Effects of a Community-Based Healthy Lifestyle Intervention Program (Co-HELP) among Adults with Prediabetes in a Developing Country: A Quasi-Experimental Study.

BACKGROUND: The prevalence of type 2 diabetes among Malaysian adults has increased by more than two folds over the past two decades. Strategies to collaborate with the existing community partners may become a promising channel for wide-scale dissemination of diabetes prevention in the country. The objectives of this study were to determine the effects of community-based lifestyle interventions delivered to adults with prediabetes and their health-related quality of life as compared to the usual care group. METHODS: This was a quasi-experimental study conducted in two sub-urban communities in Seremban, Malaysia. A total of 268 participants with prediabetes aged between 18 to 65 years old were assigned to either the community-based lifestyle intervention (Co-HELP) (n = 122) or the usual care (n = 146) groups. The Co-HELP program was delivered in partnership with the existing community volunteers to incorporate diet, physical activity, and behaviour modification strategies. Participants in the Co-HELP group received twelve group-based sessions and two individual counselling to reinforce behavioural change. Participants in the usual care group received standard health education from primary health providers in the clinic setting. Primary outcomes were fasting blood glucose, 2-hour plasma glucose, and HbA1C. Secondary outcomes included weight, BMI, waist circumference, total cholesterol, triglyceride, LDL cholesterol, HDL cholesterol, systolic and diastolic blood pressure, physical activity, diet, and health-related quality of life (HRQOL). RESULTS: An intention-to-treat analysis of between-groups at 12-month (mean difference, 95% CI) revealed that the Co-HELP participants' mean fasting plasma glucose reduced by -0.40 mmol/l (-0.51 to -0.28, p<0.001), 2-hour post glucose by -0.58 mmol/l (-0.91 to -0.24, p<0.001), HbA1C by -0.24% (-0.34 to -0.15, p<0.001), diastolic blood pressure by -2.63 mmHg (-3.79 to -1.48, p<0.01), and waist circumference by -2.44 cm (-4.75 to -0.12, p<0.05) whereas HDL cholesterol increased by 0.12 mmol/l (0.05 to 0.13, p<0.01), compared to the usual care group. Significant improvements were also found in HRQOL for both physical component (PCS) by 6.51 points (5.21 to 7.80, p<0.001) and mental component (MCS) by 7.79 points (6.44 to 9.14, p<0.001). Greater proportion of participants from the Co-HELP group met the clinical recommended target of 5% or more weight loss from the initial weight (24.6% vs 3.4%, p<0.001) and physical activity of >600 METS/min/wk (60.7% vs 32.2%, p<0.001) compared to the usual care group. CONCLUSIONS: This study provides evidence that a culturally adapted diabetes prevention program can be implemented in the community setting, with reduction of several diabetes risk factors and improvement of HRQOL. Collaboration with existing community partners demonstrated a promising channel for the wide-scale dissemination of diabetes prevention at the community level. Further studies are required to determine whether similar outcomes could be achieved in communities with different socioeconomic backgrounds and geographical areas.

Does change in perception following counseling result in improved quitting outcome among Malaysian smokers?

OBJECTIVE: The authors examined the effects that change in perception about the advantages and disadvantages of smoking and quitting had on quitting outcome among smokers enrolled in a program for smoking cessation. METHODS: A total of 185 smokers from 2 public universities who were interested in quitting received smoking cessation counseling on understanding the risks and benefits of quitting (or smoking) in addition to a course of free nicotine replacement therapy (NRT). A decisional balance questionnaire (DBQ) was administered at baseline and at 2 months postcounseling to determine and assess changes in smoking perception. RESULTS: After counseling, 72.3% of smokers had reduced their perceptions about the advantages of smoking, and 66.4% had increased perceptions of disadvantages of smoking. At the eighth week, 51 participants (27%) had quit. Smokers who had reduced perceptions of the advantages of smoking had significantly higher quit rates compared with those with no improvement in perception (82.6% vs 17.4%; odds ratio = 2.47; 95% confidence interval = 1.00-6.10). CONCLUSION: After counseling, smokers did change their perception of the advantages and disadvantages of smoking during the quitting process. These changes are associated with a higher likelihood of smoking cessation.

Gender-dependent association of a ß(2)-adrenergic gene variant with obesity parameters in Malaysian Malays.

