Validation of Obstetric Diagnosis and Procedure Codes in the Danish National Patient Registry in 2017.

Purpose: This study aimed to systematically evaluate the validity of variables related to pregnancy, delivery, and key characteristics of the infant in the Danish National Patient Register using maternal medical records as the reference standard. Patients and Methods: We reviewed medical records of 1264 women giving birth in the Region of Southern Denmark during 2017. We calculated positive (PPV) and negative (NPV) predictive values, sensitivity, and specificity to estimate the validity of 49 selected variables. Results: The PPV was ≥0.90 on most pregnancy-related variables including parity, pre-gestational BMI, diabetes disorders, and previous cesarean section, while it was lower for hypertensive disorders, especially mild to moderate preeclampsia (0.49, 95% CI 0.32-0.66). Sensitivity ranged from 0.80 to 1.00 on all pregnancy-related variables, except hypertensive disorders (sensitivity 0.38-0.71, lowest for severe preeclampsia). On most delivery-related variables including obstetric surgical procedures (eg cesarean section and induction of labor), pharmacological pain-relief, and gestational age at delivery, PPV's ranged from 0.98 to 1.00 and the corresponding sensitivities from 0.87 to 1.00. Regarding infant-related variables, both the APGAR score registered five minutes after delivery and birthweight yielded a PPV of 1.00. Conclusion: Obstetric coding in the Danish National Patient Register shows very high validity and completeness making it a valuable source for epidemiologic research.

Kidney Disease in Women With Previous Gestational Diabetes Mellitus: A Nationwide Register-Based Cohort Study.

OBJECTIVE: The association between gestational diabetes mellitus (GDM) and incident kidney disease, the mediating effects of diabetes and hypertension, and the impact of severity of metabolic dysfunction during pregnancy on the risk of incident kidney disease were investigated in this study. RESEARCH DESIGN AND METHODS: This Danish, nationwide, register-based cohort study included all women giving birth between 1997 and 2018. Outcomes included chronic kidney disease (CKD) and acute kidney disease, based on diagnosis codes. Cox regression analyses explored the association between GDM and kidney disease. A proxy for severity of metabolic dysfunction during pregnancy was based on GDM diagnosis and insulin treatment during GDM in pregnancy and was included in the models as an interaction term. The mediating effects of subsequent diabetes and hypertension prior to kidney disease were quantified using mediation analyses. RESULTS: Data from 697,622 women were used. Median follow-up was 11.9 years. GDM was associated with higher risk of CKD (adjusted hazard ratio [aHR] 1.92; 95% CI 1.67-2.21), whereas acute kidney disease was unrelated to GDM. The proportions of indirect effects of diabetes and hypertension on the association between GDM and CKD were 75.7% (95% CI 61.8-89.6) and 30.3% (95% CI 25.2-35.4), respectively, as assessed by mediation analyses. The CKD risk was significantly increased in women with insulin-treated GDM and no subsequent diabetes compared with women without GDM (aHR 2.35; 95% CI 1.39-3.97). CONCLUSIONS: The risk of CKD was significantly elevated after GDM irrespective of subsequent development of diabetes and hypertension. Furthermore, women with severe metabolic dysfunction during pregnancy had the highest CKD risk.

Health promotion intervention among women with recent gestational diabetes mellitus: penetration, participation, and baseline findings from the Face-it randomized controlled trial.

