Abstract

Children living in rural areas are prone to nutritional deficiencies. Low-income levels impact people’s purchasing power so that the intake of most nutrients comes from plant-based foods and consumes less animal food. Nutritional intake greatly affects the development of children’s cognitive function. Brain-derived neurotrophic factor (BDNF) is a group of neurotrophins that contribute greatly to the learning process and memory. This study aims to analyze the relationship between levels of BDNF with the level of intelligence in elementary school children in rural areas of Seluma Regency. This was a cross-sectional study involving 70 elementary school children aged 9-12 years were taken by multi-stage random sampling, who came from 5 districts of Seluma Regency. Blood was collected for measurement of BDNF levels, and stool samples were examined to detect intestinal parasites. The data on respondent characteristics were derived from questionnaires.  Data analysis were done by using the chi-square test. The results of BDNF measurements found 31 children (44.3%) had BDNF levels below the average (<3342.95ng / mL). The results of measuring intelligence level found that 54 children (77.1%) had a level of intelligence below the average. Chi-Square test results obtained p = 0.012 with a PR value of 7.538. There was a significant  association between the BDNF level and intelligence level in elementary school students in the rural area. Elementary school children in rural areas with BDNF levels below the average risk of 7.538 times have below-average intelligence levels.

Abstract

The COVID-19 pandemic is a global concern. In this case, Health Care Workers (HCW) are at the front lines in dealing with the pandemic as they provide diagnosis, care, and treatment. However, their duties have directly placed them at the most at risk of infection. Mitigation and risk reduction are crucial for safeguarding HCWs' health as it prevents the spread of COVID-19. This research aimed to find out the practice of COVID-19 prevention and the correlation among practice and knowledge, attitudes, and personality traits of HCW in Palembang. A cross-sectional study was conducted between May and July 2021 on 255 HCW who have direct contact with patients. The number of respondents per hospital is taken proportionally according to the portion of HCW in each selected hospital. The instrument consisted of demographic variables, knowledge, attitudes, and practices. It proves that it is reliable with Cronbach's alpha value of 0.7. The researchers used descriptive statistics, chi-square, and logistic regression. Overall, 65.2% of participants had good knowledge, 60% had a positive attitude, and 53.3% had good practice. Education (p-value 0.022) and attitude (p-value 0.000) of HCW were all influencing factor in practice. HCW who have a negative attitude are 5.413 times more to have bad practices than those who have a positive attitude (p-value<0.001;PR=5.413). However, training for HCW and further research are recommended to analyze the availability of personal protective equipment, adequate facilities, hospital policies, or other factors that can influence and motivate the practice of HCW.
