6-n-Propylthiouracil sensitivity and obesity status among ethnically diverse children.

Objective: To examine the relationship of 6-n-propylthiouracil (PROP) sensitivity to BMI while statistically controlling for demographic characteristics in two age groups of children: 9-10 years and 17-18 years (n 1551).

Design: Cross-sectional design with a multi-ethnic (White, African-American, Hispanic, Other) sample of 813 children aged 9-10 years and 738 children aged 17-18 years. Children were recruited from local elementary and high schools with at least 30 % minority ethnic enrolment.

Grains are similarly categorized by 8- to 13-year-old children.

This study assessed how 8- to 13-year-old children categorized and labeled grain foods and how these categories and labels were influenced by child characteristics. The main hypotheses were that children categorized foods in consistent ways and these food categories differed from the professional food categories. A set of 71 cards with pictures and names of grain foods from eight professionally defined food groups was sorted by each child into piles of similar foods.

Social support is a primary influence on home fruit, 100% juice, and vegetable availability.

Children tend to eat more fruit and vegetables when more are available in the home. We proposed and tested a model that predicts the availability at home (hereinafter termed "home availability") of fruit, 100% juice, and vegetables, using new measures of frequency of food shopping, purchase, and comparative purchase outcome expectancies (ie, the perceived benefits and costs of purchasing fruit and vegetables), home food pantry management practices, family social support for purchasing fruit and vegetables, food shopping practices, and body mass index (BMI). Participants (N=98) were recruited in 2004 in front of grocery stores and completed two telephone interviews.

Fruit and vegetables are similarly categorised by 8-13-year-old children.

Objective: This exploratory study assessed how 8-13-year-old children categorised and labelled fruit and vegetables (FaV), and how these were influenced by child characteristics, to specify second-level categories in a hierarchical food search system for a computerised 24 h dietary recall (hdr).

Design: Two sets of food cards, sixty-seven for fruit (F) and sixty-four for vegetables (V), with pictures and names of FaV from ten professionally defined food categories were sorted, separately, by each child into piles of similar foods. Demographic data, BMI and 6-n-propylthiouracil (PROP) taster status were obtained.

Diverse food items are similarly categorized by 8- to 13-year-old children.

Objective: Assess how 8- to 13-year-old children categorized and labeled food items for possible use as part of a food search strategy in a computerized 24-hour dietary recall.

Design: A set of 62 cards with pictures and names of food items from 18 professionally defined food groups was sorted by each child into piles of similar food items.

Setting: Participants attended the Children's Nutrition Research Center in the summer 2006.

Home fruit, juice, and vegetable pantry management and availability scales: a validation.

Home fruit, 100% juice, and vegetables (FJV) availability is related to increased FJV consumption by children. While FJV must be purchased for use in the home, no scales have been reported on home FJV pantry management practices. A scale for home FJV pantry management practices was generated from focus group discussions with diverse 162 food shoppers.

Mixed foods are similarly categorized by 8-13 year old children.

Food search in a computerized 24h dietary recall (24hdr) for children should be easiest when the categories reflect children's categorization of foods, in contrast to professional categories. This study assessed how 8-13 year old children categorized and labeled mixed foods (e.g.

Parent outcome expectancies for purchasing fruit and vegetables: a validation.

Objective: To validate four scales -- outcome expectancies for purchasing fruit and for purchasing vegetables, and comparative outcome expectancies for purchasing fresh fruit and for purchasing fresh vegetables versus other forms of fruit and vegetables (F&V).

Design: Survey instruments were administered twice, separated by 6 weeks.

Setting: Recruited in front of supermarkets and grocery stores; interviews conducted by telephone.

Fruit and vegetable shopping practices and social support scales: A validation.

Objective: To assess the psychometric characteristics of new scales of shopping practices and social support for purchasing fruits and vegetables.

Design: Participants were recruited in front of diverse grocery stores. Telephone data collection was done on 2 occasions, separated by 6 weeks.

Protecting the Navajo People through tribal regulation of research.

This essay explores the process and issues related to community collaborative research that involves Native Americans generally, and specifically examines the Navajo Nation's efforts to regulate research within its jurisdiction. Researchers need to account for both the experience of Native Americans and their own preconceptions about Native Americans when conducting research about Native Americans. The Navajo Nation institutionalized an approach to protecting members of the nation when it took over Institutional Review Board (IRB) responsibilities from the US Indian Health Service (IHS) in 1996.

Food-purchasing patterns for home: a grocery store-intercept survey.

Objectives: To identify the most common frequency of food-purchasing patterns and relate this pattern to characteristics of individuals and families.

Design: A customer-intercept survey was conducted in the greater Houston area, Texas, USA, in 2002. The frequency of food shopping at supermarkets, convenience stores and restaurants to buy food for eating at home was assessed.
