Sociodemographic differences in the occurrence of teenage pregnancies in Finland in 1987-1998: a follow up study

Sexual behaviours and their associated factors among young people in the Dodowa Health and Demographic Surveillance Site (DHDSS) in Ghana

Objective

This paper describes sexual behaviours and their associated factors among young people.

Design

The study design is cross-sectional.

Setting

Dodowa Health and Demographic Surveillance Site (DHDSS) in Ghana's Shai-Osudoku and Ningo Prampram districts.

Participants

Young people aged 10 to 24 years, median age 17 years.

Outcome measures

Self-reported to have ever had sex, non-use of a condom at last sex, and ever been pregnant or gotten someone pregnant.

Results

Of the 1689 young people; 42% reported having ever had sex, not using a condom at last sexual activity (64%), and ever been pregnant or gotten someone pregnant (41%). The proportion of non-use of condoms at last sex was high across all age groups but was highest (93%) in a small proportion of 10 to 14-year-olds who have ever had sex. Higher proportions of females than males; were reported to have ever had sex (46%), not using a condom at their last sex (66%) and ever been pregnant or getting someone pregnant (56%). Age group (20 to 24), females, primary or junior high school, living alone and lower household socio-economic status were risk factors associated with all three outcome measures.

Conclusion

Risky sexual behaviour is high among young people in the Dodowa HDSS. Therefore, interventions that promote safer sexual practices and help young people make timely decisions on their sexual and reproductive health care needs are required.

Prevalence, trend and determinants of adolescent childbearing in Burundi: a multilevel analysis of the 1987 to 2016-17 Burundi Demographic and Health Surveys data

BACKGROUND

Very little is known about factors influencing adolescent childbearing despite an upward trend in adolescent childbearing prevalence in Burundi, and its perceived implications on the rapid population growth and ill-health of young mothers and their babies. To adress this gap, this study aimed to examine the prevalence, trends and determinants of adolescent childbearing in Burundi.

METHODS

Secondary analyses of the 1987, 2010 and 2016-17 Burundi Demographic and Health Surveys (BDHS) data were conducted using STATA. Weighted samples of 731 (1987 BDHS), 2359 (2010 BDHS) and 3859 (2016-17BDHS) adolescent girls aged 15-19 years old were used for descriptive and trend analyses. Both bivariable and multivariable two-level logistic regression analyses were performed to identify the main factors associated with adolescent childbearing using only the 2016-17 BDHS data.

RESULTS

The prevalence of adolescent childbearing increased from 5.9% in 1987 to 8.3% in 2016/17. Factors such as adolescent girls aged 18-19 years old (aOR =5.85, 95% CI: 3.54-9.65, p <  0.001), adolescent illiteracy (aOR = 4.18, 95% CI: 1.88-9.30, p <  0.001), living in poor communities (aOR = 2.19, 95% CI: 1.03-4.64, p = 0.042), early marriage (aOR = 9.28, 95% CI: 3.11-27.65, p <  0.001), lack of knowledge of any contraceptive methods (aOR = 5.33, 95% CI: 1.48-19.16, p = 0.010), and non-use of modern contraceptive methods (aOR = 24.48, 95% CI: 9.80-61.14), p <  0.001) were associated with higher odds of adolescent childbearing. While factors such as living in the richest household index (aOR = 0.52, 95% IC: 0.45-0.87, p = 0.00), living in West region (aOR = 0.26, 95%CI: 0.08-0.86, p = 0.027) or in South region (aOR = 0.31, 95% CI: 0.10-0.96, p = 0.041) were associated with lower odds of adolescent childbearing.

CONCLUSION

Our study found an upward trend in adolescent childbearing prevalence and there were significant variations in the odds of adolescent childbearing by some individual and community-level factors. School-and community-based intervention programs aimed at promoting girls' education, improving socioeconomic status, knowledge and utilization of contraceptives and prevention of early marriage among adolescent girls is crucial to reduce adolescent childbearing in Burundi.

Trends in teenage delivery and abortion rates in Estonia over more than two decades: a nationwide register-based study

BACKGROUND

In the last 30 years, Estonia has undergone major socio-economic changes, including profound educational and healthcare reforms. The study aimed to analyse trends in teenage delivery and induced abortion rates among younger and older teens, including Estonians and non-Estonians, and to study trends in repeat teenage pregnancies in more detail.

METHODS

The register-based study included data on 29 818 deliveries (1992-2019) and 25 865 (1996-2019) induced abortions among 15-19-year-old girls. Delivery and abortion rates per 1000 girls were calculated by age group, ethnicity and reproductive history. Poisson regression models were applied to estimate average annual percentage changes in delivery and abortion rates over the whole period and in two sub-periods with change points in the trend in 2007.

RESULTS

The delivery rate decreased by 5.3% per year, from 49.9 in 1992 to 8.4 in 2019; the abortion rate decreased by 6.0% per year, from 42.4 in 1996 to 8.6 in 2019. A faster decline in delivery rates took place among Estonians than non-Estonians, but the opposite trend occurred in abortion rates. Delivery rates for first and repeat pregnancies decreased nearly at the same pace, while abortion rates for repeat pregnancies decreased faster than those for first pregnancies.

