    BACKGROUND: In welfare institutions, it is essential to address the health-related needs of adolescent populations who often engage in sexual activities. This study examines the association between individual and interpersonal factors concerning sexual risk behaviour (SRB) among adolescents in welfare institutions in Malaysia.

    METHODS: Data were derived from a cross-sectional study of 1082 adolescents in 22 welfare institutions located across Peninsular Malaysia in 2009. Using supervised self-administered questionnaires, adolescents were asked to assess their self-esteem and to complete questions on pubertal onset, substance use, family structure, family connectedness, parental monitoring, and peer pressure. SRB was measured through scoring of five items: sexual initiation, age of sexual debut, number of sexual partners, condom use, and sex with high-risk partners. Multivariate logistic regression analysis was used to examine the various predictors of sexual risk behaviour.

    RESULTS: The study showed that 55.1% (95%CI = 52.0-58.2) of the total sample was observed to practice sexual risk behaviours. Smoking was the strongest predictor of SRB among male adolescents (OR = 10.3, 95%CI = 1.25-83.9). Among females, high family connectedness (OR = 3.13, 95%CI = 1.64-5.95) seemed to predict the behaviour.

    CONCLUSION: There were clear gender differences in predicting SRB. Thus, a gender-specific sexual and reproductive health intervention for institutionalised adolescents is recommended.

    Entomological surveillance was conducted in order to determine the abundance and to evaluate any changes of biological vectors or ecology, especially in the dengue outbreak areas. The abundance and breeding preference of Aedes albopictus and Aedes aegypti were conducted in selected dengue outbreak localities in three states of peninsular Malaysia namely Selangor, Federal Territory of Kuala Lumpur, and Penang Island using ovitraps and larval survey method. It was determined that Ae. albopictus was predominant in most of the localities and found to breed more outdoor than indoor. A wide range of breeding foci were recorded in this study. It was also determined that ovitrap method was more effective to detect the presence of Aedes mosquitoes when the larval survey was at low rate of infestation. The abundance of Ae. albopictus in dengue outbreak localities emphasis that the vector control programme should also target this species together with the primary dengue vector, Ae. aegypti.

    Pregnancy among unmarried women may have negative social and health implications in Malaysia. The number of pregnancies among unmarried women has increased in Malaysia, but the socio-demographic profile of these women is unclear. This study aims to evaluate the characteristics of unmarried pregnant women and the factors associated with unmarried pregnancies among young women in Malaysia. We conducted a cross sectional study at six hospitals and six women's shelters in Peninsular Malaysia during 2011-2012. Unmarried pregnant women were compared with married pregnant women. Participants were interviewed using a structured questionnaire asking for socio-demographic data, family background, risky sexual behavior, social support and pregnancy details. A total of 484 women (239 unmarried and 245 married) were included in the study. Most unmarried subjects were adolescents, from urban areas, from a low socioeconomic group, and lived with parents prior to pregnancy. Age (OR=0.67; 95% CI: 0.61-0.74), studying status (OR=17.33; 95% CI: 2.65-113.19), alcohol use (OR=40.46; 95% CI: 2.51-652.38) exposure to pornographic material (OR=13.48; 95% CI: 3.24-56.01), contraceptive use (OR=0.20; 95% CI: 0.08-0.51), and social support (OR=0.90; 95% CI: 0.86-0.94) were all associated with unmarried pregnancy. These factors need to be considered when.designing an intervention program.

    A module entitled 'SayangKU' (MyLove), based on the Islamic perspective, was developed as an instrument to assist adolescents that involved in premarital sexual activity. The module comprises four phases: Love of God (Allah), Love of the Prophet, Love of Oneself, and Love of the Ummah (world). From analysis of Rasch, the value of item reliability was .80 and an individual reliability was .95. Dimensionality value was more than 40 % variance explained by measures, and level of agreement among experts was 86.88 %. The posttest shows the better result from pretest and proves the effectiveness of the module.

    According to neurohormonal theory, prenatal androgens are key determinants of sexual orientation. As a reputed marker for prenatal androgens, the 2D:4D finger length ratio has been used in more than a dozen studies to test the hypothesis that prenatal androgens influence sexual orientation. Findings have been very inconsistent.

