Objectively assessed physical activity levels in Spanish cancer survivors

To objectively assess physical activity (PA) levels in a cohort of Spanish cancer survivors.

Descriptive, cross-sectional.

The Hospital Universitario de Fuenlabrada and two healthcare centers in Madrid, Spain.

204 cancer survivors and 115 adults with no history of cancer.

Participants wore a triaxial accelerometer for seven or more consecutive days to assess PA levels. Body mass index (BMI), indirect indicators of adiposity (waist circumference, waist-to-hip ratio), and cardiorespiratory fitness also were determined.

Light, moderate, vigorous, and total PA (sum of the former).

Most (94%) of the cancer survivors met international recommendations for moderate PA, but very few (3%) fulfilled those (75 minutes or more per week) for vigorous PA. Except for lower total (minute per day, p=0.048) and vigorous PA levels (p<0.001 for both minute per day and minute per week) recorded in the cancer survivors group, no between-group differences were detected (p>0.05). A high percentage of the survivors (33%) were obese (BMI greater than 30 kg/m2), and many also showed poor cardiorespiratory fitness (45% were below the 8 metabolic equivalent threshold).

Although cancer survivors overall met international PA recommendations for a healthy lifestyle, their BMI and cardiorespiratory profiles were not within the healthy range.

Cancer survivors need to be informed about healthy lifestyle habits and should be regularly monitored.
