PURPOSE: To evaluate the methodological and statistical design evolution of the publications in the Brazilian Journal of Gynecology and Obstetrics (RBGO) from resolution 196/96. METHODS: A review of 133 articles published in 1999 (65) and 2009 (68) was performed by two independent reviewers with training in clinical epidemiology and methodology of scientific research. We included all original clinical articles, case and series reports and excluded editorials, letters to the editor, systematic reviews, experimental studies, opinion articles, besides abstracts of theses and dissertations. Characteristics related to the methodological quality of the studies were analyzed in each article using a checklist that evaluated two criteria: methodological aspects and statistical procedures. We used descriptive statistics and the χ2 test for comparison of the two years. RESULTS: There was a difference between 1999 and 2009 regarding the study and statistical design, with more accuracy in the procedures and the use of more robust tests between 1999 and 2009. CONCLUSIONS: In RBGO, we observed an evolution in the methods of published articles and a more in-depth use of the statistical analyses, with more sophisticated tests such as regression and multilevel analyses, which are essential techniques for the knowledge and planning of health interventions, leading to fewer interpretation errors.

OBJECTIVE: to correlate complaints of stress urinary incontinence and the results of a one-hour pad test in pre- and postmenopausal women. METHODS: cross-sectional study conducted on 60 postmenopausal volunteers divided into two groups: one consisting of 34 women with involuntary loss of urine due to stress incontinence and the other consisting of 26 women without involuntary loss of urine. A control group of 15 premenopausal women with normal menstrual cycles and no urinary complaints was also used. All women underwent clinical and laboratory analysis as well as the one-hour pad test. Patients were considered to be incontinent when sanitary pad weight post-test was more than 1 g. Data were submitted to descriptive statistics, parametric ANOVA, post-hoc Tukey test and Pearson's correlation. RESULTS: all postmenopausal women presented with stress urinary incontinence during the pad test, both those with urinary loss (4 g) and with no previous loss (3.5 g). A strong correlation was observed between urinary loss and time since menopause (r=0.8; p<0.01) and body mass index (r=0.7; p=0.01). Premenopausal women were continent during the pad test (0.4 g). CONCLUSIONS: the results of the one-hour pad test showed that all postmenopausal women exhibited stress urinary incontinence, including those without urine loss on effort. Urine loss was correlated with time since menopause and body mass index.
