Strategy for recruitment and factors associated with motivation and satisfaction in a randomized trial with 210 healthy volunteers without financial compensation.

BACKGROUND: The aim was to describe a strategy for recruitment of healthy volunteers (HV) to a randomized trial that assessed the efficacy of different telephone techniques to assist HV in performing cardiac massage for vital emergency. Participation in the randomized trial was not financially compensated, however HV were offered emergency first-aid training. We also studied factors associated with HV motivation and satisfaction regarding participation in the trial. METHODS: Strategy for recruitment of 210 HV aged 18 to 60 years was based on: (1) the updated records of all telephone number since January 2000 of HV registered in the Rouen Clinical Investigation Centre HV database, (2) a communication campaign for the general public focussing on posters and media advertisements. Data on the recruitment, socio-demographics, motivation and satisfaction of the 210 HV were collected by anonymous self-administered questionnaire. RESULTS: Of the 210 HV included, 63.3% (n = 133) were recruited from the HV database and 36.7% (n = 77) by the communication campaign. On the one hand, the HV database enabled screening of 1315 HV, 54.8% (n = 721) of whom were reached by phone, 55.2% (n = 398) of these latter accepted to participate in the study and 10.1% of the initial screening (n = 133) were finally included. One the other hand, for the 77 HV not recruited from the HV database, word-of-mouth (56.1%) was the main means of recruitment. The male/female ratio of the 210 HV was 0.5 and mean age 43.5 years (Standard Deviation = 12.4). The main motivations given for participating in the trial were to support research (87.6%) and receive emergency first-aid training (85.7%). Overall satisfaction with the welcome process was significantly higher for older HV (46-60 years) (adjusted odds ratio (AOR): 3.44; 95% confidence interval (95% CI): 1.48-7.99), and for HV in management jobs (AOR: 4.26; 95% CI: 1.22-14.87). Satisfaction with protocol management was higher for women (AOR: 2.33; 95% CI: 1.18-4.60) and for older HV (46-60 years) (AOR: 4.76; 95% CI: 1.97-11.52). CONCLUSIONS: Recruitment of non-compensated HV required broad screening with a primary HV database alongside word-of-mouth communication which seemed more efficient than media advertising. To enhance HV recruitment to randomized trials without financial compensation it seems crucial to provide them not only with a direct interest but also to ensure their satisfaction.

Imagem corporal, atividade física e estado nutricional em adolescentes no sul do Brasil / Body image, physical activity and nutritional status in adolescents in southern Brazil

Este estudo objetivou descrever a frequência da prática de exercícios e o tempo gasto em atividades sedentárias, avaliar o índice de massa corporal (IMC) e correlacioná-lo com a percepção da imagem corporal por meio do Body Shape Questionnaire (BSQ). Foram coletados dados de 336 escolares de Gravataí/RS. Foi encontrada uma correlação significativa entre BSQ e IMC (r= 0,39 e p<0,01). Nas adolescentes, o IMC foi de 20.43±3.56 kg/m² e o BSQ de 82.30±31.37. Nos adolescentes, o IMC foi 20.31±3.82 kg/m² e o BSQ de 53.10±19.25. Houve maior preocupação das adolescentes em relação à imagem corporal e menor frequência e tempo de prática de atividade física quando comparado aos adolescentes. Mais de 80% dos estudantes realiza deslocamento ativo para a escola. Os resultados sugerem que as adolescentes são mais sedentárias e preocupadas com a imagem corporal do que os adolescentes.(AU)

This study aimed to describe the frequency of exercise and time spent in sedentary activities, evaluate the body mass index (BMI) and correlate it with the perception of body image by Body Shape Questionnaire (BSQ). Data were collected from 336 students from Gravataí/RS. A significant correlation between BSQ and BMI (r = 0.39 P<0.01) was found. Teenage girls' BMI was 20.43±3.56 kg/m² and the BSQ result was 82.30±31.37. BMI of teenage boys was 20.31±3.82 kg/m² and the BSQ was 53.10±19.25. There was a greater concern for adolescent girls regarding body image and lower frequency and time physical activity compared to adolescent boys. More than 80% of the sample performs active commuting to school. The results suggest that teenage girls are more sedentary and concerned with body image than teenage boys.(AU)
