    • "Other methods for MIB such as food frequency questionnaires and diet diaries are inaccurate due to subjects tending to underreport and miscalculate food consumption [9]. Thus, new approaches for objective and accurate assessment of free-living food intake patterns in humans are necessary for monitoring of eating behavior [10]. "

    ABSTRACT: Objective monitoring of food intake and ingestive behavior in a free-living environment remains an open problem that has significant implications in study and treatment of obesity and eating disorders. In this paper, a novel wearable sensor system (automatic ingestion monitor, AIM) is presented for objective monitoring of ingestive behavior in free living. The proposed device integrates three sensor modalities that wirelessly interface to a smartphone: a jaw motion sensor, a hand gesture sensor, and an accelerometer. A novel sensor fusion and pattern recognition method was developed for subject-independent food intake recognition. The device and the methodology were validated with data collected from 12 subjects wearing AIM during the course of 24 h in which both the daily activities and the food intake of the subjects were not restricted in any way. Results showed that the system was able to detect food intake with an average accuracy of 89.8%, which suggests that AIM can potentially be used as an instrument to monitor ingestive behavior in free-living individuals.

    • "The FFQ is suitable to assess the long-term eating behaviour over time, up to one year, providing general information about food intake (Thompson et al., 2010). The 24HR is often used to estimate usual food intake for 24 hours, but a single day evaluation gives reduced dietary habits (Dodd et al., 2006). "

    ABSTRACT: Children and adolescents learn about healthy eating habits at school and they know what these healthy concepts are but reality shows they do not take on action the practice based on these concepts (Ransley et al., 2010; Valente, Padez, Mourao, Rosado, & Moreira, 2010(Valente, Padez, Mourao, Rosado, & Moreira, 2010). Largely because of this, there is an exponential increase of prevalence of overweight/obesity in children and young people (Lobstein, Baur, & Uauy, 2004; Valente et al., 2010). In order to contribute for changing this current pattern, an educational programme called “Planning Health in School” (PHS) was designed, implemented and evaluated for the expected positive changes on eating behaviours among adolescents. This PHS programme integrated healthy eating and active living issues with adolescents’ participation and their motivation for healthier behaviours. The PHS program was implemented during a complete academic year with grade 6 adolescents of 10 to 14 years old. It started with an initial diagnosis and followed with the implementation of a set of eight learning activities and the monitoring of the process with several assessment tools. To evaluate the dietary evolution among adolescents, a 3-day food records tool was used to assess their daily food intake. In this study we describe the methodological approach used with the food records (FRs) and the achieved adherence among a group of adolescents during the implementation of the PHS program.

    • "Compared to other health behavior domains, technological assessment development has been relatively slower for dietary behavior assessment (Thompson et al., 2010) and is used primarily to facilitate direct observation of eating. The remote food photography method (RFPM) (Martin et al., 2009) represents one important technological advance in this area. "
