Alcohol use disorders (AUD) occur frequently in sexual minority (SM) adults (identifying as gay, lesbian or bisexual). Age-specific prevalence estimates, particularly during middle and older ages, remain obscure. With questions for sexual identity recently included in the National Survey of Drug Use and Health (NSDUH), increased precision is possible. This study investigates the age-specific estimate for AUD in sexual minority versus sexual majority adults.
Analysis of the 2015-2017 NSDUH, ages 18-years-and-older (N = 128,740). We estimate age-specific, 12-month DSM-IV AUD prevalence and adjusted prevalence ratios (via Poisson regression) by sexual identity. Adjusted models control for demographic, social, and mental health variables. Post-hoc analysis included age-specific estimates after redefining SM to include any same-sex attraction.
The age-specific estimate showed peak AUD prevalence at age ∼28 for all SMs, compared to age ∼23 for heterosexuals. By subgroup, gay men ages 18-23, had the highest AUD prevalence at 18.8% (CI: 13.5%, 25.5%). Bisexual women ages 24-29 had the highest disparity, a prevalence ratio (reference heterosexual women) of 2.59 (CI: 2.15, 3.13). Above age 50, the definition of SM is salient: in this age group, prevalence of AUD converges for heterosexuals and SMs that include individuals with any same-sex attraction.
In this largest study to date, SMs have a high prevalence of AUD. A disparity in the age-by-age estimates emerges by age 25 when AUD occurrence declines in heterosexuals but increases in SMs. A prevalence disparity occurs with each successive age strata, but by age 50-and-older, the difference is null.
性少数群体（同性恋、双性恋或无性恋）的成年人中经常出现酒精使用障碍（AUD）。特定年龄的患病率估计值，尤其是在中年和老年时期，仍然不清楚。由于最近在国家药物使用和健康调查（NSDUH）中纳入了性身份问题，因此可以提高精确度。本研究调查了性少数群体与性多数群体成年人中特定年龄的 AUD 估计值。
对 2015-2017 年 NSDUH 进行分析，年龄在 18 岁及以上（N=128740）。我们通过性身份估计了特定年龄的 12 个月 DSM-IV AUD 患病率和调整后的患病率比（通过泊松回归）。调整后的模型控制了人口统计学、社会和心理健康变量。事后分析包括重新定义性少数群体以包括任何同性吸引力后的特定年龄估计值。
特定年龄的估计表明，所有性少数群体的 AUD 患病率峰值出现在 28 岁左右，而异性恋者出现在 23 岁左右。按亚组划分，18-23 岁的男同性恋者 AUD 患病率最高，为 18.8%（95%CI：13.5%，25.5%）。24-29 岁的双性恋女性差异最大，患病率比（参考异性恋女性）为 2.59（95%CI：2.15，3.13）。50 岁以上，性少数群体的定义很重要：在这个年龄组中，异性恋者和包括任何同性吸引力个体的性少数群体的 AUD 患病率趋于一致。
在迄今为止最大的这项研究中，性少数群体的 AUD 患病率很高。到 25 岁时，异性恋者的 AUD 发生率下降，而性少数群体的 AUD 发生率上升，这种年龄估计的差异就会出现。随着年龄的增长，这种患病率差异会持续存在，但到 50 岁及以上，这种差异就会消失。
