The relationship of hyperemesis gravidarum with sleep disorders, anxiety and depression

State-trait anxiety levels and vital signs of pregnant women following intervention with virtual reality during the nonstress test: A randomized controlled trial

BACKGROUND

Pregnant women often experience anxiety due to pregnancy, negatively impacting their and their fetus' health. Non-pharmacological interventions, such as virtual reality (VR), could reduce anxiety levels, potentially impacting non-stress tests or the physiological responses of the pregnant woman and the fetus.

METHODS

A randomized clinical trial conducted between February and December 2022 involved 286 term pregnant women. They were divided into a VR intervention group (146 women) and a control group (140 women). The intervention consisted of 20 min of 3D glasses with images and sounds during a third-trimester nonstress test. Anxiety was measured using the Spielberg State-Trait Anxiety Inventory (STAI), alongside physiological parameters.

RESULTS

The VR group exhibited lower anxiety levels compared to controls (STAI score: Rosenthal's r: -0.54, p = 0.01; state anxiety: Rosenthal's r: -0.40, p = 0.001; trait anxiety: Rosenthal's r: -0.41, p = 0.001). Within the VR group, there was a significant reduction in trait anxiety (Rosenthal's r, 1.27; p < 0.001) and total anxiety (Rosenthal's r, 1.63; p < 0.001) post-intervention, along with decreased systolic blood pressure (p < 0.001), diastolic blood pressure (p < 0.001), and maternal heart rate (p = 0.02).

LIMITATIONS

Future research could explore additional pregnancy-related variables, such as postpartum anxiety.

CONCLUSIONS

The results confirm that the use of VR is beneficial for pregnant women and their fetuses, as it decreases anxiety levels, and improves physiological parameters such as blood pressure and maternal heart rate during the nonstress test. VR is a technique that is easy to integrate into the healthcare system due to its non-invasive and non-pharmacological nature.

[Hyperemesis Gravidarum - an Interprofessional and Interdisciplinary Challenge - Evidence-Based Review]

Hyperemesis gravidarum (HG) is a multifactorial disease characterized by severe and persisting nausea and vomiting, impairment of oral intake, weight loss of at least 5%, electrolyte abnormalities, and dehydration. The prevalence of HG ranges from 0.3 to 10% worldwide. The diagnosis is made by the patient's prehistory, clinical symptoms, physical examination, and the typical laboratory abnormalities. Therapeutic cornerstones are nutrition advice, consultation of life style, psychological/psychosocial support of the mother as well as the administration of antiemetics in a stepwise approach, depending on the severity of symptoms, and finally admission to hospital in severe cases. Treatment of patients requires close interprofessional and interdisciplinary cooperation.

Women's experiences of Hyperemesis Gravidarum (HG) and of attending a dedicated multi-disciplinary hydration clinic

PROBLEM

Hyperemesis Gravidarum (HG) is a severe form of nausea and vomiting in pregnancy that affects 1-3 % of women and has profound nutritional, physical and psychological consequences. Previous research identified that women with HG report inadequate infrastructure for day case management.

INTRODUCTION

A multi-disciplinary HG day case service (IRIS Hydration Clinic) was launched and provides routine care for women with HG in a dedicated unit. The multi-disciplinary team involves midwives, dietitians, obstetricians and perinatal mental health.

AIMS

To explore women's experiences of HG and of attending the dedicated clinic.

METHODS

Ten interviews were conducted with women who attended the clinic. Data were transcribed and analysed using Reflexive Thematic Analysis.

FINDINGS

The physical and psychological impact of HG was captured. The appreciation for the dedicated clinic was a common theme, regarding having somewhere specific for treatment rather than ad-hoc treatment. 'Relationships' was a significant theme - women described the benefits of continuity of care and the positive impact of peer support. Areas for improvement were explored, such as expansion and extra sensitivity around some women's issues around weight gain/loss.

DISCUSSION

HG causes significant ill-health and its impact remains undervalued. Women had highly positive experiences of attending the dedicated HG clinic. The impact of continuity and individualized care in a day-case setting improved women's experiences of this condition.

