RESUMEN

AIM: Anorectal malformations (ARMs) are rare congenital colorectal anomalies with long lasting consequences, among which faecal incontinence is one of the most relevant since it may strongly affect patients' health-related quality of life (HRQoL). Although a growing body of literature supports the importance of self-efficacy in chronic disease health outcomes, only few studies have focused on self-efficacy in ARMs and in faecal incontinence. The purpose of the present study is to examine the mediational role of self-efficacy in the path between faecal incontinence and HRQoL in patients born with ARMs. METHOD: Ninety-eight adult patients from the Italian Association for Anorectal Malformations (AIMAR) responded to measures of faecal incontinence, self-efficacy for managing ARM consequences, and physical and mental HRQoL (SF-36). Data were analysed by means of structural equation models. RESULTS: The tested model provides support for the guiding hypothesis. Fit indices indicate that the model fits the data well (χ2  = 33.48, df = 23, P = 0.07; comparative fit index [CFI] = 0.97; root mean square error of approximation [RMSEA] = 0.07; standardized root mean square residual [SRMR] = 0.05). Faecal incontinence has negative effects on both physical and mental HRQoL, as well on self-efficacy. In turn, self-efficacy has a positive and direct effect on mental HRQoL. CONCLUSION: Faecal incontinence is the most relevant and negative factor influencing HRQoL; in addition, self-efficacy contributes in reducing emotional distress and in improving mental health outcomes. Longitudinal and controlled studies may be helpful to evaluate the effectiveness of self-efficacy interventions in improving mental HRQoL in patients with faecal incontinence.

RESUMEN

Childhood overweight and obesity in both girls and boys is reaching epidemic proportions over the world, Italy included. Childhood obesity has been linked to deleterious health consequences. There is a need to develop theory based and cost-effective interventions to promote healthy eating and physical activity with the aim to reduce obesity. The purpose of this study was to evaluate a long-term theory-based intervention to promote healthy lifestyles in underserved school-aged children. A quasi experimental design was adopted, in order to evaluate the effectiveness of the intervention, considering information from their parents. Parents were asked to rate their children attitude, motivation and behaviour regarding two energy balance-related behaviours. Results indicate that pupils involved in the intervention were more likely to do physical activity in leisure time and have more positive attitudes toward exercise compared to the control group. About eating habits, children involved in the intervention were more likely to choose healthy foods and less likely to choose fat foods compare to the control group. Changes in attitude and motivation between the baseline and the follow up and the two groups are also shown, even if not significant. Despite several limitations in the design, this study provided further support to the argument that Self-determination theory-based interventions could result in meaningful health-behavior changes (AU)


Niñez sobrepeso y obesidad en niños y niñas está alcanzando proporciones epidémicas en el mundo entero, Italia incluida. La obesidad infantil se ha relacionado con consecuencias perjudiciales para la salud. Hay una necesidad de desarrollar intervenciones teoría basada y rentables para promover la alimentación saludable y la actividad física con el objetivo de reducir la obesidad. El propósito de este estudio fue evaluar una intervención basada en la teoría de largo plazo para promover estilos de vida saludables en niños en edad escolar de escasos recursos. Se adoptó un diseño cuasi experimental, con el fin de evaluar la eficacia de la intervención, teniendo en cuenta la información de sus padres. Se pide a los padres para evaluar a sus hijos la actitud, la motivación y el comportamiento con respecto a los comportamientos relacionados con saldo de dos energías. Los resultados indican que los alumnos que participan en la intervención tenían más probabilidades de hacer actividad física en el tiempo libre y tienen actitudes más positivas hacia el ejercicio en comparación con el grupo control. Acerca de los hábitos alimenticios, los niños que participaron en la intervención eran más propensos a elegir alimentos saludables y menos propensos a elegir alimentos ricos en grasas en comparación con el grupo control. Los cambios en la actitud y la motivación entre el inicio y el seguimiento y los dos grupos se muestran también, aunque no significativamente. A pesar de varias limitaciones en el diseño, este estudio proporcionan más apoyo al argumento de que las intervenciones basadas en teoría de la autodeterminación podrían resultar en cambios significativos que afectan a su salud significativamente (AU)

