Thin body preoccupation and social pressure to be thin (TBPSP) in adolescence are risk factors for the development of full and partial bulimia nervosa and binge eating disorder. This study examined precursors of these potent risk factors.
A prospective study followed 134 children from birth to 11.0 years and their parents. Recruitment began in January 1990 and ended in March 1991. The study was completed in December 2002.
Two moderators identified different groups at risk for the development of TBPSP. A father with high body dissatisfaction characterized the largest group in which TBPSP was elevated for girls who were concerned about and attempted to modify their weight and for children with fathers who had a high drive for thinness. A child at risk for overweight characterized the second smaller group. Parental behaviors such as overcontrol of their child's eating, together with later pressure from parents and peers to be thin, were related to higher levels of TBPSP.
Different pathways lead to the development of eating disorder psychopathology. These results suggest that prevention programs for eating disorders should begin in early childhood, possibly involving parental education and behavior change, and that different prevention programs may be required for different pathways.
青少年期对瘦的过度关注以及追求瘦的社会压力(TBPSP)是完全型和部分型神经性贪食症及暴饮暴食症发展的风险因素。本研究调查了这些强大风险因素的先兆。
一项前瞻性研究跟踪了134名从出生到11.0岁的儿童及其父母。招募工作于1990年1月开始,1991年3月结束。该研究于2002年12月完成。
两位调节变量识别出了不同的TBPSP发展风险组。身体不满程度高的父亲所构成的组规模最大,在该组中,关注并试图改变体重的女孩以及父亲对瘦有强烈追求的孩子的TBPSP水平升高。有超重风险的孩子构成了规模较小的第二组。父母对孩子饮食的过度控制等行为,以及后来父母和同伴追求瘦的压力,都与更高水平的TBPSP相关。
不同的途径会导致饮食失调心理病理学的发展。这些结果表明,饮食失调预防项目应在幼儿期开始,可能涉及家长教育和行为改变,并且不同的途径可能需要不同的预防项目。
