Estimates of life expectancy gains from reducing/eliminating major causes of death in the USA: An update analysis for population in 2001--2008

Evaluation of the impact of a disease on life expectancy is an important part of public health. Potential gains in life expectancy (PGLE) that can properly take into account the competing risks are an effective indicator for measuring the impact of the multiple causes of death. This study aimed to measure the PGLEs from reducing/eliminating the major causes of death in the USA from 2001 to 2008. To calculate the PGLEs due to the elimination of specific causes of death, the age-specific mortality rates for heart disease, malignant neoplasms, Alzheimer disease, kidney diseases and HIV/AIDS and life table constructing data were obtained from the National Center for Health Statistics, and the multiple decremental life tables were constructed. The PGLEs by elimination of heart disease, malignant neoplasms or HIV/AIDS continued decreasing from 2001 to 2008, but the PGLE by elimination of Alzheimer's disease or kidney diseases revealed increased trends. The PGLEs (by years) for all race, male, female, white, white male, white female, black, black male and black female at birth by complete elimination of heart disease 2001–2008 were 0.336–0.299, 0.327–0.301, 0.344–0.295, 0.360–0.315, 0.349–0.317, 0.371–0.316,0.278–0.251, 0.272–0.255, and 0.282–0.246 respectively. Similarly, the PGLEs (by years) for all race, male, female, white, white male, white female, black, black male and black female at birth by complete elimination of malignant neoplasms, Alzheimer's disease, kidney disease or HIV/AIDS 2001–2008 were also uncovered, respectively. Most diseases affect specific population, such as, HIV/AIDS tends to have a greater impact on people of working age, heart disease and malignant neoplasms have a greater impact on people over 65 years of age, but Alzheimer's disease and kidney diseases have a greater impact on people over 75 years of age. To measure the impact of these diseases on life expectancy in people of working age, partial multiple decremental life tables were constructed and the PGLEs were computed by partial or complete elimination of various causes of death during the working years. Thus, the results of the study outlined a picture of how each single disease could affect the life expectancy in age-, race-, or sex-specific population in USA. Therefore, the findings would not only assist to evaluate current public health improvements, but also provide useful information for future research and disease control programs.^

Sudden Infant Death disparities: A systematic review on health education and policy recommendations for decreasing Sudden Infant Death in the African-American community

Objective: To perform a systematic review of the literature on SIDS and SUID deaths concentrated in the African-American community, describe health education and policy recommendations and recommend a new approach that may aid in decreasing the disparity of infant mortality in the African-American community. ^ Methods: The PubMed database was systematically searched to identify relevant articles for final review and analysis. Using the CASP 2006 system to critique literature, twelve articles were found that met inclusion and exclusion criteria. ^ Results: Evidence in the literature confirmed there was a current disparity among African Americans' infant mortality rates in comparison to other US ethnic groups. The underlying reasons for these disparities included the following maternal and infant characteristics: mothers younger than eighteen, having more than one live infant, having a high school education or less, never been married, and have infants born preterm or with low birth weight. Maternal smoking, substance abuse, and breastfeeding did not have a significant impact on infant sleep environments among African Americans. ^ Conclusion: Tailored health education programs at the community level, better access to pre-pregnancy and prenatal care, and increased maternal perception of risk that is relevant to the infants sleeping environment are all possible solutions that may decrease African American infant mortality rates.^
