Sex-differences in dietary macronutrient intake and its association with metabolic syndrome components in adults with type 2 diabetes: a cross-sectional study
Abstract
Metabolic syndrome (MetS) is highly prevalent in patients with type 2 diabetes (T2D) and increases cardiovascular risk. Sex-specific associations between macronutrient intake and MetS remain insufficiently explored. This study aimed to assess MetS prevalence and examine sex differences in associations between dietary macronutrient intake and MetS components. A cross-sectional study was conducted among 425 Moroccan adults with T2D. MetS was defined using harmonized IDF, AHA, and NHLBI criteria. Dietary intake was assessed using a 24-hour recall, and isoenergetic macronutrient substitution models were applied. The prevalence of MetS was 72.9%, higher in women than men (81.2% vs. 58.4%). Women showed higher BMI, waist circumference, and poorer metabolic profiles. In men, MetS was associated with central obesity, inadequate sleep, and family history of cardiometabolic disease. Replacing protein with fat was associated with lower odds of MetS (OR=0.58; 95% CI: 0.35–0.98), abdominal obesity (OR=0.60; 95% CI: 0.37–0.97), and hypertriglyceridemia (OR=0.57; 95% CI: 0.33–0.95). No significant associations were observed in women. MetS is highly prevalent among Moroccan adults with T2D, with clear sex differences. Macronutrient substitution was associated with favorable metabolic outcomes only in men, highlighting the importance of sex-specific nutritional strategies.