Recent findings have shown that the rs1042714 (Gln27Glu) single-nucleotide polymorphism (SNP) on the ß2-adrenoceptor gene may predispose to obesity. The findings from other studies carried on different populations, however, have been inconsistent. The authors investigated the association between the rs1042714 SNP with obesity-related parameters. DNA of 672 Malaysian Malays was analyzed using real-time polymerase chain reaction. Univariate and multivariate linear regression analyses revealed significant associations between rs1042714 and diastolic blood pressure in the pooled Malaysian Malay subjects under additive and recessive models. After gender stratification, however, a significant association was found between the rs1042714 and triglyceride and the rs1042714 and log-transformed high-density lipoprotein cholesterol levels in Malaysian Malay men. No significant association was found between the SNP and log-transformed body mass index. This polymorphism may have an important role in the development of obesity-related traits in Malaysian Malays. Gender is an effect modifier for the effect of the rs1042714 polymorphism on obesity-related traits in Malaysian Malays.

Effect of vitamin D supplementation on cardiometabolic risks and health-related quality of life among urban premenopausal women in a tropical country--a randomized controlled trial.

BACKGROUND: Many observational studies linked vitamin D to cardiometabolic risks besides its pivotal role in musculoskeletal diseases, but evidence from trials is lacking and inconsistent. AIM: To determine whether Vitamin D supplementation in urban premenopausal women with vitamin D deficiency can improve cardiometabolic risks and health-related quality of life (HRQOL). DESIGN: A double-blind randomized controlled trial was conducted in Kuala Lumpur, Malaysia. A total of 192 vitamin D deficient (<50 nmol/l) premenopausal women were randomized to receive either vitamin D 50,000 IU or placebo once a week for 2 months and then monthly for 10 months. Primary outcomes were serum 25(OH)D, serum lipid profiles, blood pressure and HOMA-IR measured at baseline, 6 months and 12 months. HRQOL was assessed with SF-36 at baseline and 12 months. RESULTS: Ninety three and ninety-nine women were randomised into intervention and placebo groups respectively. After 12 months, there were significant differences in the serum 25(OH)D concentration (mean difference: 49.54; 95% CI: 43.94 to 55.14) nmol/l) and PTH levels (mean difference: -1.02; 95% CI: -1.67 to -0.38 pmol/l) in the intervention group compared to placebo group. There was significant difference between treatment group in both serum 25(OH)D and PTH. There was no effect of supplementation on HOMA-IR, serum lipid profiles and blood pressure (all p>0.05) between two groups. There was a small but significant improvement in HRQOL in the components of vitality (mean difference: 5.041; 95% CI: 0.709 to 9.374) and mental component score (mean difference: 2.951; 95% CI: 0.573 to 5.329) in the intervention group compared to placebo group. CONCLUSION: Large and less frequent dosage vitamin D supplementation was safe and effective in the achievement of vitamin D sufficiency. However, there was no improvement in measured cardiometabolic risk factors in premenopausal women. Conversely vitamin D supplementation improves some components of HRQOL.

The experiences of suffering of palliative care patients in Malaysia: a thematic analysis.

A qualitative study was conducted with semi-structured interviews to explore the experiences of suffering in 20 adult palliative care inpatients of University Malaya Medical Centre. The results were thematically analyzed. Ten basic themes were generated (1) loss and change → differential suffering, (2) care dependence → dependent suffering, (3) family stress → empathic suffering, (4) disease and dying → terminal suffering, (5) health care staff encounters → interactional suffering, (6) hospital environment → environmental suffering, (7) physical symptoms → sensory suffering, (8) emotional reactions → emotional suffering, (9) cognitive reactions → cognitive suffering, and (10) spiritual reactions → spiritual suffering. An existential-experiential model of suffering was conceptualized from the analysis. This model may inform the development of interventions in the prevention and management of suffering.

The experiences of suffering of palliative care informal caregivers in Malaysia: a thematic analysis.

A qualitative study was conducted with semi-structured interviews to explore the experiences of suffering in 15 palliative care informal caregivers in University Malaya Medical Centre. The data were thematically analyzed. Seven basic themes were generated (1) empathic suffering, (2) anticipatory grief, (3) obsessive-compulsive suffering, (4) helpless-powerless suffering, (5) obligatory suffering, (6) impedimental suffering, and (7) repercussion suffering. A model of compassion suffering was conceptualized from the analysis. This model may serve as a guide in the assessment and management of suffering in palliative care informal caregivers.

Association of melanocortin-4 receptor gene polymorphisms with obesity-related parameters in Malaysian Malays.

BACKGROUND: Melanocortin-4 receptor (MC4R) is an important regulator of body weight and energy intake. Genetic polymorphisms of the MC4R gene have been found to be linked to obesity in many recent studies across the globe. AIM: This study aimed to examine the effects of MC4R polymorphisms on obesity parameters, Linkage disequilibrium (LD) pattern and haplotypes in Malaysian Malays. METHODS: The study subjects were 652 Malaysian Malays. Genomic DNA was extracted from buccal swabs. Genotyping was performed using Sequenom MassARRAY® iPLEX platform. Anthropometric and blood lipid profiles were measured. RESULTS: MC4R rs571312 SNP was associated with logBMI (p = 0.008) and systolic blood pressure (p = 0.005), while MC4R rs2229616 SNP was associated with total cholesterol (TC) levels (p = 0.016). The MC4R rs7227255 SNP did not show any association with obesity parameters. CONCLUSIONS: The strength of LD of the MC4R gene region is low and the haplotypes were not associated with obesity in Malaysian Malays.