INTRODUCTION: Face-it is a randomized controlled trial for women with recent gestational diabetes mellitus (GDM) and their families designed to evaluate the effect of a health promotion intervention on type 2 diabetes mellitus (T2DM) risk and quality of life. This study examined (1) the penetration and participation rates for the Face-it trial, (2) the characteristics of the participating women and the potential differences in characteristics according to partner participation status, and (3) representativity of the women at baseline. RESEARCH DESIGN AND METHODS: We identified women with GDM during pregnancy and invited them and their partners to a baseline examination 10-14 weeks after delivery. Representativity was assessed by comparing the baseline participants with non-participating women, the general population of women with GDM delivering in Denmark, and populations from other intervention trials. RESULTS: The penetration rate was 38.0% (867/2279) and the participation rate was 32.9% (285/867). The 285 women who attended baseline had a mean age of 32.7 (±4.8) years and body mass index (BMI) of 28.1 (±5.4) kg/m2, and 69.8% had a partner who participated. The women participating with a partner were more often primiparous, born in Denmark (82.8% vs 68.2%), were younger, and more often had a BMI ≤24.9 kg/m2 (35.7% vs 21.2%) compared with women without a partner. Compared with the general population of women with GDM in Denmark, these women broadly had similar degree of heterogeneity, but had higher rates of primiparity and singleton deliveries, and lower rates of preterm delivery and prepregnancy obesity. CONCLUSIONS: The penetration and participation rates were acceptable. We found a high rate of partner participation. Overall, women participating with a partner were comparable with those participating without a partner. Participating women were broadly similar to the general national GDM population, however with prepregnancy obesity, multiparity, preterm delivery, and multiple pregnancy being less represented.

Barriers and facilitators for sustainable weight loss in the pre-conception period among Danish women with overweight or obesity - a qualitative study.

BACKGROUND: The prevalence of overweight or obesity in women of reproductive age continues to increase. A high pre-pregnancy body mass index (BMI) has been shown to increase the risk of pregnancy complications and predispose offspring to childhood obesity. However, little is known about factors affecting women's ability to achieve sustainable weight management and very few studies have applied behavior change theory to qualitative data. AIM: This study aimed to explore barriers and facilitators for weight management among women with overweight or obesity, who wanted to lose weight before pregnancy. METHODS: We conducted semi-structured interviews with 17 women with a BMI ≥ 27 kg/m2, who planned to become pregnant in the near future. Data were analyzed using an abductive approach and the Capability, Opportunity, Motivation, and Behavior model was applied as a conceptual framework. RESULTS: The women's strongest motivator for pre-conception weight loss was their ability to become pregnant. Barriers to successful weight management included their partners' unhealthy behaviors, mental health challenges, competing priorities, and internalized weight stigmatization. The women described careful planning, partners' health behaviors, social support, and good mental health as facilitators for sustainable weight management. CONCLUSION: Our study provides insights into factors affecting weight management among women with overweight or obesity in the pre-conception period. Future interventions on weight management require a holistic approach, including a focus on social support, especially from the partner, and mental health, as well as an effort to limit internalized weight stigma.

Psychiatric Morbidity in Women With Previous Gestational Diabetes Mellitus: A Nationwide Register-Based Cohort Study.

OBJECTIVE: To investigate associations between previous gestational diabetes mellitus (GDM) and incident psychiatric morbidity, and to explore the role of subsequent diabetes development in psychiatric morbidity risk. RESEARCH DESIGN AND METHODS: A nationwide register-based cohort study including all women delivering in Denmark from 1997 to 2018 was conducted. GDM exposure was based on diagnosis code, whereas psychiatric morbidity outcome was based on diagnosis code and psychopharmacological medication use. Multiple Cox regression and mediation analyses were performed. RESULTS: In a study population of 660,017 women, previous GDM was associated with increased risk of depression based on diagnosis code and/or medication use (adjusted hazard ratio [aHR] 1.22 [95% CI 1.18-1.27]), any psychiatric diagnosis (aHR 1.20 [95% CI 1.13-1.27]), and any psychopharmacological medication use (aHR 1.21 [95% CI 1.17-1.25]). Moreover, risk of depressive and anxiety disorders, as well as antidepressant and antipsychotic medication use, was increased, with aHRs ranging from 1.14 (95% CI 1.05-1.25) to 1.32 (95% CI 1.22-1.42). No associations were found regarding substance use disorders, psychotic disorders, bipolar disorders, postpartum psychiatric disease, or anxiolytic medication use. Psychiatric morbidity risk was higher in women with versus without subsequent diabetes development. However, GDM history affected risk estimates only in women without subsequent diabetes. Subsequent diabetes mediated 35-42% of the associations between GDM and psychiatric morbidity. CONCLUSIONS: GDM was associated with increased psychiatric morbidity risk. Subsequent diabetes development played a significant role in future psychiatric morbidity risk after GDM, although it only partly explained the association.

