Acute Effects of Moderate Alcohol Consumption on Postural Stability in Older Adults
This study involved healthy community-living older adults in an investigation of the association between moderate alcohol consumption (AC) and acute changes in postural stability and whether the association differed according to pre-AC balance skills. Thirty-nine moderate drinkers aged ≥ 65 years (6...

| description | This study involved healthy community-living older adults in an investigation of the association between moderate alcohol consumption (AC) and acute changes in postural stability and whether the association differed according to pre-AC balance skills. Thirty-nine moderate drinkers aged ≥ 65 years (62% women; mean age: 73.9 ± 6.1 years) consumed a moderate dose of alcohol (0.4 g/kg; administered as two drinks). Breath alcohol concentration and postural stability were measured at five time points (pre-AC and 40, 80, 120, and 160 minutes post-AC) using unipedal stance time (UPST) and center of pressure (CoP) displacement. Pre-AC UPST was used to categorize participants into good-balance (≥30 seconds) and poor-balance ( |

Pre-AC UPST was used to categorize participants into good-balance (≥30 seconds) and poor-balance (<30 seconds) groups. Peak breath alcohol concentration was 30 mg/dL at 40 minutes post-AC. For all participants, postural stability declined significantly at 80 minutes post-AC (UPST, p = .005; anterior–posterior CoP displacement, p = .029). While the poor-balance group did not show a significant decrease in UPST duration over the course of the study, the good-balance group experienced significant decline at 80 minutes compared with baseline (p < .001) and remained above the 30-second UPST cutoff. Both groups experienced similar worsening in anterior–posterior CoP displacement at 80 minutes post-AC. Thus, moderate AC was associated with acute decline in postural stability in older adults. The worsened anterior–posterior CoP displacement post-AC in the poor-balance group was of particular concern because these participants were already at lower balance functioning pre-AC. Larger, more representative studies of varying groups of participants are needed to further explore how this change relates to fall incidents and fall risk.</description><identifier>ISSN: 0031-5125</identifier><identifier>EISSN: 1558-688X</identifier><identifier>DOI: 10.1177/0031512517721069</identifier><identifier>PMID: 28728460</identifier><language>eng</language><publisher>Los Angeles, CA: SAGE Publications</publisher><subject>Aged ; Aged, 80 and over ; Aging - drug effects ; Aging - physiology ; Alcohol Drinking - blood ; Alcohol Drinking - physiopathology ; Alcohol use ; Female ; Humans ; Male ; Older people ; Postural Balance - drug effects ; Postural Balance - physiology ; Posture</subject><ispartof>Perceptual and motor skills, 2017-10, Vol.124 (5), p.912-931</ispartof><rights>The Author(s) 2017</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c365t-e959b2921f9baea4036c5be141de96d380d4369562ce3910117a8739ec51d9ed3</citedby><cites>FETCH-LOGICAL-c365t-e959b2921f9baea4036c5be141de96d380d4369562ce3910117a8739ec51d9ed3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://journals.sagepub.com/doi/pdf/10.1177/0031512517721069$$EPDF$$P50$$Gsage$$H</linktopdf><linktohtml>$$Uhttps://journals.sagepub.com/doi/10.1177/0031512517721069$$EHTML$$P50$$Gsage$$H</linktohtml><link.rule.ids>314,780,784,21819,27924,27925,43621,43622</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/28728460$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Wu, Helen Z.</creatorcontrib><creatorcontrib>Barry, Lisa C.</creatorcontrib><creatorcontrib>Duan, Yinghui</creatorcontrib><creatorcontrib>Bohannon, Richard W.</creatorcontrib><creatorcontrib>Covault, Jonathan M.</creatorcontrib><creatorcontrib>Grady, James J.</creatorcontrib><title>Acute Effects of Moderate Alcohol Consumption on Postural Stability in Older Adults</title><title>Perceptual and motor skills</title><addtitle>Percept Mot Skills</addtitle><description>This study involved healthy community-living older adults in an investigation of the association between moderate alcohol consumption (AC) and acute changes in postural stability and whether the association differed according to pre-AC balance skills.
