[Integrated mother-child care. Effects on adherence and knowledge of contraceptive methods]. / Atención integrada madre-niño. Efectos sobre adherencia y conocimientos de métodos anticonceptivos.

INTRODUCTION: Scientific evidence suggests that mother-child joint care strategies would facilitate knowledge of contraceptive methods (MAC) and their access. The objective was to evaluate the effect of the Integrated Mother and Child Care Model on adherence and knowledge of CAM in women during the first postpartum semester. METHODS: An intervention study was carried out, 2 groups were formed, GI: intervention group (3 controls up to 6 months postpartum) and GC: control group (one control at 6 months postpartum). The intervention consisted of face-to-face counseling about MAC combined with informative brochures and WhatsApp⌖ messages. Sociodemographic data, gynecological and obstetric history, use and knowledge of contraceptive methods were collected. Adherence to the use and knowledge of MAC were compared in both groups at 6 months postpartum. The analysis was performed using R software version 4.0.3. RESULTS: Thirty-nine women were incorporated into each group. A difference was found in the use of MAC between groups at 6 months (92.3% vs. 64.1%), its use being higher in GI. Significant differences were found in the knowledge of some MAC at 6 months. A higher percentage of women in GI knew about birth control pills (p = 0.009), tubal ligation (p = 0.04) and vasectomy (p = 0.010), compared to GC. DISCUSSION: Early postpartum intervention with various communication and information strategies can be useful to choose the MAC that is considered most appropriate for each woman and its correct use.

El objetivo fue evaluar el efecto del Modelo de atención integrada de la madre y el niño sobre la adherencia y conocimientos de MAC en mujeres durante el primer semestre postparto. Métodos: Se realizó un estudio de intervención, se conformaron 2 grupos, GI: grupo de intervención (3 controles hasta los 6 meses postparto) y GC: grupo control (un control a los 6 meses postparto). La intervención consistió en asesoramiento presencial acerca de MAC combinada con folletería informativa y mensajes de WhatsApp⌖. Se recabaron datos sociodemográficos, antecedentes gineco-obstétricos, uso y conocimientos de MAC. Se comparó la adherencia al uso y el conocimiento de MAC en ambos grupos a los 6 meses post parto. El análisis se realizó mediante el software R versión 4.0.3. Resultados: Se incorporaron 39 mujeres en cada grupo. Se halló una diferencia en el uso de MAC entre grupos a los 6 meses (92.3% vs. 64.1%), siendo más elevado su uso en el GI. Se hallaron diferencias significativas en el conocimiento de algunos MAC a los 6 meses. Un mayor porcentaje de mujeres del GI conocía las pastillas anticonceptivas (p = 0.009), ligadura de trompas (p = 0.04) y la vasectomía (p = 0.010), en comparación con el GC. Discusión: La intervención en el postparto temprano con diversas estrategias de comunicación e información pueden ser útiles para elegir el MAC que se considere más adecuado para cada mujer y su utilización correcta.

Exploring factors associated with obesity in Argentinian children using structural equation modeling.

Habits and behaviors related to obesity risk are strongly associated with the family environment and are affected by socioeconomic factors. Structural equation modeling (SEM) allows us to hypothesize on how the relationships between these factors occur and measure their impact. This study aimed to explore the relationship between family socioeconomic indicators and childhood obesity, mediated by habits linked to energy balance, applying a SEM. A cross sectional study was performed on 861 Argentinian schoolchildren aged 6-12 years, from 2015 to 2016. The model included three latent variables: socioeconomic status, healthy habits, and obesity. Socioeconomic status indicators and healthy habits were surveyed by self-administered parental questionnaires, whereas obesity indicators were evaluated with anthropometry. The applied model showed an acceptable fit (NFI = 0.966; CFI = 0.979; RMSEA = 0.048). Socioeconomic status positively influenced parental education, health insurance, and car possession, while negatively influenced crowding (p < 0.001). Healthy habits significantly influenced physical activity, meals frequency, and sleep hours, while negatively influenced sedentary hours and mother's nutritional status (p < 0.001). Obesity factor positively influenced body mass index, body fat, and waist-to-height ratio (p < 0.001). Finally, socioeconomic status positively influenced health habits, which in turn negatively influenced obesity factor. Healthy habits (especially physical activity and mother's nutritional status) mediated the relationship between socioeconomic status and child obesity. Further research should include other indicators related to diet, eating habits, and physical activity like neighborhood characteristics.

