Underlying beliefs of preventive health behaviours among women with a history of gestational diabetes mellitus: A descriptive qualitative study

To explore the underlying beliefs of preventive health behaviours among women with a history of GDM who had low levels of preventive health behaviours during their postpartum period in Singapore. This paper reports on the qualitative arm of a mixed method study. The qualitative descriptive design was adopted. Individual interviews were conducted between 7th September 2020 and 25th September 2020 using a semi-structured interview guide. Data collected were analysed using thematic analysis. A total of 18 women completed the interview. The participants' ages ranged from 26 to 40 years with a mean age of 33.17 years (SD= 4.09). The duration since childbirth was 8.78 months (SD = 1.35). Through thematic analysis, five themes were developed: lifestyle adjustment, self-motivation, supportive environment, barriers to practising a healthy lifestyle, and risk perception. A total of 14 subthemes emerged from the five main themes. The beliefs of women with a history of GDM were described according to the Theory of Planned Behaviour. Having a newborn brings changes to the lifestyle of a woman and her family, which can affect the health behaviours in the postpartum period. This study revealed several novel findings relating to the unmet needs of women who had GDM, specifically to the need for information and emotional support to safely resume healthy behaviours after childbirth, for which participants have provided suggestions on how to enhance the continuity of care in the postpartum period.
