Project description:Spain ranks fifth among European countries for childhood obesity. Sugar-sweetened beverages (SSBs) and soft drinks (SDs) are consumed by 81% of the Spanish children weekly. Advertising is one of the factors that contributes to an obesogenic environment. This study correlated longitudinally the nutritional values of SSBs and SDs and advertising discursive strategies between 2013 and 2018 for all media. A mixed-methods approach was applied that included a quantitative analysis of advertising spend data, a content analysis and a study of the discursive strategies used in advertisements. In addition, the Nutri-score system was used in order to determine the nutritional quality of the beverages. The results were analyzed applying the Spanish advertising regulatory framework for obesity prevention. The main findings indicate an association between low nutritional value beverage advertisements and a discourse based on hedonistic elements. In order to prevent childhood obesity in Spain, a stricter regulation of advertising is necessary, especially in aspects such as the language used to present products and celebrity endorsements.

Project description:Biological mechanisms underlying the association between obesity and depression remain unclear. We investigated the role of metabolites and DNA methylation as mediators of the relationship between childhood obesity and subsequent poor mental health in the English Avon Longitudinal Study of Parents and Children. Obesity was defined according to United Kingdom Growth charts at age 7 years and mental health through the Short Mood and Feelings Questionnaire (SMFQ) completed at age 11 years. Metabolites and DNA methylation were measured by nuclear magnetic resonance spectroscopy and Illumina array in blood at the age of 7 years. The associations between obesity and SMFQ score, as continuous count data or using cut-offs to define depressive symptoms (SMFQ >7) or depression (SMFQ >11), were tested using adjusted Poisson and logistic regression. Candidate metabolite mediators were identified through metabolome-wide association scans for obesity and SMFQ score, correcting for false-discovery rate. Candidate DNA methylation mediators were identified through testing the association of putative BMI-associated CpG sites with SMFQ scores, correcting for look-up false-discovery rate. Mediation by candidate molecular markers was tested. Two-sample Mendelian randomization (MR) analyses were additionally applied to test causal associations of metabolites with depression in independent adult samples. 4,018 and 768 children were included for metabolomics and epigenetics analyses, respectively. Obesity at 7 years was associated with a 14% increase in SMFQ score (95% CI: 1.04, 1.25) and greater odds of depression (OR: 1.46 (95% CI: 0.78, 2.38) at 11 years. Natural indirect effects (mediating pathways) between obesity and depression for tyrosine, leucine and conjugated linoleic acid were 1.06 (95% CI: 1.00, 1.13, proportion mediated (PM): 15%), 1.04 (95% CI: 0.99, 1.10, PM: 9.6%) and 1.06 (95% CI: 1.00, 1.12, PM: 13.9%) respectively. In MR analysis, one unit increase in tyrosine was associated with 0.13 higher log odds of depression (p = 0.1). Methylation at cg17128312, located in the FBXW9 gene, had a natural indirect effect of 1.05 (95% CI: 1.01,1.13, PM: 27%) as a mediator of obesity and SMFQ score. Potential biologically plausible mechanisms involving these identified molecular features include neurotransmitter regulation, inflammation, and gut microbiome modulation. These results require replication in further observational and mechanistic studies.

Project description:INTRODUCTION:Child-directed TV advertising is believed to influence children's diets, yet prospective studies in naturalistic settings are absent. This study examined if child-directed TV advertisement exposure for ten brands of high-sugar breakfast cereals was associated with children's intake of those brands prospectively. METHODS:Observational study of 624 preschool-age children and their parents conducted in New Hampshire, 2014-2015. Over 1 year, parents completed a baseline and six online follow-up surveys, one every 8 weeks. Children's exposure to high-sugar breakfast cereal TV advertisements was based on the network-specific TV programs children watched in the 7 days prior to each follow-up assessment, and parents reported children's intake of each advertised high-sugar breakfast cereal brand during that same 7-day period. Data were analyzed in 2017-2018. RESULTS:In the fully adjusted Poisson regression model accounting for repeated measures and brand-specific effects, children with high-sugar breakfast cereal advertisement exposure in the past 7 days (i.e., recent exposure; RR=1.34, 95% CI=1.04, 1.72), at any assessment in the past (RR=1.23, 95% CI=1.06, 1.42), or recent and past exposure (RR=1.37, 95% CI=1.15, 1.63) combined had an increased risk of brand-specific high-sugar breakfast cereal intake. Absolute risk difference of children's high-sugar breakfast cereal intake because of high-sugar breakfast cereal TV advertisement exposure varied by brand. CONCLUSIONS:This naturalistic study demonstrates that child-directed high-sugar breakfast cereal TV advertising was prospectively associated with brand-specific high-sugar breakfast cereal intake among preschoolers. Findings indicate that child-directed advertising influences begin earlier and last longer than previously demonstrated, highlighting limitations of current industry guidelines regarding the marketing of high-sugar foods to children under age 6 years.

