1.	Alcohol Use Trajectories in Two Cohorts of U.S. Women Aged 50 to 65 at Baseline Journal of the American Geriatrics Society 58,12 (December 2010): 2375-2380. Also: http://onlinelibrary.wiley.com/doi/10.1111/j.1532-5415.2010.03180.x/abstract Cohort(s): Mature Women Publisher: Blackwell Publishing, Inc. => Wiley Online Keyword(s): Alcohol Use; Health and Retirement Study (HRS); Women To examine drinking trajectories followed by two cohorts of older women over 8 to 10 years of follow-up. Longitudinal analyses of two nationally representative cohorts using semiparametric group-based models weighted and adjusted for baseline age. Study data were obtained from detailed interviews conducted in the home or by telephone. One cohort included 5,231 women in the Health and Retirement Study (HRS) aged 50 to 65 in 1996; the other included 1,658 women in the National Longitudinal Survey (NLS) aged 50 to 65 in 1995. Both cohorts reported any recent drinking and average number of drinks per drinking day using similar but not identical questions. HRS women completed six interviews (one every other year) from 1996 to 2006. NLS women completed five interviews from 1995 to 2003. All trajectory models yielded similar results. For HRS women, four trajectory groups were observed in the model based on drinks per day: increasing drinkers (4.9% of cohort), infrequent and nondrinkers (61.8%), consistent drinkers (25.9%), and decreasing drinkers (7.4%). Corresponding NLS values from the drinks per day model were 8.8%, 61.4%, 21.2%, and 8.6%, respectively. In 2006, the average number of drinks per day for HRS women in the increasing drinker and consistent drinker trajectories was 1.31 and 1.59, respectively. In 2003, these values for NLS women were 0.99 and 1.38, respectively. Most women do not markedly change their drinking behavior after age 50, but some increase their alcohol use substantially, whereas others continue to exceed current recommendations. These findings underscore the importance of periodically asking older women about their drinking to assess, advise, and assist those who may be at risk for developing alcohol-related problems.

2.	Changes in the Prevalence of Alcohol Use during Pregnancy among Recent and At-Risk Drinkers in the NLSY Cohort Journal of Women's Health 15,9 (November 2006): 1061-1070 Cohort(s): NLSY79 Publisher: Mary Ann Liebert, Inc. Keyword(s): Alcohol Use; Pregnancy and Pregnancy Outcomes Permission to reprint the abstract has not been received from the publisher. Purpose: To support efforts to prevent fetal alcohol syndrome (FAS), population-based data are needed on the prevalence of alcohol use at any time during gestation, particularly among women who were recent and at-risk drinkers. Methods: We used National Longitudinal Survey of Labor Market Experiences in Youth (NLSY) files to estimate the prevalence of any drinking during pregnancy and to evaluate alcohol history risk factors among 6676 births reported by women with prepregnancy drinking data. Prevalence estimates were obtained for 2-year intervals for all 1982–1995 births and for subsets with prepregnancy recent and at-risk drinking. Results: Among all births, drinking during pregnancy declined from 38.3% in 1982–1983 to 23.0% in 1994–1995 ( p < 0.0001). Drinking during pregnancy also declined over time among recent and at-risk drinkers ( p < 0.0001), but the 1994–1995 prevalences were still high (39.3% and 29.0%, respectively). Adjusted logistic models confirmed both the decrease in risk for the later birth years and the persistent heightened risk for births among recent and at-risk drinkers. Conclusions: In addition to ongoing universal prevention strategies that have helped reduce the prevalence of drinking during pregnancy, selective and indicated prevention approaches are needed to encourage abstinence during pregnancy among recent and at-risk drinkers.

3.	Identifying Social Drinkers Likely to Consume Alcohol During Pregnancy: Findings from a Prospective Cohort Study Psychological Reports 101,3 Pt 1 (December 2007): 857-870. Cohort(s): NLSY79 Publisher: Ammons Scientific, Ltd. Keyword(s): Alcohol Use; Pregnancy and Pregnancy Outcomes Permission to reprint the abstract has not been received from the publisher. To prevent fetal alcohol syndrome, some social drinkers who may become pregnant need more than a brief caution, but they can be difficult to detect in clinical settings. National Longitudinal Survey of Youth data from 754 women who completed up to four alcohol history interviews during their college-age years (18-21), and semiparametric group-based models were used to identify groups more likely to drink during a future pregnancy. Two drinking trajectories were observed. About 87% of the women were occasional or nondrinkers during their college-age years; 13% were frequent drinkers. Among first-births to women 22 yr. and older, the adjusted odds ratio for alcohol use during that pregnancy for frequent drinkers versus occasional and nondrinkers was 2.29 (95% confidence interval: 1.25-4.17). This finding suggests women who report frequent drinking during their college-age years may require additional assistance to reduce their risk of drinking during subsequent pregnancies.

