A Quasi-Experimental Intervention Protocol to Characterize the Factors that Influence the Acceptance of New Foods by Infants: Mothers' Diet and Weaning Method. Dastatuz Project

Background: Children usually refuse to eat and taste fruits and vegetables; and turning unhealthy eating habits around is an important social challenge in industrialized countries. The Dastatuz project aims to study children food neophobia and to enhance fruit and vegetable acceptance. Methods: A quasi-experimental, multicentre, controlled and prospective intervention study is proposed, in which early factors influencing new food acceptance will be studied. Mothers in the third trimester of pregnancy (n = 144) and their infants will be the study population. Experimental groups will be established based on mothers ' fruit and vegetable intake (standard or high intake) and weaning method (baby lead weaning vs spoon feeding). The project will assess the possible impact of maternal diet and complementary feeding on infants eating behaviour until 18 months of age. Outcome measures will comprise maternal diet and psychological features during pregnancy and breast-feeding (validated questionnaires). Compositional and physicochemical analysis of milk during breastfeeding will also be carried out. During weaning, until 18 months of age, children's diet will be assessed with 24 h recalls and acceptance of new fruits and vegetables will be studied using video recording. Discussion: If the intervention is effective, this research work would have a high potential to be transferred to future public health programs or nutrition guidelines, as a feasible solution to achieve a higher intake of fruits and vegetables among children.This study is supported by the Government of the Basque Country (2019111080

Knowledge about COVID-19 and vaccine acceptability among priority groups defined for vaccination: A cross-sectional study in Araba/Alava, Spain, before the vaccination against SARS-CoV-2

Background: The acceptability of COVID-19 vaccine varies depending on the time, place, type of vaccine and information available at the time. Knowledge of attitudes and practices towards COVID-19 among the population at high risk of developing the disease would help to tailor the strategy to improve adherence to vaccination recommendations. Aim: To analyze the willingness, knowledge and risk perception of patients and health care workers (HCW) to get the vaccines against SARS-CoV-2. Methods: Cross-sectional survey in Araba/alava province (Spain). Subjects who met the criteria for the influenza vaccination in 2019 and HCWS from the Basque Public Health Service were included. The participants answered a questionnaire on the knowledge, attitudes and practices towards COVID-19 before starting vaccination against SARS-CoV-2. The intention to vaccinate was compared using the chi-squared test. Results: 316 HCWs and 389 patients responded to the survey. Around 90% of the patients and 80% of HCW would accept vaccination in all scenarios according to the questionnaire (p < 0.001). Only 3-12% hesitated about the COVID-19 vaccines. Compared to 40-70% of patients, 60-80% of HCWs perceived a high risk of COVID-19 (p < 0.001). Statistically significant differences were found in 10 of the 17 questions regarding the mechanism of transmission and symptoms. Conclusion: HCWs had a better knowledge and risk perception of COVID-19 than the surveyed patients. They had a higher proportion of hesitancy to get COVID-19 vaccine, probably related to doubts about the effectiveness of the new vaccines and the scientific evidence.Funding for the study was provided by the Caja Vital Foundation
