ABSTRACT

BACKGROUND: Physical inactivity is a significant public health issue affecting working adults because it can increase the risk of noncommunicable diseases. OBJECTIVES: The objective is to determine the outcomes of a multi-component workplace environmental intervention that incorporated physical activity self-regulation (PASR) to promote physical activity (PA) among employees. MATERIALS AND METHODS: This was a 6-month intervention with a two-group, parallel, quasi-experimental study. A total of 11 workplaces were randomly assigned to intervention group (IG) or control group (CG) using a 1:1 allocation ratio. In each group, 84 eligible participants were recruited. The IG was exposed to the organizational support and the PA support components throughout the study. The PASR Scale, International PA Questionnaire, and pedometer were used to measure the outcome at the baseline, 3rd-month, and 6th-month follow-ups, respectively. The repeated measures-analysis of variance analysis was used to determine the changes in the PASR skills, MET-min/week, and step/week over time. RESULTS: The IG had 75 participants (51 females and 24 males) and the CG had 73 participants (52 females and 21 males) at the 6th-month follow-up. Despite there was no statistically significant difference in the outcomes between groups over time, the IG showed significant improvements in total PASR (ηp2 = 0.021), goal setting (ηp2 = 0.024), total MET-min/week (ηp2 = 0.031), housework-related PA (ηp2 = 0.101), and step/week (ηp2 = 0.827) throughout this intervention. CONCLUSION: This intervention was found to be effective in improving the PASR skills, MET-min/week, and step/week of IG participants. Meanwhile, because some effect sizes were small, these findings should be interpreted with caution.

ABSTRACT

The coronavirus disease (COVID-19) pandemic has affected the well-being of individuals worldwide. Due to the scarcity of information in the Malaysian context, this study aimed at investigating the changes in well-being before and during the Movement Control Order (MCO) in Malaysia and its association with mental health status. This cross-sectional study was part of a Malaysian non-probabilistic online survey on psychosocial well-being in Malaysia, under the Personal and Family Coping with COVID-19 Global South Research Consortium. A total of 543 respondents (≥18 years old) were recruited using snowball sampling. A validated self-administered questionnaire for assessing sociodemographic characteristics, well-being, anxiety, boredom, and loneliness was circulated on social media platforms (such as Facebook, Twitter, and WhatsApp) and emails. Paired samples t-test, chi-square test, and multinomial logistic regression analyses were applied during data analysis. Results revealed significant changes in the mean scores of well-being, anxiety, boredom, and loneliness before and during MCO (p < 0.05). When comparing with no change in the well-being group, changes in boredom were less likely to be observed in the decreased well-being group (Adj OR = 0.874; p = 0.003) but were more likely to be observed in the group with increased well-being (Adj OR = 1.110; p = 0.002). The findings indicated that the pandemic did not necessarily create adverse effects. Instead, a different perspective is offered, which can be used as a public health strategy to help individuals cope with their mental health needs more positively.

ABSTRACT

Background: Postpartum depression (PD) among women, if left untreated, may result in long-term health and social consequences for them and their families. This cross-sectional study aimed to determine the factors contributing to PD among working mothers in Kuching, Sarawak, Malaysia. Methods: Systematic sampling was used to recruit working mothers who attended Kuching's maternal and child health clinics. They were interviewed with a validated translated questionnaire to obtain data on sociodemographics, health profiles, and Edinburgh Postnatal Depression Scale (EPDS) and postpartum symptoms. Data were analysed using IBM SPSS version 21.0. Results: Out of the total 281 respondents, 15.3% of respondents had depression symptoms. Fatigue (42.7%), back or neck pain (36.3%), breast discomfort (16.4%), dizziness (13.5%) and nipple irritation (11.0%) were the most common physical symptoms experienced by the mothers. Regression analysis showed that working mothers who exhibited higher scores of physical symptoms were 1.26 times more likely to develop PD (adjusted odd ratio 1.26, P < 0.01; 95% CI: 1.071, 1.487). Conclusion: Physical symptoms were the predictors of PD among working mothers.