Leptin receptor expression in blood mononuclear cells of lactating women is associated with infant body weight: Potential role as a molecular biomarker.

BACKGROUND: Molecular biomarkers of maternal leptin resistance associated with infant weight are needed. OBJECTIVES: To evaluate gene expression of leptin receptor (LEPR), suppressor of cytokine signalling 3 (SOCS3) and insulin receptor in peripheral blood mononuclear cells (PBMCs) of lactating women and their relationship with infant body weight and adiposity. METHODS: At day 10 postpartum, maternal gene expression in PBMCs as well as leptin and insulin concentrations in plasma and milk were assessed (n = 68). Infant weight and BMI z-scores, skinfolds and arm circumference were obtained at 10 days and/or at 3 months old. RESULTS: In mothers with pre-pregnancy overweight or obesity (OW/OB), LEPR expression was reduced (p = 0.013) whereas plasma and milk leptin and milk insulin concentrations were elevated. LEPR expression was positively related with infant weight z-score (Beta (95% CI): 0.40 (0.17, 0.63), p = 0.001) but not with leptin concentrations. SOCS3 expression was positively related with infant weight z-score (Beta (95% CI): 0.28 (0.04, 0.51), p = 0.024) and arm circumference (Beta (95% CI): 0.57 (0.32, 0.82), p < 0.001). Relationships remained significant after adjusting for maternal and infant confounders. CONCLUSIONS: LEPR and SOCS3 gene expression in PBMCs are novel maternal molecular biomarkers that reflect leptin resistance and are associated with infant body weight and adiposity.

Desarrollo y validación de un índice de calidad de dieta basado en recomendaciones de las guías alimentarias para la población Argentina / Development and validation of a diet quality index based on recommendations of the Dietary Guidelines for the Argentine Population

INTRODUCCIÓN: Los índices de calidad de dieta son herramientas útiles para evaluar patrones alimentarios y adherencia a guías alimentarias. El objetivo fue desarrollar y validar un índice basado en las Guías Alimentarias para la Población Argentina (GAPA). MÉTODOS: Se desarrolló un índice basado en las guías locales, se analizó la validez de contenido por expertos y la validez de constructo y confiabilidad mediante un estudio de corte transversal. Se incluyó a voluntarios adultos sanos y se relevó información general y de consumo de alimentos. Se analizó la capacidad de otorgar puntajes variados y hallar diferencias entre grupos. Se evaluó la correlación entre el puntaje total y cada componente, y con la ingesta energética y de nutrientes. Se exploraron dimensiones subyacentes con análisis de componentes principales. Se analizó la consistencia interna mediante alfa de Cronbach. RESULTADOS: Se desarrolló un Índice de Calidad de Dieta Argentino (ICDAr) que refleja ocho mensajes principales de las guías y se halló buena aceptación por expertos (V de Aiken ≥0,8; p<0,05). El ICDAr demostró amplitud de rango (37,36-86,39) y diferencia entre fumadores y no fumadores (p=0,002). Se halló correlación positiva entre el puntaje total y cada componente y una mejor ingesta de nutrientes, pero no con ingesta energética. Se hallaron múltiples dimensiones subyacentes. El alfa de Cronbach fue 0,49. DISCUSIÓN: El ICDAr es válido para evaluar la calidad de dieta según la adherencia a las GAPA.

Prolonged body weight gain, lifestyle changes and health-related quality of life in children during the COVID-19 pandemic lockdown: A follow-up study.

