METHODS AND STUDY DESIGN: This study had two phases: a cross-sectional growth study of under-five Orang Asli children (N=304; Phase 1) and a 2-year prospective cohort growth study of Orang Asli children aged 0-3 years (N=214; Phase 2) in the Temerloh district of Pahang, Malaysia. Weight-for-age, length/height-for-age, weight-for-length/height, and body mass index-for-age were determined.
RESULTS: The prevalence rates of stunting, underweight, wasting, and thinness in under-five Orang Asli children (Phase 1) were 64%, 49%, 14%, and 12%, respectively. In the cohort of 214 children (Phase 2), weight-for-age was initially documented and maintained closely at -1.50 standard deviations (SD) in the first 6 months, but it declined to approximately -2.00 SD at 15 months and remained close to -2.00 SD thereafter. Length/height-for-age declined rapidly to approximately -2.50 SD at 18 months and fluctuated between -2.30 and -2.50 SD thereafter. Weight-for-length/height increased sharply to -0.40 SD at 2-3 months, declined gradually to less than -1.00 SD at 12 months, and plateaued between -1.00 and -1.30 SD thereafter.
CONCLUSIONS: Undernutrition is prevalent among Orang Asli children, with length rather than weight faltering being more pronounced in the first 2 years of life. Identifying the causes of early growth retardation in this population is required to inform future preventive strategies.
METHODS AND STUDY DESIGN: A randomized controlled intervention study was carried out to determine the impact of self-efficacy education based on the Health Belief Model (HBM) in 240 patients with type 2 diabetes at the Golestan Hospital, Ahvaz, Iran between October 2014 and August 2015. The education duration was three months followed by a 24-week follow-up visit to determine the progress of the subjects. In this study, reliable and validated diabetes educational booklet and questionnaires based on knowledge, health beliefs and quality of life were used. The participants were randomly allocated to either the intervention group (n=120) or to the conventional dietary counseling group as controls (n=120), and assessed at the baseline, week 12 and week 36. The study was divided into primary outcome measurements consisting of glycated hemoglobin A1c (HbA1c), fasting blood glucose, lipid profile, and anthropometric levels. Secondary outcome measures were related to nutrition knowledge, health beliefs and quality of life.
RESULTS: The results showed that subjects in the intervention group had significantly better metabolic and glycemic profiles compared with those in the control group. It also showed that knowledge, health belief and quality of life significantly increased in the intervention group.
CONCLUSIONS: Findings indicate that through tailored self-efficacy education, the quality of life and metabolic profile of diabetes patients can be improved.
METHODS AND STUDY DESIGN: We searched Medline, Embase, Cochrane Central Registry of Controlled Trials and CINAHL. Clinical trials were eligible if they compared palm oil-rich diets with diets rich in MUFAs or PUFAs. We pooled results of included studies using a random effects model and assessed the quality of the evidence and certainty of conclusions using the GRADE approach.
RESULTS: Intake of palm oil intake compared to oils rich in MUFA was associated with increased levels of total cholesterol (TC) [mean difference (MD)=0.27 mmol/L; 95% CI 0.08 to 0.45], LDL-C (MD=0.20 mmol/L; 95% CI 0.02 to 0.37) and HDL-C (MD=0.06 mmol/L; 95% CI 0.02 to 0.10). Similarly, for comparison with oils rich in PUFAs, palm oil showed increased in TC (MD=0.38 mmol/L; 95% CI 0.14 to 0.62), LDL-C (MD= 0.44 mmol/L; 95% CI 0.01 to 0.88) and HDL-C (MD=0.08 mmol/L; 95% CI 0.03 to 0.13). For both comparisons, there were no significant effects on triglycerides.
CONCLUSIONS: Even though palm oil increases marginally the level of serum lipids, the evidence is mostly of low to moderate quality.
