High prevalence of medical conditions and unhealthy lifestyle behaviours in women with PCOS during preconception: findings from the Australian Longitudinal Study on Women's Health.

STUDY QUESTION: What are the pre-existing medical conditions and lifestyle behaviours of women with and without PCOS during the preconception period? SUMMARY ANSWER: During the preconception period, medical conditions of obesity, depression, anxiety, and a history of infertility were more highly prevalent in women with than without PCOS, and more women with than without PCOS were engaged in unhealthy lifestyle behaviours. WHAT IS KNOWN ALREADY: Women with PCOS are predisposed to infertility and pregnancy complications. Optimizing preconception medical health and lifestyle behaviours can improve maternal and pregnancy outcomes but, to the best of our knowledge, no study has examined the preconception medical conditions and lifestyle behaviours of women with PCOS. STUDY DESIGN, SIZE DURATION: This is a cross-sectional study on 942 women with PCOS and 7024 women without PCOS, aged 24-30 years from the Australian Longitudinal Study of Women's Health, an ongoing, national survey-based prospective cohort study. PARTICIPANTS/MATERIALS, SETTING, METHODS: The current study analysed self-reported data from Survey 6 collected in 2019 of the cohort of women born between 1989 and 1995. Explored outcomes included BMI, pre-existing medical conditions, and modifiable lifestyle behaviours, including smoking, recreational drug use, alcohol intake, and physical activity level, during the preconception period. Differences between subgroups were tested using Student's t-test, χ2 test, or Fisher's exact test as appropriate. The associations of pregnancy intention with medical conditions and lifestyle behaviours were examined using logistic regression. MAIN RESULTS AND THE ROLE OF CHANCE: Obesity, depression, anxiety, and infertility were highly prevalent in women actively planning for pregnancy. Among women with PCOS, the prevalence of obesity was 47.02%, followed by depression at 32.70%, anxiety at 39.62%, and infertility at 47.17%. Conversely among women without PCOS, the corresponding prevalence was lower, at 22.33% for obesity, 18.98% for depression, 23.93% for anxiety, and 16.42% for infertility. In women actively planning for pregnancy, only those without PCOS demonstrated a lower prevalence of unhealthy lifestyle behaviours compared to non-planning women. The prevalence of unhealthy lifestyle behaviours was similar in women with PCOS regardless of their pregnancy intentions. Multivariable logistic regression revealed that only moderate/high stress with motherhood/children (adjusted odds ratio (OR) 3.31, 95% CI 1.60-6.85) and history of infertility (adjusted OR 9.67, 95% CI 5.02-18.64) were significantly associated with active pregnancy planning in women with PCOS. LIMITATIONS, REASONS FOR CAUTION: The findings were based on self-reported data. The cohort of women surveyed may have a higher level of education than women in the community, therefore our findings may underestimate the true prevalence of pre-existing medical conditions and lifestyle challenges faced by the broader population. WIDER IMPLICATIONS OF THE FINDINGS: A higher proportion of women with than without PCOS had pre-existing medical conditions and engaged in potentially modifiable unhealthy lifestyle behaviours during preconception despite their risk for subfertility and pregnancy complications. Healthcare professionals play a pivotal role in guiding this high-risk group of women during this period, offering counselling, education, and support for the adoption of healthy lifestyles to improve fertility, pregnancy outcomes, and intergenerational health.

Clinical management of pregnancy in women with polycystic ovary syndrome: An expert opinion.

Polycystic ovary syndrome (PCOS) is associated with a higher risk for pregnancy and birth complications according to the specific features associated with PCOS. The features include obesity before and during pregnancy, hyperandrogenism, insulin resistance, infertility, cardiometabolic risk factors, and poor mental health. PCOS is not often recognized as a risk factor for poor pregnancy and birth outcomes in pregnancy care guidelines, while its associated features are. Pregnancy-related risk profile should ideally be assessed for modifiable risk factors (e.g., lifestyle and weight management) at preconception in women with PCOS. Hyperglycaemia should be screened using a 75-g oral glucose tolerance test at preconception or within the first 20 weeks of pregnancy if it has not been performed at preconception and should be repeated at 24-28 weeks of pregnancy. In the absence of evidence of benefit for strategies specific to women with PCOS, the international evidence-based guidelines for the assessment and management of PCOS recommend screening, optimizing, and monitoring risk profile in women with PCOS (at preconception, during and postpregnancy) consistent with the recommendations for the general population. Recommended factors include blood glucose, weight, blood pressure, smoking, alcohol, diet, exercise, sleep and mental health, emotional, and sexual health among women with PCOS. The guidelines recommend Metformin in addition to lifestyle for assisting with weight management and improving cardiometabolic risk factors, particularly in those with overweight or obesity. Letrozole is considered the first-line pharmacological treatment for anovulatory infertility in PCOS. Individualized approach should be considered in the management of pregnancy in PCOS.

