    One of the popular approaches of preventing youth sexual activity in Malaysia is using religion to promote premarital sexual abstinence. Despite this intervention, youth continue to practise premarital sex. Thus, the purpose of this exploratory mixed methods study was to understand the role of religion on sexual activity among college students in Klang Valley, Malaysia. A self-administered questionnaire survey to determine the relationship between religiosity and youth sexual activity was carried out on 1026 students recruited from 12 randomly selected colleges. Concurrently, face-to-face interviews were conducted on 15 students to explore how religiosity had influenced their decision on sexual activity. The survey data were analysed using logistic regression, while the qualitative data from the interviews were examined using thematic analysis with separate analysis for each gender. Both quantitative and qualitative results were then compared and integrated. Religious activity significantly reduced the risk of continuing sexual activity among female students (AOR = 0.67, CI = 0.47, 0.95, p = 0.02) but not male students. There was no significant relationship of religious affiliation and intrinsic religiosity (inner faith) to sexual activity by gender. Having faith in religion and strong sexual desire were the main themes that explained participants' sexual behaviour. Engaging in religious activity might be effective at preventing female students from being sexually active. However, when sexual urges and desires are beyond control, religiosity might not be effective.

    This cross-sectional study aimed to determine the prevalence and the factors associated with sexual initiation among the late adolescents in 6 institutions of higher learning in Malaysia. A total of 1572 students completed self-administered questionnaires between April and September 2013. Hierarchical multivariate logistic regression analyses stratified by gender were employed to identify the correlates of sexual initiation. The analyses were further adjusted by sampling weights. The overall prevalence of sexual initiation was 9.8% (95% confidence interval [CI] = 8.3-11.6), 18.1% (95% CI = 15.1-21.5) among males, and 4.1% (95% CI = 2.9-5.9) among females. The risk factors identified in this study supported the influence of the individual, family, and peer factors in the social-ecological model on adolescents' behaviors. The findings suggest the need for risk-reduction strategies aimed at the individual, family, and peer levels as well as the importance of gender-specific focus in assuring better outcomes.

    Glob J Health Sci, 2014 May;6(3):165-74.
    PMID: 24762359 DOI: 10.5539/gjhs.v6n3p165
    PURPOSE: This paper presents the findings of a cross-sectional survey on the risk and protective factors of premarital sexual behavior among rural female adolescents in Peninsular Malaysia.
    METHODS: We investigated data on 770 female respondents aged 13-17 years in rural areas to identify predictive factors for premarital sexual intercourse. Data were analyzed using bivariate and multivariate regression. Specific socio-demographic factors, psychological and family domains, peer delinquency, and knowledge and attitudes about sexuality were considered in risky sexual behaviors in rural Malay girls. The effects of other covariates for premarital sexual intercourse were controlled by logistic regression model.
    RESULTS: Of the 770 rural female students, about 3.2% of respondents reported experience of sexual intercourse in the past three months. Out of those sexually active girls, 36% were 17 years old and 20% stated having sexual intercourse with more than one partner, and 72% did not use contraception during the most recent sexual intercourse. Midnight activities, peer-sexual disorder, self-evaluation, and attitude toward sexual health were significant predictors of sexual intercourse in rural girls in Malaysia.
    CONCLUSION: The finding highlights the impact of psychological factors and peer group influences on the challenges of premarital sexual behavior among rural girls and the notion of school-based sexual health education for adolescents. This study triggers other researchers take into account a comprehensive view of protective factors operating in adolescents' risky sexual behaviors in Asian culture seeing that family domain variables, unexpectedly, exerted no predicting influence on sexually active female teens in rural areas in Malaysia.

