In adults, diabetes, hypertension and being overweight or obese increase the risk of cardiovascular
disease and several types of cancer. These risks also contribute to non-fatal diseases such as arthritis
and loss of vision due to diabetic retinopathy. Once considered a problem only in high-income
countries, obesity is on the rise in low- and middle-income countries. The prevalence of hypertension
is highest in some low-income countries, whereas public health interventions have reduced its
prevalence in many high-income countries.
