<h4>Purpose</h4>Few studies have examined lifestyle factors and quality of life (QOL) in cancer survivors compared to a cancer-free group. Compared to active cancer-free women, we examined the association between physical inactivity and QOL in elderly cancer survivors and similar-aged women without cancer.<h4>Methods</h4>Participants included 1776 cancer survivors and 12,599 cancer-free women enrolled in the Iowa Women's Health Study in 1986 who completed the SF36 QOL assessment in 2004 (ages 73 ...[more]

Project description:PurposeThe impact of lymphedema or related arm symptoms on health-related quality of life (HRQOL) in breast cancer (BrCa) survivors has not been examined using a large population-based cohort.Patients and methodsThe Iowa Women's Health Study (IWHS) collected self-report data for lymphedema, arm symptoms, and HRQOL (Medical Outcomes Study Short Form-36) in 2004 and data for cancer diagnosis, treatment, and behavioral and health characteristics between 1986 and 2003. We studied 1,287 women, age 55 to 69 years at baseline, who developed unilateral BrCa. We used cross-sectional analyses to describe the prevalence of lymphedema and arm symptoms and multivariate-adjusted generalized linear models to compare HRQOL (physical functioning, bodily pain, general health, physical and emotional role limitations, vitality, social functioning, and mental health) between the following three survivor groups: women with lymphedema (n = 104), women with arm symptoms without diagnosed lymphedema (n = 475), and women without lymphedema or arm symptoms (n = 708).ResultsThe mean (+/- SE) time between BrCa diagnosis and lymphedema survey was 8.1 +/- 0.2 years. Of BrCa survivors, 8.1% self-reported diagnosed lymphedema, and 37.2% self-reported arm symptoms. Knowledge of lymphedema was low among survivors without diagnosed lymphedema (n = 1,183). After multivariate adjustment, women with diagnosed lymphedema or arm symptoms without diagnosed lymphedema had lower physical and mental HRQOL compared with women without lymphedema or arm symptoms. Effect sizes were mild to moderate. There was a dose-response relation between number of arm symptoms and lower HRQOL.ConclusionIn the IWHS, HRQOL was lower for BrCa survivors with diagnosed lymphedema and for those with arm symptoms without diagnosed lymphedema. Clinical trials are needed to determine what interventions can improve lymphedema and impact HRQOL for BrCa survivors.

Project description:BackgroundTo the authors' knowledge, few studies to date have examined associations between moderate to vigorous physical activity (MVPA) and sitting time with quality of life in cancer survivors compared with a cancer-free group. The current study examined differences in global mental health (GMH) and global physical health (GPH) across levels of MVPA and sitting among cancer survivors and cancer-free participants.MethodsCancer Prevention Study II participants (59.9% of whom were female with an age of 77.8 ± 5.8 years) were grouped as: 1) survivors who were 1 to 5 years after diagnosis (3718 participants); 2) survivors who were 6 to 10 years after diagnosis (4248 participants); and 3) cancer-free participants (ie, no history of cancer; 69,860 participants). In 2009, participants completed MVPA, sitting, and Patient-Reported Outcomes Measurement Information System GMH/GPH surveys. Mean differences in GMH and GPH T scores across MVPA (none, 0 to <7.5, 7.5 to <15, 15 to <22.5, and ≥22.5 metabolic equivalent [MET]-hours/week) and sitting (0 to <3, 3 to <6, and ≥6 hours/day) were assessed using multivariate generalized linear models.ResultsThe mean GMH and GPH scores were statistically significantly higher in cancer-free participants compared with cancer survivor groups, although the differences were not clinically meaningful (mean difference of 0.52 for GMH and 0.88 for GPH). More MVPA was associated with higher GMH and GPH scores for all 3 groups (P for trend <.001), and differences between the least and most active participants were found to be clinically meaningful (mean differences of ≥4.34 for GMH and ≥6.39 for GPH). Similarly, a lower duration of sitting was associated with higher GMH and GPH scores for all groups (P for trend <.001), with clinically meaningful differences observed between the least and most sedentary participants (mean differences of ≥2.74 for GMH and ≥3.75 for GPH).ConclusionsThe findings of the current study provide evidence of the importance of increased MVPA and decreased sitting for improved health in older adults with or without a prior cancer diagnosis.