The development of an IT-based intervention to support a healthy postpartum lifestyle through behavioral change.

Background: Pregnancy and the postpartum period are difficult times with increased risks of weight gain and weight retention. This study aims to provide new insights into developing and designing information an communication technology interventions to support a healthy postpartum lifestyle through behavioral changes.Methods: A participatory design approach, combined with the behavior change wheel, was applied. The intervention was based on outcomes from co-creation with postpartum parents, healthcare professionals, IT consultants, and researchers.Results: An intervention was developed that reflects users' requests and needs to support a healthy postpartum lifestyle through behavioral change. The intervention includes podcasts, video exercises, weight tracking, and weekly push notifications.Conclusion: Developing an intervention to support a healthy postpartum lifestyle is feasible using both a participatory design and the behavior change wheel.

Cardiovascular and metabolic morbidity in women with previous gestational diabetes mellitus: a nationwide register-based cohort study.

BACKGROUND: Gestational diabetes mellitus (GDM) is associated with adverse pregnancy outcomes and has maternal health implications reaching beyond the perinatal period. We aimed to investigate the incidence and severity of cardiovascular and metabolic morbidity in women with previous GDM in a Danish population and to study whether proxies of impaired beta cell function-insulin treatment during GDM pregnancy and development of subsequent manifest diabetes mellitus-influence incident risk of cardiovascular and metabolic morbidity. METHODS: A nationwide register-based cohort study was conducted on the complete cohort of 700,648 women delivering in Denmark during 1997-2018. The exposure variable was GDM and primary outcome was overall cardiovascular and metabolic morbidity. Secondary outcomes were major cardiovascular disease (ischemic heart disease, heart failure, and/or stroke/transient cerebral ischemia), hypertension, dyslipidemia, and venous thrombosis. Severity of morbidity was assessed using number of hospital contacts with diagnosis codes related to cardiovascular and metabolic morbidity and number of redemptions of prescribed medication related to cardiovascular and metabolic morbidity in women who developed cardiovascular and metabolic morbidity after pregnancy. RESULTS: The median follow-up period was 10.2-11.9 years with a total range of 0-21.9 years. GDM was associated with increased risk of any cardiovascular and metabolic morbidity (adjusted HR 2.13 [95% CI 2.07-2.20]), major cardiovascular disease (adjusted HR 1.69 [95% CI 1.55-1.84]), hypertension (adjusted HR 1.89 [95% CI 1.82-1.96], dyslipidemia (adjusted HR 4.48 [95% CI 4.28-4.69]), and venous thrombosis (adjusted HR 1.32 [95% CI 1.16-1.50]). Insulin treatment during pregnancy and subsequent development of manifest diabetes exacerbated the risk estimates. Previous GDM was associated with more hospital contacts and more redeemed prescriptions in women developing cardiovascular and metabolic morbidity (p < 0.001). CONCLUSIONS: Previous GDM was associated with significantly higher risk of cardiovascular and metabolic morbidity, especially incident dyslipidemia. Risks were exacerbated by proxies of beta cell impairment. Severity of morbidity was significantly worse if GDM preceded cardiovascular and metabolic morbidity.

Long-Term Metabolic Outcomes after Gestational Diabetes Mellitus (GDM): Results from the Odense GDM Follow-Up Study (OGFUS).

