Background: Many cancer survivors experience declines in health-related quality of life (HRQOL) and increases in fatigue as a result of cancer and its treatment. Exercise is linked to improvements in these outcomes, but little is known about the role of sedentary behavior. In a large, ethnically-diverse cohort of breast cancer survivors, we examined the relationship between sedentary time, HRQOL, and fatigue, and examined if that relationship differed by recreational moderate-vigorous physical activity (MVPA) level. Methods: Participants were 710 women diagnosed with stage 0-IIIA breast cancer in the Health, Eating, Activity, and Lifestyle Study. Women completed questionnaires at approximately 30-months postdiagnosis (sedentary time; recreational MVPA) and 41-months postdiagnosis (HRQOL; fatigue). In multivariate models, we regressed these outcomes linearly on quartiles of daily sedentary time, and a variable jointly reflecting sedentary time quartiles and MVPA categories (0; >0 to <9; ?9 MET-hrs/wk). Results: Sedentary time was not independently related to subscales or summary scores of HRQOL or fatigue. In addition, comparisons of women with high vs. low (Q4:Q1) sedentary time by MVPA level did not result in significant differences in HRQOL or fatigue. Conclusion: In this breast cancer survivor cohort, self-reported sedentary time was not associated with HRQOL or fatigue, 3.5 years postdiagnosis. HubMed – eating

PURPOSE: It is demonstrated that aerobic exercise plays an important role in weight loss programs for obesity by increasing 24 h metabolic rate. While aerobic exercise can result in health and fitness benefits in obese subjects, also independently of weight loss, not completely clear are the effects of bouts of hard exercise on metabolic outcomes. The aim of this study was to test the hypothesis that short-term aerobic activity with anaerobic bouts might result in a greater improvement in the management of obesity than aerobic activity alone. METHODS: We studied 16 obese subjects (eight men) during a progressive cycloergometric test up to exhaustion, before and after 4 weeks of two different training schedules (6 days/week). Insulin and glycaemia, non-esterified fatty acids (NEFA) and lactic acid were sampled. Group A (eight subjects, four men) performed an aerobic cycle workout; Group B (eight subjects, four men) performed a 25 min aerobic workout followed by 5 min of anaerobic workout. All the subjects maintained their individual eating habits. RESULTS: The post-training test showed a decrease in AUCs NEFA in Group A (p < 0.05) and an increase in Group B (p < 0.05), together with an increase in lactic acid in Group A and a decrease in Group B (p < 0.01). ?-cell function (HOMA2-B) revealed a reduction only in Group A (p < 0.05). Group B achieved a greatest reduction in body fat mass than Group A (p < 0.05). CONCLUSIONS: Aerobic plus anaerobic training seem to produce a greater response in lipid metabolism and not significant modifications in glucose indexes; then, in training prescription for obesity, we might suggest at starting weight loss program aerobic with short bouts of anaerobic training to reduce fat mass and subsequently a prolonged aerobic training alone to ameliorate the metabolic profile.

Caregiver-Reported Neuropsychiatric Symptoms in Patients Undergoing Treatment for Head and Neck Cancer: A Pilot Study.

BACKGROUND:: Patients with cancer experience multiple neuropsychiatric symptoms. Whereas individual symptoms have been studied in patients with head and neck cancer, the broader context of neuropsychiatric symptoms needs to be explored. OBJECTIVE:: The aims of this pilot study were to (a) determine the caregiver-reported prevalence and severity of neuropsychiatric symptoms in patients with head and neck cancer, (b) determine the associated level of caregiver distress, and (c) describe the effects of neuropsychiatric symptoms on patients and their caregivers. METHODS:: Twenty-three family caregivers of patients with head and neck cancer completed the Neuropsychiatric Inventory Questionnaire and participated in a semistructured interview. RESULTS:: All caregivers reported that patients experienced at least 1 neuropsychiatric symptom (mean, 7.5; range, 1-12). The most frequently reported symptoms were trouble with appetite and eating (95.7%), altered nighttime behaviors (82.6%), depression/dysphoria (78.3%), decreased alertness (69.6%), inattention (60.9%), apathy/indifference (56.5%), anxiety (56.5%), irritability/lability (52.5%), agitation/aggression (52.2%), and slowed behavior (43.5%). The mean severity rating for 9 symptoms was moderate to severe. Most symptoms caused mild to moderate levels of caregiver distress. Qualitative data indicated that neuropsychiatric symptoms negatively affected patients, their caregivers, and other family members. Patients required more caregiver support resulting in increased caregiver burden and distress. CONCLUSIONS:: Neuropsychiatric symptoms are common and troubling in patients with head and neck cancer during treatment. Further investigation of their effects on patients and family caregivers is needed. IMPLICATIONS FOR PRACTICE:: Clinicians should monitor for and treat neuropsychiatric symptoms throughout treatment and provide caregiver and patient education and support. HubMed – eating


Effects of habit on intentional and reactive motivations for unhealthy eating.

This study examined the effect of unhealthy eating habits on behavior within the dual-process perspective, including intentional and reactive motivation. Previous studies assumed that habits elicit behavior directly. However, this study hypothesized that habits affect behavior through their effect on action control and reactive motivation. Longitudinal data were available from undergraduate students (n = 286) who completed the first questionnaire assessing their habits, action control (internal and external), intentional motivation, and reactive motivation, and the second questionnaire accessing their actual eating behavior of high-calorie snacks in the two weeks following the first questionnaire. Structural equation modeling was used to examine the predictors of their eating behavior. The results showed that habits inhibited internal control and promoted external control. These two sources of control affected intentional and reactive motivations, respectively, which determine behavior. It is concluded that habitual unhealthy eating behavior results from a decrease in conscious control leading to a switch from an intentional to a reactive route. HubMed – eating
