Официальное название
Association Between Serum 25-Hydroxyvitamin D Status and Lipid Profile Among Obese Adults With Type 2 Diabetes Mellitus: A Cross-Sectional Study
Обзор
This prospective, single-center, cross-sectional observational study aims to evaluate the association between serum 25-hydroxyvitamin D concentrations and lipid profile parameters among adults with obesity and established type 2 diabetes mellitus. A total of 160 participants will be recruited from an outpatient diabetes clinic in Cairo, Egypt. Each participant will undergo a single clinical, anthropometric, and laboratory assessment. No intervention or treatment will be assigned by the investigators.
Подробное описание
\*\*Detailed Description\*\*
This prospective, single-center, cross-sectional observational study is designed to investigate the association between serum 25-hydroxyvitamin D \[25(OH)D\] status and lipid profile parameters among obese adults with established type 2 diabetes mellitus (T2DM).
The study will recruit adult participants with obesity and T2DM attending an outpatient diabetes clinic in Cairo, Egypt. Eligible participants will undergo a baseline clinical and laboratory assessment after providing written informed consent.
The primary objective of this study is to evaluate whether serum 25(OH)D concentrations are associated with lipid profile parameters, including total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C).
Secondary objectives include evaluating the association between serum vitamin D status and glycemic characteristics, including fasting blood glucose, postprandial blood glucose, glycated hemoglobin (HbA1c), and serum insulin levels.
During the study visit, demographic and clinical data will be collected, including age, sex, diabetes duration, body mass index (BMI), and relevant medical history. Anthropometric measurements and blood pressure assessment will be performed. Fasting blood samples will be collected for biochemical analyses, including serum 25(OH)D concentration, glucose parameters, insulin, and lipid profile measurements.
Participants will be categorized according to their serum 25(OH)D status based on predefined criteria. Statistical analyses will be performed to assess differences between vitamin D status groups and to evaluate correlations between serum 25(OH)D concentrations and cardiometabolic parameters.
No intervention, medication assignment, or vitamin D supplementation will be administered as part of this study. The study is observational in nature and aims to identify associations between vitamin D status and metabolic characteristics among obese adults with T2DM.
All procedures will be conducted according to the approved study protocol and ethical principles for research involving human participants. Written informed consent will be obtained from all participants before enrollment.
