“…In the analysis of the incidence of being overweight, which was determined based on BMI, there is a consensus in the literature that the frequency of this factor is extremely high. This was observed by Brazilian authors [17][18][19]26 who detected excess weight in the range of 53.4-85.5% of women and by international studies 6,27 , which has data similar to that found in this study.…”

“…With regard to cardiovascular risk, it was observed that 84.5% of women had a very high risk, identified by WC ≥ 88 cm, which corroborates most breast cancer studies 18,19,26 . These findings show the need for health care in preventing the development of morbidities related to excess weight, especially in those patients who have a greater deposition for abdominal fat.…”

“…As for the sanitary housing location, only 19.6% did not have access to adequate basic sanitation, an aspect that has been little explored in surveys involving this public. However, Queiroz et al 18 , in Rio Grande do Norte, identified that almost half of their sample had poor basic sanitation, which stood out as one of the risk factors associated with breast cancer. This factor may also be associated with the most vulnerable social class and low education levels, which converge to make accessing health services difficult, especially in the northeast of Brazil.…”

Objective: To evaluate the nutritional status and the cardiovascular risk in women with breast cancer and identify factors associated with excessive body weight. Methods: A descriptive, cross-sectional, quantitative study was carried out in an oncology outpatient clinic and, gynecology/oncology wards at the Hospital das Clínicas da Universidade Federal de Pernambuco, from March to August 2019. The data analyzed was related to sociodemographic, gynecologic, clinic, anthropometric and lifestyle factors. Nutritional status was assessed using Body Mass Index, considering excessive body weight when > 25 kg/m2 for adults and > 27 kg/m2 for elderly. Obesity was considered > 30 kg/m2. Cardiovascular risk was defined by waist circumference (≥ 80 cm), neck circumference (≥ 34 cm) and waist-to-height ratio (> 0.5). Results: A total of 46 patients were included, with a mean age of 51.9 years, and the majority in outpatient follow-up. The population was mostly Caucasian women, who were married or in a civil union, who had had at least one pregnancy, were in menopause, and were sedentary. High frequencies of excessive body weight (76.1%) and obesity (43.5%) were observed, and anthropometric parameters revealed an elevated frequency of cardiovascular risk in this population, waist circumference (97.8%), neck circumference (84.8%), and waist-to-height ratio (95.7%). Unemployment (p = 0.020), and waist (p = 0.001) and neck (p = 0.001) circumferences were statistically associated factors to excessive body weight. Conclusions: The anthropometric profile of women with breast cancer indicated excess body weight and elevated cardiovascular risk, which suggests to the need for nutrition intervention and follow-up after the diagnosis.

“…Obesity and overweight are considered the most important modi able lifestyle-related risk factor among women, especially due to its impact on BC [6]. In studies that used anthropometric measures, obesity and overweight increased the overall risk of BC [15,19,20,22]. A recent study performed in Southern Brazil, associated obesity, respectively high BMI, to increased risk of BC among post-menopause women and to decreased risk of BC among pre-menopause women [11].…”

“…A recent case-control study of a population from Northeastern Brazil identi ed menarche age ≤12 years, one versus ≥2 children and time interval before rst and last gestation of >10 years as risk factors for BC, whereas total lifetime breastfeeding >24 month decreased the risk of BC [14]. Another recent study identi ed obesity and overweight as risk factor for BC [15].…”

Background: This case-control study was aimed at the identification of factors that modify breast cancer risk in a population from Northeastern Brazil. Breast cancer risk factors in this population are poorly understood. Methods: Data of 291 patients with invasive breast cancer and 291 healthy controls were obtained from medical records and personal interviews. Odds ratios (OR) and confidence intervals (CI) were determined using univariate and multiple regression analysis. Results: Oral contraceptive use increased the risk of breast cancer among pre- and post-menopause women 3.661 (95% CI: 1.81-7.39; p < 0.001) and 3.086 (95%CI: 1.85-5.79; p < 0.001) times. Family history increased the risk of breast cancer among pre- and post-menopause women 3.791 (95%CI: 1.85-7.77; p < 0.001) and 3.538 (95%CI: 2.16-5.79; p = 0.000) times. Risk of breast cancer among post-menopause women who regularly consumed alcohol was 4.21 (95%CI: 2.08-8.50; p < 0.001) times increased compared to women who did not consume alcohol. Obese and overweight post-menopause women had 2.117 (95%CI: 1.15-3.88) and 1.217 (95%CI: 0.74-2.19) times increased risk, compared to women with normal weight ( p = 0.044). Waist-to-hip ratio > 0.8 increased the risk of breast cancer among pre- menopause women 2.026 (0.94-4.38; p = 0.067) times in the univariate analysis. Nulliparous post-menopause women had 2.667 (95%CI: 1.30-5.50; p = 0.070) times increased risk. Univariate analysis of nulliparity among pre-menopause women indicated 2.59 (OR= 0.386; 95%CI: 0.15-0.98; p = 0.038) times decreased risk. Conclusions: Oral contraceptive use, family history and alcohol consumption increased the risk of breast cancer among pre- and post-menopause women. High body mass index increased the risk only among post-menopause women, whereas unadjusted high waist-to-hip ratio increased the risk of pre- menopause women. Nulliparous pre-menopause women tended to have decreased risk, whereas nulliparous post-menopause women tended to have increased risk of breast cancer.

Degree of food processing and breast cancer risk in black urban women from Soweto, South African: the South African Breast Cancer study

et al. 2022

This study aimed to investigate the association between consumption of ultra-processed foods, whole foods and breast cancer risk in black women from Soweto, South Africa. A population-based case (n 396)–control (n 396) study matched on age and residence, using data from the South African Breast Cancer study. Dietary intake was assessed using a validated quantified FFQ. Food items were categorised using the NOVA system ((1) unprocessed/minimally processed foods, (2) culinary ingredients, (3) processed foods and (4) ultra-processed foods). Conditional logistic regression models were used to estimate OR and 95 % CI of dietary contributions from each NOVA food group (as a percentage of total energy intake (EI)) and adjusting for potential confounders. Considering contributions to total EI per day, ultra-processed food consumption contributed to 44·8 % in cases and 47·9 % in controls, while unprocessed/minimally processed foods contributed to 38·8 % in cases and 35·2 % in controls. Unprocessed/minimally processed food consumption showed an inverse association with breast cancer risk overall (OR = 0·52, 95 % CI 0·35, 0·78), as well as in pre- and postmenopausal women separately (OR = 0·52, 95 % CI 0·27, 0·95 and OR = 0·55, 95 % CI 0·35, 0·89, respectively) and in women with progesterone positive breast cancer (OR = 0·23, 95 % CI 0·06, 0·86). There was no heterogeneity in association with breast cancer when analyses were stratified according to BMI. No significant associations were observed for the consumption of other NOVA food groups. Intake of unprocessed/minimally processed foods may reduce the risk of developing breast cancer in black women from Soweto, South Africa.
