Pregnant women with gestational diabetes in Chennai had lower serum chromium than matched pregnant controls. Differences were not significant when groups were split by parity.
Key numbers
- Serum chromium: gestational diabetes 1.59 ± 0.02 ng/mL (range 0.16 to 4.0), n = 30; controls 4.58 ± 0.62 ng/mL (range 0.82 to 5.33), n = 60; P < 0.001 (Table 1, p. S71).
Methods (brief)
Case-control comparison; fasting serum chromium by inductively coupled plasma emission spectrometry.
Evidence fitness
Supports an observed association between lower serum chromium and gestational diabetes in one Indian city. It does not establish causation or benefit from supplementation.
Limitations
Small sample; dispersion statistic not identified (the narrow value for cases, against a wide range, suggests a standard error); no detection limit or reference material reported.
