The Young Mother and the Labor Market

Introduction - The Centro de Orientacao ao Adolescente of Campinas (Southeastern Brazil) maintains a program to qualify economically disadvantaged adolescent students aged 15 to 18 years to enter the labor market. Objective - To understand life projects of teenagers who became mothers while participating in the program, in the period from 2003 to 2008, aiming to find the place of professional life in their life trajectory before and after motherhood. Method - Eight young mothers were interviewed, and a qualitative methodology was applied to the analysis of the interviews. Results - The trajectories of study and work were discontinued or adapted due to motherhood. Four young mothers completed high school and none had entered university. Three did not return to work and the rest had diverse work experiences. The reported difficulties to enter the labor market were: inadequate instruments to support the children's care, low income, lack of work experience, presence of small children and little educational background. Final Considerations - Teenage motherhood did not indicate the exclusion of educational or work projects but indicated adjustments and the need for a family and social support network. It was noted the need for public policies targeted at the inclusion of youths in the labor market and at support services such as nurseries. Also, the need for a change in gender relations was demonstrated, with greater equality of rights as a precondition for the inclusion of women, especially those who are mothers, in the labor market.

A jovem mãe e o mercado de trabalho

INTRODUÇÃO: O Centro de Orientação ao Adolescente de Campinas mantém um programa para capacitar adolescentes de 15 a 18 anos, desfavorecidos economicamente, estudantes, para a entrada no mercado de trabalho. OBJETIVO: Compreender projetos de vida de adolescentes, que se tornaram mães, enquanto participavam do programa, no período de 2003 a 2008, buscando desvelar o lugar da vida profissional na trajetória de vida, antes e depois da maternidade. MÉTODO: Oito jovens mães foram entrevistadas, sendo aplicada metodologia qualitativa para a análise das entrevistas. RESULTADOS: As trajetórias de estudo e trabalho foram descontinuadas, ou sofreram adaptações, com a maternidade. Quatro jovens finalizaram o segundo grau e nenhuma havia ingressado na faculdade. Três não voltaram a trabalhar e as demais tiveram experiências diversificadas de trabalho. As dificuldades relatadas para a inserção no mercado de trabalho foram: insuficiência de instrumentos de apoio no cuidado das crianças, baixo ganho salarial, falta de experiência de trabalho, filhos pequenos e pouca formação educacional. CONSIDERAÇÕES FINAIS: A maternidade na adolescência não indicou a exclusão dos projetos de formação educacional ou de trabalho, mas adaptações e necessidade de uma rede de apoio familiar e social. Constatou-se a necessidade de políticas públicas para a inserção do jovem no mercado de trabalho e para serviços de apoio, como creches. Demonstra-se a necessidade de uma mudança nas relações de gênero, com maior igualdade de direitos, como pré-condição à inserção da mulher no mercado de trabalho, em especial, daquelas que são mães.

Factores asociados a embarazo no deseado en mujeres en edad reproductiva en Colombia 2010

Objetivo: Identificar factores sociodemográficos y de fecundidad, asociados a ocurrencia de embarazo no deseado en mujeres colombianas en edad reproductiva en el año 2010. Métodos: Se realizó estudio retrospectivo de corte transversal, basado en los datos de la ENDS Colombia-2010, del total de mujeres en edad fértil (13-49 años) que al momento de la encuesta se encontraban en embarazo. La variable de interés fue embarazo no deseado, se describió la población a estudio y se evaluó la posible asociación con variables sociodemográficas y de fecundidad, a través de análisis bivariado y multivariado. Se realizaron los mismos análisis por grupo de edad (adolescentes vs adultas). Resultados: La prevalencia de embarazo no deseado en las mujeres colombianas en el 2010 fue de 61,4 %. De acuerdo al modelo de regresión logística, no estar en unión a una pareja (OR: 4,01 IC95%: 3,066-5,269), tener hijos (OR: 2,040 IC95%: 1,581 – 2,631), estar en el quintil de menor riqueza (OR: 2,137 IC95%: 1,328-3,440), y ser adolescente (OR: 1,599 IC95%: 1,183-2,162), son factores que aumentan la probabilidad de tener un embarazo no deseado. Se encontraron diferencias en los factores asociados al realizar segmentación por edad. Conclusiones: La prevalencia de embarazo no deseado permanece alta en Colombia respecto a años anteriores y a otros países. Los resultados pueden ser de utilidad para el desarrollo de políticas en salud sexual y reproductiva teniendo en cuenta los factores asociados identificados priorizando a la población adolescente y de menor estatus socioeconómico, para la prevención de embarazo no deseado en Colombia.