    Hepatitis C infection is a global public health problem. This study was designed to identify the risk factors associated with hepatitis C infection among adult patients in Kedah state, Malaysia. A matched, hospital-based, case-control study was conducted at a tertiary hospital. Cases were adult (aged ≥ 18 years) patients with positive serology test results for hepatitis C virus antibody and detectable hepatitis C virus RNA from January 2015 to December 2018, and controls were age-, sex- and ethnicity-matched patients who were not infected with hepatitis C virus. Self-administered questionnaires were used to collect data on demographic characteristics and previous exposure to selected risk factors among the study participants. Associations between hepatitis C and demographic and risk factors were assessed using univariable and multivariable logistic regression analyses. A total of 255 case-control patient pairs were enrolled. The multivariable analysis indicated that having a history of blood or blood product transfusion before 1992 (adjusted odds ratio [AOR] = 6.99, 95% confidence interval [CI]: 3.73-13.81), injection drug use (AOR = 6.60, 95% CI: 3.66-12.43), imprisonment (AOR = 4.58, 95% CI: 1.62-16.40), tattooing (AOR = 3.73, 95% CI: 1.37-12.00), having more than one sexual partner (AOR = 2.06, 95% CI: 1.16-3.69), piercing (AOR = 1.71, 95% CI: 1.04-2.80), and having only secondary education (AOR = 1.92, 95% CI: 1.06-3.57) were independently associated with hepatitis C. No associations were found between health care occupation, needle-prick injury, surgical procedures, haemodialysis, acupuncture, cupping, or contact sports and hepatitis C infection. These findings demonstrate that hepatitis C risk is multifactorial. Having a history of blood or blood product transfusion before 1992, injection drug use, imprisonment, tattooing, having more than one sexual partner, piercing, and having only secondary education were associated with increased odds of hepatitis C.

  5. Fulltext Risk behaviour associated with HIV infection among drug abusers seen at the general Hospital, Kota Bharu, Kelantan
    Suarn S, Nor Adam M
    Med J Malaysia, 1993 Jun;48(2):117-23.
    PMID: 8350785
    Sixty-one serologically positive HIV infected drug abusers admitted to the Drug Ward, General Hospital, Kota Bharu, were interviewed for possible risk behaviour and AIDS awareness. Fifty-eight subjects were IV abusers while the other 3 were non-IV abusers. All the IV abusers had shared injecting equipment with no regard for sterility. There was non-usage of condoms among those sexually active. Though AIDS awareness was high, there was a lack of risk behaviour change. The drug abusers appear to be a problem group in HIV control measures. Educating the drug abusers and commitment by them to alter risk behaviour is needed.

    PMID: 25947820 DOI: 10.11646/zootaxa.3949.4.1
    The Sundaland species of the genus Dysphaea were studied using molecular and morphological methods. Four species are recognized: D. dimidiata Selys, D. lugens Selys, D. ulu spec. nov. (holotype ♂, from Borneo, Sarawak, Miri division, Upper Baram, Sungai Pejelai, Ulu Moh, 24 viii 2014; deposited in RMNH) and D. vanida spec. nov. (holotype ♂, from Thailand, Ranong province, Khlong Nakha, Khlong Bang Man, 12-13 v 1999; deposited in RMNH). The four species are described and illustrated for both sexes, with keys provided. The type specimens of the four Dysphaea taxa named by E. de Selys Longchamps, i.e. dimidiata, limbata, semilimbata and lugens, were studied and their taxonomic status is discussed. Lectotypes are designated for D. dimidiata and D. limbata. D. dimidiata is recorded from Palawan (the Philippines) for the first time. A molecular analysis using three markers (COI, 16S and 28S) is presented. This includes specimens of three Sundaland species of the genus (D. lugens missing) and two congeners from other regions (D. basi-tincta and D. gloriosa). Notes and photographs of the male holotype of D. walli Fraser (from Maymyo, Burma) are provided.

