New Zealand household purchases of sugar-sweetened, artificially sweetened, and unsweetened beverages: 2015-2019

OBJECTIVE

To assess annual household purchases of sugar-sweetened beverages (SSBs), artificially sweetened beverages (AFSBs), and unsweetened beverages (USBs) by household composition and income, and over time.

DESIGN

Observational cohort study using beverage purchasing data linked to a supermarket database. ANOVA was used to compare total household purchase volumes (L) and the contribution of beverages purchased by category, household composition (size), household income (four categories from New Zealand (NZ) < $30 000 to > $90 000), and over time (trend from 2015 to 2019).

SETTING

Aotearoa NZ.

PARTICIPANTS

∼1800 households in the NielsenIQ Homescan® market research panel.

RESULTS

In 2019, the mean (sd) annual household purchase volume and relative contribution to total beverage volume of SSBs were 72·3 (93·0) L and 33 %, respectively. Corresponding values for AFSBs were 32·5 (79·3) L (15 %), and USBs were 112·5 (100·9) L (52 %). Larger households purchased more of all beverage types except AFSBs. Total purchases were similar by income, but households earning < $NZ 30 000 purchased fewer AFSBs and USBs (but not SSBs) than households earning > $NZ 90 000. Total and USB purchases were unchanged over time, but SSBs dropped by 5·9 L (P-trend = 0·04), and AFSBs increased by 5·3 L (P-trend = 0·00).

CONCLUSIONS

USBs contributed the most to household beverage purchases. Total purchases were higher for larger households and similar by income, including for SSBs. The reduction over time was too small for health benefits. Findings support policies and interventions to reduce SSB consumption and highlight the importance of focusing on equitable outcomes.

Maternal determinants of dietary patterns in infancy and early childhood in the Growing up in New Zealand cohort

Given the importance of diet in early life, assessing children's diet is crucial to guide interventions. Using data from a nationally generalizable New Zealand (NZ) birth cohort we examined children's dietary patterns at 9- (n = 6259), 24- (n = 6292), and 54-months (n = 6131), and their association with maternal sociodemographic and health behaviours. At each time-point, children's dietary patterns were identified using principal components analysis. We then used multivariate linear regression to examine associations between each pattern and maternal variables. At 9-, 24- and 54-months, two dietary patterns were identified, explaining 36.4%, 35.3% and 33.6% of children's intake variability, respectively. Refined high in sugar, salt and fat dietary pattern, at all time-points, was characterized by high positive loadings in white/refined breads and cereals, and items with high sugar, sodium, and fat content. At 24-months, Refined high in sugar, salt and fat also included a high positive loading with protein food groups. Fruit and vegetables dietary pattern, at all time-points, had high positive loadings for fruits and vegetables (with type varying across time-points). Fruit and vegetables also included high loading in whole grain options of breads and cereals at 24-months and the protein food group was part of this dietary pattern at 9- and 54-months. Children's scores on the Refined high in sugar, salt and fat pattern had strong associations with maternal smoking habits, education level, ethnicity, and maternal scores in the "Junk" and "Traditional/White bread" dietary patterns (constructed from an antenatal interview). Children's scores on the Fruit and vegetables pattern had strong associations with the maternal scores in the dietary pattern "Health Conscious". Interventions to improve diet in early life in NZ need to be responsive to ethnicity and suitable for people of all education levels. Interventions that improve maternal health behaviours may also improve children's diet.

Child feeding indexes measuring adherence to New Zealand nutrition guidelines: Development and assessment

New Zealand (NZ) lacks nationally representative or generalisable information on the dietary intakes of pre‐schoolers. We used Growing Up in New Zealand cohort data to i) develop child feeding indexes (CFIs) based on National Food and Nutrition Guidelines for 2‐ and 4.5‐year‐olds; ii) describe the cohort adherence to the guidelines at 2 (n = 6046) and 4.5 years (n = 5889) and; iii) assess the CFIs’ convergent construct validity, by exploring associations with maternal sociodemographic and health behaviours and with child body mass index for age (BMI/age) and the waist‐to‐height ratio at 4.5 years. The CFIs scores ranged from 0 to 11, with 11 representing full adherence to the guidelines. Associations were tested using multiple linear regressions and Poisson regressions with robust variance (risk ratios [RR], 95% confidence intervals, 95% CI). The CFIs mean scores (SD) at 2 and 4.5 years were, respectively, 6.13 (1.21) and 6.22 (1.26) points. Maternal characteristics explained, respectively, 27.2% and 31.9% of the variation in the CFIs scores at 2 and 4.5 years. In the adjusted model at the 4.5‐year interview, in relation to girls ranked in the 5th quintile, those in the 2nd (RR, 95% CI: 1.48; 1.03; 1.24) and 4th (1.53; 1.05; 2.23) quintiles of the CFI were more likely to have BMI/age > +2z (World Health Organization growth standards) at 4.5 years. At 2 and 4.5 years, most children fell short of meeting national guidelines. The associations between the CFIs scores at both time points with maternal characteristics and with children's body size at 4.5 years were in the expected directions, confirming the CFIs’ convergent construct validity among NZ pre‐schoolers.

