Preventive behaviors of COVID-19 in the Iranian adult population during the pandemic: Integrated effect of the health belief model and the planned behavior intention using causal path analysis.

Background: This study aimed to investigate the integration of the health belief model (HBM) and the theory of intention to plan preventive behavior for COVID-19 during the pandemic. Methods: In a cross-sectional study, a sample of 480 adult participants from different outpatient clinics were recruited in the study. The participant responded by self-report; the health belief model (HBM) scale, preventive behavior scale, subjective norms scale, the intention of planned behavior scale, and perceived control behavior scale were measured. The hypothesized causal path models were examined using SEM analysis. Results: The HBM had significant effects on perceived behavior control (ß=0.60, P=0.001), the intended preventive behavior (ß=0.32, P=0.001), and subjective norm (ß=0.53, P=0.001). Subsequently, the intention of preventive behavior (ß==0.39, P=0.001) and subjective norms (ß=0.27, P=0.001) significantly affected the performance of preventive behaviors. The estimated fitting criteria showed that the hypothesized model fits relatively well. Conclusion: The health belief model with the integration of subjective norms, perceived control behavior and mediation by the intention of planned behavior in a pathway relationship explains well the preventive behavior of COVID-19. The findings present a deeper understanding of how integrating HBM and intended planned behavior enhances people's preventive behavior against COVID-19.

Impulse control behaviors and apathy commonly co-occur in de novo Parkinson's disease and predict the incidence of levodopa-induced dyskinesia.

OBJECTIVE: Impulse control behaviors (ICBs) and apathy are believed to represent opposite motivational expressions of the same behavioral spectrum involving hypo- and hyperdopaminergic status, but this has been recently debated. Our study aims to estimate the co-occurrence of ICBs and apathy in early Parkinson's disease (PD) and to determine whether this complex neuropsychiatric condition is an important marker of PD prognoses. METHODS: Neuropsychiatric symptoms, clinical data, neuroimaging results, and demographic data from de novo PD patients were obtained from the Parkinson's Progression Markers Initiative, a prospective, multicenter, observational cohort. The clinical characteristics of ICBs co-occurring with apathy and their prevalence were analyzed. We compared the prognoses of the different groups during the 8-year follow-up. Multivariate Cox regression analysis was conducted to predict the development of levodopa-induced dyskinesia (LID) using baseline neuropsychiatric symptoms. RESULTS: A total of 422 PD patients and 195 healthy controls (HCs) were included. In brief, 87 (20.6 %) de novo PD patients and 37 (19.0 %) HCs had ICBs at baseline. Among them, 23 (26.4 %) de novo PD patients and 3 (8.1 %) HCs had clinical symptoms of both ICBs and apathy. The ICBs and apathy group had more severe non-motor symptoms than the isolated ICBs group. Cox regression analysis demonstrated that the co-occurrence of ICBs and apathy was a risk factor for LID development (HR 2.229, 95 % CI 1.209 to 4.110, p = 0.010). CONCLUSIONS: Co-occurrence of ICBs and apathy is common in patients with early PD and may help to identify the risk of LID development.

Effects of the source of information and knowledge of dengue fever on the mosquito control behavior of residents of border areas of Yunnan, China.

