“…In particular, energy from snack foods is significantly underreported among obese women (Kerver et al, 2006). In the study reported here, application of conversation analysis principles (Tapsell et al, 2000) should have improved the accuracy of reporting for both meals and snacks, although this was not directly tested. Normal day-to-day variability in intake is likely to contribute more to overall error than underreporting, as no difference in underreporting of energy intake between weekdays and weekend days has been reported in overweight women (Heitmann and Lissner, 1995), although similar findings have not been reported for men.…”

Minimizing random error in dietary intakes assessed by 24-h recall, in overweight and obese adults

Objective: To determine the minimum number of days of dietary intake interviews required to reduce the effects of random error (day-to-day variability in dietary intake) when using the multiple-pass, multiple-day, 24-h recall method. Design: Cross-sectional study. Setting: University research department. Subjects: A total of 50 healthy non-smoking overweight and obese (body mass index ¼ 26-40 kg/m 2 ) adult men and women aged 39-45 years completed the study. Participants were randomly selected from volunteers for a larger unrelated study. Interventions: Each participant completed 10, multiple-pass, 24-h recall interviews on randomly chosen days over 4 weeks. The minimum number of record days was determined for each macronutrient (carbohydrate, fat, protein) and energy, for each gender, to obtain a 'true' (unobservable) representative intake from reported (observed) dietary intakes. Results: The greatest number of days required to obtain a 'true' representative intake was 8 days. Carbohydrate intakes required the greatest number of days of dietary record among males (7 days), whereas protein required the greatest number of days among females (8 days) in this cohort. Sunday was the day of the week that showed greatest variability in macronutrient intakes. Protein (Po0.05) and fat (Po0.001) intakes were significantly more variable than carbohydrate on Sundays compared with weekdays, for both men and women. Conclusion: A logistically achievable 8 days of dietary intake interviews was sufficient to minimize the effect of random error when using the multiple-pass, 24-h recall dietary intake method. Sunday should be included among the dietary interview days to ensure a 'true' representation of macronutrient intakes. This method can be confidently applied to small cohort studies in which dietary intakes from different groups are to be compared or to investigations of associations between nutrient intakes and disease.

“…For example, the telling of appropriate stories, set in within the cultural milieu, has been integrated into nutrition education and used within Aboriginal communities 40 . The overall approach also resonates with emerging work on the use of narrative in nutrition counselling, where history-taking and decisionmaking develop from the client telling their story 41 . All these approaches are based, in one way or another, on an acceptance that there resides within individuals, organisations and communities logic and practical reason which is worthy of regard and as a useful starting point for participative inquiry 42 .…”

Background: The role played by lay knowledge in understanding health inequalities has received increased interest recently. Very little is known, however, about how lay knowledge of food and health varies across social class. The present exploratory study compared and contrasted ways in which people from different social backgrounds draw on and use different forms of lay knowledge about food and health. Method: Parents from 40 families were recruited from two socio-economically different suburbs (20 families from each suburb). In-depth interviews were conducted with the mother and father in each family to examine lay knowledge about food and health. All interviews were transcribed and coded for specific themes. Responses from each suburb were compared and contrasted. Results: Different forms of lay knowledge about food and health were noted, especially concerning children's eating habits. Parents in the high-income suburb were more likely to discuss food and health in technical terms informed by contemporary nutritional or medical priorities. Parents in the low-income suburb did not share this discourse, but instead were more likely to discuss food in terms related to children's outward appearance or functional capacity. Conclusions and implications:The research highlights differences in lay knowledge about food and health across social class. It emphasises the need for public health nutrition policy-makers and practitioners to pay attention to lay knowledge on its own terms, rather than attempting to educate from predetermined assumptions, principles and standards.

“…As there is a strong relationship between plasma cholesterol and a-tocopherol (McGavin et al, 2001), plasma a-tocopherol results are expressed standardised to cholesterol (mmol a-tocopherol/mmol total cholesterol). Dietary intake was assessed by a dietitian by narrative diet history (Tapsell et al, 2000) and analysed using ESHA Food Processor (Version 8.0, ESHA Research, OR, USA). Depression scores were derived from administration of the Beck Depression Inventory (BDI).…”

Low plasma vitamin E levels in major depression: diet or disease?

et al. 2004

Objective: Levels of vitamin E have been reported to be lower in patients suffering major depression, but whether this is due to inadequate dietary intake or the pathophysiology of depression is not known, and was the subject of the present study. Setting: Wollongong, Australia. Methods: Plasma vitamin E (a-tocopherol) was measured in 49 adults with major depression, age (mean7s.d.): 47712 y. In a subset (n ¼ 19) usual dietary intake of vitamin E was determined by diet history. Results: Subjects had significantly lower plasma a-tocopherol (4.7170.13 mmol/mmol cholesterol) than has previously been reported for healthy Australians, and plasma a-tocopherol was inversely related to depression score (by Beck Depression Inventory) (r ¼ À0.367, Po0.009). Diet analysis indicated that 89% of subjects met or exceeded the recommended intake for vitamin E, and dietary intake was not related to plasma a-tocopherol level in this subset. Conclusion: These findings suggest that plasma levels of a-tocopherol are lower in depression, but this is not likely to be the result of inability to meet recommended dietary intake. Sponsorship: This study was supported in part by the Clover Corporation and the Australian Research Council.
