Aetna joins a long list of companies that have integrated wearables as part of their corporate wellness program. Earlier this year, Vitality, a lifestyle and wellness programs provider, announced a scheme where workers are able to purchase a $350 Apple Watch for $25 provided that they meet their exercise goals. Qantas Assure lets you choose between an Apple Watch and Qantas points if you purchase their "Qantas Assure Health Insurance Policy." Insurance startup Oscar Health offered free MisFit wearables and rewards for staying in shape. In June this year, Fitbit announced the launch of its new corporate wellness service, building on its existing relationships with Fortune 500 companies, over 70 of which have reportedly adopted their programs.

The effectiveness of wearables on health and fitness, however, has come into question recently. A study investigating people who were aiming to lose weight found that those who wore fitness trackers lost less weight than those without. The Apple Watch 2 was also lacked certain popular fitness and health functionalities, although the company is reportedly working to fix this gap.

UPDATE: This story originally stated Oscar Health also subsidized the purchase of an Apple Watch. It was Qantas Assure. The story has been updated to reflect this.
