Community-based cardiovascular disease prevention programmes and cardiovascular risk factors: a systematic review and meta-analysis. Public Health 2021; 200:59-70. [PMID: 34700187 DOI: 10.1016/j.puhe.2021.09.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 08/16/2021] [Accepted: 09/02/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVES This study aimed to summarise the effect of community-based intervention programmes on the prevention of cardiovascular disease (CVD) by reducing cardiometabolic risk factors. STUDY DESIGN This was a systematic review and meta-analysis. METHODS A systematic search in the PubMed database and screening of reference lists aimed to identify community-based CVD prevention programmes from inception up to April 2020. The mean differences and standard deviations for CVD risk factors, including blood pressure, lipid profile, blood glucose and body weight indices, were extracted and pooled using a random effects model. RESULTS Screening of 11,889 titles/abstracts and full texts resulted in 48 studies being included in this review. The meta-analysis showed that community-based programmes have led to considerable decreases in systolic blood pressure (weighted mean difference [WMD] = -2.90 mm Hg, 95% confidence interval [95% CI]: -3.63, -2.16), diastolic blood pressure (WMD = -2.21 mm Hg, 95% CI: -3.12, -1.29), serum levels of low-density lipoprotein cholesterol (LDL-C; WMD = -8.88 mg/dl, 95% CI: -12.84, -4.92), triglycerides (WMD = -8.40 mg/dl, 95% CI: -12.10, -4.70), total cholesterol (WMD = -2.96 mg/dl, 95% CI: -3.10, -2.81) and fasting blood glucose (WMD = -2.06 mg/dl, 95% CI: -3.02, -1.10). A moderate decrease in body weight was also found with community-based CVD prevention programmes. However, community-based CVD prevention programmes were not associated with any significant changes in serum levels of high-density lipoprotein. CONCLUSIONS The present study indicates that community-based strategies have successfully led to an improvement in CVD risk factors, particularly by reducing blood pressure, serum levels of LDL-C and triglycerides, obesity indices and blood glucose. The impact of these programmes on CVD is modified by the type of intervention and by different cultural and physical environments.

Abstract
This study aims to assess the effects of a community-based lifestyle intervention program on the incidence of type 2 diabetes (T2D). For this purpose, three communities in Tehran were chosen; one community received a face-to-face educational session embedded in a long-term community-wide lifestyle intervention aimed at supporting lifestyle changes. We followed up 9,204 participants (control: 5,739, intervention: 3,465) triennially from 1999 to 2015 (Waves 1-5). After a median follow-up of 3.5 years (wave 2), the risk of T2D was 30% lower in the intervention community as compared with two control communities by (Hazard-ratio: 0.70 [95% CI 0.53; 0.91]); however, the difference was not statistically significant in the following waves. After a median follow-up of 11.9 years (wave 5), there was a non-significant 6% reduction in the incidence of T2D in the intervention group as compared to the control group (Hazard-ratio: 0.94 [0.81, 1.08]). Moreover, after 11.9 years of follow-up, the intervention significantly improved the diet quality measured by the Dietary Approaches to Stop Hypertension concordance (DASH) score. Mean difference in DASH score in the intervention group versus control group was 0.2 [95% CI 0.1; 0.3]. In conclusion, the intervention prevented T2D by 30% in the short-term (3.5 years) but not long-term; however, effects on improvement of the diet maintained in the long-term.Registration: This study is registered at IRCT, a WHO primary registry ( https://irct.ir ).

