“…Among them, the decrease in vegetable intake was about 102 g/d (>1 serving of 80 g). Previous studies generally observed an increase in vegetable intake among cancer survivors 15, 20, 21, 22, 23, 24, 26, 28. However, most of them were based on qualitative and/or retrospective data.…”

“…Dietary and alcohol intakes of cancer survivors have received increasing attention in the last decade 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29. Overall, these studies tended to suggest an improvement in dietary behavior after cancer diagnosis, as well as a strong motivation of cancer survivors to make lifestyle changes 4.…”

“…To our knowledge, only one study conducted in Norway provided prospective information on the variation of dietary and alcohol intakes between before and after cancer diagnosis,22 focusing on breast and colorectal cancers. Moreover, very few studies provided detailed data on variations of food and nutrient intakes between before and after diagnosis measured by validated quantitative dietary assessment tools 20, 22, 27…”

Postdiagnosis diet and alcohol consumption may be associated with cancer prognosis, recurrence and mortality. Our aim was to investigate food, nutrient and alcohol intake variations between before and after cancer diagnosis and their determinants in a prospective cohort. Subjects (n = 696) were incident cancer cases diagnosed in the NutriNet‐Santé cohort between 2009 and 2016. Food, nutrient and alcohol intakes were prospectively collected using repeated nonconsecutive 24‐hr dietary records since subjects' inclusion (i.e. an average of 2 y before diagnosis). Mean number of dietary records per subject was 5.9 before and 8.1 after diagnosis. All dietary data before and after diagnosis were compared by mixed models. Factors associated with the main dietary changes observed were also investigated using multivariable logistic regressions. We observed a decrease in intakes of vegetables (mean decrease in intake in patients who decreased their intake=‐102.4 ± 79.8 g/d), dairy products (–93.9 ± 82.8 g/d), meat/offal (–35.5 ± 27.8/d), soy products (–85.8 ± 104.1 g/d), sweetened soft drinks (–77.9 ± 95.4 g/d), and alcoholic drinks (–92.9 ± 119.9 g/d), and an increase in broths (42.1 ± 34.9 g/d) and fats/sauces (18.0 ± 13.4 g/d). We observed a decrease in energy intake (–377.2 ± 243.5 kcal/d) and in intakes of alcohol (–7.6 ± 9.4 g/d) proteins (–17.4 ± 12.5 g/d), and several vitamins (p < 0.05) and micronutrients (p < 0.05). Conversely, lipid (19.4 ± 14.6 g/d), SFA (9.3 ± 7.0 g/d), MUFA (8.3 ± 6.3 g/d) and vitamin E (3.9 ± 3.3 mg/d) intakes increased after diagnosis. This large prospective study suggests that cancer diagnosis is a key period for nutritional changes. It highlights some healthy behaviors such as a decrease in alcohol and sweetened drink consumption, but also less favorable trends, such as a decrease in vegetable consumption and in many vitamin and mineral intakes. These results provide insights to identify and target recommendations to put forward for better nutritional care of cancer survivors.

“…The authors found that women with breast cancer quit smoking more often than cancer-free women, while no signifi cant changes in alcohol consumption or BMI were observed. Beyond the scope of the study by Skeie et al (2009), further evidence is needed to identify the types of changes that women with breast cancer make compared to cancer-free women also in subgroups of women with specifi c characteristics and also evidence is needed on the treatment factors that characterise those women with breast cancer who makes the health behaviour changes in order to focus public health interventions.In this prospective study, we compared changes in BMI, alcohol and tobacco consumption following a breast cancer diagnosis in women with changes in cancer-free women. We hypothesised that women with breast cancer would make signifi cantly more behavioural changes to comply with the recommendations of the Danish National Board of Health (www.sst.dk) with regard to alcohol consumption [women should not consume more than 14 alcoholic beverages (1 drink is approximately 12 g alcohol) per week], weight control (BMI ϭ 18 -25 kg/m 2 ) and tobacco use (tobacco cessation) than cancer-free women.…”

Changes in body mass index and alcohol and tobacco consumption among breast cancer survivors and cancer-free women: A prospective study in the Danish Diet, Cancer and Health Cohort

