Objectives: The objectives of our study were to determine the mean age of onset of thelarche and menarche, to determine the ages of each stage of puberty and to investigate if there are any ethnic differences in these ages amongst female adolescents in Kuala Lumpur, Malaysia. Methods: This was a cross-sectional study involving three secondary schools in Cheras, Kuala Lumpur. A total of 730 students were recruited via stratified random sampling. Self-administered survey forms on menstruation and puberty were used. Results: Out of 730 recruited respondents, 385 (52.74%) completed the survey and informed consents were obtained from their parents/legal guardians. Our respondents’ ages ranged between 13 to 17 years old with the median (IQR) age of 14.00(2.00) years. With regards to ethnicity, 329 (85.50%) were Malay, 46 (11.90%) were Chinese, 9 (2.30%) were Indian and 1(0.30%) was a Bajau. The mean age for breast development (thelarche) and menarche were 11.72 ±1.10 and 11.97±1.11 years respectively. The majority, 363 (94.30%), out of 385 respondents had attained menarche. There appeared to be a later onset of puberty amongst Malays comparatively. Conclusion: The mean ages of pubertal onset and menarche amongst female adolescents in the Cheras area are similar to those reported worldwide.

Soil-transmitted helminth (STH) could possibly cause mild to severe health effects such as diarrhea, weakness, intestinal blood loss, and impaired cognitive development and growth. In Malaysia, previous studies depicted a high prevalence rate of STH was due to poor hygiene practice and low efficacies of anthelminthic drugs. This study was conducted to investigate hand hygiene practice and WASH criteria’s (Water, sanitation and hygiene) related to STH infection among two indigenous tribes in Peninsular Malaysia. A cross-sectional study was carried out to study the relationship among STH infection compared to water quality, sanitation, and hygiene conditions. A total of 190 individuals from two indigenous villages participated in the study, with ages ranging from 5 to 60 years old. In addition, Pearson’s Chisquare (X2) test was utilized to test the relationship among STH with demographic socioeconomic and behavioral factors. The confidence interval (CI) of 95% is used to estimate the precision of the odds ratio (OR). Multivariate logistic regression models were also used to identify the risk factors associated with STH infections. The overall findings indicated a prevalence rate of 72% for STH, and distributed mainly among children aged < 12 years. Furthermore, multivariate analyses using logistic regression revealed chronic health problems, incorrect hand washing, and walking bare footed were associated with STH infection. Overall results indicated high prevalence of STH among the indigenous villagers, which aligns with the published literature and proves to be a problem need to be addressed as neglected disease. Interestingly, there was a significant relationship between the presences of chronic diseases and STH infection, which prompted other questions the awareness needs to be educated and the simple and low-cost intervention on the proper way of hand washing may help to reduce STH infection in these indigenous communities.
