Each year, influenza A infections have caused tremendous death rate as high as 300,000-500,000 globally. Although
there are effective anti-influenza agents and vaccines, high mutational rate among influenza A viruses renders dramatic
decline in the effectiveness of anti-influenza agents or vaccines in certain individuals. The situation is further complicated
by limitations in influenza vaccine production, for instance, long production period, limited vaccine capacity and lack
of cross-protection against various influenza A virus strains. To solve these issues, development of universal influenza
vaccine based on conserved antigens such as non-stuctural protein 1 (NS1) has been endeavoured. NS1 protein is highly
conserved in all influenza A virus strains known by far, produced abundantly on infected cell surfaces and responsible for
maintaining virulence. Furthermore, cytotoxic T-lymphocytes that are active against NS1 were also reported to be able
to avoid shedding of influenza in hosts. To better inhibit influenza infections, oral immunization has long been proposed
due to feasibility of this method to be implemented and safer for recipients while able to target influenza A viruses from
the entry point. Lactobacillus has been vastly studied for its roles as bacterial carrier in oral vaccine development due
to its significant probiotic properties. For examples, stimulation of immune responses in oral and airway mucosal layers,
high colonization in oral and airway mucosal layers and great natural adjuvant effects. In this light, influenza universal
oral vaccine developed using NS1 dan Lactobacillus should be further studied in influenza oral vaccine design.
Patient’s appointment compliance refers to the willingness and ability of a patient to attend to their scheduled clinical appointment. Failure to do so have various consequences, especially so for a teaching clinic such as the Optometry Clinic, Universiti Kebangsaan Malaysia (UKM). The percentage of appoinment compliance at the Optometry Clinic was analysed from September to December 2015. Compliance rate was categorised based on clinic type and session, and on patient’s gender and ethnicity. Attendance compliance was around 60% for the Primary Care Clinic. It increased to 70% for patients with vision problems who where referred to specialty clinics i.e. Low Vision and Paediatric Clinics. Clinic day and session did not influence compliance significanly (p > 0.05). Patient’s gender and ethnicity did not influence compliance significantly as well but those of Indian ethnicity consistently showed the lowest appointment compliance rates. A protocol should be developed to increase the rate of patients’ appoinment compliance. This would then maximise productivity of students and clinic staff and optimise the clinic’s resources. The cost of each clinical session could be informed to the patients, even when the cost is not borne by them.

Malaysia was ranked at 148 by World Health Organization (WHO) in suicide statistic for 2012, where males had a higher
tendency to commit suicide, recording a 4.7 per 100,000 in comparison to female (1.5 per 100,000). As hanging is one of
the most common methods to commit suicide, this retrospective study was conducted to observe the incidence of suicide
by hanging in Klang Valley from four different hospitals. The current study is conducted to provide local database of
suicide occurrence by hanging in Klang Valley. A total of 893 suicide cases by hanging from 2007 to 2016 were recorded
from post mortem records and analysed. Suicide rates in Klang Valley showed a rising trend from 2007 to 2016. Males
from age group 30 to 34 years old and females from 20 to 24 years old have the highest number of suicide fatalities
compared to other age groups. Meanwhile, fatalities from the age group of 10 to 14 years old and 80 years old and above
showed similar result which is only 7%. 78% of the fatalities were recognized as Malaysian and half of them were Indian.
Majority of the victims/cases (45%) who committed suicide by hanging are of Hindu religious denomination. Non-citizen
in Malaysia that have the highest suicide rates were from Nepal, Indonesia and Myanmar. Victims also committed suicide
more during the day and the peak hours being at 12.00 pm to 5.59 pm.