BACKGROUND: Further investigation is needed to define the impact of long-term pandemic lockdown in children. OBJECTIVES: To examine changes in body mass index z-score (zBMI), lifestyle, Health-Related Quality of Life and proportion of overweight or obesity (OW/OB) in 6- to 9-year-old children in Argentina. METHODS: Observational study with baseline measurements prior to lockdown and follow-up after eight months of strict restrictive measures (November 2020, first visit, n = 144) and after ten months of partial reopening (September 2021, second visit, n = 108). Anthropometric changes from baseline to first visit in lockdown group (LG) were compared with a historical control group (HCG, n = 134). Follow-up visits included anthropometric measures, lifestyle questionnaire and Pediatric Quality of Life Inventory. RESULTS: Change in zBMI was higher in LG [median, IQR: 0.46 (-0.00; 0.83)] vs HCG [median, IQR: 0.02 (-0.31; 0.27)]; p < 0.001, particularly in children with pre-existing OW/OB. In LG, zBMI was higher at first and second visit vs baseline (p < 0.001) and in second visit vs first visit for boys (p = 0.037) but not for girls. The proportion of children with OW/OB increased from baseline (43.5%) to first (56.5%) and second visit (58.3%) (p = 0.029). Unlike girls, the proportion of boys with OW/OB increased from baseline to first and second visit (p = 0.045). Change in zBMI was higher in children with less healthy habits (p < 0.001). CONCLUSIONS: Weight gain continued to increase in boys when lockdown measurements were eased, although sedentary behaviors decreased and quality of life improved, indicating that the effects of pandemic lockdown could be difficult to reverse.

Resumen: Los hábitos y comportamientos relacionados con el riesgo de obesidad están fuertemente asociados al entorno familiar y se ven afectados por factores socioeconómicos. El modelo de ecuaciones estructurales (MEE) permite plantear hipótesis sobre cómo se dan las relaciones entre estos factores y medir su impacto. El objetivo del presente estudio fue explorar la relación entre los indicadores socioeconómicos familiares y la obesidad infantil, mediada por hábitos relacionados con el balance energético, aplicando un MEE. Se realizó un estudio transversal con 861 escolares argentinos de 6 a 12 años entre 2015 y 2016. El modelo incluyó tres variables latentes: nivel socioeconómico, hábitos saludables y obesidad. Los indicadores nivel socioeconómico y hábitos saludables se midieron mediante cuestionarios autoadministrados a los padres, mientras que los indicadores de obesidad se obtuvieron mediante antropometría. El modelo aplicado presentó un ajuste aceptable (NFI = 0,966; CFI = 0,979; RMSEA = 0,048). El nivel socioeconómico influyó positivamente en la escolaridad de los padres, en el plan de salud y en el hecho de tener automóvil, mientras que influyó negativamente en el hacinamiento (p < 0,001). La variable hábitos saludables influyó significativamente en la actividad física, en la frecuencia de las comidas y en las horas de sueño, pero influyó negativamente en las horas sedentarias y en el estado nutricional materno (p < 0,001). El factor obesidad influyó positivamente en el índice de masa corporal, en la grasa corporal y en la razón cintura/talla (p < 0,001). Finalmente, el nivel socioeconómico influyó positivamente en los hábitos saludables, que, a su vez, influyeron negativamente en la obesidad. Los hábitos saludables, en especial la actividad física y el estado nutricional materno, moderan la relación entre el nivel socioeconómico y la obesidad infantil. Las nuevas investigaciones deberían incluir otros indicadores relacionados con la dieta, con los hábitos alimentarios y con la actividad física, así como con las características del vecindario.

