The Effects of Diet and Dietary Interventions on the Quality of Life among Breast Cancer Survivors: A Cross-Sectional Analysis and a Systematic Review of Experimental Studies.

ABSTRACT: There is an ongoing need for solid evidence about the effects of healthy behaviors, and particularly diet, on the quality of life (QoL) among breast cancer survivors. We first conducted a cross-sectional study on 68 Italian stage I-III breast cancer survivors, to investigate the association of adherence to the Mediterranean diet (MD), physical activity and weight status with QoL. Adherence to MD and physical activity was assessed using structured questionnaires. QoL was assessed using the European Organization for the Research and Treatment of Cancer Quality-of-Life tools. We showed that low consumption of red meat and carbonated beverages, daily consumption of wine and high consumption of dishes seasoned with sofrito had beneficial effects on several QoL subscales. By contrast, using olive oil as the main culinary fat, low consumption of commercial sweets and high consumption of nuts were associated with negative effects. Overall, these findings resulted in a null effect of adherence to MD on QoL. Furthermore, we observed better QoL sub-scores among women who performed moderate physical activity (i.e., diarrhea) and those who were underweight/normal weight (i.e., physical functioning and dyspnea) if compared with their counterparts (p-values ? 0.003 after correction for multiple comparison). Next, we performed a systematic review of nine experimental studies to summarize whether dietary interventions might improve QoL among breast cancer patients. All the studies demonstrated significant improvements in overall QoL and/or its subscales after the interventions. However, differences in study design, interventions and tools used for QoL assessment did not allow us to provide an overall estimate. Moreover, only a single-arm trial evaluated the effect of an exclusive dietary-based intervention, while others combined dietary recommendations with physical activity and weight loss programs. For these reasons, our study encourages more efforts to improve the robustness of current evidence, through more homogenous tools, larger population-based studies and further randomized controlled trials.

Project description:BACKGROUND:Modifiable lifestyle factors, such as diet quality, could reduce inflammation and improve quality of life (QOL) in breast cancer survivors, but data are inconclusive. OBJECTIVE:To determine whether diet quality, as measured by Healthy Eating Index-2010 (HEI-2010) score, is associated with inflammation, health status, or functional outcomes affecting QOL in survivors of early-stage breast cancer. DESIGN:This is a cross-sectional, secondary analysis of baseline data collected from breast cancer survivors after completion of primary therapy and before random assignment to a pilot nutritional intervention aimed at reducing side effects of aromatase inhibitor treatment. PARTICIPANTS/SETTING:Participants were 44 postmenopausal women with stage I to III endocrine receptor-positive breast cancer receiving outpatient care at a midwestern cancer center between November 2011 and October 2013. MAIN OUTCOME MEASURES:Primary outcomes were serum proinflammatory cytokines (interleukin-6 [IL-6], IL-17, and tumor necrosis factor-? receptor 2 [TNFR-2]). Secondary outcomes included QOL measured by the Stanford Health and Disability Questionnaire and the Functional Assessment of Cancer Therapy-Breast with Endocrine Subscale. STATISTICAL ANALYSES PERFORMED:Pearson correlation coefficients (r) and linear regression models were used to evaluate the relationship of dietary variables with inflammatory cytokines and QOL measures. RESULTS:A higher overall HEI-2010 score (healthier diet) was associated with lower IL-6 (r=-0.46; P=0.002) and TNFR-2 (r=-0.41; P=0.006); however, associations were attenuated by body mass index (BMI) (IL=6 [r=-0.26; P=0.10]; TNFR-2 [r=-0.30; P=0.06]). In women with prior chemotherapy, a higher HEI-2010 score was strongly associated with lower IL-6 (r=-0.67; P=0.009) and TNFR-2 (r=-0.59; P=0.03) after BMI adjustment. There were no significant correlations between HEI-2010 score and QOL measures after adjustment for BMI. CONCLUSIONS:These data suggest the need for more rigorous investigation into the relationship of diet quality, BMI, and inflammation in breast cancer survivors.

