Family influence on the consumption of sugary drinks by children under two years old / Influência familiar no consumo de bebidas açucaradas em crianças menores de dois anos

ABSTRACT OBJECTIVE To evaluate the influence of family habits and household characteristics on the consumption of sugary drinks by Brazilian children under two years old. METHODS This was a cross-sectional study that used secondary data generated by the National Health Survey (PNS) in 2013. We studied 4,839 pairs of children under two years old and adults living in the same house. We estimated the prevalence of the indicator of sugary drinks consumption for the total sample of children and according to family and household variables. We applied multiple logistic regression analysis to evaluate the influence of family habits and household characteristics on the consumption of sugary drinks by the children. RESULTS The consumption of sugary drinks was identified in 32% of the studied children (95%CI 30.6-33.3) and was independently associated with the following family and household characteristics: regular consumption of sugary drinks by the adult living in the house (OR = 1.78; 95%CI 1.51-2.10), watching TV for more than three hours per day (OR = 1.22; 95%CI 1.03-1.45), older age (OR = 3.10; 95%CI 1.54-6.26), greater education level (OR = 0.70; 95%CI 0.53-0.91), house located in the Northeast region (OR = 0.65; 95%CI 1.54-6.26), and number of family members (OR = 1.05; 95%CI 1.00-1.09). CONCLUSIONS Our findings indicate the high prevalence of sugary drinks consumption by Brazilian children under two years old and show that sociodemographic characteristics and family habits affect this feeding practice not recommended in childhood.

Consumption of sugar-rich food products among Brazilian students:National School Health Survey (PeNSE 2012) / Consumo de alimentos ricos em açúcar entre estudantes brasileiros:Pesquisa Nacional de Saúde do Escolar (PeNSE 2012) / Consumo de alimentos ricos en azúcar entre estudiantes brasileños:Encuesta Nacional de Salud Escolar (PeNSE 2012)

Abstract This study aimed to analyze the consumption of high-sugar foods by Brazilian schoolchildren and to identify associated factors, based on data from the National School Health Survey (PeNSE 2012). Consumption of these foods was classified as: do not consume sweets and soft drinks regularly; consume sweets or soft drinks regularly; and consume sweets and soft drinks regularly. Its association with sociodemographic information, eating habits, and family contexts were investigated via multiple ordinal regressions. Regular consumption of sweets and/or soft drinks was reported by 19.2% and 36.1% of adolescents, respectively, and higher prevalence was associated with female gender, age 14-15 years, higher maternal education, not living with the mother and father, not eating meals with the parents, eating while watching TV, and longer TV time. Nearly one-fifth of adolescents regularly consumed sweets and soft drinks, which was associated with socio-demographic and behavioral factors that should be targeted in order to improve their food consumption.

Resumo Objetivou-se analisar o consumo de alimentos ricos em açúcar entre estudantes brasileiros e identificar seus fatores associados. Utilizaram-se dados da Pesquisa Nacional de Saúde do Escolar (PeNSE 2012). O consumo desses alimentos foi classificado como: não consomem guloseimas/refrigerantes regularmente; consomem guloseimas ou refrigerantes regularmente; consomem guloseimas e refrigerantes regularmente. Fatores sociodemográficos, alimentares e familiares associados foram avaliados por regressão ordinal múltipla. O consumo regular de guloseimas e/ou refrigerantes foi relatado por 19,2% e 36,1% dos adolescentes, respectivamente, sendo mais prevalente entre estudantes do sexo feminino, com 14-15 anos de idade, com maior escolaridade materna, que não viviam com a mãe e o pai, que não realizam as refeições com os pais, que comiam assistindo TV e que passavam mais tempo diante da TV. Quase 1/5 dos adolescentes consumia guloseimas e refrigerantes regularmente, condição associada a fatores sociodemográficos e comportamentais, os quais devem ser priorizados visando a melhorar seu consumo alimentar.