Aims: To compare metabolic profiles and the long-term risk of metabolic dysfunction between women with previous gestational diabetes mellitus (pGDM) and women without pGDM (non-GDM) matched on age, prepregnancy body mass index (BMI), and parity. Methods: In total, 128 women with pGDM (median follow-up: 7.8 years) and 70 non-GDM controls (median follow-up: 10.0 years) completed a 2 h oral glucose tolerance test (OGTT) with assessment of glucose, C-peptide, insulin, and other metabolic measures. Additionally, anthropometrics, fat mass, and blood pressure were assessed and indices of insulin sensitivity and beta cell function were calculated. Results: The prevalence of type 2 diabetes mellitus (T2DM) was significantly higher in the pGDM group compared to the non-GDM group (26% vs. 0%). For women with pGDM, the prevalence of prediabetes (38%) and the metabolic syndrome (MetS) (59%) were approximately 3-fold higher than in non-GDM women (p's < 0.001). Both insulin sensitivity and beta cell function were significantly reduced in pGDM women compared to non-GDM women. Conclusion: Despite similar BMI, women with pGDM had a substantially higher risk of developing T2DM, prediabetes, and the MetS compared to controls. Both beta cell dysfunction and reduced insulin sensitivity seem to contribute to this increased risk.

Systematically developing a family-based health promotion intervention for women with prior gestational diabetes based on evidence, theory and co-production: the Face-it study.

BACKGROUND: Women with prior gestational diabetes mellitus (GDM) are at high risk of developing type 2 diabetes; however, this risk can be reduced by engaging in positive health behaviours e.g. healthy diet and regular physical activity. As such behaviours are difficult to obtain and maintain there is a need to develop sustainable behavioural interventions following GDM. We aimed to report the process of systematically developing a health promotion intervention to increase quality of life and reduce diabetes risk among women with prior GDM and their families. We distil general lessons about developing complex interventions through co-production and discuss our extensions to intervention development frameworks. METHODS: The development process draws on the Medical Research Council UK Development of complex interventions in primary care framework and an adaptation of a three-stage framework proposed by Hawkins et al. From May 2017 to May 2019, we iteratively developed the Face-it intervention in four stages: 1) Evidence review, qualitative research and stakeholder consultations; 2) Co-production of the intervention content; 3) Prototyping, feasibility- and pilot-testing and 4) Core outcome development. In all stages, we involved stakeholders from three study sites. RESULTS: During stage 1, we identified the target areas for health promotion in families where the mother had prior GDM, including applying a broad understanding of health and a multilevel and multi-determinant approach. We pinpointed municipal health visitors as deliverers and the potential of using digital technology. In stage 2, we tested intervention content and delivery methods. A health pedagogic dialogue tool and a digital health app were co-adapted as the main intervention components. In stage 3, the intervention content and delivery were further adapted in the local context of the three study sites. Suggestions for intervention manuals were refined to optimise flexibility, delivery, sequencing of activities and from this, specific training manuals were developed. Finally, at stage 4, all stakeholders were involved in developing realistic and relevant evaluation outcomes. CONCLUSIONS: This comprehensive description of the development of the Face-it intervention provides an example of how to co-produce and prototype a complex intervention balancing evidence and local conditions. The thorough, four-stage development is expected to create ownership and feasibility among intervention participants, deliverers and local stakeholders.

[Treatment of incidentally found group B streptococcus in urine of pregnant women].

Group B streptococcus (GBS) is a group of naturally occurring bacteria that colonises the anogenital region of every third pregnant woman. From the anogenital region they can colonise the urine and cause bacteriuria. It is well documented that treatment of GBS-bacteriuria with more than 104 colony forming units per millilitre (CFU/ml) reduces the risk of maternal and neonatal morbidity. There is, however, no clear evidence as summarised in this review that GBS-bacteriuria more than 104 CFU/ml increases the risk of maternal and neonatal morbidity which is why no treatment is warranted.

Barriers to a healthy postpartum lifestyle and the possibilities of an information technology-based intervention: A qualitative study.