BACKGROUND: Strengthening the mosquito control measures undertaken by residents of an area where dengue fever is present can significantly decrease the spread of this disease. The aim of this study was to explore the effects of the source of information and knowledge of dengue fever on the mosquito control behavior of residents of areas at high risk of this disease to determine effective ways of enhancing this behavior. METHODS: A survey was conducted via face-to-face interviews or questionnaires between March and May 2021 in three regions of the province of Yunnan, China. The survey included basic information about the respondents, the source(s) of their dengue fever information, the level of their dengue fever knowledge, and the measures they had implemented to control mosquitoes. Principal component analysis was used to extract the main components of the sources of information. Correlation analysis and structural equation analysis were used to explore the impact of the sources of information and residents' dengue fever knowledge on their mosquito control behavior. RESULTS: Publicity achieved through mass media, including official WeChat accounts, magazines/newspapers, poster leaflets, television/radio and the Internet, had a direct effect on dengue fever knowledge and mosquito control behavior, and indirectly affected mosquito control behavior through dengue fever knowledge. Organized publicity campaigns, including information provided by medical staff and through community publicity, had a direct effect on dengue fever knowledge and indirectly affected mosquito control behavior through dengue fever knowledge. The residents' level of dengue fever knowledge had a significant, positive, direct effect on their mosquito control behavior. CONCLUSIONS: Mosquito control is an important measure for the prevention and control of outbreaks of dengue fever. An effective source of information can improve the level of dengue fever knowledge among residents and thus enhance their mosquito control behavior.

Breastfeeding and pumping as maladaptive weight control behaviors.

It is well recognized by the general public that breastfeeding expends calories. In our clinical practice, a number of postpartum women with a history of or a current eating disorder (ED) report using breastfeeding and/or pumping breast milk to influence their body shape and weight. This appears to be either a form of weight control behavior or, in some cases, a compensation for perceived overeating or binge eating. Breastfeeding and pumping have not generally been identified as maladaptive weight control behaviors, nor have they been a subject of research to date. We suggest that this practice should be investigated to determine how common it is, its potential role in maintaining EDs or contributing to relapse in the postpartum period, and to better understand other potential harms it may cause to both the mother and infant/child. PUBLIC SIGNIFICANCE: Breastfeeding and pumping may be used as maladaptive methods of weight control by women with EDs. This behavior is under-recognized in clinical practice and has received little research attention. We argue that maladaptive breastfeeding and pumping warrant further investigation, as the behaviors may play an important role in maintaining an ED or in contributing to relapse during the postpartum period and may also indirectly harm the infant/child.

Young Novice Drivers' Cognitive Distraction Detection: Comparing Support Vector Machines and Random Forest Model of Vehicle Control Behavior.

The use of mobile phones has become one of the major threats to road safety, especially in young novice drivers. To avoid crashes induced by distraction, adaptive distraction mitigation systems have been developed that can determine how to detect a driver's distraction state. A driving simulator experiment was conducted in this paper to better explore the relationship between drivers' cognitive distractions and traffic safety, and to better analyze the mechanism of distracting effects on young drivers during the driving process. A total of 36 participants were recruited and asked to complete an n-back memory task while following the lead vehicle. Drivers' vehicle control behavior was collected, and an ANOVA was conducted on both lateral driving performance and longitudinal driving performance. Indicators from three aspects, i.e., lateral indicators only, longitudinal indicators only, and combined lateral and longitudinal indicators, were inputted into both SVM and random forest models, respectively. Results demonstrated that the SVM model with parameter optimization outperformed the random forest model in all aspects, among which the genetic algorithm had the best parameter optimization effect. For both lateral and longitudinal indicators, the identification effect of lateral indicators was better than that of longitudinal indicators, probably because drivers are more inclined to control the vehicle in lateral operation when they were cognitively distracted. Overall, the comprehensive model built in this paper can effectively identify the distracted state of drivers and provide theoretical support for control strategies of driving distraction.

Direct and Indirect Paths between Parental Marital Conflict and Children's Sibling Conflict in Chinese Families.

Links between parental marital conflict and children's sibling conflict have been well examined; however, the underlying mechanism of this link needs to be further studied. This study investigated the mediating role of parental intervention styles (i.e. child-centered strategies, control strategies, and nonintervention strategies) and children's control behavior toward their sibling between parental marital conflict and children's sibling conflict. We recruited 689 Chinese children (53.7% girls) aged 8-13 years to participate in the study. Results indicated that parental marital conflict, control strategies, nonintervention strategies, and children's control behavior toward sibling were positively associated with sibling conflict among children. Child-centered strategies were negatively correlated with children's sibling conflict. Furthermore, control and nonintervention strategies of parents and control behavior of children toward sibling simultaneously partially mediated between parental marital and child-sibling conflict. The mediating role of child-centered strategies was not significant. These findings suggest that parental strategies of control and nonintervention and children's control behavior toward their sibling may increase the risk of sibling conflict among children after repeated exposure to parental marital conflict. In contrast, child-centered strategies may be a protective factor for children regarding sibling conflict. Current findings confirm the combined effects of parent and child behavior on child-sibling conflict. They also help parents deal with sibling conflict among their children and promote more positive relationships among siblings.