The present study discussed functional reorganization and alteration in respond to the slow-growing tumour,
hemangiopericytoma in the occipital cortex. Visual evoked field (VEF) and auditory evoked field (AEF) using
magnetoencephalography (MEG) was used to evaluate the source localization and brain activity. Results of VEF source
localization show a typical brain waves. Brain activity of the occipital lobe demonstrate low activation in the ipsilateral
to the tumour. However, result shows the activation on the contralateral hemisphere was high and bigger in activation
volume. AEF result shows an identical source localization and both side of the temporal lobe are activated. This result
suggests that there is a positive plasticity in auditory cortex and slow-growing tumour can induce functional reorganization
and alteration to the brain.
Traditionally, Clinacanthus nutans (CN) or locally named as ‘Belalai Gajah’ is one of the herbal plant claimed to be
able to treat cancer. The aimd of this study are to extract, isolate and characterize the active anticancer compound
from CN and to determine the mode of cell death induced by the compound. Bioassay guided fractionation was done on
the CN extract by using column chromatography. The cytotoxicity activities of these fractions toward HeLA cells were
examined by MTT assay. The nuclear morphology was examined by Hoechst 33258 staining and the cell cycle arrest
was evaluated by propium iodide staining using flow cytometry. The presence of active compound in the chosen fraction
was determined by Liquid Chromatography Mass Spectrometry (LCMS). Out of 16 fractions collected, Fraction 11(F11)
showed the lowest IC50 value with 27 ± 2.6 µg/mL. The value of IC50 for F11 towards normal cell, NIH 3T3 cell and L929
cell, were 70 ± 4.0 µg/mL and 45 ± 1.5 µg/mL respectively. These values were higher than tamoxifen, therefore indicating
that tamoxifen is more toxic towards normal cells compared to F11. Nuclear morphology of HeLA cell displayed DNA
fragmentation, nuclear condensation and formation of apoptotic bodies upon treatment with F11 for 24 hours. The cell
cycle distribution of HeLA cell treated with F11 was arrested at G1 phase. The active compound identified to potentially
possess the anticancer property is 19-Oxo-all-trans-retinoic acid. In conclusion, 19-Oxo-all-trans-retinoic acids from
F11 of the CN extract, is a potential anticancer agent for cervical cancer.
Doctor shopping increases health economic burden and morbidities. Its prevalence and predisposing factors have to be identified in order to formulate preventive measures. We aimed to determine the prevalence of doctor shopping, its reasons and predisposing factors by conducting a cross sectional study of new patients at the Dermatology Clinic, Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Doctor shopping was defined as having consultation with ≥3 healthcare providers without a referral for the same illness prior to the patients’ visit to UKMMC. Reasons and contributing factors were classified as disease, healthcare provider, logistic and cost related. Data was collected by a face to face interview. Dermatology Life Quality Index (DLQI) questionnaire determined disease impact on the patients. A total of 58 (55.8%) female and 46 (44.2%) male patients participated. Referral was patient-initiated in 51.9% while 40.4% were doctor shopping. Age, gender, ethnicity, income, occupation and type of health finance provider were not associated with this behaviour. About 95% doctor shopped due to disease factors: searching for a cure (95.2%), lack of improvement (88.1%), worsening disease (50.0%), dissatisfaction with treatment (31.0%), seeking other opinions (26.2%) and exploring treatment options (26.2%). Impaired DLQI (OR 1.17; 95% CI 1.08,1.38), p 0.04, and disease related factors (OR 6.57; 95% CI 1.52, 7.72), p 0.041 were significant independent risk factors. Doctor shopping is very common among our patients. Reasons and predisposing factors are predominantly disease related. Patient education and counselling is important in management of dermatological diseases to prevent doctor shopping.
