Abstract
BACKGROUND The Rome criteria for irritable bowel syndrome (IBS) have been revised and are expected to apply only to the subset of Rome III IBS subjects with abdominal pain as predominant symptom, occurring at least once a week. The aim of this study was to determine the percentage of Rome III IBS subjects that fulfills Rome IV criteria and to evaluate differences between Rome IV-positive and Rome IV-negative subjects. METHODS Four hundred and four Rome III IBS subjects completed a 14-day end-of-day symptom diary, the Gastrointestinal Symptom Rating Scale (GSRS), Hospital Anxiety and Depression Scale, and RAND 36-item Short-Form Health Survey (SF-36). Diary-based surrogate Rome IV criteria were defined as occurrence of abdominal pain at least 1 day each week with a severity of ≥2 (mild; definition 1) or ≥3 (considerable; definition 2). KEY RESULTS Using surrogate Rome IV criteria, 353 (87.4%, definition 1) and 249 (61.6%, definition 2) subjects were defined as Rome IV positive. These patients were more often female, younger, and recruited from secondary/tertiary care compared with Rome IV-negative subjects. They also presented with higher abdominal pain scores and gastrointestinal (GI) symptom severity on both end-of-day diary and GSRS, higher psychological symptom scores, and lower quality of life compared with Rome IV-negative subjects. CONCLUSIONS AND INFERENCES The Rome IV IBS population likely reflects a subgroup of Rome III IBS patients with more severe GI symptomatology, psychological comorbidities, and lower quality of life. This implies that results from Rome III IBS studies may not be directly comparable to those from Rome IV IBS populations.

Abstract
Easily utilized questionnaires estimating dietary calcium intake would be a valuable asset to promoting skeletal health as well as a helpful research tool. Two calcium questionnaires, one online and one printed, were each compared with dietary calcium intake measured by a 3-day diet record. Women completed the questionnaires in a randomized order and kept a 3-day food record at home, returning it by mail. The ethnicity of the 140 female study participants was 102 white, 12 African American, 16 Asian, and 10 Latina. The mean age (+/-standard deviation) was 49+/-15 years, with a range of 22.7 to 89.9 years. Measures used included an online calcium quiz, a printed calcium food frequency questionnaire, and one 3-day diet record. Data analysis was done using Pearson correlation coefficients. Sub-analyses were conducted by ethnicity. The correlation between each questionnaire and the daily calcium intake from the diet records was 0.37, P<0.001. Among the ethnic subgroups, the correlations were highest for African-American women, followed by white women. There was also a trend toward higher correlations in younger women. These simple calcium assessment tools, taking fewer than 5 minutes to complete, have correlation values with diet records similar to more complex food frequency questionnaires reported in the literature. These questionnaires may provide valuable tools to estimate calcium intake in research, clinical, and community settings.

Abstract
It is important to identify the role of nutrition in the treatment and prevention of osteoporosis. The goal of this study was to compare the equivalency of nutrient intakes assessed by diet records and the Arizona Food Frequency Questionnaire and the associations of these nutrients with bone mineral density (BMD). This is a secondary analysis of cross-sectional data that was analyzed from six cohorts (fall 1995 to fall 1997) of postmenopausal women (n=244; 55.7+/-4.6 years) participating in a 12-month, block-randomized, clinical trial. One-year dietary intakes were assessed using 8 days of diet records and the Arizona Food Frequency Questionnaire. Participants' BMD was measured at the lumbar spine (L2-L4), femur trochanter, femur neck, Ward's triangle, and total body using dual-energy x-ray absorptiometry. Linear regression analyses (P< or =0.05) were adjusted for the effects of exercise, hormone therapy use, body weight at 1 year, years post menopause, and total energy intake. Significant correlations (r=0.30 to 0.70, P< or =0.05) between dietary assessment methods were found with all dietary intake variables. Iron and magnesium were consistently and significantly positively associated with BMD at all bone sites regardless of the dietary assessment method. Zinc, dietary calcium, phosphorous, potassium, total calcium, and fiber intakes were positively associated with BMD at three or more of the same bone sites regardless of the dietary assessment method. Protein, alcohol, caffeine, sodium, and vitamin E did not have any similar BMD associations. Diet records and the Arizona Food Frequency Questionnaire are acceptable dietary tools used to determine the associations of particular nutrients and BMD sites in healthy postmenopausal women.