Resumen Se tuvo como objetivo analizar el consumo de alimentos ricos en azúcar entre estudiantes brasileños e identificar sus factores asociados. Se utilizaron datos de la Encuesta Nacional de Salud Escolar (PeNSE 2012). El consumo de estos alimentos fue clasificado como: no consumen golosinas/refrescos regularmente; consumen golosinas o refrescos regularmente; consumen golosinas y refrescos regularmente. Factores sociodemográficos, alimentarios y familiares asociados fueron evaluados por regresión ordinal múltiple. El consumo regular de golosinas y/o refrescos fue relatado por 19,2% y 36,1% de los adolescentes, respectivamente, siendo más prevalente entre estudiantes del sexo femenino, con 14-15 años de edad, con mayor escolaridad materna, que no vivían con la madre y el padre, que no realizan las comidas con los padres, que comían viendo TV y que pasaban más tiempo viendo TV. Casi 1/5 de los adolescentes consumía golosinas y refrescos regularmente, condición asociada a factores sociodemográficos y de comportamiento, que deben ser observados como prioridad para mejorar el consumo alimenticio.

Cambios en el consumo aparente de lácteos, bebidas azucaradas y jugos procesados en el Gran Santiago. Chile. 1987-2007: Changes in the consumption of dairy products, sugary drinks and processed juices in the Chilean population

Background: Nowadays, Chilean population tends to replace or eat a lower amount of food with health protective properties and a higher proportion of unhealthy foodstuff. Aim: To describe and compare the intake of dairy products, sugary drinks and processed juices among Chileans. Material and Methods: An analysis of data compiled from the Survey on Household Budget and Expenses carried out by the Chilean National Institute of Statistics (INE), using a representative sample of households. The sample was surveyed between 1987 and 2007. The analysis was performed for all households surveyed and for households belonging to the second (highest incomes) and fifth quintile (lowest incomes). The Chilean Food Guide and the international recommendations of the Institute of Medicine of the United States and the American Heart Association (in the case of sugars) were used as reference. Results: Even though the intake of dairy products increased during the period of the survey, it was lower than the intake of sugary drinks and juices, which increased. Also, calcium recommendations were not covered. On the other hand, the intake of added sugars increased to figures over current recommendations. Conclusions: The intake of dairy products and calcium is below the recommended amounts established by international organisms, and added sugars intake is greater than the advisable levels recommended by international organisms.

Palatabilizantes em dietas de leitões recém-desmamados / Flavors in diets for weanling pigs

Com o intuito de verificar a eficácia do açúcar e do edulcorante à base de sacarina sódica e neoesperidina nas dietas de leitões, foram realizados dois experimentos, ambos com 42 leitões recém-desmamados aos 21 dias de idade. Foram oferecidas três dietas: dieta controle (DC), dieta com açúcar (DA) e dieta com edulcorante (DE). Os experimentos foram em blocos ao acaso, sendo o primeiro com sete repetições e dois animais por unidade experimental e o segundo com seis repetições, um animal por unidade experimental, e arranjo fatorial 3 x 2 + 1 (três dietas, duas épocas de abate: aos 28 e 35 dias de idade e um abate no dia do desmame). No primeiro experimento, os animais permaneceram nas instalações de creche até 63 dias de idade para avaliação do desempenho e da viabilidade econômica das dietas. No segundo experimento, os animais foram abatidos para se proceder à pesagem de órgãos, medição do comprimento do intestino delgado e coleta dos segmentos do duodeno e jejuno para realização da morfometria intestinal. Não houve diferenças entre as dietas para consumo diário de ração (CDR), ganho diário de peso (GDP) e conversão alimentar (CA) nos períodos 1 (21 aos 28 dias), 3 (21 aos 50 dias) e 4 (21 aos 63 dias de idade). No período 2 (21 aos 35 dias), os animais que consumiram a DE apresentaram maior (P<0,05) CDR e GDP, se comparados aos que consumiram a DA. Nos períodos 1, 2 e 3, foi observado menor custo da dieta por kg de peso vivo ganho e melhores índices econômico e de custo para os animais que consumiram DE. Ao se avaliar a morfometria intestinal e o peso de órgãos, não se observou diferença entre as dietas, com exceção para o peso do estômago, que foi maior nos animais que consumiram DE. A inclusão de edulcorante é eficaz em melhorar o desempenho no período 2, além de ser viável sob o ponto de vista econômico...

