Adolescence is a time of rapid gain in bone density which may be influenced by calcium intake. This study assessed whether dieting concerns, known to be prevalent in adolescent girls, were associated with the calcium intake of adolescents of varying ethnicity.
Students (n = 856) completed an instrument which assessed current weight, desired weight, height, age, ethnicity, calcium intake using a food frequency questionnaire, dieting concerns using the Eating Attitudes Test dieting subscale (DS), taste enjoyment of dairy products, and type of milk consumed.
Among 782 students with useable responses, most girls (69.1%) wanted to lose weight and most boys (54.2%) wanted to gain weight. Asian girls had lower body mass index (BMI) than Caucasians (19.3 +/- 2.1 vs 20.8 +/- 2.6 kg/m2, p < 0.05), but desired BMI did not vary by ethnicity in either girls or boys. Asian girls also had lower DS scores than Caucasians, but the difference was not significant with current BMI as a covariate. Girls' DS scores were higher than those of boys (6.3 +/- 6.5 vs 2.3 +/- 3.2, p < 0.001), and estimated calcium intakes were lower (815 +/- 528 vs 1149 +/- 701 mg/day, p < 0.001); however, DS scores were not associated with calcium intake for either sex. Especially among girls, dieting and body size concerns were associated with taste enjoyment of certain dairy products, and with the type, but not the amount, of milk consumed. Girls using skim milk had higher DS scores than those using low-fat or whole milk.
In this non-clinical sample, greater concern about dieting and body size did not directly compromise calcium intake but was associated with the type of milk used.
青春期是骨密度快速增加的时期，这可能受钙摄入量的影响。本研究评估了在青春期女孩中普遍存在的节食担忧是否与不同种族青少年的钙摄入量相关。
学生（n = 856）完成了一份问卷，该问卷使用食物频率问卷评估当前体重、期望体重、身高、年龄、种族、钙摄入量，使用饮食态度测试节食分量表（DS）评估节食担忧，评估对乳制品的口味喜好以及所饮用牛奶的类型。
在782名有可用回复的学生中，大多数女孩（69.1%）想减肥，大多数男孩（54.2%）想增重。亚洲女孩的体重指数（BMI）低于白种人（19.3±2.1 vs 20.8±2.6 kg/m²，p < 0.05），但无论女孩还是男孩，期望的BMI并不因种族而异。亚洲女孩的DS得分也低于白种人，但以当前BMI作为协变量时，差异不显著。女孩的DS得分高于男孩（6.3±6.5 vs 2.3±3.2，p < 0.001），估计的钙摄入量较低（815±528 vs 1149±701毫克/天，p < 0.001）；然而，DS得分与任何性别的钙摄入量均无关联。特别是在女孩中，节食和对体型的担忧与某些乳制品的口味喜好以及所饮用牛奶的类型有关，但与饮用牛奶的量无关。饮用脱脂牛奶的女孩比饮用低脂或全脂牛奶的女孩DS得分更高。
在这个非临床样本中，对节食和体型的更大担忧并未直接影响钙摄入量，但与所饮用牛奶的类型有关。
