To examine health and psychosocial correlates of persistent thinness in black and white young adult women.
1,830 females (n = 988 black, n = 842 white) who participated in the National Heart, Lung, and Blood Institute Growth and Health Study were asked to indicate their current body size from a series of nine pictograms (1, emaciated to 9, obese). Persistent thinness was defined as having at least seven non-missing measurement points between ages 9 to 18 with a body size rating of <4 at all points. Generalized linear models were used to examine whether persistently thin women differed from comparison women on cardiovascular disease risk factors measured at age 18.5 and psychosocial variables measured at age 21.5. Prospective associations between psychological measures in childhood and persistent thinness through the course of adolescence were also examined.
In the sample, 145 women (7.9%) met criteria for persistent thinness and 1,685 women (92.1%) were classified as not persistently thin. Persistently thin women had a later age of menarche, fewer weight concerns, and healthier eating attitudes, were less likely to have had a child, came from higher socioeconomic backgrounds, and had significantly lower blood pressure and higher high-density lipoprotein-cholesterol than comparison women. Differences were not found on measures of depression or health services use. Girls with higher self-esteem in childhood were more likely to remain persistently thin throughout adolescence.
Persistently thin women seem to be healthier on several indicators relative to comparison women, and race did not moderate these differences.
研究黑人和白人年轻成年女性持续消瘦与健康及社会心理因素的相关性。
参与美国国立心肺血液研究所生长与健康研究的1830名女性（988名黑人，842名白人）被要求从九个象形图（1，极度消瘦至9，肥胖）中指出自己当前的体型。持续消瘦定义为在9至18岁之间至少有七个无缺失的测量点，且所有点的体型评级均<4。使用广义线性模型来检验持续消瘦的女性与对照组女性在18.5岁时测量的心血管疾病危险因素和21.5岁时测量的社会心理变量方面是否存在差异。还研究了儿童期心理测量指标与青春期持续消瘦之间的前瞻性关联。
在样本中，145名女性（7.9%）符合持续消瘦标准，1685名女性（92.1%）被归类为非持续消瘦。持续消瘦的女性初潮年龄较晚，对体重的担忧较少，饮食态度更健康，生育孩子的可能性较小，来自社会经济背景较高的家庭，并且与对照组女性相比，血压显著较低，高密度脂蛋白胆固醇较高。在抑郁或医疗服务使用方面未发现差异。童年时期自尊水平较高的女孩在整个青春期更有可能持续消瘦。
相对于对照组女性，持续消瘦的女性在几个指标上似乎更健康，种族并未调节这些差异。
