The encounter with family violence and risky sexual activity among young adolescent females

In this article, we analyze the relationship between family violence and risky sexual activity for female adolescents (age 14 to 17). We examine two forms of family violence: experience (receiving physical abuse from a parent or parent-figure) and exposure (witnessing interparental physical violence). We hypothesize that either form of violence will predict greater odds of engaging in risky sexual behavior. We define risky sexual activity as any of the following: having multiple partners within the last 12 months or having sex with partners who are themselves engaging in risky behavior (e.g., having multiple partners of either sex, injecting unprescribed drugs, sharing unprescribed needles for injecting drugs). We analyzed data from 710 respondents taken from the National Survey of Family Growth, Cycle V, living with at least one biological parent. Results showed that experiencing violence from a parent greatly increased the likelihood of risky sex, even when controlling for the experience of forced sex, age, mother's age at first birth, race, socioeconomic status, and religiosity. Female adolescents who had experienced forced sex, those who were older (especially 17-year-olds), non-Hispanic Blacks (but not Hispanics), those living in a family with low educational attainment (less than a high school diploma), and those for whom religion was not or only somewhat personally important were more likely to report risky sex compared to others. These effects were not modified by whether the respondents lived in single- or two-parent families. An interaction between the two forms of physical violence suggests that either form is sufficient to increase significantly the odds of risky sex; an analysis in which respondents were differentiated by their experience of either form of violence showed a strong effect of experience on risky sex, net of the control variables.     

Gastrostomy and children: a review of the literature in learning disabilities

Children with developmental delays often suffer feeding difficulties. It has become common for those with a severe likelihood of malnutrition to be considered for alternative methods of nutritional intake, often a gastrostomy. As part of a pilot study investigating the effects of gastrostomy on the child and their family, we conducted a literature review in order to establish the current areas of research, progress and concern. This paper describes the method and findings of the literature review and concludes with a discussion of the topics raised. The main conclusion is that although the need for gastrostomy in this group of children has been shown to be effective in maintaining adequate weight gain and nutritional intake, the support given to the family prior to, and after the operation is inadequate. Greater emphasis needs to be placed on detailed family assessment as part of the early intervention package. Copyright © 2001 John Wiley & Sons, Ltd.     

Practical usage of O'Brien's OLS and GLS statistics in clinical trials

Multivariate techniques of O'Brien's OLS and GLS statistics are discussed in the context of their application in clinical trials. We introduce the concept of an operational effect size and illustrate its use to evaluate power. An extension describing how to handle covariates and missing data is developed in the context of Mixed models. This extension allowing adjustment for covariates is easily programmed in any statistical package including SAS. Monte Carlo simulation is used for a number of different sample sizes to compare the actual size and power of the tests based on O'Brien's OLS and GLS statistics.     

Parental structure experiences of children: Exposure,transitions, and type at birth

This paper examines parental structure experiences during childhood and adolescence of non-Hispanic whites, blacks, Mexicans, and Puerto Ricans born 1957 to 1964. The study shows that the parental structure types most commonly experienced are mother-father, mother only, and mother-stepfather. The study also finds that a significant proportion of children move into a mother-only family and do not leave it. Finally, the study shows that the parental structure experiences of children are strongly influenced by their parental structure at birth.A version of this paper was presented at the meetings of the American Sociological Association in Pittsburgh, Pennsylvania, August 1992.

The counteracting influences of increased female headship and decreased number of children on inequality in economic well-being by age: 1960 to 1980

This study uses 1960, 1970, and 1980 US Census data to investigate the effects of increased female headship and decreased number of children on economic well-being. The main findings are (1) while increases in female headship lowered economic well-being, decreases in number of children raised economic well-being so that these changes had counteracting effects, and (2) age inequality in economic well-being changed because family composition changes varied in intensity by age group.     

An evaluation of the population and development program in Egypt

Previous rural surveys analyzing the impact of the Egyptian Population and Development Program on KAP variables (knowledge, attitudes, and practices of contraception) have produced mixed results. In 1982 a survey specifically designed to measure program impact contained refinements in questionnaire measurement, sampling, and analysis. Each refinement intensified the apparent program impact. Fertility itself still appears unresponsive, and attitudes toward family size have changed little, but marked differences between program and nonprogram areas in contraceptive knowledge, attitudes, and practice suggest imminent fertility declines in program areas.
