Does botulinum toxin affect psycho-social aspects in dystonia?

Dystonia is a movement disorder in which sustained muscle contractions give rise to abnormal postures or involuntary movements. It is a disabling and disfiguring disorder that affects activities of daily living and gives people a bizarre appearance often associated with psychological morbidity, embarrassment and social avoidance. Intramuscular injection of botulinum toxin (BoNT) is the most effective treatment for motor symptoms in focal dystonia, but little is known about its impact on the psycho-social dimension. The main aim of this study was to evaluate psycho-social changes in patients with focal dystonia after starting BoNT treatment using self-reported scales. The Beck Depression Inventory (BDI-II), the 36-Item Short Form Health Survey (SF-36), the Body Uneasiness Test (BUT), the State-Trait Anxiety Inventory (STAI) and the Visual Analogue Scale (VAS) assessing body self-image, satisfaction with physical aspects, social avoidance, self-reported depression, and self-distress were completed by 11 patients with dystonia and 9 patients with hyperhidrosis as a control group before BoNT (T0). VAS was then performed after four weeks (T1) to assess whether BoNT induced changes in the psychosocial dimension. Our results showed that only depressive symptoms and rumination about body defects improved in patients with dystonia after BoNT treatment, while improvement in self-distress and satisfaction with physical aspects was also found in hyperhidrosis. Individuals with hyperhidrosis experience poorer psychological well-being and suffer from higher levels of distress compared to dystonic patients. This suggests that individuals with this disabling condition are more vulnerable to social impact than dystonic patients.

Gender-specific social and environmental correlates of active travel to school in four European countries: the HBSC Study.

Introduction: Despite the health benefits, a large proportion of girls and boys in Europe do not travel to school actively. A better understanding of the correlates associated with this behavior could guide interventions. This study examines perceived social and environmental correlates of active travel to school (ACTS) from the 2017/18 Health Behavior in School-Aged Children (HBSC) survey in four European countries, with a special emphasis on gender differences (n = 22,023). Methods: Logistic regression was conducted to analyze associations between the perceived importance of each correlate and ACTS behavior for 11-, 13-, and 15-year-old girls and boys from Germany, Czechia, Poland, and Slovakia. All models were adjusted for age, family affluence, and meeting World Health Organization recommendations for moderate-to-vigorous physical activity. Results: Rates of ACTS significantly differed between girls and boys. In Czechia, 65% of girls and boys traveled to school actively, followed by Slovakia (61.4% girls and 58.4% boys), Poland (57.7% girls and 60.2% boys), and Germany (42.6% girls and 48.6% boys). Girls were less likely to actively travel to school compared to boys (odds ratio [OR]: 0.92, 95% confidence interval [CI]: 0.87-0.97). Increasing age (OR: 0.95, 95% CI: 0.93-0.97) and a greater distance to school index (OR: 0.89, 95% CI: 0.88-0.90) were both negatively associated with ACTS. The perceived importance of living closer to school and of road and neighborhood safety was positively associated with ACTS, with a stronger association in boys than in girls for neighborhood safety. On the contrary, the perceived importance of having people to walk with was negatively associated with ACTS, with a stronger association in girls (OR: 0.74, 95% CI: 0.65-0.84) than in boys (OR: 0.77, 95% CI: 0.66-0.88). Discussion: This study provides insights into perceived social and environmental correlates associated with ACTS behavior. Future research should include gender-specific perceptions and more in-depth investigations of correlates encouraging ACTS, especially considering social aspects, safety issues, and the structuring of the environment in different cultural settings.

Association between socio-ecological factors and leisure time physical activity (LTPA) among older adults in Sichuan, China: a structural equation modeling analysis.

