Developing inclusive care to support women to manage gestational diabetes and reduce future type 2 diabetes risk: A behavioural analysis using the COM-B model
This study utilizes the COM-B model to analyze interviews with 35 diverse women, identifying specific capability, opportunity, and motivation barriers to gestational diabetes self-management and type 2 diabetes prevention, thereby providing a theoretical foundation for developing inclusive, behaviorally-informed interventions.

Pregnancy is a time of profound biological change, yet for some women, it also brings a specific medical challenge: gestational diabetes. This condition occurs when blood sugar levels rise during pregnancy, a state that, if left unmanaged, can pose serious risks to both mother and child, including premature birth and complications during delivery. The story does not end with the birth of the baby. For half of the women who experience this condition, the high blood sugar returns later in life as type 2 diabetes, a chronic disease that affects how the body processes energy. This future risk is not distributed equally; women from minority ethnic backgrounds face a significantly higher burden of the disease. While doctors know that changing one's diet and moving the body are the most effective ways to manage blood sugar during pregnancy and prevent the disease later, the path to making those changes is often blocked by invisible walls. These barriers are not just about willpower; they are woven into the fabric of daily life, cultural beliefs, and the way medical advice is delivered. Understanding exactly where these walls stand is the only way to build a bridge over them.
A team of researchers set out to map these barriers by listening directly to the women living through them. They conducted in-depth conversations with thirty-five women in the United Kingdom who had recently been diagnosed with gestational diabetes. The group was diverse, with two-thirds of the participants coming from minority ethnic backgrounds, including first-generation migrants from countries like Bangladesh, Pakistan, India, Nigeria, and Uganda. The researchers did not simply ask what the women did; they asked why it was hard or easy to do. They used a framework that breaks human behavior down into three parts: whether a person has the ability to do something, whether the environment allows them to do it, and whether they are motivated to do it. By applying this lens, the team moved beyond general complaints to identify the specific mechanics of why women struggle to manage their blood sugar and prevent future disease.
The study revealed that the struggle begins with a lack of clear, usable knowledge. Many women found the guidance they received from hospitals to be vague, generic, or outdated. One participant described being told to eat two satsumas as a snack, a suggestion that felt absurd to those who understood how sugar affects the body. Others felt overwhelmed by the technical skill required to test their blood sugar four times a day, a task that demanded precision and constant mental focus. For many, the instructions felt like a foreign language, and in the absence of clear, tailored advice, they turned to the internet, often finding conflicting or unreliable information. This gap in knowledge was compounded by a lack of practical resources; some women waited weeks for testing equipment, while others could not afford the cost of healthier foods or the time to prepare them amidst work and childcare.
Motivation, the internal drive to act, was often eroded by cultural beliefs and emotional weight. In some communities, the idea of restricting food during pregnancy was seen as harmful to the baby, and the safety of exercising while pregnant was questioned. For others, the diagnosis brought a heavy sense of guilt, as if the condition was a personal failure. The researchers found that when women felt judged by healthcare staff or felt their voices were ignored, their desire to follow the rules diminished. The emotional toll was real; the constant monitoring and pressure to be perfect created a cognitive overload that made the simple act of managing a meal feel impossible. Even when women wanted to do the right thing for their baby, the conflicting messages from their culture and their medical team left them paralyzed.
Once the baby was born, the challenges shifted but did not disappear. The study found that for many women, the diagnosis of gestational diabetes felt like a closed chapter. They did not see themselves as people at risk of developing type 2 diabetes later in life. This lack of identity as a "patient" meant that the motivation to maintain a healthy lifestyle faded quickly. The pressures of new motherhood, breastfeeding, and returning to work crowded out any time for self-care. For women from minority ethnic groups, the pressure to return to traditional diets high in carbohydrates was strong, often reinforced by family expectations. In some cultures, the prevalence of diabetes was so high that it was viewed as an inevitable part of life, a sentiment that reduced the urgency to change. The researchers noted that without clear, personalized data showing a woman her own risk, the future threat of diabetes remained an abstract concept rather than a personal reality.
The researchers did not just identify problems; they proposed specific ways to fix them based on what they learned. They suggested that medical advice needs to be far more practical and culturally relevant, offering concrete instructions on how to pair foods and exercise safely, rather than generic lists. They emphasized the need for emotional support, suggesting that healthcare teams should listen with empathy and that women should be connected with peers who understand their experience. For the postpartum period, the study argued that the system must actively remind women of their risk and provide clear, concise guidance on screening, rather than assuming they will remember or prioritize it on their own. The authors also highlighted that for women whose lives are deeply rooted in community traditions, the most effective support might come from trusted community figures and local organizations rather than hospitals alone.
Ultimately, this work paints a picture of a system that often fails to meet women where they are. The barriers to managing gestational diabetes and preventing future disease are not simply a matter of individual choice. They are structural, cultural, and psychological hurdles that require a tailored approach. The study suggests that by understanding the specific capabilities, opportunities, and motivations of diverse groups of women, healthcare providers can design support that is inclusive and effective. It is a call to move beyond a one-size-fits-all model and to build a system that recognizes the complex realities of the women it serves, ensuring that the path to health is open to everyone, regardless of their background or the challenges they face.
