Thanks to a coalescence of available scientific evidence and new regulatory possibilities, there is currently substantial opportunity for local innovation in addressing the public health problem of obesity. One promising example stems from a recent federal obesity-prevention initiative: the menu-labeling provisions of the Affordable Care Act (ACA), which require chain restaurants operating 20 or more locations to provide calorie information on their menus and menu boards, along with a statement addressing daily recommended caloric intake.
Este artigo objetiva compreender os fatores motivacionais que influenciam os indivíduos a doarem sangue, com a finalidade de subsidiar as ações de marketing social orientadas à captação de novos doadores. Com base em uma revisão teórica, um modelo de hipóteses foi elaborado, para análise de influências e interações de construtos na formação da predisposição das pessoas a serem doadores de sangue. Foi feito o levantamento de campo por meio de um questionário estruturado, junto a uma amostra de 346 pessoas. Para análise, foram usadas técnicas de análise descritiva, avaliação de consistência psicométrica e modelagem de equações estruturais com estimação por mínimos quadrados parciais. Como resultados, verificou-se principalmente que há uma influência negativa do medo e positiva do grupo de referência na predisposição dos sujeitos em doar sangue. Isso indicou que as ações de marketing social para a doação de sangue são mais eficientes em incentivar novos doadores se mantiverem foco nesses dois fatores.
Detecting hints to public health threats as early as possible is crucial to prevent harm from the population. However, many disease surveillance strategies rely upon data whose collection requires explicit reporting (data transmitted from hospitals, laboratories or physicians).
Collecting reports takes time so that the reaction time grows. Moreover, context information on individual cases is often lost in the collection process. This paper describes a system that tries to address these limitations by processing social media for identifying information on public health threats. The primary objective is to study the usefulness of the approach for supporting the monitoring of a population's health status.
The experiments show that the system provides information on health events identified in social media. Signals are mainly generated from Twitter messages posted by news agencies. Personal tweets, i.e. tweets from persons observing some symptoms, only play a minor role for signal generation given a limited volume of relevant messages. Relevant signals referring to real world outbreaks were generated by the system and monitored by epidemiologists for example during the European football championship.
But, the number of relevant signals among generated signals is still very small: The different experiments yielded a proportion between 5 and 20% of signals regarded as "relevant" by the users. Vaccination or education campaigns communicated via Twitter as well as use of medical terms in other contexts than for outbreak reporting led to the generation of irrelevant signals.
Conclusions: The aggregation of information into signals results in a reduction of monitoring effort compared to other existing systems. Against expectations, only few messages are of personal nature, reporting on personal symptoms. Instead, media reports are distributed over social media channels.
Despite the high percentage of irrelevant signals generated by the system, the users reported that the effort in monitoring aggregated information in form of signals is less demanding than monitoring huge social-media data streams manually. It remains for the future to develop strategies for reducing false alarms.
L’élaboration des guides alimentaires nationaux n’est peut-être pas toujours objective. Le chercheur Michel Lucas, lors d’une entrevue très éclairante sur le sujet, propose plutôt de baser notre alimentation sur «l’assiette santé».
It's also worth pointing out that charities such as Cancer Research UK and government-funded scientists are free to investigate promising treatments without a profit motive. And it's hard to understand why NHS doctors – who ...
Fitbit is the early dominant leader in the market for digital fitness trackers with nearly 40% of the market, according to new research Parks Associates announced today in advance of the firm's Connected Health Summit: Engaging Consumers, September 4-5 in San Diego, California.
De plus en plus de bracelets pour nous "coacher" sont proposés sur le marché. Cependant, il apparait qu’ils fournissent des résultats approximatifs et leurs mesures sont ainsi à relativiser. Est-il donc pertinent d’être connecté via bracelet ?
AbstractObjectives. Little is known about the use of social media as a tool for health communication. We used a mixed-methods design to examine communication about childhood obesity on Twitter.
Methods. NodeXL was used to collect tweets sent in June 2013 containing the hashtag #childhoodobesity. Tweets were coded for content; tweeters were classified by sector and health focus. Data were also collected on the network of follower connections among the tweeters. We used descriptive statistics and exponential random graph modeling to examine tweet content, characteristics of tweeters, and the composition and structure of the network of connections facilitating communication among tweeters.
Results. We collected 1110 tweets originating from 576 unique Twitter users. More individuals (65.6%) than organizations (32.9%) tweeted. More tweets focused on individual behavior than environment or policy. Few government and educational tweeters were in the network, but they were more likely than private individuals to be followed by others.
Conclusions. There is an opportunity to better disseminate evidence-based information to a broad audience through Twitter by increasing the presence of credible sources in the #childhoodobesity conversation and focusing the content of tweets on scientific evidence.
Twitter peut parfois se transformer en addiction compulsive. Beaucoup d’utilisateurs qui ont vu leur communauté croître doucement mais surement ont leurs yeux rivés régulièrement sur leurs chiffres. Combien de nouveaux followers et surtout combien de followers sont partis. C’est la règle sur Twitter on gagne des followers mais on en perd aussi au fil du temps et des hauts et des bas de sa timeline.
