The purpose of this study was to evaluate the anthropometric nutritional status of the adolescent population of Niterói, Rio de Janeiro State, Brazil, and the influence of changes in the adopted body mass index (BMI) cut-offs in the nutritional status assessment of the adolescent population. A population-based survey conducted in 2003 obtained data from a probabilistic sample of 1,734 households and 523 adolescents. The multiple proportions test and prevalence ratios were used to analyze differences between estimates obtained from different BMI cut-offs. Changes in cut-off values from the old to the new recommendation of the World Health Organization (WHO) resulted in a significant increase in overweight prevalence among total, male and female adolescent population (25%, 27% and 23%, respectively) (p < 0.05). There were significant increases in the prevalence of low-BMI-for-age among the total (29% increase) and male (39%) adolescent populations when the proposal of the International Obesity Task Force was compared to current WHO BMI-for-age cut-offs (p < 0.05). It is shown that a simple change in cut-off values used to define the anthropometric nutritional status can significantly modify the nutritional profile of an adolescent population.

Objective: To investigate the agreement between two international criteria for classification of children and adolescents nutritional status. Methods: The study included 778 girls and 863 boys aged from six to 13 years old. Body mass and height were measured and used to calculate the body mass index. Nutritional status was classified according to the cut-off points defined by the World Health Organization and the International Obesity Task Force. The agreement was evaluated using Kappa statistic and weighted Kappa. Results: In order to classify the nutritional status, the agreement between the criteria was higher for the boys (Kappa 0.77) compared to girls (Kappa 0.61). The weighted Kappa was also higher for boys (0.85) in comparison to girls (0.77). Kappa index varied according to age. When the nutritional status was classified in only two categories - appropriate (thinness + accentuated thinness + eutrophy) and overweight (overweight + obesity + severe obesity) -, the Kappa index presented higher values than those related to the classification in six categories. Conclusions : A substantial agreement was observed between the criteria, being higher in males and varying according to the age.

A household survey was conducted to assess the nutritional status of the adult population in Niterói, Rio de Janeiro, Brazil. In the selected households, all adults (³ 20 years) had their body mass and stature measured. Body mass index (BMI) was used to determine the nutritional status according to the World Health Organization classification. The population estimates showed low prevalence of underweight (BMI < 18.5kg/m²), while 45.8% of women and 49.6% of men were overweight/obese (BMI ³ 25kg/m²). Obesity prevalence varied from 5.6% to 19.3% in men and from 9.6% to 21.3% in women, according to age. The prevalence of overweight/obesity was not associated with income (in either men and women) or schooling (in men), but there was an inverse relationship between schooling and overweight/obesity in women. The prevalence of underweight decreased with increasing mean income in the census enumeration area. The authors conclude that overweight/obesity is the most prevalent nutritional disorder in both men and women in Niterói. This pattern resembles recent results for the adult population in Southeast Brazil as a whole, where Niterói is located.

AbstractBackgroundOne of the significant outcomes of health education is health literacy (HL), which should be expanded to improve health promotion.ObjectiveThe aim of this study was to assess HL and its relationship with Body Mass Index (BMI) in female adolescent students.SubjectsThis study was conducted on 235 female students (aged 13–15 years) which were selected with cluster sampling.MethodsFor assessing HL, the Newest Vital Sign (NVS) was used and BMI Z-score was evaluated following the World Health Organization (WHO) guidelines. Data were analyzed using SPSS version 16.ResultsBased on this study’s results, 11.5%, 37% and 51.5% of adolescents had adequate HL, limited HL and inadequate HL, respectively. There was a negative correlation between adolescents HL and BMI, rs= −0.233 (p < 0.001).ConclusionMost of adolescents had limited HL and students with higher BMI had a worse HL score. As a matter of fact, as adequate HL has a significant role for promoting health in the society policy makers must design educational programs for adolescents especially in non-medical settings such as schools where adolescents spend most of their time.

Aim. To investigate physical development of children in Voronezh region in different age groups in 2011-2014 in comparison with the regional studies data in 1997-1999. Methods. The study was performed on 5644 children aged 1-18 years of health groups I and II in comparison with the data of 10 247 children aged 1-14 years examined in 1997-1999. Body height, weight and body mass index Z-scores, calculated using WHO AnthroPlus software, were evaluated. Results. Children’s Z-score values for body height in 2011-2014 were higher than in 1997-1999 in all age groups and at the age of 1-9 years these values exceeded World Health Organization (WHO) standards. Girls’ height approached the standards in 10-14 and 15-18 years, and boys’ height - in 15-18 years. Body weight of children aged 2-8 years was higher than the regional data in 1997-1999 and WHO standards approaching them at the age of 9. Body mass index increase compared to WHO standards was revealed in children aged 1-4 years (p=0.000), and in 2011-2014 the reported differences were less prominent than in 1997-1999. In 2011-2014 among 15-18-years-old girls the shift of body mass index values to the lack of body weight was noted, in 1997-1999 the same changes were found out for 10-14-years-old girls. Conclusion. In 2011-2014 specific attention was required to be paid to physical development of children at the age from 1 to 4 years due to overweight risk of and girls aged 15-18 years due to probable underweight risk.

