High absolute fat mass was independently associated with an increased risk of silent brain infarction or white matter changes in women (adjusted OR 2.02; 95% CI 1.06-3.86; P=0.03), but not overall.

Does high absolute fat mass increase the risk of silent brain infarction or white matter changes in adults without prior stroke or dementia?
High absolute fat mass may be an independent risk factor for silent cerebrovascular lesions in women without a history of stroke or dementia.

Obesity is known to increase the risk of stroke. It is unclear whether high absolute fat mass (FM) increases the risk of stroke independently. We studied the correlation between FM and silent brain infarction/white matter change (SI/WMC) using brain computed tomography. We selected subjects from the local government health promotion project. We randomly selected a target population that had never been diagnosed with stroke or dementia. FM was measured by bioelectrical impedance analysis (BIA). We divided the subjects into three groups according to the FM (gender-specific tertiles GTx). Seven hundred and twenty-two subjects (321 men) between 50 and 75 years of age were recruited. The overall odds ratio (OR) of SI/WMC was 2.23 (95% confidence interval (CI), 1.34–3.71; p = 0.002) times higher in the 37th to 100th percentiles (GT3) than in the first to 32nd percentiles (GT1). When men and women were separated, the OR of GT3 was 1.35 (CI, 0.62–2.94; p = 0.45) in men and 3.2 (CI, 1.60–6.40; p = 0.001) in women. The findings were not found to be statistically significant after adjusting for the well-known stroke risk factors. When the subjects were divided into a high FM (HFMG, GT3) and low FM group (LFMG, GT1 + GT2), the HFMG showed an increased OR of SI/WMC in women. Similar results were seen after adjusted (overall: OR, 1.38; CI, 0.85–2.25, p = 0.198; men: OR, 0.93; CI, 0.422–2.051; p = 0.86; women: OR, 2.02; CI, 1.06–3.86; p = 0.03). The findings suggest that high FM may be an independent risk factor for ischemic stroke among adults free from stroke and dementia, especially in women.
Koh et al. (Thu,) conducted a cross-sectional in Silent brain infarction and white matter changes (n=722). High absolute fat mass vs. Low absolute fat mass was evaluated on Silent brain infarction/white matter change (SI/WMC) (OR 2.23, 95% CI 1.34-3.71, p=0.002). High absolute fat mass was independently associated with an increased risk of silent brain infarction or white matter changes in women (adjusted OR 2.02; 95% CI 1.06-3.86; P=0.03), but not overall.
