Breastfeeding Goal Attainment And Likelihood Of Future Breastfeeding: A Test Of Self-Affirmation Theory, Mackenzie Dm Whipps

Health Behavior Research

Breastfeeding is an important health behavior for pediatric and maternal wellbeing. However, many mothers in the United States do not meet breastfeeding duration guidelines, nor do they meet their own goals for breastfeeding. Non-attainment of breastfeeding goals has implications for the health and wellbeing of future children born into those families. Using publicly available national data, we tested a self-affirmation theory (SAT) hypothesis to explore the complex relationship between breastfeeding goal attainment and intention to breastfeed a future child. We found goal attainment predicted stronger future intention, and that this association was moderated by how highly the mother valued breastfeeding. …

Physical Activity Behavior Comparisons Between Adults With And Without Type 1 Diabetes, Cassandra M. Beattie, Jesse A. Stein, Katie Heinrich

Health Behavior Research

Physical activity (PA) is a widely accepted strategy to manage chronic diseases like type 1 diabetes; however, unique PA barriers likely result in lower PA levels among person(s) with type 1 diabetes (PWT1D), compared to person(s) without type 1 diabetes (PWOT1D). The integrated theory of health behavior change (ITHBC) (i.e., knowledge/beliefs, self-regulation, and self-management) provides a helpful framework for understanding PA and other health behaviors. This research aimed to determine differences in PA between adult PWT1D and PWOT1D, and characterize their PA-related behaviors using the ITHBC. Participants (N = 90; 86.7% female, 90% white) were recruited via social media …
