Previous studies have primarily focused on nurses, especially in hospital settings, leaving a gap in our understanding of staff in community health clinics with different work environments. Objectives: To determine the prevalence of low back pain and its associated occupational risk factors among healthcare workers in community health clinics. Methods: A cross-sectional study involving 360 healthcare workers in Kota Kinabalu district collected sociodemographic data, occupational characteristics, low back pain history, and psychological characteristics. Low back pain risk assessment was performed using the Rapid Entire Body Assessment (REBA) and BACKS tool. Results: Among 360 participants, 71.7% reported experiencing low back pain within the past 12 months. Significant associations were found by Chi-Square test between low back pain and the number of children, Body Mass Index (BMI), smoking status, manual handling, awkward postures, assisted lifting of heavy objects, and psychological factors. The findings highlight the high prevalence of LBP among healthcare workers and its association with various occupational factors. Implications for designing specific disease prevention programs to protect healthcare workers are considered, thus enabling them to maintain the highest level of care for the general public.

Material and Methods: Air samples of worker’s breathing zone were collected using personal air sampling pump and filter papers. Filter paper were then diluted and analyzed with Atomic Absorption Spectrophotometry (AAS). Workers urine was collected at the end of 8-hour work shift and analyzed with β-2-microglobulin ELISA Kit (IBL-Hamburg) and a microtiter reader. Meanwhile, creatinine levels were analyzed with creatinine test strips and Reflotron®. Results: Mean concentrations of suspended chromium compounds in air for the exposed group was 0.135±0.043µg/m3 while for the non-exposed group was 0.124±0.029µg/m3 . The mean level of urinary β-2-microglobulin per creatinine for the exposed group was 84.996±39.246µg/g while that of the comparative group was 61.365±21.609 µg/g. The concentrations of suspended chromium compounds were higher in the exposed group compared to the comparative group (Z=-2.444, p=0.015). β-2-microglobulin level was also higher in the exposed group compared to the non-exposed group (t=3.821, p=<0.001). However, there was no significant correlation between suspended chromium compounds in air and urinary β-2-microglobulin levels (r=0.080, p=0.457) among the respondents. A multiple stepwise regression analysis showed that the most influence variable or confounding factor to β-2-microglobulin level was the education year (β =-0.020, p=0.010). Conclusion: All respondents were exposed to concentrations of chromium below regulated limit. Years of education seemed to be a secondary factor that influenced β-2-microglobulin level.

In light of the COVID-19 crisis, municipal waste collectors are one of the most at-risk groups of SARS-Cov-2 exposure. Risk assessment included hazard identification, evaluation of existing control level at the workplace, estimation of likelihood and severity of hazard, risk determination, and control measure recommendations. Five waste collection activities were identified and reviewed. High-risk exposure includes collection of garbage, mechanical manipulation of compactor lorries and unloading of garbage at the disposal site. There is poor practice of personal hygiene and unestablished continuous monitoring of personal protective equipment supplies. The preventive measures in the waste collection industry are influenced by several factors. Until the preventive measures are adopted into practice and adapted according to each company's requirements, biolo...

Various factors were associated with burnout among doctors, but the factors vary in different countries. This study aimed to investigate the prevalence and associated risk factors of burnout among public service medical officers in Kota Kinabalu, Sabah, who were involved in combating the Covid-19 outbreaks. A cross-sectional study involving 201 medical officers working in all government hospitals and health clinics was carried out. Using the Copenhagen Burnout Inventory (CBI), the prevalence of personal-related and work-related burnout were 61.2% and 48.8% respectively, while the prevalence of client-related burnout was 39.8%. Working in different medical departments and the length of working experience were the significant associated risk factors of burnout among the doctors. Meanwhile,...

Medical education has been known as one of the most stressful academic curriculum. Hence, medical students may subjected to multiple psychological changes and challenges throughout the years of medical education. The aim of this study was to determine the prevalence of stress and its associated factors among medical students. This cross sectional study was conducted from April to May 2018 in medical school in Sabah. It involved 396 medical students through universal sampling. Self-administered questionnaires were used as an instrument for data collection. The questionnaires included were Sociodemographic Questionnaire, Depression, Anxiety and Stress Scales 21 (DASS-21) and Medical Student Stressors Questionnaire (MSSQ). Bivariate analysis (Chi Square test, Fisher’s Exact Test, Independent T test and Man-Whitney U test) were used to analyse the association. The response rate was...

This study aims to determine the concentration of urinary lead with serum creatinine and blood urea nitrogen in chronic kidney disease patients and to identify the influences of confounding factors and the blood pressure on the chronic kidney disease patients. Graphite Furnace Atomic Absorption Spectrometer was used to determine the urinary lead concentration. The differences and correlation of urinary lead with serum creatinine, blood urea nitrogen and diastolic blood pressure between the chronic kidney disease patients and control groups were assessed using Mann Whitney U and Spearman correlation tests. Our findings indicated a significantly higher urinary lead concentration in the chronic kidney disease group compared to the control group (p-=0.002). Nevertheless, there is...

The accident in the industry is a major contributor to the accident’s statistics. The Malaysian government is serious in preventing the accidents in the construction industry including in Sarawak. Both authorities such as DOSH and CIDB are responsible to monitor the development of the construction industry including the OSH implementation in the workplace. DOSH is providing a free service to construction player in terms of legislative compliance including the implementation of OSHMS, and CIDB is controlling the industry development by registering all construction workers. CIDB is also providing site safety induction to the construction workers in order to create safety awareness for workers. However, the number of accidents reported is quite alarming. It is believed that the occurrence of an accident is due to the attitu...

The incidence of malaria is the lowest (0.05/1,000 population) in Penampang districts of Sabah. In June 26, 2012, two Plasmodium falciparum malaria cases were notified to public health department from a village in Penampang. Immediate investigation was initiated to identify the risk factors and to institute control measures. We performed active case finding by asking household members of all houses in the village regarding malaria symptoms and by examining blood smears. Environmental investigation was performed by collecting samples to detect mosquito breeding sites and to identify malaria transmitting vector mosquitoes. A case-control study with a ratio of 1:4 (11 cases and 44 controls) was conducted using self-administered questionnaire. The microscopic examination of blood smear for malarial parasite and entomology sampling was carried out. The malarial attack rate was 2.3%, 6/11 sm...
