Perceived social support and healthy eating self efficacy on the well-being of children and adolescents
Background: Unhealthy eating habits in children and adolescents and low personal judgment of efficacy in maintaining healthy eating behaviors have negative repercussions for health. These negative effects can have a differential affectation associated with psychosocial factors. Objectives/Method: The objectives were: to validate the Weight Efficacy Lifestyle (WEL) Questionnaire for Spanish children and adolescents; to analyze the relationship between well-being, socioeconomic level, body mass index, age, academic distress, social support for healthy and unhealthy eating, and self-efficacy; and to develop an explanatory model of well-being in children and adolescents based on their eating behaviors and other psychosocial behaviors. Results: Data were obtained from 299 children and adolescents (58.5% girls) aged from 9 to 18 years old (M-age = 12.92 years, SD = 2.74). Preliminary analysis showed adequate psychometric properties and results showed that perceived well-being was associated with lower academic distress and parent and peer social support for unhealthy eating, and with a better eating self-efficacy, parent support for healthy eating, and general weight management self-efficacy. Conclusions: Therefore, fostering confidence in children and adolescents about their weight management self-efficacy judgments may influence well-being, reduce body mass index, and prevent overweight and obesity
Influenza Epidemiology And Influenza Vaccine Effectiveness During The 2016-2017 Season In The Global Influenza Hospital Surveillance Network (Gihsn)
BackgroundThe Global Influenza Hospital Surveillance Network (GIHSN) aims to determine the burden of severe influenza disease and Influenza Vaccine Effectiveness (IVE). This is a prospective, active surveillance and hospital-based epidemiological study to collect epidemiological data in the GIHSN. In the 2016-2017 influenza season, 15 sites in 14 countries participated in the GIHSN, although the analyses could not be performed in 2 sites. A common core protocol was used in order to make results comparable. Here we present the results of the GIHSN 2016-2017 influenza season.MethodsA RT-PCR test was performed to all patients that accomplished the requirements detailed on a common core protocol. Patients admitted were included in the study after signing the informed consent, if they were residents, not institutionalised, not discharged in the previous 30days from other hospitalisation with symptoms onset within the 7days prior to admission. Patients 5years old or more must also complied the Influenza-Like Illness definition. A test negative-design was implemented to perform IVE analysis. IVE was estimated using a logistic regression model, with the formula IVE=(1-aOR)x100, where aOR is the adjusted Odds Ratio comparing cases and controls.ResultsAmong 21,967 screened patients, 10,140 (46.16%) were included, as they accomplished the inclusion criteria, and tested, and therefore 11,827 (53.84%) patients were excluded. Around 60% of all patients included with laboratory results were recruited at 3 sites. The predominant strain was A(H3N2), detected in 63.6% of the cases (1840 patients), followed by B/Victoria, in 21.3% of the cases (618 patients). There were 2895 influenza positive patients (28.6% of the included patients). A(H1N1)pdm09 strain was mainly found in Mexico. IVE could only be performed in 6 sites separately. Overall IVE was 27.24 (95% CI 15.62-37.27. Vaccination seemed to confer better protection against influenza B and in people 2-4years, or 85years old or older. The aOR for hospitalized and testing positive for influenza was 3.02 (95% CI 1.59-5.76) comparing pregnant with non-pregnant women.ConclusionsVaccination prevented around 1 in 4 hospitalisations with influenza. Sparse numbers didn't allow estimating IVE in all sites separately. Pregnancy was found a risk factor for influenza, having 3 times more risk of being admitted with influenza for pregnant women.Wo
