Exploratory analysis of children's nutrition programs in Canada.

This survey examined the processes by which programs feeding hungry children in Canada are initiated, implemented and sustained. The responses of 32 operators of these programs were obtained by semi-structured telephone interviews and were analysed using qualitative research methods. Concerned citizens within the community and teachers were the major proponents for programs; their primary indicators of need were children's hunger-related behaviours. Programs generally provided the breakfast or lunch meal, were overseen by a board, and were operated by a mix of paid and volunteer staff. A lack of resources, problems with parents and the community, and managerial stresses were the main perceived barriers to program continuance. Programs run by communities generally had more need for resources, expressed lower confidence in their sustainability, and were less likely to cooperate with other groups than school-run programs. While some programs deliberately tried to avoid stigmatization, program operators did hold some prejudicial views about the communities they served and few programs could be considered empowering to users.

Periconceptional nutrition programs development of the cardiovascular system in the fetal sheep.

It has been proposed that fetal adaptations to intrauterine nutrient deprivation permanently reprogram the cardiovascular system. We investigated the impact of restricted periconceptional nutrition and/or restricted gestational nutrition on fetal arterial blood pressure (BP), heart rate, rate pressure product, and the fetal BP responses to ANG II and the angiotensin-converting enzyme inhibitor captopril during late gestation. Restricted periconceptional nutrition resulted in an increase in fetal mean arterial BP between 115 and 125 days gestation (restricted 41.5 +/- 2.8 mmHg, n = 12; control 38.5 +/- 1.5 mmHg, n = 13) and between 135 and 147 days gestation (restricted 50.5 +/- 2.2 mmHg, n = 8; control 42.5 +/- 1.9 mmHg, n = 10) as well as an increase in the rate pressure product in twin, but not singleton, fetuses between 115 and 147 days gestation. Mean BP and fetal plasma ACTH were also positively correlated in twin, but not singleton, fetuses. This is the first demonstration that maternal undernutrition during the periconceptional period results in an increase in fetal arterial BP. This increase occurs concomitantly with an increase in fetal ACTH but is not dependent on activation of the fetal renin-angiotensin system.

Sampling and data collection methods in the National Evaluation of School Nutrition Programs.

A nested sampling design is described in which school districts are selected, schools within those districts that cover grades one through 12 are selected, and finally students within each of the grades are selected. The article describes how nutritional status information is collected from each student, economic and food expenditure data are collected from the students' parents, and information on food services is collected from district and school administrators. Sample weighting and adjustments for nonresponse bias are discussed in the appendix.