BACKGROUND: Few studies examined socio-ecological factors and leisure time physical activities (LTPA) and rarely focused on self-regulation and social capital, which might play a significant role in impacting people's physical activity behavior. This study aimed to examine the direct and indirect effects of individual level (perceived benefits, perceived barriers, and self-efficacy), interpersonal level (self-regulation), social level (social capital), and environmental level factors (perceived physical environment) on LTPA among older adults. METHODS: A cross-sectional study was conducted in 737 older adults from Sichuan, China. Structural equation modeling (SEM) analysis was used to examine the associations of individual, interpersonal, social, and environmental level factors with LTPA. RESULTS: The mean age of all participants was 71.22 (range, 60-97), and 56.1% of them were women. The SEM results showed that individual level variables (ß = 0.32, ρ < 0.001), self-regulation (ß = 0.18, ρ < 0.001) and social capital (ß = 0.14, ρ < 0.001) could all directly affect LTPA while there was no significant association of perceived physical environment with LTPA. Self-regulation served as a bridge linking social capital and LTPA. Individual level variables contributed the largest total effect (0.32) on LTPA. Self-regulation and social capital had the same total effect (0.18) on LTPA. CONCLUSIONS: Factors on three levels were all significantly associated with LTPA. Interventions that incorporate individual, interpersonal, social factors may be considered to promote LTPA in older adults. Self-regulation should receive more attention in future interventions.

Prevalence and risk factors of food insecurity among Libyan migrant families in Australia.

BACKGROUND: The burden of food insecurity remains a public health challenge even in high income countries, such as Australia, and especially among culturally and linguistically diverse (CALD) communities. While research has been undertaken among several migrant communities in Australia, there is a knowledge gap about food security within some ethnic minorities such as migrants from the Middle East and North Africa (MENA). This study aims to determine the prevalence and correlates of food insecurity among Libyan migrant families in Australia. METHODS: A cross-sectional design utilising an online survey and convenience sampling was used to recruit 271 participants, each representing a family, who had migrated from Libya to Australia. Food security was measured using the single-item measure taken from the Australian Health Survey (AHS) and the 18-item measure from the United States Department of Agriculture Household Food Security Survey Module (USDA HFSSM). Multivariable logistic regression was used to identify independent correlates associated with food insecurity. RESULTS: Using the single-item measure, the prevalence of food insecurity was 13.7% whereas when the 18-item questionnaire was used, more than three out of five families (72.3%) reported being food insecure. In the multivariable logistic regression analysis for the single-item measure, those living alone or with others reported higher odds of being food insecure (AOR = 2.55, 95% CI 1.05, 6.21) compared to those living with their spouse, whereas higher annual income (≥AUD 40,000) was associated with lower odds of food insecurity (AOR = 0.30, 95% CI 0.11, 0.84). Higher annual income was also associated with lower odds of food insecurity (AOR = 0.49, 95% CI 0.25, 0.94) on the 18-item measure. On both single and 18-item measures, larger family size (AOR = 1.27, 95% CI 1.07, 1.49 and AOR = 1.21, 95% CI 1.01, 1.47 respectively) was associated with increased odds of food insecurity. CONCLUSION: This study provides evidence that food insecurity amongst Libyan migrants in Australia is a widespread problem and is associated with a number of sociodemographic and socio-economic factors. The findings of this study serve to contribute to the depth and breadth of food security research among vulnerable communities, in this instance Libyan migrant families.

The Relationship between Social Environmental Factors and Motor Performance in 3- to 12-Year-Old Typically Developing Children: A Systematic Review.

Motor performance during childhood is important for prosperity in life, and the social environment may contain potentially important and modifiable factors associated with motor performance. Therefore, the aim of this systematic review was to identify social environmental factors associated with motor performance in 3- to 12-year-old typically developing children. Four electronic databases were searched, which resulted in 31 included studies. The methodological quality was determined using the Quality of Prognosis Studies in Systematic Reviews tool. Most studies were conducted in 3-6-year-old children. In the home environment, parental beliefs in the importance of physical activity and parental behaviors matching these beliefs were related to better motor performance of children, although these relationships were often sex-dependent. The school and sports environments were investigated much less, but some preliminary evidence was found that being better liked by peers, attending a classroom with a smaller age range, having more interaction with the teacher and classmates, and having a higher educated teacher was related to better motor performance. Further research is required to further unravel the relationship between the social environment and motor skills, with a specific focus on 6-12-year-old children and environments outside of the home environment.