In order to verify the effectiveness of sugar and sweeteners containing saccharin and neohesperidin in diets of piglets, two experiments were conducted, both with 42 newborn piglets weaned at 21 days old. Were offered three diets: control diet (DC), diet with sugar (DA) and diet with sweetener (DE). The experiments were done in randomized blocks, the first of which had seven replicates and two animals per experimental unit and the second, six replicates and one animal per experimental unit comprising a factorial 3 x 2 + 1 design (three diets, two slaughter ages: at 28 and 35 days of age and slaughter on the day of weaning). In the first experiment, the animals remained in the nursery facilities until 63 days of age to evaluate the performance and the economic viability of the diets. In the second experiment, the animals were slaughtered to weigh the organs, measure the length of the small intestine and collect segments of the duodenum and jejunum to determine intestinal morphology. There were no differences between diets for the average dairy feed intake (ADFI), average dairy gain (ADG) and gain:feed (G:F) in Periods 1 (21 to 28 days), 3 (21 to 50 days) and 4 (21 to 63 days old). In Period 2 (21 to 35 days), animals that consumed DE had higher (P<0.05) ADFI and ADG, compared to those fed the DA. In Periods 1, 2 and 3 a lower cost per kg of the diet of live weight gain and better economic indicators for the animals fed DE were observed. No differences were observed between the diets when evaluating intestinal morphology and organ weights, except for the weight of the stomach, which was higher in animals fed DE. The inclusion of sweetener is effective in improving performance in Period 2, and is viable under the economical point of view...

OBJECTIVE To test the efficacy of nutritional guidelines for school lunch cooks aiming to reduce added sugar in school meals and their own sugar intake. METHODS A controlled randomized cluster trial was carried out in twenty public schools in the municipality of Niteroi in Rio de Janeiro, Southeastern Brazil, from March to December 2007. A nutrition educational program was implemented in the schools in question through messages, activities and printed educational materials encouraging reduced levels of added sugar in school meals and in the school lunch cooks’ own intake. The reduced availability of added sugar in schools was evaluated using spreadsheets including data on the monthly use of food item supplies. The cooks’ individual food intake was evaluated by a Food Frequency Questionnaire. Anthropometric measurements were taken according to standardized techniques and variation in weight was measured throughout the duration of the study. RESULTS There was a more marked reduction in the intervention schools compared to the control schools (-6.0 kg versus 0.34 kg), but no statistically significant difference (p = 0.21), although the study power was low. Both groups of school lunch cooks showed a reduction in the consumption of sweets and sweetened beverages, but the difference in sugar intake was not statistically significant. Weight loss and a reduction in total energy consumption occurred in both groups, but the difference between them was not statistically significant, and there was no alteration in the percentages of adequacy of macronutrients in relation to energy consumption. CONCLUSIONS The strategy of reducing the use and consumption of sugar by school lunch cooks from public schools could not be proved to be effective. .

Alveolar wound healing in rats fed on high sucrose diet / Alveolar wound healing in rats fed on high sucrose diet.

The potential for bone repair is influenced by various biochemical, biomechanical, hormonal, and pathological mechanisms and factors such as diet and its components, all of which govern the behavior and function of the cells responsible for forming new bone. Several authors suggest that a high sucrose diet could change the calcium balance and bone composition in animals, altering hard tissue mineralization. The mechanism by which it occurs is unclear. Alveolar healing following tooth extraction has certain characteristics making this type of wound unique, in both animals and humans. The general aim of this study was to evaluate and quantify the biological response during alveolar healing following tooth extraction in rats fed on high sucrose diets, by means of osteocyte lacunae histomorphometry, counting empty lacunae and measuring areas of bone quiescence, formation and resorption. Forty-two Wistar rats of both sexes were divided into two groups: an experimental group fed on modified Stephan Harris diet (43

sucrose) and a control group fed on standard balanced diet. The animals were anesthetized and their left and right lower molars extracted. They were killed at 0 hours, 14, 28, 60 and 120 days. Samples were fixed, decalcified in EDTA and embedded in paraffin to prepare sections for optical microscopy which were stained with hematoxylin/eosin. Histomorphometric analysis showed significant differences in the size of osteocyte lacunae between groups at 28 and 60 days, with the experimental group having larger lacunae. There were more empty lacunae in the experimental group at 14 days, and no significant difference in the areas of bone activity. A high sucrose diet could modify the morphology and quality of bone tissue formed in the alveolus following tooth extraction.

