Children's perception of food parenting practices: adaptation and validation of the comprehensive feeding practices questionnaire in Chilean adolescents

Introduction

Assessment of the Comprehensive Feeding Practices Questionnaire in adolescents (CFPQ-Teen) is still limited, with no evaluation of the measurement invariance. The participants comprised 473 Chilean adolescents of both sexes from dual-income nuclear families. The aims of this study were: (1) to adapt to Spanish and validate a model of five-factor version the CFPQ-Teen; (2) to examine the psychometric properties, (3) to evaluate the measurement invariance according to the adolescents' gender; and (4) to compare the scores of each factor between female and male adolescents.

Methods

The instrument was translated, back-translated, and adapted from the CFPQ-Teen, confirming the equivalence, conceptual, and face validity in a pilot sample of 40 adolescents. An exploratory factor analysis was performed on the five-factor model of the CFPQ-Teen: Monitoring, Adolescent Control, Restriction for weight control, Parental Modeling, and Environment. The Environment factor was eliminated as a result.

Results

The confirmatory factor analysis presented good reliability, convergent, discriminant, and concurrent validity values. In addition, medium to high goodness-of-fit levels were obtained by eliminating an item from the Adolescent Control factor. These results confirm a final 20-item model representing four factors. The multigroup invariance analysis of the measurement model verified configural, metric, scalar, and partial strict invariance. No significant differences were found between females and males in the scores on the four factors.

Discussion

These results enable comparisons by sex on the perceptions of Food Parenting Practices from the analyzed factors, primarily within the context of the Chilean sample.

Intra- and Inter-Individual Associations of Family-to-Work Conflict, Psychological Distress, and Job Satisfaction: Gender Differences in Dual-Earner Parents during the COVID-19 Pandemic

The COVID-19 pandemic changed the work-family interface dynamics in some families. For couples who kept earning a double income during the pandemic, their family demands may entail a loss of psychological resources that affect the work domain. This study explored the intra-individual and inter-individual (crossover) direct and indirect effects of family-to-work conflict (FtoWC) on psychological distress and job satisfaction in a non-probabilistic sample of 860 different-sex dual-earner parents with adolescent children from Temuco and Rancagua, Chile. Mothers and fathers answered an online questionnaire measuring FtoWC, the Depression, Anxiety, and Stress Scale, and the Overall Job Satisfaction Scale. The data were analyzed using the actor-partner interdependence model with structural equation modeling. Results showed that a higher FtoWC is linked to greater psychological distress and lower job satisfaction in both parents. In contrast, psychological distress is directly linked to lower job satisfaction in fathers. In both fathers and mothers, they and their partners' FtoWC were indirectly linked to lower job satisfaction via the fathers' psychological distress. These findings indicate the need for gender-sensitive social and labor policies aimed at reducing the conflict between family and work to increase job satisfaction in both parents and reduce psychological distress, particularly in fathers.

The Coronavirus Anxiety Scale: Cross-national measurement invariance and convergent validity evidence

Coronavirus Anxiety Scale (CAS) is a widely used measure that captures somatic symptoms of coronavirus-related anxiety. In a large-scale collaboration spanning 60 countries (Ntotal = 21,513), we examined the CAS's measurement invariance and assessed the convergent validity of CAS scores in relation to the fear of COVID-19 (FCV-19S) and the satisfaction with life (SWLS-3) scales. We utilized both conventional exact invariance tests and alignment procedures, with results revealing that the single-factor model fit the data well in almost all countries. Partial scalar invariance was supported in a subset of 56 countries. To ensure the robustness of results, given the unbalanced samples, we employed resampling techniques both with and without replacement and found the results were more stable in larger samples. The alignment procedure demonstrated a high degree of measurement invariance with 9% of the parameters exhibiting noninvariance. We also conducted simulations of alignment using the parameters estimated in the current model. Findings demonstrated reliability of the means but indicated challenges in estimating the latent variances. Strong positive correlations between CAS and FCV-19S estimated with all three different approaches were found in most countries. Correlations of CAS and SWLS-3 were weak and negative but significantly differed from zero in several countries. Overall, the study provided support for the measurement invariance of the CAS and offered evidence of its convergent validity while also highlighting issues with variance estimation.

Profiles of older adults according to their life and food-related life satisfaction during the COVID-19 pandemic: the importance of the social environment

Introduction

Older adults are a highly heterogeneous population, as individuals of the same age can show considerable variations in personal characteristics and living conditions. Risk and protective factors for older adults' subjective wellbeing during the COVID-19 pandemic can be explored by examining how life satisfaction, food-related life satisfaction, and associated variables coexist among these individuals. On this basis, this study aimed to identify older adult profiles based on their levels of life and food-related life satisfaction; to characterize these profiles by diet quality, social support, financial wellbeing, and sociodemographic characteristics; and to identify variables associated with higher life and food-related life satisfaction.

Methods

The sample included 1,371 institutionalized and non-institutionalized individuals over the age of 60, from four cities in Chile. Participants answered a survey, either online or face to face, with questions about life and food-related life satisfaction, perceived social support from family, friends, and others, food quality, financial wellbeing/distress, sociodemographic characteristics, and prior COVID-19 infection.

Results

Using a latent profile analysis, we identified three profiles of older adults: Profile 1: Unsatisfied with their life, somewhat satisfied with their food-related life (5.40%); Profile 2: Somewhat satisfied with their life, satisfied with their food-related life (65.06%); Profile 3: Extremely satisfied with their life and food-related life (29.54%). Profiles differed by residence (institutionalized vs. independent), age, marital status, social support, financial wellbeing, COVID-19 infection, and city of residence.

Discussion

The patterns of association between life and food-related satisfaction and related variables indicate conditions of vulnerability and protection related to living conditions, the social dimensions of food consumption, and social support. These results underscore the need for identifying groups of older adults based on diverse characteristics and conditions outside of chronological age.

Revisiting the link between domain satisfaction and life satisfaction during the COVID-19 pandemic: Job-related moderators in triadic analysis in dual-earner parents with adolescent children

Introduction

Research has evaluated the impact of COVID-19 pandemic and lockdowns on individuals' life satisfaction, but wellbeing interrelations between family members in this context have been less explored. This study examined the spillover and crossover effects of one parent's job satisfaction (JS), satisfaction with family life (SWFaL) and satisfaction with food-related life (SWFoL) on their own, their partner's, and their adolescent children's life satisfaction (LS), and the influence of adolescents' SWFaL and SWFoL on their own and their parents' LS, in dual-earner families with adolescents. The moderating role of job-related variables of both parents were also explored.

Methods

Questionnaires were administered to 860 dual-earner parents with adolescents in two cities in Chile during 2020. Mothers and fathers answered the Overall Job Satisfaction Scale and the three family members answered the Satisfaction with Life Scale, the Satisfaction with Family Life Scale and the Satisfaction with Food-related Life Scale.

