  This study was conducted to evaluate the associations between Body Mass Index (BMI), body weight perception and weight control behaviors among the undergraduate students in UKM and to identify gender differences in BMI, body weight perception and weight control behaviors between males and female students. A total of 200 subjects of UKM students have participated in (50% males and 50% females). Subjects involved were in the range of 20 to 25 years old. Information about socio-demographic, body image perception, body shape, weight control behaviors were obtained by questionnaire. Anthropometric measurements of body weight and height were also taken. The mean for age, weight, height and BMI were 22.2±1.4 years, 69.1±13.4 kg, 1.7±0.1 m and 23.3±4.1 kg/m2 respectively for males while 22.5±1.4 years 56.8±14.8 kg, 1.5±0.1 m and 22.2±4.7 kg/m2 for females respectively. There were significant differences in weight, height and BMI between males and females (p<0.05). Based on BMI categories (WHO, 2004), the results showed that 16.5% of the total subjects were classified as underweight, 57.0% normal weight, 17.0% overweight and 9.5% obese. Results showed that the actual weight (BMI) of subjects was significantly related to the body weight perception in overall (p<0.05) and also for both sexes (p<0.05). There were also a significant differences between actual body weight (BMI) (p<0.05) and body weight perception (p<0.05) with weight control behaviors in overall and in both sexes. Understanding the reasons for gender differences in actual weight and body weight perception can help health professionals in helping people to make strategic decisions to control body weight.

  Nutrition knowledge is vital in determining the pattern of food intake of a particular individual in daily life. The main purpose of this study was to determine the dietary habits and nutrition knowledge among athletes and non-athletes in National University of Malaysia (UKM). This study was also aimed to determine the relationship between the body mass index (BMI), dietary habits and nutrition knowledge. The total number of respondents was 200 people with 100 athletes were selected from 7 types of sports and 100 non-athletes were selected at random from non-athletes in UKM. Anthropometric measurement included height and weight. Questionnaire was used to assess the socio demographic variables, nutrition knowledge and dietary habits. The results showed that the mean score of dietary habits for athletes (48.9±5:08) was significantly lower, compared to non-athletes (50.4±4.35) (p<0.05). The nutrition knowledge overall mean score was (83.6±6.5), corresponding to a good level of knowledge, while the athlete nutrition knowledge score (83.7±6.84) was not significantly different (p>0.05) than non-athletes (83.5±6:23). The main sources of nutrition information for athletes was from the internet (82%), newspapers or magazines (70%), families or friends or neighbours (65%), television (60%) and coaches (52%). This was quite similar to non-athletes but they did not choose coaches as a source of information. The BMI of athletes and non-athletes did not show a significant relationship with dietary habits and nutrition knowledge. However, it was found that there was a weak significant positive relationship between nutrition knowledge and dietary habits of athletes (r = 0.328, p<0.01) but had no significant relationship to non-athletes. In conclusion, non-athletes displayed healthier dietary habits than athletes but no significant difference in nutrition knowledge between both groups.

  This study was conducted to determine the associations between body mass index (BMI), body weight perception and body shape among male and female adolescents. Besides, the aim of this study was to identify the differences in weight control behaviours between male and female adolescents. This cross-sectional study involved 194 subjects (98 males and 96 females) who were randomly selected from two secondary schools in Pulau Pinang. Subjects involved, were in the range of 16 and 17 years old. Information on socio-demographic, body image perception, body shape and weight control behaviors were obtained through questionnaires. Anthropometric measurements of body weight and height were also taken. Based on BMI categories (WHO, 2007), the results showed that 12.9% of the study subjects were classified as underweight, 55.2% normal weight, 17.5% overweight and 14.4% obese. The study found that the actual weight (BMI) of subjects were significantly associated to the body weight perception in overall and also for both sexes (p<0.05). There was a significant association between the selection of the current body shape and ideal body shape for both sexes (p<0.05). BSQ scores also showed a significant association with actual weight (BMI) for both sexes (p<0.05). This study showed that there was a significant association between males and females (p<0.05) based only on 2 out of 12 items of healthy weight control behaviors used in food diet and increasing physical activity. While for the 3 out of 9 items of unhealthy weight control behaviors used in skipping meals, starting the use of tobaccos and fasting, the study showed that there was a significant association between the sexes (p<0.05). Therefore, by understanding the reasons for gender differences in the actual weight and weight perceptions, it could assist health professionals in helping a person to make a strategic decision to control body weight thus could help avoid the risk of eating disorders.

