Abstract

This study was conducted to determine the effects of fructo-oligosaccharide (FOS) inulin on anxiety symptoms in college students. Forty million adults in the United States suffer from anxiety. Previous studies have viewed gut microbiota and its potential link to anxiety in both humans and mice. However, no previous studies focused on the effect of FOS inulin on college students. Fourteen subjects received 4.9 g per day of FOS inulin as the treatment (TX) or no supplement as the control (CON) for 28 days. Both the TX and CON groups were given the Generalized Anxiety Disorder 7-Item Scale (GAD-7) on days 1 and 28. Both groups were also given a 3-day food log at the beginning of the experiment and otherwise maintained their regular diet. Results showed a statistically significant decrease in median GAD-7 scores in both groups (P = .017, r = .637 and P = .042, r = .587 for the TX and CON groups, respectively). However, when comparing the GAD-7 scores between groups, no statistically significant results were found. FOS inulin supplementation did not alleviate anxiety symptoms in college students participating in this study.

Depressive Symptoms and Smoking Cessation Among Adolescents and Young Adults Who Smoke: A Prospective Cohort Study.

PURPOSE: This study examined the bidirectional prospective associations between depressive symptoms and smoking cessation among adolescent and young adults who smoke. METHODS: Data on 1,151 participants aged &#x2264;25 years who smoke and receive peer-led quitline counseling in Hong Kong (2016-2022) were analyzed. Exposures included baseline depressive symptoms and smoking cessation (self-reported 7-day abstinence) at 1, 3, and 6 months; Outcome measures included smoking cessation at 1, 3, and 6 months and depressive symptoms at 6 months. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale, with a score &#x2265;16 indicating at risk for depression. RESULTS: More severe baseline depressive symptoms were associated with lower odds of smoking cessation at 1, 3, and 6 months, which reversely was associated with lower depressive symptoms at 6 months (all p < .05). Similarly, being at risk for depression at baseline was associated with lower odds of smoking cessation at 1 (adjusted odds ratio [aOR] .66, 95% confidential interval [CI] .47-.93) and 3 months (aOR .71, 95% CI .52-.97). Conversely, smoking cessation at 1 (aOR .40, 95% CI .23-.69), 3 (aOR .58, 95% CI .37-.92), and 6 months (aOR .44, 95% CI .29-.69) was associated with lower odds of at risk for depression at 6 months. DISCUSSION: More severe depressive symptoms were prospectively associated with lower odds of smoking cessation, while smoking cessation was associated with lower depressive symptoms and risk for depression. Integrated interventions simultaneously addressing psychological needs and smoking are warranted, when delivered in smoking cessation programs or embedded within mental health services for youth who smoke.

Eating Experiences During Cancer Treatment in Adolescents and Young Adults: A Systematic Literature Review and Meta-Synthesis.

Adolescents and young adults (AYAs) aged 15-39 with cancer face distinct challenges during treatment, with eating consistently emerging as one of the most distressing and underrecognized concerns. At a critical life stage, AYAs must navigate illness-related consequences that profoundly affect well-being. Eating reflects these broader challenges and is identified as a key issue requiring health care attention. To address this, we synthesized evidence on AYAs' eating experiences and well-being during mealtime-related activities to inform health care practice. Qualitative and mixed-method studies were identified through searches across CINAHL, Embase, PubMed, Scopus, and Web of Science for studies published up to May 2025, supplemented by snowball searches. Of 3214 records, 74 full-text articles were reviewed, and 18 met the inclusion criteria. These represented 302 AYAs, 73 relatives, and 88 health care professionals. Studies were analyzed using Joanna Briggs Institute review methods and GRADE-CERQual to support clinical interpretability. The meta-synthesis identified one core theme: "Eating as an embodied struggle and act of agency," with three subthemes: (a) living through physical and sensory disruption, (b) carrying the weight of new emotions and shifting relations, and (c) finding ways through gaps in support. Eating emerged as a disrupted, emotionally charged, yet agentic act requiring sensitive, individualized approaches. Thirteen evidence-informed recommendations were developed to guide clinical application. These emphasize early nutritional screening, dietetic support, flexible meal options, respectful family involvement, and psychosocially attuned care. Future research should codevelop and evaluate tailored interventions that address AYAs' embodied, emotional, and social needs to improve eating-related quality of life during cancer treatment.

"Abrazos, no Balazos": Intensity of Risk for Exposure to Violence and Armed Conflict Trajectories for Adolescents and Young Adults in M&#xe9;xico 2018-2024.

PURPOSE: "Abrazos, no balazos" (Hugs, not gunshots) is the approach to violence used by the Federal Mexican government from 2018 to 2024. This study identifies distinct conceptually useful latent class growth trajectories in the annual intensity of risk for exposure to events and fatalities from violence against civilians and battles for adolescents and young adults (AYAs) in M&#xe9;xico from 2018 to 2024. METHODS: Data are from the Armed Conflict Location and Event Data project. Latent class growth analyses were conducted with four longitudinal dependent variables assessed in seven sequential years (2018-2024). RESULTS: In most of the Mexican states, AYAs experienced low intensity-flat trajectories (p >.096) in the annual intensity of risk for exposure to events and fatalities from violence against civilians and battles. AYAs who lived in states with extremely, markedly, or moderately elevated 2018 intensities of risk for exposure to violence experienced decreasing trajectories (p =.000). One latent class with a mildly elevated-increasing trajectory (p =.000) in the annual intensity of risk for exposure to violence was identified for each of the four longitudinal dependent variables. DISCUSSION: During the time that the Federal Mexican government used the "Abrazos, no balazos" approach, AYAs in the majority of the states in M&#xe9;xico had intensity of risk for exposure to violence and armed conflict trajectories that were consistent with the goals of primary and secondary violence prevention. Violence prevention efforts should be augmented in states with unfavorable trajectories.
