    Article - En anglais

    Objective and Method 

    Aggregating across retrospective conort samples, mis integrative review synthesizes the findings of 12 cumulative incidence studies (45 hypotheses) on anorexia nervosa secular trends.


    (1) The female/male anorexia incidence rate ratio was estimated to be 8.20,18.46 versus 2.25 cases per 100,000 per year, p<. 05 ; (2) female teenagers experienced anorexia at a rate fivefold greater than other women, 50.82 versus 10.37 incident cases per 100,000 per year, p<. 001 (3) no secular trend or change in the incidence of anorexia was observed among teenagers, while a near threefold increase was observed over the past 40 years among women in their 20s and 30s, 6.28 (1 950-1 964) versus 17. 70 Ii 980-1 992) cases per 1 00,000 per year, p<. 05 ; and (4) the two cohort characteristics of age, and the age by year interaction accounted for nearly two thirds of the variability among anorexia incidence estimates, R2=614, F (2,27)=21.49, p<. 001.

    After the two factors of age and the Age x Year interaction were accounted for, none of the other study characteristics, including study year (s), were found to be significantly associated with anorexia incidence, that is, a main effect of time was not observed. (...)