BACKGROUND: Being overweight or obese is associated with higher risk of adverse maternal and fetal outcomes, including gestational diabetes and childhood obesity. Many women exceed the gestational weight gain recommendations. Thus, it is important to focus on the women's lifestyle between their pregnancies to lower the risk of weight retention before the next pregnancy as well as in a life course perspective. OBJECTIVE: The objective of this study was to explore barriers postpartum women experience with respect to a healthy lifestyle during the postpartum period, and to assess whether an IT-based intervention might be a supportive tool to assist and motivate postpartum women to healthy lifestyle. METHOD: A systematic text condensation was applied to semi-structured focus groups. Five focus group interviews were carried out with a total of 17 postpartum women and two interviews with a total of six health professionals. Participants were recruited through the municipality in Svendborg, Denmark, and at Odense University Hospital in Odense, Denmark, during a four-month period in early 2018. The results were analysed within the frame of the capability, opportunity, motivation and behaviour model (COM-B). RESULTS: From the women's perspective, better assistance is needed from the health professionals to obtain or maintain a healthy lifestyle. The women need tools that inform and help them understand and prioritize own health related risks, and to motivate them to plan and take care of their own health. There is room for engaging the partner more in the communication related to the baby and family's lifestyle. Lastly, the women already use audiobooks and podcasts to obtain information. CONCLUSION: Postpartum women need tools that inform and motivate for a healthy lifestyle postpartum. The tools should allow access to high quality information from health care professionals when the information is needed and also allow engagement from the partner. An IT-based intervention could be a way to support and motivate postpartum women for a healthy lifestyle.

Effectiveness of fetal scalp stimulation test in assessing fetal wellbeing during labor, a retrospective cohort study.

BACKGROUND: It is discussed whether fetal scalp stimulation (FSS) test is a reliable complimentary tool to cardiotocography (CTG) to assess fetal wellbeing during labor. The test is based on the assumption that a well-oxygenated fetus, in contrast to the depressed fetus, will respond to a certain stimulus. The aim of this study was to investigate the effectiveness of the FSS-test. METHODS: A retrospective observational study carried out Copenhagen University Hospital, Herlev, Denmark. Laboring women with singleton pregnancies in cephalic presentation after gestation week 33 and indication for fetal blood sampling (FBS) were eligible for inclusion. The FSS-test was classified as positive when an acceleration was absent at the time of FBS and negative when an acceleration was present. Lactate in scalp blood was measured by the point-of-care device LactatePro™ and pH in artery umbilical cord blood by the stationary blood gas analyzer ABL800. Lactate level < 4.2 mmol/L in scalp blood and arterial cord pH > 7.1 were cut-offs for normality. RESULTS: Three hundred eighty-five women were included. The cohort was divided by the FBS-to-delivery time: Group 1 (n = 128) ≤ 20 min, Group 2 (n = 117) 21-59 min and Group 3 (n = 140) ≥ 60 min. The proportion of FSS-positive tests differed significantly between the groups (p < 0.000). In Group 1 the sensitivity, specificity and likelihoods for scalp lactate ≥4.2 mmol/L were 81.5 (95% CI 67-90.1), 13.3 18.5 (95% CI 5.9-24.6), LHR+ 0.94 (95% CI 0.8-1.1) and LHR - 1.4 (95% CI 0.6-3.2) and for umbilical artery pH ≤ 7.10 the values were 82.6% (95% CI 61.2-95.1), 16% (95% CI 9.4-24.7), 1.0 (95% CI 0.8-1.2) and 1.1 (95% CI 0.4-3) respectively. Regardless of the FBS-to-delivery time the LHR+ for lactate ≥4.2 mmol/L increased to 1.38 (95% CI 1.2-1.6). CONCLUSION: The effectiveness of scalp stimulation test was poor for both ruling in and out fetal hypoxia during labor. Absence of a provoked acceleration seems to be a normal phenomenon in the second stage of labor.

Protocol for a randomised controlled trial of a co-produced, complex, health promotion intervention for women with prior gestational diabetes and their families: the Face-it study.

