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.},