Resumo: Hábitos e comportamentos relacionados ao risco de obesidade estão fortemente associados ao ambiente familiar e afetados por fatores socioeconômicos. A modelagem de equações estruturais (MEE) permite levantar hipóteses sobre como ocorrem as relações entre esses fatores e medir seu impacto. O objetivo do presente estudo foi explorar a relação entre os indicadores socioeconômicos familiares e a obesidade infantil, mediada por hábitos ligados ao balanço energético, aplicando uma MEE. Um estudo transversal foi realizado com 861 escolares argentinos de 6 a 12 anos entre 2015 e 2016. O modelo incluiu três variáveis latentes: nível socioeconômico, hábitos saudáveis e obesidade. Os indicadores do nível socioeconômico e de hábitos saudáveis foram medidos por meio de questionários autoaplicáveis aos pais, enquanto os indicadores de obesidade foram obtidos por meio de antropometria. O modelo aplicado apresentou um ajuste aceitável (NFI = 0,966; CFI = 0,979; RMSEA = 0,048). O nível socioeconômico influenciou positivamente a escolaridade dos pais, o plano de saúde e a posse de automóvel, enquanto influenciou negativamente a aglomeração (p < 0,001). A variável hábitso saudáveis influenciou significativamente a atividade física, a frequência das refeições e as horas de sono, mas influenciou negativamente as horas sedentárias e o estado nutricional materno (p < 0,001). O fator obesidade influenciou positivamente o índice de massa corporal, a gordura corporal e a relação cintura/estatura (p < 0,001). Finalmente, o nível socioeconômico influenciou positivamente os hábitso saudáveis, que por sua vez influenciou negativamente a obesidade. Hábitos saudáveis, especialmente atividade física e estado nutricional materno, mediam a relação entre nível socioeconômico e obesidade infantil. Novas pesquisas devem incluir outros indicadores relacionados à dieta, hábitos alimentares e atividade física, como características da vizinhança.

Tendencia de cesáreas en entidades privadas de la provincia de Buenos Aires, Argentina (2017-2021) / Cesarean section trends in private entities in the province of Buenos Aires, Argentina (2017-2021)

Resumen OBJETIVO: Evaluar las tasas de cesárea en la finalización de embarazos registrados en el sector privado de la Obra Social de la provincia de Buenos Aires (Instituto de Obra Médico Asistencial) entre los años 2017 a 2021. MATERIALES Y MÉTODOS: Estudio analítico y descriptivo de cesáreas registradas en el Sistema de Modulación Centro Único de Auditoría y Fiscalización IOMA (CUAFI) de las 13 regiones sanitarias de la provincia de Buenos Aires. Se describen los porcentajes de cesárea por año y por región sanitaria. RESULTADOS: Se registraron 75,244 partos únicos. En el año 2017 el porcentaje de cesáreas se incrementó de 69.0% (12,600 cesáreas de 18,258 partos) a 73.6% (8,232 cesáreas de 11,180 partos) en 2021. Los mayores porcentajes de cesárea se registraron en la Región IV (83.6%), la Región XIV (81.7%) y Región X (78.9%). CONCLUSIÓN: El alto porcentaje de cesáreas registrado y el incremento en los últimos años muestra la necesidad de diseñar intervenciones para reducir su tasa. Será importante contar con información de sus indicaciones y explorar intervenciones destinadas al personal de salud y a las mujeres para reducir su práctica.

Abstract OBJECTIVE: To evaluate the rates of caesarean section in the termination of pregnancies registered in the private sector of the Obra Social of the province of Buenos Aires (Instituto de Obra Médico Asistencial) between 2017 and 2021. MATERIALS AND METHODS: Analytical and descriptive study of caesarean sections registered in the Modulation System of the IOMA Single Audit and Control Centre (CUAFI) of the 13 health regions of the province of Buenos Aires. The percentages of caesarean sections per year and per health region are described. RESULTS: 75,244 singleton deliveries were registered in the private sector of the Instituto de Obra Médico Asistencial. In 2017, the percentage of caesarean sections increased from 69.0% (12,600 caesarean sections out of 18,258 deliveries) to 73.6% (8,232 caesarean sections out of 11,180 deliveries) in 2021. The highest caesarean section rates were recorded in Region IV (83.6%), Region XIV (81.7%) and Region X (78.9%). CONCLUSION: The high percentage of caesarean sections recorded and the increase in recent years shows the need to design interventions to decrease the rate. It is important to have information on the indications for caesarean section and to explore interventions aimed at health personnel and women to reduce the rate.

Dietary Patterns in the Argentinian Population and Their Association With Sociodemographic Characteristics: Results From the ELANS Study (2014-2015).

