Medical outcomes
Maternal and prenatal health is of particular concern among teens who are pregnant or parenting. The worldwide incidence of premature birth and low birth weight is higher among adolescent mothers. Research indicates that pregnant teens are less likely to receive prenatal care, often seeking it in the third trimester, if at all. The Guttmacher Institute reports that one-third of pregnant teens receive insufficient prenatal care and that their children are more likely to suffer from health issues in childhood or be hospitalized than those born to older women. However, studies have indicated that young mothers who are given high-quality maternity care have significantly healthier babies than those that do not. Many of the health-issues associated with teenage mothers, many of whom do not have health insurance, appear to result from lack of access to high-quality medical care. Many pregnant teens are subject to nutritional deficiencies from poor eating habits common in adolescence, including attempts to lose weight through dieting, skipping meals, food faddism, snacking, and consumption of fast food.
Inadequate nutrition during pregnancy is an even more marked problem among teenagers in developing countries. Complications of pregnancy result in the deaths of an estimated 70,000 teen girls in developing countries each year. Young mothers and their babies are also at greater risk of contracting HIV. The World Health Organization estimates that the risk of death following pregnancy is twice as great for women between 15 and 19 years than for those between the ages of 20 and 24. The maternal mortality rate can be up to five times higher for girls aged between 10 and 14 than for women of about twenty years of age. Illegal abortion also holds many risks for teenage girls in areas such as sub-Saharan Africa.
Risks for medical complications are greater for girls 14 years of age and younger, as an underdeveloped pelvis can lead to difficulties in childbirth. Obstructed labour is normally dealt with by Caesarean section in industrialized nations; however, in developing regions where medical services might be unavailable, it can lead to eclampsia, obstetric fistula, infant mortality, or maternal death. For mothers in their late teens, age in itself is not a risk factor, and poor outcomes are associated more with socioeconomic factors rather than with biology.
Socioeconomic and psychological outcomes
Several studies have examined the socioeconomic, medical, and psychological impact of pregnancy and parenthood in teens. Life outcomes for teenage mothers and their children vary; other factors, such as poverty or social support, may be more important than the age of the mother at the birth. Many solutions to counteract the more negative findings have been proposed. Teenage parents who can use family and community support, social services and child-care support to continue their education and get higher paying jobs as they progress with their education.
Impact on the mother
Being a young mother in an industrialized country can affect one's education. Teen mothers are more likely to drop out of high school. Recent studies, though, have found that many of these mothers had already dropped out of school prior to becoming pregnant, but those in school at the time of their pregnancy were as likely to graduate as their peers. One study in 2001 found that women who gave birth during their teens completed secondary-level schooling 10–12% as often and pursued post-secondary education 14–29% as often as women who waited until age 30.
Young motherhood in an industrialized country can affect employment and social class. Less than one third of teenage mothers receive any form of child support, vastly increasing the likelihood of turning to the government for assistance. The correlation between earlier childbearing and failure to complete high school reduces career opportunities for many young women. One study found that, in 1988, 60% of teenage mothers were impoverished at the time of giving birth. Additional research found that nearly 50% of all adolescent mothers sought social assistance within the first five years of their child's life. A study of 100 teenaged mothers in the United Kingdom found that only 11% received a salary, while the remaining 89% were unemployed. Most British teenage mothers live in poverty, with nearly half in the bottom fifth of the income distribution. Teenage women who are pregnant or mothers are seven times more likely to commit suicide than other teenagers. Professor John Ermisch at the institute of social and economic research at Essex University and Dr Roger Ingham, director of the centre of sexual health at Southampton University – found that comparing teenage mothers with other girls with similarly deprived social-economic profiles, bad school experiences and low educational aspirations, the difference in their respective life chances was negligible.
Teenage Motherhood may actually make economic sense for poorer young women, some research suggests. For instance, long-term studies by Duke economist V. Joseph Hotz and colleagues, published in 2005, found that by age 35, former teen moms had earned more in income, paid more in taxes, were substantially less likely to live in poverty and collected less in public assistance than similarly poor women who waited until their 20s to have babies. Women who became mothers in their teens — freed from child-raising duties by their late 20s and early 30s to pursue employment while poorer women who waited to become moms were still stuck at home watching their young children — wound up paying more in taxes than they had collected in welfare. Eight years earlier, the federally commissioned report "Kids Having Kids" also contained a similar finding, though it was buried: "Adolescent childbearers fare slightly better than later-childbearing counterparts in terms of their overall economic welfare."
One-fourth of adolescent mothers will have a second child within 24 months of the first. Factors that determine which mothers are more likely to have a closely-spaced repeat birth include marriage and education: the likelihood decreases with the level of education of the young woman – or her parents – and increases if she gets married.
Impact on the child
Early motherhood can affect the psychosocial development of the infant. The occurrence of developmental disabilities and behavioral issues is increased in children born to teen mothers. One study suggested that adolescent mothers are less likely to stimulate their infant through affectionate behaviors such as touch, smiling, and verbal communication, or to be sensitive and accepting toward his or her needs. Another found that those who had more social support were less likely to show anger toward their children or to rely upon punishment.
Poor academic performance in the children of teenage mothers has also been noted, with many of them being more likely than average to fail to graduate from secondary school, be held back a grade level, or score lower on standardized tests. Daughters born to adolescent parents are more likely to become teen mothers themselves. A son born to a young woman in her teens is three times more likely to serve time in prison.
Impact on other family members
Teen pregnancy and motherhood can influence younger siblings. One study found that the younger sisters of teen mothers were less likely to emphasize the importance of education and employment and more likely to accept human sexual behavior, parenting, and marriage at younger ages; younger brothers, too, were found to be more tolerant of non-marital and early births, in addition to being more susceptible to high-risk behaviors. An additional study discovered that those with an older sibling who is a teen parent often end up babysitting their nieces and nephews and that young girls placed in such a situation have an increased risk of getting pregnant themselves. Social workers play an important role in intervention with families.[citation needed] They work with the families to address common problems and health issues in order to promote a positive outcome for both the family and the baby.
