To examine temporal changes in the number and demographic composition of transgender/gender non-binary (TGNB) population using data from integrated health care systems.
Electronic health records from Kaiser Permanente health plans in Georgia and Northern and Southern California were used to identify TGNB individuals, who sought care from January 2006 to December 2014, and the data were analyzed by year, site, age, and sex assigned at birth.
In 2006, the number of TGNB people (and corresponding 95% CI) per 100 000 population were 3.5 (1.9, 6.3) in Georgia, 5.5 (4.8, 6.4) in Southern California, and 17 (16, 19) in Northern California. In 2014, these frequencies increased to 38 (32, 45), 44 (42, 46), and 75 (72, 78) per 100 000 population, respectively. When analyzed by age, the most rapid increase was observed among persons 18 to 25 years old, and this increase accelerated after 2010. The ratio of transmasculine to transfeminine persons also changed from 1:1.7 in 2006 to 1:1 in 2014 overall and from 1:1 in 2006 to 1.8:1 in 2014 among persons <18 years of age.
This analysis confirms previous observations that the proportion of TGNB people is growing, especially among young adults. The composition of the TGNB population is also changing from predominantly transfeminine to roughly 1:1 overall and to predominantly transmasculine in children and adolescents.
利用综合医疗保健系统的数据，研究跨性别/性别不符合（TGNB）人群数量和人口构成的时间变化。
使用佐治亚州、加利福尼亚州北部和南部 Kaiser Permanente 健康计划的电子健康记录，来识别跨性别/性别不符合者。他们于 2006 年 1 月至 2014 年 12 月寻求医疗服务，通过年份、地点、出生时的年龄和性别进行数据分析。
2006 年，每 100000 人中有 TGNB 人数（95%CI）分别为佐治亚州 3.5（1.9，6.3）、南加州 5.5（4.8，6.4）和北加州 17（16，19）。到 2014 年，这些频率分别增加到 38（32，45）、44（42，46）和 75（72，78）。按年龄分析，18 至 25 岁的人群增长最快，2010 年后增速加快。跨男性化和跨女性化人群的比例也从 2006 年的 1:1.7 总体上转变为 1:1，18 岁以下人群从 2006 年的 1:1 转变为 2014 年的 1.8:1。
这项分析证实了之前的观察结果，即跨性别/性别不符合者的比例在增长，尤其是在年轻成年人中。TGNB 人群的构成也在发生变化，从主要是跨女性化转变为总体上大致 1:1，在儿童和青少年中则主要是跨男性化。