ABSTRACT

Background: Academic stress is part of a student's life. Chronic stress may result in mental health problems, affecting the adolescent's well-being in adulthood. However, not all types of stress result in a negative effect. Therefore, understanding how adolescents adapt to academic stress can lay the groundwork for preventive interventions. The Response to Stress Questionnaire (RSQ) for academic problems centred on a multidimensional model of responses to stress. However, it has not been tested among Malaysians. Thus, this study aimed to validate the questionnaire among Malaysians. Methods: The questionnaire was translated into the Malay language using forward and backward translation. Data were collected via self-administered questionnaires at a secondary school in Kuching. A validity test was conducted using face and content validation by subject matter experts, and construct validation was performed using exploratory factor analysis (EFA). A reliability test was conducted by checking Cronbach's alpha. Results: Results showed that the questionnaire has good validity and reliability. The EFA resulted in only three dimensions of responses to stress among Malaysian adolescents in contrast to the five dimensions in the original RSQ for academic problems. The Cronbach's alpha showed good reliability of the questionnaire. Conclusion: The questionnaire measuring responses to stress was valid and reliable in assessing the responses of adolescents to academic stress.

ABSTRACT

Background: Disordered eating is common among late adolescents and young adults who pursue an idealised body image. Aims: This study aims to determine the prevalence of disordered eating between males and females and its associated factors among college and university students in Sarawak. Methods: A cross-sectional study involving 20 public and private colleges and universities in Sarawak, from September 2017 to March 2020. Respondents completed self-administered questionnaires both in the English and Malay language. Data about sociodemographic characteristics, body mass index, eating attitude, body dissatisfaction, perceived sociocultural pressure, self-esteem, drive for muscularity and perfectionism were collected. Results: A total of 776 respondents (male: 30.9%; female: 69.1%) aged 19 to 25 years old took part in the study. The overall prevalence of disordered eating was 25.2% (95% confidence interval (CI) 21.9; 28.7) with females (28.6%, 95% CI 24.6; 32.9) higher than males (15.6%, 95% CI 10.5; 21.9). Multivariate analysis showed for both male and female models, perceived sociocultural pressure (male: ß = 1.125, p < 0.01; female: ß = 1.052, p = 0.003), drive for muscularity (male: ß = 1.033, p = 0.017; female: ß = 1.032, p < 0.01) and perfectionism (male: ß = 1.098, p = 0.02; female:ß = 1.119, p < 0.01) were predictors for disordered eating. Conclusion: The prevalence of disordered eating among college and university students in Sarawak was high. The findings suggest that although there were gender differences in the prevalence of disordered eating, its associated factors were the same. The findings of this study will be useful for designing and implementing disordered eating prevention and intervention programme.

ABSTRACT

The aim of this study was to assess the knowledge of East Malaysian adolescents on sexual and reproductive health issues. Data were collected in March-July 2015 from 2858 adolescents aged 13-18 years from selected East Malaysian secondary schools using a self-administered questionnaire. Twelve items relating to sexual and reproductive health were used to measure respondents' knowledge based on their responses 'True', 'False' or 'Don't know', with the proportion of correct answers being the variable of interest. Cronbach's alpha for the twelve items was 0.761 and the mean knowledge score was 6.8. While the majority of the respondents knew that a woman can get pregnant if she has sex with a man and that HIV and AIDS can be transmitted through sexual intercourse, knowledge about Malaysia's abortion laws, that a woman can get pregnant if she has sex only once and that people with sexually transmitted infections may look healthy was poor. Older respondents and those from urban schools reported significantly higher knowledge than younger respondents and those from rural schools, respectively. More emphasis should be given in schools to the specific topics for which low levels of sexual and reproductive health knowledge were found, with greater attention being given to younger adolescents and those in rural areas.

