This study aims to evaluate the reliability, quality, and readability of ChatGPT's responses to nutrition-related questions asked by women with PCOS. Frequently asked nutrition-related questions from women with PCOS were reviewed in both Turkish and English. The reliability and quality of the answers were independently evaluated by 2 authors and a panel of 10 expert dietitians, using modified DISCERN and global quality score. Additionally, the readability of the answers was calculated using frequently used readability formulas. The mean modified DISCERN scores for English and Turkish versions were 27.6±0.87 and 27.2±0.87, respectively, indicating a fair level of reliability in the responses (16–31 points or 40%–79%). According to the global quality score, 100% of the responses in English and 90.9% of the responses in Turkish were rated as high quality. The readability of responses was classified as “difficult to read” with the readership levels assessed at college level and above for both English and Turkish. The correlation and regression analyses indicated no relationship between reliability, quality, and readability in English. However, a significant relationship was observed between quality and readability indexes in Turkish (<em>P</em> &lt; .05). Our results suggest that ChatGPT's responses to nutrition-related questions about PCOS are generally of high quality, but improvements in both reliability and readability are still necessary. Although ChatGPT can offer general information and guidance on nutrition for PCOS, it should not be considered a substitute for personalized medical advice from health care professionals for effective management of the syndrome.</div></div>","PeriodicalId":19245,"journal":{"name":"Nutrition Research","volume":"133 ","pages":"Pages 46-53"},"PeriodicalIF":3.4,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142824455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesized that higher intakes of ultra-processed foods (UPF) will be related to higher risk of depression and anxiety while an opposite association will be observed for unprocessed or minimally processed foods (MPF). Data come from a Lebanese cross-sectional study (n = 188 adults). The NOVA classification was adopted for evaluating the intakes of the 4 food groups: unprocessed or minimally processed foods (MPF); processed culinary ingredients (PCI); processed foods (PF) and ultra-processed foods (UPF). Associations between food group intakes in quartiles with depression and anxiety symptoms were analyzed using multivariable regression analyses adjusted for several confounders. Median energy intake was 2481.65 (2617.2) kcal/d, with 36.12% of Total Energy Intakes coming from MPF, 29.71% from PF, 25.25% from UPF, and 5.75% from PCI. Among participants, 33% and 27.7% had elevated depression and anxiety symptoms, respectively. Higher PF intake was associated with significantly lower odds of both depression and anxiety symptoms while a higher UPF intake was associated with higher odds of depression.

This study evaluated the agreement between bioelectrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA) in assessing body composition and its changes during a long-term lifestyle intervention in children and adolescents with obesity. We hypothesized that BIA is comparable to DXA in tracking longitudinal changes in body composition in this population. The study included 92 children and adolescents 5 to 17 years of age (mean 10.5 ± 2.9 years) classified as obese at the time of measurement (body mass index-standard deviation score ≥ 2 SD). From January 1, 2014, to December 31, 2017, they participated in a lifestyle intervention at Randers Regional Hospital. Body composition was assessed using BIA and DXA at baseline and follow-up (mean 20.5 ± 9.3 months). Bland–Altman plots, correlation- and concordance analyses were used to evaluate the agreement between methods. Bland–Altman plots demonstrated wide limits of agreement without significant bias for longitudinal changes in fat mass (FM), FM%, fat-free mass (FFM), and FFM% (0.39 kg (CI –0.14, 0.93), –0.39% (CI –1.06, 0.26), –0.21 kg (CI –0.73, 0.31), and 0.39% (CI –0.27, 1.05), respectively). Correlations between methods for changes in FM, FM%, FFM, and FFM% were 0.93, 0.83, 0.88, and 0.83, respectively. In cross-sectional assessments, BIA underestimated FM and FM% and overestimated FFM and FFM% compared to DXA. Conclusively, BIA effectively monitors longitudinal changes in body composition at a group level in a pediatric population with obesity.

We hypothesized that age, sex, race/ethnicity, diet, vitamin D, and body composition will be associated with gut integrity and inflammation. Socio-demographic variables were collected with a questionnaire. Measures included markers of gut integrity (Intestinal Fatty Acid Binding Protein; I-FABP), and inflammation (IL-17 and calprotectin) determined by ELISA in 24-h urine and serum; serum 25(OH)D concentration (commercial lab), BMI percentile, and diet (24-h recalls).

The current study expands on prior analyses to examine the cross-sectional associations between adult RS-assessed skin carotenoids and individual carotenoid species intakes and plasma concentrations, controlling for potential covariates.