CONCLUSIONS

A decreasing trend in teenage births is evident in parallel with society becoming wealthier. A remarkable decline in teenage abortions occurs when young people's rights to safe abortion, contraception, mandatory sexuality education and youth-friendly services are ensured. There always remains a small group of adolescents who repeatedly become pregnant.

Parental age and risk of depression: A nationwide, population-based case-control study

BACKGROUND

The global prevalence of depression has increased in recent decades and so has the average age of parenthood. Younger and older parental age have been associated with several mental disorders in their offspring, but the associations for depression have been inconsistent.

METHODS

This study comprised 37,682 singleton births in Finland from 1987- 2007. The subjects were living in Finland at the end of 2012 and had a depressive disorder recorded in the Care Register for Health Care. We also randomly identified 148,795 controls from the Population Register. When missing obsevations excluded the sample was N_cases=18,708 and N_controls=77,243. The results were adjusted for the parents' psychiatric history, depression history, marital status and place of birth, the mothers' maternal socioeconomic status, smoking during pregnancy and previous births and the children's birth weight.

RESULTS

We found a U-shaped association between offspring depression and the age of both parents. The highest odds of depression occurred when the fathers were aged 50 plus years (adjusted Odds Ratio (ORa) 1.51, 95% CI 1.23-1.86) and the mothers were under 20 (ORa 1.44, 95% CI 1.29-1.60) compared to the reference category of parents aged 25-29 years.

LIMITATIONS

The study was limited to depression diagnosed by specialised health care services and had a relatively short follow-up period. Some data were missing and that could lead to risk estimation biases.

CONCLUSION

Diagnosed depression was higher among the offspring of younger and older parents. The results suggest that the age of the parent is etiologically associated with offspring depression.

Adolescents' narratives of coping with unintended pregnancy in Nairobi's informal settlements

Aim

This study explored adolescent experiences and coping strategies for unintended pregnancy in two informal settlements—Viwandani and Korogocho—in Nairobi, Kenya.

Methods

Forty-nine in-depth-interviews and eight focus group discussions were conducted with male and female adolescents aged 15–19 years from households in two informal settlements. Participants were purposively selected to include adolescents of varying socio-demographic characteristics, including the married and unmarried, and adolescents who had never/ever been pregnant. Data were transcribed, translated verbatim and analyzed thematically.

Results

Adolescents attributed unintended pregnancy to poverty, sexual violence and inconsistent contraceptive use. Lack of parental support and guidance, as well as household conflicts also exposed girls to early sexual debut and risky sexual behavior. Decisions about pregnancy management centered on carrying the pregnancy to term or terminating it. Deciding to terminate a pregnancy was not always straightforward and was motivated by concerns about stigma or shame, and school disruption. Participants reiterated that carrying an unintended pregnancy to term disrupts adolescents’ schooling, with few girls returning to school after childbirth. Upon deciding to carry a pregnancy to term, adolescents used several coping strategies such as relocating from usual residence, hiding until delivery and planning to put up the child for adoption upon delivery.

Conclusions

Early interventions to provide adolescents with comprehensive pregnancy prevention information and to address sexual violence and poverty can prevent unintended pregnancy in adolescents. Efforts to support adolescents to positively cope with unintended pregnancy and facilitate re-entry to school are also warranted.

Early Life Exposures and Risky Sexual Behaviors among Adolescents: A Cross-sectional Study in Ghana

BACKGROUND

Risky sexual behaviors (RSBs) are behaviors that could result in unwanted pregnancies and sexually transmitted infections. These behaviors are often initiated during adolescence, and the frequency of engagement in such behaviors rises with increasing age during the teenage years. It has been asserted that exposures to sexual materials early in life could lead to early sex debut among adolescents.

OBJECTIVE

The objective of this study was to determine the early life exposures contributing to RSBs among basic school pupils in the Twifo Praso District of Ghana.

MATERIALS AND METHODS

A descriptive cross-sectional study was conducted using a structured questionnaire. Three hundred and sixty basic school pupils were selected by simple random sampling technique. Data were analyzed using SPSS version 20.

RESULTS

The study found that 64.4% of the respondents have had sexual intercourse at a mean age of 13.7 years. Respondents from polygamous homes were more likely to engage in earlier sexual debut than those from monogamous home (r = 0.0343, P = 0.003). Furthermore, having a high number of friends who have had sex was associated with an early sexual debut (r = 0.720, P = 0.000).

CONCLUSION

Adolescents are initiating sexual intercourse very early in life and this calls for customized reproductive health promotion activities aimed at minimizing risky sexual behaviors. Further studies on how parent-child sexual communication could delay sexual debut are recommended.

Predictors of teenage pregnancy among girls aged 13-19 years in Uganda: a community based case-control study

BACKGROUND

Teenage pregnancy is a serious public health and social problem, with 95% occurring in developing countries. The aim of the study was to investigate the behavioural, familial and social factors associated with teenage pregnancy among girls aged 13-19 years in Lira District, Uganda.

METHODS

Primary data from a case-control study of teenage girls (aged 13-19 years) in Lira District, Uganda was analysed. A Structured questionnaire was administered using face-to-face interviews to collect data on 495 participants, identified through simple random sampling from 32 villages in two counties in Lira District. Data analyses were done using SPSS Statistics 23 for descriptive, bivariate (i.e. Chi-square tests) and multivariable analyses (i.e. logistics regression) used for determining independent associations.