Predictors of hypertensive disorders in pregnancy in women with and without polycystic ovary syndrome: The Australian Longitudinal Study of Women's Health.

OBJECTIVES: A higher risk of hypertensive disorders in pregnancy (HDP) is frequently reported in women with polycystic ovary syndrome (PCOS). These women, however, have a higher risk profile for HDP compared with women without PCOS. The aim of this study was to elucidate the impact of PCOS per se on the incidence of HDP through post hoc subgroup analyses of the Australian Longitudinal Study on Women's Health by level of risk. DESIGN: Longitudinal study. PATIENTS: Of a total of 14,247 participants, 5838 women met the inclusion criteria. Eligible women were required to report PCOS and HDP status in at least one pregnancy within the study. MEASUREMENTS: Included risk factors were age, body mass index, country of birth, parity, multiple pregnancy, subfertility, infertility treatment (hormonal vs. in vitro fertilization), gestational diabetes (GDM), family history of GDM and socioeconomic status. Longitudinal association between PCOS and HDP was assessed the using Cox proportional hazard regression with Efron's method. RESULTS: While PCOS was associated with a higher incidence of HDP in a univariate model [hazard ratio (HR): 1.34, 95% confidence interval (CI): 1.05, 1.72], the significance was not retained after adjustment for risk factors [HR: 1.19, 95% CI: 0.79, 1.79]. However in multivariate analysis of subgroups, PCOS remained significantly associated with higher risk of HDP in non-obese women only [HR: 1.77, 95% CI: 1.11, 2.82]. CONCLUSIONS: Higher risk of HDP in PCOS is likely related to risk factors other than PCOS.

Sexual function, mental health, and quality of life under strain of COVID-19 pandemic in Iranian pregnant and lactating women: a comparative cross-sectional study.

BACKGROUND: The impact of COVID-19 pandemic on mental health of pregnant and lactating women is unclear. This study aimed to assess the impact of COVID-19 on psychological health, sexual function, and quality of life (QoL) in Iranian pregnant and lactating women and compare the results with non-pregnant/non-lactating women. METHOD: This comparative cross-sectional study was carried out on pregnant and lactating women, with non-pregnant/non-lactating women from May to Jun 2020. Patients were asked to complete three questionnaires: Hospital Anxiety and Depression Scale (HADS), Female Sexual Function Index (FSFI), and Short-Form Health Survey (SF-12). One-way ANOVA was used to reveal the statistical differences between the three groups. RESULT: The mean age of patients was 20.81 ± 5.92 years old. The mean (SD) score of HADS in pregnant, lactating and non-pregnant / non-lactating women were 12.11 (6.72), 11.98 (8.44) and 9.38 (6.2) respectively, and the results showed that the scores in pregnant, lactating women were higher than non-pregnant / non-lactating women (P < 0.001). Also the mean (SD) score of QOL and FSFI was 68.29 (9.47), 74.18 (12.65), 79.03 (10.48) and 22.71 (8.16), 22.72 (8.16), 26.19 (3.93) in three groups and the scores in pregnant, lactating women were lower than non-pregnant/non-lactating women (P < 0.001). CONCLUSION: The COVID-19 epidemic increases the risk of depression, anxiety, FSD, and lowers QoL in pregnant and lactating women, with the general population. This suggests the urgent need for psychological intervention in the maternal population during the epidemic.

Metabolic parameters in cord blood of neonate of mothers with obese and non-obese PCOS and controls: retrospective cohort study.

