Background: Obesity has been linked to the development of type 2 diabetes mellitus and cardiovascular diseases. This study primarily aims to determine the prevalence of obesity among the Filipino patients in our institution since there have been no previous studies on this subset of patients.
Methodology: This was a retrospective analytical study of 2,082 patients at the Primary Preventive Cardiology Clinic of the Philippine Heart Center (PHC) from January 1, 2002 to December 31, 2017. The prevalence of obesity was determined using the World Health Organization (WHO) and the Asian classification. Factors associated with obesity were determined using binary logistic regression analysis.
Results: The mean age was 57.1 + 10.9 years with a female predominance (1509, 72.5%). There were more unemployed female patients than men (1, 135, 75.2% vs 263, 45.9%, p <0.001). Hypertension was the most common co-morbid illness (68.4%) in both genders followed by coronary artery disease (37.1%) and type 2 diabetes mellitus (20.3%). The mean body mass index (BMI) of the female patients was 25.8 + 4.3 while it was 25.2 + 4.1 for the male patients (p<0.001). The prevalence of obesity using the WHO and Asian classifications was 15% (312). Compared to the Asian criteria, there were significantly more patients classified as having normal weight (44.09% vs 24.95%, p<0.001) and overweight (37.98% vs 19.13%, p<0.001) using the WHO classification. Pre-obesity, an additional criterion of the Asian classification which was not adopted by WHO, was seen in 37.98% of the patients.
Conclusion: The prevalence of obesity in our cohort is consistent with the reported worldwide prevalence by the WHO. Age, female gender and type 2 diabetes mellitus were significant factors associated with obesity.
