NCT03246490 | Completed DMC

• 1 other identifier: AA025193
• Study Type: interventional
• Target: 141

Brief Summary

This study aims to develop a phone app to assess gait differences at different levels of alcohol intoxication.

Conditions

Alcohol Drinking

Outcome Measures

Primary Outcomes (1)

• Phone App

  a phone app to compare gait changes with blood alcohol levels will be developed based on participant's gait during alcohol use

  data from each participant will be collected during a one-visit study session

Study Arms (1)

All Participants

OTHER

All participants complete the same study procedures, which involve drinking alcohol to a .08 blood alcohol level and walking short distances while their blood alcohol level is increasing to .08 and decreasing down to .00.

Other: All Participants

Interventions

All Participants OTHER

all participants will participate in the same protocol involving drinking alcohol to a .08 g% blood alcohol level

All Participants

Eligibility Criteria

• Age: 21 Years - 75 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• ages 21-65
• drinking at least 5 drinks per occasion for men (4 for women) during a single drinking episode at least once in the last month to ensure, for safety reasons, that people are accustomed to consuming alcohol in amounts comparable to what we will administer
• willingness to drink beer (since only beer will be provided in the session to standardize drinks more easily).

You may not qualify if:

• past 6 months or current treatment for alcohol or drug abuse by self-report (for ethical reasons)
• Score \> 5 on (the short version of the Michigan Alcohol Screening Test \[SMAST\]48) given during the screening interview
• positive family history of alcohol use disorder
• weight ≥ 230 lbs (to prevent excessive volume of beverage)
• current use of medications that are contraindicated for alcohol
• a health condition that contraindicates alcohol (e.g. peptic ulcer disease)
• a health condition that affects ability to walk
• if female, pregnant or nursing
• use of recreational drugs (e.g., marijuana, opioids, stimulants, benzodiazepines) within the last week (self-report plus urine screening cup)
• persons who report alcohol-induced flushing, an untoward reaction that is often accompanied by headache, nausea and other symptoms
