RESUMO

Background: Given the pervasive issues of obesity and diabetes both in Puerto Rico and the broader United States, there is a compelling need to investigate the intricate interplay among BMI, pregestational, and gestational maternal diabetes, and their potential impact on the occurrence of congenital heart defects (CHD) during neonatal development. Methods: Using the comprehensive System of Vigilance and Surveillance of Congenital Defects in Puerto Rico, we conducted a focused analysis on neonates diagnosed with CHD between 2016 and 2020. Our assessment encompassed a range of variables, including maternal age, gestational age, BMI, pregestational diabetes, gestational diabetes, hypertension, history of abortion, and presence of preeclampsia. Results: A cohort of 673 patients was included in our study. The average maternal age was 26 years, within a range of 22 to 32 years. The mean gestational age measured 39 weeks, with a median span of 38 to 39 weeks. Of the 673 patients, 274 (41%) mothers gave birth to neonates diagnosed with CHD. Within this group, 22 cases were linked to pre-gestational diabetes, while 202 were not; 20 instances were associated with gestational diabetes, compared to 200 without; and 148 cases exhibited an overweight or obese BMI, whereas 126 displayed a normal BMI. Conclusion: We identified a statistically significant correlation between pre-gestational diabetes mellitus and the occurrence of CHD. However, our analysis did not show a statistically significant association between maternal BMI and the likelihood of CHD. These results may aid in developing effective strategies to prevent and manage CHD in neonates.

RESUMO

OBJECTIVES: The objective of this study was to analyse the global burden of disease attributable to undernutrition and high body mass index (BMI) in Brazil and its 27 states, as well as its association with the socio-demographic index (SDI) from 1990 to 2019. STUDY DESIGN: This is an epidemiological time-series study. METHODS: This study analysed the undernutrition and high BMI estimated by the Global Burden of Disease study conducted from 1990 to 2019 for Brazil and its states, using the following metrics: absolute number of deaths, standardised mortality rate, and disability-adjusted life years (DALYs). This study also analysed the correlation between the percentage variation of mortality rates and SDI. RESULTS: A decrease in the number of deaths (-75 %), mortality rate (-75.1 %), and DALYS (-72 %) attributable to undernutrition was found in Brazil and in all regions. As regarding the high BMI, an increase in the number of deaths was found (139.6 %); however, the mortality rate (-9.7) and DALYs (-6.4 %) declined in all regions, except in the North and Northeast regions, which showed an increase. A strong correlation was identified between undernutrition and high BMI with SDI. CONCLUSION: Our study observed a double burden of malnutrition in Brazil, with a reduction in the burden of diseases due to malnutrition in Brazil and variation in the burden due to high BMI according to the socioeconomic status of the region. Public policies are necessary in order to guarantee the human right to a healthy and sustainable diet, together with food and nutrition security and a diminishing of social inequality.

RESUMO

This study investigates the relationship between body image, eating disorders, psychological characteristics, and mood and anxiety symptoms in Chilean youth, with nutritional status, particularly overweight and obesity. With a sample of 1001 participants from five regions of Chile, aged 15 to 23 years. The Eating Disorder Inventory 3 (EDI-3), the Multidimensional Body-Self Relations Questionnaire Appearance Scales (MBSRQ_AS), and the Symptom Inventory Derogatis Revised (SCL90-R) and a sociodemographic questionnaire were used to analyze these variables. A model including nine exogenous (independent) variables and ten endogenous variables, based on a literature review, was evaluated by path analysis. The results show a significant association between factors such as sex, family history of overweight, self-classification by weight, and body dissatisfaction with body mass index (BMI). Eating behaviors such as overeating, and lack of appetite were also found to be influenced by interpersonal sensitivity, overweight preoccupation, and drive for thinness. The study underscores the importance of promoting a positive body image and addressing overweight/obesity from a combined health psychology and public health perspective, highlighting the need for interventions that consider nutritional status, and in particular overweight and obesity, as a phenomenon with multifactorial causes and maintainers.

