Association of Uroguanylin, Body Mass Index, and Waist Circumference: Sex Differences and Obesity Implications among a Sample of Iraqi Adults in Baghdad City.

This research investigates the gender-specific associations of uroguanylin levels with various health-related parameters in Iraqi adults. The results revealed significant differences between genders in food style preferences and waist circumference (WC) risk. Notably, uroguanylin exhibited distinct correlations with low density lipoprotein (LDL) cholesterol, glycated hemoglobin (HbA1c), body mass index (BMI), and WC in females and males, indicating potential gender-specific effects on lipid metabolism, glucose regulation, and adiposity. A total of 140 Iraqi adults (73 females and 67 males) were recruited into the study. Physical activity levels, food style preferences, WC risk, and BMI subgroups, were compared between genders. Additionally, participants' characteristics, including age, height, weight, BMI, blood pressure, cholesterol levels, and uroguanylin concentrations, were analyzed. Significant gender differences were observed in food style preferences, with a higher proportion of males preferring fast food, with a greater percentage of females classified as having a high risk, females exhibited lower height and weight compared to males. HbA1c levels were significantly lower in females, whereas high density lipoprotein (HDL) cholesterol levels were significantly higher in females than in males. Uroguanylin concentrations were also significantly lower in females compared to males. Uroguanylin shows a moderately negative correlation with LDL cholesterol in females but not in males. Furthermore, a strong negative association between uroguanylin and HbA1c in females indicated improved glycemic control with higher uroguanylin levels, whereas an opposite trend was observed in males. No significant association was observed between uroguanylin and BMI in females, a significant positive correlation was found in males. For WC, a weak negative correlation was noted in females, whereas a moderately negative correlation was observed in males. These contrasting correlations imply potential gender-specific effects of uroguanylin on adiposity and body fat distribution.