CONCLUSION

The dedicated HG clinic was highly valued by women experiencing the condition. The IRIS clinic provides much-needed validation for a medical condition with little understanding from the general public or many healthcare professionals.

Psychologic Sequelae in Early Pregnancy Complications

Early pregnancy complications, including miscarriage, ectopic pregnancies, and hyperemesis gravidarum, are common discomforts accounting for about 15% to 20% of all pregnancies. A proportion of women with early pregnancy complications will experience short- and long-term psychologic sequelae in the aftermath of pregnancy complications, including anxiety, depression, and post-traumatic stress disorder (PTSD) which are the most commonly reported psychologic reactions. This review will focus on the course and impact of these psychologic sequelae in early pregnancy complications, and the noninvasive interventions to improve mental health are also briefly discussed.

Prenatal anxiety and the associated factors among Chinese pregnant women during the COVID-19 pandemic--a smartphone questionnaire survey study

BACKGROUNDS

The uncertainty of the pandemic of Coronavirus Disease 2019 (COVID-19) brought about tremendous psychological harm for pregnant women, causing their high rates of prenatal anxiety. The impacts of COVID-19 pandemic and symptoms of pregnant status are highly linked with prenatal anxiety. Whereas, self-efficacy and support from family and friends could attenuate the development of prenatal anxiety. Thus, the purpose of the study is to evaluate the prevalence of prenatal anxiety and its influence factors among pregnant women during the pandemic of COVID-19 in Shenyang, China.

METHODS

A cross-sectional study with face-to-face interview between April 24, 2020 and May 3, 2020 during the COVID-19 pandemic was applied among pregnant women in Shenyang Women's and Children's Hospital. Chi-square tests were calculated to determine the differences in prenatal anxiety among categorical variables. Multivariable logistic regression was employed to investigate the risk factors of prenatal anxiety.

RESULTS

The percentage of prenatal anxiety (GAD-7 score ≥ 7) among pregnant women during the pandemic of COVID-19 was 34/304 (11.18%). Logistic regression indicated that vomiting (OR 4.454, 95% CI 1.113-17.821) and feeling susceptible to SARS-CoV-2 infection (OR 2.966, 95% CI 1.151-7.642) increased the odds of prenatal anxiety. Satisfaction with medical care (OR 0.303, 95% CI 0.113-0.813) and self-efficacy (OR 0.253, 95% CI 0.100-0.639) decreased the odds of prenatal anxiety. High monthly income (OR 0.246, 95% CI 0.078 ~ 0.780) reduced the chances of suffering from prenatal anxiety.

CONCLUSION

The pregnant women in China exerted a higher prevalence of prenatal anxiety during the COVID-19 pandemic than that without COVID-19 pandemic. Effective management on symptoms of pregnant status should be delivered to relieve prenatal anxiety for the pregnant women. Furthermore, interventions on self-efficacy enhancement and high-quality medical prenatal care should be provided to prevent from the susceptibility of SARS-CoV-2 infection and reduce prenatal anxiety.

Sleep Disorders in Pregnancy, Influencing Factors and Quality of Life

AIM

In our study, the frequency of sleep disturbances in pregnancy, the reasons underlying the low quality of sleep, clinical factors, and the effects on quality of life were investigated.

METHODS

The study was planned as a prospective study and included 189 pregnant women. Clinical features, laboratory results, socio-demographic status, obstetric and medical anamnesis were evaluated. The Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, the Berlin Questionnaire, Beck Depression Inventory, SF-36 quality-of-life questionnaire, and restless leg syndrome (RLS) diagnosis criteria were used for data collection.

RESULTS

We investigated sleep disorders in 110 pregnant women (58.2%). A history of premenstrual syndrome and patients with hyperemesis gravidarum, obstructive sleep apnea syndrome, Vitamin B12 deficiency, and higher TSH levels in the laboratory were found to be associated with sleep disorders. Sleep disorders and daytime sleepiness were associated with depression, physical and social functioning, pain, and disturbance in general health perception. The number of pregnant women who had two or more RLS complaints was 84 (44%).

CONCLUSION

The results of our study show that sleep disorders in pregnancy can be managed with easily applicable methods according to the risk factors and related problems.

