Assessing Biological Mortality Bias From Deciduous Tooth Emergence
Cortisol Stability at 16 and 30 Years in Urine Specimens Stored at −20°C
These results suggest that urinary cortisol remains largely intact and measurable in specimens stored at -20°C for three decades, and there is a strong correlation between cortisol measured after 16 and 30 years in storage

Controlling for Landform Age When Determining the Settlement History of the Kuril Islands
Archaeological investigations of settlement patterns in dynamic landscapes can be strongly biased by the evolution of the Earth's surface. The Kuril Island volcanic arc exemplifies such a dynamic landscape, where landscape-modifying geological forces were active during settlement, including sea-level changes, tectonic emergence, volcanic eruptive processes, coastal aggradation, and dune formation. With all these ongoing processes, in this paper w…

Longitudinal analysis of permanent tooth emergence in Japanese children
Permanent tooth emergence was examined in a sample of 114 Japanese children (63 girls and 51 boys) born in Tokyo in 1914 and 1924. Subjects were enrolled as young infants from households spanning a wide range of socioeconomic conditions, without regard to parental income or occupation. The children were prospectively examined up to age 20 years with observations of permanent tooth emergence recorded to the nearest two or three months. Parametric …
Distribution of postpartum amenorrhea in rural Bangladeshi women
Previous studies of postpartum amenorrhea (PPA) demonstrated distinct subgroups of women with short and long durations of amenorrhea. This phenomenon was attributed to cases where breastfeeding is absent because of pregnancy loss or infant death, or confusion of postpartum bleeding with resumption of menses. We explored these ideas using data from an 11‐month prospective study in Bangladesh in which 858 women provided twice‐weekly interviews and …
Longitudinal analysis of deciduous tooth emergence
Emergence of the deciduous teeth is generally considered to be robust to moderate environmental insults, malnutrition, and disease. Consequently, deciduous tooth emergence has been used to assess growth and development and for age estimation in children. In this paper, we examine the way in which nutritional status and other covariates affect deciduous tooth emergence in a sample of 114 Japanese children born in Tokyo in 1914 and 1924. Parametric…
Patterns for the initiation of breastfeeding in humans
Establishment of lactation has important biological and emotional health consequences for the newborn. Even so, substantial variation within a culture and among different cultures is seen in the onset of breastfeeding. Parametric mixture models are used to explore this variation and to uncover general human patterns for the initiation of breastfeeding. The model components reflect two hypothesized patterns of behavior. The first component is a “n…
Regression‐based prediction of net energy expenditure in children performing activities at high altitude
We developed a simple, non-invasive, and affordable method for estimating net energy expenditure (EE) in children performing activities at high altitude. A regression-based method predicts net oxygen consumption (VO(2)) from net heart rate (HR) along with several covariates. The method is atypical in that, the "net" measures are taken as the difference between exercise and resting VO(2) (DeltaVO(2)) and the difference between exercise and resting…
Longitudinal analysis of deciduous tooth emergence
Previous studies, mostly in European populations, found sex differences in the pattern of deciduous tooth emergence. Most studies find that the anterior dentition in males is precocial relative to the female dentition, and the pattern reverses so that females lead males in the emergence of the posterior deciduous dentition. Less is known about sex differences in the dental development and emergence of non‐European populations. Here we examine the…
Mortality models for paleodemography
Introduction Population scientists concerned with long-term trends in human mortality ought to be interested in skeletal samples from extinct communities. Such samples are, in principle, the only possible source of information for most pre-industrial populations lacking written records – by far the most common kind of human community that has ever existed. Samples of skeletons provide two broad classes of information of potential interest to demo…
Colostrum Feeding Behaviour and Initiation of Breast-Feeding in Rural Bangladesh
Human breast milk is primarily colostrum immediately following birth. Colostrum gradually changes to mature milk over the next several days. The role of colostrum in fighting infections and promoting growth and development of the newborn is widely acknowledged. This role is mediated by differences across cultures in the acceptability of colostrum and the prevalence of colostrum feeding. This study examined the prevalence of colostrum feeding and …
Menstrual cycle variability and the perimenopause
Menopause, the final cessation of menstrual cycling, occurs when the pool of ovarian follicles is depleted. The one to five years just prior to the menopause are usually marked by increasing variability in menstrual cycle length, frequency of ovulation, and levels of reproductive hormones. Little is known about the mechanisms that account for these characteristics of ovarian cycles as the menopause approaches. Some evidence suggests that the dwin…
Principles of population genetics
Longitudinal analysis of deciduous tooth emergence
We present a form of parametric survival analysis that incorporates exact, interval-censored, and right-censored times to deciduous tooth emergence. The method is an extension of common cross-sectional procedures such as logit and probit analysis, so that data arising from mixed longitudinal and cross-sectional studies can be properly combined. We extended the method to incorporate and estimate a proportion of agenic teeth. While we concentrate o…

A Multistate Model of Fecundability and Sterility
This paper develops a multistate hazards model for estimating fecundability and sterility from data on waiting times to conception. Important features of the model include separate sterile and nonsterile states, a distinction between preexisting sterility and sterility that begins after initiation of exposure, and log-normally distributed fecundability among nonsterile couples. Application of the model to data on first birth intervals from Taiwan…
Hazards models for human population biology
Population biologists are often interested in examining the effects of continuous biological variables such as measures of growth, body size, nutritional status, and exposure to environmental risk factors, on discerte vital events such as brith, onset of disease, and death. Traditional statistical analyses are unable to cope with several complexities that arise in the study of such effects, including censoring of observations and explanatory vari…
Longitudinal analysis of deciduous tooth emergence in Indonesian children. I. Life table methodology
Deciduous tooth emergence was investigated in a sample of 468 children from central Java. The subjects were examined every 35 days for up to 2 years. Statistics on the timing of emergence for each tooth were derived from actuarial life table estimates, and male and female survivorship curves of tooth emergence were compared for statistical sex differences. Javanese children exhibited delayed emergence compared to other populations. No overall pat…
Determination of sex from arm bone measurements
Discriminant function analysis has been applied to numerous dimensions of the cranial and postcranial skeleton for sex determination of U.S. blacks and whites and is extended here to five measurements of the arm and wrist. These include maximum lengths of the long arm bones in addition to two measurements that reflect wrist breadth. Our results indicate that whites are more accurately classified than blacks, but seven of the 31 possible measureme…
