Based on the new patterns, schools must offer larger amounts of fruits, grains, and proteins/meats to children;the amounts of fluid foods (milk and juice) remained the same. This study examined the effect of the new food pattern on student’s consumption and food cost. Methods: The amounts and cost of foods served and wasted for one week in first grade students attending two elementary schools (n = 812) were measured. One school received the current SBP pattern (control breakfast, average number of students attending breakfast n = 81), the other school’s breakfast reflected the proposed changes (test breakfast, n = 82). To test the hypothesis that the test breakfast leads to significantly increased food cost and food waste compared to the control breakfast, the weekly average amount of the served solid and fluid foods (grams and milliliters) as well as their waste were compared between the two groups using paired student’s t-test in STATA 11 (significance at p-value < 0.05). Results: Data confirmed the hypothesis in that the test breakfast was associated with significantly higher food cost (by approximately $100/week) and solid food waste but there was no change in milk and juice consumption. Conclusions: This exploratory study indicates that a significant portion of the additional foods served to first-graders to improve their nutritional status were not consumed but wasted. Further studies in larger samples and including students from all grades are needed to examine this issue fully.展开更多

Malnutrition compromises the child’s immune system leading to direct mortality and increased vulnerability to infectious diseases stunting and poor brain development. This study sought to analyze the food consumption patterns of children 3 - 5 years old attending Mateka Primary school, Bungoma County. This study adopted a cross sectional survey. One hundred and twenty five (125) children selected from three ECD classes in the school formed the sample size. Purposive and simple random sampling techniques were used to select the study area and the children respectively. Structured questionnaires were administered to the caregivers of the children. Information on demographics, socio-economic status, and food consumption patterns were gathered. Food consumption patterns were assessed using a HDDS and a quantitative food frequency questionnaire. Socio-demographic data was analyzed using (SPSS) Version 21 (2007) and dietary data was analyzed using Nutri-Survey for Windows (2007). Results revealed that most of the households were of low socio-economic characteristics. The most consumed foods were cereals, roots and tubers. Majority (55.2%) of the children had low dietary diversity, 29.1% had medium dietary diversity and 15.7% had greater dietary diversity. The children were deficient in energy, protein, Vitamin A, Iron and Zinc. It can be concluded that the diets fed to the children are inadequate to meet their nutrient intakes for physiological development and growth. Further research should be done to document the prevalence of micronutrient malnutrition among the children.展开更多

Methicillin resistant Staphylococcus aureus (MRSA) is a strain of Staphylococcus aureus which is resistant to methicillin. There are two types of MRSA: Community acquired methicillin resistant Staphylococcus aureus (CA-MRSA) and hospital acquired methicillin resistant Staphylococcus aureus (HA-MRSA). MRSA in the community presents a significant reservoir that could enter into healthcare facilities and spread among patients and also a risk for immune compromised persons in the community. Methodology: The study aimed at determining the prevalence of MRSA isolated from toilet and classroom door handles as a potential source of infection to the students and the workers in selected schools in Nairobi, Kenya. The study also compared the prevalence of MRSA between boarding and non-boarding girls, boys and mixed (both girls and boys in the same school) secondary schools. Twelve secondary schools in Nairobi County were randomly selected and 306 samples from both the toilet and classroom door handles were collected using sterile swabs and transported to the laboratory. Isolation of Staphylococcus aureus was done by the use of selective media Mannitol salt agar, antibiotic susceptibility of isolates was done by disk diffusion method, and molecular detection of mecA and PVL genes were done by polymerase chain reaction (PCR). Results: The prevalence of S. aureus was 20% and 15% were MRSA positive by both Antimicrobial Susceptibility Test and PCR detection. 20% showed the presence of PVL genes, 8% showed the presence of both genes and 56% of isolates with mecA gene had PVL genes. Conclusion: The presence of MRSA in this study emphasizes the need to formulate hygiene measures to prevent possible spread of MRSA and other transmissible pathogens to students and workers in the schools.展开更多
