We suggest that, by increasing breastfeeding, bedsharing might be protective against SIDS, at least in some contexts. Furthermore, maternal reproductive physiology could be impacted because nursing frequency affects ovulation. This is the first study to directly measure nocturnal breastfeeding behavior in any cultural group.

Using a qualitative approach, the dimensions of subjective well-being of active older adults were outlined and ways identified through which they might be influenced by participation in physical activities. One-to-one and group interviews were used to collect the data. Using cross-case analysis, 17 main themes were identified. The following main dimensions emerged: developmental, material, physical, mental, and social well-being. The findings indicated that physical activity influences all dimensions of the subjective well-being of older adults, with the exception of material well-being. Physical activity appears to contribute to the mental health of older adults through maintenance of a busy and active life, mental alertness, positive attitude toward life and avoidance of stress, negative function, and isolation. The complexity of subjective well-being and the multiple roles of physical activity stress the need to extend qualitative research to sedentary older adults and the institutionalized elderly to explore the relationship between well-being and physical activity in later life.

Twenty years ago a new area of inquiry was launched when anthropologists proposed that an evolutionary perspective on infancy could contribute to our understanding of unexplained infant deaths. Here we review two decades of research examining parent-infant sleep practices and the variability of maternal and infant sleep physiology and behavior in social and solitary sleeping environments. The results challenge clinical wisdom regarding ''normal'' infant sleep, and over the past two decades the perspective of evolutionary pediatrics has challenged the supremacy of pediatric sleep medicine in defining what are appropriate sleep environments and behaviors for healthy human infants. In this review, we employ a biocultural approach that integrates diverse lines of evidence in order to illustrate the limitations of pediatric sleep medicine in adopting a view of infants that prioritizes recent western social values over the human infant's biological heritage. We review what is known regarding infant sleeping arrangements among nonhuman primates and briefly explore the possible paleoecological context within which early human sleep patterns and parent-infant sleeping arrangements might have evolved. The first challenges made by anthropologists to the pediatric and SIDS research communities are traced, and two decades of studies into the behavior and physiology of mothers and infants sleeping together are presented up to the present. Laboratory, hospital and home studies are used to assess the biological functions of shared mother-infant sleep, especially with regard to breastfeeding promotion and SIDS reduction. Finally, we encourage other anthropologists to participate in pediatric sleep research using the unique skills and insights anthropological data provide. By employing comparative, evolutionary and cross-cultural perspectives an anthropological approach stimulates new research insights that influence the traditional medical paradigm and help to make it more inclusive. That this review will potentially stimulate similar research by other anthropologists is one obvious goal. That this article might do so makes it ever more possible that anthropologically inspired work on infant sleep will ultimately lead to infant sleep scientists, pediatricians, and parents becoming more informed about the consequences of caring for human infants in ways that are not congruent with their evolutionary biology.

Exercise referral schemes (ERS) have become a major routeway of promoting physical activity with older adults. However, there is lack of evidence regarding the views of older people and their experience from participating in ERS. The purpose of this study was to offer insights into how physical activity (PA) is situated in notions of successful ageing of people participating in ERS and to highlight points for achieving client-based targets through ERS. Thirteen community-living, retired, older adults (five females) with ages ranging from 63 to 79 who were at various stages in their referral programme were selected from three exercise referral schemes in south west England. The respondents chose to participate in either an individual or a group semi-structured interview. Findings stress that ERS clearly disrupt a lifestyle characterised by growing purposelessness and social isolation, offer older participants better physical and mental function and feelings of accomplishment and success. The participants in this study made a range of personally valued improvements through their involvement in ERS. The success of the programmes relies on the general practitioners' recommendations, the professional help and support from enthusiastic and experienced personnel and the attractiveness of the exercise content which needs to satisfy the multiple needs of the well-being of older adults.

Objective-To examine the promotion of physical activity by general practitioners (GPs) and practice nurses (PNs). Methods-A questionnaire that examined the types of barriers and the levels of their influence as well as stage of change for activity promotion and for personal behaviour was mailed to 846 subjects. Results-The return rate exceeded 70% in each group with a high proportion (69%) of GPs and PNs reporting that they regularly promote physical activity with their patients. GPs were less likely to regularly promote physical activity with their patients if they indicated lack of time as a barrier (odds ratio (OR) = 0.73, 95% confidence interval (CI) 0.58 to 0.93) or lack of incentives (OR = 0.74, 95% CI 0.59 to 0.94), and more likely to promote exercise if they themselves were regular exercisers (OR = 3.19, 95% CI 1.96 to 5.18). However, for PNs longer consultation times (by 1.5 to 2 minutes) had a higher likelihood of producing regular promotion of activity (OR = 1.61, 95% CI 1.02 to 1.62). For PNs personal physical activity stage was the strongest significant predictor of promotion level, but with a stronger eVect (OR = 4.77, 95% CI 1.48 to 15.35) than in the GPs. Conclusion-The main finding is that GPs in the action or maintenance stage of changing their own physical activity are three times more likely to regularly promote the same behaviour in their patients than those in the other stages; for PNs the same diVerence quadruples the likelihood of them promoting physical activity. Professional readiness to change is influenced by known system barriers in GPs, and not in PNs, but is more strongly predicted by personal physical activity behaviour in both groups.

Unhealthy behaviours represent modifiable causes of non-communicable disease. In men, concern focuses on those (i) demonstrating the poorest health, exacerbated by a lack of awareness of the risks that their lifestyles pose and (ii) who neither consult their doctor nor use health services. Classed as 'hard-to-engage', distinctive strategies are needed to reach these men. Impact and process evaluations assessed the effect of a programme of men's health-delivered in/by English Premier League football clubs. Men attended match-day events and/or weekly classes involving physical activity and health education. Validated self-report measures for demographics and lifestyle behaviours were completed pre- and post-intervention. Intention-to-treat analysis was performed on pre-versus-post-intervention differences in lifestyle profiles, whereas interviews (n = 57) provided men's accounts of programme experience. Participants were predominantly white British (70.4%/n = 2669), 18-44 (80.2%/n = 3032) and employed (60.7%/n = 1907). One-third (n = 860) 'never' visited their doctor. Over 85% (n = 1428) presented with combinations of lifestyle risk factors. Intention-to-treat analysis showed improvements (P < 0.001) in lifestyle profiles. Interviews confirmed recruitment of men who were hard-to-engage and unhealthy. Men were attracted through football and/or the clubs, whereas specific design factors impacted on participation. Limitations include use of self-reports, narrow demographics, small effect sizes, lack of follow-up and the absence of non-completers in interviews.
