Post-partum weight retention in women in Asia: a systematic review

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.

Obesity in South and Southeast Asia-A new consensus on care and management

Obesity is a chronic disease in which the abnormal or excessive accumulation of body fat leads to impaired health and increased risk of mortality and chronic health complications. Prevalence of obesity is rising rapidly in South and Southeast Asia, with potentially serious consequences for local economies, healthcare systems, and quality of life. Our group of obesity specialists from Bangladesh, Brunei Darussalam, India, Indonesia, Malaysia, Philippines, Singapore, Sri Lanka, Thailand, and Viet Nam undertook to develop consensus recommendations for management and care of adults and children with obesity in South and Southeast Asia. To this end, we identified and researched 12 clinical questions related to obesity. These questions address the optimal approaches for identifying and staging obesity, treatment (lifestyle, behavioral, pharmacologic, and surgical options) and maintenance of reduced weight, as well as issues related to weight stigma and patient engagement in the clinical setting. We achieved consensus on 42 clinical recommendations that address these questions. An algorithm describing obesity care is presented, keyed to the various consensus recommendations.

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.

Simulation of 3D Body Shapes for Pregnant and Postpartum Women

Several studies have reported that pre-pregnant women’s body mass index (BMI) affects women’s weight gain with complications during pregnancy and the postpartum weight retention. It is important to control the BMI before, during and after pregnancy. Our objectives are to develop a technique that can compute and visualize 3D body shapes of women during pregnancy and postpartum in various gestational ages, BMI, and postpartum durations. Body changes data from 98 pregnant and 83 postpartum women were collected, tracked for six months, and analyzed to create 3D model shapes. This study allows users to simulate their 3D body shapes in real-time and online, based on weight, height, and gestational age, using multiple linear regression and morphing techniques. To evaluate the results, precision tests were performed on simulated 3D pregnant and postpartum women’s shapes. Additionally, a satisfaction test on the application was conducted on new 149 mothers. The accuracy of the simulation was tested on 75 pregnant and 74 postpartum volunteers in terms of relationships between statistical calculation, simulated 3D models and actual tape measurement of chest, waist, hip, and inseam. Our results can predict accurately the body proportions of pregnant and postpartum women.

Longitudinal Associations of Marital, Parenting, and Employment Transitions with Weight Gain in a Multi-Ethnic Asian Population Aged 21 Years and Above

Identifying when most weight gain occurs throughout the life course can inform targeted public health interventions. We evaluated the association of childbirth, marriage, and employment changes with weight changes in a multi-ethnic Asian cohort. Singapore Multi-Ethnic Cohort participants ≥21 years (n = 9655) who identified as ethnic Chinese, Malay, or Indian were weighed and interviewed about marital status, employment, and number of children at baseline and after about four years. We used multivariable regression to evaluate life transitions in relation to weight change and major gain (≥5 kg), and adjusted for socio-demographic covariates. Weight gain was 3.55 kg (95% CI 3.17, 3.94) higher in young adults (21-30 years) compared with participants older than 60 years at baseline. Getting married was associated with weight gain in women, but not men (p interaction < 0.01). Women who got married gained 1.63 kg (95% CI 0.88, 2.38) more weight and were more likely to gain ≥5 kg (OR 1.99, 95% CI 1.35, 2.93) than those remaining unmarried. Having children was not associated with weight gain. Only among ethnic Indians, remaining a homemaker was associated with less weight gain than remaining employed. In this multi-ethnic Asian population, obesity prevention efforts should target young adulthood and, in women, the transition into marriage.

Postpartum Weight Retention and Its Determinants in Lebanon and Qatar: Results of the Mother and Infant Nutrition Assessment (MINA) Cohort

Excessive Postpartum Weight Retention (PWR) is postulated to increase the risk of adverse health outcomes for mothers and offspring. Using data from the Mother and Infant Nutritional Assessment (MINA) cohort in Lebanon and Qatar, this study aimed to examine PWR and its determinants at 6 months after delivery. Pregnant women (n = 183) were recruited during their first trimester and were followed up through pregnancy and after delivery. During this period, face-to-face interviews as well as extraction from medical charts were conducted to collect data regarding the socioeconomic, anthropometric and dietary intake of participants. The mean PWR (kg) among participants was 3.1 ± 5.6 at delivery, and 3.3 ± 5.3 and 2.7 ± 4.7 at 4 and 6 months after delivery, respectively. Results of the multiple logistic regression analyses showed that a Qatari nationality and excessive GWG were associated with higher odds of a high PWR (above median) while an insufficient GWG had lower odds. After adjustment for energy, participants with a high PWR reported a greater intake of proteins, Trans fat, cholesterol, sodium and lower intakes of mono and polyunsaturated fat as compared to those with a low PWR (below median). These findings suggested priority areas for interventions to prevent excessive PWR amongst women of childbearing age in Lebanon and Qatar.