RESULTS

A total of 495 teenage girls participated in the study, however, final analyses were undertaken for 480 respondents. At bivariable analysis, all variables except alcohol consumption were significantly associated with teenage pregnancy. Among the behavioural factors assessed, multivariable analyses showed that having multiple sexual partners, frequent sex and irregular contraceptive use increased the likelihood of teenage pregnancy. Among familial factors, being married was found to increase the likelihood of teenage pregnancy. Peer pressure, sexual abuse and lack of control over sex was observed to increase the likelihood of teenage pregnancy.

CONCLUSIONS

Demographic, behavioural, familial and social factors are important predictors of teenage pregnancy in Lira District. Interventions focussing on: retaining pregnant and married girls at school, information on sexual and reproductive health of teenage girls, improving access to and information about contraceptive use among teenage girls, improving socio-economic status of households, and law enforcement on sexual abuse among girls may come a long way to improving adolescent sexual and health services in the low-income settings.

Pregnancy and early motherhood among adolescents in five East African countries: a multi-level analysis of risk and protective factors

BACKGROUND

Adolescent pregnancy remains a major challenge in both developed and developing countries. Early and unintended pregnancies among adolescents are associated with several adverse health, educational, social and economic outcomes. The aim of this study was to identify the contextual factors that influence adolescent pregnancy and early motherhood in five East African countries.

METHODS

We use DHS data from five East African countries to examine trends and risk factors associated with adolescent pregnancy. DHS surveys collect detailed information on individual and household characteristics, sexual behavior, contraception, and related reproductive behaviors. Our analysis focuses on a weighted subsample of adolescent's age 15-19 years (Kenya, 5820; Tanzania, 2904; Uganda, 4263; Malawi, 5263; Zambia, 3675). Multilevel logistic regression analysis was used to identify the net effects of individual, household and community level contextual variables on adolescent pregnancy after adjusting for potential confounders.

RESULTS

Adolescent pregnancy and early motherhood is common in the five countries, ranging from 18% among adolescents in Kenya (2014) to 29% in Malawi (2016) and Zambia (2014). Although all five countries experienced a decline in adolescent pregnancy since 1990, the declines have been largely inconsistent. More than half of the adolescent's most recent pregnancies and or births in these countries were unintended. The regression analysis found that educational attainment, age at first sex, household wealth, family structure and exposure to media were significantly associated with adolescent pregnancy in at least one of the five countries after adjusting for socio-demographic factors.

CONCLUSION

The study highlights the importance of considering multi-sectoral approaches to addressing adolescent pregnancy. Broader development programs that have positive impacts on girls educational and employment opportunities may potentially influence their agency and decision-making around if and when to have children. Likewise, policies and programs that promote access to and uptake of adolescent sexual and reproductive health services are required to reduce barriers to the use of adolescent Sexual and Reproductive Health (SRH) services.

Increased risk of premature death following teenage abortion and childbirth-a longitudinal cohort study

Background

Teenage pregnancy is associated with an increased risk of premature death. However, it is not known whether the outcome of pregnancy, i.e. induced abortion or childbirth, affects this risk.

Methods

A Finnish population-based register study involving a cohort of 13 691 nulliparous teenagers who conceived in 1987-89; 6652 of them underwent induced abortion and 7039 delivered. The control group consisted of 41 012 coeval women without teenage pregnancy. Follow-up started at the end of pregnancy and lasted until 6th June 2013.

Results

Women with teenage pregnancy had a higher risk of overall mortality vs. controls (mortality rate ratio [MRR] 1.6, [95% CI 1.4-1.8]) and were more likely to die prematurely as a result of suicide, alcohol-related causes, circulatory diseases and motor vehicle accidents. A low educational level appeared to explain these excess risks, except for suicide (adj. MRR 1.5, [95% CI 1.1-2.0]). After adjusting for confounders, the childbirth group faced lower risks of suicide (adj. MRR 0.5, [95% CI 0.3-0.9]) and dying from injury and poisoning (adj. MRR 0.6, [95% CI 0.4-0.8]) compared with women who had undergone abortion.

Conclusions

A low educational level is associated with the increased risk of premature death among women with a history of teenage pregnancy, except for suicide. Extra efforts should be made to encourage pregnant teenagers to continue education, and to provide psychosocial support to teenagers who undergo induced abortion.

Sociodemographic, sexual, reproductive and relationship characteristics of adolescents having an abortion in Portugal: a homogeneous or a heterogeneous group?

OBJECTIVES

The aims of the study were to describe the sociodemographic, sexual, reproductive and relational characteristics of adolescents having an abortion in Portugal and to explore the differences between three adolescent age groups.

METHODS

We recruited a nationally representative sample of 224 adolescents (<16 years, n =  18; 16-17 years, n =  103; 18-19 years, n =  103) who had an abortion. Data were collected from 16 health care services that provide abortion.