    PMID: 12288933
    PIP: Pink Triangle, the only community-based group in Malaysia which works with men who have sex with men, took initial steps in August 1992 to establish a self-help project for people who are HIV-seropositive. Supporting people who are HIV-positive and fighting for their rights is new in Malaysia. The group has thus far been publicized through its public education events, hospitals, and other nongovernmental organizations. For the first time, information is being published specifically by and for people living with HIV/AIDS. The project also has a phone line to allow people to speak anonymously with someone who shares their experience. Many callers are men who have sex with men in the social context of intense prejudice and discrimination. Afraid to openly acknowledge their sexuality with strangers, the callers have yet to accede to meeting each other face-to-face in a group setting. The author notes in closing that Pink Triangle must be realistic about what can be achieved in Malaysia and allow the group to develop according to people's needs and not on the basis of a model imported from outside of the country.

  8. Resolution of Female Sexual Dysfunction (FSD) Among the Obese Multiethnic Malaysian Women Now a Reality with Bariatric Surgery: a Prospective Pilot Study in Malaysia
    Lechmiannandan S, Panirselvam M, Muninathan P, Hussin N, Rajan R, Sidi H, et al.
    Obes Surg, 2019 05;29(5):1571-1575.
    PMID: 30706310 DOI: 10.1007/s11695-019-03722-w
    INTRODUCTION: Female sexual dysfunction (FSD) among the obese women is often under diagnosed and ignored especially in Malaysia, a nation of conservative multiethnic society. There are only a few studies on FSD resolution post-bariatric surgery. The objective was to identify the rate and resolution or improvement of FSD, among obese multiethnic Malaysian women post-bariatric surgery.

    MATERIAL AND METHODS: This is a prospective study of women undergoing bariatric surgery, between May 2017 and April 2018. FSD was diagnosed using the Malay version of Female Sexual Function Index (MVFSFI) questionnaire. Patients filled up the questionnaire before and 6 months after surgery. Association between BMI reduction and FSFI score improvement was measured using Fisher's exact test. Outcomes between types of surgery (sleeve gastrectomy and gastric bypass) was compared.

    RESULTS: Fifty-two women completed the study. The mean age was 38.77 ± 6.7. There were 44 (84.6%) Malay patients, 7 (13.5%) Indian patients, and 1 (1.9%) Chinese patient. There was a significant reduction in mean BMI, 39.89 ± 6.9 pre-surgery to 30.32 ± 5.4 post-surgery (p value sexual domains and should be considered as a management option in this group of women.

  9. Reproductive success of two male morphs in a free-ranging population of Bornean orangutans
    Tajima T, Malim TP, Inoue E
    Primates, 2018 Mar;59(2):127-133.
    PMID: 29387973 DOI: 10.1007/s10329-017-0648-1
    The reproductive success of male primates is not always associated with dominance status. For example, even though male orangutans exhibit intra-sexual dimorphism and clear dominance relationships exist among males, previous studies have reported that both morphs are able to sire offspring. The present study aimed to compare the reproductive success of two male morphs, and to determine whether unflanged males sired offspring in a free-ranging population of Bornean orangutans, using 12 microsatellite loci to determine the paternity of eight infants. A single flanged male sired most of the offspring from parous females, and an unflanged male sired a firstborn. This is consistent with our observation that the dominant flanged male showed little interest in nulliparous females, whereas the unflanged males frequently mated with them. This suggests that the dominant flanged male monopolizes the fertilization of parous females and that unflanged males take advantage of any mating opportunities that arise in the absence of the flanged male, even though the conception probability of nulliparous females is relatively low.

    PMID: 15581515
    The Sumatran rhinoceros (Dicerorhinus sumatrensis) is on the verge of extinction in Malaysia. At the Sumatran rhinoceros Conservation Centre in Sungai Dusun, the reproductive behaviour of two female and two male rhinoceroses were studied for 8-10 months during attempts to breed them in captivity. Due to the paucity of scientific information on the reproductive biology of the Sumatran rhinoceros, this study was conducted to obtain information on the reproductive behaviour of this species. The male rhino was introduced to a female rhino in the morning for 1-2 h daily in order to observe for behavioural oestrus. Observations were made on the signs of oestrus and mating behaviour. Oestrus was determined by receptivity towards the male and lasted about 24 h. Common signs of oestrus were an increase in frequency of urine spraying, tail raising or swinging, anogenital and other contacts. Although the males exhibited mounting, the inability of the male to achieve intromission was poor. The study demonstrated that the pattern of courtship and copulation of the captive Sumatran rhinos were comparable with those of other rhino species, reported previously by other scientists and flehmen reflex was also exhibited by the male Sumatran rhinos. In a captive breeding programme, it is recommended that only an oestral female is introduced into a male enclosure due to the male solitary behaviour and to avoid serious injuries inflicted onto the females.

