“…First, the results of this study showed that exercise significantly affected the obesity of the subject breast cancer patients. The results of this study were similar to those of the previous parallel cohort study [16] conducted in the U.S., which argued that physical activities and obesity significantly influence cancer development and death. Particularly, the results of this study showed that a subject who did strength exercise for more days per week had a lower chance of becoming obese.…”

The objectives of this study were to identify the factors affecting the obesity of breast cancer patients and to provide basic data for the development of an effective obesity management program for them using the propensity score matching method and data from the Korea National Health and Nutrition Examination Survey (KNHANES) with a bigger sample size and a higher level of representativeness. In this study, 231 breast cancer patients who had been diagnosed with breast cancer and had been treated for more than 3 months among the adult KNHANES participants (aged 19 and older) were selected. The results of this study showed that the degree of physical activity, the number of days of doing strength exercise, the food intake reduction level, the protein intake ratio, and the thermal effect of food affected the obesity of the breast cancer patients. Therefore, future studies are needed to examine the factors associated with the obesity management of breast cancer patients in various aspects, using a wide range of data, and to suggest political measures for managing the obesity of breast cancer patients.

“…The discussion of vegetable consumption was particularly infrequent in our study. Following healthy diets with an emphasis on plant‐based food consumption could protect from secondary cancers and decrease cancer related mortality . It was recently found that consuming vegetables is especially important for diversifying gut microbiome, which in turn lowers chronic inflammation, pain, fatigue, improves immunity, decreases tumorigenesis, and potentiates immunotherapeutic effects in cancer treatment and prevention …”

“…Weight loss recommendations in older obese and overweight survivors could play a major role in decreasing cancer related mortality, secondary obesity-related cancers, cancer recurrence, and comorbidities. 8,19,20 More research should investigate the reasons why these discussions are so infrequent. Societal stigma and provider discomfort discussing the sensitive nature of this subject matter might be reasons for infrequent discussion that could potentially be addressed.…”

Healthy lifestyle discussions between healthcare providers and older cancer survivors: Data from 12 cancer centers in the Southeastern United States

et al. 2019

BackgroundLittle is known about the prevalence of healthy lifestyle (HLS) discussions between providers and older cancer survivors.MethodsWe utilized cross‐sectional data from older cancer survivors (≥65 years) seen at 12 southeastern cancer centers during 2013‐2015. Data on demographics, time since diagnosis, weight, height, and healthy behaviors were collected. Respondents were asked if providers (oncologists, other physicians, and/or nurses) discussed exercise, healthy diet, weight management, and/or smoking cessation during clinical encounters. Descriptive statistics and bivariate associations between HLS topics and survivor characteristics were calculated.ResultsAmong 1460 cancer survivors, mean age was 74 years (SD 6), most were white (81%), and >1 year postdiagnosis (84%). The majority (71%) reported discussing at least one of three HLS topics (exercise 49%, healthy diet 53%, vegetable consumption 28%); 17% received counseling on all three. Weight loss was recommended to 33% of overweight/obese survivors and smoking cessation to 85% of current smokers. Oncologists and nurses discussed HLS less frequently compared to other physicians. Younger survivors (65‐74 years) received recommendations for exercise, weight loss, and tobacco cessation more often than older survivors (≥75 years). Compared to white respondents, minorities reported discussions on all topics more often except for tobacco cessation. Excluding tobacco cessation, survivors with recent cancer diagnoses (<1 year) reported HLS discussions more often than survivors >1 year postdiagnosis.ConclusionDespite the American Cancer Society's recommendations, older survivors reported a low prevalence of HLS discussions with their providers, with some variation by demographic groups. Strategies are needed to promote these important discussions in this population.

“…Studies of breast cancer mortality and survival rates have noted that adiposity is associated with reduced survival rates and higher rates of recurrence, irrespective of menopausal status and after adjustment for stage and treatment [68][69][70][71][72]. Additionally, obese patients with breast cancer often receive suboptimal treatment in terms of the doses of chemotherapy [73] and treatment appears to be less effective in patients with a BMI > 30 kg/m 2 [74].…”

Obesity and overweight are major health concerns and the leading preventable cause of death in developed and developing countries. Obesity affects men and women differently due to biological, socioeconomic, cultural and country-specific gender-related disparities. This book chapter outlines obesity as a risk factor for physical diseases and mental health disorders in women. Obesity has been shown to contribute to the risk of certain types of cancer, including breast, endometrial, gallbladder, oesophageal and renal cancer. In terms of reproductive health, obesity negatively affects both fertility and contraception. In addition, obesity is associated with early miscarriage, higher rates of caesarean section and high-risk obstetrical conditions, in addition to higher maternal and neonatal mortality rates, and congenital malformations. In terms of mental health, obesity is closely linked to depression, anxiety disorders, neurodegenerative diseases and sleep disorders. Socioeconomic, psychosocial and behavioural factors, factors associated with ageing, mechanisms related to the microbiome, gastrointestinal and vascular system, intracellular pathophysiology and metabolism in the body, hormones, adipocytokines and problems associated with medical treatment are important factors linking obesity with its negative consequences on physical and mental health.

Obesity, physical activity, and breast cancer survival among older breast cancer survivors in the Cancer Prevention Study-II Nutrition Cohort

Abstract: Higher BMI, pre- or post-diagnosis, was associated with a higher risk of BCSM in older patients, independent of comorbidities and stage at diagnosis. Weight management should be discussed even with women aged 65 years or older to lower rates of BCSM.
