Performance of parental history for the targeted screening of hypertension in children.

OBJECTIVES: Several guidelines recommend universal screening for hypertension in childhood and adolescence. Targeted screening to children with parental history of hypertension could be a more efficient strategy than universal screening. Therefore, we assessed the association between parental history of hypertension and hypertension in children, and estimated the sensitivity, specificity, negative, and positive predictive values of parental history of hypertension for hypertension in children. METHODS: The present study was a school-based cross-sectional study including 5207 children aged 10-14 years from all public 6th grade classes in the Canton of Vaud, Switzerland. Children had hypertension if they had sustained elevated blood pressure over three separate visits. RESULTS: In children, the prevalence of hypertension was 2.2%. Some 8.5% of mothers and 12.9% of fathers reported to be hypertensive. Maternal history of hypertension (odds ratio 2.0, 95% confidence interval 1.2-3.3) and paternal history of hypertension (odds ratio 2.2, 95% confidence interval 1.4-3.6) were independent risk factors for hypertension in children. Nevertheless, the sensitivity of parental history of hypertension for the identification of hypertension in children was low (from 4% for both parents' positive history up to 41% for at least one parent's positive history). Positive predictive values were also low (between 4 and 5%). CONCLUSION: Children with hypertensive parents were at higher risk of hypertension. Nevertheless, parental history of hypertension helped only marginally to identify hypertension in offspring. Targeting screening only toward children with a parental history of hypertension may not be a substantially better strategy to identify hypertension in children compared with universal screening.

Assessing an Adolescent's Capacity for Autonomous Decision-Making in Clinical Care.

The purpose of this article is to provide policy guidance on how to assess the capacity of minor adolescents for autonomous decision-making without a third party authorization, in the field of clinical care. In June 2014, a two-day meeting gathered 20 professionals from all continents, working in the field of adolescent medicine, neurosciences, developmental and clinical psychology, sociology, ethics, and law. Formal presentations and discussions were based on a literature search and the participants' experience. The assessment of adolescent decision-making capacity includes the following: (1) a review of the legal context consistent with the principles of the Convention on the Rights of the Child; (2) an empathetic relationship between the adolescent and the health care professional/team; (3) the respect of the adolescent's developmental stage and capacities; (4) the inclusion, if relevant, of relatives, peers, teachers, or social and mental health providers with the adolescent's consent; (5) the control of coercion and other social forces that influence decision-making; and (6) a deliberative stepwise appraisal of the adolescent's decision-making process. This stepwise approach, already used among adults with psychiatric disorders, includes understanding the different facets of the given situation, reasoning on the involved issues, appreciating the outcomes linked with the decision(s), and expressing a choice. Contextual and psychosocial factors play pivotal roles in the assessment of adolescents' decision-making capacity. The evaluation must be guided by a well-established procedure, and health professionals should be trained accordingly. These proposals are the first to have been developed by a multicultural, multidisciplinary expert panel.