An exploration of knowledge and attitudes related to pre-pregnancy care in women with diabetes

Aims: Pre-pregnancy care optimizes pregnancy outcome in women with pre-gestational diabetes, yet most women enter pregnancy unprepared. We sought to determine knowledge and attitudes of women with Type 1 and Type 2 diabetes of childbearing age towards pre-pregnancy care.

Methods: Twenty-four women (18 with Type 1 diabetes and six with Type 2 diabetes) aged 17–40 years took part in one of four focus group sessions: young nulliparous women with Type 1 diabetes (Group A), older nulliparous women with Type 1 diabetes (Group B), parous women with Type 1 diabetes (Group C) and women with Type 2 diabetes of mixed parity (Group D).

Results: Content analysis of transcribed focus groups revealed that, while women were well informed about the need to plan pregnancy, awareness of the rationale for planning was only evident in parous women or those who had actively sought pre-pregnancy advice. Within each group, there was uncertainty about what pre-pregnancy advice entailed. Despite many women reporting positive healthcare experiences, frequently cited barriers to discussing issues around family planning included unsupportive staff, busy clinics and perceived social stereotypes held by health professionals.

Conclusions: Knowledge and attitudes reported in this study highlight the need for women with diabetes, regardless of age, marital status or type of diabetes, to receive guidance about planning pregnancy in a motivating, positive and supportive manner. The important patient viewpoints expressed in this study may help health professionals determine how best to encourage women to avail of pre-pregnancy care

Preprandial versus postprandial blood glucose monitoring in type 1 diabetic pregnancy: A randomized controlled clinical trial

OBJECTIVE: This study was undertaken to compare preprandial and postprandial capillary glucose monitoring in pregnant women with type 1 diabetes.

Maternal Vitamin D Status in Type 1 Diabetic Pregnancy: Impact on Neonatal Vitamin D Status and Association with Maternal Glycaemic Control

Objective: The first aim of this study was to assess 25-hydroxy vitamin D (25OHD) concentrations in women with type 1 diabetes (T1DM) during pregnancy, post-delivery and also foetal (cord blood) 25OHD concentrations and to examine relationships between these. The second aim of the study was to investigate potential interactions between maternal body mass index (BMI) and foetal vitamin D status. A further study aim was to examine potential relationships between maternal 25OHD and glycosylated haemoglobin (HbA_1c) throughout pregnancy.

Research Design and Methods: This was an observational study of 52 pregnant controls without diabetes and 65 pregnant women with T1DM in a university teaching hospital. Maternal serum 25OHD was measured serially throughout the pregnancy and post-delivery. Cord blood 25OHD was measured at delivery. 25OHD was measured by liquid chromatography tandem mass spectrometry (LC-MS/MS).

Results: Vitamin D deficiency (25OHD <25 nmol/L) was apparent in both the T1DM subjects and controls at all 3 pregnancy trimesters. Vitamin D levels in all cord blood were <50 nmol/L. Maternal 25OHD correlated positively with cord 25OHD at all 3 trimesters in the T1DM group (p= 0.02; p<0.001; p<0.001). 25OHD levels within cord blood were significantly lower for women with diabetes classified as obese vs. normal weight at booking [normal weight BMI <25 kg/m² vs. obese BMI >30 kg/m² (nmol/L±SD); 19.93±11.15 vs. 13.73±4.74, p= 0.026]. In the T1DM group, HbA_1c at booking was significantly negatively correlated with maternal 25OHD at all 3 trimesters (p= 0.004; p = 0.001; p= 0.05).

Conclusion: In T1DM pregnancy, low vitamin D levels persist throughout gestation and post-delivery. Cord blood vitamin D levels correlate with those of the mother, and are significantly lower in obese women than in their normal weight counterparts. Maternal vitamin D levels exhibit a significant negative relationship with HbA_1c levels, supporting a potential role for this vitamin in maintaining glycaemic control. 

