Satisfaction with body weight among adolescents with excess weight: findings from a cross-sectional population-based study

ABSTRACT BACKGROUND: Individuals who are overweight or obese often underestimate their size, and they are less likely to consider their weight status to be a health problem and consequently to make lifestyle changes. OBJECTIVES: To estimate the proportion of satisfaction with weight among adolescents classified as overweight/obese, according to sociodemographic factors, morbidities and health-related behaviors. DESIGN AND SETTING: Cross-sectional population-based study conducted among adolescents aged 10 to 19 years in the city of Campinas (SP), Brazil. METHODS: The sample (n = 217) included participants with self-reported weight and height who were classified as overweight or obese, based on body mass index (BMI) according to age-specific cutoff points recommended by the World Health Organization. Participants whose answer to the question: "Would you like to gain or lose weight?" was "no" (i.e. no change) were deemed to be satisfied with their body weight. Odds ratios and 95% confidence intervals (95% CI) were calculated using logistic regression. RESULTS: The proportions of the respondents who were satisfied with their weight were 75.8% (95% CI: 65.3-83.9) among the overweight adolescents and 24.2% (95% CI: 16.1-34.7) among the obese adolescents (P < 0.01). Satisfaction was lower among individuals aged 15 to 19 years (versus 10 to 14 years), those born outside of Campinas (versus in Campinas), those with ≥ 8 household appliances (versus < 8), and those reporting ≥ two health complaints (versus none). CONCLUSIONS: More than half of the overweight adolescents and almost a quarter of the obese adolescents were satisfied with their weight. These results support the need for strategies for healthy weight management among Brazilian adolescents.

Distracted multinomial model for corona screening at entry ports

Background: On 24 January 2020, 1287 corona cases were noticed in Wuhan, China, causing 41 deaths. Its incubation period is at least 14 days. Now, this deadly virus has spread to other foreign countries. The prevalence of corona cases is changing daily. See www.who.org for daily reports. The corona cases are mystic and nightmare to the public, health professionals, and governing agencies globally.Methods: The Center for Disease Control (CDC) compiled in their webpage (www.cdc.org) the number of confirmed, number of healthy, and the number of pending cases at the port of entries in United States of America (USA). These numbers are perhaps under-estimates because of inappropriate diagnostics and imprecise incubation period. To resolve the under estimating, this article, introduces a distracted multinomial model to refine the imprecise corona screening process and interpret the probability of detecting a corona case in US entry gates.Results: An alternate expression (2) for the correlation between the corona ill and corona free cases at the USA ports of entry reveals that it was rising since 31st January 2020, reached its maximum on 5th February 2020, then declined to hit a bottom on 7th February 2020 only to rise again.Conclusions: Most desirable is an accurate predictability of a traveller with the corona virus at the portal entry to minimize its spread. To make such prediction, a regression is necessary with involvement of covariates like age, body’s immunity level, comorbidity, and precise understanding of its incubation period. The model in this article is the starting point for further future research work.

Underestimate the histologic grade by biopsy preoperative in bladder urotheliai carcinoma / 中华泌尿外科杂志

Objective To compare the histologic grade between biopsy and postoperative specimen in bladder urothelial carcinoma,and approach the state and the reasons of underestimate the histologic grade preoperative.Methods We retrospectively 82 cases of urothelial carcinoma at the Third Affiliated Hospi- tal of the Sun Yat-Sen University.For all the cases in this study,the histologic grade,using the 1998 World Health Organization and International Society of Urological Pathologists(WHO/ISUP)classification,was i- dentical when the biopsy specimen and postoperative specimen were compared.Results In this study,35 cases,28 cases and 19 cases were G_1、G_2、G_3 by biopsy preoperative,respectively;while 22 cases,32 cases、28 cases were G_1、G_2、G_3 postoperative,respectively.There were 24 cases(29.3%)underestimate the histo- logic grade by biopsy preoperative in the 82 cases,while 4 cases(4.9%)overestimate preoperative.The state of underestimate the histologic grade is correlated with the location of biopsy,tissue dose and the conser- vation of pathology judgment.Conclusions There were 24 cases(29.3%)underestimate the histologic grade by biopsy preoperative.We should pay more attention to this state of underestimate the histologic grade preoperative in the treatment of bladder urothelial carcinoma.