ABSTRACT

OBJECTIVES: Hypertension is a health issue affecting adolescents. Accumulating evidence affirms that elevated blood pressure begins in childhood and tracks into adulthood. This cross-sectional study was conducted to determine the prevalence of elevated blood pressure and its predictors among secondary school students in Sarawak, Malaysia. METHODS: A total of 2,461 secondary school students aged 12-17 years from 19 schools in Sarawak participated in the study. Questionnaire was used to obtain socio-demographic data, parental history of hypertension, and self-reported physical activity. Anthropometric and blood pressure measurements were taken. Data was entered and analysed using SPSS version 23.0. RESULTS: The prevalence of adolescents with elevated blood pressure, overweight, central obesity, and overfat were 30.1%, 24.3%, 13.5%, and 6.7%, respectively. Multivariate logistic regression demonstrated the predictors significantly associated with elevated blood pressure among respondents: overweight (adjusted odds ratio=3.144), being male (adjusted odds ratio=3.073), being Chinese (adjusted odds ratio=2.321) or Iban (adjusted odds ratio=1.578), central obesity (adjusted odds ratio=2.145), being overfat (adjusted odds ratio=1.885), and being an older adolescent (adjusted odds ratio=1.109). Parental history of hypertension, locality, and physical activity showed no significant associations. CONCLUSION: The obesity epidemic must be tackled at community and school levels by health education and regulation of school canteen foods.

ABSTRACT

Rural communities have shown marked increase in metabolic syndrome among young people, with physical inactivity as one of the main contributing factors. This study aimed to determine factors associated with physical inactivity among male and female rural adolescents in a sample of schools in Malaysia. A cross-sectional study was conducted among 145 students aged 13-15 years. Data on socio-demographic, health-related, and psychosocial factors (perceived barriers, self-efficacy, social influences) were collected using a self-administered questionnaire. Anthropometric measurement was taken to generate body mass index (BMI)-for-age, while physical activity (PA) level was assessed using pedometers. The mean steps per day was 6251.37 (SD=3085.31) with males reported as being more active. About 27% of the respondents were either overweight or obese, with more females in this group. There was no significant difference in steps among males and females (p=0.212), and nutritional status (BMI-for-age) (p=0.439). Females consistently scored higher in most items under perceived barriers, but had significantly lower scores in self-efficacy's items. Males were more influenced by peers in terms of PA (p<0.001) and were more satisfied with their body parts (p=0.047). A significantly higher body size discrepancy score was found among females (p=0.034, CI -0.639, -0.026). PA level was low and almost one-third of the respondents were overweight and obese. Female students faced more barriers and had lower self-efficacy with regards PA. Based on the findings, it is recommended that interventions focus on reducing barriers while increasing support for PA. This is particularly important in improving the health status of the youth, especially among the females.

ABSTRACT

Although the association between non-alcoholic fatty liver disease (NAFLD) and metabolic syndrome has been previously firmly established, the prevalence of NAFLD and its risk factors in rural communities remains incompletely defined. This study aimed to determine the prevalence and factors associated with ultrasound-diagnosed NAFLD amongst a rural community in Sarawak. An indigenous village was randomly selected where all adults aged 21 years and above underwent an abdominal ultrasound, biochemical tests and an anthropometric assessment. Respondents with a score > or =8 on an alcohol-use disorders-identification test (AUDIT) indicating harmful or hazardous drinking were excluded. Seventy-seven respondents (46.8% male, mean age 48.4 SD 16.64), met inclusion criteria. The prevalence of ultrasound diagnosed NAFLD was 44.2% (n=34), among them 52.9% had moderate NAFLD. There were no significant age or gender differences between respondents with and without NAFLD, although those with NAFLD were older. Respondents with NAFLD had a significantly higher BMI t,han those without NAFLD (p<0.001). Both male and female respondents with NAFLD had a significantly higher waist circumference than those without NAFLD (p<0.001). Prevalence of diabetes, hypertension, hyperglycemia and hypertriglyceridemia were significantly higher among those with NAFLD. However, there were no significant differences in terms of percentage of unhealthy body fat and muscle, and serum HDL levels. Risk factors independently associated with NAFLD included male gender (odd ratio 0.06; 95% CI 0.008-0.523) and waist circumference (odd ratio 1.2; 95% CI 1.036-1.421). There was a high prevalence of NAFLD and the presence of more severe stages of disease in this indigenous population. Life-style related diseases, such as fatty liver disease, can occur in rural as well as urban populations.

