Mental health problems and fear of childbirth: A cohort study of women in an inner-city maternity service.

OBJECTIVES: To estimate the population prevalence of severe fear of childbirth (FOC) during pregnancy and investigate its association with: (a) antenatal common mental disorders (depression and anxiety disorder) and (b) elective cesarean birth. METHODS: 545 participants from an inner-city London maternity population were interviewed soon after their first antenatal appointment (mean gestation: 14 weeks). Current mental disorders were assessed using the Structured Clinical Interview DSM-IV. FOC was measured using the Wijma Delivery Expectancy/Experience Questionnaire (WDEQ-A) at approximately 28 weeks gestation (n = 377), with severe FOC defined using a cutoff of WDEQ-A ≥ 85. Birth mode information was collected at 3 months post-delivery using an adapted Adult Service Use Schedule. Linear regressions were used to model associations, adjusting for the effects of covariates (age, parity, relationship status, education, and planned pregnancy). Sampling weights were used to adjust for bias introduced by the stratified sampling. We also accounted for missing data within the analysis. RESULTS: The estimated population prevalence of severe FOC was 3% (95% CI: 2%-6%) (n = 377). Depression and anxiety were significantly associated with severe FOC after adjustment for covariates (45% vs 11%; coefficient: 15.75, 95% CI: 8.08-23.42, P < .001). There was a weak association between severe FOC and elective cesarean birth. CONCLUSIONS: Severe FOC occurs in around 3% of the population. Depression and anxiety are associated with FOC. Pregnant people with depression and anxiety may be at increased risk of experiencing severe FOC. Attitudes toward childbirth should be assessed as part of routine clinical assessment of pregnant people in contact with mental health services.

Lower Dietary and Circulating Vitamin C in Middle- and Older-Aged Men and Women Are Associated with Lower Estimated Skeletal Muscle Mass.

BACKGROUND: Age-related loss of skeletal muscle mass contributes to poor outcomes including sarcopenia, physical disability, frailty, type 2 diabetes, and mortality. Vitamin C has physiological relevance to skeletal muscle and may protect it during aging, but few studies have investigated its importance in older populations. OBJECTIVES: We aimed to investigate cross-sectional associations of dietary and plasma vitamin C with proxy measures of skeletal muscle mass in a large cohort of middle- and older-aged individuals. METHODS: We analyzed data from >13,000 men and women in the European Prospective Investigation into Cancer and Nutrition-Norfolk cohort, aged 42-82 y. Fat-free mass (FFM), as a proxy for skeletal muscle mass, was estimated using bioelectrical impedance analysis and expressed as a percentage of total mass (FFM%) or standardized by BMI (FFMBMI). Dietary vitamin C intakes were calculated from 7-d food diary data, and plasma vitamin C was measured in peripheral blood. Multivariable regression models, including relevant lifestyle, dietary, and biological covariates, were used to determine associations between FFM measures and quintiles of dietary vitamin C or insufficient compared with sufficient plasma vitamin C (<50 µmol/L and ≥50 µmol/L). RESULTS: Positive trends were found across quintiles of dietary vitamin C and FFM measures for both sexes, with interquintile differences in FFM% and FFMBMI of 1.0% and 2.3% for men and 1.9% and 2.9% for women, respectively (all P < 0.001). Similarly, FFM% and FFMBMI measures were higher in participants with sufficient than with insufficient plasma vitamin C: by 1.6% and 2.0% in men, and 3.4% and 3.9% in women, respectively (all P < 0.001). Associations were also evident in analyses stratified into <65-y and ≥65-y age groups. CONCLUSIONS: Our findings of positive associations, of both dietary and circulating vitamin C with measures of skeletal muscle mass in middle- and older-aged men and women, suggest that dietary vitamin C intake may be useful for reducing age-related muscle loss.

Teenage mothers.

BACKGROUND: Australia's teenage birth rate has fallen to historic lows, but teenage motherhood still occurs and can be challenging for mother and baby. OBJECTIVE: The aim of this article is to review current evidence on the epidemiology and clinical care of teenage pregnancy and parenting, and provide recommendations around management of these young people in Australia. DISCUSSION: Teenage mothers may have experienced family, sexual, and partner violence, family disruption, and socioeconomic disadvantage. Outcomes on a range of peripartum measures are worse for teenage mothers and their babies. Longer term risks for the mother include depression and rapid repeat pregnancy; for the child, intergenerational teenage parenthood; and for both, socioeconomic disadvantage. Teenage motherhood occurs more often within communities where poverty, Aboriginal and Torres Strait Islander status and rural/remote location intersect. General practitioners play a critical role in identification of at-risk teens, preventing unintended teenage pregnancy, clinical care of pregnant teens, and promoting the health and wellbeing of teenage mothers and their children.

Predictors of sexual intercourse and rapid-repeat pregnancy among teenage mothers: an Australian prospective longitudinal study.

