Association of Mammographic Breast Density with Dairy Product Consumption, Sun Exposure, and Daily Activity

Abstract

Background. Mammographic density is a risk factor, for breast cancer and its association with various factors is under investigation; we carried out a study to assess its relationship with daily dairy intake, sun exposure, and physical activities. Patients and Methods. Women ≥40 years of age were interviewed about habits of dairy product consumption, daily sun exposure and physical activity. Exclusion criteria consisted of history of breast cancer, consumption of calcium and vitamin D supplements, hormone replacement therapy, or renal disease. Mammographic densities were classified according to the classification system of the American College of Radiologists into 4 classes. Results. Overall 703 cases were entered in the study. The mean age was 48.2 ± 6.2 years. The most common and least frequent classes of mammographic density were classes 2 and 4, respectively. There was no significant association between mammographic density and rate of dairy consumption, amount of sunlight exposure, and daily physical activity. Conclusion. Relation of sunlight exposure and intake of milk products with mammographic density need further study, while the subject of physical activity can be evaluated by a systematic review and meta-analysis of the existing literature.

Evaluation of the association of endometriosis and mammographic breast density, a cross-sectional study

“…However, this relation has been highly demonstrated for the former [ 29 ], but not in the latter condition [ 30 ]. Also, use of dairy products might lower the risk of endometriosis [ 31 ], while the few studies about the association of these products with MBD have showed controversial results from no relation to a negative association [ 32 ].…”

Dairy intake is associated with memory and pulsatility index in heart failure

“…Prospective studies employing objective measures specific to high and low-fat dairy are needed to clarify these possibilities. Past work has incorporated such measures as detailed questionnaires and daily food diaries to better understand high vs. low-fat diets [39][40][41], and these same measures can be used in studies examining dairy intake, physical activity, and cognition.…”

Coffee, Tea, and Mammographic Breast Density in Premenopausal Women

“…To have a greater understanding of the determinants of breast density, especially those that can be modified, studies have investigated the associations of adult diet and dietary factors with MBD. Results from those studies have, however, been largely null [7][8][9][10].…”
