    Are hedonic hunger and health-related quality of life associated with obesity in adolescents?
    (Frontiers Media Sa, 2025) Koc, Bilge Meral; Kenger, Emre Batuhan; Yuksel, Ezgi Arslan; Karahan, Tugce Ozlu
    The purpose of the study is to find out the relationship between obesity, hedonic hunger and health-related quality of life (HRQoL). The questionnaire containing items on the sociodemographic characteristics, anthropometric measurements and nutritional habits of individuals (n = 902), the Children's Power of Food Scale and the KIDSCREEN-10 were used to determine the hedonic hunger and the HRQoL score. Hedonic hunger and HRQoL were evaluated according to the categories, frequency of consumption of sugary drinks and fast food. The females were found to have hedonic hunger more than the males (p < 0.05). Body mass index z-score categories of the adolescents showed that the obese eat more hedonically compared to the underweight and the normal-weight (p < 0.05), and this difference was not observed in the HRQoL scores (p > 0.05). There was a negative correlation between the hedonic hunger status and the HRQoL scores (R = -0.342, p = 0.000). The consumption of sugary drinks and fast food was associated with hedonic hunger and HRQoL scores in certain groups. Hedonic hunger is associated with obesity; hedonic hunger and quality of life are important factors associated with unhealthy food and drink intake.

    Complementary feeding practices and nutritional status in infants living in Turkey: Iowa infant feeding attitude scale and complementary feeding index
    (Wiley, 2025) Koc, Bilge Meral; Karahan, Tugce Ozlu; Yuksel, Ezgi Arslan; Garipoglu, Gokcen
    Although complementary feeding (CF) and maternal attitudes towards infant feeding are known to affect the nutritional status of infants during the neonatal period, studies in this field remain limited. The present study aimed to determine CF practices for infants aged 6-12 months who live in Turkey and maternal attitudes towards infant feeding. In addition, the effects of CF practices and maternal attitudes on the nutritional status of infants were examined. This study included 720 infants, of whom 289 were aged 6-8 months and 431 were aged 9-12 months. CF status was assessed using the CF index (CFI), and maternal attitudes towards infant feeding were measured using the Iowa infant feeding attitude scale (IIFAS). The weight and length measurements of infants were categorized using z-scores. Infants with weight-for-age z-score (WAZ) and weight-for-length z-score (WLZ) of less than -2 standard deviation were categorized as malnourished. Mothers of malnourished infants were found to have lower CFI and IIFAS scores (p < 0.05). Consistency of fruit feeding and complementary foods in the first 3 days of CF was associated with WAZ. The mothers' level of knowledge about CF and appropriate CF practices significantly affects the nutritional status of infants. The tools used in the present study to monitor CF practices should be incorporated into public health programmes.

    Planet-friendly plates: the effect of a plant-based diet on sustainable eating behavior in a sample of Turkish adults
    (Wiley, 2025) Kenger, Emre Batuhan; Karahan, Tugce Ozlu; Koc, Bilge Meral
    Background: In addition to the health effects of plant-based diets, their impact on the environment is becoming increasingly important. This study was conducted to assess the impact of adherence to a plant-based diet on sustainable eating behaviors. Materials and methods: This cross-sectional study was conducted on 2122 Turkish adults, 73% female and 27% male. The plant-based diet index (PDI), healthy plant-based diet index (hPDI) and unhealthy plant-based diet index (uPDI) were obtained from a validated semi-quantitative food frequency questionnaire (FFQ). After the index scores were calculated, the sample was divided into tertiles for each index. The sustainable eating behaviors of the participants were determined with the 'Behaviors Scale towards Sustainable Nutrition'. Results: The PDI and hPDI levels of female participants were found to be higher than those of male participants. Factors such as age, exercise and educational status were also found to affect adherence to a plant-based diet. In regression models, PDI (Model 1; beta: 0.413, Model 2; beta: 0.369, Model 3; beta: 0.367) and hPDI (Model 1; beta: 0.462, Model 2; beta: 0.366, Model 3; beta: 0. 351) scores had a positive effect on sustainable eating behavior scores, whereas uPDI (Model 1; beta: -0.496, Model 2; beta: -0.471, Model 3; beta: -0.459) scores had a negative effect (P < 0.001). Conclusion: Our findings suggest that individuals with higher adherence to overall plant-based and healthy plant-based diets exhibit more sustainable eating behaviors. Promoting healthy plant-based diets presents a promising approach to advancing sustainable nutrition, and mitigating environmental challenges. (c) 2024 Society of Chemical Industry.
