Background

Bisphenol A (BPA) exposure has been associated with diabetes and related metabolic disorders, such as obesity, but studies of the association of urinary BPA concentrations with central obesity risk are limited. The aim of this study was to prospectively investigate the association between urinary BPA and incident central obesity in a Chinese population aged ≥40 years.

Methods

The study followed 888 participants from Shanghai, China, who did not have central obesity at baseline (in 2009) for 4 years. Concentrations of BPA were measured in baseline morning spot urine samples. Central obesity was defined as waist circumference ≥90 cm in men and ≥80 cm in women.

Results

During a mean follow-up of 4 years, 124 (14.0%) participants developed central obesity. Each 1-unit increase in log [BPA] was positively associated with a 2.30-fold risk of incident central obesity (95% confidence interval [CI] 1.39–3.78; P  < 0.001) after adjustment for confounders. Compared with the lowest tertile of urinary BPA concentration, Tertiles 2 and 3 were associated with a higher risk of incident central obesity (odds ratios 1.73 [95% CI 1.04–2.88] and 1.81 [95% CI 1.08–3.05], respectively). Stratified analysis showed significant associations of BPA with incident central obesity in women and individuals <60 years of age, with normal weight, non-smokers, non-drinkers, or non-hypertensives.

Conclusions

The results indicate that higher urinary BPA concentrations may be associated with a greater risk of incident central obesity in Chinese adults. The study emphasizes the effects of BPA exposure on metabolic risk from a public health perspective.

摘要

背景

既往研究显示,  双酚A(Bisphenol A,  BPA)暴露与糖尿病和包括肥胖等在内的代谢异常疾病相关。但是关于尿双酚A浓度与中心性肥胖发生风险的相关性研究十分有限。本研究旨在中国40岁及以上社区人群中前瞻性探究尿双酚A浓度与中心性肥胖发病风险的相关性。

方法

本研究对上海市888名基线调查时(2009年)的非中心性肥胖受试者进行了平均时间为4年的随访调查,  包括问卷调查、体格检查、血尿标本生化指标检测等。检测基线清晨点尿样本中双酚A的浓度,  以男性腰围≥ 90cm和女性腰围≥ 80cm作为中心性肥胖的诊断标准。

结果

在平均时间为4年的随访期间,  124人(14.0%)新发生了中心性肥胖。校正年龄、性别、尿肌酐浓度、吸烟饮酒状态、受教育水平和糖尿病等因素后,  对数转换后的双酚A浓度每增加1个单位,  中心性肥胖发生风险增加2.30倍(95% CI:1.39-3.78;P < 0.001)。将研究对象以双酚A浓度三分位切点分为三组,  与双酚A浓度最低分位组相比,  双酚A浓度较高及最高分位组的受试者发生中心性肥胖的风险更高[OR(95% CI)分别为:1.73(1.04-2.88)及1.81(1.08-3.05)]。分层分析显示,  在女性、年龄< 60岁、体重正常、非吸烟者、非饮酒者及非高血压者中,  尿双酚A浓度与新发中心性肥胖风险显著相关。

结论

研究结果表明,  中国成年人的高尿双酚A浓度与高中心性肥胖发生风险相关。本研究从公共卫生学角度强调了双酚A暴露对代谢相关风险的影响。