How prepartum appearance-related attitudes influence body image and weight-control behaviors of pregnant Japanese women across pregnancy: Latent growth curve modeling analyses.

A thin female physique is idealized in modernized societies, leading many pregnant women to experience body dissatisfaction and avoid weight gain, as pregnancy directs their body away from the sociocultural ideal of thinness. However, not all pregnant women report body dissatisfaction and/or weight-control behavior. We aimed to discern how prepartum weight-related attitudes-thin-ideal internalization, drive for thinness, and appearance comparison tendency-influence changes in negative attitudes toward a pregnant body, body image, and weight-control behavior across pregnancy. Data were longitudinally collected from 208 Japanese pregnant women (Mage = 27.0, SD = 1.74) across three pregnancy periods. Results indicated that overall, negative attitudes toward appearance change during pregnancy, weight-control behaviors, and restrained eating significantly changed across pregnancy. Moreover, those with higher prepartum thin-ideal internalization showed greater decreases in negative attitudes toward appearance change during pregnancy and greater increases in body dissatisfaction, whereas those with higher prepartum drive for thinness and appearance comparison tendency showed greater decreases in restrained eating across pregnancy. Our findings suggest that pregnant women with certain prepartum weight-related attitudes may experience an aggravation of body dissatisfaction while following dietary regimen during pregnancy. Thus, prevention programs may selectively help them reduce their negative body image during pregnancy.

Weight Perception and Weight Control Behavior among Florida High School Students.

Objective: Actions adopted by adolescents to control their weight are motivated by their body weight perception. In this study, we aimed to investigate the association between body weight perception and weight control behavior among Florida public high school students. Methods: We analyzed data from the 2015 Florida Youth Risk Behavior Survey (N = 3798). We used chi-square test to detect group differences among survey respondents and multivariate logistic regression to assess the association between weight perception and weight control behavior. Results: Most survey respondents adopted healthy actions such as exercise and diet, 75.3% and 55.0%, respectively, and few used unhealthy ones as weight control means, such as fasting, use of diet products, and purging, 15.6%, 7.3%, and 6.5% respectively. Compared to respondents who considered themselves as having the right weight, there were higher odds of engaging in healthy activities only in respondents who considered themselves as being overweight while there were higher odds of engaging in unhealthy actions in respondents perceiving themselves as underweight and in those viewing themselves as overweight. Conclusion: High school health education courses should include modules educating students on the importance of having accurate knowledge about body weight and adopting a healthy weight control behavior.

Early hyperdopaminergic state following sub-thalamic nucleus deep brain stimulation in Parkinson disease.

