“The objective was to compare the nutritional status and the risk of metabolic complications associated with obesity among women with and without breast cancer. Case-control study conducted with women with breast cancer attending the Mastology Program of a federal public hospital in Goiânia, Goiás and their age-matched controls. A nutritional status assessment was held by weight measurement (kg), height (m), body mass index (BMI: kg / m2) and the measurement of waist circumference (WC: cm), using anthropometric techniques previously standardized. To compare the differences between groups the t-test and chi-square test were used, adopting p <0.05. The study included 256 women, 90 cases and 166 controls, middle age 52.6 ± 11.1 years. The nutritional status in women up to 60 years in both groups, only 21.1% in the case group and 25.3% in the control group were classified as normal weight, according to BMI, while almost half of the case and control patients, 44.4% and 42.2% were overweight, respectively. Regarding the nutritional status of older women, 63.7% of patient cases and 65.0% of patient controls were overweight. In both situations, there was no significant difference between groups (p = 0.23 and p = 0.81, respectively). Analyzing the WC, as a central adiposity indicator, it was observed that the average from case group (93.6 ± 11.6 cm) and from control group (89.5 ± 12.3 cm) was different between them (p = 0.01), ranking them with much increased risk for metabolic diseases associated with obesity. The cases had a higher prevalence of this risk (63.95%) compared to controls (54.58%) (p = 0.08), no statistically significant difference. Women with and without breast cancer had increased prevalence of overweight, especially the elderly, and those with this disease were classified at higher risk for metabolic complications associated with obesity, aspects that impact negatively the prognosis of breast cancer.
