RESUMO
INTRODUCTION: The objective of this study was to examine workplace determinants of obesity and participation in employer-sponsored wellness programs among low-wage workers. METHODS: We conducted key informant interviews and focus groups with 2 partner organizations: a health care employer and a union representing retail workers. Interviews and focus groups discussed worksite factors that support or constrain healthy eating and physical activity and barriers that reduce participation in workplace wellness programs. Focus group discussions were transcribed and coded to identify main themes related to healthy eating, physical activity, and workplace factors that affect health. RESULTS: Although the union informants recognized the need for workplace wellness programs, very few programs were offered because informants did not know how to reach their widespread and diverse membership. Informants from the health care organization described various programs available to employees but noted several barriers to effective implementation. Workers discussed how their job characteristics contributed to their weight; irregular schedules, shift work, short breaks, physical job demands, and food options at work were among the most commonly discussed contributors to poor eating and exercise behaviors. Workers also described several general factors such as motivation, time, money, and conflicting responsibilities. CONCLUSION: The workplace offers unique opportunities for obesity interventions that go beyond traditional approaches. Our results suggest that modifying the physical and social work environment by using participatory or integrated health and safety approaches may improve eating and physical activity behaviors. However, more research is needed about the methods best suited to the needs of low-wage workers.

Persistent disparities in cancer screening by race/ethnicity and socioeconomic status require innovative prevention tools and techniques. Behavioral economics provides tools to potentially reduce disparities by informing strategies and systems to increase prevention of breast, cervical, and colorectal cancers. With an emphasis on the predictable, but sometimes flawed, mental shortcuts (heuristics) people use to make decisions, behavioral economics offers insights that practitioners can use to enhance evidence-based cancer screening interventions that rely on judgments about the probability of developing and detecting cancer, decisions about competing screening options, and the optimal presentation of complex choices (choice architecture). In the area of judgment, we describe ways practitioners can use the availability and representativeness of heuristics and the tendency toward unrealistic optimism to increase perceptions of risk and highlight benefits of screening. We describe how several behavioral economic principles involved in decision-making can influence screening attitudes, including how framing and context effects can be manipulated to highlight personally salient features of cancer screening tests. Finally, we offer suggestions about ways practitioners can apply principles related to choice architecture to health care systems in which cancer screening takes place. These recommendations include the use of incentives to increase screening, introduction of default options, appropriate feedback throughout the decision-making and behavior completion process, and clear presentation of complex choices, particularly in the context of colorectal cancer screening. We conclude by noting gaps in knowledge and propose future research questions to guide this promising area of research and practice.

In light of the obesity epidemic, there is growing interest in the use of financial incentives for dietary behavior change. Previous reviews of the literature have focused on randomized controlled trials and found mixed results. The purpose of this systematic review is to update and expand on previous reviews by considering a broader range of study designs, including randomized controlled trials, quasi-experimental, observational, and simulation studies testing the use of financial incentives to change dietary behavior and to inform both dietetic practice and research. The review was guided by theoretical consideration of the type of incentive used based on the principles of operant conditioning. There was further examination of whether studies were carried out with an institutional focus. Studies published between 2006 and 2012 were selected for review, and data were extracted regarding study population, intervention design, outcome measures, study duration and follow-up, and key findings. Twelve studies meeting selection criteria were reviewed, with 11 finding a positive association between incentives and dietary behavior change in the short term. All studies pointed to more specific information on the type, timing, and magnitude of incentives needed to motivate individuals to change behavior, the types of incentives and disincentives most likely to affect the behavior of various socioeconomic groups, and promising approaches for potential policy and practice innovations. Limitations of the studies are noted, including the lack of theoretical guidance in the selection of incentive structures and the absence of basic experimental data. Future research should consider these factors, even as policy makers and practitioners continue to experiment with this potentially useful approach to addressing obesity.

