I'm searching for solutions: why are obese individuals turning to the Internet for help and support with 'being fat'?

INTRODUCTION: This study explores what types of information obese individuals search for on the Internet, their motivations for seeking information and how they apply it in their daily lives. METHOD: In-depth telephone interviews with an Australian community sample of 142 individuals with a BMI ≥ 30 were conducted. Theoretical, purposive and strategic samplings were employed. Data were analysed using a constant comparative method. RESULTS: Of the 142 individuals who participated in the study, 111 (78%) searched for information about weight loss or obesity. Of these, about three quarters searched for weight loss solutions. The higher the individual's weight, the more they appeared to search for weight loss solutions. Participants also searched for information about health risks associated with obesity (n = 28), how to prevent poor health outcomes (n = 30) and for peer support forums with other obese individuals (n = 25). Whilst participants visited a range of websites, including government-sponsored sites, community groups and weight loss companies, they overwhelmingly acted upon the advice given on commercial diet websites. However, safe, non-judgemental spaces such as the Fatosphere (online fat acceptance community) provided much needed solidarity and support. CONCLUSIONS: The Internet provides a convenient source of support and information for obese individuals. However, many turn to the same unsuccessful solutions online (e.g. fad dieting) they turn to in the community. Government and community organisations could draw upon some lessons learned in other consumer-driven online spaces (e.g. the Fatosphere) to provide supportive environments for obese individuals that resonate with their health and social experiences, and address their needs.

Obese adults' perceptions of news reporting on obesity: the panopticon and synopticon at work

News reporting, in channels such as broadcast and print media, on obesity as an issue has increased dramatically in the last decade. A qualitative study, in which we used in-depth interviews and thematic analysis, was undertaken to explore 142 obese individuals’ perceptions of, and responses to, news reporting about obesity. Participants believed that news reporting on obesity focused on personal responsibility and blame, and portrayed obese people as “freaks.” They described being portrayed as “enemies” of society who were rarely given a voice or identity in such news coverage unless they were seen to be succeeding at weight loss. They were also critical of the simplistic coverage of obesity, which was in contrast with their personal experiences of obesity as complex and difficult to address. Participants believed that obesity news reporting added to the discrimination they experienced. We consider how this news reporting may act as a form of “synoptical” social control, working in tandem with wider public health panoptical surveillance of obesity.

Synergistic effects of sodium lauroyl sarcosinate and glutamic acid in inhibition assembly against copper corrosion in acidic solution

© 2015 Elsevier B.V. All rights reserved. A self-assembled multilayer (SAM) from sodium lauroyl sarcosinate (SLS) and glutamic acid (GLU) is formed on copper surface. Its inhibition ability against copper corrosion is examined by electrochemical analysis and weight loss test. In comparison to SAM formed by just SLS or GLU, a synergistic effect is observed when the coexistence of SLS and GLU in SAM. The SLS/GLU SAM has an acicular multilayer structure, and SAM prepared under the condition of 5 mM SLS and 1 mM GLU shows the best protection efficiency. PM6 calculation reveals that the synergistic effect stems from interactions between SLS, GLU and cupric ions.

Electrochemical and DFT studies of quinoline derivatives on corrosion inhibition of AA5052 aluminium alloy in NaCl solution

Two quinoline derivatives, 8-aminoquinoline (8-AQ) and 8-nitroquinoline (8-NQ), have been used as inhibitors to examine their corrosion protection effect on AA5052 aluminium alloy in 3% NaCl solution. The weight-loss and electrochemical measurement have indicated that 8-AQ and 8-NQ play as anodic inhibitor to retard the anodic electrochemical process. SEM/EDS analysis clearly shows that 8-AQ and 8-NQ form a protective film on the AA5052 alloy surface. Density functional theory (DFT) calculation confirmed the formation of strong hybridization between the p-orbital of reactive sites in the inhibitor molecules and the sp-orbital of the Al atom. 8-aminoquinoline and 8-nitroquinoline may be useful as effective corrosion inhibitors for aluminium alloys.

