Globally, however, the authors found that the percentage of men who now have diabetes has risen by 18 percent over the past 30 years, climbing from just over 8 percent to nearly 10 percent in that time.
Among women, the rise was even steeper, amounting to a 23 percent spike in the same period, as the incidence crept up from 7.5 percent to slightly more than 9 percent.
Other nations where diabetes has exploded in recent years include Pacific Island countries, such as the Marshall Islands (where one-third of the women and one-quarter of the men have diabetes) and Saudi Arabia. Diabetes and glucose levels in South and Central Asia, Latin America, the Caribbean, North Africa and the Middle East were also especially high.
In contrast, the occurrence of diabetes in Eastern Europe appears to have remained stable over the last 30 years, while blood sugar levels appear to be lowest in sub-Saharan Africa and east and southeast Asia.
Ezzati and Danaei suggest that more than two-thirds of this rise (70 percent) can be attributed to a world in which aging people are living longer, as diabetes risk goes up with age. An increase in the obesity rate, higher body mass indexes (BMI) and other critical risk factors unrelated to age accounts for the remaining 30 percent, they said.
Genetic factors associated with ethnic origin, nutrition in the womb and early life, diet quality, and physical activity might also affect these trends, the authors reported in the news release.
Without better programs for detecting people with elevated blood sugar and helping them to improve their diet, get more exercise and control their weight, "diabetes will inevitably continue to impose a majo
