Introduction:Alcohol is a major factor that can affect many aspects of life. The prevalence of current drinker in Malaysia aged 13 years old and above was 7.7% as reported by NHMS 2015. Sabah was ranked the third in highest consumption of alcohol in Malaysia, at 18.4% after Kuala Lumpur 20.3% and Sarawak 19.7%. The aim of the study is to investigate prevalence of different types of drinkers and identify demographic characteristic of drinkers in Kota Kinabalu (KK). This study also aims to investigate the effectiveness of screening and brief intervention in reduction of alcohol consumption and risky drinking in KK. Methods: A cross-sectional study was done where the data were col-lected from seven different areas in KK, selected by stratified and simple randomized sampling. Alcohol Use Disorder Identification Test (AUDIT) questionnaire translated and validated in Malay version by Unit Terjemahan Universiti Malaya was used. AUDIT score was calculated and brief intervention was given accordingly and scoring was then repeated after three months. The intervention applied was based on Guideline on Risk Assessment and Primary In-tervention in Alcohol Harm, published by Ministry of Health Malaysia in 2010. Results: The age range of population studied is from 13 to 85 years old with 243 males and 230 females. Out of the 473 participants, 13.1% adolescent, 37.6% young adulthood, 36.4% middle adulthood and 12.9% in late adulthood. We observed that the male mean weight was 68.27±12.72kg versus 58.86±12.45kg mean weight in female. The prevalence of drinkers – 3.6% depen-dent drinkers, 22.2% high risk drinkers, 36.2% low risk drinker while the remaining 38.1% are abstainers. Majority of consumers were practicing low-risk drinking pattern which highlighted the need for prevention and harm minimiza-tion programme. Paired sample t-test shows that the decrease in AUDIT three months after intervention is statistically significant. Conclusion: This study conducted in KK suggests that screening coupled with brief intervention can help reduce alcohol misuse and risky drinking and should be practiced in all primary healthcare facilities.