Added sugars: consumption and associated factors among adults and the elderly. São Paulo, Brazil / Açúcares de adição: consumo e fatores associados entre adultos e idosos. São Paulo, Brasil

OBJECTIVE: To investigate added sugar intake, main dietary sources and factors associated with excessive intake of added sugar. METHODS: A population-based household survey was carried out in São Paulo, the largest city in Brazil. Cluster sampling was performed and the study sample comprised 689 adults and 622 elderly individuals. Dietary intake was estimated based on a 24-hour food recall. Usual nutrient intake was estimated by correcting for the within-person variance of intake using the Iowa State University (ISU) method. Linear regression analysis was conducted to identify factors associated with added sugar intake. RESULTS: Average of energy intake (EI) from added sugars was 9.1% (95% CI: 8.9%; 9.4%) among adults and 8.4% (95% CI: 8.2%; 8.7%) among the elderly (p < 0.05). Average added sugar intake (% EI) was higher among women than among men (p < 0.05). Soft drink was the main source of added sugar among adults, while table sugar was the main source of added sugar among the elderly. Added sugar intake increased with age among adults. Moreover, higher socioeconomic level was associated with added sugar intake in the same group. CONCLUSIONS: Added sugar intake is higher among younger adults of higher socioeconomic level. Soft drink and table sugar accounted for more than 50% of the sugar consumed.

OBJETIVO: Avaliar o consumo alimentar, principais fontes dietéticas e fatores associados à ingestão acima da recomendação de açúcares de adição. MÉTODOS: Um inquérito populacional domiciliar foi realizado em São Paulo, a maior cidade do Brasil. A população de estudo foi obtida por um processo de amostragem por conglomerados e composta por 689 adultos e 622 idosos. O consumo alimentar foi estimado por um recordatório de 24 horas. Os valores nutricionais foram ajustados pela variância intra pessoal, utilizando o método instituído pela Universidade de Iowa (ISU). A regressão linear foi conduzida para identificar os fatores associados ao consumo de açúcares de adição s. RESULTADOS: A média de energia proveniente dos açúcares de adição foi de 9,1% (IC 95%: 8,9%; 9,4%) entre adultos e 8,4% (IC 95%: 8,2%; 8,7%) entre idosos (p < 0,05). A média do consumo de açúcares de adição foi maior entre mulheres quando comparada à dos homens (p < 0,05). A principal fonte de açúcares de adição foi refrigerante entre adultos, enquanto que entre idosos foi açúcar de mesa. O consumo de açúcares de adição aumentou conforme a idade entre adultos. Além disso, o alto nível socioeconomico esteve associado com o consumo de açúcares de adição entre adultos. CONCLUSÕES: O consumo de açúcares de adição é maior entre adultos de nível socioeconômico alto. Refrigerantes e açúcares de mesa são responsáveis por mais de 50% do consumo de açúcares.

Feeding and oral hygiene habits of children attending daycare centres in Bangalore and their caretakers oral health knowledge, attitude and practices.

Aim: Caretakers in day-care centers play a significant role in imparting good oral hygiene practices and also extend a working relationship with parents with regard to their children's oral health. As a result of this, caregiver's dental knowledge, attitudes, beliefs and practices affect the child's oral condition. Settings and Design: A descriptive cross-sectional study involved caretakers working in day-care centers of Bangalore. Fifty-two day-care centers were randomly selected from the different zones of Bangalore city, from which 246 caretakers provided consent for participation. Materials and Methods: A comprehensive, closed-ended, self-administered questionnaire was employed which was designed to collect the sociodemographic details and to evaluate the oral health knowledge, attitudes, practice of caretakers. The institutional review committee approved the study. Data were entered using SPSS 13.01. Results: Seventy-nine percent of the subjects had good knowledge of child's tooth eruption time, clinical presentation of dental caries and the role of fluoride in caries prevention. Yet, half of the subjects found routine dental examination after all the milk teeth have erupted in the oral cavity insignificant and 41% strongly agreed that dentist should be consulted only when the child has a toothache. In spite of the good knowledge, 77% preferred to use pacifier dipped in honey/sugar if the children acted troublesome. Analogous to this, 45% gave milk/juice with sugar before the child's nap time. Conclusions: The results of this study indicate that caretaker's attitude toward oral health care needs is far from acceptable standards to mirror any positive impact on the children.

Using zero inflated models to analyze dental caries with many zeroes.

