Health behaviors (HB) and geriatric assessment (GA) in older women with breast cancer (BC).

Abstract

9543 Background: Physical inactivity (PI), alcohol (A) and tobacco (T) abuse are associated with poor health outcomes in older adults, however, little is known about the prevalence of these HB and their associations with GA domains in older cancer patients (pts). This study explores the relationship between HB and GA in older BC pts. Methods: Between 03/2010-01/2013, 111 pts ≥65 yrs completed a predominantly self-administered GA (Hurria et al. Cancer 2005) comprising measures of comorbidity, polypharmacy, cognitive, functional, psychosocial and nutritional status as well as a nine-item HB questionnaire based on the 2006/7 National Health Interview Survey ( www.cdc.gov/nchs/nhis.htm ) assessing PI, A and T use. Fisher’s Exact and Wilcoxon Rank sum test were used to evaluate associations with GA measures. Results: Median age was 72 (range 65-94). Most pts were white (89%), married (61%), retired (86%) and at least high school graduates (96%). 51% never smoked while 45% were former and 4% current smokers. Former/current smokers were more likely than never smokers to have slower gait speeds (Timed “up and go” >14 second; 32 vs 14%; p=.04) and took more daily prescription medications (mean 5 vs. 4; p=.04). 52% of pts consumed at least one alcoholic drink per week (median 3.5). Modest alcohol consumption was associated with less activity of daily living (ADL) impairment (p=.03), lower mean BMI (29 vs. 26 kg/m2 p=.03) and greater non-prescription medication use (p=.04). 48% never performed vigorous activity and these pts were more likely than those exercising to have one or more functionally impairing comorbidities (p=.03); mainly arthritis. PI correlated with more impairment in both ADL (p<.0001) and instrumental ADL (p=.004). HB were not associated with demographic factors, treatment phase, weight loss, falls, sensory impairment, social activity, anxiety or depression in this dataset. Conclusions: PI, T and A use were common in this cohort of older BC pts and were associated with significant impairments in several GA domains. These findings reinforce the need for interventions to improve HB in older BC pts. Support: Breast Cancer Research Foundation, New York, NY and Lineberger Comprehensive Cancer Center, Chapel Hill, NC.