RESUMEN

PURPOSE: Coping strategies have been acknowledged as crucial for the well-being and for health-related quality of life (HRQoL). The main aim of the present study is to determine whether different types of coping strategies predict HRQoL in patients born with ARM, above and beyond the variance explained by fecal and urinary continence. METHODS: 71 adult patients from the Italian Parents' and Patients' Organization for Anorectal Malformations (AIMAR) participated in the study. Participants completed measures of fecal and urinary continence of the Hirschsprung Disease/Anorectal Malformation Quality of Life (HAQL) (Hanneman et al. in Dis Col Rect 44:1650-1660, 2001), the Short Form Health Survey (SF-36) (Apolone and Mosconi in J Clin Epidemiol 51:1025-1036, 1998), and the Brief Coping Orientation to Problems Experienced (COPE) Inventory (Carver in Int J Behav Med 4:92-100, 1997), which measures different coping strategies: maladaptive, problem-focused and emotion-focused. RESULTS: Hierarchical regression analyses showed that fecal continence (ß = 0.53, p < 0.01) and urinary continence significantly predict (ß = 0.23, p < 0.05) Physical HRQoL. Fecal continence (ß = 0.36, p < 0.01) and maladaptive coping strategies significantly predict (ß = -0.27, p < 0.05) Mental HRQoL. CONCLUSION: Besides considering the importance of fecal and urinary continence for Physical HRQoL, these findings indicate that maladaptive coping strategies are associated with worse Mental HRQoL. Interventions aimed at enhancing the patients' HRQoL should target coping strategies by reducing denial, behavioral disengagement, substance abuse, and self-blame.

RESUMEN

A prospective field study conducted with runners training for an upcoming marathon (Marathon of Rome 2013) examined the relation between regulatory modes, locomotion and assessment, and stress. Integrating regulatory mode theory and the dualistic model of passion, we hypothesized that the relation between regulatory modes (evaluated 3 months before the race) and the experience of stress approaching the marathon, is mediated by the type of passion (harmonious vs obsessive) athletes experience with regard to marathoning. Results revealed that (a) locomotion positively predicted harmonious passion, which in turn reduced athletes' experience of stress; and (b) assessment positively predicted obsessive passion, which in turn enhanced athletes' experience of stress. Overall, the present results suggest that proximal psychological mechanisms such as basic regulatory mode orientations can predict distal outcomes such as stress indirectly through their relation with motivational phenomena such as passion.

RESUMEN

BACKGROUND/PURPOSE: Disease-specific quality of life (QoL) may be more or less relevant when children enter preadolescence/adolescence. Few attentions have been given to development and transition periods. Aim of the present longitudinal study is to evaluate ARM specific changes in QoL and the stability of QoL over 6 years. METHODS: Questionnaires were sent to families of the AIMAR Association (in 2007 and in 2013/2014). They included the Hirschsprung's Disease/ARM QoL Questionnaire (HAQL, [1]). Rank correlations and within group comparisons for the HAQL subscales were conducted analyzing the scores of time 1 vs time 2. Gender effects were tested. RESULTS: 134 parents answered the questionnaires at time 1 and 73 at time 2. Results of the repeated Analyses of Variance indicated improvements in the continence subscales ("Presence of Diarrhea," "Fecal Continence"). QoL significantly worsened in "Social and Emotional Functioning" and in "Body Image" areas. The analysis of stability of change indicates that QoL scores remain stable, with the exception of the Body Image area. CONCLUSIONS: Despite improvements in the continence areas, parents reported worse levels of QoL in the psychosocial areas, as their child grow. As patients grow, they might have more difficulties in daily and social activities, and feel more frequently ashamed and more dissatisfied with their body.

RESUMEN

There is growing evidence suggesting that nutritional supplement (NS) use is strongly associated to doping use in elite and amateur sports. However, there is a paucity of research on the psychological processes that underlie this association. The present study investigated the cognitive and behavioral components of the association between NS use and doping among adolescent sub-elite athletes. Six hundred and fifty adolescent athletes completed a questionnaire including measures of doping intentions, attitudes, norms, and beliefs about NS use. The results showed that NS users who did not report doping use had significantly stronger doping intentions and more positive attitudes and favorable beliefs toward doping use, as compared with athletes who did not use NS. In support of the "shared mental representations" hypothesis, the present findings show that NS use is associated with biased reasoning patterns in favor of doping use. This mechanism may explain why some NS users decide to engage in doping.