Data from a nationally generalisable New Zealand birth cohort was used to i) develop child feeding indexes (CFIs) for 2 and 4.5‐year‐olds based on National Food and Nutrition Guidelines (NFNG); ii) describe the cohort's adherence to the NFNG; and iii) assess the CFIs' construct validity.

There was low adherence to the overall NFNG at 2 and 4.5 years and adherence was predicted by inequalities in maternal sociodemographics and health behaviours.

In unadjusted regressions, children ranked in the 2nd–4th quintiles of the CFIs, in relation to those ranked in the highest quintiles (5th), were more likely to have higher body size and adiposity at 4.5 years. In adjusted model, girls with lower adherence to the NFNG at 4.5 years were more likely to have BMI/age > +2z at 4.5 years.

Associations between CFIs scores with maternal characteristics and child adiposity were in the expected directions, confirming the indexes' construct validity.

Associations between antenatal maternal diet and other health aspects with infant temperament in a large multiethnic cohort study: a path analysis approach

OBJECTIVES

The aim of this study was to assess the association of antenatal maternal dietary patterns (DPs) and other health aspects with infant temperament in a large multiethnic cohort, taking maternal personality and prenatal stress into account.

DESIGN AND METHODS

Using data from 3968 children born in 2009/2010 and their mothers from the Growing Up in New Zealand cohort, infant temperament was assessed at 9 months using the Infant Behavior Questionnaire-Revised Very Short Form. Maternal antenatal diet and other health aspects were assessed antenatally. Maternal DPs (n=4) were derived using principal components analysis based on food intake reported on a 44-item food frequency questionnaire. Path analyses investigated factors associated with infant temperament, namely maternal personality, prenatal maternal stress, DPs and other health aspects, including potential inter-relations and mediating effects.

RESULTS

Women who scored higher in the fusion DP (standardised beta (β)=0.05; 95% CI 0.02 to 0.09) and healthy DP (β=0.05; 95% CI 0.02 to 0.09), who exercised more (β=0.04; 95% CI 0.01 to 0.07), and who drank less alcohol (β=-0.05; 95% CI -0.08 to -0.02) were more likely to have infants with an overall less difficult temperament. Sex-specific differences were found in the associations between maternal DP and infant temperament. Maternal personality and prenatal stress were significantly associated with all dimensions of infant temperament. The strongest predictors for a more difficult temperament were prenatal stress (β=0.12; 95% CI 0.08 to 0.15) and the personality dimensions neuroticism (β=0.10; 95% CI 0.07 to 0.14) and extraversion (β=-0.09; 95% CI -0.12 to -0.06).

CONCLUSIONS

Associations of antenatal maternal diet and health aspects with infant temperament were statistically significant but small. While they should not be overinterpreted as being deterministic, the findings of this study support the link between maternal modifiable health-related behaviours and infant temperament outcomes.

Who We Seek and What We Eat? Sources of Food Choice Inspirations and Their Associations with Adult Dietary Patterns before and during the COVID-19 Lockdown in New Zealand

Research shows the shaping of food choices often occurs at home, with the family widely recognised as significant in food decisions. However, in this digital age, our eating habits and decision-making processes are also determined by smartphone apps, celebrity chefs, and social media. The ‘COVID Kai Survey’ online questionnaire assessed cooking and shopping behaviours among New Zealanders during the 2020 COVID-19 ‘lockdown’ using a cross-sectional study design. This paper examines how sources of food choice inspirations (cooking-related advice and the reasons for recipe selection) are related to dietary patterns before and during the lockdown. Of the 2977 participants, those influenced by nutrition and health experts (50.9% before; 53.9% during the lockdown) scored higher for the healthy dietary pattern. Participants influenced by family and friends (35% before; 29% during the lockdown) had significantly higher scores for the healthy and the meat dietary patterns, whereas participants influenced by celebrity cooks (3.8% before; 5.2% during the lockdown) had significantly higher scores in the meat dietary pattern. There was no evidence that associations differed before and during the lockdown. The lockdown was related to modified food choice inspiration sources, notably an increase in ‘comforting’ recipes as a reason for recipe selection (75.8%), associated with higher scoring in the unhealthy dietary pattern during the lockdown. The lockdown in New Zealand saw an average decrease in nutritional quality of diets in the ‘COVID Kai Survey’, which could be partly explained by changes in food choice inspiration sources.