Evaluation of psychological resilience and anxiety levels of patients with hyperemesis gravidarum diagnosis and comparison with healthy pregnant women

Objective:

To compare the psychological resilience and anxiety levels of patients diagnosed with hyperemesis gravidarum (HG) and healthy pregnant women.

Materials and Methods:

A sociodemographic data form and the Resilience scale for Adults (RSA) and the State-Trait Anxiety Inventory (STAI) were administered. The sociodemographic data form was completed by the physician, and the RSA and STAI were completed by the participant. The sample of the study consisted of 60 pregnant women with HG and hospitalized and 97 healthy voluntary pregnant women with similar characteristics to the research group without any pregnancy complications. Data were evaluated using descriptive statistical analyses, the independent samples t-test, the Mann-Whitney U test and Pearson’s correlation analysis.

Results:

The age range was 18-42 years for HG group and 20-43 years for control group. The average age of the HG group was 28.17±5.96 years and that of the control group was 29.45±5.83 years. There was no statistically significant difference between the groups in terms of pregnancy week. Regarding the prevalence of state and trait anxiety between the groups, it was found that 66.7% of the HG group had a high level of trait anxiety and 51.7% had a high level of state anxiety. It was found that 61.9% of the control group had a high level of trait anxiety and 38.1% had a high level of state anxiety. There was no difference between the healthy pregnant group and the HG group in terms of anxiety (p=0.125). It was found that there was a significant difference between the groups in terms of only sub-dimensions of RSA, which were perception of self (U=2385.00, p=0.044) and perception of future (U=2350.50, p=0.030). The perception of self and perception of future scores of the healthy control group were higher.

Conclusion:

There was no difference between the healthy pregnant group and the HG group in terms of anxiety. It was observed that the HG group had a lower perception of self and future. Apart from the usual increase in anxiety levels during pregnancy, HG accompanied by stubborn nausea and vomiting does not create an extra psychological burden, either as a cause or a result.

Mode of conception in relation to nausea and vomiting of pregnancy: a nested matched cohort study in Sweden

Nausea and vomiting of pregnancy (NVP) is a common condition reported however inconclusively among pregnancies after assisted conception. The study objective was thus to explore whether NVP is associated to mode of conception or other in vitro fertilization (IVF)-related variables. This nested matched cohort study, originating from the BASIC-project, was conducted at the Uppsala University Hospital in Sweden between 2010 and 2016. IVF pregnancies (n = 210) and age and parity-matched women with spontaneous pregnancies (n = 420) comprised the study sample. The study outcome was self-reported NVP at gestational week 17. IVF treatment and pregnancy data were obtained after scrutinization of the medical records. NVP with or without medications was not associated with mode of conception (chi-square test, p = 0.889), even after adjusting for potential confounders. In a subgroup analysis among IVF pregnancies, NVP without medication was more frequently seen in the group who received cleavage stage embryos vs blastocysts (chi-square test, p = 0.019), exhibiting a marginally significant but strongly increased effect even after adjustment [crude RRR 3.82 (95% CI 1.23–11.92) and adjusted RRR 3.42 (95% CI 0.96–12.11)]. No difference in the rate of NVP with or without medication between women that underwent fresh and frozen/thawed embryo transfers as well as IVF or ICSI was observed. Conception through IVF is not associated with NVP. Transfer of a blastocyst may decrease the risk of developing NVP and further, large-scale prospective studies are required to validate this finding.

Association Between Nausea and Vomiting During Pregnancy and Sleep Quality: Mediating Effect of Depressive Symptoms

Purpose

Nausea and vomiting during pregnancy (NVP) of varying degrees of severity are commonly experienced by pregnant women. This paper explores the association between NVP and poor sleep quality.

Patients and Methods

A cross-sectional study was conducted in an obstetrics clinic. A total of 2494 pregnant women (representing a response rate of 92.7%) completed a self-administered questionnaire.