PURPOSE: Breast cancer treatments (chemotherapy and hormone therapy) can cause a rapid loss in bone mineral density, leading to osteoporosis and fractures later in life. Fortunately, preventative measures (vitamin D, exercise, etc.) can delay bone loss if employed early enough. This study compares the prevalence of osteoporosis and osteoporosis-related discussions with physicians among female breast cancer survivors and females with no cancer history to determine if breast cancer patients are being correctly advised on their high risk of bone loss. METHODS: The 2003 Medicare Current Beneficiary Survey, a nationally representative sample of 550 women with a breast cancer history and 6,673 women with no cancer history aged ≥65, was used. The first set of dependent variables collected information on bone health (osteoporosis, falls, and fractures). The second set of dependent variables collected information on bone health discussions with their physician. Multivariate logistic regression models were used to evaluate whether breast cancer was independently associated with bone health issues. RESULTS: After adjustment for confounders, a breast cancer diagnosis was found to be associated with a higher prevalence of an osteoporosis diagnosis over their lifetime (adjusted odds ratio (OR(adj)) = 1.32, 95 % confidence interval (95 % CI) = 1.08-1.61) and falls in the previous year (OR(adj) = 1.23, 95 % CI = 1.01-1.51) compared to respondents without a cancer diagnosis. However, breast cancer respondents were not more likely than respondents without a cancer diagnosis to discuss osteoporosis with their physician (OR(adj) = 1.20, 95 % CI = 0.96-1.50) or be told they are at high risk for osteoporosis (OR(adj) = 1.41, 95 % CI = 0.95-2.10). CONCLUSIONS: A breast cancer diagnosis was associated with an increased prevalence of osteoporosis and falls. Nevertheless, breast cancer respondents were not more likely to discuss osteoporosis with their physician nor were they more likely to be considered high risk for osteoporosis. Increased dialogue between physician and breast cancer patient pertaining to bone loss is needed.

PURPOSE: Characterize mobile technology ownership, use, and relationship to self-reported cancer prevention behaviors and health status in a diverse, low-income sample of callers to 2-1-1. DESIGN: Secondary analyses of cross-sectional survey data from a larger trial collected from June 2010 to December 2012. SETTING: United Way Missouri 2-1-1 serves 99 of 114 counties and received 166,000 calls in 2011. SUBJECTS: The respondents (baseline, n = 1898; 4 month, n = 1242) were predominantly female, non-Hispanic Black, younger than 50 years, with high-school education or less and annual income <$20,000. MEASURES: Cell phone ownership and use and its relationship to cancer prevention services and health status were assessed via telephone-based survey, using items adapted from previous research and the Behavioral Risk Factor Surveillance System. Smartphone ownership and use were also assessed. ANALYSIS: Descriptive statistics and bivariate and multivariate associations between cell phone ownership and prevention and health status are reported. RESULTS: Three-fourths (74%) of study participants owned a cell phone and 23% owned a smartphone. Text messaging was the most popular use. Ownership was significantly associated with good to excellent health status and presence of smoke-free home policies in multivariate models. CONCLUSION: Cell phone ownership is growing and has potential to deliver health information to low-income populations. With 16 million calls annually, the national 2-1-1 system may be a promising model and platform.

BACKGROUND: Callers to 2-1-1 have greater need for and lesser use of cancer control services than other Americans. Integrating cancer risk assessment and referrals to preventive services into 2-1-1 systems is both feasible and acceptable to callers. PURPOSE: To determine whether callers will act on these referrals. METHODS: In a randomized trial, 2-1-1 callers (n=1200) received standard service and those with at least one cancer risk factor or need for screening were assigned to receive verbal referrals only, verbal referrals + a tailored reminder mailed to their home, or verbal referrals + a telephone health coach/navigator. All data were collected from June 2010 to March 2012 and analyzed in March and April 2012. RESULTS: At 1-month follow-up, callers in the navigator condition were more likely to report having contacted a cancer control referral than those receiving tailored reminders or verbal referrals only (34% vs 24% vs 18%, respectively; n=772, p<0.0001). Compared to verbal referrals only, navigators were particularly effective in getting 2-1-1 callers to contact providers for mammograms (OR=2.10, 95% CI=1.04, 4.22); Paps (OR=2.98, 95% CI=1.18, 7.54); and smoking cessation (OR=2.07, 95% CI=1.14, 3.74). CONCLUSIONS: Given the extensive reach of 2-1-1s and the elevated risk profile of their callers, even modest response rates could have meaningful impact on population health if proactive health referrals were implemented nationally.