Which companies dominate the packaged food supply of New Zealand and how healthy are their products?

Improvement of national food supplies are an opportunity to improve a country's health. Our aim was to identify the major food companies manufacturing packaged foods and non-alcoholic beverages available in New Zealand supermarkets in 2018; to assess the healthiness of products using (1) the Health Star Rating (HSR) system, (2) Australian Dietary Guidelines classification (core/discretionary), and (3) by level of processing; to compare the healthiness of products displaying and not displaying the HSR and; to assess potential for food reformulation within selected food sub-categories. Information on packaged foods was obtained from the Nutritrack supermarket database. Companies that manufactured each food and brand were identified using company websites and the New Zealand companies register. In total, 13,506 packaged products were mapped to 1,767 brands and 1,214 companies. Based on market share of products available for sale (Euromonitor data), there were 22 dominating companies producing 31% of products and 17% of brands. Fifty-nine percent of products were classified as unhealthy (HSR <3.5/5 stars), 53% as discretionary, and 69% as ultra-processed. Products displaying the HSR on the package had a higher mean HSR ±SD than if the HSR was not displayed (3.2±1.3 versus 2.5±1.4, p = 0.000). Efforts to improve the healthiness of products should be directed to the 22 food companies dominating this market share, particularly in the core foods groups which are currently less likely to meet Heart Foundation reformulation targets (bread, breakfast cereals, cheese, canned baked beans, yoghurt). The New Zealand supermarket packaged food supply included in the Nutritrack database is dominated by a small number of companies and is mostly unhealthy. Government leadership is required to improve the healthiness of the packaged food supply and provide adequate information to consumers. This includes interventions setting reformulation targets for core food groups, setting population nutrient intake targets and mandating that the HSR is displayed on all products.

[Estimated prevalence of hypertension and associated factors in Krenak indigenous adults in the state of Minas Gerais, Brazil]

This cross-sectional study in 2016 aimed to describe the estimated prevalence of systemic arterial hypertension and associated factors in Krenak adults and elderly in an indigenous community located along the Rio Doce in eastern Minas Gerais state, Brazil. We measured weight, height, waist circumference, systolic blood pressure, diastolic blood pressure, and capillary blood glucose. Sociodemographic and lifestyle information was obtained from a face-to-face questionnaire. Poisson regression models were constructed to estimate independent associations between the target variables and hypertension. Prevalence of hypertension was 31.2% (95%CI: 24.4-37.9) in Krenak indigenous. The final model showed an independent association with increasing age, abdominal obesity, and hyperglycemia. The results highlight the need for effective measures in prevention, diagnosis, and follow-up of modifiable risk factors for hypertension, since high prevalence of this condition was observed in the Krenak indigenous community.

[Nutritional status and environmental and health conditions of Pataxó indigenous children, Minas Gerais State, Brazil]

To describe the nutritional status and the environmental and health conditions of the Pataxó children from five villages of Minas Gerais State, Brazil. Among the under 10 years old, weight and height/length were classified according to the growth references of World Health Organization. Questionnaires evaluating environmental conditions of the households and health conditions of under 5 years old were based in the First National Survey of Indigenous People's Health and Nutrition. Among the 70 children evaluated (93.3%), 34 were under 5 years old. Nutritional deficits were not observed and overweight was registered for 11.4% of the children. Most of the children (74.3%) lived in households with electric energy, 95% in households with toilets and 52.9% in households that threw waste in septic tanks. Six or more antenatal appointments were reported by 82.4% of the mothers of the under five years old and 91.2% started the antenatal appointments within the first trimester of pregnancy. Among the causes of hospitalizations in the previous 12 months (23.5%), only one was due to diarrhea and none to respiratory infection. Universal coverage was observed for the majority of the vaccines. The absence of nutritional deficits among the Pataxó children may be associated to better housing and sanitation conditions and coverage of basic childhood health actions when compared to the conditions reported by the First National Survey of Indigenous People's Health and Nutrition and related studies with other specific indigenous peoples. The current study aims to back discussions and measures to improve the nutritional status of indigenous children in Brazil.

