Can Food and Beverage Advertising Questionnaire Predict Overweight and Obesity in Children and Adolescents from Low- and Middle-Income Countries?

Background: Information about the reliability and validity of questionnaires in low- and middle-income countries remains scarce. Objective: To test the reliability and predictive validity of a food and beverage marketing/advertising questionnaire for South American children and adolescents. Methods: A sample of 330 children (3-10 years old) and 215 adolescents (11-18 years old) was included from seven South American cities: Buenos Aires, Lima, Medellín, Montevideo, Santiago, Sao Paulo, and Teresina. The questionnaire consisted of seven questions about food and beverage marketing/advertising and decision influence. We assessed the reliability using temporal stability (2-week interval) and internal consistency. We assessed the predictive validity based on the risk of excess weight. Results: In children, reliability agreement from κ coefficients ranged from 63.7% to 86.3%, and Cronbach's α (internal consistency estimate) ranged from 0.14 to 0.75. In adolescents, the reliability agreement ranged from 78.9% to 85.7%, and Cronbach's α ranged from 0.14 to 0.76. Exploratory factor analysis revealed two factors for both age groups. The predictive probabilities for excess weight ranged from 22.3% to 61.1% in children and from 24.9% to 64.1% in adolescents. Conclusions: The screen/marketing media questionnaire is a reliable and valid measure for the pediatric population from low- and middle-income countries. This subjective tool provides a feasible screening measure for the influence of advertising on children and adolescents at risk of overweight and obesity.

Evaluation of the Validity of a Food Frequency Questionnaire and 24-Hour Dietary Recall to Assess Dietary Iron Intake in Children and Adolescents from the South American Youth/Child Cardiovascular and Environmental Study.

BACKGROUND: A food frequency questionnaire (FFQ) for South American children and adolescents was developed, but its validity for assessing dietary iron intake has not been evaluated. OBJECTIVE: To evaluate the validity of the FFQ and 24-hour dietary recalls (24h-DR) for assessing dietary iron intake in children and adolescents. DESIGN: The South American Youth/Child Cardiovascular and Environmental study is a multicenter observational study, conducted in five South American cities: Buenos Aires (Argentina), Lima (Peru), Medellin (Colombia), Sao Paulo, and Teresina (Brazil). The FFQ assessed dietary intake over the previous 3 months, and the 24h-DR was completed three times (2 weekdays and 1 weekend day) with a minimum 5-day interval between recalls. Blood samples were collected to assess serum iron, ferritin, and hemoglobin levels. PARTICIPANTS AND SETTING: Data of 99 children (aged 3 to 10 years) and 50 adolescents (aged 11 to 17 years) from public and private schools were collected during 2015 to 2017. MAIN OUTCOME MEASURES: Dietary iron intake calculated from the FFQ (using the sum of daily iron intake in all food/food groups) and 24h-DR (mean of 3 days using the multiple source method). STATISTICAL ANALYSES PERFORMED: Dietary iron intake in relation to blood biomarkers were assessed using Spearman rank correlations adjusted for sex, age, and total energy intake, and the quadratic weighted κ coefficients for agreement. RESULTS: Spearman correlations showed very good coefficients (range = 0.78 to 0.85) for the FFQ in both age groups; for the 24h-DR, the coefficients were weak in children and adolescents (range = 0.23 to 0.28). The agreement ranged from 59.9% to 72.9% for the FFQ and from 63.9% to 81.9% for the 24h-DR. CONCLUSION: The South American Youth/Child Cardiovascular and Environmental study FFQ exhibited good validity to rank total dietary iron intake in children and adolescents, and as well as the 24h-DR, presented good strength of agreements when compared with serum iron and ferritin levels.

Metabolic syndrome may be associated with a lower prevalence of iron deficiency in Ecuadorian women of reproductive age.