RESULTS

The adolescents were predominantly single, were from non-nuclear families, had low-socioeconomic status and were students. Mean age at first sexual intercourse was 15 years and mean gynaecological age was 5 years. Most had had multiple sexual partners, and for most it was their first pregnancy. At conception, the majority were involved in a long-term romantic relationship, were using contraception but did not identify the contraceptive failure that led to the pregnancy. Significant age group differences were found. Compared with the younger age groups, the 18-19 year age group was more frequently married or living with a partner, had finished school, had attained a higher educational level (as had their partner), intended to go to university, and had a greater number of sexual partners. Compared with the other groups, those under 16 years of age reported earlier age at menarche and at first sexual intercourse, and had a lower gynaecological age.

CONCLUSIONS

Our study characterises the life contexts of Portuguese adolescents who had an abortion. It highlights the need to recognise the heterogeneity of this group according to age. The findings have important implications for the development of age-appropriate guidelines to prevent unplanned pregnancy.

Life history factors, personality and the social clustering of sexual experience in adolescents

Adolescent sexual behaviour may show clustering in neighbourhoods, schools and friendship networks. This study aims to assess how experience with sexual intercourse clusters across the social world of adolescents and whether predictors implicated by life history theory or personality traits can account for its between-individual variation and social patterning. Using data on 2877 adolescents from the Avon Longitudinal Study of Parents and Children, we ran logistic multiple classification models to assess the clustering of sexual experience by approximately 17.5 years in schools, neighbourhoods and friendship networks. We examined how much clustering at particular levels could be accounted for by life history predictors and Big Five personality factors. Sexual experience exhibited substantial clustering in friendship networks, while clustering at the level of schools and neighbourhoods was minimal, suggesting a limited role for socio-ecological influences at those levels. While life history predictors did account for some variation in sexual experience, they did not explain clustering in friendship networks. Personality, especially extraversion, explained about a quarter of friends' similarity. After accounting for life history factors and personality, substantial unexplained similarity among friends remained, which may reflect a tendency to associate with similar individuals or the social transmission of behavioural norms.

Induced abortions and birth outcomes of women with a history of severe psychosocial problems in adolescence

OBJECTIVE

To increase knowledge on the reproductive health of women who have been placed in a residential school, a child welfare facility for adolescents with severe psychosocial problems.

METHODS

All women (n=291) who lived in the Finnish residential schools on the last day of the years 1991, 1996, 2001 and 2006 were included in this study and compared with matched general population controls. Register-based information on induced abortions and births was collected until the end of the year 2011.

RESULTS

Compared to controls, women with a residential school history had more induced abortions. A higher proportion of their births took place when they were teenagers or even minors. They were more often single, smoked significantly more during pregnancy and had a higher risk of having a preterm birth or a baby with a low birth weight.

CONCLUSIONS

The findings have implications for the planning of preventive and supportive interventions that aim to increase the well-being of women with a residential school history and their offspring.

Parental age and the risk of attention-deficit/hyperactivity disorder: a nationwide, population-based cohort study

OBJECTIVE

An increasing number of studies has shown an association between parental age and psychiatric disorders. However, there are inconsistent results regarding whether age at parenthood is associated with attention-deficit/hyperactivity disorder (ADHD). The aim of this study is to examine whether low or advanced parental age is associated with ADHD.

METHOD

In this nested case-control study, we identified 10,409 individuals with ADHD born in Finland during 1991 to 2005 and diagnosed with ADHD between 1995 and 2011, along with 39,125 controls matched on sex, date, and place of birth, from nationwide population-based registers. Conditional logistic regression was used to examine the association between parental age and ADHD in offspring, adjusting for potential confounding due to parental psychiatric history, maternal socioeconomic status, marital status, maternal smoking during pregnancy, number of previous births, and birth weight for gestational age.

RESULTS

Fathers younger than 20 years had a 1.5-fold (odds ratio [OR] = 1.55, 95% CI = 1.11-2.18, p = .01) increased risk of having offspring with ADHD as compared to fathers aged 25 to 29 years. Mothers of the same age group had a 1.4-fold (OR = 1.41, 95% CI = 1.15-1.72, p =.0009) increased risk. Advanced maternal age was inversely associated with ADHD (OR = 0.79, 95% CI = 0.64-0.97, p = .02).

CONCLUSION

ADHD was associated with young fathers or mothers at the time of birth. Health professionals working with young parents should be aware of the increased risk of ADHD in offspring. This will improve early detection; however, for the development of preventive measures and appropriate interventions, more information on the developmental pathways is needed.

Evaluating the social determinants of teenage pregnancy: a temporal analysis using a UK obstetric database from 1950 to 2010

BACKGROUND

Teenage pregnancy is a known social problem which has been previously described using a number of deprivation measures. This study aimed to explore the temporal patterns of teenage pregnancy in Aberdeen, Scotland and to assess the discriminating ability of three measures of socioeconomic status.

METHODS

This was a population-based study from 1950 to 2010, using data from the Aberdeen Maternity Neonatal Databank (AMND). The main outcome variable was conceptions occurring in women aged less than 20 years. This study used two area-based measures, the Scottish Index of Multiple Deprivation (SIMD) and the Carstairs index, and one individual-based measure the Social Class based on Occupation (SCO). These measures were compared for their association with teenage conceptions using logistic regression models. The models were used to determine receiver operating characteristic (ROC) curves showing the discriminating ability of the measures.