    J Sex Med, 2014 Apr;11(4):956-965.
    PMID: 23845160 DOI: 10.1111/jsm.12246
    INTRODUCTION: Despite the high prevalence of sexual dysfunction among male schizophrenia patients, there is still a paucity of research on this area.
    AIMS: The study aims to determine the prevalence of sexual dysfunction and any association between male patients with schizophrenia in remission and the sociodemographic profile, medication, depression, anxiety, psychopathology of illness, body mass index, and waist circumference.
    METHODS: A cross-sectional study with nonprobability sampling method was conducted in a psychiatric outpatient clinic in Taiping Hospital (Perak, Malaysia) over a 7-month period. A total of 111 remitted male schizophrenia patients were recruited. The validated Malay version of the International Index of Erectile Function (Mal-IIEF-15) was administered to the patients and assessed over 4-week duration in the domains of erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction. Logistic regression analysis was employed.
    MAIN OUTCOME MEASURES: Prevalence and associated factors for sexual dysfunction in each domain are the main outcome measures.
    RESULTS: All five domains of sexual functioning in patients showed a high prevalence of dysfunction ranging from 78.4% to 97.1% with orgasmic dysfunction being the least impaired and intercourse satisfaction the worst impaired. Among the domains, only orgasmic dysfunction was significantly associated with race, i.e., Chinese at lower risk for impairment than the Malays (OR = 0.23; 95% CI: 0.07, 0.76; P = 0.018); education, i.e., patients with education higher than primary level were at higher risk for dysfunction (OR = 6.49; 95% CI: 1.32, 32.05; P = 0.022); and Positive and Negative Syndrome Scale (PANSS)-positive subscale, i.e., higher PANSS-positive score was a protective factor for orgasmic dysfunction (OR = 0.54; 95% CI: 0.33, 0.89; P = 0.015).
    CONCLUSIONS: The prevalence of sexual dysfunction was generally high. Malay patients and those with education higher than primary level were at higher risk for orgasmic dysfunction whereas higher PANSS-positive score was protective against the impairment. The high rate of sexual dysfunction in schizophrenia patients warrants a routine inquiry into patients' sexuality and the appropriate problems being addressed.

    Sains Malaysiana, 2016;45:79-86.
    A study was conducted to understand the relative abundance and growth of male and female Nemipterus furcosus population in the Pahang coastal water, Malaysia. The sampling was done monthly for a period of one year. A total of 1446 fish specimens were studied in this research. The results showed that male N. furcosus population was significantly more than female (p<0.01) N. furcosus population. The growth coefficient (b value) varied between 2.6808 and 3.2396 for male and 2.0926 and 3.2838 for female N. furcosus. The growth co-efficients of male N. furcosus were significantly different than the growth co-efficients of female N. furcosus in all months (p<0.05). They showed negative allometric growths in February- June and September. Female N. furcosus showed positive allometric growths in November-January and August. Isometric growths of female were observed only in October and July. As for male N. furcosus, negative allometric growths were observed in March-June, November and January. Male N. furcosus showed positive allometric growths in August, September, October, December and February. Male N. furcosus showed isometric growth only in July. The overall mean condition factor of male and female was statistically similar (p>0.05). The condition factor (K) ranged from 1.2559 to 1.3917 for male while 1.2503 to 1.3926 for female N. furcosus. Overall, higher mean condition factor was observed in smaller fish of both sexes. This study is useful for policy makers and fishery biologists for sustainable fishery management in the Pahang coastal water, Malaysia.