Secular trends in postpartum weight retention from 2003 to 2012: a nationwide, population-based, retrospective, longitudinal study in South Korea

OBJECTIVE

To assess the secular trends in postpartum weight retention (PWR) over a decade with the population-based risk factors.

DESIGN

Retrospective cohort study.

SETTING

A national health screening examination data provided by the National Health Insurance Service in South Korea.

PARTICIPANTS

130 551 women who delivered babies between 1 January 2003 and 31 December 2012 and who underwent a national health screening examination 1 to 2 years prior to delivery and within 1 year after delivery.

METHODS

Their PWR were determined during the study period of 2003-2012. We fitted logistic regression and linear mixed models to assess the independent contribution of PWR to obesity after adjusting for potential confounders.

PRIMARY AND SECONDARY OUTCOME MEASURES

Prepregnancy and postpartum weight and body mass index (BMI).

RESULTS

The adjusted PWR increased from mean value of 2.02 kg in 2003 (95% CI 1.88 to 2.15) to 2.79 kg in 2012 (95% CI 2.73 to 2.84) (p value for trend <0.01), after adjusting potential confounders including age, prepregnancy time, postpartum time, prepregnancy BMI, income and smoking status. The risk for a PWR of more than 5 kg also increased over the study period.

CONCLUSIONS

Secular increases in PWR have been significantly observed between 2003 and 2012 for childbearing women. It is necessary to identify risk factors contributing to the observed increase and develop effective strategies to address the heightened risk for PWR.

Predictors and consequences of weight retention in the early and late postpartum period in women with gestational diabetes

AIMS

To assist preventive strategies, we investigated the predictors and consequences of postpartum weight retention (PPWR) in the early and late postpartum period in women with gestational diabetes (GDM).

METHODS

862 women with GDM between 2011 and 2019 were prospectively included. We investigated PPWR at 6-8 weeks (n = 862) and at 1-year (n = 259) postpartum. Potential predictors included gestational weight gain (GWG), weight, BMI, and glucose control parameters during and after pregnancy.

RESULTS

Mean PPWR at 6-8 weeks and 1-year postpartum were 4.6 ± 5.7 kg and 4.0 ± 7.4 kg. The proportion of women with PPWR at 6-8 weeks and at 1-year postpartum were 81% and 66.4% respectively. At 6-8 weeks postpartum, women with PPWR had higher pre-pregnancy weight, 7.5 ± 0.2 kg higher GWG and higher postpartum weight (all p ≤ 0.02), without presenting metabolic differences. At 1-year postpartum, there were no differences in anthropometric parameters before and during pregnancy between women with or without PPWR, except for a 4 ± 0.4 kg higher GWG (p < 0.001). However, women with PPWR had increased postpartum weight and BMI, higher fasting glucose and more pronounced increase in Δfasting glucose and ΔHbA1c at 1-year postpartum (all p ≤ 0.03). GWG predicted higher PPWR at both 6-8 weeks and at 1-year postpartum (all p < 0.001).

CONCLUSION

Women with PPWR had increased anthropometric parameters and adverse metabolic consequences at 1-year postpartum. GWG was the most relevant predictor of PPWR.

Dose-Response Relationships between Breastfeeding and Postpartum Weight Retention Differ by Pre-Pregnancy Body-Mass Index in Taiwanese Women

