OBJECTIVES: To examine 2 modifiable health behaviors-smoking and physical
activity-and their relationship to mortality among individuals with multiple
sclerosis (MS). DESIGN: Secondary analysis of Large Health Survey. SETTING: Data
were obtained from a linkage of the Veterans Affairs (VA) MS National Data
Repository, containing information on service provision to all individuals with
MS receiving health services within the U.S. Department of Veterans Affairs; the
VA 1999 Large Health Survey, containing information on smoking and physical
activity; and the VA Vital Status File. All-cause mortality was examined for the
15-year period from 1999 through 2013. PARTICIPANTS: Participants (N=2994) with
MS who completed the Large Health Survey containing information on smoking and
physical activity. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Survival.
RESULTS: There were 1500 deaths (50.1%) during the study period. Cox proportional
hazard analyses were conducted to examine the association between smoking and
physical activity and 15-year mortality. After adjusting for demographic factors,
physical functioning, mental health, and comorbid medical conditions, baseline
smoking was associated with greater mortality (hazard ratio [HR]=1.38; 95%
confidence interval [CI], 1.184-1.60). Higher levels of baseline physical
activity were associated with lower mortality (activity 1-2 times/wk: HR=.64; 95%
CI, .518-.798; activity >/=3 times/wk: HR=.53; 95% CI, .388-.715). CONCLUSIONS:
Results suggest that modifiable health behaviors represent a promising
opportunity for intervention to improve the lives of individuals with MS.
