dose adjustments, and an overview of the implications of co-infections on the pharmacokinetics of antiretrovirals relevant to pregnant HIV positive patients. Additionally, potential opportunities to progress pharmacokinetic research of new treatments in this population are highlighted.

EXPERT OPINION

In order to improve our understanding of how to provide safe and effective treatment to HIV positive pregnant women, further work is required to enable their inclusion in early stages of clinical trials. Incentives must be created for this research, in the form of additional investment by key stakeholders and regulatory agencies. Furthermore, as the incidence of MTCT is reduced globally there is a need to conduct long-term pharmacovigilance studies in uninfected children exposed to HIV and antiretrovirals in utero, in order to determine the safest and most effective antiretroviral therapies.

The differences in the consumption of proteins, fats and carbohydrates in the diet of pregnant women diagnosed with arterial hypertension or arterial hypertension and hypothyroidism

Background

Excessive body weight induces the occurrence of arterial hypertension. The risk associated with irregularities during the perinatal period is increased in women with diagnosed hypothyroidism. Disorders of thyroid functions during pregnancy may cause higher body weight gains. The aim of this project was to determine the differences in the average daily intake of proteins, fats and carbohydrates in women with arterial hypertension and with hypothyroidism.

Methods

The control group (Group I) included healthy women. In this group, no complications during the course of pregnancy were observed and the delivery was on the due date. Group II was comprised of patients with arterial hypertension. Group III included patients with arterial hypertension, who were diagnosed with hypothyroidism before pregnancy. The women’s eating habits and dietary composition were analyzed based on a dietary assessment.

Results

Women with arterial hypertension (Group II) consumed the highest number of calories per day, while women with a normal pregnancy consumed the lowest amount of calories. The daily consumption of vegetable protein was similar in all study groups. The average daily consumption of fat, cholesterol and carbohydrates was the highest among women with diagnosed arterial hypertension. Women with arterial hypertension and hypothyroidism more frequently gave birth before the 38th week of pregnancy. The average daily intake of Arginine, Lysine, Methionine and Tryptophan was lower in the group of women with a normal pregnancy than in the two other groups.

Conclusions

Excessive calorie intake causing significant body weight gain fostered the occurrence of arterial hypertension during pregnancy.

Prevalence and factors associated with underweight, overweight and obesity among women of reproductive age in India

INTRODUCTION

Although the prevalence of underweight is declining among Indian women, the prevalence of overweight/obesity is increasing. This study examined the prevalence and factors associated with underweight and overweight/obesity among reproductive-aged (i.e., 15-49 years) women in India.

METHODS

This cross-sectional study analyzed data from the 2015-16 National Family Health Survey. The Asian and World Health Organization (WHO) recommended cutoffs for body mass index (BMI) were used to categorize body weight. The Asian and WHO BMI cutoffs for combined overweight/obesity were ≥ 23 and ≥ 25 kg/m2, respectively. Both recommendations had the same cutoff for underweight, < 18.5 kg/m2. After prevalence estimation, logistic regression was applied to investigate associated factors.

RESULTS

Among 647,168 women, the median age and BMI was 30 years and 21.0 kg/m2, respectively. Based on the Asian cutoffs, the overall prevalence of underweight was 22.9%, overweight was 22.6%, and obesity was 10.7%, compared to 15.5% overweight and 5.1% obesity as per WHO cutoffs. The prevalence and odds of underweight were higher among young, nulliparous, contraceptive non-user, never-married, Hindu, backward castes, less educated, less wealthy, and rural women. According to both cutoffs, women who were older, ever-pregnant, ever-married, Muslims, castes other than backwards, highly educated, wealthy, and living in urban regions had higher prevalence and odds of overweight/obesity.

CONCLUSION

The prevalence of both non-normal weight categories (i.e., underweight and overweight/obesity) was high. A large proportion of women are possibly at higher risks of cardiovascular and reproductive adverse events due to these double nutrition burdens. Implementing large-scale interventions based on these results is essential to address these issues.

Impact of exercise on maternal gestational weight gain: An updated meta-analysis of randomized controlled trials

BACKGROUND

Clinical evidence indicates that women will benefit from regular physical activity during pregnancy. This study aimed to summarize and update the evidence on the effect of exercise on maternal gestational weight gain (GWG).

METHODS

We conducted a systematic literature search of Pubmed, Embase, and Cochrane Library from inception until July, 2018 for randomized controlled trials (RCTs) that investigate the effect of physical exercises on the maternal GWG compared with that of no physical exercises or conventional medical care. We extracted data from eligible trials for study characteristics, interventions, patients' baseline characteristics and outcomes for the study populations of interest. We conducted meta-analyses using random effects models.

RESULTS

From 844 citations, 23 RCTs including 4462 pregnant women met the inclusion criteria. Meta-analysis indicated that compared with that in women having conventional medical care, GWG was significantly decreased in pregnant women with physical exercise [weighted mean difference (WMD) -1.02, 95% CI -1.35 to -0.70; P < .01; I = 48.4%]. Women appeared to benefit more for gestational weight control for exercise frequency of 3 times per week (WMD -1.22, 95% CI -1.55 to -0.90; I = 40.3%) and exercise duration of 30 to 45 minutes each time (WMD -1.32, 95% CI -1.79 to -0.85; I = 1.5%).

