Conclusions： The PE become knowledgeable to respond to the adolescent problems and readiness to become PE during puberty.

Image sequence-based risk behavior detection of power operation inspection personnel

A novel image sequence-based risk behavior detection method to achieve high-precision risk behavior detection for power maintenance personnel is proposed in this paper.In this method,the original image sequence data is first separated from the foreground and background.Then,the free anchor frame detection method is used in the foreground image to detect the personnel and correct their direction.Finally,human posture nodes are extracted from each frame of the image sequence,which are then used to identify the abnormal behavior of the human.Simulation experiment results demonstrate that the proposed algorithm has significant advantages in terms of the accuracy of human posture node detection and risk behavior identification.

Relationship between Sexual Risk Behaviors and HIV Counseling and Testing (HCT) Uptake among Young People in Nigeria

This study examined the relationship between sexual risk behavior and HIV counselling and testing uptake among young people in Nigeria. Probability sampling technique was used to obtain a sample of 10,091 respondents (ages 15 to 24 years) for the study. The multistage cluster sampling was used to select suitable young people with known probability. Data were collected throughout Nigeria between September and December 2012 from 32,543 households (rural = 22,192;urban = 10,351) using structured and semi-structured questionnaires. The data were summed using descriptive statistics. Frequencies and percentages;measures of central tendencies were used to answer the research question while nonparametric test such as chi-square was used to analyze non-normally distributed data at 0.5 level of significance. Results of data analysis indicated that sexual risk behaviors comprised three variables: sex with multiple partners, intergenerational sex (sex with partners 10 years older), and transactional sex. The results of the chi-square test of association between sex with multiple partners and HCT uptake showed that there was no statistically significant relationship between sex with multiple partners and HCT uptake among young people ages 15 to 24 years in Nigeria. It was among others recommended that sexually active young people in Nigeria should use protection against HIV infection.

AIDS-Related High-Risk Behaviors and Affecting Factors of Men Who Have Sex with Men (MSM) in China's Mainland

Objectives: To describe and analyze HIV/AIDS/STD-related high risk behaviors and affecting factors of men who have sex with men (MSM) in China's Mainland~ Methods: 426 self-administered or interview-based questionnaires collected from MSM were analyzed with SPSS or SAS Systems. Results: Of the MSM, four-fifths had engaged in oral-genital intercourse, about half had engaged in anal intercourse, and in the past year more than two-fifths had casual sexual partner(s).Very few maintained monogamous sexual relationships, and nearly half also had intercourse with women. One fourth had previously been diagnosed with a venereal diseases. One HIV+individual was found among the 40 who reported having been tested for HIV. Only two men consistently used condoms among the one-third who had ever used condoms, despite almost universal knowledge of HIV and its transmission. Conclusions: MSM in China's Mainland are very sexually active, highlighting the possibility of a serious HIV epidemic that may be directly spread to the female population. However,AIDS interventions targeting MSM face severe obstructions resulting from cultural bias and other factors.

The Relationship between AIDS High Risk Behaviors and Childhood Status, Perception of Gender Orientation and Rare Experiences/Psychology among Chinese Gays

Objectives : To probe some more important factors affecting the HIV epidemic by surveying the relationship between AIDS high risk behaviors and childhood status,attitude/perception to gender of male/sex orientation andrare experiences/Psy-chology among Chinese gays. Methods: Data were collected from 240 Chinese gays whowere attracted by their same gender. Results: The extent of sex among China's Mainland gays issimilar to that of industrialized countries, and behaviors that exacerbate the HIV epidemic are universal.Perceptions “being a girl is better”, “ Dislike toys likeswords or pistols in early childhood were predictors topassive anal intercourse in adulthood. Those gay men whobegan sexual intercourse younger than 16 years old tendedto have more sex partners and suffered more pain. Thosedisliked gender of male or self-regarded as female tended tohave more passive anal intercourse and related to childhood cross-gender experience/psychology while those were raised as girls by their parentsdid not take on the above characters. Individuals who experienced sex coercion and drug abuse were the twosubgroups with the greatest high-risk behaviors. Individualswho had sex with females had the greatest number of malesex partners and were more prone to group sex. Individualswith pedophilia or gerontophilia had more casual sexpartners. Psychological problems encountered by Chinesegays related to suicide attempts and commitment. Conclusions : The prospect of an extensive AIDSepidemic among Chinese gays does exist and somesubgroups of gays play more important roles in theepidemic. Some high risk behaviors among adult gays canbe foreseen explicitly by the predictors taking on inchildhood, and closely relate to attitude/perception, togender of male, to some rare experience/psychology.