ABSTRACT

Introduction: Hypertension is an emerging health concern among children owing to its increasing prevalence and association with obesity. However, hypertension screening is uncommon, and childhood hypertension-related data are limited. This cross-sectional study determined the prevalence and associated factors of hypertension among primary school children in Kuching, Sarawak. Method: Standard procedures and validated equipment were used to measure blood pressure and anthropometric indicators. The body mass index (BMI)-for-age and waist-to-height ratio (WHtR) were calculated. Questionnaires were used to obtain family sociodemographic data and health history. Results: A total of 1,314 children aged 6-12 years were enrolled, of whom 107 (8.1%) and 178 (13.5%) were hypertensive and pre-hypertensive, respectively. The chi-squared test indicated that hypertension was significantly associated with male sex (P<0.05), >1 standard deviation BMI-for-age (P<0.001), percentage of excess body fat (BF)(P<0.001), 5th to 95th height percentile (P<0.001), >90th excess waist circumference (WC) percentile (P<0.001), >90th WHtR percentile (P<0.001), clerical, service, sales and skilled parental work (P<0.05), excess weight (P<0.05) and cardiovascular disease (P<0.01). Multivariate logistic regression analysis showed that the percentage of excess BF [odds ratio (OR): 4.84, 95% confidence interval (CI): 2.01-11.66] and excess WC (OR: 2.33, 95% CI: 1.15-4.72) were significantly related to hypertension after adjusting for sex and age. Conclusion: The prevalence of hypertension among the study population is higher than that among children worldwide. Childhood hypertension-related factors must be identified to aid in routine blood pressure screening, which is crucial for early detection and intervention to reduce future morbidity burden.

ABSTRACT

Introduction: Most working women experience poor physical and mental health during their postpartum period. This prospective study aimed to describe the physical and mental health issues faced by working mothers during their postpartum period. Methods: Respondents were recruited using the proportional sampling method among mothers who attended the Maternal and Child Health Clinic in the Kuching division in Sarawak, Malaysia. Face-to-face interview was conducted using a questionnaire that consisted of items on socio-demographic data as well as perinatal, prenatal and postpartum factors, and the Edinburgh Postnatal Depression Scale and a checklist of 28 specific postpartum symptoms were used during the first 6 weeks and after 12 weeks of childbirth. Results: A total of 281 respondents participated in this study. Fatigue (42.7%), back or neck pain (36.3%), breast discomfort (16.4%), dizziness (13.5%) and nipple irritation (11.0%) were among the most common symptoms experienced by the mothers during the first 6 weeks after childbirth. There was a significant decrease in the physical symptom scores of the respondents from the first 6 weeks to after 12 weeks of childbirth (1.73±1.96 vs 0.16±0.42; P<0.0005). A significant decrease was also found in the depression scores (6.26±4.26 vs 1.35±1.85, P<0.0005). Conclusion: The prevalence of postnatal depression was higher during the first 6 weeks of postpartum than after 12 weeks of postpartum. Screening and treatment of poor postpartum mental health among working women are essential owing to the impacts on occupational outcomes.

ABSTRACT

Prevention and treatment of childhood obesity is a global concern, and in Malaysia, it is considered a national public health priority. Determinants of childhood obesity are multifactorial and include factors that directly and indirectly influence energy balance-related behaviours, including energy intake and energy expenditure. Interventions to address childhood obesity that have multiple components at different levels have been shown to be the most influential. The ToyBox-study is a childhood obesity intervention aimed at preschool-aged children and their families that had been shown to be effective in several European countries and so was chosen for adaption for the Malaysian setting. Materials were translated and adjusted for the Malaysian context and audience and implemented in kindergartens in Peninsular Malaysia and Sarawak. However, during the COVID-19 pandemic and lockdown, teaching transitioned to being online. This brought an opportunity to reach a wider audience and consider the long-term sustainability of the intervention, and thus eToybox was born. eToybox aims to bring support for healthy energy balance behaviours directly to the teachers, into kindergartens and homes, to encourage families to be active and eat healthily, and prevent or reduce obesity. Through online innovation, the Toybox Study Malaysia programme has been expanded to enhance its potential to impact the promotion of healthy lifestyles among preschoolers and their families, highlighting the importance of a holistic approach to preventing and treating childhood obesity in Malaysia.