BACKGROUND: Polycystic ovary syndrome (PCOS) is characterized by reproductive disorder and increased risk of metabolic syndrome. This study aimed to assess the metabolic parameters in the cord blood of neonate of mothers with obese PCOS and comparison with non-obese PCOS and controls. METHODS: This retrospective cohort study was conducted in Arash and Kamali Hospital in 2017-2018. The biochemical test was conducted on 78 neonates from obese PCOS mothers, 78 neonates from non-obese PCOS mothers, and 78 neonates from healthy mothers. Finally, cord blood lipid profile and insulin and blood sugar were determined by specific kits. Correlations between variables were compared with chi-square, Mann-Whitney's U, Kruskal-Wallis H tests and regression model by SPSS 23 and P < 0.05 was considered significant. RESULTS: Triglycerides (TG) and high-density lipoprotein cholesterol (HDL) were higher in cord blood of newborn of obese PCOS women than non-obese PCOS and controls (P = 0.02, P < 0.001, respectively). Also, the mean insulin was higher in cord blood of neonate of non-obese PCOS women than in obese PCOS and controls (12.26 ± 12.79 vs. 11.11 ± 16.51 vs. 6.21 ± 10.66, P = 0.01). But in the study, there was no significant difference between the mean of umbilical cord low-density lipoprotein cholesterol (LDL), total cholesterol and blood sugar in three groups. The logistic regression model showed that metabolic parameters were related to PCOS. CONCLUSIONS: In the present study, there was a significant difference between the mean of umbilical cord HDL, cholesterol, and the insulin level in the three groups. But, there was no significant association between the mean of blood sugar, LDL, and TG in the groups. The metabolic disorder in PCOS might affect cord blood lipid and insulin and adulthood health.

Influential factors on quality of life in married Iranian women during the COVID-19 pandemic in 2020: a path analysis.

BACKGROUND: This study aimed to investigate the relationship between quality of life (QoL) with anxiety, depression, corona disease anxiety, sexual function (SF), and marital satisfaction (MS) in married women during the Covid-19 pandemic. METHODS: We performed a cross-sectional study involving n = 296 married women. We used the Short Form Health Survey (SF-12), Marital Satisfaction Scale (MSS), Female Sexual Function Index (FSFI), Hospital Anxiety and Depression Scale, and coronary disease anxiety questionnaire, as determinants of QoL for data collection. Data were analyzed using the Pearson correlation coefficient and path analysis. RESULTS: There was a relationship between the components of QoL with SF, anxiety, depression, MS, general health, and contamination obsessions. The results of path analysis also showed that that SF, MS, anxiety, general health, and corona-related anxiety have a direct effect on women's QoL. General health has a more direct effect on QoL. CONCLUSION: The results of this study could help in a plan to improve the QoL of women during the coronavirus epidemic.

Influential factors on sexual function in infertile women with endometriosis: a path analysis.

BACKGROUND: Endometriosis have a negative influence on women's sexual life. The aim of the current study was to test a conceptual model considering the interrelated role of anxiety, depression, sleep quality, physical activity, BMI, stage of endometriosis, the intensity of dyspareunia and pelvic pain on sexual function (SF) in infertile women with endometriosis. Also test the mediating role of sleep quality, anxiety, and depression. METHOD: In the present cross-sectional study, 220 infertile women with a laparoscopically confirmed endometriosis were recruited. Data were collected using a socio-demographic checklist, Female Sexual Function Index (FSFI), Pittsburgh Sleep Quality Index (PSQI), Hospital Anxiety and Depression Scale (HADS), Visual Analog Scale (VAS). RESULTS: We found that anxiety, depression, sleep quality, BMI, level of education, stage of endometriosis, and dyspareunia have a direct effect on women's SF. In our study, sleep quality, anxiety, pelvic pain, and depression were the four major mediators that the higher scores lead to a decrease in the SF of endometriosis patients. The intensity of pelvic pain with an effect on sleep quality (SQ) and dyspareunia change women's SF. The lower level of physical activity, and higher BMI with indirect effect thorough anxiety, and SQ can worsen SF. Also, a higher level of anxiety leads to poor SQ and depression. Anxiety with both direct and indirect effect impress women's SF. CONCLUSION: It seems that the main risk factors for sexual dysfunction in women with endometriosis are higher rates of anxiety, depression, poor sleep quality, pelvic pain, and dyspareunia. In the care of women with endometriosis, not only laparoscopy and medical treatment should be performed but also psychotherapeutic and psychosexual help should be offered.

Lifestyle and pregnancy complications in polycystic ovary syndrome: The SCOPE cohort study.