Psycho-social correlates of leisure-time physical activity (LTPA) among older adults: a multivariate analysis.

BACKGROUND: Still, a considerable number of older adults hardly meet the daily physical activity recommendation. The current study examined how the elderly's attitudinal and perceptional aspects were associated with their Leisure-Time Physical Activity (LTPA) participation in order to provide insight into the physical activity promotion. METHODS: Study used a total sample of 10,700 older adults aged 65+ drawn from the Health and Retirement Study (HRS) 2014-2015 in USA. Multiple questionnaire items were employed to assess older adults' attitudes and outlook across different life domains. LTPA participation was measured using two indicators-walking and sports/exercise. A technique of adjusted multivariate analysis was employed to examine the relationships between predictors and outcome variables. RESULTS: Results indicated that psychosocial indicators were significantly associated with older adults' LTPA: self-perception of ageing, self-efficacy, intrinsic motivation, spiritual engagement, perceived social tie and neighbourhood safety; while measures of perceived social relations and neighbourhood safety demonstrated different associations with walking and sports/exercise on its intensity. CONCLUSIONS: Health professionals should be well-informed about psychosocial roles, either as facilitators or constraints, in older adults' physical activity participation. Incorporation of psychosocial intervention into physical activity promotion can help older adults develop positive attitudes and inner strength linked to their health behaviour.

Social and Stylistic Correlates of Vocal Fry in a cappella Performances.

OBJECTIVE: To determine the social and stylistic correlates of vocal fry in a cappella performances. STUDY DESIGN: A matched-guise experiment was used to measure listener evaluations of fry and non-fry guises. METHODS: Four singers, two male and two female, sang "The Star-Spangled Banner" with onset vocal fry. These recordings were used to create the two guises: (i) an unmodified recording with onset vocal fry on vowel-initial words and (ii) a recording in which the fry had been removed. In total, 253 participants listened to the recordings and evaluated the singers' social and stylistic attributes along a Likert scale, e.g., how confident, sexy, and sincere each singer sounded. A factor analysis was used to conflate correlated variables, and mixed effects linear regression models (n = 1,012) were fitted to each lone or joint factor to determine whether vocal fry significantly influenced listeners' responses to the singers. RESULTS: Vocal fry significantly altered listener evaluations of the singers' sincerity/commitment, maturity/sophistication, naturalness, and confidence (P < 0.05). Unlike male singers, who were rated as significantly less sincere/committed with vocal fry, female singers were seen as more sincere/committed with vocal fry and younger listeners also found them less natural, suggesting vocal fry is associated with emotional intensity in female voices. Younger listeners perceived singers with fry as less mature/sophisticated, suggesting an association with youth. Finally, listeners with more musical training rated singers with fry as less confident, while less trained listeners did not exhibit this difference. CONCLUSIONS: Listeners are highly attuned to vocal fry in music but respond to it differently based upon their age, musical training, and the singer's sex. Vocal fry is evaluated more positively among younger, less musically trained listeners, and it is better received in women's voices, suggesting that the use of fry strategically targets a specific audience, i.e., younger and less trained listeners, who interpret fry as a marker of youth and emotional earnestness. These findings show that a single stylistic feature like vocal fry can be imbued with multiple meanings depending on the singer and audience, and its use can serve to include or exclude particular listener groups.

Depression Symptom Patterns and Social Correlates among Chinese Americans.