The present study aimed to assess the associations of the stages of Fe deficiency (Fe deficiency without anaemia (ID) and Fe-deficiency anaemia (IDA)) and anaemia with metabolic syndrome (MetS) in Ecuadorian women. A cross-sectional study was conducted in 5894 women aged 20-59 years, based on data from the 2012 Ecuadorian National Health and Nutrition Survey. The sample was stratified by age. A χ2 test was used to assess the possible associations of ID, IDA and anaemia with MetS. The prevalence ratio (PR) for each stage of Fe deficiency and anaemia was estimated considering women without MetS as a reference. The total prevalence of MetS, ID, IDA and anaemia was 32⋅3 % (se 0⋅6), 6⋅2 % (se 0⋅3), 7⋅1 % (se 0⋅3) and 5⋅0 % (se 0⋅3), respectively. In women aged 20-29, 30-39 and 40-49 years, MetS was associated with a lower prevalence of ID (PR (95 % CI; P-value)): 0⋅17 (0⋅06, 0⋅46; P < 0⋅001), 0⋅69 (0⋅48, 0⋅99; P = 0⋅044) and 0⋅44 (0⋅29, 0⋅67; P < 0⋅001), respectively. In women aged 50-59 years, MetS was associated with IDA and anaemia (PR (95 % CI; P-value)): 0⋅12 (0⋅02, 0⋅96; P = 0⋅026) and 0⋅22 (0⋅07, 0⋅64; P = 0⋅002), respectively. In conclusion, Ecuadorian women of reproductive age with MetS have a lower prevalence of ID compared with those without MetS. Furthermore, the MetS and IDA coexist at the population level. These findings require an analysis from a dietary pattern approach, which could provide key elements for developing public policies that simultaneously address all forms of malnutrition.

Metabolic Syndrome Among Young Health Professionals in the Multicenter Latin America Metabolic Syndrome Study.

Background: Metabolic syndrome (MS) and its components increase the risk of a number of chronic diseases. Evidence regarding its prevalence among health professionals, particularly in Latin America, is limited. The purpose of this study was to assess the overall prevalence of MS and its components among health professionals and students from five Latin American countries. Methods: A cross-sectional multicenter study entitled LATIN America METabolic Syndrome (LATINMETS) was conducted on five groups of apparently healthy volunteer subjects. Sociodemographic factors, lifestyle variables (smoking and physical activity), anthropometric measurements (weight, height, and waist circumference), standard biochemical analyses [triglycerides, glucose, and high-density lipoprotein cholesterol (HDL-C)], and blood pressure measurements were assessed. MS was diagnosed based on internationally harmonized criteria. Associations between MS components and sociodemographic, lifestyle, and anthropometric variables were analyzed using multivariate logistic regression. Results: A total of 1,032 volunteers (n = 316-Mexico, n = 285-Colombia, n = 223-Brazil, n = 132-Paraguay, and n = 76-Argentina) were recruited. The majority of them were women (71.9%), students (55.4%), and younger than 28 years (67.2%). The overall prevalence of age-standardized MS was 15.5% (23.1% men and 12.2% women). The majority (59.3%) presented at least one MS component, mainly abdominal obesity (29.7%) and low HDL-C levels (27.5%). After adjusting for age and sex, MS and its components were positively associated with being overweight or obese. Conclusions: MS prevalence in this study was similar to that generally found among young populations in Latin-American countries. More than half of the sample had at least one MS component, suggesting that preventive measures and treatments aimed at achieving low-risk health status are essential in this population.

Global benchmarking of children's exposure to television advertising of unhealthy foods and beverages across 22 countries.

Restricting children's exposures to marketing of unhealthy foods and beverages is a global obesity prevention priority. Monitoring marketing exposures supports informed policymaking. This study presents a global overview of children's television advertising exposure to healthy and unhealthy products. Twenty-two countries contributed data, captured between 2008 and 2017. Advertisements were coded for the nature of foods and beverages, using the 2015 World Health Organization (WHO) Europe Nutrient Profile Model (should be permitted/not-permitted to be advertised). Peak viewing times were defined as the top five hour timeslots for children. On average, there were four times more advertisements for foods/beverages that should not be permitted than for permitted foods/beverages. The frequency of food/beverages advertisements that should not be permitted per hour was higher during peak viewing times compared with other times (P < 0.001). During peak viewing times, food and beverage advertisements that should not be permitted were higher in countries with industry self-regulatory programmes for responsible advertising compared with countries with no policies. Globally, children are exposed to a large volume of television advertisements for unhealthy foods and beverages, despite the implementation of food industry programmes. Governments should enact regulation to protect children from television advertising of unhealthy products that undermine their health.