Aim: The study aimed to analyze and determine the factors associated with dental caries experience contains many zeros by zero inflated models. Design: A cross sectional design was employed using clinical examination and questionnaire with interview method. Materials and Methods: A study was conducted during March-August 2007 in Dharwad, Karnataka, India, involved a systematic random samples of 1760 individuals aged 18-40 years. The dental caries examination was carried out by using DMFT index (i.e. Decayed (D), Missing (M), Filled (F)). The DMFT index data contains many zeros were analyzed with Zero Inflated Poisson (ZIP) and Zero Inflated Negative Binomial (ZINB) models. Results: The study findings indicated, the variables such as family size, frequency of brushing and duration of change of toothbrush were positively associated with dental caries. But the variable the frequency of sweet consumption is negatively associated with dental caries experience in Zero Inflated Poisson (ZIP) and Zero Inflated Negative Binomial (ZINB) models. Conclusions: The ZIP model is a very good fit over the standard Poisson model and the ZINB is the better statistical fit compared to the Negative Binomial model. The Zero Inflated Negative Binomial model is better fit over the Zero Inflated Poisson model for modeling the DMF count data.

Cambios en el consumo aparente de nutrientes en el Gran Santiago 1988-1997 en hogares según ingreso y su probable relación con patrón de enfermedades crónicas no transmisibles / Changes in household food and nutrient consumption in Metropolitan Santiago 1988-97 by income

Background: The rise in the prevalence of obesity, diabetes, and other risk factors for cardiovascular diseases and cancer observed in Chile over the past decades may be related to changes in dietary patterns of the population. Aim: To report changes in household apparent food-nutrients consumption (HAFNC) for Metropolitan Santiago-Chile 1988-97. Material and Methods: The analysis is based on data from household expenditure surveys conducted by the Instituto Nacional de Estadísticas (INE) on a representative sample of the population to define changes in food prices. Information on food and drink purchases were grouped by specific items and expen-ditures standardized across the two surveys. HAFNC was determined based on unit consumed at home and out of home by the total group and by income quintile using national food composition tables. Results: Apparent energy consumption increased over the study period by 25 percent, this was mainly explained by increased consumption of meat and dairy (rich in saturated fats of animal origin) and of processed foods (fat spreads, sweets and pastries) and foods rich in added sugars (sugary drinks and juices). Dietary fiber derived from whole grains, legumes and cereals decreased. The HAFNC of items protective against nutrition related chronic diseases, such as vegetables, fruits and other fiber rich foods remained stable or frankly decreased (legumes and non-starchy vegetables) Fish and other marine foods rich in omega- 3 fats remained low. Conclusions: The changes in apparent food consumption patterns can be characterized by an increase in energy dense, fat and sugar rich foods with a low consumption of fi sh, whole grains, legumes, vegetables and fruits.

Sugar-sweetened beverages consumption and BMI in Mexican adolescents: Mexican National Health and Nutrition Survey 2006 / Consumo de bebidas azucaradas y su relación con el IMC en adolescentes mexicanos: Encuesta Nacional de Salud y Nutrición 2006

OBJECTIVE: To evaluate the association between the consumption of sugar-sweetened beverages (SSBs) and body mass index (BMI) in Mexican adolescents. MATERIAL AND METHODS: We analyzed the data of 10 689 adolescents (ages 10 to 19 years old) who participated in the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006). Consumption of SSBs (i.e. sodas, fruit beverages and sugar beverages) was evaluated by means of a semi-quantitative food frequency questionnaire. BMI was calculated (kg/m²). RESULTS: Mean age was 13.8 ± 2.7 years. Fifty percent were females. Mean BMI was 21.7 ± 4.5. Thirty percent of adolescents were overweight or obese. Ninety percent of adolescents consumed at least one SSB during the 7 days before the interview. The median consumption of SSBs was 0.89 portion per day. Multiple-linear regression analysis showed that for each portion of sodas consumed, a 0.17-point increase in BMI was observed in boys after adjusting for confounders (95 percent CI; 0.02-0.32, p 0.03). Positive interactions of SSB consumption with age and time watching TV were observed in boys. CONCLUSIONS: Consumption of sodas was positively associated with BMI in Mexican boys.

