Background and objectives: a deterioration of health habits has been found in various studies caused by stressful situations such as mandatory and maintained confinement over time. This study aims to analyze the health habits of the Spanish adult population during confinement due to the COVID-19 pandemic, and the possible impact on their body weight. Method: two thousand eight hundred and thirty-four volunteer subjects participated in the study (69.3 % women). They completed an on-line questionnaire that evaluated their health habits, as well as various sociodemographic variables. Results: the results show a statistically significant link between the subjects' body mass index (BMI) and the change in their weight during lockdown (2: 79.303; p: < 0.001). Besides, a statisti-cally significant relationship between the different health habits under analysis was also found, being moderate with respect to the link between eating habits and physical activity (Cramer's V: 0.226). A statistically significant relationship was also found between the participants' weight and the different health habits during lockdown. The effect size of the associations was moderate in relation to the participants' eating habits (Cramer's V: 0.409) and physical activity (Cramer's V: 0.292). Conclusions: it is suggested the development of prevention programs for long lockdown periods associated with high levels of stress so as to promote a healthy diet, as well as exercise using new technologies and a proper rest, especially in overweight or obese subjects.

Introduction: obesity is currently one of the most important international health problems, and the study of the various aspects related to it has become a priority. One such aspect is the analysis of the weight bias internalization, especially its evaluation, for which different instruments hare been designed, though they are not available for Spanish population.Objectives: the objective of this study is the translation and adaptation of the Weight Bias Internalization Scale (WBIS), analyzing its psychometric characteristics.Methodology: fifty-nine people were evaluated by a Spanish adaptation of WBIS, the Beck Depression Inventory (BDI) in short version, and the General Health Questionnaire Goldberg (GHQ-28). Internal consistency was explored, as well as concurrent and construct validity of the adapted instrument.Results: Cronbach's alpha coefficient was .89, while the concurrent validity showed statistically significant correlations with the total score of GHQ-28 (r = .39, p < .02) and the BDI (r = .42, p < .001). The final scale consists of 11 items, which are grouped into two main factors, and allow a significant explanation of 65.03% of the variance.Conclusions: the Spanish adaptation of the WBIS shows good psychometric values of reliability and validity, so it might be a good scale for the assessment of the weight bias internalization, which could be confirmed in larger studies.

Background: Overweight and obesity are a worldwide health problem. There are few researches about the prevalence of these conditions in penitentiaries; that is why this study aims at determining prevalence in a sample of inmates at a Spanish penitentiary. Methods and materials: 122 inmates from a Spanish penitentiary volunteered for this research in which 99 were men (81.1%) and 23 were women (18.9%), and the average age was 36.2 (DT 11.03). Weight and size measures were collected, and the body mass index (BMI) was assessed. Results: 56.6 % of inmates are overweighed or obese, which is slightly below the prevalence values among the Spanish population. No significant differences can be observed in the prevalence of overweight or obesity between men and women. Debate: The results show that there are high levels of overweight and/or obesity prevalence among penitentiary inmates, matching the results from other international studies. This should encourage the implementation of prevention and/or intervention programs. [ABSTRACT FROM AUTHOR]

Introduction: In the children obesity research field, weighing and measuring involves high research costs, which could be reduced if the self-reported body mass index (BMI) was ascertained to be a valid index. Objective: To analyze the accuracy of children's selfreported BMI. Materials and methods: 171 school students from Madrid participated in the study (Mean age: 10,68 years). They were weighed and measured, and were also asked to report their weight and height. Both current and selfreported BMI were calculated. Results: The correlation between self-reported BMI and the current BMI was r = .803 (p < .001), and the kappa indexex ranged from k = .38 to .46. Conclusions: The self-reported BMI noticeably coincide with the current BMI in 10 to 11 year-old children. However, a modest concordance was found between the categorization within a weight-related group (normal, overweight and obese) based on both indexes, which shows the former could be a valid measure when carrying out population studies on obesity and overweight.
