“…The multinomial model nevertheless has the advantage of being more efficient and hence yielding narrower CIs. 18 A more parsimonious ordinal logistic model was also tested, but the proportional odds assumption that underlies it was not tenable and so the results from the multinomial model were retained. Unadjusted ORs were estimated without controlling for other variables.…”

BackgroundThere is a strong case for early identification of factors predicting life-course-persistent conduct disorder. The authors aimed to identify factors associated with repeated parental reports of preschool conduct problems.MethodNested case–control study of Scottish children who had behavioural data reported by parents at 3, 4 and 5 years.Results79 children had abnormal conduct scores at all three time points (‘persistent conduct problems’) and 434 at one or two points (‘inconsistent conduct problems’). 1557 children never had abnormal scores. Compared with children with no conduct problems, children with reported problems were significantly more likely to have mothers who smoked during pregnancy. They were less likely to be living with both parents and more likely to be in poor general health, to have difficulty being understood, to have a parent who agrees that smacking is sometimes necessary and to be taken to visit other people with children rarely. The results for children with persistent and inconsistent conduct problems were similar, but associations with poverty and maternal smoking were significantly less strong in the inconsistent group.ConclusionThese factors may be valuable in early identification of risk of major social difficulties.

“…19 P-values for trend were computed across categories of duration of use (5-year categories). Given the design of this study, its frequency matched sample of IDC cases based on age, and our exclusion of other histologic subtypes of breast cancer risk, estimates for breast cancer overall could not be calculated.…”

Background The Women’s Health Initiative (WHI) randomized trials found that use of combined estrogen and progestin menopausal hormone therapy (CHT) increases breast cancer risk, but use of unopposed estrogen hormone therapy (EHT) does not. However, several questions regarding the impact of hormone use on risk of different types of breast cancer and what thresholds of use confer elevations in risk remain. Methods We conducted a population-based case-control study among women 55–74 years of age to assess the association between menopausal hormone use and risk of invasive ductal and invasive lobular breast carcinomas. Associations were evaluated using polytomous logistic regression and analyses included 880 ductal cases, 1,027 lobular cases, and 856 controls. Results Current EHT and CHT use were associated with 1.6-fold [95% confidence interval (CI): 1.1–2.2] and 2.3-fold (95% CI: 1.7–3.2) increased risks of lobular breast cancer, respectively, but neither was associated with risk of ductal cancer. Lobular cancer risk was increased after nine years of EHT use, but after only three years of CHT use. Discussion Evidence across more than a dozen studies indicates that lobular carcinoma is the type of breast cancer most strongly influenced by menopausal hormones. Here we characterize what thresholds of duration of use of both EHT and CHT that confer elevations in risk. Impact Despite the rapid decline in hormone therapy use the WHI results were published, study of the hazards associated with these medications remains relevant given the estimated 38 million hormone therapy prescriptions that are still filled in the United States annually.
