Introduction: Obesity has been recognized as a major public health concern due to lack of physical activity and a sedentary lifestyle. Methods: This cross sectional study was carried out to determine the status of body mass index (BMI) and habitual physical activity level among staffs working in Military Hospital, Malacca using Habitual Physical Activity Questionnaire (HPAQ). Results: About 120 HPAQ were distributed and only 82 responded with 23(28%) of them males and 59 (72%) females, aged between 21 to 59 (40.52 ± 9.38) years old. Anthropometry analysis showed the mean weight of male respondents was 79.48 (± 16.33) and 70.95 (± 15.66) for the females. Body mass index (BMI) for males (33.61 ± 2.82) was almost similar to females ( 33.20± 2.95).The mean waist circumference of men was 93.26 (± 10.94)cm compared to 94.03 (± 11.98)cm in the females. Following categorization of BMI, 59% (n=48) are in the obese group, 24% (n=20) are overweight and only 17% (n=14) have an ideal body weight or normal BMI. Relationship between BMI and HPAQ demonstrated strong and significant correlation coefficient for habitual physical activity at work (r = 0.775, p < 0.001), sports (r = 0.735, p < 0.05) and leisure ( r = 0.713, p < 0.001). Conclusion: The staffs working in the Hospital demonstrated poor habitual physical activity which explains for the high incidence of obesity among the staffs. This requires measures to be taken to promote a healthier lifestyle among them.
Objective: To assess psychiatric morbidity, personality profiles and saliva cortisol levels in overweight and obese individuals at dietician clinic. Method: This cross-sectional study is based on individuals who attended dietician clinic between June to November 2008. They had completed questionnaires that included General Health Questionnaire 30-items, assessment for psychiatric illness using Structured Clinical Interview for DSM-IV and personality profiles using Personality Assessment Schedule. Saliva and body mass index were taken. Results: Of the 102 patients, 16 (15.7%) were diagnosed to have psychiatric illness. There were no differences between obese and overweight patients in terms of personality traits and psychological problem. Presence of psychiatric illness was associated with higher mean body mass index. Saliva cortisol levels were not elevated in patients who had psychiatric illness. Conclusions: Psychiatric illnesses are common in individuals who seek weight treatment. Careful psychological evaluation is important at (or before) commencement of a diet program.
Leptin, a 167 amino-acid product of the ob or LEP gene, was first reported in 1994 after a 40-year search that began following the emergence of a mutant strain of mice with hyperphagia, early on-set obesity, and delayed sexual maturation. Since then, leptin deficiency has also been reported in the rat, and more recently in humans. It is secreted constitutively primarily by the white adipose tissue, and in smaller quantities by a number of non-adipose tissues. It acts by binding to specific membrane bound leptin receptors, belonging to the class 1 cytokine receptor family, and activating the JAK-STAT system. Leptin regulates appetite and body weight mainly through its actions on the hypothalamus involving the NPYmelanocortin pathway, and, to a lesser extent, through increased energy expenditure by way of sympathoactivation and increased substrate cycling. Its effects on reproduction, puberty in particular, are mediated through actions on the hypothalamic-pituitary-gonadal axis and on the gonads. Leptin also appears to have permissive roles in CNS development during the neonatal period, bone growth and development, and in haemopoietic and immune functions. Although it was its deficiency state that first led to its discovery, it now appears that the clinical significance of leptin lies not only in the consequences of its deficiency but also when it is in excess as occurs in obesity. Emerging evidence is implicating leptin as a link between obesity associated cardiovascular disease risks and infertility. Besides this, leptin is also being implicated as a growth factor in cancer. The story that started with a search for a body weight regulating factor is now unfolding into one that is revealing roles for leptin that stretch beyond the regulation of appetite and body weight.
Night work and rotating shift work are found to be detrimental to the health of workers. A cross sectional analytical study was conducted among the employees of a public medical centre in Kuala Lumpur. A total of 380 employees participated in the health screening and questionnaire survey. The majority of the respondents were Malays, females, and with mean age of 49 years old. The shift workers persistently had higher but non-significant proportions of being overweight/obesity and unhealthy clinical indicators such as systolic and diastolic blood pressure, fasting blood glucose and lipid profile except waist circumferences and HDL-cholesterol. There were also slightly more shift workers diagnosed with diabetes mellitus, hypertension or coronary heart disease (p>0.05). Although the present study could not provide established evidence for a relationship between shift work and cardiovascular risks, this could serve as a pilot study for future studies in this area.
