PURPOSE:Descriptive studies have indicated a rising trend in Hodgkin's lymphoma (HL) incidence in young adults, especially females. Increasing evidence has suggested that some risk factors associated with HL may vary by age or gender. Recent studies have reported an increased risk of HL associated with increasing body mass index (BMI), but the results have been inconsistent. The objectives of this study were to examine whether the associations between measures of body size (height, weight, and BMI) and HL risk vary by age and/or gender. METHODS:A population-based case-control study was conducted in Connecticut and Massachusetts. A total of 567 HL cases and 679 controls were recruited in 1997-2000. Unconditional logistic regression was used to calculate odds ratios (ORs) and 95 % confidence intervals (CIs). RESULTS:Among younger women <35 years old, being overweight (25-29.9 kg/m(2)) versus normal weight (18.5-24.9 kg/m(2)) was significantly associated with an increased risk of HL (OR = 2.1, 95 % CI = 1.1-4.0). The risk increased with increasing weight and BMI (p trends <0.01). Among women ≥35 years old, by contrast, higher weight and BMI were associated with a reduced risk of HL (p trends <0.01). Conversely, there was no significant association between BMI and risk of HL in younger or older males. CONCLUSIONS:These findings show that the associations between body size and risk of HL vary by gender and age, and require confirmation in other populations.

目的:描述性研究表明,霍奇金淋巴瘤(HL)的发病率在年轻人中,尤其是女性中呈上升趋势。越来越多的证据表明,与HL相关的某些危险因素可能随年龄或性别而变化。最近的研究报告了与体重指数(BMI)增加相关的HL风险增加,但结果不一致。这项研究的目的是检查身体大小(身高,体重和BMI)与HL风险之间的关系是否随年龄和/或性别而变化。
方法:在康涅狄格州和马萨诸塞州进行了一项基于人群的病例对照研究。在1997-2000年间,共招募了567例HL病例和679例对照。使用无条件逻辑回归来计算比值比(OR)和95%置信区间(CIs)。
结果:<35岁的年轻女性中,超重(25-29.9 kg / m(2))与正常体重(18.5-24.9 kg / m(2))与HL风险增加显着相关(OR = 2.1 ,95%CI = 1.1-4.0)。风险随着体重和BMI的增加而增加(p趋势<0.01)。相比之下,≥35岁的女性中,体重增加和BMI升高与HL风险降低相关(p趋势<0.01)。相反,年轻或老年男性的BMI与HL风险之间没有显着相关性。
结论:这些发现表明,体型与HL风险之间的关联因性别和年龄而异,需要在其他人群中进行确认。