Project description:Diet quality indices score dietary intakes against recommendations, whereas dietary patterns consider the pattern and combination of dietary intakes. Studies evaluating both methodologies in relation to cardiometabolic health in a nationally representative sample are limited. The aim of the present study was to investigate the relationship between diet quality, dietary patterns and markers of cardiometabolic health in Australian adults.Dietary data, using two 24-h dietary recalls, were collected from adults in the cross-sectional Australian Health Survey 2011-2013 (n?=?2121; 46.4 (SE 0.48) years). Diet quality was estimated using the Dietary Guideline Index (DGI). Dietary patterns (DPs), derived using reduced rank regression, were estimated using fiber density, SFA: PUFA and total sugars intake as intermediate markers. Multi-variable adjusted linear regression analyses were used to examine associations between diet quality and DPs and blood biomarkers, body mass index, waist circumference, diastolic and systolic blood pressure and an overall cardiometabolic risk score.DGI was associated with lower glucose (coef -?0.009, SE 0.004; P-trend?=?0.033), body mass index (coef -?0.017, SE 0.007; P-trend?=?0.019) and waist circumference (coef -?0.014, SE 0.005; P-trend?=?0.008). Two dietary patterns were derived: dietary pattern-1 was characterized by higher intakes of pome fruit and wholegrain bread, while dietary pattern-2 was characterized by higher intakes of added sugars and tropical fruit. Dietary pattern-1 was associated with lower body mass index (coef -?0.028, SE 0.007; P-trend<?0.001) and waist circumference (coef -?0.017, SE 0.005; P-trend?=?0.001). There was a trend towards lower cardiometabolic risk score. Dietary pattern-2 was associated with lower HDL-cholesterol (coef -?0.026, SE 0.012; P-trend?=?0.028). There was a trend towards lower diastolic blood pressure. No associations with other markers were observed.Better diet quality and healthier dietary patterns were primarily associated with favorable anthropometric markers of cardiometabolic health. Findings support the need for comparison of whole-diet based methodologies that take into consideration the interactions between foods and nutrients. Longitudinal studies are warranted to better understand causal relationships between diet and cardiometabolic health.

Project description:Hematopoietic stem cell transplantation (HCT) survivors are burdened by a high prevalence and early onset of chronic diseases. Healthy dietary patterns have been associated with lower risks of chronic health conditions in the general population. HCT survivors are susceptible to multiple complications that may result in chronic illness. Unfortunately, no study to date has comprehensively documented the adherence of HCT survivors to the Dietary Guidelines for Americans (DGA), which are designed specifically to provide guidance for making healthy food choices. The primary aim of this study was to evaluate diet quality and nutrient intake adequacy of HCT survivors. A secondary aim was to assess these survivors' willingness to take part in a future dietary intervention. The dietary intake of adults who had undergone autologous or allogeneic HCT for a hematologic disease and were at least 1 year post-transplantation was assessed using the Block 2014 food frequency questionnaire, and diet quality was estimated using the Healthy Eating Index 2015. Nutrient intake adequacies of the group were estimated by the estimated average requirement cutpoint method. Survivors' (n = 90) HEI-2015 scores averaged 61.6 ± 1.1. Adherence to a good-quality diet was reported by only 10% of survivors. Intakes of vitamins A, C, and D, as well as magnesium and calcium, suggested inadequacy. Fiber intake at 8.9 g per 1000 kcal/day fell below the recommended adequate intake. "Change in taste" was associated with lower quality of diet (P = .02). HCT survivors within 2 years post-transplantation were more receptive than survivors beyond 2 years to participating in a dietary intervention (95% versus 65%; P = .0013). Adult HCT survivors reported less-than-optimal adherence to the 2015-2020 DGA and had numerous shortfall nutrient intakes; however, their willingness to participate in a dietary intervention was relatively high. These findings reinforce the need to incorporate nutrition into HCT survivor care.
