ABSTRACT Objective: To identify the prevalence of overweight in adolescents according to different classification criteria for obesity and somatic maturation stages. Methods: Cross-sectional study in 10 schools in a city from Southern Brazil, with 1715 adolescents. Height, weight, waist circumference, and neck circumference (NC) data were collected. Body Mass Index was classified according to World Health Organization (WHO) and Centers for Disease Control and Prevention criteria, and the waist-to-height ratio (WHtR) was classified according to Brazilian and European cut-off points. Somatic maturation was obtained through the Peak Height Velocity. The prevalence data were compared between sex and stages of somatic maturation; the concordance between different criteria was verified. Results: The prevalence of overweight was high in both sexes; WHO criteria showed that 34.5% of boys and 29.3% of girls were overweight. For the WHtR, the prevalence was 28.4% in boys and 23.7% in girls. NC classified 13.8% of boys and 15.8% of girls as being overweight. The prevalence of overweight was higher in adolescents before complete somatic maturation. Conclusions: The prevalence of overweight was high among adolescents. The boys presented higher frequency of overweight, except if NC was used to classify them. Adolescents before somatic maturation had a higher prevalence of overweight. NC showed a lower ability to track obese adolescents.

ABSTRACT CONTEXT AND OBJECTIVE: Peak height velocity (PHV) is an important maturational event during adolescence that affects skeleton size. The objective here was to compare bone variables in adolescents who practiced different types of sports, and to identify whether differences in bone variables attributed to sports practice were dependent on somatic maturation status. DESIGN AND SETTING: Cross-sectional study, São Paulo State University (UNESP). METHODS: The study was composed of 93 adolescents (12 to 16.5 years old), divided into three groups: no-sport group (n = 42), soccer/basketball group (n = 26) and swimming group (n = 25). Bone mineral density and content were measured using dual-energy x-ray absorptiometry and somatic maturation was estimated through using peak height velocity. Data on training load were provided by the coaches. RESULTS: Adolescents whose PHV occurred at an older age presented higher bone mineral density in their upper limbs (P = 0.018). After adjustments for confounders, such as somatic maturation, the swimmers presented lower values for bone mineral density in their lower limbs, spine and whole body. Only the bone mineral density in the upper limbs was similar between the groups. There was a negative relationship between whole-body bone mineral content and the weekly training hours (β: -1563.967; 95% confidence interval, CI: -2916.484 to -211.450). CONCLUSION: The differences in bone variables attributed to sport practice occurred independently of maturation, while high training load in situations of hypogravity seemed to be related to lower bone mass in swimmers.

Abstract Objectives: This study aimed to examine age-specific trends in the prevalence of overweight and obesity in schoolchildren in Kuwait over a 13-year period (2007 to 2019) using the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC) and the International Obesity Taskforce (IOTF) definitions. Design: Using cross-sectional approach, Kuwait Nutrition Surveillance System (KNSS) objectively measured weight and height of schoolchildren over a 13-year period. Log-binomial regression models were used to examine age-specific trends of obesity and overweight over the study period. Setting: Public primary, middle, and high schools in all provinces of Kuwait. Participants: Schoolchildren aged 5-19 years (N 172 603) Results: According to the WHO definition, the prevalence of overweight and obesity in schoolchildren respectively increased from 17.73% and 21.37% in 2007 to 20.19% and 28.39% in 2019 (P for trends<0.001). There is evidence that the obesity in females (but not males) has levelled off in the period 2014-2019 according to the three definitions of obesity, which is corroborated by a similar trend in the mean of BMI-for-age Z score. Conclusion: The prevalence of obesity and overweight in schoolchildren in Kuwait has risen over the last 13 years and trends are similar across all definitions. Obesity is no longer increasing at the same pace and there is evidence that the prevalence of obesity in females has plateaued. The current level of childhood overweight and obesity is too high and requires community-based and school-based interventions.

Abstract Background Coronavirus disease-2019 (COVID-19) is a life-threatening global pandemic. The dental profession is considered a high-risk group in the transmission of the responsible virus. Objective To assess the knowledge and attitude among dental professionals in response to the COVID-19 pandemic. Methods We conducted a cross-sectional study of dental graduates, interns, postgraduates, and dental faculty from May to July 2020. A standardized questionnaire was developed to assess knowledge and attitude of 650 participants. The questionnaire comprised 14 questions to assess general knowledge about COVID-19, 11 questions regarding knowledge about prevention of COVID-19 in dental practice, and 10 questions regarding the attitude toward preventing COVID-19. Results Among the study population, only 376 (57.8%) knew the causative virus for COVID-19. Only 425 (65.3%) knew about rinsing the mouth with an antimicrobial solution or 1% hydrogen peroxide before the dental procedure. Regarding the hand hygiene guidelines, 357 (54.9%) had knowledge of the Centers for Disease Control and Prevention (CDC) and 377 (58.0%) about World Health Organization (WHO) guidelines. At the time of our survey, 72% of the participants showed sufficient knowledge, while 28% had low or insufficient knowledge about COVID-19. Conclusion While there was a lack of knowledge among dental professionals in Riyadh, Saudi Arabia about COVID-19, there was an excellent positive attitude toward preventing disease. Greater awareness is needed to control the spread of this disease.