BACKGROUND: Gestational diabetes mellitus (GDM) is associated with an increased risk of future diabetes in both mother, father and offspring. More knowledge is needed about how to effectively reduce the risk of diabetes through sustained behavioural interventions in these families. The Face-it intervention is a complex health promotion intervention embedded in multi-level supportive environments. The aim of the intervention is to reduce type 2 diabetes risk and increase quality of life among families in the first year following a GDM-affected pregnancy by promoting physical activity, healthy dietary behaviours and breastfeeding through a focus on social support, motivation, self-efficacy, risk perception and health literacy. METHODS: This national multicentre study is a two-arm randomised controlled trial including 460 women with GDM in a ratio of 2 (intervention):1 (usual care). The Face-it intervention consists of three main components: 1) additional visits from municipal health visitors, 2) digital health coaching tailored to family needs and 3) a structured cross-sectoral communication system in the health care system. The intervention runs from 3 to 12 months after delivery. The primary outcome is maternal body mass index at 12 months after delivery as a proxy for diabetes risk. The women will be examined at baseline and at follow-up, and this examination will include blood tests, oral glucose tolerance test (OGTT), anthropometrics, blood pressure, self-reported diet and physical activity, breastfeeding, quality of life, health literacy, physical and mental health status, risk perception and social support. Aside from those data collected for OGTT and breastfeeding and offspring parameters, the same data will be collected for partners. Data on offspring anthropometry will also be collected. Information on pregnancy- and birth-related outcomes will be derived from the medical records of the woman and child. DISCUSSION: This randomised controlled trial seeks to demonstrate whether the Face-it intervention, addressing the individual, family and health care system levels, is superior to usual care in reducing diabetes risk for mothers and their families. Coupled with a process evaluation and an economic analysis, the study will provide evidence for policymakers and health services about health promotion among families affected by GDM and the potential for reducing risk of type 2 diabetes and associated conditions.

Recent advances in cultivation-independent molecular-based techniques for the characterization of vaginal eubiosis and dysbiosis.

"The bacterial vaginosis syndrome" has significant adverse effects for women and babies, including preterm birth and increased risk of acquisition of sexually transmitted infections and HIV. Currently, the gold standard for diagnosis is Gram stain microscopy of vaginal secretions, which is not readily available, is somewhat subjective, and does not differentiate between the likely different subtypes of vaginal dysbioses that may have different etiologies, microbiology, responses to antibiotics, and phenotypic outcomes. With new information from molecular-based, cultivation-independent studies, there is increasing interest in the use of molecular techniques for the diagnosis of bacterial vaginosis. We reviewed the current evidence on and the rationale behind the use of molecular techniques for the diagnosis of bacterial vaginosis. We found a number of commercially available molecular diagnostic tests, a few of which have US Food and Drug Administration (FDA) and/or Conformité Européenne in vitro diagnostic (CE-IVD) approval, and we have compared their performance with respect to sensitivities and specificities. Molecular-based tests have the advantage of objectivity, quantification, detection of fastidious organisms, and validity for self-obtained vaginal swabs. The performance of the molecular tests against standard microscopy is impressive, but further education of users on interpretation is needed. Bacterial vaginosis is the major cause of vaginal dysbiosis and should be recognized for the threat it is to women's genital tract health. Quantitative assessment of microbial abundance, the diversity of other organisms present, specific primers for gene sequence regions, and clades and biovars of target microbes should be recognized and incorporated into future molecular diagnostic tests to better differentiate between vaginal eubiosis and dysbiosis.

Lifestyle interventions to maternal weight loss after birth: a systematic review.