Abstract
IMPORTANCE It is unclear whether effective population-wide interventions that reduce risk factors and improve health result in sustained benefits to a community's health. If benefits do persist after a program is ended, interventions could be brief rather than maintained long term. OBJECTIVE To measure mortality and smoking rates in a rural community over decades before, during, and after prevention program reductions. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study compared smoking and mortality rates in a rural Maine county with other Maine counties over time by 5-year intervals. Multiple changes occurred between 2001 and 2015 in the physiological and behavioral risk factor reduction programs offered in the county. They included reductions in leadership, staff, institutional resources, data monitoring, and the programs themselves. Data were analyzed from May 2018 to March 2019. INTERVENTION Previous multifaceted interventions and outcome monitoring were withdrawn or diminished in the past decade. MAIN OUTCOMES AND MEASURES Smoking and age-adjusted mortality rates vs household income. RESULTS Reduced mortality rates in Franklin County in 1986 to 2005 reverted to those predicted by household incomes, relative to other Maine counties, by 2006 to 2015 (1986-1990 T score = -2.86 [P = .01] and 2001-2005 T score = -3.00 [P = .01] to 2006 to 2010 T score = -0.43 [P = .67] and 2011-2015 T score = -0.72 [P = .48]). Analysis of County Health Rankings data from 2010 to 2018 also showed that Franklin County's outcomes have reverted to no better than predicted by socioeconomic status. The county's T scores increased from -3.62 (P = .003) in 2010 to -0.41 (P = .69) in 2015 to 0.13 (P = .90) in 2018. Statewide association of income with mortality by analyses of variance showed that the R2 values have increased from the decades preceding 2000 (1976-1980, R2 = 0.21; P = .08; 1986-1990, R2 = 0.32; P = .02) to 2006 to 2010 (R2 = 0.73; P < .001) and 2011 to 2015 (R2 = 0.70; P < .001). CONCLUSIONS AND RELEVANCE This study suggests that gains associated with population health interventions may be lost when the interventions are reduced. Adjusting outcome measures for socioeconomic status may allow quicker and more sensitive monitoring of intervention adequacy and success. The increasing trend of age-adjusted mortality in Maine and nationally to correlate inversely with incomes may warrant further community interventions, especially for poorer populations.

Different outcomes for different interventions with different focus!— A cross-country comparison of community interventions in rural Swedish and US populations. Scand J Public Health 2017.

Abstract
Objectives: There is a need among healthcare providers to acquire more knowledge about small-scale and low budget community intervention programmes. This paper compares risk factor outcomes in Swedish and US intervention programmes for the prevention of cardiovascular disease (CVD). The aim was to explore how different intervention programme profiles affect outcome. Methods: Using a quasi-experimental design, trends in risk factors and estimated CVD risk in two intervention areas (Norsjö, Sweden and Otsego- Schoharie County, New York state) are compared with those in reference areas (Northern Sweden region and Herkimer County, New York state) using serial cross-sectional studies and panel studies. Results: The programmes were able to achieve significant changes in CVD risk factors that the local communities recognized as major concerns: changing eating habits in the Swedish population and reducing smoking in the US population. For the Swedish cross-sectional follow-up study cholesterol reduction was 12%, compared to 5% in the reference population ( p for trend differences < 0.000) . The significantly higher estimated CVD risk (as assessed by risk scores) at baseline in the intervention population was below that of the Swedish reference population after 5 years of intervention. The Swedish panel study provided the same results. In the US, both the serial cross-sectional and panel studies showed a >10% decline in smoking prevalence in the intervention population, while it increased slightly in the reference population. When pooling the serial cross-sectional studies the estimated risk reduction (using the Framingham risk equation) was significantly greater in the intervention populations compared to the reference populations. Conclusions: The overall pattern of risk reduction is consistent and suggests that the two different models of rural county intervention can contribute to significant risk reduction. The Swedish programme had its greatest effect on reduction of serum cholesterol levels whereas the US programme had its greatest effect on smoking prevention and cessation. These outcomes are consistent with programmatic emphases. Socially less privileged groups in these rural areas benefited as much or more from the interventions as those with greater social resources.