Life Style and Risk Behavior of Street Children in Bangladesh: A Health Perspective

Background: Street children concern to millions of deprived boys and girls who have adopted the street as their residence. They grow up where tranquility and physical and emotional stability are frequently threatened. The purpose is to have an empathetic look into the lives of street children for identifying their health-related needs. Method: A cross sectional descriptive type of study was conducted among 125 street children between the ages 8 to 14 years who were available at different intercept points of Dhaka city, Bangladesh. The information was collected through face-to-face interview using a structured questionnaire. An attempt was made to relate their lifestyle, risk behavior and health impact upon the socio demographic characteristics. Result: According to the statement of street children, poverty (41%) is the main reason behind enforcing the children to stay and work on the street. They pass their leisure by playing games, roaming around by watching video/cinema but on the other side of the coin, they are frequently abused (80.8%) either physically or sexually. Regarding health, about 87.2% of street children were suffering from different type of diseases as accidental injury, skin infection, hepatitis, sexually transmitted diseases and warm infestation. Conclusion: A careful examination of the lives of these children will provide a clearer understanding of their disadvantageous life. A better diagnosis of the contributing factors will help to minimize the extent of the problems and also to develop innovative approaches and ensure a healthy lifestyle, protection and rehabilitation for those children.

STUDY ON HIV/STDS KNOWLEDGE AND RISK BEHAVIORS RELATED FACTORS AMONG FEMALE SEX WORKERS IN SHANGHAI,CHINA

Objective To assess the HIV/STDs knowledge and risk behaviors related factors among female sex workers(FSWs)in Shanghai,China.Methods A cross-sectional study was conducted in 5 districts(including 3 suburbs and 2 urban districts).A total of 324 FSWs from 88 massage parlors and hair-beauty salons participated in the survey.An interviewer-administrated questionnaire was used to collect information.Results The average score of HIV/STDs knowledge was 15.2±3.9.Multivariate analyses indicated that limited education [odds ratio(OR):8.6,95% confidence interval(CI):2.9-25.6],coming from suburbs [odds ratio(OR):3.7,95% confidence interval(CI):2.0-6.8],monthly income less than 1500 RMB(220 US$)[odds ratio(OR):3.9,95% confidence interval(CI):1.9-8.1],without HIV/STDs-related education experience(OR:5.2,95% CI:2.8-9.5),and coming from provinces of low epidemic(OR:2.7,95% CI:1.1-6.6)were significant predictors of lower HIV/STDs knowledge.And 29.5% FSWs had sex without a condom when clients paid much more money,and 46.3% had the experience of condom broke or slipped during commercial sexual intercourse.Conclusion Health promotion should be conducted to enhance HIV/STDs knowledge and reduce risk behaviors among FSWs from suburbs with limited education in Shanghai especially.

Parenting Skills Determinant in Preventing Adolescents’ Sexual Health Risk Behavior

