Association between postpartum thyroid dysfunction and thyroid antibodies and depression.

OBJECTIVE--To define the relation between mood and autoimmune thyroid dysfunction during the eight months after delivery. DESIGN--Double blind comparison of the psychiatric status of women positive and negative for thyroid antibodies. Clinical examination and blood sampling for free triiodothyronine and thyroxine, thyroid stimulating hormone, and thyroid antibody concentrations at four weekly intervals. Psychiatric assessment at six, eight, 12, 20, and 28 weeks post partum. SETTING--Outpatient department of district hospital. PATIENTS--145 antibody positive women and 229 antibody negative women delivering between August 1987 and December 1989. MAIN OUTCOME MEASURES--Thyroid status. Number of cases of mental ill health by the general health questionnaire, research diagnostic criteria, Hamilton 17 item depression scale, hospital anxiety and depression scale, and Edinburgh postnatal depression scale. RESULTS--Six weeks after delivery the general health questionnaire showed 62 (43%) antibody positive women and 65 (28%) antibody negative women had mental ill health (chi 2 = 8.18, p less than 0.005). Follow up of 110 antibody positive and 132 antibody negative women showed significantly greater depression by research diagnostic criteria in antibody positive women (47%) than antibody negative women (32%) regardless of thyroid dysfunction. Antibody positive women showed higher mean scores for depression on the Hamilton (6.01 v 3.89, p = 0.0002), Edinburgh (7.45 v 5.92, p = 0.031), and hospital depression scales (4.95 v 3.79, p = 0.003). CONCLUSION--Depressive symptoms are associated with positive thyroid antibody status in the postpartum period.     

A controlled study of fluoxetine and cognitive-behavioural counselling in the treatment of postnatal depression.

OBJECTIVE: To study the effectiveness of fluoxetine and cognitive-behavioural counselling in depressive illness in postnatal women: to compare fluoxetine and placebo, six sessions and one session of counselling, and combinations of drugs and counselling. DESIGN: Randomised, controlled treatment trial, double blind in relation to drug treatment, with four treatment cells: fluoxetine or placebo plus one or six sessions of counselling. SUBJECTS: 87 women satisfying criteria for depressive illness 6-8 weeks after childbirth, 61 (70%) of whom completed 12 weeks of treatment. SETTING: Community based study in south Manchester. MAIN OUTCOME MEASURES: Psychiatric morbidity after 1, 4, and 12 weeks, measured as mean scores and 95% confidence limits on the revised clinical interview schedule, the Edinburgh postnatal depression scale and the Hamilton depression scale. RESULTS: Highly significant improvement was seen in all four treatment groups. The improvement in subjects receiving fluoxetine was significantly greater than in those receiving placebo. The improvement after six sessions of counselling was significantly greater than after a single session. Interaction between counselling and fluoxetine was not statistically significant. These differences were evident after one week, and improvement in all groups was complete after four weeks. CONCLUSIONS: Both fluoxetine and cognitive-behavioural counselling given as a course of therapy are effective treatments for non-psychotic depression in postnatal women. After an initial session of counselling, additional benefit results from either fluoxetine or further counselling but there seems to be no advantage in receiving both. The choice of treatment may therefore be made by the women themselves.     

Support after perinatal death: a study of support and counselling after perinatal bereavement.

After an earlier study into the practical aspects of the management of perinatal death, a counselling service was introduced for parents whose baby had died in the perinatal period. The service was monitored, and the parents who received the service were compared with a group that did not. Fifty families were allocated randomly either to the counselling (supported) group or to the contrast group, who received routine hospital care. Assessment was carried out at six and 14 months after the death, using a semi-structured interview and two self-rating scales (the general health questionnaire and the Leeds scales). Two of 16 mothers in the supported group showed psychiatric disorder at six months, compared with 10 of 19 in the contrast group (p less than 0.01, Fisher''s exact test). There was no significant difference between the two groups at 14 months, when 80% of all the women studied had recovered psychiatric symptoms. Socially isolated women and those who marital relations lacked intimacy had a higher incidence of psychiatric symptoms at six months. Early pregnancy (within six months) was associated with a higher incidence of psychiatric symptoms in the unsupported group. The duration of bereavement reaction after perinatal death was appreciably shortened by support and counselling.     

