“…Following multiple linear regression analysis, it was possible to observe that mothers of short stature were also the oldest, and this suggests a secular tendency of the evolution of stature (29) . Such a finding identifies a limitation of the present study, however, since it was not possible to determine whether the stature of shorter mothers had been influenced by their early nutritional status.…”

The objectives of the study were to investigate whether the health conditions of mothers with short stature differed from those with normal stature, and to establish if these aspects were associated with the health of the offspring. Data relating to health and socio-economic, demographic and anthropometric conditions were collected from a probabilistic sample population consisting of 1180 mothers and 1511 children (, 10 years) living in the semi-arid region of the State of Alagoas, Brazil. Mothers were categorised according to stature, with those in the 1st quartile being defined as of short stature and those in the 4th quartile being defined as of normal stature and serving as a reference for the comparison of variables of interest. Following verification that maternal stature fulfilled parametric assumptions, its associations with the other variables were determined by calculating Pearson correlation coefficients. After excluding strongly self-correlated variables (r $0·70), the remaining variables were analysed by multiple linear regression. The results showed that low maternal stature was independently associated with obesity (percentage body fat $30; P¼ 0·045), abdominal adiposity (waist:hip ratio $0·85; P¼ 0·007) and high systolic blood pressure ($140 mmHg; P¼ 0·006). Short maternal stature was associated with low birth weight (,3000 g; P¼ 0·01) and stunting (height-for-age Z score , 22; P¼ 0·019) in the offspring. Thus, in the semi-arid region of Alagoas, women of short stature presented a higher prevalence of chronic degenerative diseases and produced less healthy children than women of normal stature. Anthropometry: Nutritional status: Stunting: ProgrammingIn line with the majority of developing countries, Brazil is experiencing a process of epidemiological transition characterised by a reduction in the prevalence of infectious-parasitic diseases together with an increase in morbidity and mortality caused by chronic non-transmissible diseases (1) . At the same time, the population is undergoing a nutritional transition in which undernutrition is replaced by obesity, a condition which is rapidly becoming a serious public health problem (2) . National surveys conducted by the Instituto Brasileiro de Geografia e Estatística (Brazilian Institute of Geography and Statistics) (3) have revealed that the prevalence of weight deficit in Brazilian women decreased from 10·2 % in 1974-5 to 5·4 % in 2002-3. In contrast, the frequency of excess body weight increased from 28·6 % to 39·2 %, respectively, over the same time period.One explanation for this phenomenon relates to the modernisation and urbanisation of society, which is associated with alterations in food consumption habits and particularly with a tendency towards high-energy foods (simple carbohydrates and fats) (4) . However, following a study of the dietary profile of a poor population living in a shanty town in Maceió (capital of the State of Alagoas, Brazil), Florêncio et al. (5) discovered that, although the women ingested an average of 7238 kJ (1730 k...

“…An absence of this positive secular variation in stature can be interpreted in one of two ways: 1) As a nutritional deterioration in the socio-economic and cultural conditions of a population group, resulting in environmental conditions that are inadequate for growth; or 2) the population groups is living in ideal conditions and in the past has already fully expressed its genetic growth potential. 21 The first of these two possibilities is more probable in the case of the Terena community being studied, although consideration must also be given to the possibility that the seven-year interval between 1995 and 2002 may not be long enough to detect a secular stature variation. A study of the children of Alto Xingu Indians did not find evidence of increased stature over a twelve-year period from 1980 to 1992.…”

Objective: This study of Terena Indian children less than 10 years old was undertaken in order to compare weight and height in 1995 and 2002 and to evaluate anemia prevalence in 2002.Methods: This was a cross-sectional study of the Limão Verde and Córrego Seco tribes, located in Aquidauana, Mato Gosso do Sul, Brazil. The study enrolled all 253 children who were less than 10 years old in 1995 and 244 who were under 10 in 2002. Their nutritional status was evaluated comparing weight and height with the NCHS (National Center for Health Statistics) reference values (Epi-Info version 6.2). Hemoglobin was assayed using a portable photometer.Results: The percentages of children with weight for age deficit (z score < -2 standard deviations) were 4 and 2.9% in 1995 and 2002 respectively. Percentages of weight for height deficits were 3.6 and 0.8% respectively. Percentages of height for age deficits were 15 and 11.1% respectively. The median z scores for weight, age and weight, and height showed a statistically significant increase during the period between 1995 and 2002 in infants. Between 24 and 60 months, there were increments in median z scores for weight for age and height for age. There was no statistically significant decrease in any of the anthropometric indicators, with reference to z scores. The prevalence rates of anemia were 86.1% for infants 6 to 24 months old (n = 43), 50.8% for those 24 to 60 months (n = 65) and 40.7% for children aged 60 to 120 months (n = 59). Conclusion

“…A investigação da tendência secular do crescimento, principalmente em estatura, é considerada atualmente um importante indicador para o monitoramento de mudanças no padrão econômico, de saúde e nutrição de uma população, quando comparada aos obtidos a partir de dados exclusivamente econômicos (8,9) ; por isso a utilização de dados de crescimento passou a ser uma metodologia que vem sendo proposta para caracterizar as condições de bem estar de populações, bem como a sua evolução ao longo do tempo 10 .…”

INTRODUÇÃO: a análise da distribuição temporal de eventos do processo saúde-doença é uma das estratégias de investigação mais antigas e valiosas para a epidemiologia e para a saúde pública. OBJETIVO: analisar a evolução do perfil antropométrico de pré-escolares, que frequentavam creches municipais da cidade de Taubaté em 1997 e 2007. MÉTODO: foram analisadas variáveis do banco de dados de 2 estudos transversais: um realizado em 1997, com 755 crianças, e outro de 2007, com 1448 crianças. Os dados analisados foram: idade da criança, sexo, peso, estatura e índice de massa corporal (IMC). A transformação dos valores antropométricos em escores Z foi realizada pelo referencial do CDC/NCHS (2000). As comparações entre os dois momentos foram feitas pelo χ-quadrado e pelo teste t-Student, (α = 0,05). RESULTADOS: evidenciou-se tendência de crescimento positiva entre 1997 e 2007 com um aumento significante nos valores médios de escore Z de estatura em ambos os sexos, meninos: 0,04 para 0,39 e meninas: 0,05 para 0,33, e de peso, meninos; -0,03 para 0,26 e meninas: 0,03 para 0,21. As médias de IMC não revelaram diferença significante (meninos de - 0,02 para 0,07 e meninas de 0,09 para 0,12). Observou-se também, entre 1997 e 2007, um aumento na prevalência de crianças emagrecidas, de 9,8 para 12,6% e de crianças com excesso de peso, de 17,0 para 20,9%. CONCLUSÃO: os pré-escolares da cidade de Taubaté tiveram uma tendência secular de crescimento bastante significativa entre 1997 e 2007, mais de estatura do que de peso, que se acompanhou de um aumento na prevalência de crianças emagrecidas e, principalmente, com excesso de peso. Isso indica que, possivelmente, a melhoria das condições de bem estar da população, além de repercutir positivamente no crescimento estatural dos pré-escolares, também pode resultar na instalação de um intenso e precoce processo de transição nutricional, inclusive fora das grandes regiões metropolitanas.
