Abstract
Eating disorders and weight problems across the life span have been linked to adverse childhood experiences. Previous research often focused on child abuse and omitted investigating effects of child neglect. The present study evaluates effects of neglect on bodyweight across the life span and how emotional neglect and bodyweight are linked via mental distress. Within a large survey representative of the German population (N = 2,500), individuals completed measures of mental distress, childhood trauma, and height and weight. We conducted logistic regression analyses on bodyweight extremes and a moderated mediation analysis. In men, physical neglect aggravated the risk to be underweight. In women, emotional neglect was linked to severe obesity. In both sexes, emotional neglect was related to mental distress. We found an indirect effect of emotional neglect on bodyweight via mental distress, however, it was only present in women. Our results attest to long-term consequences of adverse early experiences. We showed a possible mechanism for women's higher vulnerability towards eating disorders. In general, investigations of eating and weight disorders should also include men and employ sex-specific methods of analyses. Lastly, neglect should also receive more attention to prevent suffering and negative sequelae over the life span.Entities:

Note. EN: Emotional neglect according to the CTQ (range 5–25). Income: Equivalised income calculated according to the OECD guideline[67]: household income/√(people in household); household income per month: 1 = < 1,250€, 2 = 1,250–2500€, 3 = > 2,500€. N = 2,404.
Figure 2Depiction of the unmediated effect of emotional neglect on bodyweight (model 0, top), and the full moderated mediation model (model 2, bottom). The effect was partially mediated by distress, so that the direct effect (b = 0.098, p < 0.001) observed in model 0 was smaller in model 2 (b = 0.079, p = 0.005).
Figure 3Association of mental distress and BMI as a function of sex: The drawn through line represents a significant positive association between distress and BMI among women (b = 0.328 [95% CI 0.215–0.441], p < 0.001). The dotted line indicates a nonsignificant association of BMI and distress among men (b = −0.022 [95% CI −0.163–0.120], p = 0.764).
Figure 4Scatter plots with fitted curves (linear and quadratic) depicting the relationship of mental distress and BMI in men and women. A two-way ANOVA of sex and mental distress on BMI yielded a significant interaction of the fixed effects sex and mental distress (model: F(3) = 14.382, p < 0.001. mental distress: F(1) = 9.768, p < 0.001; sex: F(1) = 1.918, p < 0.001, mental distress by sex: F(1) = 11.544, p < 0.001).
