Objectively-measured physical activity patterns and longitudinal weight category status in a rural setting

Objectives To investigate the relationship between longitudinal weight-change and objectively-measured physical activity (PA) in a rural African setting in 143 adults (≥ 30 years), using data from two cross-sectional surveys, separated by approximately 10 years. Participants were categorised into three weight-change groups (Weight-loss: ≥ 25 kg m−2→ < 25 kg m−2; Weight-gain: < 25 kg m−2→ ≥ 25 kg m−2; Weight-stability: remained < 25 kg m−2 or ≥ 25 kg m−2). Daily ambulation and activity energy expenditure (AEE), measured in the 2005–2007 health survey, was examined across the weight-change groups. Using the daily AEE data, the proportion of those in the weight-change groups, meeting or not meeting two PA guidelines (150- and 420 min week−1), was examined.
