Energy Labelling

Mandatory energy (calorie) labelling of alcoholic drinks is a public health measure that could be used to address both alcohol consumption and obesity. We systematically reviewed studies examining consumer knowledge of the energy content of alcoholic drinks, public support for energy labelling and the effect of energy labelling of alcoholic drinks on consumption behaviour. Eighteen eligible studies (from 16 sources) were included. Among studies examining consumer knowledge of the energy content of alcoholic drinks (N=8) and support for energy labelling (N=9), there was moderate evidence that people tend to be unaware of the energy content of alcoholic drinks (pooled estimate: 74% [95% CIs 64-82%] of participants inaccurate estimating energy content) and support energy labelling (pooled estimate: 64% [95% CIs 53%-73% support policy]. Six studies examined the effect of energy labelling on consumer behaviour and findings were indicative of no likely effect of labelling. However, the majority of studies were of low methodological quality, used proxy outcome measures and none of the studies were conducted in real-world settings, resulting in a very low level of evidence. Further research is required to determine whether energy labelling of alcoholic drinks affects consumer behaviour and is likely to be an effective public health policy.

Selection Of

Reducing harmful consumption of food (including non-alcoholic drinks) and alcoholic drinks would prevent much disease. Evidence from tobacco control shows that placing health warning labels (HWLs) on these products reduces their selection and consumption. A systematic review with meta-analysis was conducted using Cochrane methods to assess the impact on selection (including hypothetical selection) or consumption of food or alcoholic drinks with image-and-text (sometimes termed ‘pictorial’) and text-only HWLs placed on these products. Studies were required to be randomised or quasi-randomised controlled trials. Fourteen studies were included, three on alcohol, eleven on food. For our primary outcomes, eleven studies measured selection and one measured consumption (two measured only other secondary outcomes). Meta-analysis of twelve comparisons from nine studies (n=12,635) found HWLs reduced selection of the targeted product compared to a control group with no HWL (RR=0.74 (95% CI 0.68 to 0.80)), with participants 26% less likely to choose a product displaying a HWL. A planned subgroup analysis suggested a larger effect on selection of image-and-text HWLs (RR=0.65 (95% CI 0.54 to 0.80)) than text-only HWLs (RR=0.79 (95% CI 0.74 to 0.85)), but this difference was not statistically significant. These findings suggest significant potential for HWLs to reduce selection of food and alcohol, but all experimental studies to date were conducted in laboratory or online settings with outcomes assessed immediately after a single exposure. Studies in field and more naturalistic laboratory settings are urgently needed to estimate the potential effects of HWLs on food and alcohol.

Abstract. Backgrounds: Central obesity, as a pivotal component of metabolic syndrome is associated with numerous co-morbidities. Dietary factors influence central obesity by increased inflammatory status. However, recent studies didn’t evaluate the association between central obesity and dietary inflammation index (DII®) that give score to dietary factors according to their inflammatory potential. In the current systematic review and meta-analysis, we summarized the studies that investigated the association between DII® with central obesity indices in the general populations. Methods: In a systematic search from PubMed, SCOPUS, Web of Sciences and Cochrane electronic databases, we collected relevant studies written in English and published until 30 October 2019. The population of included studies were apparently healthy subjects or individuals with obesity or obesity-related diseases. Observational studies that evaluated the association between DII® and indices of central obesity including WC or WHR were included. Results: Totally thirty-two studies were included; thirty studies were cross-sectional and two were cohort studies with 103071 participants. Meta-analysis of observational studies showed that higher DII® scores were associated with 1.81 cm increase in WC (Pooled weighted mean difference (WMD) = 1.813; CI: 0.785–2.841; p = 0.001). Also, a non-significant increase in the odds of having higher WC (OR = 1.162; CI: 0.95–1.43; p = 0.154) in the highest DII category was also observed. In subgroup analysis, the continent, dietary assessment tool and gender were the heterogeneity sources. Conclusion: The findings proposed that adherence to diets with high DII® scores was associated with increased WC. Further studies with interventional designs are necessary to elucidate the causality inference between DII® and central obesity indices.