The aim of this study is to examine and compare the depression symptoms pattern and social correlates in three groups: foreign-born Chinese Americans, US-born Chinese Americans, and non-Hispanic whites. This study used data from the Collaborative Psychiatric Epidemiology Surveys (CPES). The study sample consists of 599 Chinese Americans (468 for the foreign-born and 121 for the US-born) and 4032 non-Hispanic whites. Factor analysis was used to examine the depression symptom patterns by each subgroup. Four depression symptoms dimensions were examined: negative affect, somatic symptoms, cognitive symptoms, and suicidality. Logistic regression was used to investigate the effects of sociodemographic (age, gender, marital status, and education), physical health condition, and social relational factors (supports from and conflict with family and friends) on specific types of depression symptoms separately for the three subgroups. The findings showed little differences in depression symptom patterns but clear variation in the social correlates to the four depression dimensions across the three ethnocultural groups, foreign-born Chinese Americans, US-born Chinese Americans, and non-Hispanic whites. Clinicians should take into account the sociocultural factors of patients when making diagnosis and suggesting treatments. In addition, psychiatrists, psychologists, or other mental health service providers should offer treatment and coping suggestions based on the specific symptom dimensions of patients, and patients' ethnocultural backgrounds.

Predictors of Physical Activity Levels in Community-Dwelling Older Adults: A Multivariate Approach Based on a Socio-Ecological Framework.

The purpose of this study was to explore cross-sectional relationships between self-reported physical activity (PA) and personal, social, and environmental factors in community-dwelling adults aged 50 years and older. Accounting for clustering by neighborhood, generalized estimating equations were used to examine associations between selected correlates and the Physical Activity Scale for the Elderly (PASE) score while adjusting for confounders. Data for 601 participants were analyzed: 79% female, 37% married, mean age 76.8 (± 8.7) years, mean PASE score 112.6 (± 64.8). Age, living in seniors' housing, using nursing/home care services, receiving encouragement to be active, and having benches available in the neighborhood were inversely associated with PASE. Self-efficacy, SF-12 score, PA barriers, social support, and the presence of trails showed positive associations. Several personal, social, and environmental factors associated with PA were identified. The inverse association between PA and living in seniors' housing units should be considered when developing PA programs for older adults.

Psychological and social correlates of doping attitudes among Italian athletes.

BACKGROUND: This study aims to identify the main psychological and social correlates of doping attitudes among Italian athletes. It is well recognized that athlete disposition and attitude towards doping is one of the factors responsible for doping behavior. Less is known, however, about the factors that sustain the level of athletes' attitudes towards doping. The main psychological (i.e., perfectionism, sport motivation, self-confidence and life satisfaction) and social correlates (i.e., social network and contact with people who use sports drugs) of attitudes towards doping among Italian athletes are examined in this paper. Differences are hypothesized regarding the type of sport (resistance sport vs. non-resistance sport) and athlete participation in competitive sport (i.e., agonistics) or in non-competitive sport (i.e., amateurs) on the level of attitude towards doping. The research hypothesis is that each of these constructs affects the level of athletes' attitudes toward doping. METHODS: Data were collected from a sample of athletes (N=109), aged from 15 to 45 (M=31.5; SD=13.78) recruited in a Sports Medicine Center. Socio-demographic information, attitude towards doping, psychological and social variables were assessed through self-report questionnaire. RESULTS: Hierarchical multiple regression showed that both psychological (i.e., extrinsic motivation, perfectionism) and social variables (i.e., athletes' contact with doping users) were associated with athletes' attitudes towards doping. CONCLUSIONS: The results highlighted that athletes with excessive perfectionism, extrinsically motivated and who have contact with doping users have a positive attitude toward doping. Athletes who exhibit these characteristics should be considered at risk and monitored to prevent possible future sports drug use.