This research aimed to evaluate the oral hygiene status in fixed orthodontic appliance patients when using two different slim bristles toothbrushes and to assess patients’ toothbrush perception.Twenty six fixed orthodontic appliance patients participated in the six weeks prospective, crossover clinical trial. All patients used two different slim bristles toothbrushes (Toothbrush A and Toothbrush B) for two weeks each with a washout period in between. Gingival health and plaque value were assessed based on Löe & Silness Gingival Index and Silness & Löe Plaque Index at baseline, week 2, week 4 (washout) and week 6. At the end of the trial, patients’ toothbrush perception was assessed through questionnaire. All data were analysed using SPSS version 22.The mean age of the patients was 21.5 ± 4.3 years, with female predominant (n = 17, 65.4%). More than half were Malay (n = 15, 57.7%) and had tertiary education (n = 14, 53.8%). Patients could achieve good oral hygiene when using Toothbrush A (65.4%) and Toothbrush B (69.2%). However, the occurrence of gingivitis was significantly higher when using Toothbrush A (OR = 1.889, 95% CI = 1.207-2.957, p value < 0.05). Toothbrush B was felt to clean better (n = 14, 53.8%) while Toothbrush A was perceived to be easier to use (n = 14, 53.8%). Both toothbrushes maintained patients’ oral hygiene status. However, when using Toothbrush B, oral health status was better as it significantly reduced gingivitis occurrence compared to Toothbrush A. As for the toothbrush perception, most patients preferred Toothbrush A to be taken home.
The assessment of exclusive breastfeeding is important to invest the efforts to promote and support breastfeeding practices. Hence this study was carried out to compare breastfeeding practices among mothers using deuterium dose to mother technique with maternal recall breastfeeding practice. A total of 30 mother-infant pairs from a university hospital and government health clinics in Klang Valley participated and completed the study. Mother-infant pairs were recruited into the study when infants were aged 3 months ± 1 week. Anthropometric measurements (height, weight, waist circumference for mother; length and weight for infant) were carried out. Socio-demographic questionnaire was self-administered while breastfeeding practices were interview administered using maternal recall breastfeeding practice questionnaire (MRBF). This was followed by baseline saliva collection of mother-infant pairs before dose and 6 days after mothers were given 30 ± 0.01 g of D2 O. The post dose saliva sample of mother-infant pairs were collected 6 times at day 1,2,3,4,13 and 14.The results showed that majority of mothers (57%) were university graduates but majority were stay at home mothers. Meanwhile, mothers had BMI with mean 25 ± 4 kg/m2 . The results from MRBF questionnaire showed that all mothers were practicing exclusive breastfeeding and their infant never received any water sources other than their breast milk. However, the deuterium dose to mother technique revealed only 3% of mothers were actually practicing exclusive breastfeeding. From the isotopic data, the calculated mean intake of milk was 721 ± 243 g/day while the mean non-milk oral intake of 122 ± 22 g/ day. In contrast exclusive breastfeeding infants received only 10 g/day non milk oral intake, demonstrating exclusive breastfeeding practice of mothers. There were different breastfeeding practice reported from mother using deuterium oxide dose to mother technique with maternal recall breastfeeding practice.

Compliance rate towards consumption of oral nutritional supplement (ONS) is low among geriatric patients. Thus, this study aimed to examine factors affecting low compliance of ONS intake among a sample of geriatric patients. A cross-sectional survey was carried out involving 30 geriatric patients being prescribed with ONS during their stay in Hospital Kuala Lumpur. Information on compliance rate and influencing factors were collected through interview and observation. Nutritional status was assessed using anthropometry and Patient Generated Subjective Global Assessment (PG-SGA). 50.0% subjects were underweight and 70.0% and 30.0% were moderate and severely malnourished, respectively. A total of 43.3% were categorised as low, 53.4% medium and 3.3% high compliance towards consumption of ONS. Most of the subjects with low compliance agreed expressed that they need more nursing support (53.8%). Less than half perceived they had been given the needed nursing support (44.4%), and with respect to ONS: knowledgeable (38.5%), timely given (37.5%), understood the importance (35.7%), were able to finish it (35.0%), well-aware of the reasons of prescription (33.3%), satisfied with its taste (33.3%), received suitable volume (33.3%), satisfied with the texture (31.6%), and received suitable frequency (28.6%). In conclusion, approximately 40% of subjects had low compliance towards ONS. Awareness and nursing support were important factors associated with low compliance. There is a need to ensure adequate nursing support and education been given to patients prescribed with ONS in order to increase the compliance rate.
