The obesity epidemic is an increasing public health issue worldwide. In the Caribbean region, childhood obesity levels are higher than in the rest of the world and can be linked to developing many comorbidities. This narrative review aims to determine the factors contributing to the rise in childhood obesity in the Caribbean. A literature search included articles published between 2010 and 2023, written in English and allowed free access to the abstracts. Results show childhood obesity is a multifactorial disease that can be linked to many factors, such as physical inactivity, poor dietary habits, shortened sleep duration, family determinants, and nonmodifiable factors. A call for action is needed in the Caribbean to help curb the rise in childhood obesity.