BACKGROUND: Hyperdopaminergic state (HS), especially impulse control behaviors (ICBs), are not rare in Parkinson's disease (PD). Controversial data regarding HS prevalence one year following sub-thalamic nucleus deep brain stimulation (STN-DBS) are reported. OBJECTIVE: Our objectives were to describe early postoperative HS (PoOHS) including ICBs, hypomania and psychotic symptoms during the first 3 months following STN-DBS (V1) and their prognosis at 1 year (V2). METHODS: This descriptive study included 24 PD patients treated successively with bilateral STN-DBS between 2017 and 2019. The primary endpoint was prevalence of PoOHS at V1 according to the Ardouin Scale of Behaviour in Parkinson's Disease. RESULTS: Prior to STN-DBS (V0), 25% patients had HS (only ICBs) whereas at V1 (during the 3 first months), 10 patients (41.7%) had one or several HS (P=0.22) (de novo in 29.2%): 7 (29.2%) ICBs, 4 (16.7%) hypomanic mood, 1 (4.7%) psychotic symptoms. At V2, all V0 and V1 HS had disappeared, while 1 patient (4.2%) presented de novo HS (P<0.01). No correlation was found between the occurrence of PoOHS at V1 and any V0 data. Higher levodopa equivalent dose of dopamine agonists at V1 was correlated with ICB at V1 (P=0.04). CONCLUSION: We found that early PoOHS are frequent in PD after STN-DBS, mostly de novo, with ICBs and hypomania being the most frequent. Despite a good prognosis of PoOHS at one year, our work emphasizes the importance of both a cautious adjustment of dopamine agonist doses and a close non-motor monitoring pre- and post-STN-DBS in PD.

Factors Associated With Unhealthy Weight Control Behaviors Among a Representative Sample of U.S. High School Students.

Adolescents often practice unhealthy behaviors to lose weight or keep from gaining weight. Centers for Disease Control and Prevention has conducted biennial Youth Risk Behavior Survey (YRBS) of various health risk behaviors since 1991 using U.S. representative samples of high school students and is therefore best for us to identify risk/preventive factors associated with unhealthy weight control behaviors (UWCB). We quantitatively assessed the association between various health risk behaviors with UWCB by gender using YRBS data. Due to the absence of UWCB items since 2015, we analyzed the latest (2013) data using binary multiple logistic regression. Among the 13,583 participants, 22.7% of girls and 10.1% of boys engaged in UWCB. Among girls and boys separately, the common significant factors included suicidal behaviors, alcohol drinking, misused prescription drug, feeling depressed, skipping breakfast, and attending physical education class. School nurses are suggested to have knowledge about the aforementioned risk factors and provide assessment, consultation, and education to help reduce UWCB.

Dopamine genetic risk score predicts impulse control behaviors in Parkinson's disease.

INTRODUCTION: Up to 40% of Parkinson's disease patients taking dopamine agonist medication develop impulse control behaviors which can have severe negative consequences. The current study aimed to utilize dopamine genetics to identify patients most at risk of developing these behaviors. METHODS: Demographic, clinical, and genetic data were obtained from the Parkinson's Progression Markers Initiative for de novo patients (n = 327), patients taking dopamine agonists (n = 146), and healthy controls (n = 160). Impulsive behaviors were identified using the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease. A dopamine genetic risk score was calculated for each patient according to polymorphisms in genes coding for dopamine D1, D2 and D3 receptors, and catechol-O-methyltransferase. A higher score reflected higher central dopamine neurotransmission. RESULTS: Patients on agonists with a low dopamine genetic risk score were over 18 times more likely to have an impulsive behavior compared to higher scores (p = 0.04). The 38% of patients taking agonists who had at least one impulsive behavior were more likely to be male and report higher Unified Parkinson's Disease Rating Scale I&II scores. With increasing time on dopamine agonists (range 92-2283 days, mean 798 ± 565 standard deviation), only patients with a high dopamine genetic risk score showed an increase in number of impulsive behaviors (p = 0.033). Predictive effects of the gene score were not present in de novo or healthy control. CONCLUSIONS: A dopamine genetic risk score can identify patients most at risk of developing impulsive behaviors on dopamine agonist medication and predict how these behaviors may worsen over time.

Body dissatisfaction and disordered eating are prevalent problems among U.S. young people from diverse socioeconomic backgrounds: Findings from the EAT 2010-2018 study.

