“…Older persons may also under-report energy intake. [67][68][69] In our previous analyses, we showed that including only plausible reports resulted in stronger relationships of both eating patterns and dietary composition with BMI in subjects across all age groups. 22,38,39 Our studies also provided strong evidence that when implausible reporting occurs, whole eating occasions are omitted, and reported portion sizes and energy density of both meals and snacks are lower in the total sample compared to the sample limited to plausible reporters.…”

Objective: To compare relative associations of eating patterns and dietary composition with body mass index (BMI) in younger (aged 20-59 years, n ¼ 1792) and older (aged 60-90 years, n ¼ 893) participants in the Continuing Survey of Food Intakes by Individuals, collected 1994Individuals, collected -1996. Methods: Data from two 24-h dietary recalls from individuals reporting physiologically plausible energy intake (within 722% of predicted energy requirements, based on previously published methods) were used. Results: Mean reported energy intake was 96 and 95% of predicted energy requirements in younger and older subjects, respectively. Older subjects were less likely than younger subjects to skip a meal, but snacking was common in both age groups. Fiber density was significantly higher in the older group. A higher BMI in both age groups was associated with a higher total daily energy intake, and higher energy intakes at all eating occasions. In both age groups, eating frequency was positively associated with energy intake, and eating more than three times a day was associated with being overweight or obese. In the younger group but not the older group, a lower fiber density coupled with higher percentage of energy from fat was independently associated with having a higher BMI. Conclusions: While no one eating occasion contributes more than any other to excess adiposity, eating more often than three times a day may play a role in overweight and obesity in both younger and older persons. A reduced satiety response to dietary fiber in addition to lower energy expenditure may potentially further contribute to weight gain in older persons.

“…The %EI from fat was inversely related to the percentage of EI underestimation among 30 obese men, indicating selective underestimation of fat (8). Selective underesti mation of fat and selective overestimation of protein were also observed in 64 older people (10). These find ings may have a substantial impact on studies of diet and health because misleading conclusions with regard to diet and health may be drawn due to selective mises timation of dietary intake (54).…”

“…Not only have several factors which are associated with EI underestimation been indicated (3)(4)(5)(6), but it appears that a person whose EI is underestimated on one occa sion is likely to have an underestimated EI on other occasions (7). Furthermore, underestimation may not be food and nutrient neutral and may distort the actual balance of foods and nutrients (3,(8)(9)(10).…”

“…The basis of the study was a measurement of TEE by ACC (study days 6-32) with a collection of data on dietary intake using 7dWR (days 5-11) and DHQ (day 8) and on behavioral and psycho logical characteristics using questionnaires (days [8][9][10][11][12] and anthropometric measurements (days 5, 12, and 33). The subjects were strongly encouraged not to change their dietary habits or lifestyle during the study.…”

Objective: To nutritionally analyse mean energy intake (EI) from different 3 d intervals within a 7 d recording period and to evaluate the seasonal effect on energy and nutrient intake. Design: Cross-sectional study of dietary intake collected with 7 d food diaries. Setting: Aberdeen, north-east Scotland, UK, between 2002 and 2004. Subjects: Participants from two long-term trials were pooled. These trials, investigating genetic and environmental influences on body weight, were the Genotyping And Phenotyping (GAP) study and a cohort observational study, Rowett Assessment of Childhood Appetite and metaboLism (RASCAL). There were 260 Caucasian adults, BMI range 16?7-49?3 kg/m 2 , age range 21-64 years. Results: Mean EI for Wednesday, Friday and Saturday had the closest approximation to the 7 d mean (0?1 % overestimate). A gender 3 season interaction (P 5 0?019) with a different intake pattern for females and males was observed. For females, lower mean (SE) EI was recorded in summer (8117 (610) kJ) and autumn (7941 (699) kJ) compared with spring (8929 (979) kJ) and winter (8132 (1041) kJ). For males, higher mean (SE) EI was recorded in summer (10 420 (736) kJ) and autumn (10 490 (1041) kJ) compared with spring (9319 (1441) kJ) and winter (9103 (1505) kJ). Conclusions:The study results indicate that 3 d weighed intakes recorded from Wednesday, Friday and Saturday are most representative of 7 d habitual intake in free-living subjects. They also indicate that seasonality has a limited effect on EI and no effect on macronutrient intake. Keywords Dietary assessment Seasonal food intakeWeighed intake Food diary Metabolic rateWeighed diet records are considered the 'gold standard' when examining free-living energy and nutrient intake, with seven days of recording regarded as the best compromise between accuracy, investigator workload and subject compliance (1) . In practice however, 3 d weighed dietary records are often the assessment tool chosen by investigators for intervention studies, as they are deemed to be less intrusive for subjects (2) and can therefore improve subject recruitment. With the shorter recording period comes the concern whether the three recording days are representative of habitual intake (3) . Therefore, much research has focused on identifying feasible intakes and attempting to correct intake data. Specifically, the effects of 'misreporting' or 'under-reporting' of food intake (4) has been a main focus of attention, following better energy expenditure (and thus energy balance) methodology (5) . Within the literature, there has been less emphasis on the practical issues such as when to ask subjects to record, i.e. which day(s) or the effect of season, which may have an effect on achieving an assessment of habitual intake. Hartman et al. (6) reported that non-consecutive days were preferable due to a correlation between eating behaviour on consecutive days and Bingham (7) recommended a 3 d diary to include one weekend day and two weekdays, since weekend days are known to indicate higher repor...
