Friend circle more predictive of your health than Fitbit

To get a better reading on your overall and wellness, you should be better off looking at the strength and structure of your circle of friends, says a study.

"What we found was the structure provides a significant improvement in predictability of states of an individual over just using the data derived from wearables, like the number of steps or heart rate," said the Nitesh V. Chawla, a of Indian origin from in the US.

For the study, participants wore to capture behaviour data -- such as steps, sleep, heart rate and activity level and completed surveys and self-assessments about their feelings of stress, happiness and positivity.

The research team then analysed the data, using machine learning, alongside an individual's characteristics, including degree, centrality, clustering coefficient and number of triangles.

The study showed a strong correlation between structures, heart rate, number of steps and level of activity.

According to the researchers, social network structure provided significant improvement in predicting one's and compared to just looking at health behaviour data from the alone.

For example, when social network structure is combined with the data derived from wearables, the model achieved a 65 per cent improvement in predicting happiness, 54 per cent improvement in predicting one's self-assessed health prediction, 55 per cent improvement in predicting positive attitude, and 38 per cent improvement in predicting success.

"This study asserts that without social network information, we only have an incomplete view of an individual's state, and to be fully predictive or to be able to derive interventions, it is critical to be aware of the social network structural features as well," Chawla said.