OBJETIVO: Examinar la asociación entre el consumo de bebidas refrescantes azucaradas (BRA) y el índice de masa corporal (IMC) en adolescentes mexicanos. MATERIAL Y MÉTODOS: Se analizaron datos de 10 689 adolescentes (10 a 19 años de edad) de la Encuesta Nacional de Salud y Nutrición 2006 (ENSANUT 2006). El consumo de bebidas refrescantes azucaradas (BRA: refrescos, bebidas de fruta y bebidas endulzadas) se evaluó con un cuestionario semicuantitativo de frecuencia de consumo de alimentos. Se calculó el índice de masa corporal (kg/m²). RESULTADOS: La media de edad fue de 13.8 ± 2.7 años. El 50.4 por ciento fueron mujeres. La media de IMC fue de 21.7 ± 4.5. Un 30 por ciento de los adolescentes presentó sobrepeso u obesidad. El 90 por ciento de los adolescentes consumieron al menos una BRA en los 7 días previos a la encuesta, con una mediana de 0.89 porciones/día. El análisis de regresión lineal mostró que por cada porción consumida de refrescos, el IMC en los adolescentes varones aumentó 0.17 unidades, después de ajustar por variables confusoras (IC 95 por ciento: 0.02, 0.32, p= 0.03). Se observaron interacciones entre el consumo de BRA con la edad y el tiempo viendo televisión en los varones adolescentes. CONCLUSIONES: El consumo de refrescos se asoció positivamente con el IMC en varones adolescentes mexicanos.

Oral health-related KAP among 11- to 12-year-old school children in a government-aided missionary school of Bangalore city.

BACKGROUND: To organize community-oriented oral health promotion programs systematic analysis of the oral health situation would be needed, including information on oral health knowledge, attitudes, and practices (KAP). AIM: The aim of this study was to assess knowledge, attitude, and practice (KAP) toward oral health among 11 to 12-year-old school children in a government-aided missionary school of Bangalore city. MATERIALS AND METHODS: The study group comprised of 212 children (Male: 108; Female; 104) who were in the age group of 11-12 years studying in a government-aided missionary school of Bangalore city. Data on oral health KAP were collected by means of a self-administered questionnaire. Statistical significance was determined by Chi-square test. RESULTS: This survey found that only 38.5% of the children brush their teeth two or more times a day. Pain and discomfort from teeth (35.1%) were common while dental visits were infrequent. Fear of the dentist was the main cause of irregular visit in 46.1% of study participants. High proportion of study participants reported having hidden sugar at least once a day: soft drinks (32.1%), milk with sugar (65.9%), and tea with sugar (56.1%). It was found that 5.4% and 3.9% of study participants smoke and chew tobacco, respectively. CONCLUSION: Results of this study suggest that oral health KAP of study participants are poor and needs to be improved. Systematic community-oriented oral health promotion programs are needed to improve oral health KAP of school children.

Reliability of a sugar consumption questionnaire for rural Haiti

OBJECTIVE: Studies of dental caries should account for sugar consumption as a potential confounder or effect modifier of other exposure-caries associations. The purpose of this study was to assess the reliability of a sugar consumption score for rural Haiti through correlation of test-retest scores derived from a structured, interviewer-administered questionnaire. METHODS: A structured, interviewer-administered questionnaire of sugar consumption was developed for rural Haiti to achieve contextual validity. The resulting questionnaire had two parts; one part captures the child's consumption of sugar products frequency; the second part captures sugar additions to the child's food preparation. A test-retest, one week apart, was conducted on a sample of 30 mother-child pairs (children ages 9-17). Test-retest correlations and paired t-testing was conducted to assess the questionnaire's reliability. RESULTS: All test-retest (Part 1, children's questions; Part 2, mother's questions; the combined scores) had Pearson product correlation coefficients of 0.7 or greater, respectively. All test-retest scores had paired t-test p-values3 0.95. CONCLUSIONS: A reliable, contextually valid relative sugar consumption questionnaire specific for rural Haiti is presented. The questionnaire and methodology employed in its development and testing may have utility for dental caries researchers in investigations in less developed countries.

Estratégias para prevenção da obesidade em crianças e adolescentes / Strategies for obesity prevention in children and adolescents

Poucos estudos obtiveram resultados favoráveis na prevenção da obesidade. Teoricamente, crianças e adolescentes, se comparados aos adultos, poderiam mais facilmente prevenir o ganho excessivo de peso, pois estão crescendo e têm maior possibilidade de gastar energia em atividades de lazer. Entretanto, não se consegue superar os muitos fatores que concorrem para a crescente epidemia de obesidade e as intervenções na sua maioria abordam uma fração muito pequena dos fatores que geram a obesidade. Aspectos importantes, como o papel da indústria de alimentos, das cadeias de fast food, das propagandas, de um estilo de vida que mantêm as crianças cada vez mais sedentárias e submetidas a um hiperconsumo calórico, não têm espaço nos desenhos de estudos tradicionais. Das intervenções publicadas, as que integram a família no tratamento têm obtido melhores resultados. Estudos com elementos isolados da dieta como cálcio, proteína, fibras e índice glicêmico não têm mostrado eficácia, e embora não conclusivos, os resultados referentes à redução de bebidas com alto teor de açúcar e redução do sedentarismo são promissores.