Effectiveness of interventions to promote physical activity and/or decrease sedentary behaviour among rural adults: a systematic review and meta-analysis. Obes Rev 2017; 18:727-741. [PMID: 28401687 DOI: 10.1111/obr.12533] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2016] [Revised: 01/25/2017] [Accepted: 02/12/2017] [Indexed: 11/28/2022]
Abstract
Physical inactivity and overweight and obesity are more prevalent among rural than urban populations. This study aimed to review published evidence of the effectiveness of interventions to increase physical activity (PA) and/or decrease sedentary behaviour (SB) among rural adults and to identify factors associated with effectiveness. Seven electronic databases were searched for controlled trials of a PA or SB intervention. Meta-analysis was conducted using random effects models and meta-regression. Thirteen studies were included in the qualitative synthesis (n = 4,848 participants) and 12 in the meta-analysis (n = 4,820). All studies were interventions to increase PA. Overall, there was no effect on PA (standardized mean difference [SMD] 0.11; 95% confidence interval [CI] -0.04, 0.25) or SB (SMD 0.07; 95% CI -0.33, 0.20). In PA subgroup analyses, studies employing objective outcome measures demonstrated effects in favour of the intervention (SMD 0.65, 95% CI 0.30, 1.00), while those using self-reported measures did not (SMD 0.00; 95% CI -0.11, 0.10). This review highlights significant gaps in our understanding of how best to promote PA and reduce SB among rural adults. Future studies should use objective measures of PA as study outcomes. The absence of interventions to decrease SB is of concern, with immediate action required to address this large knowledge gap.

Abstract
The aim of this study was to identify and reflect on the methods employed by studies focusing on intervention programs for the primordial and primary prevention of cardiovascular diseases. The PubMed, EMBASE, SciVerse Hub-Scopus, and Cochrane Library electronic databases were searched using the terms 'effectiveness AND primary prevention AND risk factors AND cardiovascular diseases' for systematic reviews, meta-analyses, randomized clinical trials, and controlled clinical trials in the English language. A descriptive analysis of the employed strategies, theories, frameworks, applied activities, and measurement of the variables was conducted. Nineteen primary studies were analyzed. Heterogeneity was observed in the outcome evaluations, not only in the selected domains but also in the indicators used to measure the variables. There was also a predominance of repeated cross-sectional survey design, differences in community settings, and variability related to the randomization unit when randomization was implemented as part of the sample selection criteria; furthermore, particularities related to measures, limitations, and confounding factors were observed. The employed strategies, including their advantages and limitations, and the employed theories and frameworks are discussed, and risk communication, as the key element of the interventions, is emphasized. A methodological process of selecting and presenting the information to be communicated is recommended, and a systematic theoretical perspective to guide the communication of information is advised. The risk assessment concept, its essential elements, and the relevant role of risk perception are highlighted. It is fundamental for communication that statements targeting other people's understanding be prepared using systematic data.

Abstract
INTRODUCTION Although cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM) prevention programmes have been effective in urban residents, their effectiveness in non-urban settings, where cardio-metabolic risk is typically elevated, is unknown. We systematically reviewed the effectiveness of primary prevention programmes aimed at reducing risk factors for CVD/T2DM, including blood pressure, body mass index (BMI), blood lipid and glucose, diet, lifestyle, and knowledge in adults residing in non-urban areas. METHODS Twenty-five manuscripts, globally, from 1990 were selected for review (seven included in the meta-analyses) and classified according to: 1) study design (randomised controlled trial [RCT] or pre-/post-intervention); 2) intervention duration (short [<12months] or long term [≥12months]), and; 3) programme type (community-based programmes or non-community-based programmes). RESULTS Multiple strategies within interventions focusing on health behaviour change effectively reduced cardio-metabolic risk in non-urban individuals. Pre-/post-test design studies showed more favourable improvements generally, while RCTs showed greater improvements in physical activity and disease and risk knowledge. Short-term programmes were more effective than long-term programmes and in pre-/post-test designs reduced systolic blood pressure by 4.02mmHg (95% CI -6.25 to -1.79) versus 3.63mmHg (95% CI -7.34 to 0.08) in long-term programmes. Community-based programmes achieved good results for most risk factors except BMI and (glycated haemoglobin) HbA1c. CONCLUSION The setting for applying cardio-metabolic prevention programmes is important given its likelihood to influence programme efficacy. Further investigation is needed to elucidate the individual determinants of cardio-metabolic risk in non-urban populations and in contrast to urban populations.