    Systemic sclerosis is a chronic multi-organ autoimmune disease, leading to important clinical and psychological implications. Among organ complications, sexual dysfunction is a major issue for both male and female gender, with high prevalence and great impact on quality of life, although frequently not addressed by both clinicians and patients. While erectile dysfunction is the most common cause of sexual problems in males, genital tract and general physical changes are major contributors to sexual impairment in females. This review presents current state of the art on this topic, discussing published data on presentation, evaluation and therapeutic options.

    Mating behavior between Aedes aegypti and Ae. albopictus, established colony strains were examined under laboratory conditions (30-cm(3) screened cages) for 5 consecutive days. The effect of selected male densities (30, 20, 10) and female density (20) on the number of swarming, mating pairs, eggs produced, and inseminated females were evaluated. Male densities significantly increased swarming behavior, mating pairs, and egg production of heterospecific females, but female insemination was reduced. Aedes aegypti males mate more readily with heterospecific females than do Ae. albopictus males. The current study suggests that Ae. aegypti males were not species-specific in mating, and if released into the field as practiced in genetically modified mosquito techniques, they may mate with both Ae. aegypti and Ae. albopictus females, hence reducing populations of both species by producing infertile eggs.

    BACKGROUND:
    The main sexual and reproductive health issues among young people are premarital sexual intercourse, unwanted pregnancies, unsafe abortions and sexually transmitted diseases including Human Immunodeficiency Virus. The aim of this study was to determine the knowledge related to sexual and reproductive health among Malaysian postgraduate students in a public university in Malaysia.

    METHODS:
    A cross-sectional study was carried out among postgraduate students by systematic random sampling technique. A pre-tested self administered questionnaire was used to collect the data.

    RESULTS:
    Out of 434 respondents, the majority of students were female (78.6 %) and single (78.3 %). The overall mean age of respondents was 27.0 ranging from 20 to 46 years of age. The main sources of information for sexual and reproductive health awareness were the internet (78.6 %) and newspaper (61.8 %). The majority (97.9 %) of the students knew that AIDS is a sexually transmitted disease. Most of them believed that the spread of sexually transmitted diseases was through shaking hands (92.1 %). Use of condoms was perceived to be the best way to avoid sexually transmitted diseases (88.4 %). Sexual and reproductive health knowledge was significantly associated with the students' age, marital status and faculty. The socio-demographic factors and current educational status accounted for a significant 9 % of the variability in sexual and reproductive health knowledge, f (7, 426) = 11, p <0.001.

    CONCLUSIONS:
    The postgraduate students' level of knowledge on sexual and reproductive health was not satisfactory. Sexual and reproductive health knowledge was associated with the students' marital status and faculty. Intervention programs related to sexual and reproductive health are recommended.

    Smoking among rural adolescents in Malaysia is on the rise with a significant difference seen between urban and rural youths. Therefore, this study was carried out to determine a predictive model of smoking among the rural-school adolescents population in Malacca, Malaysia. An unmatched case-control study was conducted in 2010 involving 484 cases and 444 controls of Form Two students in Malacca, Malaysia, using cluster sampling. Smoking was the dependent factor of this study while the independent factors were individual, family, school and environment. Data were obtained through a self-administered questionnaire. The response rate of the study was 100% whereas the smoking prevalence was 20.9%. Binary logistic regression was used to determine the smoking predictive model. Strong predictors of smoking behaviour were: influenced by artistes who smoke (Adjusted OR=8.67, 95% CI 5.53-13.58); the male gender (Adjusted OR=6.7, 95% CI 4.14-10.83); Muslim (Adjusted OR=4.46, 95% CI 2.36-8.44); and the belief that smoking is not dangerous when the teacher is seen smoking as well (Adjusted OR=3.95, 95% CI 2.19-7.10). Other predictors were: being offered cigarettes by friends (Adjusted OR=2.81, 95% CI 1.79-4.42); the belief that smoking will relax the mind (Adjusted OR=2.45, 95% CI 1.33-4.51); having friends who smoke (Adjusted OR=2.32, 95% CI 1.29-4.81); forced by friends to smoke (Adjusted OR=2.17, 95% CI 1.15-4.12); have heard of the national No-Smoking Campaign (Adjusted OR=1.89, 95% CI 1.06-3.37); have problems with the school management (Adjusted OR=1.75, 95% CI 1.07-2.88); parental consent to watch sexual activities, drug use or violence on television or at the cinema (Adjusted OR=1.73, 95% CI 1.06-2.83); and have lunch in school (Adjusted OR=1.58, 95% CI 1.04-2.41). This paper ends with the recognition of the need for intervention in dismantling the predictors that can lead to the development of smoking among Malaysian adolescents in rural schools. of different pathological entities.

