In this cohort study of 1666 women with breast cancer, higher serum vitamin D levels were independently associated with better outcomes, including overall survival. Compared with women with the lowest third of 25-hydroxyvitamin D levels, those with the highest third had reduced hazards of all-cause death after full adjustment, and the associations were stronger in premenopausal women.

Maternal 25(OH)D concentrations >40 ng/mL associated with 60% lower preterm birth risk among general obstetrical patients at an urban medical center
PLOS ONE
This study found that maternal vitamin D concentrations greater than 40 ng/mL were associated with substantial reduction in pre-term birth risk in a large, diverse population of women. Women who had a serum concentration of 25(OH)D greater or equal to 40ng/mL had a 62% lower risk of preterm births.

Serum 25 HydroxyVitamin D Concentrations and the Risk of Hip Fractures: The Women's Health Initiative
Annals of Internal Medicine
In this study which looked at data from the Women’s Health Initiative, a 10 ng/ml decrease in vitamin D was associated with a 33% increased risk of hip fracture in multivariable models. Women with the lowest vitamin D levels had 72% increased odds of experiencing a hip fracture in comparison to women with the highest vitamin D levels.

Relationship between Low Ultraviolet B Irradiance and Higher Breast Cancer Risk in 107 Countries
The Breast Journal
This study showed that there is an increased rate of breast cancer further from the equator where there is less sunlight exposure. According to multiple regression, UVB irradiance was inversely associated with incidence rates after controlling for covariates. They also found that increasing serum 25(OH)D above 22 ng ⁄ mL was associated with incrementally lower incidence rates of breast cancer.