Postpartum weight retention (PWR) is a risk factor for future obesity. The role of breastfeeding in reducing PWR is not fully understood. We examined the relationship between PWR and the duration of exclusive/partial breastfeeding in 52,367 postpartum women from 2012–2016 Taiwan national breastfeeding surveys. The women were interviewed at 7–14 months postpartum. Non-linear models were fit to examine the association between PWR and breastfeeding duration. PWR adjusted means and 95% confidence intervals were plotted and compared for the duration of exclusive/partial breastfeeding in the total sample and between pre-pregnancy body-mass index (BMI) groups (underweight, normal, overweight, and obese). Women who breastfed exclusively for >30 days showed significantly lower PWR than those who did not breastfeed and those who breastfed partially for the same duration, thereafter each additional duration of 30 days being associated with an average of 0.1–0.2 kg less PWR. Women who breastfed partially for 120 days showed lower PWR than those who did not or those who ceased to breastfeed, thereafter each additional duration of 30 days being associated with an average of 0.1 kg less PWR. Duration of breastfeeding needed to achieve significantly less PWR differed between pre-pregnancy BMI groups, but the effect of exclusive breastfeeding appeared earlier in the normal weight group. Women with obesity who breastfed exclusively for >30 or partially for >180 days, had lower PWR than non-obese groups. The observed dose–response relationship between breastfeeding duration and PWR supports the “every feeding matters” approach in breastfeeding promotion. The larger effect of exclusive and partial breastfeeding on PWR in women with obesity may draw special attention of breastfeeding promotion.

Postpartum Physical Activity and Weight Retention within One Year: A Prospective Cohort Study in Vietnam

After delivery, mothers are encouraged to increase physical activity (PA) gradually to regulate body weight; however, data on PA in relation to postpartum weight retention remains scarce, particularly among Asian women. In a cohort of 1617 Vietnamese mothers, we investigated the prospective association between habitual PA exposures at 3-month postpartum and weight retention at 6-month and 12-month postpartum. Detailed information on PA intensity and domains was collected from participants using a validated instrument specifically for Vietnamese women. Linear regression analyses and a general linear model for the repeated weight retention measures were used to ascertain the apparent relationships. On average, the participants reported 3.6 (SD 3.9) and 2.6 (SD 3.8) kg weight loss at 6- and 12-month postpartum, respectively. Total and light-intensity PA were inversely associated with the postpartum weight retention (p for trend <0.05). Our findings highlight the importance of resuming PA in the early postpartum period as an appropriate weight management strategy.

Patterns of Women's Postpartum Weight Retention and Its Associations with Maternal Obesity-Related Factors and Parity

Background: There is not much data on the effects of the timing of gestational weight gain (GWG), pre-pregnancy waist circumference (WC), pre-pregnancy body mass index (BMI), and parity, with postpartum weight retention (PPWR) trajectories. Methods: This study was based on a longitudinal cohort. Latent growth mixture models were applied to identify the latent trajectories of PPWR and test the effects of the predictors on distinct classes of PPWR trajectories. Results: Three PPWR trajectories were identified. About 2.8% (n = 26) of women were classified into Class 1, with an inverted U-shape trajectory; 6.6% (n = 61) were assigned to Class 2, with a rapid increase trajectory; 90.6% (n = 837) were classified into Class 3, with a significant decrease. Women who had a lower pre-pregnancy BMI (β = −0.279), higher pre-pregnancy WC (β = 0.111) and GWG (β = 0.723) were at a higher risk of retaining more weight at 1 month postpartum. Only GWG, especially GWG during late pregnancy, was associated with the rate of PPWR change. Parity was not associated with the changes in PPWR, while, compared to Class 1 trajectory, multiparous women were protected from having a Class 2 trajectory. Conclusions: Early targeted interventions should be taken to prevent women who were primiparous, and/or had a lower pre-pregnancy BMI and higher pre-pregnancy WC and GWG, from excessive PPWR.

An epidemiological evaluation of predictors of overweight and obesity in Garhwal region of Uttarakhand

Introduction

Now a day, obesity has become a chronic disorder affecting the larger population than any other disease in the world, which made its presence felt first in the Northern Hemisphere, and has now taken a pandemic look affecting practically almost all the countries of the globe.

Method

A cross sectional study with a sample size of 632 was carried out. Multistage stratified random sampling and “Kish” method was applied for selection of study area and selection of study subjects (21-60 years). WHO STEPS for NCD Risk Factor Surveillance, was used to gather the necessary data. Percentage, Chi square, & logistic regression analysis was done and significant level was taken at p < 0.05.

Results

As per Asia Pacific classification 16.0% & 33.4% of subjects while as per WHO classification 24.5% & 8.9% of subjects were found to be overweight and obese respectively. It was nearly 2 times higher in urban males. Central obesity was more commonly observed in urban subjects as compared to rural. At risk Waist hip ratio was recorded in 55.9% and high Weight height ratio was recorded in 66.8% of total subjects. All the predictors showed higher percentages in females of urban area and increased with the rise in age.