Trace elements as predictors of preeclampsia in type 1 diabetic pregnancy

Preeclampsia (PE) affects approximately 5% of all pregnancies, but is increased several-fold in women with pre-gestational type 1 diabetes mellitus (T1DM). Increased oxidative stress and altered maternal plasma trace elements that modulate the antioxidant system have been implicated in PE. In non-diabetic women, increased plasma copper and iron and decreased manganese, selenium, and zinc have been associated with PE in cross-sectional studies. In a longitudinal study, we hypothesized that plasma levels of trace elements differ between T1DM women with vs. without subsequent PE. Samples were collected during the first (gestation 12.2 ± 1.9 weeks, [mean ± SD]), second (21.6 ± 1.5 weeks), and third (31.5 ± 1.7 weeks) trimesters of pregnancy, all before the onset of PE. We compared 23 T1DM women who subsequently developed PE with 24 T1DM women who remained normotensive; and we included 19 non-diabetic (non-DM) normotensive pregnant women as reference controls. Trace elements were measured using inductively coupled plasma mass spectroscopy. In T1DM women with subsequent PE vs normotensive, only plasma zinc was significantly higher at the first trimester, while copper:zinc and copper:high-density lipoprotein cholesterol ratios were higher throughout gestation (all P < .05). These findings persisted after adjustment for covariates. Higher copper:zinc ratios may contribute to oxidative stress in T1DM women who develop PE. Ratios of pro- to anti-oxidant factors may predict risk for PE in diabetic pregnancies more effectively than individual trace element levels.

Contraceptive use and unintended pregnancy among 18-23 year old women in Australia : the first findings of the CUPID study

Objectives: Little is known about young adult women's experience of unintended pregnancy in Australia, nor the extent to which ineffective contraceptive use or contraceptive failure may lead to young women becoming pregnant. The CUPID study is the first in Australia to examine young adult Australian women's patterns of contraceptive use, their experience of unintended pregnancy, and their use (or not) of contraception at the time of conception. Methods: Australian women aged 18-23 years completed an online survey about contraceptive use and experience of unintended pregnancy. They were recruited through a range of methods including advertising on Facebook, and snowball sampling. Sample representativeness was established through comparison with Census data. Results: Of the 511 respondents, 403 women reported that they had ever had sex and were not currently pregnant. Among these women, the pill was the most common method of contraception used on the most recent occasion, used alone (30%) or with condoms (21%). Condoms (alone or with another method other than the pill) were used by a further 17%, and long-acting contraceptive methods by a further 16%. Other methods such as natural methods or partner vasectomy were used by 16%. The withdrawal method was surprisingly common and was mentioned by 15% of the women overall, usually in combination with another method. There were 63 women who had been pregnant, including 5 who were pregnant at the time of the survey, and of these 55 (87%) had become pregnant by accident. Of these 55 women, 69% reported using a range of contraception methods when they became pregnant by accident: Pill only (29%) and in combination with condoms (3%) and withdrawal (5%); condoms only (18%) and in combination with withdrawal (16%); emergency contraceptive pill only (3%) and in combination with withdrawal (3%) and withdrawal only (24%). Conclusions: This study highlighted the use of less effective methods of contraception among young Australian women. The withdrawal method was commonly used, often in combination with other methods, particularly before an unintended pregnancy. Among the women who had been pregnant, most reported that their pregnancy had been unintended. A third of the young women who had experienced an unintended pregnancy were using the withdrawal method. Further research is needed about the place of the withdrawal method in the contraceptive practices of young women.

FP01-5 Pregnancy loss and psychiatric disorders in young men and women : results from Australian longitudinal cohort study

Recent evidence has linked induced abortion with later adverse psychiatric outcomes in young women. Little is known about later adverse psychiatric outcomes in young men whose partners have fallen pregnant and either go on to have a child, have an abortion or miscarry. 1223 women and 1159 men, from an Austrailan cohort born between 1981 and 1984, were assessed at 21 years for psychiatric and substance misuse and lifetime pregnancy histories. Young women reporting a pregnancy loss (either miscarriage or abortion) had nearly three times the odds of experiencing a illicit drug disorder (excluding cannabis), and nearly twice the odds of an alcohol misuse compared to never pregnant women. Young men whose partner had an abortion, but not a miscarriage, had nearly twice the odds of cannabis disorder, illicit drug disorder, and mood disorder compared to men that had never fathered a pregnancy. Young women who have lost a pregnancy have an increased risk of developing alcohol or substance abuse in later life. Young men whose partner aborted a pregnancy only had an increased of substance abuse and mood disorder in later life. These findings add to the growing body of evidence suggesting that pregnancy loss per se increases the risk of a range of substance use disorders in young women. The findings for young men are novel and raise the possibility that the associations measured may be due to common unmeasured factors associated with early pregnancy in young people rather than pregnancy loss.

