Key result
Living at high altitude in Derong, China was associated with an overall metabolic syndrome prevalence of 3.6% among 5,053 adults, with higher rates in men and township residents.
Why the study?
Metabolic syndrome is a major cardiovascular disease risk factor, but little information exists regarding its prevalence in high-altitude areas in China.

What is the prevalence of metabolic syndrome in adults living at high altitude in Derong, China?
The prevalence of metabolic syndrome is relatively low (3.6%) in high-altitude residents of Derong, China, though hypertension and obesity are common.
Low MetS prevalence at altitude cautions against broad risk extrapolation; leaves open altitude-specific factors for prospective confirmation.
OBJECTIVE: The metabolic syndrome is a major risk factor for cardiovascular disease. Little information exists on the prevalence of the metabolic syndrome at high-altitude areas in China. We aimed to estimate the prevalence of metabolic syndrome and its individual components at high altitude. METHODS: A cross-sectional survey of 5053 adults living in Derong from elevation of 2060 to 3820 m was carried out in 2013. Metabolic syndrome was defined according to the Chinese Diabetes Society criteria. RESULTS: The overall prevalence of metabolic syndrome was 3.6% (5.9% in men and 1.8% in women) in Derong, China. Obesity and hypertension were more prevalent among adults than dyslipidaemia and hyperglycaemia at high altitude. The prevalence of metabolic syndrome was higher in township than countryside residents (6.6%, 11.9% in men and 1.5% in women vs 3.0%, 4.6% in men and 1.8% in women). Men with age 30-59 years old had a much higher prevalence of metabolic syndrome than women. Men, township, middle and old age residents had a higher risk of metabolic syndrome. The risk of obesity and dyslipidaemia decreased and the risk of hypertension increased in very high altitude (≥3000 m) residents. CONCLUSION: In Derong, despite the relatively low prevalence of metabolic syndrome, hypertension and obesity are more prevalent in adult residents. And metabolic syndrome is more concentrated in township and male residents. These people also have a higher risk of metabolic syndrome. Therefore, it is necessary to develop a national strategy for the prevention and treatment of metabolic syndrome for high-risk population at high altitude in China.