OBJECTIVES: To investigate the risk of pregnancy complications in women with and without polycystic ovary syndrome after consideration of lifestyle factors. DESIGN: Prospective cohort. PATIENTS AND MEASUREMENTS: Participants (n = 5628) were apparently healthy nulliparous women with singleton pregnancies from the Screening for Pregnancy Endpoints study in New Zealand, Australia, United Kingdom and Ireland. Multivariable regression models were performed assessing the association of self-reported polycystic ovary syndrome status with pregnancy complications with consideration of lifestyle factors at the 15th week of gestation. RESULTS: Women with polycystic ovary syndrome (n = 354) were older, had a higher socio-economic index and body mass index and were less likely to consume alcohol and smoke but more likely to do vigorous exercise and take multivitamins. In univariable analysis, polycystic ovary syndrome was associated with increased risk of gestational diabetes (OR: 2.2, 95% CI: 1.2, 4.0). In multivariable models, polycystic ovary syndrome was only significantly associated with decreased risk of large for gestational age (OR: 0.62, 95% CI: 0.40, 0.98) with a population attributable risk of 0.22%. None of the other outcomes were attributable to polycystic ovary syndrome status. CONCLUSIONS: Polycystic ovary syndrome is associated with a lower risk of large for gestational age infants. In this low-risk population, the risk of pregnancy complications was not increased in women with polycystic ovary syndrome who were following a healthy lifestyle. Further studies are warranted assessing the contribution of lifestyle factors to the risk of pregnancy complications in higher risk groups of women with and without polycystic ovary syndrome.

Polycystic ovary syndrome and adverse pregnancy outcomes: Current state of knowledge, challenges and potential implications for practice.

Although there is a growing body of literature reporting that pregnancies in women with polycystic ovary syndrome (PCOS) are associated with greater complications than those without PCOS, methodological differences across studies make these results difficult to consolidate. This narrative review outlines potential mechanisms involved in adverse pregnancy outcomes in PCOS and the nature of the complications. It covers limitations of current evidence and future research directions. Future research should include prospective studies with phenotypic stratification of PCOS and matching or consideration of specific PCOS manifestations and risk factors specific to each pregnancy complication. This review also emphasizes the importance of following a healthy lifestyle for women with PCOS and of individualized care according to overall risk factors for pregnancy complications.

A Comparison of Sexual Function in Women with Polycystic Ovary Syndrome (PCOS) Whose Mothers Had PCOS During Their Pregnancy Period with Those Without PCOS.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women during reproductive ages. Clinical symptoms associated with PCOS, such as hirsutism, acne, alopecia, obesity, and infertility, may lead to emotional morbidity and then impaired sexual function in those affected. During intrauterine development, the fetus may program the development of diseases during adulthood. In this study, we aimed to examine sexual function in women with PCOS, exposed to maternal androgen excess during their prenatal life compared to non-exposed PCOS patients. In this cross-sectional study, 768 married women with PCOS, aged 18-49 years, were subdivided into two groups, based on their mothers' PCOS status: women whose mothers had PCOS (N = 94) and women whose mothers did not have PCOS (N = 674). Data were collected using a questionnaire including information on demographics, anthropometric and reproductive characteristics, and the Female Sexual Function Index. Blood serum samples were collected from patients for assessment of total testosterone and sex hormone-binding globulin levels. Results revealed that sexual dysfunction was significantly higher in PCOS women whose mothers also had PCOS, compared to those whose mothers did not (38.6 vs. 25.3%, p = .01). After adjusting for confounding variables, logistic regression analysis showed that odds ratios for sexual dysfunction (total) and sexual dysfunction in the pain domain were significantly higher in the exposed PCOS women versus the non-exposed women (OR 1.81, 95% CI 1.06-3.07, p = .02 and 1.68, 95% CI 1.01-2.77, p = .04, respectively). Our study demonstrates increased sexual dysfunction in PCOS women whose mothers also had PCOS.

Insulin resistance in obesity and polycystic ovary syndrome: systematic review and meta-analysis of observational studies.

We aimed at investigating whether insulin resistance (IR)/sensitivity are impaired in obese/non-obese polycystic ovary syndrome (PCOS) and obese/non-obese healthy controls. A comprehensive literature search was performed for observational, English language studies. Meta-analysis was performed with the random effects model according to the heterogeneity. Eligible studies, involving 3037 women in four groups of: 1-obese, PCOS; 2-non-obese, PCOS, 3-obese, non-PCOS and 4-Non-obese, non-PCOS were included. Based on the insulin resistance index (HOMA-IR) analysis, the pooled mean (95% Conf. Interval) of HOMA IR in groups 1-4 were 4.38 (3.84, 4.92), 2.68 (2.16, 3.20), 2.44 (2.06, 2.82) and 1.34 (1.06, 1.63), respectively. Meta-analysis showed that group 1 (obese, PCOS patients) statistically have the highest IR and group 4 (non-obese, non-PCOS women) have the highest insulin sensitivity. Group 2 (non-obese, PCOS patients) and group 3 (obese, non-PCOS women) were between this range and they had lower IR than group 1 (obese, PCOS) and lower insulin sensitivity than group 4 (non-obese, non-PCOS). So, there were statistical differences between all groups except between groups 2 and 3. Insulin sensitivity indexes (quickie and ISI), also confirm the IR index (HOMA-IR) results. Based on different IR/sensitivity indexes, we found no evidence of any different effects of BMI ≥ 30 kg/m(2) on IR/sensitivity. In conclusion, PCOS status intensifies the adverse effects of obesity on IR, it has to be appropriately addressed in primary and secondary preventive cares and treatments provided for these women.