Uptake of influenza vaccination in pregnancy amongst Australian Aboriginal and Torres Strait Islander women: A mixed-methods pilot study

Background Influenza infection during pregnancy is associated with significant morbidity and mortality. Immunisation against influenza is recommended during pregnancy in several countries but uptake of vaccine is poor. There are limited data on vaccine uptake, and the determinants of vaccination, in Australian Aboriginal and/or Torres Islander women during pregnancy. This study aimed to establish an appropriate methodology and collect pilot data on vaccine uptake and attitudes towards, and perceptions of, maternal influenza vaccination in that population in order to inform the development of larger studies. Methods A mixed-methods study comprised of a cross-sectional survey and yarning circles (focus groups) amongst Aboriginal and Torres Strait Islander women attending two primary health care services. The women were between 28 weeks gestation and less than 16 weeks post-birth. These data were supplemented by data collected in an ongoing national Australian study of maternal influenza vaccination. Aboriginal research officers collected community data and data from the yarning circles which were based on a narrative enquiry framework. Descriptive statistics were used to analyse quantitative data and thematic analyses were applied to qualitative data. Results Quantitative data were available for 53 women and seven of these women participated in the yarning circles. The proportion of women who reported receipt of an influenza vaccine during their pregnancy was 9/53. Less than half of the participants (21/53) reported they had been offered the vaccine in pregnancy. Forty-three percent reported they would get a vaccine if they became pregnant again. Qualitative data suggested perceived benefits to themselves and their infants were important factors in the decision to be vaccinated but there was insufficient information available to women to make that choice. Conclusions The rates of influenza immunisation may continue to remain low for Aboriginal and/or Torres Strait Islander women during pregnancy. Access to services and recommendations by a health care worker may be factors in the lower rates. Our findings support the need for larger studies directed at monitoring and understanding the determinants of maternal influenza vaccine uptake during pregnancy in Australian Aboriginal and Torres Strait Islander women. This research will best be achieved using methods that account for the social and cultural contexts of Aboriginal and Torres Strait Islander communities in Australia.

Serum carotenoids and fat-soluble vitamins in women with type 1 diabetes and preeclampsia:a longitudinal study

Increased oxidative stress and immune dysfunction are implicated in preeclampsia (PE) and may contribute to the two- to fourfold increase in PE prevalence among women with type 1 diabetes. Prospective measures of fat-soluble vitamins in diabetic pregnancy are therefore of interest.

Glycemic targets in the second and third trimester of pregnancy for women with type 1 diabetes

OBJECTIVE: To assess the relationship between second and third trimester glycemic control and adverse outcomes in pregnant women with type 1 diabetes, as uncertainty exists about optimum glycemic targets.

RESEARCH DESIGN AND METHODS: Pregnancy outcomes were assessed prospectively in 725 women with type 1 diabetes from the Diabetes and Pre-eclampsia Intervention Trial. HbA1c (A1C) values at 26 and 34 weeks' gestation were categorized into five groups, the lowest, <6.0% (42 mmol/mol), being the reference. Average pre- and postprandial results from an eight-point capillary glucose profile the previous day were categorized into five groups, the lowest (preprandial <5.0 mmol/L and postprandial <6.0 mmol/L) being the reference.

RESULTS: An A1C of 6.0-6.4% (42-47 mmol/mol) at 26 weeks' gestation was associated with a significantly increased risk of large for gestational age (LGA) (odds ratio 1.7 [95% CI 1.0-3.0]) and an A1C of 6.5-6.9% (48-52 mmol/mol) with a significantly increased risk of preterm delivery (odds ratio 2.5 [95% CI 1.3-4.8]), pre-eclampsia (4.3 [1.7-10.8]), need for a neonatal glucose infusion (2.9 [1.5-5.6]), and a composite adverse outcome (3.2 [1.3-8.0]). These risks increased progressively with increasing A1C. Results were similar at 34 weeks' gestation. Glucose data showed less consistent trends, although the risk of a composite adverse outcome increased with preprandial glucose levels between 6.0 and 6.9 mmol/L at 34 weeks (3.3 [1.3-8.0]).

CONCLUSIONS: LGA increased significantly with an A1C ≥6.0 (42 mmol/mol) at 26 and 34 weeks' gestation and with other adverse outcomes with an A1C ≥6.5% (48 mmol/mol). The data suggest that there is clinical utility in regular measurement of A1C during pregnancy.
