This paper presents estimates of delayed childbearing and permanent childlessness in the United States and the determinants of those phenomena. The estimates are derived by fitting the Coale-McNeil marriage model to survey data on age at first birth and by letting the parameters of the model depend on covariates. Substantively, the results provide evidence that the low first birth fertility rat...

Statistical analysis of a large and unique longitudinal data-set demonstrates that childbearing after age 35 or 40 is associated with survival and healthy survival among very old Chinese women and men. The association is stronger for women than for men. The estimates are adjusted for a variety of confounding factors: demographic characteristics, family support, social connections, health practi...

This paper aims to identify different potential factors associated with childbearing pattern among the ever-married women in Bangladesh. Childbearing pattern is directly related to fertility level and rapid population growth is the major consequence of more childbearing. Bearing more children affects adversely on social and economic opportunities and produces substantial risks to the health of ...

Using the PEN-3 model, the purpose of this qualitative study was to understand the factors responsible for the childbearing decisions of women living with HIV/AIDS (WLHA) in Lagos, Nigeria. Sixty WLHA who sought care at a teaching hospital in Lagos were recruited to participate in in-depth interviews. The average age of the participants was 30 years, and 48 participants were receiving antiretro...

PURPOSE Women who are pregnant, planning to become pregnant in the influenza season or caring for infant 6-59 months of age are identified as priority groups for influenza vaccination. Vaccination rate is presumed to be low in those women. The purpose of this study was to investigate perceptions of childbearing age women about influenza vaccination. MATERIALS AND METHODS Childbearing age wome...

In addition, economic analysis helps policymakers determine which of several alternative intervention programs provides the most benefits per dollar spent. For example, policymakers may assess the costeffectiveness of prevention versus treatment programs or broad-based versus targeted prevention programs. Focusing on this latter policy issue, suppose that policymakers wish to reduce the number ...

Women in South Africa have had fewer children on average since the 1970s, but the rate of teenage childbearing in South Africa has remained the same, at 54 births per 1,000 women ages 15 to 19.1 Similarly, the proportion of women ages 20 to 50 who experienced a birth before age 20 has declined since 1985 but remains historically high (see Box 1, page 2). Large numbers of young mothers are a cau...

BACKGROUND Adolescent pregnancy and childbearing pose challenges to young women's educational attainment. Studies show that while adolescent childbearing reduces educational attainment, not becoming pregnant and resorting to induced abortion when pregnant increases women's educational levels. This study examined relationships between adolescents' resolution of their first pregnancies and subseq...

Neural tube defects (NTDs) are serious birth defects of the brain (anencephaly) and spine (spina bifida) that affect approximately 3,000 pregnancies each year in the United States. In 1992, the U.S. Public Health Service recommended that all women of childbearing age in the United States capable of becoming pregnant consume 400 microg of folic acid daily to reduce their risk for having a pregna...