Conclusion

The present study reveals that, there is high prevalence of overweight and obesity in the study population. Certainly, there has been a considerable shift in their dietary and lifestyle profile. there appears to be an urgent need to develop suitable health strategies as well as intervention programmes for combating the prevalence of overweight and obesity.

Postpartum weight retention in relation to gestational weight gain and pre-pregnancy body mass index: A prospective cohort study in Vietnam

BACKGROUND

The prevalence of maternal overweight and obesity is increasing in Asia. This study prospectively investigated the association between pre-pregnancy body mass index (BMI), gestational weight gain (GWG) and 12-month postpartum weight retention (PPWR) in a large cohort of Vietnamese mothers.

METHODS

Of the 2030 pregnant women recruited from three cities in Vietnam at 24-28 weeks of gestation, a total of 1666 mothers were followed up for 12 months after delivery and available for analysis. The outcome variable PPWR was determined by subtracting the pre-pregnancy weight from the 12-month postpartum measured weight, while GWG and pre-pregnancy BMI were classified according to the Institute of Medicine and WHO criteria for adults, respectively. Linear regression models were used to ascertain the association between pre-pregnancy BMI, GWG and PPWR accounting for the effects of plausible confounding factors.

RESULTS

Both pre-pregnancy BMI and GWG were significantly associated with PPWR (P<0.001). The adjusted mean weight retention in underweight women before pregnancy (3.71kg, 95% confidence interval (CI) 3.37-4.05) was significantly higher than that in those with normal pre-pregnancy weight (2.34kg, 95% CI 2.13-2.54). Women with excessive GWG retained significantly more weight (5.07kg, 95% CI 4.63-5.50) on average at 12 months, when compared to mothers with adequate GWG (2.92kg, 95% CI 2.67-3.17).

CONCLUSIONS

Being underweight before pregnancy and excessive GWG contribute to greater weight retention twelve months after giving birth. Interventions to prevent postpartum maternal obesity should target at risk women at the first antenatal visit and control their weight gain during the course of pregnancy.

Gestational weight gain across continents and ethnicity: systematic review and meta-analysis of maternal and infant outcomes in more than one million women

BACKGROUND

The association between Institute of Medicine (IOM) guidelines and pregnancy outcomes across ethnicities is uncertain. We evaluated the associations of gestational weight gain (GWG) outside 2009 IOM guidelines, with maternal and infant outcomes across the USA, western Europe and east Asia, with subgroup analyses in Asia. The aim was to explore ethnic differences in maternal prepregnancy body mass index (BMI), GWG and health outcomes across these regions.

METHODS

Systematic review, meta-analysis and meta-regression of observational studies were used for the study. MEDLINE, MEDLINE In-Process, Embase and all Evidence-Based Medicine (EBM) Reviews were searched from 1999 to 2017. Studies were stratified by prepregnancy BMI category and total pregnancy GWG. Odds ratio (ORs) 95% confidence intervals (CI) applied recommended GWG within each BMI category as the reference. Primary outcomes were small for gestational age (SGA), preterm birth and large for gestational age (LGA). Secondary outcomes were macrosomia, caesarean section and gestational diabetes.

RESULTS

Overall, 5874 studies were identified and 23 were included (n = 1,309,136). Prepregnancy overweight/obesity in the USA, Europe and Asia was measured at 42%, 30% and 10% respectively, with underweight 5%, 3% and 17%. GWG below guidelines in the USA, Europe and Asia was 21%, 18% and 31%, and above was 51%, 51% and 37% respectively. Applying regional BMI categories in Asia showed GWG above guidelines (51%) was similar to that in the USA and Europe. GWG below guidelines was associated with a higher risk of SGA (USA/Europe [OR 1.51; CI 1.39, 1.63]; Asia [1.63; 1.45, 1.82]) and preterm birth (USA/Europe [1.35; 1.17, 1.56]; Asia [1.06; 0.78, 1.44]) than GWG within guidelines. GWG above guidelines was associated with a higher risk of LGA (USA/Europe [1.93; 1.81, 2.06]; Asia [1.68; 1.51 , 1.87]), macrosomia (USA/Europe [1.87; 1.70, 2.06]; Asia [2.18; 1.91, 2.49]) and caesarean (USA/Europe [1.26; 1.21, 1.33]; Asia [1.37; 1.30, 1.45]). Risks remained elevated when regional BMI categories were applied for GWG recommendations. More women in Asia were categorised as having GWG below guidelines using World Health Organization (WHO) (60%) compared to regional BMI categories (16%), yet WHO BMI was not accompanied by increased risks of adverse outcomes.

