This is a review of research done in the area of substance abuse in Malaysia. There were 109 articles related to substance abuse found in a search through a database dedicated to indexing all original data relevant to medicine published in Malaysia between the years 2000-2013. Only 39 articles were reviewed, and case series, case report, reviews and reports were excluded. Research reviewed include the epidemiology of substance abuse, genetics, treatment and its relation to health behaviour, and health management. Studies have shown that more males than females use drugs. There was also a high prevalence of blood-bourne virus diseases and sexually transmitted diseases among drug users. Two studies showed some genetic polymorphism (Cyp 3a4 gene and FAAH Pro129Thr) among heroin and amphetamine users respectively that may contribute to drug dependence. Study on pharmacological treatment for substance abuse were limited to methadone and it was shown to improve the quality of life of heroin dependant patients. Alternative treatments such as acupunture and spiritual approach play a role in the management of substance abuse. Data also showed that treatment centres for substance abuse are lacking facilities for screening, assessment and treatment for medical illness related to substance use, e.g. Hepatitis C and tuberculosis. Studies on the effectiveness of current drug rehabilitation centres were inconclusive.

Objective: To investigate the prevalence of genital arousal disorder and the potential risk factors that may impair genital arousal among women at a primary care setting in Malaysia. Methods: A validated questionnaire for sexual function was used to assess genital arousal function. A total of 230 married women aged 18–70 years old participated in this study. Their sociodemographic and marital profiles were compared between those who had genital arousal disorder and those who did not. The risk factors were examined. Results: The prevalence of genital arousal disorder in the primary care population was 50.4% (116/230). Women with genital arousal disorder were found to be significantly higher in groups of more than 45 years old (p<.001), among the non-Malay (p=.01), those with lower academic status (p=.025), those married for more than 14 years (p=.001), those married to older husbands (aged>55) (p =.001), those having 4 children or more (p=.028), those having less sexual intercourse (less than 1–2 times a week) (p=.001), and those at post-menopausal state (p=.002). There was no significant difference between these two groups in term of salary (p=.29), suffering from medical problems (p=.32), dysmenorrhea (p=.95), menarche (p=.5) and hormonal replacement therapy (p=.6). Conclusion: Women with infrequent sexual intercourse are less likely to be sexually aroused (OR=0.29, 95% CI: 0.11-0.74).

The aim of the study was to compare sexual functioning among Malaysian women in a primary care setting between those with a low and high frequency sexual intercourse.Across-sectional study on 230 married Malaysian women in a primary-care setting was conducted at the Bandar Tun Razak Clinic, Cheras. A validated Malay version of Female Sexual Function Index questionnaire (MVFSFI) was used to assess the sexual functioning profiles among women with low and high sexual activity. The percentage of women who had sexual intercourse 3-4 times a week, 1-2 times a week and < 1-2 times a month were 13.4%, 44.3 % and 42.4 % respectively. Women with a low frequency of sexual intercourse (Low SI) tended to suffer from more sexual dysfunction, (χ²=28.98, p < 0.001) compared to those with a high frequency of sexual intercourse (High SI) group. Women who were less sexually active (having low frequency intercourse, ie. ≤ 1 – 2 times per week) were found to be less sexually aroused (χ²= 25.9, p< 0.001), less orgasmic (χ²=19.8, p< 0.001), less lubricated during sexual activity (χ²=11.1, p< 0.001), complain of sexual pain (χ²=4.3, p = 0.033) and feels less satisfied sexually (χ²=12.6, p< 0.001).The problem of female sexual dysfunction (FSD) in the Malaysian primary care population with low sexual activity needs to be addressed.

Major Depressive Disorder (MDD) is substantially higher in people seeking Methadone Maintenance Therapy (MMT) as compared to the normal population. Erectile Dysfunction (ED) is one of the side effects of Methadone Maintenance Therapy (MMT) which is rarely explored as it is regarded as a sensitive topic. This study aims to determine the prevalence of MDD and its association with ED among MMT clients. A cross-sectional study was conducted involving 160 subjects who attended the Methadone outpatient clinic. The clients were given Patient Health Questionnaire-9 to screen for depressive symptoms and MINI International Neuropsychiatric Interview to diagnose MDD. ED was diagnosed using the 5-item International Index of Erectile Function. The results showed the prevalence of depression in clients on MMT was 30.6% and the prevalence of ED was 72.5%. On multivariate analyses, there were significant associations between ED with depression (P<0.05). Smoking also was found to be contributed to depression. Sociodemographic factors, comorbid medical illnesses, and illicit substance use were found to have no associations with depression. Therefore, given the prevalence of MDD and ED in MMT clients was high, routine assessment of depressive symptoms and sexual function in clients on methadone should be done to minimize their negative impact on the clients
