ABSTRACT
Children less than 6 years old are the most vulnerable group to get harm from Environmental Tobacco Smoke (ETS) exposure, especially their respiratory system. To determine the prevalence of ETS exposure and its association with asthma like symptoms among children less than 6 years old. A cross sectional study was conducted in between January till April 2014 among parents with children less than 6 years old in Selangor, Malaysia. A total of 142 parents were selected by simple random sampling and data were collected using guided questionnaire on ETS exposure and asthma like symptoms (cough and wheeze) among their children. A total of 52.8% of children found to be exposed to ETS, and 43.7% were exposed from their father. ETS exposure significantly associated with cough without cold (adjusted OR=5.46, 95% CI 2.37, 12.61), dry cough at night (adjusted OR=3.74, 95%CI 1.41, 9.95) and cough upon physical activity (adjusted OR=3.08, 95% 1.07, 8.89) among these children. Children less than 6 years old are vulnerable to respiratory problem due to ETS exposure especially on cough symptoms. More strategies should be developing to reduce the exposure to ETS.
ABSTRACT
Soil-transmitted helminthiases are a public health problem in rural communities. A cross-sectional study of the prevalence and distribution of Ascaris lumbricoides, Trichuris trichiura and hookworm was conducted in 281 Orang Asli children (aborigines) aged between 2 and 15 years, from 8 Orang Asli villages in Selangor, Malaysia. All the children were infected with soil-transmitted helminthes, with 26.3% of the children infected either with A. lumbricoides, T. trichiura or hookworm and 72.6% having mixed infection. The overall prevalences of A. lumbricoides, T. trichiura and hookworm were 61.9, 98.2 and 37.0%, respectively. Approximately 19.0, 26.0 and 3.0% of the children had severe infection of ascariasis, trichuriasis and hookworm infection, respectively. The prevalences and mean egg per gram (epg) counts for A. lumbricoides and T. trichiura were not significantly dependent on age, therefore age-dependent convexity was not seen in this study. However, the results of this study reveal an age-dependent prevalence and mean epg count in children with hookworm infection. We conclude that ascariasis, trichuriasis and hookworm infection are still prevalent and therefore a public health concern in Orang Asli communities. Severe ascariasis and trichuriasis may lead to other health and medical problems.