Project description:ImportanceThe number of cancer survivors living in the US is projected to be 26.1 million by 2040. Cancer survivors may be at increased risk of bone fractures, but research is limited in several important ways.ObjectiveTo investigate the associations of cancer diagnoses, including time since diagnosis and stage at diagnosis, with risks of pelvic, radial, and vertebral fractures (separately and combined) among older cancer survivors and compared with fracture risk among older adults without a history of cancer. Secondarily, to examine differences in risk of fracture stratified by modifiable behaviors, treatment, and cancer type.Design, setting, and participantsThis longitudinal cohort study used data from 92 431 older adults in the US Cancer Prevention Study II Nutrition Cohort linked with 1999 to 2017 Medicare claims. Data were analyzed from July 15, 2021, to May 3, 2022.ExposuresCancer history, time since cancer diagnosis, and stage at cancer diagnosis.Main outcomes and measuresHazard ratios (HRs) and 95% CIs for the risk of pelvic, radial, vertebral, and total frailty-related fractures were estimated using multivariate Cox proportional hazards regression. Stratification was used for secondary aims.ResultsAmong 92 431 participants (mean [SD] age, was 69.4 [6.0] years, 51 820 [56%] women, and 90 458 [97.9%] White], 12 943 participants experienced a frailty-related bone fracture. Compared with participants without a history of cancer, cancer survivors who were diagnosed 1 to less than 5 years earlier with advanced stage cancer had higher risk of fracture (HR, 2.12; 95% CI, 1.75-2.58). The higher fracture risk in cancer survivors with recent advanced stage diagnosis (vs no cancer) was driven largely by vertebral (HR, 2.46; 95% CI, 1.93-3.13) and pelvic (HR, 2.46; 95% CI, 1.84-3.29) fracture sites. Compared with cancer survivors who did not receive chemotherapy, survivors who received chemotherapy were more likely to have a fracture; this association was stronger within 5 years of diagnosis (HR, 1.31; 95% CI, 1.09-1.57) than 5 or more years after diagnosis (HR, 1.22; 95% CI, 0.99-1.51). Although the HR for risk of fracture was lower among physically active cancer survivors 5 or more years after diagnosis (HR, 0.76; 95% CI, 0.54-1.07), this result was not statistically significant, whereas current smoking was significantly associated with higher risk of fracture (HR, 2.27; 95% CI, 1.55-3.33).Conclusions and relevanceFindings from this cohort study suggest that older adults with a history of cancer may benefit from clinical guidance on prevention of frailty-related fractures. If study findings are replicated, fracture prevention programs for survivors might include referrals for physical activity with cancer exercise professionals and smoking cessation programs.

Project description:BackgroundDescribing correlates of physical activity (PA) and sedentary behavior (SB) among postmenopausal cancer survivors can help identify risk profiles and can be used to support development of targeted interventions to improve PA and reduce SB in this population.ObjectiveTo describe PA/SB and identify correlates of PA/SB among cancer and cancer-free post-menopausal women.MethodsWomen from the Women's Health Study (N = 16,629) and Women's Health Initiative/Objective Physical Activity and Cardiovascular Health Study (N = 6,079) were asked to wear an accelerometer on the hip for 7 days. Multiple mixed-effects linear regression models were used to identify sociodemographic-, health-, and chronic condition-related correlates (independent variables) associated with PA and SB (dependent variables) among women with (n = 2,554) and without (n = 20,154) a history of cancer. All correlates were mutually adjusted for each other.ResultsIn unadjusted analyses, women with a history of cancer took fewer mean daily steps (4,572 (standard deviation 2557) vs 5,029 (2679) steps/day) and had lower mean moderate-to-vigorous PA (74.9 (45.0) vs. 81.6 (46.7) minutes/day) than cancer-free women. In adjusted analyses, for cancer and cancer-free women, age, diabetes, overweight, and obesity were inversely associated with all metrics of PA (average vector magnitude, time in moderate-to-vigorous PA, step volume, time at ≥40 steps/minutes, and peak 30-minute step cadence). In unadjusted analyses, mean SB was similar for those with and without cancer (529.7 (98.1) vs. 521.7 (101.2) minutes/day). In adjusted analyses, for cancer and cancer-free women, age, diabetes, cardiovascular disease, current smoking, overweight, and obesity were positive correlates of SB, while Black or Hispanic race/ethnicity, weekly/daily alcohol intake, and excellent/very good/good self-rated health were inverse correlates of SB.ConclusionSeveral sociodemographic, health, and chronic conditions were correlates of PA/SB for postmenopausal women with and without cancer. Future studies should examine longitudinal relationships to gain insight into potential determinants of PA/SB.

