Diabetes rates soar in Louisiana


Free abstract

MedWire News: The prevalence of diabetes has dramatically increased over the past decade in both men and women and in all races of the population served by Louisiana State University Health Care Services Division (LSUHCSD) hospitals, US researchers report.

Louisiana has the fourth highest prevalence of diabetes in the USA but, until now, the trend of diabetes prevalence in Louisiana has never been investigated, say the authors.

As reported in the journal Diabetes Research and Clinical Practice, Gang Hu (Pennington Biomedical Research Center, Los Angeles, USA) and team examined data from 969,609 patients aged 20 years or older, who received medical care from the LSUHCSD hospital system between 2000 and 2009.

The study revealed that the age-standardized prevalence of total diabetes increased by 36.2%, from 10.5% to 14.3%.

The authors observed a greater rise in prevalence among women (from 11.5% to 15.0%) than among men (from 8.9% to 13.3%).

They also found rise in prevalence differed according to race, increasing from 8.9% to 13.1% in White Americans, from 11.7% to 15.8% in African Americans, and from 8.2% to 10.4% in Americans of other races.

The researchers say their findings support those of the National Health and Nutrition Examination Survey, which showed that African Americans have a relatively high prevalence of diabetes compared with White Americans.

"Diagnosed diabetes remains twice higher in non-Hispanic Blacks than in non-Hispanic Whites and Louisiana has the second largest proportion of African Americans (32.5%) in the US," write the authors.

They say the results of their study warrants a greater focus in future health education and health promotion on preventing and controlling diabetes and its related factors in this population.
