Engaging pregnant and parenting teens: early challenges and lessons learned from the Evaluation of Adolescent Pregnancy Prevention Approaches.

This article draws on data from the ongoing federal Evaluation of Adolescent Pregnancy Prevention Approaches to discuss the early implementation experiences of two new and innovative programs intended to delay rapid repeat pregnancy among teen mothers: (1) AIM 4 Teen Moms, in Los Angeles County, California; and (2) Teen Options to Prevent Pregnancy (T.O.P.

Leadless pacing using induction technology: impact of pulse shape and geometric factors on pacing efficiency.

Aims: Leadless pacing can be done by transmitting energy by an alternating magnetic field from a subcutaneous transmitter unit (TU) to an endocardial receiver unit (RU). Safety and energy consumption are key issues that determine the clinical feasibility of this new technique. The aims of the study were (i) to evaluate the stimulation characteristics of the non-rectangular pacing pulses induced by the alternating magnetic field, (ii) to determine the extent and impact of RU movement caused by the beating heart, and (iii) to evaluate the influence of the relative position between TU and RU on pacing efficiency and energy consumption.

Health disparities in low-income families with infants and toddlers: needs and challenges related to disability.

This study examines disparities in health status, health care utilization, insurance coverage and satisfaction in US low-income parents of infants and toddlers with disabilities compared to low-income parents of children without disabilities. The Early Head Start Research and Evaluation Project is a longitudinal study involving 2087 families in 17 communities across the United States. Families completed interviews at enrollment and at 7, 16, and 28 months after enrollment.

Leadless pacing of the heart using induction technology: a feasibility study.

Objectives: To develop a leadless pacemaker system based on induction technology and to investigate its feasibility and safety in the pig model.

Background: Despite tremendous technical advances during the last decades, cardiac pacing is still associated with a considerable rate of complications that can be primarily attributed to the leads.

Methods: The device consists of a transmitter unit implanted subcutaneously just above the heart and an endocardial receiver unit implanted in the apex of the right ventricle.

The effectiveness of early head start for 3-year-old children and their parents: lessons for policy and programs.

Early Head Start, a federal program begun in 1995 for low-income pregnant women and families with infants and toddlers, was evaluated through a randomized trial of 3,001 families in 17 programs. Interviews with primary caregivers, child assessments, and observations of parent-child interactions were completed when children were 3 years old. Caregivers were diverse in race-ethnicity, language, and other characteristics.

Child care quality matters: how conclusions may vary with context.

Three studies examined associations between early child care and child outcomes among families different from those in the National Institute of Child Health and Human Development (NICHD) Early Child Care Research Network study. Results suggest that quality is an important influence on children's development and may be an important moderator of the amount of time in care. Thus, the generalizability of the NICHD findings may hinge on the context in which those results were obtained.

Arranging child care.

More than half of the children in families supported by welfare are under age six, and another third are in grade school. The mothers of these children cannot leave welfare for employment unless they can find and pay for child care. Yet, as this article points out, the child care needs of these families are not easily met: Many require care for infants and toddlers, care at odd hours, and care in poor neighborhoods-all of which are scarce.

Do school-based health centers improve adolescents' access to health care, health status, and risk-taking behavior?

Purpose: The purpose of this investigation was to assess the School-Based Adolescent Health Care Program, which provided comprehensive health-related services in 24 school-based health centers.

Methods: The outcomes evaluation compared a cohort of students attending 19 participating schools and a national sample of urban youths, using logit models to control for observed differences between the two groups of youths. Outcome measures included self-reports concerning health center utilization, use of other health care providers, knowledge of key health facts, substance use, sexual activity, contraceptive use, pregnancies and births, and health status.

Child care for children in poverty: opportunity or inequity?

Data from a nationally representative survey of child care centers and a 5-site, observational study of centers were used to examine the quality of care provided to children from low-income families. Comparisons were made to a national sample of centers; among Head Start, public school-sponsored, and other community-based subsidized centers; and among centers that served families from differing socioeconomic groups. The quality of care in centers that served predominantly low-income children was adequate, but highly variable, with structural indices exhibiting higher quality than observations of global quality and of staff-child interactions.
