This study aimed to provide hazardous and binge drinking prevalence, odds and risk attributable to specific demographic correlates in community dwelling older adults using both the standard and new older-specific AUDIT-C thresholds.
Hazardous drinking was assessed using the AUDIT-C in a cross-sectional postal survey of 6662 New Zealanders aged 55-70 years old (m=60.94, SD=4.70) randomly selected from the New Zealand Electoral Roll. Prevalence data is presented for whole sample and stratified by key demographic correlates using standard and older-specific threshold scores on the AUDIT-C. Hazardous drinking prevalence using the standard AUDIT-C threshold was 56.01%, as compared to 42.28% and 50.20% under two older-specific thresholds.
Being younger, male, and wealthy were consistent drinking predictors across thresholds but the older-specific thresholds substantially altered the prevalence and risk for females, Asians, and poorer people. Past-month binge prevalence of 18.18% was considerably lower than the past-year prevalence of 33.51%, but change from past-month to past-year binge threshold had no significant effect on the demographic composition of binge drinkers. The standard AUDIT-C threshold over-estimates hazardous drinking prevalence in older adults by up to 33%, but even the most conservative rates in this study are cause for concern regarding the level of drinking by older people in New Zealand.
Older hazardous drinkers are predominantly younger, wealthier, white, partnered males, whichever threshold is used, but binge drinkers are more likely to be rural, Māori, and lack tertiary education. Further efforts are needed to determine factors underpinning hazardous drinking, especially in older Māori.
本研究旨在使用标准和新的老年专用 AUDIT-C 阈值，为居住在社区中的老年成年人提供危险和 binge 饮酒的流行率、几率和归因于特定人口统计学相关性的风险。
在一项针对 6662 名年龄在 55-70 岁（m=60.94，SD=4.70）的新西兰人进行的横断面邮寄调查中，使用 AUDIT-C 评估危险饮酒。使用 AUDIT-C 的标准和老年专用阈值，为整个样本和按关键人口统计学相关性分层的样本提供流行率数据。使用标准 AUDIT-C 阈值，危险饮酒的流行率为 56.01%，而使用两个老年专用阈值，危险饮酒的流行率分别为 42.28%和 50.20%。
年轻、男性和富有是所有阈值下一致的饮酒预测因素，但老年专用阈值极大地改变了女性、亚洲人和较贫穷人群的流行率和风险。过去一个月 binge 饮酒的流行率为 18.18%，明显低于过去一年的 33.51%，但从过去一个月到过去一年 binge 阈值的变化对 binge 饮酒者的人口统计学构成没有显著影响。标准 AUDIT-C 阈值高估了老年成年人的危险饮酒流行率，最高可达 33%，但即使在本研究中最保守的比率也令人担忧新西兰老年人的饮酒水平。
无论使用哪个阈值，老年危险饮酒者主要是年轻、富有、白人、已婚男性，但 binge 饮酒者更有可能来自农村地区、毛利人，且缺乏高等教育。需要进一步努力确定危险饮酒的根本原因，特别是在老年毛利人中。