RESUMO

Objectives: To examine the association of sleep duration and timing with BMI among adults. Also, to identify obesogenic and unhealthy behaviors (e.g.diet/sleep quality, physical activity, screen time, smoking) associated with short sleep duration and late bedtime. Participants: Participants (n=755) were part of exploratory, population-based research, with data collection in a virtual environment. Methods: For purposes of characterizing the population we considered short sleepers<7h/night, and the population bedtime median was used to stratify participants into early and late sleepers (before and after 23:08). Student's t-test and chi-square test were performed to assess differences in characteristics between groups. Linear regression analyses were conducted to determine the association of sleep duration, bedtime, and wake-up time with BMI. Quantile regression was estimated for the 25th, 50th, and 75th quantiles to identify the distributional correlations between BMI and sleep variables. Restricted cubic splines were also used to study the shape of the association between sleep-BMI. Analyses were adjusted for potential confounding variables. Results: BMI decreased by 0.40Kg/m2 for each additional hour of sleep duration [95%CI=-0.68,-0.12,p=0.005] and increased by 0.37 kg/m2 for each additional hour of bedtime [95%CI=0.12,0.61,p=0.003]. The association between bedtime and BMI remained even after adjustment for sleep duration. These effects were higher and stronger with higher BMI values (p75th). Wake-up time did not show statistically significant associations. Conclusions: Because we found that beyond sleep duration, bedtime was significantly associated with BMI, our data reflect the pertinence of assessing sleep timing patterns in disentangling sleep-obesity association. Insights into the characteristics, obesogenic and unhealthy behaviors related to short and late sleep may support specific strategies to prevent and treat excess body adiposity and other negative health outcomes.

RESUMO

Introducción: La literatura sobre el impacto de la educación alimentaria y nutricional de estudiantes universitarios en las prácticas alimentarias es heterogénea. Estudios han informado de que la educación alimentaria y nutricional puede cambiar los hábitos alimentarios y las elecciones alimentarias mientras que otros no encontraron asociación. Objetivo: Determinar la relación entre el conocimiento nutricional, las prácticas alimentarias y la obesidad en estudiantes universitarios nicaragüenses. Métodos: Estudio de corte transversal analítico que utilizó una muestra de 914 estudiantes universitarios de la ciudad de León en Nicaragua. Se midió el índice de masa corporal a través del peso y la estatura y el nivel de conocimiento nutricional. Las prácticas alimentarias fueron medidas con cuestionarios validados con moderadas modificaciones en base al contexto del país. Los datos fueron analizados mediante ANOVA de una vía, chi-cuadrado, prueba t de Student y regresión lineal. Resultados: Se encontró un bajo nivel de conocimiento nutricional y alta prevalencia de exceso de peso. El conocimiento nutricional de los estudiantes universitarios está asociado positivamente con las prácticas alimentarias. Sin embargo, aunque se tenga un máximo de conocimiento no significa un puntaje máximo de diversidad alimentaria. Asimismo, se reportó que las mujeres tienen una diversidad alimentaria ligeramente mayor a los hombres, pero mayor es la diversidad en el grupo que realizan actividad física y aquellos que tienen bajo peso. Por su parte, el conocimiento nutricional está asociado negativamente con el sobrepeso y la obesidad. Conclusión: se comprueba la hipótesis del impacto positivo del conocimiento nutricional en las prácticas alimentarias y la obesidad.

Background: The literature on the impact of food and nutrition education of university students on eating practices is heterogeneous. Studies have revealed that food and nutrition education can change eating habits and choices while others found no association. Objective: Determine the relationship between nutrition knowledge, eating practices, and obesity in Nicaraguan university students. Methods: Analytical cross-sectional study using a sample of 914 university students from the city of León in Nicaragua. The Body Mass Index (BMI) was calculated considering both values of weight and height, and the level of nutrition knowledge and eating practices were measured with validated questionnaires with moderate modifications based on the country context. The data were analyzed using one-way ANOVA, Chi-Square, Student's T-test, and linear regression. Results: A low level of nutrition knowledge and a high prevalence of overweight were found. The nutrition knowledge of university students is positively associated with eating practices. However, even if there is a high degree of nutrition knowledge, it does not mean there is a high dietary diversity score (DDS). Similarly, it was revealed that women have slightly greater dietary diversity scores than men, but greater dietary diversity scores in the group that performs physical activity and those who are underweight. On the other hand, nutrition knowledge is negatively associated with overweight and obesity. Conclusion: the hypothesis of the positive impact of nutrition knowledge on eating practices and obesity is tested.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the response to weight loss guidance in the anthropometric parameters of obesity and overweight infertile patients assisted fertilization treatment (high and low complexity). METHODS: Retrospective cohort study. This survey was conducted in a population of overweight and obese infertile patients. In the first consultation at the assisted reproduction clinic (Human Reproduction Laboratory HC / UFG), obese and overweight patients were weighed, measured and instructed to lose weight and informed that being overweight could reduce the chances of success in the treatment. RESULTS: We analyzed 56 overweight and obese patients admitted for infertility treatment at the Human Reproduction Center HC/UFG. The mean age of overweight and obese patients was 35.78 years, SD 3.70. After the orientation, only 8.92% of patients would achieve the normality rating for BMI, overweight 39.28% (decreased 14.29%), obesity I 37.5%, obesity II 10.71% and obesity III 3.57% (all degrees of obesity increased 1.79%). The mean weight of patients before and after guidance was statistically significant (p<0.0046). The mean values of BMI before and after guidance were also statistically significant (p<0.0038). CONCLUSIONS: Weight loss guidance in this population had no effect on weight loss. On the contrary, the mean weight of patients after guidance was statistically higher than the mean in the first consultation (both weight and BMI). It is suggested that for obese and overweight infertile patients, in addition to guidance for reduction, an appointment with a nutritionist and/or endocrinologist should be immediately scheduled.