Background . A breast cancer diagnosis has been suggested as a teachable moment when a woman is more open to making healthier lifestyle changes. Little is known about the health behaviour changes women with breast cancer initiate compared to those made by other women. Material and methods . We examined changes in body mass index (BMI) and tobacco and alcohol consumption among women with a diagnosis of breast cancer and among cancer-free women. We used data from 23 420 women aged 50 -64 years who participated in the Diet, Cancer and Health cohort, of whom 449 were diagnosed with breast cancer between baseline (1993 -1997) and follow-up (2000 -2002), and 22 971 remained cancer-free. We used multiple linear regression analysis to examine differences in BMI and alcohol and tobacco consumption between the two groups and to examine whether demographic and prognostic factors were associated with behavioural changes in women with breast cancer. Results . There were no signifi cant differences in changes in BMI, alcohol and tobacco consumption between the two groups. Only in sub-analyses among women who lost weight between baseline and follow-up, women with breast cancer lost more weight than cancer-free women ( β ϭ 0.2; CI 0.1; 0.4), but residual confounding from stage cannot be excluded. Among the women with breast cancer we found no signifi cant changes in BMI, alcohol and tobacco consumption by level of education, marital status, chemotherapy, hormone therapy or radiation. Conclusion . Women with breast cancer did not reduce their BMI, or modify their alcohol use or tobacco consumption compared with cancer-free women. This study indicates that guidelines and interventions to change health behaviour are needed after a cancer diagnosis.Breast cancer is the most frequent cancer and the most frequent cause of death from cancer among women worldwide [1]. In Denmark, as in many other western countries, increasing breast cancer incidence and an improved fi ve-year survival rate of 85% [2] implies that a large proportion of women with breast cancer survive for many years beyond their initial treatment. It is therefore relevant to examine factors that could impact breast cancer survival and quality of life. Health behaviour including changes in body mass index (BMI), alcohol and tobacco consumption may be important not only for reducing breast cancer risk but also for survival [3,4] and quality of life [5], but knowledge on whether women with breast cancer do make more health behaviour changes compared to other women is limited.Most studies on health behaviour have addressed only changes in diet and physical activity [6] and most of the studies evaluating changes in alcohol and tobacco use and BMI were retrospective [5], therefore, possibly involving recall bias. We only identifi ed one prospective study that focused mainly on dietary change, but also included changes in BMI, alcohol and tobacco consumption following [7]. The authors found that women with breast cancer quit smoking more often than cancer-free wome...

Many studies have demonstrated that lifestyle factors, including diet, may influence cancer survival. The number of cancer survivors is increasing worldwide and little is known about long-term diet changes in people who had cancer. We studied 53,981 women from the prospective E3N-EPIC cohort study with available dietary data in 1993 and 2005, among whom 4,619 had a cancer diagnosis inbetween (including n = 2,699 breast cancers). We evaluated the potential impact of a cancer diagnosis (comparing women with cancer to women with no cancer) on changes in FV consumption using multivariable linear regression models considering cancer site, stage at diagnosis and socioeconomic factors. Compared to women with no cancer, a statistically significant increase in FV consumption (β=+2.65%, [1.22-4.09]) was observed in women who had cancer, and this association appeared to be driven by breast cancer exclusively. The increase in FV consumption was larger in women who had an advanced stage of breast cancer (stages II-IV) (β=+7.23%, [3.92-10.5]) than in women with stages 0-I (β=+2.03%, [-0.20 to 4.26]). Women with no partner and no children were those having the highest increase in FV consumption (β=+18.71%, [6.51-30.91]). These changes were only observed in specific SE groups. When considering adherence to guidelines, the proportion of women who consumed less than 7.5 portions a day in 1993 and more in 2005 was greater in women with advanced breast cancer. More research is now needed to understand how the inequities we observed impact the long-term health after cancer.

Dietary change among breast and colorectal cancer survivors and cancer-free women in the Norwegian Women and Cancer cohort study

Abstract: Cancer survivors showed little change toward cancer-preventive guidelines, although more advanced stage and being more than 2.4 years post diagnosis was associated with greater change in diet and smoking behaviors.
