RESUMEN

OBJECTIVE: To validate an adapted instrument that assesses the nutritional environment of food stores in Brazilian urban areas. METHODS: The instrument measured aspects of food environment such as availability, prices, and quality. The Harvard Healthy Eating Pyramid and the degree of processing were used to define healthy foods. The sample included 44 food stores in 3 census tracts in the city of Santos. Inter-rater reliability and stability coefficient were obtained with measurements performed by different individuals at different times. Internal consistency and construct validity were assessed by Cronbach α and the known-groups comparison method, respectively. RESULTS: Inter-rater reliability was high. The mean intra-class correlation coefficient was 0.98 and the mean kappa was 0.77. Cronbach α values ranged from .68 to .93. CONCLUSIONS AND IMPLICATIONS: The instrument can be useful in the development of interventions to promote healthy eating through actions focused on healthy food availability in Brazilian communities.

RESUMEN

OBJECTIVE: To report a case and to discuss the use of psychodynamic psychotherapy (PD-P) to treat individuals at ultra-high risk (UHR) of psychosis. METHODS: An individual at UHR was followed up for 24 months. The baseline evaluation included a psychiatric interview, the Structured Interview for Prodromal Symptoms (SIPS), the Scale of Prodromal Symptoms (SOPS), and neuropsychological assessment. He underwent weekly sessions of PD-P for 12 months and was followed up for 12 months after the end of PD-P. The evaluations were at baseline, after 6-, 12-, and 24-month follow-up. No medication was prescribed during the 24-month follow-up. RESULTS: The prodromal symptoms remitted. The initial total score on the SIPS/SOPS was 37 points. After the first 12 months of PD-P, there was a reduction to 12 points on the SIPS/SOPS score, which stabilized in the 24-month follow-up. There was also a slight improvement in his performance on the neuropsychological evaluations. CONCLUSION: This case report suggests that PD-P can reduce prodromal symptoms; nevertheless, a better understanding of the specificity and efficacy of PD-P as an option of treatment for UHR individuals is needed.


OBJETIVO: Relatar um caso e discutir o uso da psicoterapia psicodinâmica (PD-P) no tratamento de indivíduos com risco ultra-alto (UHR) para psicose. MÉTODOS: Um indivíduo UHR foi acompanhado por 24 meses. A avaliação inicial incluiu entrevista psiquiátrica, aplicação de instrumentos padronizados, Entrevista Estruturada Para Sintomas Prodrômicos (SIPS), a Escala de Sintomas Prodrômicos (SOPS) e avaliação neuropsicológica. O indivíduo teve sessões semanais de PD-P durante os primeiros 12 meses e continuou acompanhamento durante os 12 meses seguintes após o término da PD-P. Avaliações foram feitas no início do estudo e após 6, 12 e 24 meses de seguimento. Nenhuma medicação foi prescrita durante todo o seguimento. RESULTADOS: Os sintomas prodrômicos remitiram. Apresentou, ainda, discreta melhora no desempenho nas avaliações neuropsicológicas. CONCLUSÃO: Este relato sugere que a PD-P pode reduzir os sintomas prodrômicos, no entanto uma melhor compreensão da especificidade e eficácia da PD-P como uma opção de tratamento para os indivíduos UHR é necessária.

RESUMEN

Undernutrition is one of the most important public health problems, affecting more than 900 million individuals around the World. It is responsible for the highest mortality rate in children and has long-lasting physiologic effects, including an increased susceptibility to fat accumulation mostly in the central region of the body, lower fat oxidation, lower resting and postprandial energy expenditure, insulin resistance in adulthood, hypertension, dyslipidaemia and a reduced capacity for manual work, among other impairments. Marked changes in the function of the autonomic nervous system have been described in undernourished experimental animals. Some of these effects seem to be epigenetic, passing on to the next generation. Undernutrition in children has been linked to poor mental development and school achievement as well as behavioural abnormalities. However, there is still a debate in the literature regarding whether some of these effects are permanent or reversible. Stunted children who had experienced catch-up growth had verbal vocabulary and quantitative test scores that did not differ from children who were not stunted. Children treated before 6 years of age in day-hospitals and who recovered in weight and height have normal body compositions, bone mineral densities and insulin production and sensitivity.

