Objectives Adipose tissue hypoxia appears to play a role in promoting chronic inflammation and the development of obesity‐related cardiovascular and metabolic diseases, yet the underlying mechanisms are not well understood. The aim of the present research is to examine whether adiponectin levels (an adipocyte‐derived hormone with anti‐inflammatory properties) are inversely correlated with hemoglobin levels in an indigenous Siberian population. Methods The study was conducted among 252 Yakut adults (≥18 years; 135 females) from Berdygestiakh, Sakha Republic, Russia. Measurements included anthropometric dimensions (body mass index [BMI], waist circumference [WC], and percent body fat) and blood levels of hemoglobin and adiponectin. Results Yakut females had higher adiponectin concentrations than males (15.1 ± 9.8 vs. 11.7 ± 10.6 µg/ml; P < 0.001), whereas males had higher hemoglobin levels (14.4 ± 1.4 vs. 12.6 ± 1.5 g/dL; P < 0.001). Body composition measures in both sexes were negatively associated with adiponectin and positively associated with hemoglobin. After adjusting for central adiposity and smoking, adiponectin levels were negatively correlated with hemoglobin levels in men ( P < 0.05), but not in women ( P = 0.511). Conclusions This investigation provides some support for the involvement of hypoxia‐related dysregulation of adiponectin associated with obesity and potentially cardiovascular disease. Am. J. Hum.
