METHODS We assessed the prevalence of ADHD among a cohort of early school age children in the Jewish and Arab populations using DSM-IV criteria and evaluated the difference between teachers' and parental assessme...

BACKGROUND Cumulative exposure to ultraviolet radiation (UV) is a risk factor for development of skin cancer. We estimated changes in knowledge, attitudes, and behaviors among Nevada school-age children following implementation of a program to decrease UV exposure. COMMUNITY CONTEXT The Nevada Cancer Coalition's Sun Smart Schools pilot program was implemented in 7 Nevada schools during the 20...

The eight subquestions included the effects of age on symptoms and outcome, normal and prolonged duration, the role of computerised neuropsychological tests (CNTs), the role of rest, and strategies for return to school and return to sport (RTSp).

BACKGROUND The scaling of malaria control to achieve universal coverage requires a better understanding of the population sub-groups that are least protected and provide barriers to interrupted transmission. Here we examine the age pattern of use of insecticide treated nets (ITNs) in Africa in relation to biological vulnerabilities and the implications for future prospects for universal coverag...

We report the results of experiments on economic decisions with two populations, one of healthy elderly individuals (average age 82) and one of younger students (average age 20). We examine confidence, decisions under uncertainty, differences between willingness to pay and willingness to accept and the theory of mind (strategic thinking). Our findings indicate that the older adults’ decision be...

BACKGROUND To explore three school based transitions and their impact on positive self-reported-health (SRH), pre-school to elementary school (6-10 y), elementary school to junior high school (10-13 y), and junior high school to upper secondary school/high school (13-16 y), in a long-term longitudinal population based study. METHODS The study followed three cohorts through one school transiti...

BACKGROUND Body weight is highly associated with overall health status. Being severely thin or obese may impose the risk of many health problems. Early detection of body mass index (BMI) status may help to reduce the associated comorbidities. Although many studies in the literature have investigated the BMI of school adolescents in Malaysia, the data on status of body weight among school adoles...

Older children outperform younger children in a school-entry cohort well into their school careers. The existing literature has provided little insight into the causes of this phenomenon, leaving open the possibility that school-entry age is zero-sum game, where relatively young students lose what relatively old students gain. In this paper, we estimate the effects of relative age using data fr...