Project description:ImportanceRestaurants spend billions of dollars on marketing. However, little is known about the association between restaurant marketing and obesity risk in adults.ObjectiveTo examine associations between changes in per capita county-level restaurant advertising spending over time and changes in objectively measured body mass index (BMI) for adult patients.Design, setting, and participantsThis cohort study used regression models with county fixed effects to examine associations between changes in per capita county-level (370 counties across 44 states) restaurant advertising spending over time with changes in objectively measured body mass index (BMI) for US adult patients from 2013 to 2016. Different media types and restaurant types were analyzed together and separately. The cohort was derived from deidentified patient data obtained from athenahealth. The final analytic sample included 5 987 213 patients, and the analysis was conducted from March 2018 to November 2019.ExposurePer capita county-level chain restaurant advertising spending.Main outcomes and measuresIndividual-level mean BMI during the quarter.ResultsThe included individuals were generally older (37.1% older than 60 years), female (56.8%), and commercially insured (53.5%). For the full population of 29 285 920 person-quarters, there was no association between changes in all restaurant advertising per capita (all media types, all restaurants) and changes in BMI. However, restaurant advertising spending was positively associated with weight gain for patients in low-income counties but not in high-income counties. A $1 increase in quarterly advertising per capita across all media and restaurant types was associated with a 0.053-unit increase in BMI (95% CI, 0.001-0.102) for patients in low-income counties, corresponding to a 0.12% decrease in BMI at the 10th percentile of changes in county advertising spending vs a 0.12% increase in BMI at the 90th percentile.Conclusions and relevanceThe results of this study suggest that restaurant advertising is associated with modest weight gain among adult patients in low-income counties. To date, there has been no public policy action or private sector action to limit adult exposure to unhealthy restaurant advertising. Efforts to decrease restaurant advertising in low-income communities should be intensified and rigorously evaluated to understand their potential for increasing health equity.

Project description:BackgroundThe global HIV/AIDS response has advanced in addressing the health and well-being of HIV-positive children. Although attention has been paid to children orphaned by parental AIDS, children who live with HIV-positive caregivers have received less attention. This study compares mental health problems and risk and protective factors in HIV-positive, HIV-affected (due to caregiver HIV), and HIV-unaffected children in Rwanda.MethodsA case-control design assessed mental health, risk, and protective factors among 683 children aged 10 to 17 years at different levels of HIV exposure. A stratified random sampling strategy based on electronic medical records identified all known HIV-positive children in this age range in 2 districts in Rwanda. Lists of all same-age children in villages with an HIV-positive child were then collected and split by HIV status (HIV-positive, HIV-affected, and HIV-unaffected). One child was randomly sampled from the latter 2 groups to compare with each HIV-positive child per village.ResultsHIV-affected and HIV-positive children demonstrated higher levels of depression, anxiety, conduct problems, and functional impairment compared with HIV-unaffected children. HIV-affected children had significantly higher odds of depression (1.68: 95% confidence interval [CI] 1.15-2.44), anxiety (1.77: 95% CI 1.14-2.75), and conduct problems (1.59: 95% CI 1.04-2.45) compared with HIV-unaffected children, and rates of these mental health conditions were similar to HIV-positive children. These results remained significant after controlling for contextual variables, there were no significant differences on mental health outcomes groups, reflecting a potential explanatory role of factors such as daily hardships, caregiver depression, and HIV-related stigma [corrected].ConclusionsThe mental health of HIV-affected children requires policy and programmatic responses comparable to HIV-positive children.