Alcohol use and associated factors among adolescent students in Thailand / El uso de alcohol y factores asociados entre los estudiantes adolescentes de Tailandia

OBJECTIVE: Alcohol misuse is a relevant public health issue in Thailand. The assessment of the prevalence of alcohol use among adolescents may guide policies and programmes aimed at reducing alcohol use among this age group. METHOD: Using data from the Thailand Global School-based Student Health Survey (GSHS) 2008, we assessed the prevalence of alcohol use and the associated factors among adolescents (n = 2758). RESULTS: Overall, the prevalence of current alcohol use was 14.8% (21.2% males and 9.3% females). Variables positively associated with the outcome in multivariable analysis among boys were older age, other substance use (smoking and illicit drug use), sex in the past 12 months, physical fighting, injury in the past 12 months; and among girls, poverty, smoking, physical fighting and lack of parental or guardian connectedness. CONCLUSION: Efforts to prevent and control alcohol misuse may need to address a cluster of risk behaviours including cigarette smoking.

OBJETIVO: El abuso del alcohol es un problema de salud pública importante en Tailandia. La valoración de la prevalencia del uso de alcohol entre los adolescentes puede guiar las políticas y programas encaminados a reducir el uso del alcohol entre este grupo etario. MÉTODO: Usando datos de la Encuesta Mundial de Salud Escolar (GSHS) 2008, efectuada en Tailandia, se evaluó la prevalencia del uso del alcohol y los factores asociados, entre los adolescentes (n = 2758). RESULTADOS: En general, la prevalencia del uso del alcohol corrientemente fue 14.8% (21.2% varones y 9.3% hembras). Las variables positivamente asociadas con el resultado del análisis multivariable entre los muchachos fueron: tener más edad, uso de otra sustancia (hábito de fumar y uso ilícito de droga), sexo en los últimos 12 meses, pelea física, lesión en los últimos 12 meses. Entre las muchachas estas variables fueron: la pobreza, el hábito de fumar, la pelea física, y la falta de relación con los padres o los tutores. CONCLUSIÓN: Los esfuerzos por prevenir y controlar el abuso del alcohol entre los adolescentes pueden llevar a la necesidad de abordar una serie de comportamientos de riesgo, incluyendo el hábito de fumar.

Injury and social correlates among in-school adolescents in four Southeast Asian countries.

The aim of this study was to determine estimates of the prevalence and social correlates of injury among adolescents in four Southeast Asian countries. Cross-sectional national data from the Global School-based Health Survey (GSHS) included 9,333 students at the ages from 13 to 15 years inclusive from Indonesia, Myanmar, Sri Lanka and Thailand is chosen by a two-stage cluster sample design to represent all students in grades 6, 7, 8, 9, and 10 in each country. The percentage of adolescents reporting one or more serious injuries within the past 12 months was 42.2% for all countries, ranging from 27.0% in Myanmar to 46.8% in Thailand. By major activity, "fall" (14.6%) was the leading external cause of injury, followed by playing or training for a sport (9.9%) and vehicle accident (6.1%). In multivariate regression analysis Thailand and Indonesia, being male, substance use (smoking and drinking alcohol) and psychological distress were associated with annual injury prevalence. Risk factors of substance use and psychological distress should be considered in an integrated approach to injury etiology in planning injury prevention and safety promotion activities among school children.

Paternity determination, genetic characterization, and social correlates in a captive group of chimpanzees (Pan troglodytes).

In this study we use genetic fingerprints based on highly polymorphic microsatellite loci for paternity identification, apply some descriptive genetic measures and test social correlates of reproductive success in a group of captive chimpanzees. Using 6 microsatellites applied to 34 blood or muscle samples, we inferred sires for 16 offspring. Mean allele-sharing values revealed an increase in genetic relatedness from founder animals to animals born in the colony. Multi-dimensional scaling of genetic relatedness revealed only one patrilinear and no matrilinear clusters. Furthermore, individuals did not appear to produce offspring more often with partners that they mated with more often, that were higher-ranking, older or (in the case of females) of higher parity. There was also no association between male rank and shortterm reproductive success.