[Management, operations, and menus in Kaingáng indigenous schools participating in the National School Nutrition Program in Rio Grande do Sul State, Brazil.]

Few studies have focused on the National School Nutrition Program (PNAE) in indigenous schools in Brazil. The current study describes the program's operations, management, and menus in 35 Kaingáng indigenous schools in Rio Grande do Sul State, Brazil. A cross-sectional study design was used to obtain information on the program through questionnaires submitted to the Regional Educational Offices (CRE) and to the schools. The menus suggested to the schools by the regional offices were obtained. There were no Centers for Indigenous Education in the regional offices. All the assistant principals were indigenous, 26 schools (74.6%) practiced local management of the meal program, and 34 (97.1%) reported purchasing food from local markets. Most cooks (63.9%) had temporary work contracts with the schools and 65.7% were indigenous. Low offerings of veges, milk and dairy products were observed in around 60% of the menus, and legumes and fruits low in around 80%. It points out the need for more studies about the indigenous PNAE and intends to support public policies in health, food and nutrition for the national indigenous school .

Waist circumference and waist circumference to height ratios of Kaingáng indigenous adolescents from the State of Rio Grande do Sul, Brazil

The aim of this study was to describe the distribution of waist circumference (WC) and WC to height (WCTH) values among Kaingáng indigenous adolescents in order to estimate the prevalence of high WCTH values and evaluate the correlation between WC and WCTH and body mass index (BMI)-for-age. A total of 1,803 indigenous adolescents were evaluated using a school-based cross-sectional study. WCTH values > 0.5 were considered high. Higher mean WC and WCTH values were observed for girls in all age categories. WCTH values > 0.5 were observed in 25.68% of the overall sample of adolescents. Mean WC and WCTH values were significantly higher for adolescents with BMI/age z-scores > 2 than for those with normal z-scores. The correlation coefficients of WC and WCTH for BMI/age were r = 0.68 and 0.76, respectively, for boys, and r = 0.79 and 0.80, respectively, for girls. This study highlights elevated mean WC and WCTH values and high prevalence of abdominal obesity among Kaingáng indigenous adolescents.

Desnutrição em crianças menores de 60 meses em dois municípios no Estado do Acre: prevalência e fatores associados

OBJETIVO: Investigar a prevalência da desnutrição e fatores associados em crianças menores de 60 meses em dois municípios do Estado do Acre. MÉTODOS: Estudo transversal de base populacional realizado com 667 crianças da área urbana dos municípios de Acrelândia e Assis Brasil. A prevalência da desnutrição foi calculada pelo padrão de crescimento da Organização Mundial da Saúde de 2006, com o ponto de corte -2 escores Z. Informações sobre condições socioeconômicas, acesso aos serviços e cuidado da criança, peso ao nascer e morbidade foram obtidas por questionário estruturado. A regressão de Poisson foi utilizada para identificar os fatores associados à desnutrição de crianças. RESULTADOS: A prevalência do déficit estatura para idade e déficit peso para estatura foi de 9,9% e 4,1%, respectivamente. Os fatores associados ao déficit estatura para idade foram o baixo índice de riqueza (razão de prevalência [RP]: 1,74; intervalo de confiança em 95% [IC95%]: 0,95 - 3,18), analfabetismo do pai ou padrasto (RP: 1,82; IC95%: 1,01 - 3,27), ter 2 ou mais irmãos menores (RP: 2,88; IC95%: 1,45 - 5,72), ausência da mãe biológica no domicílio (RP: 2,63; IC95%: 1,32 - 5,24) e exposição ao esgoto a céu aberto no âmbito domiciliar (RP: 2,46; IC95%: 1,51 - 4,00). Somente o baixo peso ao nascer mostrou-se como fator associado ao déficit peso para estatura (RP: 2,91; IC95%: 1,16 - 7,24). CONCLUSÕES: Nos municípios estudados, a desnutrição em crianças menores de 60 meses apresenta-se como um importante problema de saúde pública, associado aos indicadores de iniquidades sociais, acesso aos serviços de saúde e ausência da mãe no domicílio.

