Title:
THE EFFECT OF WALKING on HEALTH OUTCOMES in SERIOUS MENTAL ILLNESS
Abstract:
Purpose: The purpose of this study is to determine the effect of walking on health outcomes in individuals with Serious Mental Illness (SMI). Background: Individuals with SMI are experiencing an epidemic of obesity with rates higher than those in the general population. Comorbid conditions resulting from obesity are widespread in individuals with SMI; sedentary lifestyles and the use of antipsychotic medications increase the risk of diabetes and cardiovascular diseases, shortening life span and reducing quality of life. Walking has been lauded as an effective form of physical activity (PA) for individuals with SMI as it is safe, effective, and feasible for this population. PA has been shown to exert positive effects on health outcomes of weight, Body Mass Index (BMI), blood pressure, glucose, and lipids, reducing the risk of complications resulting from comorbid conditions. Methods: This is a pilot study of a pedometer-based exercise program for patients with SMI. A randomized, two-group, experimental design with repeated measures was used. Subjects in the treatment group were educated to walk at least 30 minutes a day and received a weekly phone call. Subjects in the control group received written material on walking. Data was collected at baseline, 8 weeks, and 12 weeks. We analyzed 17 subjectsÕ health outcomes including weight, BMI, waist circumference, blood pressure, lipid panel, and fasting blood glucose measured at baseline and 8 weeks. Descriptive statistics, Wilcoxon Signed Rank test, and Mann-Whitney test were used in data analysis. Results: Among the 17 subjects, 58.8% were male (n=10) and 41.2% were female (n=7). The mean age was 44.35 years (SD=7.77) and 11 (64.7%) were African American. 9 subjects were assigned to the pedometer-based exercise group and 8 subjects were assigned to a control group. Six subjects dropped out of the study. Although there was no statistical significance in health outcomes between groups (Ps>0.05) and between baseline and 8 weeks (Ps>0.05), subjects in the treatment group had a numeric decrease in systolic (7%) and diastolic blood pressure (8%) between baseline and 8 weeks. Subjects in the control group also had a decrease in systolic (4.5%) and diastolic (6%) blood pressure.Implications: The results indicate subjects with SMI may benefit from PA even though the study did not display a statistically significant decrease in health outcomes. This pilot study was perhaps not long enough to showcase the decrease in weight that can result from an exercise program, and the small sample size and large drop out rate could also be factors. Blood pressure exerts positive effects on cardiovascular functioning and so it is important to note the decrease in blood pressure for the groups resultant of the sensitivity of the measurement method. The effects of improved health outcomes through walking in individuals with SMI as well as effects on length and quality of life are well documented, and the importance of further study in this area is great.
