Given this, this paper aims at determining the magnitude and factors associated with stunting among 6–59 month old children in Ilubabor Zone, Southwest Ethiopia.\u0000\u0000\u0000Design/methodology/approach\u0000This paper opted for a descriptive study using an interviewer-administered questionnaire and anthropometric measurements of 617 children aged 6–59 months. A systematic random sampling technique was used to select the study participants. Data was analyzed using Statistical Package for Social Sciences (SPSS) version 25 and World Health Organization (WHO) Anthro software. Multivariate logistic regression analysis was used to identify independent predictors of stunting.\u0000\u0000\u0000Findings\u0000About 33.7% of children aged 6–59 months included in this study were stunted. The proportion of moderate and severe stunting among the stunted children was 26.4% and 7.3%, respectively. Large family size (AOR = 4.0; 95% confidence interval [CI]: 2.5, 6.4), low dietary diversity score (AOR = 7.8; 95% CI: 4.6, 13.0) and household food insecurity (AOR = 16.4; 95% CI: 10.0, 26.7) were independent predictors of stunting.\u0000\u0000\u0000Research limitations/implications\u0000Reporting and recall bias related to food groups consumed over the past seven days and seasonal variation may affect the findings related to factors associated with stunting.\u0000\u0000\u0000Practical implications\u0000Globally, it is estimated that nearly 165 million children under the age of five are stunted. Outcomes associated with stunting include increased risk of mortality, increased disease risk, developmental delays, diminished ability to learn and lower school achievement and reduced lifelong productivity. So, determining the level of stunting in a particular community is important to design strategies for curbing the contributing factors.\u0000\u0000\u0000Originality/value\u0000This study’s community-based design yields a representative sample of study subjects in the Hurumu district, which is valuable for intervention methods and actions.

The purpose of this study was to investigate whether drinking green tea can clinically improve psychiatric complications of COVID-19 infection.\u0000\u0000\u0000Design/methodology/approach\u0000This study included 40 patients with laboratory confirmed mild-to-moderate COVID-19 disorder in the current randomized open-label controlled trial. Patients were instructed to include three cups/day of green tea (intervention) or black tea (control) to their usual diet for four weeks immediately after diagnosis of the disease. At the study baseline and after the intervention, the enrolled patients’ fatigue, depression and anxiety were assessed by the Chalder Fatigue Scale, Beck Depression Inventory-Fast Screen and State-Trait Anxiety Inventory questionnaires.\u0000\u0000\u0000Findings\u0000A total of 19 COVID-19 cases in the intervention group (mean age = 52 years) and 14 cases (mean age = 50 years) in the control group completed the study.

A higher percent of Azeri adolescents were obese than their Kurd counterparts (p = 0.006). No association was found between individual factors and BAZ in each ethnic group. Considering home environment characteristics, in Kurd adolescents, the maternal occupational level was positively associated with BAZ (p = 0.02). With regard to school environmental features, accessibility of physical activity facilities in school was inversely associated with BAZ only in Kurds (p = 0.005).\u0000\u0000\u0000Originality/value\u0000To the best of the authors’ knowledge, this is the first study to investigate various environmental factors in association with adolescent’s overweight/obesity prevalence in different ethnical groups in northwest Iran.\u0000","PeriodicalId":19376,"journal":{"name":"Nutrition & Food Science","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2021-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48356397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