Synthesis and anti-corrosion performance of Adenine-L-Alanine ramification

In this paper, a new amino acid derivative, namely Adenine-L-Alanine ramification (ALAR) was synthesized and investigated as a green corrosion inhibitor for X80 pipeline steel in 0.1 mol/L hydrochloric acid solution using the weight loss, AC impedance, and polarization curve method. The structure of the derivative was characterized by IR and UV–vis spectrum. The weight loss and AC impedance found that the inhibition efficiency increased with the increase in concentration of the inhibitor but decreased with rise in temperature, the corrosion inhibition efficiency attains 91.26% in 8 × 10−2 g/L concentration at 30 °C. The polarization studies showed that the studied amino acid derivative can be used as a corrosion inhibitor. The surface of inhibited and uninhibited specimens was analyzed by scanning electron microscopy and the adsorption of the inhibitor on the mild steel surface obeys Langmuir adsorption isotherm. The quantum chemical descriptors such as the energy of highest occupied molecular orbital, energy of lowest unoccupied molecular orbital were calculated and the inhibition mechanism can be analyzed by the distribution of electrons. Analysis indicated that the inhibitor molecular and empty d orbital of metal forms the coordination bond, covers on the surface of metal, and prevents corrosion reaction.

Empowering primary care to tackle the obesity epidemic: the Counterweight Programme

Subjects: Obese patients (body mass index greater than or equal to30 kg/m2) or BMIgreater than or equal to28 kg/m2 with obesity-related comorbidities in 80 general practices.

Intervention: The model consists of four phases: (1) audit and project development, (2) practice training and support, (3) nurse-led patient intervention, and (4) evaluation. The intervention programme used evidence-based pathways, which included strategies to empower clinicians and patients. Weight Management Advisers who are specialist obesity dietitians facilitated programme implementation.

Main outcome measures: Proportion of practices trained and recruiting patients, and weight change at 12 months.

Results: By March 2004, 58 of the 62 (93.5%) intervention practices had been trained, 47 (75.8%) practices were active in implementing the model and 1549 patients had been recruited. At 12 months, 33% of patients achieved a clinically meaningful weight loss of 5% or more. A total of 49% of patients were classed as 'completers' in that they attended the requisite number of appointments in 3, 6 and 12 months. 'Completers' achieved more successful weight loss with 40% achieving a weight loss of 5% or more at 12 months.

Conclusion: The Counterweight programme provides a promising model to improve the management of obesity in primary care.

Evaluation of the Counterweight Programme for obesity management in primary care: a starting point for continuous improvement

Background Evaluation for obesity management in primary care is limited, and successful outcomes are from intensive clinical trials in hospital settings.

Aim To determine to what extent measures of success seen in intensive clinical trials can be achieved in routine primary care. Primary outcome measures were weight change and percentage of patients achieving ≤5% loss at 12 and 24 months.

Design of study Prospective evaluation of a new continuous improvement model for weight management in primary care.

Setting Primary care, UK.

Method Primary care practice nurses from 65 UK general practices delivered interventions to 1906 patients with body mass index (BMI) ≥30 kg/m2 or ≥28 kg/m2 with obesity-related comorbidities.

Results Mean baseline weight was 101.2 kg (BMI 37.1 kg/m2); 25% of patients had BMI ≥40 kg/m2 and 74% had ≥1 major obesity-related comorbidity. At final data capture 1419 patients were in the programme for ≥12 months, and 825 for ≥24 months. Mean weight change in those who attended and had data at 12 months (n = 642) was −3.0 kg (95% CI = −3.5 to −2.4 kg) and at 24 months (n = 357) was −2.3 kg (95% CI = −3.2 to −1.4 kg). Among attenders at specific time-points, 30.7% had maintained weight loss of ≥5% at 12 months, and 31.9% at 24 months. A total of 761 (54%) of all 1419 patients who had been enrolled in the programme for >12 months provided data at or beyond 12 months.

Conclusion This intervention achieves and maintains clinically valuable weight loss within routine primary care.