Non-communicable diseases are raising much concern in Malaysia due to changing lifestyles which is parallel to the economic development. Intervention program like community health screening (CHS) allows early detection, prevention and reduction of chronic diseases and its risk factors. This study aimed to assess the obesity level, risk factors for chronic diseases and blood cholesterol level among the Malaysian public. A health screening program was conducted on April 2012 at Sungai Pinang township, in the state of Pulau Pinang, Malaysia. A convenient sample of the general public was recruited. Screening tests consisted of measurements of blood pressure, body mass index (BMI), body fat percentage, visceral fat accumulation (VFA) and blood cholesterol. Chi-square analysis was used to determine the difference between prevalence of obesity among subjects with different age groups and gender. Out of 76 recruited subjects, 23.7% had systolic blood pressure of 140 mmHg or greater and 7.9% had diastolic blood pressure of 90 mmHg or greater. Approximately 51% of the subjects were obese (BMI ≥ 27.5 kg/m2). Body fat percentage was high in 63.6% and 63.0% of male and female subjects, respectively. High VFA (≥15) was found in 19.8% of subjects. There were three newly discovered hypercholesterolemia cases (total cholesterol ≥ 5.2 mmol/L). Counselling was given during the health screening program to help the public to take necessary measures to reduce risk factors while preventing complication resulting from these chronic diseases. In conclusion, prevalence of obesity found to be high in the present screened population.
Poor appetite and inadequate food intake together with depression are associated with malnutrition, that will increase risk of morbidity and mortality among elderly people. Identifying factors associated with these conditions are essential for formulation of preventive strategies. Therefore, a study was conducted to identify factors associated with poor appetite and depression among institutionalised Chinese elderly people in Butterworth, Penang. A total of 100 Chinese elderly (49 men and 51 women) aged 60 years and above, (mean age ± SD of 74.7 ± 9.2 years), with no known terminal and mental illnesses from two nursing homes participated in this study. Subjects were interviewed to gather information on appetite using Council of Nutrition Appetite Questionnaire (CNAQ), depression using Geriatric Depression Scale (GDS) and also socio demographic and health status. Food intake was assessed using a combination of one-day food weighing and 24 hour diet recall. Body weight and height were measured. Results showed that the mean energy and nutrients intake did not achieve the Recommended Nutrient Intake of Malaysia (RNI), with the exception for vitamin C. Only 4% of the subjects were underweight and obese, 65% normal and 31% overweight. A total of 70% and 73% of subjects had poor appetite and depression, respectively. Subjects who had depression (adjusted OR = 2.78, 95% CI = 0.95-8.03), energy intake below RNI (adjusted OR = 2.34, 95% CI = 0.68-6.95) and difficulty to fall asleep at night (insomnia) (adjusted OR = 2.22, 95% CI = 0.72-6.82) were more likely to have poor appetite. Subjects who had poor appetite (adjusted OR = 3.36, 95% CI = 1.19-9.47) and insomnia (adjusted OR = 2.58, 95% CI = 0.83-7.98) were more likely to have depression. In conclusion, although the majority of subjects had normal body weight but the nutrient intake was inadequate. Poor appetite and depression were prevalent and interrelated and also strongly associated with insomnia.