Reliability and validity of body weight and body image perception in children and adolescents from the South American Youth/Child Cardiovascular and Environmental (SAYCARE) Study.

OBJECTIVE: To assess the reliability and validity of body weight (BW) and body image (BI) perception reported by parents (in children) and by adolescents in a South American population. DESIGN: Cross-sectional study. BW perception was evaluated by the question, 'Do you think you/your child are/is: severely wasted, wasted, normal weight, overweight, obese?' BI perception was evaluated using the Gardner scale. To evaluate reliability, BW and BI perceptions were reported twice, two weeks apart. To evaluate validity, the BW and BI perceptions were compared with WHO BMI Z-scores. Kappa and Kendall's tau-c coefficients were obtained. SETTING: Public and private schools and high schools from six countries of South America (Argentina, Peru, Colombia, Uruguay, Chile, Brazil).ParticipantsChildren aged 3-10 years (n 635) and adolescents aged 11-17 years (n 400). RESULTS: Reliability of BW perception was fair in children's parents (κ=0·337) and substantial in adolescents (κ=0·709). Validity of BW perception was slight in children's parents (κ=0·176) and fair in adolescents (κ=0·268). When evaluating BI, most children were perceived by parents as having lower weight. Reliability of BI perception was slight in children's parents (κ=0·124) and moderate in adolescents (κ=0·599). Validity of BI perception was poor in children's parents (κ=-0·018) and slight in adolescents (κ=0·023). CONCLUSIONS: Reliability of BW and BI perceptions was higher in adolescents than in children's parents. Validity of BW perception was good among the parents of the children and adolescents with underweight and normal weight.

Unhealthy dietary patterns among healthcare professionals and students in Mexico.

BACKGROUND: While dietary patterns (DPs) enable the combination of foods that make up a person's habitual diet to be known, little is known about the DPs of health sector professionals. The objective of this study was to describe the DPs of healthcare students and professionals and assess their association with sociodemographic, lifestyle, anthropometric and biochemical characteristics. METHODS: Cross-sectional design. A sample (n = 319) of healthcare students and professionals in apparent good health who studied or worked at the University of Guadalajara (Mexico) was selected. A semiquantitative food intake frequency questionnaire validated on a Mexican population was administered. Questions covering sociodemographic factors, smoking habits and physical activity were asked. Weight, height, waist circumference, blood pressure, triglycerides, glucose, HDL-cholesterol, LDL-cholesterol and total cholesterol were also measured. DPs were generated from a principal components analysis of 25 food groups, and associations were analyzed using logistic regression adjusted for age and sex. RESULTS: The majority of participants were younger than 29 years (84%), women (71.2%) and students (59.6%). Three DPs were identified: "Traditional Westernized", "Healthy" and "Animal protein and alcoholic beverages". After adjustment, the "Traditional Westernized" DP was positively associated with being younger than 22 years (OR: 2.15; 95%CI: 1.1-4.1); the "Healthy" DP was positively associated with having a daily energy expenditure from physical activity greater than 605 kcal (OR: 4.19; 95%CI: 2.3-7.5), and it was negatively associated with being younger than 22 years (OR: 0.48; 95%CI: 0.2-0.9); and the "Animal protein and alcoholic beverages" DP was positively associated with being male (OR: 3.07; 95%CI: 1.8-5.1) and a smoker (OR: 2.77; 95%CI: 1.2-6.3). No association was found between DPs and anthropometric and biochemical characteristics. CONCLUSIONS: Among the participants evaluated, healthy DP was associated with being physically active while unhealthy DPs were associated with being younger than 22 years, male and a smoker. These data suggest that being knowledgeable about health does not ensure that individuals will engage in healthy behaviors. As is the case among the general population, training and individual efforts aimed at achieving healthy behaviors must be reinforced by initiatives undertaken by social groups, social institutions, the community at large as well as political and business leaders.

Development of a Food Frequency Questionnaire for Assessing Dietary Intake in Children and Adolescents in South America.

