Western society has become increasingly obesogenic. Despite this trend, some individuals maintain low weights throughout their lives. Little is known about the characteristics of persistently thin individuals. This study examined demographic, health, and psychiatric characteristics of women who reported having been persistently thin throughout childhood, adolescence, and adulthood.
Participants were 1022 female members of a population-based twin registry. Participants completed a mail survey that included questions regarding demographics, body size in childhood, adolescence, and adulthood, health behaviors and satisfaction, disordered eating, perfectionism, and personality. In previous interview waves, participants completed diagnostic interviews assessing psychiatric and substance use disorders.
Persistent thinness was associated with a significantly later age at menarche, lower rates of dieting and binge eating, greater health satisfaction, higher self-esteem, and lower perfectionism and body dissatisfaction.
Persistent thinness appears to be associated with greater well-being in the present and a later age of menarche in the past. Whether later menarche is causally related to thinness or whether later menarche, persistent thinness, and enhanced well-being all result from a third unmeasured variable such as high sports participation is yet to be resolved.
西方社会的致肥胖因素日益增多。尽管有这一趋势，但仍有一些人一生都保持低体重。对于一直很瘦的人的特征，人们了解甚少。本研究调查了那些报告自己在童年、青少年期和成年期一直很瘦的女性的人口统计学、健康和精神特征。
参与者是一个基于人群的双胞胎登记处的1022名女性成员。参与者完成了一项邮寄调查，其中包括有关人口统计学、童年、青少年期和成年期的体型、健康行为与满意度、饮食失调、完美主义和性格等问题。在之前的访谈阶段，参与者完成了评估精神疾病和物质使用障碍的诊断访谈。
持续消瘦与月经初潮年龄显著更晚、节食和暴饮暴食发生率更低、更高的健康满意度、更高的自尊以及更低的完美主义和身体不满相关。
持续消瘦似乎与当前更高的幸福感以及过去更晚的月经初潮年龄相关。月经初潮较晚是否与消瘦存在因果关系，或者月经初潮较晚、持续消瘦和幸福感增强是否都源于第三个未测量的变量，如高体育参与度，仍有待解决。