    The recent expanding rat population is causing severe economic losses and diseases in human. The main objective of this study was to evaluate the antifertility effects of Andrographis paniculata (AP) methanol extract on the weight of testis, sexual behaviour, fertility, sperm quality and serum testosterone level in treated male rats compared with control rats. A total of 21 adult male rats Sprague-Dawley aged 12 weeks were divided into three groups; control group (distilled water), low dose group (800 mg/kg) and high dose group (1600 mg/kg) of AP methanol extracts given orally for 24 days. Body and testis weight, sexual behaviour test, fertility test, sperm quality and serum testosterone level were measured. Oral administration of AP methanol extract showed a significant decrease in testis weight, number of mountings, number of fetuses, sperm count, sperm motility and serum testosterone levels for all treatment group as compared with the control group, whereas mortality showed a significant increase. Observation on testis histology of treatment group exhibited features of degeneration in Sertoli cells and germinal cells in the seminiferous tubules, followed by the shrinkage of Leydig cells as compared with the control group, which showed characteristics of normal spermatogenesis. In conclusion, AP methanol extract exhibited antifertility effects in male rats, suggesting that AP is a potential herb to be applied as rodenticide.

    Fishermen in Southeast Asia have been found to be highly vulnerable to HIV, with research evidence highlighting the role of sexual risk behaviors. This study aims to estimate the rate of HIV as well as hepatitis C virus (HCV) infections among Malaysian fishermen, and the risky sexual and injection drug use behaviors that may contribute to these infections. The study also includes an assessment of socio-demographic, occupational and behavioral correlates of testing positive for HIV or HCV, and socio-demographic and occupational correlates of risk behaviors. The study had a cross-sectional design and recruited 406 fishermen through respondent-driven sampling (RDS). Participants self-completed a questionnaire and provided biological specimens for HIV and HCV testing. We conducted and compared results of analyses of both unweighted data and data weighted with the Respondent-Driven Sampling Analysis Tool (RDSAT). Of the participating fishermen, 12.4% were HIV positive and 48.6% had HCV infection. Contrary to expectations and findings from previous research, most fishermen (77.1%) were not sexually active. More than a third had a history of injection drug use, which often occurred during fishing trips on commercial vessels and during longer stays at sea. Of the fishermen who injected drugs, 42.5% reported unsafe injection practices in the past month. Reporting a history of injection drug use increased the odds of testing HIV positive by more than 6 times (AOR = 6.22, 95% CIs [2.74, 14.13]). Most fishermen who injected drugs tested positive for HCV. HCV infection was significantly associated with injection drug use, being older than 25 years, working on a commercial vessel and spending four or more days at sea per fishing trip. There is an urgent need to strengthen current harm reduction and drug treatment programs for Malaysian fishermen who inject drugs, especially among fishermen who work on commercial vessels and engage in deep-sea fishing.

    Findings on the demographic and sexual health characteristics associated with the experience of a crisis pregnancy are important to inform the public health policy of a country, including Ireland. Studies from other jurisdictions have suggested that certain demographic groups are at risk for unintended pregnancies and the disparity between the groups has been growing in recent years. Ireland is a country which experienced much economic and societal change in the first decade of the 21(st) century; changes which are likely to have affected demographic variables pertaining to sexual health. The current study had two aims: to investigate changes in the socioeconomic characteristics associated with crisis pregnancies over a seven year period [2003 to 2010], and to investigate the recent [2010] socioeconomic risk factors associated with crisis pregnancies in Ireland.