Psychological outcomes of different treatment policies in women with early breast cancer outside a clinical trial.

OBJECTIVES--To assess outside a clinical trial the psychological outcome of different treatment policies in women with early breast cancer who underwent either mastectomy or breast conservation surgery depending on the surgeon''s opinion or the patient''s choice. To determine whether the extent of psychiatric morbidity reported in women who underwent breast conservation surgery was associated with their participation in a randomised clinical trial. DESIGN--Prospective, multicentre study capitalising on individual and motivational differences among patients and the different management policies among surgeons for treating patients with early breast cancer. SETTING--12 District general hospitals, three London teaching hospitals, and four private hospitals. PATIENTS--269 Women under 75 with a probable diagnosis of stage I or II breast cancer who were referred to 22 different surgeons. INTERVENTIONS--Surgery and radiotherapy or adjuvant chemotherapy, or both, depending on the individual surgeon''s stated preferences for managing early breast cancer. MAIN OUTCOME MEASURES--Anxiety and depression as assessed by standard methods two weeks, three months, and 12 months after surgery. RESULTS--Of the 269 women, 31 were treated by surgeons who favoured mastectomy, 120 by surgeons who favoured breast conservation, and 118 by surgeons who offered a choice of treatment. Sixty two of the women treated by surgeons who offered a choice were eligible to choose their surgery, and 43 of these chose breast conserving surgery. The incidences of anxiety, depression, and sexual dysfunction were high in all treatment groups. There were no significant differences in the incidences of anxiety and depression between women who underwent mastectomy and those who underwent lumpectomy. A significant effect of surgeon type on the incidence of depression was observed, with patients treated by surgeons who offered a choice showing less depression than those treated by other surgeons (p = 0.06). There was no significant difference in psychiatric morbidity between women treated by surgeons who offered a choice who were eligible to choose their treatment and those in the same group who were not able to choose. Most of the women (159/244) gave fear of cancer as their primary fear rather than fear of losing a breast. The overall incidences of psychiatric morbidity in women who underwent mastectomy and those who underwent lumpectomy were similar to those found in the Cancer Research Campaign breast conservation study. At 12 months 28% of women who underwent mastectomy in the present study were anxious compared with 26% in the earlier study, and 27% of women in the present study who underwent lumpectomy were anxious compared with 31% in the earlier study. In both the present and earlier study 21% of women who underwent mastectomy were depressed, and 19% of women who underwent lumpectomy in the present study were depressed compared with 27% in the earlier study.) CONCLUSIONS--There is still no evidence that women with early breast cancer who undergo breast conservation surgery have less psychiatric morbidity after treatment than those who undergo mastectomy. Women who surrender autonomy for decision making by agreeing to participate in randomised clinical trials do not experience any different psychological, sexual, or social problems from those women who are treated for breast cancer outside a clinical trial.     

