ObjectiveThis systematic review aims to identify and evaluate the literature investigating protective factors and eating disorders (EDs), to establish what is known about factors in family systems that could be considered protective against the development of ED/disordered eating.MethodsA systematic review of the literature was conducted on five databases, using search terms related to ED/disordered eating and protective factors. Studies were systematically screened and included if they made reference to a protective factor within the family system and explored associations with a quantitative measure of ED/disordered eating behaviours. All included studies were evaluated for study quality.ResultsTwenty-five studies met criteria for inclusion. Ten papers made use of longitudinal or prospective designs appropriate to identify factors potentially protecting against the development of disordered eating difficulties, while a further 15 papers report cross-sectional associations between family factors and disordered eating outcomes. Studies looked at aspects of family relationships and family practices around food or eating. There was a particular research focus on the potential protective role of regular family meals.Conclusions and ImplicationsMany of the potential protective factors identified, such as family support and connectedness, may be non-specific to eating difficulties, promoting general adaptive development and a range of positive development outcomes. Factors in the family environment around food, eating and weight, such as frequent family meals and avoiding comments about weight, may be more specific to ED and disordered eating. Issues with the methodologies used severely impact on the ability to draw conclusions about whether factors are ‘protective’.
Background Siblings of people with anorexia nervosa (AN) have been found to experience strong emotions, changing family roles and poorer wellbeing as a consequence of experiencing the effects of the illness on their sibling and family system. These factors, combined with genetic influences, may put siblings at an increased risk of developing eating disorder psychopathology in addition to other mental health issues. This research aims to explore the experiences of siblings of people with AN who have had eating difficulties themselves and investigate issues that may be important to the development and prevention of eating difficulties in this population. Methods This qualitative study used a reflexive thematic analysis approach. Ten adults who had witnessed a sibling with AN and experienced eating difficulties themselves participated in semi-structured interviews. Analysis Participants’ own eating difficulties were affected by the specific experience of witnessing a sibling with AN through mealtimes becoming emotionally charged, an increased focus on body size and diet, and comparisons with their sibling. Difficult experiences, such as marital discord amongst parents were common, as was a difficulty in managing emotions. The onset of AN within the family caused participants to take on caring responsibilities for their sibling and to hide their own difficulties for fear of adding additional burden to their parents. This reduced their perceived ability to access support and for some increased a desire to restrict as a coping mechanism for the stress they were experiencing. Systemic beliefs regarding the value of thinness were prevalent and influential. Protective factors, such as not wanting to become as unwell as a sibling with AN and an understanding of the negative consequences of AN, aided recovery. Conclusions Eating difficulties in siblings of people with AN may be influenced by competition for slimness, increased focus on diet and body size, and a need to manage difficult emotions. The disruption to social connections and a difficulty finding emotional support that may be experienced by people when a sibling develops AN may further influence susceptibility to eating difficulties. Further research is needed into the best ways to support siblings of people with AN.

Changing family roles following their sibling’s illness could have influenced the development of eating difficulties, and limited participants’ ability to access support for their own difficulties. Systemic beliefs regarding the value of thinness were prevalent and influential.