OBJECTIVE: This study aimed to describe the development of a food frequency questionnaire (FFQ) to assess dietary intake in South American children and adolescents. METHODS: A total of 345 children (aged 3-10 years) and 357 adolescents (aged 11-17 years) were included for analysis. The FFQ was designed to be self-administered and to assess dietary intake over the past 3 months. It was developed in Spanish and translated into Portuguese. Multiple approaches were considered to compile the food list, and 11 food groups were included. A food photo booklet was produced as supporting material. RESULTS: The FFQ items maintained a common core list among centers (47 items) and country-specific foods. The FFQ for Buenos Aires and Lima had a total of 63 items; there were 55 items for the FFQ in Medelin, 60 items for Montevideo, 58 items for Santiago, 67 items for Sao Paulo, and 68 items for Teresina. Alcohol was also incorporated in the adolescents' FFQ. CONCLUSIONS: We developed a semiquantitative, culturally adapted FFQ to assess dietary intake in children and adolescents in South America. It has an optimal size allowing its completion in a high proportion of the population; therefore, it can be used in epidemiological studies with South American children and adolescents.

Concentrations of Plasma Free Palmitoleic and Dihomo-Gamma Linoleic Fatty Acids Are Higher in Children with Abdominal Obesity.

Increased plasma free fatty acids (FFAs) are associated with cardiometabolic risk factors in adults with abdominal obesity (AO). However, this association remains controversial in children. This study analyzed plasma FFA concentration in children with and without AO. Twenty-nine children classified with AO were matched by age and sex with 29 non-obese individuals. Blood samples were collected after fasting for 10-12 h. Plasma concentration of glucose, insulin, triglycerides, total cholesterol, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were determined by automatized methods. FFAs were analyzed by gas chromatography. Children with and without AO had similar age (7.1 ± 2.6 vs. 7.2 ± 2.7 years; p > 0.05) but obese children showed higher (p < 0.05) body mass index (BMI) (+4.3 kg/m²), systolic blood pressure (+5.1 mmHg), and insulin (+27.8 pmol/L). There were no significant differences in plasma total FFA concentration between groups (1.02 ± 0.61 vs. 0.89 ± 0.37 mmol/L; p > 0.05). However, children with AO had higher palmitoleic acid (0.94 vs. 0.70 wt %; p < 0.05) and dihomo-gamma linoleic acid (DHGL) (2.76 vs. 2.07 wt %; p < 0.05). Palmitoleic and DHGL acids correlated (p < 0.05) with BMI (r = 0.397; r = 0.296, respectively) and with waist circumference (r = 0.380; r = 0.276, respectively). Palmitoleic acid correlated positively with systolic blood pressure (r = 0.386; p < 0.05) and negatively with HDL-C (-0.572; p < 0.01). In summary, children with AO have higher plasmatic concentrations of free palmitoleic and DHGL fatty acids, which correlate with cardiometabolic risk factors.

Fatty Acid Content of Plasma Triglycerides May Contribute to the Heterogeneity in the Relationship Between Abdominal Obesity and the Metabolic Syndrome.

BACKGROUND: About one-third of the people with abdominal obesity do not exhibit the metabolic syndrome (MetS). Fatty acids in plasma triglycerides (TGs) may help to explain part of this heterogeneity. This study compared TG fatty acid profile of adults with and without abdominal obesity and examined the associations of these fatty acids with MetS components. METHODS: Fifty-four abdominally obese subjects were matched by age and sex with 54 adults without abdominal obesity. People were classified with MetS according to the harmonizing criteria for MetS. Fatty acids in plasma TGs were analyzed by gas chromatography. RESULTS: There were no differences in fatty acids of plasma TGs between people with and without abdominal obesity. However, there were differences between abdominally obese people with and without MetS. The abdominally obese group with MetS had higher palmitic (+2.9%; P = 0.012) and oleic (+4.0%; P = 0.001) acids and lower linoleic (-6.4%; P = 0.018) and arachidonic (-1.2%; P = 0.004) acids. After adjustment for abdominal obesity, age, and sex, a stepwise regression analysis showed that palmitic acid positively contributed to the variance in insulin (ß = +1.08 ± 1.01; P = 0.000) and homeostasis model assessment of insulin resistance (HOMA-IR) index (ß = +1.09 ± 1.01; P = 0.000) and myristic acid positively contributed to the variance in systolic blood pressure (ß = +1.09 ± 1.03; P = 0.006). In contrast, linoleic acid negatively contributed to the variance in glucose (ß = -0.321 ± 0.09; P = 0.001) and high-sensitivity C-reactive protein (hsCRP; ß = -1.05 ± 1.01; P = 0.000). CONCLUSIONS: There were no differences in the plasma TG fatty acid profile between people with and without abdominal obesity. Likewise, fatty acids in plasma TGs associated with many of the MetS variables independently of abdominal obesity. These results suggest that the plasma TG fatty acid profile may help to explain part of the heterogeneity between abdominal obesity and the MetS.

