Understanding Overweight and Obesity: Key Differences and Health Implications in Singapore

The terms "overweight" and "obesity" are often used interchangeably, but they represent different points on the spectrum of excess body weight. Both conditions are determined using the Body Mass Index (BMI), a simple calculation based on an individual's weight and height. A BMI between 25 and 29.9 is classified as overweight, while a BMI of 30 or higher is considered obese[1].


Health Implications

Both overweight and obesity are associated with an increased risk of various health issues:

  • Type 2 Diabetes: Approximately 90% of individuals with type 2 diabetes are overweight or obese[2].
  • Cardiovascular Diseases: Excess weight contributes to hypertension, high cholesterol, and other factors that elevate the risk of heart disease and stroke[3].
  • Certain Cancers: Obesity has been linked to an increased risk of cancers such as breast, colon, and endometrial cancer[4].


Overweight and Obesity in Singapore

Singapore has witnessed a concerning rise in obesity rates. According to the 2021/2022 National Population Health Survey, the prevalence of obesity among residents aged 18 to 74 years increased from 10.5% in 2019/2020 to 11.6% in 2022[5]. Notably, obesity rates are higher in males than in females.



Limitations of BMI

While BMI is a useful screening tool, it does not account for factors such as muscle mass, bone density, and distribution of fat. For instance, athletes with high muscle mass may have a high BMI without excess body fat[6]. Therefore, BMI should be used alongside other assessments to evaluate an individual's health comprehensively.


Conclusion

Understanding the distinctions between overweight and obesity is crucial for addressing the associated health risks. In Singapore, the rising prevalence of these conditions underscores the need for effective public health strategies, including promoting balanced nutrition, encouraging regular physical activity, and providing access to healthcare services for weight management.