CONCLUSIONS

Women in the USA and western Europe have higher prepregnancy BMI and higher rates of GWG above guidelines than women in east Asia. However, when using regional BMI categories in east Asia, rates of GWG above guidelines are similar across the three continents. GWG outside guidelines is associated with adverse outcomes across all regions. If regional BMI categories are used in east Asia, IOM guidelines are applicable in the USA, western Europe and east Asia.

Prospective cohort study of overweight and obesity among rural Indian adults: sociodemographic predictors of prevalence, incidence and remission

OBJECTIVES

To assess sociodemographic predictors of prevalence, incidence and remission of overweight including obesity among adults (aged ≥18 years) in rural Eastern India.

DESIGN

Prospective cohort study.

SETTING

Birbhum Health and Demographic Surveillance System, West Bengal, India.

PARTICIPANTS

Self-weighted sample of 24 115 adults (men: 10915, women: 13200) enrolled in 2008 were followed up for body mass index (BMI) reassessment in 2017.

PRIMARY AND SECONDARY OUTCOME MEASURES

Measured BMI was categorised as: underweight (<18.5 kg/m²), normal weight (18.5-22.9 kg/m²) and overweight including obesity (≥23 kg/m²; hereinafter overweight). Incident overweight was defined as transition from normal weight in 2008 to overweight in 2017, whereas if overweight individuals in 2008 measured normal BMI in 2017, it was classified as remission from overweight.

RESULTS

In 2008, 10.1% of men and 14.6% of women were overweight, whereas 17.3% of men and 24.7% of women were overweight in 2017. At the same time, in 2017, 35.6% of men and 33.3% of women were underweight. Incident overweight was 19.0% among men and 27.2% among women, whereas remission among men was higher (15.4%) than women (11.5%). Women were more likely to be overweight in 2008 and to experience incident overweight than men. For men and women, education level and wealth were positively associated with prevalence and incidence of overweight. Remission from overweight was less likely in Sainthia, a business hub in the district, as compared with Mohammad Bazar, a more rural area.

CONCLUSION

A nutrition transition to higher risk of overweight is evident in this rural setting in India, especially among women and individuals with high socioeconomic status. At the same time, a high prevalence of underweight persists, resulting in a significant double burden. Culturally sensitive interventions that address both ends of the malnutrition spectrum should be prioritised.

Predictors of postpartum weight retention among urban Malaysian mothers: A prospective cohort study

BACKGROUND

Women of childbearing age are predisposed to becoming overweight or obese. This study determines the mean, prevalence and factors associated with 6 months postpartum weight retention among urban Malaysian mothers.

METHODS

A prospective cohort study was conducted at baseline (after delivery), 2, 4 and 6 months postpartum. From 638 eligible mothers initially recruited, 420 completed until 6 months. Dependent variable was weight retention, defined as difference between weight at 6 months postpartum and pre-pregnancy weight, and weight retention ≥5kg was considered excessive. Independent variables included socio-demographic, history of pregnancy and delivery, lifestyle, practices and traditional postpartum practices.

RESULTS

Average age was 29.61±4.71years, majority (83.3%) were Malays, 58.8% (low education), 70.0% (employed), 65.2% (middle income family), 33.8% (primiparous) and 66.7% (normal/instrumental delivery). Average gestational weight gain was 12.90±5.18kg. Mean postpartum weight retention was 3.12±4.76kg, 33.8% retaining ≥5kg. Bivariable analysis showed low income, primiparity, gestational weight gain ≥12kg, less active physically, higher energy, protein, carbohydrate and fat intake in diet, never using hot stone compression and not continuing breastfeeding were significantly associated with higher 6 months postpartum weight retention. From multivariable linear regression analysis, less active physically, higher energy intake in diet, gestational weight gain ≥12kg, not continuing breastfeeding 6 months postpartum and never using hot stone compression could explain 55.1% variation in 6 months postpartum weight retention.

