Adipokine levels in overweight women with early-onset gestational diabetes mellitus.

PURPOSE: The study of adipokines in overweight women with early-onset (diagnosed before 20 weeks) gestational diabetes mellitus (GDM) could help to understand the ethiopathological mechanisms of this disorder. Our aim was to assess adipokine levels in overweight pregnant women with early-onset GDM compared to patients with standard-onset (diagnosed at 24-28 weeks) GDM and to glucose-tolerant women at the same gestational ages. METHODS: This nested case-control study included 133 overweight pregnant women: 33 with early-onset (diagnosed < 20 weeks) GDM; 40 with standard-onset (diagnosed ≥ 24 weeks) GDM and 60 glucose-tolerant (normal oral glucose tolerance tests < 20 and ≥ 24 weeks). Adiponectin, leptin, resistin, visfatin and ghrelin serum levels were measured by ELISA. RESULTS: Adiponectin serum levels were significantly lower in early-onset GDM women than in standard-onset GDM patients or controls matched for gestational age. Leptin serum levels were significantly higher in women with early-onset GDM than in controls. Women with early-onset GDM had lower adiponectin/leptin ratio than those with standard-onset GDM. There were no significant differences in resistin, ghrelin and visfatin serum levels among the participants. CONCLUSIONS: Our results suggest that, compared to overweight glucose-tolerant women and patients with standard-onset GDM, overweight women with early-onset GDM have unbalanced adipokine levels, suggesting that they have a more inflammatory profile.

Audit and feedback using the Robson classification to reduce caesarean section rates: a systematic review.

BACKGROUND: In most regions worldwide, caesarean section (CS) rates are increasing. In these settings, new strategies are needed to reduce CS rates. OBJECTIVES: To identify, critically appraise and synthesise studies using the Robson classification as a system to categorise and analyse data in clinical audit cycles to reduce CS rates. SEARCH STRATEGY: Medline, Embase, CINAHL and LILACS were searched from 2001 to 2016. SELECTION CRITERIA: Studies reporting use of the Robson classification to categorise and analyse data in clinical audit cycles to reduce CS rates. DATA COLLECTION: Data on study design, interventions used, CS rates, and perinatal outcomes were extracted. RESULTS: Of 385 citations, 30 were assessed for full text review and six studies, conducted in Brazil, Chile, Italy and Sweden, were included. All studies measured initial CS rates, provided feedback and monitored performance using the Robson classification. In two studies, the audit cycle consisted exclusively of feedback using the Robson classification; the other four used audit and feedback as part of a multifaceted intervention. Baseline CS rates ranged from 20 to 36.8%; after the intervention, CS rates ranged from 3.1 to 21.2%. No studies were randomised or controlled and all had a high risk of bias. CONCLUSION: We identified six studies using the Robson classification within clinical audit cycles to reduce CS rates. All six report reductions in CS rates; however, results should be interpreted with caution because of limited methodological quality. Future trials are needed to evaluate the role of the Robson classification within audit cycles aimed at reducing CS rates. TWEETABLE ABSTRACT: Use of the Robson classification in clinical audit cycles to reduce caesarean rates.

Impact of stillbirths on international comparisons of preterm birth rates: a secondary analysis of the WHO multi-country survey of Maternal and Newborn Health.

OBJECTIVE: To evaluate the extent to which stillbirths affect international comparisons of preterm birth rates in low- and middle-income countries. DESIGN: Secondary analysis of a multi-country cross-sectional study. SETTING: 29 countries participating in the World Health Organization Multicountry Survey on Maternal and Newborn Health. POPULATION: 258 215 singleton deliveries in 286 hospitals. METHODS: We describe how inclusion or exclusion of stillbirth affect rates of preterm births in 29 countries. MAIN OUTCOME MEASURES: Preterm delivery. RESULTS: In all countries, preterm birth rates were substantially lower when based on live births only, than when based on total births. However, the increase in preterm birth rates with inclusion of stillbirths was substantially higher in low Human Development Index (HDI) countries [median 18.2%, interquartile range (17.2-34.6%)] compared with medium (4.3%, 3.0-6.7%), and high-HDI countries (4.8%, 4.4-5.5%). CONCLUSION: Inclusion of stillbirths leads to higher estimates of preterm birth rate in all countries, with a disproportionately large effect in low-HDI countries. Preterm birth rates based on live births alone do not accurately reflect international disparities in perinatal health; thus improved registration and reporting of stillbirths are necessary. TWEETABLE ABSTRACT: Inclusion of stillbirths increases preterm birth rates estimates, especially in low-HDI countries.

