Validation of a Sustainable Diet Index among young Malaysian adults

@#Introduction: A sustainable diet which is healthy and environmentally friendly provides the means of climate change mitigation in addition to promoting health of the population. There is an urgent need to have an indicator to measure if one’s diet is sustainable. This paper aimed to validate a newly developed Sustainable Diet Index (SDI) among young Malaysian adults. The SDI was developed based on the dietary guidelines of a sustainable diet. Methods: Five indicators (rice, animal-based food, plant-based food, food waste, and packaging) were included in the SDI. The index was validated via content validity, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) among young Malaysian adults. The dietary assessment tool used was an Android application named Sustainable Food Record. Results: Content validity showed fair to moderate correlations (0.331 - 0.816) between the indicators in the SDI. EFA produced five final factors with eight indicators in the index as follows: 1) fruits and vegetables; 2) dairy, eggs, and meat; 3) rice, cereals, and grain products; 4) food packaging; and 5) food waste management with strong factor loadings (0.760 – 0.984). All five factors with eight indicators were retained and proceeded with CFA. The fit indices from CFA demonstrated that the model was an absolutely fit. Conclusion: The validated SDI can be used as a tool to measure the sustainability of an individual’s diet in Malaysia, incorporating both health and environment considerations.

Psychometric Validation Of The Bahasa Malaysia Version Of The Eortc QLQ-C30 In Malaysian Colorectal Cancer Patients

@#This study aimed to assess the validity and reliability of the Bahasa Malaysia (BM) version of European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire core (QLQ-C30) (version 3.0) in Malaysian patients with colorectal cancer. A cross sectional study design was used to obtain data from patients receiving treatment at two teaching hospitals in Kuala Lumpur, Malaysia. Self-administered method was used. Statistical analysis included reliability, convergent and discriminant validity and known-groups comparisons. Statistical significance was based on p value ≤ 0.05. The internal consistency Cronbach’s alpha coefficient (α) was acceptable (> 0.70) in all scales but cognitive (α = 0.56) and pain in patients with stoma bag (α = 0.35). Test-retest coefficients were high (r = 0.93 to 1.00). All items showed adequate convergent validity (r > 0.40) except for questionnaire item 5 “needs help in eating/dressing/washing”. Similarly, criteria for discriminant validity were achieved in all but item 10 “need rest”. Patients with high Karnofsky Performance Scores (KPS) scores reported significantly less dyspnoea (p = 0.021) and appetite loss (p = 0.047) compared to patients with low KPS scores. There was no significant difference between patients with and without stomas. The psychometric properties of the BM version of the QLQ-C30 were comparable to previous studies in other settings. Therefore, the questionnaire could be used to measure quality of life in Malaysian patients with colorectal cancer.

Handgrip Strength and Its Associated Factors among Community-dwelling Elderly in Sri Lanka: A Cross-sectional Study

PURPOSE: Low muscle strength is central to geriatric physical disabilities and mortality. The purpose of the present study was to examine handgrip strength (HGS) and its associated factors among community-dwelling older people in Sri Lanka. METHODS: A cross-sectional study was conducted in the Kandy district using multistage sampling. A total of 999 older people were recruited, with a female preponderance. Data were collected using interviewer-administered questionnaires on demographic characteristics, depression, and physical activity. Anthropometric measurements including weight, height, mid-upper arm circumference, calf circumference, and HGS were recorded. Complex sample general linear model was used to examine the association between HGS and its associated factors. RESULTS: The mean highest HGS of the study group was 12.56 kg (95% confidence interval: 11.94–13.19). Male older people had a higher HGS (17.02, 95% confidence interval: 15.55–18.49 kg) than females (10.59, 95% confidence interval: 10.12–11.06 kg). For both men and women, older age was associated with lower HGS, while mid-upper arm circumference was associated with better HGS. Diabetes mellitus, vegetarian diet, and alcohol consumption were associated with HGS for women only. CONCLUSION: Men had a higher HGS compared with women. Age, mid-upper arm circumference, diabetes mellitus, vegetarian diet, and alcohol consumption were factors associated with HGS among community-dwelling older people in Kandy district, Sri Lanka. HGS can be used as a feasible strategy to improve health status of older people by community health nurses.