In Malaysia, drug addiction has been a big threat since 1983. As of by latest statistic by National Anti-Drug Agency in 2016, the number of drug abusers in Malaysia was 30846. Acknowledging the importance of drug abuse and relapse as a public health issue, Malaysian government had implemented Harm Reduction Programme .Under this programme, Methadone Maintenance Therapy (MMT) was launched in Oct 2005. This study was undertaken to evaluate the effectiveness of MMT programme among opiate dependent individuals in their daily life. In this study, 100 individuals from the Ministry of Health (MoH), Klinik Kesihatan Bayan Lepas (Bayan Lepas Health Clinic) and Agensi Anti-Dadah Kebangsaan (National Anti-Drug Agency) in Telok Bahang were involved. The subjects were interviewed with WHOQOL BREF questionnaires before joining the MMT programme and also after minimum 4 months of joining MMT. Results obtained were used for comparing life style implications among methadone patients before and after joining the MMT programme. Subjects were predominantly of Malay ethnicity (82%). Subjects were mostly aged between 51 to 60 years old (34%). Paired t-test was done on the WHOQOL scores at baseline (before MMT) and after minimum of 4 months enrolment for all four domains. Each domain showed significant improvement in QOL (P < 0.05).The highest improvement was shown in the psychology domain with the mean value increment of 15.13 ± 17.49. Physical domain showed the least improvement with the mean value of 9.39 ± 16.21.This study has proven that MMT have highly contributed to improvement of quality of life among MMT clients in Klinik Kesihatan Bayan Lepas and AADK Telok Bahang.
Sex determination is one of the basic components in victim identification. This study aims to ascertain the sex of an individual from burnt teeth samples exposed at different temperature and time through nested polymerase chain reaction (PCR) on the amelogenin (AMEL) sex marker, to calculate the specificity and sensitivity, and to compare with previous relevant studies. A total of 17 teeth samples was subjected to burning at different temperatures ranging from 100°C to 500°C, at 2 to 10 minutes. The whole tooth was used for deoxyribonucleic acid (DNA) extraction by phenol-chloroform method. All samples were quantified for DNA concentration and then analyzed with nested PCR using two pairs of AMEL primer and results of sex typing were recorded. Out of 17 samples, genomic DNA extracted from 6 samples have concentrations ranging from 27.3 – 130.6 ng/μL. Nested PCR could amplify 16 samples for AMEL gene. Sex typing using AMEL gene showed 76.47% accuracy. Sensitivity of AMEL primer was increased from 6.67% to 63.64% using nested PCR technique; specificity of both external and internal primer was reported at 100%. Nested PCR of AMEL gene proved to be a suitable method for unequivocal determination of sex from degraded DNA samples.
Binge eating (BE) behaviour is associated with obesity and eating disorders. This cross-sectional study investigates BE behaviour and its relationship with nutrition-related factors among university students. A total of 170 (69% females) university students in Malaysia aged 19 to 24 years participated in this study. BE behaviour was assessed with the use of Binge Eating Scale (BES) questionnaire. Socio-demographic background and nutritional status (anthropometric measurements, body mass index (BMI) and dietary intake) were also measured. BE behaviour reported by 10% percent of the participants. BE behaviour was associated with increased energy intake, elevated BMI and sex (Adjusted R2 = 0.116, p < 0.001). Differences in sex-specific factors in predicting the risk of BE behaviour were evident. In male participants, an increased in energy intake, elevated BMI and had a higher waist circumference associated with the risk of BE behaviour (Adjusted R2 = 0.411, p < 0.001). In female participants, only a higher waist circumference associated with BE behaviour (Adjusted R2 = 0.028, p < 0.05). The finding suggests that understanding sex-specific factors are necessary to prevent BE. These are the potential targets for tailored eating behaviour intervention among university students.