Project description:BackgroundThe International Obesity Task Force (IOTF) and World Health Organization (WHO) body mass index (BMI) cut-offs are widely used to assess child overweight, obesity and thinness prevalence, but the two references applied to the same children lead to different prevalence rates.ObjectivesTo develop an algorithm to harmonize prevalence rates based on the IOTF and WHO cut-offs, to make them comparable.MethodsThe cut-offs are defined as age-sex-specific BMI z-scores, for example, WHO +1 SD for overweight. To convert an age-sex-specific prevalence rate based on reference cut-off A to the corresponding prevalence based on reference cut-off B, first back-transform the z-score cut-offs zA and zB to age-sex-specific BMI cut-offs, then transform the BMIs to z-scores zB,A and zA,B using the opposite reference. These z-scores together define the distance between the two cut-offs as the z-score difference dzA,B=12zB-zA+zA,B-zB,A . Prevalence in the target group based on cut-off A is then transformed to a z-score, adjusted up or down according to dzA,B and back-transformed, and this predicts prevalence based on cut-off B. The algorithm's performance was tested on 74 groups of children from 14 European countries.ResultsThe algorithm performed well. The standard deviation (SD) of the difference between pairs of prevalence rates was 6.6% (n = 604), while the residual SD, the difference between observed and predicted prevalence, was 2.3%, meaning that the algorithm explained 88% of the baseline variance.ConclusionsThe algorithm goes some way to addressing the problem of harmonizing overweight and obesity prevalence rates for children aged 2-18.

Project description:The rising rate of conflicts and the unsafe situation caused by reasons of ethnicity, religion, gender, sexual orientation, political opinion, or nationality entail an increase in the number of migratory movements. The goal of this article is to describe the health status of asylum seekers visited in an international health center. We conducted a retrospective study of the asylum seekers visited between July 2013 and June 2016. A total of 303 cases were included. The median age was 28.0 years (interquartile range [IQR]: 21-35), and 203 (67.0%) were men. Of the total, 128 cases (42.2%) were from Asia, 82 (27.1%) from Eastern Europe, 42 (13.9%) from sub-Saharan Africa, 34 (11.2%) from America, and 17 (5.6%) from Maghreb. The majority, 287 (94.7%), were asymptomatic. Seventy of the 303 (23.1%) cases were diagnosed with at least one infection, this being more prevalent in men; migrants from sub-Saharan Africa; and in those who took a land-maritime migratory route. Eight of the 303 (2.6%) cases were referred to the transcultural psychiatric department. Two important challenges of the study were the communication barriers and the legal or social situation that condition the psychological symptoms. In 48 of the 303 (15.8%) cases, there was diagnosed a noncommunicable diseases. The process of care was completed by 82.5%; although 21.9% completed the vaccination for hepatitis B. The asylum seekers in this study were in general healthy young men, although special attention was given to infectious diseases with certain geoepidemiological backgrounds. Unstable living arrangements, linguistic, and cultural barriers could account for the failure of the course of care.

Project description:BackgroundWithout addressing the constraints specific to disadvantaged populations, national health policies such as universal health coverage risk increasing equity gaps. Health system constraints often have the greatest impact on disadvantaged populations, resulting in poor access to quality health services among vulnerable groups.MethodsThe Investment Cases in Indonesia, Nepal, Philippines, and the state of Orissa in India were implemented to support evidence-based sub-national planning and budgeting for equitable scale-up of quality MNCH services. The Investment Case framework combines the basic setup of strategic problem solving with a decision-support model. The analysis and identification of strategies to scale-up priority MNCH interventions is conducted by in-country planners and policymakers with facilitation from local and international research partners.ResultsSignificant variation in scaling-up constraints, strategies, and associated costs were identified between countries and across urban and rural typologies. Community-based strategies have been considered for rural populations served predominantly by public providers, but this analysis suggests that the scaling-up of maternal, newborn, and child health services requires health system interventions focused on 'getting the basics right'. These include upgrading or building facilities, training and redistribution of staff, better supervision, and strengthening the procurement of essential commodities. Some of these strategies involve substantial early capital expenditure in remote and sparsely populated districts. These supply-side strategies are not only the 'best buys', but also the 'required buys' to ensure the quality of health services as coverage increases. By contrast, such public supply strategies may not be the 'best buys' in densely populated urbanised settings, served by a mix of public and private providers. Instead, robust regulatory and supervisory mechanisms are required to improve the accessibility and quality of services delivered by the private sector. They can lead to important maternal mortality reductions at relatively low costs.ConclusionsNational strategies that do not take into consideration the special circumstances of disadvantaged areas risk disempowering local managers and may lead to a "business-as-usual" acceptance of unreachable goals. To effectively guide health service delivery at a local level, national plans should adopt typologies that reflect the different problems and strategies to scale up key MNCH interventions.
