چکیده

Metabolic syndrome (mets) is more predominant in overweight, obese and minority populations. this study examined the prevalence of mets in an exclusively african-american (aa) cohort of breast cancer (bc) survivors; an underrepresented group in previous studies demonstrating negative bc outcomes disparities for females with mets. using a case-control design, overweight/obese aa women with treated stage i–iiia bc were matched 1:1 on age, race, sex, and body mass index (bmi) category with non-cancer population controls (n = 444). three of the following conditions were used to define mets: hdl cholesterol <50 mg/dl (1.3 mmol/l), serum triglycerides ≥150 mg/dl (1.7 mmol/l), blood glucose ≥100 mg/dl (or on treatment), waist circumference ≥88 cm, or ≥130 mmhg systolic or ≥85 mmhg diastolic blood pressure (or on treatment). matched-pairs analyses were conducted. for bc cases, most women had self-reported stage i (n = 76) or stage ii (n = 91) disease and were 6.9 (±5.2) years post-diagnosis. mets was significantly lower in bc survivors vs. their non-cancer population controls (43.2 vs. 51.4 %, respectively; p < 0.05). the diagnosis of mets did not differ by bmi stratification. a lower prevalence of ≥2 risk factors (80.2 vs. 85.6 %, p < 0.05) was observed for all cases vs. controls. while mets occurred less frequently in our bc cases vs. non-cancer controls, our estimates are nearly two times those reported in other bc survivors, suggesting important racial/ethnic differences. the prognostic implications of mets among aa bc survivors remain unknown and warrant further investigation.