Quality of oxytocin available in low- and middle-income countries: a systematic review of the literature.

BACKGROUND: Oxytocin is the drug of choice for preventing and treating postpartum haemorrhage, an important cause of maternal death. Oxytocin is widely available in low and middle-income countries (LMIC) but there are concerns about its quality. OBJECTIVE: To identify, critically appraise and synthesise the findings of studies on the quality of oxytocin available in LMIC. SEARCH STRATEGY: We searched seven electronic databases, without language restriction. SELECTION CRITERIA: Studies reporting results of tests to assess quality of oxytocin samples from LMIC. DATA COLLECTION AND ANALYSIS: Study selection, data extraction and quality assessment were performed in duplicate. Results are presented descriptively. MAIN RESULTS: The search identified 2611 unique citations; eight studies, assessing 559 samples from 15 different countries were included. Most samples were collected from facility level settings (n = 509) and from the private sector (n = 321). The median prevalence of oxytocin samples that failed quality tests was 45.6% (range 0-80%), mostly due to insufficient amounts of active pharmacological ingredient. Over one-third of the samples (n = 204) had low (<90%) oxytocin content indicating substandard medicine; two samples had no active ingredient, suggesting possible counterfeit drugs. The proportion of low fails was higher in samples collected in Africa than in Asia or Latin America (57.5% versus 22.3% versus 0%, respectively, P < 0.0001), in private than in public sectors (34.0% versus 25.3%, P = 0.032) and in facilities than in central distributors (37.9% versus 22.0%, P = 0.030). CONCLUSION: There is a high prevalence of poor-quality oxytocin samples in LMIC countries, mainly due to inadequate amounts of active ingredient. TWEETABLE ABSTRACT: Systematic review points to problems with quality of oxytocin samples from low- and middle-income countries.

Association between rates of caesarean section and maternal and neonatal mortality in the 21st century: a worldwide population-based ecological study with longitudinal data.

OBJECTIVE: Caesarean section was initially performed to save the lives of the mother and/or her baby. Caesarean section rates have risen substantially worldwide over the past decades. In this study, we set out to compile all available caesarean section rates worldwide at the country level, and to identify the appropriate caesarean section rate at the population level associated with the minimal maternal and neonatal mortality. DESIGN: Ecological study using longitudinal data. SETTING: Worldwide country-level data. POPULATION: A total of 159 countries were included in the analyses, representing 98.0% of global live births (2005). METHODS: Nationally representative caesarean section rates from 2000 to 2012 were compiled. We assessed the relationship between caesarean section rates and mortality outcomes, adjusting for socio-economic development by means of human development index (HDI) using fractional polynomial regression models. MAIN OUTCOME MEASURES: Maternal mortality ratio and neonatal mortality rate. RESULTS: Most countries have experienced increases in caesarean section rate during the study period. In the unadjusted analysis, there was a negative association between caesarean section rates and mortality outcomes for low caesarean section rates, especially among the least developed countries. After adjusting for HDI, this effect was much smaller and was only observed below a caesarean section rate of 5-10%. No important association between the caesarean section rate and maternal and neonatal mortality was observed when the caesarean section rate exceeded 10%. CONCLUSIONS: Although caesarean section is an effective intervention to save maternal and infant lives, based on the available ecological evidence, caesarean section rates higher than around 10% at the population level are not associated with decreases in maternal and neonatal mortality rates, and thus may not be necessary to achieve the lowest maternal and neonatal mortality. TWEETABLE ABSTRACT: The caesarean section rate of around 10% may be the optimal rate to achieve the lowest mortality.

Googling caesarean section: a survey on the quality of the information available on the Internet.