  The aim of this study was to determine knowledge, attitudes and practices on hydration and fluid replacement among endurance sports athletes in Universiti Kebangsaan Malaysia (UKM). This study was also to identify the relationship among these parameters. A total of 80 UKM endurance sports athletes were involved in this study. Data collection was conducted using anthropometric measurements and questionaires. Anthropometric measurements included height, weight and body composition using bioimpedance method. Socio-demographic information, hydration knowledge, attitudes and practices were collected using questionnaires. The mean age of athletes was 22.0±2.6 years. The mean score for knowledge, attitudes and practices of subjects towards hydration was 74.1±10.1, 60.9±20.3 and 76.1±14.6%, respectively with higher scores indicating positive hydration knowledge, attitudes and practices. Knowledge did not show a significant correlation with practices (r = 0.126, p>0.05) but significant correlation with attitudes (r = 0.285, p<0.05). However, attitudes showed a positive significant correlation with practices (r = 0.421, p<0.01). Most athletes correctly answered the general hydration questions on the survey but under the assumption regarding usage of salt tables to avoid hydration and thirst is the best indication for dehydration. They are also lacked knowledge regarding appropriate use of sports drinks. The mean score of knowledge, attitudes and practices for subjects with previous nutrition education was not significantly different compared to subjects without nutrition education (p>0.05). Only the mean score of knowledge was significantly different between male and female (p<0.05). Improvement of hydration knowledge, attitudes and practices is the most relevant step to ensure the hydration level of athletes is at its optimum level during training and competition. The results of this study identify specific areas of education for athletes with regard to hydration.

  Aboriginal children are known as one of the communities that engaged the highest prevalence of malnutrition in Malaysia for ages. The study was participated by 256 (131 males and 125 females) aboriginal preschooler aged one to six years from Gua Musang, Kelantan. This study attempts to determine the current prevalence of malnutrition and to identify the possible factors that may be associated with malnutrition among the subjects. This cross-sectional study was carried out between September to December 2014 at three aborigines’ settlements. Socio-demographic and economic status information, health history and anthropometric measurement of the participants were obtained and all the subjects were screened for presence of soil-transmitted helminths (STH). Current study revealed that the prevalence of underweight and stunted was 45.3 and 76.2%, respectively. From the analysis, there was no significant associated factors between demographic, socioeconomic, health history and personal hygiene with underweight (p>0.05). However, binary logistic regression confirmed that the significant factors contribute to stunting were household monthly income (<RM520) (p<0.01), number of siblings (>5) (p<0.01) and gender (male) (p<0.01). The current prevalence of malnutrition is still a major concern for public health with lower family monthly income and is the main factors that contribute to stunting. Hence, government should consider revising health strategies to overcome these issues in order to provide a better future for these children to survive.

  Background and Objective: The complexity of study routine and job nature of firefighters require them to be physically fit and to possess good cardiorespiratory capacity, muscle strength and resistance including a good body composition. This study aimed to identify the relationship between body composition and physical fitness of rescue firefighter personnel in Selangor, Malaysia. Materials and Methods: A total of 230 male firefighters aged 20-39 years from 9 randomly selected districts in Selangor participated in this study. Anthropometric measurements, including height, weight, body composition and waist circumference were taken. Individual proficiency performance test was performed using bent knee sit-up, standing broad jump, pull-up, 4×10 m shuttle run and 2.4 km run to assess physical fitness. The VO2 max test was also conducted to evaluate aerobic fitness. Results: This study revealed that 42.6% subjects had normal body weight, 46.5% were overweight and 10.3% were obese. The means of bent knee sit-up test, standing broad jump, pull-up test, 4×10 m shuttle run, 2.4 km run and VO2 max test were 41.52±7.18 count, 222.41±26.03 cm, 6.93±3.79 count, 10.29±0.86 sec, 13.16±2.84 min and 37.66±5.25 mL kg–1 min–1, respectively. Body fat was significantly correlated with bent knee sit-up test (r = -0.289, p<0.001), standing broad jump (r = -0.248, p<0.001), pull-up test (r = -0.450, p<0.001), 4×10 km shuttle run (r = 0.347, p<0.001) and 2.4 km run (r = 0.371, p<0.001). Body mass index exhibited a significant correlation with bent knee sit-up test (r = -0.272, p<0.001), standing broad jump (r = -0.234, p<0.001), pull-up test (r = -0.484, p<0.001), 4×10 km shuttle run (r = 0.430, p<0.001) and 2.4 km run (r = 0.399, p<0.001). Body weight also showed a significant correlation with knee sit-up test (r = -0.239, p<0.001), standing broad jump (r = -0.187, p<0.01), pull-up test (r = -0.491, p<0.001), 4×10 km shuttle run (r = 0.396, p<0.001) and 2.4 km run (r = 0.350, p<0.001). Conclusion: A specific training programme should be implemented to improve the body composition components and physical fitness among Malaysian firefighters. The body composition components, such as body fat, body mass index and body weight seem to influence physical fitness among Malaysian firefighters excluding aerobic fitness.

