Weight Loss Experiences Differ for Minority Groups With T2DM

WEDNESDAY, July 24, 2019 -- Daily self-weighing uptake is considerable among minority subgroups with type 2 diabetes and is associated with year 1 weight loss among African-Americans, according to a study published online July 24 in Obesity.

Delia Smith West, Ph.D., from the University of South Carolina in Columbia, and colleagues examined weight loss at one, four, and eight years among 2,361 adults with obesity and type 2 diabetes randomly assigned to an intervention in the Action for Health in Diabetes (Look AHEAD) program. The authors examined treatment engagement variables and self-reported weight control behaviors among racial/ethnic and sex subgroups.

The researchers found that weight losses averaged ≥5 percent in year 1 among all subgroups, but all experienced regain; non-Hispanic white participants and minority women had sustained losses ≥5 percent at year 8. In year 1, session attendance was high (≥86 percent) and exceeded protocol-specified minimum levels into year 8. Stronger associations were seen for individual session attendance with weight loss among Hispanic and African-American participants compared with non-Hispanic white participants at both four and eight years. In all subgroups, daily self-weighing uptake was considerable; among African-American men and women, it was a prominent factor associated with year 1 weight loss. Among African-American women, greater meal replacement use was strongly associated with poorer one-year weight loss.

"These data markedly expand what is known about the weight loss experiences of minority men and women with diabetes, particularly minority men, and provide insights for intervention design," the authors write.

Many companies from the pharmaceutical and nutrition industry have made contributions to Look AHEAD.
