The prevalence of sarcopenia in non-hospitalized elderly people was 9.0%-18.5% in the plain region. However, epidemiological investigations of sarcopenia in plateau regions are limited. The city of Xining in Qinghai Province (altitude 2260 m) is the sole point of access to the Qinghai-Tibet plateau, where people live with diverse ethnicities and dietary habits including high salt and fat intake, brewed tea, and ghee, beef, and mutton.
We explored how diverse ethnicities and dietary habits affect the risk of sarcopenia. Beef and mutton have high protein content and high protein intake was previously reported as protective against sarcopenia.
To investigate the prevalence and risk factors of sarcopenia in geriatric patients from the Qinghai-Tibet plateau region.
Data included demographics, history of falls, nutritional status, self-care ability, depression, handgrip, muscle mass, and 6-m gait speed. The independent-sample t-test and chi-squared test were used to evaluate differences between groups with and without sarcopenia. Factors associated with sarcopenia were determined by binary logistic regression analysis. A P-value < 0.05 was considered a significant difference.
The overall rate of sarcopenia was 20%. Widowhood was associated with sarcopenia, while higher body mass index and beef and mutton consumption were protective.
The prevalence of sarcopenia in hospitalized geriatric patients in the Qinghai-Tibet plateau region was higher than that in the plain region and in non-hospitalized geriatric people. Ethnicity, and consumption of brewed tea or ghee have no significant effect on sarcopenia. Consumption of beef and mutton is protective against sarcopenia.
We plan to explore diagnostic cut-off points in Xining City based on big data, and a risk assessment system will be developed.
