Diet and physical activity changes among low-income families: perspectives of mothers and their children.

: The current study explored how mothers and their children influence each other's diet and physical activity. : We conducted semi-structured interviews with women with diabetes and their children ( = 18) from eight low-income families. : Two approaches to changes emerged: collaborative and non-collaborative. Families using collaborative approaches believed they could sustain positive changes through accepting family changes, encouragement, abstaining from buying certain foods, modelling and compromise. Within families using non-collaborative approaches, some challenges included using more individualistic approaches and poor communication. Lack of information and resource constraints challenged all families. : Interventions should reinforce family collaborative approaches and teach skills for families to work together towards a healthier lifestyle.
