A cross-sectional study in Australia suggested that sitting-reduction strategies targeting increased standing, stepping, or both, may benefit cardio-metabolic health. Participants in 2011/12 wore a posture-based monitor (36–80 years, mean 57.9, 57% women; n = 698 with data). Associations of reallocating daily time from sitting/lying (sitting) to standing and stepping with cardio-metabolic risk biomarkers were analyzed. Adjusted for relevant confounders, sitting-to-standing reallocations were only significantly associated with approximately 2% lower fasting plasma glucose, 11% lower triglycerides, 6% lower total/HDL-cholesterol ratio, and 0.06 mmol/L higher HDL-cholesterol per 2 h/day. Sitting-to-stepping reallocations were only significantly associated with approximately 11% lower BMI, 7.5 cm lower waist circumference, 11% lower 2-h plasma glucose, 14% lower triglycerides, and 0.10 mmol/L higher HDL-cholesterol per 2 h/ day, while standing-to-stepping reallocations were only significantly associated with ∼10% lower BMI, 7 cm lower waist circumference, and 11% lower 2-h plasma glucose. High levels of sedentary time (sitting) have been linked detrimentally with cardiovascular disease, diabetes, and premature mortality.
