Dietary Patterns Are Associated with Metabolic Syndrome in Mexican Older Adult Population.

Background: Metabolic syndrome poses a significant public health challenge globally, particularly among older adults. Dietary patterns play a crucial role in the development and management of metabolic syndrome. However, to our knowledge, no evidence exists regarding the association between dietary patterns and metabolic syndrome among the Mexican older adult population. Thus, the objective of the present study is to assess the association between dietary patterns and metabolic syndrome in Mexican older adults.

Methods: This cross-sectional study utilized data from the Mexican National Health and Nutrition Survey 2016 to investigate the relationship between dietary patterns and metabolic syndrome in 804 OA (aged ≥60 years). Dietary patterns were derived using factor analysis, and metabolic syndrome was defined based on established criteria. Logistic regression models were employed to assess associations, adjusting for potential confounders.

Results: Three dietary patterns were identified: a "Westernized" pattern characterized by high consumption of processed meat, red meat, and saturated fats; a "Transitional" pattern high in fresh vegetables and fruits; and a "Prudent" pattern high in fish and low-fat dairy products. The "Westernized" pattern exhibited a positive association with metabolic syndrome, while the "Prudent" pattern showed a negative association. The associations remained significant after adjusting for confounders. Biological mechanisms linking the "Westernized" pattern to metabolic syndrome include chronic inflammation, endothelial dysfunction, and dyslipidemia induced by components such as processed meats and soft drinks.

Conclusion: Our study highlights the importance of dietary patterns in influencing metabolic syndrome risk among Mexican older adults. Promoting dietary patterns rich in fish, vegetables, and legumes while reducing consumption of processed meats and sugary beverages may offer significant health benefits in this population. Further prospective studies are needed to confirm these findings and inform targeted interventions for metabolic syndrome prevention and management in older adults.