RESULTS

There was an overall decline in teenage conceptions over the 60-year period, but an increase in the rate ratio for deprived areas. All the measures of socioeconomic status were highly associated with teenage pregnancy. The adjusted OR of SIMD and teenage conception was 5.72 (95% CI 4.62 to 7.09), which compared the most deprived decile with the least deprived decile. The use of ROC curves showed that socioeconomic measures performed better than chance at determining teenage conceptions (χ(2)=21.67, p≤0.0001). They further showed that the SIMD had the largest area under the curve (AUC) with a value of 0.81 (95% CI 0.80 to 0.82), followed by the Carstairs index with an AUC of 0.80 (95% CI 0.78 to 0.80), then by SCO with an AUC of 0.79 (95% CI 0.78 to 0.80).

CONCLUSIONS

Despite a slight decline in teenage pregnancies over the past decades, there is still an evident association between deprivation and teenage pregnancy. This study shows that all the measures of socioeconomic status were highly associated with teenage pregnancy, with the SIMD having the greatest discriminatory effect.

Intergenerational conflicts may help explain parental absence effects on reproductive timing: a model of age at first birth in humans

Background. Parental absences in childhood are often associated with accelerated reproductive maturity in humans. These results are counterintuitive for evolutionary social scientists because reductions in parental investment should be detrimental for offspring, but earlier reproduction is generally associated with higher fitness. In this paper we discuss a neglected hypothesis that early reproduction is often associated with parental absence because it decreases the average relatedness of a developing child to her future siblings. Family members often help each other reproduce, meaning that parents and offspring may find themselves in competition over reproductive opportunities. In these intergenerational negotiations offspring will have less incentive to help the remaining parent rear future half-siblings relative to beginning reproduction themselves.

Method. We illustrate this “intergenerational conflict hypothesis” with a formal game-theoretic model.

Results. We show that when resources constrain reproductive opportunities within the family, parents will generally win reproductive conflicts with their offspring, i.e., they will produce more children of their own and therefore delay existing offsprings’ reproduction. This is due to the asymmetric relatedness between grandparents and grandchildren (r = .25), compared to siblings (r = 0.5), resulting in greater incentives for older siblings to help rear younger siblings than for grandparents to help rear grandchildren. However, if a parent loses or replaces their partner, the conflict between the parent and offspring becomes symmetric since half siblings are as related to one another as grandparents are to grandchildren. This means that the offspring stand to gain more from earlier reproduction when their remaining parent would produce half, rather than full, siblings. We further show that if parents senesce in a way that decreases the quality of their infant relative to their offspring’s infant, the intergenerational conflict can shift to favor the younger generation.

Effect of family background on the educational gradient in lifetime fertility of Finnish women born 1940-50

An inverse association between education and fertility in women has been found in many societies but the causes of this association remain inadequately understood. We investigated whether observed and unobserved family-background characteristics explained educational differences in lifetime fertility among 35,212 Finnish women born in 1940-50. Poisson and logistic regression models, adjusted for measured socio-demographic family-background characteristics and for unobserved family characteristics shared by siblings, were used to analyse the relationship between education and the number of children, having any children, and fertility beyond the first child. The woman's education and the socio-economic position of the family were negatively associated with fertility. Observed family characteristics moderately (3-28 per cent) explained the association between education and fertility, and results from models including unobserved characteristics supported this interpretation. The remaining association may represent a causal relationship between education and fertility or joint preferences that form independently of our measures of background.

Social inequalities in teenage fertility outcomes: childbearing and abortion trends of three birth cohorts in Finland

CONTEXT

Teenagers of low socioeconomic status are more likely to get pregnant, and less likely to choose abortion, than more privileged teenagers. Few studies have used longitudinal data to examine whether these differences persist as overall teenage pregnancy rates decline.

METHODS

Nationally representative register data from 259,242 Finnish women in three birth cohorts (1955-1959, 1965-1969 and 1975-1979) were analyzed using Cox regression to assess socioeconomic differences in teenagers' risks of pregnancy and abortion. Binary logistic regression was used to assess socioeconomic differences in the odds of pregnant teenagers' choosing abortion.

RESULTS

Socioeconomic differences in abortion risk did not change substantially across cohorts; however, differences in the risk of childbirth rose between the first two cohorts and then returned to their earlier level. In all cohorts, teenagers from upper-level employee backgrounds, the most privileged group, had the lowest risks of abortion and childbirth (44-53% and 53-69% lower, respectively, than those for manual workers' children). Teenagers whose parents were lower-level employees or farmers also had reduced risks of both outcomes in all cohorts; results for other socioeconomic groups were less consistent. Pregnant teenagers from upper-level employee backgrounds had 2-3 times the odds of abortion of manual workers' children; the largest difference was found in the 1950s cohort.

CONCLUSIONS

Despite the declining overall teenage pregnancy rate, poorer background continues to be associated with a higher risk of conceiving and of giving birth.

Is teenage pregnancy an obstetric risk in a welfare society? A population-based study in Finland, from 2006 to 2011

OBJECTIVE

To assess obstetric outcomes in teenage pregnancies in a country with a low teenage delivery rate and comprehensive high-quality prenatal care.

