Periconceptional maternal vitamin supplementation and childhood leukaemia: An uncertainty analysis
BACKGROUND: Recent studies in childhood cancer suggest that maternal vitamin supplementation may reduce the risk of leukaemia, neuroblastoma and certain types of childhood brain tumours. For example, a previous study found a significantly reduced risk of acute lymphoblastic leukaemia (ALL) but not acute myeloid leukaemia (AML) in children with Down syndrome whose mothers reported any vitamin supplement use prior to knowledge of pregnancy (ALL OR …
Random-digit dialing for control selection in childhood cancer studies: The geographic proximity and demographics within matched sets
The purpose of this analysis was to evaluate the degree of matching in 95 individually matched pairs from a case-control study of childhood leukemia that used random-digit dialing to select control subjects. Both geographic proximity (of each case subject to his or her matched control subject) and differences in socioeconomic status were evaluated. The median distance between matched pairs was 3.2 km. There were no significant differences in dist…

Analysing open birth interval distributions
This paper began with the recognition that open birth interval distributions are analogous to age distributions. It then became clear that closed birth interval distributions are, somewhat more loosely, analogous to mortality schedules, and that the relationship between open and closed birth interval distributions could be explored by imitating the formal demography of mortality and age distribution. Pursuing this programme, we develop the formal…
A Gompertz model for birth interval analysis
During recent years birth intervals have been analysed on a life table basis. This method retains both closed and open intervals, and so reflects behaviour that deliberately avoids the next birth entirely. When life tables are prepared separately for each birth order, markedly different patterns of movement toward the next birth can appear from one parity to the next. This is illustrated for Korean survey data, with historical trends given across…
Changes in acceptors' and users' ages: A test of an explanatory mechanism
Acceptors in national family planning programmes are becoming steadily younger, with fewer children. In the present analysis, which makes use of the computerized component projection scheme CONVERSE, it is shown that saturation of the older groups with users has a relatively minor role to play in reducing the mean age of new acceptors. Even where acceptance and continuation rates are high and follow the usual pattern of higher levels for the olde…
