Consumption of obesogenic foods in non‐Hispanic black mother–infant dyads
Obesity continues to be a problem in the United States. Of particular concern is the epidemic of early childhood obesity. A significant predictor of child diet is maternal diet, but little is known about this relationship during infancy. This study examined the association between maternal and infant consumption of key food groups from 6 to 18 months using data from the Infant Care, Feeding, and Risk of Obesity Study, a prospective cohort of 217 …

The effect of a conditional cash transfer on HIV incidence in young women in rural South Africa (HPTN 068): A phase 3, randomised controlled trial
BACKGROUND: Cash transfers have been proposed as an intervention to reduce HIV-infection risk for young women in sub-Saharan Africa. However, scarce evidence is available about their effect on reducing HIV acquisition. We aimed to assess the effect of a conditional cash transfer on HIV incidence among young women in rural South Africa. METHODS: We did a phase 3, randomised controlled trial (HPTN 068) in the rural Bushbuckridge subdistrict in Mpum…

Self‐regulatory failure and the perpetration of adolescent dating violence: Examining an alcohol use by gene explanation
Studies report that alcohol use is related to partner violence, but for many, alcohol use does not culminate in violence against partners. Guided by a self-regulatory failure framework, we predicted that alcohol use would be more strongly associated with dating violence perpetration among adolescents with genotypes linked to impulsivity and emotional reactivity. The hypothesis was tested using random coefficient modeling of data from a multi-wave…
Gender-Based Power and Couples’ HIV Risk in Uttar Pradesh and Uttarakhand, North India
CONTEXT: Gender inequality is a long-recognized driver of the HIV epidemic. However, few studies have investigated the association between gender-based power and HIV risk in India, which has the world's third largest HIV epidemic. METHODS: Population-based data collected in 2003 from 3,385 couples residing in Uttar Pradesh and Uttarakhand, North India, were used to examine associations between gender-based power (wife's autonomy and husband's ine…
Preconception Stress, Birth Weight, and Birth Weight Disparities Among US Women
Objectives. We examined the impact of preconception acute and chronic stressors on offspring birth weight and racial/ethnic birth weight disparities. Methods. We included birth weights for singleton live first (n = 3512) and second (n = 1901) births to White, Mexican-origin Latina, other-origin Latina, and Black women reported at wave IV of the National Longitudinal Study of Adolescent Health (2007–2008; ages 24–32 years). We generated factor sco…
Serostatus disclosure to sexual partners among people living with HIV: Examining the roles of partner characteristics and stigma
HIV serostatus disclosure among people living with HIV/AIDS (PLWHA) is an important component of preventing HIV transmission to sexual partners. Due to barriers like stigma, however, many PLWHA do not disclose their serostatus to all sexual partners. This study explored differences in HIV serostatus disclosure based on sexual behavior subgroup (men who have sex with men [MSM]; heterosexual men; and women), characteristics of the sexual relationsh…

Exploring Venue-Associated Risk: A Comparison of Multiple Partnerships and Syphilis Infection Among Women Working at Entertainment and Service Venues
The re-emerging syphilis epidemic in China is documented among sex workers, but little is known about STI risk among the broader group of women who work at entertainment and service venues, many of whom do not self-identify as sex workers. In 2009 in Liuzhou, China, community informants identified venues where people meet sexual partners. Characteristics of a stratified random sample of venues were collected during venue visits. Female staff at 4…

Intergenerational Profiles of Socioeconomic (Dis)advantage and Obesity During the Transition to Adulthood
Investigations of socioeconomic status (SES) and health during the transition to adulthood in the United States are complicated by the later and more varied transitions in residence, employment, schooling, and social roles compared with previous generations. Parental SES is an important influence during adolescence but cannot sufficiently capture the SES of the independent young adult. Typical, single SES indicators based on income or education l…

