Introduction: Nutritional problems are one of the most important health issues among school-aged children, and modification of the nutritional status in children is as well important. Objective: Present study aims to determine the effectiveness of child to child teaching approach as compared to educator to child teaching approach on promotion of nutritional status of elementary school students...

Food frequency questionnaires are commonly used to assess habitual food intake. Although food frequency questionnaires are known to produce measurement error, the amount of error and effectiveness of correction methods are poorly understood. Twelve men from the Baltimore, MD/Washington, DC, area consumed an ad libitum diet for 16 weeks during the spring of 2001. At the end of the study period, ...

The aim of the present study was to describe the association of fast food consumption with BMI, energy intake and diet quality in a Mediterranean population. The subjects were Spanish men (n 1491) and women (n 1563) aged 25-74 years who were examined in 1999-2000, in a population-based cross-sectional survey in northeast Spain (Girona). Dietary intake was assessed using a FFQ that included four...

The effects of density and food on remating were investigated using Drosophila melanogaster. The frequency of remating was unaffected by density for some combinations of fly strains but was reduced at low relative densities for other combinations. Until females had used most of their stored sperm, remating was less likely when food was absent or contact with food was prevented. Food availabilit...

Tumor-induced reduction in food intake in 2 rat-tumor organisms was distributed approximately equally between reduction in average size (premature satiety) and reduction in frequency (impaired perception of hunger) of effective meals. In both organisms, the frequency of futile meals (activity at food dish without any food ingestion) increased in the tumor-bearing state, and total meal frequency...

BACKGROUND Fast-food consumption has increased greatly in the USA during the past three decades. However, the effect of fast food on risk of obesity and type 2 diabetes has received little attention. We aimed to investigate the association between reported fast-food habits and changes in bodyweight and insulin resistance over a 15-year period in the USA. METHODS Participants for the CARDIA st...

Alaska Native populations are experiencing a nutrition transition and a resulting decrease in diet quality. The present study aimed to develop a quantitative food frequency questionnaire to assess the diet of the Yup'ik people of Western Alaska. A cross-sectional survey was conducted using 24-hour recalls and the information collected served as a basis for developing a quantitative food frequen...

This population-based study examined whether residential or school neighborhood access to fast food restaurants is related to adolescents' eating frequency of fast food. A classroom-based survey of racially/ethnically diverse adolescents (n=2724) in 20 secondary schools in Minneapolis/St. Paul, Minnesota was used to assess eating frequency at five types of fast food restaurants. Black, Hispanic...

INTRODUCTION Biomarkers are a good choice to be used in the validation of food frequency questionnaire due to the independence of their random errors. OBJECTIVE To assess the validity of the potassium and sodium intake estimated using the Food Frequency Questionnaire ELSA-Brasil. SUBJECTS/METHODS A subsample of participants in the ELSA-Brasil cohort was included in this study in 2009. Sodiu...
