Metabolic syndrome and its association with changes in modifiable risk factors: Epifloripa aging study.

Purpose: To estimate the prevalence of Metabolic Syndrome (MetS) and its association with changes in modifiable risk factors in older adults from southern Brazil.
Methods: A longitudinal study was performed with data from EpiFloripa Aging study. We defined MetS by the existence of three or more of the following risk factors for cardiovascular disease (CVD): waist circumference (WC) (≥ 92 cm in men and ≥ 87 cm in women); fasting glucose (≥100 mg/dl); decreased HDL cholesterol (<40 mg/dl in men and <50 mg/dl in women); hypertriglyceridemia (≥150 mg/dl) and blood pressure (≥130/85 mmHg). We evaluated the changes in modifiable risk factors (smoking, alcohol consumption, fruit and vegetable consumption, physical activity, and body mass index) between the two moments of the study (2009/10 and 2013/14). Directed acyclic graph and logistic regression models were used.
Results: Among the 599 participants, the prevalence of MetS was 64.0% (95% CI, 58.7-68.9). In the adjusted analysis, those who remained or became persons who are overweight (OR = 4.59; 95% CI: 3.05-6.89) and those who remained or became insufficiently active (OR = 1.92; 95% CI: 1.23-2.98) were more likely to present MetS.
Conclusion: Our findings suggest that being or becoming overweight and being or becoming insufficiently active are modifiable factors associated with MetS. These results highlight the need for developing preventive strategies for the observed risk indicators to mitigate the prevalence of MetS in older adults. © Springer Nature Switzerland AG 2022.