Breastfeeding and the Basal Insulin Requirement in Type 1 Diabetic Women

ObjectiveTo evaluate whether breastfeeding in women with type 1 diabetes mellitus is associated with a decreased insulin requirement.MethodsIn this prospective study conducted between September 2006 and August 2008, type 1 diabetic pregnant women were recruited before the third trimester of pregnancy. Eligible women had no evidence of diabetes-related complications and were treated with continuous subcutaneous insulin infusion pump therapy. During pregnancy and in the first 8 weeks of the postpartum period, participants performed daily fingerstick blood glucose monitoring with at least 12 measurements per day; insulin dosages were adjusted to maintain normoglycemia. Participant characteristics, diabetic parameters, and neonatal growth were compared between women who breastfed exclusively and women who did not breastfeed.ResultsOf 18 women, 12 breastfed and 6 did not. Compared with nonbreastfeeding mothers, breastfeeding mothers showed a decreased need for total daily basal insulin (0.21 ± 0.05 units/kg per day vs 0.33 ± 0.02 units/kg per day). The mean value of total daily basal insulin was significantly lower in the breastfeeding group than in the nonbreastfeeding group. The mean number of hyperglycemic episodes in the first 2 weeks post partum and during the third to eighth weeks was not different between the groups.However, the mean number of hypoglycemic episodes in the first 2 weeks post partum in the breastfeeding group was significantly higher than in the nonbreastfeeding group (11.9 ± 2.6 episodes vs 5.5 ± 1.6 episodes, P < .001). No differences were observed between the groups in neonatal birth weight or infant weight after 8 weeks of age.ConclusionsDecreased need in total daily basal insulin is caused by increased glucose use during lactation. We recommend that the starting total daily basal insulin dosage for type 1 diabetic women who breastfeed be calculated as 0.21 units times the weight in kg per day. This regimen results in normoglycemia and minimizes the risk of severe hypoglycemia associated with lactation. (Endocr Pract. 2009;15:187-193)     

Postpartum thyroid dysfunction in Mid Glamorgan

A high prevalence of postpartum thyroid dysfunction has been reported in several countries, but there have been no systematic studies of its prevalence in Britain. Among a group of 901 consecutive, unselected pregnant women thyroid autoantibodies were detected in 117 (13%) at booking. The clinical course of postpartum thyroid dysfunction, factors associated with its development, and its likely prevalence were defined in 100 of these women with thyroid antibodies and 120 women with no such antibodies who were matched for age. None of the women had a history of autoimmune thyroid disease. Normal reference ranges for thyroid function during pregnancy and post partum were established in the 120 women negative for thyroid antibodies. On the basis of these observations postpartum thyroid dysfunction was observed in 49 (22%) of the 220 women studied, and the prevalence in the total group of 901 women was estimated to be 16·7%. Thyroid dysfunction, mainly occurring in the first six months post partum, was usually transient and included both destruction induced hyperthyroidism and hypothyroidism. The development of the syndrome was significantly related to smoking more than 20 cigarettes a day and the presence of thyroid microsomal autoantibodies at booking. Of the 16 women with a family history of thyroid disease in whom thyroid microsomal autoantibody activity was detectable at booking, 11 developed thyroid dysfunction. Age, parity, presence of goitre at presentation, duration of breast feeding, and the sex and birth weight of the infant were not associated with the development of postpartum thyroid dysfunction.The mood changes experienced by women post partum may in part be associated with altered thyroid function during this time.     

Psychosocial and psychological interventions for prevention of postnatal depression: systematic review

Objective To assess the effects of psychosocial and psychological interventions compared with usual antepartum, intrapartum, or postpartum care on the risk of postnatal depression.Data sources Medline, Embase, CINAHL, Cochrane central register of controlled trials, Cochrane pregnancy and childbirth group trials register, Cochrane depression, anxiety, and neurosis trials register, secondary references and review articles, and experts in the field.Study selection All published and unpublished randomised controlled trials of preventive psychosocial or psychological interventions in which the primary or secondary aim was a reduction in the risk of postnatal depression. All trials recruited pregnant women or new mothers less than six weeks postpartum. Eligible studies were abstracted, assessed for methodological quality, and pooled with relative risk for categorical data and weighted mean difference for continuous data.Results Fifteen trials with 7697 women were included. Although there was no overall statistically significant effect on the prevention of postnatal depression in the meta-analysis of all types of interventions (15 trials, n = 7697; relative risk 0.81, 95% confidence interval 0.65 to 1.02), these results suggest a potential reduction in postnatal depression. The only intervention to have a clear preventive effect was intensive postpartum support provided by a health professional (0.68, 0.55 to 0.84). Identifying women “at risk” assisted in the prevention of postnatal depression (0.67, 0.51 to 0.89). Interventions with only a postnatal component were more beneficial (0.76, 0.58 to 0.98) than interventions that incorporated an antenatal component. In addition, individually based interventions were more effective (0.76, 0.59 to 1.00) than group based interventions (1.03, 0.65 to 1.63).Conclusions Diverse psychosocial or psychological interventions do not significantly reduce the number of women who develop postnatal depression. The most promising intervention is the provision of intensive, professionally based postpartum support.     

