      abstract     = {In addition to the established association between general
                      obesity and breast cancer risk, central obesity and
                      circulating fasting insulin and glucose have been linked to
                      the development of this common malignancy. Findings from
                      previous studies, however, have been inconsistent, and the
                      nature of the associations is unclear.We conducted Mendelian
                      randomization analyses to evaluate the association of breast
                      cancer risk, using genetic instruments, with fasting
                      insulin, fasting glucose, 2-h glucose, body mass index (BMI)
                      and BMI-adjusted waist-hip-ratio (WHRadj BMI). We first
                      confirmed the association of these instruments with type 2
                      diabetes risk in a large diabetes genome-wide association
                      study consortium. We then investigated their associations
                      with breast cancer risk using individual-level data obtained
                      from 98 842 cases and 83 464 controls of European descent
                      in the Breast Cancer Association Consortium.All sets of
                      instruments were associated with risk of type 2 diabetes.
                      Associations with breast cancer risk were found for
                      genetically predicted fasting insulin [odds ratio (OR) =
                      1.71 per standard deviation (SD) increase, $95\%$ confidence
                      interval (CI) = 1.26-2.31, p  =  5.09  ×
                       10-4], 2-h glucose (OR = 1.80 per SD increase, $95\%$
                      CI = 1.3 0-2.49, p  =  4.02  ×  10-4), BMI
                      (OR = 0.70 per 5-unit increase, $95\%$
                      CI = 0.65-0.76, p  =  5.05  ×  10-19) and
                      WHRadj BMI (OR = 0.85, $95\%$ CI = 0.79-0.91, p  =
                       9.22  ×  10-6). Stratified analyses showed that
                      genetically predicted fasting insulin was more closely
                      related to risk of estrogen-receptor [ER]-positive cancer,
                      whereas the associations with instruments of 2-h glucose,
                      BMI and WHRadj BMI were consistent regardless of age,
                      menopausal status, estrogen receptor status and family
                      history of breast cancer.We confirmed the previously
                      reported inverse association of genetically predicted BMI
                      with breast cancer risk, and showed a positive association
                      of genetically predicted fasting insulin and 2-h glucose and
                      an inverse association of WHRadj BMI with breast cancer
                      risk. Our study suggests that genetically determined obesity
                      and glucose/insulin-related traits have an important role in
                      the aetiology of breast cancer.},
