RESUMEN
PURPOSE: To compare (1) fluid, food and nutrient intake obtained with a paper versus an online version of a 7-day food record and (2) user's acceptability of both versions of the food record. METHODS: A cross-over study was carried out in 2010 in France. A total of 246 participants aged 18-60 years reported their food and fluid intake using both versions of the 7-day food record, separated by a 7- to 14-day washout period. To help participants in estimating consumed portions, both versions of the food record were supported by a photographic booklet of standard portions and containers. At the end of the study protocol, participants completed a questionnaire designed to assess the acceptability of the two questionnaires. RESULTS: The reported water intake of fluids was significantly higher with the online version compared with the paper version (respectively 1348 ± 36 and 1219 ± 34 mL/day, p < 0.0001). No difference was found between methods in terms of energy intake and the consumption of most food categories, macro- and micronutrients. Furthermore, 77 % of the participants preferred the online method to the paper version. CONCLUSIONS: Fluid intake, but not food intake, reported with the online 7-day food record was higher in comparison with the paper version. In addition, the online version was preferred by users. In population surveys, the online record is therefore a relevant alternative, and even a preferred alternative in the case of fluid intake, to the paper record.

BACKGROUND/OBJECTIVES: To assess the intake of fluid in healthy French children, adolescents, adults and seniors, considering amounts, types of beverages, time and place of consumption. SUBJECTS/METHODS: Data regarding fluid intake were extracted and analyzed from the National Intake Survey, which was conducted in quota samples of the French population (Comportement et Consommations Alimentaires en France study). Seven-day questionnaires were administered to free-living individuals in 2002-2003. A total of 566 children (aged 6-11 years), 333 adolescents (aged 12-19 years), 831 adults (aged 20-54 years) and 443 seniors (aged >or=55 years) were included in this study. RESULTS: The average total intake of fluid was 1-1.3 l per day depending on age groups. Water accounted for about one-half of daily fluid intake. The contribution of other types of beverages varied with age (for example, dairy drinks in children and adolescents; alcoholic drinks in adults and seniors). Intake of sodas (including regular and light) was highest in adolescents (169 ml a day). Beverages were mainly consumed at home during meals. CONCLUSIONS: This is the first description of fluid intake in French children, adolescents, adults and seniors, considering amounts, types of beverages, time and place of intake. It shows that water is the main source of fluid in all age groups. Selection of various types of beverages is different according to age.

BACKGROUND: The aim of the study was to compare preoperative transrectal ultrasound findings with final histopathological stage after radical prostatectomy to determine the value of TRUS in preoperative staging of prostate cancer. METHODS: The evaluation was performed as a retrospective study. In 114 radical prostatectomy specimens the histopathological, ultrasound and rectal digital findings were correlated. Mean age of patients was 63 years and in all patients a radical retropubic prostatectomy was performed. RESULTS: Organ confined PC was found correctly with TRUS in 68% and capsular penetration in 32%. Corresponding findings with digital rectal examination (DRE) were 68% and 17% respectively. Sensitivity of TRUS in organ confined PC (T1-2) was 66.1% (DRE 68.5%), specificity 32.6% (DRE 20%) and positive predictive value 55.7% (DRE 49.3%). Sensitivity, specificity and positive predictive value of TRUS for stage T3 (a,b,c) were 32.6%, 68.4% and 45.5% respectively. A separate evaluation of stage T3c revealed for TRUS: sensitivity 41.2%, specificity 81.8% and positive predictive value 36.8%. CONCLUSION: On the basis of this retrospective analysis, and due to the low sensitivity and specificity, TRUS is not suitable for adequate preoperative staging of prostatic cancer.

OBJECTIVE: This study was conducted to assess nutrient intake outside the home of 629 people representative of the French population. SUBJECTS: The study population consisted of 629 people aged 15 years and over. They were recruited in a randomized way with two levels (town and household). METHOD: Food intake outside the home was assessed by self-completed estimated record for 7 d. Individuals referred to photographs to estimate portions. Nutrient intake has been calculated for energy, protein, carbohydrate, fat and some minerals (calcium, phosphorus, magnesium, iron). RESULTS: Lunches and dinners eaten out are on average too rich in protein (20% of the energy), too high in fat (40-43% of the energy) and do not contain enough carbohydrate. The percentage of energy from sugars varies between 11% for lunch and 30% for breakfast. Mean intake of nutrients by beverages drunk outside the home decrease with the age of consumers. CONCLUSION: This study shows that foods and drinks consumed outside the home in France are on average too rich in fat and protein.

In this paper, we try to understand the motivations and characteristics of people susceptible to be volunteers for the SU.VI.MAX study. The objective of this study will be to recruit and to follow during 8 years, a cohort of 15,000 subjects at a national level, for an intervention trial in the field of nutritional prevention. A short media campaign has been organised to recruit "1,000 volunteers to help to test and to validate tools specifically developed for the SU.VI.MAX study". In total, 15,789 subjects matching selection criteria answered to our invitation. All received a short questionnaire; 10,984 sent back correctly filled up questionnaires (70%) and 1005 were selected at random for a complete analysis. A lexical analysis of motivations disclosed 6 different groups organised in two poles. The pole of true altruists with a speech relative to notions such as "volunteers-benevolent" (7% of subjects), wishes to participate to a "humane task" (9% of subjects) or to progress of medical research (27% of subjects). The other pole corresponds to people interested personally by the theme of the project with 3 kinds of speech: personal past history (13% of subjects), interest for foods fortified with vitamins and/or minerals (19% of subjects) or for relationships between food consumption and health (22% of subjects).