Aim: To describe dietary patterns in the Argentinian population and their association with sociodemographic characteristics. Methods: Cross-sectional analysis of Argentina's food consumption and sociodemographic data of 1,266 men and women between 15 and 65 years from the Latin American Study of Nutrition and Health carried out between March 2014 and December 2015. Dietary patterns were identified by using factor analysis and median factor scores were calculated for gender, age, region, body mass index (BMI), socioeconomic, education, and physical activity categories. Results: Five dietary patterns were identified. Western, Local Western, and Rural were generally characterized by high consumptions of animal fats, sugar-sweetened beverages, meats or processed meats, pizza and empanadas, sweets, pastries, and low consumption of fruits and vegetables. Traditional pattern was mainly characterized by consumption of oils, starchy vegetables, and red meat and Sweet Prudent by milk and yogurt, vegetables, fruit, artificially sweetened beverages, sweets, and cookies. Higher adherence to the Sweet Prudent pattern was observed in women, in people who meet physical activity guidelines and higher socioeconomic and educational levels. Higher adherence to traditional pattern was only observed for men. Higher adherence to the rest of the patterns was observed mostly by men, young, leaner, lower socioeconomic, and educational levels, not meeting physical activity guidelines, from the metropolitan area of Buenos Aires or northern regions. Conclusion: Food consumption in Argentina is expressed in a diversity of dietary patterns. Men, younger, and sedentary individuals, with lower socioeconomic and educational level, from the metropolitan area of Buenos Aires and northern regions, seem to have higher adherence to least healthy dietary patterns.

Consequences of Lockdown During COVID-19 Pandemic in Lifestyle and Emotional State of Children in Argentina.

The implications of the coronavirus disease (COVID-19) lockdown measurements and social isolation in children and their parents are still unknown. The aims of this study were to examine the impact of COVID-19 lockdown on emotional state, feelings and lifestyle of children and their parents, to explore the association between parental characteristics and child well-being and to examine whether the impact of lockdown depends on socio-economic status. Parents completed an online survey including data about socio-demographic information, parent and child feelings and lifestyle during lockdown. Logistic regression and correlation analysis were used to establish associations between variables. In total, 814 parents with children between 4 and 11 were included in the study. According to parents, 69.5% of the children showed changes in their emotional state, 55.3% altered their routine and 62.6% showed sleep disorders. Families with lower socio-economic status were more worried about health, shortage of food and household income (p < 0.01). Parent and children concern about food/essential items were highly associated [OR (CI 95%) 13.0 (6.81, 26.5), p < 0.01]. Adverse children's emotional state was associated with parental feeling of loneliness (r = 0.35) and inversely associated with keeping a routine (r = -0.11). Sleep changes were inversely associated with keeping a routine and having a balcony/garden (r = -0.53 and -0.16). We conclude that lockdown affected emotional state and lifestyle of children and parents, which were strongly related. Routine and positive parental attitude supported children's well-being. Economic issues were an important concern in families with lower socio-economic status. Our findings can help to promote child health during lockdown.

Plasma levels of ghrelin, des-acyl ghrelin and LEAP2 in children with obesity: correlation with age and insulin resistance.

OBJECTIVE: The octanoylated peptide hormone ghrelin regulates appetite and glycaemic control. Des-acyl ghrelin abolishes some effects of ghrelin, but does not bind to ghrelin receptor. LEAP2 is a novel ligand for ghrelin receptor that blocks the effects of ghrelin. Some evidences show that plasma levels of these peptides are altered in adults with obesity, but their levels in childhood obesity remain poorly studied. Therefore, the objective of this study was to assess fasting plasma levels of ghrelin, des-acyl ghrelin and LEAP2 in children with normoweight, overweight/obesity and their association with different anthropometric and metabolic variables. DESIGN: A total of 42 females and 40 males, ages 3-12 years old were enrolled as a cross-sectional cohort. RESULTS: Plasma levels of des-acyl ghrelin and LEAP2 (but not ghrelin) were lower and ghrelin/des-acyl ghrelin ratio was higher in children with overweight/obesity. Des-acyl ghrelin negatively correlated with age, BMI z-score, insulin and HOMA index, and the correlations were stronger in children with overweight/obesity. LEAP2 levels negatively correlated with BMI z-score. No gender differences were found. CONCLUSIONS: Our findings suggest that ghrelin tone is increased in childhood obesity, due to a decrease on plasma levels of des-acyl ghrelin and LEAP2, and that des-acyl ghrelin is associated to insulin resistance, particularly in children with overweight/obesity.
