Birth spacing and child mortality in bangladesh and the Philippines

This analysis uses data from Bangladesh and the Philippines to demonstrate that children who are born within 15 months of a preceding birth are 60 to 80% more likely than other children to die in the first two years of life, once the confounding effects of prematurity are removed. The risks associated with short conception intervals are confined to children who are also high birth order; they persist in the presence of controls for prior familial child mortality, breast-feeding, mother's age, and socioeconomic status. In Bangladesh but not in the Philippines, these effects are confined to the neonatal period.     

Improving Primary Care for Persons with Disabilities: the nature of expertise

It has been well documented that persons with disabilities (PWDs) have a more vulnerable health status than persons without disabilities; yet, they often receive inadequate primary care within the US health care system. This study explores how PWDs think about the health care they receive, particularly how primary care providers facilitate or hinder quality care for PWDs. The findings from this study expand the concept of expertise in health care, suggesting it goes well beyond technical competence of health care providers. For PWDs, expertise is multi-dimensional, not solely the domain of providers and includes having knowledge and using that knowledge within the context of the provider-patient relationship. PWDs identified three distinct areas of expertise: medical/technical, medical/biographical, and systems. Expertise can be brought to health care encounters by both PWDs and providers, and it can be developed through collaboration during interactions between providers and PWDs.

Accuracy of death certificate ages for the extreme aged

This study attempts to verify age reporting on the death certificate for the “extreme aged” population and to evaluate the accuracy of recent death rates for this group in light of the findings. In addition, methods used and problems encountered in carrying out a record linkage study, particularly a low match rate, are identified. A sample of more than three thousand death records was selected from those filed for decedents age 85 and over in Pennsylvania and New Jersey in the 1968 to 1972 period. Death certificates of 53 percent of whites and 30 percent of nonwhites were linked to the 1900 U.S. Census. A comparison of age on the death certificate with the age reported for the same individual in the census record showed a high level of agreement for whites, except at ages 100 and over; for nonwhites, however, age agreement levels were substantially lower. Within racial groups, there was little difference by sex in agreement on age. These results, corroborating those of earlier studies, make it clear that nonwhite mortality at the oldest ages has been consistently understated in official statistics.
