Prevalence of overweight and obesity in urban schools in Kamsar Republic of Guinea

Introduction. Overweight is a consequence of nutritional transitions, seden-tarity lifestyle, and poverty. Objective. To determine the prevalence of overweight in schools. Population and methods. This was a descriptive cross-sectional study, uni and bi varied analytics, and logistic regression. The CHI2 of Pearson, and Wald have been ap-plied. Odds ratio (OR), and risk factors were estimated. Results. Data concerned 300 children (49% of boys), with a sex ratio of 1.02, an average age of 14 (±2 years), and an overweight of 25%. Factors associated with overweight were ethnicity type [P - 0.000 (OR to 95%) 1.00 (0.000 – 2.000)], gender [P - 0.006 (OR to 95% CI) 2.00 (1.000 – 3.000)], family history: obesity [P - 0.000 (OR to 95% CI) 3.00 (1.000 – 6.000)], high blood pressure (HBP) [P - 0.015 (OR to 95% CI) 1.00 (1.000 – 3.000)],type 2 diabetes (T2D) [P - 0.002 (OR to 95% CI) 2.00 (1.000 – 4.000)], meals number [P - 0.000 (OR to 95% CI) 3.00 (2.000 – 6.000)], activities by week [P - 0.000 (OR to 95% CI) 4.00 (2.000 – 7.000)], and age [P - 0.000 (OR to 95% CI) 7.00 (4.068 –12.000)]. Conclusion. Overweight is high in boys. Family history, as obesity, T2D, HBP, meals number, lacks of activities increase this risk.

Public perception and characteristics related to acceptance of the sugar-sweetened beverage taxation launched in France in 2012

Objective

In France, an excise tax on sugar-sweetened beverages was introduced on 1 January 2012. Our objective was to assess perception of this tax as well as the sociodemographic characteristics of its supporters and opponents.

Design

Cross-sectional study within the Nutrinet-Santé cohort. A sub-sample of 1996 individuals was selected among participants in the Nutrinet-Santé cohort study. Perceptions of the sugar-sweetened beverage tax were assessed via self-administered questionnaires. The sociodemographic and dietary profiles of supporters and opponents of this tax were explored by multinomial logistic regression.

Setting

Nationally representative French sample, 2012.

Subjects

Adults aged >18 years (largest sample n 1996).

Results

Half of the study sample was generally supportive of the tax and 57·7 % perceived it as helpful in improving population health. Participants were more likely to support the tax model if the revenue it generated would be used for health-care system improvement (72·7 %) and if such taxing was associated with a corresponding decrease in the prices of other foodstuffs (71·5 %). Older participants were more likely to support the tax than were their younger counterparts (OR=2·37; 95 % CI 1·60, 3·49 for >65 years v. 26–45 years; P<0·001). Participants with lower educational levels were less likely to support the tax than were those with more formal education (OR=0·31; 95 % CI 0·19, 0·52 for low educational level v. high education level; P<0·001). In our models, sugar-sweetened beverage consumption was not associated with tax perception.

Conclusions

The French sugar-sweetened beverage tax appeared to be favourably perceived by the public. Sociodemographic factors modulated such perceptions and should thus be taken into consideration when drafting future public health measures.

Reviews examining sugar-sweetened beverages and body weight: correlates of their quality and conclusions

BACKGROUND

The role of sugar-sweetened beverages (SSBs) in increasing obesity is of great scientific, clinical, and public health interest. Many reviews have been published on this topic in recent years with very different conclusions.

OBJECTIVE

We sought to assess the scientific quality and other characteristics that may be associated with the conclusions of reviews regarding the causal relation between SSB consumption and body weight.

DESIGN

A systematic search of reviews in English language-published peer-reviewed journals in 2006-2013 was performed. Their methodologic quality was assessed by 2 judges using 2 scoring systems: the Assessment of Multiple Systematic Reviews and the American Dietetic Association Quality Criteria Checklist. The conclusions were blindly assessed by 11 independent readers using a Likert scale ranging from a position score of 0 = no evidence of a causal relation to 5 = strong evidence of a causal relation.

RESULTS

Twenty reviews were identified: 5 meta-analyses, 3 qualitative systematic reviews, and 12 qualitative nonsystematic reviews. Four received funding from the food industry. Quality scores were neither correlated with the readers' perception of conclusions nor with the source of funding. However, industry-funded reviews were more likely to suggest that evidence supporting a causal relation between SSB consumption and weight gain was weak (mean position score = 1.78), whereas evidence was generally considered well-founded in other reviews (mean position score = 3.39; P ≤ 0.01).

CONCLUSIONS

For a complex and controversial scientific issue, it is important to minimize perceived or actual threats to scientific objectivity and methodologic quality. More refined tools are needed to better assess their scientific quality and to identify factors and mechanisms that may influence authors' conclusions.
