Biochemical analyses of the myometrium at term of the normal weight group (18.5 < BMI < 25 kg m⁻²) and obese group (BMI ≥ 30 kg m⁻²)

	Normal wt	Obese
	(n = 19)	(n = 17)	P
Triglycerides (mm)	1.56 ± 0.20	2.39 ± 0.26*	0.024
Protein (mg g−1 wet wt)	139.4 ± 5.6	109.2 ± 7.2*	0.002
CS activity (U g−1 wet wt)	29.6 ± 1.4	24.8 ± 1.0*	0.008
CS activity (U mg−1 protein)	0.22 ± 0.01	0.24 ± 0.02	0.363
Complex I (protein, AU)	2.06 ± 0.38	2.33 ± 0.65	0.825
Complex II (protein, AU)	1.55 ± 0.21	2.25 ± 0.39	0.589
Complex III (protein, AU)	1.09 ± 0.12	1.06 ± 0.18	0.659
Complex IV (protein, AU)	1.90 ± 0.26	2.36 ± 0.45	0.425
Complex V (protein, AU)	0.99 ± 0.07	1.04 ± 0.10	0.653

Triglycerides, protein by wet weight, CS activity expressed by wet weight or protein and complex I, II, III, IV and V of the respiratory chain in the myometrium in women at term grouped by BMI. CS, citrate synthase. Results are given as mean ± SEM. Data were log‐transformed prior to analysis and significance of difference between groups was evaluated by Student's t test; ^*significant difference between groups.