DESIGN

Retrospective population-based register study.

SETTING

Finland.

PARTICIPANTS

All nulliparous teenagers (13-15 years (n=84), 16-17 years (n=1234), 18-19 years (n=5987)) and controls (25-year-old to 29-year-old women (n=51 142)) with singleton deliveries in 2006-2011.

MAIN OUTCOME MEASURES

Risk of adverse obstetric outcomes adjusted for demographic factors and clinically relevant pregnancy complications, with main focus on maternal pregnancy complications.

RESULTS

Teenage mothers were more likely than controls to live in rural areas (16% (n=1168) vs 11.8% (n=6035)), smoke (36.4% (n=2661) vs 7% (n=3580)) and misuse alcohol or drugs (1.1% (n=82) vs 0.2% (n=96); p<0.001 for all). Teenagers made a good mean number of antenatal clinic visits (16.4 vs 16.5), but were more likely to have attended fewer than half of the recommended visits (3% (n=210) vs 1.4% (n=716)). Teenagers faced increased risks of several obstetric complications, for example, anaemia (adjusted OR 1.8, 95% CI 1.6 to 2.1), proteinuria (1.8, 1.2 to 2.6), urinary tract infection (UTI; 2.9, 1.8 to 4.8), pyelonephritis (6.3, 3.8 to 10.4) and eclampsia (3.2, 1.4 to 7.3), the risks increasing with descending age for most outcomes. Elevated risks of pre-eclampsia (3.7, 1.5 to 9.0) and preterm delivery (2.5, 1.2 to 5.3) were also found among 13-year-olds to 15-year-olds. However, teenage mothers were more likely to have vaginal delivery (1.9, 1.7 to 2.0) without complications. Inadequate prenatal care among teenagers was a risk factor of eclampsia (12.6, 2.6 to 62.6), UTI (5.8, 1.7 to 19.7) and adverse neonatal outcomes.

CONCLUSIONS

Pregnant teenagers tended to be socioeconomically disadvantaged versus controls and faced higher risks of various pregnancy complications. Special attention should be paid to enrolling teenagers into adequate prenatal care in early pregnancy.

Childbearing in adolescence: intergenerational dejà-vu? Evidence from a Brazilian birth cohort

Background

Pregnancy in adolescence tends to repeat over generations. This event has been little studied in middle and low-income societies undergoing a rapid epidemiological transition. To assess this association it is important to adjust for socioeconomic conditions at different points in lifetime. Therefore, the aim of this study is to analyze the independent effect of adolescent childbearing in a generation on its recurrence in the subsequent generation, after adjusting for socioeconomic status at different points in life.

Methods

The study was conducted on a prospective cohort of singleton liveborn females from the city of Ribeirão Preto, Brazil, evaluated in 1978/79, and their daughters assessed in 2002/04. A total of 1059 mother-daughter pairs were evaluated. The women who had their first childbirth before 20 years of age were considered to be adolescent mothers. The risk of childbearing in adolescence for the daughter was modeled as a function of the occurrence of teenage childbearing in her mother, after adjustment for socio-demographic variables in a Poisson regression model.

Results

The rate of childbearing during adolescence was 31.4% in 1978/79 and 17.1% in 2002/04. Among the daughters of the 1st generation adolescent mothers, this rate was 26.7%, as opposed to 12.7% among the daughters of non adolescent mothers. After adjustments the risk of adolescent childbearing for the 2nd generation was 35% higher for women whose mothers had been pregnant during adolescence – RR = 1.35 (95% CI 1.04-1.74).

Conclusion

Adolescent childbearing in the 1st generation was a predictor of adolescent childbearing in the 2nd, regardless of socioeconomic factors determined at different points in lifetime.

Association between childhood psychosocial factors and induced abortion

OBJECTIVE

To examine the predictive associations between psychosocial risk factors in childhood and having an abortion in adolescence or young adulthood.

STUDY DESIGN

This study is based on a nationwide cohort consisting of 2867 girls born in Finland in 1981. The baseline assessment was conducted at age eight by three informants, and it included information on psychiatric symptoms, school performance and family related risk factors. Register-based follow-up data on abortions were collected until the end of the year when the participants turned 28 years. They were available for 2694 participants. Cox proportional hazards model and logistic regression model were used for statistical analysis.

RESULTS

Altogether 357 women (13.3%) had had an abortion for other than medical reasons during the follow-up. Of the childhood factors, a high level of conduct problems, poor school performance, family structure other than two biological parents, and mother with a low level of education were independently associated with having an abortion. Comparison of the strength of associations between childhood risk factors and first abortion under the age of 20 versus first abortion at a later age, showed no significant differences. Neither did the comparison between one and more abortions.

CONCLUSIONS

At age eight there are already psychosocial factors which predict later abortion. This finding needs to be considered when targeting preventive interventions and developing sexual health services.

Trends in teenage termination of pregnancy and its risk factors: a population-based study in Finland, 1987-2009

STUDY QUESTION

What are the current trends in teenage termination of pregnancy (TOP) and its risk factors?

SUMMARY ANSWER

The incidence of teenage TOP fluctuated substantially during the study period and the incidence of repeat TOP among adolescents increased markedly in the 2000s.

