Optimising mothers' health behaviour after hypertensive disorders of pregnancy: a qualitative study of a postnatal intervention

The women's cardiovascular disease risk perception after hypertensive disorders of pregnancy: A qualitative meta-synthesis

BACKGROUND

Hypertensive disorders of pregnancy is associated with increased risk of cardiovascular disease later in life, but studies suggest that women with previous hypertensive disorders of pregnancy are not aware of this. Little is known about how these women perceive the condition and the associated long-term risks.

OBJECTIVES

This study aims to examine and synthesize qualitative evidence on the perceptions and awareness of women with hypertensive disorders of pregnancy following perceived cardiovascular disease risk.

METHODS

Computer searches of Pub Med, Embase, Web of Science, Cochrane Library, CINAHL, CNKI, Wanfang database, Vip and SinoMed for all qualitative studies that met the inclusion criteria. The time frame for the search was from the establishment of the database to April 2024. Literature quality was assessed using the Australian Joanna Briggs Institute Centre for Evidence-Based Health Care Qualitative Research quality assessment criteria, and results were summarised and integrated using a pooled integration approach.

RESULTS

Eleven studies that fulfilled the inclusion criteria and quality assessment were included in the meta synthesis. Three themes were identified during the analysis: (1)Factors affecting perceived cardiovascular risk in women with hypertensive disorders of pregnancy; (2)Women with hypertensive disorders of pregnancy use different strategies to cope with cardiovascular risk; (3)Needs and expectations for coping with cardiovascular disease risk.

CONCLUSIONS

Both women with hypertensive disorders of pregnancy and healthcare providers lack knowledge of the link between hypertensive disorders of pregnancy and cardiovascular risk. Healthcare professionals should establish a multidimensional support model, pay timely attention to postpartum women's psycho-emotional and risk awareness, and give individualised health education to promote health behaviour change. At the same time, professionals should be given standardised training and personalised follow-up services to reduce the incidence of cardiovascular disease in the future.

Effect of Comprehensive Educational Program on Preeclamptic Women's Risk Perception of Cardiovascular Disease, Self-Efficacy, and Adherence to Healthy Lifestyle Behaviors

PURPOSE

To evaluate the effect of a comprehensive educational program on preeclamptic women's knowledge, risk perception of cardiovascular disease, self-efficacy, and adherence to healthy lifestyle behaviors.

PATIENTS AND METHODS

This study employed a pretest-posttest design. One hundred and two women who previously had preeclampsia were enrolled from July 2022 to December 2022 from outpatient obstetrics, gynecology, and family planning clinics. The primary and secondary outcomes were measured at baseline, after eight weeks, and after three months of the educational intervention. The data were analyzed using SPSS version 23, descriptive and inferential statistics, specifically the Chi-square test, independent t-tests, and repeated measures ANOVA.

RESULTS

A statistically significant difference was found between the two groups immediately post-intervention and the three-month follow-up, with a significant improvement among the intervention group than control group regarding cardiovascular disease knowledge (p < 0.001), risk perception (p < 0.001), self-efficacy (p < 0.001), and healthy lifestyle behaviors (p < 0.001). There was a statistically significant interaction between group and time regarding total cardiovascular disease risk perception (F = 203.67, p < 0.001, η2 = 0.673), self-efficacy (F = 70.06, p < 0.001, η2 = 0.405), and adherence to healthy lifestyle behaviors (F = 145.08, p < 0.001, η2 = 0.597).

CONCLUSION

This study concluded that the comprehensive educational program had a positive effect on improving preeclamptic women's knowledge and risk perception of CVD, self-efficacy, and adherence to healthy lifestyle behaviors following preeclampsia.

Hypertensive Disorders of Pregnancy: Innovative Management Strategies

Hypertensive disorders of pregnancy (HDP) complicate 13% to 15% of pregnancies in the United States. Historically marginalized communities are at increased risk, with preeclampsia and eclampsia being the leading cause of death in this population. Pregnant individuals with HDP require more frequent and intensive monitoring throughout the antepartum period outside of routine standard of care prenatal visits. Additionally, acute rises in blood pressure often occur 3 to 6 days postpartum and are challenging to identify and treat, as most postpartum individuals are usually scheduled for their first visit 6 weeks after delivery. Thus, a multifaceted approach is necessary to improve recognition and treatment of HDP throughout the peripartum course. There are limited studies investigating interventions for the management of HDP, especially within the United States, where maternal mortality is rising, and in higher-risk groups. We review the state of current management of HDP and innovative strategies such as blood pressure self-monitoring, telemedicine, and community health worker intervention.