Innovative interventions are needed to connect underserved populations to cancer control services. With data from Missouri, North Carolina, Texas, and Washington this study a) estimated the cancer control needs of callers to 2-1-1, an information and referral system used by underserved populations, b) compared rates of need with state and national data, and c) examined receptiveness to needed referrals. From October 2009 to March 2010 callers' (N=1,408) cancer control needs were assessed in six areas: breast, cervical, and colorectal cancer screening, HPV vaccination, smoking, and smoke-free homes using Behavioral Risk Factor Surveillance System (BRFSS) survey items. Standardized estimates were compared with state and national rates. Nearly 70% of the sample had at least one cancer control need. Needs were greater for 2-1-1 callers than for state and national rates, and callers were receptive to referrals. 2-1-1 could be a key partner in efforts to reduce cancer disparities.

OBJECTIVES: We examined the association between perceived discrimination and smoking status and whether psychological distress mediated this relationship in a large, multiethnic sample. METHODS: We used 2004 through 2008 data from the Behavioral Risk Factor Surveillance System Reactions to Race module to conduct multivariate logistic regression analyses and tests of mediation examining associations between perceived discrimination in health care and workplace settings, psychological distress, and current smoking status. RESULTS: Regardless of race/ethnicity, perceived discrimination was associated with increased odds of current smoking. Psychological distress was also a significant mediator of the discrimination-smoking association. CONCLUSIONS: Our results indicate that individuals who report discriminatory treatment in multiple domains may be more likely to smoke, in part, because of the psychological distress associated with such treatment.

Patient navigation requires that patient load be equitably distributed. We examined whether navigators could predict the relative amount of time needed by different patients for navigation. Analysis of 139 breast and colorectal cancer patients randomized to the navigation arm of a trial evaluating the effectiveness of navigation. Navigators completed a one-item scale estimating how much navigation time patients were likely to require. Participants were mostly females (89.2%) with breast cancer (83.4%); barriers to cancer care were insurance difficulties (26.6%), social support (18.0%), and transportation (14.4%). Navigator baseline estimates of navigation intensity predicted total navigation time, independent of patient characteristics. The total number of barriers, rather than any specific type of barrier, predicted increased navigator time, with a 16% increase for each barrier. Navigators' estimate of intensity independently predicts navigation time for cancer patients. Findings have implications for assigning navigator case loads.

Vitamin D deficiency in the patients treated for breast cancer is associated with numerous adverse effects (bone loss, arthralgia, and falls). The first aim of this study was to assess vitamin D status, determined by 25-OH vitamin D levels, among women diagnosed with breast cancer according to demographic/clinical variables and bone mineral density (BMD). The second aim of this study was to evaluate the effect of daily low-dose and weekly high-dose vitamin D supplementation on 25-OH vitamin D levels. This retrospective study included 224 women diagnosed with stage 0-III breast cancer who received treatment at the James P. Wilmot Cancer Center at the University of Rochester Medical Center. Total 25-OH vitamin D levels (D(2) + D(3)) were determined at baseline for all participants. Vitamin D deficiency was defined as a 25-OH vitamin D level < 20 ng/ml, insufficiency as 20-31 ng/ml, and sufficiency as ≥32 ng/ml. BMD was assessed during the period between 3 months before and 6 months following the baseline vitamin D assessment. Based on the participants' baseline levels, they received either no supplementation, low-dose supplementation (1,000 IU/day), or high-dose supplementation (≥50,000 IU/week), and 25-OH vitamin D was reassessed in the following 8-16 weeks. Approximately 66.5% had deficient/insufficient vitamin D levels at baseline. Deficiency/insufficiency was more common among non-Caucasians, women with later-stage disease, and those who had previously received radiation therapy (P < 0.05). Breast cancer patients with deficient/insufficient 25-OH vitamin D levels had significantly lower lumbar BMD (P = 0.03). Compared to the no-supplementation group, weekly high-dose supplementation significantly increased 25-OH vitamin D levels, while daily low-dose supplementation did not significantly increase levels. Vitamin D deficiency and insufficiency were common among women with breast cancer and associated with reduced BMD in the spine. Clinicians should carefully consider vitamin D supplementation regimens when treating vitamin D deficiency/insufficiency in breast cancer patients.