Abstract
INTRODUCTION Rural US residents smoke at higher rates than urban or suburban residents. We report results from a community-based smoking cessation intervention in Appalachian Kentucky. STUDY DESIGN Single-blind, group-randomized trial with outcome measurements at baseline, 17 weeks and 43 weeks. SETTING/PARTICIPANTS This faith-placed CBPR project was located in six counties of rural Appalachian Kentucky. A total of 590 individual participants clustered in 28 churches were enrolled in the study. INTERVENTION Local lay health advisors delivered the 12-week Cooper/Clayton Method to Stop Smoking program, leveraging sociocultural factors to improve the cultural salience of the program for Appalachian smokers. Participants met with an interventionist for one 90 min group session once per week incorporating didactic information, group discussion, and nicotine replacement therapy. MAIN OUTCOME MEASURES The primary outcome was self-reported smoking status. Secondary outcomes included Fagerström nicotine dependence, self-efficacy, and decisional balance. RESULTS With post-intervention data from 92% of participants, those in intervention group churches (N = 383) had 13.6 times higher odds of reporting quitting smoking one month post-intervention than participants in attention control group churches (N = 154, p < 0.0001). In addition, although only 3.2% of attention control group participants reported quitting during the control period, 15.4% of attention control participants reported quitting smoking after receiving the intervention. A significant dose effect of the 12-session Cooper/Clayton Method was detected: for each additional session completed, the odds of quitting smoking increased by 26%. CONCLUSIONS The Cooper/Clayton Method, delivered in rural Appalachian churches by lay health advisors, has strong potential to reduce smoking rates and improve individuals' health.

Abstract
A meta-analytic review was undertaken to examine the effects of mass communication campaigns on changes in behavior, knowledge, and self-efficacy in the general public. A review of the academic literature was undertaken and identified 1,638 articles from 1966 through 2012. Using strict inclusion criteria, we included 63 studies for coding and analyses. Results from these efforts indicated that campaigns produced positive effects in behavior change (r = .05, k = 61) and knowledge (r = .10, k = 26) but failed to produce significant increases in self-efficacy (r = .02, k = 14). Several moderators (e.g., health topic, the theory underlying the campaign) were examined in relation to campaign principles that are prescribed to increase campaign effects. The major findings are reviewed, and the implications for future campaign design are discussed.