The shortage of blood donors and increased demand for blood is an important health issue. Finding ways to increase donor recruitment and retention is a priority and, thus, an important area for research. This article aims to better understand donors and nondonors on the basis of their social responsibility, susceptibility to interpersonal influence, involvement in and attitude towards the blood donation issue, and their aroused feelings. The data from 345 completed surveys were collected via a web-based, self-administered method. Mean differences were examined and the conceptual model was tested via structural equation modeling. The findings provide important clarification of donation and nondonation behavior.
A public forum on how social media could be used to connect the general public with health professionals and health policy makers, held in Vancouver in February, generated more than 1.5 million impressions on Twitter and trended strongly in Canada that night.
The session was co-organized by the BC Patient Safety & Quality Council (BCPSQC) and the UBC Faculty of Medicine eHealth Strategy (eHSO) Office. In addition to excellent participation of an in-person audience and an online webcast, the hashtag #sm4health achieved 1.59 million impressions on Twitter.
This enthusiastic online participation via Twitter signified the popularity of this topic and the public’s strong interest in exploring how this medium can contribute to quality of health communication and dialogues.
The public forum opened with BC Minister of Health Terry Lake, and the Executive Associate Dean of the Faculty of Medicine, Dr. David Snadden.
eHSO Director Dr. Kendall Ho welcomed the audience and BCPSQC Executive Director Christina Krause (pictured) gave a keynote presentation to share her personal story of why she became involved in patient safety and quality in healthcare.
In particular, the BCPSQC (@BCPSQC) has used social media to gather best practices and suggestions through World Sepsis Day by engaging global participation via Twitter.
Next on the agenda, Dr. Keith White, physician co-lead for the Shared Care Polypharmacy initiative of the Doctors of BC/MoH, offered a specific case example of how polypharmacy – giving more medications to a patient than clinically required or appropriate – can cause more harm than good.
Dr. White emphasized the need to be vigilant about the judicious use and reduction of medications, and the important role of patients and families as partners with healthcare professionals. A video produced by the Fraser Health Authority was shared on this subject.
Audience members were invited to share their thoughts on this topic, and were asked how social media could be optimally used to improve healthcare and reduce the risks of polypharmacy.
Live Tweets were displayed on the screen with participants from in the room and around the world. Ideas captured included:
• “What about social media reminders to the public/family members to schedule a “Med Review” with primary care MD or Pharmacy?”@NurseNerdy
• “Social media channels would be a great way to disseminate PSA, awareness campaign, etc. on polypharmacy to various audiences #sm4health.”@HelenJoey
• “Twitter or google chat w pharmacists to let families ask questions about #polypharmacy (thought needed around privacy though).”@Gndv
Twitter afforded the ability to capture a large amount of relevant data to inform future practice via crowdsourcing. The use of social media as part of the proceedings extended the discussion from the live audience to virtually anywhere.
Healthcare and Twitter are an excellent match. New studies can be shared instantly (think of Twitter’s 140-character limit as the ultimate book preview), YouTube videos can help spread important messages, blogs and microblogs can give insights and engage others through sharing of reflections.
We hope to leverage these media to reduce the average of 17 years it takes to use medical knowledge generated from medical research for routine and safe use in clinical practice, and improve the community members’ understanding of and participation in health care improvement – one tweet at a time.
During the forum, live polling was used to capture people’s thoughts and uses of social media in their daily lives. Twenty-five per cent of the in-house crowd indicated they use social media daily in their professional work, with many more using social media in their personal and social lives. A challenge and a benefit of social media rests in its ability to blend one’s personal and professional identities, a challenge that can be even more pronounced in healthcare.
Perhaps it was said best in this tweet: “Personal experience makes many of us want to improve the patient experience.”@TerryLakeMLA
Conclusions The ban on below cost selling, implemented in the England in May 2014, is estimated to have small effects on consumption and health harm. The previously announced policy of a minimum unit price, if set at expected levels between 40p and 50p per unit, is estimated to have an approximately 40-50 times greater effect.
The present meta-analysis suggests that consuming probiotics may improve BP by a modest degree, with a potentially greater effect when baseline BP is elevated, multiple species of probiotics are consumed, the duration of intervention is ≥8 weeks, or daily consumption dose is ≥1011 colony-forming units.
Millions of infants, children, and adolescents in the United States are not receiving the recommended preventive care, the Centers for Disease Control and Prevention (CDC) has reported.
The report1 focused on 11 preventive services: prenatal breastfeeding counseling, newborn hearing screening and follow-up, developmental screening, lead screening, vision screening, hypertension screening, dental care and preventive dental services, human papillomavirus vaccination, tobacco use screening and help in quitting, chlamydia screening, and reproductive health services. The report appeared as a supplement to the 12 September issue of the CDC’s
Despite warnings that drinking during pregnancy is unsafe, many women are still at risk for an alcohol-exposed pregnancy (AEP). This article describes the outcomes of a web-based, self-guided change intervention designed to lower the risk for AEPs in a community. A sample of 458 women, between the ages of 18 and 44 years and at risk for an AEP (i.e., any drinking in the past 30 days and not using reliable contraception), participated in the study. A total of 58% of the women enrolled in the self-guided change intervention were no longer at risk for an AEP at the 4-month follow-up. Sublevel analysis revealed that mail and online versions of the intervention were equally successful at reducing risk for an AEP. This study represents a successful implementation of a web-based, self-guided change intervention to reduce risk for an AEP, an intervention with community-wide reach due to the Internet platform