OBJECTIVE: To examine the quality and completeness of information on caesarean section in web pages used by laypersons in Brazil, a country with very high rates of caesarean delivery. DESIGN: Cross-sectional study. SETTING: Brazil. SAMPLE: A total of 176 Internet websites. METHODS: The term 'caesarean delivery' and 25 synonyms were entered into the most popular search engines in Brazil. The first three pages of hits were downloaded and assessed by two independent investigators using the DISCERN instrument and a content checklist. MAIN OUTCOME MEASURES: Quality and completeness of information on caesarean section. RESULTS: A total of 3900 web pages were retrieved and 176 fulfilled the selection criteria. The overall average DISCERN score was 43.6 (±8.9 SD), of a maximum score of 75; 30% of the pages were of poor or very poor quality and 47% were of moderate quality. Most pages scored low, especially in questions related to reliability of the information. The most frequently covered topics were: indications for caesarean section (80% of websites), which did not reflect clinical practice; short-term maternal risks (80%); and potential benefits of caesarean section (56%), including maternal and doctor convenience. Less than half of the websites mentioned perinatal risks and less than one-third mentioned long-term maternal risks associated with caesarean section, such as uterine rupture (17%) or placenta praevia/accreta (12%) in future pregnancies. CONCLUSIONS: The quality and completeness of web-based resources in Portuguese about caesarean section were poor to moderate. Pending improvement of these resources, obstetricians should warn pregnant women about these facts and encourage them to discuss what they have read on the Internet about caesarean section. TWEETABLE ABSTRACT: The quality and completeness of information about caesareans is poor in 176 websites used by Brazilians.

What do popular Spanish women's magazines say about caesarean section? A 21-year survey.

OBJECTIVES: Caesarean section (CS) rates are increasing worldwide and maternal request is cited as one of the main reasons for this trend. Women's preferences for route of delivery are influenced by popular media, including magazines. We assessed the information on CS presented in Spanish women's magazines. DESIGN: Systematic review. SETTING: Women's magazines printed from 1989 to 2009 with the largest national distribution. SAMPLE: Articles with any information on CS. METHODS: Articles were selected, read and abstracted in duplicate. Sources of information, scientific accuracy, comprehensiveness and women's testimonials were objectively extracted using a content analysis form designed for this study. MAIN OUTCOME MEASURES: Accuracy, comprehensiveness and sources of information. RESULTS: Most (67%) of the 1223 selected articles presented exclusively personal opinion/birth stories, 12% reported the potential benefits of CS, 26% mentioned the short-term and 10% mentioned the long-term maternal risks, and 6% highlighted the perinatal risks of CS. The most frequent short-term risks were the increased time for maternal recovery (n = 86), frustration/feelings of failure (n = 83) and increased post-surgical pain (n = 71). The most frequently cited long-term risks were uterine rupture (n = 57) and the need for another CS in any subsequent pregnancy (n = 42). Less than 5% of the selected articles reported that CS could increase the risks of infection (n = 53), haemorrhage (n = 31) or placenta praevia/accreta in future pregnancies (n = 6). The sources of information were not reported by 68% of the articles. CONCLUSIONS: The portrayal of CS in Spanish women's magazines is not sufficiently comprehensive and does not provide adequate important information to help the readership to understand the real benefits and risks of this route of delivery.

Maternal and perinatal outcomes among nulliparous adolescents in low- and middle-income countries: a multi-country study.

OBJECTIVE: To investigate the risk of adverse pregnancy outcomes and caesarean section among adolescents in low- and middle-income countries. DESIGN: Secondary analysis using facility-based cross-sectional data from the World Health Organization (WHO) Global Survey on Maternal and Perinatal Health. SETTING: Twenty-three countries in Africa, Latin America, and Asia. POPULATION: Women admitted for delivery in 363 health facilities during 2-3 months between 2004 and 2008. METHODS: We constructed multilevel logistic regression models to estimate the effect of young maternal age on risks of adverse pregnancy outcomes. MAIN OUTCOME MEASURES: Risk of adverse pregnancy outcomes among young mothers. RESULTS: A total of 78 646 nulliparous mothers aged ≤24 years and their singleton infants were included in the analysis. Compared with mothers aged 20-24 years, adolescents aged 16-19 years had a significantly lower risk of caesarean section (adjusted OR 0.75, 95% CI 0.71-0.79). When the analysis was restricted to caesarean section indicated for presumed cephalopelvic disproportion, the risk of caesarean section was significantly higher among mothers aged ≤15 years (aOR 1.27, 95% CI 1.07-1.49) than among those aged 20-24 years. Higher risks of low birthweight and preterm birth were found among adolescents aged 16-19 years (aOR 1.10, 95% CI 1.03-1.17; aOR 1.16, 95% CI 1.09-1.23, respectively) and ≤15 years (aOR 1.33, 95% CI 1.14-1.54; aOR 1.56, 95% CI 1.35-1.80, respectively). CONCLUSIONS: Adolescent girls experiencing pregnancy at a very young age (i.e. <16 years) have an increased risk of adverse pregnancy outcomes.

