Obesity in both women and men is regarded as one of the many factors that may contribute to impaired reproductive health. Obesity can be accompanied by several neuroendocrine and ovarian dysfunctions, including chronic oligo/anovulation, menstrual irregularities, subfertility, and the increased risk of pregnancy in women. Insulin resistance, elevated triglyceride and fatty acid levels, and the secretion of adipocytokines caused by the excessive accumulation of adipose tissue associated with obesity adversely affect reproductive functions. Alterations in sperm quality and motility and hormone levels related to a rise in body mass index (BMI) may predispose men to infertility. The mechanisms of action of obesity on male infertility include endocrinopathy, erectile dysfunction, epididymitis, increased leptin and adipocytes, increased aromatase, inflammatory cytokines secreted by fat tissue, and sperm DNA fragmentation. This study reports that an increased BMI may lead to low semen quality, poor sperm motility, and reduced fertilization rates in men as well as anovulation, pregnancy loss, diminished pregnancy, and low live birth rates in women. Having optimal weight with balanced nutrition enables one to maintain a continuity of reproductive health throughout the entire life cycle, which is extremely important in terms of having a healthy embryo, including pre-foetal life, in the continuity of pregnancy and having a live birth.

Revealing motivations in food choice and investigating the potential role of sustainable healthy eating behavior, ecological footprint awareness and food security in food choice are important points for a sustainable life. This study was conducted with 5285 adults aged 19–65 residing in Turkey to investigate their food choice motivations in terms of sustainable and healthy eating behavior, ecological footprint awareness, and the food insecurity perspective. In this context, the Food Choice Questionnaire, the Sustainable and Healthy Eating Behaviors Scale, the Awareness Scale for Reducing Ecological Footprint and the Household Food Insecurity Access Scale were used. Pearson correlation analysis was used to examine relationships between scales. The effects of sustainable and healthy eating behaviors, ecological footprint awareness, and household food insecurity on food choice motivations were examined via path analysis. A moderate positive (r = 0.47, p < 0.05) relationship was found between the participants’ awareness levels of sustainable and healthy eating behaviors and reducing the ecological footprint. A weak negative (r=-0.22, p < 0.05) relationship was found between their awareness levels of ecological footprint reduction and household food insecurity, and a weak negative (r=-0.16, p < 0.05) relationship was found between sustainable and healthy eating behaviors and household food insecurity. The explanatory power of ecological footprint awareness, sustainable and healthy eating behaviors, and household food insecurity for food choices was 27.2%. It was observed that ecological footprint awareness (β = 0.21, p < 0.05) and sustainable and healthy eating behaviors (β = 0.38, p < 0.05) significantly and positively affected food choices. The variables influencing food choices the most were sustainable and healthy eating behavior, ecological footprint awareness, and household food insecurity. Although there are various data in the literature on the multiple factors that determine food choices, a consensus on the effectiveness of these factors has yet to be reached. A comprehensive examination of this issue, including all the components, is needed.

The relationships between diet quality, malnutrition status and dietary intake and health problems such as frailty, sarcopenia, low physical function and depression, which are frequently observed in older individuals, are still unclear. This study aimed to investigate the associations between malnutrition, diet quality, and dietary intake and frailty, sarcopenia, low physical function, and depression in elderly individuals. The Edmonton Frailty Scale (EFS), Sarcopenia Rapid Screening Test (SARC-F), Katz Activities of Daily Living Scale (KATZ) for the Elderly, Geriatric Depression Scale (GDS), Mini Nutritional Assessment (MNA)-Short Form, and Mediterranean Diet Adherence Scales (MEDAS) were administered to all study participants (n = 695) to determine frailty, sarcopenia, physical status, depression status, nutritional status and adherence to the Mediterranean diet. The participants' dietary acid load was assessed via the potential renal acid load (PRAL) and net endogenous acid production (NEAP) indicators. Compared with men, women had significantly greater levels of frailty and sarcopenia (p < 0.05). Frailty and sarcopenia status were correlated with each other, and GDS scores increased significantly, whereas KATZ scores decreased as their severity increased (p < 0.05). MNA and MEDAS scores correlated with EFS (r = -0.508, p < 0.001; r = -0.084, p = 0.027, respectively), SARC-F (r = -0.358, p < 0.001; r = -0.126; p = 0.001, respectively), and GDS (r = -0.397, p < 0.001, r = -0,243, p < 0,001, respectively), whereas KATZ and MNA (r = 0,439) scores were found to be positively correlated with energy (r = 0,133) and protein (r = 0,119) intake (p < 0,05). As the PRAL score increased, the GDS (r = -0.082; p = 0.031), the SARC-F (r = -0.087; p = 0.022), and the EFS (r = -119, p = 0.002) decreased significantly. Each 1-unit increase in the MNA score caused decreases of 0.857, 0.431, and 1.201 units in the EFS, SARC-F, and GDS, respectively, and an increase of 0.190 units in the KATZ. Malnutrition status is positively associated with frailty, sarcopenia, low physical activity, and depression.

