Children with obese mothers, low family incomes, and lower cognitive stimulation have significantly elevated risks of developing obesity, independent of other demographic and socioeconomic factors. In contrast, increased rates of obesity in black children, children with lower family education, and nonprofessional parents may be mediated through the confounding effects of low income and lower levels of cognitive stimulation.

Introduction: The issue of occupational therapy's professional identity has been debated for many years and continues today. Lack of clarity has resulted in occupational therapists' perceptions of holding a low status and of colleague and public misunderstanding. Method: A range of international literature was reviewed. Inductive analysis elicited two major themes-reasons for issues with identity and the consequences of issues with identity. The development of communities of practice is discussed. Results: The analysis of the causes and consequences of issues with professional identity was used to suggest how the profession might become a mature community of practice. Lack of deep knowledge of the profession's unique beliefs was shown to cause inconsistent messages about its identity. Consequently, practitioners believed they were undervalued. Understanding, owning and reinforcing an occupational paradigm were seen as vital elements for creating professional communities of practice. Conclusion: To function as a community of practice requires occupational therapists to use a range of strategies that reinforce their unique occupation-based practice. Where all members commit to a single set of values and beliefs this can afford a unique identity, reinforced by the ability to demonstrate and articulate this through a clear, single message.

Participating in leisure is known to enhance physical wellbeing, mental health and social functioning. There is, however, little knowledge of the current level of engagement in leisure occupations by older adults in the United Kingdom. Therefore, the aim of this study was to explore the current leisure occupations of adults over 60 years who considered themselves to be healthy and to identify the motivations that underpinned participation in those occupations.Structured interviews were conducted with 70 adults with a mean age of 72 years. The majority of the participants (51, 73%) reported engaging in leisure occupations. The range of leisure occupations was wide and included walking, sailing, listening to music, emailing and volunteering. Of these, 23% were active leisure, 18% passive leisure, 24% social leisure, 20% hobbies and 15% other leisure occupations. Content analysis was adopted to explain the motivators for taking part in these leisure occupations. It was found that enjoyment, pleasure and relaxation were the key motivators.This study shows that the majority of well older people are participating in leisure occupations and feeling positive about doing so. Further research is required to establish the role that occupational therapists can have in encouraging older adults to continue with or develop new leisure occupations to enhance health and quality of life.

Synthesis, secretion and post-translational proteolysis of the storage proteins in cotyledons of Lupinus angustifolius L. (lupin) have been examined in vivo and in vitro by using a combination of pulse-chase experiments with [3H]- or [35S]-labelled amino acids, subcellular fractionation and cell-free translation from poly(A)+ (polyadenylylated) RNA or membrane-bound polyribosomes. Related polypeptides were identified by immunoprecipitation, separation on sodium dodecyl sulphate/polyacrylamide gels and fluorography. The synthesis and processing of two proteins were compared. Conglutin alpha, the 11 S protein, was found as a family of precursor polypeptides of Mr 68000-88000 when translated from poly(A)+ RNA under conditions where signal segments were not cleaved, and Mr 64000-85000 both when sequestered into the endoplasmic reticulum and when accumulated in the protein bodies. Pulse-chase labelling showed that cotyledons from early stages of development were completely incapable of further proteolysis of these precursors. Nevertheless, in the same juvenile cotyledons, the precursors of the minor storage protein conglutin gamma, two polypeptides with Mr 50000-51000, were proteolytically cleaved to mature subunits of Mr 32000 and 17000 within 2 h. Further cleavage of the precursors of conglutin alpha into families of mature subunits of Mr 21000-24000 and 42000-62000 was detected in more mature cotyledons. A model is proposed which suggests that the mature subunits are produced by a single proteolytic cleavage of each of the three major precursors of conglutin alpha and also suggests that a close similarity exists between these subunits and those of other legumin-like proteins. The enzyme responsible for this cleavage, which appears at a specific stage in the middle of cotyledonary development, seems to be an integral part of the programmed developmental sequence in these pods.
