Changes in self-reported energy balance behaviours and body mass index during a mass media campaign
ABSTRACT Prevention of (serious) overweight can be achieved by means of small behaviour changes in physical activity and/or diet.
To evaluate a mass media campaign promoting energy balance behaviours in a Dutch population. Effects were examined for body mass index (BMI) and five energy balance behaviours.
A representative cohort study of 1200 Dutch adults was employed. Data were collected at four moments. Two campaign waves were launched, following T1 (targeting the general adult population) and T2 [targeting low socio-economic status (SES) men], respectively. Regression analyses were performed to estimate the short-term and long-term effects of campaign exposure.
In total, data of 1030 participants (86%) were available. Time trends showed unfavourable changes in most but not all energy balances behaviour for the total sample. No differences were found for BMI. No differences in the outcome measures were found as a result of exposure to the first campaign (19%). A short-term effect of exposure to the second campaign (29% exposure) was found (T2-T3), but only for low SES respondents, with increases in the attention being paid towards food choice (P = 0.02). At long term, BMI was less likely to increase among exposed people with a non-Dutch ethnicity (P = 0.01, T2-T4).
Exposure to the campaign was low. The first campaign wave had no effects on BMI and energy balance behaviours. Small but favourable changes in attention towards food choice and BMI for at-risk populations were observed among those exposed to the second campaign wave.

ABSTRACT: This supplement presents the papers from the Heelsum International Workshop on Nutrition in General Practice, held in Heelsum, near Wageningen in the Netherlands, on 13–15 December 2010. The authors came from the Netherlands, USA, UK, Germany, Portugal, Spain, Iran and Australia. It was the 6th of these Heelsum workshops, held every 3 years, in 1995, 1998, 2001, 2003, 2007 and now 2010; all have been published in full in the American Journal of Clinical Nutrition,1 the European Journal of Clinical Nutrition,2 the American Journal of Clinical Nutrition,3 the European Journal of Clinical Nutrition,4 Family Practice5 and again in Family Practice. This series of workshops have provided experiences and research from inside general practice. The last 15 years have seen major changes in general practice. Computers now routinely used by doctors in their consulting room capture clinical observations and access remote information. Patients increasingly search the Internet for their symptoms or disease name. Overweight and obesity have increased so much that GPs are expected to advise patients on its management even if this is not the presenting complaint. At the same time, it has become obvious that GPs cannot control the obesity epidemic on their own. Nor can they expect to be successful with most of their individual patients without referral, access and support to and from community resources. Community actions are also essential, requiring policy and resource support from national governments, mass media, municipalities, sports facilities, public transport, schools and the food industry. Overweight/obesity now affects children, adolescents and adults. In the field of obesity, primary care and public health can form natural alliances with supermarkets, food industry, schools, gymnastics, sporting clubs, employers, child protection and medical insurance.6 The other theme of this 6th workshop is undernutrition in old … Articles citing this article L.E.A.D.: A Framework for Evidence Gathering and Use for the Prevention of Obesity and Other Complex Public Health Problems Health Educ Behav (2014) 41 (1): 85-99 AbstractFull Text (HTML)Full Text (PDF) A longitudinal study of changes in noticing and treating patients' overweight by Dutch GPs between 1997 and 2007 Fam Pract (2012) 29 (suppl_1): i61-i67 AbstractFull Text (HTML)Full Text (PDF) Family Practice (2012) 29 (suppl 1): i6-i9. doi: 10.1093/fampra/cmr058 This article appears in:Practice-based evidence for weight management: alliance between primary care and public health » ExtractFree Full Text (HTML)Free Full Text (PDF)FreeFamily Practice 04/2012; 29 Suppl 1:i6-9.

ABSTRACT: The prevalence of obesity is significantly higher among American Indians (AIs) and is associated with increased rates of diabetes, hypertension, and cardiovascular disease. We implemented a 14-mo intervention trial (Navajo Healthy Stores) on the Navajo Nation that sought to increase availability of healthier foods in local food stores and to promote these foods at the point of purchase and through community media. We divided the Navajo Nation into 10 store regions, half of which were randomized to intervention and half to comparison. We evaluated the program by using a pre-post sample of systematically sampled adult Navajo consumers (baseline, n = 276; postintervention, n = 145). Intervention impact was examined by analyzing pre-post differences by intervention group and by intervention exposure level. When intervention and comparison groups were compared, only body mass index (BMI) showed a trend toward impact of the intervention (P = 0.06). However, greater exposure to the intervention was associated with significantly reduced BMI (P ≤ 0.05) and improved healthy food intentions (P ≤ 0.01), healthy cooking methods (P ≤ 0.05), and healthy food getting (P ≤ 0.01). With increasing exposure, the odds of improving overweight or obese status was 5.02 (95% CI: 1.48, 16.99; P ≤ 0.01) times the odds of maintaining or worsening overweight or obese status. In summary, a food store intervention was associated with reduced overweight/obesity and improved obesity-related psychosocial and behavioral factors among those persons most exposed to the intervention on an AI reservation.Journal of Nutrition 07/2013; 143(9).

ABSTRACT: Mass media campaigns are frequently used to influence the health behaviors of various populations. There are currently no quantitative meta-analyses of the effect of mass media campaigns on physical activity in adults. We searched six electronic databases from their inception to August 2012 and selected prospective studies that evaluated the effect of mass media campaigns on physical activity in adults. We excluded studies that did not have a proper control group or did not report the uncertainties of the effect estimates. Two reviewers independently screened the title/abstracts and full articles. We used random-effects models to pool effect estimates across studies for 3 selected outcomes. Nine prospective cohorts and before-after studies that followed-up 27,601 people over 8 weeks to 3 years met the inclusion criteria. Based on the pooled results from these studies, mass media campaigns had a significant effect on promoting moderate intensity walking (pooled relative risk (RR) from 3 studies=1.53, 95% Confidence Interval: 1.25 to 1.87), but did not help participants achieve sufficient levels of physical activity [4 studies pooled RR=1.02, 95% CI: 0.91 to 1.14)]. The apparent effect of media campaigns on reducing sedentary behavior (pooled RR=1.15, 95% CI: 1.03 to 1.30) was lost when a relatively low-quality study with large effects was excluded in a sensitivity analysis. In subgroup analyses, campaigns that promoted physical activity as a 'social norm' seemed to be more effective in reducing sedentary behavior. Mass media campaigns may promote walking and reduce sedentary behavior, but may not lead to achieving recommended levels of overall physical activity. Further research is warranted on different campaign types and in low- and middle- income countries.Archives of Public Health 08/2013; 71(1):20. DOI:10.1186/0778-7367-71-20
