Family vs. individual profiles in a health portal: strengths and weaknesses

Obesity is a concern worldwide with an increasing proportion of people overweight or obese. Research has focused on preventive programs with numerous health behaviour change interventions (e.g. Hardeman et al., 2000 and Noar et al., 2007), and the development of technologies promoting healthy living and supporting behaviour change (e.g. Consolvo et al., 2008 and Mattila et al., 2008). Interventions and well-being applications are typically based on psychological models and behavioural theories. They aim to deliver effective health communication and to provide support and encouragement to impact people’s behaviour.