Can initial perceptions about quitting predict smoking cessation among Malaysian smokers?

Perceived risks and benefits of quitting smoking may be important factors in successful treatment. This study examined the association between initial perceived risks and benefits of quitting smoking and outcomes during a two month smoking cessation attempt. Participants (n = 185) were treatment-seeking smokers attending two smoking cessation clinics in Klang Valley, Malaysia. They received structured behavioral therapy and free Nicotine Replacement Therapy (NRT). Prior to treatment, a 12 item Perceived Risks and Benefits Questionnaire (PRBQ) was administered. This was used to assess the smoker's initial perceptions during their quit attempt. Participants were re-contacted at the end of two months to determine their smoking status. The results show participants intending to quit demonstrated a greater understanding of the benefits of quitting smoking than the risks of quitting. Those with a higher education level had a greater understanding of the benefits of quitting (p = 0.02). PRBQ items, such as perceived risks of quitting (ie weight gain, negative affect, social ostracism, loss of enjoyment and craving) were not associated with abstinence at two months. However, those who perceived a benefit of higher physical attraction post-cessation were less likely to have stopped smoking at two months (OR 0.18; 95% CI 0.08-0.45). Other perceived benefits at baseline, such as health, general well-being, self-esteem, finances and social approval, were not associated with smoking cessation at two months. The results suggest that in our study population, smokers' baseline perceptions of the benefits of cessation of smoking prior to therapy are not associated with quit results at two months. Counseling patients regarding the advantages and disadvantages of quitting may have changed their perceptions during quitting process and should be further explored in future studies.

General health related quality of life and associated factors among prostate cancer patients in two tertiary medical centers in Kuala Lumpur, Malaysia: a cross-sectional study.

Measurement of quality of life among prostate cancer patients helps the health care providers to understand the impact of the disease in the patients' own perspective. The main aim of this study is to measure the quality of life among prostate cancer patients at University Malaya Medical Center (UMMC) and Universiti Kebangsaan Malaysia Medical Centre (UKMMC) and to ascertain the association factors for physical coefficient summary (PCS) and mental coefficient summary (MCS). A hospital based, cross sectional study using the Short Form-36 (SF-36) questionnaire was conducted over a period of 6 months. A total of 193 respondents were recruited. Their total quality of life score was 70.1± 14.7 and the PCS score was lower compared to MCS. The factors associated for PCS were: age, living partner, renal problem, urinary problem of intermittency, dysuria and hematuria. Factors associated for MCS were: age, living partner, renal problem, presenting prostatic specific antigen and urinary problem of intermittency and dysuria. Our prostate cancer patients had moderate quality of life in the physical health components but their mental health was less affected.

Predictors of smoking cessation among staff in public Universities in Klang Valley, Malaysia.

Smoking cessation studies are often performed in clinic based settings. The present example aimed to find predictors of success among staff in worksite smoking cessation programmes in two major public universities in Klang Valley, Malaysia. All staff from both universities received an open invitation via staff e-mail and letters to participate. At the start of treatment, participants were administered the Rhode Island Stress and Coping Questionnaire and Family Support Redding's Questionnaire. Behaviour therapy with free nicotine replacement therapy (NRT) were given as treatment. After two months, they were contacted to determine their smoking status. 185 staff from University A (n=138) and University B (n=47), responded and voluntarily showed interest to quit. There was no significant difference in respondents with respect to socio demographic characteristics and smoking history. After two months of treatment, quit rates were 24% in University A vs. 38 % in University B (p>0.05). Univariate predictors of cessation were adherence to NRT (p<0.001), smoking fewer cigarettes per day (p<0.05) and the number of behaviour therapy sessions attended (p<0.001). Logistic regression identified 3 significant predictors of smoking cessation. Participants attending more than one session (OR= 27.00; 95% CI : 6.50; 111.6), and having higher pre-treatment general stress (OR= 2.15; 95% CI: 1.14; 4.05) were more likely to quit, while a higher number of cigarettes smoked (OR= 0.19: 95% CI: 0.06; 0.59) reduced the likelihood of quitting. Increasing age, ability to cope with stress and family support were not significant predictors. We conclude that factors such as the number of counseling sessions, the amount of cigarettes smoked at baseline, adherence to NRT and pretreatment stress are important considerations for success in a worksite smoking cessation programme.
