XXXX and early menarche among peruvian @entity1 .

@entity1 @entity734 @entity458
PURPOSE: @entity734 has been associated with age of menarche in some studies, but not all, and few have assessed the independent associations of @entity458 with early menarche. We examined the association between childhood abuse and early menarche among pregnant @entity1 in Lima, Peru. METHODS: Multinomial logistic regression procedures were used to estimate odds ratios (OR) and 95% confidence intervals (CIs) for early menarche ( <=11  years) in relation to any physical or sexual childhood abuse, physical abuse only, @entity458 , and both physical and @entity458 in a cohort of 1,499 pregnant (first trimester) @entity1 . RESULTS: Approximately 69% of @entity1 reported experiencing physical or @entity458 in childhood. The frequencies of physical abuse only, @entity458 , and both physical and @entity458 were 37.4%, 7.7%, and 24.5%, respectively. Compared with @entity1 who reported no childhood abuse, those who reported any childhood abuse had a 1.38-fold increased odds of early menarche (95% CI, 1.01-1.87). Compared with no abuse, the odds of early menarche was 1.60-fold among @entity1 with childhood @entity458 (OR, 1.60; 95% CI, .93-2.74) and 1.56-fold for those with both physical and @entity458 (OR, 1.56; 95% CI, 1.07-2.25) during childhood. Isolated physical abuse was weakly associated with early menarche (OR, 1.23; 95% CI, .87-1.74). There was no clear evidence of association of childhood abuse with late menarche (>= 15  years). CONCLUSIONS: @entity734 , particularly joint physical and @entity458 , is associated with early menarche. Our findings add to an expanding body of studies documenting the enduring adverse health consequences of childhood abuse.
