Frequency of Dyslipidemias in Non-Diabetic and Obese Subjects

Background: Obesity is now considered as an emerging epidemic worldwide. It is associated with dyslipidemias and is considered independent cardiovascular risk factor in many subjects. Obesity and its metabolic consequences are worldwide epidemics. Aim: To determine frequency of dyslipidemias in non-diabetic obese subjects presenting to a tertiary care hospital in Lahore. Methods: This cross sectional study was carried out in medical inpatient and outpatient departments of Sir Ganga ram Hospital, Lahore during six months, from 12th August 2016 to 11th February 2017. Patients were interviewed for absence of diabetes mellitus, hypertension, renal, hepatic or cardiac disease, family history of dyslipidemias, smoking and drinking alcohol. Body weight in kilograms and height in centimeters was measured to calculate BMI. Results: There were 93 (46.5%) males and 107(53.5%) females. The mean BMI of patients was 36.07 +/- 3.25 kg/m(2); 79 (39.5%) patients with grade I obesity (BMI 30.0-34.9 kg/m(2)), 92 (46%) patients with grade II obesity (BMI 35.0-39.9 kg/m(2)) and 29 (14.5%) patients with grade III obesity (BMI >= 40.0 kg/m(2)). Raised total cholesterol >200mg/dl was present in 155(77.5%) patients and absent in 45(22.5%) patients. Conclusion: Prevalence of dyslipidemia was both age and body mass index dependent. Dyslipidemia showed an increasing trend with age >= 38 years. Patients with increased body mass index had increased prevalence of dyslipidemia which is an eye opener for the health policy makers to devise the strategies to delay the onset of this preventable disease.
