Use of genetic variation to separate the effects of early and later life adiposity on disease risk: mendelian randomisation study.

ABSTRACT:

Objective

To evaluate whether body size in early life has an independent effect on risk of disease in later life or whether its influence is mediated by body size in adulthood.

Design

Two sample univariable and multivariable mendelian randomisation.

Setting

The UK Biobank prospective cohort study and four large scale genome-wide association studies (GWAS) consortiums.

Participants

453 169 participants enrolled in UK Biobank and a combined total of more than 700 000 people from different GWAS consortiums.

Exposures

Measured body mass index during adulthood (mean age 56.5) and self-reported perceived body size at age 10.

Main outcome measures

Coronary artery disease, type 2 diabetes, breast cancer, and prostate cancer.

Results

Having a larger