Results

Using the Actor-Partner Interdependence Model and structural equation modeling, we found that fathers' LS was positively associated with their own JS, SWFaL and SWFoL (spillover), and negatively with adolescents' SWFoL (crossover). Likewise, mothers' LS was positively associated with their own JS, SWFaL and SWFoL (spillover), with fathers' and adolescents' SWFaL, and negatively with adolescents' SWFoL. Adolescents' LS was positively associated with their own SWFaL and SWFoL (spillover), and with their fathers' JS, and negatively with their fathers' SWFoL. JS showed gendered patterns in spillover and crossover associations. Parents' type of employment, mothers' working hours and city of residence moderated some spillover and crossover associations for father-mother and parent-adolescent dyads.

Discussion

These findings suggest that, for dual-earner parents with adolescents, improving individuals' LS requires interventions that should be carried out not individually, but at a family level.

Measurement invariance of the comprehensive feeding practices questionnaire in dual-earner parents with adolescent children in Chile

The Comprehensive Feeding Practices Questionnaire (CFPQ) has been evaluated in international studies, but the evaluation of its psychometric properties in Spanish, and in particular for parents of adolescents is still limited, and the invariance of measurement according to gender has not been evaluated. Therefore, the objectives of this study were: (1) To adapt the five-factor model of the CFPQ instrument to Spanish; (2) To examine the psychometric properties of this adaptation; and (3) To evaluate the measurement invariance of the model to verify the equivalence of measurement of the perceptions of food parenting practices between mothers and fathers belonging to nuclear, dual-earner families with adolescent children. Participants were 946 mothers and fathers from Southern Chile. Results showed that the conceptual equivalence for the CFPQ was achieved. An exploratory factor analysis was performed for a five-factor model: Monitoring, Child control, Restriction for weight control, Modeling and Environment. Horn's parallel analysis identified four factors, while factor loading analysis determined the removal of the environment factor. Confirmatory factor analysis presented good reliability values. Convergent and discriminant validity was confirmed, and medium-to-high levels of goodness of fit were obtained, eliminating two items. Results supported a final model of four factors and 19 items. Multigroup analysis of the measurement model verified the configural and metric invariance between fathers and mothers, while the scalar and strict partial invariance was verified. These findings are a relevant guide to measure factorial scores in the four-factor model of the CFPQ, establishing a characterization of feeding practices of parents and adolescents.

Conflicto trabajo-familia, síntomas emocionales negativos y satisfacción familiar en mujeres con trabajo remunerado durante la pandemia de COVID-19

Introducción: Durante la pandemia por COVID-19 las medidas de contención implementadas a nivel mundial han transformado la vida familiar y la forma de trabajar de las mujeres, profundizando desigualdades preexistentes tanto en el trabajo como en la familia. Método: Mediante ecuaciones estructurales se exploraron las relaciones entre el conflicto trabajo-familia, los síntomas emocionales negativos y la satisfacción familiar en mujeres de familias con doble ingreso. Se administraron cuestionarios a 430 mujeres que trabajaban de forma remunerada con al menos un hijo adolescente en Rancagua, Chile, quienes respondieron las dimensiones conflicto del trabajo a la familia y conflicto de la familia al trabajo de la Escala Interfaz Trabajo Familia; la Escala de Depresión, Ansiedad y Estrés (DASS-21); y la Escala de Satisfacción con la Vida Familiar. Resultados: El conflicto trabajo-familia, en ambas direcciones, se asoció positivamente con síntomas emocionales negativos, los cuales, a su vez, se relacionaron negativamente con la satisfacción familiar. El conflicto de la familia al trabajo se relacionó negativamente de forma directa con la satisfacción familiar, mientras que los síntomas emocionales negativos mostraron un rol mediador entre el conflicto trabajo-familia y la satisfacción familiar. Conclusiones: Nuestros hallazgos sugieren que, para mejorar la satisfacción familiar en situaciones de crisis, son necesarias intervenciones para mitigar las demandas laborales y familiares, así como reducir emociones negativas como depresión, ansiedad y estrés en mujeres madres que trabajan con remuneración.

Contributions of Work-to-Family Enrichment to Parental Food Monitoring and Satisfaction with Food-Related Life during the COVID-19 Pandemic in Dual-Earner Parents and Their Adolescent Children

Evidence shows that numerous family-related variables influence parents’ use of different food parenting practices (FPP), but less is known about the influence of parents’ work-related variables on their use of FPP, and their own and their children’s outcomes in the food domain. To fill this gap, the present study explored intra-individual and inter-individual effects between work-to-family enrichment (WtoFE), parents’ monitoring practices, the adolescent’s perception of their parents’ monitoring practices, and the three family members’ satisfaction with food-related life (SWFoL), in different-sex dual-earner parents with adolescent children. The mediating role of monitoring between WtoFE and SWFoL was also tested. A sample of 430 different-sex dual-earner parents and one of their adolescent children (average age 13.0 years, 53.7% female) were recruited in Rancagua, Chile, during March and June 2020. The three family members answered the monitoring dimension of the Compressive Feeding Practices Questionnaire and the Satisfaction with Food-Related Life Scale. Parents answered a measure of WtoFE based on the Work−Home Interaction Survey. Analyses were conducted using the Actor−Partner Interdependence Model and structural equation modelling. Results showed a positive association between WtoFE and SWFoL, directly (p < 0.001) and through monitoring in fathers (95% confidence interval [0.010, 0.097], actor effect). The father’s (p = 0.042) and mother’s (p = 0.006) WtoFE was positively associated with their adolescent’s SWFoL (partner effects). The father’s (p = 0.002) and mother’s (p = 0.036) WtoFE were positively associated with their own monitoring (actor effect), while only the father’s WtoFE (p = 0.014) was positively associated with the adolescent’s perception of their parents’ monitoring (partner effect). The father’s (p = 0.018) and mother’s (p = 0.003) monitoring, as well as the adolescents’ perception of their parents’ monitoring (p = 0.033), were positively associated with their own SWFoL (actor effects), while the mother’s monitoring (p = 0.043) was also associated with the father’s SWFoL (partner effects). Findings suggest that both parents’ WtoFE improved their monitoring practices, which, in turn, improved their own SWFoL and their adolescent child’s SWFoL. Policymakers and organizations must aim to promote the WtoFE of working parents.