Abstract Background Triglyceride glucose-body mass index (TyG-BMI) has been recommended as an alternative indicator of insulin resistance. However, the association between TyG-BMI and pre-diabetes remains to be elucidated. Methods More than 100,000 subjects with normal glucose at baseline received follow-up. The main outcome event of concern was pre-diabetes defined according to the diagnostic criteria recommended by the American Diabetes Association (ADA) in 2018 and the World Health Organization (WHO) in 1999. A Cox proportional hazard regression model was used to evaluate the role of TyG-BMI in identifying people at high risk of pre-diabetes. Results At a mean observation period of 3.1 years, the incidence of pre-diabetes in the cohort was 3.70 and 12.31% according to the WHO and ADA diagnostic criteria for pre-diabetes, respectively. The multivariate Cox regression analysis demonstrated that TyG-BMI was independently positively correlated with pre-diabetes, and there was a special population dependence phenomenon. Among them, non-obese people, women and people under 50 years old had a significantly higher risk of TyG-BMI-related pre-diabetes (P-interaction< 0.05). Conclusions These findings suggest that a higher TyG-BMI significantly increases an individual’s risk of pre-diabetes, and this risk is significantly higher in women, non-obese individuals, and individuals younger than 50 years of age.

Currently in the world the main diagnostic parameter for assessing obesity is the magnitude of body mass index. In children, taking into account the growth and body weight indicators that dynamically change as the child grows up, it is common to use not absolute, but relative values of body mass index percentiles or standard deviations. The lecture examined various systems and methods for assessing the physical development of children in the world and in Russia domestic ones, R.N. Dorokhova and I.I. Bakhraha, World Health Organization (WHO), International Group for the Study of Obesity. A comparative analysis of the existing systems and the validity of the currently adopted Federal recommendations on the diagnosis of obesity in children based on the recommendations of WHO has been carried out.

Abstract Background Exposures to human immunodeficiency (HIV) and antiretroviral therapy in utero may have adverse effects on infant growth. Among children born in Denmark and aged 0–5 years, we aimed to compare anthropometric outcomes in HIV-exposed but uninfected (HEU) children with those in children not exposed to HIV. Methods In a nationwide register-based study we included all singleton HEU children born in Denmark in 2000–2016. HEU children were individually matched by child sex, parity, and maternal place of birth to 5 singleton controls born to mothers without HIV. Weight-for-age z (WAZ) scores, length-for-age z (LAZ) scores, and weight-for-length or body mass index–for–age z scores were generated according to the World Health Organization standards and the Fenton growth chart for premature infants. Differences in mean z scores were analyzed using linear mixed models, both univariate and adjusted for social and maternal factors. Results In total, 485 HEU children and 2495 HIV-unexposed controls were included. Compared with controls, HEU children were smaller at birth, with an adjusted difference in mean WAZ and LAZ scores of −0.29 (95% confidence interval [CI], −.46 to −.12) and −0.51 (95% CI, −.71 to −.31), respectively (both P ≤ .001). Over time, there was a trend toward increasing WAZ and LAZ scores in HEU children, and there was no significant difference in adjusted WAZ scores after age 14 days (−0.13 [95% CI, −.27 to .01]; P = .07) and LAZ scores after age 6 months (−0.15 [95% CI, −.32 to .02]; P = .08). Conclusion Compared with a matched control group, HEU children were smaller at birth, but this difference decreased with time and is not considered to have a negative effect on the health and well-being of HEU children during early childhood.

This study analyzed the association between individual and household factors and the incidence of trachoma among a population aged between 1 and 9 years in the state of Pernambuco. This was a population-based household study conducted using a population-based sample of residents from 96 census sectors of the 1778 sectors considered to be at social risk in the state. The estimated odds ratio of the univariate analysis presented a confidence interval of 95%. Weights and clusters were adjusted through the Generalized Linear and Latent Mixed Model (GLLAM) method. Trachoma cases were the dependent variable in the multivariate analysis. The independent variables were selected through the stepwise forward method, with an input criterion of 20% (p < 0.20) and an output criterion of 10% (p < 0.10). The prevalence was 6.65%. Trachoma was associated with a female sex, age of 5–9 years, either the absence of use or infrequent use of soap to wash the hands and face, the presence of nasal secretion, a lack of piped water from a public supply system, a greater number of rooms used for sleeping, a greater number of people living in the same household, and a family income of up to one minimum monthly wage. The prevalence of follicular trachoma in Pernambuco was higher than what is recommended by the World Health Organization (WHO).