CONCLUSION

Women need to control gestational weight gain, remain physically active, reduce energy intake, breastfeed for at least 6 months and use hot stone compression to prevent high postpartum weight retention.

Postpartum Weight Retention Risk Factors in a Taiwanese Cohort Study

OBJECTIVE

Excess postpartum weight retention (PPWR) is related to long-term weight gain. Therefore, this study was conducted to identify the risk factors for PPWR to provide guidance for preventive strategies.

METHODS

This cohort study surveyed 461 women who gave birth at a medical center between March 2014 and March 2016. The participants completed a questionnaire within 1 month of delivery, and their 6-month postpartum weight was tracked.

RESULTS

The results showed that the mean pre-pregnancy BMI was 21.4 ± 3.3 kg/m2, and the mean gestational weight gain (GWG) was 12.8 ± 4.1 kg. The mean PPWR was 4.6 ± 3.5 kg at 1 month and 2.1 ± 3.3 kg at 6 months. Multivariate analysis revealed that GWG (adjusted OR: 1.92 (1.70-2.17)), pre-pregnancy BMI (adjusted OR: 0.85 (0.77-0.94)), and exclusive breastfeeding (adjusted OR: 0.55 (0.32-0.94)) were significantly correlated with a 1-month PPWR higher than the median value. In addition, GWG (adjusted OR: 1.30 (1.22-1.39)) and exclusive breastfeeding (adjusted OR: 0.37 (0.24-0.58)) were significantly correlated with a 6-month PPWR higher than the median value.

CONCLUSION

Our findings indicate that the key to reducing PPWR is to control GWG and engage in exclusive breastfeeding.

Prevalence of Metabolic Syndrome Markers among Women at 1-year Postpartum as per Prepregnancy Body Mass Index Status: A Longitudinal Study

INTRODUCTION

Maternal body composition (BC) changes during lactation. Increased prepregnancy obesity is associated with poor obstetric outcomes. The aim was to study changes in maternal BC postpartum (PP) to 1-year PP with reference to their prepregnancy body mass index (BMI) status.

METHODS

The study design was a 1-year follow-up study. Sixty-five apparently healthy primiparous women (28.6 ± 3.4 years delivered full-term infants) were randomly selected from December 2010 to June 2013 and postclassified on the basis of their prepregnancy BMI status. Anthropometry, sociodemographic status, physical activity, diet, clinical examination, biochemical tests, and BC at total body (dual energy X-ray absorptiometry, GE, Lunar DPX) were collected using standardized protocols.

RESULTS

Forty-one women were classified in Group A with normal prepregnancy BMI (20.4 ± 2.0 kg/m²) and 24 women in Group B with overweight/obese (OW/OB) prepregnancy BMI (26.1 ± 1.9 kg/m²). At 1 year, 75% of women returned to normal BMI in Group A, whereas all 100% of women from Group B remained in OW category at 1-year PP. Nearly 43% of Group B women showed the presence of at least two metabolic syndrome risk factors as compared to 36% in Group A at 1 year.

CONCLUSION

Women with OW/OB prepregnancy BMI accumulated higher visceral fat with a higher prevalence of metabolic risk factors at 1-year PP. Our study underlines the importance of maintaining BMI status in reference range in reproductive years.

Changes in body composition in apparently healthy urban Indian women up to 3 years postpartum

INTRODUCTION

Dietary and life style practices differ in postpartum (PP) and nonpregnant Indian women. Effect of these practices on postpartum weight retention (PPWR) and development of cardio-metabolic risk (CMR) has been scarcely studied in urban women. Aims of this study were to (i) compare anthropometry, biochemical parameters and body composition up to 3 years PP (ii) effect of PPWR, dietary fat intake and physical activity on CMR factors.

DESIGN

Cross-sectional, 300-fullterm, apparently healthy primi-parous women (28.6 ± 3.4 years) randomly selected. 128 women within 7-day of delivery (Group-A), 88 with 1-2 years (Group-B) and 84 with 3-4-year-old-children (Group-C) were studied. Anthropometry, sociodemographic status, physical activity, diet, clinical examination, biochemical tests, body composition, at total body (TB), by dual energy X-ray absorptiometry (GE-Lunar DPX) were collected.