Association of PCOS and its clinical signs with sexual function among Iranian women affected by PCOS.

INTRODUCTION: Polycystic ovary syndrome (PCOS) and its physiological and psychological changes influence the sexual function of women affected. AIM: In the present study, we aimed to investigate the association of PCOS and its clinical signs with sexual function among a population of married Iranian women affected by PCOS. MAIN OUTCOME MEASURE: The impact of clinical signs of PCOS on sexual function of affected women was the main outcome measure in the present study. METHODS: This cross-sectional study was carried out on 591 married women with PCOS, aged 18-45 years. Data were collected using a questionnaire including information on demographic and reproductive status and the Female Sexual Function Index. Data were analyzed using chi-square test, Mann-Whitney test, and logistic regression analysis. RESULTS: The participants' mean age was 30.6 years. Among associated manifestations of PCOS, infertility and hair loss have significant adverse effects on female sexual function. Logistic regression analysis showed that PCOS women with infertility have a significantly lower sexual function score compared with those who are fertile. Subgroup analysis demonstrated that compared with their fertile counterparts, PCOS women with infertility had significant sexual dysfunction in all aspects except desire and pain. CONCLUSION: Among various manifestations of PCOS, infertility mainly disrupts the sexual function of affected women.

The effects of lifestyle and behavioural interventions on cancer recurrence, overall survival and quality of life in breast cancer survivors: A systematic review and network meta-analysis.

Lifestyle/behavioural interventions may improve breast cancer outcomes and quality of life (QoL); however, uncertainty remains about the most effective interventions due to limited evidence. This study aimed to assess and compare the effects of lifestyle/behavioural interventions on cancer recurrence, survival and QoL in breast cancer survivors. Electronic databases including Medline, EMBASE, PsycINFO, CINAHL and EBM Reviews were searched for relevant literature. Randomized controlled trials (RCTs) and quasi-RCTs comparing a lifestyle/behavioural intervention with a control condition in breast cancer survivors were included. Outcomes included cancer recurrence, overall survival and QoL. A network meta-analysis synthesized intervention effect. Studies not included in the analysis were reported narratively. Of 6251 identified articles, 38 studies met the selection criteria. Limited evidence exists on the impacts of lifestyle/behavioural interventions on breast cancer recurrence/survival. Exercise was identified as the most effective intervention in improving overall survival (HR 0.50, 95 % CI 0.36, 0.68). Lifestyle/behavioural interventions may improve QoL; psychosocial interventions (SMD 1.28, 95 % CI 0.80, 1.77) and aerobic-resistance exercise (SMD 0.33, 95 % CI -0.03, 0.69) were the most effective interventions to enhance QoL. This review highlights potential post-breast cancer benefits from lifestyle/behavioural interventions, notably exercise and psychosocial support for QoL and exercise for overall survival. Thus, encouraging active lifestyle, stress management and coping skills programs during and after cancer treatment may enhance physical wellbeing and QoL. However, the findings should be interpreted with caution due to the small number and sample sizes of studies. Future longer-term RCTs are required for conclusive recommendations.

Key Components of Antenatal Lifestyle Interventions to Optimize Gestational Weight Gain: Secondary Analysis of a Systematic Review.