Sistematización de una estrategia de información, educación y comunicación para prevención del síndrome metabólico en profesionales del área de la salud / Systematization of an information, education and communication strategy to prevent the metabolic syndrome in the health care professional

Antecedentes: se realizó una campaña de información, educación y comunicación (IEC) sobre síndrome metabólico para personal universitario del área de la salud, derivada de una investigación realizada en esta población. Objetivo: reconocer las dinámicas y aprendizajes generados en los profesionales ejecutores de la campaña "Somos salud". Metodología: sistematización de experiencia realizada por los ejecutores de la campaña, quienes definieron la pregunta orientadora, reconstruyeron la experiencia, hicieron la reflexión crítica, en la cual identificaron aspectos significativos que permitieron construir y validar el sistema categorial. La información se recolectó mediante grupos focales. Resultados: se identificó como categoría principal: "Aprender en la práctica de la estrategia IEC" y como subcategorías destacadas: la reflexión sobre IEC y educación, la relación extensión-investigación, asuntos críticos de la ejecución y el diseño de mensajes y materiales. Conclusiones: se reconoce que aunque los procesos de IEC no garantizan cambios inmediatos en prácticas individuales y colectivas, contribuyen a conocer y discutir problemáticas de salud. Se reflexionó críticamente sobre la manera como se hace educación para la salud, resaltando la necesidad de considerar aspectos individuales y contextuales, mediadores en las decisiones de salud y reconociendo al profesional de la salud como agente y sujeto de tales decisiones.

Objective: Recognition of dynamics and learning created in the professionals who perform the "We are Health" campaign. Methodology: Systematization of the experience was carried out by the campaign performers; who have defined the guiding question, rebuilt the experience, made a critical reflection, and identified significant aspects in it that let to build and validate the categorical system. By means of focus groups the information was collected. Results: "Learning by doing of the IEC strategy" was identified as the main category, and as emphasized subcategories: the reflection about the IEC and education, the extension-research relationship, critical aspects of the execution and design of messages and materials. Conclusions: Although it is recognized that the IEC processes do not guarantee immediate changes in individual and collective practices, they contribute to know and discuss health related issues. It was critically reflected on the way as education for health is made, emphasizing the need to consider individual and contextual aspects that mediate on health decisions, and the recognition of the health care professional as an agent and subject of such decisions.

Newborn birth weights and related factors of native and immigrant residents of Spain.

Birth weight is a high impact factor in populations with high rates of immigration. This study establishes differences in birth weight (BW) and related factors among full-term newborn (NB) infants born to native and immigrant women living in Spain during 2007-2008. All NBs from Spanish mothers and mothers from the five nationalities with the highest birth rates in Spain (Morocco, Romania, Ecuador, Bolivia, and Colombia) according to the Statistical Bulletin of Births in Spain were included. BW was classified as low BW (LBW; <2,500 g), underweight (UW; 2,500-2,999 g), adequate weight (3,000-3,999 g), and macrosomia (≥4,000 g). The characteristics associated with a higher likelihood of LBW were Spanish mother, lower training level (OR = 1.3), more children (OR = 1.8), age ≤19 years (OR = 1.2) or ≥40 years (OR = 1.3), and female NB. The probability of macrosomia was higher in Bolivian mothers (OR = 3.0) with more children (OR = 1.7) and male NBs (OR = 2.0). The NBs of Spanish mothers have a higher likelihood of LBW and the lowest odds for macrosomía compared with immigrants from the other countries.

