Adherence
In older adults, a higher percentage of time spent in sedentary behavior and fewer breaks in sedentary time are associated with a significantly greater likelihood of metabolic syndrome, independent of moderate-to-vigorous physical activity levels.
If you are over 60, simply exercising for an hour a day may not be enough to protect your metabolic health if you sit for the rest of the day. To lower your risk of metabolic syndrome, focus on reducing your total sitting time and, crucially, breaking up long periods of sitting with brief movements or standing up frequently throughout the day.
A higher percentage of time sedentary and fewer sedentary breaks were associated with a significantly greater likelihood of metabolic syndrome after adjustment for age, sex, ethnicity, education, alcohol consumption, smoking, BMI, diabetes, heart disease, and physical activity.
Why this rating
Large, nationally representative sample (NHANES), objective measurement via accelerometry, and rigorous adjustment for confounders, though the cross-sectional design limits causal inference.