Project description:BackgroundMany studies have reported a positive association between diabetes and kidney cancer. However, it is unclear whether diabetes is a risk factor for kidney cancer independent of other risk factors, such as obesity and hypertension. We comprehensively examined the association of diabetes and its duration with incident kidney cancer in the prospective cohort Iowa Women's Health Study (1986-2011).MethodsDiabetes status was self-reported at baseline (1986) and on five follow-up questionnaires. Cox proportional hazards regression was used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for the associations of baseline and time-dependent diabetes with the risk of incident kidney cancer.ResultsDuring the 25 years of follow-up, 245 cases of kidney cancer occurred among 36,975 post-menopausal women. In an age-adjusted model, there was a significant association between time-dependent diabetes and the risk of kidney cancer [HR (95% CI) = 1.76 (1.26, 1.45)]; the association was attenuated after multivariable adjustment for age, body mass index (BMI), waist-to-hip ratio (WHR), hypertension, physical activity, diuretic use, pack-years of smoking, alcohol intake, and total caloric intake [HR = 1.35 (0.94, 1.94)]. However, among non-obese women or women with a waist circumference less than 34.6 in., diabetes was significantly associated with kidney cancer risk: for time-dependent diabetes, HRs (95% CIs) were 1.82 (1.10, 3.00) among those with BMI < 30 kg/m2 and 2.18 (1.08, 4.38) among those with a waist circumference <34.6 in..ConclusionsOur results suggest that diabetes is associated with kidney cancer risk among non-obese post-menopausal women.

Project description:The role of the innate immune response in colorectal cancer is understudied. We examined the survival of colorectal cancer patients in relation to eosinophils, innate immune cells, infiltrating the tumor. Tissue microarrays were constructed from paraffin-embedded tumor tissues collected between 1986 and 2002 from 441 post-menopausal women diagnosed with colorectal cancer in the Iowa Women's Health Study. Tissue microarrays were stained with an eosinophil peroxidase antibody. Eosinophils in epithelial and stromal tissues within the tumor (called epithelial and stromal eosinophils, hereafter) were counted and scored into three and four categories, respectively. In addition, the degree of eosinophil degranulation (across epithelial and stromal tissues combined) was quantified and similarly categorized. We used Cox regression to estimate the hazard ratios and 95% confidence interval for all-cause and colorectal cancer death during 5-year follow-up after diagnosis and during follow-up through 2011 ('total follow-up'). The hazard ratios associated with eosinophil scores were adjusted for age of diagnosis, SEER (Surveillance, Epidemiology, and End Results) stage, tumor grade, body mass, and smoking history. High tumor stromal eosinophil score was inversely correlated with age and stage, and was associated with a decreased risk for all-cause and colorectal cancer death: hazard ratios (95% confidence intervals) were 0.61 (0.36-1.02; P-trend=0.02) and 0.48 (0.24-0.93; P-trend=0.01), respectively, during the 5-year follow-up for the highest vs lowest category. The inverse associations also existed for total follow-up for all-cause and colorectal cancer death for the highest vs lowest stromal eosinophil score: hazard ratios (95% confidence intervals) were 0.72 (0.48-1.08; P-trend=0.04) and 0.61 (0.34-1.12; P-trend=0.04), respectively. Further adjustment for treatment, comorbidities, additional lifestyle factors, tumor location, or molecular markers did not markedly change the associations, while adjustment for cytotoxic T cells slightly attenuated all associations. The infiltration of tumors with eosinophils, especially in stromal tissue, may be an important prognostic factor in colorectal cancer.

Project description:PurposeReduced physical activity in many chronic diseases is consistently associated with increased morbidity. Little is known about physical activity in sarcoidosis. The aim of this study was to objectively assess physical activity in patients with pulmonary sarcoidosis and investigate its relationship with lung function, exercise capacity, symptom burden, and health status.MethodsPhysical activity was assessed over one week in 15 patients with pulmonary sarcoidosis and 14 age-matched healthy controls with a tri-axial accelerometer (ActivPal™) and the International Physical Activity Questionnaire (IPAQ). All participants underwent pulmonary function tests, 6-min walk test (6MWT) and completed the Fatigue Assessment Scale (FAS), Medical Research Council (MRC) Dyspnoea Scale and the King's Sarcoidosis Questionnaire (KSQ).ResultsPatients with sarcoidosis had significantly lower daily step counts than healthy controls; mean (SD) 5624 (1875) versus 10,429 (2942) steps (p?<?0.01) and a trend towards fewer sit-to-stand transitions each day (p?=?0.095). Only two patients (13%) self-reported undertaking vigorous physical activity (IPAQ) compared to half of healthy individuals (p?<?0.01). Daily step count was significantly associated with 6MWT distance in sarcoidosis (r?=?0.634, p?=?0.01), but not with forced vital capacity (r?=?0.290), fatigue (r?=?0.041), dyspnoea (r?=?-0.466) or KSQ health status (r?=?0.099-0.484). Time spent upright was associated with fatigue (r?=?-0.630, p?=?0.012) and health status (KSQ Lung scores r?=?0.524, p?=?0.045), and there was a significant correlation between the number of sit-to-stand transitions and MRC dyspnoea score (r?=?-0.527, p?=?0.044).ConclusionPhysical activity is significantly reduced in sarcoidosis and is associated with reduced functional exercise capacity (6MWD). Fatigue, exertional symptoms and health status were more closely associated with time spent upright and the number of bouts of physical activity, as compared to step counts. Further studies are warranted to identify the factors that determine different physical activity profiles in sarcoidosis.

