Abstract: Iodine deficiency disorder (IDD) remains a significant global public health problem. The aim of this study was to assess the prevalence of IDD amongst Orang Asli in semi-urban areas. A cross sectional study was conducted in April of 2006 in whom 346 children and adult women participated. UIC was performed in 97 (28.0%) pre-school children (PSC) aged 1-6 years old, 115 (33.2%) primary school going children (SGC) aged 7-12 years old and 134 (38.8%) adult women (≥ 15 years old). The median UIC of the studied popu… Show more

Sociodemographic, nutritional, and environmental factors are associated with cognitive performance among Orang Asli children in Malaysia

et al. 2019

Children aged 2 to 6 years are in a crucial period of growth development, during which it is important for them to attain specific cognition related to concentration and attention so that they can perform well in school later in life. Various factors influence children’s cognition during this crucial period. However, to date, only a limited number of studies have examined the cognitive performance of underprivileged children living in poverty, particularly indigenous children (also known as Orang Asli children in Malaysia). Therefore, this cross-sectional study aimed to determine the associations between sociodemographic factors, nutritional factors (body composition and hemoglobin), and environmental factors (home environment and parasitic infections) with cognitive performance among Orang Asli children in Negeri Sembilan, Malaysia. The participants were 269 children (51% boys, 49% girls) aged 2 to 6 years ( M = 4.0, SD = 1.2 years) and their mothers, from 14 Orang Asli villages. Face-to-face interviews were conducted with the mothers, and the children’s cognitive performance, operationalized as working memory index (WMI), processing speed index (PSI), and cognitive proficiency index (CPI), was assessed using the Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition (WPPSI-IV). The children’s weight and height were measured, and their blood and stool samples were collected to assess hemoglobin level and parasitic infections, respectively. Multiple linear regression analysis showed that the father’s years of education ( β = 0.262–0.342, p < 0.05), availability of learning materials at home ( β = 0.263–0.425, p < 0.05), and responsiveness of the parent to the child ( β = 0.192–0.331, p < 0.05) were consistently associated with all three cognitive indices (WMI, PSI, and CPI). A holistic approach involving parents, communities, and government agencies should be established to improve the cognitive performance of these underprivileged children.

In spite of the high prevalence of overweight and obesity among the Orang Asli (OA) of Malaysia being an increasing concern due to the associated adverse health implications, information regarding this issue is scarce. This cross-sectional study is aimed to investigate the predictors of overweight and obesity and its association with blood pressure and quality of life among Senoi OA women. A total of 19 villages at Batang Padang, Perak, were selected out of a total of 56 villages using a simple random sampling, in which 355 Senoi OA women were participated in the study. Face-to-face interviews were conducted to obtain information on sociodemographic characteristics, dietary intake, physical activity, and quality of life. Weight, height and blood pressure were also measured. The prevalence of overweight and obesity were 32.4% and 26.2%, respectively. In terms of multiple linear regression, monthly household income, total energy intake, and metabolic equivalents (METs) for domestic activities were found to have significantly contributed to body mass index (BMI). Furthermore, BMI contributed significantly towards levels of blood pressure and quality of life after controlling for monthly household income, total energy intake, and METs for domestic activities. In conclusion, there should be urgent attention to poverty and overweight/obesity among the OA women. The findings would aid in alerting policy makers and health professionals as underweight is no longer a sole nutritional problem among OA but it appears to be coexisting with overweight and obesity. Strategies for improving their socioeconomic status, promoting a balanced and moderate diet, and encouraging involvement of OA women in physical activities should be implemented to prevent overweight and obesity.

Since most of the central regions of the European part of Russia are considered selenium and iodine deficient, the assessment of modern real consumption of chlorine, bromine, iodine and selenium by population of these regions with different diets is an important constituent part of medical monitoring. In this paper, a brief analysis of the impact of these elements on the human body is given. A number of consumed foodstuffs in different food rations (diets) were assessed. Six selected basic food rations, which most fully reflect the specific features of nutrition in the Russian Federation, were chosen. The analysis of the concentration of chlorine, bromine, iodine and selenium in a wide range of food and agricultural products was carried out. The daily intake of these elements in the human body from the selected diets was calculated. A comparison of the real income of chlorine, bromine, iodine and selenium in the human body with a physiologically needed intake was performed. It is proposed to use the coefficient of Kr, which is the ratio of actual intake of the element in the human body to physiologically needed intake. Based on this analysis assessed insufficient or excess supply of chlorine, bromine, iodine and selenium in the human body with these diets in the central regions of the European part of Russia was evaluated.
