Mudanças nas condutas de saúde e o seu efeito na insatisfação com peso corporal em adolescentes

Objective: As a popular social networking site, Facebook may assist in promoting health behaviours and delivering interventions. However, women rarely use social media for health-related purposes. This study aimed to identify factors influencing women's intentions to use Facebook to gain healthrelated support or information. Method: Using an online survey, data were collected from 159 adult females (Mean age = 26.81 years). Two hierarchical regressions were performed (Outcomes: health-related emotional support-seeking intentions on Facebook; health-relatedinformation-seeking intentions on Facebook). Predictors were age, past information/support-seeking on Facebook, time spent on Facebook per day (Step 1), health concern, appearance concern (Step 2), health locus of control (LOC; Step 3) and Theory of Planned Behaviour (TPB) variables (Step 4). Results: As hypothesised, the TPB constructs significantly predicted intention to use Facebook for health information and support. For information-seeking intention, TPB variables explained an additional 18.3% of the variance over and above that explained in previous steps of the model. Significant contributors were past information-seeking, attitude towards seeking health-related information on Facebook, and subjective norm. For support-seeking intention, TPB variables explained an additional 20.2% of variance. Significant contributors were attitude towards seeking health-related support on Facebook, past support-seeking, and powerful others LOC. Both final models accounted for 56.5% of the variance in information/support-seeking intentions. Conclusions: The TPB constructs effectively predict intentions to seek health information/support on Facebook in women. To increase women's engagement with Facebook for health information and support-seeking purposes, previous behaviours, attitudes, perceived social pressures, and locus of control warrant consideration.