Cardiorespiratory fitness is an important health status indicator. The purpose of this study was to verify the cardiorespiratory fitness according to age group and gender in children and adolescents from Sergipe, Brazil. It is a cross-sectional study with sample consisting of 195 adolescents of both genders with mean age of 11.75 ± 3.0 years. For the characterization of participants, a questionnaire with age and gender identification designed by researchers was used. Subsequently, participants were submitted to anthropometric evaluation in order to estimate the maturational stage by means of the peak height velocity (PHV). The 20-meter back-and-forth test was used to estimate cardiorespiratory fitness. Two-way ANOVA was applied with sample divided into two groups (“up to 13 years” and “above 13 years”). Polynomial contrast was used to identify the type of tendency for cardiorespiratory fitness, and simple contrast for multiple comparisons. All procedures were performed using SPSS version 22.0 software, considering 5% significance level. In the “over 13 years” group, there was a significant effect on the cardiorespiratory capacity behavior according to “gender” [F(1, 45) = 5.54, p = 0.02, r = 0.33] and “age” [F(4.45) = 3.37, p = 0.02, r = 0.48]. The simple contrast identified increased cardiorespiratory fitness behavior in relation to age groups of 15 and 16 year when compared to the age group of 14 years. It was concluded that gender and age positively influence cardiorespiratory fitness from the maturational reference age in the study group.

Background Over the past decade, there has been an increasing secular trend in the number of studies on social media and health. Objective The purpose of this cross-sectional study was to examine the content and characteristics of TikTok videos that are related to an important aspect of community mitigation—the use of masks as a method for interrupting the transmission of SARS-CoV-2. Methods In total, 100 trending videos with the hashtag #WearAMask (ie, a campaign on TikTok), along with 32 videos that were posted by the World Health Organization (WHO) and involved masks in any way (ie, all related WHO videos at the time of this study), were included in our sample. We collected the metadata of each post, and created content categories based on fact sheets that were provided by the WHO and the US Centers for Disease Control and Prevention. We used these fact sheets to code the characteristics of mask use. Results Videos that were posted on TikTok and had the hashtag #WearAMask garnered almost 500 million views, and videos that were posted by the WHO garnered almost 57 million views. Although the ratio of the number of trending #WearAMask videos to the number of WHO videos was around 3:1, the #WearAMask videos received almost 10 times as many cumulative views as the WHO videos. In total, 68% (68/100) of the trending #WearAMask videos involved humor and garnered over 355 million cumulative views. However, only 9% (3/32) of the WHO videos involved humor. Furthermore, 27% (27/100) of the trending #WearAMask videos involved dance and garnered over 130 million cumulative views, whereas none of the WHO videos involved dance. Conclusions This study is one of the first to describe how TikTok is being used to mitigate the community spread of COVID-19 by promoting mask use. Due to the platform’s incredible reach, TikTok has great potential in conveying important public health messages to various segments of the population.

Metadata on each post and content categories created using fact sheets from WHO and the US Centers for Disease Control and Prevention (CDC) inform characteristics that were coded. RESULTS Videos posted using the hashtag #WearAMask garnered almost a half billion views, (n = 494,824,395) and videos posted by the WHO garnered over 57 million views. While the ratio of trending #WearAMask to WHO videos was ~3:1, the #WearAMask videos received almost 10 times as many cumulative views. A total of 68% of the trending #WearAMask videos used humor (garnering over 355 million cumulative views), but only three of the WHO videos used humor, and while 27% of the trending #WearAMask videos used dance (garnering over 130 million cumulative views), none of the WHO videos used dance. CONCLUSIONS This study is one of the first to describe how TikTok is being used for community mitigation of COVID-19 by promoting mask use. Because of its incredible reach, there is great potential to convey important public health messages to various segments of the population.

Background:: Rational drug use comprises aspects of prescribing, dispensing and patient use of medicines for different health problems. This study is aimed to assess drug prescribing practice based on the world health organization prescribing indicators in Mizan-Tepi University teaching hospital. Methods:: An institutional based retrospective cross sectional study was conducted to evaluate prescribing practices in Mizan-Tepi University teaching hospital. Data were collected based on World health organization drug use indicators using prescription papers. 600 prescriptions dispensed through the general outpatient pharmacy of the hospital were collected by systematic random sampling method from prescriptions written for a 1-year time in Mizan-Tepi University teaching hospital. Results:: The present study found that the average number of drugs per prescription was 2.04 ± 0.87 in Mizan-Tepi University teaching hospital with a range between 1 and 5. Prescribing by generic name was 97.6 % and 47.8% of prescriptions contained antibiotics in the hospital. 27.7% of prescriptions contained at least one injectable medication in Mizan-Tepi University teaching hospital. From prescribed drugs, 96.7% of them were prescribed from Ethiopian essential drug list. Conclusion:: Present study indicated that the average number of drugs prescribed per encounter, the percentage of generic prescribing and prescribing from the EDL were close to optimal value. However, the percentage of encounters with antibiotics and injections prescribed were found be very high. Thus, the study highlights some improvements in prescribing habits, particularly by focusing on the inappropriate consumption of antibiotics and injections.