Also: http://www.jstor.org/stable/4622482 Cohort(s): NLSY79 Publisher: National Council on Family Relations Keyword(s): Childhood; Childhood Education, Early; Drug Use; Ethnic Differences; Family Characteristics; Family Influences; Life Course; Religion; Religious Influences Using multiply imputed data from 5 waves of the National Longitudinal Survey of Youth (N = 8,294), we investigated whether childhood family characteristics and childhood religious affiliation explain ethnic differences in marijuana and cocaine use in the last year. None of the childhood factors explained ethnic differences in drug use, though ethnicity and several childhood factors had age-specific effects. Over the life course from young adulthood to middle age, ethnic differences in drug use changed and the effect of childhood religious affiliation declined. Having a more intellectually rich family in childhood increased the risk of drug use at younger ages but reduced it at older ages. The study demonstrates the significance of childhood family experiences for understanding adult drug use.

5.	A Life Cycle Model of Fertility and Female Labor Supply with Stochastic Births Ph.D. Dissertation, University of Washington, 1988 Cohort(s): Young Women Publisher: UMI - University Microfilms, Bell and Howell Information and Learning Keyword(s): Child Care; Children; Endogeneity; Fertility; Heterogeneity; Labor Force Participation; Labor Supply; Life Cycle Research; Wages; Women In this paper a lifecycle model of female labor supply and fertility is developed and empirically tested. Both fertility and labor supply are treated as fully endogenous, a factor that distinguishes it from most previous work. Births are treated as stochastic, allowing for unexpected supply shocks and heterogeneity in fecundity. Child quality and care constraints are also included in the model. The formal model is solved using the methods of optimal control. Fewer restrictions are placed on the mother's time allocation in this model. The data used to test the theory presented here were obtained from the Young Women file of the NLS. The empirical results generally provide strong support for the theory that labor supply rises with the wage and declines with the number of children already born. Young children have a larger negative impact on labor supply than older children. Births are negatively related to the wage, number and age of existing children and positively related to the number of months since last birth. Finally, the empirical results provide support for the hypothesis of economies of scale in home care.

6.	Adolescent Fertility and the Educational Attainment of Young Women Report, Seattle WA: Human Affairs Research Center, Battelle Institute, March 1994 Cohort(s): NLSY79 Publisher: Battelle Human Affairs Research Center Keyword(s): Abortion; Adolescent Fertility; Childbearing, Adolescent; Contraception; Discrimination, Sex; Educational Attainment; Endogeneity; Fertility; Hispanics; Pregnancy and Pregnancy Outcomes; Racial Differences This study finds that early childbearing reduces the educational attainment of young women by one to three years. The estimates control for both observed and unobserved differences in background and personal characteristics and take account of the endogeneity of fertility. We use an extensive set of predictors for early fertility, including state and county-level policy variables and other indicators of the costs and availability of abortion and contraception. Adolescent fertility has a strong negative effect on the schooling levels achieved by white, black, and Hispanic women. These results suggest that, if public policies are successful in reducing teenage pregnancy and childbearing, they will also increase the educational attainment of disadvantaged young women and improve their chances for economic self-sufficiency.

8.	How Does Adolescent Fertility Affect the Human Capital and Wages of Young Women? Presented: New Orleans, LA, Population Association of America, May 1996 Cohort(s): NLSY79, Young Women Publisher: Population Association of America Keyword(s): Adolescent Fertility; Childbearing; Childbearing, Adolescent; Education; Educational Returns; Endogeneity; Human Capital; Maternal Employment; Racial Differences; Variables, Instrumental; Wage Dynamics; Wages, Adult; Wages, Young Men; Work Experience Permission to reprint the abstract has not been received from the publisher. We present a model and estimates of the relationship between teenage childbearing and early human capital development, and the resulting consequences for wages in early adulthood. The analysis recognizes that the teenage childbearing decision is endogenous because it is likely to be related to the expected costs of and returns to investing in education teen work experience, and early adult work experience. We use instrumental variables procedures to generate unbiased estimates of the effects of early fertility on education and work experience, and of the effects of all these outcomes on adult wages.