The Development of Four Types of Adolescent Dating Abuse and Selected Demographic Correlates
This study determined the shape of trajectories from ages 13 to 19 of four types of dating abuse perpetration and examined whether the demographic characteristics of sex, minority status, socioeconomic status, and family structure systematically explained variation in the trajectories. The data are from 5 waves of data collected from 973 adolescents participating in the control group of a randomized trial. The mean trajectory for psychological da…
Sex Differences in the Effects of Neighborhood Socioeconomic Disadvantage and Social Organization on Rural Adolescents' Aggression Trajectories
We determined whether effects of neighborhood socioeconomic disadvantage on trajectories of aggression were moderated or mediated by neighborhood social organization and examined sex differences in neighborhood effects for rural adolescents. We used five waves of survey data collected over 2.5 years linked with neighborhood data from interviews with parents and the US Census. The sample ( N = 5,118) was 50.1% female, 52.0% white and 38.3% African…
Support for provision of early medical abortion by mid-level providers in Bihar and Jharkhand, India
Medical abortion has the potential to increase the number, cadre and geographic distribution of providers offering safe abortion services in India. This study reports on a sample of family planning providers (263 mid-level providers, 54 obstetrician-gynaecologists and 88 general physicians) from a 2004 survey of health facilities and their staff in Bihar and Jharkhand, India. It identified factors associated with mid-level provider interest in tr…
Maternal autonomy is inversely related to child stunting in Andhra Pradesh, India
Child stunting, an outcome of chronic undernutrition, contributes to poor quality of life, morbidity and mortality. In South Asia, the low status of women is thought to be one of the primary determinants of undernutrition across the lifespan. Low female status can result in compromised health outcomes for women, which in turn are related to lower infant birthweight and may affect the quality of infant care and nutrition. Maternal autonomy (define…
Childbearing and family in remarriage
Proportional hazards models are used to test hypotheses about the effect of women’s prior childbearing on the probability of having a birth in remarriage and to analyze the effects of other factors. Results indicate that the number of children at the time of remarriage has no effect on childbearing probabilities, but the age of the youngest child has a significant effect. These findings support the view that having a child is important to confirm…
Effects of body fat on weight concerns, dating, and sexual activity: A longitudinal analysis of Black and White adolescent girls
Using data from a 2-year longitudinal study of 200 Black and White adolescent girls (mean age was 13.8 years at study entry), the authors investigated the implications of differences in body fat for dating and sexual activity and the implications of heterosexual activity for dieting and weight concerns. Among White girls, and Black girls with college-educated mothers, more body fat was associated with a lower probability of dating, even among non…

The Association Between Family Violence and Adolescent Dating Violence Onset: Does it Vary by Race, Socioeconomic Status, and Family Structure
The authors determine if the associations between family violence(corporal punishment, violence against the child with the intention of harm, and witnessing violence between parents) and adolescent dating violence vary by subgroups based on race, socioeconomic status, and family structure. This study is guided by the theoretical propositions of Rowe, Vazsonyi, and Flannery (1994) related to examining subgroup differences and similarities in devel…

Effects of Children on Women's Remarriage Prospects
LIFE table analyses of data for white women from the 1975 Current Population Survey showed that the effects of the number of children women had at divorce on their remarriage probabilities depended on the women's age at divorce. Among women divorcing before age 25, being childless increased the likelihood of remarriage; but among women divorcing at 35 or older, having no children decreased it. For women divorcing at age 25 to 34, there was no eff…

Characteristics of maternal employment during pregnancy: Effects on low birthweight
BACKGROUND: Although maternal employment is considered a risk factor for low birthweight (LBW), the manner in which employment might affect birthweight is poorly understood. In this analysis, selected characteristics of employment during pregnancy were examined for effects on pregnancy outcomes. METHODS: Work characteristics included the number of hours per week, physical activities, and environmental conditions. The outcomes of interest were fet…

