Key result
Age <55 years, non-current smoking, pre-menopause, and non-hyperuricemia were independent predictors of metabolically healthy obesity, which had an overall prevalence of 23.1%.

What is the prevalence and what are the predictors of metabolically healthy obesity in an obese rural population in China?
In a rural Chinese population with obesity, nearly a quarter have metabolically healthy obesity, which is independently predicted by younger age, non-smoking, pre-menopausal status, and absence of hyperuricemia.

Initial MHO prevalence data in rural China; hypothesis-generating and should not yet inform risk stratification or practice.
Till now, no evidence illustrates the prevalence and predictors of metabolically healthy obesity (MHO) in rural areas of China. The objective of this study was, firstly, to examine the prevalence of MHO in rural areas of China, and identify contributing determinants of MHO, Secondly, to comprehensively investigate to the different characteristics between MHO and metabolically unhealthy obesity (MUO). We conducted a population-based cross-sectional study of 2037 participants with obesity in rural Liaoning Province during 2012–2013. Obesity was defined as BMI ≥28 kg/m2 and metabolically healthy was defined as not having the metabolic syndrome. The prevalence of MHO was 23.1%, and significantly decreased with advancing age in female group. However there was no significant tendency with advancing age in male group. Independent determinant factors for MHO were age <55 years (odds ratio [OR] 1.659; p = .001), non-current smoking (OR 1.397; p = .038), pre-menopause (OR 1.648; p = .030) and non-hyperuricemia (OR 2.317; p < .001), whereas race, gender, diet score, current drinking, marriage, sleep duration, hyperhomocysteinemia, levels of physical activity, annual income and educational status were not significant contributors. In conclusion, we found that age <55 years, non-current smoking, pre-menopause and non-hyperuricemia were identified as independent determinant factors for MHO in this population.

Zhang et al. (2016) conducted a cross-sectional in Obesity (n=2,037). Age <55 years, non-current smoking, pre-menopause, and non-hyperuricemia vs. Older age, current smoking, post-menopause, and hyperuricemia was evaluated on Prevalence of metabolically healthy obesity (MHO). Age <55 years, non-current smoking, pre-menopause, and non-hyperuricemia were independent predictors of metabolically healthy obesity, which had an overall prevalence of 23.1%.