PURPOSE: Body dissatisfaction and disordered eating are linked to adverse health consequences. Research describing socioeconomic patterns in the prevalence of these problems is important for informing the design of health services and efforts to improve health equity. METHODS: Population-based cohort study (EAT 2010-2018: Eating and Activity over Time) of socioeconomically and ethnically/racially diverse U.S. young people who completed surveys as adolescents in 2009-2010 (mean age = 14.5 years) and as emerging adults in 2018 (mean age = 22.0 years). Participants were recruited from 20 schools in Minneapolis-St. Paul, Minnesota. Household socioeconomic status was determined using adolescent report of parental education, employment, and public assistance benefits. Analyses were conducted using data from 1531 participants and regression models that accounted for repeated measures within individuals. RESULTS: Among females, high body dissatisfaction and unhealthy weight control behaviors (e.g., skipping meals) were more prevalent and regular use of lifestyle weight management behaviors (e.g., exercise) was less prevalent in the low SES group as compared to the middle and/or upper SES groups (p ≤ .010). Among males, thinness-oriented dieting, unhealthy weight control behaviors, and extreme weight control behaviors (e.g., taking diet pills) were all more prevalent in the low SES group as compared to the middle and/or upper SES groups (p ≤ .010). Few differences were observed across SES groups in models that adjusted for ethnic/racial identity and body mass index. CONCLUSIONS: There is a need for greater attention to the reach and relevance of efforts to prevent disordered eating and improve body satisfaction to ensure efforts benefit young people across SES groups.

Impact of behavioral side effects on the management of Parkinson patients treated with dopamine agonists.

Dopamine agonists are one of the main stay of treatment option for Parkinson disease (PD). Side effects that develop from their use are generally categorized into behavioral and non-behavioral. Behavioral side effects include: impulse control behavior disorder (ICD), psychosis and cognitive impairment. Non-behavioral side effects include: nausea/vomiting, "sleep attacks", leg swelling, weight gain and orthostasis. The aim of this study is to evaluate the clinicians' response to PD patients who developed behavioral side effects from dopamine agonists, in comparison to those patients who developed only non-behavioral side effects. We performed a retrospective chart review of all patients diagnosed with PD over a two year period. Among 313 patients who were on a dopamine agonist, 156 reported side effects. Sixty-five patients reported behavioral (with or without non-behavioral) side effects, while 91 experienced only non-behavioral side effects. Forty-nine out of the 65 patients (75.3%) who experienced behavioral side effects had their dopamine agonist dose decreased compared to 53 out of 91patients (58.2%) who experienced only non-behavioral side effects (Chi square = 4.92, p < 0.05). Patients with behavioral side effects were 3 times more likely have their dose decreased (OR = 3.3; 95%CI = 1.442-7.551; P = 0.005). However, neither taper speed nor the occurrence of dopamine agonist withdrawal syndrome (DAWS) differed between the two groups. Amongst PD patients treated with dopamine agonists, the presence of behavioral side effects independently increased the chance of dopamine agonist dose reduction. Prospective studies are needed to confirm these findings.

A Study on the Correlation Between Media Usage Frequency and Audiences' Risk Perception, Emotion and Behavior.

Whether risk events can be effectively controlled and mitigated is largely influenced by people's perceptions of risk events and their behavioral cooperation. Therefore, this study used a web-based questionnaire (N = 306) to investigate the specific factors influencing people's risk perceptions and behaviors, and included a test for the difference in the effect of positive and negative emotions of the audiences. The results show that the overall model has good explanatory power (R 2 = 61%) for the behavioral variables, and (1) how people's use of different media (especially TV and online media) significantly influenced their positive and negative emotions; (2) how people's frequency of TV use significantly influenced their risk susceptibility and how online media use significantly influenced their risk severity (with some differences in people's perceptions of efficacy between different media); (3) how people's sense of efficacy for risky events is the strongest predictor of their risk control behavior; and (4) that there are different mediating effects of different emotions and risk severity and sense of efficacy between the frequency of media use and risk control behavior.

Associations Between Weight Perception, Unhealthy Weight Control Behavior, and Suicidal Ideation and Planning Among Korean Adolescents: A National Cross-Sectional Secondary Analysis.