Importance: Randomized clinical trials have found that antenatal lifestyle interventions optimize gestational weight gain (GWG) and pregnancy outcomes. However, key components of successful interventions for implementation have not been systematically identified. Objective: To evaluate intervention components using the Template for Intervention Description and Replication (TIDieR) framework to inform implementation of antenatal lifestyle interventions in routine antenatal care. Data Sources: Included studies were drawn from a recently published systematic review on the efficacy of antenatal lifestyle interventions for optimizing GWG. The Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Health Technology Assessment Database, MEDLINE, and Embase were searched from January 1990 to May 2020. Study Selection: Randomized clinical trials examining efficacy of antenatal lifestyle interventions in optimizing GWG were included. Data Extraction and Synthesis: Random effects meta-analyses were used to evaluate the association of intervention characteristics with efficacy of antenatal lifestyle interventions in optimizing GWG. The results are reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline. Data extraction was performed by 2 independent reviewers. Main Outcomes and Measures: The main outcome was mean GWG. Measures included characteristics of antenatal lifestyle interventions comprising domains related to theoretical framework, material, procedure, facilitator (allied health staff, medical staff, or researcher), delivery format (individual or group), mode, location, gestational age at commencement (<20 wk or ≥20 wk), number of sessions (low [1-5 sessions], moderate [6-20 sessions], and high [≥21 sessions]), duration (low [1-12 wk], moderate [13-20 wk], and high [≥21 wk]), tailoring, attrition, and adherence. For all mean differences (MDs), the reference group was the control group (ie, usual care). Results: Overall, 99 studies with 34 546 pregnant individuals were included with differential effective intervention components found according to intervention type. Broadly, interventions delivered by an allied health professional were associated with a greater decrease in GWG compared with those delivered by other facilitators (MD, -1.36 kg; 95% CI, -1.71 to -1.02 kg; P < .001). Compared with corresponding subgroups, dietary interventions with an individual delivery format (MD, -3.91 kg; 95% CI -5.82 to -2.01 kg; P = .002) and moderate number of sessions (MD, -4.35 kg; 95% CI -5.80 to -2.89 kg; P < .001) were associated with the greatest decrease in GWG. Physical activity and mixed behavioral interventions had attenuated associations with GWG. These interventions may benefit from an earlier commencement and a longer duration for more effective optimization of GWG. Conclusions and Relevance: These findings suggest that pragmatic research may be needed to test and evaluate effective intervention components to inform implementation of interventions in routine antenatal care for broad public health benefit.

Breaking Boundaries: Toward Consistent Gender-Sensitive Language in Sexual and Reproductive Health Guidelines.

This review assesses gender-sensitive language in sexual and reproductive health (SRH) guidelines, including a guideline for polycystic ovary syndrome. We conducted a systematic search across databases like Medline, EMBASE, and Cochrane until July 31, 2023, using terms related to gender-inclusivity, SRH, and guideline protocols. Criteria for inclusion were gender-sensitive language, SRH focus, and guideline relevance, excluding non-English articles or those without policy considerations. Our search yielded 25 studies, with 6 included for qualitative synthesis. Results showed significant gaps in using gender-sensitive language in SRH guidelines. The debate on this language mirrors broader societal discourse. Recognizing gender diversity is essential for research, clinical practices, and societal norms. While promoting inclusion, drawbacks like unintended erasure or miscommunication should also be addressed. A gender-additive approach balances inclusivity and biological accuracy. Precise and inclusive discourse is crucial. Future research should focus on systemic approaches in the SRH sector.

Implementation of Antenatal Lifestyle Interventions Into Routine Care: Secondary Analysis of a Systematic Review.

Importance: Lifestyle interventions in pregnancy optimize gestational weight gain and improve pregnancy outcomes, with implementation recommended by the US Preventive Services Task Force. Yet, implementation research taking these efficacy trials into pragmatic translation remains limited. Objective: To evaluate success factors for implementing pregnancy lifestyle interventions into antenatal care settings in a meta-analysis, using the penetration, implementation, participation, and effectiveness (PIPE) impact metric. Data Sources: Data from a previous systematic review that searched across 9 databases, including MEDLINE, Embase, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, and Health Technology Assessment Database, were obtained, in 2 stages, up to May 6, 2020. Study Selection: Randomized clinical trials reporting gestational weight gain in singleton pregnancies. Data Extraction and Synthesis: The association of penetration, implementation, and participation with effectiveness of antenatal lifestyle interventions in optimizing gestational weight gain was estimated using random-effects meta-analyses. The Cochrane risk of bias tool, version 1.0, was used to assess risk of bias. Main Outcomes and Measures: Penetration (reach), implementation (fidelity), participation, and effectiveness of randomized clinical trials of lifestyle interventions in pregnancy. Results: Ninety-nine studies with 34 546 participants were included. Only 14 studies reported penetration of target populations. Overall, 38 studies (38.4%) had moderate fidelity, 25 (25.2%) had high fidelity, and 36 (36.4%) had unclear fidelity. Participation was reported in 84 studies (84.8%). Lifestyle interventions were associated with reducing gestational weight gain by 1.15 kg (95% CI, -1.40 to -0.91 kg). Conclusions and Relevance: The findings of this systematic review and meta-analysis suggest that, despite the large body of evidence on efficacy of lifestyle interventions during pregnancy in optimizing gestational weight gain, little guidance is available to inform implementation of this evidence into practice. There is a need to better elucidate implementation outcomes in trial design alongside pragmatic implementation research to improve the health of women who are pregnant and the next generation.