Development and First Phase Evaluation of a Maternity Leave Educational Tool for Pregnant,Working Women in California

Background

Despite the provision of maternity leave offered to mothers, many American women fail to take leave.

Methods

We developed an evidence-based maternity leave educational tool for working women in California using participatory design. We tested its short-term efficacy with a randomized controlled trial of pregnant English-speakers (n=155).

Results

Among intervention participants exposed to the tool, 65% reported that they learned something new; 38% were motivated to seek more information; and 49% said it helped them plan their maternity leave. Among participants who delivered at ≥ 37 weeks gestation and said the tool helped them plan their leave, 89% took more than one week of prenatal leave, a significantly higher proportion than among controls who did not receive the tool (64%, p=0.049). Other findings favored trial participants, but were not statistically significant in this small sample. More intervention participants took some prenatal leave (80%) vs. controls (74%, p=0.44). Among participants who had returned to work when surveyed (n=50), mean postnatal leave uptake was on average 1 week longer for intervention participants vs. controls (13.3 vs. 12.2 weeks, p=0.54).

Conclusions

The first-phase evaluation of this tool shows that it successfully informed women about maternity leave options, clarified complex regulations, encouraged women to seek further information and helped plan maternity leave. Compared to controls, trial participants who used the tool to plan their leave were far more likely to take prenatal leave close to term. Future evaluation of the tool when mediated by a health provider or employer is warranted.     

Stillbirth as risk factor for depression and anxiety in the subsequent pregnancy: cohort study

ObjectiveTo assess women’s symptoms of depression and anxiety during pregnancy and the postpartum year in the pregnancy after stillbirth; to assess relevance of time since loss.DesignCohort study with four assessments: in third trimester and 6 weeks, 6 months, and 12 months after birth.SettingOutpatient departments of three district general hospitals; subjects’ homes.Subjects60 women whose previous pregnancy ended in stillbirth after 18 weeks’ gestation; 60 matched controls.ResultsIn the third trimester women whose previous pregnancy had ended in stillbirth were significantly more depressed than control women (10.8 v 8.2; P=0.004) and had greater state anxiety (39.8 v 32.8, P=0.003) The difference was accounted for by those women who conceived less than 12 months after the stillbirth, who were also more depressed at 1 year. Results in those who conceived 12 months or more after stillbirth were similar to those in their controls at all points and showed lower trait anxiety 1 year post partum. One year after the birth 8% of control women and 19% of subjects scored high for depression (P=0.39), with most of the depression among the more recently bereaved (28% v 11%; P=0.18). In the women who had experienced stillbirth, depression in the third trimester was highly predictive of depression 1 year after subsequent birth (P⩽0.0005).ConclusionVulnerability to depression and anxiety in the next pregnancy and puerperium is related to time since stillbirth, with more recently bereaved women at significantly greater risk than controls. As there are problems for mother and infant associated with high anxiety and depression during and after pregnancy, there may be advantage in waiting 12 months before the next conception.

Key messages

• Women whose previous pregnancy ended in stillbirth had significantly higher levels of depression and state anxiety during their subsequent pregnancy than matched controls
• Those who had conceived over 12 months after stillbirth were, however, similar to controls at all points and had lower trait anxiety a year after the next birth
• Women who had conceived within 12 months after loss had a significantly higher risk of high state anxiety during the next pregnancy and of depression and both state and trait anxiety 12 months post partum than women with longer time since loss
• Women may need a year to mourn the lost child before beginning another pregnancy or women who chose to conceive sooner may be intrinsically more vulnerable to depression and anxiety
• Parents have various and individual reasons for timing the next pregnancy, but there may be advantage in waiting 12 months before conception

     

Is telephone counselling a useful addition to physician advice and nicotine replacement therapy in helping patients to stop smoking? A randomized controlled trial

