Characteristics associated with dietary patterns in Brazilian children under two years of age

OBJECTIVE

To analyze the dietary patterns of Brazilian children under two years of age and assess their association with sociodemographic characteristics and health service use.

METHODS

This is a cross-sectional study with data from the 2013 National Health Survey (PNS). Patterns were found for two age groups by principal component analysis and their correlation with characteristics of interest was tested by linear regression models.

RESULTS

We found two dietary patterns for our groups. The first consisted of the consumption of fresh or minimally processed foods and the second, of ultra-processed foods. The greater adherence of children between six and 11 months to the first pattern was associated with higher per capita family income and urban residences in the most developed regions of Brazil. At 12 months or more, adherence related to white race/color, higher per capita family incomes, residence in more developed regions, and visits to private childcare. Adherence to the second pattern among children under one year of age was inversely associated with Yellow or Indigenous race/color, residence in the Brazilian Northeast, and childcare in specialized public or private services. At 12 months or more, greater adherence was directly associated with Black or Brown children who resided in more developed regions, and inversely associated with those living in the Brazilian Northeast.

CONCLUSION

We found two opposite dietary patterns in Brazilian children under two years of age and that several social determinants modify their chance of adhering to these patterns.

Temporal trend of simultaneous risk factors for chronic non-communicable diseases: National School Health Survey 2009, 2012, 2015

OBJECTIVE

To analyze the temporal trend of simultaneous occurrence of behavioral risk factors for chronic non-communicable diseases in Brazilian school adolescents.

METHODS

Ecological time-series study that analyzed data from the three editions of the National Survey of School Health with students in the 9th year of public and private schools. Cluster analysis was performed to identify the simultaneity of the following factors: irregular consumption of fresh or minimally processed foods, regular consumption of processed and ultra-processed foods, insufficient level of physical activity during leisure time, consumption of alcoholic beverages, use of cigarettes and illicit drugs. The cluster trend was tested using simple linear regression.

RESULTS

The sample was composed of 173,310 school adolescents. Sixty-four possible combinations were evaluated, resulting in the formation of six clusters. The grouping formed by all factors showed the highest ratios observed/expected prevalence in the last two years of the series. The highest ratios were observed for combinations in which alcohol and cigarettes were present. These substances integrated five of the six clusters. One of the groups (insufficient level of physical activity during leisure time + consumption of alcoholic beverages + use of cigarettes and illicit drugs) had an upward trend throughout the series.

CONCLUSION

The trend analysis showed four out of six clusters remaining stable throughout the series, which shows that the factors are persistently present among school adolescents.

Tendência temporal dos fatores de risco simultâneos para doenças crônicas não transmissíveis: Pesquisa Nacional de Saúde do Escolar 2009, 2012, 2015

RESUMO: Objetivo: Analisar a tendência temporal da ocorrência simultânea de fatores de risco comportamentais para doenças crônicas não transmissíveis em adolescentes escolares brasileiros. Métodos: Estudo ecológico de série temporal, que analisou os dados das três edições da Pesquisa Nacional de Saúde do Escolar dos alunos do 9º ano de escolas públicas e privadas. Realizou-se a análise de cluster para a identificação da simultaneidade dos seguintes fatores: consumo irregular de alimentos in natura ou minimamente processados, consumo regular de alimentos processados e ultraprocessados, nível insuficiente de atividade física no lazer, consumo de bebidas alcoólicas, uso de cigarro e de drogas ilícitas. A tendência dos clusters foi testada utilizando-se regressão linear simples. Resultados: A amostra constituiu-se de 173.310 escolares. Sessenta e quatro possíveis combinações foram avaliadas, havendo a formação de seis clusters. O agrupamento formado por todos os fatores apresentou as maiores razões entre prevalências observadas e esperadas para os dois últimos anos da série. As maiores razões foram verificadas para as combinações em que estavam presentes o álcool e o cigarro. Além disso, essas substâncias integraram cinco dos seis clusters. Um dos agrupamentos (nível insuficiente de atividade física no lazer + consumo de bebidas alcóolicas + uso de cigarro e drogas ilícitas) apresentou tendência crescente durante toda a série. Conclusão: A análise de tendência constatou que quatro de seis clusters mantiveram-se estáveis durante toda a série, demonstrando que os fatores continuam presentes de forma persistente entre os adolescentes escolares.

Sampling plan and methodological aspects: a household healthcare survey in Piauí

OBJECTIVE

To describe the methodological aspects of the Piauí home healthcare survey (ISAD-PI) and assess the relation between sampling plan, precision, and design effects, assuming that population health surveys are relevant instruments for health monitoring.