Objective: This study aimed to determine the prevalence of obesity among patients with schizophrenia and its association with the demographic profile. Methods: This is a cross sectional study. Subjects were selected using systematic sampling. Patients attending the out patient psychiatric clinic, Hospital Universiti Kebangsaan Malaysia, who fulfilled the criteria and able to give consent were included in this study. Diagnosis of schizophrenia was made using Structured Clinical Interview (SCID) for DSM-IV. Demographic profiles of the patients were obtained and anthropometric measurements were measured and classified according to Body Mass Index (BMI) and Waist Circumference (WC) of Asian population. Results: A total of 97 patients were included. The prevalence of overweight (BMI: 23.0- 27.4 kg/m2) was 39.2% (n=38), and the prevalence of obesity (BMI: >27.0 kg/m2) was 35.1% (n=34). BMI was higher among non-Chinese (Malay and Indian, p=.03) and those who had low total household income (p=.03). Sixty-two patients (63.9%) had high WC, which was associated with male (p=.003) and non-Chinese (p=.03). Conclusions: Obesity is highly prevalent among patients with schizophrenia. The risk factors for obesity include male, non-Chinese and those with low total income. The high WC among non-Chinese and male patients suggests that they are at a higher risk of developing obesity-related physical illnesses. These findings support that obesity is a common critical issue among schizophrenic patients, and it warrants serious clinical interventions.

Food is closely related with emotion. It often provides comfort and satisfaction. Some individuals choose to turn to food to curb their negative emotion, resulting in disturbances in
eating patterns, such as overeating which lead to obesity and severely controlling food intake, which culminate in eating disorders like anorexia nervosa, bulimia nervosa and binge eating. These disorders are not related to the eating problems per se but often due to underlying or complicated by psychological factors, namely depression, anxiety, impulse control problems and personality. The roles of psychological factors in eating disorders and obesity should therefore not be downplayed. These disorders should be managed comprehensively involving multiple approaches, including not only biological but also psychological interventions provided by a professional team comprising endocrinologists, psychiatrists, dietitians, exercise physicians and surgeons.
Various studies have reported that excess body weight may increase the risk to various diseases and death. A study reported that adolescents who were overweight were almost 18 times more likely than their leaner peers to be obese in early adulthood and were 8.5 times more likely to have hypertension as young adults. Therefore, this study was conducted to determine the body composition and four dietary factors i.e., prudent diet habits, calorie control habits, dietary fat/ cholesterol and sodium/salt control which may affect blood pressure and the risk of heart disease among year 1 medical students in a public university in Selangor. Body composition was determined by measuring the body mass index (BMI) and body fat percentage. None of the female students showed excellent/good eating habits while majority were fair (37.7%) and poor/very poor (62.3%). Nearly half of the male students showed excellent/good eating habits (42.5%), but more than half (57.5%) were poor/very poor. Majority of the female (85.7%, 85.7% and 94.8% respectively) and male students (80.9%, 57.5% and 93.6% respectively) showed excellent/good eating habits in calorie, dietary fat and salt control. Majority of the students (64.9% female and 61.7% male) have normal BMI values while 24.7% of female and 10.6% of male students were underweight (BMI values less than 18.5). Only a small number of female students were overweight (5.2%) and obese (5.2%). However 14.9% of male students were overweight and another 12.8% were obese.
Objectives: This study was carried out to determine the nutritional status of primary
school children aged 6 to 11 years in Sepang District and to compare the results with a
similar study carried out in 1999. Methods: This cross-sectional study was carried out in
Sepang District using stratified random cluster sampling technique. A pre-tested, structured
questionnaire was used to collect the data. Weight was recorded using a digital bathroom
scale TANITA model HD-309 and height was measured by using a SECA Body meter
Model 208. Body mass index (BMI) was calculated as weight in kilograms divided by the
square of height in meters. Classifications of the nutritional status of respondents was
based on WHO classification 1983 and 1995. Data were analysed using SPSS. Results:
The overall mean BMI for the 1,910 respondents was 16.8 (95% CI= 16.67 - 16.99;
SE=0.08). The median BMI was 15 .7 ranging from 9.51 to 36.75 kg/m2. The majority
(84.4%) had normal weight-for-age status, 7.6% respondents had weight-for-age status
below -2 SD of the NCHS-WHO median and 8.0% had weight-for-age status above +2 SD
of the NCHS-WHO median. The prevalence of underweight and overweight was significantly
higher in the males compared to the females (p< 0.05). There was a significant association
between underweight and ethnicity (p< 0.05). The majority (90.3%) had normal heightfor-
age status, 8.8% had height-for-age below - 2 SD of the NCHS-WHO standard median
and 0.9% had height-for-age above 2 SD from the NCHS median. The prevalence of
stunting was significantly higher in the male (10.3%) as compared to 7.4% in the females
(X2 = 5.11, P = 0.02). The majority (81.4%) of the respondents were within the normal
weight-for-height, 3.4% were wasted (weight-for-height was below - 2 SD of the NCHSWHO
median) and 15.2% of the respondents were obese (weight-for-height that is more
than +2 SD of the NCHS-WHO median). The prevalence of wasting was higher in the
females (4.1 %) compared to males (2.8%). The prevalence of obesity was slightly higher
in the males (15.4%) compared to females (14.9%). Conclusion: The overall nutritional
status of primary schools children is good. However, there still exists pockets of population
in Sepang where chronic and acute forms of undernutrition persist in these children.
