Abstract
Background: Prostate cancer (PC) is the most commonly diagnosed cancer in American men with 1 in 8 men diagnosed in their lifetime. African American men have the highest rates of incidence and mortality for PC in the USA, due to a myriad of socio-biological factors. Fortunately, given advances in screening and treatment options the survival rate of PC is high with a 97% 5-year survival rate. However, PC treatments can cause muscle atrophy and reduced physical functioning and quality of life (QoL). Physical function and strength can serve as proxy measurements for cellular aging, longevity, and QoL. Handgrip is related to overall strength, upper limb function, bone mineral density, and mortality. Sit-to-stand measures leg strength and endurance and is used to evaluate fall risk. The 6-minute walk test (6MW) is used to assess aerobic capacity. Men Moving Forward (MMF) is one of the first community-based lifestyle programs developed with and for African American Prostate Cancer Survivors (AAPCS). This study examines objective and subjective physical function of MMF participants at baseline. Methods: MMF is a randomized, wait-list control trial with a 16-week group-based lifestyle intervention focused on physical activity, nutrition and QoL, led by local health coaches. Participants complete physical assessments and surveys at baseline, post-intervention and 12 months. Physical assessments consist of a blood draw, DXA scan, anthropometric measurements, handgrip strength, 30-second sit-to-stand, and 6MW (added with second cohort). Participants also answer surveys on their health and physical function. Pearson’s correlation was used to assess linear correlation between fitness measures and self-reported physical function. Results: At baseline, 100 AAPCS completed both the physical assessment and survey. Participants had a mean age of 65.8 ± 7.26 years, 49% were married/living with a partner, 47.6% were retired, and education levels varied. Top comorbidities include hypertension, obesity, diabetes, and hypercholesterolemia. Mean hand grip scores were 39.8 ± 7.5kg for right and 38.4 ± 7.7kg for left. Handgrip scores 28.2-44.0kg for men aged 64-69 are considered normal. Mean sit-to-stand (n=96) was 12.2 ± 4.3 reps in 30 seconds. Since 6MW was added later in the study, 68 men completed with a mean score of 0.42 ± 0.10 km. Normal ranges for men aged 65-69 is 15 reps for sit-to-stand and 0.572km for 6MW. 50% of participants rated their overall health as “good”, 21% as “very good”, and 20% as “fair” on a five-point Likert scale. PROMIS physical function measures had an average of 50.3 ± 7.3 for men at baseline. PROMIS physical function was weakly correlated with 6MW and sit-to-stand with r = 0.34, p-value=0.004 and r = 0.27, p- value=0.009, respectively. Conclusion: Data reflect the value of supporting AAPCS in lifestyle changes to improve physical function. Few efforts have addressed lifestyle among AAPCS, despite high prostate cancer burden. Future reports will examine the efficacy of MMF in improving physical function, overall health, and QoL.
