Does worksite social capital enhance retention into a worksite weight-loss programme?

Objective

To determine if worksite social capital predicted retention in a worksite‐based weight‐loss programme using structural equation modelling. A secondary aim was to determine if worksite social capital was related to changes in weight at 6 months.

Methods

Overweight or obese employees from 28 worksites enrolled in a larger 12‐month worksite weight‐loss trial. Workplace social capital was assessed using an eight‐item scale specific to the workplace. Weight was measured using a HealthSpot^tm, and change in weight was computed from weigh‐ins at baseline and 6 months and reported as pounds (lbs) lost. Retention was defined as those employees who completed a weigh‐in at 6 months.

Results

Across the trial, N = 1,790; age = 46.6 ± 11; 73% women; 73% White overweight or obese employees participated. The odds of participant attrition were 1.12 times greater with each unit decrease in social capital score at baseline (p < 0.05), and while the model testing the direct effect of social capital at baseline on weight loss at 6 months demonstrated acceptable fit, social capital was not a significant predictor of weight loss (p > 0.05).

Conclusions

Increased worksite social capital was predictive of retention in a worksite weight‐loss programme. To maximize return on investments for employee wellness and weight‐loss programmes, employers may benefit from understanding the facets of the ‘social’ environment such as social capital that may increase the likelihood of sustained participation.

What are dental non-attenders' preferences for anxiety management techniques? A cross-sectional study based at a dental access centre

OBJECTIVE

Dental anxiety is a barrier to attendance. Dental non-attenders may seek emergency care and may prefer to receive anxiety management measures for treatment required. Little is known about the preferences of these dental non-attenders for different anxiety management techniques. Understanding such preferences may inform management pathways, improve experiences, alleviate anxieties and encourage a more regular attendance pattern. As such, the aim of this study was to gain a greater understanding of the dental anxiety of patients attending a dental access centre for emergency dental treatment and to ascertain preferences for different anxiety management techniques.

DESIGN

Cross-sectional study involving self-completed questionnaires and clinical observation.

SETTING

NHS Dental Access Centre, York, UK.

SUBJECTS AND METHODS

Two hundred participants not registered with a general dental practitioner, aged 18 years or over, experiencing pain and self-referred were recruited on a consecutive sampling basis. Participants completed a questionnaire eliciting demographic and dental history details, dental anxiety and preferences for dental anxiety management options.

MAIN OUTCOME MEASURES

Correlation of the modified dental anxiety scale with preference for different dental anxiety management techniques.

RESULTS

No significant predictive factors were found that explained preferring local anaesthetic to sedation, or general anaesthesia for restorations or extractions. Those highly anxious were less likely to consider tell-show-do techniques (p=0.001) or watching explanatory videos (p=0.004) to be helpful for overcoming their anxieties than the low or moderate anxiety groups.

CONCLUSIONS

People attending access centres may represent a group who are unwilling to explore non-pharmacological methods to overcome their anxieties. This supports the need for sedation to provide treatment. Future work may include exploring in more depth the thoughts and opinions of this group of patients to improve understanding of their complex dental attitudes. From this, more effective strategies may be developed to encourage regular dental attendance.

Older inpatients' room preference: single versus shared accommodation

INTRODUCTION

The Royal Victoria Hospital, a geriatric medicine assessment and rehabilitation hospital in Edinburgh, was re-provided into a new 130 bed purpose-built unit on the Western General Hospital site in June 2012. All patient rooms in the new unit are single occupancy with en-suite facilities.

METHODS

We surveyed inpatients on their room preference in 2008 and repeated the survey with inpatients in the new unit in 2013. Patients were asked whether they would prefer to be in a shared room or a single room and to explain the reason behind their choice. They were also asked whether they would prefer to eat their meals in a day/dining room or by their bed. The patients in the 2013 survey were also questioned as to whether they felt lonely in their single room. Forty-three inpatients agreed to participate in the 2008 survey and 46 in the 2013 survey. All had an abbreviated mental test score≥8/10. In 2008, those surveyed had a mean age of 78. In 2013, the mean age was 83.

RESULTS

In 2008, 37.2% of patients expressed a preference for single room accommodation, whereas in 2013, 84.8% said that they preferred a single room. The majority of patients, 60.5% in 2008 and 76.1% in 2013, preferred to eat their meal at their bedside. Only 8.7% of patients in 2013 would consider eating in a day/dining room compared with 34.9% in 2008. In the 2013 survey, 60.9% of patients reported that they never felt lonely in a single room.

DISCUSSION

The benefits of single room versus multi-occupancy room hospital accommodation has been recently debated. The results from our survey indicate a marked difference in the preference for a single room between 2008 and 2013. The introduction of open visiting and care rounding has reduced the risk of isolation in single rooms. Our survey introduces new discussion about social isolation, privacy, noise levels and patient well-being and recovery.

Body condition constrains immune function in field populations of female Australian plague locust Chortoicetes terminifera

The insect innate immune system comprises both humoral and cellular defence responses. In the laboratory, the insect immune system is well characterized. In the field, however, little is known about the role of constitutive insect immune function and how it varies within and between populations. Laboratory studies suggest that host nutrition has significant impact upon insect immune function. Thus, the rationale for this study was to sample natural populations of the Australian Plague Locust Chortoicetes terminifera to establish whether locust body condition (as determined by protein and lipid content) impacted their constitutive immune system and, as a result, has the potential to impact on their capacity to respond to a pathogenic challenge. We found that body condition varied greatly between individual female locusts within sites and that haemolymph protein levels, but not body lipid content, varied between sites. Moreover, our measures of immune function were correlated with the haemolymph levels of protein (in the case of haemocyte density), lipid (prophenoloxidase activity) or both (lysozyme-like antimicrobial activity). We discuss the implications of these findings for the role of biological pesticides in the control of locust populations.
