“…The training session was conducted to improve the recording of data (Bolland et al, 1988(Bolland et al, , 1990. The training and instructions for recording dietary intake included the use of threedimensional food models, serving utensils, plates, bowls and other dishes that are used within the population to assist them with estimating portion sizes (Weber et al, 1997). During the training sessions, each subject recorded a selfreported dietary recall which was reviewed by the trainer.…”

The association of energy intake bias with psychological scores of women

Objective: Assess the association between reporting bias of dietary energy intake and the behavioral and psychological pro®les in women. Design: At baseline a series of questionnaires were administered to 37 women, (the Marlowe-Crowne Social Desirability Scale, Weinberger Adjustment Inventory (WAI), the Eating Disorder Inventory (EDI), the Restraint Scale and Sorensen-Stunkard's silhouettes). Subjects received training on how to record dietary records. Subjects recorded three days of dietary records to measure energy intake (EI) during a study to determine total energy expenditure (TEE) using doubly labeled water. Reporting accuracy (RA EIaTEE 6 100) was determined for each subject. Statistical analysis of the data used a mixed effects model accounting for within subject variability to determine if the psychological scores were associated with reporting accuracy. Setting and subject: Women were recruited with local advertisements in Tucson, Arizona. The women had a mean ( AE 1 s.d.) age of 43.6 AE 9.3 yrs, body mass index (BMI) of 28.7 AE 8.5 kgam 2 and total body fat (%TBF) of 31.9 AE 7.3%. Results: Age and %TBF were signi®cantly and inversely associated with RA. Furthermore, Social Desirability was negatively associated with RA. Body dissatisfaction and associating a smaller body size than one's own as being more healthy were also associated with a lower RA. Conclusions: These results suggest that Social Desirability and self image of body shape are associated with RA. Modi®cations in subject training may reduce the effect of these factors on RA.

“…more favourable nutrient intake (positive impact), these effects were only measured in the short term and usually in the laboratory setting (88)(89)(90)(91)(92)(93)(94)(95)(96)(97) . A follow-up study conducted 3 months after initial training about SS showed that the immediate positive impact had not been maintained (96) .…”

Serving size guidance for consumers: is it effective?

et al. 2012

Larger portion sizes (PS) may be inciting over-eating and contributing to obesity rates. Currently, there is a paucity of data on the effectiveness of serving size (SS) guidance. The aims of the present review are to evaluate SS guidance; the understanding, usability and acceptability of such guidance, its impact on consumers and potential barriers to its uptake. A sample of worldwide SS guidance schemes (n 87) were identified using targeted and untargeted searches, overall these were found to communicate various inconsistent and often conflicting messages about PS selection. The available data suggest that consumers have difficulty in understanding terms such as ‘portion size’ and ‘serving size’, as these tend to be used interchangeably. In addition, discrepancies between recommended SS and those present on food labels add to the confusion. Consumers generally understand and visualise SS best when expressed in terms of household measures rather than actual weights. Only a limited number of studies have examined the direct impact of SS guidance on consumer behaviour with equivocal results. Although consumers recognise that guidance on selecting SS would be helpful, they are often unwilling to act on such guidance. The challenge of achieving consumer adherence to SS guidance is formidable due to several barriers including chronic exposure to larger PS, distorted consumption norms and perceptions, the habit of ‘cleaning one's plate’ and language barriers for ethnic minorities. In conclusion, the impact of SS guidance on consumers merits further investigation to ensure that future guidance resonates with consumers by being more understandable, usable and acceptable.

“…Validity of self-reported energy intake JL Weber et al a modification of the method of Weber et al (1997) which included training participants in groups of four to eight. For this method, the women measured two samples each of solid, liquid and amorphous foods, estimated the portion sizes of 12 plastic food models, and learned how to measure and estimate the dimensions of solid foods by length, width and height or diameter.…”

Validity of self-reported energy intake in lean and obese young women, using two nutrient databases, compared with total energy expenditure assessed by doubly labeled water

et al. 2001

Objective: To compare self-reported total energy intake (TEI) estimated using two databases with total energy expenditure (TEE) measured by doubly labeled water in physically active lean and sedentary obese young women, and to compare reporting accuracy between the two subject groups. Design: A cross-sectional study in which dietary intakes of women trained in diet-recording procedures were analyzed using the Minnesota Nutrition Data System (NDS; versions 2.4=6A=21, 2.6=6A=23 and 2.6=8.A=23) and Nutritionist III (N3; version 7.0) software. Reporting accuracy was determined by comparison of average TEI assessed by an 8 day estimated diet record with average TEE for the same period. Results: Reported TEI differed from TEE for both groups irrespective of nutrient database (P < 0.01). Measured TEE was 11.10 AE 2.54 and 11.96 AE 1.21 MJ for lean and obese subjects, respectively. Reported TEI, using either database, did not differ between groups. For lean women, TEI calculated by NDS was 7.66 AE 1.73 MJ and by N3 was 8.44 AE 1.59 MJ. Corresponding TEI for obese women were 7.46 AE 2.17 MJ from NDS and 7.34 AE 2.27 MJ from N3. Lean women under-reported by 23% (N3) and 30% (NDS), and obese women under-reported by 39% (N3) and 38% (NDS). Regardless of database, lean women reported higher carbohydrate intakes, and obese women reported higher total fat and individual fatty acid intakes. Higher energy intakes from mono-and polyunsaturated fatty acids were estimated by NDS than by N3 in both groups of women (P 0.05).