SEARCH METHODS We searched the Cochrane Public Health Group Segment of the Cochrane Register of Studies,The Cochrane Library, MEDLINE, MEDLINE in Process, EMBASE, CINAHL, LILACS, PsycINFO, ASSIA, the British Nursing Index, Chinese CNKI databases, EPPI Centre (DoPHER, TRoPHI), ERIC, HMIC, Sociological Abstracts, SPORT Discus, Transport Database and Web of Science (Science Citation Index, Social Sciences Citation Index, Conference Proceedings Citation Index). We also scanned websites of the EU Platform on Diet, Physical Activity and Health; Health-Evidence.org; the International Union for Health Promotion and Education; the NIHR Coordinating Centre for Health Technology (NCCHTA); the US Centre for Disease Control and Prevention (CDC) and NICE and SIGN guidelines. Reference lists of all relevant systematic reviews, guidelines and primary studies were searched and we contacted experts in the field. The searches were updated to 16 January 2014, unrestricted by language or publication status. SELECTION CRITERIA Cluster randomised controlled trials, randomised controlled trials, quasi-experimental designs which used a control population for comparison, interrupted time-series studies, and prospective controlled cohort studies were included. Only studies with a minimum six-month follow up from the start of the intervention to measurement of outcomes were included. Community wide interventions had to comprise at least two broad strategies aimed at physical activity for the whole population. Studies which randomised individuals from the same community were excluded. DATA COLLECTION AND ANALYSIS At least two review authors independently extracted the data and assessed the risk of bias. Each study was assessed for the setting, the number of included components and their intensity. The primary outcome measures were grouped according to whether they were dichotomous (per cent physically active, per cent physically active during leisure time, and per cent physically inactive) or continuous (leisure time physical activity time (time spent)), walking (time spent), energy expenditure (as metabolic equivalents or METS)). For dichotomous measures we calculated the unadjusted and adjusted risk difference, and the unadjusted and adjusted relative risk. For continuous measures we calculated percentage change from baseline, unadjusted and adjusted. MAIN RESULTS After the selection process had been completed, 33 studies were included. A total of 267 communities were included in the review (populations between 500 and 1.9 million). Of the included studies, 25 were set in high income countries and eight were in low income countries. The interventions varied by the number of strategies included and their intensity. Almost all of the interventions included a component of building partnerships with local governments or non-governmental organisations (NGOs) (29 studies). None of the studies provided results by socio-economic disadvantage or other markers of equity. However, of those included studies undertaken in high income countries, 14 studies were described as being provided to deprived, disadvantaged or low socio-economic communities. Nineteen studies were identified as having a high risk of bias, 10 studies were unclear, and four studies had a low risk of bias. Selection bias was a major concern with these studies, with only five studies using randomisation to allocate communities. Four studies were judged as being at low risk of selection bias although 19 studies were considered to have an unclear risk of bias. Twelve studies had a high risk of detection bias, 13 an unclear risk and four a low risk of bias. Generally, the better designed studies showed no improvement in the primary outcome measure of physical activity at a population level.All four of the newly included, and judged to be at low risk of bias, studies (conducted in Japan, United Kingdom and USA) used randomisation to allocate the intervention to the communities. Three studies used a cluster randomised design and one study used a stepped wedge design. The approach to measuring the primary outcome of physical activity was better in these four studies than in many of the earlier studies. One study obtained objective population representative measurements of physical activity by accelerometers, while the remaining three low-risk studies used validated self-reported measures. The study using accelerometry, conducted in low income, high crime communities of USA, emphasised social marketing, partnership with police and environmental improvements. No change in the seven-day average daily minutes of moderate to vigorous physical activity was observed during the two years of operation. Some program level effect was observed with more people walking in the intervention community, however this result was not evident in the whole community. Similarly, the two studies conducted in the United Kingdom (one in rural villages and the other in urban London; both using communication, partnership and environmental strategies) found no improvement in the mean levels of energy expenditure per person per week, measured from one to four years from baseline. None of the three low risk studies reporting a dichotomous outcome of physical activity found improvements associated with the intervention.Overall, there was a noticeable absence of reporting of benefit in physical activity for community wide interventions in the included studies. However, as a group, the interventions undertaken in China appeared to have the greatest possibility of success with high participation rates reported. Reporting bias was evident with two studies failing to report physical activity measured at follow up. No adverse events were reported.The data pertaining to cost and sustainability of the interventions were limited and varied. AUTHORS' CONCLUSIONS Although numerous studies have been undertaken, there is a noticeable inconsistency of the findings in the available studies and this is confounded by serious methodological issues within the included studies. The body of evidence in this review does not support the hypothesis that the multi-component community wide interventions studied effectively increased physical activity for the population, although some studies with environmental components observed more people walking.

Abstract
BACKGROUND It is challenging to assist people to attend to risk factors for coronary artery disease (CAD). There is potential for cultural elements associated with place of residence (i.e., urban- or rural-living) to have an effect on peoples' decision-making about managing CAD risk. AIM To better understand patient's decision-making processes regarding having a heart-healthy diet and engaging in regular physical activity (major CAD risk factors), and the potential influence of urban- or rural-living. METHODS Based on a previous series of qualitative interviews with 42 cardiac patients (21 urban-living, 21 rural-living), hierarchical decision-models regarding eating a heart-healthy diet and engaging in regular physical activity were developed, and a survey based on the decision-models generated. The models were then tested for 'fit' with another group of 42 cardiac patients, and were revised to make them more parsimonious. The final models were tested with a novel group of 647 CAD patients from Alberta, Canada (327 urban-living, 320 rural-living). The primary analysis was focused on determining the extent to which patients completing the survey fell in the correct behavioral group. Thereafter individual nodes were examined to determine decision-making constructs that were different between urban- and rural-living patients. RESULTS When tested, the models had overall accuracy of 93.5% for diet and 97.5% for physical activity. The most salient model nodes that led to differing behavioral outcomes reflected these constructs: perception of control over health; time, effort, or competing priorities; receipt of appropriate information; and appeal of the activity. CONCLUSIONS This information is potentially useful to assist healthcare providers to: (1) understand patients' decisions regarding their cardiac risk factor modification behavior, and (2) better direct conversations about risk factor modification and educational activities.