Prevalência e distribuição dos fatores de risco para doenças crônicas não transmissíveis entre adultos da cidade de Lages (SC), sul do Brasil, 2007

OBJETIVO: Descrever as prevalências e distribuições dos fatores de risco para doenças crônicas não-transmissíveis (DCNT) entre adultos da cidade de Lages, Santa Catarina, Brasil. MÉTODOS: Entrevistou-se amostra probabilística (n= 2022) da população adulta na faixa etária de 20 a 59 anos de idade, de ambos os sexos e residentes na zona urbana do município. O processo de amostragem foi por meio de conglomerados. O projeto aplicou questionário estruturado com questões relativas a variáveis demográficas, socioeconômicas, comportamentais e doenças autorreferidas. Para este estudo foram utilizadas as informações sobre os fatores de risco/proteção para DCNT: sexo, idade, escolaridade, índice de massa corporal, circunferência da cintura, tabagismo, atividade física, níveis pressóricos, diabetes mellitus autorreferida e características da alimentação. Foram calculadas as prevalências para os fatores de risco/proteção para DCNT na população total, de acordo com sexo e escolaridade. RESULTADOS: A população estudada é uma população eminente para DCNT, apresentando proporções expressivas de hipertensos (33,78%) e indivíduos com excesso de peso (33,46%), obesidade (23,46%) e obesidade abdominal (43,81%). Com relação às características da alimentação, as mulheres apresentaram maiores prevalências de comportamentos considerados fatores de proteção, em relação aos homens. Foram encontrados menos de 30,0% de indivíduos fisicamente inativos e 45,9% de fumantes ou ex-fumantes. CONCLUSÕES: Estudos descritivos como o presente poderão servir de base para o desenvolvimento de políticas públicas específicas para a população adulta de Lages, de forma a orientar a organização, planejamento e melhoria da qualidade dos serviços de assistência à saúde, buscando a redução na incidência e no impacto das DCNT.

Prevalence and distribution of risk factors for non-communicable chronic diseases among adults from Lages city, south of Brazil, 2007

OBJECTIVE

To describe prevalence and the distribution of risk factors to non-communicable chronic diseases among adults from Lages, Santa Catarina, Brazil.

METHODS

Probabilistic sample of adult urban population, of both genders and aged from 20 to 59 years old was interviewed (n=2022). The sample process was made through conglomerates. It was applied a structured questionnaire with questions related to demographical, socio-economical, and behavior and self-referred diseases. In this study the following informations, related to the risk/protection factors for non-communicable chronic diseases, were used: gender, age, school background, body mass index, waist circumference, smoking, physical activity, pressure levels, self-referred mellitus diabetes and feeding characteristics. Prevalence for risk/protection factors for non-communicable chronic diseases, in the total population and according to gender and school background, was calculated.

RESULTS

The studied population is prone to non-communicable chronic diseases, presenting substantial proportions of hypertension (33.78%), overweight individuals (33.46%), obesity (23.46%) and abdominal obesity (43.81%). In relation to feeding characteristics, women presented higher prevalence of behaviors considered as protection factors, relative to men. It was found less than 30.0% of physically inactive individuals and 45.9% of smokers or ex-smokers.

CONCLUSION

Descriptive studies such as this could be the basis for the development of public policies specific to the adult population of Lages, in order to guide the organization, planning and quality improvement of health assistance services, aiming the reduction in the occurrence and in the impact of non-communicable chronic diseases.

[Food and Nutritional Surveillance System (SISVAN) in children from Rio Grande do Sul State, Brazil: coverage, nutritional status, and data reliability]

This study aimed to evaluate: the coverage of the Food and Nutritional Surveillance System (SISVAN) in the State of Rio Grande do Sul, Brazil, and it Regional Health Offices in 2006; the nutritional status of children 0-10 years of age; and the reliability of data on nutritional status recorded in the system. A cross-sectional descriptive study was conducted with secondary data on 63,320 children. Coverage was defined as the proportion of children younger than 10 years covered by the Family Health Strategy in the State's various municipalities (counties). Height-for-age (H/A) and body mass index for age (BMI/A) were classified according to World Health Organization (WHO) criteria. Agreement between the nutritional classifications recorded in the system and those calculated in this study was evaluated with the weighted kappa coefficient (at 5%). The system's coverage in the State of Rio Grande do Sul was 10.5%. Low height-for-age was found in 7.1% of children and overweight in 8.4%. Agreement between the classifications showed a kappa coefficient of 0.43. The system's coverage and agreement between classifications were both low, and the study showed the coexistence of high overweight and stunting rates in this age group.