BACKGROUND: The authors evaluated the incremental efficacy of telephone counselling by a nurse in addition to physician advice and nicotine replacement therapy in helping patients to stop smoking. METHODS: The trial was conducted at the University of Ottawa Heart Institute. A total of 396 volunteers who smoked 15 or more cigarettes daily were randomly assigned to either of 2 groups: usual care (control group) and usual care plus telephone counselling (intervention group); the groups were stratified by sex and degree of nicotine dependence. Usual care involved the receipt of physician advice on 3 occasions, self-help materials and 12 weeks of nicotine replacement therapy. Telephone counselling was provided by a nurse at 2, 6 and 13 weeks after the target quit date. Point-prevalent quit rates were determined at 52 weeks after the target quit date. RESULTS: The point-prevalent quit rates at 52 weeks did not differ significantly between the control and intervention groups (24.1% v. 23.4% respectively). The quit rates did not differ significantly at the secondary measurement points of 4, 12 and 26 weeks. INTERPRETATION: Brief physician assistance, along with nicotine replacement therapy, can help well-motivated smokers to quit. Three additional sessions of telephone counselling by a nurse were ineffective in increasing quit rates. This form of assistance may be useful in the absence of physician advice or when self-selected by patients.     

Electroconvulsive therapy: results in depressive illness from the Leicestershire trial.

Electroconvulsive therapy was investigated in a double blind trial. Altogether 186 clinically selected patients were referred to the trial, but 48 of these did not participate. According to the present state examination, 95 of the remaining 138 patients fell into one of the classes of major depression. Patients were randomly allocated to a course of real or simulated electroconvulsive therapy. Treatment was given twice a week with a maximum of eight treatments. On the Hamilton depressive rating scale the improvement in the group given real treatment was significantly greater than that in the group given simulated treatment both at two weeks (p = 0.014) and at four weeks (p = 0.0001). At follow up at 12 and 28 weeks there was no difference between the treatment groups. At the end of the four week trial consultants, who were blind to the allocation of treatment, rated the patients who had received real treatment as having made a significantly greater improvement than the patients who had received simulated treatment (p less than 0.00005). Further analysis showed that electroconvulsive therapy was effective in depression associated with delusions and in depression associated with retardation.     

A study of contraception as related to multiple unwanted pregnancies

A group of 25 women who had had two or more therapeutic abortions was compared with a control group of 100 women who had had only one abortion. The two groups could not be distinguished on the basis of the available demographic data. Emotional problems that interfere with the proper utilization of contraceptives were apparent in the index group and 76% of patients in this group had a primary psychiatric disorder as compared with 52% in the control group. The most common psychiatric diagnosis in the index group was chronic depressive reaction. A therapeutic abortion in the index group did not prompt an increased or more effective utilization of contraceptives.     

Promotion of breast-feeding in a Chinese community in Montreal.

Following a prospective survey that showed a very low rate of breast-feeding (10%) in 1977-79 among Chinese women in Montreal, a culturally targeted program, which included individual prenatal counselling and a community-wide promotion and education campaign, was developed to improve the rates. The study group consisted of all Chinese women delivering in 1980 and 1981 who had taken their infants to one pediatrician for continuing care. The rates of breast-feeding in the 88 women who had received prenatal counselling and the 93 women who had not were compared. Although the rates were substantially increased for both groups over the 1977-79 rate (54% and 34% in 1980 and 65% and 55% in 1981 respectively), the 2-year rate was significantly higher for the counselled group compared with the uncounselled group in the later study (59% v. 43%). The greatest effect of counselling was seen in young, primiparous women of higher socioeconomic status who spoke French or English in addition to Chinese. However, 33% of the counselled women who had started breast-feeding had stopped by 1 month, compared with only 15% of the uncounselled women. Thus, although the rates of breast-feeding in ethnic groups can be increased with the use of a language- and culture-specific approach, more support and encouragement must be given to women who start breast-feeding so that they will continue longer.     

Effect of counselling on the psychiatric morbidity associated with mastectomy.