Monosodium glutamate (MSG) is widely used as an additive in food. Excess consumption of MSG was reported to cause oxidative stress on brain, liver and renal resulted in increased production of reactive oxygen species (ROS). This study aims to determine the biochemical and histological effects of low dose MSG on the liver of adult male Sprague-Dawley rats. Animals (n = 6 per group) were randomly divided into three groups with two treatment groups: 60 mg/kg (MSG60) and 120 mg/kg (MSG120), and one control group (distilled water). The substances were administered to the rats via force feeding for 28 consecutive days. On day 29, all rats were killed, and liver tissues were biopsied for the biochemical (total protein, liver enzymes, and the status of oxidative stress) and histological analysis. The total protein appeared significantly decreased (p < 0.05) while alanine aminotransferase (ALT) and aspartate aminotransferase (AST) demonstrated a significant increased (p < 0.05) in the MSG120 treatment group as compared to the control group. Malondialdehyde (MDA) levels and the antioxidant levels of superoxide dismutase (SOD) were significantly increase (p < 0.05) in the MSG120 group as compared to the MSG60 and control groups. The histological findings revealed changes to normal liver architecture and accumulation of red blood cells in the central veins in both MSG groups. This study indicates that the MSG consumption at a dose of 120 mg/kg may ALTer the biochemical and histological parameters of the liver.
Sekolah tahfiz merupakan institusi yang mengkhususkan pendidikan kepada pelajar yang boleh menghafaz serta mengingati keseluruhan al-Quran. Aktiviti menghafaz al-Quran dengan teknik pengucapan berulang kali akan membantu meningkatkan keupayaan otak untuk memproses, mengingati maklumat dan membina memori. Kehadiran logam berat akan memberi kesan kepada sistem saraf serta mengganggu fungsi sistem saraf pusat dan periferi di mana akan seterusnya menyebabkan berlakunya kecelaan fungsi mental dan kognitif. Keupayaan untuk belajar, mengingati atau menghafaz, penggunaan bahasa dan untuk memahami sesuatu akan terganggu serta mengurangkan IQ dan perhatian. Kajian keratan rentas telah dilakukan bagi mengukur dan mengenal pasti hubungan di antara tahap logam berat, hafazan al-Quran dan tahap kecerdasan (IQ) dalam kalangan pelajar di sekolah tahfiz berbanding sekolah bukan tahfiz terpilih di Selangor. Kepekatan logam berat ditentukan melalui analisa sampel kuku dan rambut pelajar dengan menggunakan Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Ujian kecerdasan Wechsler Adult Intelligence Scale Edisi Kedua (WASI-II) digunakan untuk mengukur IQ pelajar. Borang soal selidik yang digunakan untuk mengumpulkan data demografik dianalisa menggunakan SPSS versi 23.0. Berdasarkan ujian korelasi Pearson yang dilakukan, terdapat korelasi negatif yang sangat lemah tetapi signifikan antara logam mangan dalam sampel rambut dengan tahap hafazan al-Quran (r = -0.178, p = 0.017). Selain itu, terdapat korelasi positif yang lemah tetapi signifikan antara IQ dengan tahap hafazan al-Quran (r = 0.375, p = < 0.001). Kesimpulannya, semakin tinggi kepekatan logam mangan akan menyebabkan penurunan tahap hafazan al-Quran serta apabila semakin tinggi tahap hafazan al-Quran akan menyebabkan tahap kecerdasan (IQ) juga semakin meningkat.