Behavior without beliefs: Profiles of heteronormativity and well-being among heterosexual and non-heterosexual university students in Chile

Heteronormativity comprises essentialist, binary beliefs about sex and gender, and normative behaviors derived from those beliefs. There is scarce literature on how heteronormative attitudes and well-being variables are concurrent among individuals who are heterosexual or gay, lesbian, bisexual, and of other queer sexual identities (LGBQ). The objective of this study was to distinguish profiles of university students based on essentialism and normative behavior, two dimensions of heteronormativity, and to characterize these groups by sexual orientation and gender, perceived social support, physical and mental health, and life satisfaction. A sample of 552 university students in Temuco, Chile, responded to an online questionnaire consisting of sociodemographic questions, the Scale of Heteronormative Attitudes and Beliefs, the Life Satisfaction Scale, the Health-Related Quality of Life Index, and the Multidimensional Scale of Perceived Social Support. We used Latent profile analysis to distinguish profiles based on significant score differences in Essentialism and Normative behavior. We identified four heteronormativity profiles: High heteronormativity (34.85%), with a significant proportion of heterosexuals and men; Low heteronormativity (25.59%), comprising a significant proportion of students who were non-binary, and LGBQ; Heteronormativity focused on normative behavior (20.42%), with a significant proportion students who were men or non-binary, and who were lesbian, gay or bisexual or preferred not to disclose their sexual orientation; and Heteronormativity focused on essentialism (19.14%), with a significant proportion of heterosexuals and women, and individuals who preferred not to disclose their sexual orientation. The four profiles differed in the proportions of students by faculty and area of residence (urban/rural), and by life satisfaction, self-perceived mental health, and perceived social support. These results show that patterns of association between heteronormativity and subjective well-being are heterogeneous among heterosexual and non-heterosexual individuals. Some of these patterns may respond to the COVID-19 pandemic, which has disrupted daily life and social dynamics. These findings expand our understanding of advantageous and disadvantageous conditions associated with maintaining heteronormativity attitudes, particularly among non-heterosexual individuals.

Job satisfaction as a mediator between family-to-work conflict and satisfaction with family life: a dyadic analysis in dual-earner parents

Family-to-work conflict has received less attention in the literature compared to work-to-family conflict. This gap in knowledge is more pronounced during the COVID-19 pandemic, despite the documented increase in family responsibilities in detriment of work performance, particularly for women. Job satisfaction has been identified as a mediator between the family and work domains for the individual, but these family-to-work dynamics remain unexplored at a dyadic level during the pandemic. Therefore, this study tested the relationship between family-to-work conflict and job and family satisfaction, and the mediating role of job satisfaction between family-to-work conflict and family satisfaction, in dual-earner parents. A non-probability sample of 430 dual-earner parents with adolescent children were recruited in Rancagua, Chile. Mothers and fathers answered an online questionnaire with a measure of family-to-work conflict, the Job Satisfaction Scale and Satisfaction with Family Life Scale. Data was analysed using the Actor-Partner Interdependence Model with structural equation modelling. Results showed that, for individuals, a higher family-to-work conflict is linked to lower satisfaction with both their job and family life, and these two types of satisfaction are positively associated with one another. Both parents experience a double negative effect on their family life satisfaction, due to their own, and to their partner's family-to-work conflict; however, for fathers, this effect from their partner occurs via their own job satisfaction. Limitations and implications of this study are discussed, indicating the need of family-oriented workplace policies with a gender perspective to increase satisfaction in the family domain for workers and their families.

Effects of work-to-family enrichment on psychological distress and family satisfaction: A dyadic analysis in dual-earner parents

Resources that individuals acquire at work can have significant effects on their own well-being and family satisfaction, and on those of their closest family relations. Following the conservation of resources theory, this study examined the effects of work-to-family enrichment (WFE) on psychological distress (depression, anxiety, and stress) and family satisfaction (SWFaL) in different-gender dual-earner parents. The sample consisted of 473 couples - mother and father - from Temuco, Chile, who answered the Work-Family Interface scale, the Depression, Anxiety and Stress Scale, and the Satisfaction with Family Scale. The analysis was conducted using the Actor-Partner Interdependence Model (APIM). Results showed that WFE was positively associated with SWFaL for both mothers and fathers (actor effects), whereas higher WFE was linked to lower psychological distress only in fathers. For mothers and fathers, psychological distress was negatively associated with their own (actor effects) and the other parent's SWFAL (partner effects). The mediating role of psychological distress was found only for fathers' WFE and their SWFaL. These results indicate that resources from work can increase family satisfaction for both fathers and mothers in dual-earner couples with adolescent children. However, in these couples, fathers acquire affective resources (positive mood) that reduce their own psychological distress, while mothers acquire skills (managing time at home more efficiently) that they invest directly in the family domain.

Relationships between diet quality, food satisfaction and life satisfaction in mother-adolescent dyads

This study examined the relationships between diet quality, satisfaction with food-related life and life satisfaction in mother-adolescent dyads. The sample consisted of 470 mother-adolescent dyads in Temuco, Chile. Mothers and adolescents responded to the Adapted Healthy Eating Index, Satisfaction with Life Scale, and the Satisfaction with Food-related Life scale. Data was analyzed using the Actor-Partner Interdependence Model (APIM) and Structural Equation Modelling (SEM). Diet quality was associated with satisfaction with food-related life, which related to life satisfaction in mothers and adolescents. We did not find direct relationships between diet quality and life satisfaction for either dyad member. Adolescents' diet quality negatively affected their mothers' satisfaction with food-related life; adolescents' food-related life was positively associated with their mothers' life satisfaction. The mothers' satisfaction with food-related life played a mediating role between their own diet quality and life satisfaction. Mothers and their adolescent children affect one another in their dietary patterns and life satisfaction. Child-to-mother influences on food-related experiences show that adolescents' satisfaction with food-related life improves their own and their mothers' life satisfaction. Interventions to promote healthy eating habits must be addressed to both mothers and their adolescent children.

Family profiles based on family life satisfaction in dual-earner households with adolescent children in Chile

Research has stressed the importance of the family domain for the individual's well-being, but the heterogeneity/homogeneity of satisfaction with family life between and within families have not previously assessed. This study identifies family profiles based on the level of family life satisfaction in mother-father-adolescent triads and determines whether profiles differ in terms of the three family members' perceived family support, importance assigned to the family, both parents' work-life balance and mental health, and the household's economic situation. The sample was composed of 303 families of different-sex dual-earner parents with one child aged between 10 and 17 years, from Temuco, Chile. A Latent Profile Analysis was used to identify three profiles: Families with low family satisfaction (17.80%), Families with medium family satisfaction (68.14%), and Families with high family satisfaction (14.06%). Profiles also differed in the three family members' perceived family support and importance assigned to the family, both parents' work-life balance and mental health, and in the household's income. Mothers, fathers, and adolescents in these profiles also differed from one another in these variables. The main variable related to the family members' satisfaction with family life was the parents' mental health problems. Family life satisfaction in dual-earner couples with adolescent children is heterogenous, and these profiles draw attention to indicators of parent-child well-being. Families with lower levels of family satisfaction require particular attention in research and interventions, as these families may report a lower household income, and the parents may experience higher rates of depression, anxiety, and stress, and diverging levels of work-life balance.