INTRODUCTION: African American men have the highest rates of prostate cancer of any racial group, but very little is known about the psychological functioning of African American men in response to prostate cancer diagnosis and treatment. PURPOSE: In this secondary analysis of a national trial testing a psychological intervention for prostate cancer patients, we report on the traumatic stress symptoms of African American and non-African American men. METHODS: This analysis includes 317 men (African American: n = 30, 9%; non-African American: n = 287, 91%) who were enrolled in the intervention trial, which included 12 weeks of group psychotherapy and 24 months of follow-up. Using mixed model analysis, total score on the Impact of Events Scale (IES) and its Intrusion and Avoidance subscales were examined to determine mean differences in traumatic stress across all time points (0, 3, 6, 12, 18, and 24 months). In an additional analysis, relevant psychosocial, demographic, and clinical variables were added to the model. RESULTS: Results showed significantly higher levels of traumatic stress for African American men compared to non-African American men in all models independently of the intervention arm, demographics, and relevant clinical variables. African Americans also had a consistently higher prevalence of clinically significant traumatic stress symptoms (defined as IES total score ≥ 27). These elevations remained across all time points over 24 months. CONCLUSIONS: This is the first study to show a racial disparity in traumatic stress specifically as an aspect of overall psychological adjustment to prostate cancer. Recommendations are made for appropriate assessment, referral, and treatment of psychological distress in this vulnerable population.

PURPOSE: Treatments for breast cancer, specifically hormonal therapy, accelerate bone loss (BL) among breast cancer survivors, leading to osteoporosis and an increase in fracture risk. Tai Chi Chuan (TCC) is a moderate form of weight-bearing exercise, equivalent to walking, and it has been shown to improve aerobic capacity and strength among breast cancer survivors and might also be effective in slowing bone loss in breast cancer survivors. This pilot study compared the influence of TCC with that of standard support therapy (ST; exercise control) on BL biomarkers among breast cancer survivors. PATIENTS AND METHODS: Randomly assigned breast cancer survivors (N = 16; median age, 53 years; < 30 months after treatment) completed 12 weeks (3 times per week, 60 minutes per session) of TCC or ST. Serum levels of N-telopeptides of type I collagen (NTx), a marker of bone resorption, and bone-specific alkaline phosphatase (BSAP), a marker of bone formation, were determined according to enzyme-linked immunosorbent assay at baseline and after the intervention. RESULTS: Using analysis of covariance, survivors in the TCC group experienced a greater increase in levels of bone formation (BSAP [microg/L]: before, 8.3; after, 10.2; change, 1.9 microg/L and 22.4%), compared with survivors in ST (BSAP [microg/L]: before, 7.6; after, 8.1; change, 0.5 microg/L [6.3%]). Survivors in the TCC group also experienced a significant decrease in bone resorption (NTx [nanomoles bone collagen equivalent; nmBCE]: before, 17.6; after, 11.1; change, -6.5 nmBCE; -36.9%), whereas women in the ST group did not (NTx [nmBCE]: before, 20.8; after, 18.8; change, -2.0 nmBCE; -9.6%). CONCLUSION: This pilot study suggests that weight-bearing exercise exerts positive effects on BL, through increased bone formation and decreased bone resorption. Further examinations of the influence of TCC on bone health are warranted.

