This article aims to reveal the knowledge, attitudes and behaviors of housewives living in Turkiye about food waste and sustainable nutrition. This study was conducted with 90 housewives between the ages of 25-65 from Turkey using the survey method. According to the research results; 24% of the participants stated that they waste food, while 53% stated that they do it sometimes. A significant positive correlation was found between education level and red meat and meat products, milk and dairy products and egg waste (p<0.05). Sustainable nutrition knowledge scores of the participants were found to be insufficient, with an average of 22.54 ± 3.80. A positive correlation was found between the amount of protein and zinc intake and the level of sustainable nutrition knowledge (p=0,027, r=0,233 and p=0,033, r=0,225). A significant and positive relationship was found between the scores of the participants in the scale of sustainable nutrition and healthy eating behaviors and their age (p=0,040, r=0,220). It has been determined that the knowledge levels of housewives about sustainable nutrition are deficient and insufficient. The issues of food waste and sustainable nutrition gain importance in terms of raising awareness and taking precautions for today and future generations, both economically and socioculturally.

Purpose This study aims to identify the dietary patterns of two groups of subjects (with and without COVID-19), and to assess the relationship of findings with the prognosis of COVID-19 and metabolic risk parameters. Design/methodology/approach This study included 100 individuals in the age range of 19–65 years. The medical history, and data on biochemical, hematological and inflammatory indicators were retrieved from the files. A questionnaire for the 24-h food record and the food intake frequency was administered in face-to-face interviews, and dietary patterns of subjects were assessed. Findings In individuals with COVID-19, the hip circumference, the waist-hip ratio and the body fat percentage were significantly higher (p < 0.05), and the muscle mass percentage was significantly lower (p < 0.05). Mediterranean diet adherence screener (MEDAS), dietary approaches to stop hypertension (DASH) and healthy eating ındex-2015 (HEI-2015) scores were low in the two groups. A linear correlation of DASH scores was found with the muscle mass percentage (p = 0.046) and a significant inverse correlation of with the body fat percentage (p = 0.006). HEI-2015 scores were significantly and negatively correlated with body weight, body mass index, waist circumference, hip circumference and neck circumference (p < 0.05). Every one-unit increase in MEDAS, DASH and HEI-2015 scores caused reductions in C-reactive protein levels at different magnitudes. Troponin-I was significantly and negatively correlated with fruit intake (p = 0.044), a component of a Mediterranean diet and with HEI-2015 total scores (p = 0.032). Research limitations/implications The limitation of this study includes the small sample size and the lack of dietary interventions. Another limitation is the use of the food recall method for the assessment of dietary patterns. This way assessments were performed based on participants’ memory and statements. Practical implications Following a healthy diet pattern can help reduce the metabolic risks of COVİD-19 disease. Originality/value Despite these limitations, this study is valuable because, to the best of the authors’ knowledge, it is the first study demonstrating the association of dietary patterns with disease prognosis and metabolic risks concerning COVID-19. This study suggests that dietary patterns during the COVID-19 process may be associated with several metabolic risks and inflammatory biomarkers.

Background: Coronavirus disease 2019 emerged in China in December 2019 as a disease spreading from person to person by rapid droplet transmission, and which eventually evolved into a pandemic. Aim: This study aims to examine the psychosocial state, nutritional awareness, and physical activity level of municipal employees who provided services under changing working conditions during the coronavirus disease 2019 pandemic. Methods: A total of 220 employees working in two different municipalities in Istanbul were included in this study during March and April of 2021. For data collection, a questionnaire form was used. The form consisted of questions about the demographics and nutritional awareness of individuals, the Coronavirus-19 Phobia Scale, and the International Physical Activity Questionnaire (short form). Results: The mean total coronaphobia score was 51.08 ± 14.47 with the mean score for women being significantly higher than that for men ( p < 0.05). The mean score obtained by the responses of participants to questions about nutritional awareness during the pandemic was significantly higher than the mean score referring to the period before the pandemic. The examination of the physical activity level of employees revealed that 62.4% of the men and 60% of the women were physically inactive during the pandemic. Conclusion: It was found that the coronaphobia scores of municipal employees during the coronavirus disease 2019 pandemic were at an average level, their nutritional awareness levels increased in general compared to the pre-pandemic period, and municipal employees were mostly inactive physically during the pandemic.
