Efficacy of a Multiple Health Behavior Change Intervention on Women’s Health Outcomes

Abstract

Objective: Examine the efficacy of a 60 day autophagy-activating multiple health behavior 
change (MHBC) intervention that targets exercise, diet, sleep, and skincare on women’s health 
outcomes.
 Design: Using a single-arm intervention, 34 women (age range=30-55 years) completed both 
subjective self-report assessments (i.e., health-related quality of life, sleep quality, body satis
faction, and skin satisfaction) and objective assessments of body composition (i.e., BOD POD), 
blood pressure, heart rate, and skin health (i.e., dermatologist skin ratings) at day 0, day 30, 
and day 60. 
Results: We found significant improvements from day 0 to day 30 to day 60 for the objec
tive assessments of body composition (F=23.48, p<.001) and wrinkles (F=57.72, p<.001); and 
the subjective assessments of body satisfaction (F=23.03, p<.001), skin satisfaction (F=20.29, 
p<.001), and overall health-related quality of life (HRQOL) (F=5.27, p<.01). We found signifi
cant improvements from day 0 to day 60 for the subjective assessment of sleep quality (F=5.90, 
p<.007) and the objective assessments of heart rate (F=3.70, p=0.04) and systolic blood pres
sure (F=2.41, p<0.01).
 Conclusion: A sixty day MHBC intervention improved women’s targeted health outcomes of 
body satisfaction, skin satisfaction, sleep quality, aspects of health-related quality of life, heart 
rate, systolic blood pressure, and body composition. A randomized controlled trial with long
term follow-up in a variety of populations is needed to further determine the efficacy of this 
MHBC intervention.
