Number of adults with diabetes reaches 422 million worldwide, with fastest increases in low and middle income countries

160406074921_1_900x600Since 1980, the number of adults with diabetes worldwide has quadrupled from 108 million to 422 million in 2014, . The findings provide the most comprehensive estimates of worldwide diabetes trends to date and show that diabetes is fast becoming a major problem in low and middle income countries.

“Diabetes has become a defining issue for global public health. An aging population, and rising levels of obesity, mean that the number of people with diabetes has increased dramatically over the past 35 years” says Professor Majid Ezzati, senior author from Imperial College London, London, UK. “Rates of diabetes are rising quickly in China, India, and many other low and middle income countries, and if current trends continue, the probability of meeting the 2025 UN global target is virtually non-existent.”

The study, released ahead of World Health Day (7th April), includes data from 751 studies totalling 4.4 million adults in different world regions. The study estimates age-adjusted diabetes prevalence for 200 countries — meaning that researchers adjusted the results to account for diabetes becoming more common as a person ages and for some countries having older populations.

Between 1980 and 2014, diabetes has become more common among men than women. Global age-adjusted prevalence of diabetes doubled among men (4.3% to 9.0%) and increased by two-thirds among women (5.0% to 7.9%).

Although there was an increase in overall rates (crude prevalence) of diabetes in many countries in Western Europe, age-adjusted rates were relatively stable suggesting that most of the rise in diabetes in Western Europe between 1980 and 2014 was due to the aging population. In contrast, rates of diabetes increased significantly in many low and middle income countries — such as China, India, Indonesia, Pakistan, Egypt and Mexico. No country saw a significant decrease in diabetes prevalence.

The study did not differentiate between type 1 and type 2 diabetes, but most (85-95%) of cases of adult diabetes are type 2 so the observed rise is likely to be due to increases in type 2 diabetes.

Professor Ezzati adds: “Obesity is the most important risk factor for type 2 diabetes and our attempts to control rising rates of obesity have so far not proved successful. Identifying people who are at high risk of diabetes should be a particular priority since the onset can be prevented or delayed through lifestyle changes, diet or medication.”

National and regional findings include:

– In the UK, after adjusting for an aging population, 4.9% of women have diabetes in 2014 (compared to 4.0% in 1980). Prevalence has increased more among men, from 4.8% in 1980 to 6.6% in 2014.

– Northwestern Europe has the lowest rates of diabetes among women and men, with age-adjusted prevalence lower than 4% among women and at 5-6% among men in Switzerland, Austria, Denmark, Belgium and the Netherlands.

– Prevalence of diabetes was highest in Polynesia and Micronesia (age-adjusted prevalence is over 20% in men and women). In American Samoa, nearly one third of the adult population have diabetes.

– The greatest increases in diabetes prevalence were in Pacific island nations, followed by the Middle East and North Africa, in countries like Egypt, Jordan and Saudi Arabia.

– Half of adults worldwide with diabetes in 2014 lived in five countries: China, India, USA, Brazil and Indonesia.

– Age-adjusted prevalence of diabetes has more than doubled for men in India and China (3.7% to 9.1% in India; 3.5% to 9.9% in China); and increased by 50% among women in China (5.0% to 7.6%) and 80% among women in India (4.6% to 8.3%).

– In the US, age-adjusted prevalence of diabetes in women increased by 50% (4.3% to 6.4%), and 80% in men (4.7% to 8.2%).

– Pakistan, Mexico, Egypt and Indonesia are all now in the top 10 countries with the largest number of adults with diabetes. Age-adjusted prevalence of diabetes doubled in Pakistan (4.9 to 12.6% for men and 5.9 to 12.1% for women), Mexico (6.5 to 10.9% for men and 6.5 to11.5% for women), and Indonesia (3.2 to 7.4% for men and 4.1 to 8.0% for women) and nearly tripled in Egypt (6.5 to 16.0% for men and 8.0% to 19.8% for women).

Writing in a linked Comment, Etienne Krug, Management of Noncommunicable Diseases, Disability, Violence and Injury Prevention, World Health Organization, Geneva, Switzerland, says: “The prevalence estimates provided by the NCD-Risk Factor Collaboration sound the alarm for large-scale, effective action to reduce the health and economic impact of diabetes. Improvements in prevention and management, together with better surveillance, should be prioritised in response to this call.”

MP mulls selling of power to northern states

Posted on

In a bid to cash in on monsoon, Madhya Pradesh has firmed up a plan to mop up revenue of about Rs 60 crore through sale of electricity to other northern states, official sources said. The monsoon usually hits northern states 15 to 20 days after it drenches the state where sufficient electricity is available from June 20 as the dams receive enough water for hydel power generation.
The state gets more than 2,000 mw from hydel projects, including from state-centre joint ventures (JVs). The energy demand comes down considerably as the weather turns pleasant during the monsoon, officials said. The demand for power comes down by 2,000 mw in the state after the onset of monsoon, they said.
Right now the power demand is between 5,500 mw – 6,000 mw, which is likely to drop to around 4,000 mw after the rainfall,
Looking at this, MP Power Management Company Ltd. (MPPMCL) has firmed plans to sell around 60 lakh electricity units per day for 20 days .
The state is likely to get an average Rs 5 per unit of electricity on account of such power sale to different states, they added. MP power sector wants to earn some money from the sale of energy to make up for losses given that the three discoms – MP Central, MP Eastern and MP Western are incurring loss of more than Rs 200 crore monthly.
“We have plan to sell power to Rajasthan, Uttar Pradesh, Haryana, Punjab and Delhi where the monsoon reaches little later than MP,” an official said.
Now it all depends when the monsoon will hit the state as the mansoon has not reached on the forecasted date of 21 June. Hopefully forecast it should hit the city by 3rd July (as per the latest )