RESUMO

Introducción: La actividad física y el estado nutricional son dos componentes fundamentales en el estilo de vida de las personas. Los jóvenes universitarios, al encontrarse expuestos a distintos entornos, son vulnerables a adquirir ciertos hábitos y actitudes que pueden llegar a perjudicar su salud. En República Dominicana se carecen de estos datos, dándole importancia a este estudio, investigando sobre dichos factores modificables. Objetivos: Determinar los factores relacionados al estado nutricional y actividad física en estudiantes universitarios de la provincia Santiago de los Caballeros en el período de mayo-julio 2022. Métodos: Se realizó un estudio descriptivo de tipo corte transversal utilizando fuentes primarias en el periodo 2021-2022 en Santiago, a través de un cuestionario con 33 preguntas, aplicado previo a consentimiento informado, en una muestra de 201 estudiantes seleccionados por un muestreo no probabilístico, de tipo bola de nieve en una población desconocida. Resultados: La mayoría de la población encuestada era de sexo femenino (67.2%), el estado nutricional predominante era aquel con un IMC normal (36.8%), la mayor parte de los universitarios eran inactivos físicamente (41.8%), y los hábitos alimenticios de los mismos eran parcialmente inadecuados (57.2%). Conclusión: La relación entre los factores sociodemográficos y académicos con la actividad física y el estado nutricional no fue estadísticamente significativa. Sin embargo, se evidenció una relación significativa entre la actividad física inactiva y los hábitos alimenticios parcialmente inadecuados de los participantes.

Introduction: Physical activity and nutritional status are two fundamental components of a person's lifestyle. Young university students, being exposed to different environments, are vulnerable to acquiring certain habits and attitudes that may be detrimental to their health. In the Dominican Republic these data are deficient, giving importance to this study, investigating these modifiable factors. Objectives: To determine the factors related to the nu-tritional status and physical activity in university stu-dents of the Santiago de los Caballeros province in the period of May-July 2022. Methods: A descriptive cross-sectional study was ca-rried out using primary sources in the period 2021-2022 in Santiago, using a questionnaire with 33 questions, applied prior to informed consent, in a sample of 201 students selected by a non-probabilistic sampling of snowball type in an unknown population. Results: The majority of the population surveyed was female (67.2%), the predominant nutritional status was normal BMI (36.8%), most of the university students were physically inactive (41.8%), and their eating ha-bits were partially inadequate (57.2%). Conclusion: The relationship between sociodemogra-phic and academic factors with physical activity and nu-tritional status was not statistically significant. Howe-ver, a significant relationship was evidenced between inactive physical activity and partially inadequate eating habits of the participants.

RESUMO

The aim of this study is to analyze the factorial structure of the Multidimensional Body-Self Relations Questionnaire-Appearance Scales (MBSRQ-AS) to determine the adjustment of the study structure proposed in the Spanish short version in a young, non-clinical Chilean population and to evaluate the possible influence of sex, age, and BMI on body image measurement. The sample consisted of 614 Chilean youth (259 male and 355 female) between 15 and 28 years old (M = 18.81; SE = 2.46), from the Metropolitan Region, and four regions of the coast and south-central zone of the country. The average Body Mass Index (BMI) was 22.5 kg/m2 (SD = 3.16). The model fit was evaluated by confirmatory factor analysis (WLSMV) using the following: a model with a single general factor, a model with the five factors of the original version, a five-factor ESEM model, and a MIMIC model analyzed including sex, age, and BMI. The results show that the MIMIC sex, age, and BMI model presents an acceptable fit, observing that four factors, Appearance Orientation (AO), Body Areas Satisfaction (BAS), Overweight Preoccupation (OP), and Self-Classification Weight (SCW), are affected significantly for the sex variable, one for age, Appearance Evaluation (AE), and four for BMI (AE, BAS, OP, and SCW). In conclusion, MBSRQ-AS replicates the five-dimensional structure in a non-clinical sample of young Chileans; however, their scores are not invariant as they depend on sex, age, and BMI.