Wood is one of the most common material found in homes and industrial fires, particularly in Malaysia. The abundance of different types of wood used to build structures, frames, furniture and others are important to take note as wood is a conducive material that can be used to initiate and propagate a fire, particularly in forensic fire cases. This study was conducted to provide the volatile chemical fingerprint of burnt Merbau (Intsia sp.) wood using gas chromatographymass spectrometry (GC-MS). The wood samples were prepared under two conditions; fully dried and partially dried. Six study replications of each condition were burnt outdoors and underwent an extraction process using activated carbon tablets. The tablets were incubated in an oven for 16 hours at 80ºC. Next, the tablets were desorbed in two different types of solvent; pentane and ethanol. The pentane- and ethanol-desorbed volatile products were then introduced into the GC-MS. Volatile organic compounds obtained across both conditions were in the range of volatile acids, aromatics and its derivatives, D-glucopyranose, phenolic derivatives and cycloalkane. The compounds emitted by fully and partially dried Merbau wood samples were similar, differing only in the absence of malonic acid and succinic acid in partially dried Merbau wood samples. Both solvents desorbed different types of volatile compounds. The burning behaviour of partially dried Merbau wood were different to those documented from fully dried Merbau wood and is attributed to the composition of wood rather than the dry or wet conditions.
In Malaysia, dengue fever is a common vector-borne disease. Most cases of dengue fever are reported in residential areas. Children are at high risk to be infected because they spend a lot of time around their housing area for outdoor activities. Such areas may have a high number of Aedes mosquitoes. As schools are equipped with infrastructure and medium for effective educational purposes, schools represent the most suitable facilities for learning and teaching process. A crosssectional study was conducted to determine the level of knowledge among students in Hulu Langat on Aedes mosquitoes, dengue fever, and Zika virus. The study also reported on the demographic factors which affected the knowledge level. Based on sample size calculation using G*Power v3.1 software, a total of 171 respondents were needed from the two primary schools involved in the study. Data collection was conducted using a pre-tested questionnaire that consisted of two main sections on demography and knowledge about Aedes mosquitoes, dengue fever and Zika virus. From the total score of 55, the mean knowledge score is 34.2 ± 8.38. Based on the median value of 36.0, about 50.9% of respondents had satisfactory knowledge. From the study, it was found that students from School A, students who had been watching video related to Aedes mosquito, and those with history of dengue infection among family members had a significantly better knowledge score (p < 0.01). In conclusion, knowledge about Aedes mosquitoes and related illnesses need to be enhanced through a comprehensive module and effective educational materials that can serve as a reliable source of information for primary school students.
Microbiological contaminations in the laboratories create not only diagnostic issues but also pose a major health risk to lab users. This study was conducted to determine the airborne microbial contamination in seven selected laboratories (KA, KP, PB, NA, BP, CR and MB) at a local public university in Malaysia and to assess the level of contamination on the contact surfaces of the studied laboratories. Two types of sampling methods were used in this study; passive air sampling and contact surface swab sampling. The total microbial counts were determined using Tryptone Soya agar (bacterial count) and Potato Dextrose agar (fungal count). Results showed that NA laboratory had the highest level of total microbial contamination (20.33 ± 3.35 CFU/cm3). Most laboratories had significantly higher (p < 0.05) air fungal contamination level compared to bacterial contaminations except for PB and NA laboratories. Significant differences were observed for airborne bacterial contamination readings between sampling time (during working hours vs after hours) for all laboratories except for BP and CR. Overall, bacterial contamination was the highest for incubator door handles’ samples from MB laboratory with an average reading of 93.00 ± 1.43 CFU/cm2 whereas the highest fungal contamination level was obtained from door knobs and work benches, both from CR laboratory with an average reading of 73.33 ± 6.67 CFU/cm2 and 73.33 ± 0.58 CFU/cm2 respectively. Findings from this study could assist in monitoring the efficacy of the existing laboratory management systems namely on the good laboratory practices including aseptic techniques, care for laboratory hygiene and cross-contamination control practices by the laboratory users to ensure that the microbiological contaminations in the laboratories are minimized.
