OBJECTIVES To identify groups of children with distinct developmental trajectories of body mass index (BMI), calculated as weight in kilograms divided by height in meters squared, between the ages of 5 months and 8 years and identify early-life risk factors that distinguish children in an atypically elevated BMI trajectory group. DESIGN Prospective cohort(More)
The present study assesses the prevalence of subclinical eating disorders and examines their comorbidity with mood and anxiety disorders in a sample of adolescent girls. A DSM-III-R computerized self-reported interview was administered to 833 adolescent girls (mean age=15.7±0.5 years) from a population sample to assess the prevalence of subclinical eating(More)
OBJECTIVES During the last decade, vasoactive intracavernosal pharmacotherapy (VIP) has been used extensively for the treatment of erectile dysfunction. However, there is concern about high discontinuation rates and the possibility of long-term complications. Because of few long-term studies on VIP, we investigated efficacy, side effects, satisfaction(More)

Kindergarten boys and girls attending French-speaking(More)
The first step in searching the causes of a disorder is to provide a definition of the phenomenon under study. This may seem obvious, yet different forms of measurement have different properties and entail strengths and limitations which are not always acknowledged. Data on children’s mental health problems come either from clinical records or from(More)
BACKGROUND Overweight is associated with depression and anxiety among adults. It is unclear whether this association begins in childhood. Overweight among children is associated with a higher risk of peer victimization, and may mediate an association between overweight and internalizing symptoms. No study has tested this hypothesis in a longitudinal(More)
Food insecurity has been found to be related to anxiety and depression; however, the association with other psychiatric disorders, particularly among young adults, is not well known. We examined whether food insecurity is independently associated with four common mental health problems among a community sample of young adults in France. Data are from the(More)
Background : Adolescent cannabis use has been reported to predict later educational attainment; however, results of past studies may be confounded by inappropriate control for factors that make some youths more likely to use cannabis precociously than others. We aimed to test the possibility of a causal relationship between early cannabis initiation and(More)
BACKGROUND Research is needed to identify early life risk factors associated with different developmental paths leading to overweight by adolescence. OBJECTIVES To model heterogeneity in overweight development during middle childhood and identify factors associated with differing overweight trajectories. METHODS Data was drawn from the Quebec(More)
of social inequalities observed varies both with measures of socioeconomic position and psychopathology. Measures tapping into poverty, such as food insecurity, or those that take into account young people’s perceptions appear most strongly associated with mental health. Similarly, socioeconomic inequalities appear most consistent with regard to(More)