RESUMEN

Protein-energy malnutrition promotes adaptive hormonal changes that result in stunting. A previous study showed that stunted children had increased insulin sensitivity and diminished pancreatic beta-cell function. The objectives of the present study were to analyse the glucose, insulin, homeostasis model assessment of insulin sensitivity (HOMA-S) and homeostasis model assessment of pancreatic beta-cell function (HOMA-B) levels after nutritional recovery. The recovered group (n 62) consisted of malnourished children after treatment at a nutrition rehabilitation centre. At the beginning of treatment their age was 2.41 (sd 1.28) and 2.31 (sd 1.08) years, weight-for-age Z score - 2.09 (sd 0.94) and - 2.05 (sd 0.55) and height-for-age Z score - 1.85 (sd 1.11) and - 1.56 (sd 0.90), for boys and girls respectively. The control group consisted of well-nourished children without treatment (n 26). After treatment, boys of the recovered group gained 1.29 (sd 1.06) Z scores of height-for-age and 1.14 (sd 0.99) Z scores of weight-for-age, and girls, 1.12 (sd 0.91) and 1.21 (sd 0.74) Z scores respectively. No differences were found between control and recovered groups in insulin levels for boys (P = 0.704) and girls (P = 0.408), HOMA-B for boys (P = 0.451) and girls (P = 0.330), and HOMA-S (P = 0.765) for boys and girls (P = 0.456) respectively. The present study shows that the changes observed previously in glucose metabolism and insulin were reverted in children who received adequate treatment at nutritional rehabilitation centres and showed linear catch-up.

RESUMEN

OBJECTIVE: The objective of this study was to determine whether central fat distribution varies between children who were growth retarded as young children and normal-height children from the same impoverished communities of São Paulo, Brazil. METHODS: A prospective study of 50 stunted and normal-height children in São Paulo, Brazil was conducted in which children were measured for changes in fat mass (FM) and fat distribution (using dual-energy X-ray absorptiometry and anthropometry) and Tanner stage over a 4-y period. Statistical analyses included multiple linear regression to control for confounding factors and Student's t test was used to estimate group differences. RESULTS: At follow-up, stunted children were shorter, weighed less, and had less total FM compared with control children. There were no differences between the two groups with respect to percent FM or percent truncal FM (%TrFM). Linear regression analyses were used to determine that stunted children had 1) increased TrFM (independent of FM); 2) increased %TrFM (independent of FM, gender, and Tanner stage), and 3) a borderline significantly greater change in TrFM (independent of FM, gender, and Tanner stage). CONCLUSION: Stunted children are more likely to deposit fat centrally when entering puberty, a significant risk factor for chronic diseases. Our results may explain part of the association between early growth retardation and later risk for metabolic diseases.

RESUMEN

The nutritional programming hypothesis proposes that early life malnutrition is related to an increase in body fat later in life. Brazilian boys and girls (n = 94; 4-14 y old) were studied. Malnourished children treated in a Nutrition Recovery Center, were followed up and divided into 2 groups: the Outpatient group (recovered after outpatient care, n = 28), and the Day-hospital group (recovered after day-hospital care, n = 38). They were compared with a Control group (healthy individuals without intervention, n = 28). Nutritional recovery was confirmed by anthropometry. Body composition was evaluated by dual-energy X-ray absorptiometry. Both recovered groups had a greater increase in height-for-age Z-scores than in weight-for-age Z-scores after treatment (P < 0.03). Body fat mass (kg) and the percentage of body fat were significantly lower in recovered groups of girls and boys compared with controls. Among boys, lean mass/height (kg/cm), fat-free mass (kg) and the fat-free mass index (kg/m(2)) were significantly lower in the Outpatient and Day-hospital groups than in Controls, but girls did not differ. Bone mineral content (BMC)/height (g/cm) did not differ between the recovered girls and the girls in the Control group (P < 0.15) or between the boys in the Day-hospital group and those in the Control group (P = 0.06). The Outpatient boys group had lower BMC/height than boys in the Control group (P = 0.02). This study demonstrates that when malnourished children receive adequate treatment, linear catch-up growth occurs and is followed by appropriate gain in lean body mass and BMC.

RESUMEN

In developing countries nutritional deficit during prenatal and continuing in post-natal life is very common. This condition leads to stunting and important metabolic changes. Over 30% of children in the world are stunted. The metabolic resultants of nutritional deficit during growth are classically known to aim at energy conservation. This review summarizes data from Brazil, a developing country undergoing the double burden of obesity and undernutrition, especially among the poor, and suggests that stunting or chronic undernutrition increases the risk of obesity and hypertension later in life. Around 60 million people are under the poverty line in Brazil. In São Paulo, the richest city of the country, 20% of the population live in slums and in Maceió, the capital of one of the poorest states, this percentage reaches 50%. Undernutrition in this population is around 20% among children, with high frequency of infections, anemia, and parasitic infestations, associated with poor sanitation. Among stunted adolescents, we found a high prevalence of hypertension (21%) that is a considerably higher estimate compared to non-stunted adolescents (less than 10%). The prevalence of hypertension in undernourished pre-school children, or in those who recovered from undernutrition, was higher than that in controls (29%, 20% and 2%, respectively, P < 0.001). Among stunted adults eating no more than 66% of the requirements (adjusted for stature), overweight/obesity was 35% in women and 25% in men. The prevalence of hypertension was 44% among stunted women and 18% among stunted men. Fifty per cent of stunted and obese women had hypertension. These data reinforce the important association between undernutrition and hypertension from childhood through adulthood. Health policies for preventing and combating childhood undernutrition should have an impact on the morbidity and mortality related to hypertension during adulthood.