METHODS

ISAD-PI was a population-based cross-sectional study that analyzed the living conditions and health status of the population residing in urban areas in the municipalities of Teresina and Picos, in Piauí. Sampling was carried out by conglomerates in two stages: Primary Sampling Units and households. To calculate the sample size, we considered the stratification of the population in both cities, according to the age of the individuals. We evaluated the “non-response” rate (NRR) and estimated the proportions according to sex and age, as well as the prevalence of social determinants of health in order to assess the compliance of the sampling plan. Analyses related to the precision according to the coefficient of proportion variation of the standard error (Cv-pˆ) and the design effect (deff). Cv-pˆ less than 20% and deff less than 1.5 were considered adequate. The total NRR of households was 38.2% in Teresina and 38.3% in Picos. We carried out twenty-four proportion estimates in relation to age and sex and 48 prevalence of social and health determinants estimates, totaling 72 estimates. Among them, 71 had Cv-pˆ less than 20% and 61 had deff less than or equal to 1.5.

CONCLUSION

Data generated from the ISAD-PI may contribute to the assessment of health and morbidity conditions in the population. Furthermore, methodological aspects employed in this research may serve as a basis for studies carried out in other cities in Brazil.

An analysis of risk factors for arterial hypertension in adolescent students

The objective of the study was to evaluate some risk factors for increases in systemic arterial blood pressure. This transversal study was carried out with 145 individuals from 12 to 18 years of age at two state schools in the city of Pico in the state of Piauí in Brazil. The majority were female (62.8%). The median age was 14.8 years (±3.19). It was ascertained that 13 of the subjects (9.0%) were overweight [CI% 73.0-86.0]. Elevations in waist circumference were found in 31 (21.4%) and 76 (52.4%) had elevated arterial blood levels. There was no statistically-significant association between the above-cited risk factors and gender (p=0.088; 0.999; 0.204, respectively). However, 44.8% of the adolescents had at least one risk factor associated with arterial hypertension; 15.9% had two, and 2.1% had three. The study confirms the influence of the risk factors on arterial pressure values among adolescents. Being aware of these factors means that nurses can intervene with health education measures.

Identification and analysis of antinutritional factors in possible interactions between medications and food/nutrients in hospitalized patients

ABSTRACT Objective: To identify and analyze the presence of antinutritional factors in possible interactions between medications and foods/ nutrients of the diets prescribed for patients of the Hospital Regional Justino Luz, in the city of Picos (PI) in order to suggest their likely mechanisms. Methods: The sample was made up of 120 medical records of hospitalized patients. The charts were analyzed to verify the presence or absence of interactions between medications and foods/nutrients of the diets prescribed to the patients at the Hospital Regional Justino Luz, emphasizing the action of antinutritional factors in these interactions. Results: Of the 189 medications prescribed, 128 (67.7%) had a possible interaction with food, totaling up 98 possible interactions between nutrients/foods and medications. Therefore, 20 (20.4%), 12 (12.2%) and 11 (11.2%) possible interactions were identified with captopril, acetylsalicylic acid and spironolactone, respectively, representing, in this order, the greatest frequencies of possible interactions among drugs and foods. A total of nine antinutritional factors were found in seven vegetable foods prescribed to inpatients, in which five (55.6%) were capable of interacting with the medications. Phytates and tannins had the largest quantity of possible interactions with drugs, each with 4 (26.7%) in a total of 15 interactions. The medications aluminum hydroxide, digoxin, and paracetamol attained greater probability of interaction with antinutrients, with 5 (33.3%), 3 (20%) and 3 (20%) interactions, respectively. Conclusion: Due to the large quantity of antinutritional factors capable of interacting with drugs prescribed for inpatients, the involvement of a multiprofessional team is indispensable so that these possible interactions between foods, antinutritional factors and drugs might be foreseen, detected, and resolved.

Analysis of possible food/nutrient and drug interactions in hospitalized patients

ABSTRACT Objective: To evaluate the prescription in relation to the possible interactions between drugs and foods/nutrients in the diets of patients in the Hospital Regional Justino Luz in the municipality of Picos, Piauí, Brazil. Methods: The sample consisted of 60 medical records of patients admitted at the hospital. The records were analyzed according to the presence or absence of interactions between drugs and foods/nutrients of the prescribed diets. Results: Of the 82 drugs prescribed in all periods, there were 16 drugs (19.5%) with possible interaction with food, a total of 60 interactions between nutrient/food and medicine. Thus, 18 (30%), 10 (17%) and 8 (13%) possible interactions were identified with captopril (cardiovascular drug) with acetylsalicylic acid (anti-inflammatory) and spironolactone (diuretic), respectively representing the highest numbers of interactions among the classes of investigated drugs. It was also found that the total interactions between food/nutrients and drugs, 32 (53%) accounted for interactions with cardiovascular drugs, 13 (22%) with anti-inflammatory drugs, 11 (18%) with diuretic agents e 4 (7%) with drugs that act on the digestive tract. Conclusion: There was a high number of interactions between food/nutrients and medicines emphasizing the need for prior knowledge of these interactions as a way to avoid impairment in the treatment, longer hospital stays and/or damage to the nutritional status of the patients.