Results

Of the 2494 participants, the mean sleep duration was 7.76 hours, and 54.3% of them report poor sleep quality (ie, a Pittsburgh Sleep Quality Index global score > 5). In this study, 49.1%, 49.3% and 1.6% women reported mild, moderate, and severe NVP, respectively. Compare with women with mild NVP, women with moderate or severe NVP were more likely to report poor sleep quality (χ ² = 30.16, p < 0.001). After adjusted for demographics and gestational age, moderate and severe NVP were associated with poor sleep quality (adjusted odds ratio (AOR) = 1.66, 95% confidence interval (CI) = 1.40-1.96, and AOR = 2.95, 95% CI = 1.44-6.02, respectively). Moreover, depressive symptoms mediated the association between NVP and poor sleep quality (β = 0.060, p = 0.033, 95% CI = 0.028-0.180).

Conclusion

Our study suggested that moderate and severe NVP increase the risk of poor sleep quality. Further studies are warranted that focus on the mechanisms of the association between NVP and poor sleep quality.

Prevalence of and Risk Factors for Poor Sleep During Different Trimesters of Pregnancy Among Women in China: A Cross-Sectional Study

BACKGROUND

The management of poor sleep during pregnancy is important for maternal and foetal health. The aim of the present study was to investigate the prevalence of poor sleep quality and risk factors for poor sleep during different trimesters of pregnancy for better management of sleep during pregnancy.

METHODS

A cross-sectional study was conducted among pregnant women in Foshan Women's and Children's Hospital. In total, 2281 pregnant women were analysed, and the Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality. Cluster logistic regression was used to analyse the risk factors for poor sleep among all participants, and logistic regression models were built to identify potential risk factors for poor sleep quality in different trimesters of pregnancy.

RESULTS

Over half of the participants reported poor sleep quality (51.8%). The rate of poor sleep was lowest in the second trimester. Women who were unmarried had >12 years of education, exercised <3 days/week, were in the third trimester, had a high level of nausea and vomiting during pregnancy (NVP) and had a history of infertility had a higher risk of poor sleep. Pregnancy-related factors contributed most to poor sleep. In the first trimester, the main risk factors for poor sleep were a history of infertility and a high level of NVP. In the second trimester, only a high level of NVP was a risk factor for poor sleep. In the last trimester, the risk factors for poor sleep were more education years, exercise <3 days/week and high levels of NVP.

CONCLUSION

The prevalence and risk factors for poor sleep were different in different trimesters. Clinicians should screen and address poor sleep prior to the first and, especially, the third trimester of pregnancy. Management of poor sleep should be consistent throughout pregnancy and be adjusted in different trimesters.

Risk Factors of Prolonged Nausea and Vomiting During Pregnancy

Background

Determination of the risk factors associated with prolonged nausea and vomiting during pregnancy (NVP) helps to develop prevention strategies. However, there is a lack of studies regarding risk factors of prolonged NVP. Thus, the potential risk factors of prolonged moderate and severe NVP were examined.

Methods

This is a retrospective study among pregnant women in South of China. The Pregnancy-Unique Quantification of Emesis (PUQE) scale was used to evaluate NVP. Onset before 12 weeks and persistence after 20 weeks of gestation were defined as prolonged NVP. Data on NVP and other variables were collected by standard questionnaires and medical records.

Results

A finally sample of 1739 participants were analyzed. The incidence of prolonged moderate and severe NVP was 42.1% and 1.1%, respectively. Among those with NVP, the increased risk of prolonged moderate NVP was associated with lower gestational age (OR = 0.95 per SD increase, 95% CI=0.93-0.97), being a housewife (OR = 1.30, 95% CI=1.02-1.65), pre-pregnant longer sedentary time (OR = 2.02, 95% CI=1.16-1.83), pre-pregnant lower exercise frequency (OR = 1.84, 95% CI=1.20-2.82), and history of gastrointestinal (GI) diseases (OR = 2.21, 95% CI=1.61-3.03). Persons who were a housewife (OR = 6.39, 95% CI=1.90-21.47), with pre-pregnant high frequent (always) cold drinking (OR=11.12, 95% CI=1.24-100.73), and had a history of GI diseases (OR=10.10, 95% CI=2.63-38.86) were more likely to experience prolonged severe NVP.

Conclusion

The results of the present study suggested that pregnant women unemployed, with lower gestational age, pre-pregnant longer sedentary time, less exercise, high frequent (always) cold drinking and history of GI diseases had a higher risk of prolonged NVP and should be taken more care.
