Delayed puberty is a common condition defined as the lack of sexual maturation by an age ≥2 SD above the population mean. In the absence of an identified underlying cause, the condition is usually self-limited. Although self-limited delayed puberty is largely believed to be a benign developmental variant with no long-term consequences, several studies have suggested that delayed puberty may in fact have both harmful and protective effects on various adult health outcomes. In particular, height and bone mineral density have been shown to be compromised in some studies of adults with a history of delayed puberty. Delayed puberty may also negatively affect adult psychosocial functioning and educational achievement, and individuals with a history of delayed puberty carry a higher risk for metabolic and cardiovascular disorders. In contrast, a history of delayed puberty appears to be protective for breast and endometrial cancer in women and for testicular cancer in men. Most studies on adult outcomes of self-limited delayed puberty have been in small series with significant variability in outcome measures and study criteria. In this article, we review potential medical and psychosocial issues for adults with a history of self-limited delayed puberty, discuss potential mechanisms underlying these issues, and identify gaps in knowledge and directions for future research.
青春期延迟是一种常见病症,定义为性成熟年龄比人群均值高出≥2个标准差。在未发现潜在病因的情况下,该病通常为自限性。尽管人们普遍认为自限性青春期延迟是一种良性发育变异,不会产生长期后果,但多项研究表明,青春期延迟实际上可能对各种成人健康结局既有有害影响,也有保护作用。特别是,在一些针对有青春期延迟病史的成年人的研究中,身高和骨矿物质密度已被证明受到影响。青春期延迟还可能对成人的心理社会功能和学业成绩产生负面影响,有青春期延迟病史的个体患代谢和心血管疾病的风险更高。相比之下,青春期延迟病史似乎对女性的乳腺癌和子宫内膜癌以及男性的睾丸癌具有保护作用。大多数关于自限性青春期延迟成人结局的研究都是小规模系列研究,结局指标和研究标准差异很大。在本文中,我们回顾了有自限性青春期延迟病史的成年人潜在的医学和心理社会问题,讨论了这些问题背后的潜在机制,并确定了知识空白和未来研究方向。
