This paper examines the impacts of four abstinence-only education programs on adolescent sexual activity and risks of pregnancy and sexually transmitted diseases (STDs). Based on an experimental design, the impact analysis uses survey data collected in 2005 and early 2006 from more than 2,000 teens who had been randomly assigned to either a program group that was eligible to participate in one of the four programs or a control group that was not. The findings show no significant impact on teen sexual activity, no differences in rates of unprotected sex, and some impacts on knowledge of STDs and perceived effectiveness of condoms and birth control pills

In evaluations of marriage interventions, for example, a key outcome--relationship quality--is undefined when a couple splits up. This article shows how treatment-control differences in mean outcomes can be misleading when outcomes are not defined for everyone and discusses ways to identify the seriousness of the problem.

Design: Data from 24-hour recalls collected in the 2002 Feeding Infants and Toddlers Study were analyzed. Multivariate regressions were used to explore the relationship between portion size and usual energy intake as well as the relationship between portion size, number of eating occasions, number of unique foods, and energy density.
Objective: This article describes the steps in the planning and development of the 2002 Feeding Infants and Toddlers Study.
Methods: We describe the study's rationale, sampling methodology, survey questionnaire development, dietary methodology, field data collection, and data processing and analysis. A brief review of existing national nutrition surveys and studies of infants and toddlers, and available study designs and dietary methods, is also included.
Objectives: To examine the nutrient intakes, foods consumed, and feeding patterns of infants and toddlers participating in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).
Design: Cross-sectional telephone survey, including 24-hour dietary recalls of infants' and toddlers' food and nutrient intakes, as reported by parents or other primary caregivers.
Subjects: National random sample of 3,022 children ages 4 to 24 months who participated in the 2002 Feeding Infants and Toddlers study.
Objective: To describe meal and snack patterns of infants and toddlers.
Design: A cross-sectional telephone survey in which mothers reported their infants' and toddlers' food and beverage intakes for a 24-hour period.
Subjects: Subjects included 3,022 infants and toddlers, ages 4 to 24 months, in the Feeding Infants and Toddlers Study.
Objective: To assess adherence to infant feeding recommendations among a sample of infants and toddlers four to 24 months of age in the United States.
Design: Descriptive analysis of data collected in the 2002 Feeding Infants and Toddlers Study (FITS) based on telephone interviews and 24-hour dietary recalls collected with the Nutrition Data System for Research of the University of Minnesota.
Subjects: A national random sample of 3,022 infants and toddlers age four to 24 months, including 2,024 infants age four to 11 months.
Objective: To describe the food consumption patterns of US infants and toddlers, 4 to 24 months of age.
Design: Descriptive analysis of data collected in the 2002 Feeding Infants and Toddlers study based on telephone interviews and 24-hour dietary recalls.
Subjects: A national random sample of 3,022 infants and toddlers age 4 to 24 months.
Objectives: To assess the nutrient adequacy of the diets of US infants and toddlers 4 to 24 months of age.
Design: Descriptive analysis of the usual nutrient intakes of infants and toddlers using 24-hour recall data from the 2002 Feeding Infants and Toddlers Study.
Subjects: A national random sample of 3,022 infants and toddlers, with 2 days of recall available for 703 sample members.
Objective: Describe the design, data collection procedures, and sample characteristics of the Feeding Infants and Toddlers Study.
Design: We conducted up to three telephone interviews with a random sample of parents or caregivers of infants and toddlers four to 24 months of age from March to July 2002. The three interviews included (a) a recruitment and household interview; (b) a 24-hour dietary recall, with supplementary questions on growth, development, and feeding patterns; and (c) a second dietary recall for a random subset of the sample.
Objectives: Racial differences in health status and use of health services persist in the United States and are not completely explained by differences in socioeconomic status. This study examines differences in use of health services between White and African American children enrolled in Medicaid, controlling for other factors that affect service use. We make comparisons for use of primary preventive services, diagnosis and treatment of selected common childhood illnesses, and Medicaid expenditures.

Methods: We linked Medicaid enrollment, Medicaid paid claims, and WIC participation files to birth certificates for children born in North Carolina in 1992. We used multiple regression analysis to estimate the effects of WIC participation on the use of health care services and Medicaid costs.