Parents' Modeling During the COVID-19 Pandemic: Influences on Family Members' Diet Quality and Satisfaction With-Food-Related Life in Dual-Earner Parents With Adolescent Children

Reciprocal family influences in the food domain have been little explored, particularly during the COVID-19 pandemic. To fill in this gap, this study explored actor and partner effects between parents' food modeling and parents' and their adolescent children's diet quality and satisfaction with food-related life (SWFoL); and the mediating role of diet quality between modeling and SWFoL. This study used a cross-sectional design. A sample of 430 different-sex dual-earner parents and one adolescent child were recruited in Rancagua, Chile, between March and June 2020. Parents answered the modeling dimension of the Comprehensive Feeding Practices Questionnaire. Parents and adolescents answered the Adapted Healthy Eating Index (AHEI) and the SWFoL Scale. Analyses were conducted using the Actor-Partner Interdependence Model and structural equation modeling. Results showed that one parent's modeling enhanced diet quality for themselves, their partner, and the adolescents. Parents' modeling was associated with their own SWFoL, directly and via their own diet quality. There were positive associations between mothers' modeling and adolescents' SWFoL; between mothers' diet quality and fathers' SWFoL; and between mothers' modeling and fathers' SWFoL via the fathers' diet quality. Parents' modeling can improve the three family members' diet quality, while mothers' modeling and diet quality showed to improve fathers' and adolescents' SWFoL.

Family-to-work enrichment associations between family meal atmosphere and job satisfaction in dual-earner parents

Research on factors related to job satisfaction in parents has mainly focused on work-related variables, paying less attention to family events that may provide parents with resources to invest in the work domain. To contribute to this body of knowledge, this study examined the associations between family meal atmosphere and job satisfaction in dual-earner parents with adolescent children, and tested the mediating role of family-to-work enrichment (FtoWE) between family meal atmosphere and job satisfaction. Questionnaires were administered to 473 different-gender dual-earner parents in Temuco, Chile. Participants answered the Project-EAT Atmosphere of family meals scale, three items that measure FWE from the Work-Home Interaction Survey, and the Overall Job Satisfaction Scale. Analyses were conducted using the Actor-Partner Interdependence Model and structural equation modelling. A positive association was found from family meal atmosphere to job satisfaction, directly and via FtoWE in fathers, and only via FtoWE in mothers. No associations were found for these variables between parents, as, one parent's perception of a pleasant family meal atmosphere is positively associated with their own FtoWE and job satisfaction, but not with those of the other parent. These findings suggest policymakers and organizations to account for workers' experiences in the family domain to improve satisfaction in the work domain.

Spillover-crossover effects for satisfaction with food-related life in dual-earner parents with adolescent children

This study aimed to examine spillover and crossover associations between parents’ family support, work-life balance, and satisfaction with food-related life in dual-earner parents with adolescent children. The mediating role of work-life balance in these relationships was also explored. This is a cross-sectional study with mothers, fathers and adolescent children from Temuco, Chile as participants. The sample comprised 303 families of different-sex dual-earner parents with adolescent children (mean age 13.3, 51.5% female). The Actor-Partner Interdependence Model (APIM) was used to examine spillover (actor effects) and crossover (partner effects) associations between family members. Positive spillover effects were found for both parents (p < 0.001). Crossover effects were found from fathers’ support and work-life balance, respectively, to mothers’ work-life balance and satisfaction with food-related life (p < 0.001). No crossover effects were found between parents’ work-life balance and their children’s satisfaction with food-related life (p > 0.1). Work-life balance had a complete mediating role between parents’ family support and satisfaction with food-related life in mothers (bias-corrected, 95%CI: -0.191; 0.093), and a partial role in fathers (bias-corrected, 95%CI: 0.007; 0.295). Spillover and crossover effects between parents’ family support and work-life balance in dual-earner parents are associated with increased satisfaction with food-related life. Interventions to promote food-related life satisfaction in dual-earner parents should address both the work and other life roles that these parents fulfill.

Relaciones directas e indirectas entre apoyo familiar, comidas familiares, satisfacción familiar y vital en trabajadores

Introducción: Para las personas con trabajo remunerado, la familia es una fuente importante de recursos psicológicos que contribuyen a su bienestar. Se hipotetiza que el apoyo familiar es un factor protector de la satisfacción vital de la persona, de modo directo y a través de otras variables como las comidas familiares y la satisfacción con la vida familiar. En ese sentido, el objetivo de este estudio fue examinar el papel mediador en serie de la atmósfera de las comidas familiares y la satisfacción con la vida familiar en la relación entre el apoyo familiar y la satisfacción con la vida, en mujeres y hombres con trabajos remunerados. Método: Se aplicó la Escala de Satisfacción con la Vida, Escala Multidimensional de Apoyo Social Percibido, Escala Atmósfera de las Comidas Familiares y Escala de Satisfacción con la Vida Familiar, a una muestra de 236 mujeres y 236 hombres con trabajo remunerado en Temuco, Chile. El análisis estadístico consideró un modelo de mediación en serie con un Intervalo de Confianza del 95%. Resultados: El apoyo familiar y la satisfacción con la vida correlacionaron de forma directa y estadísticamente significativa. Además, se obtuvo un efecto indirecto significativo de la atmósfera de las comidas familiares y la satisfacción con la vida familiar, en la relación entre el apoyo familiar y la satisfacción con la vida. La atmósfera de las comidas familiares y la satisfacción con la vida familiar son mediadores en serie en la relación entre el apoyo familiar y la satisfacción con la vida, en este grupo de trabajadores. Conclusiónes: Los resultados sugieren que variables asociadas a la familia y a aspectos sociales de la alimentación influyen positivamente en la satisfacción vital de los trabajadores.

Clinical risk prediction model for 30-day all-cause re-hospitalisation or mortality in patients hospitalised with heart failure

BACKGROUND

This study aimed to develop a risk prediction model (AUS-HF model) for 30-day all-cause re-hospitalisation or death among patients admitted with acute heart failure (HF) to inform follow-up after hospitalisation. The model uses routinely collected measures at point of care.

METHODS

We analyzed pooled individual-level data from two cohort studies on acute HF patients followed for 30-days after discharge in 17 hospitals in Victoria, Australia (2014-2017). A set of 58 candidate predictors, commonly recorded in electronic medical records (EMR) including demographic, medical and social measures were considered. We used backward stepwise selection and LASSO for model development, bootstrap for internal validation, C-statistic for discrimination, and calibration slopes and plots for model calibration.

RESULTS

The analysis included 1380 patients, 42.1% female, median age 78.7 years (interquartile range = 16.2), 60.0% experienced previous hospitalisation for HF and 333 (24.1%) were re-hospitalised or died within 30 days post-discharge. The final risk model included 10 variables (admission: eGFR, and prescription of anticoagulants and thiazide diuretics; discharge: length of stay>3 days, systolic BP, heart rate, sodium level (<135 mmol/L), >10 prescribed medications, prescription of angiotensin converting enzyme inhibitors or angiotensin receptor blockers, and anticoagulants prescription. The discrimination of the model was moderate (C-statistic = 0.684, 95%CI 0.653, 0.716; optimism estimate = 0.062) with good calibration.

CONCLUSIONS

The AUS-HF model incorporating routinely collected point-of-care data from EMRs enables real-time risk estimation and can be easily implemented by clinicians. It can predict with moderate accuracy risk of 30-day hospitalisation or mortality and inform decisions around the intensity of follow-up after hospital discharge.