  13. Reactions to male-favouring versus female-favouring sex differences: A pre-registered experiment and Southeast Asian replication
    Stewart-Williams S, Chang CYM, Wong XL, Blackburn JD, Thomas AG
    Br J Psychol, 2021 May;112(2):389-411.
    PMID: 32701171 DOI: 10.1111/bjop.12463
    Two studies investigated (1) how people react to research describing a sex difference, depending on whether that difference favours males or females, and (2) how accurately people can predict how the average man and woman will react. In Study 1, Western participants (N = 492) viewed a fictional popular-science article describing either a male-favouring or a female-favouring sex difference (i.e., men/women draw better; women/men lie more). Both sexes reacted less positively to the male-favouring differences, judging the findings to be less important, less credible, and more offensive, harmful, and upsetting. Participants predicted that the average man and woman would react more positively to sex differences favouring their own sex. This was true of the average woman, although the level of own-sex favouritism was lower than participants predicted. It was not true, however, of the average man, who - like the average woman - reacted more positively to the female-favouring differences. Study 2 replicated these findings in a Southeast Asian sample (N = 336). Our results are consistent with the idea that both sexes are more protective of women than men, but that both exaggerate the level of same-sex favouritism within each sex - a misconception that could potentially harm relations between the sexes.

  15. Rarity of cancer of the cervix in the Malaysian Orang Asli despite the presence of known risk factors
    Sumithran E
    Cancer, 1977 Apr;39(4):1570-2.
    PMID: 856445
    Cancer of the cervix is exceedingly uncommon in the Malaysian Orang Asli (aborigine), despite the presence of factors associated with an increased risk of developing this malignancy. In only three patients was the diagnosis of carcinoma of the cervix established, out of a total of nearly 18,000 female inpatients, admitted to the Gombak Orang Asli Hospital over a 13-year period. Over this same period, 81 female patients were diagnosed as having cancer. Interviews with female Orang Asli patients show the presence of alleged risk factors for cervical cancer, including early age of first intercourse, multiparity and non-circumcision of husbands. The low incidence of cancer of the cervix in this aborigine community may be due to the strict moral code of the Orang Asli, limiting extramarital sexual activity and associated venereal infection.

    Sexuality as an important part of life has not been well studied in Malaysia, particularly among older adults. The main aim of this study was to investigate the racial and socioeconomic differences in sexual activity among older married Malaysians. Data for this study consisting of 1036 older married adults aged 60 years and older were obtained from the nationwide community-based cross-sectional survey entitled "Determinants of Wellness among Older Malaysian: A Health Promotion Perspective", conducted in 2010. Data were analyzed using SPSS version 21 for Windows. The results showed that 57.3% (95% CI: 54.3-60.3) of the respondents (61.6% of men and 50.6% of women) had engaged in sexual intercourse during the last 12 months. The adjusted multivariate logistic regression analysis revealed that ethnicity and educational attainment were independently and significantly associated with sexual activity, after controlling for the possible confounding effects of chronic medical conditions and demographic characteristics. The findings from this study do support the notion that sexuality is a lifelong need and cultural teachings and formal education may have important role in maintaining the quality of sexuality in later life.

    BMC Public Health, 2017 02 02;17(1):157.
    PMID: 28152993 DOI: 10.1186/s12889-016-3949-1
    BACKGROUND: From the Theory of Planned Behaviour perspective, sexual intention is determined by a permissive attitude, perception of social norms and perceived self-efficacy in performing sexual activity. The aim of this study was to develop and validate the Youth Sexual Intention Questionnaire (YSI-Q), which was designed to measure sexual intention among youths in Malaysia.

    METHODS: A total of 25 items were developed based on literature reviews encompassing four main constructs: sexual intention, attitude, social norms and self-efficacy. The YSI-Q then underwent a validation process that included content and face validity, exploratory factor analysis (EFA), reliability analysis, and confirmatory factor analysis (CFA). This study was conducted on unmarried youths aged 18 to 22 years who were studying in colleges around Klang Valley, Malaysia.