Parenting skill is one of the crucial needs that parents must have in caring adolescents’ sexual health risk behavior. Present study aims to determine predictors of parenting skills in preventing adolescents’ sexual health risk behavior. A cross sectional study was conducted among adolescents’ parents who attended government health clinics in a semi-urban district, West Malaysia. Data were collected by systematic random sampling using validated questionnaire from eight government health clinics based on routine daily out-patient services. There were 386 respondents participated with 98.9% of response rate. Parental skill is categorized as appropriate or inappropriate based on Trans-Theoretical Model (TTM) staging. Eighteen independent variables were used: parental socioeconomic status, adolescent characteristic, parenting style, parent-adolescent communication, parental stress, perception on adolescent sexual risk, comfortable in discussing sexual issues, knowledge in sexual reproductive health (SRH) and knowledge in HIV/AIDS. Assessment of parenting skills using the TTM stage showed 139 respondents (36%) had inappropriate parenting skills, in which they were in pre contemplation, contemplation or preparedness stages, while 247 respondents (64%) showed appropriate parenting skills when they were in action and maintenance stages of TTM. Older parent, late adolescent, low parental education level, extended family living arrangement, comfortable in discussing sexual issues, good parent-adolescent communication and higher knowledge in HIV/AIDS were found significant in bivariate analysis. Multivariate logistic regression analysis identified older parent (AOR = 1.927, 95% CI = 1.889 - 1.966, p < 0.001), lower parental education (AOR = 2.394, 95% CI = 1.348 - 4.254, p = 0.003), comfortable in discussing sexual issues (AOR = 3.810, 95% CI = 1.622 - 8.948, p = 0.002), good parent-adolescent communication (AOR = 4.741, 95% CI = 2.478 - 9.071, p ≤ 0.001) and having higher knowledge on HIV/AIDS (AOR = 2.804, 95% CI = 1.528 - 5.147, p = 0.001) as significant predictors for appropriate parenting skills in preventing adolescent sexual health risk behavior. In conclusion, more than one third of parents were still not ready in preventing adolescent sexual risk behavior. Targeting the young parents and those having difficulty in communicating sexual issues with theirs adolescents should be emphasized in early intervention program for parents. Self-assessment using TTM stage questionnaire will help parents to identify their parenting skills in preventing adolescent sexual health risk behavior.

Relationships of youth risk behaviors with norm-consciousness and resilience among Japanese high school students

The purpose of this study was to examine the influences of norm-consciousness and resilience on the prevention of youth risk behaviors among Japanese high school students. Data of a national survey, Japan Youth Risk Behavior Survey 2011, was used for this analysis. The subjects were 9778 students (5027 males, 4751 females) in grades 10-12 in 102 schools randomly selected from among high schools throughout Japan. When multiple regression analysis was carried out using four subdomains of norm-consciousness and three subdomains of resilience as the independent variables and nine risk behaviors as the dependent variables, the subdomains of norm-consciousness showed significant positive standardized partial regression coefficients for eight risk behaviors for both males and females. In particular, “current alcohol use” and “ever had sexual intercourse” showed the largest standardized partial regression coefficients for the norm-consciousness in school, and “current cigarette use” showed that for the norm-consciousness in community. The subdomains of resilience showed significant positive standardized partial regression coefficients for five risk behaviors for males and for six those for females. The results of this study suggest that the norm-consciousness is an important protective factor to comprehensively prevent risk behaviors among Japanese adolescents. It is expected to be effective to enhance the norm-consciousness particularly in school and community. In addition, resilience should also be emphasized as a factor to prevent specific risk behaviors.

Clustering of Multiple Risk Behaviors among Ethnically Diverse Adolescents Living in Hawaii

The current study examined the prevalence and clustering of 5 health-risk behaviors among adolescents in Hawaii, including physical inactivity, low fruit and vegetable consumption, junk food consumption, excessive television time, and inadequate sleep. High school students were recruited from 5 classrooms in Oahu Hawaii. Data were collected in the spring semester of 2011. Proportions were used to describe the prevalence of single and multiple health risk behaviors. Significant health behavior clusters were revealed using an observed-to-expected (O/E) ratio method. Participating adolescents (n = 114) were 11th and 12th grade students with a mean age of 16.28 (SD = 0.62). Participants were predominantly female (75%) and Filipino-American (68%). Seventy-seven percent of adolescents were physically inactive, 90% watched excessive TV, 66% consumed inadequate fruits and vegetables, 94% reported inadequate levels of sleep, and 80% consumed excessive junk food. Overall, 94% reported at least 3 risk factors, 73% reported at least 4 risk factors, and 37% reported all 5 risk factors. No significant clusters were found. Conclusion: Health-risk behaviors cluster and occur more often than expected among adolescents living in Hawaii. Non-significant clustering may be due to insufficient variability within the sample data;future examinations of this highly understudied population are necessary.