PURPOSE: This study aimed to investigate the associations between weight perception, unhealthy weight control behavior, and suicidal ideation and planning and identify the role of unhealthy weight control behavior as a mediator in these associations among Korean adolescents. DESIGN AND METHODS: This national cross-sectional secondary study used data from the 2015-2017 Korea Youth Risk Behavior Web-Based Surveys, with a final sample of 96,285 adolescents who tried to manage their weight in the 30 days prior to the surveys. A multivariate logistic regression was conducted. RESULTS: Both adolescent groups who perceived themselves to be underweight or overweight were significantly linked to a greater likelihood of suicidal ideation and planning (COR, 95% CI = 1.249, 1.141-1.367; COR, 95% CI = 1.339, 1.282-1.399) respectively. While adolescents with perceptions of being underweight are associated with suicidal ideation and planning through the suppression effect of unhealthy weight control behavior (Pathway A: OR, 95% CI = 0.628, 0.587-0.671), adolescents with perceptions of being overweight are linked with the same through the mediation effect (Pathway A: OR, 95% CI = 1.195, 1.141-1.251). CONCLUSIONS: Adolescents with perceptions of being overweight are highly likely to have unhealthy weight control behavior that can be linked to the possibility of suicidal ideation and planning, while adolescents with perceptions of being underweight are comparatively less likely to engage in such behavior. PRACTICE IMPLICATIONS: It is necessary to identify the status of weight perception among adolescents and closely monitor the unhealthy weight control behavior to prevent suicidal ideation and planning.

Maternal Comfort with Lesbian, Gay, and Bisexual People and Their Children's Drinking, Smoking, and Disordered Weight Control Behaviors as Adults.

Purpose: We investigated associations between maternal comfort with lesbian, gay, and bisexual (LGB) people during the participant's adolescence and their health indicators in adulthood. Methods: Data came from a prospective cohort, Growing Up Today Study (N = 7476), limited to men and women who provided information during their adulthood about recent binge drinking, cigarette smoking, or disordered weight control behaviors (DWCB) and whose mothers provided information during the participant's adolescence about her comfort with LGB people. Results: Increased maternal comfort with LGB people was associated with increased engagement in health indicators for heterosexual but not sexual minority adults (binge drinking, cigarette smoking, and DWCB for women; binge drinking for men). No association existed between maternal comfort with LGB people and binge drinking or cigarette smoking for sexual minority women, and binge drinking for sexual minority men. This resulted in statistically smaller differences across sexual orientation in cigarette smoking for women when their mothers were highly comfortable with LGB people compared with those whose mothers were uncomfortable with LGB people. There were no differences in binge drinking (women and men) and DWCB (women only) across sexual orientation when mothers were highly comfortable with LGB people. Conclusion: Maternal comfort with LGB people is associated with certain sexual orientation-related disparities in health indicators through adulthood, due to increased engagement in health indicators by heterosexual adults. Exposure to sexual orientation stigma in adolescence, measured as maternal comfort with LGB people, possibly drives well-known differences in drinking, smoking, and DWCB during adulthood between heterosexual and sexual minority adults.

Smoking as a weight control strategy of Serbian adolescents.

OBJECTIVES: The objective is to determine association of age, gender, BMI, body image (body satisfaction, body appearance), depression, unhealthy weight control behaviors with smoking among Serbian adolescents and specifically association of these variables with smoking for weight control among adolescent smokers. METHODS: This is a secondary analysis of data collected from 2763 students aged 13-15 years old (49.9% boys; 50.1% girls) obtained through cross-sectional Health Behavior in School-aged Children Survey conducted in Serbia in 2018 and analyzed using multivariable logistic regression. RESULTS: In Serbia, 12.9% adolescents 13-15 years old smoke and 6.6% smoke for weight control, while this practice was present among 48.8% of the smokers. Higher odds of smoking were found among adolescents who perceive themselves thin and good looking, while these two factors didn't play role for the smoking for weight control among smokers. Depression and unhealthy weight control behavior other than smoking significantly predicted smoking and smoking for weight control. Gender was not associated with smoking in adolescents, but among adolescent smokers, boys had two times higher chance compared to girls to report smoking for weight control. CONCLUSIONS: Findings call for incorporating and strengthening interventions for adolescents' weight control management and mental health as part of smoking prevention and cessation programs.

