Healthy Behaviors Learning Task

Summary

This research is being done to study the impacts of a computerized learning task on health behaviors.

Description

Over 1/3 of U.S. adults over the age of 20 are obese and obesity is associated with a host of deleterious medical comorbidities, including heart disease, type 2 diabetes, and cancer, costing the U.S. approximately $147 billion annually. Novel approaches to address this public health crisis are needed. Although obesity is multiply determined, it is ultimately a disorder of positive energy balance, such that weight loss requires increases in physical activity and improvements in choosing healthy over unhealthy foods. People who are strongly motivated to eat are more obese, and derive less benefit from weight loss treatments. There are two general approaches to addressing this pattern: 1) increase the reinforcing value of healthy foods and/or 2) increase an individual's self-control, i.e., the ability to inhibit approach responses to less healthy foods.

Emerging research has begun to develop and test training programs that directly modify tendencies to approach one type of stimulus while resisting temptation of another type of stimulus for problems other than obesity. For example, researchers have been able to train heavy drinkers to decrease their weekly alcohol intake7 and chocolate-lovers to reduce their chocolate intake. However, these researchers did not also incorporate increasing interest in alternatives (e.g., drinking water instead of beer). This training mechanism has also yet to be applied to research on obesity and decreasing intake of unhealthy foods.

Participants will be first trained via a computerized training task to inhibit responses to high-calorie (unhealthy) foods, and to approach alternative low-calorie, high-nutrient (healthy) foods, in order to test the tasks efficacy.

Medical and Biotech [MESH] Definitions

The observation and analysis of movements in a task with an emphasis on the amount of time required to perform the task.

Ongoing scrutiny of a population (general population, study population, target population, etc.), generally using methods distinguished by their practicability, uniformity, and frequently their rapidity, rather than by complete accuracy.

The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from PREVALENCE, which refers to all cases, new or old, in the population at a given time.

Monitoring of rate of occurrence of specific conditions to assess the stability or change in health levels of a population. It is also the study of disease rates in a specific cohort, geographic area, population subgroup, etc. to estimate trends in larger population. (From Last, Dictionary of Epidemiology, 2d ed)

The change in gene frequency in a population due to migration of gametes or individuals (ANIMAL MIGRATION) across population barriers. In contrast, in GENETIC DRIFT the cause of gene frequency changes are not a result of population or gamete movement.