Models that explain preventive behaviors, such as colorectal cancer (CRC) screening, do not account for social and cultural factors relevant to African Americans. This exploratory study examined the relationship between socio-cultural factors (e.g., traditional acculturative strategy, group-based medical mistrust, physician ethnicity, and group-level perceptions of susceptibility) and perceived benefits, perceived barriers, and CRC screening intentions among African Americans (N = 198; Age: M = 59.7, SD = 9.9; 65% female; 44% household income $50,000+). Hierarchical multiple regression was used to test the following models with perceived benefits, perceived barriers, and screening intentions as the outcomes: (a) traditional acculturative strategy x medical mistrust; (b) physician's ethnicity x medical mistrust; (c) group susceptibility x medical mistrust; and (d) group susceptibility x traditional acculturative strategy. Results revealed that perceiving high group susceptibility while being both more culturally traditional and less mistrustful was associated with more perception of screening benefits. Greater intention to be screened was associated with perceiving high group susceptibility while having a more traditional cultural orientation and low levels of mistrust in those with African American physicians. These results suggest that it may be beneficial to include these social and cultural factors in behavioral interventions to increase CRC screening among African Americans.

PURPOSE: Sleep disruption is prevalent in patients with cancer and survivors, but the prevalence of insomnia, a distressing sleep disorder, in these populations has yet to be determined in large-scale studies. PATIENTS AND METHODS: A total of 823 patients with cancer receiving chemotherapy (mean age, 58 years; 597 female patients) reported on sleep difficulties in a prospective study. RESULTS: During day 7 of cycle 1 of chemotherapy, 36.6% (n = 301) of the patients with cancer reported insomnia symptoms, and 43% (n = 362) met the diagnostic criteria for insomnia syndrome. Patients with cancer younger than 58 years were significantly more likely to experience either symptoms of insomnia or insomnia syndrome (chi(2) = 13.6; P = .0002). Patients with breast cancer had the highest number of overall insomnia complaints. A significant positive association was found between symptoms of insomnia during cycles 1 and 2 of chemotherapy (phi = .62, P < .0001), showing persistence of insomnia during the first two cycles of chemotherapy. Sixty percent of the patient sample reported that their insomnia symptoms remained unchanged from cycle 1 to cycle 2. Those with insomnia complaints had significantly more depression and fatigue than good sleepers (all P < .0001). CONCLUSION: The proportions of patients with cancer in this sample reporting symptoms of insomnia and meeting diagnostic criteria for insomnia syndrome during chemotherapy are approximately three times higher than the proportions reported in the general population. Insomnia complaints persist throughout the second chemotherapy cycle for the majority of patients with cancer in this study. Insomnia is prevalent, underrecognized, undermanaged, and understudied among patients with cancer receiving chemotherapy.

BACKGROUND: The majority of recent, well-designed studies have shown that long-term cigarette smoking increases colorectal cancer risk, but older studies with shorter durations of exposure often found no association. This study aimed to examine colorectal cancer risk by smoking exposure using data collected in the late-1950s and early-1960s. METHODS: This case-control study examined colorectal cancer risk by lifetime smoking history. There were 1365 patients who visited Roswell Park Cancer Institute (RPCI) between 1957 and 1965 diagnosed with primary, incident colorectal cancers that were matched to 4096 malignancy-free controls on gender and age. Odds ratios were calculated using separate logistic regression models for each smoking exposure, while controlling for other tobacco use, county of residence, race, age, gender, and body mass index (BMI). RESULTS: The adjusted OR for individuals who reported their greatest level of smoking to be more than 1 pack/day was 0.87 (95% CI=0.67-1.15). Among those who smoked 42 or more years, the adjusted OR was 0.89 (95% CI=0.68-1.15) compared to those who never smoked. For individuals who smoked more than 45 pack-years, the OR was 0.92 (95% CI=0.72-1.19). The results did not differ significantly by gender, although men had considerably greater exposure compared to women. Results also did not differ by colorectal sub-site. CONCLUSION: No association was found between long-term cigarette smoking and colorectal cancer risk. These results are in accord with studies that followed cohorts throughout the 1950s and 1960s. Methodological limitations, such as missing data on covariates and the higher incidence of smoking-related illness in a hospital setting, may have contributed to the null results found in this study. Prolonged population exposure to cigarettes and perhaps a changing product may explain why more recent studies have reported a positive association between smoking and colorectal cancer.

