The specific QOL questionnaire for women with GDM (GDMQ‑36) and the demographic questionnaire were completed for participants. Independent variables were entered into the multiple linear regression model and were analyzed.</p><p><strong>Results: </strong>The total Mean(SD) score of the QOL of mothers with GDM who participated in the study was 46.83 (11.66) based on percentage. The highest and lowest QOL Mean (SD) scores were obtained on the support 76.50 (14.50) and concerns about a high‑risk pregnancy 31.40 (19.80), subscales, respectively. The total QOL score decreased by 7.14 and 5 points on average in mothers treated with medication regimens and mothers who had a pre‑high school education, respectively.