Traditional and Complementary Medicine (TCM) among Study Population with Cardiovascular Risk; use and Substitution for Conventional Medicine in Pahang, Malaysia

Introduction: Cardiovascular diseases are the main cause of morbidity and mortality in Malaysia. There is evidence of high traditional and complementary medicine (TCM) use among population with cardiovascular risk and there have been anecdotal reports about substitution of conventional medicines with TCM. We investigated the prevalence of TCM use, treatment preference and substitution of conventional medicines in study population with cardiovascular risk factors in Pahang, Malaysia. Methods: A cross-sectional survey was conducted using an interviewer-administered questionnaire in five districts of Pahang. A total of 1250 households were chosen through proportionate and systematic sampling. Respondents aged 18 years and above were selected. Results: The study population with cardiovascular risk factors who used TCM was higher than the general population (31.7% versus 25.9%). There were no clear preferences in using TCM by gender, age groups, educational level and income even though other bumiputeras showed a slight inclination towards TCM use. Among the study population with cardiovascular risk factors who consumed TCM, 20-30% of them were using TCM as a substitute for their conventional medications. Respondents from the younger age group (18-40 years) (57.1%), highest educational level (43.2%), other bumiputeras (38.4%) and highest income group (31.4%) preferred the combination of both conventional and traditional medicine. Conclusion: TCM use among population with cardiovascular risk factors is high. The high preference for combination therapy of TCM and conventional medications among young adults and the use of TCM to substitute conventional medications show that much research is needed to provide proven TCM therapies to avoid self-mismanagement of cardiovascular risk in Malaysia.

Predictors of sustained six months quitting success: efforts of smoking cessation in low intensity smoke-free workplaces

<p><b>INTRODUCTION</b>This study aims to identify the predictors of a 6-month quitting success among employees involved in workplace smoking cessation with low-intensity smoke-free policy.</p><p><b>MATERIALS AND METHODS</b>A multicentre prospective cohort study was conducted among employees from 2 different public universities in Malaysia. Interventions include at least 2 sessions of behavioural therapy combined with free nicotine replacement therapy (NRT) for 8 weeks. Participants were followed up for 6 months. Independent variables assessed were on sociodemographic and environmental tobacco smoke. Their quit status were determined at 1 week, 3 months and 6 months.</p><p><b>RESULTS</b>One hundred and eighty- five smokers volunteered to participate. Among the participants, 15% and 13% sustained quit at 3 months and 6 months respectively. Multivariate analysis revealed that at 6 months, attending all 3 behavioural sessions predicted success. None of the environmental tobacco exposure variables were predictive of sustained cessation.</p><p><b>CONCLUSION</b>Individual predictors of success in intra-workplace smoking cessation programmes do not differ from the conventional clinic-based smoking cessation. Furthermore, environmental tobacco exposure in low intensity smoke-free workplaces has limited influence on smokers who succeeded in maintaining 6 months quitting.</p>

Anxiety status and its relationship with general health related quality of life among prostate cancer patients in two university hospitals in Kuala Lumpur, Malaysia

This study aimed to determine the prevalence of anxiety among prostate cancer patients, and to ascertain the association between stress status, socio-demographic, medical and surgical illness, current urinary problem and cancer status with general health-related quality of life [HRQOL] among these patients. A hospital based, cross sectional study was conducted at Surgical Clinic, University Malaya Medical Centre [UMMC] and Universiti Kebangsaan Malaysia Medical Centre [UKMMC] using universal sampling. A total of 193 patients were recruited. The prevalence of anxiety was 25.4% [95%CI: 19.2 - 31.6]. The anxiety ratings were mild anxiety [10.4%], moderate anxiety [13.6%] and severe anxiety [1.6%]. The total quality of life among stress group was 59.2 +/- 14.7 and among non-stress group was 73.9 +/- 12.7. There was a significant negative weak correlation between anxiety score and total quality of life [r[s]=-0.534, P<0.001]. In multivariable analysis, there was a significant difference in the total quality of life [QOL] among anxiety status [adj. mean diff. = -9.1 [95%CI: -15.2, -4.7]]. The adjusted mean difference was associated by age category of the patients [P<0.001]; living partner [P<0.001]; in-termittency [P=0.035] and problem of hematuria during micturition [P=0.005]. The prevalence of anxiety among prostate cancer was moderately high. Treating the urination problem as well as encouraging living with spouse/family may improve the quality of life among anxiety condition of these patients
