For more than 20 years the Bogalusa Heart Study has been collecting data on children's dietary intakes in a biracial community. The macronutrient contribution of children's diets is similar to that in diets of adolescents: 13% of energy from protein, 49% from carbohydrate, and 38% from fat. As children get older, mean intakes of vitamins and minerals per 1,000 kcal decrease. Ten-year-old children in 1987-1988 were 3 lb heavier than 10-year-olds in 1973-1974. Yet total energy intakes remained virtually the same from 1973 to 1988. The composition of macronutrients shifted over the 15-year period, with an increase in the percentage of energy from protein and carbohydrate and a decrease in the percentage of energy from total fat, particularly saturated fat. Dietary cholesterol intake also decreased as a result of a decrease in egg consumption. Although the diets of children changed positively from 1973 to 1988, more than 75% of children consumed more total fat, saturated fat, and cholesterol than the recommended amounts. School meals had a major impact on the diets of children. School breakfast and lunch, together, contributed approximately 50% of the day's total intake of energy, protein, cholesterol, carbohydrate, and sodium. About 40% of daily total fat intake came from school breakfast and lunch. The diets of children in the Bogalusa study are similar to those reported in national studies of children. What might be different, however, are the types of foods consumed and their contribution to intakes of specific nutrients. An understanding of the diet and nutrition habits of children is critical to the planning of intervention strategies that will assist us in meeting our dietary goals for Healthy People 2000.

Background

Hospital‐acquired hepatitis B virus (HBV) infection has been well described and continues to occur worldwide. Recent nosocomial outbreaks have been linked to unsafe injection practices, use of multi‐dose vials, and poor staff compliance with standard precautions. This report describes a nosocomial outbreak that occurred in a pediatric hematology and oncology unit of a large academic hospital, the epidemiological investigation of the outbreak, and preventive measures implemented to limit further in‐hospital transmission.

Methods

Outbreak investigation including contact tracing and HBV screening were initially carried out on all patients seen by the unit during the same period as the first three cases. Routine screening for the entire patient population of the unit was initiated in February 2013 when it was realized that numerous patients may have been exposed.

Results

Forty‐nine cases of HBV infection were confirmed in 408 patients tested between July 2011 and October 2013. Phylogenetic analysis of the HBV preC/C gene nucleotide sequences revealed that all tested outbreak strains clustered together. Most (67%) patients were HBeAg positive. The cause of transmission could not be established. Preventive measures targeted three proposed routes. HBV screening and vaccination protocols were started in the unit.

Conclusions

The high number of HBeAg positive patients, together with suspected lapses in infection prevention and control measures, are believed to have played a major role in the transmission. Measures implemented to prevent further in‐hospital transmission were successful. On‐going HBV screening and vaccination programs in pediatric hematology and oncology units should become standard of care. Pediatr Blood Cancer © 2015 Wiley Periodicals, Inc.  相似文献