RESUMO

There are conflicting reports on a possible association between body mass index (BMI) and caries. Given the ongoing worldwide increase in obesity, we undertook a 5-year follow-up study on 201 Mexican schoolchildren to analyse their BMI and dental caries experience. The children's weight and height were recorded, and their BMI was calculated using the WHO tables. Decayed, missing, and filled surfaces in both dentitions (dmf/DMFS) were assessed annually according to WHO criteria by two calibrated researchers (Kappa value 0.92 p < 0.001). The means, standard deviation, an ANOVA, and Student's t-test were calculated to analyse the relationship between the variables. At baseline, the children had an average of 6.5 ± 0.5 years, a BMI of 17.2 ± 3.1 (CI95% 16.8-17.6). Their weight's classifications were 61% normal, 19% obese, 17% overweight, and 3% showed thinness. At the end of the study, their BMI were 20.6 ± 4.4 (CI95% 19.8-21.5), 53% normal, 15% obese, 30% overweight, and 2% thin. The children's dmfs decreased from 5.8 ± 9.2 to 1.8 ± 3.4 and the DMFS increased from 0.07 ± 05 to 1.4 ± 2.3. In this population based on a 5-year follow-up, caries prevalence and incidence were not significantly associated with the BMI. However, schoolchildren with malnutrition had the highest caries indexes.

RESUMO

Objetivo: Determinar la asociación del nivel de antígeno prostático específico (PSA) plasmático y PSA masa según riesgo de padecer enfermedades prostáticas con el perfil antropométrico. Materiales y métodos: Estudio correlacional, de enfoque cuantitativo de dimensión transversal y retrospectiva. La muestra estuvo constituida por 156 historias clínicas de pacientes varones, con pruebas de PSA y datos antropométricos. Para el análisis de la relación de las variables se utilizó la prueba Rho de Spearman, con un nivel de confianza de 95 %. Resultados: La edad promedio de los pacientes fue 67,85±10,83 años y presentaron un valor medio de PSA de 3,57±7,30 ng/mL. El 9,60 % (15 pacientes) tuvo un riesgo bajo de padecer enfermedades prostáticas (PSA = 4,1-9,90 ng/mL); el 5,10 % (8 individuos) mostró riesgo intermedio (PSA= 10-19,90 ng/mL); y el 3, 80 %(6 pacientes) tuvo un riesgo alto (PSA ≥20 ng/mL). El promedio del índice de masa corporal (IMC) fue 26,37±3,81 kg/m2 : 85 pacientes (54,50 %) tenían sobrepeso; y 18 (11,50 %), obesidad. La media de PSA masa fue14,89±30,50 μg; la superficie corporal (SC) se calculó en 3,93± 2,72 m2; y el volumen plasmático fue 4,18± 0,21 L. Se evidenció una correlación positiva muy baja entre el PSA plasmático y la edad (rho = 0,184; p = 0,022), así como con entre la PSA masa y la edad (rho = 0,176; p = 0,028). Se obtuvo una asociación positiva moderada entre el PSA plasmático y la superficie corporal (SC) (rho = 0,456; p = 0,000); y entre el PSA masa y SC (rho = 0,463; p = 0,000). No se encontró relación entre el IMC y el PSA. Conclusiones: Se evidenció la asociación entre el valor de PSA plasmático y PSA masa con el perfil antropométrico, según el riesgo de padecer enfermedades prostáticas, que fue mayor con la superficie corporal y la edad.

Objective: To determine the association between plasma and mass prostate-specific antigen (PSA) levels and the anthropometric profile, taking into account the risk of prostate pathologies. Materials and methods: A correlational, quantitative, cross-sectional and retrospective study conducted with a sample of 156 medical records of male patients with PSA tests and anthropometric data. Spearman's Rho with a 95 % confidence level was used to analyze the relationship between the variables. Results: The average age of the patients was 67.85 ± 10.83 years and their mean PSA value was 3.57 ± 7.30 ng/mL. Fifteen (15) patients (9.60 %) had a low risk (PSA = 4.1 - 9.90 ng/mL), eight (5.10 %) a medium risk (PSA = 10 - 19.90 ng/mL) and six (3.80 %) a high risk (PSA ≥ 20 ng/mL) of developing prostate pathologies. The mean body mass index (BMI) was 26.37 ± 3.81 kg/m2: 85 patients (54.50 %) were overweight and 18 (11.50 %) were obese. The mean mass PSA was 14.89 ± 30.50 μg, the body surface area (BSA) was 3.93 ± 2.72 m2 and the plasma volume was 4.18 ± 0.21 L. A very low positive correlation was evidenced between plasma PSA and age (rho = 0.184; p = 0.022) and between mass PSA and age (rho = 0.176; p = 0.028). There was a moderate positive association between plasma PSA and BSA (rho = 0.456; p = 0.000) and between mass PSA and BSA (rho = 0.463; p = 0.000). No relationship was found between BMI and PSA. Conclusions: The association between plasma and mass PSA levels and the anthropometric profile was demonstrated, taking into account the risk of prostate pathologies, which increased with BSA and age.