    RESULTS: EFA supported the four factor structure, but five items were removed due to incorrect placement or low factor loading (<0.60). Internal reliability using Cronbach's alpha ranged between 0.89 and 0.94. The CFA further confirmed the construct, convergent and discriminant validity of the YSI-Q with χ 2 = 392.43, df = 164, p sexual intention (five items), attitude (five items), social norms (six items) and self-efficacy (four items) of practicing sexual activity. YSI-Q was shown to be a reliable and valid tool to be used among Malaysian youths.

    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.

    It is socially natural that adolescents engage in romantic relationship. However, there are negative health implications when they are not properly monitored and guided. The engagement in unsafe sexual practices has been reported to cause various adverse health and social implications affecting Malaysian adolescents. To date, why adolescents engage in romantic relationship has remained understudied. Prior studies on adolescent romantic relationship mainly focused on the western context. Hence, the reported findings are deemed not applicable for the Malaysian population. There are insufficient data on the prevalence and determinants of adolescent romantic relationship within the Malaysian context. Thus, the current study aimed to identify the prevalence and determinants of romantic relationship among adolescents in Seremban, Negeri Sembilan, Malaysia. Adopting a cross-sectional research design, this study's self-administered questionnaire survey, which was conducted from 25 May 2021 to 5 June 2021 in residential areas that were part of the "Healthy Community Empowers the Nation" programme (KOSPEN), involved 396 adolescents who fulfilled the study's selection criteria. In terms of age, the respondents were of between 14 and 19 years old, with median age (IQR) of 19 (2). Adolescent romantic relationship in this study recorded prevalence of 24.1%, which was comparatively lower than that of the western countries. The results further revealed social media use (AOR: 2.162, 95% CI: 1.202-3.888, p = 0.01), pornography website surfing (AOR 2.748, 95% CI: 1.517-4.977, p = 0.001), poor SRH knowledge (AOR: 3.885, 95% CI: 2.144-7.040, p < 0.001), and depression (AOR: 2.830, 95% CI: 1.323-6.055, p = 0.007) as significant determinants of adolescent romantic relationship. Thus, this study demonstrated the significant role of social media use, pornography website surfing, SRH knowledge, and depression on adolescent romantic relationship. Further longitudinal studies to investigate the temporal relationships between depression and romantic relationship are recommended. The highly significant association between SRH knowledge and romantic relationship in this study suggests that strategies on improving the level of SRH knowledge among adolescents should be prioritised.

    INTRODUCTION: Despite being a widely used screening questionnaire, there is no consensus on the most appropriate measurement model for the Alcohol Use Disorders Identification Test (AUDIT). Furthermore, there have been limited studies on its measurement invariance across cross-cultural subgroups, genders, and sexual orientations.

    AIMS: The present study aimed to examine the fit of different measurement models for the AUDIT and its measurement invariance across a wide range of subgroups by country, language, gender, and sexual orientation.

    METHODS: Responses concerning past-year alcohol use from the participants of the cross-sectional International Sex Survey were considered (N = 62,943; Mage: 32.73; SD = 12.59). Confirmatory factor analysis, as well as measurement invariance tests were performed for 21 countries, 14 languages, three genders, and four sexual-orientation subgroups that met the minimum sample size requirement for inclusion in these analyses.

    RESULTS: A two-factor model with factors describing 'alcohol use' (items 1-3) and 'alcohol problems' (items 4-10) showed the best model fit across countries, languages, genders, and sexual orientations. For the former two, scalar and latent mean levels of invariance were reached considering different criteria. For gender and sexual orientation, a latent mean level of invariance was reached.

    CONCLUSIONS: In line with the two-factor model, the calculation of separate alcohol-use and alcohol-problem scores is recommended when using the AUDIT. The high levels of measurement invariance achieved for the AUDIT support its use in cross-cultural research, capable also of meaningful comparisons among genders and sexual orientations.
