Prevalence and concordance of cardiometabolic risk markers and health behaviour among couples after a gestational diabetes mellitus-affected pregnancy.

aimsThis study investigated the prevalence and concordance of cardiometabolic risk markers among couples after a gestational diabetes mellitus (GDM)-affected pregnancy. It also examined whether selected demographic, socioeconomic and health behavioural factors could explain within-couple associations. MATERIALS AND

methodsA cross-sectional study design was used. We included health examinations and questionnaire data from couples assessed 12 weeks after a pregnancy affected by GDM. We determined the prevalence and concordance of cardiometabolic risk markers (overweight or obesity, high waist circumference, metabolic syndrome, impaired fasting glucose [≥6.1 mmol/L], and stage 1 hypertension or more [≥130 mmHg/≥80 mmHg], along with health behaviour [dietary quality and physical activity]).

resultsA total of 196 couples were included. Overweight or obesity was present in 63.3% of women and 71.9% of partners, with concordance observed in 50.5% of couples. By comparison, 78.6% of women and 55.1% of partners had high waist circumferences, which was concordant in 48.5% of couples. Metabolic syndrome was identified in 9.2% of women and 24.0% of partners, suggesting a higher occurrence among partners with concordance in 5.1% of couples. Impaired fasting glucose was observed in 7.7% of women and 9.2% of partners, with concordance in 1.5% of couples. Stage 1 hypertension or more was observed in 31.1% of the women, 55.6% of the partners and concordant in 8.2% of couples. Cardiometabolic risk markers were associated within couples.

conclusionsDetecting GDM in women may serve as an opportunity to identify partners at risk, underscoring the potential of couple-based or family-focused interventions.
