Hyperemesis gravidarum and eating disorders before and after pregnancy: A register-based study.

OBJECTIVE: Hyperemesis gravidarum (HG) is a severe form of excessive vomiting during pregnancy. The connection between psychiatric morbidity and HG has been debated, but only a few studies have focused on eating disorders (EDs). The objective of this study was to evaluate the association between HG and both pre-pregnancy and new post-pregnancy EDs. METHODS: A register-based controlled study. HG diagnoses were retrieved from healthcare registers between 2005 and 2017. Women with HG in their first pregnancy resulting in delivery were chosen as cases (n = 4265; the HG group) and women with no HG as controls (n = 302,663; the non-HG group). The associations between EDs and HG were analyzed by binary logistic regression, adjusted with age, body mass index, smoking, socioeconomic status, and pre-pregnancy psychiatric diagnoses. RESULTS: In the HG group, 1.6% and in the non-HG group, 0.2% had a pre-pregnancy ED. Women with ED were more likely to have HG in their first pregnancy compared with women with no history of EDs (adjusted odds ratio [AOR] 9.4, 95% CI 6.52-13.66, p < .0001). Moreover, 0.4% of the women in the HG group and 0.1% of the women in the non-HG group had a new ED diagnosis after pregnancy, and thus the women in the HG group were more likely to have an ED diagnosis after pregnancy (AOR I 3.5, 95% CI 1.71-7.15, p < .001, AOR II 2.7, 95% CI 1.30-5.69, p = .008). DISCUSSION: We found a bidirectional association between ED and HG, suggesting a shared etiology or risk factors between these disorders. This finding emphasizes the importance of collaboration across various specialties when treating these patients. PUBLIC SIGNIFICANCE: Our findings suggest a bidirectional association between HG and EDs before and after pregnancy. This finding provides essential information for healthcare professionals working with pregnant women. As both of these disorders are known to have far-reaching effects on the lives of both the mother and her offspring, our results help clinicians to target special attention and interventions to the patients suffering from these disorders.

Hyperemesis gravidarum: Associations with personal and family history of nausea.

INTRODUCTION: The pathogenesis and risk factors for hyperemesis gravidarum, excessive nausea and vomiting of pregnancy, are not adequately recognized. In our previous study, we found that women with a personal history of nausea in different situations and a family history of nausea and vomiting of pregnancy (NVP) were more likely to have severe NVP. The present study focuses on these themes in association with hyperemesis gravidarum in a hospital setting. MATERIAL AND METHODS: Women with hyperemesis gravidarum (n = 102) were recruited from among patients hospitalized due to hyperemesis gravidarum in Turku University Hospital, Finland. Our control group (Non-NVP group, n = 138) consisted of pregnant women with no NVP. Personal history of nausea in different situations was inquired about in relation to "motion sickness", "seasickness", "migraine", "other kind of headache", "after anesthesia", "during the use of contraception", and "other kinds of nausea". Relatives with NVP were divided into first-degree (mother and sisters) and second-degree (more distant) relatives. RESULTS: In univariate analysis, a personal history of motion sickness, seasickness, nausea related to migraine, nausea with other headache and nausea in other situations were associated with hyperemesis gravidarum. After adjusting for age, parity, pre-pregnancy body mass index, marital status, and smoking, motion sickness (adjusted odds ratio [aOR] 5.24, 95% confidence interval [CI] 2.67-10.31, p < 0.0001), seasickness (aOR 4.82, 95% CI 2.32-10.03, p < 0.0001), nausea related to migraine (aOR 3.00, 95% CI 1.58-5.70, p < 0.001), and nausea in other situations (aOR 2.65, 95% CI 1.13-6.20, p = 0.025) remained significant. In multivariable analysis with all history of nausea variables, motion sickness (OR 2.76, 95% CI 1.29-5.89, p = 0.009) and nausea related to migraine (OR 3.10, 95% CI 1.40-6.86, p = 0.005) were associated with hyperemesis gravidarum. Having any affected relative (OR 3.51, 95%CI 1.84-6.73, p = 0.0002), especially a first-degree relative (OR 3.06, 95% CI 1.62-5.79, p = 0.0006), was also associated with hyperemesis gravidarum. Adjustment did not change the results. CONCLUSIONS: Women with a personal history of nausea or a family history of NVP are more likely to suffer from hyperemesis gravidarum. These results are beneficial to better identify and help women at risk for hyperemesis gravidarum.

Sleep quality in women with nausea and vomiting of pregnancy: a cross-sectional study.