Abstract Background The World Health Organization recognizes exclusive breastfeeding a safe source of nutrition available for children in most humanitarian emergencies, as in the current pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Despite the Brazilian national guideline protecting breastfeeding practices, there are many concerns about protecting infants from their infected mothers. This study aimed to analyze how the Brazilian hospitals and maternity services promote and support mothers suspected or diagnosed with coronavirus disease (COVID-19). Methods This is a descriptive cross-sectional and multicenter study which collected data from 24 Brazilian hospitals and maternity services between March and July 2020. Representatives of the institutions completed a questionnaire based on acts to promote and support breastfeeding, the Baby-Friendly Hospital Initiative, and Brazil’s federal law recommendations. Results The results showed that in delivery rooms, 98.5% of the services prohibited immediate and uninterrupted skin-to-skin contact between mothers and their infants and did not support mothers to initiate breastfeeding in the first hour. On the postnatal ward, 98.5% of the services allowed breastfeeding while implementing respiratory hygiene practices to prevent transmission of COVID-19. Companions for mothers were forbidden in 83.3% of the hospitals. Hospital discharge was mostly between 24 and 28 h (79.1%); discharge guidelines were not individualized. Additionally, a lack of support was noticed from the home environment’s health community network (83.3%). Hospital and home breast pumping were allowed (87.5%), but breast milk donation was not accepted (95.8%). There was a lack of guidance regarding the use of infant comforting strategies. Guidelines specific for vulnerable populations were not covered in the material evaluated. Conclusions In Brazil, hospitals have not followed recommendations to protect, promote, and support breastfeeding during the COVID-19 outbreak. The disagreement between international guidelines has been a major issue. The absence of recommendations on breastfeeding support during the pandemic led to difficulties in developing standards among hospitals in different regions of Brazil and other countries worldwide. The scientific community needs to discuss how to improve maternal and infant care services to protect breastfeeding in the current pandemic.

Relevant personal protective measures during the COVID-19 pandemic include face masks, possibly decreasing the risk of infection among the general population and healthcare workers (HCW) if utilized properly. The aim of the study was to assess whether different Polish HCW utilize face masks according to the 2020 World Health Organization guidance (WHO) criteria. This cross-sectional study included 1156 respondents who participated in an internet survey evaluating mask-related behaviors. All the WHO criteria were complied with by 1.4% of participants, regardless of medical profession, specialty or place of employment. HCW mostly adhered to criterion 1 (C1; strict covering of the face and mouth with the mask; 90.8%), C4 (washing/disinfecting the hands after touching/taking off the mask; 49%) and C3 (taking off the mask properly without touching the anterior surface; 43.4%), whereas C2 (avoidance of touching the mask with hands) was complied with least commonly (6.8%). HCW with mask-induced itch (31.6%) complied to C2 less often (odds ratio 0.53; p = 0.01). The study reveals that Polish HCW rarely adhere to all the 2020 WHO guidance criteria on the use of masks, whereas the adherence to particular criteria is variable and may be associated with the presence of skin-related conditions and other factors. Better compliance with the recommendations in the future is necessary to increase personal safety of HCW and prevent the transmission of SARS-CoV-2.

Background: COVID-19 is a severe respiratory virus that spreads via person-to-person contact through respiratory droplets. Since being declared a pandemic in early March 2020, the World Health Organization had yet to release guidelines regarding the return of college or professional sports for the 2020-2021 season. Purpose: To survey the head orthopedic surgeons and primary care team physicians for the National Collegiate Athletic Association (NCAA) Football Bowl Subdivision (FBS) football teams so as to gauge the management of common COVID-19 issues for the fall 2020 college football season. Study Design: Cross-sectional study. Methods: The head team orthopaedic surgeons and primary care physicians for all 130 FBS football teams were surveyed regarding their opinions on the management of college football during the COVID-19 pandemic. A total of 30 questions regarding testing, return-to-play protocol, isolating athletes, and other management issues were posed via email survey sent on June 5, 2020. Results: Of the 210 team physicians surveyed, 103 (49%) completed the questionnaire. Overall, 36.9% of respondents felt that it was unsafe for college athletes to return to playing football during fall 2020. While the majority of football programs (96.1%) were testing athletes for COVID-19 as they returned to campus, only 78.6% of programs required athletes to undergo a mandatory quarantine period before resuming involvement in athletic department activities. Of the programs that were quarantining their players upon return to campus, 20% did so for 1 week, 20% for 2 weeks, and 32.9% quarantined their athletes until they had a negative COVID-19 test. Conclusion: While US Centers for Disease Control and Prevention guidelines evolve and geographic regions experience a range of COVID-19 infections, determining a universal strategy for return to socialization and participation in sports remains a challenge. The current study highlighted areas of consensus and strong agreement, but the results also demonstrated a need for clarity and consistency in operations, leadership, and guidance for medical professionals in multiple areas as they attempt to safely mitigate risk for college football players amid the COVID-19 pandemic.