OBJECTIVES: To examine the determinants of pregnancy within 2 years of a teenager giving birth for the first time (rapid-repeat pregnancy [RRP]) and resumption of sexual intercourse after the birth. DESIGN, SETTING AND PARTICIPANTS: Prospective cohort study between June 2004 and September 2006 at the sole tertiary obstetric hospital in Western Australia involving teenagers who gave birth for the first time. Data were collected using questionnaires at recruitment, 6 weeks and 3-monthly intervals for up to 2 years postpartum. MAIN OUTCOME MEASURES: RRP and time to a return to sexual intercourse after giving birth. RESULTS: Of the 147 participants, 49 (33%) experienced an RRP. Sexual intercourse was independently significantly associated with using an oral contraceptive (odds ratio [OR], 2.83; 95% CI, 1.38-5.82); living with the birth father (OR, 8.43; 95% CI, 5.12-13.86); intending to become pregnant (OR, 3.20; 95% CI, 1.53-6.65); smoking marijuana (OR, 2.60; 95% CI, 1.38-4.79); and using alcohol (OR, 1.93; 95% CI, 1.17-3.20). Use of long-acting contraceptives was associated with reduced odds of RRP (OR, 0.27; 95% CI, 0.12-0.62), while teenagers who used an oral contraceptive had a similar risk of RRP compared with those using barrier methods or no contraception. Other factors predicting RRP were: being sexually active for more than 3 months (OR, 8.96; 95% CI, 1.97-40.74); intending to become pregnant (OR, 2.39; 95% CI, 1.62-4.93); and being an Indigenous Australian (OR, 2.38; 95% CI, 1.38-4.11). CONCLUSION: There are two options available to health care providers for reducing the rate of RRP: to facilitate teenage mothers' access to long-acting contraceptives; and to gain clear understanding of their intention with regard to repeat pregnancy and to provide appropriate support.

Implanon as a contraceptive choice for teenage mothers: a comparison of contraceptive choices, acceptability and repeat pregnancy.

BACKGROUND: This study was conducted to compare the incidence of repeat teenage pregnancy over a 24-month period postpartum among users of Implanon, the combined oral contraceptive pill (COCP) or depot medroxyprogesterone acetate (DMPA) and barrier methods or nothing (barrier/none). Contraceptive continuation rates 24 months postpartum for Implanon and COCP/DMPA were also compared. STUDY DESIGN: A prospective cohort study was conducted. Comparison groups were postpartum teenagers (12-18 years old) who self-selected Implanon (n=73), COCP/DMPA (n=40) and barrier/none (n=24). Questionnaires were used to gather data at recruitment and postpartum at 6 weeks and then 3 monthly intervals for 2 years. RESULTS: At 24 months postpartum, 48 (35%) teenagers had conceived. Implanon users became pregnant later than other contraceptive groups (p=.022), with mean time to first repeat pregnancy of 23.8 months [95% confidence interval (CI), 22.2-25.5], compared to 18.1 months (95% CI, 15.1-20.7) for COCP/DMPA and 17.6 months (95% CI, 14.0-21.3) for barrier/none. Implanon users were more likely to continue their use at 24 months than COCP/DMPA (p<.001) users. The mean duration for Implanon users was 18.7 months (95% CI, 17.0-20.3) compared to 11.9 months (95% CI, 9.5-14.3) for COCP/DMPA. CONCLUSION: Teenagers who choose Implanon are significantly less likely to become pregnant and were found to continue with this method of contraception 24 months postpartum compared to those who choose COCP or DMPA and barrier methods or nothing.

How do pregnancy outcomes differ in teenage mothers? A Western Australian study.

OBJECTIVES: To determine whether teenage pregnancy and Indigenous status are associated with increased risk of adverse pregnancy outcomes. DESIGN, SETTING AND PARTICIPANTS: A cross-sectional descriptive analysis of nulliparous women with singleton pregnancies who delivered at the sole tertiary obstetric hospital in Western Australia between June 2004 and September 2006, using data obtained from computerised midwifery records. MAIN OUTCOME MEASURES: Maternal risk factors, pregnancy characteristics, and obstetric and perinatal outcomes for teenage and adult pregnancies. RESULTS: Of the 4896 births reviewed, 560 (11%) were to teenage mothers. Teenagers were more likely to be Indigenous and to experience maternal risk factors such as anaemia and smoking. Indigenous women were more likely than non-Indigenous women to be smokers, with young Indigenous teenagers (aged 12-16 years) being most likely to smoke (odds ratio [OR], 6.29; 95% CI, 3.99-9.92). Perinatal outcomes for teenage and adult births were similar, while adjustment for smoking and Indigenous status changed the observed association for the Indigenous population of preterm delivery < 37 weeks' gestation (OR, 1.31; 95% CI, 1.01-1.71), admission to special care nursery (OR, 1.41; 95% CI, 1.10-1.81) and low birthweight (OR, 1.43; 95% CI, 1.10-1.87). However, older teenagers (aged 17-18 years) were the group at highest risk of stillbirth (OR, 1.99; 95% CI, 1.03-3.76). CONCLUSIONS: These results improve our understanding of the obstetric and medical issues associated with teenage pregnancy and birth in WA and how we might tailor our approach to care. Indigenous teenagers need special attention, and there is significant scope for public health interventions around anaemia and smoking in this population.
