Title
Contextual influences on dietary behavior in older adults: How screen time, physical location, and social environment are associated with dietary intake
Summary
The current literature on social, physical, and other contextual factors indicates that these elements may play a significant role in affecting energy intake and dietary quality. The majority of these studies, however, have been conducted in child and adolescent populations, therefore it is unclear whether and to what extent these same factors are associated with dietary patterns of older adults. This study will analyze IDATA participant responses to the ASA24 dietary assessment tool to help elucidate this research gap. We will use the first completed ASA24 record for each participant from each assessment date to investigate the associations of screen time, eating location, and presence of others with reported dietary intake for total energy, macronutrient consumption, vitamin and mineral intake, and food groups. We will also consider other potential correlates of dietary quality, including the number of meals per day and the time at which a particular meal is consumed. We envision this research will provide valuable insights into the eating behaviors of older adults, which may aid researchers in developing dietary interventions and effecting diet-related behavior change in older populations.
Aims

Our primary aims are to:
1) assess how TV and/or computer use at meals is associated with diet in older populations
2) determine the association of different eating locations with diet in older populations
3) understand the relationship between eating with family and/or others and diet in older populations
Secondary aims include:
1) assess the relationship between number of meals per day and diet in older populations
2) determine the association between time of meals and diet in older populations
