New ACBRD research highlights the link between weight self-stigma, healthy eating, and physical activity among Australian adults with type 2 diabetes
Living with type 2 diabetes can come with many challenges. Many people struggle with concerns about their weight and face stigma because of their body shape / size. This stigma can include negative judgments from others, being treated differently, and self-stigma. Weight self-stigma is when people feel a sense of shame or embarrassment about their weight and internalise others’ judgments. This blame and shame can make it harder to manage diabetes.
A study led by Sarah Manallack at the ACBRD explored the link between weight self-stigma and self-care. We surveyed 726 adults with type 2 diabetes who were concerned about their weight. We measured weight self-stigma and self-care habits (like heathy eating and exercise). We also explored the role of self-esteem, confidence in managing diabetes, and social support.
We found that weight-self-stigma is common. Almost all participants (91%) reported experiencing some form of weight self-stigma. Those who experienced more stigma were also less likely to eat healthily and exercise regularly. This is concerning because healthy eating and physical activity are essential for good health and diabetes management.
The study also highlighted the importance of self-esteem, confidence and social support in coping with stigma. People with higher self-esteem, confidence in managing diabetes, and social support reported lower self-stigma and healthier habits.
Weight stigma is a real barrier to diabetes self-management. Managing type 2 diabetes involves making daily choices about food, exercise, and medication. When people feel ashamed, they may not engage in healthy behaviours.Addressing weight stigma could lead to better health outcomes for people with type 2 diabetes. These findings highlight the need for more inclusive and supportive diabetes care. Reducing weight self-stigma could improve emotional well-being and help people with diabetes adopt healthier habits. This shift could make a big difference in how we support individuals living with type 2 diabetes, particularly those facing weight-related stigma.
As a community, we must work together to reduce stigma, and create healthier, more supportive environments for those managing diabetes.
