Abstract

Objective

The objective of this study was to investigate whether the associations between BMI categories and the age-specific prevalence of health conditions common in young women differed across generations.

Methods

Data were from the Australian Longitudinal Study on Women's Health for participants born between 1973 and 1978 or 1989 and 1995 and recruited in 1996 and 2013, respectively. Women were included if they reported their weight and height at waves conducted when they were aged 18 to 23, 22 to 27, and 25 to 30 years. Outcomes were self-rated health, the prevalence of common conditions, menstrual symptoms, and pregnancy complications. Odds ratios (ORs) were estimated using logistic regression models with generalized estimating equations to account for repeated measures.

Results

For fair or poor self-rated health, the ORs were higher for women in the underweight range (OR 1.51, 95% CI: 1.30–1.74) or the overweight range (OR 1.47, 95% CI: 1.34–1.60), were highest for women with obesity (OR 3.04, 95% CI: 2.76–3.35) compared with women with normal weight, and were higher for the more recent cohort (OR 1.50, 95% CI: 1.38–1.63). This same pattern was apparent for all outcomes.

Conclusions

The health impacts of increasing BMI are not lessened in more recent generations. This evidence can be used to promote the benefits of normal BMI for young women.

年轻女性健康状况与BMI类别之间的代际差异

目的：本研究的目的是调查BMI类别与年轻女性常见健康状况的年龄特异性患病率之间的关联是否在几代人之间存在差异。方法：数据来自澳大利亚妇女健康纵向研究，参与者分别出生于1973年至1978年或1989年至1995年，分别于1996年和2013年招募。如果女性在18岁至23岁、22岁至27岁、25岁至30岁时报告了自己的体重和身高，她们就会被纳入研究范围。结果是自评健康、常见疾病的患病率、月经症状和妊娠并发症。比值比（ORs）使用逻辑回归模型和广义估计方程来估计重复测量。结果：对于一般或较差的自评健康，体重过轻的女性（or 1.51, 95% CI: 1.30-1.74）或超重的女性（or 1.47, 95% CI: 1.34-1.60）的or较高，肥胖女性（or 3.04, 95% CI: 2.76-3.35）与体重正常的女性相比，or较高（or 1.50, 95% CI: 1.38-1.63）。同样的模式在所有结果中都很明显。结论：BMI增加对健康的影响在最近几代人中并没有减少。这一证据可以用来促进年轻女性正常BMI的益处。
