Non-Communicable Disease (NCD) Deaths Vs Overweight and Obesity

  Overweight and obesity are the most common metabolic risk factors for NCDs deaths in SEAR countries.

BMI Definition

  Body Mass Index (BMI) indicates a person’s obesity and overweight, which is calculated by weight and height.

  Truncal obesity is defined in terms of waist–hip (or waist–height) ratio.

  There is a slight difference between overweight and obesity.

  A person with BMI between 25.0 and 29.9 is considered overweight and ≥30.0 is considered obese.

Impact of Overweight and Obesity

  Major causes of overweight and obesity are type 2 diabetes and cardio vascular disease, high blood pressure, blood glucose and cholesterol levels.

Death Occurrence

  Overweight and obesity are the fifth leading risk factors for global deaths. Nearly 2.8 million deaths occur every year.

  In SEAR countries nearly 0.35 million deaths occurred due to overweight and obesity.

  Except Nepal, variations in prevalence of overweight and obesity have been found in males and females (in males 8% to 30% and in females 8% to 52%). Maldives attained the highest position with 30% in males and 52% in females followed by Thailand with 26% and 36% respectively.

Highlights in Member Countries

  The prevalence of obesity was positively correlated with age, wealth and urban residence.

  Among males, obesity prevalence increased from 23% in 2004 to 29% in 2009 where as 35% in 2004 to 41% in 2009 among females in Thailand.

  An increase was seen among both males and females waist circumference.

  In Thailand, socioeconomic status strongly influences obesity in males, but not in females.

  In Jaipur (India), age-adjusted prevalence of obesity among adults of age 20–59 years was 9.5% in persons with low education and 17% in persons with high education

  Burden of obesity is shifting towards individuals of lower socioeconomic status in 14 lower-to middle-income countries including India.