Pregnancy-associated cardiovascular risks and postpartum care; an opportunity for interventions aiming at health preservation and disease prevention

Cardiovascular disease (CVD) is the leading cause of premature death and disability for female individuals around the world and the rates are increasing in those aged 35-44 years. Certain pregnancy complications (Pregnancy-associated Cardiovascular Risks (P-CVR))are linked to an increased risk of future CVD making pregnancy and the postpartum period as an ideal time to screen individuals for underlying, often unrecognized, cardiovascular risk factors. Pregnancy complications associated with an increased risk of future CVD including the hypertensive disorders of pregnancy, gestational diabetes, idiopathic preterm birth, delivery of a growth restricted baby and a placental abruption that leads to delivery. A number of guidelines and research groups recommend postpartum CVR screening, counseling and lifestyle intervention for all those who have had one or more of P-CVRs starting within the first six months postpartum. An individualized plan for postpartum screening should be created with the individual and lifestyle interventions discussed.

A life-course approach to tackling noncommunicable diseases in women

Women's health has been critically underserved by a failure to look beyond women's sexual and reproductive systems to adequately consider their broader health needs. In almost every country in the world, noncommunicable diseases are the leading causes of death for women. Among these, cardiovascular disease (including heart disease and stroke) and cancer are the major causes of mortality. Risks for these conditions exist at each stage of women's lives, but recognition of the unique needs of women for the prevention and management of noncommunicable diseases is relatively recent and still emerging. Once they are diagnosed, treatments for these diseases are often costly and noncurative. Therefore, we call for a strategic, innovative life-course approach to identifying disease triggers and instigating cost-effective measures to minimize exposure in a timely manner. Prohibitive barriers to implementing this holistic approach to women's health exist in both the social arena and the medical arena. Recognizing these impediments and implementing practical approaches to surmounting them is a rational approach to advancing health equity for women, with ultimate benefits for society as a whole.

Aspirin for the Prevention of Early and Severe Pre-Eclampsia Recurrence: A Real-World Population-Based Study

BACKGROUND

Many clinical trials have reported that low-dose aspirin decreases the risk of pre-eclampsia in women with prior pre-eclampsia. However, its impact in a real-world population has not been fully assessed.

OBJECTIVES

To assess the rates of low-dose aspirin initiation during pregnancy in women with a history of pre-eclampsia, and to evaluate the impact of low-dose aspirin in prevention of pre-eclampsia recurrence in a real-world population.

STUDY DESIGN

CONCEPTION is a French nationwide cohort study which uses data from the country's National Health Data System database. We included all women in France who gave birth at least twice between 2010-2018, and who had pre-eclampsia during their first pregnancy. Every dispensing of low-dose aspirin (75-300 mg) between the beginning of their second pregnancy and 36 weeks of gestation (WG) was identified. We used Poisson regression models to estimate the adjusted incidence rate ratios (aIRRs) of receiving aspirin at least once during their second pregnancy. In women who had early and/or severe pre-eclampsia during their first pregnancy, we estimated the IRRs of pre-eclampsia recurrence during their second pregnancy according to the aspirin therapy.

RESULTS

In 28,467 women who were included in the study, the aspirin initiation rate during the second pregnancy ranged from 27.8% for women in whose first pregnancy the pre-eclampsia was mild and late, to 79.9% for those women whose pre-eclampsia was severe and early. Just over half (54.3%) of those treated with aspirin-initiated treatment before 16 WG and adhered to treatment. Compared with women with mild and late pre-eclampsia, the aIRRs (95% CI) for receiving aspirin at least once during the second pregnancy were 1.94 (1.86-2.03) for women with severe and late pre-eclampsia, 2.34 (2.17-2.52) for those with early and mild pre-eclampsia, and 2.87 [2.74-3.01] for those with early and severe pre-eclampsia E. Social deprivation was associated with a lower initiation of aspirin (IRR = 0.74 [0.70-0.78]). Aspirin was not associated with a lower risk of mild and late pre-eclampsia, severe and late pre-eclampsia, or mild and early pre-eclampsia during the second pregnancy. The aIRRs for severe and early pre-eclampsia during the second pregnancy were 0.77 (0.62-0.95) for women who received prescribed aspirin at least once, 0.71 (0.5-0.89) for those who initiated aspirin therapy before 16 WG, and 0.60 (0.47-0.77) for those who adhered to aspirin treatment throughout their second pregnancy. The risk of severe and early pre-eclampsia was lower only when the prescribed mean daily dose was ≥ 100 mg/day.