BACKGROUND: Nausea and vomiting of pregnancy (NVP) deteriorates many aspects of daily lives of women. However, little is known about associations between NVP and sleep quality. METHODS: Women attending to routine mid-pregnancy visits in maternity health care clinics in Turku city area and surrounding municipalities, Finland, during 2011-2014, were invited to participate. A cohort of 1203 volunteers (mean age 30 years, mean gestational week 16.6, mean BMI 24.4 kg/m2, nulliparous 46%) was recruited. The severity of NVP in the worst 12-h period of current pregnancy was assessed with Pregnancy Unique Quantification of Emesis Questionnaire (PUQE) and categorized accordingly into no/mild/moderate and severe NVP. Sleep disturbances during the past 3 months were assessed with selected questions (difficulty falling asleep, night awakenings, too early morning awakenings and sleepiness during the day) from Basic Nordic Sleep Questionnaire (BNSQ). In addition, general sleep quality, as well as physical and mental quality of life (QoL) were rated with three visual analog scales (VAS). Associations between PUQE categories (severity of NVP) and sleep disturbances, general sleep quality, physical QoL and mental QoL were evaluated with multinomial regression analysis. RESULTS: According to PUQE, NVP was most frequently moderate (n = 629, 52.3%), followed by mild (n = 361, 30.0%) and severe (n = 77, 6.4%). Only 11.3% had no NVP (n = 136). The most frequent sleep disturbance was night awakenings (69.9%, n = 837), followed by sleepiness during the day (35.7%, n = 427), too early morning awakenings (12.0%, n = 143) and difficulty falling asleep (7.1%, n = 81). In adjusted analysis (age, parity, body mass index, smoking, employment), more severe NVP was associated with night awakenings (AOR 3.9, 95% CI 1.79-8.47, P < 0.0001) and sleepiness during the day (AOR 4.7, 95% CI 2.20-9.94, P < 0.0001). In VAS, women with more severe NVP rated worse general sleep quality and worse physical and mental QoL. However, in multivariable analysis, the association between the severity of NVP and physical and mental QoL was stronger than that of sleep . CONCLUSIONS: More severe NVP is associated with sleep disturbances and in close relation to lower physical and mental QoL. Thus, in comprehensive care of women with NVP, also sleep quality should be evaluated.

Nausea and vomiting of pregnancy: associations with personal history of nausea and affected relatives.

PURPOSE: To examine whether personal history of nausea or history of nausea and vomiting of pregnancy (NVP) in relatives are risk factors for a woman to suffer from NVP. Further, to evaluate if these factors are associated with the severity of NVP. METHODS: Cohort study of 2411 pregnant women recruited from maternity health care clinics. The severity of NVP was categorized according to Pregnancy-Unique Quantification of Emesis (PUQE) questionnaire into no/mild/moderate/severe NVP. History of nausea was assessed in connection with motion sickness, seasickness, migraine or other kinds of headache, after anesthesia, related to the use of contraceptives, and other kinds of nausea. History of NVP in relatives was categorized into first-degree (mother/sister) and second-degree relatives (more distant). RESULTS: In multivariable analysis including previous personal history of nausea, motion sickness (OR 3.17, 95% CI 1.81-5.56, p < 0.0001) and nausea in migraine (OR 3.18, 95% CI 1.86-5.45, p < 0.0001) were associated with severe NVP. History of nausea in other kinds of headache was associated with moderate NVP (OR 1.91, 95% CI 1.34-2.72, p = 0.001). Women with affected first-degree relatives had higher odds for moderate (OR 3.84, 95% CI 2.72-5.40) and severe (OR 3.19, 95% CI 1.92-5.28) NVP (p < 0.0001). All these results remained significant after adjusting for parity, body mass index, smoking, employment and age. CONCLUSION: Women with personal history of nausea or family history of NVP have an increased susceptibility of NVP. This information is useful in pre-pregnancy counselling.

Nausea and vomiting of pregnancy: A study with pregnancy-unique quantification of emesis questionnaire.

OBJECTIVES: Nausea and vomiting of pregnancy (NVP) is frequent, affecting up to 70-85% of pregnant women. However, severity of NVP especially in clinical practice is often uncertainly assessed and thus both under- and overdiagnosing is probable. Furthermore, risk factors for NVP, although recognized, are not well established. The aim of our study was to evaluate the severity of NVP with a structured questionnaire and evaluate associative risk factors. STUDY DESIGN: Sample of 2411 women were recruited from maternity health care clinics. Severity of NVP was assessed with pregnancy-unique quantification of emesis (PUQE) questionnaire. Age, previous pregnancies, previous deliveries, previous miscarriages including ectopic pregnancies, previous pregnancy terminations, nationality, pre-pregnancy body mass index, smoking, marital status and employment were used as explanatory factors. RESULTS: Altogether 88.0% of the women reported some level of NVP, of which 6.4% was severe, 52.2% moderate and 29.4% mild. Daily duration of NVP was ≥ four hours in 12 h in 45.0%. Further, 18.8% of the women had vomiting episodes ≥ three times and 37.4% retching episodes ≥ three times in 12 h. Women with ≥ two previous pregnancies had increased risk for more severe NVP (OR 2.17, 95%CI; 1.34-3.51, p < 0.0001). Older women had increased daily duration of nausea (OR 1.03, 95%CI; 1.00-1.06, p = 0.004) but lower number of vomits (OR 0.93, 95%CI; 0.93-0.97, p < 0.0001) and lower number of retching (OR 0.93, 95%CI; 0.90-0.96, p < 0.0001). Smokers had shorter daily duration of nausea (OR 0.49, 95%CI; 0.33-0.73, p < 0.0001), but higher number of vomiting episodes compared to non-smokers (OR 1.83, 95%CI; 1.26-2.66, p = 0.021). CONCLUSIONS: Women suffered from NVP very frequently. The daily duration of NVP was moderately long, in nearly half of the women four hours or more. In addition, retching was more frequent than vomiting. From studied risk factors, few associations with different aspects of NVP emerged, but only multiparity was associated with the severity of NVP. As NVP affects several women during pregnancy, in future, the impact of NVP on quality of life, future family planning and health costs should be evaluated.