Certain public service pre-school teachers have been trained as vision screeners of children. However, there are no studies that assessed the knowledge and skills retention of these screeners. This study determines the level of knowledge retention among pre-school teachers who have been trained to perform vision screening on children. In 2013, 180 KEMAS pre-school teachers were recruited in a vision screening training which included both theory and practical sessions. Teachers were assessed through a theory test which comprised of 15 questions, firstly a category on the preparations needed for vision screening and secondly on the implementation of vision screening. They were then asked to conduct pre-school vision screening annually at their working premises. In 2016, 136 teachers who had been involved in the earlier program were recruited as subjects in this study. All these subjects answered the same set of theory test questions used in 2013. The Student’s t-test result indicated that the mean theory test scores obtained by the pre-school teachers in 2013 (84.3 ± 7.8) differed significantly with the mean scores obtained in 2016 (67.5 ± 11.3) (p < 0.001). The mean scores in 2013 for questions in the first and second categories were 4.5 and 4.4, decreasing to 4.2 and 3.7 in 2016. The knowledge level of pre-school teachers thus decreased with time and this effect was found significant after 3 years. There is therefore a need to conduct re-certification training, so that the screening conducted by these pre-school teachers remains effective and in accordance with established standards.
Fibres are important trace evidence that can be found during the course of crime scene investigation. The identification and analysis of these fibres shed light as to the circumstances surrounding a particular crime. Identifying the factors that affect the transference of fibres under various environments are crucial in providing robust conclusions of a case per se, as highlighted in this work. Donor garments were made up of four different types of fibre; 100% cotton, 100% nylon, 100% polyester and 100% wool, that were used to observe the differences in the number of transferred fibres to the recipient garment (100% cotton) and vice versa with increasing contact times of 30, 60, 180, and 300 seconds respectively. To simulate contact between the donor garment worn by a suspect and the recipient garment worn by a victim in real-life situations, the donor garment was placed on top of the recipient garment which was laid on a piece of plywood. The numbers of transferred fibres, both from the donor to the recipient garment and from the recipient to the donor garment were observed and tested using microscopic examination, burning test, solubility test and dye extractability test. Results indicated that different types of garments transferred different number of fibres with increasing contact times, and the identification of the fibres are possible via the different tests applied in this work.
Walking 10,000 steps daily is associated with beneficial health outcomes. Recent systematic reviews have suggested that pedometers may be an effective motivational tool to promote walking. The aim of this study was to study the effectiveness of a 10-week, pedometer-based walking intervention to improve physical activity, body composition and metabolic health indices in a sample of suburban community-dwelling adults not meeting current physical activity recommendations. After screening, 34 overweight/obese individuals (mean age: 46 ± 8 years, mean BMI: 28.3 ± 4.2 kg/m2) were accepted into the walking program conducted by the Health Promotion Community Centre, Bangi. Subjects were instructed to increase their steps by 3000 steps daily above their baseline values for 10 weeks. Daily step count, body weight, BMI, waist circumference, as well as blood pressure, fasting glucose and lipids were evaluated at baseline and following the 10-week intervention. Thirty-one participants completed the program with 100% adherence. The average daily steps recorded during the 10-week intervention was 9693 ± 2196 steps per day. Mean daily steps increased from 8679 ± 2567 steps in Week 1 to 10,766 ± 3200 steps in Week 10 (p = 0.040). Overall, there were reductions in body weight (-1.13%, p = 0.010), waist circumference (-3.5%, p = 0.001) and BMI (-1.41%, p = 0.008) as well as fasting blood glucose (-8.5%, p = 0.003) and systolic blood pressure (-4.8%, p = 0.007) following the intervention. The findings of this study demonstrated that a goal-driven, pedometer-based walking intervention for 10 weeks resulted in a modest reduction in body weight and improved metabolic health outcomes in overweight/obese, community-dwelling adults.
