Disordered eating behaviors (DEBs) and adolescent pregnancy are public health problems. Among adolescents, there is little evidence concerning the relationship of DEB with gestational weight gain (GWG) and the birth weight and length of their offspring. We aimed to determine the association between DEB with GWG and the weight and length of adolescents' offspring. We conducted a study with 379 participants. To evaluate DEB, we applied a validated scale. We identified three factors from DEB by factorial analysis: restrictive, compensatory, and binge-purge behaviors. The main events were GWG and offspring's birth weight and length. We performed linear regression models. We found that 50% of adolescents have at least one DEB. Excessive and insufficient GWG were 37 and 34%, respectively. The median GWG was 13 kg; adolescents with restrictive behaviors had higher GWG (13 vs. 12 kg, = 0.023). After adjusting for pregestational body mass index and other covariables, the restrictive (β = 0.67, = 0.039), compensatory (β = 0.65, = 0.044), and binge-purge behaviors (β = 0.54, = 0.013) were associated with higher GWG. We did not find an association between the birth weight and length of newborns with DEB, and suggest that DEB is associated with GWG but not with the birth weight or length of the offspring.
饮食失调行为（DEB）和青少年怀孕是公共卫生问题。在青少年中，关于 DEB 与妊娠体重增加（GWG）以及他们后代的出生体重和长度的关系的证据很少。我们旨在确定 DEB 与 GWG 以及青少年后代的体重和长度之间的关系。我们进行了一项有 379 名参与者的研究。为了评估 DEB，我们应用了经过验证的量表。我们通过因子分析确定了 DEB 的三个因素：限制、补偿和暴食-清除行为。主要事件是 GWG 和后代的出生体重和长度。我们进行了线性回归模型分析。我们发现，50%的青少年至少有一种 DEB。过度和不足的 GWG 分别为 37%和 34%。GWG 的中位数为 13 公斤；有节制行为的青少年 GWG 更高（13 公斤与 12 公斤， = 0.023）。在校正了孕前体重指数和其他协变量后，限制（β = 0.67， = 0.039）、补偿（β = 0.65， = 0.044）和暴食-清除行为（β = 0.54， = 0.013）与更高的 GWG 相关。我们没有发现 DEB 与新生儿出生体重和长度之间的关系，这表明 DEB 与 GWG 相关，但与后代的出生体重或长度无关。