Premature rupture of membranes before 28 weeks managed expectantly: maternal and perinatal outcomes in a developing country.

This study aimed to assess outcomes of expectant management for early preterm premature rupture of membranes (PPROM). This retrospective cohort involved 66 women with PPROM <28 weeks managed in a single hospital (1999-2006). Main outcomes were chorioamnionitis, severe maternal morbidity (maternal sepsis, haemorrhage/blood transfusion, hysterectomy or admission to intensive care unit), maternal mortality, low birth weight, preterm birth, neonatal infection and perinatal mortality. Mean gestational ages at PPROM and delivery were 21.7 ± 4.2 and 28.4 ± 5.9 weeks, respectively. Chorioamnionitis was diagnosed in 47%; no cases of severe maternal morbidity or mortality occurred. Stillbirth rate was 25.7% and >80% of infants were delivered before 34 weeks. Neonatal infection was diagnosed in 42.9% of the 49 live-births. Overall survival rate was 57.6%. Expectant management of PPROM <28 weeks resulted in high rates of chorioamnionitis and preterm deliveries but in over half of the cases, a live infant was discharged home.

Safety of ultrasonography in pregnancy: WHO systematic review of the literature and meta-analysis.

OBJECTIVE: In the context of the planned International Society of Ultrasound in Obstetrics and Gynecology-World Health Organization multicenter study for the development of fetal growth standards for international application, we conducted a systematic review and meta-analysis to evaluate the safety of human exposure to ultrasonography in pregnancy. METHODS: A systematic search of electronic databases, reference lists and unpublished literature was conducted for trials and observational studies that assessed short- and long-term effects of exposure to ultrasonography, involving women and their fetuses exposed to ultrasonography, using B-mode or Doppler sonography during any period of pregnancy, for any number of times. The outcome measures were: (1) adverse maternal outcome; (2) adverse perinatal outcome; (3) abnormal childhood growth and neurological development; (4) non-right handedness; (5) childhood malignancy; and (6) intellectual performance and mental disease. RESULTS: The electronic search identified 6716 citations, and 19 were identified from secondary sources. A total of 61 publications reporting data from 41 different studies were included: 16 controlled trials, 13 cohort and 12 case-control studies. Ultrasonography in pregnancy was not associated with adverse maternal or perinatal outcome, impaired physical or neurological development, increased risk for malignancy in childhood, subnormal intellectual performance or mental diseases. According to the available clinical trials, there was a weak association between exposure to ultrasonography and non-right handedness in boys (odds ratio 1.26; 95% CI, 1.03-1.54). CONCLUSION: According to the available evidence, exposure to diagnostic ultrasonography during pregnancy appears to be safe.

Prediction of acidemia at birth by Doppler assessment of fetal cerebral transverse sinus in pregnancies with placental insufficiency.

OBJECTIVES: To evaluate the prediction of acidemia at birth using cerebral transverse sinus (CTS) Doppler velocimetry and to determine the best parameter and cut-off values for its prediction in pregnancies complicated with placental insufficiency. METHODS: This was a prospective cross-sectional study involving 69 pregnant women (26-40 weeks' gestation) with placental insufficiency managed in two Brazilian hospitals. Doppler assessment of the CTS was carried out in the last 24 h before delivery, and the peak ventricular systolic (S-wave) and diastolic (D-wave) velocities as well as the atrial systolic velocity (A-wave) were recorded and the pulsatility index for veins (PIV) was calculated. At birth, arterial and venous umbilical cord blood samples were collected to determine acid-base and pH status. A receiver-operating characteristics (ROC) curve was constructed for each Doppler parameter with birth acidemia as the dependent variable. Sensitivity, specificity, positive and negative predictive values, accuracy and false-positive and false-negative rates were calculated for the parameters considered to be good predictors of acidemia. RESULTS: The S, D and A peak velocities and the S/A ratio were not good predictors of acidemia at birth. The PIV and the (S - A)/S ratio were good predictors of acidemia (area under the ROC curve = 0.698 (P = 0.009) and 0.654 (P = 0.009), respectively). The cut-off values were PIV = 0.855 and (S - A)/S = 0.703). CONCLUSIONS: The PIV and the (S - A)/S ratio of the CTS were good predictors of acidemia at birth in this high-risk population with placental insufficiency.

The cross-sectional area of umbilical cord components in normal pregnancy.

