1.  Long-term follow-up of a high- and a low-intensity smoking cessation intervention in a dental setting– a randomized trial 
BMC Public Health  2013;13:592.
Background
Achieving lifelong tobacco abstinence is an important public health goal. Most studies use 1-year follow-ups, but little is known about how good these are as proxies for long-term and life-long abstinence. Also, intervention intensity is an important issue for development of efficient and cost-effective cessation treatment protocols.
The study aims were to assess the long-term effectiveness of a high- and a low-intensity treatment (HIT and LIT) for smoking cessation and to analyze to what extent 12-month abstinence predicted long-term abstinence.
Methods
300 smokers attending dental or general health care were randomly assigned to HIT or LIT at the public dental clinic. Main outcome measures were self-reported point prevalence, continuous abstinence (≥6 months), and sustained abstinence. The study was a follow-up after 5–8 years of a previously performed 12-month follow-up, both by postal questionnaires.
Results
Response rate was 85% (n=241) of those still alive and living in Sweden. Abstinence rates were 8% higher in both programs at the long-term than at the 12-month follow-up. The difference of 7% between HIT and LIT had not change, being 31% vs. 24% for point prevalence and 26% vs. 19% for 6-month continuous abstinence, respectively. Significantly more participants in HIT (12%) than in LIT (5%) had been sustained abstinent (p=0.03). Logistic regression analyses showed that abstinence at 12-month follow-up was a strong predictor for abstinence at long-term follow-up.
Conclusions
Abstinence at 12-month follow-up is a good predictor for long-term abstinence. The difference in outcome between HIT and LIT for smoking cessation remains at least 5–8 years after the intervention.

2.  Drivers' and conductors' views on the causes and ways of preventing workplace violence in the road passenger transport sector in Maputo City, Mozambique 
BMC Public Health  2011;11:800.
Background
Workplace violence (WPV) is an occupational health hazard in both low and high income countries. To design WPV prevention programs, prior knowledge and understanding of conditions in the targeted population are essential. This study explores and describes the views of drivers and conductors on the causes of WPV and ways of preventing it in the road passenger transport sector in Maputo City, Mozambique.
Methods
The design was qualitative. Participants were purposefully selected from among transport workers identified as victims of WPV in an earlier quantitative study, and with six or more years of experience in the transport sector. Data were collected in semi-structured interviews. Seven open questions covered individual views on causes of WPV and its prevention, based on the interviewees' experiences of violence while on duty. Thirty-two transport professionals were interviewed. The data were analyzed by means of qualitative content analysis.
Results
The triggers and causes of violence included fare evasion, disputes over revenue owing to owners, alcohol abuse, overcrowded vehicles, and unfair competition for passengers. Failures to meet passenger expectations, e.g. by-passing parts of a bus route or missing stops, were also important. There was disrespect on the part of transport workers, e.g. being rude to passengers and jumping of queues at taxi ranks, and there were also robberies. Proposals for prevention included: training for workers on conflict resolution, and for employers on passenger-transport administration; and, promoting learning among passengers and workers on how to behave when traveling collectively. Regarding control and supervision, there were expressed needs for the recording of mileage, and for the sanctioning of workers who transgress queuing rules at taxi ranks. The police or supervisors should prevent drunken passengers from getting into vehicles, and drivers should refuse to go to dangerous, secluded neighborhoods. Finally, there is a need for an institution to judge alleged cases of employees not handing over demanded revenues to their employer.
Conclusions
The causes of WPV lie in problems regarding money, behavior, environment, organization and crime. Suggestions for prevention include education, control to avoid critical situations, and a judicial system to assess malpractices. Further research in the road passenger transport sector in Maputo City, Mozambique and similar settings is warranted.

3.  The relevance of WHO injury surveillance guidelines for evaluation: learning from the aboriginal community-centered injury surveillance system (ACCISS) and two institution-based systems 
BMC Public Health  2011;11:744.
Background
Over the past three decades, the capacity to develop and implement injury surveillance systems (ISS) has grown worldwide and is reflected by the diversity of data gathering environments in which ISS operate. The capacity to evaluate ISS, however, is less advanced and existing evaluation guidelines are ambiguous. Furthermore, the applied relevance of these guidelines to evaluate ISS operating in various settings is unclear. The aim of this paper was to examine how the World Health Organization (WHO) injury surveillance guidelines have been applied to evaluate systems operating in three different contexts.
Methods
The attributes of a good surveillance system as well as instructions for conducting evaluations, outlined in the WHO injury surveillance guidelines, were used to develop an analytical framework. Using this framework, a comparative analysis of the application of the guidelines was conducted using; the Aboriginal Community-Centered Injury Surveillance System (ACCISS) from Canada, the Shantou-Emergency Department Injury Surveillance Project (S-EDISP) from China, and the Yorkhill-Canadian Hospitals Injury Reporting and Prevention Program (Y-CHIRPP) imported from Canada and implemented in Scotland.
Results
The WHO guidelines provide only a basic platform for evaluation. The guidelines over emphasize epidemiologic attributes and methods and under emphasize public health and injury prevention perspectives requiring adaptation for context-based relevance. Evaluation elements related to the dissemination and use of knowledge, acceptability, and the sustainability of ISS are notably inadequate. From a public health perspective, alternative reference points are required for re-conceptualizing evaluation paradigms. This paper offers an ISS evaluation template that considers how the WHO guidelines could be adapted and applied.
Conclusions
Findings suggest that attributes of a good surveillance system, when used as evaluation metrics, cannot be weighted equally across ISS. In addition, the attribute of acceptability likely holds more relevance than previously recognized and should be viewed as a critical underpinning attribute of ISS. Context-oriented evaluations sensitive to distinct operational environments are more likely to address knowledge gaps related to; understanding links between the production of injury data and its use, and the effectiveness, impact, and sustainability of ISS. Current frameworks are predisposed to disassociating epidemiologic approaches from subjective factors and social processes.