Metabolic syndrome in healthcare personnel of the university of Antioquia-Colombia; LATINMETS study.

INTRODUCTION: Hypertension (HTN), atherogenic dyslipidemia, an increased glycemia in a fasting state, and abdominal obesity (AO), constitute a cluster of risk factors for cardiovascular disease named metabolic syndrome (MS). OBJECTIVE: To analyze the prevalence and distribution of MS and its components in healthcare personnel from the University of Antioquia. METHODOLOGY: Cross-sectional study conducted between 2010 and 2011. The collected data included anthropometrical, biochemical, socio-demographic, and lifestyle variables. The MS was diagnosed using the harmonized IDF/AHA definition. Descriptive and analytical statistical analyses were performed, including χ2 tests, and a = 0.05. RESULTS: 285 volunteers (29.1% men) with ages between 20 and 61 years were included. 31.6% of participants were overweight with a Body Mass Index higher than 25 kg/m2 (BMI). AO (29.8%) and HTN (29.8%) were the most frequent components of MS. Global prevalence of MS was 17.5% (95%CI: 13.1; 22). There was a lower presence of MS among women (OR 0.328; 95%CI: 0.175; 0.614; p < 0.05), and a positive gradient with age and income. Likewise, the prevalence of MS was higher among smokers and those who are overweight (p < 0.05). After adjusting for age, MS was associated with sex (OR 0.348; 95%CI: 0.178; 0.680) and being overweight (OR 14.592; 95%CI: 6.343; 33.570). CONCLUSION: The most frequently observed components of MS in the studied sample were AO and HTN. BMI, sex, and socio-economic status are important independent risk factors associated with MS.

The parliamentary political agenda: a tool for policy analysis of diabetes priorities in Spain

Objective: To analyze the political agenda on diabetes in Spain under democracy by considering the frequency and content of initiatives in the Spanish parliament. Methods: A systematic search of parliamentary interventions (1979-2010) reported on the Spanish Congress of Deputies' web page was carried out using the key word "diabetes". A descriptive study of the frequency of interventions was performed, followed by a content analysis, according to the priorities of the World Health Organization (WHO), the International Diabetes Federation and the Spanish Diabetes Federation. Other study variables were the year of presentation, legislature, type of initiative and whether a political decision was taken (yes/no). Results: There were 59 interventions: 22% were related to the first international initiatives and 44.1% took place in the last two legislatures in response to the WHO's program Diabetes Action Now. A total of 32.2% of the initiatives addressed educational and social programs, while 23.7% addressed access to resources and health services. Most initiatives (74.6%) consisted of parliamentary questions to the government, which only required a response. Of the 15 initiatives requiring a decision to be taken, only eight were approved. Conclusions: Spanish legislators aim to comply with international standards. Nevertheless, political decision-making has sometimes been slow. Importantly, most of the political responsibilities related to health have been transferred to the autonomous regions. The updated National Diabetes Strategy in Spain will need to strengthen public health policies according to established international priorities. Monitoring parliamentary interventions has proven to be a valid tool for evaluating patterns of political debate and decisions on diabetes (AU)

Métodos: Búsqueda sistemática de las iniciativas parlamentarias (1979-2010) en la página web del Congreso de los Diputados, usando la palabra clave «diabetes». Estudio descriptivo de la frecuencia de lasiniciativas, y análisis de contenido, según las prioridades de la Organización Mundial de la Salud (OMS),la Federación Internacional de Diabetes y la Federación Española de Diabetes. Otras variables: año depresentación, legislatura, tipo de iniciativa y decisión política (sí/no). Resultados: Hubo 59 iniciativas, el 22% relacionadas con las primeras internacionales y un 44,1% las dosúltimas legislaturas como respuesta al programa Diabetes Action Now de la OMS. Un 32,2% estuvieronrelacionadas con programas sociales y educativos, y un 23,7% con recursos y acceso a los servicios desalud. La mayoría (74,6%) fueron preguntas de control al gobierno, que sólo requieren respuesta y noaprobación/desaprobación. De las 15 iniciativas que requerían decisión, ocho fueron aprobadas. Conclusiones: Los legisladores españoles han tenido en cuenta los estándares internacionales. Sinembargo, la toma de decisiones a veces ha sido lenta, aunque es importante tener en cuenta que lamayoría de las responsabilidades políticas relacionadas con la salud están transferidas a las comunidadesautónomas. Las estrategias nacionales sobre diabetes requieren fortalecer las políticas en salud públicaconsiderando las prioridades internacionales sobre el tema. Monitorizar las iniciativas parlamentarias esuna herramienta para evaluar el debate político y las decisiones tomadas sobre la diabetes (AU)

The parliamentary political agenda: a tool for policy analysis of diabetes priorities in Spain.