9.	How Does Adolescent Fertility Affect the Human Capital and Wages of Young Women? Discussion Paper No. 1145-97, Institute for Research on Poverty, University of Wisconsin - Madison, September 1997. Also: http://www.irp.wisc.edu/publications/dps/pdfs/dp114597.pdf Cohort(s): NLSY79 Publisher: Institute for Research on Poverty (IRP), University of Wisconsin - Madison Keyword(s): Adolescent Fertility; Childbearing, Adolescent; Economic Well-Being; Education; Human Capital; Maternal Employment; Racial Differences; Variables, Instrumental; Wages, Adult; Wages, Young Women; Work Experience Permission to reprint the abstract has not been received from the publisher. The consequences of teen childbearing for the future well-being of young women remain controversial. In this paper, we model and estimate the relationship between early childbearing and human capital investment, and its effect on wages in early adulthood. Taking advantage of a large set of potential instruments for fertility--principally state- and county-level indicators of the costs of fertility and fertility control--we use instrumental variables procedures to generate unbiased estimates of the effects of early fertility on education and work experience, and the effects of these outcomes on adult wages. For both black and white women, adolescent fertility substantially reduces years of formal education and teenage work experience. White teenage mothers also obtain less early adult work experience than young women who delay childbearing. We also find that, through these human capital effects, teenage childbearing has a significant effect on a young woman's market wage at age 25. Our results, unlike those of recent "revisionist" studies, suggest that public policies that reduce teenage childbearing are likely to have positive effects on the economic well-being of many young mothers and their families.

Instrument Selection: The Case of Teenage Childbearing and Women's Educational Attainment Discussion Paper No. 1077-95, Institute for Research on Poverty, University of Wisconsin - Madison, November 1995.

Recent research has identified situations in which instrumental variables (IV) estimators are severely biased and has suggested diagnostic tests to identify such situations. We suggest a number of alternative techniques for choosing a set of instruments that satisfy these tests from a universe of a priori plausible candidates, and we apply them to a study of the effects of adolescent childbearing on the educational attainment of young women. We find that substantive results are sensitive to instrument choice, and make two recommendations to the practical researcher: First, it is prudent to begin with a large set of potential instruments, when possible, and pare it down through formal testing rather than to rely on a minimal instrument set justified on a priori grounds. Second, the application of more restrictive tests of instrument validity and relevance can yield results very different from those based on less restrictive tests that produce a more inclusive set of instruments, and is the preferred, conservative approach when improper instrument choice can lead to biased estimates.

12.	Teen Childbearing and Human Capital: Does Timing Matter? Working Paper, Center for Public Health Research and Evaluation, Battelle Memorial, Seattle WA, October 1999 Cohort(s): NLSY79 Publisher: Battelle Human Affairs Research Center Keyword(s): Adolescent Fertility; Age at First Birth; Childbearing, Adolescent; Educational Attainment; Human Capital; Racial Differences; Schooling; Teenagers; Variables, Instrumental; Wages; Work Experience In this paper, we model and estimate the relationship between teenage childbearing at different ages and human capital investment. Taking advantage of a large set of potential instruments for fertility--principally state and county-level indicators of the costs of fertility and fertility control--we use instrumental variables procedures to generate unbiased estimates of the effects of early fertility at different ages on education and work. Using data from the NLSY, we find that teenage childbearing at any age substantially reduces years of formal education and early adult work experience for both black and white women. The effects of early and later teen births are similar for both education and early adult work experience. There are no important racial differences in the effects. In contrast, we find no significant impact of a first birth during ages 20-24 on education or work experience. An early teen birth fails have stronger detrimental effects because younger teen mothers are as likely to graduate from high school as older teen mothers, and are equally unlikely to attend college. Our results suggest that "a teen birth is a teen birth", and that public policies that reduce teenage childbearing are likely to have positive effects on the economic well being of many young mothers and their families.
