Study summary

Long-term Impact of Overweight/Obesity and Hypertension on Cardiovascular Risk in Middle-aged and Elderly Adults

Read the detailed description

Overweight and obesity are major risk factors associated with the development of hypertension, poor blood pressure control, and adverse cardiovascular outcomes. However, evidence regarding the long-term impact of overweight/obesity and hypertension on cardiovascular risk in middle-aged and elderly populations remains limited. Therefore, the present study aims to evaluate the long-term effects of overweight/obesity and hypertension on cardiovascular risk in middle-aged and elderly adults.Additionally, a subgroup analysis will be conducted in participants with sarcopenia to assess the influence of blood pressure on prognosis, exploring potential interactions between muscle loss, hypertension, and cardiovascular outcomes.