Objective: The objectives of this study were to asses body mass index, fasting blood sugar , serum cholesterol levels and prevalence of Diabetes Mellitus among outpatients attending the Clozapine clinic at University Malaya Medical Center. Method: 36 patients had their height and weight taken at the start of the study. Their BMI (body mass index) was calculated. Fasting blood sugar, (FBS) and Fasting Serum Lipid (FSL) were performed. Result: The mean body mass index was 24.63. The prevalence of obesity was 13.89%. The prevalence of overweight was 27.8 % and the prevalence of underweight was 5.55%. The prevalence of Diabetes Mellitus was 2.78 %. Serum triglyceride levels appear to be elevated in those receiving Clozapine.Conclusion: It appears that Clozapine may predispose one to obesity. From our study we cannot conclude if Clozapine causes Diabetes Mellitus. However treatment with Clozapine may be associated with elevated levels of serum triglycerides.

The population with normal body mass index (BMI) but with abdominal obesity are most of the time the ‘neglected’ population in terms of health interventions. The aim of this study is to study the prevalence of abdominal obesity and to explore the factors causing abdominal obesity by using waist circumference (WC) measurement. A cross sectional study was conducted among a group of respondents in Tanjung Karang, Selangor, Malaysia from January until June 2010, among those aged 18 years old and above, to explore the demographic (gender and ethnics), lifestyle factors (physical activity, carbohydrate intake and smoking status) and measurement of body weight, height and waist circumference. A total of 629 subjects with normal BMI were studied. The prevalence of abdominal obesity was 36.1% based on WC (40.0% males and 70.0% females). The predictor model revealed that being non-Malay (aOR = 2.1; 95% CI: 1.35-3.20) and being female (aOR = 3.6; 95% CI: 2.51-5.06) were the associated factors of having abdominal obesity in normal BMI population. In conclusion, females and non-Malay were factors that were found to be associated with abdominal obesity in normal BMI population. This is important in targeting this vulnerable population with risk factors that can develop non communicable diseases for early interventions.
Dietary pattern analysis has emerged as important instruments to identify modifiable dietary risk factors for non-communicable diseases. The aim of this study was to determine the major dietary patterns among adolescents in Petaling District, Selangor and their associations with socio-demographic characteristics and obesity. An analytic cross- sectional study design was conducted in selected secondary schools in Petaling District. Sampling with probability proportionate to size was used and five schools were selected. Self-administered semi-quantitative food frequency questionnaire was used for data collection. Weight was measured with a digital bathroom scale (TANITA model) and height was measured using SECA body meter. Principal component factor analysis using varimax orthogonal transformation was used to identify the dietary patterns. Chi square was used to test for associations of dietary patterns with socio-demographic characteristics and obesity. Three major dietary patterns were identified: firstly, fruits and vegetables; secondly, sugar and fatand finally, meat and chicken which explained for 12.7%, 11.6% and 10.7% variation in food intake, respectively. There were significant associations between ethnicity, religion, family income, educational level of parents and the dietary patterns. However, there was no significant association between obesity and the dietary patterns. It may be more effective to describe a healthy diet using results of dietary pattern analysis in public health intervention, rather than describing single food items or nutrients. It is recommended that nutrition education programmes should be implemented in schools so as to prevent the development of obesity in the non-obese.
