    Cr0ss»sectional studies on lung functions of 100 smokers and 100 non-smokers was conducted among a university student population. The objectives of the studies were to determine the correlation between the lung functions with smoking frequency and duration among smokers as well as to compare the lung functions with non-smokers. The smokers’ mean age was 20.74 years, their smoking initiation age was 16.18 years, the smoking duration was 4.41 years and the smoking frequency was 8.72 cigarettes per day. Among smokers, signqicant inverse correlation was shown between FEV] predicted and the smoking frequency (number of cigarette per day) (ri-0.241, p=0.016). Multiple regression confirmed the relationship between FEV]% predicted with respondent’s age (p=0.013) and smoking frequency (p=0.002), FVC% predicted with age (p=0.005) and smoking frequency (p=0.009). The FEV;/FVC% predicted was signyicantly related to phlegm symptoms (p=0.03), while the FEFZ5.y5% predicted was signdicantly related to age (p=0.005), height (p=0.043) and smoking duration (p=0.046). The lung functions (FEV1% predicted, FVC% predicted and FEV]/FVC% predicted ) for smokers were not statistically dyferent from non-smokers. This study showed that the lung functions for the smokers were still quite normal due to their short smoking duration, their low number of cigarette smoked per day and their young age.

    BACKGROUND: With the high prevalence of hypertension, it is important to determine its predictors early. The aim of this study was to determine the association between blood pressure with anthropometric indices and birth weight among a population of Malay adolescents in Kuala Lumpur.

    DESIGN AND METHODS: This cross-sectional study was carried out among 254 primary and secondary school adolescents aged 10 to 16 years. Anthropometric measurements and blood pressure were determined through standardized protocols, while participants' birth weight was obtained from birth certificate. Body mass index (BMI), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR) and a body shape index (ABSI) were calculated.

    RESULTS: Boys had significantly higher weight, height, WC, WHtR and systolic blood pressure (SBP) than girls (p  +1SD had higher odds of being prehypertensive or hypertensive (aOR 8.97; 95% CI 3.16, 25.48), followed by participants with WC ≥ 90th percentile (aOR 6.31; 95% CI 2.48, 16.01) and participants with WHtR > 0.5 (aOR 5.10; 95% CI 2.05, 12.69). Multiple linear regression showed BMI was positively associated with both SBP and DBP. No significant association was found between birth weight and BP.

    CONCLUSION: BMI had the best predictive ability for SBP and DBP. These findings strongly emphasize the importance of primary prevention of hypertension in adolescents, especially among those with high BMI.