Few studies on treatment or prevention of obesity have shown significant results. Theoretically, in children and adolescents as compared to adults, prevention of excessive weight gain should be easy due to the energy expended during growth, associated with more time spent in leisure-time activities. However, numerous factors that stimulate overeating and sedentary behaviors are difficult to overcome. Additionally, most intervention studies have focused on a minor portion of the many factors associated with obesity. Important aspects of the obesity epidemic such as the role of the food industry, fast food chains, advertising, and a lifestyle that limits children to sedentary activities and overeating cannot be explored by a traditional clinical trial design. At any rate, among the published interventions, those including the family in weight-reduction strategies have shown the best results, as compared to children-centered approaches. Meanwhile, studies on specific nutrient or dietary composition (such as calcium, protein, or glycemic index) related to prevention or treatment of obesity have failed to yield good results. Reducing the intake of high-sugar carbonated drinks and juices has shown promising but still inconclusive results.

Epidemiology of dental caries in Chandigarh school children and trends over the last 25 years.

The prevalence of dental caries in 6, 9, 12 and 15-year-old school children of Chandigarh, selected on a randomized basis was evaluated using Moller's criteria (1966) and correlated with the various risk factors. The mean deft was found to be 4.0 +/- 3.6 in 6 year old and 4.61 +/- 3.14 in 9 year old, whereas the mean DMFT in 12 and 15 year old was found to be 3.03 +/- 2.52 and 3.82 +/- 2.85 respectively. The high prevalence of dental caries in these children was attributed to the lack of use of fluoride toothpaste (80% children), lack of knowledge about etiology of dental caries (98%) and frequency of sugar exposures up to more than five times per day (30%).

Do autistic children have higher levels of caries? A cross-sectional study in Turkish children.

The aim of this study is to assess whether the dental caries experience is higher in children with an autistic disorder (AD) than in normal children. Three schools for autistic children and three standard elementary schools in Istanbul, Turkey, were included in a cross-sectional study. Subjects were orally examined. Socio-demographic information and data about their oral care habits were obtained from their parents from records. Sixty-two children with AD and 301 children without AD were examined. Their ages varied between 6 and 12 years. Children with AD compared to those without AD had lower experience of caries. Logistic regression analysis of DMFT showed that the dental status was positively affected in younger children (OR = 15.57; 95% CI 7.62, 31.80), children from families with high income (OR = 5.42; 95% CI 2.31, 12.75), children brushing teeth regularly (OR = 2.01, 95% CI 1.10, 3.68), children consuming less sugar (OR = 5.01; 95% CI 2.57, 9.76) and in those with AD (OR=3.99; 95% CI 1.56, 10.19). Children with AD had better caries status than children without AD at younger ages.

Introdução da sacarose no plano alimentar de portadores de diabetes mellitus tipo 1: sua influência no controle glicêmico / Introduction of sucrose in the diet plan of persons with type 1 diabetes: its influence in the glycemic control

Para avaliar a influência da introdução da sacarose no controle glicêmico, dez adolescentes com diabetes tipo 1 foram acompanhados durante oito meses. Inicialmente, receberam orientação individualizada sobre dieta, automonitorização da glicemia, ajuste da dose de insulina e, a partir do quarto mês, iniciou-se a introdução de alimentos com sacarose, através da técnica de contagem de gramas de carboidratos, no lanche vespertino. O colesterol total e triglicérides foram dosados no início e no final do estudo e a hemoglobina A1C no início, após quatro meses sem e após quatro meses com consumo de sacarose. Todos os participantes apresentaram desenvolvimento puberal e crescimento adequados; dois possuíam sobrepeso e os demais eram eutróficos. A freqüência da automonitorização diminuiu após quatro meses de acompanhamento (p< 0,001). Os valores de colesterol total e triglicérides estiveram dentro da normalidade e os valores da A1C diminuíram durante o seguimento (p= 0,027). Conclusão: o consumo de alimentos com sacarose, utilizando a técnica de contagem de gramas de carboidratos, não comprometeu o controle metabólico dos adolescentes com diabetes tipo 1.