A controlled trial was conducted to determine whether counselling by a specialist nurse prevented the psychiatric morbidity associated with mastectomy and breast cancer. Seventy-five patients were counselled by the nurse and monitored during follow-up, while 77 patients received only the care normally given by the surgical unit. Counselling failed to prevent morbidity, but the nurse''s regular monitoring of the women''s progress led her to recognise and refer 76% of those who needed psychiatric help. Only 15% of the control group whose condition warranted help were recognised and referred. Consequently, 12 to 18 months after mastectomy there was much less psychiatric morbidity in the counselled group (12%) than in the control group (39%). These findings highlight the high degree of psychiatric morbidity in patients who have undergone mastectomy and indicate the need to find ways of reducing this morbidity.     

Psychiatric problems in the first year after mastectomy.

The psychiatric morbidity associated with mastectomy was assessed in 75 women by following them up from the time they presented with suspected breast cancer to one year after the operation. Fifty women with benign breast disease served as controls. Throughout the follow-up period the incidence of psychiatric problems was higher among the women who had undergone mastectomy. One year after surgery 19 (25%) of these women compared with only 5 (10%) of the controls needed treatment for anxiety or depression or both, and 16 (33%) compared with 3 (8%) respectively had moderate or severe sexual difficulties. Altogether 29 patients in the mastectomy group (39%) and six of the controls (12%) had serious anxiety, depression, or sexual difficulties. Of the eight women in the mastectomy group who sought help for their problems, only two felt that the help given had been appropriate. The inability to recognise and treat these emotional disturbances is a common and serious problem. Monitoring by specially trained nurses and social workers might help to identify them earlier and even reduce them.     

Randomised trial comparing hysterectomy with endometrial ablation for dysfunctional uterine bleeding: psychiatric and psychosocial aspects.

OBJECTIVE: To compare in psychiatric and psychosocial terms the outcome of hysterectomy and endometrial ablation for the treatment of dysfunctional uterine bleeding. DESIGN: Prospective randomised controlled trial. SETTING--Obstetrics and gynaecology department of a large teaching hospital. SUBJECTS: 204 women with dysfunctional bleeding for whom hysterectomy would have been the preferred treatment were recruited over 24 months and randomly allocated to hysterectomy (99 women) or to hysteroscopic surgery (transcervical resection (52 women) or laser ablation (53 women). MAIN OUTCOME MEASURES: Mental state, martial relationship, psychosocial and sexual adjustment in assessments conducted before the operation and one month, six months, and 12 months later. RESULTS: Both treatments significantly reduced the anxiety and depression present before the operation, and there were no differences in mental health between the groups at 12 months. Hysterectomy did not lead to postoperative psychiatric illness. Sexual interest after the operation did not vary with treatment. Overall, 46 out of 185 (25%) women reported a loss sexual interest and 50 out of 185 (27%) reported increased sexual interest. Marital relationships were unaffected by surgery. Personality and duration of dysfunctional uterine bleeding played no significant part in determining outcome. CONCLUSIONS: Hysteroscopic surgery and hysterectomy have a similar effect on psychiatric and psychosocial outcomes. There is no evidence that hysterectomy leads to postoperative psychiatric illness.     

Effects of postparturient uterine lavage on uterine involution in the mare

Eighteen postparturient mares were used to evaluate effects of uterine lavage on uterine involution. Mares were randomly assigned to one of three treatment groups: Group 1 (seven mares), no lavage; Group 2 (five mares), lavage on Day 3 post partum; and Group 3 (six mares), lavage on Days 3, 4, and 5 post partum. Five liters sterile physiologic saline, prewarmed to 42 degrees C, were used for each lavage. Transrectal ultrasound examination of the reproductive tract was performed on Day 11 post partum to detect the presence of free fluid in the uterine lumen, to estimate the cross-sectional diameter of the uterine horns and body, and to determine if ovulation had occurred. Endometrial biopsies were also taken on Day 11 post partum to evaluate endometrial histologic characteristics. Lavage had no effect (P>0.05) on diameter of the uterine body or previously gravid uterine horn, presence of fluid in the uterine lumen, or number of mares which had ovulated by Day 11 post partum. Histologic characteristics of the endometrium (height of luminal epithelium, gland depth, relative gland vclume, and inflammatory-cell score) were not affected by treatment (P>0.05). Postpartum uterine lavage did not significantly affect uterine involution by the parameters measured in normal-foaling mares at Day 11 post partum.     