WHAT IS KNOWN ALREADY

Teenage pregnancy is associated with difficulties in psychological, sexual and overall health. The proportion of teenage pregnancies resulting in termination varies by country and time, but only few countries have reliable statistics on TOPs.

STUDY DESIGN, SIZE, DURATION

This nationwide retrospective register study included all the TOPs (n= 52 968) and deliveries (n= 58 882) in Finland between 1987 and 2009 among girls <20 years of age at the beginning of pregnancy.

PARTICIPANTS/MATERIALS, SETTING, METHODS

The cohorts were divided into three subgroups; 13-15- (n= 6087), 16-17- (n= 18 826) and 18-19- (n= 28 055) year-olds.

MAIN RESULTS AND THE ROLE OF CHANCE

After an initial steady decline, the incidence of teenage TOP increased by 44% between 1993 (8.0/1000) and 2003 (11.5/1000), and thereafter declined by 16% until 2009 (9.7/1000). The incidence was higher in older adolescents, but the trends were alike in all age groups. Early TOPs (performed at <56 days of gestation) more than tripled from 11 to 36% during the study period. However, the proportion of second-trimester TOPs remained steady at ≈ 7%. Young age [13-15 years: odds ratio (OR) 1.75 (95% confidence interval (CI) 1.57-1.94), 16-17 years: OR 1.13 (1.05-1.23), 18-19 years: OR 1 (reference category)] and non-use of contraception [(OR 11.16 (10.15-12.27)] were related to a higher risk of second-trimester TOP. The incidence of repeat TOP increased by 95% from 1.9/1000 to 3.7/1000 in 18-19-year-olds and by 120% from 0.5/1000 to 1.1/1000 in 16-17-year-olds between 1993 and 2009. Increasing age [13-15 years: OR 0.16 (95% CI 0.14-0.19), 16-17 years: OR 0.49 (0.45-0.52), 18-19 years 1 (Ref)], living in an urban area [rural: OR 0.62 (0.56-0.67), urban: OR 1 (Ref)] and having undergone a second-trimester TOP [OR 1.46 (1.31-1.63)] were risk factors for repeat TOP. The planned use of intrauterine contraception for post-abortal contraception increased from 2.6 to 6.2% and among girls with repeat TOP from 10 to 19%.

LIMITATIONS

The retrospective nature of the study remains a limitation and the quality of the data is reliant on the accuracy of reporting. We were not able to link repeat TOPs of the same woman in our data set. However, the share of repeat abortions was moderate. WIDER IMPLICATIONS OF THE FINDINGS The rate of teenage TOP seems to rapidly reflect changes in national sexual and reproductive health services and policy. The rising rate of repeat TOP is alarming and may represent a sign of marginalization among these girls. All efforts to maintain a low rate of teenage pregnancy are welcomed.

Social inequality and young pregnancy: the causal attributions of young parents in London, UK

Although the association between young pregnancy and the socio-economic environment is globally recognised, little is understood about either the processes behind it or how young parents construe this relationship. Twenty-one semi-structured interviews were conducted in four London areas; two 'less deprived' and two 'more deprived' in order to solicit young parent's views. Thematic analysis uncovered three factors indicative of how young parents understand the social gradient in young pregnancy; the parental relationship status (openness and parental control); access to education and career; and acceptance of young pregnancy. It is suggested that differing representations of young parenthood across socio-economic subgroups correspond to differing representations, values and beliefs concerning sexual and reproductive behaviour, education and the social acceptability of young pregnancy. Further work is needed to build up a holistic picture of the influence place has on young people's sexual and reproductive health.

Early-life conditions and age at first pregnancy in British women

There is growing evidence that the reproductive schedules of female mammals can be affected by conditions experienced during early development, with low parental investment leading to accelerated life-history strategies in the offspring. In humans, the relationships between early-life conditions and timing of puberty are well studied, but much less attention has been paid to reproductive behaviour. Here, we investigate associations between early-life conditions and age at first pregnancy (AFP) in a large, longitudinally studied cohort of British women (n = 4553). Low birthweight for gestational age, short duration of breastfeeding, separation from mother in childhood, frequent family residential moves and lack of paternal involvement are all independently associated with earlier first pregnancy. Apart from that of birthweight, the effects are robust to adjustment for family socioeconomic position (SEP) and the cohort member's mother's age at her birth. The association between childhood SEP and AFP is partially mediated by early-life conditions, and the association between early-life conditions and AFP is partially mediated by emotional and behavioural problems in childhood. The overall relationship between early-life adversities and AFP appears to be approximately additive.

Impact of adolescent pregnancy on the future life of young mothers in terms of social, familial, and educational changes

PURPOSE

We analyze the impact of adolescent pregnancy in terms of social, familial, and educational changes during the subsequent years.

METHODS

Study participants included all adolescents delivering at an age of 17 years or less within a time frame of 5 years. A telephone interview was performed by using 16 self-developed questions as well as a well-recognized questionnaire on Life Satisfaction (FLZ(M)-A). Out of these 186 adolescents, 131 (70%) adolescents were available for the study. The adolescents were split in two study subsamples: 0-2.5 years after delivery and 2.5-5 years after delivery.

