The purpose of this study was to assess relations among height, weight, and body mass index (BMI) at different ages from childhood to adulthood, and to examine long-term relations among timing of puberty, height, and BMI. Longitudinal data from the 1958 British birth cohort (all children born between March 3rd and 9th, 1958) were used. Height and weight(More)
OBJECTIVES To assess relations between the adiposity of children and their parents and to establish whether tracking of adiposity from childhood to adulthood varies according to the parental body mass index (BMI). METHODS Longitudinal data from the 1958 British birth cohort study were used (6540 men and 6207 women). The height and weight of the study(More)
This paper reviews child and adolescent adiposity measures and associated long-term health risks. The first section argues that anthropometric measures are practical for large scale epidemiological studies, particularly the body mass index. Limitations of this and other measures are presented. The second section summarises the evidence on the relationship(More)
The study of biodiversity has tended to focus primarily on relatively information-poor measures of species diversity. Recently, many studies of local diversity (alpha diversity) have begun to use measures of functional and phylogenetic alpha diversity. Investigations into the phylogenetic and functional dissimilarity (beta diversity) of communities have(More)

BACKGROUND Higher risks of menstrual problems and infertility have been found in underweight and overweight women but evidence is inconsistent especially in relation to the effect of age of onset of obesity. OBJECTIVE To determine whether body mass index (BMI) in adulthood or childhood affects the reproductive health of women. METHODS Heights, weights(More)
We present a theoretical framework to describe stochastic, size-structured community assembly, and use this framework to make community-level ecological predictions. Our model can be thought of as adding biological realism to Neutral Biodiversity Theory by incorporating size variation and growth dynamics, and allowing demographic rates to depend on the(More)
1. Understanding ecological strategies of invasive species relative to the entire native community is important in understanding and managing both the mechanisms and the potential impacts of invasion, but few studies have taken this approach. 2. We utilize advances in plant ecology to compare functional traits of an invasive shrub species, autumn-olive(More)
Aims The clustering of plants with similar leaf traits along environmental gradients may arise from adaptation as well as acclimation to heterogeneous habitat conditions. Determining the forces that shape plant leaf traits requires both linking variation in trait morphology with abiotic gradients and linking that trait variation with plant performance under(More)
An association between obesity and back pain has been observed, but the underlying causal direction is uncertain. We examined the temporal sequence among back pain, BMI, and weight gain using data from the 1958 British birth cohort followed to age 33 (4395 men and 4468 women). Heights and weights were measured at ages 7 and 33, and self-reported at age 23.(More)