Influence of prenatal photoperiod on postnatal prolactin secretion in red deer (Cervus elaphus).

Plasma prolactin concentrations were higher (P < 0.001) in newborn red deer calves whose mothers had been maintained for the last 14 weeks of gestation in long days (18 h light) (group L, n = 9) than in those whose mothers had been kept over the same period in short days (6 h light) (group S, n = 5). After transfer of all hinds and suckled calves on the day of birth to constant intermediate daylength (12 h light), prolactin concentrations decreased exponentially (P < 0.001) in group L calves, but not in group S, during the first 21 days. Thereafter, prolactin fell to a nadir in group L calves and rose to peak values in group S calves at 8-12 weeks post partum (P = 0.003), before converging again by 14 weeks. The pattern of prolactin secretion over the first 14 weeks of life was therefore significantly affected by prenatal photoperiod. Plasma prolactin concentrations in the adult hinds were higher (P < 0.001) in group L than group S at 4-10 weeks before parturition; they were similarly high around parturition and fell thereafter to baseline values after 7 weeks. These results provide evidence that deer fetuses respond to photoperiodic information, thereby acquiring a photoperiodic history in utero that influences postnatal responses to photoperiod.     

Maternal and neonatal outcome in pregnancies with no risk factors.

Between November 1979 and April 1984, 790 consecutive pregnant women who considered themselves as having a "normal" pregnancy were followed in private practice from 9 weeks'' gestation until 6 weeks post partum. The women had no pre-existing disease or problem classified as a risk to the pregnancy at the time of their first visit, had a singleton pregnancy and gave birth at Notre-Dame Hospital, Montreal. Maternal complications occurred during the course of pregnancy in 181 women (23%). Complications were mostly related to obstetric conditions (10%), such as preterm labour, intrauterine growth retardation (IUGR) and antepartum hemorrhage, or to medical conditions (12%), the most prevalent of which was hypertension (77% of medical conditions). Neonatal complications occurred in 183 infants (23%). The corrected perinatal death rate was 2.5 per 1000. Prematurity, IUGR and dysmaturity/postmaturity accounted for nearly half of the complications. Hyperbilirubinemia occurred in 7% of the cases. Among women without any maternal complications during pregnancy, the frequency rate of neonatal complications was 19%, compared with 23% among the entire group of 790 women. Our results suggest that the absence of maternal complications does not protect the infant from a neonatal complication. Further refinement is needed to identify markers of obstetric, medical and neonatal complications in pregnancies with no risk factors.     

Separation Anxiety,Attachment and Inter-Personal Representations: Disentangling the Role of Oxytocin in the Perinatal Period

In this paper, we aimed to assess cross-sectionally and longitudinally associations between disturbances in maternal early attachment experiences, symptoms of separation anxiety and depression and oxytocin plasma levels. We examined a mediational model that tested the hypothesis that anxious attachment style arising from the mothers’ early bonding experiences with her own parents was associated with high levels of separation anxiety which, via its impact on depression, was associated with reduced levels of oxytocin in the postnatal period. Data is reported on a structured sample of 127 women recruited during pregnancy from a general hospital antenatal clinic and an initial follow up cohort of 57 women who were re-assessed at 3-months post-partum. We found an association between lower oxytocin level in the post partum period and symptoms of separation anxiety and depression during pregnancy, as well as maternal negative interpersonal representations, upbringing attributes and anxious attachment style. Further meditational analysis revealed that the unique association between anxious attachment and depression is mediated by separation anxiety and that depressed mood mediated the relationship between separation anxiety and oxytocin. In conjunction with evidence from the literature suggesting that lower oxytocin level is associated with bonding difficulties, our findings have significant implications for understanding the biological processes underpinning adverse attachment experiences, negative affect state, and mother-to-infant bonding difficulties.
