Longitudinal research into health and growth of adolescents. The study up till now contains data from measurements in 1976-1979, 1985, 1991, 1993, 1996 and 1997. The longitudinal group consisted at the start of 307 pupils (age cohorts 1962, 1963 and 1964) from one school for secondary education in Amsterdam, of which 233 completed the first four years of the study. At the first four years a control group of 292 pupils from a comparable school near Amsterdam were studied. In 1985 200 pupils from the longitudinal group were remeasured, their number dropping slowly afterwards. In 1996 control-group subjects were invited for measurement again and this will continue in future. Measurements fell broadly into five categories: 1. Physical measurements of body build, body growth and body composition 2. Physiological measurements of functional and performance characteristics 3. Psychological measurements of personality traits 4. Lifestyle measurements, concerning dietary habits, habitual physical activity, psychosocial behaviour and stress 5. Health measurements, concerning both physical and mental aspects. ad 1. Physical measurements: height / weight / bone diameter / skinfold thickness / circumference / fat mass / skeletal age / curvature of thoracolumbar spine / bone mineral content. ad 2. Physiological measurements: motor performance fitness test / strength / speed / flexibility / aerobic endurance / maximal aerobic power and maximal isokinetic muscle power / treadmill running / cardiovascular measurement / ventilation, respiration, oxygen uptake and carbon dioxide production / maximal isokinetic torque / blood pressure / lung function / analysis of blood (cholesterol) , urine (catecholamines, drug use) and saliva (immoglobulin A). ad 3. Psychological measurements: Dutch Personality Inventory (inadequacy / social inadequacy / rigidity / self-sufficience / dominance) / Achievement motivation test (achievement motivation / debilitating anxiety / facilitating anxiety / social desirability) / sociometric status. ad 4. Lifestyle: Habitual food intake / parents dietary questionnaire / smoking / alcohol intake / habitual physical activity / sports injuries / psychosocial behaviour and stress / coronary-prone behaviour pattern / coping style / life events / daily hassles. ad 5. Health measurements: mental health: mild health complaints, sleep-wake problems, vital exhaustion, inadequacy / physical health: back pain, health questionnaire. The study contains at present some 185 files with varying numbers of cases and variables. Detailed information at the file level is available on request.