The multistate life table method: An application to contraceptive switching behavior
In many demographic behaviors (e.g., those relating to marriage, contraception, migration, and health), people change among multiple statuses through time, sometimes leaving and then returning to the same status. Data on such behaviors are often collected in surveys as censored event histories. The multistate life table (MSLT) can be used to properly describe, in a single analysis, these complex transitions among multiple states measured in such …
Effects of repeated questionnaire administration in longitudinal studies of adolescent males' sexual behavior
By comparing four similar groups of young adolescent males who completed questionnaires about their sexual behavior different numbers of times at various intervals, we explore the hypothesis that repeated questionnaire completion will affect sexual behavior. We find little support for the hypothesis even when the number of questionnaire administrations is very high
The Completion of Childbearing: Change and Variation in Timing
Using data on fertility histories from the 1980 US Current Population Survey which included about 77000 households in a national probability sample the timing of the completion of childbearing (as measured by the age of the mother at her final birth) of successive 20th-Century cohorts of US women (born in 1906-15 1916-25 1926-30 and 1931-35) investigated. Data from the National Survey of Family Growth (NSFG) were also used to examine the likely a…

The study seeks to increase understanding of variation in the patterning of life-course events and in the structure of families in remarriage by examining the outcomes of these new marriages for us women. It analyzes the probabilities and the timing of having a birth in a 2nd marriage or of ending the marriage without having a child among women still childless at remarriage and those who already have 1 or more children. By comparing these 2 group…
Estimates of fecundability from a truncated distribution of conception times
A population consisting of women who have conceived before a time t ignores all women whose conception time exceeds t. Such a population is considered as a truncated population, and the samples are called truncated samples. Under the assumption that fecundability among women varies according to a Beta distribution (with parameters a and b), the distribution of conception times in a truncated population can be considered as truncated Type I geomet…

Increment-decrement tables for human reproduction
This paper illustrates the application of increment—decrement life table methods to the study of family building patterns among women. Here age at the oocurrence of a specified birth is considered the principal duration variable. Data from a sample of currently married women from the 1965 US National Fertility Study were used to illustrate the method.

Effect of infant mortality on subsequent fertility of women in jordan: A life table analysis
The proportional hazards models of birth intervals based on the data from the 1976 Jordan Fertility Survey indicate that in Jordan the influence of infant death on subsequent fertility is not uniform among all population subgroups. Child survival seems to have only minimal influence on fertility among less educated women and women at low birth orders. In contrast, the probability of a subsequent birth increases significantly following an infant d…

Maternal Age at Last Birth in Egypt
A proportional hazards regression model was applied to data on women aged 45–49 from the Egyptian Fertility Survey, to assess the effects of women's education, residence, and marital experience on their age at the birth of their last child. When age at marriage and parity were controlled, well-educated urban women tended to stop reproducing earlier than less educated rural women. Compared to intact first marriages, marital dissolution (divorce, w…

Age at last birth and its components
This paper examines the ways in which the behavior of twentieth century cohorts of American women changed simultaneously in the three components of fertility that determine age at last birth—age at first birth, spacing between subsequent births, and parity progression ratios of subsequent births—to produce changes in the timing of the completion of childbearing. It decomposes changes in the mean age at last birth among cohorts and between whites …
Testosterone and pubertal development as predictors of sexual activity: A panel analysis of adolescent males
Strong cross-sectional relationships between testosterone (T) and sexual activity have been found for human adolescent males, even when level of pubertal development is controlled; however, it has not been demonstrated that sexual behavior increases over time as a consequence of hormonal changes. The purpose of this paper was to extend previous cross-sectional findings by demonstrating that sexual behavior is initiated and increases within indivi…
Relationships between aggression and pubertal increases in testosterone: A panel analysis of adolescent males
Existing data linking testosterone (T) and aggression in human adult males are surprisingly tenuous. In one of the few studies based on adolescent males, Olweus et al. (1988) demonstrated strong relationships between concurrent measures of T and aggression. However, the conclusions that could be drawn regarding developmental change were limited. Using data from a three-year panel study of 100 adolescent males (ages 12 to 13 at study entry), we ex…
Testosterone and religiosity as predictors of sexual attitudes and activity among adolescent males: A biosocial model
A biosocial model of the effects of early adolescent testosterone levels and religiosity on adolescent males' sexual attitudes and activity over a 3-year period was examined. Using panel data for approximately 100 boys who were 12·5/13·0 years old at study entry, significant additive effects of free testosterone and frequency of attendance at religious services were demonstrated on the transition to first intercourse and other aspects of sexual b…