Relationships Between Work-to-Family Conflict and the Food Domain for Dual-Earner Parents With Adolescent Children

The impact of work-to-family conflict (WtoFC) can extend beyond family and work, and to other domains that contribute to well-being, such as the food domain. This study examined associations between WtoFC, perception of atmosphere of family meals (AFM), and satisfaction with food-related life (SWFoL) in dual-earner parents with adolescent children, and tested the mediating role of AFM between WtoFC and SWFoL. Questionnaires were administered to 473 different-sex dual-earner parents and one of their adolescent children (mean age 12.5 years, 51.4% male) in Temuco, Chile. Parents responded to a measure of work-to-family conflict; the three family members answered the Project-EAT Atmosphere of family meals scale, and the Satisfaction with Food-related Life Scale. Analyses were conducted using the Actor-Partner Interdependence Model and structural equation modeling. Results showed a negative association from WtoFC to SWFoL in both parents, while a more positive perception of atmosphere of family meals was linked to higher SWFoL in the three family members. Moreover, WtoFC was negatively linked to SWFoL in parents, while only mothers' WtoFC had a negative association with their adolescent children's SWFoL. Policymakers and organizations can contribute to workers' and their families' food-related well-being by fostering policies and measures to reduce WtoFC.

Diet quality during the COVID-19 pandemic: Effects of workplace support for families and work-to-family enrichment in dual-earner parents with adolescent children

Organizational support goes beyond the work domain, supporting workers' family role and thus generating resources that lead to work-to-family enrichment. Workers may invest these resources in improving their, and their family's, diet quality. However, data on the link between work resources, enrichment and diet quality during the COVID-19 pandemic is still emerging. The present study contributes to this literature by exploring the actor and partner effects between perceived workplace support for families, work-to-family enrichment, and diet quality in different-sex dual-earner parents with adolescent children; the potential mediating role of work-to-family enrichment between perceived workplace support for families and diet quality was also explored. A sample of 430 different-sex dual-earner parents and one of their adolescent children (mean age 13.0 years, 53.7% female) were recruited in Rancagua, Chile, during March and June 2020. Mothers and fathers responded to a measure of work-to-family enrichment, and a measure of Perceived Workplace Support for Families. The three family members answered the Adapted Healthy Eating Index. Analyses were conducted using the Actor-Partner Interdependence Model and structural equation modelling. Results showed that fathers' perceived workplace support for families positively and directly affected their own diet quality (actor effect) as well as the mothers' diet quality (partner effect), while indirectly positively affected the adolescents' diet quality via work-to-family enrichment (partner effect). Mothers' perceived workplace support for families enhanced their own work-to-family enrichment, which in turn improved their diet quality (actor effects). These results suggest that resources that both parents acquire through family-friendly workplace policies have positive effects on the three family members' diet quality by different mechanisms. Policymakers and organizations must aim to promote family-friendly workplace policies, particularly during ongoing crisis such as a pandemic.

Typologies of dual-earner households with adolescent children according to their satisfaction with food-related life

Introduction/aim: The aim of this study was to identify family profiles based on the level of satisfaction with food-related life of three family members (mother, father and one adolescent), and to assess if these profiles differ according to the perceived family functioning of all three family members, the work-life balance and mental health of the parents, and the sociodemographic characteristics. Method: The sample was composed of 269 dual-earner parents with one child between 10 and 17 years of age in Temuco, Chile. Results: A cluster analysis was used to distinguish three family profiles: “mothers moderately satisfied with their food-related life, and fathers and adolescents satisfied” (Group 1, 32.7%), “families extremely satisfied with their food-related life” (Group 2, 55.0%) and “mothers and fathers satisfied with their food-related life, and adolescents moderately satisfied” (Group 3, 12.3%). Groups differed in the way that the three family members’ perceived family functioning, both parents’ work-life balance and perception of the financial situation of the household, as well as in the mother’s depression, anxiety, and stress levels. Conclusions: The results of this study can guide research on the links between food-related life and other life domains, and it may provide guidelines for campaigns and interventions to promote healthy eating habits and practices in different age groups.

Improving Health Outcomes for People With Cancer in Rural and Regional Areas by Embedding Evidence-Based Smoking-Cessation Strategies Into Usual Care: A Study Protocol

Background: Smoking following a diagnosis of cancer is a powerful clinical risk indicator, with known poorer health outcomes and associated health care costs. In Australia, smoking rates are higher in rural and regional areas. There are established and effective interventions to promote smoking cessation after a diagnosis of cancer yet these are not in routine practice. Aim: This protocol paper reports on a study that aims to embed evidence-based smoking cessation strategies for people with cancer who are current smokers into routine care, resulting in in system wide improvements, an implemented program and model for further dissemination. Methods: Across three rural/regional sites, and with partners Quit Victoria and Western Alliance, this study employs a variety of methodologies to embed smoking cessation support to improve outcomes for people with cancer who currently smoke. Specifically, the project will embed a system of responsibilities and training in rural and regional health services to routinely engage people with cancer who smoke in support services. The program will: · Promote routine delivery of smoking cessation care by trained oncology staff (oncologists/nurses/ allied health) · Establish referral pathways to Quitline · Correspond with general practitioners, to: i) outline the benefits of quitting in this context, ii) promote access to nicotine replacement therapy and iii) support quitting in the community. · Improve routine recording of smoking status and documentation of provision of brief intervention (personalised advice given, resources provided) and outcomes. Participants: are oncology staff and general practitioners across three health services: Ballarat Health Service, East Grampians Health Service (Ararat), Wimmera Health Care Group (Horsham), all located in Victoria, Australia. Data collection will occur across four sources: 1) Oncology staff: qualitative and quantitative data collection understanding confidence and views on provision on cessation advice; 2) Monitoring Quitline calls, 3) Interview with local general practitioners and 4) Medical record reviews to explore frequency of recording of smoking status. Data will be collected pre/postintervention. Results: The project is underway with the intervention manuals in development. The project is due for completion in 2020. Conclusion: This project takes a health services approach to integration of smoking cessation support in routine care for people with cancer in rural and regional areas. This program of work has capacity to determine best approaches to integrate smoking cessation into routine care, resulting in reduced mortality and morbidity, improved effectiveness of anticancer treatments, and reduced health care costs; by establishing internationally relevant, embedded health care interventions.

Testing the Abbreviated Food Technology Neophobia Scale and its relation to satisfaction with food-related life in university students

The aims of this study were to test the relationships between food neophobia, satisfaction with food-related life and food technology neophobia, distinguishing consumer segments according to these variables and characterizing them according to willingness to purchase food produced with novel technologies. A survey was conducted with 372 university students (mean aged=20.4years, SD=2.4). The questionnaire included the Abbreviated version of the Food Technology Neophobia Scale (AFTNS), Satisfaction with Life Scale (SWLS), and a 6-item version of the Food Neophobia Scale (FNS). Using confirmatory factor analysis, it was confirmed that SWFL correlated inversely with FNS, whereas FNS correlated inversely with AFTNS. No relationship was found between SWFL and AFTNS. Two main segments were identified using cluster analysis; these segments differed according to gender and family size. Group 1 (57.8%) possessed higher AFTNS and FNS scores than Group 2 (28.5%). However, these groups did not differ in their SWFL scores. Group 1 was less willing to purchase foods produced with new technologies than Group 2. The AFTNS and the 6-item version of the FNS are suitable instruments to measure acceptance of foods produced using new technologies in South American developing countries. The AFTNS constitutes a parsimonious alternative for the international study of food technology neophobia.