Reference lists of all relevant systematic reviews, guidelines and primary studies were followed up. We contacted experts in the field from the National Obesity Observatory Oxford, Oxford University; Queensland Health, Queensland University of Technology, the University of Central Queensland; the University of Tennessee and Washington University; and handsearched six relevant journals. The searches were last updated to the end of November 2009 and were not restricted by language or publication status. SELECTION CRITERIA Cluster randomised controlled trials, randomised controlled trials (RCT), quasi-experimental designs which used a control population for comparison, interrupted time-series (ITS) studies, and prospective controlled cohort studies (PCCS) were included.

No studies were judged as being at low risk of selection bias although 16 studies were considered to have an unclear risk of bias. Eleven studies had a high risk of detection bias, 10 with an unclear risk and four with no risk. Assessment of detection bias included an assessment of the validity of the measurement tools and quality of outcome measures. The effects reported were inconsistent across the studies and the measures. Some of the better designed studies showed no improvement in measures of physical activity. Publication bias was evident.

The body of evidence in this review does not support the hypothesis that multi-component community wide interventions effectively increase population levels of physical activity. There is a clear need for well-designed intervention studies and such studies should focus on the quality of the measurement of physical activity, the frequency of measurement and the allocation to intervention and control communities.

Abstract
In this systematic review, the authors aimed to assess the effectiveness of community programs for prevention of cardiovascular disease (CVD). They searched numerous electronic databases (CDSR, DARE, HTA, EED, and CENTRAL via the Cochrane Library, MEDLINE, MEDLINE In Process, EMBASE, CINAHL, PsycINFO, HMIC, and ASSIA) and relevant Web sites from January 1970 to mid-July 2008. Controlled studies of community programs for the primary prevention of CVD were included. Net changes in CVD risk factors were used to generate an overall index for net change in 10-year CVD risk. The authors identified 36 relevant community programs that took place between 1970 and 2008. These programs were multifaceted interventions employing combinations of media, screening, and counseling activities and environmental changes and were primarily evaluated using controlled before-after studies. In 7 studies, investigators reported changes in CVD/total mortality rates, and in 5 they reported net changes. In all cases, these net changes were positive but were largely nonsignificant. In 22 studies, investigators reported changes in physiologic CVD risk factors, and there was a positive trend in the calculated CVD risk score. The average net reduction in 10-year CVD risk was 0.65%. Community programs for CVD prevention appear to have generally achieved favorable changes in overall CVD risk and, with adaptation to current circumstances, deserve continued consideration as possible approaches to preventing CVD.

Abstract
This article reviews the most common nonpharmacologic approaches used to support smoking cessation and, where possible, provides estimates of their efficacy in controlled clinical trials. Virtually all of the approaches that have been systematically evaluated to date have demonstrated modest efficacy in increasing quit rates. A cornerstone of effective treatment is tobacco dependence counseling, for which there is a dose-response relation between the intensity of counseling (total minutes of contact) and its effectiveness. New approaches in which treatment is tailored to individual patient characteristics appear promising for the future but require further study. Also, new technologies that permit delivery of smoking interventions to a wider range of patients could have a significant impact on reducing smoking prevalence worldwide in the future. Overall, the clinical literature strongly endorses combining nonpharmacologic interventions with pharmacotherapy to optimize support for smokers who are trying to quit.