Bioelectrical impedance values among indigenous children and adolescents in Rio Grande do Sul, Brazil

OBJECTIVE

To describe the nutritional status of indigenous children and adolescents in Rio Grande do Sul, Brazil, through bioelectrical values, and to compare the nutritional classifications of the anthropometric method to those of the body composition method.

METHODS

A cross-sectional survey was conducted of 3 204 subjects at 35 schools in the 12 Kaingang indigenous lands of Rio Grande do Sul, Brazil. Following World Health Organization recommendations, the weight and height (H) of each subject was measured twice and the body mass index/age (BMI/A) was classified. Body composition was assessed by Bioelectrical Impedance Vector Analysis (BIVA). Resistance (R) and reactance (Xc) were estimated using a bioelectrical impedance analyzer. Divergences between these two methods were performed on RXc graph.

RESULTS

Of the sample, 56.8% were adolescents and 50.6% were males. The mean values of phase angle were higher in adolescents, in males, and in individuals overweight by BMI/A. Mean values of R, Xc, R/H, and Xc/H were higher among children and among those with BMI/A < +2 z scores. Divergences in overweight classification were: male children, 94.6%; male adolescents, 77.1%; female children, 85.4%; and female adolescents, 94.8%.

CONCLUSIONS

The mean values of bioelectrical measures observed among the Kaingang children and adolescent were similar to those found for different populations in other studies. For both gender and age groups, differences were observed between nutritional classifications by BMI/age and by BIVA. These results reinforce the importance of employing multiple techniques, such as anthropometry and BIVA, when conducting nutritional assessments of a population.

Anemia e deficiência de ferro em pré-escolares da Amazônia Ocidental brasileira: prevalência e fatores associados

Estudo transversal de base populacional que investigou prevalênciasde anemia e fatores associados à anemia, anemia ferropriva e deficiência de ferro entre crianças de 6 a 60 meses da área urbana de dois municípios do Acre, Brasil (N = 624). Dosagens de hemoglobina sanguínea, ferritina e receptor solúvel de transferrina plasmáticas foram realizadas mediante sangue venoso. Condições sócio-econômicas, demográficas e de morbidade foram obtidas por questionário. Razões de prevalências foram calculadas por regressão de Poisson em modelo hierárquico. As prevalências de anemia, anemia ferropriva e deficiência de ferro foram de 30,6%, 20,9% e 43,5%, respectivamente. Menores de 24 meses apresentaram maior risco para anemia, anemia ferropriva e deficiência de ferro. Pertencer ao maior tercil do índice de riqueza conferiu proteção contra anemia ferropriva (RP = 0,62; IC95%: 0,40-0,98). Pertencer ao maior quartil do índice estatura/idade foi protetor contra anemia (0,62; 0,44-0,86) e anemia ferropriva (0,51; 0,33-0,79), e ocorrência recente de diarréia representou risco (anemia: 1,47; 1,12-1,92 e anemia ferropriva: 1,44; 1,03-2,01). A infestação por geohelmintos conferiu risco para anemia, anemia ferropriva e deficiência de ferro.

Estado nutricional dos indígenas Kaingáng matriculados em escolas indígenas do Estado do Rio Grande do Sul, Brasil

Caracterizar o estado nutricional de 3.254 Kaingáng de escolas indígenas de 12 terras indígenas do Rio Grande do Sul, Brasil. Transversal de base escolar. Obtidas medidas de peso (P), estatura (E) e circunferência da cintura (CC) conforme Organização Mundial da Saúde - OMS (1995). Classificação do estado nutricional: crianças: índices E/I, P/I e P/E, de acordo com o National Center for Health Statistics (WHO, 1995) e E/I, P/I e índice de massa corporal/idade (IMC/I) de acordo com OMS (2006); adolescentes: IMC/I (OMS, 1995 e 2006) e E/I (OMS, 2006); adultos: IMC (OMS, 1995) e CC (OMS, 2003). Adolescentes representaram 56% dos avaliados, crianças 42,5%, adultos 1,4% e idosos 0,1%. Deficit estatural de 15,1% (OMS, 1995) e 15,5% (OMS, 2006) entre as crianças e de 19,9% entre adolescentes. Freqüências de excesso de peso foram: crianças: 11% (OMS, 1995) e 5,7% (OMS, 2006); adolescentes: 6,7%; adultos: 79,2%. Entre adultos, 45,3% estavam em risco aumentado para doenças metabólicas. Observada a transição nutricional no segmento, caracterizada por prevalências importantes de baixa estatura na infância e adolescência e sobrepeso proeminente em todas as faixas etárias.

