NEW YORK (Reuters Health) Jan 13 - Despite being thinner, Asian Americans are more likely than whites to have type 2 diabetes - and the problem is growing, a new study finds.
Using data from the ongoing government National Health Interview Survey, researchers found that Asian Americans had consistently higher rates of type 2 diabetes than white Americans.

What's more, diabetes rates rose over time for both racial groups -- reaching 8% among Asian adults and 6% among whites.
The findings, reported online January 7 in Diabetes Care, are in line with past studies showing that Asian background itself is a risk factor for diabetes.
But while researchers know that Asians are at increased diabetes risk, most people are probably unaware of that, said Dr. Hsin-Chieh "Jessica" Yeh, from Johns Hopkins University in Baltimore and the senior researcher on the new study.

Genes are partly to blame, Dr. Yeh told Reuters Health in an email. But it's the combination of genetic vulnerability and lifestyle that's key, she pointed out.
"Asians may be even more susceptible to unhealthy food and related weight gain," Dr. Yeh said.
Specifically, studies have shown that even though Asian adults tend to weigh less than white and black adults, they often have a higher percentage of fat surrounding their abdominal organs. Visceral fat is particularly linked to the risk of type 2 diabetes.
Then there's exercise: Based on health surveys, Asian immigrants to the U.S. are less physically active than native-born non-Asians, Dr. Yeh and her colleagues note.
Their study included 230,500 U.S. adults who took part in the survey between 1997 and 2008. Just over 11,000 were Asian American, with the majority being foreign-born.
Over the 12 years of the study, the number of Asian Americans reporting a diabetes diagnosis rose from just over 4% to 8%. Among white adults, the prevalence rose from just under 4% to 6%.
Yet in 2006 to 2008, 25% of whites were obese, versus 17% of Asians.
When Dr. Yeh's team accounted for factors like age, BMI, income and reported exercise levels, Asian background itself was linked to a 30% to 50% higher likelihood of having diabetes.
The researchers acknowledge study limitations, including possible selection bias, misclassification of race and inaccurate responses to questionnaires.
Despite this they say, "The main implication of our study is that type 2 diabetes is a growing public health problem for Asian Americans that requires urgent attention.
In some Asian cultures, Dr. Yeh noted, routine doctor visits are not the norm, and that could be one factor in Asian Americans' higher diabetes rate.