Obesity is a well-established risk factor for cardiovascular disease. The objective of
the study was to determine the prevalence of obesity and factors associated among secondary school students aged between 13 to 17 years at Slemani City Centre, Iraq. Methodology: A cross sectional study design was used. The calculated sample size was 1656. Probability proportional to size sampling technique was used to select the sample. A validated pretested questionnaire was used to collect the data. Weight and height were also taken. Data were analyzed using SPSS version 21. Chi-square test was used to determine an association between two categorical variables. Independent t-test was used to compare two means. Multiple logistic regression was used to determine the predictors for obesity. Results: The response rate was 92.54% and the overall mean age of the 1588 respondents was 15.42 (95% CI = 15.35, 15.49) years. The prevalence of overweight and obesity was 20.6% and 11.3% respectively. Variables significantly associated with overweight and obesity (age, monthly family income, education level of parents, body part satisfaction and body size perception) were entered into the logistic regression model. Multiple logistic regression analysis showed that the predictors for overweight and obesity were age, monthly family income, body part dissatisfaction and body size perception. Conclusion: The prevalence of overweight and obesity is high (20.6% and 11.3% respectively). The predictors of obesity among secondary school students aged between 13 to 17 years old at Slemani City Centre Kurdistan Region, Iraq were age, family income and body image dissatisfaction.
Objective: This study is an attempt to produce an abbreviated Malay version of Weight and Lifestyle Inventory (MWALI), as well as to examine the psychometric properties of the eating behavior which formed part of MWALI. Methods: The MWALI was translated ‘forward–backward’ from English to Malay and then administered to 135 adolescents. The factor construct of the 24-item eating behavior and the relationships between factor scores and demographic profile, dysphoria, global self-esteem and body mass index (BMI) were examined. Results: The exploratory factor analysis yielded five factors: Negative Emotion, Poor Impulse Control, Social Cues, Snacking and Early Meals in relation to over-eating. All the factors were significantly and positively correlated with BMI. Internal consistency and test-retest reliability of the eating behavior were satisfactory. Conclusion: MWALI is appropriate for assessing eating behavior among overweight and obese adolescents in the primary care setting in Malaysia.
The traditional physical and cosmetic-centered model without paying serious attention on the underlying psychosocial issues of care are ill suited to successful treatment outcome of obesity. The objective of this article is to report a case of a retired Malay army sergeant who presented with night eating syndrome (NES) with morbid obesity and dysthymia, and to discuss the psychobiological aspect of the case including to evaluate the effectiveness of the combination treatment of pharmacotherapy and cognitive behavior therapy along with diet counseling. The diagnosis was made by using the Structured Clinical Interview Diagnosis (SCID) for DSM-III-R diagnosis and the severity of depression was assessed by Hamilton Depressive Rating Scale. The patient’s body mass index was 45, He was found to have dysthymia and the Hamilton Depressive Rating Scale score was 13. We found that the combination of pharmacotherapy, cognitive behavior therapy and nutritional education with the help of the physician proved to be effective in treating morbid obesity with NES and Dysthymia.
Adequate nutrition is important for mothers and their offspring during and after birth. This cross sectional study was conducted to determine nutritional status and nutritional knowledge of pregnant women from two selected private hospitals in Klang Valley, Malaysia. A total of 236 Malay pregnant women aged between 20 to 45 years old (mean age 31+5 years) were recruited through convenient sampling method. Socio-demographic data, nutritional knowledge and a 24-hours diet recall were obtained through a self-administered questionnaire. Anthropometric and haemoglobin data were obtained from the antenatal records in the respective hospitals. The percentages of participants who were underweight, normal, overweight and obese before pregnancy were 12.7%, 55.1%, 25.0% and 7.2% respectively. Among those who were obese before pregnancy, a total of 59.7% had inadequate weight gain, 24.6% gained adequate weight and 15.7% gained excessive gestational weight. About 33.5% of subjects were anaemic (Hb < 11.0g/dL). The mean daily energy intake of the participants was 1748 ± 526 kcal which was 76% of RNI. Calcium (73% of RNI), folic acid (36% of RNI), niacin (89% of RNI) and vitamin D (40% of RNI). The nutritional knowledge level of subjects was moderate (51.9 ± 13.8%). Lower monthly household income (p < 0.001), educational level (p < 0.001) and gestational stage (p < 0.05) of participants were associated with a lower nutritional knowledge level. Nutritional knowledge score was positively correlated with gestational weight gain (r = 0.166, p < 0.05) and haemoglobin level (r = 0.200, p < 0.05). Subjects who claimed practising food taboos had higher nutritional knowledge score (54.9 ± 12.5%) than those who did not (49.9 ± 14.4%)(p < 0.05). A comprehensive nutrition education should be integrated in the antenatal classes to improve nutritional status of pregnant women.