Child health and nutrition in the Western Brazilian Amazon: population-based surveys in two counties in Acre State

The article presents prevalence rates for malnutrition, intestinal parasitic infections, anemia, and iron deficiency in under-five children in a population-based cross-sectional survey performed in the urban area of two counties in the Western Brazilian Amazon, Assis Brasil (n = 200) and Acrelandia (n = 477). Available data included: (a) weight and height measurements, standardized as z-scores using the 1977 NCHS reference population, (b) diagnosis of current intestinal parasitic infection, (c) blood hemoglobin levels, and (d) plasma ferritin and soluble transferrin receptor levels. Overall prevalence rates of low weight-for-height, low weight-for-age, and low height-for-age were 3.7%, 8.7%, and 7.5%, respectively, with similar figures in the two towns. Intestinal parasites were detected in 32.5% children; helminths were uncommon. Anemia and iron deficiency were diagnosed in 30.6% and 43.5% of the children, respectively. Evidence of anemia was found in only 47.6% of the children with depleted iron reserves, indicating that hemoglobin measurement alone would severely underestimate the magnitude of iron deficiency in this population. In both towns, anemia and malnutrition were significantly more prevalent among children in the lowest socioeconomic stratum.

Bottle feeding and exposure to Toxocara as risk factors for wheezing illness among under-five Amazonian children: a population-based cross-sectional study

We investigated the prevalence and risk factors for wheezing and asthma in young Amazonian children. A population-based cross-sectional survey of 606 children aged 6-59 months was performed in two small towns in Acre State, Northwestern Brazil. Information on outcome variables (recent wheezing and medical diagnosis of asthma) and demographic, socioeconomic, environmental, maternal and nutritional variables was obtained by interviewing children's mothers or guardians. Infections with intestinal parasites and antibodies to the zoonotic nematode Toxocara were diagnosed using standard laboratory techniques. Multiple unconditional logistic regression models were used to describe associations between independent variables and outcomes. The prevalence of recent wheezing (one or more reported episodes in the past 12 months) was 42.6%, but only 19.8% of wheezing children were also reported to have a medical diagnosis of asthma (prevalence, 8.5%); 21.5% of the children examined had antibodies to Toxocara. Increased risk of asthma was independently associated with early introduction of bottle feeding, defined as <4 months of exclusive breastfeeding [adjusted odds ratio (aOR) = 2.21, 95% confidence interval (95% CI), 1.07-4.59, P = 0.033], and seropositivity to Toxocara (aOR = 2.37, 95% CI 1.17-4.77, P = 0.016), suggesting two potential targets for public health interventions.

[Changes in dietary intake among Japanese-Brazilians in Bauru, São Paulo, Brazil, 1993-2000]

Cross-sectional surveys were performed in 1993 and 2000 on Japanese-Brazilians (n = 328) of both sexes, aged 40 to 79 years in 1993, living in Bauru, São Paulo State. Both surveys examined food intake using food frequency questionnaires. Dietary intake in both surveys was compared to Wilcoxon tests according to gender (p < 0.05). Calories from dietary fat increased by 16% in both genders (mean values in 2000: 31.5% for women and 30.8% for men). When the surveys were compared, the main dietary changes were: (a) a 40% increase in oleic and linoleic acids and calories from fat and (b) a 20% reduction in dietary cholesterol in both sexes. Among women, an increase in total calorie intake with reduced consumption of vegetables and calories from sweets were observed. Despite increased intake of total dietary fat, there was a decrease in cholesterol intake and an increase in oleic and linoleic acids, fruit, and calcium. However, calcium and vegetable consumption is still short of international recommendations.

Association of Dietary Fiber with Temporal Changes in Serum Cholesterol in Japanese-Brazilians

To examine dietary intakes in relation to long-term serum lipoprotein changes in a prospective cohort study with 7 y of follow-up, serum lipids were analyzed by enzymatic methods, while food intake was calculated from validated food frequency questionnaires. First- and second-generation Japanese-Brazilians (n = 316) living in Bauru, São Paulo/Brazil, of both genders, aged 40 to 79 y were assessed at baseline in 1993. Multiple linear regression models were used with changes in serum lipoproteins as the dependent variable and changes in dietary intakes as the independent variables, adjusted for confounding factors. In energy-adjusted analyses, changes in serum total cholesterol were inversely associated with changes in total dietary fiber, fruits/fruit juices and vegetables after adjustment for age and gender. Each increase of 10 g in the consumption of total dietary fiber was associated with a reduction of 12.5 mg/dL in the serum total cholesterol (p<0.05). Our results highlight the importance of increased intakes of total fiber, fruits and vegetables to prevent and control dyslipidemia in Japanese migrants.