RESULTS

We found significant differences concerning relationship/partner, education/educational level, employment status, means of subsistence, person in a position of trust, close friends and current contraceptive use. Apart from the domain "leisure time/hobbies" study participants were more satisfied compared with a population reference group of the same age.

CONCLUSION

Our study did not support the common assumption that adolescent pregnancy may be a disadvantage for young women. In our study a considerable number does achieve a higher level of education. Furthermore we have shown that adolescents are more satisfied in certain areas of life compared with a population reference group.

Factors associated with teenage pregnancy in the European Union countries: a systematic review

BACKGROUND

As part of the REPROSTAT2 project, this systematic review aimed to identify factors associated with teenage pregnancy in 25 European Union countries.

METHODS

The search strategy included electronic bibliographic databases (1995 to May 2005), bibliographies of selected articles and requests to all country representatives of the research team for relevant reports and publications. Primary outcome measure was conception. Inclusion criteria were quantitative studies of individual-level factors associated with teenage (13-19 years) pregnancy in EU countries.

RESULTS

Of 4444 studies identified and screened, 20 met the inclusion criteria. Most of the included studies took place in UK and Nordic countries. The well-recognized factors of socioeconomic disadvantage, disrupted family structure and low educational level and aspiration appear consistently associated with teenage pregnancy. However, evidence that access to services in itself is a protective factor remains inconsistent. Although further associations with diverse risk-taking behaviours and lifestyle, sexual health knowledge, attitudes and behaviour are reported, the independent effects of these factors too remain unclear.

CONCLUSIONS

Included studies varied widely in terms of methods and definitions used. This heterogeneity within the studies leaves two outstanding issues. First, we cannot synthesize or generalize key findings as to how all these factors interact with one another and which factors are the most significant. Second, it is not possible to examine potential variation between countries. Future research ensuring comparability and generalizability of results related to teenage sexual health outcomes will help gain insight into the international variation in observed pregnancy rates and better inform interventions.

Adolescent Cluster A personality disorder symptoms, role assumption in the transition to adulthood, and resolution or persistence of symptoms

Cluster A odd or eccentric personality disorder (PD) symptoms may reflect a schizophrenia spectrum biological vulnerability in at least some persons. Consequently, this symptom pattern may have particularly negative effects on the transition from adolescent to adult roles. A general population sample of 200 young adults was assessed on Cluster A PD at mean ages 17 and 22, and subsequently provided detailed narratives about their monthly experiences and behaviors between these two ages. Adolescent Cluster A PD was related to the developmental trajectories of residential, career, financial, romantic, and family formation roles during this period, and trajectories were related to a change in symptoms over this period. Symptoms were associated with early parenthood and less advanced education, but for other developmental outcomes tended to differ for men and women. These gender differences were attributable, in part, to the differential meaning and consequences of early parenthood for men and women.

Teenage parenthood among child welfare clients: a Swedish national cohort study of prevalence and odds

To assess prevalence and odds for teenage parenthood among former child welfare clients, we used national register data for all children born in Sweden 1972-1983 (n=1,178,207), including 49,582 former child welfare clients with varying intervention experiences. Logistic regression models, adjusted for demographic, socio-economic and familial background factors, were used to estimate odds ratios. Among youth who received interventions in adolescence, 16-19% of the girls and 5-6% of the boys became teenage parents, compared to 3% for girls and 0.7% for boys without child welfare experiences. Youths who entered child welfare services in their teens had four- to fivefold adjusted odds for becoming a teenage parent. For other child welfare clients, adjusted odds were mostly twofold. Youth of both sexes who receive child welfare services in adolescence are a high-risk group for teenage parenthood. Child welfare agencies should, as a minimum, provide each individual client youth with access to birth control counselling and contraceptives.

Nationwide Increase of Chlamydia trachomatis Infection in Finland

BACKGROUND

Since 1995, the incidence of Chlamydia trachomatis infection has been increasing in Finland, although there have been no major changes in public sexually transmitted disease (STD) services or screening practice.

OBJECTIVES

The objective was to study whether the change in C. trachomatis incidence is significant and to identify specific risk groups.

METHODS

The incidence rates for all C. trachomatis cases notified by laboratories to the National Infectious Disease Register (NIDR) in Finland in 1995-2000 were calculated by gender, age, and domicile. Data from a sentinel STD surveillance network was used to analyze changes of risk-taking behavior in age groups with the highest C. trachomatis rates.

RESULTS

During the 6-year study period, laboratory surveillance data documented an increase in the incidence rate from 23.4 per 10,000 to 29.2 per 10,000. The increase was most evident among people living in nonurban densely populated areas. Highest increase, 1.37-fold (95% confidence interval [CI], 1.29-1.46) in women and 1.69-fold (CI, 1.47-1.92) in men, occurred in the youngest age group (10-19 years old). In 2000, more women, but not men, in the age group of 10-29 years reported 5 or more annual sex partners (18.8%; CI, 16.3-21.6) than in 1995 (8.3%; CI, 5.7-11.5).

CONCLUSION

National surveillance of C. trachomatis infection based on laboratory notification documented increasing incidence rates, especially among adolescents and young people. This risk group should be a target for screening and educational programs to control the epidemic of C. trachomatis infections.
