Table 3.

Association between lipid-adjusted organochlorine gestational serum concentrations (ng/g lipid) and early menarche (logged organochlorine concentration).

Organochlorine Unadjusted OR (95% CI)a, e Adjusted OR (95% CI)a, e Adjusted p value
HCB 1.06 (0.67–1.68) 0.93 (0.58–1.50)b 0.77
β-HCH 0.91 (0.64–1.29) 0.85 (0.59–1.22)b 0.37
p,p′-DDE 0.91 (0.70–1.19) 0.50c
p,p′-DDT 1.06 (0.72–1.54) 0.97 (0.65–1.42)d 0.84
a

Odds of early menarche for a unit increase of logged organochlorine pesticide concentration.

b

Adjusted for mother’s age at menarche.

c

Unadjusted p value. No potential confounders identified.

d

Adjusted for mother’s prenatal BMI.

e

Number of cases, number of controls used in both unadjusted and adjusted models: HCB (184, 188); β-HCH (186, 188); PP′-DDE (210, 218); PP′-DDT (183, 179).