4.  Health promotion at local level: a case study of content, organization and development in four Swedish municipalities 
BMC Public Health  2010;10:455.
Background
Several health determinants are related to local conditions and prerequisites at community level. For this reason, strengthening community action has been one of five strategies implemented in health promotion since the end of the 1980s. Such action includes setting priorities, making decisions, planning strategies, and implementing them to achieve better health. The aim of this paper is to obtain a deeper understanding of content, organization and processes in the development of local health promotion.
Methods
A qualitative multiple case study of four Swedish municipalities. The cases were analyzed in accordance with the principles of cross-case study analysis, and a content analysis of documents and interviews was conducted in two steps. First, a manifest content analysis was performed to identify present and former actors and measures. Thereafter, a latent content analysis was performed to investigate structures and processes in local contexts.
Results
The results of the inductive content analysis showed development of local health promotion in three phases: initiation, action, and achievement. Strengthening factors were local actors, health statistics and events. Hindering factors were lack of resources and vague objectives. External factors, e.g. national policies, were not perceived as prominent influencing factors. Media reports were regarded as having had an influence, but only to some extent. The content of local health promotion has developed from ad-hoc lifestyle and behaviour-related actions into structural, intersectoral actions related to determinants of health.
Conclusions
The municipalities have organized and developed their health promotion targets, actions and priorities on the basis of local needs and prerequisites. The three phases in the identified health promotion processes were experienced and documented as being subject to greater influence from internal rather than external strengthening and hindering factors in their local contexts.

5.  Comparison of a high and a low intensity smoking cessation intervention in a dentistry setting in Sweden – a randomized trial 
BMC Public Health  2009;9:121.
Background
Tobacco is still the number one life style risk factor for ill health and premature death and also one of the major contributors to oral problems and diseases. Dentistry may be a potential setting for several aspects of clinical public health interventions and there is a growing interest in several countries to develop tobacco cessation support in dentistry setting. The aim of the present study was to assess the relative effectiveness of a high intensity intervention compared with a low intensity intervention for smoking cessation support in a dental clinic setting.
Methods
300 smokers attending dental or general health care were randomly assigned to two arms and referred to the local dental clinic for smoking cessation support. One arm received support with low intensity treatment (LIT), whereas the other group was assigned to high intensity treatment (HIT) support. The main outcome measures included self-reported point prevalence and continuous abstinence (≥ 183 days) at the 12-month follow-up.
Results
Follow-up questionnaires were returned from 86% of the participants. People in the HIT-arm were twice as likely to report continuous abstinence compared with the LIT-arm (18% vs. 9%, p = 0.02). There was a difference (not significant) between the arms in point prevalence abstinence in favour of the HIT-protocol (23% vs. 16%). However, point prevalence cessation rates in the LIT-arm reporting additional support were relatively high (23%) compared with available data assessing abstinence in smokers trying to quit without professional support.
Conclusion
Screening for willingness to quit smoking within the health care system and offering smoking cessation support within dentistry may be an effective model for smoking cessation support in Sweden. The LIT approach is less expensive and time consuming and may be appropriate as a first treatment option, but should be integrated with other forms of available support in the community. The more extensive and expensive HIT-protocol should be offered to those who are unable to quit with the LIT approach in combination with other support.

6.  Non-pharmaceutical prevention of hip fractures – a cost-effectiveness analysis of a community-based elderly safety promotion program in Sweden 
Background
Elderly injuries are a recognized public health concern and are due to two factors; osteoporosis and accidental falls. Several osteoporosis pharmaceuticals are considered cost-effective, but intervention programs aiming at preventing falls should also be subjected to economic evaluations. This study presents a cost-effectiveness analysis of a community-based elderly safety promotion program.
Methods
A five-year elderly safety promotion program combining environmental structural changes with individually based measures was implemented in a community in the metropolitan area of Stockholm, Sweden. The community had around 5,500 inhabitants aged 65+ years and a first hip fracture incidence of 10.7 per 1,000 in pre-intervention years 1990–1995. The intervention outcome was measured as avoided hip fractures, obtained from a register-based quasi-experimental longitudinal analysis with several control areas. The long-term consequences in societal costs and health effects due to the avoided hip fractures, conservatively assumed to be avoided for one year, were estimated with a Markov model based on Swedish data. The analysis holds the societal perspective and conforms to recommendations for pharmaceutical cost-effectiveness analyses.
Results
Total societal intervention costs amounted to 6.45 million SEK (in Swedish krona 2004; 1 Euro = 9.13 SEK). The number of avoided hip fractures during the six-year post-intervention period was estimated to 14 (0.44 per 1,000 person-years). The Markov model estimated a difference in societal costs between an individual that experiences a first year hip fracture and an individual that avoids a first year hip fracture ranging from 280,000 to 550,000 SEK, and between 1.1 and 3.2 QALYs (quality-adjusted life-years, discounted 3%), for males and females aged 65–79 years and 80+ years. The cost-effectiveness analysis resulted in zero net costs and a gain of 35 QALYs, and the do-nothing alternative was thus dominated.
Conclusion
The community-based elderly safety promotion program aiming at preventing accidental falls seems as cost-effective as osteoporosis pharmaceuticals.
