Background Affection exchange theory (AET) explains the value of received affection for overall wellbeing in family relationships. However, this study extends prior work by investigating AET in grandmother-grandchild relationships and grandchildren’s individual well-being. This study seeks to understand the relationships between adult grandchildren’s received grandmother affection and health-related behaviors such as diet, exercise, substance abuse, and sleep. Methods This cross-sectional study included 229 university student participants. Multiple regression analyses were performed to analyze received grandmother affection and grandchildren’s health behaviors. Results Using cross-sectional survey methods, it was found that grandchildren’s reports of received memories and humor, and celebratory affection influenced grandchildren’s dietary behaviors. Received love and esteem, memories and humor, and celebratory affection was also associated with grandchildren’s exercise behaviors. Conclusions Grandchildren who receive grandmother affection may be likely to engage in the well-being process by engaging in health behaviors, while those who are not receiving affection might suffer the health consequences in adulthood. These findings support the assumption of affection exchange theory that received family affection, in this case, grandmother affection leads to positive health outcomes such as enhanced dietary and exercise behaviors among grandchildren.