Project description:PurposeFew studies have evaluated the chemopreventive effect of aspirin on the cancer risk in elderly women. We examined associations between frequency, dose, and duration of aspirin use with incidence of 719 aspirin-sensitive cancers (cancers of colon, pancreas, breast, and ovaries) in the Iowa Women's Health Study (IWHS), a prospective cohort of women over 70 years old.MethodsAspirin frequency, dose, and duration were self-reported in the 2004 IWHS questionnaire. Women were followed-up to 2011. Cancer cases were ascertained by linkage to the Iowa State Health Registry. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95 % confidence intervals (CI).ResultsAmong the 14,386 women, 30 % were nonusers of aspirin; 34 % used low-dose aspirin, and 36 % used regular- or high-dose aspirin. Compared with nonuse of aspirin, the HRs (95 % CI) for incidence of aspirin-sensitive cancers were 0.87 (0.72-1.06) for regular to high doses of aspirin use, 0.95 (0.80-1.13) for aspirin use 6+ times per week, and 0.93 (0.74-1.17) for aspirin use for 10+ years. For cumulative aspirin use, HR (95 % CI) was 0.87 (0.70-1.09) for >60,000 mg of aspirin per year and 0.95 (0.75-1.21) for >280,000 mg of aspirin in their lifetime, versus nonuse of aspirin. Results were similar for the all-cause cancer death as an endpoint, with a significant inverse association observed between lifetime aspirin dose and cancer mortality [<95,000 mg vs nonuser HR 0.76 (0.61-0.95)].ConclusionsThese findings suggest that aspirin use may prevent incident breast, colon, pancreatic, and ovarian cancer in elderly women.

Project description:Gait speed is associated with multiple adverse outcomes of aging. We hypothesized that physical inactivity would be prospectively inversely associated with gait speed independently of white matter hyperintensity volume and silent brain infarcts on MRI.Participants in the Northern Manhattan Study MRI sub-study had physical activity assessed when they were enrolled into the study. A mean of 5 years after the MRI, participants had gait speed measured via a timed 5-meter walk test. Physical inactivity was defined as reporting no leisure-time physical activity. Multi-variable logistic and quantile regression was performed to examine the associations between physical inactivity and future gait speed adjusted for confounders.Among 711 participants with MRI and gait speed measures (62% women, 71% Hispanic, mean age 74.1 ± 8.4), the mean gait speed was 1.02 ± 0.26 m/s. Physical inactivity was associated with a greater odds of gait speed in the lowest quartile (<0.85 m/s, adjusted OR 1.90, 95% CI 1.17-3.08), and in quantile regression with 0.06 m/s slower gait speed at the lowest 20 percentile (p = 0.005).Physical inactivity is associated with slower gait speed independently of osteoarthritis, grip strength, and subclinical ischemic brain injury. Modifying sedentary behavior poses a target for interventions aimed at reducing decline in mobility.

Project description:BackgroundPhysical inactivity is one of the modifiable risk factors for hippocampal atrophy and Alzheimer's disease. We investigated the relationship between physical activity, hippocampal atrophy, and memory using structural equation modeling (SEM).Materials and methodsWe examined 213 community-dwelling elderly subjects (99 men and 114 women with a mean age of 68.9 years) without dementia or clinically apparent depression. All participants underwent Mini-Mental State Examination (MMSE) and Rivermead Behavioral Memory Test (RBMT). Physical activities were assessed with a structured questionnaire. We evaluated the degree of hippocampal atrophy (z-score-referred to as ZAdvance hereafter), using a free software program-the voxel-based specific regional analysis system for Alzheimer's disease (VSRAD) based on statistical parametric mapping 8 plus Diffeomorphic Anatomical Registration Through an Exponentiated Lie algebra.ResultsRoutine magnetic resonance imaging findings were as follows: silent brain infarction, n = 24 (11.3%); deep white matter lesions, n = 72 (33.8%); periventricular hyperintensities, n = 35 (16.4%); and cerebral microbleeds, n = 14 (6.6%). Path analysis based on SEM indicated that the direct paths from leisure-time activity to hippocampal atrophy (β = -.18, p < .01) and from hippocampal atrophy to memory dysfunction (RBMT) (β = -.20, p < .01) were significant. Direct paths from "hippocampus" gray matter volume to RBMT and MMSE were highly significant, while direct paths from "whole brain" gray matter volume to RBMT and MMSE were not significant. The presented SEM model fit the data reasonably well.ConclusionBased on the present SEM analysis, we found that hippocampal atrophy was associated with age and leisure-time physical inactivity, and hippocampal atrophy appeared to cause memory dysfunction, although we are unable to infer a causal or temporal association between hippocampal atrophy and memory dysfunction from the present observational study.