OBJECTIVE: To analyze the political agenda on diabetes in Spain under democracy by considering the frequency and content of initiatives in the Spanish parliament. METHODS: A systematic search of parliamentary interventions (1979-2010) reported on the Spanish Congress of Deputies' web page was carried out using the key word "diabetes". A descriptive study of the frequency of interventions was performed, followed by a content analysis, according to the priorities of the World Health Organization (WHO), the International Diabetes Federation and the Spanish Diabetes Federation. Other study variables were the year of presentation, legislature, type of initiative and whether a political decision was taken (yes/no). RESULTS: There were 59 interventions: 22% were related to the first international initiatives and 44.1% took place in the last two legislatures in response to the WHO's program Diabetes Action Now. A total of 32.2% of the initiatives addressed educational and social programs, while 23.7% addressed access to resources and health services. Most initiatives (74.6%) consisted of parliamentary questions to the government, which only required a response. Of the 15 initiatives requiring a decision to be taken, only eight were approved. CONCLUSIONS: Spanish legislators aim to comply with international standards. Nevertheless, political decision-making has sometimes been slow. Importantly, most of the political responsibilities related to health have been transferred to the autonomous regions. The updated National Diabetes Strategy in Spain will need to strengthen public health policies according to established international priorities. Monitoring parliamentary interventions has proven to be a valid tool for evaluating patterns of political debate and decisions on diabetes.

Incidence of overweight and obesity in a Mediterranean population-based cohort: the Cornellà Health Interview Survey Follow-up Study (CHIS.FU).

OBJECTIVE: To study the changes in body mass index (BMI) in a population-based cohort and their relationship with sociodemographic variables in a Mediterranean-country. METHOD: A prospective population-based cohort with 8-year follow-up. The data used derive from the Cornellà-Health-Interview Survey Follow-up (CHIS.FU). 1008 people aged > or = 20 years (females=508; males=500) were interviewed in 1994 and in 2002, providing self-reported weight and height data. The BMI was compared using the Wilcoxon test for paired data. Changes in the BMI were calculated and their relationship with sociodemographic-variables and lifestyles using multivariate Breslow-Cox regression. RESULTS: 28.1% of participants had changed from normal-BMI in 1994 to overweight in 2002 (women=25.6%; men=31.6%). 16.8% increased from overweight to obesity (women=25.8%; men=11.2%). The cumulative incidence of overweight: women=26.4%; men=34.0%. The cumulative incidence of obesity: women=29.9%; men=13.1%. The cumulative age and sex-adjusted incidence of overweight showed a significant relationship with marital-status (married: RR=2.0; 95% CI: 1.2-3.4, divorced/widowed: RR=4.0; 95% CI: 1.7-9.3) and moderate alcohol-consumption (RR=1.86; 95% CI: 1.1-3.1). We observed a decreased age-adjusted risk in the incidence of obesity for men (RR=0.49; 95% CI: 0.3-0.8). CONCLUSION: The observed changes in the increase in the incidence of obesity and overweight indicated a similar evolution in the obesity epidemic regardless of Mediterranean dietary patterns in our population.

[Relationship in Spain of the length of the gestation and the birth weight with mother's nationality during the period 2001-2005]. / Relación en España de la duración de la gestación y del peso al nacer con la nacionalidad de la madre durante el período 2001-2005.