Abstract
This study tested the validity of four measures of dietary restraint: Dutch Eating Behavior Questionnaire, Eating Inventory (EI), Revised Restraint Scale (RS), and the Current Dieting Questionnaire. Dietary restraint has been implicated as a determinant of overeating and binge eating. Conflicting findings have been attributed to different methods for measuring dietary restraint. The validity of four self-report measures of dietary restraint and dieting behavior was tested using: (1) factor analysis, (2) changes in dietary restraint in a randomized controlled trial of different methods to achieve calorie restriction, and (3) correlation of changes in dietary restraint with an objective measure of energy balance, calculated from the changes in fat mass and fat-free mass over a six-month dietary intervention. Scores from all four questionnaires, measured at baseline, formed a dietary restraint factor, but the RS also loaded on a binge eating factor. Based on change scores, the EI Restraint Scale was the only measure that correlated significantly with energy balance expressed as a percentage of energy required for weight maintenance. These findings suggest that, of the four questionnaires tested, the EI Restraint Scale was the most valid measure of the intent to diet and actual caloric restriction.

The evaluation of an electronic visual analogue scale system for appetite and mood.
Whybrow, S, Stephen, JR, Stubbs, RJ
European journal of clinical nutrition. 2006;(4):558-60
Abstract
Our objective was to evaluate a new electronic visual analogue scale (VAS) system for logging subjective motivation to eat ratings. In total, 10 men and 10 women completed both electronic and traditional pen and paper versions of the questionnaire every hour of the waking day. Subjects consumed a standard medium-fat diet, which was fixed at 1.6.BMR. Correlation coefficients for scores obtained by both methods were significant for all questions, with R(2) values ranging from 67 to 87%. However, Bland and Altman plots and paired t-tests identified significant bias between the two methods for five of the nine individual questions. These were questions that tended to be scored more towards the ends of the VAS. The new electronic VAS produces comparable, but not interchangeable, results to the traditional pen and paper method in the study of appetite and mood, while offering advantages of improved reliability in data collection.

Abstract
Researchers at the National Cancer Institute developed a new cognitively based food frequency questionnaire (FFQ), the Diet History Questionnaire (DHQ). The Eating at America's Table Study sought to validate and compare the DHQ with the Block and Willett FFQs. Of 1,640 men and women recruited to participate from a nationally representative sample in 1997, 1,301 completed four telephone 24-hour recalls, one in each season. Participants were randomized to receive either a DHQ and Block FFQ or a DHQ and Willett FFQ. With a standard measurement error model, correlations for energy between estimated truth and the DHQ, Block FFQ, and Willett FFQ, respectively, were 0.48, 0.45, and 0.18 for women and 0.49, 0.45, and 0.21 for men. For 26 nutrients, correlations and attenuation coefficients were somewhat higher for the DHQ versus the Block FFQ, and both were better than the Willett FFQ in models unadjusted for energy. Energy adjustment increased correlations and attenuation coefficients for the Willett FFQ dramatically and for the DHQ and Block FFQ instruments modestly. The DHQ performed best overall. These data show that the DHQ and the Block FFQ are better at estimating absolute intakes than is the Willett FFQ but that, after energy adjustment, all three are more comparable for purposes of assessing diet-disease risk.

The journal of nutrition, health & aging. 2001;(1):22-8
Abstract
BACKGROUND In investigating anorexia of ageing, attention is often given to physical and psychological determinants of appetite in the elderly but little has been done to provide information on self-assessment of appetite and sensory perceptions in the elderly. OBJECTIVES to provide data and detect possible differences in self-assessment of appetite, hunger feelings and sensory perception in different health group of elderly using the Appetite, Hunger feelings and Sensory Perception (AHSP) questionnaire. METHODS three health categories of elderly subjects were used for the present study: free-living with no help, free-living with help and nursing home elderly. For each group, collected data were general characteristics, anthropometry and answers to the AHSP. The AHSP questionnaire includes 29-items focusing on feelings of hunger and appetite as well as taste and smell perception addressing both the present situation and the period before retirement. RESULTS Significant differences were observed between the 3 health groups for appetite, hunger feelings, present taste perception and present smell perception (P<0.05). Appetite and hunger were found to be related to body weight in the healthiest but not in the others. CONCLUSION A decline in health status is paired with a decrease in appetite, hunger feelings and sensory perceptions of elderly subjects.