RESUMEN

PURPOSE: Managing a chronic disease may be a difficult task which may lead patients to experience psychological distress and depression. Some studies showed that, in ARM patients, fecal incontinence (FI) is related to symptoms of depression while others studies did not. No studies investigated this relationship in adults. Since fear of having FI episodes, negative feelings associated with these episodes, and difficulties in close and sexual relationships are often reported by patients as important consequences of ARM, we were interested in investigating whether these aspects contribute in explaining feelings of depression. METHODS: Questionnaires were sent to 160 adult members of the Italian Association for Anorectal Malformation. A new scale measuring the fear of having FI episodes, negative feelings associated with these episodes and difficulties in close/sexual relationship was developed. Depressive feelings and FI were also measured. RESULTS: Seventy-two adults answered the questionnaires. Regression analyses showed that, in males, depressive feelings were predicted by difficulties in close and sexual relationships (B = 0.46; P < 0.01), while, in females, they were predicted by the fear of having FI episodes (B = 0.53; P < 0.05) and by negative feelings (B = 0.58; P < 0.01). CONCLUSIONS: Interventions aimed to prevent depression in ARM patients should consider gender and should be targeted on different aspects.

RESUMEN

PURPOSE: Quality of life (QOL) is an important endpoint in health outcomes research, especially in pediatric chronic conditions. While some studies suggest that patients with ARM report a lower level of physical and psychosocial QOL, as compared to healthy peers, not all research shows this consistently. The aim of this study was to compare the QOL of Italian children and adolescents with ARM to the QOL of a large control sample of healthy peers. METHODS: Parents of 109 children with ARM and 336 schoolchildren, completed the Pediatric Quality of Life Inventory. Analysis of variances were used to compare the groups. RESULTS: Compared to healthy peers, children with ARM showed lower emotional functioning (F = 8,41; p = .004), social functioning (F = 4,9; p = .027) and school functioning (F = 14,7; p = .000). In the adolescent group, females had a worse QOL in the physical functioning domain (F = 5,01; p = .03) than males, independent of group membership. CONCLUSIONS: While children with ARM show a more impaired QOL compared to their peers, this difference does not emerge in the adolescent group. Our results are consistent with previous findings which hypothesize that while patients with ARM face more difficulties during childhood, by adolescence they may have learned to overcome these difficulties.

RESUMEN

PURPOSE: Fecal incontinence is a common problem in children and adolescents with anorectal malformation (ARM) and may negatively impact psycho-social well-being. Mothers' perception of social support has been proved to contribute to children's quality of life (QOL). Considering ARM studies, the role of family and social resources have received little attention. The aim of the present study was to analyze whether mothers' perception of social support mediates the impact of child fecal incontinence on his/her QOL. METHODS: One hundred and nine mothers with a child born with ARM (aged 6-15 years old; mean age = 11 years) completed questionnaires including the fecal incontinence subscale of the Hirschsprung's Disease/Anorectal Malformation QOL Questionnaire, the Pediatric QOL Inventory, and a social relationship questionnaire. Structural equation models were used to explore the relations hypothesized. RESULTS: No differences were found in the QOL scores across gender. The hypothesized model fits the data well; mothers' perception of social support partially mediated the relationship between fecal incontinence and QOL. CONCLUSIONS: An important direction for pediatric surgeons and their interdisciplinary teams may be to develop strategies to strengthen mothers' social relationships.

RESUMEN

Empirical evidence indicates that the dissatisfaction with one's body is widely present in the general population even at very early ages, and that it is predictive of future eating disorders. The family seem particularly influent for the development of body dissatisfaction while sports practice is associated to a higher prevalence of disordered eating. However the role of sports practice in the development of body dissatisfaction is still under debate and only few studies have evaluated together the influences of family and sport practice on body dissatisfaction. The present study aimed at evaluating both the singular and conjoint role of the type of sport and maternal influences in young female children. The sport influence was assessed comparing aesthetic and non-aesthetic disciplines; the mother's influence was evaluated considering her personal characteristics and her desire to have a thinner child. Results evidence that children involved in aesthetic sports, although thinner than those involved in non-aesthetic sports, report higher desire to be much thinner and have mothers who pressure them toward a greater thinness. Furthermore, children's body dissatisfaction in the sport groups is predicted by maternal characteristic like her habit to restrict her own eating and her perfectionism.