Encapsulation of MnS Nanocrystals into N, S-Co-doped Carbon as Anode Material for Full Cell Sodium-Ion Capacitors.

Sodium-ion capacitors (SICs) have received increasing interest for grid stationary energy storage application due to their affordability, high power, and energy densities. The major challenge for SICs is to overcome the kinetics imbalance between faradaic anode and non-faradaic cathode. To boost the Na+ reaction kinetics, the present work demonstrated a high-rate MnS-based anode by embedding the MnS nanocrystals into the N, S-co-doped carbon matrix (MnS@NSC). Benefiting from the fast pseudocapacitive Na+ storage behavior, the resulting composite exhibits extraordinary rate capability (205.6 mAh g-1 at 10 A g-1) and outstanding cycling stability without notable degradation after 2000 cycles. A prototype SIC was demonstrated using MnS@NSC anode and N-doped porous carbon (NC) cathode; the obtained hybrid SIC device can display a high energy density of 139.8 Wh kg-1 and high power density of 11,500 W kg-1, as well as excellent cyclability with 84.5% capacitance retention after 3000 cycles. The superior electrochemical performance is contributed to downsizing of MnS and encapsulation of conductive N, S-co-doped carbon matrix, which not only promote the Na+ and electrons transport, but also buffer the volume variations and maintain the structure integrity during Na+ insertion/extraction, enabling its comparable fast reaction kinetics and cyclability with NC cathode.

The association between Food and Alcohol Disturbance (FAD), race, and ethnic identity belonging.

PURPOSE: A growing body of literature has established that food and alcohol disturbance (FAD: decreasing one's caloric intake in preparation for alcohol consumption) is a specific health risk that endangers health and wellbeing. Recent research on trends in FAD has revealed ethno-racial disparities. A sociological analysis is helpful to center race and examine the role of ethnic identity in reproducing health disparities. The current study is guided by theories of socialization into ideal body types by race. METHODS: Study uses data from a cross-sectional survey conducted among college students. The sample includes White and Black American college students, ages 18-25, and uses ordinal logistic regression to test for the impact of race and ethnic identity on engagement in FAD using the Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale (CEBRACS). RESULTS: FAD prevalence was lower among Black Americans than among White Americans in the sample. Results from ordered logistic regression models indicate that stronger ethnic ties reduce likelihood of FAD among Black Americans but have the opposite effect among White Americans. This modification effect provides evidence that ethnic identity belonging protects against FAD for Black Americans but acts as a risk factor for FAD among White Americans. CONCLUSIONS: Findings shed light on the documented racial disparities in FAD and weight control behavior more broadly. Ethnic identity modifies the relationship between race and FAD in our sample. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.

Effect of Using Mobile Phones on Driver's Control Behavior Based on Naturalistic Driving Data.

Distracted driving behaviors are closely related to crash risk, with the use of mobile phones during driving being one of the leading causes of accidents. This paper attempts to investigate the impact of cell phone use while driving on drivers' control behaviors. Given the limitation of driving simulators in an unnatural setting, a sample of 134 cases related to cell phone use during driving were extracted from Shanghai naturalistic driving study data, which provided massive unobtrusive data to observe actual driving process. The process of using mobile phones was categorized into five operations, including dialing, answering, talking and listening, hanging up, and viewing information. Based on the concept of moving time window, the variation of the intensity of control activity, the sensitivity of control operation, and the stability of control state in each operation were analyzed. The empirical results show strong correlation between distracted operations and driving control behavior. The findings contribute to a better understanding of drivers' natural behavior changes with using mobiles, and can provide useful information for transport safety management.
