Pregnancies in the United States by Desire for Pregnancy
We examine whether changes in U.S. pregnancy, birth, and abortion rates between 2009 and 2015 reflect underlying change in the incidence of pregnancies classified by retrospectively reported pregnancy desires: pregnancies reported as having occurred at about the right time, later than wanted, too soon, or not wanted at all, and those for which individuals expressed other feelings, including uncertainty, ambivalence, or indifference. We calculate …
The Impact of Abortion Underreporting on Pregnancy Data and Related Research
Incomplete reporting of pregnancy remains a fundamental shortcoming to the study of US fertility-related experiences. Efforts to improve abortion reporting are needed to strengthen the quality of pregnancy data to support maternal, child, and reproductive health research
Abortion Reporting in the United States
Despite its frequency, abortion remains a highly sensitive, stigmatized, and difficult-to-measure behavior. We present estimates of abortion underreporting for three of the most commonly used national fertility surveys in the United States: the National Survey of Family Growth, the National Longitudinal Survey of Youth 1997, and the National Longitudinal Study of Adolescent to Adult Health. Numbers of abortions reported in each survey were compar…
Contraceptive Failure in the United States
These broad-based declines in failure rates reverse a long-term pattern of minimal change. Future research should explore what lies behind these trends, as well as possibilities for further improvements
Parents' experience of unintended childbearing
The Role of Men's Childbearing Intentions in Father Involvement
An expanding body of research has investigated factors that influence fathers' involvement with their children. Generally overlooked has been the role of pregnancy intentions on men's fathering behaviors. In this study, the authors used nationally representative data from men interviewed in the 2002 and 2006-2010 National Survey of Family Growth to examine relationships between fathers' pregnancy intentions and multiple aspects of their parental …
Are Pregnancy Intentions Associated with Transitions Into and Out of Marriage
The findings should motivate researchers to broaden the scope of research on the consequences of unintended childbearing. Future research should distinguish between mistimed and unwanted births
Pregnancy Intentions, Maternal Behaviors, and Infant Health
The premise that unintended childbearing has significant negative effects on the behavior of mothers and on the health of infants strongly influences public health policy and much of current research on reproductive behaviors. Yet, the evidence base presents mixed findings. Using data from the U.S. National Survey of Family Growth, we employ a measure of pregnancy intentions that incorporates the extent of mistiming, as well as the desire scale d…
Pregnancy Intentions and Maternal and Child Health
Exploring U.S. Men’s Birth Intentions
Variation in State Unintended Pregnancy Rates In the United States
State programs and policies should pay particular attention to increasing support for family planning services for minority groups. Findings also suggest that insurance coverage and receipt of Medicaid among women of reproductive age deserve further exploration as potentially important mechanisms for reducing state unintended pregnancy rates
Unintended Pregnancy Rates at the State Level
These rates provide benchmarks for measuring the impact on unintended pregnancy of state policies and practices, such as those governing sex education and the funding of contraceptive services
The Public Costs of Births Resulting from Unintended Pregnancies
Public insurance programs are central in assisting American families in affording pregnancy and childbirth; however, they pay for a disproportionately high number of births resulting from unintended pregnancy. The resulting budgetary impact warrants increased public efforts to reduce unintended pregnancy
Underreporting of Induced and Spontaneous Abortion in the United States
Underreporting of induced abortions in surveys is widespread, both in countries where the procedure is illegal or highly restricted and in those where it is legal. In this study, we find that fewer than one half of induced abortions performed in the United States in 1997–2001 (47 percent) were reported by women during face‐to‐face interviews in the 2002 National Survey of Family Growth (NSFG). Hispanic and black women and those with low income we…
Predicting Maternal Behaviors During Pregnancy
CONTEXT: Women's behavior during pregnancy, which can affect the health of their infant, may be influenced by their attitude toward the pregnancy. METHODS: Multivariate analyses of data from the 1988 National Maternal and Infant Health Survey and the 1988 National Survey of Family Growth were conducted to investigate whether women with unplanned births differ from other women in their pregnancy behavior, independent of their social and demographi…
The Effects of Pregnancy Planning Status on Birth Outcomes and Infant Care
CONTEXT: The planning status of a pregnancy may affect a woman's prenatal behaviors and the health of her newborn. However, whether this effect is independent or is attributable to socioeconomic and demographic factors has not been explored using nationally representative data. METHODS: Data were obtained on 9,122 births reported in the 1988 National Maternal and Infant Health Survey and 2,548 births reported in the 1988 National Survey of Family…
The Dynamics of Contraceptive Use in Peru
In 1986, the Demographic and Health Surveys project administered the first six-year calendar history of events that included women's contraceptive use and their reasons for discontinuation in experimental surveys in Peru and the Dominican Republic. In this report the experimental survey from Peru is examined to demonstrate how the calendar data can be used to calculate multiple increment-decrement life table rates of contraceptive discontinuation…
Reproductive and socioeconomic determinants of child survival
Studies of infant and child mortality have evolved to distinguish between two sets of explanatory variables-factors related to reproductive or maternal characteristics and socioeconomic factors, generally described as characteristics of the family or household. Almost all multivariate analyses include variables from each of these two sets, but there has been little consideration of the relationship between them. We examine how these two sets of v…
Contraceptive Failure in the United States
This report provides an update of the authors' previous estimates of first-year probabilities of contraceptive failure for all methods of contraception. Estimates are provided of failure during typical use (which includes both incorrect and inconsistent use) and during perfect use (correct use at every act of intercourse). The difference between these two probabilities provides a measure of how forgiving of imperfect use each method is. These rev…
Contraceptive method choice in the Philippines, 1973–83
Contraceptive use and method mix were analysed using Philippines national survey data of 1973, 1978, and 1983. The analyses suggest that the reported decline in contraceptive prevalence between 1978 and 1983 was due to under-reporting of use in 1973 and 1983. The shifts in contraceptive method mix were also partly from under-reporting of rhythm and other methods in 1973 and 1983. Nevertheless, the determinants of method choice were similar in all…
Contraceptive Failure in the United States
The overall goal of this paper is to provide for the first time a comprehensive critical review of the literature on contraceptive failure in developed countries, primarily the United States. The first two sections of our paper lay the groundwork for a critical assessment of the extensive body of studies on this subject, by systematically exploring the concepts and measurement of contraceptive efficacy and the methodological pitfalls that snare m…