RESULTS

Women at 3-year PP showed higher weight retention (6.5[10] kg) than at 1-year (3.0[7] kg) (median [IQR]). Android fat % (central obesity) increased (P < 0.05) at 1-year PP (47 ± 10.0%) when compared to 1-week PP (44.3 ± 6.7%) and remained elevated at 3-year PP (45.6 ± 10.2%). Regression analysis revealed that at 1-year PP, increase in PPWR (Odd Ratio [OR] 1.8, 95% confidence interval [CI] = [1.2, 2.5], P < 0.001) and inactivity (OR 1.4, 95% CI= (0.97, 2.0), P < 0.1) were predictors for CMR. At 3-year PP, only PPWR was responsible for increase in CMR parameters (OR 1.6, 95% CI = (1.3, 2.3), P < 0.001) and not inactivity (P > 0.1).

CONCLUSION

Postdelivery, low physical activity and higher PPWR may increase CMR in Indian women.

Transition of maternal and child nutrition in Asia: implications for public health

PURPOSE OF REVIEW

This article reviews the maternal and child nutrition situation in Asia in transition and its public health implications.

RECENT FINDINGS

Countries in Asia are facing a double burden of malnutrition. Accessibility to high energy, less nutrient-dense foods or processed foods affects current dietary patterns, whereas industrialization is leading to more sedentary lifestyles both in rural and urban areas. Stunting and wasting among young children persist but have declined in severity, whereas overweight and obesity have risen rapidly. Growth faltering in height during the first 2 years of life has affected muscle mass accretion, but rapid weight gain after 2 years of age has led to more fat accretion, imposing risks of childhood obesity and consequent metabolic disorders. The number of women entering pregnancy with low BMI has decreased, but increasing BMI is noticeable. Prepregnancy BMI and gestational weight gain are important determinants of maternal nutrition during pregnancy, the risk of gestational diabetes and postpartum weight retention, as well as obesity and diet-related noncommunicable diseases in later adulthood.

SUMMARY

Asia in transition is faced with persistent undernutrition and increasing trends of obesity and metabolic disorders among children and women. The first 1000 days from conception is a critical period, but it is also a window of opportunity for preventing double burden of malnutrition in Asian countries characterized by a nutrition transition.

Correlates of cardiovascular disease risk scores in women in Riyadh, Kingdom of Saudi Arabia

Saudi Arabia has a high prevalence of obesity and physical inactivity. We measured cardiovascular (CVD) risk scores and determined the factors associated with them in women in Riyadh, Saudi Arabia. A cross-sectional study using a self-administered questionnaire was conducted on 291 women aged ≥ 30 years. Information was collected on socio-demographics and physical health status. Anthropometric and blood pressure measurements were taken. Physical activity was measured using Kaiser's Physical Activity Survey and Godin's Leisure Time Exercise questionnaire. CVD risk scores were calculated using the non-laboratory-based Framingham Risk (FRS) prediction model for primary care. FRS scores ranged from 0.50 to 21.9. A total of 2.7% (n = 8) of women had a high FRS score (>20), 5.5% (n = 16) had intermediate scores (11-20), and 91.8% (n = 267) of women had low scores (<10) CVD risk scores. Multiple linear regression results indicated that a one-unit change in physical activity (household/caregiver index), strenuous exercise, waist circumference, number of children, television watching, and knee pain were significantly associated with -0.20 (p < .01), -0.12 (p = .03), 0.19 (p = .001), 0.29 (p < .01), 0.13 (p = .04), and 0.11 (p = .05) unit change in CVD risk scores, respectively. Household activities and strenuous exercise had a protective role in females in relation to CVD risk. Programs recommending physical activity at all levels should be encouraged.

Home-based active video games to promote weight loss during the postpartum period

PURPOSE

Weight retention during the postpartum period is critical for the later development of obesity in women. Traditional physical activity is frequently discontinued because of incompatibility with mothers' agenda (i.e., baby care). In the present study, active video games (AVG) are proposed for postpartum women to improve their body composition.

METHODS

Thirty-four postpartum women (body mass index = 24.5 ± 3.4 kg·m) were randomized to an AVG group or a control group. Subjects assigned to the AVG group were given a Wii Nintendo console with the game Wii Fit Plus for 40 d. The two groups were tested for weight, body mass index, body fat mass, waist and hip circumferences, and other anthropometric parameters. Physical fitness, energy expenditure, energy intake, and adverse events were also investigated.

