The psychological health of women in early pregnancy was investigated in a sample of 273 women (mean gestational age 12.8 weeks, SD=2.8) using the General Health Questionnaire (GHQ) and mood and illness perception visual analogue scales, and compared with the prevalence and severity of nausea and vomiting as measured using the Nausea and Vomiting in Pregnancy Instrument (NVPI). Using a cut-off of 4/5 for the GHQ, 50.5% of pregnant women were found to have potential psychiatric problems. However, perceived mental health and physical illness was significantly better than anticipated. The severity of nausea and vomiting correlated independently with GHQ subscales for somatic symptoms, social dysfunction, anxiety/insomnia and severe depression. The contradiction between high GHQ scored and high perceived wellbeing might be explained through cognitive processing. Nausea and vomiting in early pregnancy is associated with psychiatric morbidity. The causal relationship between the two conditions has not been established.
BackgroundNausea and vomiting in pregnancy (NVP) affects up to 85% of all women during pregnancy, but for the majority self-management suffices. For the remainder, symptoms are more severe and the most severe form of NVP – hyperemesis gravidarum (HG) – affects 0.3–1.0% of pregnant women. There is no widely accepted point at which NVP becomes HG.ObjectivesThis study aimed to determine the relative clinical effectiveness and cost-effectiveness of treatments for NVP and HG.Data sourcesMEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials, PsycINFO, Commonwealth Agricultural Bureaux (CAB) Abstracts, Latin American and Caribbean Health Sciences Literature, Allied and Complementary Medicine Database, British Nursing Index, Science Citation Index, Social Sciences Citation Index, Scopus, Conference Proceedings Index, NHS Economic Evaluation Database, Health Economic Evaluations Database, China National Knowledge Infrastructure, Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effects were searched from inception to September 2014. References from studies and literature reviews identified were also examined.Obstetric Medicinewas hand-searched, as were websites of relevant organisations. Costs came from NHS sources.Review methodsA systematic review of randomised and non-randomised controlled trials (RCTs) for effectiveness, and population-based case series for adverse events and fetal outcomes. Treatments: vitamins B6 and B12, ginger, acupressure/acupuncture, hypnotherapy, antiemetics, dopamine antagonists, 5-hydroxytryptamine receptor antagonists, intravenous (i.v.) fluids, corticosteroids, enteral and parenteral feeding or other novel treatment. Two reviewers extracted data and quality assessed studies. Results were narratively synthesised; planned meta-analysis was not possible due to heterogeneity and incomplete reporting. A simple economic evaluation considered the implied values of treatments.ResultsSeventy-three studies (75 reports) met the inclusion criteria. For RCTs, 33 and 11 studies had a low and high risk of bias respectively. For the remainder (n = 20) it was unclear. The non-randomised studies (n = 9) were low quality. There were 33 separate comparators. The most common were acupressure versus placebo (n = 12); steroid versus usual treatment (n = 7); ginger versus placebo (n = 6); ginger versus vitamin B6 (n = 6); and vitamin B6 versus placebo (n = 4). There was evidence that ginger, antihistamines, metoclopramide (mild disease) and vitamin B6 (mild to severe disease) are better than placebo. Diclectin®[Duchesnay Inc.; doxylamine succinate (10 mg) plus pyridoxine hydrochloride (10 mg) slow release tablet] is more effective than placebo and ondansetron is more effective at reducing nausea than pyridoxine plus doxylamine. Diclectin before symptoms of NVP begin for women at high risk of severe NVP recurrence reduces risk of moderate/severe NVP compared with taking Diclectin once symptoms begin. Promethazine is as, and ondansetron is more, effective than metoclopramide for severe NVP/HG. I.v. fluids help correct dehydration and improve symptoms. Dextrose saline may be more effective at reducing nausea than normal saline. Transdermal clonidine patches may be effective for severe HG. Enteral feeding is effective but extreme method treatment for very severe symptoms. Day case management for moderate/severe symptoms is feasible, acceptable and as effective as inpatient care. For all other interventions and comparisons, evidence is unclear. The economic analysis was limited by lack of effectiveness data, but comparison of costs between treatments highlights the implications of different choices.LimitationsThe main limitations were the quantity and quality of the data available.ConclusionThere was evidence of some improvement in symptoms for some treatments, but these data may not be transferable across disease severities. Methodologically sound and larger trials of the main therapies considered within the UK NHS are needed.Study registrationThis study is registered as PROSPERO CRD42013006642.FundingThe National Institute for Health Research Health Technology Assessment programme.
The use of the 28-item version of the General Health Questionnaire as a means of determining prevalence of psychiatric disorders in early pregnancy is described. Two hundred and seventy-three women attending their first antenatal appointment completed the instrument. Positive cases identified by both the GHQ scoring method (cut-off score 5/6) and the Likert method (cut-off score 23/24) were compared. Using the GHQ method, 44.3% of the women scored 5 or above; 50.5% scored 4 or above. Using the Likert method, 39.6% scored 24 or above. The GHQ method identified 21 cases undetected by the Likert (17%) and the Likert method identified eight cases undetected by the GHQ (7.4%). The results indicate higher prevalence rates than found in community samples. Pending further research, it is recommended that the GHQ be used with caution in antenatal setting
To test the relationship between schizotypal symptoms and cannabis use in a non-clinical population, cannabis users and non-users were asked to complete the Schizotypal Personality Questionnaire. Significant differences in scores between the groups were observed. There may be a developmental process in the relationship between cannabis use and schizotypal symptoms.