OBJECTIVE: To determine the normal cross-sectional areas of the umbilical vein, umbilical artery, and Wharton jelly in healthy pregnancies, and correlate the obtained values with fetal anthropometric parameters. METHODS: A cross-sectional study was performed with 312 women between the 24th and 39th weeks of a normal pregnancy. The cross-sectional areas of umbilical cord vessels were measured at the junction of the cord and fetal abdomen, and the values were subtracted from the total cord cross-sectional area to assess the cross-sectional area of the Wharton jelly. The anthropometric parameters analyzed were biparietal diameter, head circumference, femur length, and estimated fetal weight, and the Spearman correlation was used to assess the correlation between the cross-sectional areas of umbilical cord components and fetal anthropometric parameters. A polynomial regression analysis was performed to identify the curves that best adjusted to mean and standard deviation according to gestational age. RESULTS: A statistically significant correlation was observed between the cross-sectional areas of cord components and fetal anthropometric parameters (P<0.001) as well as gestational age (P<0.001). CONCLUSIONS: Reference measurements of the cross-sectional areas of umbilical cord components are important tools in the assessment of fetal growth.

Chromosomal and cardiac anomalies in fetuses with intracardiac echogenic foci.

OBJECTIVE: To evaluate the prevalence of intracardiac echogenic foci (ICEF) and the association between ICEF and chromosomal and cardiac anomalies in Brazilian women. METHODS: In a cross-sectional observational study, 373 of the 23,360 genetic sonograms performed at a private maternal-fetal medicine clinic over 5 years showed intracardiac echogenic foci (ICEF). These 373 sonograms were reviewed for chromosomal and cardiac anomalies and associations were analyzed using the chi(2) test or the Fisher exact test. P<0.05 was considered significant. RESULTS: The prevalence of ICEF was 1.7%. Cardiac anomalies were detected in 10 sonograms (2.7%) and chromosomal anomalies in 14 (3.7%). There were cardiac defects in 6 (1.7%) of the 359 euploid fetuses with isolated ICEF. Of the 373 women who had fetuses with ICEF, 295 were younger than 35 years and 78 were 35 years or older. There were 6 fetuses (2.1%) with aneuploidy in the younger group and 8 (10.3%) in the older group. CONCLUSION: The prevalence of ICEF was 1.7%, and there was an association between cardiac and chromosomal anomalies. Women carrying fetuses with ICEF should be offered fetal echocardiography and karyotyping.

Pregnancy outcome for Rh-alloimmunized women.

OBJECTIVE: To compare perinatal results of Rh-alloimmunized pregnancies managed with spectrophotometric amniotic fluid analysis or fetal middle cerebral artery Doppler ultrasonographic velocimetry. METHOD: A descriptive observational study involving 291 consecutive Rh-negative pregnancies. Group 1 consisted of 74 isoimmunized women managed with amniotic fluid spectrophotometry; group 2 of 25 isoimmunized women managed with Doppler ultrasonography; and group 3 of 192 nonimmunized Rh-negative women. The variables analyzed were need for intrauterine or neonatal transfusion, mode and time of delivery, birth weight, neonatal hematocrit, and perinatal mortality. RESULTS: Need for intrauterine transfusion, birth weight, prematurity, rate of cesarean section, and perinatal mortality were similar in groups 1 and 2. Neonatal hematocrit was significantly lower and the need for neonatal transfusion was significantly higher when spectrophotometry rather than Doppler ultrasonographic velocimetry was used. CONCLUSION: Fetuses managed with Doppler ultrasonographic velocimetry had a higher hematocrit at birth and a lesser need for neonatal transfusion, suggesting that this noninvasive method of monitoring fetal anemia is a better choice.

Aging of intrauterine tissues in spontaneous preterm birth and preterm premature rupture of the membranes: A systematic review of the literature.

