  • We aimed to explore the population dynamics of snail in 3 sites of the White Nile in Sudan. More specifically, we aimed to investigate the annual patterns of snail populations that act as intermediate hosts of schistosomes and monthly snail infection rates and ecological characteristics presumably related to snail populations. We collected snails for 1 year monthly at 3 different shore sites in the vicinity of El Shajara along the White Nile river in Khartoum State, Sudan. In addition, we measured air and water temperatures, water turbidities, vegetation coverages, and water depths and current speeds. Most of the collected snails were Biomphalaria pfeifferi and Bulinus truncatus. The population densities of snails and their infection rates varied across survey sites. The collected snails liberated S. mansoni and S. haematobium cercariae as well as Amphistome and Echinostome cercariae. Infected snails were found during March-June. The ecological characteristics found to be associated with the absence of snails population were: high turbidity, deep water, low vegetation coverage (near absence of vegetation), high water temperature, and high current speed. To our knowledge, this is the first longitudinal study of the snail population and ecological characteristics in the main basin of the White Nile river.

  • Objectives: This study evaluated usual dietary intakes of total fat and fatty acids among the Korean population based on the revised Dietary Reference Intakes for Koreans 2020 (2020 KDRIs). Methods: This study utilized data from the eighth Korea National Health and Nutrition Examination Survey (KNHANES 2019-2021). We included 18,895 individuals aged 1 year and above whose 1-day 24-hour dietary recall data were available. To calculate the external variability using the National Cancer Institute 1-day method, data from the U.S. NHANES 2017-March 2020 Pre-pandemic dataset were employed. The total fat and fatty acid intake were evaluated based on the Acceptable Macronutrient Distribution Ranges (AMDRs) and Adequate intake (AI) of 2020 KDRIs for each sex and age groups. Results: Approximately 86% of the Korean population obtained an adequate amount of energy from total fat consumption (within the AMDRs), indicating an appropriate level of intake. However, the percentage of individuals consuming saturated fatty acids below the AMDR was low, with only 12% among those under 19 years of age and 52% aged 19 years and older. On a positive note, approximately 70% of the population showed adequate consumption of essential fatty acids, exceeding the AI. Nevertheless, monitoring the intake ratio of omega 3 (n-3) to omega 6 (n-6) fatty acids is essential to ensure an optimum balance. Conclusions: This study explored the possibility of estimating the distribution of nutrient intake in a population by applying the external variability ratio. Therefore, if future KNHANES conduct multiple 24-hour recalls every few years-similar to the U.S. NHANES-even for a subset of participants, this may aid in the accurate assessment of the nutritional status of the population.

  • Background: Most studies of human papilloma virus (HPV) are aimed at the natural history of the infection and its relation to cancer; however, there are few studies to assess knowledge of the general population. Our aim was analyze the degree of knowledge of Argentinians about HPV infection and its prevention. Materials and Methods: We conducted a voluntary, anonymous and non-binding survey with 27 multiple-choice items, in twelve private and public establishments, selected to include a broad population in terms of education, age and gender. The survey consisted of three sections: individual characteristics of the volunteer, HPV infection basic knowledge, its prevention and the virus relationship with other cancers. Results: One thousand two hundred ninety seven volunteers aged 18 to 80 participated. The total number of correct answers was 45.1%. The correct answers for relationship HPV and cervical cancer was 62.1%. Almost 55% did not know about types of HPV that the vaccines for protection. Statistical analysis showed that women, single people, workers, the better educated, those who have had a STDs or HPV and receiving information through medical or educational establishments had greater knowledge of the topic. Only 0.2% of participants answered all questions correctly. Conclusions: Knowledge plays an important role in health care and the deficiency found in our population could influence the success of the measures taken in the fight against cervical cancer. In this regard, we believe it would be appropriate, not only to emphasize early diagnosis and vaccine implementation, but also incorporate new communication strategies, facilitating reception of accurate and precise information by all strata of society.

  • Objective: The objective of this study is to identify the risk factors for falls among the Korean elderly population. Methods: We analyzed the data on 167 persons of 65 years of age or older who have experienced falls drawn from the Third Korea National Health and Nutrition Examination Survey. We conducted a cross-tabulation analysis and logistic regression analysis of the impact of the socio-demographic characteristics, health-related behavior, mobility, and morbidity upon the frequencies of falls. Results: Among the socio-demographic characteristics, gender(p<0.001), marital status(p<0.1), and the type of medical insurance(<0.1) were found to be statistically significant, Among the constraints on mobility, the severity of walking problems, (p<0.001) and depression(p<0.05) proved to be significant, As for variables related to health-related behavior, the level of routine physical activities (p<0.001) was found significant, Finally, rheumatism(p<0.1), osteoporosis(p<0.05), diabetes(p<0.1), urinary incontinence(p<0.01) were also significant. A logistic regression analysis of the incidence of falls revealed that urinary incontinence was the most important risk factor with an odds ratio of 2.7. Conclusion: Although a variety of factors affect the frequencies of falls in the elderly population, urinary incontinence proved to be the single most important risk factor. This finding implies that education for fall prevention is crucial for those with urinary incontinence.

  • The statistics of occupational injuries and illnesses is one of the most important indicators of worker's safety and health in the field of occupational safety and health. The conventional statistics was produced without consideration of gender difference. This study was planned to investigate the difference of occupational injuries and illnesses by gender because that recently female workers was increased through the change of industrial structure such as from manufacturing dominated to service dominated structure. Statistics of occupational injuries and illnesses collected by workmen's compensation insurance system that have no information about gender composition of population. Economically active population survey was used to calculated the rate of occupational injuries and illnesses by gender. The distribution of estimated rate of occupational injuries and illnesses by industry, occupation and the type of accident were different between male and female employees, but those by the size of enterprise, age of the injured, the duration of the first recuperation, and job tenure were similar between male and female employees. This study has shown that gender sensitive approach may be applied to policy of occupational safety and health because that gender neutral perspective may not discover the fact of gender specific problems.