  Background and Objective: Various studies on nutritional status and nutrition knowledge have been widely reported but studies involving royal Malaysia police (RMP) are very limited. The purpose of the study was to evaluate physical characteristics and body composition of RMP personnel, to determine level of food pyramid knowledge and to identify relationship between socio-demographic and physical characteristics with food pyramid knowledge. Materials and Methods: A total of 286 male RMP personnel were randomly selected from a district police headquarter in Selangor. Anthropometric measurements involved height, weight, waist circumference (WC) and body mass index (BMI). Body fat and fat mass were measured using bioelectrical impedance analysis method. Questionnaire was used to assess the food pyramid knowledge. Results: This study showed that 33.6% subjects had normal BMI, 44.4% were overweight and 22.0% were obese. About 50.7% subjects had WC value of 90 cm or more and 78.3% subjects had high body fat. The mean food pyramid knowledge score was 56.8±11.9% corresponding to a moderate level of knowledge. Inverse correlation between food pyramid knowledge with age (r = -0.173, p<0.05) and duration of services (r = -0.160, p<0.05) was reported while positive correlation was observed between food pyramid knowledge and BMI (r = 0.124, p<0.05). Conclusion: Majority of the RMP personnel were having high BMI, high WC and high body fat percentage. Level of food pyramid knowledge was moderate among the RMP personnel. Nutritional education and fitness program should be incorporated in the RMP to optimize their health and knowledge.

  Objective: This study aimed to determine knowledge, attitude and practice levels regarding anaemia among pregnant women in Putrajaya. This study was also conducted to identify the associations between knowledge, attitude and practice and socio-demographic and antenatal characteristics. Methodology: A total of 370 pregnant women participated in this study. Socio-demographic information and antenatal characteristics and knowledge, attitude and practice in relation to anaemia were collected using questionnaires. The Sysmex Haematology Analyser was used to measure the Full Blood Count (FBC). Results: The mean age and haemoglobin level of respondents were 30.2±4.2 years of age and 12.1±4.8 g dL–1, respectively. The median for the total knowledge score was 84.2 and the mean score for attitude and practice were 72.4±6.7 and 69.9±13.1, respectively. The subjects’ knowledge score was higher among the group of second trimester (p<0.05), the number of children three or more (p<0.01) and a pregnancy distance of one to two years (p<0.001). The attitude score was higher among the working subjects (p<0.05) but there was no significant difference in practice scores according to sociodemographic and antenatal characteristics (p>0.05). Knowledge had a moderate and significant relationship with attitude (r = 0.317, p<0.01) but no significant relationship with practice. Meanwhile, attitude had a significant positive and moderate relationship with practice (r = 0.330, p<0.01). Conclusion: Positive attitude regarding anaemia influences the high level of knowledge and good practice concerning this condition. Increasing the level of awareness of anaemia among pregnant women is seen as an important step in improving knowledge, attitude and practice levels regarding anaemia.

  Background and Objective: This study aimed to compare the level of knowledge on type 2 diabetes between adults with and without diabetes in Universiti Kebangsaan Malaysia (UKM), Bangi. Materials and Methods: The sample of this study included 202 UKM staff members including 101 diabetic respondents (DRs) and 101 non-diabetic respondents (NDRs) aged between 30 and 59 years. A questionnaire was used in this study to collect information on the respondents’ sociodemographics and knowledge about type 2 diabetes. Results: The overall mean age for the respondents was 49.6±6.4 years. This study revealed that the mean score of knowledge for DRs and NDRs was comparable, with 80.4±14.0 and 76.7±14.3%, respectively (p>0.05), responding in the good category. The percentage of respondents for DRs that answered correctly on a few individual questions was significantly higher compared with NDRs (p<0.05), such as diabetes is a condition of insufficient insulin, complications include loss of sensation in the arms and legs, tablets and capsules are available for the control of diabetes and diabetics should carry sweets when they are out. The highest mean scores were obtained by DRs (95.0±14.6%) and NDRs (94.6±1.4%) in the monitoring sections (p>0.05), while the lowest scores were found for the general knowledge section, with a mean score of 69.1±23.0 and 65.7±20.0%, respectively (p>0.05). There was a significant difference in the mean score for the treatment and management of diabetes section between the DRs (80.5±18.8%) and NDRs (74.3±17.7%) (p<0.05). Conclusion: The level of knowledge on type 2 diabetes for both groups was good. The information gained could subsequently be helpful for the Health Center of the UKM and Health Ministry of Malaysia to design and initiate comprehensive programmes for the detection and control of diabetes and its complications with self-care and community support as its major components.