BACKGROUND: Many adverse pregnancy outcomes (APOs), including spontaneous preterm birth (PTB), are associated with placental dysfunction. Recent clinical and experimental evidences suggest that premature aging of the placenta may be involved in these events. Although placental aging is a well-known concept, the mechanisms of aging during normal pregnancy and premature aging in APOs are still unclear. This review was conducted to assess the knowledge on placental aging related biochemical changes leading to placental dysfunction in PTB and/or preterm premature rupture of membranes (pPROM). METHODS: We performed a systematic review of studies published over the last 50 years in two electronic databases (Pubmed and Embase) on placental aging and PTB or pPROM. RESULTS: The search yielded 554 citations, 30 relevant studies were selected for full-text review and three were included in the review. Only one study reported oxidative stress-related aging and degenerative changes in human placental membranes and telomere length reduction in fetal cells as part of PTB and/or pPROM mechanisms. Similarly, two animal studies reported findings of decidual senescence and referred to PTB mechanisms. CONCLUSION: Placental and fetal membrane oxidative damage and telomere reduction are linked to premature aging in PTB and pPROM but the risk factors and biomolecular pathways causing this phenomenon are not established in the literature. However, no biomarkers or clinical indicators of premature aging as a pathology of PTB and pPROM have been reported. We document major knowledge gaps and propose several areas for future research to improve our understanding of premature aging linked to placental dysfunction.

[Prenatal corticoid therapy in hypertensive syndromes of pregnancies and its effects in maternal blood pressure]. / Corticoterapia pré-natal nas síndromes hipertensivas da gestação e seus efeitos na pressão arterial materna.

PURPOSE: To evaluate the behaviour of blood pressure among hypertensive pregnants during glucocorticoid therapy (LIGGINS scheme) in order to accelerate the maturity of fetal lung. METHODS: In a retrospective study, 27 pregnant with a story of hypertensive disorder, between 24 and 34 weeks, during glucocorticoid cycle were avaluated. For this matter, statistical analisis were performed using the means of systolic (SBP) and diastolic blood pressure during the therapy days, on the day before and on the day after. The results were statistically analyzed with F statistic test ( significant if p<005) RESULTS: There was no statistical variance in blood pressure levels, neither in SBP nor in DBP. There was no difficulty in clinical controls and no change in antihypertensive drugs related to glucocorticoid therapy. CONCLUSIONS: Our results show observe the safety of glucocorticoid therapy among pregnant women with hypertensive disorders related to the possible raising of the blood pressure levels.

Aspirin plus calcium supplementation to prevent superimposed preeclampsia: a randomized trial.

Preeclampsia is an important cause of maternal and perinatal morbidity and mortality. Previous studies have tested calcium supplementation and aspirin separately to reduce the incidence of preeclampsia but not the effects of combined supplementation. The objective of this study was to investigate the effectiveness of aspirin combined with calcium supplementation to prevent preeclampsia in women with chronic hypertension. A double-blind, placebo-controlled randomized clinical trial was carried out at the antenatal clinic of a large university hospital in São Paulo, SP, Brazil. A total of 49 women with chronic hypertension and abnormal uterine artery Doppler at 20-27 weeks gestation were randomly assigned to receive placebo (N = 26) or 100 mg aspirin plus 2 g calcium (N = 23) daily until delivery. The main outcome of this pilot study was development of superimposed preeclampsia. Secondary outcomes were fetal growth restriction and preterm birth. The rate of superimposed preeclampsia was 28.6% lower among women receiving aspirin plus calcium than in the placebo group (52.2 vs 73.1%, respectively, P=0.112). The rate of fetal growth restriction was reduced by 80.8% in the supplemented group (25 vs 4.8% in the placebo vs supplemented groups, respectively; P=0.073). The rate of preterm birth was 33.3% in both groups. The combined supplementation of aspirin and calcium starting at 20-27 weeks of gestation produced a nonsignificant decrease in the incidence of superimposed preeclampsia and fetal growth restriction in hypertensive women with abnormal uterine artery Doppler.

Does motherhood affect the quality of life of adolescents?

STUDY OBJECTIVE: Assess the quality of life (QOL) of female adolescents with children compared to those without children. DESIGN: Cross-sectional. SETTING: Public university-affiliated family planning clinic, São Paulo, Brazil. PARTICIPANTS: 91 female adolescents (16-19 years) of low socio-economic status with and without children. INTERVENTIONS: The Portuguese version of the WHOQOL-BREF questionnaire was used. OUTCOME MEASURES: Mean scores of the 4 main domains were compared between adolescents with and without children. RESULTS: Both mothers (N = 40) and nonmothers (N = 51) had low mean scores (<75%) in most of the QOL domains. Compared to adolescents without children, adolescent mothers scored significantly lower in the physical (52.1 vs 59.4, P = .0137) and social (66.9 vs 77.3, P = .0182) domains. CONCLUSION: Adolescent mothers have a significantly lower quality of life in the physical and in the social relationships domains than nonmothers.