Explanatory Models of Inmate HIV Risk Behaviors: Does a Fatalistic Model Exist?

The deprivation, importation, situational, and administrative control models have been used to explain inmate violence. More recently, HIV risk behaviors of inmates have been explained with the deprivation and importation models. The goal of this study is to assess the utility of these models in describing inmate HIV risk behaviors and to identify additional models that may exist. Forty seven ex-offenders released from prison within three months of the study were recruited from a community based organization. They participated in focus group discussions that explored the contexts surrounding inmate engagement in HIV risk behaviors in prison. Data were analyzed using NVivo 7 and results were organized into themes. Inmates engaged in sex in exchange for money and for affection. Inmates who were drug users before incarceration were more likely to abuse drugs in prison. Security measures, if effective, deterred the entrance of illegal substance into prison, but when security is lax, inmates take the opportunity to engage in sex, and illegal substances are brought into prison. Our results reveal that deprivation, importation, situational, and administrative control factors are associated with HIV risk behaviors among inmates and they can be used in explaining these behaviors. The association of risk behaviors with long or life sentences suggests that fatalism may play a role in risk behaviors among inmates. Fatalism is a factor which requires future examination.

Prevalence and Incidence of HIV and Sexual Risk Behaviors in Crack Users in the San Salvador Metropolitan Area, El Salvador

Objective: It is in order to estimate the prevalence and incidence of HIV, the frequency of sexual risk behaviors, and perceptions of available resources to prevent and treat HIV among crack users in the San Salvador Metropolitan Area. Methods: We conducted a survey of 420 crack users by using respondent-driven sampling to measure demographic characteristics, the quantity and frequency of drug use, history of STIs, including HIV, and experiences with organizations which provide prevention and treatment of HIV. Each participant offered a free and voluntary HIV test and was asked permission to share the results of the test with the study. Bernoullian modeling was used to estimate the prevalence and incidence of HIV among heterosexual males in this population. Results: The estimated prevalence was 7% (95% CI: 2.3% -9.8%) among participants who agreed to take the test and share the results, and 4.9% (95% CI: 2.8% -7.8%) assuming that those who did not take the test or share results were seronegative. Participants reported a high frequency of sexual risk behaviors. In addition, participants were reported to have little knowledge of organizations to prevent or treat HIV/AIDS;58% had never taken an HIV test prior to survey administration. Conclusions: Crack users in San Salvador are at high risk for HIV acquisition. HIV prevention interventions are urgently needed, especially interventions increasing access to HIV testing and prevention.

Prevalence of Human Immunodeficiency Virus (HIV), Risk Behavior, and Recent Substance Use in a Sample of Urban Drug Users: Findings by Race and Sex

The aim of the current study was to examine the prevalence of HIV, past six-month illicit drug use, and risk behaviors among a population of heavy drug users living in an urban setting. Although many studies investigate substance use, sex-risk behavior, and HIV by race and gender, no studies have examined these variables simultaneously. The current study seeks to fill this gap in the literature by exploring HIV prevalence among a predominantly heterosexual sample of recent substance users by injection drug use (IDU) status, race, and sex. Baseline data from the Baltimore site of the NEURO-HIV epidemiologic study was used in this study. This study examines neuropsychological and social-behavioral risk factors of HIV, hepatitis A, hepatitis B, and hepatitis C among both injection and non-injection drug users. Descriptive statistics and chi-square statistics were used in data analyses. Blood and urine samples were obtained to test for the presence of recent drug use, viral hepatitis, HIV, and other sexually transmitted diseases (STDs). Findings presented here have several important implications for HIV prevention and care among substance users. Intervention programs that incorporate substance use treatment in addition to HIV education, particularly with respect to substance use and sex risk behavior are imperative.

