We explored the effect of thin ideal internalisation, shame proneness and family criticism on disordered eating and suicidal intent in female Mexican adolescents.
We studied a probabilistic sample of 2537 high school students in central Mexico, stratified by marginalisation status and migratory intensity. We used a generalised logistic regression model to estimate the odds of disordered eating and suicidal intent across scores for three predictors: Internalisation of the thin ideal, shame and family criticism.
Disordered eating was reported by 4.2% (95% CI = 0.9-7.5%) and suicidal intent by 13.2% (95% CI = 12.0-14.4%) of girls. The unadjusted odds ratios of any disordered eating for thin ideal internalisation, shame proneness and familial criticism were 1.2, 1.1 and 3.2, respectively. The positive association between thin ideal internalisation and disordered eating remained even after controlling for shame proneness and familial criticism. The association of these variables with suicidal intent was weaker.
Results support stronger effects for disordered eating than suicidal intent across the three unadjusted predictors. It also highlights the presence of the relationship of criticism and disordered eating in female adolescents from low and middle socio-economic backgrounds.
我们探讨了理想化体型内化、易羞耻和家庭批评对墨西哥青春期女性饮食失调和自杀意念的影响。
我们对墨西哥中部的一个概率抽样的 2537 名高中生进行了研究，按照边缘化程度和移民强度进行分层。我们使用广义逻辑回归模型来估计三个预测因子（理想化体型内化、羞耻和家庭批评）的分数与饮食失调和自杀意念的几率之间的关系。
4.2%（95%置信区间：0.9-7.5%）的女孩报告有饮食失调，13.2%（95%置信区间：12.0-14.4%）的女孩有自杀意念。未经调整的比值比（OR）表明，在理想化体型内化、易羞耻和家庭批评的情况下，任何饮食失调的几率分别为 1.2、1.1 和 3.2。即使在控制了易羞耻和家庭批评之后，理想化体型内化与饮食失调之间的正相关关系仍然存在。这些变量与自杀意念的关联则较弱。
结果支持在未经调整的三个预测因子中，饮食失调的影响大于自杀意念。它还强调了在社会经济背景较低的青春期女性中，批评与饮食失调之间存在关系。
