Sarcopenic obesity, the combination of excess body fat and inadequate muscle mass, has been getting more attention from researchers lately, but good population-level data on who actually has it has been surprisingly hard to come by. A new study out of Taiwan, using the new 2025 Asia-Oceania definition, put numbers behind the condition in older Taiwanese adults.[1]
Researchers tracked 1,048 adults aged 65 and older in the Taichung Community Health Study for Elders, measuring body composition with DXA/BIA scans alongside waist circumference and physical function. At baseline, 2.0% of participants met the criteria for sarcopenic obesity, but the risk wasn’t evenly distributed: women were affected at a higher rate than men (2.6% versus 1.5%). The participants were all 65 or older and the criteria are specific to Asia-Oceania populations, so the 2% figure does not transfer to other populations or to younger adults.
What predicts getting worse
Over one year of follow-up, new cases of sarcopenic obesity appeared in about 1% of participants, and “possible” sarcopenic obesity (an earlier-stage warning sign) appeared in about 3%. Among the factors linked to someone’s condition getting worse over that year were hypertension (odds ratio 3.67, 95% CI 1.26 to 10.66) and diabetes (odds ratio 4.01, 95% CI 1.07 to 15.12); the intervals are wide, so treat the size as rough. On the flip side, regular exercise was linked to better odds of improvement (odds ratio 0.46 in models adjusted for age and sex only), and higher education levels were also listed as protective.
The one-year window is short, and with only 1,048 participants and a low baseline prevalence, the study can’t tell us everything about long-term trajectories. This study found associations; it did not test whether controlling blood pressure and blood sugar prevents the decline, though that may be worth discussing. If you’re managing hypertension or diabetes and haven’t talked with your doctor about how it connects to your muscle mass and physical function, that’s a conversation worth having, especially paired with a regular movement routine.

DOI: 10.1016/j.jfma.2026.08.056. Finding used: in 1,048 Taiwanese adults 65+, baseline sarcopenic obesity prevalence was 2.0% (2.6% in women vs. 1.5% in men); one-year incidence was 1% (sarcopenic obesity) and 3% (possible sarcopenic obesity); hypertension (OR 3.67) and diabetes (OR 4.01) were associated with deterioration (wide confidence intervals: 1.26-10.66 and 1.07-15.12), while regular exercise (OR 0.46 in age- and sex-adjusted models) and higher education were associated with improvement. ↑︎
