“…In addition, no clear message emerged regarding whether peers, teachers or professionals were more effective at instigating behaviour change. One promising approach 19, which has been implemented in the South West of England and south Wales, utilized successfully the diffusion of innovations model 58. This model explains how innovations are communicated to members of a social system through various channels over time 58.…”

In this programme (ASSIST), ‘peer supporters’ communicated smoking prevention messages informally to their friends as part of their usual social interactions.…”

Background and AimsPeer‐led interventions may offer a beneficial approach in preventing substance use, but their impact has not yet been quantified. We conducted a systematic review to investigate and quantify the effect of peer‐led interventions that sought to prevent tobacco, alcohol and/or drug use among young people aged 11–21 years.MethodsMedline, EMBASE, PsycINFO, CINAHL, ERIC and the Cochrane Library were searched from inception to July 2015 without language restriction. We included randomized controlled trials only. Screening and data extraction were conducted in duplicate and data from eligible studies were pooled in a random effects meta‐analysis.ResultsWe identified 17 eligible studies, approximately half of which were school‐based studies targeting tobacco use among adolescents. Ten studies targeting tobacco use could be pooled, representing 13 706 young people in 220 schools. Meta‐analysis demonstrated that the odds of smoking were lower among those receiving the peer‐led intervention compared with control [odds ratio (OR) = 0.78, 95% confidence interval (CI) = 0.62–0.99, P = 0.040]. There was evidence of heterogeneity (I 2 = 41%, χ2 15.17, P = 0.086). Pooling of six studies representing 1699 individuals in 66 schools demonstrated that peer‐led interventions were also associated with benefit in relation to alcohol use (OR = 0.80, 95% CI = 0.65–0.99, P = 0.036), while three studies (n = 976 students in 38 schools) suggested an association with lower odds of cannabis use (OR = 0.70, 0.50–0.97, P = 0.034). No studies were found that targeted other illicit drug use.ConclusionsPeer interventions may be effective in preventing tobacco, alcohol and possibly cannabis use among adolescents, although the evidence base is limited overall, and is characterized mainly by small studies of low quality.

“…In our case, decision-making is the mental process that leads to a choice of adoption or rejection of stone bunds (Rogers 2002). In his theory of innovation diffusion, Rogers (1995) suggests five stages through which an individual passes during the innovation decision-making process: (1) knowledge; (2) persuasion; (3) decision; (4) implementation; and (5) confirmation.…”

This study aims to identify key differences between farmers who spontaneously implement stone bunds (i.e. farmers implementing stone bunds by their own initiative) and farmers who do not. Data were collected in the Girar Jarso woreda in the central highlands of Ethiopia, through a household survey with 80 farmers: 40 with spontaneously implemented stone bunds and 40 without. Independent samples t test, principal component analysis and regression analysis were used to analyse the data. Results show that five key-factors explain differences between the two groups of farmers: (1) readiness to change, (2) available resources, (3) social capital, (4) type of family, and (5) commitment. These factors together explain 73% of the variance in the data set and show that particularly characteristics related to the farmer's intrinsic motivation play a crucial role to spontaneously implement and integrate stone bunds into the farming system. Furthermore, results show that young farmers are most committed to soil conservation: they are often intrinsically motivated dynamic farmers who are ready to change their future and improve productivity and food security. The study suggests that government extension programmes should therefore focus more on these young and dynamic farmers and foster their readiness to change. This implies that extension workers and government officials should better understand the crucial role of farmers' intrinsic motivation when dealing with sustainable land management, and also reformulate extension strategies and messages. This is particularly important when developing a scaling-up strategy that helps to sustainably increase agricultural production and achieve food security of small-holder farmers in Ethiopia.

“…International cohort studies completed before the turn of the century seem to point in the opposite direction (35)(36)(37) . Previous theoretical approaches (20,21) , international comparisons (22) and Finnish cross-sectional studies (24,25,38,39) have suggested that gender and socio-economic status are associated with dietary changes. The present study supports the assumption regarding women as nutritional gatekeepers and pioneers of dietary changes.…”

“…However, we are not aware of comparable longitudinal population studies analysing multiple social predictors -for instance gender, education, marital status -and health-related predictors of dietary change in representative samples of working-age populations, particularly regarding the recent changes in the use of bread spreads. Studies on the social determinants of favourable health behaviour change (18,19) have applied the theoretical approaches of Rogers (20) and Bourdieu (21) . The two approaches lead to the assumption of higher social classes as pioneers of modern and healthier dietary practices.…”

Objective: Finland is known for a sharp decrease in the intake of saturated fat and cardiovascular mortality. Since 2000, however, the consumption of butter-containing spreads -an important source of saturated fats -has increased. We examined social and health-related predictors of the increase among Finnish men and women. Design: An 11-year population follow-up. Setting: A representative random sample of adult Finns, invited to a health survey in 2000. Subjects: Altogether 5414 persons aged 30-64 years at baseline in 2000 were re-invited in 2011. Of men 1529 (59 %) and of women 1853 (66 %) answered the questions on bread spreads at both time points. Respondents reported the use of bread spreads by choosing one of the following alternatives: no fat, soft margarine, butter-vegetable oil mixture and butter, which were later categorized into margarine/no spread and butter/butter-vegetable oil mixture ( = butter). The predictors included gender, age, marital status, education, employment status, place of residence, health behaviours, BMI and health. Multinomial regression models were fitted. Results: Of the 2582 baseline margarine/no spread users, 24.6% shifted to butter. Only a few of the baseline sociodemographic or health-related determinants predicted the change. Finnish women were more likely to change to butter than men. Living with a spouse predicted the change among men. Finland is known for its successful health policies to reduce CVD. Since the late 1960s cardiovascular mortality and serum cholesterol levels have decreased remarkably (1,2) . The decrease in serum cholesterol can mainly be explained by changes in dietary fats. The proportion of saturated fat in the total energy intake has decreased (3,4) and the consumption of bread spreads has changed accordingly. In the late 1970s over 60 % of Finns used butter on bread (5) . In 2000 only 6 % used butter while butter-vegetable oil mixture was used by 17 % (6) . The changes have been interpreted as examples of successful food and nutrition policies and dietary interventions (7,8) . Based on the Finnish Food Balance Sheets, butter consumption began to increase in 2005 after a steady decrease previously (9) . The changing trend in consumption of butter-containing fats was also revealed by cross-sectional surveys (10) . The percentage contribution to total energy intake (E%) from fat increased between 2007 and 2012, from 33 to 36 E% among men and from 31 to 36 E% among women. The intake of saturated fat increased from 14 to 15 E% among men and from 13 to 15 E% among women. Serum cholesterol levels increased congruently: among men from 5·25 to 5·34 mmol/l and among women from 5·15 to 5·31 mmol/l (11) . In 2012, more than 40 % of saturated fat was obtained from dairy products. Among Finnish men aged 25-64 years, the most important sources of saturated fat were dishes prepared with meat or meat products (15 %), butter and butter-containing bread spreads (14 %) and
