Seasonal Changes in the Prevalence of Gestational Diabetes Mellitus

Journal Article


Abstract


  • OBJECTIVE

    To determine the effect of different seasons on the prevalence of gestational

    diabetes mellitus (GDM) by using World Health Organization criteria.

    RESEARCH DESIGN AND METHODS

    The results of all pregnancy glucose tolerance tests (GTTs) were prospectively

    collected over a 3-year period in a temperate climate, and the results were

    grouped by season.

    RESULTS

    The results of 7,369 pregnancy GTTs were available for consideration. In winter, the

    median 1-h and 2-h glucose results after GTT were significantly (P < 0.0001) lower

    than the overall 1-h and 2-h results. The prevalence ofGDMat the 1-h diagnostic level

    was 29% higher in summer and 27% lower in winter than the overall prevalence (P =

    0.02). The prevalence of GDM at the 2-h diagnostic level was 28% higher in summer

    and 31% lower in winter than the overall prevalence (P = 0.01).

    CONCLUSIONS

    The prevalence of GDM varies according to seasons, which leads to the possible

    overdiagnosis of GDM in summer and/or underdiagnosis in winter. Further research

    into standardization of the GTT or seasonal adjustment of the resultsmay need to be

    considered.