    BACKGROUND: Sexual history training during undergraduate education is essential for preparing future doctors to handle patients' sexual health concerns. The purpose of this study was to assess the attitudes and perceptions of final-year medical students in Malaysia toward sexual history taking and the training they receive from their medical schools.
    METHODS: The study used a cross-sectional survey of 379 final-year medical students from three medical schools in Malaysia. Students were asked to rate their attitudes and perceptions regarding training on taking sexual histories using a newly developed questionnaire with good internal consistency (Cronbach's alpha = 0.73). Ethics approval was obtained from the relevant medical schools, and the statistical analysis was conducted using SPSS, Version 20.0.
    RESULTS: The mean age of participants was 23.58 ± 0.65 SD. Participants reported high interest in sexual health and felt it was important for doctors to know how to take a sexual history (95%). Among the participants, only half felt comfortable in taking sexual histories from patients. The participants identified cultural and religious differences between the doctor and the patient as a potential barrier for discussing sexual health. Participants were aware of their own practice and ability, as well as their limitations, in taking sexual histories. Less than half (46%) felt that the training they received adequately prepared them to take sexual histories.
    CONCLUSIONS: This study identified gaps in sexual health training among medical schools in Malaysia. The delivery of sexual health education program should incorporate confidence building and to make students feel comfortable to take sexual histories from patients. The barrier caused by differences in culture or religion between a doctor and a patient may be overcome through cross cultural and cultural competency training. This is important for multi-faith, multi cultural societies such as Malaysia and other similar countries.

    BACKGROUND: More effective mosquito control strategies are urgently required due to the increasing prevalence of insecticide resistance. The sterile insect technique (SIT) and the release of insects carrying a dominant lethal allele (RIDL) are two proposed methods for environmentally-friendly, species-targeted population control. These methods may be more suitable for developing countries if producers reduce the cost of rearing insects. The cost of control programs could be reduced by producing all-male mosquito populations to circumvent the isolation of females before release without reducing male mating competitiveness caused by transgenes.

    RESULTS: An RNAi construct targeting the RNA recognition motif of the Aedes aegypti transformer-2 (tra-2) gene does not trigger female-to-male sex conversion as commonly observed among dipterous insects. Instead, homozygous insects show greater mortality among m-chromosome-bearing sperm and mm zygotes, yielding up to 100% males in the subsequent generations. The performance of transgenic males was not significantly different to wild-type males in narrow-cage competitive mating experiments.

    CONCLUSION: Our data provide preliminary evidence that the knockdown of Ae. aegypti tra-2 gene expression causes segregation distortion acting at the level of gametic function, which is reinforced by sex-specific zygotic lethality. This finding could promote the development of new synthetic sex distorter systems for the production of genetic sexing mosquito strains.

    Many HIV-infected individuals do not enter health care until late in the infection course. Despite encouraging earlier testing, this situation has continued for several years. We investigated the prevalence of late presenters and factors associated with late presentation among HIV-infected patients in an Asian regional cohort. This cohort study included HIV-infected patients with their first positive HIV test during 2003-2012 and CD4 count and clinical status data within 3 months of that test. Factors associated with late presentation into care (CD4 count <200 cells/μl or an AIDS-defining event within ±3 months of first positive HIV test) were analyzed in a random effects logistic regression model. Among 3,744 patients, 2,681 (72%) were late presenters. In the multivariable model, older patients were more likely to be late presenters than younger (≤30 years) patients [31-40, 41-50, and ≥51 years: odds ratio (OR) = 1.57, 95% confidence interval (CI) 1.31-1.88; OR = 2.01, 95% CI 1.58-2.56; and OR = 1.69, 95% CI 1.23-2.31, respectively; all p ≤ 0.001]. Injecting drug users (IDU) were more likely (OR = 2.15, 95% CI 1.42-3.27, p < 0.001) and those with homosexual HIV exposure were less likely (OR = 0.45, 95% CI 0.35-0.58, p < 0.001) to be late presenters compared to those with heterosexual HIV exposure. Females were less likely to be late presenters (OR = 0.44, 95% CI 0.36-0.53, p < 0.001). The year of first positive HIV test was not associated with late presentation. Efforts to reduce the patients who first seek HIV care at the late stage are needed. The identified risk factors associated with late presentation should be utilized in formulating targeted public health intervention to improve earlier entry into HIV care.
