The relations between life changes, locus of control and changes in the parameters of the metabolic syndrome were examined. A three-year follow-up study of 671 randomly selected, healthy adolescents and young adults was used. Somatic parameters measured both at the baseline and the follow-up were serum insulin, serum HDL chol, serum triglyceride, SBP and BMI. Locus of control was measured with the Nowicki-Strickland locus of control scale and subjects were asked about life changes that they had faced during the follow-up period. Results showed that, in women, there were significant main effects for life changes in predicting (high) somatic risk level, whereas, in men, an opposite association was found. In addition, locus of control had a moderating effect on the life change-metabolic parameters relation, i.e. most of the life changes predicted a lower level of somatic risk in subjects with an external rather than internal locus of control. Results question the universal applicability of beneficial health effects of internal locus of control. It was suggested that accumulation of life changes might contribute, in interaction with locus of control, to the early development of the metabolic syndrome.
研究了生活变化、控制点与代谢综合征参数变化之间的关系。采用了对671名随机选取的健康青少年和青年成年人进行的为期三年的随访研究。在基线和随访时测量的身体参数包括血清胰岛素、血清高密度脂蛋白胆固醇、血清甘油三酯、收缩压和体重指数。使用诺维茨基 - 斯特里克兰控制点量表测量控制点，并询问受试者在随访期间所面临的生活变化。结果表明，在女性中，生活变化在预测（高）身体风险水平方面有显著的主效应，而在男性中则发现了相反的关联。此外，控制点对生活变化与代谢参数之间的关系有调节作用，即大多数生活变化在具有外部而非内部控制点的受试者中预测较低水平的身体风险。结果质疑了内部控制点对健康有益影响的普遍适用性。有人提出，生活变化的积累可能与控制点相互作用，促成代谢综合征的早期发展。