RESUMEN

BACKGROUND: Sleep disorders are very frequent in hemodialyzed patients, but the relationship between these disorders and water withdrawal, urea removal and comorbidities has not been sufficiently clarified. METHODS: The study comprised a group of 88 patients in good nutritional condition, with target hemoglobin concentration, good control of blood pressure and optimal dry weight. After answering a questionnaire (SDQ) based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) patients were assigned to one of 3 groups: those with no disturbances (no.20), those with subclinical disorders (n.35) and insomniacs (n.33). Yearly fluid and urea withdrawal by dialysis and the Charlson Comorbity Index were measured. RESULTS: Sleep disorders were observed in 77.27% of the patients. There was no difference in body fluid and urea withdrawal between groups. In the group of patients with no sleeping disturbances, the Charlson Comorbidity Index was significantly lower (p<0.001) than in patients with subclinical disorders or insomnia and emerged as a strongly associated with sleep disturbances. The study also attributes a predictive role to age, dialytic age, dialysis shift, antihypertensive drugs. The data indicate that, in evaluating sleeping disorders in patients on maintenance hemodialysis, comorbidities should be assessed.

RESUMEN

Clinical interviews are considered the gold standard for the evaluation of the specific psychopathology associated with eating disorders. However, there are situations in which brief but valid and reliable self-report questionnaires can be helpful. For this reason, we have developed a new questionnaire, called the DEQ (Disordered Eating Questionnaire), brief enough to be used in epidemiological screenings, that evaluates the frequency and intensity of disordered eating attitudes and behaviours within a time frame of three months and addresses face valid questions to the general population. The aim of this study was to evaluate the dimensionality, reliability and convergent validity of this questionnaire. The DEQ was filled in by Italian secondary school girls and boys, together with the Contour Drawing Rating Scale (CDRS) and with the Eating Attitudes Test (EAT-26). The results showed a single component that explain a portion of variance of around 36%. The reliability of the scale is highly satisfactory. The scale is also valid, since scores on the DEQ scale are significantly and highly correlated with body dissatisfaction, measured by the CDRS, with body mass inex (BMI) and with all the subscales of the EAT-26. As expected, there were gender differences, given that DEQ scores were higher in females than in males.

RESUMEN

The SDQ is a brief self-report insomnia questionnaire, which permits the rapid evaluation of insomnia based on the DSM-IV and ICSD-R criteria. The SDQ was developed to provide a fast and valid instrument both for the pre-screening of subjects who complain of insomnia and for epidemiological studies based on standardized definitions of this sleep disorder. Two studies were carried out in order to assess the validity of the SDQ as a self-report measure of insomnia. In the first study the convergent validity of the SDQ was assessed with respect to the global score of the Pittsburgh Sleep Quality Index (PSQI) in a sample of general practitioners' patients. The second study assessed the sensitivity and the specificity of the SDQ in discriminating between insomniacs or normal sleepers in a sample of college students who were given an extensive sleep evaluation within an insomnia counseling program. The SDQ classifications have a good convergent validity with the global sleep quality scores of the PSQI and its classifications of students who complain of or who do not complain of problems of insomnia have a sensitivity of 95% and a specificity of 87%. Results indicate that the SDQ is a valid paper and pencil instrument to screen insomnia.

RESUMEN

INTRODUCTION: The Epworth sleepiness scale (ESS) is widely used as a way of measuring subjective sleep propensity in research and clinical practice. Psychometric studies do not rule out the presence of more than one latent dimension underlying the items. OBJECTIVE: Aims of the present study were to: (a) evaluate psychometric proprieties of the ESS by means of classic psychometric techniques; (b) compare them with those from a newly developed resistance to sleepiness scale (RSS); (c) evaluate, following the latent trait theory, whether the items of both ESS and RSS could be conceptualized as different levels of an interval variable representative of a single latent trait related to sleep propensity. METHODS: One hundred and forty-six inpatients suffering from different sleep disorders filled in both the RSS and ESS in a sleep disorder centre. RESULTS: Indexes of fit derived by the application of the extended logistic model are consistent with the idea that each ESS item can be conceptualized as different levels of an interval variable representative of a single latent trait. However, most of the ESS items are found to be located at the opposite extremes of this continuum. CONCLUSIONS: The under representation of situations characterized by an intermediate soporific nature in the ESS could limit ESS sensitivity to detect intermediate variations of sleep propensity.

