[SLEEP DISTURBANCES AND GESTATIONAL DIABETES PREVALENCE ON LAST TRIMESTER OF PREGNANCY].

INTRODUCTION

recent studies suggest that women with gestational diabetes are more likely to suffer sleep disorders compared to pregnant women without diabetes. The objectives of this study were to analyze the risk factors associated with gestational diabetes and to verify if exist an association between the presence or abscense of gestational diabetes and the quality of the sleep and/or daytime sleepiness.

MATERIAL AND METHODS

case-controls study with a sample of 130 pregnant women, 46 of them with gestational diabetes and 84 controls. Anthropometric parameters such as weight, stature, body mass index (BMI) and abdominal perimeter were evaluated. Socio-demographic variables, including age and family situation were assessed, and a gynecological study was performed, evaluating the number of simple or multiple births, number of miscarriages and gynecological pathology during the past 3 years. The O'Sullivan test was conducted for the diagnosis of gestational diabetes. The quality of sleep and daytime sleepiness were also measured.

RESULTS

46 women were diagnosed of gestational diabetes. There are significant differences (p < 0.001) in BMI scores among women with gestational diabetes and controls, being the highest values in the diabetic group. There is a significant association (p = 0.002) between the existence of family history of type 2 diabetes mellitus and the presence or abscense of gestational diabetes. Women with gestational diabetes present a significant worse quality of sleep (p < 0.001), and values of daytime sleepiness higher than the general population.

CONCLUSIONS

high values of BMI or family history of type 2 diabetes mellitus seems to be factors associated to the risk of suffer gestational diabetes. Women with gestational diabetes have a poorer quality of sleep and a higher degree of daytime sleepiness than the general population, reducing the well-being of the mother and the fetus.