RESULTS

The AVG group lost more weight than the control group (-2.2 ± 0.9 vs. -0.5 ± 0.7 kg, P < 0.001). They also exhibited more important reductions of BMI, waist and hip circumferences, and body fat (P < 0.05). During the 40-d period, subjects expended an estimated 4682 ± 2874 kcal just by playing AVG. Daily energy intake was reduced by 206 ± 559 kcal. There were significant positive correlations between playing frequency, total playing time, total energy expenditure during the 40-d period, and decrease in daily energy intake respectively, and weight loss (P < 0.05). Playing time data suggested no conflict with baby care activities.

CONCLUSIONS

AVGs could represent an interesting spare physical activity for postpartum women. In the present study, these games promoted physical activity, induced a reduction of energy intake, and subsequently minimized weight retention.

Determining optimal gestational weight gain in a multiethnic Asian population

AIM

To define the optimal gestational weight gain (GWG) for the multiethnic Singaporean population.

METHODS

Data from 1529 live singleton deliveries was analyzed. A multinomial logistic regression analysis, with GWG as the predictor, was conducted to determine the lowest aggregated risk of a composite perinatal outcome, stratified by Asia-specific body mass index (BMI) categories. The composite perinatal outcome, based on a combination of delivery type (cesarean section [CS], vaginal delivery [VD]) and size for gestational age (small [SGA], appropriate [AGA], large [LGA]), had six categories: (i) VD with LGA; (ii) VD with SGA; (iii) CS with AGA; (iv) CS with SGA; (v) CS with LGA; (vi) and VD with AGA. The last was considered as the 'normal' reference category. In each BMI category, the GWG value corresponding to the lowest aggregated risk was defined as the optimal GWG, and the GWG values at which the aggregated risk did not exceed a 5% increase from the lowest aggregated risk were defined as the margins of the optimal GWG range.

RESULTS

The optimal GWG by pre-pregnancy BMI category, was 19.5 kg (range, 12.9 to 23.9) for underweight, 13.7 kg (7.7 to 18.8) for normal weight, 7.9 kg (2.6 to 14.0) for overweight and 1.8 kg (-5.0 to 7.0) for obese.

CONCLUSION

The results of this study, the first to determine optimal GWG in the multiethnic Singaporean population, concur with the Institute of Medicine (IOM) guidelines in that GWG among Asian women who are heavier prior to pregnancy, especially those who are obese, should be lower. However, the optimal GWG for underweight and obese women was outside the IOM recommended range.

Adiposity and hyperglycaemia in pregnancy and related health outcomes in European ethnic minorities of Asian and African origin: a review

BACKGROUND

Ethnic minorities in Europe have high susceptibility to type 2 diabetes (T2DM) and, in some groups, also cardiovascular disease (CVD). Pregnancy can be considered a stress test that predicts future morbidity patterns in women and that affects future health of the child.

OBJECTIVE

TO REVIEW ETHNIC DIFFERENCES IN: 1) adiposity, hyperglycaemia, and pre-eclampsia during pregnancy; 2) future risk in the mother of obesity, T2DM and CVD; and 3) prenatal development and possible influences of maternal obesity, hyperglycaemia, and pre-eclampsia on offspring's future disease risk, as relevant for ethnic minorities in Europe of Asian and African origin.

DESIGN

Literature review.

RESULTS

Maternal health among ethnic minorities is still sparsely documented. Higher pre-pregnant body mass index (BMI) is found in women of African and Middle Eastern descent, and lower BMI in women from East and South Asia compared with women from the majority population. Within study populations, risk of gestational diabetes mellitus (GDM) is considerably higher in many minority groups, particularly South Asians, than in the majority population. This increased risk is apparent at lower BMI and younger ages. Women of African origin have higher risk of pre-eclampsia. A GDM pregnancy implies approximately seven-fold higher risk of T2DM than normal pregnancies, and both GDM and pre-eclampsia increase later risk of CVD. Asian neonates have lower birth weights, and mostly also African neonates. This may translate into increased risks of later obesity, T2DM, and CVD. Foetal overgrowth can promote the same conditions. Breastfeeding represents a possible strategy to reduce risk of T2DM in both the mother and the child.

CONCLUSIONS

Ethnic minority women in Europe with Asian and African origin and their offspring seem to be at increased risk of T2DM and CVD, both currently and in the future. Pregnancy is an important window of opportunity for short and long-term disease prevention.
