Background: Recent changes in nutrition trends may lead to health issues. In particular, the unhealthy eating habits of young adults suggest that future generations may be at risk. Therefore, the importance and necessity of nutrition literacy is becoming increasingly apparent.
Purpose: The purpose of this study was to create a Turkish version of a short nutrition literacy (S-NutLit-Tr) scale for young adults developed by Vrinten et al (2023).
Methods: This research involved 115 young adults from Istanbul Gelişim University, who were selected through convenience sampling, a non-probability sampling method. After the original S-NutLit scale was translated into Turkish, the validity and reliability of the determined factor structure were tested on 115 young adults. Internal consistency was examined with the Cronbach Alpha coefficient. Confirmatory factor analysis was employed to validate the two sub-scale structures. Finally, measurement invariance was tested concerning participants' gender, aiming to ascertain whether the scale captured equivalent characteristics across different groups.
Results: As a result of the reliability analysis conducted with the scale of S-NutLit-Tr, the Cronbach Alpha coefficient was obtained as 0.86 for the scale of S-NutLit-Tr. Additionally, it was found to be 0.84 and 0.77 for the "information skills" and "expert skills" sub-scales, respectively. Accordingly, the scale of S-NutLit-Tr was found to be reliable. To examine the two sub-scale factor structures of the S-NutLit-Tr scale, fit indices were examined: χ/df (1.246), GFI (0.923), IFI (0.975), TLI (0.967), CFI (0.974), RMSEA (0.046), and SRMR (0.055) and it was observed that the indices were within acceptable limits. In the analysis results obtained through the multi-group confirmatory factor analysis for measurement invariance, it was observed that the ∆CFI and ∆TLI values across all indices were less than or equal to 0.01. Consequently, it was observed that the item-factor structure, factor loadings, variances, covariances, and error variances of the scale were equivalent for both male and female young adults.
Conclusion: The study found that the scale of S-NutLit-Tr for young adults was a valid and reliable measurement tool in Turkish culture.

Background: Smartwatches are increasingly popular for physical activity and health promotion. However, ongoing validation studies on commercial smartwatches are still needed to ensure their accuracy in assessing daily activity levels, which is important for both promoting activity-related health behaviors and serving research purposes.
Objective: This study aimed to evaluate the accuracy of a popular smartwatch, the Huawei Watch GT2, in measuring step count (SC), total daily activity energy expenditure (TDAEE), and total sleep time (TST) during daily activities among Chinese adults, and test whether there are population differences.

Background: Sleep-wake patterns are important behavioral biomarkers for patients with serious mental illness (SMI), providing insight into their well-being. The gold standard for monitoring sleep is polysomnography (PSG), which requires a sleep lab facility; however, advances in wearable sensor technology allow for real-world sleep-wake monitoring.
Objective: The goal of this study was to develop a PSG-validated sleep algorithm using accelerometer (ACC) and electrocardiogram (ECG) data from a wearable patch to accurately quantify sleep in a real-world setting.

Long-term training enables professional athletes to develop concentrated and efficient neural network organizations for specific tasks. This study used functional near-infrared spectroscopy to investigate task performance, brain functional characteristics, and their relationships in footballers during sport-specific motor-cognitive processes. Twenty-four footballers (athlete group, with 18 remaining of good signal quality) and 20 non-footballers (control group, with 16 remaining) completed four tasks: a single task (trigger buttons corresponding to the appearance direction of teammates with kicking actions), an N-back direction task, a dual task, and an N-back digit task.

Introduction: Obesity is a growing public health issue, especially among young adults, with long-term management strategies still under debate. This prospective study compares the effects of caloric restriction and isocaloric diets with different macronutrient distributions on body composition and anthropometric parameters in obese women during a 12-week weight loss program, aiming to identify the most effective dietary strategies for managing obesity-related health outcomes.
Methods: A certified clinical nutritionist assigned specific diets over a 12-week period to 150 participants, distributed as follows: hypocaloric diets-low-energy diet (LED, 31 subjects) and very low-energy diet (VLED, 13 subjects); isocaloric diets with macronutrient distribution-low-carbohydrate diet (LCD, 48 subjects), ketogenic diet (KD, 23 subjects), and high-protein diet (HPD, 24 subjects); and isocaloric diet without macronutrient distribution-time-restricted eating (TRE, 11 subjects).