Previous studies have shown that acupressure bands can reduce chemotherapy-related nausea. Patients' expectations of efficacy account for part of this outcome. We conducted a three-arm randomized clinical trial to investigate the effectiveness of acupressure bands in controlling radiation therapy-induced nausea and to test whether an informational manipulation designed to increase expectation of efficacy would enhance the effectiveness of the acupressure bands. Patients who experienced nausea at prior treatments were randomized to either standard care (Arm 1, n=29) or standard care plus acupressure bands with either neutral (Arm 2, n=30) or positive (Arm 3, n=29) information regarding the efficacy of the bands. Patients reported nausea for two days prior to randomization (baseline) and for five days following using a seven-point semantic rating scale (1=not nauseated to 7=extremely nauseated). Patients in Arms 2 and 3 combined reported greater reduction in average nausea than patients in Arm 1 (P=0.01; mean(bands)=0.70, mean(no bands)=0.10). This equates to a 23.8% decrease in nausea in the band groups compared to a 4.8% decrease in the control group, a 19% difference. The informational manipulation failed to alter efficacy expectations and there was no statistically significant difference in nausea between patients in Arms 2 and 3. Acupressure bands are an effective, low-cost, nonintrusive, well-accepted, and safe adjunct to standard antiemetic medication. An attempt to boost the efficacy of the acupressure bands by providing positive information was not successful.

Cancer-related fatigue is the most common side effect reported by cancer patients during and after treatment. Cancer-related fatigue significantly interferes with a patient's ability to perform activities of daily living and maintain functional independence and quality of life. Cancer-related fatigue can also interfere with a patient's ability to complete treatments. The purpose of this article is to provide an overview of cancer-related fatigue, its pathopsychophysiology, and the role of exercise in the management of this side effect.
RESUMO
Religion and spirituality are resources regularly used by patients with cancer coping with diagnosis and treatment, yet there is little research that examines these factors separately. This study investigated the relationships between religious practice and spirituality and quality of life (QoL) and stress in survivors of breast cancer. The sample included 130 women assessed 2 years following diagnosis. Using hierarchical multiple regression analysis, the authors found that spiritual well-being was significantly associated with QoL and traumatic stress, whereas religious practice was not significantly associated with these variables. The results suggest that it may be helpful for clinicians to address spirituality, in particular with survivors of breast cancer.
RESUMO
Meaning in life is a multi-faceted construct that has been conceptualized in diverse ways. It refers broadly to the value and purpose of life, important life goals, and for some, spirituality. We developed a measure of meaning in life derived from this conceptualization and designed to be a synthesis of relevant theoretical and empirical traditions. Two samples, all cancer patients, provided data for scale development and psychometric study. From exploratory and confirmatory factor analyses the Meaning in Life Scale (MiLS) emerged, and includes four aspects: Harmony and Peace, Life Perspective, Purpose and Goals, Confusion and Lessened Meaning, and Benefits of Spirituality. Supporting data for reliability (internal consistency, test-retest) and construct validity (convergent, discriminant, individual differences) are provided. The MiLS offers a theoretically based and psychometrically sound assessment of meaning in life suitable for use with cancer patients.
