Overweight and obesity constitute a major and increasing health and welfare problem throughout the world. Assessing the multifaceted mechanisms – biological, environmental and behavioural – behind this development is a crucial task in medical, social and economic sciences. We are, therefore, grateful to have been given the opportunity to, once again, discuss whether the risk of divorce may be one of the factors influencing the incentives of becoming overweight or obese and, hence, ultimately the physical appearance among the married. In this Debate, colleagues Schneider and Grimps present the results of a multilevel analysis, in which they could not identify any statistically significant association between body mass index (BMI) and divorce risk among married people. Thus, they question the findings, previously published in this Journal (Lundborg et al., 2007). The Schneider and Grimps arguments are not convincing, however. So, we still claim that the statistical material at hand does, indeed, imply that divorce risk at the national level may well influence the weight of the married.
