| Abstract |
Epidemiologic findings are inconsistent regarding risk for breast cancer related to dairy consumption. We performed a meta-analysis of prospective cohort studies to examine the association between diary product consumption and risk of breast cancer. A PubMed database search through January 2011 was performed for relevant studies. We included prospective cohort studies that reported relative risks with 95% confidence intervals for the association of dairy consumption and breast cancer risk. A random effects model was used to calculate the summary risk estimates. We identified 18 prospective cohort studies eligible for analysis, involving 24,187 cases and 1,063,471 participants. The summary relative risk of breast cancer for the highest intake of total dairy food compared with the lowest was 0.85 (95% confidence interval: 0.76-0.95), with evidence of heterogeneity (P = 0.01, I (2) = 54.5%). For milk consumption, the summary relative risk was 0.91 (95% confidence interval: 0.80-1.02), and substantial heterogeneity was observed (P = 0.003, I (2) = 59.7%). Subgroup analyses based on limited numbers of studies suggested that the associations were somewhat stronger for low-fat dairy intake than for high-fat dairy intake and for premenopausal women than for postmenopausal women. There was a significant dose-response relationship of total dairy food, but not milk, consumption with breast cancer risk. Little evidence of publication bias was observed. In conclusion, findings of the present meta-analysis indicate that increased consumption of total dairy food, but not milk, may be associated with a reduced risk of breast cancer. |

Attention Score in Context
This research output has an Altmetric Attention Score of 437. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 21 February 2024.
All research outputs
#65,987
of 25,791,495 outputs
Outputs from Breast Cancer Research and Treatment
#10
of 5,007 outputs
Outputs of similar age
#151
of 121,107 outputs
Outputs of similar age from Breast Cancer Research and Treatment
#1
of 68 outputs
Altmetric has tracked 25,791,495 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 99th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 5,007 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.5. This one has done particularly well, scoring higher than 99% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 121,107 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 99% of its contemporaries.
We're also able to compare this research output to 68 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 98% of its contemporaries.