Educação para promoção da saúde infantil: relato de experiência em um assentamento de reforma agrária, Vale do Rio Doce (MG)

O trabalho relata uma experiência pedagógica de intervenção para promoção da saúde infantil em um assentamento de reforma agrária no Vale do Rio Doce (MG). No processo, procedimentos pedagógicos grupais e individualizados foram combinados, criando espaços dialógicos de problematização da saúde e nutrição infantil. Foi proposto e planejado um levantamento diagnóstico das condições de saúde das crianças menores de 5 anos; a devolução e a discussão dos dados com a população se deram por meio de reunião coletiva. Foi efetuado atendimento nutricional individualizado às mães das crianças; tratado com as gestantes e nutrizes o tema do aleitamento materno e ministrado um curso de Vigilantes da Saúde das Crianças, com vistas ao monitoramento da saúde infantil no local. Houve grande participação dos assentados nas intervenções, desde o planejamento até a execução das atividades. A estratégia adotada permitiu detectar as intervenções aceitas, as mais efetivas e as que deverão ser reformuladas com a comunidade. Do ponto de vista teórico e metodológico, a experiência permitiu observar os limites e potencialidades de ações que aproximam áreas de saber como sociologia e nutrição em atividades transdisciplinares.

Caracterização do consumo alimentar, ambiente socioeconômico e estado nutricional de pré-escolares de creches municipais

OBJETIVO: Analisar o consumo alimentar, o ambiente socioeconômico, a freqüência de anemia ferropriva e o estado nutricional de pré-escolares. MÉTODOS: A população estudada constituiu-se de 89 crianças de 24 a 72 meses de idade, assistidas em creches municipais de Viçosa, MG. Foram avaliados: nível de hemoglobina, peso, estatura, presença de parasitose, consumo alimentar dos pré-escolares e o perfil biossocioeconômico de suas famílias. RESULTADOS: O estado nutricional do grupo foi considerado satisfatório, e a prevalência de anemia relativamente baixa (11,2%). Condições adequadas de saneamento, nível razoável de escolaridade dos pais, baixo número de filhos e ausência de parasitas envolvidos com a gênese da anemia podem justificar o perfil observado. Não foi observada associação da anemia ferropriva nem com desnutrição nem com parasitose. CONCLUSÃO: Apesar de alguns fatores biossocioeconômicos apresentarem-se favoráveis ao estado nutricional e à baixa prevalência de anemia, observa-se, entretanto, que a insuficiente renda per capita e a dieta deficiente poderão levar esse grupo de pré-escolares, no futuro, a um pior estado de saúde.

Saúde e nutrição de crianças de 0 a 60 meses de um assentamento de reforma agrária, Vale do Rio Doce, MG, Brasil

OBJETIVO: Este estudo avaliou as condições gerais de saúde das crianças de um assentamento rural, localizado no Município de Tumiritinga, Vale do Rio Doce, MG, Brasil. MÉTODOS: Foram obtidos dados de 69 crianças de zero a 60 meses de idade, com relação ao estado nutricional (antropometria e nível de hemoglobina), parasitose intestinal, tempo de aleitamento materno, práticas alimentares e calendário de vacinação. RESULTADOS: Verificou-se que 7,6% das crianças apresentavam déficits nos índices peso/idade e estatura/idade e 47,5%, baixa concentração de hemoglobina. A infestação parasitária foi detectada em 96,1% das 51 crianças que fizeram o exame e 34,0% estavam com a vacinação atrasada. A mediana de tempo de aleitamento materno exclusivo foi de 30 dias e observou-se inadequada freqüência de consumo de alimentos-fontes de ferro. CONCLUSÃO: Dado o aumento dos assentamentos rurais no Brasil e as precárias condições de saúde e nutrição infantil encontradas neste estudo, tornam-se necessárias medidas urgentes e efetivas de intervenção preventiva, voltadas à promoção da saúde dessa população.