Abstract
The study objective was to evaluate the incidence of overweight and obesity in two rural areas of Sweden and the U.S. Previously collected data were used from 1990 to 1999 Multinational Monitoring of Trends and Determinants in Cardiovascular Disease (MONICA) studies in northern Sweden. Health censuses of adults in Otsego County, New York were collected in 1989 and 1999. Adults aged 25-64 year in 1989 with reports from both surveys were included. The 10-year change in body mass index (BMI), overweight (BMI 25-29.9 kg/m2) and obesity (BMI>or=30) were obtained from panel studies. Incidences of overweight and obesity were calculated and compared between countries. The 10-year incidence of obesity was 120/1000 in Sweden and 173/1000 in the U.S. (p<0.001 for difference between countries). In 1999, prevalence of obesity rose to 18.4% (Sweden) and 32.3% (U.S.). Cumulative distribution curves show that the BMI distribution in Sweden during 1999 is nearly identical to the U.S. during 1989. The obese proportions of these rural populations increased from 1989 to 1999. Sweden's obesity epidemic has a progression similar to that of the U.S., implying that by 2009, the prevalence of obesity in rural northern Sweden may mimic that present in rural New York during 1999. Attention should be paid to the increased obesity rates in rural areas.

Abstract
The aim of this paper is to review evidence published since 1997 on the effectiveness of mass media, print, telephone and website-delivered physical activity (PA) interventions. For mass media, there is consistent evidence for impacts on recall of campaign tag lines and message content and modest evidence of short-term impacts on behaviour in some population subgroups. Print-based delivery of programs can have a modest impact on behaviour; research is needed on supplementary strategies to support print programs. Although there is a strong case for the potential of telephone and Internet delivered interventions, there is as yet little evidence that they can be effective. All of these 'mediated' approaches to PA program delivery are likely to be important elements of future public health interventions. The body of evidence for their effectiveness in changing behaviour is currently modest, however, and it is clear that these approaches have not yet been fully developed and evaluated. Combinations of different media and mutually supportive, integrated strategies are likely to be more effective and need to be developed and evaluated systematically, building on the current research evidence base.

Abstract
BACKGROUND Since smoking behaviour is determined by social context, the best way to reduce the prevalence of smoking may be to use community-wide programmes which use multiple channels to provide reinforcement, support and norms for not smoking. OBJECTIVES To assess the effectiveness of community interventions for reducing the prevalence of smoking. SEARCH STRATEGY We searched the Cochrane Tobacco Addiction Group specialised register, MEDLINE (1966-August 2001) and EMBASE (1980-August 2001) and reference lists of articles. SELECTION CRITERIA Controlled trials of community interventions for reducing smoking prevalence in adult smokers. The primary outcome was smoking behaviour. DATA COLLECTION AND ANALYSIS Data were extracted by one person and checked by a second. MAIN RESULTS Thirty two studies were included, of which seventeen included only one intervention and one comparison community. Only four studies used random assignment of communities to either the intervention or comparison group. The population size of the communities ranged from a few thousand to over 100,000 people. Change in smoking prevalence was measured using cross-sectional follow-up data in 27 studies. The estimated net decline ranged from -1.0% to 3.0% for men and women combined (10 studies). For women, the decline ranged from -0.2% to + 3.5% per year (n=11), and for men the decline ranged from -0.4% to +1.6% per year (n=12). Cigarette consumption and quit rates were only reported in a small number of studies. The two most rigorous studies showed limited evidence of an effect on prevalence. In the US COMMIT study there was no differential decline in prevalence between intervention and control communities, and there was no significant difference in the quit rates of heavier smokers who were the target intervention group. In the Australian CART study there was a significantly greater quit rate for men but not women. REVIEWER'S CONCLUSIONS The failure of the largest and best conducted studies to detect an effect on prevalence of smoking is disappointing. A community approach will remain an important part of health promotion activities, but designers of future programmes will need to take account of this limited effect in determining the scale of projects and the resources devoted to them.
