Would supermarket vouchers encourage you to do more exercise? How about sprinting tracks marked out on pavements? These are just two of the latest ideas in NHS England's Healthy New Towns initiative to put good health at the centre of urban design and planning.

Municipal leaders are in a unique position to influence the health of their citizens, the King's Fund think-tank argued this week. Action is certainly needed. Sadiq Khan, London's mayor, on Wednesday vowed to tackle the UK capital's gross health inequalities. 

More than half of the world's population now lives in cities, which are leading the way in public health initiatives, from New York's calorie-count laws to London's ultra-low emissions zone. Planning is fundamental. Climate, cultural differences, resources and political conditions mean interventions have to be tailored to different countries, and local government everywhere can play a greater role, as highlighted in the World Health Organization's Healthy Cities programme. 

Crusading leaders are a galvanising force. Michael Bloomberg's tenure as NY mayor saw action on smoking and trans fats, and he is still funding campaigns for soda taxes. That particular fight received another fillip this week as Singapore extracted a pledge from "Big Soda" to lower sugar content in their products.

Watch out for the FT’s interview with Mr Bloomberg on this subject next week.

Final thought

Making a song and dance about public health Bollywood movies are sometimes decried for their — albeit dazzling — escapism. But the big box office draw at the moment? Toilet: A Love Story. The film is one example of the industry taking on a serious subject. More than half of Indians lack access to a bathroom. Serious public health messages can also be fun. (The Guardian)