Background/Objectives: Increasing awareness of factors that put the population at high risk of frailty is essential to prevent frailty and minimize its adverse consequences. Methods: In this cross-sectional study, participants were over the age of 65 and living in nursing homes. The Edmonton Frailty Scale was used to determine frailty, the Sarcopenia Rapid Screening Test (SARC-F) was used to assess sarcopenia, and the Mini Nutritional Assessment (MNA) questionnaire and 7-day 24-h dietary recall were used to determine the nutritional status of the older adult population. Data were analyzed by SPSS 25.0 for Windows (Statistical Package for Social Sciences). Results: The frailty scale score of gender was statistically significant (p < 0.05). There was a statistically significant difference in sarcopenia status and malnutrition based on the distribution of the frailty status among the participants (p < 0.05). There was a statistically significant difference in vitamin C intake adequacy according to the distribution of frailty status among older adults (p < 0.05). There was a positive correlation between frailty status and sarcopenia (r = 0.773; p < 0.05). Frailty and nutritional status were significantly negatively correlated (r = −0.496; p < 0.05). There was a significant positive correlation between the sarcopenia status and malnutrition status of the participants (r = 0.489; p < 0.005). Conclusions: Older adults living in nursing homes are at risk for frailty syndrome, malnutrition, and sarcopenia. Evaluating older adults in terms of all these factors and implementing daily nutrition plans and support according to these results is of great importance for promoting a healthy life.

Aim: This study was aimed to determine the relationship between nutritional knowledge level and self-esteem in adult women with type 2 diabetes. Material and Method: The sample of this descriptive cross-sectional study consisted of 387 participants. Data were collected in an endocrinology outpatient clinic via face-to-face interviews. The data collection form consisted of a 'Personal Information Form', 'Nutrition Habits Section', 'Nutrition Knowledge Level and Food Preference Scale', 'Rosenberg Self-Esteem Scale'. Number and percentage were used in the SPSS package program. Results that were not normally distributed were evaluated according to non-parametric tests. Results: The mean age of the participants was 42.00±11.35 years and the educational level of 31.2% was primary school. The mean total score of the scales obtained by the participants was average. In the study, no relationship was found between basic nutrition knowledge level and food preference and self-esteem in adult women with type 2 diabetes. Conclusion: Basic nutrition knowledge and food preferences of women with Type 2 Diabetes were moderate and their self-esteem was adequate. It is important for health professionals to plan individual trainings by determining the nutritional knowledge levels and food preferences of women, and to ensure that diabetes control and self-esteem are increased in the effective management of diabetes and in the promotion of women's health.

Aims: Test anxiety/stress may influence eating behaviors and diet quality. The purpose of this study was to investigate the relationships between exam stress and eating attitudes, behaviors, and diet quality in young adults. Methods: This study was conducted with 557 young adults via a voluntary sampling method via online platforms (Facebook, Instagram, WhatsApp, etc.) between April and May 2025. The survey form used to collect data consisted of four sections: an introductory information form covering sociodemographic characteristics, the Westside Test Anxiety Scale, the Eating Attitudes Test (EAT-26), and the Mediterranean Diet Adherence Screener (MEDAS). Data analysis was performed with IBM SPSS Statistics 26.0 and AMOS 24. Independent samples t tests, one-way analysis of variance (ANOVA), Pearson correlation analysis and path analysis were used. Results: Most of the participants exhibited normal eating attitudes (74.3%) and moderate Mediterranean diet characteristics (57.6%). Compared with those with normal eating behaviors, those with abnormal eating behaviors had significantly lower MEDAS scores (6.2±2.13 vs. 6.9±2.36, p=0.003) and significantly higher Westside Test Anxiety Inventory scores (33.0±9.30 vs. 28.4±9.12, p
