Diabetes in pregnant Mexican-American women is a serious and expensive
health problem. At the University of California, San Diego Medical Center,
44% of pregnant women are Mexican American. In the Diabetes in Pregnancy
Clinic, only 7% of women with insulin-dependent diabetes are in this ethnic
group compared with 66% of non-insulin-dependent diabetic patients and 51%
of those with gestational diabetes mellitus (GDM). GDM is the most common
complication of pregnancy in Mexican Americans with a prevalence
approximately three times higher than that of whites (4.5 vs. 1.5%).
Mexican-American obese GDM subjects had more frequent cesarean sections and
were more likely to have complications of premature rupture of membranes
and preterm labor (NS). Polycythemia and sepsis also occurred more often in
their infants. Anthropometric measurements in infants of both lean and
obese GDM subjects differed from those of infants of mothers without GDM.
Infants of lean mothers with GDM were heavier and longer than those of lean
mothers without GDM. In addition, they had increased waist-hip ratio and
triceps and subscapular skin folds. Infants of obese mothers with GDM were
heavier than those of lean mothers with GDM. Moreover, they were longer (P
less than 0.04); had a higher body mass index (P less than 0.04); and
larger waist and hip circumferences (P less than 0.03) and buccal (P less
than 0.01), subscapular (P less than 0.01), and sum of skin-fold
measurements (P less than 0.03). Our observations indicate that pregnant
diabetic Mexican-American women have predominantly GDM and
non-insulin-dependent diabetes. They represent a major public health
problem because of increased maternal and neonatal morbidity.