RESUMEN

Night or shift work is to a relevant extent unavoidable, suits a growing preference for flexibility and is predicted to spread. However, a significant percentage of shift workers report discomfort or health problems and they often (15-20% of cases) move to different occupations. Apart from social implications, the issue has medical and scientific relevance, with evidence suggesting that the circadian rhythm phases are neither equivalent nor interchangeable with respect to function and performance. Shift work may affect the gastrointestinal and cardiovascular functions, alter the hormonal and sleepiness cycles, favor sleep disturbances of medical relevance, interfere with behavior and social life and increase the risk of accidents (e.g. road accidents). The implications for clinical (neuro)pharmacology are relevant and, in several instances, critical. Shift work can interfere with mechanisms regulating drug kinetics in peripheral compartments and action at selective brain sites, either directly or through effects on the gastrointestinal/hormonal cycles. In this paper, the relevant literature is reviewed and original data on the effects of shift work are reported. Basic and clinical research should take into account the possible effects on drug action of an active life and working schedule in inappropriate phases of the circadian cycles and the risk of inadequate drug dosing or unexpected abnormal action in subjects under long-term or chronic treatment. A scientific approach, action by the scientific community involved in pharmacological research and monitoring by the regulating agencies are advisable. Regulation may help reduce the medical and social impact and improve quality of life.

RESUMEN

A newly developed questionnaire was administered to 140 hemodialyzed patients (82 M and 58 F) who have achieved adequate anemia correction according to the best guidelines with the aim: to evaluate the prevalence of clinical/subclinical dyssomnias in these patients; to study the influence of the dialytic shift (morning versus afternoon schedules) on sleep duration and disturbancies; and to evaluate the relationship between clinical sleep disorders and blood pressure values in uremic patients. Results indicated that 85% of uremic patients undergoing hemodialysis complain of clinical insomnia (frequent, persistent and associated with daytime consequences) or sub-clinical sleep disorders; patients dialyzing in the morning sleep significantly less during the night preceding the treatment, than those dialyzing in the afternoon; older patients complaining of clinical insomnia have a higher risk of failure to achieve target-optimal values in systolic blood pressure.

RESUMEN

This study evaluated the effects of different amounts of sleep and SWS restriction on the ensuing day-time sleepiness. Six healthy selected males, after one adaptation night and an initial 8-hr baseline night, were allowed to sleep 5, 4, 3, 2, and 1 hr with a 1-week interval between conditions. The following day, 4 sleep onset MSLT trials and 2 Wilkinson Auditory Vigilance Task (WAVT) were administered. Before each MSLT, self evaluations of sleepiness and activation on a visual analogue scale (ADAS) were assessed. Each restriction night was followed by an 8-hr recovery night, and a final 8-hr baseline night was recorded. The day after each night the same diurnal tests were repeated. Results indicated a linear increase in the propensity to sleep (MSLT) and of subjective sleepiness as a function of the increase in sleep restrictions. Performance scores (WAVT) showed that vigilance is partially affected by sleep restrictions. For each measure, regression analyses showed that the effect of sleep reduction is better predicted by the total duration of sleep than by the amount of SWS. Correlations between measures were negligible with the exception of those between performance and subjective sleepiness measures.

RESUMEN

The study assessed the effects of different amounts of sleep restriction on slow wave sleep (SWS) in the ensuing recovery nights. After one adaptation night and an 8-hr baseline night, six healthy men were individually studied during and following five nights in which sleep was reduced to 5, 4, 3, 2, and 1 hr with a 1-week interval between conditions. Each sleep reduction was followed by an 8-hr recovery night. Finally, a second 8-hr baseline night was recorded. A trend analysis revealed that SWS amount in recovery nights increases with decreasing previous sleep duration. Regression analyses showed that, within each participant, the rebound of SWS after a sleep reduction is predicted better by the total duration of sleep than by the specific amount of SWS lost.
