Scott Lear, a cardiovascular researcher at Simon Fraser University, argues that global heart health guidelines are heavily influenced by data from high-income countries. His review emphasizes that such recommendations, such as exercise duration and dietary intakes, fail to consider the diverse social, environmental, and economic factors that affect cardiovascular disease, particularly in low- and middle-income settings. Lear illustrates these disparities with comparisons between urban environments in wealthier nations and poor, polluted cities like New Delhi, underscoring the need for locally relevant health strategies utilizing evidence from global studies like PURE.
The world extends beyond high-income countries when we think about universal recommendations like 75 minutes of exercise each week or getting five servings of fruit and vegetables every day.
There's a stark contrast between a daily sidewalk stroll in Vancouver's West End and walking to work in New Delhi, the world's most polluted city.
We cannot assume that life is the same everywhere. The environments in which people live and the kind of work they do make a huge difference to their health.
The review examined the impact of social, environmental, and policy factors on cardiovascular disease globally using comprehensive data from the PURE study.
