To determine the influence of breastfeeding on overweight and obesity, as determined by body mass index in early adulthood.
Obesity is a contemporary epidemic and linked to increased risk of later cardiovascular disease and type 2 diabetes. The success of long-term treatment is modest. Protective factors, such as potentially, and breastfeeding, are few and very important. There are uncertainties as to whether breastfeeding has a protective effect, especially in adults, or whether it is a reflection of other markers of obesity that are more linked to cardiovascular disease and diabetes risk. Some studies suggest that breastfeeding is protective in later life for cardiovascular disease and atherosclerosis.
Epidemiological analysis of longitudinal data set.
We collected data about breastfeeding duration, body mass index of children at 21 years and confounding variables from an ongoing longitudinal study of a singleton birth cohort of 7223 children in Brisbane. We assessed the duration of breastfeeding at six months and prevalence of overweight and obesity at 21 years by body mass index. Adjustment for potential confounders was by multivariable multinomial logistic regression.
Data were available for 2553 young adults. In neither the unadjusted or adjusted analysis was longer duration of breastfeeding associated with reduction in obesity at 21 years.
Findings of this investigation are consistent with breastfeeding not independently affecting body mass index in young adults.
Breastfeeding has a range of important benefits for infants, mothers and families, although duration of breastfeeding may not play a substantial role in preventing adult onset obesity.
通过身体质量指数（BMI）在成年早期来确定母乳喂养对超重和肥胖的影响。
肥胖是当代的一种流行病，与心血管疾病和 2 型糖尿病风险增加有关。长期治疗的成功率有限。潜在的保护因素，如母乳喂养，很少且非常重要。母乳喂养是否具有保护作用，特别是在成年人中，或者它是否反映了与心血管疾病和糖尿病风险更相关的其他肥胖标志物，存在不确定性。一些研究表明，母乳喂养对心血管疾病和动脉粥样硬化具有保护作用。
对纵向数据集的流行病学分析。
我们从布里斯班一项对 7223 名单胎出生队列的持续纵向研究中收集了有关母乳喂养持续时间、儿童 21 岁时 BMI 以及混杂变量的数据。我们通过 BMI 评估了 6 个月时母乳喂养的持续时间和 21 岁时超重和肥胖的流行率。通过多变量多项逻辑回归对潜在混杂因素进行了调整。
共有 2553 名年轻人的数据可用。在未调整或调整分析中，母乳喂养时间较长与 21 岁时肥胖的减少无关。
这项研究的结果与母乳喂养不能独立影响年轻人的 BMI 一致。
母乳喂养对婴儿、母亲和家庭有一系列重要的益处，尽管母乳喂养的持续时间可能在预防成人肥胖方面没有起到实质性的作用。
