Puberty marks a transition in risk for body image disturbance and disordered eating. Yet few studies have examined these symptoms across puberty and none have examined links with adrenarche, the earliest phase in the pubertal hormonal cascade.
Levels of adrenal androgens (dehydroepiandrosterone, dehydroepiandrosterone sulphate, and testosterone) were measured in a population-based study of 8- to 9-year-old children (516 males and 621 females). Body dissatisfaction was measured using the Kids' Eating Disorder Scale Silhouettes. Covariates included body mass index, age, and socioeconomic status.
There were significant associations between adrenal androgen levels and greater body dissatisfaction in both males and females. Specifically, females with more advanced levels of dehydroepiandrosterone and testosterone relative to peers, and males with more advanced levels of testosterone relative to peers, reported greater body dissatisfaction. However, after adjusting for covariates, hormones levels were no longer associated with body dissatisfaction, and only higher body mass index had a clear association with body dissatisfaction.
The adrenarchal transition brings a heightened risk for body dissatisfaction. Whether this arises from the neuroendocrine effects of adrenal androgens or as a reaction to the greater body mass that accompanies adrenarche requires further exploration.
青春期是身体意象障碍和饮食失调风险增加的一个过渡时期。然而,很少有研究在整个青春期阶段研究这些症状,也没有研究这些症状与肾上腺功能初现(青春期激素级联的最早阶段)之间的联系。
在一项针对 8 至 9 岁儿童(516 名男性和 621 名女性)的基于人群的研究中,测量了肾上腺雄激素(脱氢表雄酮、硫酸脱氢表雄酮和睾酮)的水平。使用儿童饮食失调量表剪影来测量身体不满。协变量包括体重指数、年龄和社会经济地位。
在男性和女性中,肾上腺雄激素水平与更高的身体不满之间存在显著关联。具体来说,与同龄人相比,脱氢表雄酮和睾酮水平较高的女性,以及与同龄人相比,睾酮水平较高的男性,报告的身体不满程度更高。然而,在调整了协变量后,激素水平与身体不满不再相关,只有更高的体重指数与身体不满有明显的关联。
肾上腺功能初现的过渡带来了更高的身体不满风险。这种风险是由于肾上腺雄激素的神经内分泌作用引起的,还是由于伴随肾上腺功能初现而来的更大的体重增加引起的,需要进一步探讨。
