The purpose of this paper is to report our experiences with recruiting overweight and obese 13-16 year olds for the Loozit weight management randomized control trial (RCT) and to identify effective recruitment avenues. Methods: The Loozit RCT is a two-arm lifestyle intervention that aims to evaluate the effect of additional therapeutic contact as an adjunct to the Loozit group program (1). The two year Loozit program consists of seven initial adolescent and parent weekly group sessions, followed by a booster session held once a school term for adolescents only. In addition, adolescents in one arm of the study receive additional therapeutic contact in the form of telephone coaching, short messaging service and/or emails. Overweight to moderately obese adolescents aged 13 to 16 years, able to attend the initial weekly group sessions with a parent, were recruited to the Loozit RCT during a period of three years. Numerous recruitment avenues were used including media, schools, community and health professional focused strategies. Results: Out of 474 enquiries received, 32% resulted in an enrolment to the Loozit RCT (151 participants). The three most successful recruitment avenues were media-based strategies (39% of total enquiries and 35% of total enrolments), promotion through schools (28.7% of enquiries and 30.8% of total enrolments) and promotion through health professionals (21.3% of enquiries and 22% of total enrolments). When broken down into individual recruitment strategies, school newsletters showed the highest enrolment rate (9%) followed by local (7%) and city newspapers (5%). Nearly all enquiries from other individual recruitment avenues resulted in less than 5% of total enrolments. School newsletters and newspapers were the most effective recruitment strategies. However, both were significantly demanding in terms of research assistant time. The two most common reasons for ineligibility to participate in the RCT were adolescents being too young (21%) and parents consenting but adolescents refusing to participate (17%). Conclusions: Identification of successful and cost effective recruitment strategies that improve recruitment rates is of crucial importance to community-based health interventions targeted at adolescents. Recruitment of adolescents almost invariably involves parents and the successful recruitment avenues were those which were accessible to parents. The factors which influence adolescents' provision of consent are both complex and difficult to determine.

MCI and AD. In C4-F4, significant differences between AD and HC (p¼0.009) as well as between MCI and HC (p¼0.001) could be shown for P1, but no difference between the two groups of patients. As expected no potentials occurred on the left side of the head. The amplitudes of the VSEP are dispersed with no systematic link to the diagnoses of cognitive decline. Conclusions: VSEP is able to discriminate between cognitively declined patients and healthy controls with regard to the latencies of the potentials. The difference between MCI and AD reached no statistical significance, so further studies are necessary on the (diagnostic) specificity of the findings. The amplitudes of the potential have no diagnostic power.
