PMID 35794781WHAT IT FOUND
Insufficiently active African American women with obesity had very low physical activity, high blood pressure, and poor cardiorespiratory fitness.
Most met criteria for metabolic syndrome. These baseline findings describe a high-risk group but do not test whether an intervention improves these outcomes.
Key findings
01Participants performed only 2.1 minutes per day of moderate-to-vigorous physical activity in bouts of 10 minutes or longer, and 66.7% had no days with such a bout.
0267.2% of participants were classified as having metabolic syndrome, and 75% had stage 1 or stage 2 hypertension.
03Cardiorespiratory fitness was low, with a mean VO2 peak of 18.7 ml/kg/min, which is 41% lower than the normative reference value for this age group.

What it does not show
The study reports only baseline characteristics from a pilot trial, so it cannot determine if any intervention improved outcomes. The sample size is small (n=60) and homogeneous, limiting generalizability to other populations. Accelerometer data were collected using a wrist-worn device with cutpoints developed from healthy, normal-weight individuals, which may not accurately reflect physical activity in women with obesity. Exploratory correlations between physical activity and cardiometabolic risk factors were not statistically significant after adjusting for multiple comparisons.
Declared interests
The authors declare no conflicts of interest to disclose.
The easy way to misread this
Do not interpret the moderate correlations between physical activity and cardiometabolic risk as causal or clinically significant evidence. These associations were exploratory, lost statistical significance after adjustment for multiple testing, and the study did not test an intervention effect.
