I don’t know where you got that from.
A 2014 survey on Native Hawaiians/Pacific Islanders (NHPI) revealed that Native Hawaiian/Pacific Islander sub-populations had higher obesity rates than both Asian Americans and white Americans. In 2014, Samoans were 5.6 times more likely to be obese as compared to the overall Asian American population.Mar 26, 2020
As Orange Crush pointed out, you're confusing a state population with an ethnic group.
I lived on the Big Island of Hawaii for ten years. The vast majority of the current population on the Big Island is of Chinese, Filipino, Japanese, and Portuguese descent. That's because those ethnic groups were brought in over the years to work on the plantations, and then eventually acquired their own properties and jobs. Most of these people are relatively short and slim. We white people from the mainland were definitely in the minority.
There were relatively few people of native Hawaiian descent living there.
