The aim of this study was to explore the temporal development of beliefs about health, illness and health care in migrant women with gestational diabetes (GD) born in Asia residing in Sweden, and the influence on health-related behaviour in terms of self-care and seeking care.

Migrant Asian women are a high-risk group for developing GD. Adapting to the culture in the new society and the healthcare system, being diagnosed with GD and becoming a mother is demanding. The question is whether Asian migrants’ patterns of beliefs and behaviour change over time, as no previous study has been revealed on this topic.

Qualitative prospective exploratory study. Semi-structured interviews were held on three occasions: during pregnancy and three and fourteen months after delivery, with women born in Asia, diagnosed with GD. Data were analysed with qualitative content analysis.

There was a temporal change of beliefs influencing health-related behaviour, showing a rising curve in risk awareness. An increasing number of persons described developing a healthy diet/lifestyle based on initial advice and shifted focus from the child to worries about the woman’s health and risk of developing type 2 diabetes and being unable to care for the child/family. Also, the number of women perceiving GD as a transient condition decreased and more believed it would last forever. Beliefs about health care were unchanged, the healthcare model was perceived working well but information about GD and follow-ups was requested even after delivery, and competent staff was expected. Health professionals’ beliefs about the seriousness of GD influence patients’ beliefs and need to be considered. Migrant women need support with adequate information, based on their individual beliefs, to continue develop a sustainable healthy lifestyle even after giving birth, to promote health and prevent type 2 diabetes.

No previous studies have been found focusing on the long-term development of beliefs about health, illness and healthcare in migrant women with gestational diabetes mellitus (GDM). The aim of this study was to explore this and the influence on health-related behaviour (i.e. self-care and care seeking) in migrant women from the Middle East living in Sweden seven years after delivery.

GDM is increasing, particularly in migrant women. The risk of adverse outcomes of GDM for health can be improved by interventions reducing blood glucose and lifestyle modifications which medicalise the woman’s pregnancy due to intensive follow-up and demanding self-care. The reactions might have an enduring impact on the women’s long-term psychological and physical health and adoption of preventive health behaviours.

Qualitative exploratory study. Semi-structured follow-up interviews 7 years after delivery with women previously interviewed in gestational weeks 34–38 and 3 and 14 months after delivery. Data analysed with qualitative content analysis.

Health meant freedom from illness, feeling well and living long to be able to care for the children. The present situation was described either positively, changing to a healthier lifestyle, or negatively, with worries about being affected by type 2 diabetes. Beliefs changed among the majority of women, leading to a healthier lifestyle, and they looked positively back at the time when diagnosed and their reactions to it. With few exceptions, they were confident of being aware of future health risks and felt responsible for their own and their children’s health/lifestyle. None except those diagnosed with type 2 diabetes had been in contact with healthcare since the last follow-up a year after delivery. Yet, they still would like and need a healthcare model delivering more information, particularly on developing a healthy lifestyle for children, and with regular check-ups also after the first year after delivery.
