Adolescent chronic unpredictable stress leads to increased anxiety and attention deficit/hyperactivity-like symptoms in adulthood. Psychopharmacology (Berl) 2022; 239:3779-3791.

Abstract
BACKGROUND Early-life adversities during development (e.g., child abuse and neglect) are linked to multiple behavioral and cognitive dysfunctions, such as attention deficit/hyperactivity disorder (ADHD) and anxiety disorders, which have high comorbidity. However, the impact of adversities during adolescence, a crucial period in early life for these disorders, is understudied. Using a chronic unpredictable stress (CUS) model in rats, we investigated whether adversities in adolescence could lead to increased anxiety and ADHD-like symptoms in adulthood. METHODS Mid- to late-adolescent (5-7-week-old) male and female Sprague-Dawley rats underwent a mild CUS procedure for 2 weeks. Various stressors were applied in an unpredictable way. Rats of both sexes were then trained with a 2-choice reaction time (2-CRT) task during adulthood, which are designed to detect ADHD-like symptoms, including increased impulsivity and lapse of attention. In addition, an open field test was conducted to examine if CUS resulted in a persistent increase in anxiety-like behavior during adulthood. RESULTS Both male and female rats with CUS exposure travelled shorter distances in the open field and spent less time in the center zone, indicating increased anxiety. In the 2-CRT task, rats of both sexes with CUS exposure showed increased impulsivity. Augmented lapses of attention were observed in female but not male rats. CONCLUSION Chronic unpredictable stress during adolescence increases anxiety and leads to ADHD-like symptoms in both male and female rats in adulthood. The deficits are more severe in females than in males. These observations support that adversities during adolescence persistently increase anxiety, which is comorbid with attention deficits.

Abstract
ABSTRACT Smartphone addiction (SPA) affects an increasing number of college students, but it remains poorly understood. This study aimed to explore the psychological mechanism of the decrease in cognitive control ability from cognitive psychology in students with SPA.The smartphone addition tendency scale (MPATS) was used to identify 64 undergraduates with SPA (MPATS > 45) and 64 sex- and age-matched controls (MPATS < 30).The 2 groups were well matched for age and sex distribution. The RT of the SPA group under the conflict state was 628.2±59.2 ms vs 549.4 ± 44.2 ms under the consistent state (P < .005). The RT of the control group under the conflict state was 707.5 ± 66.4 vs 582.0 ± 39.4 ms under the consistent state (P < .005). Under the conflict state, errors made by the SPA group were 8.7 ± 5.4, and that of the control group was 6.6 ± 3.7 (P < .05). The reaction delay of the SPA group was 25.6 ± 49.2 vs 110.0 ± 41.8 ms (P < .05).Correlation analysis showed a clear positive correlation between SPA and the number of mistakes in the conflict state of the Stroop task.

Wang R, Martin CD, Lei AL, Hausknecht KA, Ishiwari K, Oubraim S, Wang AL, Richards JB, Haj-Dahmane S, Shen RY. Moderate prenatal ethanol exposure leads to attention deficits in both male and female rats. Alcohol Clin Exp Res 2021; 45:1122-1135. [PMID: 33730380 DOI: 10.1111/acer.14599] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Revised: 02/22/2021] [Accepted: 03/09/2021] [Indexed: 01/25/2023]
Abstract
BACKGROUND Attention deficits caused by prenatal ethanol (EtOH) exposure (PE) are a prevalent condition in fetal alcohol spectrum disorders (FASDs). Importantly, the deficits are observed in individuals with FASD who have normal IQs and show no dysmorphic facial features caused by heavy PE. These observations suggest that even moderate PE could lead to attention deficits. This possibility was investigated in the present study using a rat model. METHODS Pregnant Sprague Dawley rats were administered EtOH (3 g/kg/day) or vehicle via intragastric gavage on gestational days 8 to 20. The blood EtOH concentration (BEC) in EtOH-treated rats was 87.7 ± 1.2 mg/dl (1 h after the gavage), similar to the BECs reported in other moderate PE studies in rodents. Moderate PE did not produce teratogenic effects on birthweight or litter size. The adult offspring underwent a 2-choice reaction time task. RESULTS Moderate PE led to augmented action impulsivity in both sexes, indicated by more rapid response initiation and more premature responses. Deficits were more marked in males than in females. No greater lapses of attention, assessed by incorrect or relatively slow responses, were observed in rats of either sex with moderate PE. In addition, no deficits in learning or motor function were detected after moderate PE. Interestingly, rats with moderate PE completed more trials than controls. CONCLUSIONS Our results confirm that moderate PE leads to attention deficits in both sexes, which is demonstrated by greater action impulsivity, but not more lapses of attention. This effect differs from that of heavy PE, as shown in our previous study, which is manifested as impaired action impulsivity and lapses of attention in both sexes.

Mattar L, Farran N, Abi Kharma J, Zeeni N. Movie violence acutely affects food choices in young adults. Eat Behav 2019; 33:7-12. [PMID: 30771596 DOI: 10.1016/j.eatbeh.2019.02.002] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2018] [Revised: 02/01/2019] [Accepted: 02/07/2019] [Indexed: 11/24/2022]
Abstract
BACKGROUND Extensive research has been conducted to investigate the effects of media violence on attitudes, behaviors, and cardiovascular health; however, only few studies have examined its effect on appetite, eating behavior and food preferences. Little attention has been given to understand how movie genre manipulates the physiology and the eating behavior of individuals. The present study aimed at investigating the acute effect of violence content in movies on appetite perception, heart rate and blood pressure, along with food preferences and intake in young individuals. METHODS Participants (n = 84) were randomly assigned to either watch a violent movie or a non-violent narrative movie. Measurements including anthropometry, heart rate, blood pressure and grip strength were taken and appetite as well as stress perception were assessed. Subjects were then provided with an individual snack tray containing various items to be consumed ad libitum. RESULTS Post intervention, the experimental group (EG) had a higher consumption of fatty (t (82) = 2.28, p = 0.025, d = 1.52) and salty (t (82) = 2.61, p = 0.01, d = 0.71) food items compared to the control group (CG). Out of the 42 participants in the EG 62% consumed >2 fatty items and 71.4% consumed >2 salty food items. No significant difference in the consumption of sugary items was observed between the two groups. CONCLUSION Movie violence affects eating behavior and may promote weight gain.
