RESUMO:

Research aimed at assessing the food intake of visually impaired people is still scarce. Most studies about this group of people focus on identifying their nutritional status and diet-related difficulties, and when assessing dietary intake of these individuals, they do not employ specific methods that are valid for the visually impaired. Therefore, the development of strategies for assessing food intake that meet the specificities of a visually impaired person will contribute to health promotion and actions for disease prevention. These alternatives will also provide more autonomy when it comes to self-care related to health and nutrition within this population. Thus, the objective of the present research was to develop and validate a protocol for recording a food diary with photos taken by visually impaired people using smartphones. This development and validation study was carried out in three stages. In the first one, a technique for taking photos of food by visually impaired people using smartphones was established, as well as the register of protocols for execution. The second one comprehended the visually impaired people’s photographic recordings of three standardized meals (breakfast, lunch/dinner and snack), following the protocols developed for the study. In the third one, for protocol validation purposes, there was an assessment - done by a panel of specialists (nutritionists and photographers) - of the photographs regarding focus and angle in order to identify types and quantity of food/preparations in a five-point Likert Scale. The nutritionists also did the estimated food diary based on the observation of the photos which was compared to the researchers’. The Content Validity Index (CVI) was used to assess the consonance amongst the specialists. Five protocols were tested; two remained for being considered feasible by people who cannot see. The sample was comprised of 40 visually impaired people, the majority being blind (77,5%), male (67,5%), and adult (90%). The identification of food types shows consonance amongst the professionals, regardless of the protocol for framing CVI=0,87 in the protocol “cell at 45º” and CVI=0,9, in the “cell at 90º), focus (CVI=0,86 and CVI=0,9) and angle (CVI=0,9 and CVI=0,88) in all meals. From the analysis of the food register estimated by the experts, it was difficult to detail two of the 13 evaluated foods, namely, chicken and juice during drunk with lunch with a frequency of 45% and 50%, respectively (protocol “cell at 45º”) and 20% and 55% in the protocol “cell in 90º. The agreement to estimate the amount of food was better for French rolls (CVI=1.00 in the protocol “cell at 45º” and CVI=0.95 in the “cell at 90º”), coffee with milk (CVI=0.80 “cell at 45º” and CVI=0.7, at “cell at 90º”), and boxed grape juice (CVI=1.00 in both protocols). It is concluded, therefore, that the protocols developed allow the qualitative assessment of the diet of people with visual impairment, indicating the need for other adjacent strategies to improve the quantitative assessment, done by the professional, to be forwarded along with the photographs.
