Association of Physical Activity and Sitting Time Balance Index with all-cause and cause-specific mortality among cancer survivors in the USA: a cohort study.

ABSTRACT:

Purpose

This study examined the relationship between Physical Activity and Sitting Time Balance Index (PASTBI) and mortality outcomes, including all-cause, cardiovascular diseases (CVD)-, and cancer-specific mortality, in a nationally representative cohort of US cancer survivors.

Methods

Data were derived from the National Health and Nutrition Examination Survey 2007-2018. The PASTBI was calculated using information from the Global Physical Activity Questionnaire, with mortality data obtained through linked databases. Cox proportional hazards models with survey sample weights were applied to estimate hazard ratios (HRs) for all-cause, CVD-related, and cancer-related mortality, adjusting for potential confounders.

Results

The analysis included 3334 cancer survivors, wi
