ABSTRACT
Objective: To compare the lipid profile of the subclinical and clinical hypothyroid patients and to evaluate the correlation between body mass index [BMI] and lipid profile in hypothyroidism
Study Design: Cross-sectional study
Place and Duration of Study: Islamic International Medical College, Riphah International University, Islamabad, and Citi Laboratory, Rawalpindi, from January to December 2013
Methodology: The subjects were selected through non-probability, purposive sampling. On the basis of thyroid profile, the subjects were divided into 3 groups: euthyroids [n=20], subclinical hypothyroids [n=50], and clinical hypothyroids [n=30]. The blood of these subjects was then analyzed for lipid profile. Data was analyzed using SPSS version 18 statistical software
Results: Both hypothyroid groups showed altered lipid profile which was observed to be significantly raised when compared with the euthyroid subjects. Comparison of lipid profile in euthyroid, subclinical, and clinical hypothyroid groups showed significant differences by non-parametric tests [p < 0.05]. An assessment of correlation of lipid profile with the BMI was found to be significant [p < 0.01]
Conclusion: Hypothyroidism causes alteration of lipid profile. Clinical and subclinical hypothyroid patients have altered lipid profile as compared to euthyroids. Thyroid status monitoring is very important, since it can induce changes in lipid profile. Such dyslipidemic status is significant not only for the management of thyroid disorders but also for common diseases like obesity and coronary atherosclerosis in the population