CONCLUSION

This meta-analysis provides indications that exercise intervention can reduce maternal GWG for pregnant women, especially for those with exercise frequency of 3 times per week and duration of 30 to 45 minutes each time.

Gestational Weight Gain among Healthy Pregnant Women from Asia in Comparison with Institute of Medicine (IOM) Guidelines-2009: A Systematic Review

In 1990, Institute of Medicine (IOM) recommended gestational weight gain (GWG) ranges for women in the United States primarily to improve infant birth weight. Changes in key aspects of reproductive health of women of child bearing age, a rising prevalence of obesity, and noncommunicable diseases prompted the revision of IOM guidelines in 2009. However, there is no such recommendation available for Asian women. This systematic review assesses the utility of IOM-2009 guidelines among Indian and other Asian pregnant women in terms of maternal and fetal outcomes. 624 citations were identified using PubMed and Google Scholar, out of which 13 were included. Prospective/retrospective studies of healthy Asian women with a singleton pregnancy which specifically examined fetal-maternal outcomes relative to IOM-2009 guidelines were included. Results. Majority of pregnant Indian women achieved less GWG than the recommendations whereas a mixed trend was noticed among the other Asian pregnant women. The most common fetal-maternal complications among the excessive GWG women were found to be macrosomia, large for gestational age and caesarean section followed by gestational diabetes and hypertension, whereas low birth weight, small for gestational age and preterm birth, was found to be associated with low GWG women. The findings highlight the need for appropriate GWG limits across the different body mass index levels specifically for Indians and other Asian population. However, there are not enough publications regarding the utility of IOM-2009 guidelines among the Indian and other Asian women. Thus, higher-quality researches are warranted in future to further validate the findings of the present review.

Insights on Medical Nutrition Therapy for Type 2 Diabetes Mellitus: An Indian Perspective

It is critical to integrate medical nutrition therapy (MNT) provided by a registered dietician (RD) into primary care of type 2 diabetes mellitus (T2DM). This is necessary to achieve the goals of improving overall metabolic measures beyond calorie restriction and weight loss. Misconceptions about nutrition in T2DM add to the challenges of executing MNT in a culturally sensitive population. The current review provides insights into MNT for the prevention and management of T2DM in India, based on both evidence and experience. It revisits historical Indian studies and provides information on appropriate dietary intake of carbohydrates (60-70%), proteins (~ 20%) and fats (10%) that will be acceptable and beneficial in an Indian T2DM population. It discusses nuances of types of carbohydrates and fats and explains associations of increased dietary fiber intake, balanced intake of low and high glycemic index foods and substitution of saturated fats with plant-based polyunsaturated fats in improving outcomes of T2DM and attenuating risk factors. The article also deliberates upon special patient populations with comorbid conditions and diseases and the necessary adjustments needed in their nutritional care. It outlines a step-wise approach to MNT involving a careful interplay of nutrition assessment, diagnosis, individualization and patient counseling. Overall, the success of MNT relies on providing accurate, acceptable and appropriate dietary choices for continued patient adherence. Collaborative efforts from diabetologists, endocrinologists, internists and RDs are required to prioritize and implement MNT in diabetes practice in India.Funding: Signutra Inc.

Prenatal arsenic exposure, child marriage, and pregnancy weight gain: Associations with preterm birth in Bangladesh

BACKGROUND

Preterm birth is a disease of multifactorial etiologies that has environmental, social, and maternal health components. Individual studies have shown that exposure to arsenic contaminated drinking water, child marriage, and low maternal weight gain during pregnancy contribute to preterm birth. These factors are highly prevalent and often co-exist in Bangladesh, a country in South Asia with one of the world's highest prevalences of preterm birth.

OBJECTIVE

To evaluate the individual and interactive effects of prenatal arsenic exposure, child marriage, and pregnancy weight gain on preterm birth in a prospective birth cohort in Bangladesh.

METHODS

During 2008-2011, we recruited 1613 pregnant women aged ≥18years at ≤16weeks of gestation and followed them until 1-month post-partum. We measured total arsenic in drinking water (n=1184) and in maternal toenails (n=1115) collected at enrollment and ≤1-month post-partum, respectively using inductively coupled plasma mass spectrometry. Child marriage (<18years old) was defined using self-report, and 2nd and 3rd trimester pregnancy weight gain was calculated using monthly records. Gestational age was determined at enrollment by ultrasound.

RESULTS

In multivariate adjusted Poisson regression models, the risk ratios (RR) for preterm birth were 1.12 (95% CI: 1.07-1.18) for a unit change in natural log water arsenic exposure, 2.28 (95% CI: 1.76-2.95) for child marriage, and 0.64 (95% CI: 0.42-0.97) for a pound per week increase in maternal weight during the 2nd and 3rd trimesters. In stratified analysis by child marriage, pregnancy weight gain was inversely associated with preterm birth among women with a history of child marriage (RR=0.58; 95% CI: 0.37-0.92), but not among women with no history of child marriage (RR=86; 95% CI: 0.37-2.01). Mediation analysis revealed that both arsenic exposure and child marriage had small but significant associations with preterm birth via lowering pregnancy weight gain. Similar associations were observed when arsenic exposure was assessed using maternal toenail arsenic concentrations.

CONCLUSIONS

Reducing arsenic exposure and ending child marriage could reduce the risk of preterm birth in Bangladesh. Furthermore, enhancing nutritional support to ensure adequate weight gain during pregnancy may provide additional benefits especially for women with a history of child marriage.