Background and Objective: The increase in obesity among male military veterans (MVs) is often associated with low levels of physical activity and unhealthy food intake. This situation causes various health diseases if actions are not undertaken to overcome this problem. Therefore, this study aimed to evaluate the level of physical activity and to determine the relationship between body mass index (BMI) and physical activity level among MVs in Marang, Terengganu, Malaysia. Materials and Methods: This study involved 209 male MVs aged 40-60 years old. Data collection involved anthropometric measurements, including weight, height and waist circumference (WC). Meanwhile, the instrument comprised questions regarding sociodemographic characteristics, health status and physical activity habits. The physical activity level (PAL) was measured using the International Physical Activity Questionnaire (IPAQ). Results: This study showed that 41.1% of the respondents were categorized as normal weight, 42.1% overweight and 16.8% obese. The mean weight, height, BMI and waist circumference were 75.213.5 kg, 169.76.3 cm, 26.14.2 kg m–2 and 83.99.7 cm, respectively. A total of 20% of respondents showed a WC of more than 90 cm and were considered to be at high risk of cardiovascular disease and diabetes. Most of the subjects preferred sedentary behaviour, such as watching television/listening to the radio (52.6%), to exercise (7.2%). The average PAL of the respondents was 2445.8±642.1, with most of the respondents reporting a moderate PAL (81.3%) compared to a high (15.8%) or low PAL (2.9%). There was a negative correlation (p<0.01) between BMI and low, medium and high MET physical activity scores r = 0.210, p = 0.002; r = 0.638, p<0.001; r = 0.423, p<0.001, respectively). Conclusion: Most of the MVs in this study had moderate PALs. The Veterans Association of Malaysia Armed Forces can use the information collected to plan health-related programmes to prevent unhealthy lifestyles and chronic diseases among MVs.

Background and Objective: Studies on the relationship between stress, physical activity levels and body mass index (BMI) among secondary school students are limited in Malaysia and information describing each factoris scarce. This study was conducted to determine the stress and physical activity levels among adolescent secondary school students in the state of Penang and to identify the relationship between stress, physical activity levels and BMI. Materials and Methods: A total of 420 adolescents from four different schools in Penang were randomly selected as subjects for this study. Data collection was carried out through anthropometric measurements, the depression, anxiety and stress scale (DASS-21) and the international physical activity level questionnaires (IPAQ). The anthropometric measurements included weight and height. Results: DASS-21 results showed that the subjects experienced a normal depression level (8.50±6.78), a moderate anxiety level (10.0±6.96) and a normal stress level (11.95±7.00). The condition with the highest prevalence among the subjects was anxiety (60.0%) followed by depression (40.0%) and stress (29.5%). The level of physical activity among the subjects was high with mean of metabolic equivalent (MET) scores of 4207.6±3606.4 for total physical activity. The DASS-21 showed a significant but weak negative correlation between depression scores and MET scores for male subjects (r = −0.154, p<0.05) and overall subjects (r = −0.145, p<0.01). There was no correlation between BMI and all DASS components but a negative correlation with BMI was observed for high intensity physical activity (r = 0.214, p<0.01) and total MET scores (r = -0.174, p<0.05) for male subjects. Conclusion: The depression and stress levels were found to be at normal levels whereas the level of anxiety was found to be moderate. The level of physical activity was high. A significant negative correlation of depression with DASS and MET scores was observed for male and overall subjects.

Background and Objective: Internet use among university students has increased dramatically in recent years leading to internet addiction for some students. The study was conducted to determine the internet addiction, the risk of eating disorders among students in UKM and to identify the relationship between internet addiction, risk of eating disorders and body mass index. Materials and Methods: A total of 351 undergraduate students between 19 and 27 years old were selected using a convenience sampling method. The data collection process was done through anthropometric measurement and questionnaire. Anthropometric measurement was performed to determine the body mass index (BMI) which is determined by body weight and height. The questionnaires included socio-demographic information and health status. Internet addiction was assessed using the Internet Addiction Test (IAT) while eating disorder was assessed using the EAT-26. Results: The results showed that IAT mean scores for male (39.6±10.0) and female (38.3±10.2) subjects did not differ significantly (p>0.05). Most subjects had mild levels of internet addiction (66.7%), while some had a moderate (13.4%) level and the rest had no internet addiction (19.9%). The risk of eating disorders was 16.5% (male: 18.9%, female: 14.2%). The IAT scores was significant and positively correlated with the EAT-26 scores (r = 0.120, p<0.05) for female and all subjects. In addition, there was a significant positive correlation between IAT scores and BMI for males (r = 0.218, p<0.01) and all subjects (r = 0.157, p<0.01) and between EAT-26 scores and BMI for male subjects (r = 0.260, p<0.01) and all subjects (r = 0.207, p<0.01). Conclusion: The internet addiction levels were found to be at mild levels. A significant positive correlation between IAT and EAT-26 scores for female and all subjects and between IAT scores and BMI was observed for male and all subjects.