ABSTRACT

Introduction: The COVID-19 Movement Control Order (MCO) has caused a concern on the food consumption among university students. This study aimed to assess food diversity and its relationship with accommodation among university students in Sarawak. Method: This cross-sectional study was conducted among students of the University Malaysia Sarawak in Kota Samarahan during the MCO. Data on socio-demographic characteristics and food diversity were collected using an online questionnaire. Results: A total of 478 respondents participated in this study. The majority of the respondents were women (77.4%), and almost half were Malays (49.6%). Half of the respondents stayed at home with their family, while 36.4% stayed in their college dormitories. Except for legumes, nuts and seeds and milk and milk products, all other food groups were common in the respondents' diet, with the highest consumption observed from cereal and cereal products, followed by meat and meat products and water. One-way ANOVA showed that there were significant differences in the intake of fish and seafood; legumes, nuts and seeds; milk and milk products; and fruits between those who stayed in college dormitories, at home with their families and in rented houses (P<0.01). Conclusion: Despite reduction in food availability and accessibility, the total energy intake of the university students did not change. University students should be continuously educated on the importance of a balanced diet consisting of all food groups.

ABSTRACT

BACKGROUND: This study aimed to determine the perceptions and expectations of bone cancer patients with respect to their doctors and the breaking of bad news as well as the environment in which the news was delivered. METHODS: A cross-sectional study using a pretested 41-item questionnaire was conducted using convenience sampling among bone cancer patients in Sarawak General Hospital. Face-to-face interviews were conducted after consent was obtained. Data were analysed using SPSS version 16 (SPSS Inc., IL, US). RESULTS: A total of 30 patients were interviewed. The majority of the respondents were younger than 40-years-old, Malays, and female. All of the respondents perceived that they received news in a comfortable place, agreed that the doctor used simple language and appropriate words during the interaction, and believed that the way the doctor delivered the news might influence their life. The majority of the respondents reported that their news was received without interruption, that the doctor was sitting close but without making physical contact, and time was given for patient to ask questions and they were informed accordingly. CONCLUSION: Delivering bad news regarding cancer is an important communication skill and a complex task that can be learned and acquired. Specially tailored training is proposed to improve medical practice in this area.

ABSTRACT

BACKGROUND: This study aimed to determine the perception and level of safety satisfaction of staff nurses with regards to Occupational Safety and Health (OSH) management practice in the Sabah Health Department, and to associate the OSH management dimensions, to Safety Satisfaction and Safety Feedback. METHODS: A cross-sectional study using a validated self-administered questionnaire was conducted among randomly respondents. RESULTS: 135 nurses responded the survey. Mean (SD) score for each dimension ranged from 1.70 ± 0.68-4.04 ± 0.65, with Training and Competence dimension (mean [SD], 4.04 ± 0.65) had the highest while Safety Incidence was the least score (mean [SD], 1.70 ± 0.68). Both mean (SD) scores for Safety Satisfaction and Safety Feedback was high, 3.28 ± 0.51 and 3.57 ± 0.73, respectively. Pearson's correlation analysis indicated that all OSH dimensions had significant correlation with Safety Satisfaction and Safety Feedback (r coefficient ranged from 0.176-0.512) except for Safety Incidence. CONCLUSION: The overall perception of OSH management was rather low. Significant correlation between Safety Satisfaction and Safety Feedback and several dimensions, suggest that each organization to put in place the leaders who have appropriate leadership and supervisory skills and committed in providing staff training to improve staff's competency in OSH practice. In addition, clear goals, rules, and reporting system will help the organization to implement proper OSH management practice.