Ethnic differences in response to lifestyle intervention for the prevention of type 2 diabetes in adults: A systematic review and meta-analysis.

The risk of type 2 diabetes mellitus (T2DM) varies by ethnicity, but ethnic differences in response to diabetes prevention interventions remain unclear. This systematic review and meta-analysis assessed ethnic differences in the effects of lifestyle interventions on T2DM incidence, glycemic outcomes (fasting glucose, 2-h glucose, HbA1c ), anthropometric measures (weight, BMI, waist circumference), and lifestyle behaviors (physical activity, energy intake, energy from fat, fiber intake). MEDLINE, EMBASE, and other databases were searched (to June 15, 2020) for randomized and non-randomized controlled trials on lifestyle interventions (diet and/or physical activity) in adults at risk of T2DM. Ethnicity was categorized into European, South Asian, East and Southeast Asian, Middle Eastern, Latin American, and African groups. Forty-four studies were included in meta-analyses. Overall, lifestyle interventions resulted in significant improvement in T2DM incidence, glycemic outcomes, anthropometric measures, physical activity, and energy intake (all P < 0.01). Significant subgroup differences by ethnicity were found for 2-h glucose, weight, BMI, and waist circumference (all P < 0.05) but not for T2DM incidence, fasting glucose, HbA1c , and physical activity (all P > 0.05). Few studies in non-European groups reported dietary intake. Lifestyle interventions in different ethnic groups may have similar effects in reducing incidence of T2DM although this needs to be confirmed in further studies.

Association of Antenatal Diet and Physical Activity-Based Interventions With Gestational Weight Gain and Pregnancy Outcomes: A Systematic Review and Meta-analysis.

IMPORTANCE: Excessive gestational weight gain (GWG) is common and associated with adverse pregnancy outcomes. Antenatal lifestyle interventions limit GWG; yet benefits of different intervention types and specific maternal and neonatal outcomes are unclear. OBJECTIVE: To evaluate the association of different types of diet and physical activity-based antenatal lifestyle interventions with GWG and maternal and neonatal outcomes. DATA SOURCES: A 2-stage systematic literature search of MEDLINE, Embase, Cochrane Database of Systematic Reviews, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, and Health Technology Assessment Database was conducted from February 1, 2017, to May 31, 2020. Search results from the present study were integrated with those from a previous systematic review from 1990 to February 2017. STUDY SELECTION: Randomized trials reporting GWG and maternal and neonatal outcomes. DATA EXTRACTION AND SYNTHESIS: Data were extracted for random-effects meta-analyses to calculate the summary effect estimates and 95% CIs. MAIN OUTCOMES AND MEASURES: Outcomes were clinically prioritized, with mean GWG as the primary outcome. Secondary outcomes included gestational diabetes, hypertensive disorders of pregnancy, cesarean section, preterm delivery, large or small for gestational age neonates, neonatal intensive care unit admission, or fetal death. RESULTS: A total of 117 randomized clinical trials of antenatal lifestyle interventions (involving 34 546 women) were included. Overall lifestyle intervention was associated with reduced GWG (-1.15 kg; 95% CI, -1.40 to -0.91), risk of gestational diabetes (odds ratio [OR], 0.79; 95% CI, 0.70-0.89), and total adverse maternal outcomes (OR, 0.89; 95% CI, 0.84-0.94) vs routine care. Compared with routine care, diet was associated with less GWG (-2.63 kg; 95% CI, -3.87 to -1.40) than physical activity (-1.04 kg; 95% CI, -1.33 to -0.74) or mixed interventions (eg, unstructured lifestyle support, written information with weight monitoring, or behavioral support alone) (-0.74 kg; 95% CI, -1.06 to -0.43). Diet was associated with reduced risk of gestational diabetes (OR, 0.61; 95% CI, 0.45-0.82), preterm delivery (OR, 0.43; 95% CI, 0.22-0.84), large for gestational age neonate (OR, 0.19; 95% CI, 0.08-0.47), neonatal intensive care admission (OR, 0.68; 95% CI, 0.48-0.95), and total adverse maternal (OR, 0.75; 95% CI, 0.61-0.92) and neonatal outcomes (OR, 0.44; 95% CI, 0.26-0.72). Physical activity was associated with reduced GWG and reduced risk of gestational diabetes (OR, 0.60; 95% CI, 0.47-0.75), hypertensive disorders (OR, 0.66; 95% CI, 0.48-0.90), cesarean section (OR, 0.85; 95% CI, 0.75-0.95), and total adverse maternal outcomes (OR, 0.78; 95% CI, 0.71-0.86). Diet with physical activity was associated with reduced GWG (-1.35 kg; 95% CI, -1.95 to -0.75) and reduced risk of gestational diabetes (OR, 0.72; 95% CI, 0.54-0.96) and total adverse maternal outcomes (OR, 0.81; 95% CI, 0.69-0.95). Mixed interventions were associated with reduced GWG only. CONCLUSIONS AND RELEVANCE: This systematic review and meta-analysis found level 1 evidence that antenatal structured diet and physical activity-based lifestyle interventions were associated with reduced GWG and lower risk of adverse maternal and neonatal outcomes. The findings support the implementation of such interventions in routine antenatal care and policy around the world.