Longitudinal multigroup invariance analysis of the satisfaction with food-related life scale in university students

This study examined longitudinal measurement invariance in the Satisfaction with Food-related Life (SWFL) scale using follow-up data from university students. We examined this measure of the SWFL in different groups of students, separated by various characteristics. Through non-probabilistic longitudinal sampling, 114 university students (65.8% female, mean age: 22.5) completed the SWFL questionnaire three times, over intervals of approximately one year. Confirmatory factor analysis was used to examine longitudinal measurement invariance. Two types of analysis were conducted: first, a longitudinal invariance by time, and second, a multigroup longitudinal invariance by sex, age, socio-economic status and place of residence during the study period. Results showed that the 3-item version of the SWFL exhibited strong longitudinal invariance (equal factor loadings and equal indicator intercepts). Longitudinal multigroup invariance analysis also showed that the 3-item version of the SWFL displays strong invariance by socio-economic status and place of residence during the study period over time. Nevertheless, it was only possible to demonstrate equivalence of the longitudinal factor structure among students of both sexes, and among those older and younger than 22 years. Generally, these findings suggest that the SWFL scale has satisfactory psychometric properties for longitudinal measurement invariance in university students with similar characteristics as the students that participated in this research. It is also possible to suggest that satisfaction with food-related life is associated with sex and age.

Food neophobia, life satisfaction and family eating habits in university students

Abstract: The aim of this study was to categorize university students based on their association between food neophobia and levels of subjective well-being, in general and in the food domain, and their perception of their family's eating habits. A survey was conducted among 372 university students from southern Chile. The questionnaire included the Food Neophobia Scale (FNS), Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life (SWFL), Health-related Quality of Life Index (HRQOL-4), and Family Eating Habits Questionnaire (FEHQ). Three student types were distinguished by cluster analysis: Group 1 (26.9%) had the highest scores on the FNS, SWLS and SWFL. Group 2 (40.8%) had a high score on the FNS but the lowest scores on the SWLS and SWFL. Group 3 (32.3%) had the lowest FNS score and high scores on the SWLS and SWFL. Group 2 stood out in having a low score on the FEHQ's component for cohesiveness of family eating. These results suggest that both neophobic and non-neophobic students have positive levels of satisfaction with life and food-related life, and that satisfaction among neophobic students is related to family eating patterns, especially cohesiveness in family eating.

Dietary restraint and self-discrepancy in male university students

Self-discrepancy describes the distance between an ideal and the actual self. Research suggests that self-discrepancy and dietary restraint are related, causing a significant impact on the person's well-being. However, this relationship has been mostly reported in female and mixed populations. In order to further explore dietary behaviors and their relations to self-discrepancy and well-being-related variables in men, a survey was applied to a non-probabilistic sample of 119 male students from five Chilean state universities (mean age=21.8, SD=2.75). The questionnaire included the Revised Restraint Scale (RRS) with the subscales weight fluctuations (WF) and diet concern (DC), the Satisfaction with Life Scale (SWLS), the Satisfaction with Food-Related Life Scale (SWFL), the Nutrition Interest Scale (NIS), and the Self-discrepancy Index (SDI). Questions were asked about socio-demographic characteristics, eating and drinking habits, and approximate weight and height. A cluster analysis applied to the Z-scores of the RRS classified the following typologies: Group 1 (22.7%), men concerned about weight fluctuations; Group 2 (37.0%), men concerned about diet and weight fluctuations; Group 3 (40.3%), unconcerned about diet and weight fluctuations. The typologies differed in their SDI score, restriction on pastry consumption and reported body mass index (BMI). Students with higher DC and WF scores had a higher BMI, and tended to report high self-discrepancy not only on a physical level, but also on social, emotional, economic and personal levels. This study contributes to the literature on subjective well-being, dietary restraint and self-discrepancy in men from non-clinical samples.

Relationship between the domains of the Multidimensional Students' Life Satisfaction Scale, satisfaction with food-related life and happiness in university students

AIM

To characterize types of university students based on satisfaction with life domains that affect eating habits, satisfaction with food-related life and subjective happiness.

MATERIALS AND METHODS

A questionnaire was applied to a nonrandom sample of 305 students of both genders in five universities in Chile. The questionnaire included the abbreviated Multidimensional Student's Life Satisfaction Scale (MSLSS), Satisfaction with Food-related Life Scale (SWFL) and the Subjective Happiness Scale (SHS). Eating habits, frequency of food consumption in and outside the place of residence, approximate height and weight and sociodemographic variables were measured.

RESULTS

Using factor analysis, the five-domain structure of the MSLSS was confirmed with 26 of the 30 items of the abbreviated version: Family, Friends, Self, Environment and University. Using cluster analysis four types of students were distinguished that differ significantly in the MSLSS global and domain scores, SWFL and SHS scores, gender, ownership of a food allowance card funded by the Chilean government, importance attributed to food for well-being and socioeconomic status.

CONCLUSIONS

Higher levels of life satisfaction and happiness are associated with greater satisfaction with food-related life. Other major life domains that affect students' subjective well-being are Family, Friends, University and Self. Greater satisfaction in some domains may counterbalance the lower satisfaction in others.

Eating habits and subjective well-being. A typology of students in Chilean state universities

The purpose of this study was to distinguish and characterize university student typologies according to their life satisfaction and satisfaction with their food-related life. An online survey was applied between June and August 2013 in five state universities in Chile, to 369 university students (mean age = 20.9 years, SD = 2.27). The survey included the Health-related Quality of Life Index-4 (HRQOL), Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life Scale (SWFL), as well as questions about the place of residence, importance of food for well-being, frequency of meals in the place of residence and the frequency of consumption of eight food groups. A cluster analysis was used to determine student typologies. Three typologies of students were distinguished with significant differences in the average scores of the SWLS and SWFL scales, self-perception of health, days with mental health problems, number of days of health-related incapacity, place of residence, socioeconomic status, importance of food for well-being, frequency of breakfast and dinner in the place of residence, frequency of consumption of meat, milk, fruits and vegetables. It was found that most students with higher levels of life satisfaction and satisfaction with food-related life live with their parents, eat at home more frequently, report fewer health problems, have healthful eating habits and consider food very important for their well-being. Although it is necessary to promote or improve the campaigns that foster healthful eating in the entire university population, these campaigns must be specifically targeted to students who do not receive direct support from their families.

Dietary restraint and subjective well-being in university students in Chile

OBJECTIVE

To characterize university students typologies according to chronic food restriction, satisfaction with life and food consumption.