Evidence for the Reliability and Validity of the Arabic Version of the Student Risk Screening Scale for Internalizing and Externalizing Behaviors (SRSS-IE)

School-based universal screening for behavioral/emotional risk is a necessary first step to providing services in an educational setting for students with emotional and behavioral disorders (EBDs). Psychometric properties are critical to making decisions about choosing a screening instrument. The purpose of the present study was to examine the psychometric properties of the student risk screening scale for internalizing and externalizing behaviors (SRSS-IE). Participants included 3145 students and their teachers. Item-level analyses of the current sample supported the retention of all items. The internal consistency of the SRSS items ranged from 0.83 to 0.85. Convergent validity between the SRSS-IE and a well-established screening tool, the strength and difficulties questionnaire (SDQ), was found for the total score (r = 0.70). Additionally, the results of this study demonstrate strong social validity, suggesting the SRSS-IE to be a useful and functional screening tool. We conclude that the SRSS-IE is a valid and reliable instrument for assessing the level of emotional and behavioral difficulties among elementary students.

Assessing current faulting behaviors and seismic risk of the Anninghe-Zemuhe fault zone from seismicity parameters

Using the data of regional seismic network, this paper analyzes the current faulting behaviors of different segments of the Anninghe-Zemuhe fault zone, western Sichuan, and identifies the likely risky segments for potential large earthquakes. The authors map the probable asperities from the abnormally low b-value distribution, develop and employ a method for identifying current faulting behaviors of individual fault segment from the combinations of multiple seismicity parameter values, and make an effort to estimate the average recurrence intervals of character-istic earthquakes by using the parameters of magnitude-frequency relationship of the asperity segment. The result suggests that the studied fault zone contains 5 segments of different current faulting behaviors. Among them, the Mianning-Xichang segment of the Anninghe fault has been locked under high stress, its central part is probably an asperity with a relatively large scale. The Xichang-Puge segment of the Zemuhe fault displays very low seismicity under low stress. Both the locked segment and the low-seismicity segment can be outlined on the across-profile of relocated hypocenter depths. The Mianning-Xichang segment is identified to be the one with potential large earth-quake risk, for which the average recurrence interval between the latest M = 6.7 earthquake in 1952 and the next characteristic event is estimated to be 55 to 67 years, and the magnitude of the potential earthquake between 7.0 and 7.5. Also, it has been preliminarily suggested that for a certain fault segment, its faulting behaviors may change and evolve with time gradually.

Clustering of Risk Behaviors and their Social Determinants among Primary School Learners in Beijing, China：A Cross-sectional Study

Background：Studies in developed countries reveal that poor lifestyle choices triggering diseases typically cluster among children.However,there is insufficient evidence on the clustering of risk behaviors among children in developing countries.This study aimed to determine the clustering of risk behaviors and their social determinants among 4th-and 5th-grade learners in Beijing,China.Methods：The sample comprised of 967 learners from six primary schools enrolled migrant and resident learners by two-stage stratified cluster sampling.Prevalence denoted the risk behaviors and their clustering.A log-linear model was used to explore the clustering patterns.Ordinal logistic regression determined the influence of demographic characteristics,school environment,and family context on behavioral clustering.Results：The prevalence of none,one,two,and three or more risk factors was 61.2%,20.0%,10.8%,and 8.1% for infectious diseases and 46.0%,30.6%,15.4%,and 8.0% for chronic diseases,respectively.Some behaviors appeared dependent and were more likely to be observed together.The three most influential factors for infectious diseases were school type （odds ratio [OR] =4.47,95% confidence interval [CI] 3.00-6.66）,school located in an inner suburb （OR =0.27,95% CI 0.18-0.38）,and gender （OR =0.56,95% CI 0.42-0.74）.Regarding risk behaviors for chronic diseases,clustering was not associated with household registration status and number of appliances,but was significantly associated with school type （OR =5.36,95% CI 3.72-7.73）,school located in an inner suburb （OR =0.59,95% CI 0.43-0.81）,and gender （OR =0.61,95% CI 0.47-0.78）.School environment variables were the most significant contributor to the number of risk behaviors.Conclusions：The characteristics of schools enrolling migrants and residents influenced the number of risk behaviors.Therefore,improved school conditions and integrated behavioral interventions are particularly recommended for health promotion.