The role of midwives and obstetrical nurses in the promotion of healthy lifestyle during pregnancy.

Women with maternal obesity, an unhealthy lifestyle before and during pregnancy and excess gestational weight gain have an increased risk of adverse pregnancy and birth outcomes that can also increase the risk of long-term poor health for them and their children. Pregnant women have frequent medical appointments and are highly receptive to health advice. Healthcare professionals who interact with women during pregnancy are in a privileged position to support women to make lasting healthy lifestyle changes that can improve gestational weight gain and pregnancy outcomes and halt the intergenerational nature of obesity. Midwives and obstetrical nurses are key healthcare professionals responsible for providing antenatal care in most countries. Therefore, it is crucial for them to build and enhance their ability to promote healthy lifestyles in pregnant women. Undergraduate midwifery curricula usually lack sufficient lifestyle content to provide emerging midwives and obstetrical nurses with the knowledge, skills, and confidence to effectively assess and support healthy lifestyle behaviours in pregnant women. Consequently, registered midwives and obstetrical nurses may not recognise their role in healthy lifestyle promotion specific to healthy eating and physical activity in practice. In addition, practising midwives and obstetrical nurses do not consistently have access to healthy lifestyle promotion training in the workplace. Therefore, many midwives and obstetrical nurses may not have the confidence and/or skills to support pregnant women to improve their lifestyles. This narrative review summarises the role of midwives and obstetrical nurses in the promotion of healthy lifestyles relating to healthy eating and physical activity and optimising weight in pregnancy, the barriers that they face to deliver optimal care and an overview of what we know works when supporting midwives and obstetrical nurses in their role to support women in achieving a healthy lifestyle.

A review of maternal overweight and obesity and its impact on cardiometabolic outcomes during pregnancy and postpartum.

The rates of maternal overweight and obesity, but also excess gestational weight gain, are increasing. Pregnancy complications, including gestational diabetes mellitus, gestational hypertension, pre-eclampsia and delivery of a preterm or growth restricted baby, are higher for both women with overweight and obesity and women who gain excess weight during their pregnancy. Other conditions such as polycystic ovary syndrome are also strongly linked to overweight and obesity and worsened pregnancy complications. All of these conditions place women at increased risk for future cardiometabolic diseases. If overweight and obesity, but also excess gestational weight gain, can be reduced in women of reproductive age, then multiple comorbidities associated with pregnancy complications may also be reduced in the years after childbirth. This narrative review highlights the association between maternal overweight and obesity and gestational weight gain, with gestational diabetes, pre-eclampsia, polycystic ovary syndrome and delivery of a preterm or growth restricted baby. This review also addresses how these adverse conditions are linked to cardiometabolic diseases after birth. We report that while the independent associations between obesity and gestational weight gain are evident across many of the adverse conditions assessed, whether body mass index or gestational weight gain is a stronger driving factor for many of these is currently unclear. Mechanisms linking gestational diabetes mellitus, gestational hypertension, pre-eclampsia, preterm delivery and polycystic ovary syndrome to heightened risk for cardiometabolic diseases are multifactorial but relate to cardiovascular and inflammatory pathways that are also found in overweight and obesity. The need for post-partum cardiovascular risk assessment and follow-up care remains overlooked. Such early detection and intervention for women with pregnancy-related complications will significantly attenuate risk for cardiovascular disease.