ABSTRACT

OBJECTIVES: Physical inactivity is the fourth leading global risk factor for mortality, followed by obesity. The combination of these risk factors is associated with non-communicable diseases, impaired physical function, and declining mental function. The World Health Organization recommends physical activity to reduce the mortality rate. Thus, this study examined the effects on anthropometric measurements of a 12-week walking program for elderly people in Samarahan, Sarawak, Malaysia with a 7000-step goal and weekly group walking activities. METHODS: A quasi-experimental study was conducted involving 109 elderly people with a body mass index (BMI) ≥25.0 kg/m2. BMI, body composition, and average daily steps were measured at baseline, 6 weeks, and 12 weeks. Data were analyzed using SPSS version 26.0, and repeated-measures analysis of variance with the paired t-test for post-hoc analysis was conducted. RESULTS: In total, 48 participants in the intervention group and 61 participants in the control group completed the study. A significant interaction was found between time and group. The post-hoc analysis showed a significant difference between pre-intervention and post-intervention (within the intervention group). The post-intervention analysis revealed an increase in the mean number of daily steps by 3571.59, with decreases in body weight (-2.20 kg), BMI (-0.94 kg/m2), body fat percentage (-3.52%), visceral fat percentage (-1.29%) and waist circumference (-2.91 cm). Skeletal muscle percentage also showed a significant increase (1.67%). CONCLUSIONS: A 12-week walking program combining a 7000-step goals with weekly group walking activities had a significant effect on the anthropometric measurements of previously inactive and overweight/obese elderly people.

ABSTRACT

This study outlines and developed a multilayer perceptron (MLP) neural network model for adolescent hypertension classification focusing on the use of simple anthropometric and sociodemographic data collected from a cross-sectional research study in Sarawak, Malaysia. Among the 2,461 data collected, 741 were hypertensive (30.1%) and 1720 were normal (69.9%). During the data gathering process, eleven anthropometric measurements and sociodemographic data were collected. The variable selection procedure in the methodology proposed selected five parameters: weight, weight-to-height ratio (WHtR), age, sex, and ethnicity, as the input of the network model. The developed MLP model with a single hidden layer of 50 hidden neurons managed to achieve a sensitivity of 0.41, specificity of 0.91, precision of 0.65, F-score of 0.50, accuracy of 0.76, and Area Under the Receiver Operating Characteristic (ROC) Curve (AUC) of 0.75 using the imbalanced data set. Analyzing the performance metrics obtained from the training, validation and testing data sets show that the developed network model is well-generalized. Using Bayes' Theorem, an adolescent classified as hypertensive using this created model has a 66.2% likelihood of having hypertension in the Sarawak adolescent population, which has a hypertension prevalence of 30.1%. When the prevalence of hypertension in the Sarawak population was increased to 50%, the developed model could predict an adolescent having hypertension with an 82.0% chance, whereas when the prevalence of hypertension was reduced to 10%, the developed model could only predict true positive hypertension with a 33.6% chance. With the sensitivity of the model increasing to 65% and 90% while retaining a specificity of 91%, the true positivity of an adolescent being hypertension would be 75.7% and 81.2%, respectively, according to Bayes' Theorem. The findings show that simple anthropometric measurements paired with sociodemographic data are feasible to be used to classify hypertension in adolescents using the developed MLP model in Sarawak adolescent population with modest hypertension prevalence. However, a model with higher sensitivity and specificity is required for better positive hypertension predictive value when the prevalence is low. We conclude that the developed classification model could serve as a quick and easy preliminary warning tool for screening high-risk adolescents of developing hypertension.

ABSTRACT

BACKGROUND AND AIMS: This study aimed to examine the quality of life (QoL) and health satisfaction of undergraduate university students in Sarawak during MCO and its association with socio-demographic profiles. METHODS: In this cross-sectional study, QoL and satisfaction of health of 503 undergraduate university students (63.4% females) from a public university was assessed online using the World Health Organization QoL (WHOQOL)-BREF instrument. RESULTS: The overall QoL and satisfaction with health were 3.7 ± 0.87 and 3.9 ± 0.82, respectively. Male students showed significantly lower mean scores for the environmental domains than female students (63.37 ± 16.21 vs 68.10 ± 14.00, P < .01). Students who lived inside the campus (vs outside campus) showed significantly lower mean score for the physical health (61.49 ± 13.94 vs 67.23 ± 13.93, P < .01), environmental health (58.35 ± 15.07 vs 70.49 ± 13.21, P < .01), overall QoL (3.39 ± 0.90 vs 3.84 ± 0.83, P < .01), and satisfaction with health (3.71 ± 0.90 vs 3.97 ± 0.77, P < .01). Students with parent's income below RM5000 (vs parent's income more than RM5000) had significantly lower mean score for the environmental domain (65.06 ± 14.35 vs 68.20 ± 15.74, P < .05). Others ethnicity scored significantly lower than Bumiputera Sarawak and Malay while Bumiputera Sarawak scored significantly lower than Chinese in physical health domain (Malay = 65.73 ± 13.40, Chinese = 63.24 ± 15.35, Bumiputra Sarawak = 67.35 ± 13.30, Others = 60.84 ± 15.88, P < .05). Malay (69.99 ± 15.20) scored significantly higher than other ethnicities (Chinese = 63.58 ± 15.80; Bumiputera Malaysia = 65.23 ± 13.66; others = 63.98 ± 15.59) in environmental domain (P < .01). When comparing between religions, the results also showed there were significant differences between different religion groups in overall QoL (Islam = 3.75 ± 0.93, Christianity = 3.77 ± 0.79, Others = 3.34 ± 1.14, P < .05), physical health (Islam = 65.00 ± 13.86, Buddhism = 68.40 ± 11.99, Christianity = 64.77 ± 14.94, Others = 61.00 ± 16.03, P < .05), and environmental health (Islam = 69.66 ± 15.48, Buddhism = 64.99 ± 11.36, Christianity = 64.87 ± 15.61, Others = 62.13 ± 16.28, P < .05). CONCLUSION: By understanding university students' QoL in this global disaster, relevant authorities would provide a better rehabilitation and assistance to those affected ones.

