The story of Saint Lucia in numbers
In 2024, about 34.8% of adults in Saint Lucia were living with obesity — about 1 in 3 adults, according to World Health Organization estimates (the likely range is 31.0% to 38.6%). That is roughly 50 thousand people aged 18 and over.
That is higher than the world average of 16.2%, and ranks 38th highest out of 199 countries. It is about level with the average for WHO’s Americas region (34.4%).
Back in 1980, the figure was 6.4%. Since then it has gone up by 28.4 percentage points — about 5.4 times the 1980 level. In people, that is a change from about 3,000 to 50 thousand adults, partly because the population itself changed.
Women are more likely to live with obesity than men: 47.8% compared with 21.2%.
Among children and teenagers aged 5 to 19, 19.1% were living with obesity in 2024, compared with 3.1% in 1980 — around 6,000 young people.
For context, 19.7% of adults had diabetes in 2022, 20.9% of adults did not get enough physical activity in 2022 and the food supply provided about 2,654 calories per person per day in 2023. These numbers don’t prove what causes obesity, but they help paint the picture.