MATERIALS AND METHOD

A questionnaire was applied on a non-probability sample of 369 male and female students from five Chilean universities. The questionnaire included: Revised Restraint Scale (RRS), Satisfaction with Life Scale (SWLS), Satisfaction with Food-related Life (SWFL) and the Health-related Quality of Life Index. The survey included food and drink consumption habits, weight and approximate height and sociodemographic variables.

RESULTS

Two factors in the RRS were detected by exploratory factor analysis: Preoccupation with Diet (PD) and Weight fluctuations (WF). A confirmatory factor analysis validated the bifactor structure of the RRS with an acceptable adjustment kindness. The cluster analysis allowed a distinction of four typologies with a significant variation in PD, WF, SWLS and SWFL scoring, number of days with mental health problems, frequency of alcoholic drinks consumption, restraint on the consumption of certain foods, drinks and spices, consumption frequency of fruit out of the main meals and types. Typologies did not differ on their body mass index.

CONCLUSIONS

Both, students preoccupied with diet and those who are not, experience higher levels of satisfaction with life and with food. Lower levels of global life satisfaction and satisfaction with food are related with the fluctuations in weight.

[Eating habits and subjective well-being among university students in southern Chile]

AIM

To distinguish typologies of university students in southern Chile on the basis of their level of satisfaction with life and food-related life, and to characterize them according to their eating habits inside and outside the place of residence, aspects associated with health and demographic characteristics.

MATERIALS AND METHODS

A structured questionnaire was applied to a non-probabilistic sample of 347 students at the Universidad de La Frontera, Temuco, Chile. The instruments for collecting information included the SWLS (Satisfaction with Life Scale), SWFL (Satisfaction with Food-related Life) and the HRQOL (Health-related Quality of Life Index). Questions were asked about eating habits inside and outside the place of residence, weight and approximate height, and variables for demographic classification.

RESULTS

Using a cluster analysis, three student typologies were distinguished, with significant differences in the SWLS and SWFL scores. The typologies differed in the number of days affected by emotional health problems, classification of their nutritional status (BMI), self-perception of their state of health, importance of food to personal well-being, place of residence during the period of studies, frequency of eating in the place of residence and frequency of meals at inconvenient times.

CONCLUSIONS

The possibility of living with parents during the period of university studies is associated with better eating habits, better emotional health and self-perception of health, lower prevalence of overweight and obesity, and greater satisfaction with the life and food-related life.

¿Izquierda o derecha? El desarrollo de las relaciones espaciales proyectivas en escolares mapuche y no mapuche

La presente investigación tuvo como propósito determinar las diferencias en el desarrollo de la identificación izquierda-derecha en escolares mapuche y no mapuche de procedencia urbana y rural. Participaron de este estudio un total de 210 niños escolarizados en escuelas con altos índices de vulnerabilidad social de las regiones chilenas del Bío Bío y La Araucanía, distribuidos en 152 escolares de procedencia rural y 54 de procedencia urbana, cuyas edades oscilaron entre los 6 y los 12 años de edad. Todos los participantes respondieron a una tarea que evaluaba la identificación de izquierda-derecha homolateral, izquierda-derecha contralateral y las relaciones relativas izquierda-derecha entre tres objetos. Los resultados no mostraron diferencias estadísticamente significativas entre los niños mapuche y no mapuche, pues en ambos grupos -especialmente en los escolares del sector rural- el desempeño en la identificación izquierda-derecha estuvo por debajo de las edades de logro descritas para poblaciones occidentales. La identificación de las relaciones relativas entre tres objetos se observó en una cantidad ínfima de niños. Se discuten las implicaciones teóricas y educativas de los resultados obtenidos, teniendo en cuenta la relevancia del conocimiento espacial para el aprendizaje de conceptos fundamentales del curriculum escolar.

Applications of redundancy analysis for the detection of chemical response patterns to air pollution in lichen

The lichens Ramalina celastri (Spreng.) Krog & Swinsc., Punctelia microsticta (Müll. Arg.) Krog and Canomaculina pilosa (Stizenb.) Elix & Hale were transplanted simultaneously to 17 urban-industrial sites in a northwestern area of Córdoba city, Argentina. The transplantation sites were set according to different environmental conditions: traffic, industries, tree cover, building height, topographic level, position in the block and distances from the river and from the power plant. Three months later, chlorophyll a, chlorophyll b, phaeophytin a, soluble proteins, hydroperoxy conjugated dienes, malondialdehyde concentration and sulfur accumulation were determined, and a pollution index was calculated for each sampling site. Redundancy analysis was applied to detect the variation pattern of the lichen variables that can be 'best' explained by the environmental variables considered. The present study provides information about both the specific pattern response of each species to atmospheric pollution, and environmental conditions that determine it. As regards pollutants emission sources R. celastri showed a chemical response associated mainly with pollutant released by the power plant and traffic. P. microsticta and C. pilosa responded mainly to industrial sources. Regarding environmental conditions that affect the spreading of air pollutants and their incidence on the bioindicator, the topographic level and tree cover surrounding the sampling site were found to be important for R. celastri, tree cover surrounding the sampling site and the building height affected P. microsticta, while building height did so for C. pilosa.

Atmospheric quality and distribution of heavy metals in Argentina employing Tillandsia capillaris as a biomonitor

The atmospheric quality and distribution of heavy metals were evaluated throughout a wide region of Argentina. In addition, the biomonitor performance of Tillandsia capillaris Ruiz & Pav. f. capillaris was studied in relation to the accumulation of heavy metals and to its physiologic response to air pollutants. A sampling area of 50,000 km2 was selected in the central region of the Argentine Republic. This area was subdivided into grids of 25 x 25 km. Pools of T. capillaris, where present, were collected at each intersection point. From each pool three sub-samples were analyzed independently. Furthermore, five replicates were collected at 20% of the points in order to analyze the variability within the site. The content of Co, Cu, Fe, Ni, Mn, Pb and Zn was determined by Atomic Absorption Spectrometry. Chemical-physiological parameters were also determined to detect symptoms of foliar damage. Chlorophylls, phaeophytins, hydroperoxy conjugated dienes, malondialdehyde and sulfur were quantified in T. capillaris. Some of these parameters were used to calculate a foliar damage index. Data sets were evaluated by one-way ANOVA, correlation analysis, principal component analysis and mapping. Geographical distribution patterns were obtained for the different metals reflecting the contribution of natural and anthropogenic emission sources. According to our results it can be inferred that Fe, Mn and Co probably originated in the soil. For Pb, the highest values were found in the mountainous area, which can be attributed to the presence of Pb in the granitic rocks. Ni showed mainly an anthropogenic origin, with higher values found in places next to industrial centers. For Zn the highest values were in areas of agricultural development. The same was observed for Cu, whose presence could be related to the employment of pesticides. The foliar damage index distribution map showed that the central and southeastern zones were the ones where the major damage in the bioindicator was found. The central zone coincides with the city of Córdoba whereas the southeastern area is strictly agricultural, so the high values found there could be related to the use of pesticides.

