Key result

Metabolic syndrome defined by the NCEP ATP III criteria was associated with a significantly higher risk of new-onset cardiovascular disease in rural elderly females (HR 1.45), but not in males.

Why the study?

It was unknown whether metabolic syndrome and its components could predict cardiovascular disease in a rural elderly Chinese population.

Does metabolic syndrome predict newly onset cardiovascular disease in an elderly rural Chinese population?

Population

2486 elderly individuals from rural China

Comparison

Metabolic syndrome and its components vs absence

Design

Longitudinal cohort study

Overview

MetS predicted incident CVD in rural elderly Chinese women but not men; leaves open sex-specific screening utility pending prospective validation.

Study Design

Type

Cohort (n=2,486)

Structured PICO

Does metabolic syndrome predict newly onset cardiovascular disease in an elderly rural Chinese population?

P
Population
2,486 elderly adults (aged ≥ 60 years) from rural China were followed for a median of 4.66 years to evaluate the predictive effect of metabolic syndrome on new-onset cardiovascular disease.
E
Exposure
Metabolic syndrome (MetS) defined by NCEP ATP III, AHA/NHLBI, or IDF criteria
C
Comparator
Absence of metabolic syndrome
O
Outcome
Newly onset cardiovascular disease (CVD), including stroke and coronary heart disease (CHD)hard clinical

Main Result

Hazard Ratio: 1.45 (95% CI 1–2.1)

Metabolic syndrome is a significant predictor of incident cardiovascular disease in elderly rural Chinese females, but not males, highlighting a gender discrepancy in risk.

Limitations

  • Some participants were lost to follow-up, which might cause bias.
  • HDL-C, LDL-C, triglyceride, and fasting plasma glucose were measured only once, which might be imprecise.
  • Lack of data on insulin resistance prevented the use of WHO or European Group definitions.
  • Details on the variety and dosage of antihypertensive, antidiabetic, and antidyslipidemic medications were not collected.

Yu et al. (2021) conducted a cohort in Cardiovascular disease (n=2,486). Metabolic syndrome (NCEP ATP III criteria) vs. Without metabolic syndrome was evaluated on New-onset cardiovascular disease (CVD) in females (HR 1.45, 95% CI 1.00, 2.10). Metabolic syndrome defined by the NCEP ATP III criteria was associated with a significantly higher risk of new-onset cardiovascular disease in rural elderly females (HR 1.45), but not in males.