Obesity continues to be one of the most important emerging public health problems over the past few decades in all developing countries, and recently in non developing countries also, because of improving living standerds. Lack of physical activity and leisurely attitude are one of the factors which determine the obesity and many factors influence the physical activity levels. The Leisure Time Physical Activities (LTPA) could be an important factor which decides energy balance, which can be influenced by self-perception of obesity. In this pilot study the impact of self-perception of obesity on LTPA (Kcal/week) using Compendium of Physical activities by Ainsworth et al was studied among medical students. The increased level of physical activity (LTPA) was observed among both genders with BMI less than 25; but female with overweight/obesity (BMI ≥ 25) showed significant correlation of LTPA with their BMI (r2 = 33.15%; p = 0.03). The subjects perceived their weight in proportion to their BMI especially male students. The subjects were grouped based on their self-perception of obesity, and significant correlation between self-perception of obesity and LTPA was observed among females who neither disagree, nor agree their obesity (group 3: r2 = 74.31%; p = 0.0003). Among males BMI was significantly different between the groups. Most of the male subjects perceived their overweight/obesity and more LTPA among those perceived not obese. Among females who perceived their overweight performed more LTPA to reduce their BMI. But in both gender those with BMI more than 25 and those strongly agree their obesity had less LTPA. Hence this study contends the impact of self-perception of obesity on LTPA among medical students and the importance of motivation for those who require intervening by improving their physical activities.
The objective of this study was to describe the differences in physical activity with socio-demographic factors and its association with cardiovascular risk factors. It was a cross-sectional study among selected urban and rural Malays communities in Kuching and Samarahan. Physical activity data was obtained using International Physical Activity Questionnaire (IPAQ) short version. Assessment of cardiovascular risk factors was based on blood pressure, fasting cholesterol and glucose and body mass index (BMI). Data was analysed using SPSS version 20. A total of 223 participated with higher response from rural areas (60.1%) and females (61.9%). More than half of the respondents (58.5%) were overweight and obese, with a mean BMI of 25.9 kg/m2 (SD=4.9). About 25% of the respondents were found to have blood pressure in the at-risk range. The prevalence of at-risk blood glucose was 52.3% with a mean value of 7.3mmol/L (SD=3.46). The prevalence of at-risk cholesterol were lower with 31.8%, mean value of 3.5 mmol/L (SD=2.94). There were more active respondents living in rural area (p=0.02). Logistics regression analysis showed that urban area (OR=1.988 95% CI 1.082 to 3.652), systolic blood pressure (OR1.020 95% CI 1.003 to 1.037) and blood cholesterol (OR0.884 95% CI 0.785 to 0.996) were associated with physical activity level. Change of physical activity due to urbanization can increase the risk of obesity and other chronic diseases. Efforts to include physical activity in intervention programme should be more intensified, with more provision of suitable built environment.
Obesity is a well-established risk factor for coronary heart disease, ischemic stroke, type 2 diabetes, cancers of the breast, colon, prostate and other organs. Objectives: To determine the prevalence of obesity and associated factors among university staffs. Methods: A cross sectional study was carried out among university staffs of University Putra Malaysia using a self-administered validated pre-tested questionnaire. Weight was measured using a digital bathroom scale (TANITA Model HD 319) and height was measured using a SECA Body Meter Model 206. Body mass index (BMI) was calculated as weight in kilograms divided by the square of height in meters (kg/m2). A p value of