CONCLUSION

In women with a history of pre-eclampsia, aspirin initiation during a second pregnancy and adherence to the prescribed dosage were largely insufficient, especially for women experiencing social deprivation. Aspirin initiated before 16 WG at a dose ≥ 100 mg/day was associated with a lower risk of severe and early pre-eclampsia.

Patients' understanding of long-term cardiovascular risks and associated health-seeking behaviours after pre-eclampsia

OBJECTIVE

The lifelong risks of cardiovascular disease following hypertensive disorders of pregnancy are well described. Awareness of these risks and associated health-seeking behaviours among affected individuals remains unclear. We aimed to assess participants' knowledge of their cardiovascular disease risk and relevant health-seeking behaviours following a pregnancy affected by preeclampsia or gestational hypertension.

METHODS

We undertook a single-site, cross-sectional cohort study. The target population included individuals who birthed at a large tertiary referral centre in Melbourne, Australia, between 2016 and 2020, and were diagnosed with gestational hypertension or pre-eclampsia. Participants completed a survey assessing pregnancy details, medical comorbidities, knowledge of future risks and health-seeking behaviours post-pregnancy.

RESULTS

1526 individuals met inclusion criteria and 438 (28.6%) completed the survey. Of these, 62.6% (n=237) were unaware of their increased risk of cardiovascular disease following a hypertensive disorder of pregnancy. Participants who reported awareness of their increased risk were more likely to have annual blood pressure monitoring (54.6% vs 38.1%, p<0.01), and at least one assessment of blood cholesterol (p<0.01), blood glucose (p=0.03) and renal function (p=0.01). Participants who were aware were more likely to be taking antihypertensive medication (24.5% vs 6.6%, p<0.01) since pregnancy, compared with those who were unaware. There were no differences between groups in diet, exercise or smoking habits.

CONCLUSION

Among our study cohort, risk awareness was associated with increased health-seeking behaviours. Participants who were aware of their increased risk of cardiovascular disease were more likely to have regular cardiovascular risk factor assessments. They were also more likely to be taking antihypertensive medication.

COVID-19, lifestyle behaviors and mental health: A mixed methods study of women 6 months following a hypertensive pregnancy

Introduction

The COVID-19 pandemic introduced unprecedented challenges to both the physical and psychological health of postpartum women. The aim of this study was to determine how the COVID-19 pandemic affected the diet, physical activity and mental health of women 6 months following a hypertensive disorder of pregnancy.

Methods

Mixed methods sub-study of the Blood Pressure Postpartum trial, which recruited women following a hypertensive disorder of pregnancy from six Sydney metropolitan hospitals. Cross sectional analysis of baseline quantitative data, collected at 6-months postpartum from March 2019-February 2022, and qualitative data analysis from semi-structured telephone interviews, was performed. Dates of COVID-19 lockdowns for Sydney, Australia were collected from government websites. Diet (vegetable, fruit, alcohol, take away intake) and physical activity (walking, vigorous activity, strength training frequency and duration) were assessed using the self-report NSW Population Health Survey. Depression and anxiety were assessed using the Edinburgh Depression Scale and GAD-7 scale, respectively. Outcome data were compared between women who completed surveys "In Lockdown" vs. "Not in Lockdown" as well as "Prior to any Lockdown" vs. "During or Following any Lockdown".

Results

Of 506 participants, 84 women completed the study surveys "In Lockdown," and 149 completed the surveys "Prior to any Lockdown." Thirty-four participants were interviewed. There were no statistically significant differences in diet, physical activity, depression and anxiety among women who completed the survey "In Lockdown" vs. "Not in Lockdown." "Prior to any Lockdown," participants were more likely to do any walking (95% vs. 89%, p = 0.017), any vigorous activity (43% vs. 30%, p = 0.006) or any strength training (44% vs. 33%, p = 0.024), spent more time doing vigorous activity (p = 0.003) and strength training (p = 0.047) and were more likely to drink alcohol at least monthly (54% vs. 38%, p < 0.001) compared with "During or Following any Lockdown."

Conclusions

Our findings suggest that the confinements of lockdown did not markedly influence the mental health, diet and physical activity behaviors of women 6 months following hypertensive pregnancy. However, physical activity levels were reduced following the emergence of COVID-19, suggesting targeted efforts may be necessary to re-engage postpartum women with exercise.
