Abstract
To assess body composition and lipid profile of women with and without breast cancer. We conducted a case-control study matched by age, including 62 women, 31 being newly diagnosed with breast cancer and 31 with benign breast changes. Data were collected through direct interview, with recording of sociodemographic characteristics, body composition assessment by anthropometry, including skinfolds (DC) and circumference, bioelectrical impedance (BIA) and ultrasonography (USG), as well as lipid profile evaluation. Kolmogorov-Smirnov test (normally distributed variables), "t" test, chi-square test for trend (Mann-Whitney U), chi-square test, Fisher's exact test and Yates correction and "odds ratio". When compared with controls, women with breast cancer (cases) had lower height (1.56 m ± 5.68 versus 1.59 m ± 6.92), p <0.03; higher percentage of body fat, assessed by Bioelectric Impedance (39.87% ± 8.26 versus 36.00% ± 6.85), p <0.049; and higher triceps skinfold thickness (27.55 mm ± 8.37 versus 22.81 ± 5.72 mm; p <0.01), respectively. Women with breast cancer had lower height, higher body fat percentage and higher triceps skinfold thickness. There was no difference in body mass index and waist circumference. There was no association between lipid profile and the occurrence of breast cancer.
Highlights
Breast cancer has been researched worldwide in recent years due to its high prevalence and incidence; it is the leading cause of cancer death among women[1], advances in early detection and new therapeutic forms used have evolved over the last decades[2].Among the aspects classically considered as risk factors for developing breast cancer are advanced age, low parity, early menarche, late menopause, obesity, alcoholism and increased height[3]
Among those linked to nutritional status, those related to body composition, such as obesity and/or overweight and inadequate distribution of body fat, especially in the post-menopause, are noteworthy[4]
Lipid profile seems to influence the development of female breast cancer, especially in the presence of an increased body mass index[5]
Summary
Breast cancer has been researched worldwide in recent years due to its high prevalence and incidence; it is the leading cause of cancer death among women[1], advances in early detection and new therapeutic forms used have evolved over the last decades[2]. Among the aspects classically considered as risk factors for developing breast cancer are advanced age, low parity, early menarche, late menopause, obesity, alcoholism and increased height[3]. Among those linked to nutritional status, those related to body composition, such as obesity and/or overweight and inadequate distribution of body fat, especially in the post-menopause, are noteworthy[4]. Lipid profile seems to influence the development of female breast cancer, especially in the presence of an increased body mass index[5]. The objective of this study was to determine the body composition and nutritional status of Brazilian women by using anthropometry and lipid profile. The individuals, with and without breast cancer, were from the mid-west region of the country an were followed by two reference centers in breast disease, belonging to the Goiás Mastology Research Network