ABSTRACT

INTRODUCTION: Many studies had shown that poor growth in children is associated with malnutrition. The underlying factors are diverse, multisectoral and interrelated, ranging from biological to social, cultural and economically related. Because the highest levels of under-nutrition worldwide are found in South Asia, it is essential that policymakers in the region understand the underlying determinants, in order to design effective public health intervention programs. This is especially so if public resources are limited. The purpose of this cross-sectional study was to examine causal relationships among the biological, behavioural and environmental factors related to malnutrition in children aged 5 years and under. METHOD: The instrument used in this study was based on a previously described conceptual framework for malnutrition in children, and tested for its psycometric component, using both qualitative and quantitative methods. As well as the use of a questionnaire, anthropometric and dietary data were collected from 295 children aged 5 years and below, randomly selected from clinics in Tumpat, Kelantan. The proposed model was tested and modified using structural equation modelling (AMOS software: ADC, Chicago, IL, USA). RESULTS: The modified model fitted the data adequately. The results demonstrated that an environmental construct (with factors that included total household income beta = 0.68, p <0.01; total expenditure beta = 0.67, p <0.01; number of rooms in the house beta = 0.46, p <0.01; and socioeconomic status beta = 0.71, p <0.01) had a significant effect on malnutrition. Neither the biological nor behavioural constructs had significant effects. CONCLUSION: These findings provide useful insights into the importance of focusing on environmental factors as the main target when designing intervention programs. This information will be useful for the prioritization of preventive programs when resources are limited, especially in a rural setting. Future studies should focus on the issues of the ability of the households to meet their basic needs, inequality in the population, and the effectiveness of intervention at both micro and macro levels. This study focused on a rural community, therefore the results can only be generalized to areas with similar characteristics.

ABSTRACT

As there are few food frequency questionnaires (FFQ) to assess the dietary intake of preschool children, this study examined the validity and reliability of an FFQ for this purpose. A total of 210 preschoolers aged 4 to 6 years participated in the validation study, while a subsample of 66 participants joined the reliability study. The FFQ is modified from the ToyBox-study and South East Asian Nutrition Surveys (SEANUTS), and comprised 108 food items from 13 food groups. A three-day estimated dietary record (3DR) was used as reference and reliability was assessed through a second administration of the FFQ (FFQ2), four weeks after the first administration (FFQ1). For the validation study, Spearman's correlation coefficients showed moderate to high correlations (p < 0.001) between FFQ and 3DR. Cross-classification of quartile analysis showed moderate agreement between the two methods. As for reliability, Spearman's correlation coefficients showed moderate to high correlations (p < 0.001) between FFQ1 and FFQ2. Cronbach's alpha values (0.708 to 0.824) and intraclass correlation coefficients (0.710 to 0.826) showed good agreement between repeated FFQs. The results suggest that the FFQ has acceptable validity and good reliability. Hence, the FFQ can be used to assess preschool children's food intake.