Association between Selenium in Soil and Diabetes in Chinese Residents Aged 35–74 Years:Results from the 2010 National Survey of Chronic Diseases and Behavioral Risk Factors Surveillance

Objective To explore the association between soil selenium levels and the risk of diabetes in Chinese adults aged 35–74 years.Methods Data for this study were derived from the China Chronic Diseases and Behavioral Risk Factors Surveillance 2010 survey.Selenium concentrations in soil were obtained from the Atlas of Soil Environmental Background Values in China.A two-level binary logistic regression model was used to determine the association between soil selenium concentrations and the risk of diabetes,with participants nested within districts/counties.Results A total of 69,332 participants aged 35–74 years,from 158 districts/counties were included in the analysis.Concentrations of selenium in soil varied greatly across the 158 districts/counties,with a median concentration of 0.219 mg/kg(IQR:0.185–0.248).The results showed that both Quartile 1(0.119–0.185 mg/kg)and Quartile 4(0.249–0.344 mg/kg)groups were positively associated with diabetes compared to a soil selenium concentration of 0.186–0.219 mg/kg(Quartile 2),crude odds ratios(ORs)(95%CI)were 1.227(1.003–1.502)and 1.280(1.048–1.563).The P values were 0.045 and 0.013,for Quartile 1 and Quartile 4 groups,respectively.After adjusting for all confounding factors of interest,the Quartile 1 group became non-significant,and the Quartile 4 group had an adjusted OR(95%CI)of 1.203(1.018–1.421)relative to the reference group(Quartile 2),the P values was 0.030.No significant results were seen for the Quartile 3 group(0.220–0.248 mg/kg)compared to the reference group.Conclusion Excessive selenium concentrations in soil could increase the risk of diabetes among Chinese adults aged 35–74 years.

Preventing Behavioral-Risks Incidence among School Children: The Role of School-Based Health Promotion Program

This article addresses the important role school health education program can play in reducing youth risky behaviors that lead to incarceration, diseases and fatalities or that impact their academic performance in school. Children growing up are at risks of exposure to different behaviors and common social influences which if unchecked result in unexpected health consequences common among youth in America today. According to US Centers for Disease Control & Prevention, the six leading behaviors that cause death, disability, and social problems among American children are: unintentional injuries and violence, alcohol and drug use, tobacco use, unhealthy diets, inadequate physical activities, and sexual behaviors and diseases. This article shows that school health program: 1) can provide the foundation for children to learn desired healthy behaviors in order to preserve life, 2) protects the future of children and that of the nation, 3) can teach students skills to recognize risky behaviors and resist them, 4) can boost community efforts to achieve desired health behaviors, 5) closes socio-economic gaps that interfere with basic nurturing of children, and 6) finally links local stakeholders as partners in promoting community safety. Through review of literature, the authors found that it costs ($588) daily or (214,620) annually to incarcerate a juvenile and only $75 daily for the cost of individualized community-based services. The cost to New York is over $900,000, yet does not address the causative issues. The authors recommend that schools teach comprehensive school health from kindergarten to grade 12 and employ health educators to support teachers teach health promotion and education.

Study on Antibiotic Prophylactic Use Behavior and Influencing Factors of Livestock and Poultry Breeding Farms and Households from Risk Cognitive Perspective

Based on the theory of planned behavior( TPB),Taking 399 livestock and poultry farms and households in Shandong Province as samples,risk cognitive variables were introduced. Besides,with the aid of the structural equation model( SEM) and partial least squares method( PLS),through an empirical analysis on antibiotic prophylactic behavior of livestock and poultry breeding farms and households in the context of " antibiotic free" production,the response mechanism of " antibiotic free" production was explored. Results indicated that the use of antibiotic prophylaxis by livestock and poultry farms and households is still very common. In the observation samples,61. 4% clearly expressed they would use antibiotic prophylaxis; the understanding of hazard of improper antibiotic prophylaxis was inadequate,only 32. 3% breeding households believed that the overuse of antibiotic prophylaxis is the main reason leading to excessive drug residue in animal products. This study was in line with the process of deduction of TPB. The breeding households' reduction of antibiotic prophylaxis is influenced by their intentions,while the intention is influenced by the attitude,subjective norms and perceptual behavior control; different risks have different influences,but most risks have greater influence on perceptual behavior control,because the perceptual behavior control determines whether breeding households have the ability of implementing the corresponding behavior.