Relationship between foliar chemical parameters measured in Melia azedarach L. and environmental conditions in urban areas

A diagnostic study was done on Melia azedarach L. in relation to atmospheric pollutants in Córdoba city, Argentina. The study area receives regional pollutants, and it was categorized taking into account traffic level, industrial level, location of the sample point in relation to the corner, treeless condition, building type, topographic level and distance to the river. Water content and Specific Leaf Area (SLA) were calculated; and concentrations of soluble proteins, sulphur, hydroperoxy conjugated dienes (HPCD), chlorophylls (Total Chl) and pheophytins (Total Paeoph) were determined in leaf samples. HPCD correlated positively with industry, topographic level and distance to the river, and with a combination of the environmental variables (ECI); pigments correlated negatively with traffic level and with ECI; Total Phaeoph/Total Chl ratio correlated positively with traffic, building and ECI. On the basis of our results, traffic level, industrial level, building type, topographic level and distance to the river are the environmental variables to bear in mind when selecting analogous sampling points in a passive monitoring program. An approximation to predict tree injury may be obtained by measuring water content, soluble proteins, sulphur, HPCD and pigments as they are responsible for the major variability of data. This study revealed that M. azedarach was sensitive to air pollutants from traffic and industry. Thus, in those sampling sites with the maximum score for traffic level, industrial level and ECI, the highest values of the parameters that indicate foliar damage together with the least pigment concentration were observed.

[Decompensated diabetes mellitus and hyperchloremic metabolic acidosis: a case with both pathologies]

Diabetic ketoacidosis is manifested by elevated blood glucose levels, ketosis and metabolic acidosis with increased anion gap. A transitory hyperchloremic acidosis, with normal anion gap, can appear. We report a 21 years old female with a type 2 diabetes mellitus, admitted to the emergency room of a general hospital with hyperglycemia, absence of ketonemia, severe hypokalemia and hyperchloremic metabolic acidosis. Initially, she was diagnosed and treated as a severe diabetic ketoacidosis. Normal blood glucose levels were rapidly achieved but electrolyte and acid base alterations persisted, leading to the suspicion that another associated condition was causing the acidosis and hypokalemia. Urinary pH and anion gap measurement, the study of renal acidification and a bicarbonate overload test lead to the diagnosis of a distal renal tubular acidosis, secondary to a Sjögren syndrome, that was confirmed with a Schirmer test and positive anti Ro antibodies. In this diabetic patient, the acute hyperglycemia intensified the hypokalemia of her distal renal tubular acidosis and unchained the acute metabolic condition.

Exploring Chemical Variables in Ligustrum lucidum Ait. F. Tricolor (Rehd.) Rehd. in Relation to Air Pollutants and Environmental Conditions

/ A diagnostic study was done on Ligustrum lucidum Ait. f. tricolor (Rehd.) Rehd. in relation to atmospheric pollutants in Cordoba city, Argentina. The study area receives regional pollutants and was categorized taking into account traffic level, industrial density, type of industry, location of the sample point in relation to the street corner, treeless condition, and topographic level. Dried weight/fresh weight ratio (DW/FW) and specific leaf area (SLA) were calculated, and concentrations of chlorophylls, carotenoids, total sulfur, soluble proteins, malondialdehyde (MDA), and hydroperoxy conjugated dienes (HPCD) were determined in leaf samples. Sulfur content correlates positively with traffic density and SLA correlates negatively with some combinations of the categorical variables; MDA correlates positively with topographic level and total protein concentration correlates negatively with treeless condition. On the basis of our results, traffic, location of trees, type of industry, situation of a tree with respect to others, and topographic level are the environmental variables to bear in mind when selecting analogous sampling points in a passive monitoring program. An approximation to predict tree injury may be obtained by measuring DW/FW ratio, proteins, pigments, HPCD, and MDA as they are responsible for the major variability of data.KEY WORDS: L. lucidum Ait. f. tricolor (Rehd.)

Heart rate variability and inappropriate sinus tachycardia after catheter ablation of supraventricular tachycardia

Sinus tachycardia has been reported after radiofrequency catheter ablation of supraventricular tachycardia. Frequently, these patients require beta-blocking agents for symptomatic control. The purpose of this study was to evaluate prospectively the incidence of inappropriate sinus tachycardia and heart rate variability after ablation of atrioventricular nodal reentrant tachycardia and accessory pathways. Patients undergoing ablation had 24-h ambulatory monitoring ECG (Holter) performed before the procedure, on the day of the ablation, and 3 months afterwards. There were 170 patients, mean age 48 +/- 23 years; 93 were female. A complete study of the 24-h Holter with analysis of heart rate variability: SD, rMSSD, pNN50, high and low frequency was obtained. There was a low prevalence of inappropriate sinus tachycardia after the ablation procedure (10 of 170 patients: five with four atrioventricular nodal reentry, with posteroseptal accessory pathways and one of the latter following ablation of the left accessory pathway). There was no modification of time and frequency domain parameters of heart rate variability in the remaining patients who underwent radiofrequency ablation. Holter monitoring 3 months after ablation showed that parameters of heart rate and heart rate variability had normalized in patients who had developed inappropriate sinus tachycardia. Inappropriate sinus tachycardia may be initiated by both radiofrequency ablation of atrioventricular nodal reentrant tachycardia and radiofrequency ablation of posteroseptal accessory pathways. Specific damage to the posteroseptal region is responsible for these changes, which usually recover spontaneously after 3 months.

[Prevalence of thinness and excessive fatness in a group of school children of the city of Cordoba, Argentina]

Findings of a nutritional evaluation study, using triceps skinfold, are reported. The study was carried out in 1,615 school-children from 5 to 12 years, pertaining to the low socioeconomic status of the city of Córdoba, Argentina. Measurements were done during the years 1983 and 1984 by Center's examiners with a Lange caliper, according to international anthropometric methodology. Interintra observer technical error was found to be within tolerance limits reported by other authors. Local standards were used to determine the prevalence of thinness and excessive fatness, by comparing them to tricep skinfold of each child, and selecting those children where this parameter presented values less than or equal to 10th percentile and fatness greater than or equal to 90th percentile. Furthermore, comparison between median triceps skinfold of the examined group, the local standards and Frisancho's norms for US population was also made. Results revealed that: a) the prevalence of thinness (19.9%) was almost twice the percentage expected for a normal population; in contrast, occurrence of excessive fatness (6.4%) was found to be below the expected value; b) prevalence of thinness was not statistically associated to age nor sex; c) frequency of excessive fatness was significantly higher in the 8-11 year-old male group (8, 9%, p much less than 0.0005) and in the girls group (10.8%), P much less than 0.005) the prevalence of fatness in girls increased with age, and figures revealed that from eight years onwards this exceeded the expected percentage, and d) median triceps skinfold of the group under study was generally below local and foreign norms. It is concluded that potential or real nutrition problems as those mentioned above, may be grossly identified using the triceps skinfold as the single anthropometric indicator.
