Using Encoding and Retrieval Strategies to Improve 24-hour Dietary Recalls Among Older Adults

Development and validation of a food frequency questionnaire (FFQ-Porto Alegre) for adolescent, adult and elderly populations from Southern Brazil

“…Food consumption of participants up to 90 years of age has a potential for bias due to attention and memory decline with age, and might be the reason for the paucity of studies in the elderly. However, the interviews were conducted face-to-face, lasted longer than those answered by adults, and discrepancies in responses were clarified with an adult living at the same house, as a strategy for collecting dietary data from elderly people 27 . Even though the sample was relatively small, it was representative of the target population.…”

Aging-Related Oxidative Stress in Healthy Humans

“…Older subjects ( 60 years) had body mass index (BMI) of 23. (Barrocas et al 1995;Ervin 1998;Vellas et al 2000). The physical activity was similar between groups of older subjects and adult subjects; this was measured with a physical activity questionnaire (Bertoldi et al 2006).…”

A methodological report from the Malmö Diet and Cancer study: development and evaluation of altered routines in dietary data processing

“…For instance, diet history methods may not be robust to changes in the interviewer [2]. Also, the ability of individuals to estimate portion-sizes and common consumption frequencies in usual diet methods may depend on the specific assessment aid [22,43,44], the interview technique [45,46], or the organisation of the food list [47]. Studies also suggest that usual diet reports may be affected by diverse factors like season of data collection [48], ethnicity and education [13], degree of obesity [7,49], socio-economic status [12], and the perception of societal norms [50,51].…”