BACKGROUND: Association between immigration and low birth weight (LBW) and preterm birth (PB) is an important indicator of health inequalities. The objective of this study is to analyse the differences between LBW and PB according to the mothers nationality in newborns in Spain. METHODS: Data were provided from the National Statistical Bulletin of Birth of 1,878,718 newborns in the period 2001-2005. The nationality was considered the exposure variable (Spanish- Immigrant). The outcomes were LBW (< 2,500 gr and >or=37 gestational weeks) and PB (< 37 gestational weeks). Odds ratios were calculated and adjusted by possible confounders by logistic regression. RESULTS: PB and LBW prevalence were higher in Spanish women (7.9% and 3.2% respectively). In comparison with Spanish ones, the lowest risk of PB was observed in North Africa (ORa= 0.77 CI95% 0.74-0.80). With respect to LBW, the lowest risk was found in mothers from South America (ORa=0.62 CI95% 0.59-0.65) and Eastern Europe (ORa=0.65 CI95% 0.60-0.71). CONCLUSION: Results of LBW and PB were more favourable in the births of immigrant women. It could be associated with the healthy migrant effect and a low frequency of risk practices during gestation.

Relación en España de la duración de la gestación y del peso al nacer con la nacionalidad de la madre durante el período 2001-2005 / Relation-ship in Spain of the length of the gestation and the birth weight with mother’s nationality during the period 2001-2005

Fundamento: La asociación de la inmigración con el bajo peso al nacimiento (BP) y el parto pretérmino (PP) es un importante indicador de inequidades en salud. El objetivo de este estudio es analizar las diferencias entre BP y el PP según la nacionalidad de la madre. Métodos: Los datos proceden del Boletín Estadístico de Nacimientos. Durante el período de estudio hubo 1.878.718 recién nacidos. La nacionalidad fue considerada como variable de exposición (española-inmigrante). Las variables de efecto son BP (nacimientos de 37 o más semanas de gestación con un peso inferior a 2.500 gramos) y PP (recién nacidos con menos de 37 semanas de gestación). Se calcularon odds ratios simples y ajustadas por posibles variables de confusión mediante regresión logística. Resultados: La prevalencia de BP y PP entre las mujeres españolas fue de 7,9% y 3,2% respectivamente, mientras que en las extranjeras fue de 7,3% y 2,4% respectivamente. En comparación con las españolas, el riesgo más bajo de PP lo presentaron las mujeres procedentes de África del Norte (ORa= 0,77 IC95%0,74-0,80). Con respecto al BP el riesgo más bajo se observó en madres de Sudamérica (ORa=0,62 IC95%0,59-0,65) y Europa del Este (ORa=0,65 IC95%0,60- 0,71). Conclusión: Los recién nacidos de madre extranjera presentan menos riesgo de BP y PP que los autóctonos, posiblemente como consecuencia del sesgo por la condición de ser inmigrante sano y por la menor frecuencia de prácticas de riesgo durante la gestación de las mujeres inmigrantes (AU)

Policy options for obesity in Europe: a comparison of public health specialists with other stakeholders.

OBJECTIVE: To explore policy options that public health specialists (PHS) consider appropriate for combating obesity in Europe, and compare their preferences with those of other stakeholders (non-PHS). DESIGN: Structured interviews using multicriteria mapping, a computer-based, decision-support tool. SETTING: Nine European countries. SUBJECTS: A total of 189 stakeholders. Twenty-seven interviewees were PHS and non-PHS included food, sports and health sectors. MEASUREMENTS: A four-step approach was taken, i.e. selecting options, defining criteria, scoring options quantitatively and weighting the criteria to provide overall rankings of options. Interviews were recorded and transcribed to yield qualitative data. RESULTS: The PHS concur with other stakeholders interviewed, as all emphasised the importance of educational initiatives in combating obesity, followed by policies to improve community sports facilities, introduce mandatory food labelling and controlling food and drink advertising. Further analyses revealed several significant differences. The non-PHS from the private sector ranked institutional reforms favourably; the PHS from non-Mediterranean countries supported the option of medicines to prevent obesity; and those PHS from Mediterranean countries endorsed the use of activity monitoring devices such as pedometers. As far as appraisal criteria were concerned, PHS considered efficacy and the economic impact on the public sector to be the most important. CONCLUSION: There is clear consensus among PHS and other stakeholders concerning the need for a package of policy options, which suggests that European-wide implementation could be successful. However, it would be advisable to avoid more contentious policy options such as taxation until future changes in public opinion.