BACKGROUND: Over the past decades, there has been an increase in overweight and obesity in women of childbearing age, as well as the general population. Overweight and obesity are related to a later, increased risk of type 2 diabetes and cardiovascular diseases. Increasing weight between pregnancies has a negative impact on the development of the fetus in a subsequent pregnancy. It is also related to long-term obesity and overweight for the woman. Accordingly, weight control in women of the childbearing age is important for both women and their offspring. Information and communication technology (ICT) has become an integrated part of many peoples' lives, and it has the potential to prevent disease. In this systematic review, we summarize the evidence from randomized controlled trials to compare effects of different ICT-based interventions to support postpartum women to achieve weight loss. METHODS: A systematic search was performed in PubMed, Embase, PsycInfo, CINAHL, Web of Science, Scopus, and Cochrane, searching on terms, such as postpartum, weight loss, telemedicine, and randomized controlled trials. Two independent researchers undertook study selection and data extraction. Results were reported narratively. The systematic review only included studies that were randomized controlled trials. RESULTS: Eight studies were included in the systematic review. All of them were characterized by applying one or more ICT components to assist postpartum women in weight control, and had weight loss as an outcome measure. A significant difference was found in weight loss between control group and intervention group in the majority of the studies. However, five of the studies had a relatively short follow-up period (40 days to 16 weeks), six of the studies had a relatively small sample size (18 to 66 women), and half of the studies indicated challenges with adherence to the interventions over time. CONCLUSION: ICT-based interventions can support postpartum women to achieve a healthy lifestyle and weight control. Future studies should focus on larger sample sizes, longer follow-up periods, and adherence to the interventions. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42018080731.

[Acquired clitoral phimosis causing a periclitoral pseudocyst].

Clitoral phimosis or preputial fusion may occur as a result of atrophic vaginitis among other conditions. A 72-year-old woman presented with atrophic vaginitis, preputial fusion, and a painful periclitorial pseudocyst. We suggest that a minimal surgery approach in a manual retraction of the synarchies without making an incision is a gentle and effective surgical management of preputial fusion. Suturing the ends from each other combined with continuous topical prophylaxis will minimise the risk of recurrence of pseudo-cyst and prevent worsening scar tissue formation.

Targeting pregnancy as a time to treat obesity.

Maternal obesity is recognized as one of the largest contributors to compromised health during pregnancy. Lifestyle interventions in obese pregnant women may be able to reduce gestational weight gain (GWG) but have shown limited success in improving pregnancy and neonatal outcomes. Lack of statistical power, poor compliance and inconsistency in inclusion BMI and setting across studies may be some of the reasons. Since pregestational BMI is the single most important predictor of obesity-related complications, the metabolic profile in the first trimester of pregnancy may play a very important role. Observational studies have shown that interpregnancy weight loss reduces the risk of macrosomia in a subsequent pregnancy. Future lifestyle randomized controlled trials should target the prepregnant state and examine the effect on maternal and neonatal outcomes.

Postpartum weight retention and breastfeeding among obese women from the randomized controlled Lifestyle in Pregnancy (LiP) trial.

OBJECTIVES: To study the effects of lifestyle intervention in pregnancy on weight retention 6 months postpartum among obese women from the "Lifestyle in Pregnancy" (LiP) study, and to determine associations between breastfeeding with postpartum maternal weight. DESIGN: Six months postpartum follow up after a randomized controlled intervention trial. SETTING: Two university hospitals in Denmark. POPULATION: A total of 360 women with pregestational body mass index ≥30 kg/m(2) . METHODS: The intervention involved lifestyle changes (diet and exercise) during pregnancy. The control group received routine pregnancy care. Both groups received standard postnatal care. MAIN OUTCOME MEASURES: Gestational weight gain, postpartum weight retention and breastfeeding. RESULTS: Follow up was completed in 238 women of whom 46% in the intervention group and 57% in the control group had retained weight 6 months postpartum (p = 0.088). Women with gestational weight gain ≤9 kg, (recommended by the Institute of Medicine), retained less postpartum weight compared with those who exceeded 9 kg (median -0.7 vs. 1.5, p < 0.001). Ninety-two percent in both weight gain groups initiated breastfeeding. The number of breastfeeding mothers was higher among women with postpartum weight retention ≤5 kg compared with those with weight retention > 5 kg (94% vs. 85%, p = 0.034). CONCLUSIONS: We could not detect sustained weight control at 6 months postpartum despite a lower gestational weight gain for obese women during pregnancy who received a lifestyle intervention rather than standard care. Women who adhered to gestational weight gain recommendations had significantly lower postpartum weight retention. Breastfeeding for 6 months was negatively associated with postpartum weight retention.
